This article models the riskiness of structured securitization deals. The deals are put together by “banks,” which can exercise strategic options over the risk put into the deals. The banks face a trade‐off between the benefits of risk‐taking now and future franchise benefits if the deal pays off. The key insight is a convex relationship between the value of the bank's equity position and the risk in the deal. Although there is a continuum of possible risk, banks choose either the highest or lowest levels of risk open to them. Changes in strategy are discontinuous and unpredictable; a history of low risk‐taking may be a prelude to increased risk‐taking later. Competition, to the extent of reducing franchise value, can lead to more risk‐taking, as can more information in the market. The model provides insights into the risk‐taking that led up to the Great Recession and to institutions that are “Too Big to Fail.” 相似文献

Over the last several years, the price of listed real estate stocks has been unusually high relative to dividends. I find that neither low interest rates nor low risk premia can account for the high valuation ratios. Lower interest rates have been offset by rising risk premia to keep expected returns close to average. Instead, the market has priced in future income growth on commercial properties far above the growth rates seen in the data. High implied growth rates are less extreme for nontraditional REIT sectors. Income growth expectations are also less extreme for international listed real estate. 相似文献

Raising the minimum wage has been advanced as complementary policy to comprehensive immigration reform to improve low‐skilled immigrants’ economic well‐being. While adverse labor demand effects could undermine this goal, existing studies do not detect evidence of negative employment effects. We re‐investigate this question using data from the 1994 to 2016 Current Population Survey and conclude that minimum wage increases reduced employment of less‐educated Hispanic immigrants, with estimated elasticities of around –0.1. However, we also find that the wage and employment effects of minimum wages on low‐skilled immigrants diminished over the last decade. This finding is consistent with more restrictive state immigration policies and the Great Recession inducing outmigration of low‐skilled immigrants, as well as immigrants moving into the informal sector. Finally, our results show that raising the minimum wage is an ineffective policy tool for reducing poverty among immigrants. 相似文献

Using U.S. firm level panel data we simultaneously assess the contributions to productivity of three potential sources of research and development spillovers: geographic, technological, and product market (“horizontal”). To do so, we construct new measures of geographic proximity based on the distribution of a firm's inventor locations as well as its headquarters. We find that geographic location is important for productivity, as are technology (but not product) spillovers, and that both intra and inter–regional (counties) spillovers matter. The geographic location of a firm's researchers is more important than its headquarters. These benefits may be the reason why local policy makers compete so hard for the location of local R&D labs and high tech workers. 相似文献

The implementation of smart meters in German households by 2032 is a major step in the transition towards an intelligent and connected energy system. Despite of federal legislation providing a structured plan for the nationwide smart meter rollout including basic product requirements, actors within the energy market have the opportunity to take an active part in shaping the market through appealing product offers and hence to create competitive advantage. This study identifies relevant features of smart meters from literature und business practice, and measures customer’s preferences for these features. Results indicate predominantly positive customer evaluations of smart meter features, amongst which the availability of consumption data, the installation price and rental charges as well as time variable tariffs contribute most to overall utility of smart meters. Finally, findings suggest targeting customers by defining strategies to address privacy concerns, to educate about saving potentials as well as to create differentiated pricing schemes. 相似文献

Research Summary: We propose that due to financial market pressures, managers are forward‐looking in their search and decision processes and focus on meeting performance targets set by the financial community. Using panel data on S&P 100 companies, we find that pressure felt by management to meet the analyst consensus earnings estimate influences the extent of corporate downsizing. Moreover, our results show that high levels of institutional investor stock ownership and CEO power attenuate managers’ sensitivity to financial market pressures, while high levels of analyst coverage increase their sensitivity. Managerial Summary: In this study we examine how financial market pressures influence managers’ downsizing decisions. We argue that investment analysts’ earnings estimates represent important performance targets to which managers aspire. If firms fail to meet analysts’ expectations, the stock price will suffer. This study shows that managers utilize corporate downsizing to address the potential shortfall between a firm's future performance and the analyst consensus earnings estimate. In addition, we find that managers’ concerns over meeting analysts’ earnings estimates are influenced by various contextual factors such as institutional investor stock ownership, CEO power, and high levels of analyst coverage. 相似文献

The Role of Ideas in Understanding Industrial Relations Policy Change in Liberal Market Economies 下载免费PDF全文
This paper analyzes the uneven processes underpinning industrial relations policy liberalization in New Zealand, Australia, the UK, and Ireland. Drawing upon 140 elite interviews and building upon ideational comparative political theories, the paper highlights the role of ideas in the policy change process. It identifies how particular ideas can be used to construct policy problems, how these ideas can gain legitimacy through battles with competing ideas, and how policy legacies can influence whether ideas take root. The findings from the comparative case analysis expose a critical difference between “positive legacies” and “negative legacies” to account for different liberalization trajectories. 相似文献

Replanning is often used to optimize results of an activity in an ever changing world. To address the challenge of preparing future engineers for success, a special course was created for all engineering freshmen of the Faculty of Engineering of the University of Porto, in Portugal. Presented as a case study, this special course underwent a careful replanning as a result of several years of experience in teaching practice alongside with a theoretical deepening in pedagogical and technological issues, under the aegis of the action-research methodology. Within the context of the case study course, the mentioned replanning was also based on a theoretical approach that clearly identifies teaching–learning-assessment methodologies that promote regulation from those that foster emancipation, using a specific instrument: a taxonomy of educational processes. The replanning was designed to globally boost results regarding the educational aims of the course such as furthering freshmen’s integration into work environment and preparing them for success by fostering transversal skills (needed for study and work). Technology is seen as a mean of education enrichment as well as a productivity tool. The introduced innovations include fun-but-educational activities, several types of assessment over time and specific technological tools which were critical for the educational impact/achievement of this course. Success is demonstrated by encouraging feedback from the stakeholders, high students’ classifications and a steady reduction in retention. It is advocated that large portions of the reasoning behind the replanning can be extrapolated to other courses. 相似文献

The Impact of an increasing share of RES-E on the Conventional Power Market — The Example of Germany
The intermittency of wind power has a decreasing effect on day-ahead spot prices. Data from Germany illustrate this effect
and explain the underlying relationships. This short-term price effect leads to an adaptation process in the conventional
generation capacity mix. In the long-run, a higher peak load plant share is required to cope with the increasing volatility
of the residual demand. The result is an adapted merit-order. This merit-order intersects with an increasingly volatile residual
demand curve and leads to a higher price volatility in the power market, which is going to trigger further adaptations. Therefore
this article concludes with a list of open research questions, which can be derived from the illustrated relationship. These
research questions should be investigated as soon as possible in order to induce the required adaptations in time. 相似文献

Adding to the corporate effect literature, we study the effect of owners on firm performance in a new context, that of venture capital firms (VCs) and the start‐up firms in which they invest. After discussing the effect that VC ownership can have on start‐ups, we estimate that start‐up‐specific, owner (VC), and year effects account for significant variance in performance (26.3 percent, 11.2 percent and 3.7 percent, respectively). The effects of industry and investment stage are not statistically different from zero. We also provide an analysis that separates the owner effect into two components: a selection component—which impacts investment—and a management component—which explains significant variance in performance. By examining the owner effect in a different institutionalized form of governance—that of the start‐up and its relationship to VC owners—our study also contributes to an understanding of the ‘ownership’ effect in the strategy literature more generally.
