Has the progress of output convergence changed within the United States? This article examines the output convergence among U.S. states for the last five decades by making several improvements over the extant literature. By applying a battery of convergence tests designed to capture nonlinear transitional dynamics to real output per worker data (i.e., nominal values deflated by state‐level price), we find that output convergence has not been a feature of the continental United States since the 1970s. Instead, output convergence has proceeded among four subgroups within which constituent states have certain characteristics in common. Our regression analysis suggests that state‐level characteristics related to technology and human capital play a crucial role in accounting for the formation and composition of convergence clubs, in agreement with the recent theoretical models of growth and development (e.g., Aghion et al. 2009; Gennaioli et al. 2013b). The level of technology, proxied by patents, turns out to be a consistently significant determinant even after controlling for endogeneity, suggesting that frictions in the diffusion of technology and human capital may have led to clustering of states with different levels of productivity. Our results therefore cast doubt on the common view that diffusion of knowledge and technology across state borders is frictionless. (JEL O47, O51)  相似文献

Policies to reduce carbon emissions by vehicles, such as fuel economy standards and gasoline taxes, have impacts on vehicle weight and thus on safety. This paper develops a model that separately identifies the impact of vehicle weight on mortality and selection effects that impact accident propensity. The main results are that (1) the safety externalities associated with heavy vehicles are greater than the environmental ones; (2) under fuel economy standards, vehicle weights have recently decreased with little likely effect on accident deaths; and (3) similar environmental benefits could be combined with substantial reductions in deaths by implementing higher gasoline taxes.

Speaking to the debate on the nature of critique, this article is about the struggle to produce an account when listening to and retelling stories. It begins with the disconcertment over listening to a coherent story that emerges in interviews about the development of performance indicators for Dutch hospital care. The indicators are presented as solutions to the problem of unruliness in the healthcare world. Drawing on Helen Verran's work on generative critique I slow down the ‘problem‐solution‐found’ plot. Instead of contrasting the apparently coherent stories with the complexities of an ‘underlying’ practice of healthcare, I hold on to my initial disconcertment so that ‘fleetingly subtle’ interruptions become entry points for generative critique. Taking Eduardo Viveiros de Castro's understanding of the relation that fear and laughter have to alterity, I show how fear and laughter permit generative critique within seemingly coherent stories. In the case of indicator development, the interviewees ‘laugh away’ what they consider alter from quality and safety in healthcare: having no control over what is going on, polyglotism instead of a common language, and inaction as opposed to taking one's time. Paying attention to disconcerting interruptions generates sensitivity and questions rather than yet another set of (critical) problem‐solution‐found answers. How can ridiculed (laughed away) subjectivity be acknowledged as important entry points for including alterity in supervision? And how to position the acknowledgement, not as an antidote, but as a way of rendering the fear of alterity generative? Nurturing sensitivities is crucial for keeping open, which means resisting both the sticky tendency of normalizing accounts and the fallacy of misplaced concreteness. I conclude that keeping open by re‐imagining critique resonates with the creativity of collective life in actual times and places. Thereby it offers a promising potential for doing worlds differently.  相似文献

Despite the importance of grandparents in their grandchildren's lives, little is known about grandparent–grandchild contact after parental divorce. In this study, the authors investigated differences in grandparent–grandchild contact across 3 postdivorce residence arrangements (mother residence, father residence, and shared residence) using recent survey data from the Netherlands (N = 3,842). The results indicated that contact with maternal grandparents after divorce was highest in mother‐residence arrangements, followed by shared residence and then father residence. Contact with paternal grandparents was highest for children in father‐residence and shared‐residence arrangements, followed by mother residence. Parental conflict had little influence on children's contact with maternal grandparents, but it decreased contact with paternal grandparents. Moreover, the results partly support the assumption that conflict moderates the relationship between residence arrangements and grandparental contact, with differences between residence arrangements being more pronounced in the case of high‐conflict divorced families than in low‐conflict ones.  相似文献

Finnish parents' views on responsibility in the home–school relations were explored. Responsibility was here understood as responsibility over education and upbringing. The data consist of semi‐structured interviews with 24 mothers and four fathers. In the home–school discourses, parents and teachers were often referred to as partners, and active parental involvement in school life was seen as a key to children's success. However, in some discourses teachers and parents were seen as polar opposites, e.g. teachers as experts — parents as laymen. Few references were made to children's responsibility.  相似文献

