We develop a model of endogenous skill-biased technical change in developing countries.  The model reconciles wildly dispersed existing estimates of the elasticity of substitution between more and less educated workers.  It also produces an estimating equation for the elasticity, which allow...

This paper constructs country-level aggregates of trade facilitation measures from firm-level responses in the Enterprise Surveys and compares them with the Doing Business indicators, the Logistics Performance Index and the Enabling Trade Index.  Correlations between the data sources are low...

Do better trade logistics reduce trade costs, raising a country's exports?  Yes, but the magnitude of the effect depends on country size.  Applying a new gravity model to a comprehensive logistics index, we find that an average-sized country would raise exports by about 46% after a...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selection into trade, while accommodating asymmetries in trade flows.  A new equation for the proportion of exporting firms takes a gravity form: the extensive margin is also affected by...

Commentators claim that a shortage of skills in South Africa is constraining output and that a rise in skill supply would benefit less skilled occupations. This assumes or implies skilled and unskilled labour are complements. Hicks Elasticities of Complementarity and elasticities of factor price...

An industry in decline provides an appropriate setting for the theory that mergers and acquisitions destroy implicit contracts and allow for the shedding of excess labour. We test this theory using provincial data from the South African gold mining industry, which has been in decline over the...

The first issue we study is the impact of transport costs on the volume and nature of international trade.  To what extent has the rise in international trade been driven by changes in transport costs?  Why is cross-country and cross-regional experience so different?  Transport costs also...

While intermediates comprise the majority of total goods trade in the European Union (EU), their share of total trade has remained flat since 1996. This implies that EU enlargement has had a limited effect on the size of Factory Europe. However, enlargement coincides with an increase in Factory...

This paper characterizes the trade performance of the Middle East and North Africa (MENA) over the past 15 years. Cross-section results show that MENA's exports to the outside world were only one third of their potential in recent years, after controlling for the standard determinants of trade....

This paper draws on existing empirical literature and an original theoretical model to argue that globalization and skill supply affect the extent to which technology adoption in developing countries favors skilled workers. Developing countries are experiencing technical change that is...
