This paper summarizes and extends previous research that has shown evidence of a `curse of natural resourcesa } countries with great natural resource wealth tend nevertheless to grow more slowly than resource-poor countries. This result is not easily explained by other variables, or by alternative ways to measure resource abundance. This paper shows that there is little direct evidence that omi...

Mo-doped BiVO4 electrodes were prepared by an electrochemical route for use as photoanodes in a photoelectrochemical cell. The purpose of Mo-doping was to improve the electron transport properties, which in turn can increase the electron-hole separation yield. The poor electron-hole separation yield was known to be one of the main limiting factors for BiVO4-based photoanodes. The electrochemica...

The Serratia marcescens N28b wbbL gene has been shown to complement the rfb-50 mutation of Escherichia coli K-12 derivatives, and a wbbL mutant has been shown to be impaired in O4-antigen biosynthesis (X. Rubirés, F. Saigí, N. Piqué, N. Climent, S. Merino, S. Albertí, J. M. Tomás, and M. Regué, J. Bacteriol. 179:7581-7586, 1997). We analyzed a recombinant cosmid containing the wbbL gene by subc...

We investigate the speed at which clusters of invention for a technology migrate spatially following breakthrough inventions. We identify breakthrough inventions as the top one percent of US inventions for a technology during 1975-1984 in terms of subsequent citations. Patenting growth is signi…cantly higher in cities and technologies where breakthrough inventions occur after 1984 relative to p...

This paper is analyzes a neoclassical overlapping generations model. We discuss a two-sector economy with intermediate and final goods in the spirit of Romer (1990). Agents engage in one of two alternative occupations: either self–employment in the intermediate goods sector, which is characterized by monopolistic competition, or employment as an ordinary worker in this sector. Entrepreneurial p...

We contrast effects of taxing non-renewable resources with the effects of traditional capital taxes and investment subsidies in an endogenous growth model. In a simple framework we demonstrate that when non-renewable resources are a necessary input in the sector where growth is ultimately generated, interest income taxes and investment subsidies can no longer affect the long-run growth rate, wh...

Are market-based or bank-based financial systems better at financing the expansion of industries that depend heavily on external finance? Are marketor bank-based financial systems better at facilitating the formation of new firms? We find evidence for neither the market-based nor the bank-based hypothesis. We find overwhelming evidence that industries that are heavily dependent on external fina...

This paper uses a production function approach to put the recent contribution of the New Economy to US economic growth into perspective by undertaking an analysis of the sources of technical progress in the business sector over the post-war period. We model jointly a pair of factor demand equations derived consistently from an underlying CES production technology, and explicitly endogenise tech...

This paper aims to contribute to the new growth theory with a model in which the engine of growth is human capital growth. Building on Romer’s [1990] model, two new functions are introduced: (1) A speci...cation for the production of new designs that assumes no externalities and no inventions before time zero; and (2) A speci...cation for the accumulation of human capital technically similar to...

The mechanisms of growth out of backwardness are investigated in an intertemporal general equilibrium model for Thailand. Learning by exporting is assumed to be the main vehicle of international spillover. While the econometric literature discusses the causality between exports and productivity, we analyze the endogenous dynamic interaction and with long run growth effects of economic policy. T...
