Altruism and culture as social products

The historical core of the independent sector is comprised of churches, charitable organisations and higher education. What distinguishes these and other independent sector organisations from the governmental and commercial sectors is the fact that participation in the independent sector is free from state compulsion and not for the purpose of monetary gain. The independent sector is a modern development which could not have occurred without the disestablishment of religion. Disestablished churches have given rise to secular charities, higher education and other independent sector organisations in the United States. The independent sector is the arena in which cultural production and altruistic activities with a distinctive moral quality take place. Participation in the independent sector is the only mechanism for status legitimation in a democractic society with no compulsory state religion or traditional forms of authority.     

The organizational politics of the ASA

The American Sociological Association’s Report on Future Organizational Trends arose from worries that the ASA is disintegrating into a conglomerate of mutually oblivious specialities. The proliferation of sections was regarded as an aspect of this disintegration that the ASA might be able to control. But the committee charged with examining the problem of sections concluded that section expansion has become a major form of political mobilization within the association, and that sections act as a counterweight to the bureaucratic centralization of the ASA as a whole. On balance, the committee opted for the local vitalization going on in sections as against the more abstract concerns of the ASA central governing bodies. His books includeWeberian Sociological Theory (1986),Theoretical Sociology (1988), andSociology of Marriage and Family: Gender, Love and Property (third edition co-authored with Scott Coltrane, 1990).     

An Examination of the Asymmetric Effects of Money Supply Shocks in the Pre–World War I and Interwar Periods

We test whether monetary shocks had asymmetric output effects before World War II. Ball and Mankiw (1994) show that expectations of persistent inflation under fiat money can explain why negative monetary shocks had larger effects than positive shocks after World War II. Consistent with this explanation, we find such asymmetry in the interwar period following the abandonment of the gold standard and before it, when agents arguably anticipated this development. We find no monetary asymmetry before World War I, which is consistent with Ball and Mankiw (1994), because under a credible gold standard, agents do not expect persistent inflation.     

Identification of Ethnic Settlement Regions: Amish-Mennonites in Ohio

Abstract The persistence of ethnic settlement in rural regions of the United States is well documented. Yet, there has been little discussion of techniques which allow the identification of the geographic extent and concentration of distinctive ethnic populations. Amish-Mennonite settlement constitutes a unique component of the rural landscape. A wide range of visual clues alert the observer to their presence, but without painstaking field surveys it is difficult to establish their geographic extent. This paper examines four approaches to the identification of Amish-Mennonite settlement. These are county-based population data on religious affiliation, the location of Amish church districts and Mennonite churches, topographic maps, and surnames and cadastral maps. Topographic maps proved unsuitable, but each of the other approaches produced reasonable approximations of the areal extent of Amish-Mennonite settlement. Surnames and cadastral maps present good possibilities for the identification of other ethnic populations in rural regions.
