1 Introduction
The ASEAN economies have grown considerably, doubling its share of the world’s gross domestic product (GDP) from 3.3 per cent in 1967 to 6.2 per cent in 2016 (World Bank), making it the sixth-largest economic group in the world. In recent years, policymakers in the ASEAN economies are committed to promote further regional integration and growth through the ASEAN Economic Community Blueprint that aims to promote ASEAN as a competitive single market economic region by 2025 (ASEAN Secretariat
2008). An important part of the initiative involves financial development and integration efforts in the region in order to promote further economic growth. In general, there is a consensus that financial development promotes economic growth, through the seminal work by King and Levine (
1993) alongside many consequent empirical studies. Financial systems reduce information and transaction costs which allow intermediaries and markets to mobilise savings, allocate resources and facilitate risk management leading to capital accumulation and technological progress for economic growth (Levine
1997). However, a number of studies have suggested that the role of finance in economic growth is weakening and, in some cases, negative, as there may be other factors, such as institutional quality that influences the positive effects of finance on growth (Breitenlechner et al.
2015; Rousseau and Wachtel
2011). Therefore, the initiatives of the ASEAN economies to push financial development and integration make it a compelling study for the examination of the relationship between finance and growth, particularly as there are recent studies that provide evidence against the positive effects of finance.
This study examines several issues regarding the relationship between financial and institutional development to economic growth. First, the study examines the role of finance and institutions in the context of the ASEAN economies from 1995 to 2017, as the region is understudied in terms of the empirical contribution of finance and institutions to economic growth. The study employs a dynamic panel estimator to control for endogeneity. More importantly, the study distinguishes the extent of the contribution from financial markets and financial institutions. The finance-growth literature has argued that different financial structures, such as the bank-based or market-based financial systems, can be beneficial for economies at different stages of economic development (Cull and Xu
2013; Deidda and Fattouh
2008; Hondroyiannis et al.
2005). The ASEAN economies are a diverse group of countries with varying levels of economic development that includes both developed and developing economies and thus, will be interesting to examine the role of financial structures on economic growth. Finally, the study examines the effects of institutional development on economic growth and its impact on financial development. Many studies have provided evidence of the instrumental role of institutions on economic growth such as the rule of law and governance in an economy (La Porta et al.
1998). As the ASEAN economies are diverse in terms of its economic development, it will be important to examine the contribution of institutional development alongside financial development on economic growth.
The novelty of the study lies in the use of indices to examine the relationship between finance and institution on economic growth. Previous studies that examine the relationship between financial development and economic growth have traditionally employed variables that measure financial depth, such as the ratio of bank credit to GDP for financial institutions (Levine
1997) or the value of stocks traded to GDP for financial markets (Levine and Zervos
1998). This study employs an index of financial institutions and financial markets proposed by Svirydzenka (
2016), which considers the depth, accessibility and efficiency of the respective financial structure and thus, provides a better measure for overall financial development. In addition, this study employs an index for institutional development proposed from the World Governance Indicators (World Bank). More specifically, the study examines the effects of the rule of law index on economic growth and examines the interaction of this index with the financial structure indices. As a result, this study contributes new evidence on the empirical work on the relationship between finance and institutions to economic growth in the context of the ASEAN economies, which has been understudied. This provides important implications for future policies as the ASEAN economies are committed to developing an integrated ASEAN Economic Community that includes extensive financial and institutional development and integration across the region.
The following sections will be organised as follows. Section

2 Role of finance and institutions in economic growth
The relationship between finance and economic growth has been discussed for decades. Early theoretical work by Schumpeter (
1911) highlights the importance of financial development in spurring economic growth, alongside empirical studies by Goldsmith (
1969), and subsequently King and Levine (
1993), supported the view that financial development is a good predictor of economic growth. Financial systems consist of intermediaries and markets with functions that promote channels to economic growth through capital accumulation and technological progress (Levine
1997). These functions include acquiring information, exerting corporate governance, managing risk, facilitating exchange and mobilising savings. Thus, financial development is suggested to nurture economic growth through the various functions that financial systems provide. However, financial systems consist of intermediaries and markets which raises the question of which performs the functions more effectively. This led to the debate on the bank-based versus market-based financial system.
