SPATIAL MOBILITY AND COMMUTING: THE CASE OF TWO‐EARNER HOUSEHOLDS*

ABSTRACT We examine the effects of the spatial configuration of workers' residence and workplace location on intraregional residential and job moving decisions of workers belonging to two‐earner households. We hypothesize that two‐earner households' residential mobility depends positively on the commuting distance of both spouses, but negatively on the distance between workplaces. Further, we hypothesize that workers' job mobility depends positively on the worker's commuting distance, negatively on the spouse's commuting distance, and positively on the distance between workplaces. Using data for Denmark, it appears that these hypotheses hold, and that the effects of the spatial configuration are rather large.     

VARIABLE RETURNS TO SCALE AND REGIONAL RESOURCE ALLOCATION UNDER UNCERTAINTY*

ABSTRACT. This paper investigates the resource allocational implications of intra-industrial externalities, i.e., variable returns to scale (VRS), in a two-region general equilibrium model of production under uncertainty. It is shown that most standard results concerning changes in the goods price ratio with constant returns to scale (CRS) under uncertainty generalize to VRS. In contrast, standard results concerning changes in factor endowments extend from CRS to decreasing returns to scale, but not to all permissible levels of increasing returns to scale. Thus, such theorems as factor price equalization and Rybczynski do not generalize to all real-world levels of VRS.     

THE TRANSFORMATION OF RELIGIOUS LIFE IN RURAL TIBETAN HOUSEHOLDS

<正>Since Tibet Autonomous Region was founded in 1965,the Tibetan people have been in charge of their own affairs under the system of regional ethnic autonomy and religious freedom,with normal religious activities being respected and guaranteed.Taking Namseling Village in Chanang County,Lhoka Prefecture,and Lepu Village in Lhatse County,Shigatse,two common villages in Tibet,as examples,     

A THEORETICAL EXPOSITION OF MIGRATION ENFORCEMENT ON EXISTING MIGRANT AND DOMESTIC HOUSEHOLDS*

ABSTRACT This paper presents a model with a domestic household and a heterogeneous migrant household in arrival timing. The domestic and documented migrant households divide their one unit of time between lobbying for/against immigration enforcement expenditures and employment. The analysis shows that an increase in public dislike for undocumented workers lowers domestic and existing migrant households private investment in own child education. It also causes average public expenditures on education to fall and leads to a negative impact on the educational outcomes of all households.     

高新技术产业布局特征分析

影响高新技术产业布局的区位因子主要是知识、技术、资金和信息。地方政府对高新技术产业的扶持因素和对外开放条件对高新技术产业区位选择的影响越来越大。高新技术产业区位具有智力密集、良好的外部发展条件、对外开放度高和交通方便、生产和生活环境质量相对较高、位于大中城市等特征。高新技术产业布局存在着区域集聚与扩散两种过程。     

THE SHORT-RUN AND LONG-RUN FACTOR-MARKET CONSEQUENCES OF IMMIGRATION TO THE UNITED STATES*

ABSTRACT. This paper applies the production-theory approach to assess the impact on domestic wages and employment of immigration to the United States. Inputs are disaggregated between recent immigrants, non-recent immigrants, native workers, and capital. Census cross-sectional data for 1980 and for 123 metropolitan areas are used. Empirical estimates are reported for alternative functional forms with special attention devoted to required curvature conditions which have frequently been violated in previous work. Elasticity estimates are reported for alternative settings, including for the short run where we view domestic factor prices as given and the long run where we treat them as flexible.
