Incorporating Price and Replacement Purchases in New Product Diffusion Models for Consumer Durables*

The article presents theoretical and empirical research findings which incorporate price and replacement purchases in new product diffusion models. On the theoretical side, this paper characterizes, qualitatively, optimum pricing policies for new products. Possible entry of rivals is not considered, but repeat sales, cost learning dynamics and discounting of future profit streams are allowed. Theoretical research findings suggest that the inclusion of repeat purchases in the diffusion model significantly changes the derived optimal pricing policy even if replacements were not price dependent. On the empirical side, alternative first purchase and repeat purchase models have been estimated and compared using nonlinear procedures. The diffusion data analyzed is related to nine consumer durables. Empirical research findings suggest that, for the considered product categories, diffusion is basically an imitative process, price can affect first and replacement purchases, and unit production cost is a decreasing function of cumulative first purchases. Managerial implications of the research findings are also discussed.     

Structural Validation and Multiple Group Assessment of the Short Internalized Homonegativity Scale in Homosexual and Bisexual Men in 38 European Countries: Results From the European MSM Internet Survey

Internalized homonegativity (IH) is the internalization of negative attitudes and assumptions about homosexual people by homosexual people themselves. To measure IH, Smolenski, Diamond, Ross, and Rosser (2010) and Ross, Rosser, and Smolenski (2010) revised the Reactions to Homosexuality Scale (RHS) to develop the Short Internalized Homonegativity Scale (SIHS) with eight items. Using the European Men Who Have Sex With Men Internet Survey (EMIS) data, with an analytic sample of 130,718 gay and bisexual men in 38 European countries, we confirmed the validity of the SIHS scale in both training and validation data, in strata of Ross, Berg, et al.’s (2013) three “homosexual discrimination” country clusters, of age, and of education level. However, the performance was less adequate in comparison of gay versus bisexually identified individuals. The latent SIHS structure contains only minor variations across these three strata. The seven-item scale performed as well as the eight-item scale. The SIHS is a promising candidate for standard IH measures, which is invariant across cultural, age, and educational strata.     

The Present Retirement Crisis and How Social Workers Can Respond

ABSTRACT

Research on Americans’ retirement readiness indicates a wide range of preparedness for the golden years. Called a “crisis” by researchers, retirement for some may include significant choices: continued employment or utilization of social welfare services. This article describes factors contributing to the retirement crisis and roles social workers can play in assisting older retirees. Disparity in household retirement savings exists by ethnicity. On the front lines serving aging individuals and their families, social work professionals are well situated to collaborate with individuals, and other providers, to address financial, social and emotional pillars necessary in facilitating a safe and secure retirement.     

User involvement and empowerment among asylum seekers in Norwegian reception centres

A considerable amount of literature has been published on conditions in reception centres for asylum seekers. The previous studies show that the life of residents in the centres is characterised by uncertainty, passivity, powerlessness and gradual disqualification. Drawing from data collected from asylum seekers and service providers in Norwegian reception centres, this article examines the tools used to counteract these processes. The article maintains that organised activities, such as language courses and user involvement in the form of cooperative councils, have an impact on the empowerment of asylum seekers. However, user motivation for participation and involvement in these arrangements is undermined, due to residents' responses on factors which operate both at the structural and relational level. The findings and questions raised in the article have wider implications for social work with asylum seekers in other European countries, as well as for current efforts being made by EU countries to regulate reception conditions for asylum seekers. Among other things, the authors relate their findings to reception standards as defined in the EU Directive on Reception Conditions for asylum seekers.     

Nordic Employment Policies – Change and Continuity Before and During the Financial Crisis

The Nordic countries serve as models for successful employment and labour market policies. In this article, Nordic employment and labour market policies are analyzed from a comparative point of view. It is argued that Nordic employment and labour market policies have lost some of their distinctive features. Active labour market policies, for example, are now at the centre of policy priorities in many countries of the EU. And in some other respects, the Nordic countries have converged towards political patterns characteristic for states in central Europe, for example, de‐centralized patterns of wage bargaining and the partial lack of corporatist concertation. During the current financial crisis, specific patterns of crisis management can be observed in Scandinavia that make these countries distinct from many other countries in Europe.     

Risk, Statistical Inference, and the Law of Evidence: The Use of Epidemiological Data in Toxic Tort Cases

Toxic torts are product liability cases dealing with alleged injuries due to chemical or biological hazards such as radiation, thalidomide, or Agent Orange. Toxic tort cases typically rely more heavily than other product liability cases on indirect or statistical proof of injury. There have been numerous theoretical analyses of statistical proof of injury in toxic tort cases. However, there have been only a handful of actual legal decisions regarding the use of such statistical evidence, and most of those decisions have been inconclusive. Recently, a major case from the Fifth Circuit, involving allegations that Benedectin (a morning sickness drug) caused birth defects, was decided entirely on the basis of statistical inference. This paper examines both the conceptual basis of that decision, and also the relationships among statistical inference, scientific evidence, and the rules of product liability in general.
