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

This paper demonstrates some techniques for testing the robustness of cross-section and panel data regressions, and applies them to the influential augmented Solow growth model. The paper focuses on robust estimation and analysis of sensitivity to measurement error. In particular, it is shown...

Who benefits from economic growth? This paper analyses the distributional impact of different types of growth within a two-sector model. The paper first presents necessary and sufficient conditions for unambiguous changes in wage inequality in a dual economy, based on analysis of the entire...

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...

Standard macroeconomic models suggest that the ‘great ratios’ of consumptionto output and investment to output should be stable functions of structural parameters. We examine whether the ratios are stationary for the US and UK, allowing for structural breaks that could reflect timevarying...

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,...

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