The household registration system and social stratification in China: 1955–1996

The Chinese household registration system (hukou), which divides the population into "agricultural" and "nonagricultural" sectors, may be the most important determinant of differential privileges in state socialist China, determining access to good jobs, education for one's children, housing, health care, and even the right to move to a city. Transforming one's hukou status from rural to urban is a central aspect of upward social mobility. Using data from a 1996 national probability sample, we show that education and membership in the Chinese Communist Party are the main determinants of such mobility.     

A diagrammatic exposition of justice

Several different analytical theories of justice are analyzed in the context of a uniform diagrammatic exposition. The diagrams make use of ordinary economic tools of analysis - production possibility frontiers and indifference curves. Additionally, numerous propositions are set forth which establish either the critical differences between alternative theories, or the conditions under which different theories yield identical results.This paper is a revised version of a lecture delivered at the University of Chicago (1976) and at the Public Choice Meetings in New Orleans (1978).     

Uneven Development in North Carolina? Job Quality Differences Between Local and Nonlocal Firms1

Abstract Do outside firms come to North Carolina or, more generally, to the rural South to take advantage of the low-wage unorganized local relations of production? Do they disrupt local labor market arrangements? We use data from a survey of North Carolina employees to examine labor market and job quality differences between local and outside firms and also the organization of regional labor markets. Results, based on multiple regression models, suggest that outside firms provide higher quality jobs, mediated by organizational resources and internal firm relations of production. Urban Piedmont labor markets provide better jobs than rural labor markets, regardless of the establishment's ownership locale. Generally, uneven development predictions are supported by additive models, but challenged by additional analyses of interactions. These analyses suggest that outside firms may be undermining local relations of production in rural North Carolina. Results of this research present rural policymakers with a challenge for future economic development strategies.     

Millions of election outcomes from a single profile

By changing the choice of a positional voting method, different election rankings can result from a fixed profile. A geometric theory is developed to explain why this occurs, to completely characterize all possible sets of rankings that can arise in this manner, to determine the number of rankings and other properties of these sets of rankings, to design profiles that cause the different conclusions, to develop elementary tools to analyze actual data, and to compare new types of social choice solutions that are based on the set of rankings admitted by a profile. A secondary theme is to indicate how results for voting theory can be obtained with (relative) ease when they are analyzed with a geometric approach.This research was supported by NSF Grant IRI-9103180.     

Laws of the iterated logarithm and large deviations for a class of diffusionl processes

We use the martingale approach to study large deviations and laws of the iterated logarithm for certain multidimensional diffusion processes. The criteria for the validity of these properties are expressed in terms of averaging properties of the coefficients of the infinitesimal generator. In particular we apply our results to diffusion processes with random coefficients.     

Public goods and Arrovian social choice

A social welfare function satisfying Arrow's independence axiom is constant or authoritarian if it generates continuous and transitive social preferences over the space of allocations of public and private goods, and individual preferences have the classical economic properties. The social welfare function will be oligarchial if it generates continuous and quasitransitive social preferences and satisfies a weak version of the Pareto criterion in addition to the independence axiom.This work was supported by the National Sciences Foundation grant no.

The Influence of Situational Ethics on Cheating Among College Students*

This research examines the influence of situational ethics on cheating among college students. The analysis of responses from 6,096 students at thirty-one diverse schools suggests that neutralization is a significant factor in justifying the violation of institutional norms on academic honesty. Although cheating is generally seen as wrong, students identify many situations in which they feel cheating is acceptable.
