adaptive versus rational expectations and the fisher effect substantial controversy remains over the causes of interest rate fluctuations this controversy frequently focuses on the role of expected inflation the theoretical determinats of the nominal rate are examined usig the is lm as model and it is shown that the augmented fisher equation is sensitive to the expectations generating mechanism the model assumes that the nominal rate ceteris paribuschanges one for one with expected inflation the total impact however may take any value from zero to one the empirical analysis sequentially estimates reduced form equations based on adaptive and rational expectations the results confirm prior findings that nominal rates do not adjust one for one with inflation the results also yield some insight on the applicability of the assumption of rational versus adaptive expectations

the low skill trap recently it has become popular to argue that certain workers have fallen into a trap in which they have poor skills few job opportunities and a low return on training while others have not this paper demonstrates how such a trap can occur within a simple matching model with rent sharing rent sharing diminishes the worker s incentive to acquire skills however since firms also benefit from training rent sharing likewise induces job creation the subsequent improved matching prospects may offset the initial disincentive to invest however for this mechanism to be effective firms and workers must coordinate their actions if they do not the trap occurs

the impact of unemployment insurance on job search evidence from google search data job search is a key choice variable in theories of labor markets but is difficult to measure directly we develop a job search activity index based on google search data the google job search index gjsi we validate the gjsi with both survey and web based measures of job search unlike those measures the gjsi is high frequency geographically precise and available in real time we demonstrate the gjsi s utility by using it to study the effects of unemployment insurance policy changes between 2008 and 2014 we find no evidence of an economically meaningful effect of these changes on aggregate search

choosy search and the mismatch of talents this article proposes a multi sector matching model where workers have symmetric sector specific skills and the search market is segmented by sector workers choose the range of markets they are willing to participate in i identify a composition externality workers do not take into account the impact of their choice on sector specific mean productivity among the pools of job seekers consequently workers prospect too many market segments and there is room for public policy even when the so called hosios condition holds

matching with phantoms searching for partners involves informational persistence that reduces future traders matching probability in this article traders who are no longer available but who left tracks on the market are called phantoms we examine a dynamic matching market in which phantoms are a by product of search activity no coordination frictions are assumed and non phantom traders may lose time trying to match with phantoms the resulting aggregate matching technology features increasing returns to scale in the short run but has constant returns to scale in the long run we embed a generalized version of this matching function in the canonical continuous time equilibrium search unemployment model long run constant returns to scale imply there is a unique steady state whereas short run increasing returns generate excess volatility in the short run and endogenous fluctuations based on self fulfilling prophecies

do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods dauth w hujer r and wolf k do regions benefit from active labour market policies a macroeconometric evaluation using spatial panel methods regional studies the effect of active labour market policies on all job seekers in a region is assessed using the variation in the participation in these programmes across regions over time the starting point is an augmented regional matching function which is extended by allowing for a heterogeneous search effectiveness parameter for current participants and job seekers who finished a measure recently a spatial dynamic panel data model is estimated by using a quasi ml estimation procedure it is found that job schemes in the non profit sector wage subsidies and advancement of apprenticeships significantly increase the regional number of matches

new microfoundations for the aggregate matching function empirical studies of the aggregate labor market matching function have favored a cobb douglas functional form for which there are no microfoundations in the existing literature i present a new model for the matching process based on a telephone line poisson queuing process which unlike other microeconomic approaches can be integrated directly into standard theoretical search models this implies a ces matching function approximately cobb douglas when search costs are approximately linear the model allows empirical estimates of matching function parameters to be interpreted in terms of the costs and benefits of search

reemployment probabilities and returns to matching the assumption of constant returns in the matching function embodied in most bilateral search models is crucial to ensure the uniqueness of the unemployment rate along a steady state growth path this article explores the empirical viability of this assumption by estimating individual reemployment probabilities on a sample of unemployment entrants i apply hazard models to survey data on both completed and uncompleted unemployment durations the hypothesis of constant returns to matching is not rejected on the basis of the evidence that the job finding hazard depends only on local labor market tightness and is independent of its size

