The role of health insurance in labor supply decisions of divorced females

Labor economics literature provides evidence that marital dissolution induces an increase in labor supply of females. This paper explores an explanation for this finding: Marital separation might place wives at risk of losing health insurance or increase the need for expanded health coverage. Thus, wives must increase their labor supply in order to qualify for health benefits. Using data from the National Longitudinal Survey of Youth, results confirm that marital dissolution is associated with increased female labor supply. However, this effect is mostly concentrated among women who were not previously enrolled in their husbands’ health insurance plans. For wives who were dependent on their husbands for coverage, continuing coverage laws appear to mitigate the effect of marital dissolution on female labor supply.     

Employee benefits: Literature review and emerging issues

Many have noted the lack of human resource management research on employee benefits, which is surprising because employer-sponsored benefits are a primary concern of executives and employees alike. Moreover, of special interest to scholars, benefits provide a unique opportunity to examine fundamental theoretical and empirical questions about employee behavior and contemporary employment relationships. This paper provides a foundation for such research by providing an overview of the context from which U.S. employer-provided benefit programs evolved and the contemporary state of benefits research in human resource management. Propositions related to primary employee benefit research are provided.     

Household search and health insurance coverage

Health insurance in the United States is typically acquired through an employer-sponsored program. Often employees offered employer-provided health insurance have the option to extend coverage to their spouse and dependents. We investigate the implications of the “publicness” of health insurance coverage for the labor market careers of spouses. The theoretical innovations in the paper are to extend the standard partial–partial equilibrium labor market search model to a multiple searcher setting with the inclusion of multi-attribute job offers, with some of the attributes treated as public goods within the household. The model is estimated using data from the Survey of Income and Program Participation (SIPP) using a Method of Simulated Moments (MSM) estimator. We demonstrate how previous estimates of the marginal willingness to pay (MWP) for health insurance based on cross-sectional linear regression estimators may be seriously biased due to the presence of dynamic selection effects and misspecification of the decision-making unit.     

Employee representation on health and safety and European Works Councils

Three hundred and eighty‐six voluntary agreements on European Works Councils are examined for material that might support their role in transnational consultation on health and safety in Europe. A significant percentage do indeed support the potential development of consultation on health and safety at this level, both substantively and with representation on health and safety at enterprise level. However the support is uneven and in a number of areas it is relatively weak.     

Rationality in supplier selection decisions: The effect of the buyer's national task environment

Our study sheds light on two fundamental questions in supply management: First, does adherence to highly rational decision processes help buyers make better supplier selection decisions? Second, is the influence of procedural rationality on decision effectiveness moderated by buyers’ (differently dynamic) task environments? We empirically test these questions using a sample of 150 supplier selection decisions taken in China and 150 decisions taken in Germany, countries that expose buyers to dynamic decision environments and stable decision environments, respectively. Our findings suggest that the influence of decision process rationality is stable across decision makers’ task environments. Both in China and in Germany, such process rationality is positively related with higher decision quality, and no significant differences in relationship strengths emerge between the two country samples.     

Integrated manufacturing/distribution planning decisions with multiple imprecise goals in an uncertain environment

This work presents a possibilistic linear programming (PLP) method for solving the integrated manufacturing/distribution planning decision (MDPD) problems with multiple imprecise goals in supply chains under an uncertain environment. The imprecise PLP model designed here aims to simultaneously minimize total net costs and total delivery time with reference to available supply, capacities, labor levels, quota flexibility and cost budget constraints at each source, as well as forecast demand and warehouse space at each destination. The proposed method achieves greater computational efficiency by employing the simplified triangular distribution to represent imprecise numbers. An industrial case is used to demonstrate the feasibility of applying the proposed method to a real MDPD problem. Overall, the proposed PLP method provides a practical means of solving the multi-objective MDPD problems in an uncertain environment, and can effectively improve manufacturer/ distributor relationships in a supply chain.     

Requirements planning systems in the health care environment

An important problem confronting health care administration is cost containment in hospitals. Much of the current high costs can be traced directly to outdated procedures in materials management leading to waste, excessive inventory and unnecessary obsolescence of expensive short shelf life items. In this paper, we illustrate how a modern requirements planning system for surgical supplies was developed for a private hospital in Houston and used to effectively hold inventory levels to the minimum required to support a detailed schedule of surgical procedures. We also discuss some specific problems involved in the transfer of manufacturing technology to the hospital setting.

Breadth-of-impact frontier: How firm-level decisions and selection environment dynamics generate boundary-spanning inventions

In this paper, we provide an ex-ante explanation for why some technologies such as James Watt’s steam engine move successfully across broad technological fields, while other technologies do not. Using a sample of VC-backed biotechnology firms, we examine firm knowledge exploration choices along three dimensions—the decision to build from technologies across broad fields, the decision to explore application domains that are new to the firm, and the decision to mix these two options at the same time. We argue that firm-level invention decisions find differing responses when received by the selection environment. We find evidence of a “breadth-of-impact frontier” for technologies, wherein the choice of whether a firm should enter into a new application domain than those of the past should be informed by the degree to which the technology is citing prior work narrowly or broadly. The findings suggest that the belief that broad sourcing diversity will always result in greater citation diversity requires some caveats. The results contribute to the understanding of not only how entrepreneurial firms evolve but also how individual firms contribute to collective progress.     

The effect of unemployment benefits on re-employment rates: Evidence from the Finnish unemployment insurance reform

In January 2003, the unemployment benefits in Finland were increased for workers with long employment histories. The average benefit increase was 15% for the first 150 days of the unemployment spell. At the same time severance pay system was abolished. In this paper we evaluate the effect of the change in the benefit structure on the duration of unemployment by comparing the changes in the re-employment hazard profiles among the unemployed who were affected by the reform to the changes in a comparison group whose benefit structure remained unchanged. We find that the change in the benefit structure reduced the re-employment hazards by on average 17%. The effect is largest at the beginning of the unemployment spell and disappears after the eligibility period for the increased benefits expires.
