Abstract
We propose that the geographic distribution of entrepreneurship evolves as developing communication systems alter the spatial scope of competition Our arguments imply that as spatial barriers to communication diminish founding events will be less sensitive to local context and more sensitive to distant competition. We test this argument with data on the first modern communication system, the US post office, and foundings of organizations that depended on it for distribution: magazine-publishing ventures. We find that as the postal system expanded, the spatial scope of competition among magazines increased: magazines in distant locations exerted more negative effects on local founding rates, whereas magazines in the focal location exerted less positive effects on local founding rates These findings reveal how spatial barriers to competition shape the geography of entrepreneurial activity.

Abstract
Some risks of having children at older ages are widely documented, and the “biological clock” is a popular media concern, but the association between cognitive disability generally and both mothers’ and fathers’ age is not well known. This article assesses descriptively the relationship between children’s cognitive disability and parents’ age at birth, using a sample of 353,119 children aged five to eleven living with two married parents from the 2009-2011 American Community Survey. Cognitive disability varied by parental age categories from 1.8 percent to 5.4 percent, with overall rates of 2.2 percent. Odds of disability were much more strongly associated with mothers’ age at birth than with fathers’ age at birth, with the highest odds for children whose mothers were age 45 or higher at the time of their birth (adjusted odds ratio 2.7 relative to age 30 to 34) and the lowest for those born to mothers in their early 30s. These results demonstrate that the risk is strongly associated with the mother’s age at birth—but not the father’s. This is consistent with previous research showing that it is the mother’s health, rather than age per se, that is most important for the health of their children.

Abstract
This article develops a sociologically informed approach to market bubbles by integrating insights from financial-economic theory with the concepts of voice and dissimulation from other cases of distorted valuation studied by sociologists (e.g., witch hunts, unpopular norms, and support for authoritarian regimes). It draws on unique data—longitudinal interviews with private equity market participants during and after that market’s mid-2000s bubble—to test key implications of two existing theories of bubbles and to move beyond both. In doing so, the article suggests a crucial revision to the behavioral finance agenda, wherein bubbles may pertain less to the cognitive errors individuals make when estimating asset values and more to the sociological and institutionally driven challenge of how to interpret complex social and competitive environments.

Abstract
We use data from a national survey of likely voters conducted before the 2008 election to study the association between Obama’s perceived racial identity and voters’ choices. Voters who saw Obama as biracial were substantially more likely to vote for him, suggesting that many Americans regard a biracial identity more favorably than a black identity. The relationship was stronger among Democrats than among Republicans. The potential implications of our findings for the future of race in American politics are discussed.

Abstract
This article models the implications of innovations being nested within categories. In effect, social actors assess the legitimacy of innovations vis-à-vis conformity to categories such that a sufficiently legitimate innovation may be adopted without direct reference to the behavior of peers. However, when innovations lack categorical legitimacy, actors default to proximately peer-oriented heuristics such as information cascades. Eventually, if enough similarly novel innovations achieve widespread popularity, their conventions will become accepted as a legitimate category. Thus density creates legitimacy, but this density can be at the level of the particular innovation or of the category within which it is embedded.

Abstract
Despite the striking reversal of the gender gap in educational attainment and the near–gender parity in math performance, women pursue science and engineering (S/E) degrees at much lower rates than their male peers do. Current efforts to increase the number of women in these fields focus on different life-course periods but lack a clear understanding of the importance of these periods and how orientations toward S/E fields develop over time. In this article, we examine the gendered pathways to a S/E bachelor’s degree from middle school to high school and college based on a representative sample from the 1973 to 1974 birth cohort. Using a counterfactual decomposition analysis, we determine the relative importance of these different life-course periods and thereby inform the direction of future research and policy. Our findings confirm previous research that highlights the importance of early encouragement for gender differences in S/E degrees, but our findings also attest to the high school years as a decisive period for the gender gap, while challenging the focus on college in research and policy. Indeed, if female high school seniors had the same orientation toward and preparation for S/E fields as their male peers, the gender gap in S/E degrees would be closed by as much as 82 percent.

Abstract
What explains the relative persistence of same-race romantic relationships? One possible explanation is structural–this phenomenon could reflect the fact that social interactions are already stratified along racial lines–while another attributes these patterns to individual-level preferences. We present novel evidence from an online dating community involving more than 250,000 people in the United States about the frequency with which individuals both express a preference for same-race romantic partners and act to choose same-race partners. Prior work suggests that political ideology is an important correlate of conservative attitudes about race in the United States, and we find that conservatives, including both men and women and blacks and whites, are much more likely than liberals to state a preference for same-race partners. Further, conservatives are not simply more selective in general; they are specifically selective with regard to race. Do these stated preferences predict real behaviors? In general, we find that stated preferences are a strong predictor of a behavioral preference for same-race partners, and that this pattern persists across ideological groups. At the same time, both men and women of all political persuasions act as if they prefer same-race relationships even when they claim not to. As a result, the gap between conservatives and liberals in revealed same-race preferences, while still substantial, is not as pronounced as their stated attitudes would suggest. We conclude by discussing some implications of our findings for the broader issues of racial homogamy and segregation.

Abstract
We argue that time is a network good: its value depends on the number of social others who have the same schedule of time available. We demonstrate this in a comparative analysis of how the standard workweek shapes the social time and emotional well-being of workers and the unemployed. Drawing on two independent data sets, with more than half a million respondents, we show that both workers and the unemployed experience remarkably similar increases in emotional well-being on weekends and have similar declines in well-being when the workweek begins. The unemployed look forward to weekends much the same as workers. This is in large part because social time increases sharply on weekends for both workers and the unemployed. Weekend well-being is not due to time off work per se but rather is a collectively produced social good stemming from widely shared free time on weekends. The unemployed gain comparatively little benefit from their time off during the week, when others go to work.

Despite the tremendous amount of attention that has been paid to the internet as a tool for civic engagement, we still have little idea how “active” is the average online activist or how social networks matter in facilitating electronic protest. In this paper, we use complete records on the donation and recruitment activity of 1.2 million members of the Save Darfur “Cause” on Facebook to provide a detailed first look at a massive online social movement. While both donation and recruitment behavior are socially patterned, the vast majority of Cause members recruited no one else into the Cause and contributed no money to it-suggesting that in the case of the Save Darfur campaign, Facebook conjured an illusion of activism rather than facilitating the real thing.
