China's industrial state-owned enterprises (SOEs) have seen a secular decline in profitability throughout the reform period. Barry Naughton argues that this decline was in large part due to a decline in monopoly rents as competition with enterprises in other ownership forms increased. Fan Gang and Woo Wing-Thye, on the other hand, contend that profitability declined across all sectors independent of the degree of competition, and that excessive labor remuneration accounts for the broad decline in SOE profitability. Testing the two hypotheses with aggregate sectoral and provincial data from the mid-1980s to the late-1990s, neither appears convincing. Yet at closer inspection these are not competing hypotheses. The two causes affect overall profitability through different channels. Competition and labor remuneration have a highly significant impact on intermediate profitability measures that take the two channels into account separately. Together they explain most of the variation in overall profitability.  相似文献

Japan's need for economic and political reform has been recognized but the means to achieve this has not. In this article, J.A.A. Stockwin, professor of Modern Japanese Studies at the Nissan Institute of Japanese Studies, University of Oxford, considers this question by examining the meaning of democracy then applying the theory to the specific case of Japan. He explains that although not identical to a democracy in a Western sense, Japan's system of government is genuinely democratic. Stockwin argues that Japan is now at a crossroads in her history, but before pressing for reform an understanding of the complexity of the Japanese system is necessary. He concludes that a radical restructuring of Japan's political party system towards a bipolar set of party arrangements is necessary but questions whether Prime Minister Junichirô Koizumi is up to the task.  相似文献

In the present article, we empirically analyse a series of competing hypothesis that try to account for the considerable disparity in the tax burden between Swiss cantons. Three hypotheses focus on differences in spending levels: The first explains differences in the tax burden with differences in citizens' demand for government services. The second emphasizes the differences in efficiency between cantonal administrations, whereas the third insists on the more or less easy access to cantonal instruments of direct democracy. However, when confronted to the data, none of these three expenditure‐based hypotheses are confirmed by our cross‐sectional estimations. On the contrary, our regressions lend support to the hypotheses which highlights the differences in tax revenues between cantons. These results suggest that it is not differences in government spending which account for the disparity in cantonal tax levels, but differences in the cantonal endowment with resources. This indicates that some financial equalization on the cantonal level might strengthen the equity of Switzerland's tax system.  相似文献

We investigated the relation between urban psychosocial stressors and intimacy achievement in a sample of 59 African American, Hispanic American, and White adolescent fathers-to-be. Participants received an intimacy score based on Orlofsky's Intimacy Status Rating Scale. Those with higher cumulative psychosocial stressors had lower levels of intimacy. One psychosocial risk factor, low interpersonal empathy, was significantly associated with intimacy levels. African Americans had lower levels of intimacy than Hispanic or White participants.  相似文献

The primary aim of this study was to compare the willingness of sexually abused (n = 22) and non–sexually abused (n = 36) late adolescent women to self-disclose both general and sexual information to strangers and intimate partners. Results, based on a sample of college women, indicate that those who were sexually abused in childhood are less likely than nonabused counterparts to be highly disclosing of sexual and general information to intimate partners. Avoiding extensive disclosure of personal information to intimate partners may serve to keep survivors of abuse at a relatively safe distance from their own dysphoric feelings and suggests that mistrust of others is an ongoing issue for this population.  相似文献

This article examines the selection and use of a budget approval technique. Specifically, two research questions are addressed: (1) Does the use of a particular budget approval method by a governmental body impact the execution of the budget? (2) What characteristics of a local government are associated with its decision to use a particular budget approval method? Both research questions are addressed by analyzing data from public school systems in the Commonwealth of Virginia, specifically, whether using categorical budget approval differs in the accuracy of budgeting versus using a lump-sum approval method. Characteristics of Virginia school districts are also analyzed according to whether any of them are likely to be associated with school districts using a particular approval method. The remainder of this article is organized as follows: the next section describes the role of budgeting control in schools; subsequent sections review Virginia school district budgeting practices, develop the empirical model used to test the hypotheses, describe the sample, analyze the results of empirical tests and discuss implications of the findings.  相似文献
