PRODUCTION FUNCTIONS AND THE DISAGGREGATION OF LABOR INPUTS IN MANUFACTURING PLANTS*

ABSTRACT. This paper investigates the assumption of homogeneous labor inputs underlying the production functions in many regional models. The results indicate that nonproduction and production labor within manufacturing plants are not strongly separable, and the homogeneous labor assumption is not therefore appropriate. Hence, regional models need to take this into account in order to give reliable results. Differences between industries provide useful additional insights into their labor and capital relationships.     

REGIONAL LABOR PRODUCTIVITY IN THE NETHERLANDS: EVIDENCE OF AGGLOMERATION AND CONGESTION EFFECTS*

ABSTRACT This paper studies the impact of localization, urbanization, and diversification on regional labor productivity levels and growth. We find substantial effects, accounting for roughly half of the explained variation in the labor productivity differences within the Netherlands in the 1990s. Diversification, urbanization, and localization effects are significant and positive for productivity levels. These levels appear cointegrated. The error correction specification of productivity growth surprisingly reflects negative agglomeration effects. From the theoretical model it follows that congestion effects must have taken precedence over agglomeration effects during this period. Both agglomeration and congestion effects are dampened by job density in neighboring regions. Finally, policy simulations with the estimated model show that spatial concentration is more harmful to national productivity growth than spatial dispersion.     

UNDOCUMENTED IMMIGRANTS AND THE WELFARE STATE: THE CASE OF REGIONAL MIGRATION AND U.S. AGRICULTURAL LABOR

A common perception is that immigrants, including illegal immigrants, use disproportionate public aid and select locations based on characteristics of services offered. This paper asks to what extent geographic clustering of undocumented immigrant agricultural laborers in the U.S. is correlated with take‐up of public aid broadly defined. Evidence from a nationally representative farmworker survey does not support welfare migration for undocumented immigrants, who have been previously unidentifiable in the literature. The paper, therefore, challenges existing notions of welfare migration by illegal immigrants that have inspired state‐level public policy initiatives.

ON THE IMPACT OF LABOR MARKET MATCHING ON REGIONAL DISPARITIES*

ABSTRACT We propose a model where imperfect matching between firms and workers on local labor markets leads to incentives for spatial agglomeration. We show that the occurrence of spatial agglomeration depends on initial size differences in terms of both number of workers and firms. Allowing for dynamics of workers' and firms' location choices, we show that the spatial outcome depends crucially on different dimensions of agents' mobility. The effect of a higher level of human capital on regional disparities depends on whether it makes workers more mobile or more specialized on the labor market.     

THE IMPACT OF SPECIFIC-SECTOR CHANGES IN EMPLOYMENT ON ECONOMIC GROWTH, LABOR MARKET PERFORMANCE AND MIGRATION

ABSTRACT.  It is common in empirical regional economics to use total employment as an explanatory variable while investigating issues such as the level and distribution of income and migration. This paper argues that sector-specific changes in employment and labor market performance can have different effects on economic growth, the collection of tax revenue, migration, and the level and distribution of household income. As such, it is important to model sectors separately. We find that expansions in employment opportunities for a high-wage sector such as computer manufacturing or bioengineering, a medium-wage sector manufacturing, and the lower-wage sector of retailing have differing economic consequences for a small city. We use a data intensive computable general equilibrium model to obtain these results.     

POLLUTION ABATEMENT EXPENDITURES AND REGIONAL MANUFACTURING ACTIVITY*

ABSTRACT. Using a sample of 63 SMSAs for the years 1974, 1978, and 1982 I find weak support for the argument that environmental regulations retard economic activity. Regression analysis of the relationship between per unit total and air pollution abatement expenditures in the manufacturing sector of these SMSAs and manufacturing employment and earnings levels reveals that these associations are negative but that the magnitudes are relatively small. For example, 10 percent higher per unit total pollution abatement costs are associated with, on average, 1064 fewer manufacturing workers (0.17 percent of total regional employment) in Sun Belt SMSAs during 1982.     

THE BAM: LABOR,MIGRATION AND PROSPECTS FOR SETTLEMENT

The construction of the showcase Baikal-Amur Mainline (the BAM), which spans over 2,000 miles of unsettled, desolate territory, provides an excellent opportunity to study labor management and organization in a centrally planned economy, and illustrates the interplay of central planning with the relatively unhindered migration of workers. Significantly, in the face of a shrinking labor force, the USSR attracted thousands of young people to Siberia to work on the BAM. Now that the rail line is in place, the more difficult task will be to entice workers to settle in the BAM zone. Until the Soviet Government makes a firm commitment to improving the quality of life in Siberia, prospects for settling the BAM region remain uncertain.

ANALYSIS OF THEORETICAL,METHODOLOGICAL AND EMPIRICAL RESEARCH IN THE JOURNAL OF REGIONAL SCIENCE*

ABSTRACT. This paper examines the impacts of JRS articles in the areas of theory, methods and empirical analysis, as represented by subsequent citations reported in the Social Sciences Citation Index. A model relating the mix of theoretical, methodological and empirical research published in the JRS to subsequent citations is estimated. The time distribution of theoretical and empirical citations also indicates that the knowledge diffusion process in these two areas may be segmented.

SCALE ECONOMIES,REGIONAL EXTERNALITIES,AND THE POSSIBILITY OF UNEVEN REGIONAL DEVELOPMENT*

ABSTRACT. This paper presents a model of regional development which attempts to explain differing patterns of growth in two regions. The model is an extension of Krugman's model of uneven development, but it incorporates not only scale economies within each region but also regional externalities across the regions. Depending on relative magnitudes of net scale economies of the two regions, the model entails different regional development patterns: uneven development, stable or joint development, or a mix of the two. The novel feature of the present model is that different regional development patterns can be explained within the same analytical framework.
