In this paper we investigate a `global' production function for agriculture, using FAO data for 128 countries from 1961-2002. Our review of the empirical literature in this field highlights that existing cross-country studies largely neglect variable time-series properties, parameter...

Since the seminal contribution of Gregory Mankiw, David Romer and David Weil (1992), the growth empirics literature has used increasingly sophisticated methods to select relevant growth determinants in estimating cross-section growth regressions. The vast majority of empirical approaches however...

In this paper we ask how technological differences in manufacturing production across countries can best be modeled when using a standard production function approach. We emphasise the importance of allowing for differences in the impact of observables and unobservables across countries, as well...

In this paper we ask how technological differences in manufacturing across countries can best be modeled when using a standard production function approach. We show that it is important to allow for differences in technology as measured by differences in parameters. Of similar importance are...

In this paper, we use a three-period panel of Tanzanian households to explore the determinants of earnings and earnings growth from 2004 to 2006. In doing so, we draw particular attention to the role of education and to the importance of heterogeneity between more and less formal occupations....

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...

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 labour productivity differentials between manufacturing firms in Ghana and South Korea exceed those implied by macro analysis. Median value-added per employee is nearly 40 times higher in South Korea than Ghana. The most important single factor in explaining this difference is the Mincerian...
