We propose a new method to estimate and isolate the localization of knowledge spillovers due physical presence person, using after-application but pre-grant deaths differently located coinventors same patent. The approach estimates differences in local citations between deceased still-living inventors at increasingly distant radii. Patents receive 26 percent fewer from within radius 20 miles ar...

We examine how the adoption of information communication technology affects bilateral trade. The context is a public program in Norway that rolled out broadband access points leading to plausibly exogenous variation availability and by firms. find makes trade patterns more sensitive distance economic size. These results are consistent with model variable elasticity demand. predicts lowers frict...

Can targeting information to network-central farmers induce more adoption of a new agricultural technology? By combining social network data and field experiment in 200 villages Malawi, we find that central is important spur the diffusion process. We also provide evidence one explanation for why centrality matters: process governed by complex contagion. Our results are consistent with model whi...

When we allow capital depreciation to be endogenous, the acceleration of investment-specific technological progress can distort the measurement of the aggregate capital stock. Our quantitative exercise shows that this effect may cause a substantial bias in the measurement of total factor productivity and can account for a large portion of the observed productivity slowdown since the 1970s. 2006...

We use time series techniques to estimate the importance of four main explanations for decline US labor income share: rising firm markups, falling bargaining power workers, higher investment-specific technology growth, and more automated production processes. Identification is achieved with restrictions derived from a stylized model structural change. Our results point automation as driver shar...

Improving “ last-mile” public service delivery is a recurring challenge in developing countries. Could the widespread adoption of mobile phones provide scalable, cost-effective means for improvement? We use large-scale experiment to evaluate impact phone-based monitoring on program that transferred nearly billion dollars 5.7 million Indian farmers. In randomly selected jurisdictions, officials ...

This paper presents an evolutionary growth theory that captures the interplay between the evolution of mankind and economic growth since the emergence of the human species. This uni"ed theory encompasses the observed evolution of population, technology and income per capita in the long transition from an epoch of Malthusian stagnation to sustained economic growth. 2001 Elsevier Science B.V.
