This paper offers two innovations for empirical growth research. First, the paper discusses principal components augmented regressions to take into account all available information in well-behaved regressions. Second, the paper proposes a frequentist model averaging framework as an alternative...

If Janossy's theory should concisely be drafted, one might say that he had been researching the "real carrier of economic development" in a very original way and having formulated his theory in a specific language. He managed to identify the "carrier" of development focusing on the systematic...

Unskilled labor is the abundant resource in many developing countries, especially at an early stage of their development. Yet, even as at given technologies labor markets have not cleared, neo-classical economists have rejected the notion of an institutional or bargaining wage not based on...

This paper examines how changes in urban industrial network structures explain the growth rates of labor productivity in cities. I formulate a multi-sector general equilibrium model with input-output networks of firms within a city and trade across cities. A key input to this framework is an...

Why are skilled workers more mobile than average? What determines positive migration flows toward relatively poorer regions or states of a country? How can one explain the sharp decrease in the mobility rate observed within European countries notwithstanding the persistent regional disparities?...

This paper offers an explanation of the high mobility of skilled workers based on human capital complementarities. If the skill premium is increasing in the average level of human capital of a location, and there exist fixed migration costs, in equilibrium the more skilled the workers are, the...

Why are highly skilled workers more responsive than other workers to productivity differentials when taking migration decisions? Why do low-skilled workers abandon rich regions? This paper aims to answer these questions using skill complementarities and endogenous price differentials between...

The geography of innovation describes the importance of proximity and location to innovative activity. As part of what has been termed the new economic geography, this area of research is less than 20 years old, and is now developed sufficiently so that the discussion can be organized around...
