In many growth models, economic growth arises from people creating ideas, and the long-run growth rate is the product of two terms: the effective number of researchers and their research productivity. We present a wide range of evidence from various industries, products, and firms showing that...

Two recent meta-analyses use variants of the Baily, Hulten, and Campbell (1992) (BHC) decompositions to ask whether recent robust growth in Aggregate Labor Productivity (ALP) across twenty-five countries is due to lower barriers to input reallocation. They find weak gains from measured...

This paper examines the robustness of explanatory variables in cross-country economic growth regressions. It employs a novel approach, Bayesian Averaging of Classical Estimates (BACE), which constructs estimates as a weighted average of OLS estimates for every possible combination of included...

Externalities play a central role in most theories of economic growth. We argue that international externalities, in particular, are essential for explaining a number of empirical regularities about growth and development. Foremost among these is that many countries appear to share a common long...

This paper uses new data and new econometric techniques to investigate the impact of international financial integration on economic growth and also to assess whether this relationship depends on the level of economic development, financial development, legal system development, government...

Macroeconomists acknowledge the contribution of human capital to economic growth, but their empirical studies define human capital solely in terms of schooling. In this paper, we extend production function models of economic growth to account for two additional variables that microeconomists...

This paper presents an endogenous growth model of an open economy in which the growth rate of income is higher if foreign capital goods are used relatively more than domestic capital goods for the production of capital stock. Empirical results, using cross country data for the period 1960-85,...

We reexamine several bodies of data on the growth of output, labor, and capital, within the context of a model that admits the possibility of an externality to the capital input. The model is an augmented version of Paul Romer's (1987) reformulation of the Solow model. Unlike Romer, however, we...
