We investigate minority access to small-business loans using a probit model of loan application denial that recognizes two loan types (line-of-credit loans and non-line-of-credit loans) made by two lender types (commercial banks and nonbank financial institutions). We estimate our model on data from the 1998 Survey of Small Business Finances. We find evidence consistent with minority equal access to bank credit lines and nonbank non-line-of-credit loans in highly competitive loan markets; in less competitive markets we find evidence consistent with unequal access to these loans. We also find evidence consistent with unequal minority access to bank non-line-of-credit loans, regardless of loan market competitiveness. Our findings differ from previous research which treats small-business loans as a homogenous product and finds evidence consistent with unequal minority access to small-business loans generally. We argue that the existence of multiple small-business lending technologies and loan specialization by lenders account for our findings and demonstrate the need to treat small-business loans as a heterogeneous product when investigating equal access to small-business credit.  相似文献

Data from the 1993 Agricultural Resource Management Study were used to examine the impact of technology adoption on production performance of a sample of dairy farms. Findings showed that the adoption of a capital- or a management-intense technology would measurably lower the likelihood of a farmer being in the lowest quartile of production performance. The economic costs of milk production by the top-performance group were estimated to be 53% lower than those by the low-performance group, providing evidence of the importance of improved production practices to the viability of many dairy operations.  相似文献

The determinants of the long run equilibrium unemployment rate are modelled through a cointegrating regression. The residual term, which represents the error correction mechanism, is used in the testing of a general dynamic model to obtain a simplified representation of the data generation process over the period 1968(2)–1989(2). The long period equilibrium unemployment rate, which is I(1), is shown to be related to the rate of capacity utilization, a structural change variable and the rate of capacity growth. Steady state rates of unemployment are calculated which are based on different assumptions about the magnitudes of the independent variables. In contrast to the other two variables, changes in the rate of capacity utilization are shown to have only modest effects on the steady state unemployment rate. The Okun coefficient is inversely related to the steady state unemployment rate, which accords with intuition. The statistically significant decline in the trend growth rate of non-farm GDP in the 1970s explains, in part, the apparent instability of the Okun's law relationship which is revealed in recent studies. These studies can be criticised for their conometric methodologies.  相似文献

Much of the debate around the spatial development initiatives (SDIs) in South Africa is based on economic theory. To add the community perspective, an evaluation of local economic development on the Wild Coast followed a baseline in 1997 with comparable surveys in 2000 and 2004. Apart from an increase in access to piped water and a reduction in unofficial payments for health services, there was little community evidence of development over this period. Residents reported decreasing knowledge of the SDI and there was no increase in numbers considering small business ownership. In the investment-intensive ‘anchor’ areas, as in the SDI as a whole, there was no significant increase in employment and more households received remitted incomes from migrant workers. In an SDI for small businesses in tourism and agriculture, there was a dramatic fall-off in food production. No more households had loans in 2004 than in 1997, but more were taking loans from loan sharks. Other spatial planning initiatives might learn from the Wild Coast, not least through the perspectives gained from community-based impact assessments.  相似文献

State Medicaid home- and community-based waiver programs for persons with AIDS (PWAs) were implemented with the expectation that PWAs would use these services in lieu of more expensive hospital-based care. If so, Medicaid spending per PWA should decline, and program costs fall. We analyze Florida Medicaid claims data for PWAs from December 1995 through December 1997 to determine how participation in the waiver program affects the use of inpatient services, the receipt of antiretroviral combination therapies (available to Medicaid recipients throughout the study period), monthly expenditures, and survival of PWAs. We find that waiver participants are more likely to receive combination therapies but less likely to use hospital-based care than nonparticipants; white men and sicker patients are more likely to join the waiver program than other eligible PWAs; monthly expenditures for waiver participants are 52% lower than for nonparticipants; and waiver participation does not affect survival.  相似文献

In many industries, one important method of diffusion is through employee mobility: many of the entering firms are started by employees from incumbent firms using some of their former employer's technological know‐how. This article explores the effect of incorporating this mechanism in a general industry framework by allowing employees to imitate their employers' know‐how. The equilibrium is Pareto optimal because the employees “pay” for the possibility of learning their employers' know‐how. The model's implications are consistent with data from the rigid disk drive industry. These implications concern the effects of know‐how on firm formation and survival.  相似文献

This paper demonstrates the existence of bidirectional relationships between interfirm collaboration and business sales. Controlling for factors that influence whether firms form collaborative relationships, the analysis shows that entry and post‐entry collaboration often contribute to superior performance, which in turn attracts more partners. However, the performance influences vary across types of collaborators and collaborations, with differences among entrant and incumbent partners, between marketing and R&D partnerships, by partner size, and across time. The empirical analysis examines businesses that operated in the U.S. hospital software systems industry between 1961 and 1991. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

This article stresses the need for today's multinational firms to adopt their own political risk‐assessment and risk‐mitigation strategies. A comparative study of the energy, financial, and automobile sectors illustrates the need for all companies in these sectors to undertake comprehensive risk‐assessment strategies. Risk‐assessment models established by leading multinationals like British Petroleum, Bank of America, and General Motors are examined as examples that other companies in these sectors can build upon. The consistent micropolitical risk variables then lead to a proposed practical framework for examining sector‐specific micropolitical risk. © 2006 Wiley Periodicals, Inc.  相似文献

Although annuities are a theoretically appealing way to manage longevity risk, in the real world relatively few consumers purchase them at retirement. To counteract the possibility of retirees outliving their assets, Singapore's Central Provident Fund, a national defined contribution pension scheme, has recently mandated annuitization of workers’ retirement assets. More significantly, the government has entered the insurance market as a public‐sector provider for such annuities. This article evaluates the money's worth of life annuities and discusses the impact of the government mandate and its role as an annuity provider on the insurance market.  相似文献
