Should agriculture or non-agriculture be a priority for development? We revisit this longstanding and intractable question using a two-sector, three-factor dynamic model with an asymptotic balanced growth path. The model allows a forward-looking assessment of development priorities based on...

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the quantitative implications of a simple two-sector general equilibrium model that gives rise to multiplicity, and calibrate the model for 127 countries. Under the...

The conventional wisdom is that postwar economic growth has been unpredictable. In the 1960s few observers accurately forecast which countries would grow quickly. In this paper we show that indexes of social development constructed in the early 1960s have considerable predictive power. These...

This paper constructs simple models in which industrialization is driven by human capital accumulation. Industrialization can explain the robust correlation between equipment investment and growth in developing countries. We show that government intervention is justified within our stylized...

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...
