In this article we compare bivariate and multivariate models for homogamy of social origin and education to test whether bivariate models of homogamy lead to biased results. We use data on Hungarian couples married between 1930 and 1979 and loglinear models of scaled association. The results indicate some differences between bivariate and multivariate analyses. At each point of time bivariate models overestimate homogamy, both with respect to education and social origin. However, results on trends in time do not differ much between the two analyses. The exception is the period 1940–1959, in which bivariate analysis showed decreasing educational homogamy, and multivariate analysis showed an increasing trend. The latter finding can be explained by declining homogamy of social origin, as well as the weaker reproduction and cross-effects in this period. 相似文献

专门化、多样化和中国地区工业产业增长的关系 总被引:18,自引:2,他引:16

本文通过分析中国29个省(除西藏外)的30个工业产业在1988-1997期间的数据。揭示了工业结构和经济增长之间的关系。本文除研究了传统的生产要素的影响外,重点探讨了产业专门化、专业多样化、竞争度和一省发展的初始水平等因素的作用。结果表明,一个产业外部工业环境的多样性和产业内的竞争度有利于产业的增长,但产业专门影响为负。工业结构对于增长的影响在很大程度上依赖于产业的性质及其地理位置。 相似文献

This study compares the patterns of entry, survival and growth of domestic and foreign owned firms. We show that the post-entry behavior of foreign owned firms is quite different from that of their domestic counterparts. Among foreign entrants, we were able to distinguish between those which proceed by creating a new firm and those that acquire an already existing business. Our evidence reveals that the choice of the mode of entry in foreign markets exerts an impact upon the performance of firms that persists long after the moment of entry. As a consequence, our work clearly indicates that there is much to be gained in the understanding ofthe process of entry in foreign markets by studying the behavior of entrants over their first years in these markets. 相似文献

The impact of demand growth on the collusion possibilities is investigated in a Cournot supergame where market growth may trigger future entry and the collusive agreement is enforced by the most profitable ‘grim trigger strategies’ available. It is shown that even in situations where perfect collusion can be sustained after entry, coping with a potential entrant in a market which is growing over time may completely undermine any pre‐entry collusive plans of the incumbent firms. This is because, before entry, a deviation and the following punishment phase may become more attractive thanks to their additional effect in terms of delaying entry. 相似文献

We use an original database of 5000 French local public authorities to explore the impact of organizational choice and performance as measured by consumer prices. In quantifying the impact of the choice of public-private partnerships (PPPs) on performance, we consider the related issue of the determinants of organizational choice. We estimate a switching regressions model to account for the endogeneity of organizational choice, and find that in our sample, (i) the choice by local public authorities to engage in a PPP is not random, and (ii) conditional on the choice of a PPP, consumer prices are significantly higher on average. 相似文献

This paper presents MAcMap–HS‐6, a database providing a consistent, ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six‐digit level of the Harmonized System (5111 products), accounting for all preferential agreements. We describe the methodology used to compute and aggregate an ad valorem equivalent of applied protection. Emphasis is placed on minimizing the endogeneity bias in the aggregation procedure, while acknowledging structural differences in export specialization. The resulting quantitative assessment is illustrated by giving an overview of applied protection across the world in 2001, in terms of average as well as distribution. 相似文献

As managers and employees from different cultures begin to encounter one another in the workplace, the need arises to understand how organizational variables relate differentially based on one's culture. This study attempts to provide a preliminary examination of the relationship between stressors, sources of conflict and job commitment across two differing cultures, specifically the United States and Hong Kong. Although more similarities than differences between the two cultures were found, this study provides at least preliminary evidence that members of different cultures may perceive some stressors differently and exhibit different relationships between stressors and work attitudes. 相似文献

The law of one price (LOOP) is an essential foundation of both the pure theory of trade and monetary theory. Strictly speaking, the law relates to prices of individual commodities. However, empirical tests of LOOP have often relied on aggregated data. In this paper, a model is derived and estimated using price data for 15 selected inputs in New Zealand agriculture. The results offer no support for the LOOP in the short run, and the results for the long run are mixed. It may be inappropriate, therefore, to assume that the LOOP holds generally in modelling exercises, particularly when models are used for policy purposes. 相似文献
