Do Urban Agglomeration Effects and Household Amenities have a Skill Bias?*

There are several hypotheses why urban scale affects wages. Most focus on agglomeration economies that increase labor demand, especially for high‐skilled workers (e.g., dynamic externalities stress knowledge transfers, and imply the urban wage gap favors skilled workers). Others stress urban amenities that increase labor supply and decrease wages. Amenities should have a stronger influence on affluent households if they are normal goods. By examining whether urban‐scale affects net returns to education, it can be determined whether skilled workers are influenced more by urban productivity or amenities. Empirical results suggest net returns to education decline with urban scale, implying a key role for urban amenities in affecting skilled workers.

GENERAL EQUILIBRIUM OF SPATIAL PRODUCT AND LABOR MARKETS*

ABSTRACT A simple general equilibrium model relates spatial product markets and spatial labor markets. The firm is treated as being a spatial monopolist or as a Löschian competitor in the output market and as a spatial monopsonist in the labor market. Derived free spatial demand and free regional labor supply are defined, and their properties examined. The model provides the framework for analyzing the impact of a technological improvement in labor productivity on the structure of the spatial markets. The impact of entry on spatial labor supply is an important determinant of whether or not entry lowers wages and raises output prices. Unlike the spaceless competitive paradigm, zero-profit long-run equilibrium can occur in a space economy under conditions of increasing returns to scale.     

AMENITIES VERSUS LABOR MARKET OPPORTUNITIES: CHOOSING THE OPTIMAL DISTANCE TO MOVE*

ABSTRACT. A recent debate in the regional economics literature has focused attention on the motivation behind an individual's decision to migrate. Human-capital migration models emphasize labor market disequilibria whereas alternative (hedonic) migration models stress households’altered demand for nontraded goods. In this paper, we test the relative importance of these two possible motivations for moving between metropolitan areas. We use an intercity hedonic model to decompose wages into equilibrium and disequilibrium components. We then compare the separate influences of amenities and the disequilibrium component of wages on the distance moved between two metropolitan areas. Our findings indicate that both economic factors and amenity differentials are significant factors in explaining regional migration.     

THE EFFECT OF YOUTH POVERTY RATES AND MIGRATION ON ADULT WAGES

We created a migration and earnings history from the National Longitudinal Survey of Youth to analyze the effects of youth county poverty rates on the adult earnings of white male migrants. We estimate a log wage equation that includes human capital measures, migration types, county poverty rates, and a rural–poverty rate interaction variable. Growing up in a rural county has a negative impact on adult wages independent of youth county poverty rates, but the rural effect is significantly greater for those who grew up in high poverty counties. Youth county poverty rates indirectly affect wages through the returns to migration.

The Geography of Economic Development and Racial Discrimination in Brazil

This study investigates the relationship between unequal resource and population distribution and racial wage inequality in Brazil. Using sample data from the 1980 Brazilian census, monthly wages were estimated for white and Afro-Brazilian men working in nine metropolitan areas. Estimates showed that racial disparities in wages existed across all regional labour markets. Regression-based decomposition analysis found that a substantial portion of the racial wage gap was due to discrimination (unequal pay), while estimates of the magnitude of labour market discrimination indicated considerable variation by geographical area. Discrimination was higher in the predominantly white and highly developed areas of the South than in the former slave and underdeveloped regions of the Northeast.

The Demand for and Supply of Technical Information and Analysis in State Legislatures

With states making more substantive decisions in technically complex policy areas, the capacity of state legislatures to gather and use technical information and analysis is crucial. Applying a "market" metaphor, the article examines the demand for and the supply of technical information and analysis in state legislatures. The demand among legislators and staff is widespread and increasing, and the supply is varied in origin, importance, and quality. Reliance on sources external to the legislature—usually perceived as biased—is related to a lack of professionalization in legislatures, although the level of satisfaction in the available technical information and analysis is not. Identifiable barriers on both the demand side and the supply side prevent better use of technical information and analysis. There are ways to strengthen the relationship between state legislatures and a broad array of sources, as well as to educate the legislative consumer of technical information and analysis.     