non uniformity of job matching in a transition economy a nonparametric analysis for the czech republic this study explores the properties and development of the matching technology in the czech republic during the transition to a market economy nonparametric additive modelling allows us to assess flexible functional forms which comprise for instance ces and trans log specifications this enables us to evaluate the matching process locally for each combination of unemployment and vacancies rather than being restricted to global coefficients special interest is devoted to analysis and economic determinants of regional variation in the returns to scale of the matching function non linearities are found in the partial adjustment process of unemployment outflows and a negative coefficient on vacancies in some years moreover increasing returns to scale in job matching are found locally returns to scale are found to be negatively correlated to the share in employment in services and to outmigration positively correlated to the employment share in industry the unemployment rate and various measures of ac

competition over high income workers job growth and access to labour in atlanta access to a large labour pool labour pooling leads to local economic concentrations through agglomeration economies however these concentrations may be self limiting by reducing labour availability through competition over high skill workers this paper examines whether labour pooling and labour availability of workers with different incomes account for local job growth in the atlanta metropolitan area between 2000 and 2006 workers income is employed to account for the human capital of workers including education and skills it is found that the availability of high income workers is the only positive significant factor for job growth and the spatial size of the effect is larger than the traffic analysis zone neighbourhood scale in contrast no labour pooling indicators show a positive association with job growth the finding casts doubt on labour pooling effects at the intraregional level and suggests avenues for further research on local area agglomeration economies

measuring international capital mobility a review many barriers to the international movement of capital across national boundaries have been dismantled over the course of the last 20 years financial integration was greatly enhanced by the removal of capital controls on the part of the united states germany canada switzerland and the netherlands after 1973 the recycling of surpluses to developing countries through the euromarkets in the 1970 s the removal of capital controls in the united kingdom and japan beginning in 1979 financial integration among european community countries including france and italy in preparation for 1992 recent moves toward financial liberalization in smaller countries in the pacific and the steady process of technical and institutional innovation that has proceeded around the world some popular tests of international capital mobility however appear to show anomalous results martin feldstein and charles horioka upset conventional wisdom in 1980 when they concluded that changes in countries rates of national saving had very large effects on their rates of investment and interpreted this finding as evidence of low capital mobility the argument

search theoretic models of the labor market a survey we survey the literature on search theoretic models of the labor market we show how this approach addresses many issues including the following why do workers sometimes choose to remain unemployed what determines the lengths of employment and unemployment spells how can there simultaneously exist unemployed workers and unfilled vacancies what determines aggregate unemployment and vacancies how can homogeneous workers earn different wages what are the tradeoffs firms face from different wages how do wages and turnover interact what determines efficient turnover we discuss various modeling choices concerning wage determination and the meeting process including recent models of directed search

optimal use of labor market policies the role of job search assistance abstract this paper demonstrates how economic theory can be combined with state of the art empirics to make quantitative statements about optimal policy using a large administrative data set for west germany as well as nonparametric and semiparametric estimation techniques i parameterize the model proposed by pavoni and violante 2005 2007 for the optimal choice of different financial and activation measures for unemployed workers the parameterized model is used to study the role of job search assistance in optimal welfare to work programs and assess the optimality of the west german policy in the period 2000 to 2002

estimating the stock flow matching model using micro data we estimate the stock flow matching model using micro level data from a well defined labor market using a dataset of complete labor market histories for both sides of the market we estimate hazard functions for job seekers and vacancies we find that the stock of new vacancies has a significant positive impact on the job seeker hazard over and above that of the total stock of vacancies there is an even stronger robust result for vacancy hazards thus we find evidence in favor of stock flow matching even when controlling for unobserved search heterogeneity and stratifying into submarkets defined by location and occupation

