This paper examines the relationship between Schumpeterian patterns of innovation and the generation of breakthrough inventions. Our data source for breakthrough inventions is the “R&D 100 awards” competition organized each year by the magazine Research & Development. Since 1963, this magazine has been awarding this prize to 100 most technologically significant new products available for sale or licensing in the year preceding the judgment. We use USPTO patent data to measure the relevant dimensions of the technological regime prevailing in each sector and, on this basis, we provide a characterization of each sector in terms of the Schumpeter Mark I/Schumpeter Mark II archetypes. Our main finding is that breakthrough inventions are more likely to emerge in ‘turbulent’ Schumpeter Mark I type of contexts. 相似文献

This paper conducts an empirical analysis on the U.S. VCR market using a hedonic approach. The paper finds that quality-adjusted price indices decline at 11-12% per year, with a large annual drop of about 18% from 1982-85. Estimation and data analysis reveal interesting aspects of the evolution of quality and price in the VCR market. As a result of the exclusion of the VCR category until 1986, the paper estimates a bias of 2.4% per year in the CPI electronics subindex. 相似文献

This paper proposes and studies a tractable subset of Nash equilibria, belief-free review-strategy equilibria, in repeated games with private monitoring. The payoff set of this class of equilibria is characterized in the limit as the discount factor converges to one for games where players observe statistically independent signals. As an application, we develop a simple sufficient condition for the existence of asymptotically efficient equilibria, and establish a folk theorem for N-player prisoner?s dilemma. All these results are robust to a perturbation of the signal distribution, and hence remain true even under almost-independent monitoring. 相似文献

We examine the effects of free trade agreement (FTA) on tariffs and welfare in a three‐country model with vertical trade, where an FTA is formed between a country exporting a final good whose production involves using an intermediate good, and a country exporting the intermediate good in exchange for the final good. We demonstrate that the FTA reduces its member country's external tariff, whereas it raises the non‐member country's tariff. The non‐member country unambiguously becomes better off. In contrast, the FTA may or may not make its member countries better off. This implies that the formation of an FTA may not always be Pareto‐improving. 相似文献

This paper examines the diffusion process of Internet broadband access in Japan by modeling the household choice of access modes. Estimates reveal that the characteristics of users, rather than those of the access modes, play a significant role in demand substitution across the modes. Simulation exercises indicate that had optic fibers (fiber-to-the-home; FTTH) been made available to the whole country in 2005, only 10% of households would have switched to that mode. This result implies that once chosen, the household choice of access mode persists, and that indirect network effects are an important element in decisions to adopt the new technology of broadband. Finally, policy implications are discussed. 相似文献

By using both macro‐ and micro‐level data, this paper investigates how wages and prices evolved during Japan's lost two decades. We find that downward nominal wage rigidity was present in Japan until the late 1990s, but disappeared after 1998 as annual wages became downwardly flexible. Moreover, nominal wage flexibility may have contributed to Japan's relatively low unemployment rates. Although macro‐level movements in nominal wages and prices seemed to be synchronized, such synchronicity is not observed at the industry level. Therefore, wage deflation does not seem to be a primary factor of Japan's prolonged deflation. 相似文献

The welfare effect of a free trade agreement in the presence of foreign direct investment and rules of origin 下载免费PDF全文

This paper investigates the welfare effect of forming a free trade agreement (FTA). To receive tariff‐free treatment, firms must comply with the rules of origin (ROO). Outside firms could undertake either market‐oriented or export‐platform foreign direct investments (FDIs). ROO have the following effects: (i) An infeasible FTA may become feasible by deterring outside firms' FDIs, (ii) an FDI of a less efficient firm could replace that of an efficient firm, or (iii) FDIs made before the FTA is concluded might be eliminated. These potential effects complicate the welfare effect of the FTA and could decrease the consumer surplus. 相似文献

This study examines how information broadcasting through television (TV) media influences stock market activities. Consistent with the effect of TV information to attract investor attention, we find that increased information flow through TV is significantly associated with greater trading volume and larger price change. For information type, hard news from business-oriented programmes and earnings-related news strongly contributes to the attention effect, while the effect of soft news is weaker. Bid–ask spread widens for more TV information flows, suggesting that new information arrival in the market expands information asymmetry. Finally, the impact of TV is more influential for stocks with more individual shareholders than those with institutional shareholders. 相似文献

Using bank-level data in Asia, we examine the relationship between the effectiveness of monetary policy and the business diversification of banks. We find that bank diversification enhances the effect of monetary policy. 相似文献
