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 appendix provides more details on how we calibrate the model, including parameter choices. Our solution procedure is to reduce each model to a set of nonlinear equations and then solve them numerically to obtain the unconstrained parameters and outcomes at the baseline equilibrium. We then...

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...

This paper shows how to calibrate a two-sector general equilibrium model of production using a small number of parameter assumptions and readily available data. The framework is then used to analyze the costs of labor market dualism. The paper quantiÞes the effects of rural-urban wage...

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...

This paper argues that dual economy models deserve a central place in the analysis of growth in developing countries. The paper shows how these models can be used to analyze the output losses associated with factor mis-allocation, aggregate growth in the presence of factor market distortions,...

This paper presents necessary and sufficient conditions for unambiguous changes in wage inequality in a dual economy, based on analysis of the entire Lorenz curve. These conditions are then used to analyze the distributional consequences of various types of economic growth. In particular, it is...

This paper highlights a problem in using the first-difference GMM panel data estimator cross-country growth regressions. When the time series are persistent, the first-differenced GMM estimator can be poorly behaved, since lagged levels of the series provide only weak instruments for subsequent...

This paper examines the adequacy of the augmented Solow model for explaining international variation in the standard of living and growth rates. Robust estimation and measurement error diagnostics are used to assess the model in a variety of dimensions. The main findings are that the speed of...