The commodity crisis of the 1970s: scarcity,vulnerability and the West German metal supply

ABSTRACT

The 1970s were a period marked by price hikes and fluctuations in the commodity markets, both of which had considerable economic and political repercussions. Although this refers to almost all kinds of raw materials, the case of oil dominates the memory. Metals, by contrast, have received little attention despite their crucial importance for both industrialized consumer states and ore-exporting developing countries. This article develops three main points. First, by highlighting the global metal markets from the late 1960s to the early 1980s it contextualizes the oil-price shock and points out the interactions between the markets for energy and other raw materials. Second, the article aims to draw attention to the sense of crisis in Western industrialized countries regarding their metal supply during this period. This is a topic which has been overshadowed by the case of oil, but which nevertheless deserves study, also because of the parallels to recent developments between 2004 and 2011. Third, the article analyses how notions of resource scarcity, vulnerability and crisis were constructed despite the fact that the commodity crisis proved to be a merely anticipated crisis with high and volatile prices, but no long-term disruptions of supply. Within this article West Germany serves as a case study for highly industrialized, import-dependent countries. The focus is on non-ferrous metals like copper, nickel and aluminium.     

Poverty Alleviation Programmes In Rural India: An Assessment

ABSTRACT The Planning Commission estimated a sharp reduction of poverty during the early 1980s, which it attributed largely to the poverty alleviation strategy followed during the Sixth Plan. Specifically, it was claimed that the Integrated Rural Development Programme (IRDP) was responsible for a substantial reduction in rural poverty. This claim is critically evaluated here. Drawing upon the results of an applied general equilibrium model, selected anti-poverty interventions are compared from a macro perspective. Noting the incentive and information-related problems, some key issues in designing anti-poverty interventions are addressed. Section I reviews changes in rural poverty at the all-India level. Section II explores the relationship between rural poverty, agricultural production and (consumer) prices. Distinguishing between transitory and persistent poverty, alternative measures of persistent poverty are presented in Section III. A case is then made for an interventionist anti-poverty strategy, followed by a brief review (Section IV) of salient features and selected performance indicators of poverty alleviation programmes launched/implemented during the Sixth Plan period. Section V investigates whether these programmes — especially the IRDP — played a significant role in alleviating poverty. Section VI discusses selected anti-poverty interventions and possible design-related reforms; concluding observations are offered in the final section.     

Scale economies and the geographic concentration of industry

In recent empirical literature on spatial agglomeration, manypapers find evidence consistent with location-specific externalitiesof some sort. Our willingness to accept evidence of agglomerationeconomies depends on how well key estimation problems have beenaddressed. Three issues are particularly troublesome for identifyingagglomeration effects: unobserved regional characteristics,simultaneity in regional data, and multiple sources of externalities.Two empirical results appear to be robust to problems createdby the first two issues: (a) individual wages are increasingin the presence of more-educated workers in the local laborforce, which is consistent with localized human-capital externalities,and (b) long-run industry growth is higher in locations witha wider range of industrial activities, which suggests thatfirms benefit from being in more diverse urban environments.Other evidence is supportive of agglomeration effects relatedto regional demand linkages and short-run, industry-specificexternalities.     

A Spatial Price Determination Model for Multi‐Market Heterogeneously Distributed Resources: An Application to Forestry Markets in Sweden

The spatial dimension is a key paradigm in price determination, as attested by recent studies in the literature that highlighted the differential in market behavior between spatial and non‐spatial pricing settings. In this paper, we develop a model of spatial pricing for multi‐market heterogeneously distributed resources, with an application to the Swedish forestry sector. The focus of the model is to estimate the impact of spatial interaction on the demand for resources in terms of resource allocation, competition, and pricing. In its core, the pricing mechanism relies on a supply–demand framework. Using disaggregated data at the gridcell level for forest feedstock supply and harvesting costs in Sweden, we construct regional supply curves for each gridcell assuming a maximum transportation distance to delimit the potential market. Demand nodes are exogenously determined and are adjusted using a distance‐decay model to assess demand pressure across locations. We apply the model empirically to assess the impact on forest feedstock prices of a 20 TWh increase in biofuel production.     

Factors underlying inflation in Russia 2000–2015

Abstract

This paper examines the problem of continuing inflation in Russia in the period from 2000 to 2015. Although factors causing high inflation changed during this period, such factors as money supply, wages, gas and electricity prices, and ruble exchange rate have been essential factors when analyzing inflation in Russia. This paper focuses on gas and electricity prices that represent state-regulated prices in natural monopoly sectors and that have been factors of price increases specific to Russia. They have been raised by the state in order to narrow the gap between their domestic and international prices. It is suggested that there was a turnaround in 2008 when the role of each inflation factor changed significantly. Concerning the rebound of inflation rate since 2014, the overwhelming influence of depreciation of the ruble is indicated. Institutional factors such as the monopolistic structure of the economy that have kept the inflation rate high in Russia are also suggested.     

