regional migration in britain an analysis of gross flows using nhs central register data the authors extend the use of a hiring function model whereby job seekers are matched with vacancies to the analysis of regional migration in britain annual data from the national health service central register for 1975 1989 are used to show that unemployment and vacancy rates distance and an index of similarities across regions in industry based employment composition help determine migration flows across regions the hiring function approach offers a consistent way of modelling gross and net flows and helps explain both the high level of gross relative to net flows and the tendency for migration to fall in a recession even when unemployment differentials widen excerpt

budget constrained search abstract a consumer with diminishing marginal utility in consumption who can search for lower prices will balance the gains from spreading consumption evenly through time against the benefits of delaying consumption until lower prices are revealed optimal programs of consumption savings and price are characterized for a general formulation of this problem intertemporal substitutability is measured by relative risk aversion that relative risk aversion is small is sufficient for the intuitive solution as the best current price rises more search and less consumption is done the general model is adapted to special cases among other things this shows that linear utility and sequential search implies ex nte calculable reservation prices and consumption only when search stops however this characterization is a consequence of the restriction to linear utility outside of this context reservation prices and consumption may not be calculable ex ante

sequential search with a budget constraint abstract for a buyer who searches sequentially for the lowest price from a known distribution but subject to a budget constraint the optimal policy will no longer have the reservation price property

protection with static collusion the present paper argues that when static collusion takes place there is a new justification for a tariff this occurs in the context of a model in which consumers observe prices at a cost and the industry structure is a duopoly with a home and a foreign firm because costly search induces imperfect information about prices on the part of consumers the ability to rapidly revise posted prices on the part of the duopolists leads to the appropriation of a substantial amount of consumer surplus the static collusion takes place under any trade policy thus a home tariff that shifts a duopoly equilibrium to the advantage of the home firm will be demonstrated to entail in the case of a nonprohibitive tariff no consumption cost from protection because this tariff generates revenue for the home government and greater profits for the home firm it will be welfare improving to the home country the concept of profit shifting as a motive for commercial policy in imperfectly competitive markets was pioneered by brander and spencer 6 2 in a model where home and foreign duopolists are nash courot competitors a tariff can shift profits from the foreign to the home firm by inducing the foreign firm to play less aggressively in the present paper the tariff shifts profits within the collusive outcome by precluding more aggressive play by the foreign firm 3 furthermore davidson 8 has disclosed that the level of a tariff can affect the incentives to collude in a quantity setting supergame with nash cournot punishments in the present model the tariff affects the collusive outcome that can be supported it does not however affect the incentives to collude

did migration in the 1980s narrow the north south divide this paper integrates empirical analysis of the decision to migrate from a region with that of destination choice thus we are able to study how net migration and not just gross outflows are influenced by regional labour market circumstances the results suggest that relative regional wages rates but not relative unemployment and vacancy rates are effective in reallocating labour from regions experiencing adverse demand shocks we find little evidence that manual labour is migrating from those regions with relatively high manual unemployment but that migration plays a more conventional role in the regional adjustment process for non manual workers

discrete equilibrium price dispersion an explicit solution of an equilibrium model with price setting firms and searching customers makes possible a number of comparativestatics predictions about how cost differences among firms search costs of customers and taxes will affect the mean and variance of the distribution of market prices another implication of the model is that a firm s demand depends on the difference between its price and the average price in the market

price dispersion price flexibility and repeated purchasing this paper presents a search model in which consumers repeatedly purchase a commodity the repetition of purchases leads to the formation of implicit contracts with sellers which generate a kink in the demand curve facing each seller these kinks can generate equilibrium price dispersion under conditions where single purchase search models predict no price dispersion despite the kinks prices are at least partially flexible in that some and possibly all sellers change their prices in response to changes in production costs or demand dispersion de prix flexibilite des prix et achats repetes ce memoire presente un modele de recherche dans lequel les consommateurs font des achats repete s d un bien la repetition de l achat entraine la formation de contrats implicites avec les vendeurs ceci cree un pli dans la cedule de demande a laquelle chaque vendeur fait face ces plis peuvent engendrer une dispersion des prix d equilibre alors que le meme modele ne predirait aucune dispersion de prix en l absence d achats repet s malgre les plis les prix sont au moins partiellement flexibles puisque certains vendeurs tous peut re peuvent changer leurs prix en reponse a des changements dans les cofuts de production ou dans la demande

