Decomposing the Dynamics of Regional Earnings Disparities in Israel
No full textThe literature on regional growth convergence and economic disparities has tended to confound four interwoven measurement phenomena. i) mean reversion (so-called beta convergence) where richer regions move towards the average from above and poorer regions from below. ii) diminishing inequality (so called sigma convergence) where the horizontal or spatial distribution of income becomes more equal. iii) mobility, where the rank of a region in the overall distribution of income changes either upwards or downwards. iv) leveling, where the richer regions become poorer (leveling-down) or the poorer regions become richer (leveling-up). We use a new statistical methodology, which treats these four phenomena on an integrated basis. The methodology is applied to Israeli regional earnings and house price data. We find that whereas earnings are strongly sigma divergent during the 1990s, this trend is offset when regional cost of living differences are taken into consideration. In this event, regional housing markets induce convergence in similar measure to the divergence induced by regional labor earnings.
The Making of a High Technology Node: Foreign-owned Companies in Israeli High Technology
No full textFELSENSTEIN D. (1997) The making of a high technology node: foreign-owned companies in Israeli high technology, Reg. Studies 31, 367-380. This paper conceptualizes the role of Israel's high technology sector as that of a node in a global production network. A node can be characterized by the intensity of the incoming and outgoing flow of information, investments and so on, that pass through it. Foreign investment is one indicator of the centrality of a node. Using case study and aggregate firm level evidence of US foreign investment in Israeli high technology, the paper tests the hypothesis that foreign involvement in the node economy is based on a rather different set of forces than those suggested by the foreign investment literature. The results seem to indicate the importance of node-type factors such as the centrality of small firms in R&D activity and labour force stability, rather than the standard determinants such as incentives, labour costs and infrastructure. The implications and policy issues relating to the development of a node economy are discussed. FELSENSTEIN D. (1997) L'etablissement d'un noeud de technologie avancee: les entreprises a capital etranger du secteur de la technologie avancee en Isra�l, Reg. Studies 31, 367-380. Cet article presente le role du secteur de la technologie avancee en Isra�l en tant que noeud au sein d'un reseau de production mondiale. Un noeud se caracterise par l'ampleur des entrees et des sorties d'information, d'investissement et ainsi de suite, qui le traversent. L'investissement etranger constitue un indicateur de la situation centrale du noeud. A partir des cas d'etudes et des preuves globales au niveau de l'entreprise en ce qui concerne l'investissement direct americain dans le secteur de la technologie avancee en Isra�l, cet article met a l'epreuve l'hypothese que la participation etrangere a l'economie de noeuds est fondee sur un ensemble de facteurs qui se distinguent de ceux que proposent la documentation qui traite de l'investissement etranger. Il semble que les resultats laissent voir l'importance des facteurs du type 'nodal' telle la situation centrale des petites entreprises dans la R et D et dans la stabilite de la main-d'oeuvre, plutot que les determinants de base tels les incitations, les couts de la main-d'oeuvre et l'infrastructure On discute des retombees et des questions de politique relatives au developpement d'une 'economie de noeuds'. FELSENSTEIN D. (1997) Die Schaffung eines Hochtechnologieknotenpunkts; in ausla�ndischem Besitz befindliche Gesellschaften in der Hochtechnologie Israels, Reg. Studies 31, 367-380. Dieser Aufsatz fasst die Rolle des Hochtechnologiesektors Israels als die eines Knotenpunkts in einem globalen Produktionsnetz auf. Ein Knotenpunkt kann durch die Intensita�t ihn durchlaufender eingehender und abgehender Stro�me von Information, Investierungen usw. charaakterisiert werden. Investierungen des Auslands sind Indikatoren der Zentralita�tsbedeutung eines Knotenpunkts. Mit Hilfe von Beweismateial von Fallstudien und einem U�berblick der u�berseeischen Investierungen der Vereinigten Staaten in der Hochtechnologie Israels untersucht dieser Aufsatz auf Firmenebene die Hypothese, dass ausla�ndische Verflechtung in der Knotenpunktwirtschaft auf einer Reihe von Gewalten beruht, die sich sehr von den in der Auslandsinvestierungsliteraur vorgeschlagenen unterscheidet. Die Ergebnisse scheinen weniger die Bedeutung der Standardbestimmungsfaktoren wie Anreize, Arbeitskosten und Infrastruktur als die 'Knotenpunkttypfaktoren' zu unterstreichen, wie die zentrale Stellung kleiner Firmen in Forschung und Entwicklung, und die Dauerhaftigkeit von Angestelltenverha�ltnissen. Es werden Implikationen sowie Fragen der Handlungsweisen im Hinblick auf die Entwicklung einer knotenpunktswirtschaft diskutiert.Node, Foreign-OWNED Companies, Israel, High Technology,
Regional Heterogeneity, Conditional Convergence and Regional Inequality
No full textBeenstock M. and Felsenstein D. Regional heterogeneity, conditional convergence and regional inequality, Regional Studies. The paper stresses the importance of accounting for regional heterogeneity in the dynamic analysis of regional economic disparities. Studies of regional growth mainly presume that regions are homogeneous in their socio-demographic composition. It is argued that the analysis of regional convergence needs to be tested conditionally, i.e. conditional upon the socio-demographic structure of the workers in the various regions. To this end, various measures of conditional regional earnings inequality are estimated using Israeli regional data for the period 1991-2002. The results show that about half of regional earnings inequality may be accounted for by the conditioning variables. Conditioning also makes a large difference to estimates of Gini and beta-convergence. Conditional beta and Gini mobility are about half their unconditional counterparts.

