We present a model in which purely monetary inflation systematically affects efficiency, welfare, and relative prices. The model focuses on the microeconomics of trade in search markets under inflation. Inflation, by increasing the cost of holding money, undermines the market's ability to sustain long‐term customer relationships. Because those relationships generate the most efficient transactions patterns, overall welfare unambiguously declines. 相似文献

We develop a model of firm size, based on the hypothesis that consumers are “locked in,” because of search costs, with firms they have patronized in the past. As a consequence, older firms have a larger clientele and are able to extract higher profits. The equilibrium of this model yields: (i) A downward sloping density of firm sizes. (ii) Older firms are less likely to exit than younger firms. (iii) Larger firms spend more on R&D. 相似文献

We construct a simple model that tests for repressed inflation by estimating a true rate of inflation that explains behavior of observed money demand. We estimate the model using quarterly data for Czechoslovakia and Poland. Although our results should be viewed as preliminary, given the imperfect nature of our data, we do have strong evidence that, prior to 1991, there was considerable repressed inflation in Poland, while there was essentially no repressed inflation in Czechoslovakia.This paper was funded by a World Bank project on formerly planned economies. We would like to thank Jong-goo Park for suggesting the topic, and Fabrizio Coricelli and Adnan Mazarei for helpful discussions. The views expressed here are our own and do not necessarily reflect the opinions of the World Bank. 相似文献

Increasing returns and the new world of business 总被引:58,自引:0,他引:58
Arthur WB 《Harvard business review》1996,74(4):100-109
Our understanding of how markets and businesses operate was passed down to us more than a century ago by English economist Alfred Marshall. It is based on the assumption of diminishing returns: products or companies that get ahead in a market eventually run into limitations so that a predictable equilibrium of prices and market shares is reached. The theory was valid for the bulk-processing, smokestack economy of Marshall's day. But in this century, Western economies have gone from processing resources to processing information, from the application of raw energy to the application of ideas. The mechanisms that determine economic behavior have also shifted--from diminishing returns to increasing returns. Increasing returns are the tendency for that which is ahead to get further ahead and for that which is losing advantage to lose further advantage. If a product gets ahead, increasing returns can magnify the advantage, and the product can go on to lock in the market. Mechanisms of increasing returns exist alongside those of diminishing returns in all industries. But, in general, diminishing returns hold sway in the traditional, resource-processing industries. Increasing returns reign in the newer, knowledge-based industries. Modern economies have split into two interrelated worlds of business corresponding to the two types of returns. The two worlds have different economics. They differ in behavior, style, and culture. They call for different management techniques, strategies, and codes of government regulation. The author illuminates those differences by explaining how increasing returns operate in high tech and in service industries. He also offers advice to managers in knowledge-based markets. 相似文献

Willingness to take on risk is influenced by the presence of fair and unfair background risks for decision makers who are risk vulnerable as defined by Gollier and Pratt [1996], for these decision makers are more risk averse when they possess such an uninsurable background risk. We present an alternative derivation of the index of local vulnerability based on Diamond and Stiglitz [1974] compensated increases in risk, such that risk aversion increases with the introduction of any small fair background risk if and only if the index of local vulnerability is positive. We establish that the increase in risk aversion is greater for those who are more vulnerable as measured by the index of local vulnerability. 相似文献

We present three conditions for a demography-driven middle-income trap and show that many economies in East, South, and Southeast Asia satisfy all of them. The conditions involve (1) the support ratio of workers to consumers has an impact on economic growth, (2) economic development accompanies more investment in human capital and lower fertility due to the quantity–quality trade-off, and (3) a current low level of fertility corresponds to very low support ratios for keeping up with frontier economies in the long run. Panel analysis for 178 countries shows that (1) and (2) are satisfied for Asia with higher elasticity than others. As for (3), we set up a dynamic model for simulations, showing that approximately two-third of Asia’s developing countries have an unsustainable level of support ratios, implying possibility of a middle-income trap due to future demographic headwinds. 相似文献

Using technological capabilities as embodied in machinery, organization, processes and products, this study examines the links with host-site institutions and regional production linkages. The statistical results show no relationship between these variables. In-depth interviews complement the quantitative findings. Overall, the result shows that the government’s localization efforts failed because too many joint-venture assemblers were approved in the 1990s when the domestic market was small. The lack of economies of scale also affected the growth of national suppliers. Hence, national producers are confined to low value added segments and lack the quality to compete in export markets. 相似文献

ABSTRACT New information and communication technologies continue to spread rapidly into the Asian marketplace, which has led to new patterns of leisure consumption, one of the most popular being digital gaming. However, in Vietnam there is limited research on gaming as a leisure activity. The purpose of this study is to explore the phenomenon of digital gaming in Vietnam to better understand how it is practiced in this culture. Semi-structured interviews were conducted with twenty-five gaming industry figures and gamers. Thematic analysis was used to guide data collection and analysis. The findings indicate that glocalisation, socialised gaming practices and competitiveness characterise the Vietnamese gaming experience. The distinct culture of Vietnam combined with globalised gaming consumption habits has created new modes of play culture, and hence leisure experiences that are growing in pervasive and influential ways. 相似文献

Spillover effects within randomized clusters pose a challenge for identifying impacts of an individualized treatment. The paper proposes a solution. Longitudinal and intra‐household observations are combined in estimating the direct knowledge gain from watching an info‐movie in rural India, while randomized village assignment identifies knowledge sharing. Simulations on synthetic data and econometric tests provide support for the estimation method. We find evidence of information sharing, but far less so for disadvantaged groups, such as illiterate and lower‐caste individuals; these groups rely more on actually seeing the movie. Our results are consistent with sizeable biases in ordinary least squares, matching or instrumental variable impact estimators that ignore within‐cluster spillovers. 相似文献