the minimal conditions for a financial crisis a multiregional intertemporal cge model of the asian crisis abstract the globalization of world capitalism constrains the ability of the developmental state to pursue an independent industrialization and foreign trade strategy we use an intertemporal multiregion cge model to study the fundamental reasons for a financial crisis we find that we can create a realistic crisis in the asia region when capital markets are open and there is an unexpected rise in the risk premium of the asia region when capital markets are closed and the state retains all its policy instruments the asia region not only avoids a crisis but increases its rate of growth

the decision to move house and aggregate housing market dynamics using data on house sales and inventories this paper shows that housing market dynamics are driven mainly by listings and less so by transaction speed thus the decision to move house is key to understanding the housing market the paper builds a model where moving house is essentially an investment in match quality implying that moving depends on macroeconomic developments and housing market conditions the endogeneity of moving means there is a cleansing effect those at the bottom of the match quality distribution move first which generates overshooting in aggregate variables the model is applied to the 1995 2004 housingmarket boom

successful employer search an empirical analysis of vacancy duration using micro data this paper provides the first estimates of the determinants of the duration of employer search in the uk we model duration until a vacancy is either successfully filled or withdrawn from the market the econometric techniques deal with multiple vacancies and unobserved heterogeneity dependent risks using flexible and parametric baseline hazards the hazards to filling and withdrawing exhibit negative and positive duration dependence respectively implying that the conditional probability of successful employer search decreases with duration we also find that nonmanual vacancies are less likely to fill consistent with there being skill shortages in the sample period

unemployment and nonemployment heterogeneities in labor market states abstract the determination of how to distinguish between unemployment and nonparticipation is important and controversial the conventional approach employs a priori reasoning together with self reported current behavior this paper employs an evidence based classification of labor force status using information about the consequences of the behavior of the nonemployed we find that marginal attachment defined as desiring work although not searching is a distinct labor market state lying between those who do not desire work and the unemployed furthermore important heterogeneities exist within these nonemployment states two subsets of nonparticipants both engaged in waiting display behavior similar to the unemployed

is the division of labour limited by the extent of the market evidence from french cities abstract this paper provides supportive evidence to the notion that the division of labour is limited by the extent of the local market we first propose a theoretical model its main prediction is that scarce specialists occupations are over represented in large cities using census data for french cities we find strong empirical support for this prediction

money output and the expected real interest rate this paper tests the exclusion of lagged growth rates of money and output from regression equations with serially correlated disturbances for the expected real interest rate the authors empirical approach is an extension of the empirical strategies of eugene f fama 1975 and frederic s mishkin 1981 which invoke the orthogonality of the inflation forecast error to predetermined regressors under the maintained hypothesis of rational expectations they discuss the implications of their tests for simple real business cycle models copyright 1991 by mit press

sequential auctions with randomly arriving buyers we analyze a dynamic market in which buyers compete in a sequence of private value auctions for differentiated goods new buyers and new objects may arrive at random times since objects are imperfect substitutes buyers values are not persistent instead each buyer s private value for a new object is a new independent draw from the same in this paper we consider a model of dynamic markets in which buyers and sellers arrive randomly to the market and examine the equilibrium behavior of market participants in response to these arrivals in particular we investigate the role of current and anticipated future market conditions in determining endogenous outside options in this setting we characterize the influence of these outside options on equilibrium price determination and study the manner in which equilibrium payoffs and behavior are affected by both current conditions and future dynamics in our model buyers face an infinite sequence of auctions for heterogeneous but stochastically equivalent objects each buyer s private value for a new object is a new independent draw from a fixed distribution that arrive at random times moreover new buyers probabilistically arrive on the market in each period thus in any given auction buyers are presented with the outside option of participating in a future auction for an imperfectly substituted equivalent object but with a potentially different number of competitors we describe the unique symmetric markov equilibrium of this model by deriving a precise characterization of this option value