Previous researches stressed the advantages that financial intermediaries have over markets in terms of the efficient allocation of capital. Intermediaries are able to finance and exploit economies of scale and scope more effectively in underdeveloped economies and can easily commit additional finance on projects (Stulz
2002). Furthermore, it was suggested that intermediaries outperform a market-based system particularly for developing countries, where intermediaries allow for a more equitable distribution of income (Chakraborty and Ray
2006) and promote physical and human capital investment in poorer countries (Cull and Xu
2013). In addition, it is suggested that bank financing supports the growth of smaller firms (Beck et al.
2008), while others emphasise the importance of a strong banking sector in order to reduce information asymmetry between buyers and sellers (Strieborny and Kukenova
2015). Finally, although both banks and markets contribute to economic growth, banking development is suggested to be better for long-term economic growth (Arestis et al.
2001).
In contrast, there are researches that argue for the case of a market-based financial system. Theoretically, it is argued that efficient markets are more effective as it reduces the need for investors to research firms as new information will be reflected in public stock prices (Stiglitz
1985). Additionally, banks are more biased towards conservative investments and thus will be less effective at promoting innovation and growth compared to markets (Morck and Nakamura
1999). Furthermore, some dominant banks in developing countries, such as state-owned banks, are less interested in performing financial functions and are more focused on political goals while extracting rents (Rajan
1992). Other research highlights the effectiveness of financial markets in promoting corporate governance, particularly in equity markets through the hostile takeovers of under-performing firms (Scharfstein
1988).
Despite the arguments for an optimal financial structure, the empirical evidence seems to be mixed and there is no consensus for a bank-based or market-based financial system. Early empirical work suggests that both financial structures are positive and significant to economic growth (Levine and Zervos
1998) and emphasise that the aim of financial development is to enhance the functions it performs. Consequent empirical work supported this view and stressed that overall financial development is important as banks and markets can be complementary to one another, allowing for further capital accumulation and technological progress (Huybens and Smith
1999). Banks and markets are suggested to produce different growth paths as markets are more related to long-term financing, while banks are able to finance for both short- and long-term projects (Demirgüç-Kunt and Maksimovic
2002).
However, the differences in the effectiveness of financial structures on economic growth suggests that there may be other factors that can affect this relationship, such as the institutional development of the country. For example, recent research has shown support for stock market development particularly for highly developed countries with strong institutions (Peia and Roszbach
2015). Furthermore, it is also suggested that advanced economies benefit more from market-based financial systems compared to less-developed countries, where bank-based financial systems affect growth more effectively due to lack of access to finance (Cull and Xu
2013). Thus, various researches have argued for the merits of a bank-based and market-based system; however, the lack of consensus suggests that other factors such as institutional development must be considered (La Porta et al.
2008).
Institutions are a loosely based term that includes financial intermediaries and markets, and as such, this study refers to institutions as those that do not include banks and financial markets. Institutions can be defined as human-developed constraints that structure interaction and can be made up of formal and informal organisations with enforcement characteristics (Rodrik
2000). For example, these can range from formal institutions such as political stability, regulatory quality and the rule or law to informal institutions such as cultural norms in social interactions and religion. In theory, formal institutions can provide incentives for agents that can be beneficial for economic growth. An essential institution that is well established in the literature is the rule of law. It is suggested that legal frameworks and origins matter can indirectly affect financial development and has a positive effect on economic growth (La Porta et al.
2000). Furthermore, a well-functioning and reliable legal system is crucial in enforcing property rights and other market-oriented institutions to perform effectively for economic growth (Berggren and Jordahl
2005).
Previous studies emphasise the role of the legal system in promoting financial development as enforcement provides protection for investors which promotes further capital allocation and investment (Beck and Levine
2002). More specifically, legal systems reduce moral hazard in both bank-based and market-based systems which ease potential constraints for borrowers to acquire financing (Chakraborty and Ray
2006). On the other hand, empirical studies on the effectiveness of legal institutions are varied as countries experience different growth paths. For example, recent studies find that the effectiveness of legal institutions does not promote stock market development in Sub-Saharan Africa due to the presence of weak legal institutions (Aluko and Azeez
2018). This is important to consider in the case of the ASEAN economies, which consists of a number of developing countries that are undergoing structural changes. Other empirical studies find that economic freedom indices such as an optimal government size, flexible regulations and a strong rule of law can exert beneficial impacts on income (Pattanaik and Nayak
2014). Finally, other empirical studies examine the impact of financial development on institutions, which can indirectly increase growth. Dutta and Mukherjee (
2018) suggest that greater financial development can encourage a transparent banking system with strong governance, which increases transparency in the legal environment thus leading to stronger institutional development. As a result, it is important to consider the interaction effects between financial development and institutions as both can have indirect impacts on economic growth.
