This paper addresses the question of whether a conventional approach to cointegration is applicaple to the case where changes are allowed in the parameters for the short term dynamics. We reparametrise a vector autoregressive model such that the short-run parameters exhibiting changes at known...

The welfare effects of third-degree price discrimination are known to be negative when demand functions are linear, marginal cost is constant and all markets are served. This paper shows that discrimination lowers welfare for a more general class of demand functions. Demand varies across markets...

We present evidence that an increase in investment as a share of GDP predicts a higher growth rate of output per worker, not only temporarily, but also in the steady state. These results are found using pooled annual data for a large panel of countries, using pooled data for non-overlapping...

This paper aims to deepen our understanding of the determinants of income inequality in Uganda. Over the past 10 years, Uganda experienced gradual and sustained economic growth and poverty reduction. The benefits of growth, however, are not being distributed equally. The major contributions of...

We explore the role of reciprocity in wage determination by combining experimental and survey data. The experiment is similar to Berg, Dickhaut and McCabe`s (1995) and is conducted with Ghanaian manufacturing workers. The survey relates to the same sample workers and the firms within which they...

Opportunist land encroachment, resulting from costly and incomplete enforcement of common land boundaries, is a problem in many less-developed countries. A multi-period model of such encroachment is presented in this paper. The model accounts explicitly for the cumulative effects of...

A new game theoretic analysis of finite horizon, complete information bargaining is advanced. The extensive form reflects an attempt to model unstructured negotiations, in which the negotiants can gain no artificial advantage from the details of the bargaining protocol. Conditions are identified...

Boschen and Weise (Journal of Money, Credit and Banking, 2003) model the probability of a large upturn in inflation. We extend their work to show that openness to trade exerts a negative e¤ect on the probability of such an event.

This paper studies the ethical underpinnings of two social criteria which are prominent in the literature dealing with the problem of evaluating allocations of several consumption goods in a population with heterogeneous preferences. The Pazner-Schmeidler criterion (Pazner-Schmeidler [22]) and...

It has been argued that the use of personal networks in the hiring process has a positive influence on the wages of referred individuals. However, the value of recommendations to the employer varies according to the type of vacancy to be filled and the provider of information on job applicants....