turnover externalities with marketplace trading this article considers equilibrium decentralized trade when there is a marketplace where buyers and sellers meet costlessly since buyers have idiosyncratic match payoffs for each seller s good some buyers rather than trade with the current stock of sellers wait for new sellers to enter the marketplace to obtain a good they like a turnover externality exists where all traders are better off with higher entry rates of new traders furthermore this turnover externality supports multiple pareto rankable equilibria this provides new insights into similar results obtained in the random matching literature

marketplaces and matching this paper models equilibrium trading patterns when marketplaces exist and goods are differentiated when first visiting the market a buyer samples a stock of goods if fortunate the buyer matches with and purchases one of these goods and then exits the market if an initial match does not exist the buyer can now only match with the flow of new goods for sale the previous stock has been sampled and rejected in a steady state the current stock of unmatched traders on one side of the market is trying to match with the flow of new traders on the other side it is shown that this market behaviour describes matching patterns between unemployed job seekers and vacancies in uk job centres

tax rate effects on interest rates abstract this paper investigates empirically the effects of personal and corporate taxes on taxable interest rates the results suggest that the effective tax rate of marginal investors in the treasury bill market is that of households as opposed to that of tax exempt institutions or corporations

financial crises and balance of payments crises a simple model of the southern cone experience abstract this paper starts from a simple model of the domestic banking sector and develops the potentially destabilizing macroeconomic consequences of its role in intermediating foreign capital inflows both financial and balance of payments crises may result reminiscent of the southern cone experience

good bye financial repression hello financial crash some unintended consequences of financial liberalization in latin america are analyzed in this paper intrinsic imperfectious in financial markets and the policy dilemmas they pose are reviewed first the stylized facts of southern cone experiments in financial liberization are then presented alternative ways of organlzing domestic capital markets under latin american conditions are discussed and an eclectic reform mongering program is proposed

costly search and recruiting a labor market model with costly search and recruiting is constructed it incorporates many features found in other models and provides new insights into the effects of externalities and transaction costs the model possesses a continuum of equilibria some of which may be pareto ranked with different rates of unemployment despite the multiplicity of equilibria comparative statics results are obtained copyright 1987 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

on the effects of ranking by unemployment duration abstract we propose a theory based on the firm s hiring behavior that rationalizes the observed significant decline of callback rates for an interview and exit rates from unemployment and the mild decline of reemployment wages over unemployment duration we build a directed search model with symmetric incomplete information on worker types and non sequential search by firms sorting due to firms testing of applicants in the past makes expected productivity fall with duration which induces firms to rank applicants by duration in equilibrium callback and exit rates both fall with unemployment duration in our numerical exercise using u s data we show that our model can replicate quite well the observed falling patterns with the firm s ranking decision accounting for a sizable part

optimal unemployment insurance with human capital depreciation and duration dependence this paper studies the effect of human capital depreciation and duration dependence on the design of an optimal unemployment insurance ui scheme our results partially confirm those obtained in most previous studies benefits should decrease with unemployment duration the optimal program also generates two main novel features which are not present in stationary models first if human capital depreciates rapidly enough during unemployment ui transfers are bounded below by a minimal assistance level that arises endogenously in the efficient program second we study the optimality of imposing a history contingent wage tax after reemployment our numerical simulations based on the spanish and us economies show that the wage tax should decrease with the length of worker s previous unemployment spell and become a wage subsidy for long term unemployed workers as a by product of our study we develop a systematic approach suitable for studying recursively a wide range of dynamic moral hazard problems and other models with similar characteristics

stock flow matching this paper develops and quantifies the implications of the stock flow matching model for unemployment job vacancies and worker flows workers and jobs are heterogeneous so most worker job pairs cannot profitably match leading to the coexistence of unemployed workers and job vacancies productivity shocks cause fluctuations in the number of active jobs which in turn cause fluctuations in labor market outcomes we derive exact expressions for employment and worker transition rates in a finite economy and analyze their limiting behavior in a large economy a calibrated version of the model is consistent with the co movement of labor market variables observed in u s data and can explain about one third of their volatility