job queues discrimination and affirmative action james r fain if employers have different becker type discrimination coefficients for different demographic groups then the implementation of affirmative action may have a differential impact on those groups we estimate two vector autoregressive models of the us economy including the unemployment rates of four demographic groups we find that a job queue existed before the implementation of affirmative action and that affirmative action changed the ordering of the job queue in manner that had a negative impact on nonwhite males we find evidence that affirmative action may have increased the unemployment rate of nonwhite males by increasing their duration of unemployment jel j71 j78 j64 j68 i introduction the relative status of demographic groups in the labor force has been undergoing significant change since the early 1960s throughout this period white females and racial minorities have experienced changes not only relative to white males but also relative to one another one such change is exhibited in relative unemployment rates figure 1 shows differentials in the smoothed unemployment rates using a 12 x 2 centered moving average for white females nonwhite males and nonwhite females for the years 1959 83 one can easily see that the relative unemployment burdens have varied over time focusing first on the two lines that are positive over the entire range one may see that prior to the late 1960s the status of nonwhite individuals especially nonwhite males relative to white females was improving however beginning in the late 1960s this trend reversed the unemployment rate differential between nonwhite males and white females increased from a low of 1 03 in july 1969 to a high of 11 12 in march 1983 similarly after declining during the 1960s the unemployment rate differential between nonwhite females and white females increased from a low of 3 49 in october 1969 to a high of 9 16 in august 1983 these reversals in trend indicate the status of white females relative to both nonwhite males and nonwhite females began improving in the late 1960s figure 1 also shows the status of nonwhite females improved relative to that of nonwhite males during the same time period the unemployment rate differential between nonwhite males and nonwhite females increased from a low of 3 13 in february 1968 to a high of 2 38 in february 1983 these three unemployment rate differentials all declined in the 1960s a time of tremendous social change and strong economic growth but all of these trends reversed direction in the 20 month period from february 1968 to october 1969 after the trend reversal the status of white females improved relative to both nonwhite males and nonwhite females and the status of nonwhite females improved relative to that of nonwhite males to put it another way nonwhite males lost ground relative to both nonwhite females and white females our goal is to examine what role if any the implementation of affirmative action in 1968 had in reversing these trends other possible explanations of the above noted reversal in trends certainly exist but several factors point to affirmative action as a potential cause of these changes first the timing is correct the trends reversed in close proximity to the implementation of affirmative action second whatever caused these reversals affected all minority groups did so within a short 20 month time span and its impact was sustained over a number of years a new federal policy designed to change the way firms hire minorities should have exactly this type of effect finally as we will argue below imposing affirmative action on discriminating employers will not benefit all demographic groups equally discriminating employers will continue to discriminate though the pattern of discrimination may change many of the traditional explanations of changes in relative unemployment rates are unlikely candidates to explain these significant and sustained reversals of longstanding trends

search and consumer theory a consumer faces list prices for commodities but can buy one at a discount discounts vary randomly between sellers the number of quotations sought depends on list prices search costs and wealth this function is homogeneous of degree zero and provided some sufficient conditions are satisfied is increasing in wealth decreasing in search cost independent of the list price of the discounted commodity if indirect utility is multiplicatively separable increasing in the list price if the commodity is a necessity increasing in the list price of substitutes slutsky s equation is generalized to include search

sectoral transformation and labour market flows in this chapter we examine the dynamics of adjustment in the labour market and in particular the movement of workers between industries it is often assumed that the speed with which the labour market must adjust has increased due to globalisation and or technological change if this is the case then these forces may be responsible for greater instability in the workplace the displacement of growing numbers of especially unskilled workers from declining sectors longer periods of unemployment and wage losses

testing models of consumer search using data on web browsing and purchasing behavior using a large data set on web browsing and purchasing behavior we test to what extent consumers are searching in accordance to various classical search models we nd that the benchmark model of sequential search with a known distributions of prices can be rejected based on the recall patterns we observe in the data moreover we show that even if consumers are initially unaware of the price distribution and have to learn the price distribution observed search behavior for given consumers over time is more consistent with non sequential search than sequential search with learning our

