MAIDS Under Additive Preferences: Some Early Estimates

It gives us pleasure to contribute to this volume in honour of Henri Theil, who was very influential at a critical stage in the career of one of us (Powell). During 1964 Theil gave a series of lectures on demand analysis at the University of Chicago during Powell’s post-doctoral year there; much of this material subsequently appeared in Economicsand Information Theory (1967) and in later works. Powell’s subsequent research in applied demand analysis owes a considerable intellectual debt to Theil. This association (again centred on consumer demand) was to be renewed more than two decades later when Theil invited Powell to spend some months with him during the first half of 1987 at the University of Florida as the McKethan-Matherly Senior Research Fellow.