3 Development of the ASEAN economies
The ASEAN economies are a geopolitical and economic organisation established in 1967 by five member states. Today, the organisation is made up of 10 countries that include Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, Philippines, Singapore, Thailand and Viet Nam. The aims and purpose of the organisation are to promote and advance economic, social and cultural development through collaborative efforts and initiatives while maintaining peace and stability (ASEAN Secretariat
2008). The ASEAN economies have grown considerably since its inception in 1967, doubling its share of the world’s GDP from 3.3 per cent in 1967 to 6.2 per cent in 2016 (ASEAN Secretariat
2018). Furthermore, in 2016, the ASEAN economies as a group have a total young population of 600 million, alongside a high savings rate. As a result, the ASEAN economies display a strong potential to develop further. Despite its strong economic performance, early researches criticised that the growth of the ASEAN economies was mainly driven by capital inputs, which is not sustainable in the long-run, as the effects of capital investments will diminish over time (Krugman
1994). Furthermore, other researches argued that the ASEAN economies depended on external trade, as growth was primarily driven by technological progress and transfer through trade openness and foreign direct investment in the region, particularly after the establishment of the ASEAN Free Trade Area in 1993 (Lee and Tan
2006).
However, after the Asian financial crisis in 1997, the ASEAN economies shifted from market-driven institutions to institutional-based regional integration, which was a loose form of regional economic integration as there is an absence of formal cooperative scheme (Nicolas
2008). One of the earliest efforts of financial integration in the region was the Chiang Mai Initiative, which was implemented in 2000 (ASEAN Secretariat
2008). The Chiang Mai Initiative created a network of currency swaps between the ASEAN economies and other neighbouring countries, which provided stability and effectively safeguarded the region from illiquidity and contagion. As a result, financial development in the ASEAN economies was driven by institutional arrangements. In addition to the Chiang Mai Initiative, the ASEAN economies further emphasised on financial stability with the creation of the ASEAN Surveillance Process (Almekinders et al.
2015). In 2003, the ASEAN economies began the development of a regional bond market leading to the creation of the Asian Bond Fund and the Asian Bond Market Initiative, where one addresses demands and the other addresses supply, respectively (Nicolas
2008). However, these financial integration and development efforts still lag behind the financial and monetary integration in the European Union, as the initiatives employed by the ASEAN economies were focused on stability as a result of the Asian Financial Crisis.
In recent years, policymakers in the ASEAN economies have continued to develop initiatives in order to advance the aims and purpose of the organisation. The ASEAN Economic Community Blueprint highlights the region’s commitment towards the freer movement of goods and services, attracting foreign direct investment and skilled labour alongside the freer flow of capital (Petri et al.
2012). This can potentially enhance the profile of the ASEAN economies as an important player in the global economy and compete with those of the European Union despite the absence of a shared monetary union and currency. A major initiative discussed within the ASEAN Economic Community Blueprint is the issue of deeper financial integration and development within the region. These include the development of an ASEAN Capital Markets Forum, ASEAN Banking Integration Framework, Working Committee on Capital Account Liberalisation and Working Committee on Payment and Settlement System, which places emphasis on both the integration and development of financial institutions and financial markets (Almekinders et al.
2015).
These initiatives focus on the harmonisation of domestic laws and regulation that can promote regional integration and development leading to the freer flow of capital. In addition, the ASEAN economies emphasise on building financial inclusion and stability measures to reduce inequality and promote overall growth. However, many of these initiatives are still loose when compared to the regional integration efforts such as the European Union. For example, bilateral banking integration is low in the region since domestic banks still dominate the financial systems in the respective ASEAN countries (Almekinders et al.
2015). As a result, the region introduced a framework based on the single passport banks in the European Union in the form of the Qualified ASEAN Bank initiative (Rillo
2018). These regional integration efforts can encourage further financial development as it promotes cross-border movement of capital and provides greater market access to the region and ultimately increase economic growth.
