In this paper, we argue that credit market imperfections impact not only the level of unemployment, but also its persistence. For this purpose, we first develop a theoretical model based on the equilibrium matching framework of Mortensen and Pissarides (1999) and Pissarides (2000) where we introduce credit constraints. We show these credit constraints not only increase steady-state unemployment, but also slow down the transitional dynamics. We then provide an empirical illustration based on a country panel dataset of 20 OECD countries. Our results suggest that credit market imperfections significantly increase the persistence of unemployment. 相似文献

Abstract This paper is an empirical study of the publication records of communications to a weekly seminar, continued from 1997. We look at the quality of publications, and also at the determinants of publications. Our results offer lessons for both presenters and organizers of research seminars in academia. 相似文献

CRITICAL PRICE NEAR MATURITY FOR AN AMERICAN OPTION ON A DIVIDEND-PAYING STOCK IN A LOCAL VOLATILITY MODEL 总被引:3,自引:0,他引:3
We consider an American put option on a dividend-paying stock whose volatility is a function of the stock value. Near the maturity of this option, an expansion of the critical stock price is given. If the stock dividend rate is greater than the market interest rate, the payoff function is smooth near the limit of the critical price. We deduce an expansion of the critical price near maturity from an expansion of the value function of an optimal stopping problem. It turns out that the behavior of the critical price is parabolic. In the other case, we are in a less regular situation and an extra logarithmic factor appears. To prove this result, we show that the American and European critical prices have the same first-order behavior near maturity. Finally, in order to get an expansion of the European critical price, we use a parity formula for exchanging the strike price and the spot price in the value functions of European puts. 相似文献

The closure of coal mines and local development responses in Coal-Rim Cluster,northern KwaZulu-Natal,South Africa 总被引:1,自引:0,他引:1

The impact of mine closure can have a devastating effect on the local economies of the towns that they once supported. Drawing on comparative, international material, this article examines the nature and effectiveness of the local economic development responses that have been initiated in the former coal-mining towns in northern KwaZulu-Natal in South Africa. Although a range of innovative locally identified strategies have been embarked upon, considerably greater effort and investment will be needed in order to catalyse significant and meaningful regeneration endeavours. 相似文献

When evaluating a product or service, consumers seek out information to judge whether that specific product will meet certain criteria. The main concern of sales providers is how to increase their purchasers' willingness to buy a product. The authors studied the impact of age on the perceived importance and interaction of three factors known to influence people when buying clothes: price, durability and suitability. A sample of 160 French adults aged 18–90 rated their likelihood of buying an item of clothing in 27 scenarios, in which three levels (low, moderate and high) of each of the above three factors were combined in an orthogonal factorial design. For younger participants, a low price was considered a sufficient reason to buy the item of clothing. For older participants, suitability was a more important factor, while for the eldest people, durability was the most important. 相似文献

The importance of the institutional environment on multifunctional farming systems in the peri-urban area of Brussels 总被引:6,自引:1,他引:5

The influence of local and regional policies on the uptake of multifunctional farming systems is analysed. The conceptual framework of how regional and local policies can influence farmers’ behaviour is empirically verified by analysing data on uptake of diversification and environmental management by farmers located in the Brussels’ peri-urban area. In a two-stage model, farmers’ participation and behaviour to influence local policy-makers is also examined. It has been found among other things that, in a municipality that attaches greater importance to environmental issues, the uptake of agri-environmental measures is higher and that promotion of local agriculture will encourage farmers to start processing or selling products on their farms. 相似文献

Background Intentional injuries due to violence are both a social and a public health problem in most societies. This study assesses the patterns and some of the sociodemographic determinants of violence-related injuries among Greek adults. Methods Data recorded by the Emergency Department Injury Surveillance System (EDISS) during the two-year period 1996-1997 were used. This database relies on all age injury data collected in the emergency departments of three sentinel hospitals, covering both urban and rural population areas. Results Among 52026 recorded injuries, 1322 (3%) were violence related, excluding self-inflicted injuries, while the majority of injuries (28269) were attributed to home and leisure accidents. Weapons of any type were used only in 5% of violence-related injuries. In comparison to home and leisure injuries, the intentionally inflicted injuries occurred more frequently among men, among those 25-54 years old, and were particularly common among migrants and during late night and early morning hours. Violence-related injuries frequently occur in pubs, restaurants, cafeterias and other places of entertainment. However, 52% of violence-related injuries among women occurred at home. Intentional injuries were generally more severe than unintentional ones. Conclusions We conclude that violence is not a negligible public health problem in the Greek population, but is considerably less serious than in most other developed countries. In particular, firearms-related injuries represent a very small fraction of the generally low incidence of violence-related injuries in this Mediterranean country. 相似文献

We provide estimates of the abnormal stock market returns associated with pharmaceutical firms’ announcements of technological and regulatory successes in drug development. On the basis of these estimates, we find empirical support for two key features of technological race models. First, we observe that leaders in the innovation race record higher abnormal returns than do latecomers when they announce a success. Hence, firms should indeed be racing to complete the innovation process before their rivals. Second, pharmaceutical firms are adversely affected by the technological and regulatory success of their rivals, implying that interfirm spillovers in drug development are not sufficient to offset technological rivalry. Additional results are also produced regarding the impact of competition on R&D racing and the extent of therapeutic competition. 相似文献

It has been recognized that learning outcomes can be divided into three general categories: Cognitive, skill-based, and affective
learning. Moreover, public organizations offer mentoring-inspired support programs to novice entrepreneurs starting a business.
This study explores entrepreneurial learning through mentoring. We have coded 53 learning outcomes acquired by novice entrepreneurs
through their mentoring relationship. These learning outcomes were analysed using the three general categories and linked
with the mentor’s way of promoting learning. Cognitive learning accounts for 62% of total learning outcomes and affective
learning makes up 35.9%, which leaves skill-based learning in a marginal position. In addition, methods used by the mentor
to ensure mentee learning affect learning content. Mentees were also asked to describe the benefits of their mentoring relationship
through discussion groups. From a cognitive learning standpoint, benefits reported by entrepreneurs include an increase in
management knowledge and skills, improved vision for their business venture and identifying new opportunities. Benefits resulting
from affective learning include a greater sense of self-efficacy, validation of one’s entrepreneurial self-image and a lowered
sense of solitude, all factors that could ultimately influence entrepreneur resilience. These results reveal the scope and
limitations of mentoring as means to support learning. 相似文献
