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 Jarociński (2010) have questioned the approach on theoretical and empirical grounds. They argue that a standard...

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...

It is sometimes argued that foreign aid leads to a virtuous circle in which growth becomes self-reinforcing. We study two versions of this argument, using a modified neoclassical growth model in which the effects of parameter changes and capital accumulation are amplified. Simulations are used...

The economic boom of the USA in the 1990s was remarkable in its duration, the sustained rise in equipment investment, the reduced volatility of productivity growth, and continued uncertainty about the trend growth rate. In this paper we link these phenomena using an extension of the classic...

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...

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...

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 reduction in output...
