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...

Since the early 1990s, there has been a renaissance in the study of regional growth, spurred by new models, methods and data. We survey a range of modelling traditions, and some formal approaches to the ’hard problem’ of regional economics, namely the joint consideration of agglomeration and...

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,...

This paper introduces a framework for studying the optimal dynamic allocation of foreign aid among multiple recipients. We pose the problem as one of weighted global welfare maximization. A donor in the North chooses an optimal path for international transfers, anticipating that consumption and...

The issue of model uncertainty is central to the empirical study of economic growth. Many recent papers use Bayesian Model Averaging to address model uncertainty, but Ciccone and Jarocinski (2010) have questioned the approach on theoretical and empirical grounds. They argue that a standard...

This paper examines the structural determinants of output volatility in developing countries, and especially the roles of geography and institutions. We investigate the volatility effects of market access, climate variability, the geographic predisposition to trade, and various measures of...

The remarkable economic success of the United States in the 1990s led many observers to talk about a ‘New Economy’. This Paper provides an overview of the main issues, including faster productivity growth, the stability of inflation despite very low unemployment, the greater overall economic...

Several recent papers have argued that trade and financial development may be linked, either for political economy reasons, or because foreign competition and exposure to shocks lead to changes in the demand for external finance. In this paper we use the cross-country and time-series variation...

We examine the view that high-quality macroeconomic policy is a necessary, but not sufficient, condition for economic growth. We first construct a new index of the quality of macroeconomic policy. We then directly compare growth rate distributions across countries with good and bad policies; use...

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