The purpose of this paper is to analyze determinants of the decision to self-report health impairments that limit or prevent work. Its particular focus is on joint reporting behavior by married couples, with a view toward potential interdependence of spouses' reporting decisions. The model is based on a large sample of married couples taken from the 1990 Public Use Microdata Sample of the U.S. Census. Empirical analysis is based on a simultaneous probit model of spouses' reports. Results of the analysis show evidence of an association between spouses' reports, after controlling for important background variables. The extent of association appears to be more pronounced among low earners and among older wives. 相似文献

Illicit drug use has declined among the U.S. adult population, but national surveys show the majority of illicit drug users are employed. Concern about workplace productivity, absenteeism, and safety has led many employers to establish employee assistance and drug testing programs. Given the sharp interest in workplace interventions, more information is needed about the relationships between drug use and labor market status. This study estimated the probability of employment and labor force participation for different types of drug users using nationally representative data from the 1997 National Household Survey on Drug Abuse. Results strongly indicated that chronic drug use was significantly related (negative) to employment for both genders and labor force participation for males. Furthermore, nonchronic drug use was not significantly related to employment or labor force participation. These findings suggest that workplace policies for illicit drug use should consider chronic or problem drug users apart from light or casual users. 相似文献

This paper studies the use of patent statistics in identifying four aspects of technological structure, namely, the potential knowledge pool, cumulativeness, inter-firm homogeneity in technology levels, and the scope of innovations. The firms are sampled from the chemical (CHEM), the computer (COM) and the electrical and electronic (EE) industries worldwide. Using the proxies defined, we find that (i) the contributions of intra-industry spillover are low, at 12%, 10%, and 9% for the three industries respectively; (ii) they can internalize 15%, 19% and 13% of their previous research efforts respectively; and (iii) a positive relationship between knowledge spillover and technology overlap, and between scope of innovation and number of patents being cited in future. 相似文献

The paper aims to identify those factors that cause changes in the speed and strength of the international transmission of output shocks from the USA to specified European economies. These factors are identified through the use of generalized impulse response functions conditioned on histories defined by an abrupt transition VAR. The chosen transition variables comprise changes in exchange rates, financial prices, international capital flows, trade links and monetary policy instruments. Besides the identification of asymmetric responses, the proposed model is useful in analyzing the strong effect of the recent US recession on the European economies and changes in business cycle synchronization over time.

This study challenges the generally accepted managerial decision to accept a quantity discount if total, perperiod inventory and acquisition costs are reduced. In this paper, the economic order quantity model is reformulated within an explicit wealth maximization framework, and the reformulated model is then utilized to analyze inventory decisions when volume discounts are available. The results of the study indicate that the traditional method of analyszing volume discount opportunities may invoke wealth decreasing decisions. 相似文献