the long side of the market and the short end of the stick bargaining power and price formation in buyers sellers and balanced markets the determinants of bargaining power and price formation in a dynamic exchange market where new traders enter randomly over time are studied when agents on the long side of the market possess the option to wait for the arrival of future partners the terms of trade in the spot market must honor the value of this option the equilibrium terms of trade are expressed in intuitive closed form equations that highlight the distinct influences of short run spot market conditions and long run market demographics i introduction few concepts in economics are as intuitive as the idea that traders on the long side of a market wind up holding the short end of the stick that is they receive little or none of the gains from trade consider for instance the classic setting in which b identical buyers each with unit demands for an indivisible homogeneous good face s identical sellers each with one unit of the good for sale it is well known that in a broad class of one shot trading games all of the surplus in this setting goes to the short side of the market in equilibrium that is if b s buyers bid the price up to their reservation value often it is only when b s that market institutions the rules of the game have any bearing on the equilibrium division of surplus this classic result is somewhat brittle because of the discontinuity in the terms of trade when moving from positive to negative levels of excess demand its logic is familiar however from bertrand competition and it is very compelling the option value to an agent frozen out of a trade in a one shot market game is his reservation payoff of zero any outcome that confers nonzero surplus to a long side agent cannot be sustained in equilibrium because all of the long side agents who would otherwise be frozen out possess a strict incentive to undercut

duration dependence and labor market conditions evidence from a field experiment this article studies the role of employer behavior in generating negative duration dependence the adverse effect of a longer unemployment spell by sending fictitious resumes to real job postings in 100 u s cities our results indicate that the likelihood of receiving a callback for an interview significantly decreases with the length of a worker s unemployment spell with the majority of this decline occurring during the first eight months we explore how this effect varies with local labor market conditions and find that duration de pendence is stronger when the local labor market is tighter this result is consistent with the prediction of a broad class of screening models in which employers use the unemployment spell length as a signal of unobserved productivity and recognize that this signal is less informative in weak labor markets jel code j64

returns to scale in a matching model of the labor market abstract this paper presents evidence on the degree of returns to scale in the labor market using a transcendental logarithmic model of the labor market matching technology the empirical results imply locally increasing returns to scale and are consistent with multiple equilibria thereby suggesting a potentially welfare enhancing role for macroeconomic policy intervention

the degree of fiscal illusion in interest rates some direct estimates this article demonstrates why the procedures used in previous studies do not permit inference about the relationship between interestrates and taxes we present a model that leads to direct estimates of the degree to which interest rates respond to changes in tax rates the empirical results imply that the adjustment of taxable interest rates has been large enough to render after tax yields impervious to tax rate changes further tax exempt yields are unaffected by changes in taxrates thus there is no evidence of fiscal illusion in interest rates this abstract was borrowed from another version of this item

cross section estimation of the matching function evidence from england and wales this paper analyses how the levels of unemployment and vacancies affect the rate at which unemployed workers find employment the worker firm matching function in particular we test the robustness of previous empirical work by checking whether we obtain the same estimated function using cross section data rather than aggregate time series data we find strong evidence of constant returns to scale similar to previous work we also find larger cities have higher wages this provides indirect support for increasing returns but where those returns are taken in the form of better quality matches

frictional unemployment on labor flow networks abstract we develop an alternative theory to the aggregate matching function in which workers search for jobs through a network of firms the labor flow network the lack of an edge between two companies indicates the impossibility of labor flows between them due to high frictions in equilibrium firms hiring behavior correlates through the network generating highly disaggregated local unemployment hence aggregation depends on the topology of the network in non trivial ways this theory provides new micro foundations for the beveridge curve wage dispersion and the employer size premium we apply our model to employer employee matched records and find that network topologies with pareto distributed connections cause disproportionately large changes on aggregate unemployment under high labor supply elasticity

