The migration of young Chinese scientists to undertake graduate studies in U.S. universities is arguably one of the most important recent episodes of skilled migration. Using a new data set covering around 16,000 Ph.D. graduates in 161 U.S. chemistry departments, we show that Chinese students...

Empirically, a higher frequency of lightning strikes is associated with slower growth in labor productivity across the 48 contiguous U.S. states after 1990; before 1990, there is no correlation between growth and lightning. Other climate variables (e.g., temperature, rainfall, and tornadoes) do not...

I examine the effect of age-distribution of the society on economic growth through technological progress. I build a multisector economy model that involves population pyramid. I characterize the steady-state of the model for low and high population growth rate. Higher population growth rate...

The growing importance of innovation in economic growth has encouraged the development of innovation capabilities in East Asia, within which China, Japan, and Korea are most important in terms of technological capabilities. Using U.S. patent data, we examine how knowledge networks have developed...

This paper analyzes factors that shape the technological capabilities of individual U.S. states and European countries, which are arguably comparable policy units. The analysis demonstrates convergence in technological capabilities from 2000 to 2007. The results indicate that social...

This paper looks at the genesis of innovation in the United States from a territorial perspective. The analysis aims to disentangle the impact of local R&D expenditure from other contextual conditions supportive of the process of innovation. Particular emphasis is devoted to the role of...

European coal production underwent a period of dramatic increase from the early nineteenth century to 1913. A consensus exists, however, for a depiction of the coal industry as, to a high degree, technologically stagnant throughout the long nineteenth century. Macro-inventions, or general...

The slower productivity growth in Canada relative to that experienced in the United States in the second half of the 1990s has been a matter of great concern to Canadians, with a wide variety of explanations put forward to account for this development. A key issue is whether this slower...
