Jeremy D. Foltz Bradford L. Barham Jean-Paul Chavas Kwansoo Kim 《Journal of Productivity Analysis》2012,37(2):171-186
This article investigates the determinants of efficiency and technological progress at US research universities. It relies
on a unique panel data set of multiple outputs and inputs from 92 universities covering the period 1981–1998. Over that time
span, US universities experienced large increases in industry funding and in academic patenting activity. In this context,
the directional distance function and a nonparametric representation of the underlying production technology are combined
to obtain estimates of productivity growth and technical efficiency. An econometric analysis is then presented to examine
the determinants of technical efficiency and the rate of technological progress. The results show how changes in funding sources
for US research universities affects research performance. 相似文献

The design and construction of the built environment requires explicitly addressing the risk-resilience tradeoff – too weak and the structure may fail, too strong and it will result in excess capacity, cost and embodied energy. This tradeoff is generally managed through the establishment of, and compliance with building standards and codes that often specify the exact methodology by which design parameters shall be calculated from environmental measurements of wind speeds, wave heights, flood levels and other environmental variables. Furthermore, these standards commonly legislate that historical data be used to calculate these design parameters. However, climate science has revealed that in some, if not many cases, these historical datasets may not be representative of future conditions and thus using historical data to develop design parameters for future long-lived infrastructure may increase the likelihood that the risk-resilience tradeoff becomes inadvertently skewed. Hence we now have a conundrum in that engineers are directed to design structures using standards that are based on time series on environmental parameters that we believe in some cases may be unrepresentative of the conditions which structures may face. 相似文献

Venture capital (VC) funds specializing in investing equity capital in minority-owned businesses have grown rapidly over the
past decade, fueled by the willingness of major institutional investors to support this traditionally neglected niche. We
investigate impacts of public pension funds upon the minority VC sector. These funds, providing over half of all capital invested
in minority VCs, selectively invest, seeking to fund only those VCs likely to generate high returns. Although they attempt
to pick the winners, our findings indicate that they have failed to do so. The influence of public pension funds upon the
minority VCs is nonetheless real, skewing investing away from traditional practices and toward those of the venture capital
mainstream. In the process, minority VCs funded by pension fund money invest in high-tech fields more than other minority-oriented
VC funds do. Further, they are less likely to fund minority-owned small firms, focusing increasingly upon firms owned by nonminority
Whites. Neither of these trends has resulted in increased returns. Rather, diverting minority-oriented VCs away from their
traditional mission of investing in minority firms operating in a broad range of industries has resulted in lower returns
over the years studied. 相似文献

Business-to-business firms are increasingly focusing on building long-term partnering relationships with key customers. Salespeople
are often responsible for managing these relationships. To be effective as relationship managers, salespeople need to be embedded
in both their firm’s and customers’ organizations. They need to have extensive knowledge of their customers’ business and
also know and be able to leverage their firm’s resources to develop offerings tailored to their customers’ needs. Their companies
and sales managers need to use different approaches to manage and support salespeople in this new role. In this paper, we
examine some issues affecting the interfaces between elements of the embedded sales force and suggest some directions for
future research and methods for examining these issues. 相似文献

This article examines the role of ex post labor supply in smoothing income in response to crop losses caused by large floods among riverine households in the Peruvian Amazon, where rich environmental endowments permit a variety of resource extractive activities and coping responses. The paper finds that households respond to crop losses primarily by intensifying fishing effort, not by relying on gathering of nontimber forest products, hunting, or asset liquidation. This ex post labor adjustment helps to smooth total income against small crop losses but less well against large crop losses. Both relatively nonpoor households with better fishing capital and poor young households with a physical labor advantage employ this natural insurance in rivers. 相似文献

In this study, an integrated model of return seasonality is developed and the hypothesis that seasonality is associated with changes in relative trading volume is examined. Return regularities associated with the turn of the month, the week of the month, and holiday closings are documented. Beyond these effects, neither the turn of the year nor the January effect is significant for large firms. Relative volume is shown to display calendar regularities similar to those in returns, and tests indicate a causal relationship flowing from volume to returns. 相似文献

Preliminary Evaluation of the HECM Reverse Mortgage Program 总被引:1,自引:0,他引:1
This paper describes and evaluates the Home Equity Conversion Mortgage (HECM) insurance demonstration, designed to encourage the development of private reverse mortgage programs by insuring lenders against the risks associated with new mortgage lending programs and with reverse mortgages in particular. The paper evaluates demand for the program by analyzing the attributes of participating borrowers, their properties and the types of payment options chosen. It also presents several observations regarding participation by the financial community in the HECM demonstration, required counseling and legal and regulatory issues that may hamper the growth and development of reverse mortgage programs in general.
The findings suggest strong demand for reverse mortgages among "house-rich, cash-poor" elderly homeowners, either to supplement inadequate current incomes or to provide a reserve against unexpected lump-sum expenses. The flexible design of the HECM program addresses a wide variety of borrower financial needs, even though it imposes higher costs on lenders and servicers. The continued growth of the program, however, is hindered by a shortage of qualified housing counselors in some areas, as well as by a variety of legal and regulatory barriers. 相似文献
