We investigate the effect of financial integration on a banking crisis. In contrast to existing works, we allow for capital restrictions while studying the impact of financial integration on a banking crisis. Using firm-level lending and borrowing information in the global market of syndicated loans; we generate aggregate measures of financial integration and examine how countries with capital flow restrictions thrive in the wake of a banking crisis. We concentrate on basic network measures of integration for a panel of 62 countries that allow for capital restriction at any time within the sample period. Financial integration increases the incidence of a banking crisis, and capital restrictions worsen a banking crisis. However, capital restrictions reduce the negative impact of financial integration on the incidence of a banking crisis. Thus, financial integration becomes beneficial when countries allow for some forms of capital control.  相似文献

Preparing qualified graduates for the tourism and hospitality industry who will stay and achieve promotional success is paramount. The objectives of this research project were to determine promotional advancement expectations and strategies to improve promotional opportunities. Two separate questionnaires, with both open and close-ended questions, were sent to upper classmen/women in hospitality and tourism programs and alumni of the same programs. In total, 717 (409 students and 308 alumni) completed the questionnaires. Chi-square tests were run to determine differences between student and alumni responses. To assist in analysis of open-ended responses, Atlas.ti was used. There was a statistically significant difference between students and alumni responses in regards to promotional expectations; students expected it to take a significantly longer time to receive a promotion to supervisor or manager than alumni. Overall, students and alumni indicated strategies such as more real-world-focused courses with hands-on experiences.  相似文献

We show that local house prices may be driven almost entirely by the demands of one identifiable group for several years and then by demands of another group at other times. We present evidence that house prices in Hawaii were subject to such regime shifts. Prices responded to demands associated with U.S. incomes and wealth for most years from 1975 through 2008. For about a decade starting in the middle of the 1980s, after the Japanese yen appreciated dramatically and Japanese housing and stock market wealth soared, however, house prices in Hawaii responded to Japanese incomes and wealth. Estimated models with these regime shifts outperformed conventional, constant‐coefficient models. The regime‐shifting model helps explain why, when and by how much the volatility and the elasticities of house prices in Hawaii with respect to the incomes and wealth of the United States and Japan varied over time.  相似文献

Scotland's tourism product has its own national identity which is derived from the distinctive character of the country's climate, culture, tradition, and industrial and social history. In this report John Stuart, Director of External Relations at the Scottish Tourist Board, describes the new techniques that have been devised to manage the tourism industry in Scotland and promote its product in the UK and overseas.  相似文献

This article examines relationships between stress, health, and participation in physically active leisure using data collected as part of the 1985 and 1990 U.S. National Health Interview Surveys (NHIS). In particular, the article analyzes: (a) the effects of life‐cycle progression (controlled for gender) on subjectively perceived stress and self‐reported health; (b) the role of physically active leisure in enhancing health or buffering adverse health outcomes of stress; and (c) the effects of selected social‐economic factors, such as education and income, on the relationships between life‐cycle, stress, health, and physically active leisure. According to our analyses: (1) stress is unevenly distributed across the life span; (2) stress‐reducing effects of physically active leisure are present among retired older people more so than in the middle‐aged life‐cycle groups; and (3) direct health‐enhancing effects of participation in physically active leisure are more evident than the buffering effects of leisure on stress‐health relationships. A critical discussion of methodological and substantive issues facing researchers interested in the relationships between leisure, stress, and health is provided.  相似文献

The medical expense deduction (MED) allows taxpayers to deduct from taxable income a proportion of their out-of-pocket medical insurance and health care expenses. Because the rate of subsidy is equal to the marginal tax rate previous studies have found MED to be a regressive tax mechanism biased toward benefiting higher-income taxpayers. The authors demonstrate, using GINI coefficients, that MED makes the tax structure more progressive than it would otherwise be and increases equality of after-tax incomes.  相似文献