Structural Change,the Social Policy Environment and Female Employment in Turkey

Since the 1970s, a series of demand and supply related changes have led to significant labour market transformations which have brought about a sustained increase in female employment throughout the world. While similar transformations have also been underway in Turkey, the country appears to be one of the rare exceptions to worldwide trends. During the last two decades both female labour force participation and female employment rates have declined at national level. In this article, two sets of questions are posed to explore the factors likely to influence female labour force participation. One set of questions pertains to the society‐specific dynamics of structural change in employment patterns in Turkey, with particular reference to the level and composition of employment in the service sector. A second set of questions is posed to examine labour market relations and the social policy environment in Turkey, and their impact on the demand for and supply of female labour. Current changes in the prevailing policy environment are considered to highlight a certain contradiction in the attitudes of decision makers who seem to be faced with a trade‐off between continuing adherence to conservative patriarchal values and the objectives of increasing labour force participation and combating poverty.     

Migration,Frictional Unemployment,and Welfare‐Improving Labor Policies*

Abstract. Studies have suggested that there exists job search and recruiting friction in urban areas. This paper constructs a two‐sector (rural and urban) model involving this factor and investigates how it affects migration and what the optimal policies should be. An analysis shows that frictional urban unemployment brings about intersector wage differentials and that an economy almost always has distortion in the absence of government intervention. Tax and subsidy policies that remove the distortion are explored. Setting urban wages appropriately is also shown to attain the optimum. Finally, we explore the criterion to judge whether changing urban wages as a policy, such as the minimum wage law, enhances social welfare.     

Women Beneficiaries or Women Bearing the Cost? A Gendered Analysis of the Red de Protección Social in Nicaragua

Conditional Cash Transfer programmes aim to alleviate short‐term poverty through cash transfers to poor households, and to reduce longer‐term poverty through making these transfers conditional on household investment in the health and education of children. These programmes have become increasingly popular with institutions such as the World Bank. However, the need for conditionalities has been questioned on a number of levels, including its necessity: it has been suggested that the cash transfer in itself may be sufficient to secure most of the programme's wider aims. The example of Nicaragua supports this contention, demonstrating that only a small incentive is needed to bring the desired changes in the uptake of education, since this is something prized by the poor themselves. In health, the Nicaraguan case suggests that demand‐side initiatives might not be as important as supply‐side changes that improve the affordability and accessibility of services. The Nicaragua case also highlights the long‐term limitations of applying such programmes in countries with high levels of poverty and low economic growth. A gendered analysis of the programme highlights the fact that women ‘beneficiaries’ bear the economic and social cost of the programme without apparent benefit to themselves or even necessarily to the household in the short or longer term.     

Regulating economic globalization

It is widely accepted that the rising gap in recent years between the global rich and the global poor can be linked to globalization in one way or another, although the strength and causality of the link is debated. Against the backcloth of the havoc wreaked by neo-liberalism and the Washington Consensus, new meta-narratives of global order are emerging to suggest ways of reducing global poverty and inequality. This paper examines two 'Olympian' visions of re-regulation along social democratic lines that propose new scalar arrangements. It evaluates these meta-narratives against another spatial ontology of regulation thrown up by the economy of global flows and networks – an unfolding regime of heterarchical order that is topological, hybrid, decentred and coalitional in its workings. The paper argues that these new 'micro-worlds' of regulation are as significant as, and equivalent to, so-called macro-orders of regulation in influencing global poverty and inequality, that they throw into doubt assumptions of control and reach held by the meta-narratives, and that their rise amounts to a situation of global regulatory excess, rather than, as some have argued, a condition of regulatory deficit or global disorder.     

Spatial distribution of US employment in an urban efficiency wage setting

We analyze whether efficiency wages operate in urban labor markets, within the framework proposed by Ross and Zenou, in which shirking at work and leisure are assumed to be substitutes. We use unique data from the American Time Use Survey (ATUS) that allow us to analyze the relationships between leisure, shirking, commuting, employment, and earnings. We confirm that shirking and leisure are substitutes, and present an estimate of this relationship, representing the only empirical test of the relationship between a worker's time endowment and shirking at work. Our findings point to the existence of efficiency wages in labor markets.     

EXTENDING A SMOOTH PARAMETER MODEL TO FIRM LOCATION ANALYSES: THE CASE OF NATURAL GAS ESTABLISHMENTS IN THE UNITED STATES

This paper extends recent developments in regional growth modeling that use spatial regime switching functions to a count regression model of firm location events. The smooth parameter count model (SPCM) allows for a parsimonious parameterization of locally varying coefficients while simultaneously attending to excess‐zero count events. An empirical application examines natural gas establishment growth between 2005 and 2010. The smooth parameter model appears to outperform a standard zero‐inflated count model. The SPCM may be extended to the location analysis of other industries with the identification of transition variables related to the supply or demand oriented cost structure of the sector.
