WHAT DRIVES THE URBAN WAGE PREMIUM? EVIDENCE ALONG THE WAGE DISTRIBUTION

This paper aims at disentangling the role played by different explanations on the urban wage premium along the wage distribution. We analyze the wage dynamics of migrants from lower to higher density areas in Italy, using quantile regressions and individual data. The results show that unskilled workers benefit more from a wage premium accruing over time, while skilled workers enjoy a wage premium when they migrate as well as a wage increase over time. Further, we find that for unskilled workers the wage growth over time is mainly due to human capital accumulation in line with the “learning” hypothesis, while for skilled workers the wage growth is mainly explained by the “coordination” hypothesis, i.e., cities enhance the probability of better matches between workers and firms.     

Spatial and social mobility

This paper analyzes the relationship between spatial mobility and social mobility. It develops a two‐skill‐type spatial equilibrium model of two regions with location preferences where each region consists of an urban area that is home to workplaces and residences and an exclusively residential suburban area. The paper demonstrates that relative regional social mobility is negatively correlated with segregation and inequality. In the model, segregation, income inequality, and social mobility are driven by differences between urban and residential areas in commuting cost differences between high‐skilled and low‐skilled workers, and also by the magnitude of taste heterogeneity.     

Cottages and the Country House: Power,Paternalism and Protest in Elsecar

In the period c.1790 to 1870, the small rural hamlet of Elsecar, near Barnsley, was transformed into an extensive industrial village, with a thriving economy based on iron and coal. Most of this development was instigated, controlled and financed by the local landowners, the 4th and 5th Earls Fitzwilliam. As well as being passionately interested in the practicalities and potential of industrial development, the Earls also looked to the welfare of their workers, providing a wealth of benefits including pensions, sick pay and purpose-built industrial housing. Using a historical approach based on a variety of source material, this paper explores the Earls’ provision of workers’ housing as a way in which to consider wider themes of power, control, inequality and resistance as they were expressed both in the physicality of the houses themselves, and in the cultural meanings which were attributed to them by contemporary observers. The paper argues that workers’ housing functioned as a visible embodiment of power relationships within Elsecar and, because of this, it continues to have a significant resonance in the modern world.     

MIGRATION,SKILL FORMATION,AND THE WAGE STRUCTURE*

ABSTRACT We analyze the impacts of migration and of labor market integration on the distribution of skills and the wage structure in both the short and the long run. To do so, we develop a framework where workers have heterogeneous skills and where in‐migration expands the range of available skills in the economy. In the short run, this expansion leads to productivity gains, which may more than offset the negative endowment effects of a larger labor supply so that all workers may be better off. In the long run, in‐migration impacts wages further by altering the workers' incentives to acquire skills, thereby affecting the wage structure indirectly by changing the economy's skill composition. Since the short and the long‐run effects of in‐migration on wages may differ, compositional changes may be an important element to take into consideration. A numerical illustration calibrated on U.S. data suggests that the immigration of skilled workers negatively affects the incentives for domestic skill formation, thereby suggesting that endowment effects dominate externalities. We finally extend the model to cope with the simultaneous impacts that migration and skill formation have on the host and the source region, and we show that more migration increases wage disparities and the skill gap across regions.     

Problems of Providing Siberia with Manpower

Continuing net out-migration from Siberia produces a manpower supply problem that must be resolved if the regions's economic development is to be pursued. A high rate of labor turnover tends to raise the costs of industrial development and to lower the skill levels of workers as skilled labor leaving Siberian cities for other parts of the USSR is replaced by untrained manpower from the Siberian countryside. Wage differentials in effect in Siberia have been effective in attracting manpower from the Western regions for short periods of time, but have not stimulated permanent settlement. In the view of the authors, new arrivals can be induced to settle down in Siberia only if the adverse impact of the Siberian environment can be compensated by a level of housing and services that is superior to those available elsewhere in the Soviet Union. The significant element is housing, which should receive particular attention in future investment programs. Northern development within Siberia poses the additional problem of physical acclimatization.     

SPATIAL DIFFERENTIATION OF POPULATION DEVELOPMENT IN A DECLINING REGION: THE CASE OF SAARLAND

We increasingly understand the causes of population decline: these can be, among others, processes of deindustrialization, decreasing fertility or the succession of a city through the stages of urban life as the city matures. However, we are still insufficiently able to explain why differences still exist between cities within regions experiencing the same macro‐processes and between cities of the same “level of maturity”. This research addresses this intra‐regional differentiation in population development in the declining former mining region of Saarland (Germany). Quantitative and qualitative analysis reveals that the differentiation in current decline stems from (1) the differentiated population development trajectories of the past, with a massive population boom followed by an aged and declining population in the industrial municipalities; and (2) the spatial distribution of amenities over the region; and (3) the spatial distribution and accessibility of housing opportunities steering migration flows. The latter are not necessarily concentrated in those areas that are attractive. Rather, the distribution of these housing opportunities strictly follows the planning logic of the supra‐local institutional framework, with a concentration of housing within easy access of major transportation infrastructure and in larger centres. The case study thus reveals that the mechanisms behind this intraregional differentiation are much more complex than often portrayed in the urban development and decline debate.     

