Empirical Tests of the Proxy Hypothesis

The proxy hypothesis states that the negative relationship between inflation and stock returns is spurious and really only proxies for the positive relationship between stock returns and real variables. Previous testes of the proxy hypothesis have used actual values instead of forecasted values for the real activity variable. Using only forecasted variables, our results do not support the proxy hypothesis.

An analysis of the cost of providing ancillary services to skilled nursing facility patients in New York State

Currently, nursing homes can arrange for the provision of ancillary services either by providing the services directly, purchasing the services through contracts and fees, or by outside billings, in which the services are supplied by other providers who then bill Medicaid directly. Frequently, some combination of these three modes of provision is used for each ancillary service. The purpose of this study is to explore ancillary costs in a sample of nursing homes and to determine, to the extent possible, the most cost-efficient means of providing selected ancillary services (physical therapy, radiology and medical staff services). Prior to examining the impact of the mode of provision on cost levels, other facility and patient characteristics that might justifiably affect costs are identified and adjusted for. The results demonstrate that outside billing or purchasing services can be much less expensive than providing the services directly. It is suggested that all ancillary services (outside billings as well as services provided directly through contracts and fees) be included when facility-to-facility cost comparisons are made. This approach should serve as an incentive for nursing homes to seek the most cost-efficient means of providing ancillary services.     

Is the FHA Creating Sustainable Homeownership?

We produce first estimates of the sustainability of homeownership for recent Federal Housing Administration (FHA) borrowers. Unfortunately, the FHA does not produce its own statistics on sustainability. Neither does it permit researchers access to its data on internal refinances. This imposes significant barriers to entry for researchers who wish to track FHA borrower performance over time. We carefully construct the required tracking data to overcome this barrier. We forecast that no more than 75% of the 2007–2009 vintages of FHA borrowers will be able to successfully exit the FHA system. Our work raises questions about FHA's role, its accounting and its accountability.     

COMPETITION POLICY AND CARTEL SIZE

This article examines endogenous cartel formation in the presence of a competition authority. Competition policy is shown to make the most inclusive stable cartels less inclusive. In particular, small firms that might have been cartel members in the absence of a competition authority are no longer members. Regarding the least inclusive stable cartels, competition policy can either decrease or increase their size and, in the latter case, the collusive price can rise.     

Removing the contextual lens: A multinational, multi-setting comparison of service evaluation models

Four service evaluation models are identified from the literature that are commonly offered to depict the relationships amongst the primary service evaluation constructs of sacrifice, service quality, service value, satisfaction, and behavioral intentions. We comparatively test the models using samples of service consumers in Australia, Hong Kong, Morocco, the Netherlands, and the United States, as well as across varied temporal and service settings. The results of the comparative analyses reveal that one conceptualization, the “comprehensive” model, best captures the identified relationships. This model is the best fitting across all countries and settings, which indicates it has the greatest external validity. These findings are discussed relative to the limitations associated with the use of less generalizable models.     

Differences in consumer perceptions of similarity and dissimilarity

Researchers have usually treated similarity ratings as the simple inverse of dissimilarity ratings. Tversky's theory of perception of similarity and dissimilarity (1977), however, explicitly recognizes that the attributes used in the perception of similarity and the attributes used in the perception of dissimilarity are decidedly different. In fact, the weights assigned to common and distinctive features changes according to the task at hand (i.e., when similarity is to be rated the common features are weighted more, and when dissimilarity is to be rated the distinctive features are weighted more). This study demonstrates these differences in a judgment task of rating similarity and dissimilarity on the basis of data that is external to the subjects.     

Supervising the Unethical Selling Behavior of Top Sales Performers: Assessing the Impact of Social Desirability Bias

This study measures social desirability bias (SD bias) by comparing the level of discipline sales managers believe they would administer when supervising unethical selling behavior with the level of discipline they perceive other sales managers would select. Results indicate the presence of SD bias; the sales manager respondents consistently claimed that they would be stricter while their peers would be more lenient. Using an analytical technique that takes social desirability bias into account, it appears that sales managers use of discipline is affected by the sales performance of the salesperson being disciplined resulting in more lenient discipline for top sales performers. In addition, the more lenient treatment for top sales performers persists even when there is a pattern of a prior ethical infraction and the existence of an explicit organizational policy proscribing the act in question. Sales managers believe that, like themselves, others would be stricter when an unethical act is committed for the second time but not as strict as they personally would be. A within-subjects interaction effect indicates more SD bias under the condition of the unethical act being committed for the second time.
