Making Sense of Voluntary Participation: A Theoretical Synthesis*

Abstract This paper examines the influence of community attachment on voluntary citizen participation in rural community improvement projects. We do so by modifying the original systemic model of community attachment (Kasarda and Janowitz 1974) and combining it with tenets of rational choice and social embeddedness theories. The modified model is then extended to consider voluntary participation in community projects by accounting for the influence of community attachment through both a solidarity of interests and a solidarity of sentiments (Bell 1998). Based on survey results of almost 9,000 citizens across 99 small (500–10,000) Iowa communities, findings provide overall support for the expected positive influence of local social ties (weak informal, strong informal, and formal) on the two forms of community attachment which, in turn, positively affect voluntary participation. Attachment in the form of community interests shows a strong direct and indirect effect on voluntary participation, while sentiment's influence is largely indirect. We conclude by considering the relevance of our findings to ongoing discussions of social capital.     

Institutional Access,Residential Segregation,and Urban Black Homicide*

Sociologists have frequently cited the importance of the local institutional base for bolstering social organization and control, and ultimately reducing crime rates. Local noneconomic institutions may be particularly relevant to controlling urban Black crime rates, because in the face of limited access to the legitimate labor force, access to institutions such as churches and civic organizations helps to extend social networks, increase civic engagement, transmit mainstream norms, and provide a forum from which to address community problems. This analysis examines the links between measures of access to such noneconomic institutions and Black homicide rates for a sample of large urban areas circa 1990. The results indicate that after controlling for socioeconomic disadvantage, racial inequality and various other relevant measures, institutional access is negatively associated with Black homicide rates. However, this violence constraining impact appears to be most dramatic in urban areas where Blacks are most highly segregated from Whites. Implications of these results are discussed.     

Maximum likelihood estimation in generalized broken‐line regression

The author examines the existence, uniqueness, and identifiability of estimators produced by maximum likelihood for a model where the canonical parameter of an exponential family gradually begins to drift from its initial value at an unknown change point. He illustrates these properties with theoretical examples and applies his results to global warming data and failure data for emergency diesel generators.     

Religion, Race/Ethnicity, and Beliefs about Poverty

Objective . Although an expanding literature on "stratification beliefs" has developed over the past three decades, research has neglected relationships between religion and beliefs about poverty and other inequalities. This study examines the relationship between religious affiliation and "individualistic,""structuralist," and "fatalistic" beliefs about the causes of poverty, and compares the beliefs of African Americans, Latinos, and whites. Methods . Survey data collected in 1993 from a sample of southern Californians are used to test whether several religious affiliations (Protestant, Catholic, Jew, "other religion," and nonaffiliation) shape beliefs about poverty after controlling for race/ethnicity, SES, gender, and age. In addition, the question of whether African Americans, Latinos, and whites differ in the effects of key religious affiliations is examined. Results . Significant religious affiliation effects are found, net of sociodemographic controls. Protestants and Catholics are strongest on individualistic beliefs; Jews and followers of "other" religions are strongest on structuralist beliefs; Catholics and Jews are strongest on fatalistic beliefs. Finally, race/ethnic differences are found for the effects of key religious affiliations. Conclusion . The analyses demonstrate "religious factors" shaping beliefs about poverty, and reinforce the growing body of evidence that affiliations such as Protestant and Catholic have distinctive meanings and effects along race/ethnic lines in the United States.     

LET'S TALK: HOW COMMUNICATION AFFECTS CONTRACT DESIGN

We study experimentally how communication changes the effectiveness of contract types when sellers choose unenforceable quality after a possible cost shock. Communication potentially removes conflicting perceptions that may otherwise plague flexible contracts. Indeed, we find that introducing free‐form communication sharply reverses an advantage of rigid contracts in favor of flexible contracts, which then deliver much higher earnings. Control treatments that avoid selection effects reveal a strong parallel shift from rigid to flexible. Chat content analysis identifies clarification of post‐shock transfers, promises, and personal rapport as key correlates of high earnings, with clarification working only in conjunction with flexible contracts. A communication channel restricted to clarifying transfer plans also favors use of flexible contracts, but mildly compared to chat. (JEL: C91, D03, D86)     

A MODEL OF NONBELIEF IN THE LAW OF LARGE NUMBERS

People believe that, even in very large samples, proportions of binary signals might depart significantly from the population mean. We model this “nonbelief in the Law of Large Numbers” by assuming that a person believes that proportions in any given sample might be determined by a rate different than the true rate. In prediction, a nonbeliever expects the distribution of signals will have fat tails. In inference, a nonbeliever remains uncertain and influenced by priors even after observing an arbitrarily large sample. We explore implications for beliefs and behavior in a variety of economic settings.
