We introduce a new theory of industry evolution. According to our model, the nonmonotonicity in firm numbers found in many young industries is a consequence of the gradual decline in unit costs. Early stages of the industry life cycle, when unit costs and profit margins are high, display positive net entry rates. In later stages, declining unit costs and increasing competition limit the market room for (fringe) firms accumulating in a shakeout. The model explains paths of output, price level, and firm numbers using a recursive system of equations. We apply the model to the U.S. tire industry.  相似文献

Using firm-level Japanese FDI data on investment into 18 European countries between 1970–2000 in all industries (banking, manufacturing, wholesale/retail distribution, and business services), this study examines if the “follow the customer” (FTC) hypothesis holds for firm-level data. The results suggest that banks do follow their customers into a foreign market, as part of a larger strategy that goes beyond the FTC theory. The firm level data show that the majority of FDI into a host country occurs after the foreign bank has established operations. Policy implications of this finding include the suggestion that host economies liberalize their financial sector early in an effort to attract banking FDI which then will attract non-banking FDI rather than the reverse.  相似文献

After the EU enlargement in 2004, there is a clear commitment of the EU and the new member states to aim at an enlargement of the euro zone within the European Economic and Monetary Union (EMU) as well. This might have significant effects on the old EMU, the new members, and even on the global economy. The present paper analyzes some macroeconomic effects and particularly the impact on the effects of stabilization policies when switching to an enlarged euro zone under different assumptions about fiscal and monetary policy regimes in Europe and under alternative types of economic shocks. Also, the implications for the US of different European monetary regimes are evaluated. The results suggest that economic benefits for all countries are rather small. For the Central and Eastern European countries (CEECs), even disadvantages may dominate.  相似文献

This empirical study seeks to broaden the interpretation of the rational voter model so as to identify and better understand key determinants of the expected benefits from voting and hence key determinants of the aggregate voter participation rate in the US. Using annual data for all years in the 1960–1997 study period, this study finds that the voter participation rate has been positively impacted by strong public approval or strong public disapproval of the incumbent President, a finding unique to this literature and study period. In addition, the aggregate voter participation rate has been positively impacted by such factors as the Gulf War, which is generally regarded as having been popular among the US electorate, and a rising unemployment rate. This study also finds the voter participation rate to have been negatively impacted by the publics dissatisfaction with government, as well as by the Watergate scandal.The author is indebted to Cassandra Copeland for helpful information, comments, and guidance.  相似文献

The aim of this paper is to explore the relationship between income inequality and health in the European Union countries using new data from the European Community Household Panel (ECHP). The heterogeneity of the households has been approached using different equivalence scales. A variety of different model specifications were tried using different dependent variables such as life expectancy at birth and child mortality. The results give support to the influence of income inequality on health indicators using aggregate data and panel techniques, and show the sensitivity of the Gini index to the equivalence scale considered.  相似文献

Spot to retail price pass-through behavior of the U.S. gasoline market was investigated at the national and regional levels, using weekly wholesale and retail motor gasoline prices from January 2000 to the present. Asymmetric pass-through was found across all regions, with faster pass-through when prices are rising. Pass-through patterns, in terms of speed and time for completion, were found to vary from region to region. Spatial aggregation was investigated at the national level and the East Coast with the aggregated cumulative pass-through being greater than the volume-weighted regional pass-through when spot prices increase. These results are useful to the petroleum industry, consumers, and policy makers by providing a basis to estimate the retail price effects that result from a change in spot price.  相似文献
