In this paper, we employ parametric and nonparametric techniques to analyse the effect of market potential on the structure and growth of Spanish cities during the period 1860–1960. Even though a few attempts have been made to analyse whether market potential might influence urban structures, this period is especially interesting because it is characterised by advances in the economic integration of the national market together with an intense process of industrialisation. By using an elaborated measure of market potential at the city level, our results show a positive influence of this market potential on city growth, although this influence is heterogeneous over time. Only changes in the market potential from 1900 have a significant effect on population growth.  相似文献

While extensive, the existing literature on the employment-at-will doctrine and its various exceptions has been remarkably uniform. By relying on a discussion of selected court opinions on specific aspects of the doctrine, scholars have focused primarily on normative issues such as what the courts should do when deciding job security disputes, or what plaintiffs/employees and defendants/employers should argue when litigating employment disputes. Our approach and focus are different. Instead of relying on a discussion of selected cases, we rely on a more comprehensive sample of cases. Instead of focusing on normative issues, our goal is to provide a more complete picture of the state of the at-will doctrine as reflected in those cases. Our data should be of interest to legal scholars interested in understanding the characteristics and outcomes of litigated employment-at-will cases. Our data should also be relevant to the current debate among management scholars regarding conflicts that might arise due to aggressive recruitment practices which highlight long term employment opportunities and the realities associated with at-will employment.  相似文献

We introduce a new data set on hiring and firing restrictions for 21 OECD countries for the period 1984-1990. The data are based on surveys of business people in the countries covered, so the indices we use are subjective in nature. Controlling for country and time fixed effects, and using dynamic panel data techniques, we find evidence that increasing the flexibility of the labor market increases both the employment rate and the rate of participation in the labor force. A conservative estimate suggests that if France were to make its labor markets as flexible as those in the US, its employment rate would increase 1.6 percentage points, or 14% of the employment gap between the two countries. The estimated effects are larger in the female than in the male labor market, although both groups seem to have similar long-run coefficients. There is also some evidence that more flexibility leads to lower unemployment rates and to lower rates of long-term unemployment. We also find evidence consistent with the hypothesis that inflexible labor markets produce “jobless recoveries” and introduce more unemployment persistence.  相似文献

This paper provides two new data sets for comparisons of real income in OECD countries. The first set provides adjusted real series for GDP and its components from 1960 to 1993 based on OECD 1990 purchasing power parities. The second set uses OECD PPP of different benchmark years, and interpolates these applying national price indices. Comparisons between both alternatives, Penn World Tahle Mark 5 (PWT 5) and its new version (PWT 5.6), in terms of economic growth and convergence, reveal some remarkable differences. Moreover, there are wider differences concerning the relative countries' position in GDP per capita ranking. Estimations of convergence equations based on OECD data yield a better fit than those obtained using PWT data, although there are also some significant differences between PWT 5 and PWT 5.6. Nevertheless, a very positive result is that other parameters of interest in these equations are not affected by the use of these different data sources.  相似文献

