Medical Malpractice Liability and Physician Migration

This paper uses national data on individual physicians and two control groups to provide evidence on the extent to which each of five medical malpractice reforms impacts the decision to move one's medical practice to another state. We find robust evidence that states that have implemented noneconomic damage caps experience less out-migration of physicians than states that do not have these reforms. In addition, we find some evidence that joint and several liability reforms and patient compensation funds also impact the migration decisions of physicians.     

Strategic planning of complex economic systems ∗

A major drawback of conventional models of the behavior of economic systems (and derived tools for policy intervention) is that the desire for tractability leads generally to a high degree of abstraction from reality. This article suggests an alternative, and arguably complementary, approach which engages specifically with economic complexity. The technique used is one of interactive spatial modelling over long time periods where the principle economic agents base decisions on incomplete heuristic information. For illustrative purposes the model has been calibrated on the basis of Senegalese data for 1981–91 and broad generic equations presented. The article argues that such a methodological approach holds out considerable advantages for strategic planning of sustainable economic systems. In particular it permits the direct engagement of noneconomic disciplines and client stakeholders in the planning process.     

Understanding contemporary marketing: Development of a classification scheme

The term Relationship Marketing has been used in a multitude of ways to describe and define marketing in the contemporary environment. This has led to the term being loosely defined and applied in the literature, resulting in frustration for both researchers and practitioners. Therefore, a classification scheme is developed from analysis of the extant literature, and used to systematically examine the meaning of marketing across twelve dimensions which reflect issues related to marketing practice. From this scheme, the authors identify two ‘perspectives’ of marketing, which encompass four distinguishable ‘types’ of marketing. Implications for future research in the area are discussed.

Abstract

We consider an optimal dynamic control problem for an insurance company with opportunities of proportional reinsurance and investment. The company can purchase proportional reinsurance to reduce its risk level and invest its surplus in a financial market that has a Black-Scholes risky asset and a risk-free asset. When investing in the risk-free asset, three practical borrowing constraints are studied individually: (B1) the borrowing rate is higher than lending (saving) rate, (B2) the dollar amount borrowed is no more than K > 0, and (B3) the proportion of the borrowed amount to the surplus level is no more than k > 0. Under each of the constraints, the objective is to minimize the probability of ruin. Classical stochastic control theory is applied to solve the problem. Specifically, the minimal ruin probability functions are obtained in closed form by solving Hamilton-Jacobi-Bellman (HJB) equations, and their associated optimal reinsurance-investment policies are found by verification techniques.     

The effects of role strain on the consumer decision process for groceries in single-parent households

Single-parent families are becoming a larger part of American society. But what is known about their decision-making processes? Role strain is of particular interest when studying single parents because of their need to serve multiple family roles otherwise carried out by dual-parent families. In this study, the consumer decision process for single parents is empirically examined in the context of grocery shopping. Role strain was found to have a significant effect on problem recognition style and reactive shopping behaviors. Advertising positively influenced proactive shopping behaviors and had a negative relationship with reactive shopping behaviors. Implications for food retailers are provided.     

Running on the spot? A review of twenty years of research on the management of human resources in comparative and international perspective

Research using a comparative and international perspective on the management of human resources is examined, drawing on articles published in leading human resource management, management/organizational behaviour and related social science journals between 1977 and 1997. In total a little under 2 per cent of the articles under review focused on the management of human resources in a comparative and international perspective. The largest group of these articles was comparative in nature (44 per cent), followed by those with an international perspective (35 per cent). A smaller number adopted a combined approach (17 per cent) and a few were separately classified as foreign national studies (4 per cent). Over time, there has been some progress made in terms of the number of articles published and the scope of topics covered. However, many of the articles displayed similar shortcomings to those noted in earlier reviews of cross-national management/organization studies: in particular, an over-reliance on a small number of primarily Anglo-Saxon countries, a lack of a longitudinal perspective, a loose specification of culture, an ethnocentric bias and a frequent failure to explain observed differences and similarities.     

INVESTMENT PERFORMANCE OF COMMON STOCKS IN RELATION TO INSIDER OWNERSHIP

In this paper, the authors empirically examine whether corporations with high degrees of insider ownership enjoy superior returns compared with firms with more diffuse ownership. In addition, the authors evaluate the effects of insider ownership on security returns in relations to the well-known effects of size and earnings yield (or price-earnings) ratios. Results indicate that, in addition to Basu's price-earnings effect, insider ownership is a new statistically significant variable that is associated with abnormal returns. This return anomaly might occur because the market pays an inadequate price for top managements' equity ownership, a firm-specific fundamental variable that has a theoretical foundation in agency theory.
