This paper develops empirical growth models suitable for dual economies, and studiesthe relationship between structural change and economic growth. Changes in the structureof employment will raise aggregate productivity when the marginal product of labourvaries across sectors. The models in the...

This paper examines whether growth regressions should incorporate dualism and structural change. If there is a differential across sectors in the marginal product of labour, changes in the structure of employment can raise aggregate total factor productivity. The paper develops empirical growth...

We introduce a new supply-push' instrument for foreign aid, to be used together with an instrumental variable estimator that filters out unobserved common factors. We use this instrument to study the effects of aid on macroeconomic ratios, and especially the ratios of consumption, investment,...

In middle-income countries, the informal sector often accounts for a substantial fraction of the urban labor force. We develop a general equilibrium model with matching frictions in the urban labor market, the possibility of self-employment in the informal sector, and scope for rural-urban...

Models of open economies with nominal rigidities are often thought to predict a correlation between openness to trade and the slope of the output-inflation trade-off, or Phillips curve. Using a variety of measures of the trade-off and a standard measure of openness, this paper argues that the...

The idea that income differences between rich and poor nations arise through multiple equilibria or 'poverty traps' is as intuitive as it is difficult to verify. In this paper, we explore the empirical relevance of such models. We calibrate a simple two sector model for 127 countries, and use...

We examine whether structural transformation leads to a Kuznets curve. We present a dynamic general equilibrium model with heterogeneous workers, occupational self-selection and selective migration, and calibrate the model to survey data for Malawi. We show that structural transformation raises...

For many developing countries, international transfers are now a significant source of income. These transfers include official development aid, private charitable donations, and personal remittances. This paper uses dynamic one-sector and multi-sector models to isolate conditions under which...
