The publication of János Kornai’s memoirs, By Force of Thought, provides an excellent opportunity to remind ourselves of Kornai’s great contributions to economic research. This paper discusses both his basic research strategy and some of his main research results. Kornai has usually dealt...

The Industrial Institute of Economic and Social Research (IUI) was founded in 1939. In less than ten years, IUI grew from a small survey bureau to a leading research institute focused on microeconomic research relevant to industrial development. Based on a number of new commemorative essays and...

This paper addresses various attempts by so-called new Keynesians, writing mainly in the 1980s and 1990s, to strengthen the analytical basis, in particular the microeconomic foundations, of these assertions. What, exactly, have then the new Keynesians accomplished, and how should their...

Recent empirical evidence suggests that prices for some goods and services are higher in larger markets. This paper provides a demand-side explanation for this phenomenon when firms can choose how much to differentiate their products in a model of monopolistic competition with horizontal product...