Cet article met l'accent sur l'importance de tenir compte de l'heterogeneite regionale dans l'analyse dynamique des ecarts regionaux economiques. En regle generale, les etudes sur la croissance regionale laissent supposer que la structure socio-demographique des regions est homogene. On cherche ici a affirmer que l'analyse de la convergence regionale doit etre tester sous condition, telle la structure socio-demographique des travailleurs dans les diverses regions. Dans ce but, on estime plusieurs mesures de l'ecart des salaires regionaux sous condition a partir des donnees israeliennes pour la periode de 1991 a 2002. Les resultats laissent voir que la moitie de l'ecart des salaires regionaux environ s'explique par les conditions posees. Poser des conditions influe sensiblement sur les estimations de convergence Gini et beta. Les mobilites beta et Gini sous condition se chiffrent a environ la moitie de leurs equivalents sans condition.

In diesem Beitrag wird die Bedeutung einer Berucksichtigung der regionalen Heterogenitat bei einer dynamischen Analyse der regionalen wirtschaftlichen Disparitaten betont. In den meisten Studien zum Regionalwachstum wird davon ausgegangen, dass Regionen hinsichtlich ihrer soziodemografischen Zusammensetzung homogen sind. Wir argumentieren, dass die Analyse der regionalen Konvergenz konditional uberpruft werden muss, d.h. in Abhangigkeit von der soziodemografischen Struktur der Arbeitnehmer in den verschiedenen Regionen. Zu diesem Zweck schatzen wir die verschiedenen Massstabe fur die konditionalen regionalen Einkommensunterschiede mit Hilfe von Regionaldaten aus Israel fur den Zeitraum von 1991 bis 2002. Aus unseren Ergebnissen geht hervor, dass sich etwa die Halfte der regionalen Einkommensunterschiede auf die konditionierenden Variablen zuruckfuhren lasst. Die Konditionierung macht auch bei den Schatzungen des Gini-Koeffizienten und der Beta-Konvergenz einen erheblichen Unterschied. Die konditionale Beta- und Gini-Mobilitat betragt etwa die Halfte ihrer nicht konditionalen Vergleichswerte.

En este ensayo recalcamos la importancia de tener en cuenta la heterogeneidad regional en el analisis dinamico de las desigualdades economicas a nivel regional. En los estudios de crecimiento regional se supone principalmente que las regiones son homogeneas en su composicion sociodemografica. Sostenemos que debe comprobarse condicionalmente el analisis de la convergencia regional, es decir, condicional en la estructura sociodemografica de los trabajadores en las diferentes regiones. Con este fin calculamos las diferentes medidas de las desigualdades salariales condicionales en las regiones usando datos regionales de Israel durante el periodo de 1991 a 2002. Nuestros resultados indican que aproximadamente la mitad de las desigualdades salariales regionales se deben a variables condicionales. Este acondicionamiento tambien muestra grandes diferencias en los calculos del indice Gini y la convergencia beta. La movilidad condicional de beta y Gini representan casi la mitad de su equivalentes incondicionales.