LOCATIONAL SIGNALING AND AGGLOMERATION

Agglomeration can be caused by asymmetric information and a locational signaling effect: The location choice of workers signals their productivity to potential employers. The cost of a signal is the cost of housing at that location. When workers' marginal willingness to pay for housing is negatively correlated with their productivity, only the core‐periphery (partially stratified) equilibria are stable. When workers' marginal willingness to pay for housing and their productivity are positively correlated, there is no core‐periphery equilibrium. The urban wage premium is explained when there is a core‐periphery equilibrium. Furthermore, location can at best be an approximate rather than a precise sieve for high‐skill workers.     

THE EFFECT OF PROPERTY TAX RATE DIFFERENTIALS ON SINGLE-FAMILY HOUSING STARTS IN WISCONSIN, 1978–1989*

ABSTRACT. A pooled cross-section time-series approach is used to test the hypothesis that differences in property tax rates between and across regions exert an excise-tax impact on housing starts. Synthesizing the research regarding property tax incidence on housing markets and residential location with that of regional housing studies, an empirical model that allows for inter- and intraregional influences on housing starts is developed. Using county data from Wisconsin over a twelve-year span, I find that property tax rate differentials have a negative effect on the construction of single-family houses.     

SKILL POLARIZATION IN LOCAL LABOR MARKETS UNDER SHARE‐ALTERING TECHNICAL CHANGE

This paper considers the “share‐altering” technical change hypothesis in a spatial general equilibrium model where individuals have different levels of skills. Building on a simple Cobb‐Douglas production function, our model shows that the implementation of skill‐biased technologies requires a sufficient proportion of highly educated individuals. Moreover, when technical progress disproportionately replaces middle‐skill jobs, the local distribution of skills will exhibit “fat‐tails,” where the proportion of both highly skilled and low‐skilled workers increases. These and several other predictions of the model are consistent with recent existing evidence, and avoid some major criticism against the “canonical” CES framework.     

Elastic labor supply and agglomeration

This study analyzes the interplay between the agglomeration of economic activities and interregional differences in working hours, which are typically longer in large cities, as they are normally more developed than small cities. For this purpose, we develop a two‐region model with endogenous labor supply. Although we assume a symmetric distribution of immobile workers, the symmetric equilibrium breaks in the sense that firms may agglomerate when trade costs are intermediate and labor supply is elastic. We also show that the price index is always lower, while labor supply, per capita income, real wages, and welfare are always higher in the more agglomerated region.     

The Politics of Crisis: Deconstructing the Dominant Narratives of the Housing Crisis

This paper considers how dominant narratives of the housing crisis, since the 2008 banking crisis in England, have been created and what actions taken in its name. The paper deconstructs the term “crisis”, highlighting that its meaning has evolved from a critical moment to a protracted narrative which must be understood historically. Through discourse analysis into housing and party political policy, media and think tank reports, we argue that the employment of housing crisis by the government and others perceives it as an outcome of housing supply constraints and over-regulation—narratives that have justified subsequent policy actions aimed at propping up the housing and financial systems, opening new avenues for housing commodification, deregulation and financialisation and reproducing crisis anew. However, we note that these narratives can also break down and space can be created for the articulation of new narratives which refocus housing crises as emerging from inequality and class divisions.     

THE EFFECTS OF TRADE WITH DEVELOPING COUNTRIES ON THE REGIONAL DEMAND FOR SKILL IN THE U.S.: EVIDENCE FROM COUNTY DATA*

ABSTRACT Using county‐level data from the 1980s and 1990s and a county‐level trade measure that incorporates the county's industrial mix and patterns of international trade across industries, I provide new evidence that trade with developing countries raises the demand for skill and the skill premium in the U.S. Consistent with Heckscher–Ohlin, I find that trade driven by differences in factor endowments has an economically significant impact on local labor markets. The evidence suggests that when trade with developing countries rises, counties with higher skill endowment and greater employment in industries with larger trade shares experience greater relative demand for high‐skilled labor.     

Does the Structure of an Urban System Affect Income Disparities?

