Several findings reported by researchers working in quite different areas suggest that individuals may be able to receive advertising in a way which is very different from the advertising communication process. Here, some of these findings are presented. They derive from studies of picture perception, of mere exposure, of brain lateralization, of emotion formation, of attention processes, and from new approaches to content analysis. Finally, the need for a revised view on how advertising works is emphasized.  相似文献

Conventional analyses of the credit rationing problem seek to explain that problem within the context of classic demand analysis. In this paper we demonstrate that it is generally inappropriate to apply the notion of classic demand to credit markets, consequently, conventional notions of credit rationing must be rejected. In providing a new definition of credit rationing we also establish the previously rejected characterized by credit rationing.  相似文献

This study investigates the relationship between environmental performance and productive efficiency in the United States electric utility industry before and after the 1990 Clean Air Act Amendments. Using Data Envelopment Analysis (DEA), cross-sectional examinations reveal lower polluting plants are more efficient than higher polluting plants. Longitudinal analyses indicate plants can simultaneously reduce pollution and increase relative efficiency. Collectively, these results are evidence that proactive environmental management can reduce environmental costs and thus, lends support for adopting an environmental cost management system.  相似文献

Objective: To assess end-of-life (EOL) total healthcare costs and resource utilization during the last 6 months of claims follow-up among patients with metastatic breast cancer (MBC) who received systemic anti-neoplastic therapy.

Methods: Newly diagnosed females with MBC initiating treatment January 1, 2003–June 30, 2011 were identified in a large commercial claims database. Two cohorts were defined based on a proxy measure for EOL 1 month prior to the end of last recorded follow-up within the study period: patients who were assumed dead at end of claims follow-up (EOL cohort) and patients who were alive (no-end-of-life [NEOL] cohort). Proxy measures for EOL were obtained from published literature and clinical expert opinion. Cost and resource utilization were evaluated for the 6 months prior to end of claims follow-up. Baseline variables, resource utilization, and costs were compared between cohorts with univariate statistical tests. Adjusted relative risks were calculated for resource utilization measures. A covariate-adjusted generalized linear model evaluated 6-month total healthcare costs.

Results: Of the 3,878 females included, 18.5% (n?=?718) met the criteria for EOL. Mean observational time (MBC onset to end of claims follow-up) was shorter for the EOL cohort (EOL, 32 months vs NEOL, 35 months; p?p?2 times higher in the EOL cohort (p?Conclusions: Potential EOL presented a greater economic burden in the 6 months prior to death. EOL month-to-month costs increased precipitously in the last 2 months of life and were driven by acute inpatient care.  相似文献

We develop new methods for representing the asset-pricing implications of stochastic general equilibrium models. We provide asset-pricing counterparts to impulse response functions and the resulting dynamic value decompositions (DVDs). These methods quantify the exposures of macroeconomic cash flows to shocks over alternative investment horizons and the corresponding prices or investors’ compensations. We extend the continuous-time methods developed in Hansen and Scheinkman (2012) and Borovi?ka et al. (2011) by constructing discrete-time, state-dependent, shock-exposure and shock-price elasticities as functions of the investment horizon. Our methods are applicable to economic models that are nonlinear, including models with stochastic volatility.  相似文献

I present proofs for the consistency of generalized method of moments (GMM) estimators presented in Hansen (1982). Some basic approximation results provide the groundwork for the analysis of a class of such estimators. Using these results, I establish the large sample convergence of GMM estimators under alternative restrictions on the estimation problem.  相似文献

Professors Hansen and Kelley suggest practical guidelines for implementing course evaluation systems, drawing upon their experience at the University of Wisconsin. They develop a model to conceptualize course evaluations in the context of the professor's decision-making framework, focusing upon the allocation of time between teaching and research. Costs and benefits associated with collecting evaluations are considered, and ways of minimizing the former and maximizing the latter are suggested.  相似文献

This paper expands the standard analysis of female labor supply to permit preference heterogeneity by using a finite mixture model. Using the extended model, we obtain theory consistent results whereas a traditional model produces a negative substitution effect. We use our model to illustrate the labor supply effects of a tax reform, corresponding to 1983–1992 changes in the Swedish income-tax schedule. The results shows an expected reduction in tax revenues of about 17%. Finally, we use Monte Carlo simulations and show that our proposed mixture model is robust towards different misspecifications.
