This paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis. Aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset...

The Ghana cocoa market has been extensively liberalised over the period since the mid 1980s. Three issues have been prominent in microeconomic research on the effects of liberalisation on agriculture. The first has been the size of any supply response, the second has been the effect on producers...

While it might be expected that schooling will depend positively on the economic returns to education (ER) in the local labor market, in fact there is theoretical ambiguity about the sign of the schooling-ER relationship when households are liquidity-constrained. Whether the relationship is...

This paper examines the trade and trade-induced welfare effects of high oil prices. Using a gravity model of trade we find that the distance elasticity of trade signif- icantly increases with the oil price. This suggests that high oil prices make trade less global. We estimate that an increase...

In a monetary policy model incorporating partial persistence in inflation it is shown that inflation bias is reduced and the response to shocks improved if the policy maker has a discount rate lower than its true social value. Thus a patient central banker is shown to be a third mechanism for...

A classroom model of global warming, fossil fuel depletion and the optimal carbon tax is formulated and calibrated. It features iso-elastic fossil fuel demand, stock-dependent fossil fuel extraction costs, an exogenous interest rate and no decay of the atmospheric stock of carbon. The optimal...

In our model, we treat a market game where traders are heterogeneous not only with respect to their rationality level but also with the formation of their subjective beliefs for the strategy of their opponents. Under these conditions, the market mechanism results a statistical equilibrium, where...

ABSTRACT: Real wages in Ghana have fallen substantially over the last twenty years. The question posed by this paper is whether this evidence for wage flexibility implies a competitive market clearing labour market. It is argued that it does not. There is sufficient flexibility in the production...

This paper gives a non-fixed point theoretic proof of equilibrium existence when the excess demand function of an exchange economy obeys the weak axiom. The proof is simple and geometrically intuitive, and it also permits a weakening of the continuity assumption on the excess demand function....

High-profile universities often face public criticism for undermining academic merit and promoting social elitism/engineering through their admissions-process. In this paper, we develop an empirical test for whether access to selective universities is meritocratic. We assume that students who...
