Research problems where the observed dependent variable is restricted to lie within an interval with massing of some of the observations at the limiting values of the interval are frequent in business research studies. This paper analyzes one such problem—that of lender response to a business loan application. The unique features of a regression model with a doubly limited dependent variable are explained and interpreted. Parameter estimation for such models is undertaken by maximum-likelihood techniques. In this paper maximum likelihood estimates are obtained for an empirical problem and compared with ordinary least-squares estimators. Results show substantial differences between least-squares and maximum-likelihood estimates, indicating a possibility for serious errors by using least-squares methods on models with a doubly limited dependent variable. 相似文献

This posttest-only experiment examined how source attribution and the personality characteristic of fatalism affect evaluate and behavioral intention responses to direct advocacy print advertisements. Two commercial sources, a noncommercial source, and no source were manipulated in an identical print advocacy ad. Regression analysis revealed that subjects exposed to the two commercial source treatments evaluated the ad more negatively than subjects exposed to the noncommercial and no source treatments. The commercial and trade association source treatments also produced a negative intent to respond to the advocated request. Fatalism was found to be significantly related to behavioral intention, but not the message evaluation. Overall, the results indicate that commercial sponsors should employ direct advocacy print advertisements with the knowledge that their commercial identification elicits critical and negative responses from uncommitted audience members. 相似文献

This study employs a customer interaction approach to examine how service organizations' strategic positioning relates to their human capital, and how the interaction between strategic positioning and human capital impacts organizational performance. Results from 234 service organizations in 96 different industries indicate very strong relationships between strategic positioning choices and human capital. We also find that certain combinations of strategic positioning and human capital result in superior performance. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

Constitutional choice for the control of water pollution 总被引:1,自引:1,他引:0
Before passage of the Clean Water Act, water pollution was controlled by the common law of nuisance and the law of water rights.
Had the common law not been superseded, it might have provided more ecologically sound pollution control than has occurred
under the command-and-control statutory regime. The Clean Water Act imposes mechanical definitions and is subject to political
interference. In contrast, the principle of the common law lies in its evolutionary and competitive nature, which is consistent
with the market process.
Meiners thanks the Political Economy Research Center of Bozeman, Montana for support during his visit in 1992. We thank Terry
Anderson, Robert Natelson, Jane Shaw and Richard Stroup for helpful comments. We owe a large intellectual debt to Bob Staaf,
who made us think about the relationship between competitive markets and the common law. 相似文献