staunching emigration from east germany age and the determinants of migration following the unification of germany in 1990 eastern wages and unemployment both rose rapidly i demonstrate that rising wages reduced eastern emigration greatly while rising unemployment had little effect this reflects the behavior of the young who are very sensitive to source region wages and relatively insensitive to source unemployment i show that most of the effect of source unemployment comes from the contemporaneous effect on those laid off who are more likely to be older i find that compared to stayers young emigrants are much more skilled older emigrants are slightly more skilled and commuters are not more skilled as measured by education and pre move wages my conclusions are based on a comparison of results from aggregate inter state migration data and individual data from the eastern sample of the german socio economic panel for 1990 2000 jel j61 p23

disjoint search for the prices of two goods consumed jointly the extensive literature on searching for price information deals almost exclusively with the search for the price of a single good casual empiricism shows that consumers buy more than one good and search for the price of more than one good before any single purchase more importantly not all of these goods are sold at the same store search theory should therefore consider the problem of multiple search in order to determine the robustness of conclusions based on a theory developed from the problem of search for the price of a single good this paper reveals a number of insights that emerge when decisions taken in other markets are made explicit consider the situation facing the builder and designer of a new house among other things the builder must decide on the amount of insulation and the method of heating before construction starts the decision depends on the prices offered hence the builder will search for an acceptable offer when prices are not known with certainty if a low price for heat is found then little insulation is needed because the cost of lost heat is relatively low when relatively little insulation is needed the potential savings from a lower price of insulation are also small therefore the builder may be willing to accept a relatively high price for insulation in the event of costly search and having already found a low price for heat more generally the price that would be accepted in one market depends on what has been found in the other market the influence of one market on another is not clear consider another example when a low price for heating is known the cost in terms of lost heat of windows may be low thus the builder can install more windows at a lower opportunity cost

the impact of equal opportunity policy on sex differentials in earnings and occupations women began to enter nontraditional occupations at an increasing rate at the same time federal equal opportunity policy was strengthened in 1972 equal employment opportunity eeo policy was strengthened and expanded and equal opportunity in education became federal policy for the first time these policies constitute a two pronged attack on sex discrimination because they address impediments to mobility on both the demand and supply sides of the labor market together they should increase women s access to nontraditional jobs and to the skills necessary to perform them during the 1970 s women made occupational gains that are concentrated disproportionately in the white collar occupations one explanation for this is that the impact of federal equal opportunity policy differs across schooling levels in section i i discuss federal equal opportunity policy section ii contains empirical evidence on the direct effects of eeo policy on sex differentials in earnings and occupational segregation by sex section iii presents estimates of changes in the effect of schooling on women s entry into nontraditional occupations during the 1970 s and attempts to determine what portion may be due to equal educational opportunity policy and to indirect effects of eeo policy

demand function estimation and the law of one price this paper shows that the method of estimating of demand functions may contain an erroneous implicit assumption when aggregated data are used this assumption revealed by the choice of regressors yields estimates of own price elasticity and other coefficients that are inconsistent it can also cause heteroscedasticity in the second stage of two stage least squares estimation where none would otherwise exist

productivity and the role of college in narrowing the male female wage differential in the usa in 1980 this study analyses the impact that productivity factors and the particular role of college have upon the inequality in male and female wages using the 1980 1 100 public use sample the findings herein suggest that whereas both black and white females and black males who entered the labour force in 1975 or later possess productivity characteristics that are superior to their elder counterparts the productivity characteristics of white males entering the labour force over this period are significantly inferior to those possessed by older white males also in sharp contrast to a voluminous literature that concludes that college widens the wage gap between the sexes this analysis shows that college played a paramount role among the productivity characteristics in narrowing the gender wage differential in 1980

