Efficiency wage theory predicts that the wage per unit of effort will be lower in intensively monitored sectors. This wage differential will increase in effort. Using employer-employee matched data from Ghana we provide evidence supporting this hypothesis

We study how the import of older and more polluting technologies alters the relationship between output and environmental quality in developing countries within a vintage capital framework. Our results show that old technologies prolong the period until which pollution may eventually decrease...

This paper compares the performance of purely domestic plants, domestic exporters and domestic multinationals. For our empirical analysis we utilise a non-parametric approach based on the principle of first order stochastic dominance. Comparing the cumulative distributions of the measures of...

Crop biodiversity has the potential to enhance resistance to strains due to biotic and abiotic factors and to improve crop production and farm revenues. To investigate the effect of crop biodiversity on crop productivity, we build a probabilistic model based on ecological mechanisms to describe...
