Assessing the productivity gains from multinational production has been a vital topic of economic research. Positive aggregate productivity gains are often attributed to within-firm productivity improvement; however, an alternative, less emphasized explanation is between-firm selection and...

Given the decline in growth momentum in the manufacturing sector in many OECD countries, the role of knowledge-based capital has emerged as a key driver for sustained growth. While empirical studies on estimating knowledge spillovers have usually been undertaken at the country level, the...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

The news-shock literature interprets empirical news-shock identifications as signals about future productivity. Under this view, changes in productivity cause changes in expectations. I investigate an alternative interpretation whereby changes in expectations cause changes in productivity. I...

Do natural resources benefit producer economies, or is there a "Natural Resource Curse," perhaps as Dutch Disease crowds out manufacturing? We combine new data on oil and gas abundance with Census of Manufactures microdata to estimate how oil and gas booms have affected local economies in the...

Since the early 1990s, the human security movement has sought to expand the concept of security beyond the traditional military defense of national borders to focus on the intra-state security needs of populations at the individual level. Specific initiatives frequently address problems of...

Foreign aid’s effectiveness in promoting economic growth remains mired in controversy.We examine the impact of the volatility of aid on economic growth, controlling for the level of aid. A four-year panel analysis is conducted encompassing 155 countries over the period 1966-2001. We find that...

In this paper we employ techniques developed in spatial econometrics to analyse spatial patterns of technology diffusion, to detect clusters and to estimate theoretical models that incorporate space explicitly. These techniques correct for misspecifications resulting from the omission of spatial...

This paper analyses the effect of this measurement error on GDP regressions. There is a systematic...</p></a>

Evolutionary and environmental economics have a potentially close relationship. This paper reviews past and identifies potential applications of evolutionary concepts and methods to environmental economics. This covers a number of themes: resource use and ecosystem management; growth and...
