Seeking Closure: Competition in Complementary Markets*

When offering a product that has a complementary product in a different market, a firm must consider the interdependence between the complementary products as well as the competition within markets. If the firm participates in both markets, the balancing act becomes even more challenging. This article provides insights about strategies in this latter setting: when should the firm seek to keep its products closed to competing complementary products, and when would the firm be better off by accepting a common standard? To address these questions, we employ standard game theoretic analysis to a simple spatial model that captures aspects of both intermarket externalities and intramarket competition. We find that if a firm participates in both markets and chooses a closed standard, it achieves lower profits compared to an open standard, but gains greater market share. Surprisingly, we find that customers are better off when standards are kept closed.

Inter- and transdisciplinary approaches to population–environment research for sustainability aims: a review and appraisal

The causes and consequences of demographic changes for the environment, and the possible ways of influencing population dynamics to achieve ‘sustainability’, have been the subject of many debates in science and policy in recent decades. However, the body of knowledge concerning relationships between population dynamics and sustainability is quite fragmented, dispersed over many disciplines, and encompasses diverse theories, paradigms and methodologies. This paper reviews four selected frameworks: linear, multiplicative, mediated, and system-theoretical approaches and perspectives. We represent how population–environment relationships are conceptualized, provide examples of research questions and accepted approaches, and critically assess their utility for different sorts of research for sustainable development. We note the growing recognition of the value of embracing complexity in population–environment research, and how this is consistent with normative aims of development.     

Lessons Learned From the Supporting Father Involvement Study: A Cross-Cultural Preventive Intervention for Low-Income Families With Young Children

ABSTRACT

Despite the proliferation of fatherhood programs designed to promote paternal involvement and positive family outcomes, evaluations of these programs are scarce. The Supporting Father Involvement (SFI) study is a randomized clinical trial comprised of 289 low-income Spanish- and English-speaking families living in California. The evaluation design reflects a partnership stance that promotes empowerment of staff and social service agencies. This article examines lessons learned from the program's first 3 years (2002–2004) from the perspectives of both evaluators and program staff. The lessons cover a broad range of areas, including communication procedures, training, staffing, recruitment/retention, clinical needs, intervention content and process, and maintaining cultural sensitivity.     

Gender Minority Stress: A Critical Review

ABSTRACT

Past studies that compare cisgender to transgender (or trans) and gender diverse people have found a higher prevalence of mental health problems among the latter groups. This article uses Testa’s gender minority stress framework, which is an expansion of minority stress theory, to assess minority stressors that are specific to the experiences of trans and gender diverse people. The concept of cisnormativity, an ideology that positions cisgender identities as a norm, is used in relation to the gender minority stress framework to describe the marginalizing nature of social environments for trans and gender diverse people. This article provides a critical review that integrates and expands on past theoretical perspectives on gender minority stressors and protective factors. Specifically, this article demonstrates the relevance of cultural and ethnic backgrounds to complement the application of intersectionality in research on health disparities experienced by trans and gender diverse people.     

Race,gender, and marriage: destination selection during the great migration

Using historical census microdata, we present a unique analysis of racial and gender disparities in destination selection and an exploration of hypotheses regarding tied migration in the historical context of the Great Migration. Black migrants were more likely to move to metropolitan areas and central cities throughout the period, while white migrants were more likely to locate in nonmetropolitan and farm destinations. Gender differences were largely dependent on marital status. Consistent with the "tied-migration" thesis, married women had destination outcomes that were similar to those of men, whereas single women had a greater propensity to reside in metropolitan locations where economic opportunities for women were more plentiful.     

Coordination in Games with Strategic Complementarities: An Experiment on Fixed vs. Random Matching

In this article, we study behavior in a series of two‐player supply chain game experiments. Each player simultaneously chooses a capacity before demand is realized, and sales are given by the minimum of realized demand and chosen capacities. We focus on the differences in behavior under fixed pairs and random rematching. Intuition suggests that long‐run relations should lead to more profitable outcomes. However, our results go against this intuition. While subjects' capacity choices are better aligned (i.e., closer together) under fixed pairs, average profits are more variable. Moreover, learning is slower under fixed pairs—so much so that over the last five periods, average profits are actually higher under random rematching. The underlying cause for this finding appears to be a “first‐impressions” bias, present only under fixed matching, in which the greater the misalignment in initial choices, the lower are average profits.     

Mother needs a bigger “helper”: A critique of “wine mom” discourse as conformity to hegemonic intensive motherhood

“Wine mom” discourse encourages American women to self-deprecatingly bond over the stressors of parenting and touts alcohol use as necessary means for coping and escapism. Before the added stress of the COVID-19 pandemic, whereby alcohol sales and consumption increased in the United States, rates of heavy drinking and alcohol-related illnesses among US women have been steadily increasing. Exceeding the clinical markers of responsible alcohol use, “wine mom” discourse normalizes an inextricable link between alcohol misuse and expectations of (White, middle-class) motherhood. Online communities and businesses emphasize “wine mom” discourse for self-acceptance and bonding in response to the impossible demands of hegemonic motherhood. In this critique of “wine mom” discourse, we argue that although alcohol consumption is commonly touted as self-care, this messaging operates in toxic ways that harms women and reinforces patriarchy. Applying Merton's strain theory, we argue that “wine mom” trends and related discourse encompass a harmful form of conformity, if not false resistance, to the strain of flawed cultural goals and lacking institutionalized supports for American mothers. We call for true rebellion, emphasizing positive discourse as well as structural changes and policy reforms to dismantle patriarchal barriers and hegemonic motherhood constraints to better support American families.     

The Changing Demography of America's Families

We use data from a variety of sources to describe recent dramatic changes in the composition, economic stability, and diversity of American families. The declining prevalence of early marriage, increasing level of marital dissolution, and growing tendency to never marry, especially among some racial and ethnic groups, reflect changes in the relative economic prospects of men and women and support the conclusion that marriage is becoming less valued as a source of economic stability. These developments also imply that relatively more children are born outside of marriage, spend at least part of their childhood in a single‐parent household, and endure multiple changes in family composition. Paralleling these trends have been sharp changes in the economic stability of families, characterized most notably by a growing importance of women's income and increasing economic inequality among American families.
