An integrated system for demographic estimation from two age distributions

This paper presents a simple method for estimating a birth rate and a level of mortality for an intercensal period. The birth rate is estimated from the intercept of a line fitted to data and the level of mortality from the slope of that line. The formula that is developed is based upon a recent generalization of stable population relations. An estimate of childhood mortality level is an optional but significant piece of additional input. An important by-product of the procedure is an estimate of the true age distribution.     

GROUP INEQUALITY

We explore the combined effect of segregation in social networks, peer effects, and the relative size of a historically disadvantaged group on the incentives to invest in market‐rewarded skills and the dynamics of inequality between social groups. We identify conditions under which group inequality will persist in the absence of differences in ability, credit constraints, or labor market discrimination. Under these conditions, group inequality may be amplified even if initial group differences are negligible. Increases in social integration may destabilize an unequal state and make group equality possible, but the distributional and human capital effects of this depend on the demographic composition of the population. When the size of the initially disadvantaged group is sufficiently small, integration can lower the long‐run costs of human capital investment in both groups and result in an increase the aggregate skill share. In contrast, when the initially disadvantaged group is large, integration can induce a fall in the aggregate skill share as the costs of human capital investment rise in both groups. We consider applications to concrete cases and policy implications.     

Privatization and National Development: A Case Study of Ghana

Proponents of privatization claim that privatization can enhance efficiency, reduce public sector debt and consequently improve overall economic performance. However, in many developing countries, and Africa in particular, the evidence is mixed. An exploratory study is done from the perspective of citizens’ about the impact of privatization on the Ghanaian national economy. The findings of the study suggest that: 1) the privatization program is pro rich; it benefits the economic and political elites more than it benefits the nation as a whole; 2) there is a high level of corruption associated with the privatization process; and 3) Privatization is not considered as one of the most important tools needed for national development, though the survey finds that many respondents believe that there is the need for some reforms in the public sector to promote national development. The results of the study indicate that administrative and political problems cannot be overcome simply by reducing the size of the state bureaucracy, but rather making government more accountable in meeting the needs of its people.     

Changing Attitudes Toward the Homeless: The Effects of Prosocial Communication With the Homeless

One hundred, thirty-four undergraduate students participated in a field experiment designed to examine the effects of extended, prosocial communication with homeless persons, upon attitudes toward the homeless problem, of behavioral intentions towards the homeless, and of causal attributions about homelessness. It was expected that prosocial interaction with the homeless would produce shifts in attitudes and behavioral intentions toward the homeless and homelessness and result in greater attributions of external causes to explain homelessness. Nineteen experimental participants worked 15 hours at a local homeless shelter. Their responses to a posttest questionnaire that measured a range of attitudinal and behavioral orientations toward the homeless were compared with control participants who did not work at the shelter. Subsequent analyses furnished strong evidence of positive changes in attitudes and intentions toward homelessness among the shelter workers. These participants evaluated homeless people as less blameworthy and more socially attractive than did control participants; moreover, shelter workers indicated more personal responsibility and behavioral commitment to helping the homeless than control participants. They also perceived the homeless problem to be more serious and were more likely to attribute homelessness to bad luck than control participants. However, the two groups were equally likely to attribute homelessness to various external causes such as the economy, housing costs, and governmental policies. The results are interpreted as having policy implications for volunteer service.