In recent years, the term social entrepreneur has become increasingly common in academic and business circles. Social entrepreneurs engage in a variety of activities, but always with the intention of solving social problems. Social entrepreneurs are not merely people who perform acts of charity; they have an evident desire to improve social well‐being and develop projects with long‐term vision. The creation of sustainable social value is a key characteristic that differentiates them from well‐meaning individuals who simply engage in charitable works. There are, however, significant gaps in our understanding of social entrepreneurs and few empirical studies on the subject. This present study attempts to identify the characteristics of more socially oriented entrepreneurs, using sociodemographic variables and the theory of universal values toward work. Analysis of a sample of approximately 400 people shows that more than half of entrepreneurial orientation can be explained through the possession of the values of self‐enhancement (with an inverse relationship in this case), self‐transcendence, and conservation. The theory of universal values has proved extraordinarily useful for studying the characteristics of social entrepreneurs.  相似文献

Chilean governments since 1990 have relied on economic growth to generate employment, higher wages and better conditions of employment. But the results of this policy have been mixed: quantitative improvements in employment and wages have not been matched by improvements in job quality. Contrasting Chile's seemingly rigid regulatory framework with its actual labour market flexibility, the authors stress the importance of employment conditions in assessing labour market performance. They empirically explore the effects of individual and job characteristics on employment and income‐generating capabilities, whose most powerful determinant, they find, is employment under an open‐ended contract. They conclude with a discussion of policy implications.  相似文献

The current study examined the associations between multiple aspects of the friend relationship (connection, companionship, psychological control) and global prosocial behavior toward friends. Participants included 467 early adolescents (M age of child = 13.32, SD = 1.05, 49% female, 69% European American), and data were collected at two time points, roughly 1 year apart. Structural equation modeling suggested that friend psychological control was negatively associated with prosocial behavior toward friends, while friend connection was positively associated (via adolescent sympathy). Discussion focuses on the friend relationship as an important influence on adolescent sympathy and prosocial behavior toward friends.  相似文献

Rapidly changing demographics of American families have redefined coparenting and brought about the need for cross‐disciplinary measurement and theory integration that is grounded in a developmental, life course perspective. First, we briefly review sociological scholarship on coparenting, highlighting both qualitative and quantitative work. Second, we provide a brief historical overview of coparenting from the psychological perspective, focusing on its theoretical foundation, multiple components, and importance for individuals and families. Third, we highlight the strengths and weaknesses of sociological approaches to coparenting and discuss the benefits of integration. Finally, we suggest avenues for future interdisciplinary work on coparenting that are heavily shaped by the shifting demographics of American families.  相似文献

The ability of infants to recognize phonotactic patterns in their native language is widely acknowledged. However, the specific ability of infants to recognize patterns created by nonadjacent vowels in words has seldom been investigated. In Semitic languages such as Hebrew, groups of multisyllabic words are identical in their nonadjacent vowel sequences and stress position but differ in the consonants interposed between the vowels. The goals of this study were to assess whether infants learning Hebrew show a preference for (1) a nonadjacent vocalic pattern or template, common in Hebrew nouns (CéCeC), over a nonattested nonadjacent vocalic pattern (CóCoC), and (2) a nonadjacent vocalic pattern common in Hebrew words (CaCóC) over an existing but less common pattern (CaCéC). Twenty Hebrew‐learning infants aged 8 to 11 months were presented with lists of nonsense words featuring the first two patterns (Experiment 1), and 20 were presented with nonsense words featuring the second two patterns (Experiment 2). The results showed longer listening to CéCeC than to CóCoC lists and to CaCóC than to CaCéC lists, suggesting that infants recognized the common nonadjacent vocalic patterns in both cases. The study thus demonstrates that Hebrew‐learning infants are able to disregard the intervening consonants within words and generalize their vocalic pattern to previously unheard nonwords, whether this pattern includes identical or different vowels and regardless of the rhythmic pattern of the word (trochaic or iambic). Analysis of the occurrence of the relevant vowel patterns in input speech in three Hebrew corpora (two addressed to children and one to adults) suggests that exposure to these patterns in words underlies the infants' preferences.  相似文献
