What is the role of transport improvements in globalization? We argue that the nineteenth century is the ideal testing ground for this question: freight rates fell on average by 50% while global trade increased 400% from 1870 to 1913. We estimate the first indices of bilateral freight rates for...

Recent medical research shows that health is highly influential for learning and the ability to think laterally; however, past economic studies have failed to empirically examine the influence of health on learning, schooling, and ideas production; the main drivers of growth in endogenous growth...

Global climate change mitigation will require the development and diffusion of a large number and variety of new technologies. How will patent protection affect this process? In this paper we first review the evidence on the role of patents for innovation and international technology transfer in...

This paper uses international trade data to examine the effects of climate shocks on economic activity. We examine panel models relating the annual growth rate of a country's exports in a particular product category to the country's weather in that year. We find that a poor country being 1...

Reducing emissions of the greenhouse gases that cause climate change will require dramatic changes in the way that energy is produced and consumed. The cost of technological changes such as alternative energy sources and improved energy efficiency will play a large role in determining the...

Large population / rapidly growing economies such as China and India have argued that in the upcoming UNFCCC negotiations in Copenhagen, any emission reduction targets they take on should be based on their intensity of emissions (emissions/$GDP) on a target date not the level of emissions. They...

In the paper we discuss China's participation in both the 2009 Copenhagen negotiations on a post-Kyoto global climate change regime currently under way and out beyond Copenhagen in further negotiations likely to follow. China is now both the largest and most rapidly growing carbon emitter, and...

What do we know about the relationship between innovation and productivity among firms? The workhorse model of this relationship is presented and the implications of analysis using this model and the usually available data on product and process innovation are derived. The recent empirical...

Entrepreneurship is thought to be a key driver of economic growth. While there are myriad forms of entrepreneurship, ranging from self-employment to small and medium size enterprises to technology- and innovation-driven startups, recent research provides evidence that the relationship between...
