Most measures of vulnerability are a-theoretic and essentially static. In this paper we use a stochastic Ramsey model to find a household's optimal welfare and we measure vulnerability as the shortfall from the welfare attained if the household consumed permanently at the poverty line. The...

This paper uses survey data to investigate empirically the importance of corruption in determining firm performance in Africa. We allow for the possibility of perception bias on the part of the respondents and for corruption being endogenous. We find that corruption is linked to significant...

Recent reforms in most African economies of their trading and exchange rate regimes have eliminated much of the protection which previously limited competition. Despite these reforms, African manufacturing firms remain unsuccessful, particularly in international export markets. In this paper we...

The determination of the causal pattern among inflation, money growth, and exchange rate has important implications for policymakers regarding appropriate stabilization policies in developing economies. Using Congolese data where the pace of broad money growth and hyperinflation (23,760% annual...

During the nineties, Rwandan households had to cope with severe shocks of war and genocide. In addition, two major structural problems in Rwanda, land scarcity and declining soil fertility, remain unsolved. How do Rwandan households manage? This is an important question from a development...

This paper investigates the role of ethnicity and networks in domestic agricultural trade in Africa. Using a theoretical model of self- disciplining markets, we begin by demonstrating that statistical discrimination and networks can generate similar patterns of ethnic concentration. We then test...

Studies in the microeconometric literature increasingly utilize distance to or time to reach markets or social services as determinants of economic issues. These studies typically use self-reported measures from survey data, often characterized by non-classical measurement error. This paper is...

The paper uses the 1992 household survey for Bulgaria to show poor revenue performance of the income tax structure prevailing in 1992, which did not take into account the underlying distribution of income. The paper shows that Bulgaria can benefit from a much lower and simpler income tax rate...

The new business cycle three-dimensional model is formulated on the basis of new system approach known as the System Potential Method. Cyclical dynamics with catastrophe jumps (alike to Varian' model) and some stochastic properties is described. Properties of such cycles are similar to the...