Achieving financial development and integration, however, requires liberalisation policies that are sustainable and can mitigate potential risks of credit booms and volatile capital flows. Countries with weak policies and institutions may be vulnerable to the risks of capital account liberalisation and thus, should focus on building strong institutions (Prasad and Rajan
2008). Furthermore, excessive deregulation can increase the frequency of boom and bust cycles (Beck et al.
2014). The ASEAN economies have experienced the Asian Financial Crisis during 1997, where macroeconomic imbalances have reduced capital inflows while capital outflows have caused currencies to depreciate within the region (Thanoon and Baharumshah
2005). The potential risks from financial liberalisation and integration must be mitigated in order to avoid such events. For example, cross-border banking and the integration of regional banks are instrumental in Africa’s development, changing its financial system rapidly over the past decade (Beck
2015).
As a result, it is important to understand the financial and institutional landscape of the individual ASEAN member states to evaluate the development of the individual economies. Table
1 presents the financial and institutional development indices for the ASEAN member states. It can be observed that the ASEAN economies are highly diverse in their development of finance and institutions. Unsurprisingly, the least developed ASEAN economies in overall financial development are Viet Nam, Cambodia, Myanmar and Lao PDR with a low rule of law Index. As expected, the four original ASEAN economies, Singapore, Thailand, Malaysia and the Philippines, are ahead in both finance and institutional development. Thus, it is important to consider that the economies are at different stages of development when implementing policies for regional integration, as the developed economies will benefit more than their less-developed counterparts. On the one hand, the overall level of financial and institutional development shows an improvement from 1995 to 2017. This suggests that the loose regional integration policies implemented by the ASEAN economies may be effective in the region.

Lao PDR | 0.116 | 0.139 | 0.195 | 0.173 | 0.035 | 0.101 | − 1.124 | − 0.881 |
Thus, it is suggested that there are important prerequisites that must be in place before financial reforms and integration can be successful, which includes institutional reform, stable macroeconomic environment, policy credibility and effective and adequate monetary supervision (Fowowe
2013). Similarly, recent research has emphasised the role of institutional quality in promoting economic growth in the ASEAN economies (Masron
2017). Interestingly, developing strong financial institutions can promote transparency which leads to a positive feedback effect on economic growth, as a more transparent economy attracts higher levels of foreign direct investment (Dutta and Mukherjee
2018). Hence, it is essential to investigate and understand the role of financial and institutional development in economic growth, in order to identify appropriate policies that can accelerate the goals of the ASEAN Economic Community Blueprint.

The correlation matrix measures the linear relationship between two variables, where +1 results in two perfectly positively correlated variables, while − 1 means two perfectly negatively correlated variables. This provides some understanding of the variables employed and can provide some insight prior to the estimated dynamic panel model. Real capital per labour (
k) is associated with real GDP per labour (
y), which is expected and is consistent with the production function theory as GDP is a function of capital and labour (Haini
2019). Meanwhile, the other independent variables display a moderate correlation to
y with the exception for the rule of law (law). Interestingly, the fi exhibits a stronger correlation with
y, compared to fm, which suggest that the effects of financial institutions may be more effective in spurring economic growth.
Meanwhile, focusing on fi and fm, the correlation between the two financial development indices is positive and strong. Although both variables are different in nature, as the index for financial institutions focuses on banks, mutual funds, pension funds and insurance, while index for financial markets focuses on stock market size, activity and volumes of government and private debt securities (Svirydzenka
2016). However, both indices can still be highly correlated due to the demand-following hypothesis, which postulates a causal relationship from real growth to financial development, whereby there will be an increase in demand for financial services as the real sector develops (Patrick
1966). As a result, it will be sensible to investigate the role of financial institutions and financial markets in separate specifications in order to examine the contribution of the individual financial structure on economic growth.
The estimated model coefficients of the system GMM estimations are reported in Table
4. The estimated results are robust as they satisfy the conditions of the Arellano–Bond test of no autocorrelation at the second order. Furthermore, the GMM estimations pass the Sargan test for the validity of the instruments. In addition, a production function must have monotonicity properties before it can be reasonably interpreted (Henningsen and Henning
2009). In this case, the translog production variable
k is positive and significant to growth at the 1% level across all seven sets of estimations. The estimated results for
k are in line with the production theory and support previous studies that highlight the importance of capital and labour in promoting per capita GDP (Khandker
2016). In fact, Khandker (
2016) emphasise that physical capital, labour and technology are more significant in explaining per capita differences in economic growth across countries, even if an economy does not increase trade or liberalise its economy. This is reflected in the estimated findings, as the coefficients of
k are large and contributes to more than 55% of real GDP per labour differences across the seven sets of regressions.