asymmetries in housing and financial market institutions and emu despite convergence pressures differences in housing and financial market institutions across the 15 member states of the european union are still enormous this paper argues that they have profound effects on the responsiveness of output and inflation in the different countries to changes in short term interest rates as well as to asset market shocks of external origin the economic reasoning behind this claim is set out and the institutional differences are described the paper assesses the sometimes conflicting empirical evidence on this issue barriers to convergence and implications for labour market flexibility are discussed the uk ireland finland and sweden tend to cluster at one extreme of the relevant institutional characteristics the paper concludes with a set of proposals for institutional reforms which would significantly reduce the tensions within emu and the potential for instability in these economies entailed by emu membership

regional sorting of human capital the choice of location among young adults in sweden berck p tano s and westerlund o regional sorting of human capital the choice of location among young adults in sweden regional studies migration rates are highest among young adults especially students and their location choices affect the regional distribution of human capital growth and local public sector budgets using swedish register data on young adults the choice of whether to enrol in education and the choice of location are estimated jointly the results indicate a systematic selection into investment in further education based on school grades and associated preferences for locations with higher per capita tax bases for students the estimates indicate lower preferences for locations with higher shares of older people the importance of family networks for the choice of location is confirmed

price dispersion and inflation evidence from israel the paper considers the question whether observed price differentials reflect perceived differences in quality service agreements or location or whether information imperfections can explain this phenomenon it sets out theoretical arguments linking inflation to reductions in the information stock held by agents and thus to greater price dispersion the hypothesis is tested using monthly price data for 13 uniquely defined goods sold in israel between 1971 and 1984 price dispersion is shown to be positively related to the rate of market price inflation since inflation is an unlikely proxy for changes in perceived characteristics the findings support price dispersion theories based on optimally imperfect decision making

geographic labour mobility and the cost of housing evidence from italy in recent years internal migration in italy has declined markedly notwithstanding the widening of the north south gap in terms of unemployment rates and real income here the extent to which the housing market has contributed to the decline is examined preliminary to this analysis differentials in the cost of housing between the macro areas of the country are estimated using data on the market price of houses located in 96 provincial capitals econometric evidence is provided supporting the view that the north south housing price differential is a notable factor in explaining the falling pattern of mobility the positive impact on migration from the south to the north of a wider gap in the two areas in terms of income and employment prospects has been offset by the housing price differential which has steadily risen at least from the mid 1980s onwards yet a considerable share of the decrease in mobility remains unexplained possibly owing to the heterogeneity in the composition of migration flows

modeling the search for the least costly opportunity abstract with the continuing growth in the number of opportunities available at virtual stores over the internet there is also a growing demand for the services of computer programs capable of scanning a large number of stores in a very short time we assume that the cost associated with each scan is linear in the number of stores scanned and that the resulting list of price quotes is not always satisfactory to the customer in which case an additional scan is performed and so on in such a reality the customer wishing to minimize her expected cost must specify the requested sample size and a rule control limit to stop the search in the context of search theory the above search model can be categorized as fixed sample size sequential with infinite horizon according to this model the expected search cost is a function of two decision variables the sample size and the control limit we prove that for arbitrary sample size the expected search cost is either quasi convex or strictly decreasing in the control limit and that the optimal expected search cost is quasi convex in the sample size these properties allow an efficient calculation of the optimal policy we also develop analytic formulas to calculate the cost s variance allowing customers to choose a slightly higher expected cost if there is a considerable decrease in the variance finally we present detailed examples for price quotes that are distributed uniformly or exponentially

urban labour markets the causes and consequence of change the labour market plays a key role in mediating the relationship between economic competitiveness and social cohesion within nations cities and regions it transmits external shocks and internal restructuring of the economy to the employment prospects incomes and quality of life of individuals and communities key issues concern the pace and nature of economic change the ability of the labour market to adjust whether some groups bear a disproportionate burden and what policies can help to mitigate these effects the labour force should also be viewed as more than a passive recipient of economic change in the language of urban competitiveness labour can be regarded as an urban asset with an in uence on economic performance through its productivity creativity and availability the issues surrounding labour market adjustment exibility and employability go to the heart of many contemporary economic and social theories and policies this paper provides an overview of contemporary labour market developments in britain s cities it also updates research from over a decade ago to establish the long term trends incorporates a selective review of recent literature and discusses the implications for government policy this approach is felt to be justi ed on the grounds that there has been less synoptic research on urban labour markets in britain during the past decade than there was in the 1970s and 1980s research has tended to become more specialised and focused on particular features of the labour market such as the growth of non employment and social exclusion particular localities or city types such as global and polycentric cities or particular adjustment processes such as migration commuting or wage exibility meanwhile there is a growing body of literature asserting that there has been a turn around and recovery in the performance of cities but with limited supporting evidence coincidentally there have been important developments in labour market policy including increasing emphasis placed on supply side perspectives individual behaviour skills and choice while the differential demand for labour in different places has been downplayed the rst section analyses the long term changes in labour demand looking particularly at the scale and composition of employment trends in the 1980s and 1990s compared with earlier decades despite major restructuring of the british economy and

