Examining the most heavily-cited publications in labor economics from the early 1990s, I show that few of over 3000 articles citing them directly replicates them. They are replicated more frequently using data from other time periods and economies, so that the validity of their central ideas has...

We present a simple framework for analyzing decline in union voice in the Anglo-American world and its replacement by non-union, often direct, forms of worker voice. We argue that it is a decline in the in-flow to unionisation among employers and workers, rather than an increase in the outflow...

We utilize the analytical construct of a stochastic supply function to provide an aggregate representation of a finite collection of standard deterministic supply functions. We introduce a consistency postulate for a stochastic supply function that may be satisfied even if no underlying...

We develop a theory of firm scope in which integrating two firms into one facilitates the allocation of resources, but leads to weaker incentives for effort, compared with non-integration. Our theory makes minimal assumptions about the underlying agency problem. Moreover, the benefits and costs...

The paper examines the determinants of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organization away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the existing literature on the...

Despite being a fixture of everyday life in the Arab world, wasta, which may be thought of as special influence by members of the same group or tribe, has received little attention from social scientists. Our casual empiricism suggests that wasta is an important determinant of how economic...

Employment contracts give a principal the authority to decide flexibly which task his agent should execute. However, there is a tradeoff, first pointed out by Simon (1951), between flexibility and employer moral hazard. An employment contract allows the principal to adjust the task quickly to...

Internal organization relies heavily on psychological consistency requirements. This thought has been emphasized in modern compensation theory, but has not been extended to organization theory. The perspective sheds new light on several topics in the theory of the firm, like the boundaries of...

This paper offers a rationale for limiting the delegation of (real) authority, which neither relies on insurance arguments nor depends on ownership structure. We analyse a repeated hidden action model in which the actions of a risk neutral agent determine his future outside option. Consequently,...