However, when examining the time trend
t, which reflects technological change over the sample period, it is only positive and significant at the 15% level in four of the specifications. This suggests that technological change is not a strong driver of real GDP per labour growth in the ASEAN economies. This is interesting as the findings echo the criticisms of previous studies that suggest that the ASEAN economies have grown through capital intensive growth (Krugman
1994). The ASEAN economies must focus on identifying policies that can encourage technological progress, such as developing the human capital stock of an economy or implementing policies that promote innovative activities. These ultimately lead to technological change and sustainable long-run growth. Meanwhile, the estimated results provide some evidence of a convergence effect as it can be observed that the lagged real GDP per labour,
\( y_{i, t - 1} \), is consistently positive and significant across the seven sets of regressions. This suggests that the relatively poorer ASEAN economies are catching up to its wealthier counterparts and support the growth theory of convergence due to diminishing returns (Solow
1956). However, it highlights a slowdown in future growth may be expected, unless technological progress is increased through traditional policy prescriptions of improvements in human capital formation.
Focusing on financial development, the financial institutions and market variables provide interesting results. Financial institutions, fi, are consistently positive and significant to real GDP per labour in Sets (1), (2), (5) and (7). More interestingly, in Set (2), both fi and fi
2 are positive and significant, which suggests that financial institutions have a linear relationship to economic growth. This differs from recent studies that show financial development to be nonlinear and exhibit a
U-shaped curve on economic growth (Breitenlechner et al.
2015; Rousseau and Wachtel
2011). The linear relationship between financial institutions and growth in the ASEAN economies highlights the importance of banking sector in the region and suggests the effectiveness of the current policies implemented in the region (Almekinders et al.
2015). Many previous studies that suggest the nonlinear relationship between finance and growth can be attributed to excessive financialisation and liberalisation in financial markets (Gaffeo and Garalova
2014). Unsurprisingly, the estimated results show that financial markets and its squared term, fm and fm
2, are insignificant to growth in Sets (3) and (4).
Meanwhile, the rule of law, law, is consistently significant and positive to economic growth across all the seven sets of regressions. The rule of law is positive and significant to economic growth, which is expected as the ASEAN economies continue to develop as an institutionally sound region. The estimated results support previous studies that emphasise the role of legal institutions in the economy (Haggard and Tiede
2011; La Porta et al.
1998). More interestingly, the positive and significant effect of the rule of law may provide reasons for the differences in the effectiveness of financial structures. Aluko and Azeez (
2018) find that legal institutions help explain cross-country differences in stock market development. As a result, the rule of law and overall financial development can be complementary and enhance the quality of contract enforcement and the protection of investors. The rule of law has been a fundamental feature of the ASEAN organisation where member states are committed to develop strong legal institutions to promote regional peace and stability (ASEAN Secretariat
2008). As the estimated results find that the rule of law is positive and significant to economic growth, the ASEAN economies should continue to develop and observe strong governance of legal frameworks and regulation. This can potentially have spillover effects into other sectors, such as the financial markets and institutions in the region which can encourage the efficient allocation of resources for economic growth.
The interaction effect between financial markets with the rule of law, (fm × law), is positive and significant in Set (6), and the interaction effect between financial institutions with the rule of law, (fi × law), is also positive and significant in Set (7). The financial markets variable is insignificant in Sets (3) and (4), yet becomes significant and positive in Sets (6) and (7) when it interacts with the rule of law. This supports previous studies that emphasise the growing importance of financial markets, especially when an economy develops sound institutions (Hondroyiannis et al.
2005). Yet the insignificant results also provide an important implication, as it highlights the issue that financial markets across the ASEAN economies still remain fragmented and financial integration efforts are lagging behind when compared to financial institutions (Rillo
2018). Across the ASEAN economies, most of the region have underdeveloped financial markets with the exception of Singapore and as a result, the effects of financial markets may be insignificant as capital markets still remain fragmented, limiting the quality of financial intermediation. The ASEAN economies must continue to integrate its capital markets to facilitate further intra-regional investment flows among the ASEAN economies which can lead to further growth in the region.
