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.     

THE INTRAMETROPOLITAN DISTRIBUTION OF R&D ACTIVITIES: THEORY AND EMPIRICAL EVIDENCE*

ABSTRACT. The paper presents a first attempt to unveil the underlying determinants of the geography of R&D labs within contemporary metropolises. To this end, the study builds on the premise of contemporary intraurban location and pricing models, suggesting that intraurban variations in property rents must reflect the imputed location preferences of firms or their workforce, as well as the extent to which local institutional constraints hinder these preferences. Against this background, the study proceeds with the econometric analysis of R&D property rent differentials within Greater Los Angeles. The empirical results indicate that access to research and nonresearch universities, transportation access, access to a host of worker amenities, as well as zoning and other local regulations play a critical role in shaping the intraurban geography of R&D labs.     

THE DETERMINANTS OF RESTRICTIVE RESIDENTIAL ZONING: SOME EMPIRICAL FINDINGS*

ABSTRACT. This study proposes, and finds evidence supporting, the hypothesis that restrictive residential land-use and minimum lot-size zoning are substitute ways of controlling the population intensity of future residential development. In addition, evidence is found linking externality, fiscal and exclusionary objectives to restrictive residential zoning.     

FLEXIBLE TECHNOLOGY IN THE CLOTHING INDUSTRY: SOME EVIDENCE FROM VANCOUVER

This paper provides some preliminary evidence on the impact of flexible equipment on the clothing industry in Vancouver. It is argued that the implementation of these machines is limited to certain sectors of the industry and to specific sections of the labour process in clothing factories. In spite of the limited impact of these machines in Vancouver, the implications of flexible equipment in this manufacturing sector are far-reaching.
Get article fournit des évidences préliminaires sur l'effet de l'outillage maniable sur la confection à Vancouver. L'on dit que la réalisation de ces machines est restreinte à certains secteurs de l'industrie et aux parties précises du processus du travail dans les usines de confection. Malgré l'effet restreintde ces machines à Vancouver, l'implication de l'outillage maniable dans la confection est d'une portée considérable.     

ON THE PLAUSIBILITY OF THE SUPPLY-DRIVEN INPUT-OUTPUT MODEL: EMPIRICAL EVIDENCE ON JOINT STABILITY*

ABSTRACT. This paper addresses the issue of the plausibility of the supply-driven input-output model from an empirical standpoint. We suggest that requiring production coefficients to remain perfectly fixed during an application of the supply-driven input-output model is unnecessarily restrictive given the extensive use of approximation methods in mathematics, economics and regional science. Simulations with the supply-driven version of an input-output table for a representative region are shown to result in changes in the corresponding production coefficients well within conventional tolerance levels.     

THE PUZZLE OF JOB SEARCH AND HOUSING TENURE: A RECONCILIATION OF THEORY AND EMPIRICAL EVIDENCE

Oswald's thesis posits that homeowners should have longer unemployment spells than renters due to restricted mobility, but repeatedly the reverse is found. I contribute to solve this puzzle analyzing both job search intensity and unemployment duration. First, I show that homeowner's mobility constraints have a negative impact on search. Theoretically, it is shown in a search model with moving costs. Using U.K. Labour Force Survey (LFS) data, it is confirmed when considering outright owners, while leveraged owners have the highest search. Second, I find evidence that homeowners select search methods associated with shorter unemployment spells, suggesting that they search more efficiently.     

SPATIAL HETEROGENEITY IN KNOWLEDGE,INNOVATION, AND ECONOMIC GROWTH NEXUS: CONCEPTUAL REFLECTIONS AND EMPIRICAL EVIDENCE

By drawing on the Schumpeterian distinction between invention (i.e., new ideas and knowledge creation) and commercialization of new ideas (i.e., innovation), this paper shows that knowledge and innovation are both important drivers of economic growth, but have heterogeneous spatial impacts. In particular, the growth benefits accruing from knowledge seem rather selective and concentrated across space whereas the growth benefits generated by innovation seem more diffusive, and regions innovating in the absence of a strong local knowledge base can be as successful as more knowledge‐intensive regions in turning innovation into a higher growth rate, possibly by exploiting local informal knowledge and/or knowledge spillovers. These results are of great importance for the design of research and innovation policies within the frame of the Europe 2020 strategy.     

HOUSING CONSUMPTION DECLINES WITH INCOME IN THE OPEN‐CITY MODEL: THEORY AND EMPIRICAL EVIDENCE

This paper demonstrates that the standard urban model (SUM) has important, previously unknown, and rather counterintuitive predictions about the determinants of housing consumption in cities. For example, the SUM predicts that, as higher wages in the central business district prompt city growth, the housing space per household falls, that is, rising income is associated with falling housing consumption. Empirical testing using a specially constructed panel data set of U.S. cities, confirms this prediction. When city size, income, and housing price rise, housing space per household falls.     

A NOTE ON ADDED INFORMATION IN THE RAS PROCEDURE: REEXAMINATION OF SOME EVIDENCE

ABSTRACT.  An example in Miernyk (1977) presented a rather counterintuitive result, namely, that introducing accurate exogenous information into an RAS matrix estimating procedure could lead to an estimate that was worse than one generated by RAS using no exogenous information at all. This became an oft-cited black mark against RAS. Miller and Blair (1985) included a different (and small) illustration of the same possibility. It was recently pointed out by one of us that the Miller–Blair numerical results are wrong. For that reason, we decided to reexamine all the empirical evidence we could find on the subject. While figures in both Miernyk and Miller–Blair appear to be wrong, more recent published examples seem to have it right. In short, it is possible to identify examples in which additional (correct) information leads to poorer RAS estimates, at least under several fairly common metrics for comparing "closeness" of matrices. However, the overwhelming majority of the evidence is to the contrary. As a general rule, introduction of accurate exogenous information into RAS improves the resulting estimates, and counterexamples should probably not be taken too seriously.     

TIN AND PREHISTORIC MINING IN THE ERZGEBIRGE (ORE MOUNTAINS): SOME NEW EVIDENCE

Summary. A number of settlements and other traces of occupation have been identified in the mountainous areas near to tin and copper deposits in the Erzgebirge, and some of them excavated. The newly collected evidence seems to suggest that many small sources of metals, both tin and copper, were exploited, the former metal by washing from the river and creek beds. Though these sources were more modest than the British and Spanish tin supply, they seem to have served the Bohemian and Saxon Bronze Age cultures well.     

AN EARLY CELTIC POTTERY WORKSHOP IN NORTH WESTERN HUNGARY: SOME ARCHAEOLOGICAL AND TECHNOLOGICAL EVIDENCE

Summary. Excavations at the settlement site of Krautacker in the outskirts of Sopron (NW Hungary) have produced evidence of pottery manufacture from LT B to LT C. Three kilns of updraught type were discovered. Their technology is discussed. Stamp-decorated wheel-turned ware was produced throughout. The contexts and distribution of these vessels are considered.     

被动迁居后城市低收入原住民就业变动的成因及影响因素——以南京为例

城市绅士化引起的低收入原住民被动迁居及其行为响应一直受到学术界高度关注。以南京近1000名安置房社区居民就业变动调查数据为基础,系统分析了被动迁居后城市低收入原住民就业变动的成因及影响因素。研究结果表明:安置点与理想岗位空间错位是被动迁居后城市低收入原住民就业变动首因,个人或家庭以及单位等因素对就业变化亦产生重要作用;被动迁居后城市低收入原住民就业变动呈普遍性和差异性双重特征,城市绅士化运动在一定程度上可能导致弱势阶层内部发生分化。