Homage to Felsenstein 1981, or why are there so few/many species?
No full textIf there are no constraints on the process of speciation, then the number of species might be expected to match the number of available niches and this number might be indefinitely large. One possible constraint is the opportunity for allopatric divergence. In 1981, Felsenstein used a simple and elegant model to ask if there might also be genetic constraints. He showed that progress towards speciation could be described by the build-up of linkage disequilibrium among divergently selected loci and between these loci and those contributing to other forms of reproductive isolation. Therefore, speciation is opposed by recombination, because it tends to break down linkage disequilibria. Felsenstein then introduced a crucial distinction between "two-allele" models, which are subject to this effect, and "one-allele" models, which are free from the recombination constraint. These fundamentally important insights have been the foundation for both empirical and theoretical studies of speciation ever since
Does "Trickle Down" Work? Economic Development and Job Chains in Local Labor Markets
No full textPersky, Felsenstein, and Carlson explore a new framework for evaluating state and local economic development efforts. They propose a method, referred to as the "job-chains approach," that they say clarifies the potential justifications for economic development subsidies as well as the limitations surrounding these efforts. This innovative approach addresses not only the number of job vacancies created as a result of a subsidized business investment or expansion, but also the extent to which gains are achieved by the unemployed and the underemployed, whether skilled or unskilled.job chains, labor mobility, business subsidies, tax incentives, low-wage workers

Critical Surveys Edited by Stephen Roper Understanding regional inequalities in small countries
No full textFelsenstein D. and Portnov B. A. (2005) Understanding regional inequalities in small countries, Regional Studies 39 , 647-658. This paper revisits the commonly held view that small countries do not exhibit significant regional disparities. The issue is framed as one in which the attributes of small size (land area, population and the magnitude of the economy) are mediated by a series of spatial and non-spatial factors such as distance, density, factor mobility, natural resources, land supply, social cohesion and governance structure. Given the existence of these mediators, the magnitude of regional disparities in small countries is not as surprising as it may seem at first glance.Small countries, Inequality, Regional disparities, Petits pays, Inegalite, Ecarts regionaux, Kleine, Lander, Unterschiede regionale, Ungleichheiten, Paises pequenos, Desigualdad, Disparidades regionales, JEL classifications: R11, R12, R15,
Introduction to the special issue: linking demand and supply in local labor market research
No full textFirst paragraph: Traditionally applied local labor market analysis, in both academic and policy circles, has focused primarily on either demand or supply factors, with often only a relatively token recognition of the other. This is surprising considering that the two are inexorably linked. For example, a policy proposal to increase high-skilled jobs in a given region requires a response of both the supply and demand sides of the labor market and of their complex interactions. In a regional context, this lack of attention is even more surprising. Cities and regions are particularly open systems and as such, local labor market imbalances within them on either the demand or supply sides can often be met by inter-regional mobility (migration) or intraregional mobility (e.g., commuting) as well as by occupational mobility
Job Vacancy Chains and Local Employment Creation; the Case of Supply-Side Restrictions
No full textThe job-chains model of local labor market change is a demand-driven analytic device for estimating the effects of new job creation. This paper explores the effects of restricting supply, i.e. limiting job access, on the model’s primary outcomes: vacancy chain multipliers, welfare effects and distributional impacts. Major sources of labor supply are the local unemployed, out of the labor force and in-migrants. Three simulations are reported relating to 1) restricting new jobs to current local residents (i.e. no in-migrants), 2) restricting new jobs to current residents in the first round of hiring only and 3) restricting hiring to local unemployed/out of labor force on the first round alone. The results are compared to the basic model that assumes no supply-side restrictions. In terms of chain length, welfare effects, distributional impacts and policy palatability, first round restrictions on in-migrants would seem to be the most plausible option. However, as an economic development strategy,well targeted demand-side initiatives would still seem to be preferable.