For decades, the analysis of public spheres has been a core field in communication science and neighboring disciplines. Its special importance is grounded in the assumption that the public sphere is the primary realm of societal self-understanding, a sphere in which collectively relevant issues, potential solutions and the activity of political and other stakeholders is discussed and put up for scrutiny and legitimization. In much of this research, the media have played a key role, as they were seen as the generally accessible, permanent and comprehensive “master forum” of the public sphere.In recent years, however, scholarship on the public sphere has undergone a “major theoretical shift”, namely, a widening of the analytical perspective from national to transnational concepts of public spheres. Against the backdrop of a general transnationalization of the social sphere, communication scholars have increasingly paid attention to transnational forms of public sphere(s). Many of them, however, have focused on the (potential) emergence of a European public sphere in light of the expansion of the European Union, and only recently has research started to address transnational public spheres beyond Europe.This study ties in with this field of research. An empirical analysis of (potential) transnational public spheres was conducted by focusing on a subject which has been interpreted as a focal point for the emergence of a transnational or even global public sphere: international climate change policy. Due to its high priority and wide reach, international climate policy is said to constitute conditions conducive for a potential transnationalization of public spheres.We understand transnationalization as a pervasion of national public spheres with transnational references that can be distinguished along two analytical dimensions: “Vertical” transnationalization describes the extent to which organizations and actors representing a form of supranational governance are represented and/or (de)legitimized in national public spheres. The “horizontal” transnationalization describes the extent to which organizations or actors from foreign countries are represented within national public spheres.In addition, we differentiate a “strong” and “weak” variant of vertical resp. horizontal transnationalization. For example, a “weak vertical transnationalization” characterizes a case where supranational governance institutions are merely mentioned within a national public sphere; whereas a “strong vertical transnationalization” characterizes a situation where actors from supranational governance institutions have the opportunity to actively express themselves.Our main research questions are 1) to what extent is the media coverage about climate policy in the examined countries pervaded by transnational references? 2) Which patterns of transnationalization can be identified in the media coverage about climate policy in the examined countries?We conducted a manual as well as an automated quantitative content analysis of newspaper coverage about climate change policy in 15 countries. We analyzed 4955 news articles from quality, tabloid and local newspapers for the whole year of 2014. The articles were downloaded from databases like LexisNexis and Factiva, using a complex search string in four languages. The automated content analysis—used to identify the weak variant of transnationalization—followed the “dictionary approach”, with dictionaries based on elaborated word lists (in German and English) that were translated into Portuguese and Spanish and further adapted for this study. The results of the automated content analysis were tested against a manual analysis of 50 randomly selected articles, with very good reliability for each language-specific dictionary (Krippendorff’s Alpha above 0.909). Regarding the manual content analysis—used to identify the strong variant of transnationalization—11 coders were trained and achieved a satisfying to good reliability (Krippendorff’s Alpha above 0.72).Firstly, our analysis shows a visible transnationalization of public debates about climate change policy. In all countries, foreign and supranational actors dominate the domestic news coverage (weak pattern). Conversely, regarding the strong pattern of transnationalization national actors who actively express themselves are dominant.Secondly, our findings show that the transnationalization of the public sphere differs depending on the dimension examined. On the one hand, the horizontal transnationalization appears more often than the vertical one: References to actors from other countries in climate policy-related debates appear more often than references to supranational institutions. On the other hand, transnational references tend to appear rather in a weak than a strong pattern: Foreign or supranational actors are mentioned more often than they express themselves actively. Furthermore, transnational references seem to concentrate on a few actors like the UN, the EU, China and the USA.Thirdly, we found country and media type-related differences regarding the extent, structural patterns and reach of transnationalization. Media type differences seem to correspond with the findings research about European public sphere yielded: News coverage of quality papers is more transnationalized than regional and especially tabloid papers.  相似文献

A simultaneous-equations model is developed for the reciprocal relationship among bilateral trade value, conflict, and cooperation by modeling the actions of exporters, importers, and governments. The model is estimated separately for each of the dyads among the US, the USSR, China, Japan, and (West) Germany for the yearly data from 1948 to 1992. The direction of the effects of conflict or cooperation on trade and that of trade on conflict or cooperation are generally mixed, as expected. Certain reciprocal relationship patterns emerge depending on whether countries belong to the East or West block.  相似文献

We present a new measure of legal protection of minority shareholders against expropriation by corporate insiders: the anti-self-dealing index. Assembled with the help of Lex Mundi law firms, the index is calculated for 72 countries based on legal rules prevailing in 2003, and focuses on private enforcement mechanisms, such as disclosure, approval, and litigation, that govern a specific self-dealing transaction. This theoretically grounded index predicts a variety of stock market outcomes, and generally works better than the previously introduced index of anti-director rights.  相似文献

This paper estimates a theoretically‐motivated gravity model to examine the effect of the European Union (EU) on trade and whether the order of entry has affected the trade performance of member countries. Additionally, we analyse the impact of the different phases of EU integration on trade. The results show that both original countries and successive enlargements boost intra‐bloc trade. Moreover, the results suggest that the deepening in the integration process has led to more trade creation among members. Finally, only the latter phase of the European integration process (the single currency) has increased trade with non‐members.  相似文献
