We examine fluctuations in the predicted educational attainment of newly arrived legal U.S. immigrants between 1972 and 1999 by combining data from the U.S. Immigration and Naturalization Service with the Current Population Survey. A mid-1980s decline gave way to a noticeable improvement in the skill base of the immigrant population between 1987 and 1993. A short decline in the quality of immigrant skills—less severe than that of the mid-1980s—took place in the mid-1990s. In 1998, the trend reverses once more: The labor market quality of new legal U.S. immigrants improves. The primary sources of the fluctuations include changes in the quality and quantity of immigrants obtaining an adjustment and variations in the distribution of source regions and entry class types among new legal U.S. immigrants.  相似文献

While the Chandlerian firm has come to dominate large sectors of advanced economies, recent studies have shown that the properties of knowledge used by firms, the dynamic nature of transaction costs, and the impact of information and communication technologies on organisations might reduce firm scale and scope. We present a contingent model of firm boundaries that explains why, as a result of technological change, firms might simultaneously outsource some activities that they had formerly preferred to produce in-house while increasing their vertical integration in other areas. We support our conclusions with evidence from different industries.  相似文献

The integration of national economies of a different level of development and an opposite quality of system will have a more profound influence in shaping the world of tomorrow. Therefore a theory of economic integration must be formulated which transcends the existing systems, i.e. a theory of co-integration.  相似文献

The Soviet Union will not be represented at the North-South Summit in Cancún, even though both the developing countries and the Western industrialised countries would have liked to see it participate in the talks on solving the problem of underdevelopment. What are the USSR’s reasons for its negative attitude? Are there any prospects of involving the Soviet Union and its CMEA partners in joint development cooperation?  相似文献

This paper estimates technical efficiency (TE) measures using four alternative production frontier models, and evaluates the sensitivity of the results to the choice of methodology. The Cobb-Douglas functional form along with data for 1982 and 1983 from 404 dairy farms located throughout six northeastern states in the US are used in the estimation. A general conclusion is that, broadly speaking, frontier function models are neutrally upwardly scaled versions of the OLS or average model. A second conclusion is that different models yield markedly different efficiency levels across firms. However, the correlation between the indexes from the various methods is high, which implies that the ordinal ranking of firms according to their measured level of technical efficiency appears to be independent of the method used for a given year. By comparison, the correlation between efficiency indexes for the same method across time, although positive, is much lower than the previous set of correlations. Correlation analysis of efficiency versus farm size and of efficiency versus returns over variable costs, based on the alternative models, yielded consistent results.  相似文献

The creation of the Asian Infrastructure Investment Bank (AIIB)was welcomed by the World Bank but opposed by the Obamaadministration. The paper explains China’s positive relationshipwith the Bank and the Organization for Economic Cooperation andDevelopment (OECD) in terms of the mission of the Bank, sharedby the OECD, to develop and deepen the global economy. The AIIBand the related Belt and Road initiative promise to do this throughinvestment in infrastructure and connectivity in and around thepoorly integrated Eurasian landmass. But while the current Chineseleadership has supported an inclusive global economy based uponfree trade and supported by multilateral institutions, China’s controlof resources outside the multilateral framework and adherence topractices that challenge liberal principles prompt suspicions thatthese commitments are either disingenuous or anyway subjectto reversal. In itself, therefore, the AIIB provides no conclusiveevidence either way on China’s future course.  相似文献

The diffusion of a novel taxing scheme (among Dutch municipalities over the period 1998–2005) is studied in which the waste disposal tax is increasing in the amount of waste a household produces. Inspection of the rise and spread of this tax shows that it is contagious: the probability of introduction is increasing in the number of neighboring municipalities that have already introduced this taxing scheme. A possible rationale is that the tax encourages the dumping of waste in neighboring municipalities. These municipalities may then introduce a similar tax to prevent dumping (spillover effect). Using panel data and a recently developed spatial probit approach (Elhorst et al. in J Appl Econom 32:422–439, 2017), it is possible to distinguish this spillover effect from time-specific effects. The results indicate the presence of strong spillovers.  相似文献
