The competitive allocation of labor across different sectors of an economy may not be socially optimal when one sector uses foreign capital. We argue that a suitably designed government intervention is required to restrict the sectors to their optimal size and maximize national welfare. Such a...

Haavelmo's seminal 1943 paper is the first rigorous treatment of causality. In it, he distinguished the definition of causal parameters from their identification. He showed that causal parameters are de fined using hypothetical models that assign variation to some of the inputs determining...

International joint ventures (JV) are popular institutional forms chosen by the less developed countries (LDCs) to attract foreign Investments. In this paper we describe a set up where a multinational firm (MNF) decides on the volume of investment and the LDC gov-ernment offers a package...

We study the possibility of cartel formation among primary exporters who face an inelastic world demand for their exports. By constructing an appropriate infinitely repeated export game, we show that varying country sizes will pose difficulties in sustaining the collusive behaviour.

The concept of factor intensity has played a key role in the development of international trade theory. The factor proportions utilized in the production of commodities differ from activity to activity. Some commodities employ a higher ratio of capital to labor than do others, and the basic...

The parpose of this paper is to model and describe the consequences for labor markets in an underdeveloped economy of foreign Investment in an enclave sector.Foreign technology tends to expose some of the hidden talents in the local labor force.Replacement of foreign labor by domestic labor...

This paper builds up a two country model of trade and unemployment allowing for perfect mobility of capital across the borders. Capital moves from the north to the south, which suffers from unemployment. A few basic policies related to lowering of unemployment are discussed. In particular it is...

This paper considers the problem of making inferences about the effects of a program on multiple outcomes when the assignment of treatment status is imperfectly randomized. By imperfect randomization we mean that treatment status is reassigned after an initial randomization on the basis of...

This paper discusses and illustrates identification problems in personality psychology. The measures used by psychologists to infer traits are based on behaviors, broadly defined. These behaviors are produced from multiple traits interacting with incentives in situations. In general, measures...
