Current Literature Bibliography

Two specialists on the electoral geography of post-Soviet Russia analyze spatial patterns emerging from parliamentary elections and a constitutional plebiscite held in December 1993. In addition to spatial patterns in the election and plebiscite returns, reference will be made in the analysis to underlying socioeconomic factors believed to influence voters and to interregional variations in voter characteristics. The extent to which such factors and variations are associated with voter preference, party affiliation, and voter turnout is tested using standardized regression techniques. Implications of current patterns for important forthcoming elections are explored. 5 figures, 5 tables, 20 references.     

RETURNS TO SCALE AND REGIONAL GROWTH: THE STATIC‐DYNAMIC VERDOORN LAW PARADOX REVISITED*

ABSTRACT It has long been an article of faith amongst regional economists that increasing returns to scale are necessary to explain the punctiform location of economic activity and population. However, there is no consensus in the empirical literature over whether returns to scale are constant or increasing. A notable example of this lack of agreement is provided by the static‐dynamic Verdoorn law paradox. While the dynamic Verdoorn law (specified using growth rates) yields estimates of substantial increasing returns to scale, the static Verdoorn law (specified using log‐levels) indicates only the presence of constant returns to scale. In this paper, we explain the static‐dynamic Verdoorn law paradox by showing that estimates of returns to scale obtained using the static law are subject to a spatial aggregation bias, which biases the estimates towards constant returns to scale. We illustrate our arguments by means of simulation exercises. The results obtained hold general lessons for applied economic analysis using spatial data.     

A SPATIAL ANALYSIS OF SECTORAL VARIATIONS IN RETURNS TO EXTERNAL SCALE

ABSTRACT.  This paper reports results of spatially explicit analyses of external scale effects across a variety of sectors, including manufacturing. Using data from New England counties, earnings are found to exhibit increasing returns to urbanization in every sector. Returns to sectoral localization are mixed, however, with increasing returns in one sector, constant returns in five sectors, and decreasing returns in two sectors. External scale effects are fairly confined in their spatial extent, with only retailing and services particularly marked by spillover effects from neighboring counties.

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.     

SPATIAL MOBILITY AND RETURNS TO EDUCATION: SOME EVIDENCE FROM A SAMPLE OF FRENCH YOUTH*

ABSTRACT This study re‐evaluates the returns to geographic mobility and to the level of education taking into account the interaction between these two variables, and using the distance covered as a proxy for migration costs. We have at our disposal an original French database that permits precise calculation of the distance between the place of education and the location of first employment. For men, we find decreasing returns to spatial mobility as the distance covered rises and increasing returns to mobility with higher levels of education. The marginal returns to spatial mobility for women are lower across the board.     

Rubber plantations and their implications on gender roles and relations in northern uplands Vietnam

Abstract

In recent years, rubber plantations have been strongly promoted in the northern uplands of Vietnam–especially in the northwest, where it is an ill agro-ecological fit–with an aim to improve ethnic minority livelihoods and to modernize peasants by transforming them into rubber workers. A large area of land has been taken away from farmers to make way for rubber plantations. This land acquisition and agrarian transformation have impacted local people and their livelihoods in various ways. Drawing on ethnographic research, in combination with interviews with authorities and studying related documents, this article focuses on the gendered consequences of rubber plantation in northern uplands Vietnam. It argues that the process of becoming a rubber worker and adapting to the new way of living has indeed added new roles and responsibilities for women. At the same time, it has undermined men’s values and reshaped gender relations both within and outside the home.     

THE LOCATION THEORY OF THE PLANTATION*

ABSTRACT This paper develops a method for studying noninfinitesimal operational units, with the Thünen location and land use model. With constant returns to scale and perfect divisibility of nonland inputs, all operational units would occupy only a point on the landscape. The present model uses increasing returns to scale to generate large operational units, called “plantations” and studies the comparative statics. The setting of the model is an agricultural operation in which some processing of raw crop must be conducted prior to shipment to market. The processing is assumed to have increasing returns to scale.     

Urbanization patterns: European versus less developed countries

This paper develops a model in which the interaction between transport costs, increasing returns to scale, and labor migration across sectors and regions creates a tendency for urban agglomeration. Demand from rural areas favors urban dispersion. European urbanization took place mainly in the 19th century, with higher costs of spatial interaction, weaker economies of scale, and a less-elastic supply of labor to the urban sector than in less developed countries (LDCs) today. These factors could help explain why primate cities dominate in LDCs, whereas a comparatively small share of urban population lives in Europe's largest cities.

A Hostile Takeover of Nature? Placing Value in Conservation Finance

Conservation finance is a nascent field that claims to “deliver maximum conservation impacts, while, at the same time, generating returns for investors” (Credit Suisse/WWF). While geographers have questioned the ability of conservation finance to play a significant role in international biodiversity conservation, an emerging cohort of boutique private equity firms are actively generating returns on North American conservation projects. This raises the question: how are these firms generating profits, and in turn, returns for their shareholders? Drawing from a Marxian understanding of finance as redistributive, I argue that these firms are generating profits through a process similar to a corporate hostile takeover. Using the examples of ranchland and timberland investment in the United States, I show that (1) the materialities and historical geographies of these landscapes play a crucial role their monetization, and (2) shareholder returns are generated through a combination of traditional real estate sales and revaluations, public monies, and commodity production.     

