We use the sensitivity of bank holding company equity returns to market interest rates as an indicator of perceived maturity mismatch. Based on data from 1990 to 2009, there is only weak evidence that market participants perceived banks to be effectively short‐funded. However, looking at 1990–1996 and 1997–2009 subsamples separately, our results suggest that U.S. commercial banks were perceived as short‐funded during the earlier time period but not the later. During this time of changing perceptions of maturity mismatch, banks were increasing their holdings of real estate loans as a share of total assets. We present evidence that, subsequent to 1996, market participants perceived real estate loans as having become effectively shorter‐term.  相似文献

We reveal an interesting convex duality relationship between two problems: (a) minimizing the probability of lifetime ruin when the rate of consumption is stochastic and the individual can invest in a Black–Scholes financial market; (b) a controller-and-stopper problem, in which the controller controls the drift and volatility of a process in order to maximize a running reward based on that process, and the stopper chooses the time to stop the running reward and pays the controller a final amount at that time. Our primary goal is to show that the minimal probability of ruin, whose stochastic representation does not have a classical form as does the utility maximization problem (i.e., the objective’s dependence on the initial values of the state variables is implicit), is the unique classical solution of its Hamilton–Jacobi–Bellman (HJB) equation, which is a non-linear boundary-value problem. We establish our goal by exploiting the convex duality relationship between (a) and (b).  相似文献

This article examines the changing role of financial accounting in the former East Germany as that country underwent the transition from a centrally planned to a market-driven economy. The German government's insistence on a sales model of privatization in preference to some form of mass privatization, combined with legal requirements to make up equity shortfalls in eastern German enterprises, resulted in a highly centralized and interventionist approach to accounting change. The article reviews and analyses the historical, technical, economic and political aspects of this change process.  相似文献

The price of parking is often considered an important tool with which to influence transport choice but, since many local authorities have limited control over off-street charges and since parking charges have no direct impact on through traffic, its influence on overall travel demand may be limited. Road user charges, on the other hand, do appear to offer an effective means of influencing overall demand. The problem is that public acceptance of such charges is low unless some obvious “carrot” can be identified. This paper explores the possibility that the removal of parking charges might be that “carrot”. Our analysis suggests that, although the removal of parking charges would reduce revenues and dilute the reduction in demand caused by the introduction of road charges, the combined effect might, in certain circumstances, be more beneficial to the local economy and might still yield a net increase in revenue. Given the incidence of impacts, it also appears that a combined scheme would be more equitable and might stand a greater chance of achieving public acceptance than a more conventional road charging scheme. The paper identifies the circumstances in which a combined scheme might work well and outlines the detailed analysis that would be necessary to confirm this.  相似文献

To create new opportunities for nurses to reenter the workforce, a RN p.r.n. program must meet the needs of nurses who wish to make dual commitments to home and work. The Parent Shift program provides an innovative model of attracting and retaining nurses in a hospital workforce. Many nurses who joined the program were away from the field of nursing for many years and were drawn to the program because of the promise of flexible shifts and minimal requirements for participation. In this study, flexible shifts not only encouraged program entry, they were also a powerful motivator for continued program participation over time. Parent Shift nurse presence was perceived by nurse managers to decrease stressors and improve time efficiency of full-shift staff.  相似文献

This research tested a conceptual model for proximity of clothing to self (PCS) in relation to age identity, self‐actualization, psychological well‐being, self‐assessed health, sex and chronological age among older adults, aged 65 and over, within the human ecological perspective. A mail survey was sent to a national random sample of 1700 older adults in the US resulting in 195 usable respondents in the final sample. The respondents returned two completed questionnaires, which were (1) Clothing: A Resource for Successful Aging? (to measure PCS, age identity and demographic variables) and (2) Personal Orientation Inventory (to measure self‐actualization). The results indicated that older adults' psychological well‐being, one component of successful ageing, was directly affected by their self‐assessed health, age identity and self‐actualization. PCS indirectly influenced individuals' psychological well‐being in a slightly negative way in later life. In sum, clothing may be used as a needs satisfier for different levels of needs or related more closely with needs in addition to self‐actualization needs for older adults. Further research should be conducted to explore relationships among PCS, different levels of human needs, clothing‐related variables and psychological well‐being for this age group. In practice, the effort should be given to teach the use of clothing (or other human‐built objects) as a tool or need satisfier to contribute to success in a person's later life by offering some educational or training programmes through local senior community centres or universities.  相似文献