Overall, the estimated results present an interesting scenario for the relationship between finance and growth in the ASEAN economies. On the one hand, the estimated results provide support for the role of finance, as the estimated results show that financial institutions are positive and significant to economic growth. This supports previous and recent empirical work that emphasises the role of financial development on economic growth (Ho and Iyke
2018; Sharma and Bardhan
2017). The positive relationship reaffirms the importance of financial development in spurring economic growth for the ASEAN economies despite suffering from a financial crisis during 1997. The positive significance of financial institutions in the region has coincided with the strong commitment of the ASEAN member states in developing a more integrated economic community with strong financial integration efforts (Almekinders et al.
2015). An example of integration efforts on financial institutions across the region is the creation of the Qualified ASEAN Banks which follows the European passporting approach for banks.
On the other hand, the estimated results find that the effects of financial markets to be insignificant to economic growth, thus, supporting the literature that postulates the weakening effects of finance on growth. There are empirical studies that find the effects of finance on economic growth to be insignificant or even negative in some cases (Beck et al.
2014; Rousseau and Wachtel
2011). This supports recent research that finds banking sector depth to be positive to economic growth in the ASEAN economies (Pradhan et al.
2017). In the case of the ASEAN economies, the insignificant effects of financial markets can be explained by the more rapid development of the financial institutions sector compared to financial markets. Previous financial development and integration policies in the ASEAN region focused on stability as opposed to focusing on growth (Almekinders et al.
2015). As a result, this has led to a fragmented financial market that is insignificant to growth. The findings suggest that policymakers should continue to strengthen the financial institution sector and implement policies to further integrate the financial markets sector across the region to achieve growth and prosperity through deeper financial linkages.
Finally, the estimated results of the control variables provide expected signs and significance. Human capital is significant and positive to economic growth, which is consistent with endogenous growth theories (Barro
1991; Mankiw et al.
1992). This is interesting as the ASEAN economies are diverse in its labour workforce in terms of languages spoken across the region especially when considering the movement of workers. The ASEAN economies encompass over 1000 different dialects with individual member states having more than one official language that includes English, Filipino, Indonesian, Khmer, Lao, Malay, Putonghua, Burmese, Spanish, Tamil, Thai and Vietnamese. Some studies find that human capital can be insignificant to growth when foreign language proficiency is not taken into account (Neycheva
2013). However, the ASEAN economies still practice English as an official language and most tertiary education systems in the region are conducted in the English language (ASEAN Secretariat
2018). Furthermore, many previous studies suggest that human capital is essential in enhancing the productivity of an economy and promotes technological progress that can spill over to other sectors in the economy (Oyinlola and Adedeji
2019; Zhou
2018). Focusing on the coefficients of hc, it can be observed that human capital accounts for over 20% of real GDP per labour growth across the sets of regressions. Thus, policymakers in the ASEAN economies should continue to implement policies that promote human capital development to increase economic growth.
Meanwhile, the estimated results show that openness to trade is positive and significant to economic growth. This supports many previous and recent studies that examine the effects of trade on economic growth (Anwar and Sun
2016; Darku and Yeboah
2018; Kheng et al.
2017). Traditionally, the ASEAN economies have relied on an export-oriented strategy for economic growth and as such, should continue to support trade liberalisation policies (Lee and Tan
2006). Openness to trade can further increase growth as it encourages foreign direct investments that can lead to spillover effects on the real economy, while reducing poverty through technology transfer and capital investments (Fowowe and Shuaibu
2014; Jiang
2012). Policymakers in the ASEAN economies should continue to identify and implement policies to encourage further intra-regional trade agreements which will have positive spillover effects on growth. Finally, population density, pop, presents mixed findings as it is insignificant in some of the specifications. In theory, the effects of population on economic growth are complex, as on the one hand, excessive population growth can be detrimental as it leads to an increase in consumption which lower investments in capital formation (Coale and Hoover
1958). Meanwhile, other economies, such as Singapore, suffer from a drop in fertility which reduces the amount of active labourer to people resulting in lower growth (Bloom and Williamson
1998). In the case of the ASEAN economies, this may be insignificant due to the diverse population growth of the individual member states.