Mind the Gaps: The Evolution of Regional Earnings Inequalities in the U.K., 1982–1997

In this paper we apply earnings equations for U.K. regions over 1982–1997. We find evidence of rapid convergence across regions regarding the determinants of individual wages (i.e., regional fixed-effects, gender gaps, and returns to education and experience). In contrast, data on average regional earnings point to a worsening of U.K. regional inequalities and a rise in the North-South gap. Education accounts for most of the discrepancy between aggregate divergence and disaggregated convergence. First, London gained because its workforce became relatively more educated over the period. Second, returns to education increased nationwide, which favored the most educated regions (i.e., London). Third, returns to education were initially lower in London but they (partially) caught up with the rest of the country. Had returns to education and their distribution across U.K. regions remained stable over the period, the U.K. North-South divide would have decreased.     

Rubber Erasures,Rubber Producing Rights: Making Racialized Territories in West Kalimantan,Indonesia

This article makes connections between often‐disparate literatures on property, violence and identity, using the politics of rubber growing in West Kalimantan, Indonesia, as an example. It shows how rubber production gave rise to territorialities associated with and productive of ethnic identities, depending on both the political economies and cultural politics at play in different moments. What it meant to be Chinese and Dayak in colonial and post‐colonial Indonesia, as well as how categories of subjects and citizens were configured in the two respective periods, differentially affected both the formal property rights and the means of access to rubber and land in different parts of West Kalimantan. However, incremental changes in shifting rubber production practices were not the only means of producing territory and ethnicity. The author argues that violence ultimately played a more significant role in erasing prior identity‐based claims and establishing the controls of new actors over trees and land and their claims to legitimate access or ‘rightfulness’. Changing rubber production practices and reconfigurations of racialized territories and identity‐based property rights are all implicated in hiding the violence.     

PUBLIC CAPITAL, REGIONAL OUTPUT, AND DEVELOPMENT: SOME EMPIRICAL EVIDENCE

ABSTRACT The goal of our paper is to provide direct estimates of the association between public capital and regional output. This is made possible by the construction of a data series which measures public capital at the state level.
The relation between public capital and other productive factors is tested using a translog production function. Our results show that labor and public capital are complementary inputs, and that public capital exhibited diminishing returns. We also consider restrictions on the translog formulation. Linear homogeneity is rejected in all cases, and the Cobb-Douglas specification is rejected for the manufacturing and all sectors categories.     

Do Workers Benefit from Industrial Agglomeration?*

Abstract. This paper provides an empirical investigation of the advantages accruing to workers in industrial clusters. Using a unique data set based on the Cluster Mapping Project of the Italian National Statistical Institute, we examine whether industry agglomeration leads to wage and labor mobility differentials. We estimate complete Mincerian wage equations, investigating whether returns to seniority and education are a possible source of differentiation. We find that working in an industrial cluster reduces the returns to education, does not affect the returns to seniority, and does not provide average wage premia. On the other hand, industrial agglomeration positively affects the likelihood of being employed, of starting a business, and of making a transition from payroll employment to entrepreneurship; it also increases blue‐collar worker mobility across jobs.     

GOVERNMENT QUALITY AND THE ECONOMIC RETURNS OF TRANSPORT INFRASTRUCTURE INVESTMENT IN EUROPEAN REGIONS

Transport infrastructure investment is a cornerstone of growth‐promoting strategies. However, the link between infrastructure investment and economic performance remains unclear. This may be a consequence of overlooking the role of government institutions. This paper assesses the connection between regional quality of government and the returns of different types of road infrastructure in the regions of the European Union. The results unveil the influence of regional quality of government on the economic returns of transport infrastructure. In weak institutional contexts, investment in motorways—the preferred option by governments—yields significantly lower returns than the more humble secondary road. Government institutions also affect the returns of transport maintenance investment.     

Migration and Occupational Choice among Young Labor Force Entrants: A Human Capital Model

Interregional variations in the conditions for entering the labor force are investigated by analyzing interdependencies between migration behavior and occupational choice for young labor force entrants. The human capital framework indicates that occupational choice depends on the costs and returns associated with entering various occupations, and that interregional variation in these costs and returns is a major reason for migration. Occupational choice and migration behavior will be interdependent if the costs and returns for particular occupations vary over local labor markets, relative to other occupations, and patterns of interdependence between the two decisions are analyzed, using a model of the joint choice of occupation and location. An empirical analysis of occupational choices and migration behavior for young people who entered the U.S. labor force in the 1975–80 period indicates that the odds for entering professional or managerial occupations varied with origin and migration behavior in systematic ways.

Theory of Comparative Advantage: Do Transportation Costs Matter?

In this paper we present a formal analysis that incorporates returns to transportation into a Ricardian framework to predict trade patterns. The important point gained from this analysis is that increasing returns to transportation, coupled with appropriate distances between trading partners, can be shown to reverse Ricardian predictions even when there are no international differences in tastes, technology, or factor endowments. Additional gains from trade may emerge from reductions in aggregate delivery costs owing to scale economies.     

A study of signal statistics of VHF radar echoes from clear air

Signal statistics of VHF radar returns from vertical pointing observations of the clear air are investigated. In particular, the signal signature, its Doppler spectrum and statistical distribution are examined. It is found that the most important factors that characterize the statistics of the signals are the width of the spectrum and the Nakagamim-coefficient for the intensity distribution. Using these factors as criteria, two types of signals are found. One corresponds to volume scattering arising from turbulence or multiple thin laminae or sheets. The other corresponds to return from a single sheet. Examples of the different scattering/reflection processes will be shown. Numerical modeling is used to simulate the scattering/reflection processes. From the simulation, it is demonstrated that echo signals from some range gates are consistent with the picture of reflection from a single, diffuse sheet, causing focusing and defocusing of the signals.
