摘要：When human capital accumulation generates pecuniary externalities across professions, and capital markets are imperfect, persistent inequality in utility and consumption is inevitable in any steady state. This is true irrespective of the degree of divisibility in investments. However, divisibility (or fineness of occupational structure) has implications for both the multiplicity and Pareto-efficiency of steady states. Indivisibilities generate a continuum of inefficient and efficient steady st...

摘要：This paper examines the profitability of three types of integration in a cooperative game solved by a random-order value (e.g. the Shapley value). Collusion between players i and j is a contract merging their resources in the hands of one of them, say i. This contract can be represented as a combination of exclusion, which lets i exclude j's resource but not use it himself, and inclusion, which lets i use j's resource but not exclude j from it. This representation yields a third-difference con...

摘要：We add to the methods for conditioning out serially correlated unobserved shocks to the production technology. We build on ideas first developed in Olley and Pakes (1996). They show how to use investment to control for correlation between input levels and the unobserved firm-specific productivity process. We show that intermediate inputs (those inputs which are typically subtracted out in a value-added production function) can also solve this simultaneity problem. We discuss some theoretical b...

摘要：This paper develops a model to analyse how skill premia differ over time and across countries, and uses this model to study the impact of international trade on wage inequality. Skill premia are determined by technology, the relative supply of skills, and trade. Technology is itself endogenous, and responds to profit incentives. An increase in the relative supply of skills, holding technology constant, reduces the skill premium. But an increase in the supply of skills over time also induces a ...