There is vast empirical evidence that supports the role of finance and institutions in spurring economic growth. However, in recent years there is a body of literature that suggests a weakening relationship between financial development and economic growth, due to excessive financial liberalisation alongside the absence of strong institutional. The ASEAN economies have grown considerably since its inception in 1967 and have the potential for further economic growth. Despite experiencing the brunt of the Asian Financial Crisis, the region has recovered and has continued to grow. The ASEAN economies continue to integrate over the last two decades, implementing policies to liberalise trade, encourage cross-border banking and promote financial linkages. Previous empirical studies examining the ASEAN economies suggest that trade and export-oriented strategies play an essential role in the region’s growth. Although trade can promote economic growth through technological spillovers and capital investments, it can potentially be unsustainable in the long-run as the transfer of technology is disembodied and these investments will converge to its steady states. As a result, policymakers have begun to implement initiatives to develop the region through the ASEAN Economic Community Blueprint that involves regional efforts to advance financial development and integration alongside the development of sound institutions.
This study examines the role of financial structures and institutional development on economic growth in the ASEAN economies from 1995 to 2017 using a dynamic panel estimator. This study differs from previous examinations between finance and growth as it employs financial development indices proposed by Svirydzenka (
2016), which distinguishes financial institutions and markets while considering the accessibility, efficiency and depth of the respective financial structure. The use of the financial development indices differs from many previous studies that examine the effects of bank-based and market-based financial systems on economic growth, which usually focuses on specific characteristics of the financial structure such as banking-depth. As a result, this study provides new evidence on the role of financial structures in economic growth using financial development variables that provides a more complete measure.
In general, the estimated results show that financial and institutional development has a positive and significant impact on economic growth, supporting previous studies in the literature. However, the estimated results show that financial institutions are positive and significant to economic growth, while financial markets are insignificant. On the one hand, these findings support the view that postulates the weakening effects of finance on growth (Nain and Kamaiah
2014; Rousseau and Wachtel
2011). Yet the insignificance of financial markets on growth can be explained by previous studies, which find financial markets to be weaker and negative in the short-run (Gaffeo and Garalova
2014). In this case, stock market development is lagging behind in the ASEAN economies as financial institutions are still dominant in the region.
On the other hand, the significant effects of financial institutions suggest that further financial development and integration in the ASEAN economy is essential in order to promote economic growth (Dutta and Mukherjee
2018). Additionally, the study finds the rule of law to be positive and significant towards economic growth which is expected and supports many previous empirical works (La Porta et al.
2000). More interestingly, the rule of law is complementary to financial development as the interaction terms of financial institutions and markets with the rule of law is significant and positive to economic growth. This supports previous empirical studies that highlight the complementary role of finance and institutions on economic growth (Aluko and Azeez
2018; Pattanaik and Nayak
2014).
There are a number of policy implications for the study. Policymakers in the region should continue to further develop and integrate financial markets within the region, which can potentially spur economic growth in the ASEAN economies. Currently, the development of financial markets in the ASEAN economies is lagging behind when compared with financial institutions. As a result, policymakers should continue to advance the sector to ensure that financial markets are further integrated between the ASEAN economies while advancing efforts on developing capital markets that will connect the region with the world. This is important as the financial markets in the region are underdeveloped with the exception of Singapore. Thus, stronger integration in the region will encourage the free flow of capital between the member states and contribute to the goal of achieving an ASEAN Economic Community.
Furthermore, although financial institutions contribute to growth in the region, policymakers should identify an optimal level of financing and establish supervisory institutions that can monitor financial institutions across the region. This is important particularly with the implementation of the Qualified ASEAN Banks, which can dramatically increase financial development in the region. Financial liberalisation policies such as these can potentially lead to excessive financialisation particularly when economies lack institutional development. In general, the ASEAN economies have benefitted from finance and institutional development and have the potential to further increase growth. As such, the financial integration policies that ASEAN policymakers have introduced should continue as it has the potential to increase growth while considering further financial sector and institutional reforms.
There are a number of directions for future work. Although the econometric methodology employed in this study is sound, policymakers may be interested in the effects of financial and institutional development of the individual member’s states. This is of interest as the ASEAN economies are diverse in its economic development. For example, Singapore has a mature financial market, while the other ASEAN economies lag behind in development. Meanwhile, Cambodia, Lao PDR, Myanmar and Viet Nam, all lag behind in terms of overall financial and institutional development. Employing econometric strategies such as time-series methodology can provide further inferences on the effect of finance and institutions on the individual ASEAN economies.