trends in earnings differentials by gender 1971 1981 this paper clarifies trends in relative earnings by sex over the decade 1971 1981 and decomposes these trends to determine which factors contributed to a decline and which to an increase our analyses are based upon data from the annual demographic files of the current population survey for 1972 and 1982 this study is unique in that it estimates earnings functions in each year which are corrected for selectivity bias it is found that such a correction markedly raises the progress of white women relative to men among blacks the impact of the selectivity bias correction was to substantially lower the relative earnings increase of women however the coefficients on the selectivity variable were not significant the findings suggest declining sex role specialization and discrimination as conventionally measured over the decade on the other hand contrary to expectations the total effect of variables reflecting the sex composition of the individuals occupation worked to widen the sex differential over the period the sex differential was also adversely affected by a decline in the relative return to education especially for whites authors modified

equilibrium price distributions equilibrium price distributions for a homogeneous product consistent with individual incentives are investigated they arise in informationally imperfect markets in which the only primitive datum is the distribution of search costs it is shown that single multi and continuous price distributions are all viable long run phenomena depending on the nature of search costs a method for computing equilibrium price distributions is also provided jevons law of one price has long been an accepted dictum in economic theory in a classroom presentation it still serves sometimes implicitly as a major premise in many micro models of market interaction much of the descriptive theory as well as welfare analysis hinges on this assumption yet one s day to day experience reveals that price differentials are a viable phenomenon and that looking for lower prices may very well be a rewarding activity the prospects of eventually hitting a bargain and the resulting price reduction would more than compensate for the cost incurred during the search process moreover the existence of price dispersions appear to be an empirically stable phenomenon snapshots of markets for relatively homogeneous products reveal substantial and recurring price differentials stigler 1961 and pratt wise and zeckhauser 1979 for example report some evidence supporting this claim an important article by stigler 1961 focused economists attention on the crucial role played by the informational structure of markets it gave rise to the study of the

spatial dynamics of the housing market an interurban perspective a major unproven hypothesis in housing economics is that regional ripple effects are caused by household migration between regions this paper examines household migration and price ripples at the level of local housing markets driven partly by the fact that such migration linkages are likely to be more pronounced between local rather than regional housing markets following a review of regional housing market studies several hypotheses linking the existence of lead lag relationships and cointegration with the scale of migratory linkages between local housing market areas lhmas are proposed using private housing transactions data for strathclyde a sub region of scotland the paper identifies two clusters of lhmas that differ in terms of their migratory linkages with glasgow the hypothesised leading housing market of the sub region tests for lead lag relationships and cointegration confirm the link between migration and house price changes

human capital graduate migration and innovation in british regions with the aid of a geographical information system our paper constructs a three stage least squares simultaneous equation model to investigate the interrelationships between the interregional flows of human capital and the innovation dynamism of a region in order to do this we model the interregional migration behaviour of high quality british university graduates from university into first employment and we relate these human capital flows to both the labour market characteristics and the knowledge characteristics of the employment regions this is done for all industries and separately for just high technology industries our results indicate that for england and wales there is a two way causality between the interregional human capital employment migration flows of recent university graduates and the innovation performance of regions however the results for great britain as a whole depend on whether london is included and scotland is excluded we find little or no support for the argument that the presence of local universities or small firms promotes regional innovation