rational expectations business cycles in search equilibrium we examine the rational expectations equilibrium paths of the model of search and barter in diamond s aggregate demand management in search equilibrium for some initial positions there are two equilibrium paths converging to different steady states with the high activity path pareto dominating the low activity path with some parameters there is also a continuum of equilibrium paths converging to another steady state moreover there can be cycles that are equilibrium paths even though the environment is stationary

stock flow matching and the performance of the labor market we estimate outflow equations for vacancies and unemployed workers in britain departing from the stock based analysis of matching in two ways first we deal with the temporal aggregation problem that arises when discrete time data are used to describe continuous time processes second we allow for a stock flow matching mechanism in which the stock of traders on one side of the market matches with the flow of traders on the other side our estimates are in line with the predictions of stock flow matching in terms of higher exit rates of flows and of matching combinations between labor market stocks and flows furthermore employer search effectiveness did not seem to decline between the 1960s and the 1990s nevertheless some deterioration in worker search effectiveness is detected however less severe than that implied by previous stock based work

empirical matching functions searchers vacancies and un biased elasticities this paper shows that conventional empirical estimates of matching functions are systematically biased because unobservable and endogenous search behaviour such as on the job search by workers or the use of different search channels by firms is neglected i propose an approach for recovering unbiased elasticities under different scenarios of competition for workers and jobs without the need for constructing proxies for unobserved stocks of searchers and vacancies using german administrative data i estimate the biases affecting conventional studies and derive bias corrected estimates of the matching elasticities under different scenarios

directed search with multi vacancy firms abstract i construct a directed search model in which firms decide whether to enter a market and how many positions to create within this framework the number of firms and the size of each firm are determined endogenously wages play an allocative role in the matching process and the frictions inherent in this process derive from the equilibrium behavior of workers and firms i characterize the unique equilibrium comparative statics generate testable implications for cross sectional variation in matching efficiency as well as the dynamic behavior of vacancies and unemployment moreover allowing for ex ante heterogeneity across firms the model can easily and naturally generate the observed relationship between firm size wages profitability and hiring

taxation and inflation a new explanation for capital flows abstract in a world of mobile capital the current system of taxation implies that the after tax cost of capital and return to saving in each country are negatively correlated with the rate of inflation thus a country s net foreign asset position ought to be negatively correlated with its long run inflation rate the magnitude of these effects is shown to be potentially large for oecd countries cross section and time series regressions confirm that inflation rates are good predictors of net foreign assets the existing distribution of net foreign assets may therefore largely reflect tax distortions

the establishment level behavior of vacancies and hiring this paper is the first to study vacancies hires and vacancy yields at the establishment level in the job openings and labor turnover survey a large sample of u s employers to interpret the data we develop a simple model that identifies the flow of new vacancies and the job filling rate for vacant positions the job filling rate moves counter to aggregate employment but rises steeply with employer growth rates in the cross section it falls with employer size rises with worker turnover rates and varies by a factor of four across major industry groups we also develop evidence that the employer level hiring technology exhibits constant returns and that at the employer level and that employers rely heavily on other instruments in addition to vacancies as they vary hires we also develop evidence that effective recruiting intensity per vacancy varies over time accounting for about 41 of movements in aggregate hires in the 2007 to 2009 period our evidence and analysis provide useful inputs for assessing developing and calibrating theoretical models of search matching and hiring in the labor market

hot and cold seasons in the housing market every year housing markets in the united kingdom and the united states experience systematic above trend increases in prices and transactions during the spring and summer hot season and below trend falls during the autumn and winter cold season house price seasonality poses a challenge to existing housing models we propose a search and matching model with thick market effects in thick markets the quality of matches increases rising buyers willingness to pay and sellers desire to transact a small deterministic driver of seasonality can be amplified and revealed as deterministic seasonality in transactions and prices quantitatively mimicking seasonal fluctuations in uk and us markets