In this paper I analyze the impact of basic training and specialized training on the distribution of skill, income disparity, social welfare, and on the structure of a decentralized specialized city system. This is done in a spatial general-equilibrium model of a closed economy producing a single consumption good. The economy is populated with a continuum of unskilled labor with potential heterogeneous ability. The only consumption good can be produced by specialized technology or by general technology. Specialized technology requires specialized training that enables each worker to transform his potential ability into productivity. General technology requires basic training that enables all workers, independent of their potential ability, to produce the good at a constant marginal product. In this framework I show that such an equilibrium exists uniquely and is efficient. Then I characterize the conditions that lead to a different distribution of skills, a different system of cities, and generate income disparity endogenously. Thus, the paper presents a link among income disparities, social welfare, and the structure of an urban system that is new to this literature.     

Reflecting on a Decade of Australian Social Housing Policy: Changes in Supply and Geography, 2001–2011

This paper compares the intent of three Australian social housing policy interventions in the decade to 2011 with outcomes shown in time series data from the Australian Bureau of Statistics Census. The three policy interventions are the supply stimulus that occurred in 2009 with funding to construct almost 20 000 new social housing dwellings by 2012, the push to diversify social housing supply through the transfer of public housing stock to community not‐for‐profit housing providers, and the physical renewal of public housing estates to reduce concentrations of social deprivation. Its aims are threefold: to understand how the supply and geography of social housing dwellings has changed over the past decade; to relate these changes to the objectives of social housing policy in the time period; and to identify issues for the future of social housing in Australia emerging from identified disparities between policy rhetoric and supply reality. The paper employs quantitative analysis of social housing supply for all of Australia and mapping of social housing supply changes in the east‐coast mainland state capital cities. This analysis reveals the overall stagnation of social housing supply in Australia over the previous decade, combined with evidence of stock loss in areas of renewal in some cities.     

Immigration and Welfare for the Host Economy with Imperfect Competition

In the literature, the beneficial result of immigration to the host country relies on the assumption of perfect competition in the goods market. However, for an economy characterized by imperfect competition, immigration of unskilled workers can be welfare-reducing. The entry of skilled workers is nevertheless welfare-enhancing under a plausible factor-intensity condition.     

KNOWLEDGE SPILLOVERS,ABSORPTIVE CAPACITY,AND SKILL INTENSITY OF CHILEAN MANUFACTURING PLANTS*

ABSTRACT Knowledge spillovers are an important source of economic growth. In this study, we identify a mechanism through which knowledge spillovers occur among plants in the Chilean manufacturing industry. A plant‐level production function is estimated with the absorptive‐capacity hypothesis, that is, employment of skilled workers is a key channel through which knowledge is transmitted across plants. Results show that a plant's productivity from spillovers increases with its skill intensity, which is measured by the share of skilled workers in total employment. We also find that plants in a region with a large knowledge stock increase their skill intensity to benefit more from spillovers. Our results suggest that an increase in regional knowledge stock is the most effective policy to improve a plant's productivity. However, policies that encourage a plant to employ high skill‐intensive production also enhance its productivity.

Regional inequality in the U.S.: Evidence from city-level purchasing power

Using quarterly data for 42 products over the period from 1990 to 2015, we find that there has been a large and growing dispersion of purchasing power across U.S. cities since 1990 and the dispersion varies widely across products. We also find that total factor productivity shock precedes or predicts the rise in regional inequality of purchasing power. We view that the growing regional inequality found in the purchasing power among U.S. cities might have proceeded after nationwide productivity shocks mainly by the cities with higher share of skilled workers through the products with more flexible price adjustments.     

北京市区轨道交通对周边住房租赁价格的影响分析

基于北京市六环内住房租赁样本的交易数据,本文以北京地铁为例,采用空间回归模型实证探讨轨道交通对合租和整租这两种不同方式下的住房租赁价格的影响。结果表明：①基于轨道交通的就业可达性对于租赁价格会产生显著的增值效应,租客愿意为就业可达性较好的住房支付溢价租金。②地铁站点密度对整租的租赁价格具有正向影响,对合租无显著影响,而地铁换乘线路变量未对租赁价格产生显著影响。③轨道交通对合租和整租住房租赁价格的影响随着距离增加呈现差异化的演变规律。合租方式的租赁价格的影响随着实际路网距离的增加呈现单调递减,距站点500m范围内影响最大;而整租方式呈现倒“U”形变化,在500-1500m范围内增值效应最大。针对研究结果,建议政府加大租赁住房供给的同时要充分考虑轨道交通要素,精准施策以实现公共资源的空间高效配置。
