This study examines derivatives use of foreign exchange, interest rate, and commodities risk by nonfinancial firms across multiple industries, using data from 1995 to 2001. This work considers the interaction of a firm's risk exposures, derivatives use, and real operations simultaneously, and considers how these factors change over time using a consistent database. Hedging with derivatives is only signi.cantly related to commodity risk exposure during most years of the study, and to a more limited degree to interest rate exposure. Further, a strong correlation was found between risk exposures for some years using a new technique, suggesting that univariate modeling is not always appropriate. The implications are that hedging with derivatives is not always important to a firm's rate of return and is linked to other nonfinancial and economic factors. © 2007 Wiley Periodicals, Inc.

This study examines the effect of life expectancy on fertility, education, and labor force participation. Using birth and sibling histories from the Demographic Health Surveys conducted in sub‐Saharan Africa, I construct a time series of age‐specific birth rates and mortality rates at the country‐region level. I use these data to test the implications of a general equilibrium model linking life expectancy to fertility, human capital, and labor supply. My results suggest that increases in life expectancy reduce fertility, increase education, and increase labor force participation. Overall, my empirical results suggest that in sub‐Saharan Africa, increases in life expectancy will have a positive impact on growth through fertility, education, and labor supply but that the effect will be small. My results also rule out the possibility that recent shocks to adult mortality in high HIV prevalence countries will reduce fertility, increase labor productivity, and lead to faster growth. 相似文献

The employee-organization relationship, organizational citizenship behaviors, and superior service quality 总被引:1,自引:0,他引:1
This study proposes a model of customer-contact service employee management that examines organizational citizenship behaviors as critical links between aspects of the employee-organization relationship (perceived organizational support, organizational identification) and customers’ perceptions of service quality. In addition, it investigates the role of job autonomy in providing the necessary behavioral discretion for employees to be able to perform citizenship behaviors. The hypothesized model was partially supported. Theoretical and managerial implications are explored. 相似文献

The classic Sargent–Wallace–Lucas (SWL) rational expectations-flexible price model is usually interpreted as implying “policy ineffectiveness”: systematic monetary rules cannot affect the distribution of real output. A contrary but not widely-appreciated result of Dotsey and King suggests that there exist “prospective feedback” rules (future money depending systematically on current but as yet unobserved information) which improve output distribution by means of improving agents’ ability to perceive relative prices.We show the Dotsey–King proposition in fact to be a colossal understatement: prospective feedback rules applied vigorously enough (and even “contemporaneous feedback” rules based on current interest rates, provided at least one prospective feedback is active) can in the limit drive price-perception errors to zero. This is not to say such a policy would be desirable. Feedback parameter combinations that reduce current price level misperception tend to produce high forecast error variances with respect to future prices, with attendant loss in capital market efficiency. Whatever the desirable frontier among these different social cost-producing variables, feedback parameters will in general be needed in order to get on the frontier as well as to move along it. Monetary policy clearly produces social gain even in a version of this model which contains no elements of price “friction,” inefficient use of available information, or asymmetry in information as between the government and the public. 相似文献

We combine records of Atlanta Housing Authority (AHA) clients, Georgia Department of Labor (DOL) employment records, and neighborhood characteristics to analyze the causal effect of an exogenous move out of public housing on the employment of public housing residents. The exogenous move was caused by a HOPE VI or HOPE VI‐like project in Atlanta. We find that such an exogenous move has a positive and statistically significant effect on the probability of employment for those residents who moved relative to other public housing tenants. We also compare the change in employment of those whose exogenous move was to another public housing unit to those who took a housing voucher. We also compare the change in the probability of employment associated with an exogenous move and a voluntary move and find that both types of moves are associated with a greater probability of employment as compared to those who did not move. 相似文献

Top management team diversity and innovativeness: The moderating role of interfunctional coordination 总被引:1,自引:0,他引:1
Top management team (TMT) diversity has received considerable attention in the academic literature as well as in the corporate arena. Our paper develops a contingent model on how top management team diversity acts as a form of human capital and can have a positive effect on innovativeness when it is effectively leveraged with favorable social capital. Our theoretical underpinning rests on the argument that greater interfunctional coordination is a source of internal social capital, which mitigates the costs while at the same time highlights the benefits associated with TMT diversity. By testing our model with TMT executives, the results generally supported our hypothesis in that the effect of TMT diversity on innovativeness was positive as interfunctional coordination increased. Implications for marketing theory and practice are discussed. 相似文献

This article tests the performance of a wide variety of well-known continuous time models—with particular emphasis on the Black, Derman, and Toy (1990; henceforth BDT) term structure model—in capturing the stochastic behavior of the short term interest rate volatility. Many popular interest rate models are nested within a more flexible time-varying BDT framework that allows us to compare the models and find the proper specification of the dynamics of short rates. The empirical results indicate that the equilibrium models that do not allow the drift and diffusion parameters to vary over time and parameterize the volatility only as a function of interest rate levels overemphasize the sensitivity of volatility to the level of interest rate and fail to model adequately the serial correlation in conditional variances. On the other hand, the GARCH-based arbitrage-free models with time-dependent parameters in the drift and diffusion functions define the volatility only as a function of unexpected information shocks and fail to capture adequately the relationship between interest rate levels and volatility. This study shows that the most successful models in capturing the dynamics of short term interest rates are those that introduce time-dependent parameters to the short rate process and define the conditional volatility as a function of both the interest rate levels and the last period's unexpected news. © 1999 John Wiley & Sons, Inc.

Employing a regression discontinuity (RD) approach on gubernatorial elections in the United States over the last three decades, this paper investigates the causal effects of governors' party affiliation (Democrat versus Republican) on unionization of workers, and unionized workers' working hours and earnings. Surprisingly, we find no significant impact from the party affiliation of governors on union membership and union workers' labor‐market outcomes. 相似文献

ABSTRACTWater has been seen as a healing source of life for centuries. Even the placebo effect of thermal therapies increases consumers’ well-being. Especially with easy traveling options demand for thermal therapies are on the rise. Users of thermal therapies are mostly composed of seniors. Even though age groups in the senior market have heterogeneous needs, managers assume them to be homogenous. Measuring thermal tourism demand by the length of stay, this study analyzed the determinants affecting the length of stay of older thermal tourists. The length of stay is predicted to have been affected by age, purchasing power, physical distance, and seasonal preferences. Even though all of the above have an effect on the length of stay, we find that age is the main determinant deciding the duration. These results may serve as a starting point for policymakers and tourism managers to tailor strategies to increase income streams associated with length of stay. 相似文献

For the period 1930, 1931, 1937–1987, the Scheffe’s test provides evidence of regionalization in Moody’s ratings of state
government general obligation bonds. Sub-period analysis indicates a reduction in the extent of regionalization over time.
Findings suggest this may be due to a change in the criteria used in rating such bonds. However, further study is necessary
on this topic. The results also suggest that further study is necessary on the question of why two political-economic variables
show no regionalization and the meaning of this finding to bond ratings. 相似文献