semi nonparametric estimation of consumer search costs this paper studies the estimation of the distribution of non sequential search costs we show that the search cost distribution is identified by combining data from multiple markets with common search technology but varying consumer valuations firms costs and numbers of competitors to exploit such data optimally we provide a new method based on semi nonparametric estimation we apply our method to a dataset of online prices for memory chips and find that the search cost density is essentially bimodal such that a large fraction of consumers searches very little whereas a smaller fraction searches a relatively large number of stores copyright c 2012 john wiley sons ltd

testing for long run convergence across regional house prices in the uk a pairwise approach this article tests for stochastic convergence in uk regional house prices using the recently developed pairwise approach this approach allows for unit root tests to be conducted on all n n 1 2 possible pairs of house price differentials across n regions in the uk thus avoiding the need to choose a base region or alternative national figure as the benchmark using mix adjusted house price data from 1973 q4 to 2008 q4 the main finding is that there is no evidence of long run convergence among regional house prices or of an equilibrium relationship towards which uk regional house prices have a tendency to gravitate

an experimental examination of the economics of information this article presents an experimental test of propositions that come from stigler s classic economics of information theory it reviews previous empirical evidence for the propositions and discusses the mixed support provided for the theory it also discusses a major assumption of the theory and presents hypotheses that suggest that the propositions are not as universal as has been thought the results indicate that buyers with more certain beliefs about retailer price images search less and are less responsive to changes in the costs and benefits of search than buyers with less certain beliefs finally the article discusses the implications of the results for both economics and marketing

the perverse effects of wage and price controls in search markets abstract this paper examines the effects of price ceilings and minimum wages on the performance of markets in which agents must invest in costly search to become informed about prices or wages in this context it is found that the market equilibrium may respond to changes in policy instruments in strikingly counterintuitive ways in particular the imposition of price ceilings and minimum wages may respectively result in consumer price increases and wage decreases thus an important implication of our analysis is that when unions fight to increase wages by raising the minimum wage they may paradoxically actually be reducing the average wage of its members

the sensitivity of consumer search to wages abstract while intuition suggests that an increase in wages should increase the time cost of consumer search for low prices this note shows that under reasonable conditions the resulting increase in consumption actually increases search intensity

compensation of regional unemployment in housing markets why are regional unemployment differentials in europe so persistent if as the wage curve literature demonstrates there is no compensation in labour markets we hypothesize that workers in high unemployment regions are compensated in housing markets modelling regional unemployment differentials as a consequence of centralized wage bargaining we show that clearing of land markets may undo the incentive for workers to migrate to low unemployment regions in general equilibrium the compensating differentials hypothesis is tested on city level data for several countries controlling for variation in income and amenities housing is found to be about 3 percent less expensive on average in cities where unemployment is 10 percent up an analysis of housing demand survey data which takes account of housing heterogeneity yields a similar negative relationship the magnitude of the income effect generated by this compensating differential is consistent with a 0 10 wage curve elasticity these findings weaken the case for regional support programs

estimation of complete demand systems from household budget data the linear and quadratic expenditure systems in this paper we explore two issues in empirical demand analysis the estimation of complete systems of demand equations using household budget data section i and the incorporation of demographic characteristics into such systems section ii although there are numerous studies which use time series data to estimate complete demand systems and many which estimate engel curves from household budget data there are virtually none which combine budget data from different periods to estimate complete systems since each budget study corresponds to a single price situation one might conjecture that estimation of complete systems would not be possible unless budget studies were available from a large number of periods this is incorrect in section i we argue that interesting complete demand systems can be estimated from a small number of budget studies despite the limited price variability represented in such data to demonstrate this we use budget study data for two periods to estimate a pair of related demand systems the familiar linear expenditure system les and a quadratic expenditure system qes a generalization of les in which the demand equations are quadratic in total expenditure the inclusion of demographic variables in the analysis of household consumption patterns is desirable because there are likely to be systematic differences in the consumption behavior of households with different demographic characteristics but the effects of demographic characteristics have seldom been studied within the framework of complete demand systems in section ii we propose translating as a general method for incorporating demographic variables into complete systems of demand equations this method has not previously been discussed as a general technique for bringing demographic variables into demand systems although it has been employed in several studies to improve the estimates of the les and the qes presented in section i we reestimate these two systems using translating to incorporate family size
