Nigeria's oil boom has not brought an end to perennial stagnation in the non-oil economy. Is this the unavoidable consequence of the resource boom or have misguided policies contributed? This paper indicates that the extreme volatility of expenditure rather than Dutch Disease effects are behind...

Using a standard complete specialization model of a small open economy within a rigorous intertemporal optimization framework and with contract-based wage rigidity, we show that permanent tariffs lead to a current account deterioration and a fall in employment, contradicting most of the...

We construct an open economy disequilibrium model to assess the welfare effects of aid in different macroeconomic regimes. Aid is shown to have different effects in different unemployment regimes because it increases the social costs of wage-price rigidities in the classical regime but decreases...

The analysis focuses on the government budget constraint and the resolution of inconsistent implications of different policy instruments under that constraint. We show how, under floating exchange rates, external shocks or internal structural reforms may cause jumps in inflation and the exchange...

We use a full general equilibrium 2-country, 2-period model with perfect capital markets, and intertemporal optimization and perfect foresight underlying private consumer behaviour in both countries to analyse the effects of pure fiscal policy. We demonstrate that higher government budget...

Africa, while a major aid recipient, has had disappointing export performance. This paper argues for a causal link: aid, by being partially spent on non-traded goods, leads to real appreciation and reduced export competitiveness. I demonstrate the importance of this effect by presenting...

At what speed should Mexican agriculture be incorporated into the North American Free Trade Agreement (FTA)? What policies should characterize the transition? We use Mexican agriculture as a case study to analyse the transition problems that arise in most major economic reforms. In particular,...

How fast should Mexican agriculture be incorporated into the North American Free Trade Agreement? The authors focus on the implications for policy design of the absence of efficient capital markets on the welfare costs of reforming gradually, on incentive problems created by trade adjustment...
