The debt crisis and IMF policy

The discussions anticipating the annual joint meeting of the IMF and the World Bank in Berlin this autumn have again drawn the increased attention of a broader public to the debt problems of the developing countries. Alternative groups are planning to hold an anti-congress, in which especially the role of the IMF and the World Bank in this connection are to be subjected to a critical examination. The following article describe the basic points of criticism.     

SAVING AND INVESTMENT: PARADIGMS, PUZZLES, POLICIES

The 1990s have seen a renewed interest in issues of capitalaccumulation and growth. New paradigms for saving, investment,and growth have been advanced to address theoretical and empiricalpuzzles and to guide the design of better policies. This paperprovides a policy-oriented review of recent theoretical andempirical work on the determinants of saving and investmentand on their links to growth. It takes stock of new findingsas well as still unresolved questions and gives particular attentionto empirical regularities and to the policy issues relevantto developing countries.      

A second look at the Maastricht Treaty

The Maastricht Treaty aims to define the path towards a single currency in the European Community by the end of the century. The following article analyzes the strategy laid down in the Treaty in the light of recent events, highlights its internal contradictions and the obstacles it is likely to meet, and assesses its chances of success.

Productivity gaps and capacity utilization in the manufacturing sectors of five OECD-countries, 1963–1982

The purpose of this paper is to apply some novel features in the theory of productivity indexes to the measurement of productivity gaps. It advances the proposition that one reason for the persistence of productivity gaps might be that the methodology of measuring gaps does not separate shifts of the production function due to intercountry efficiency from shifts due to intercountry differences in capacity utilization.In this paper we calculate productivity gaps for four OECD countries relative to the U.S., adjusted for cyclical variations in capacity utilization for the period 1963–1982. The theoretical foundation of our measurement is based on a variable cost function approach with short-run fixity of capital. Without adjusting for differences in capacity utilization within the countries, productivity gaps are a mixture of differences in productivity and in capacity utilization.The refereeing process of this paper was handled through C.

Relative Price Changes, Wages and Unemployment in a Specific Factors Model with Search Frictions

This paper analyzes the effects of changes in the relative product price on wages and unemployment of a small open economy in a specific factors model characterized by search frictions. It shows that unemployment and wages move in opposite directions, i.e., high unemployment is associated with low wages and low unemployment with high wages. The reason for the employment effect is found to be individual wage bargaining.     

Tenure security and land-related investment: Evidence from Ethiopia

We use a large data set from Ethiopia that differentiates tenure security and transferability to explore determinants of different types of land-related investment and its possible impact on productivity. While we find some support for endogeneity of investment in trees, this is not the case for terraces. Transfer rights are unambiguously investment-enhancing. The large productivity effect of terracing implies that, even where households undertake investments to increase their tenure security, the level of such investment may be below the social optimum. In Ethiopia, government action to increase tenure security and transferability of land rights can significantly enhance rural investment and productivity.     

Unequal factor prices and incomplete specialization in a Heckscher-Ohlin model of endogenous growth

Two-factors, two-goods Heckscher-Ohlin trade theory predicts that under certain circumstances factor prices equalize if countries are incompletely specialized. If at least one country is completely specialized no factor-price equalization obtains. Different factor rewards and free trade, however, are not automatically linked to complete specialization: in a Heckscher-Ohlin model of endogenous growth where the countries differ in their individual discount rates, a situation of incomplete specialization and different factor rewards will result.