labor search and matching in macroeconomics abstract the labor search and matching model plays a growing role in macroeconomic analysis this paper provides a critical selective survey of the literature four fundamental questions are explored how are unemployment job vacancies and employment determined as equilibrium phenomena what determines worker flows and transition rates from one labor market state to another how are wages determined what role do labor market dynamics play in explaining business cycles and growth the survey describes the basic model reviews its theoretical extensions and discusses its empirical applications in macroeconomics the model has been developed against the background of difficulties with the use of the neo classical frictionless model of the labor market in macroeconomics its success includes the modelling of labor market outcomes as equilibrium phenomena the reasonable fit of the data and when inserted into business cycle models improved performance of more general macroeconomic models at the same time there is evidence against the nash solution used for wage setting and an active debate as to the ability of the model to account for some of the cyclical facts

the impact of tariff liberalization between the united states and mexico an empirical analysis a computable general equilibrium cge model of the us is constructed in order to simulate the impact of tariff liberalization between the united state and mexico following the implementation of the north american free trade agreement nafta we find that although this agreement will have a minimal effect on the us economy as a whole certain sectors and regions may experience substantial gain and losses overall however the treaty should increase economic welfare and enhance economic growth

a dynamic equilibrium model of search production and exchange we study a general equilibrium model where agents search for production and trading opportunities that generalizes the existing literature by considering a large number of differentiated commodities and agents with idiosyncratic tastes thus agents must choose nontrivial exchange as well as production strategies we consider decreasing constant and increasing returns to scale in the matching technology and characterize the circumstances under which there exist multiple steady state equilibria or multiple dynamic equilibria for given initial conditions we also characterize the existence of dynamic equilibria that are limit cycles equilibria are not generally optimal and when multiple equilibria coexist they may be ranked we analyze comparative statics and find that certain intuitive results do not necessarily hold without restrictions on the stochastic structure

tests of three parity conditions distinguishing risk premia and systematic forecast errors abstract this study provides evidence that uncovered interest differentials between currencies cannot be attributed to either risk premia or systematic forecast errors alone the evidence is based on developing joint tests of three parity conditions uncovered interest parity purchasing power parity and real interest parity the study tests parameter restrictions based on knowing that risk premiums only affect nominal and real interest differentials but not inflation differentials while systematic errors in forecasting exchange rates only affect nominal interest differentials and inflation differentials but not real interest differentials the study finds a variety of cases where deviations from some or all of the parity conditions can be systematically related to variables currently known to investors and borrowers the most intriguing evidence is that for some currencies these deviations from parity are perfectly correlated as if they were driven by a common factor

strategic bargaining and competitive bidding in a dynamic market equilibrium this paper extends the bargaining and matching literature such as rubinstein 1985 and gale 1986 and 1987 by considering a new matching process we assume that a central information agency exists such as job centres and newspapers in the labour market or real estate agents in the housing market which puts potential traders into direct contact with each other with agent heterogeneity equilibrium trade is characterized by existing traders on the other side since existing traders have already sampled and rejected each other two procedures of trade coexist namely strategic bilateral bargaining and a competitive bidding process depending on the number of potential matches a new trader obtains we characterize the unique symmetric markov perfect equilibrium to this stochastic trading game

the beveridge curve a survey important progress has been made in economists understanding of the beveridge curve from its measurement to its expression in canonical labor market models yet enduring puzzles remain chief among these are the empirical role of vacancies in the recruitment process the amplitude comovement and persistence of cyclical unemployment vacancy dynamics and the sources of lateral shifts in the beveridge curve the synthesis of these themes identifies several priorities for ongoing research including the role of entry costs into vacancy creation in shaping beveridge dynamics the cyclicality of search intensity both off and on the job and its relation to participation and job to job transitions the theory and measurement of mismatch and the sources of hysteresis in unemployment flows

does extending unemployment benefits improve job quality contrary to standard search models predictions past studies have not found a positive effect of unemployment insurance ui on reemployment wages we estimate a positive ui wage effect exploiting
