We describe how managers can entrench themselves by making manager-specific investments that make it costly for shareholders to replace them. By making manager-specific investments, managers can reduce the probability of being replaced extract higher wages and larger perquisites from shareholders, and obtain more latitude in determining corporate strategy. Our model of entrenchment has empirical implications that are consistent with the evidence on managerial behavior.

This paper explores Rosenstein-Rodan's idea that simultaneous industrialization of many sectors of the economy can be profitable for them all even when no sector can break even industrializing alone. We analyze this idea in the context of an imperfectly competitive economy with aggregate demand spillovers and interpret the big push into industrialization as a move from a bad to a good equilibrium. We present three mechanisms for generating a big push and discuss their relevance for less developed countries.

Recent empirical research has identified a significant amount of volatility in stock prices that cannot easily be explained by changes in fundamentals; one interpretation is that asset prices respond not only to news but also to irrational “noise trading.” We assess the welfare effects and incidence of such noice trading using an overlapping‐generations model that gives investors short horizons. We find that the additional risk generated by noise trading can reduce the capital stock and consumption of the economy, and we show that part of that cost may be borne by rational investors. We conclude that the welfare costs of noise trading may be large if the magnitude of noise in aggregate stock prices is as large as suggested by some of the recent empirical litrature on the excess volatility of the market.

When world trade is costly, a country can profitably industrialize only if its domestic markets are large enough. In such a country, for increasing returns technologies to break even, sales must be high enough to cover fixed setup costs. We suggest two conditions conducive to industrialization. First, a leading sector, such as agriculture or exports, must grow and provide the source of autonomous demand for manufactures. Second, income generated by this leading sector must be broadly enough distributed that it materializes as demand for a broad range of domestic manufactures. These conditions have been important in several historical growth episodes.
