3. Impatience

This chapter delves into the economic principle of discounting, which involves comparing the value of money or resources at different points in time. It begins with a practical example of investing in a Certificate of Deposit (CD) to illustrate how future values are discounted to present terms. The text then explores the concept of impatience in economic decision-making, using the example of Mr. Kuchenfresser and his cake consumption to demonstrate how discounting affects consumption choices over time. The chapter provides a mathematical framework for understanding dynamic optimization, showing how discount rates influence the allocation of resources across different periods. It concludes with a visual representation of optimal consumption paths, highlighting how higher discount rates lead to a preference for earlier consumption. The chapter also discusses the implications of discounting for long-term financial planning and investment decisions.
