PATENT BREADTH IN AN INTERNATIONAL SETTING

We examine the Nash equilibria of a game where two national governments set patent breadth strategically. Broader patents make R&D more attractive, but the effect on static efficiency is nonmonotonic. In a North–South model, where only the North can innovate, harmonization of patent breadth lowers welfare relative to the Nash equilibrium. When both countries can innovate, harmonization toward narrower patent breadth may raise world welfare. (JEL F02, F13, O3, O31, O32)     

THE STRUCTURE OF FAMILY PARADIGMS: AN ANALYTICAL MODEL OF FAMILY VARIATION

The theory of family paradigms provides an integrative framework for under-standing and systematizing the diverse ways that families organize and make sense of family life. Using formal methods of analysis based on logical and geometrical arguments, the priecise implications of models of family types can be investigated and compared. The paradigmatic framework can thus be refined and extended to form a more rigorous theoretical grounding for family typologies is explored and a miltidimensional model is derived the geometry of which is equivalent to, but more succinctly captures, the underlying structure of uariation in family para-digms. In Part II, the resulting model is interpredtd and explored in terms of implications for family theory, theory construction, and family therapy. Clarifying the basic dimensions of the paradigmatic framework also permits more precise exploration of interrelationships among related models of family types, which can be understood as reduced models derivable from the complete geometry of the paradigmatic framework.     

AN EVOLUTIONARY EXPLANATION FOR ROTTEN KIDS

We explore how natural selection acts upon genes for cooperation, altruism and selfishness in an prisoner's dilemma played by family members. A key parameter determining behavior is that parents and children have different expectations of future offspring. Examining asexual and sexually reproducing populations we show that which strategy of cooperation and defection proves be stable depends on the relative reproduction potential of the players and what proportion of the population is young. "Rotten kids" with altruistic parents can be a stable outcome where reproductive success is the goal, and natural selection may lead individuals to care about their unborn progeny.

DEVELOPING AN IDENTITY AS A FEMINIST FAMILY THERAPIST: IMPLICATIONS FOR TRAINING

Although feminists have profoundly influenced the field of family therapy, little has been written about the process by which these women came to identify themselves as feminist family therapists. This article reports the results of a qualitative research study that explored that process and suggests a model of feminist family therapy identity development. Implications for training programs are reveived.     

TOO-BLUE: COLOUR-PATCH FOR AN EXPANDED EMPIRICISM

This essay is in part a response to the rhetoric of the ‘two cultures’ revived by the ‘science wars’ conducted in recent years through the mass media against humanities disciplines, especially ‘post-modern’ art, cultural studies, and non-analytic philosophy. The essay focuses in greatest detail on the relation between science and philosophy, arguing that they are in fact complementary activities effectively partaking of the same reality. Although knowledge practices in the humanities draw from their partaking radically different orders of result from those of science (and from each other), they have claim to an effective connection to a shared reality. Humanities disciplines, and even ‘informal’ or ‘traditional’ knowledge practices, can be argued to be realist, empirical enterprises generating modes of validity specific to their manner of result – provided that the definition of empirical reality is generously broadened. An ‘expanded’ empiricism is a ‘radical’ empiricism in William James's sense of taking relations to be as real and as fundamentally given to experience as discrete objects or sense-data. Recognizing the reality of relation nudges empiricism in the direction of process philosophy. The essay reviews concepts of cause and discovery, nature and culture, affect and virtuality, truth and constructedness, taking the experience of colour as a prime example. It combines elements of James's radical empiricism with Whitehead's process philosophy with the poststructuralism of Deleuze and Guattari with chaos and complexity theory. The resulting perspective converges with Isabelle Stengers' vision of a non-judgemental political ecology of knowledge. An expansive ethics of relationality, of mutual differential belonging, is the natural correlate of an expanded culture of empiricism.     

AN EVOLUTIONARY MODEL OF TASTE FOR RISK

Economists take tastes as given. However, tastes must be derived from biological models of evolutionary survival; we exhibit those tastes which served to make our ancestors survive. In particular, economists have no theory which explains observed behavior towards risk; rather, we take behavior as a datum. In this paper we present a model which explains risk seeking by adolescents and risk aversion by mature males as the result of an evolutionary mechanism.     

MOTIVATIONAL INTERVIEWING AS AN INTERVENTION FOR AT-RISK COUPLES

Thirty-one couples participated in a pilot, motivational interviewing, intervention for at-risk couples called the Marriage Checkup (MC). The MC consisted of thorough relationship assessment and individualized feedback. It attracted substantial numbers of at-risk couples who were not otherwise seeking treatment. Partners' marital satisfaction improved significantly from pre- to post-check-up and remained improved at 1-month follow up. Partners were no longer significantly different from a non-distressed comparison group following intervention. Although not addressing the efficacy of the MC, this study supports its viability as an indicated preventive intervention with couples at-risk for severe marital distress by addressing its attractiveness, tolerability, and safety.     

A MODEL OF "FAMILY FAIRNESS" AND ITS IMPLICATIONS FOR DEBT NEUTRALITY

Evidence suggests that a signcant proportion, though by no means all, of bequests is equally divided among the beneficiaries. This is inconsistent with standard models of bequests, which predict that equal division should occur only by chance. This paper proposes a modified model incorporating "family fairness" as well as utilitarianism as an influence on behavior. Various implications for debt neutrality are analyzed.     

AN ECONOMIC ANALYSIS OF THE DEMAND FOR ABORTIONS

This study uses an economic model of fertility control to estimate the demand for abortions. The results show that the fundamental law of demand holds for abortions, with the price elasticity of demand equal to –.81. Abortions are a normal good with an income elasticity of demand equal to .79. The demand for abortions is also positively related to the labor force participation of women and to being unmarried. Catholic religion, education and the poverty status of women were found to have no statistically significant impact on the demand for abortions.     

A MODEL OF OPTIMAL PLANT SIZE WITH AN APPLICATION TO THE DEMAND FOR COGNITIVE ACHIEVEMENT AND FOR SCHOOL SIZE

A model of optimal plant size is developed which predicts that 1) plants experience increasing returns to in-plants inputs, 2) the relative price of plant output is greater in rural areas than in urban areas, and 3) plants are larger in urban areas than in rural areas. The model's predictions appear to be consistent with behavior in a number of consumer services (e. g., grocery, movie, and library services). These predictions are more rigorously tested and are strongly supported when demand functions for cognitive achievement and for school size are estimated. These regressions also lend support to the quality-quantity model of fertility.     

AN EFFICIENCY EXPLANATION FOR WHY FIRMS SECOND SOURCE

Firms facing research costs and demand uncertainty may engage in second-sourcing, in which potential suppliers agree to pool production facilities. I show how sellers and buyers both can benefit from the practice. Second-sourcing allows firms to meet a wider range of possible rates of demand and often to supply a given rate of demand at a lower total cost than under non-cooperation. Buyers benefit through a reduced probability of stock-outs and frequently a lower purchase price. Semiconductor industry data are found to be consistent with the paper's predictions.
