multiple applications competing mechanisms and market power abstract we consider a labor market with search frictions in which workers make multiple applications and firms can post and commit to general mechanisms that may be conditioned both on the number of applications received and on the number of offers received by the firm s candidate when the contract space includes application fees there exists a continuum of symmetric equilibria of which only one is efficient and it has a posted wage equal to match output in the inefficient equilibria the wage is below match output and the value of a worker s application depends on whether he or she receives another offer this allows individual firms to free ride on one another and gives firms market power when we endogenize the number of applications and allow for general mechanisms only the efficient equilibrium survives by allowing for general mechanisms we are able to examine the sources of inefficiency in the multiple applications literature

competition and corporate performance are people right to think that competition improves corporate performance my investigations indicate first that there are some theoretical reasons for believing this hypothesis to be correct but they are not overwhelming furthermore the existing empirical evidence on this question is weak however the results reported here based on an analysis of around 670 u k companies do provide some support for this view most important i present evidence that competition as measured by increased numbers of competitors or by lower levels of rents is associated with a significantly higher rate of total factor productivity growth

time series analysis of market power evidence from g 7 manufacturing abstract this paper estimates the mark up of price over marginal cost in manufacturing for the seven major oecd countries applying hall s approach to market power measurement we have estimated the cyclical behaviour of the mark up a substantial degree of market power has been estimated in all countries examined and procyclical movements in the mark up competition seems to affect the level of mark up negatively

equilibrium unemployment dynamics the global dynamics of pissarides 1990 equilibrium model of aggregate unemployment are studied in the case of increasing returns to scale in production and constant returns to scale in the matching process an equilibrium is a dynamic path for the aggregate number of matches generated by best response search and recruiting investment decisions under rational expectations necessary and sufficient conditions for multiple equilibria including limit cycles are derived and illustrative examples are computed the application of saddle loop bifurcation theory is a novel feature of the analysis since one equilibrium pareto dominates all the others a macroeconomic coordination problem exists

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

lessons from the united states s antitrust history abstract the united states s antitrust policy spans more than 100 years for most of its history the united states has had the toughest antitrust laws and enforcement policies of any country in the world a shift to a more permissive attitude with regard to antitrust matters has occurred in recent years however this paper traces the changes in antitrust policy that have occurred and the concurrent shifts in thinking among economists on antitrust questions following this review the paper offers a critical appraisal of both the economic underpinning of the new learnings on antitrust matters and the changes in antitrust policy that have accompanied them it closes with a discussion of the implications of the analysis for european antitrust competition policy

illinois free banking experience recent studies by a j rolnick and w e weber 1983 1984 suggest that the conventional view of wildcat banking during the free banking era misrepresents the actual experience and that the problems of th e period were linked to a restriction imposed on the free bank rather than the lack of regulation illinois free banking experience is re examined to see if the traditional account of wildcat banking accurat ely portrays the actual experience and to test the validity of the ro lnick and weber assertions the illinois evidence shows that the trad itional accounts of wildcat banking were exaggerated and that the rol nick and weber assertions are substantiated copyright 1988 by ohio state university press

comparing the impact of credit constraints on the growth of smes in a transition country with an established market economy in this paper we compare the role of internal finance on the growth of firms between a leading transition country slovenia and an established market economy belgium we find that firms in slovenia are more sensitive to internal financing constraints than their belgian counterparts furthermore we find that de novo firms and firms with long term debt are most constrained and that micro and smes can face great difficulties in accessing external sources of finance foreign firms however are able to raise external finance and consequently their growth is less reliant on the availability of internal finance our findings appear to indicate that although slovenian firms are no longer recipients of soft budget constraints the financial environment is not yet fully functional

the effects of competition policy on development cross country evidence using four new indicators abstract over the last two decades many developing countries have introduced competition policies this paper introduces four new indicators on various aspects of competition laws and competition agencies to make competition policies comparable these indicators are used to estimate the effects of competition policies and all four contribute at least marginally to explaining differences in total factor productivity this is also true if developing countries are analysed separately in addition to the direct effects of competition policy on total factor productivity an indirect effect is identified countries scoring high with regard to competition policy suffer less from corruption

a model of competition between unemployed and employed job searchers an application to the unemployment outflow rate in britain this paper proposes a model to explain the allocation of new jobs to workers the central innovation is the analysis of the competition for jobs between employed and unemployed job searchers it is argued that the endogeneity of the fraction of the employed engaging in search is a crucial determinant of the unemployment outflow rate the model is applied to the unemployment outflow rate in britain the model fits the data well and encompasses its main rival copyright 1993 by royal economic society

industrial concentration and price cost margin of the indonesian food and beverages sector this article investigates trends in industrial concentration and its relationship with the price cost margin in 54 subsectors of the indonesian food and beverages sector in the period 1995 to 2006 this study uses firm level survey data provided by the indonesian bureau of central statistics bps classified at the five digit international standard industrial classification isic level the results show a significant increase in industrial concentration in 1995 to 1999 which coincided with the period of the economic crisis in indonesia after 1999 the industrial concentration exhibits a slightly decreasing long term trend furthermore the industrial concentration for all subsectors tends to converge to the same value in the long run additionally results show that higher industrial concentration yields a higher price cost margin finally the introduction of the competition law in 1999 has slightly lowered industrial concentration and the price cost margin

unemployment and market size without strong empirical support labour market matching models typically assume constant returns to scale in matching we construct a tractable equilibrium random matching model with a general matching technology introducing market size effects the job finding rate varies with unemployment stable steady states may occur in regions of increasing or decreasing returns and multiple equilibria are welfare ranked by market size while the standard model relies on high frequency shocks to the steady state to explain the co movement of unemployment and job finding locally decreasing returns in matching generate plausible adjustment dynamics and slower convergence lastly an extension of the hosios condition internalises search externalities

free bank failures risky bonds versus undiversified portfolios almost 30 of the 872 banks established under the free banking system 1837 62 are considered failures unable to reimburse noteholders for the full value of their bank notes upon closure lacking sufficient data economists have focused on one of two general failure explanations poor regulation design or undiversified bank portfolios i test both explanations within hazard functions using warren weber s annual balance sheet data for almost every antebellum bank my results suggest that free banking s bond secured note issue was the underlying problem but individual banks could have avoided failure by diversifying their assets with loans and controlling their circulation

directed search with multiple job applications we develop an equilibrium directed search model of the labor market where workers can simultaneously apply for multiple jobs the main result is that all equilibria exhibit wage dispersion despite the fact that workers and firms are homogeneous wage dispersion is driven by the simultaneity of application choice risk neutral workers apply for both safe and risky jobs the former yield a high probability of a job oer but for low pay and act as a fallback option the latter provide with higher potential payo but are harder to get furthermore the density of posted wages is decreasing consistent with stylized facts unlike most directed search models the equilibria are not constrained ecient

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

can imperfect competition explain the difference between primal and dual productivity measures estimates for u s manufacturing it is well known that under the assumptions of constant returns to scale perfect competition and the absence of factor hoarding primal and dual productivity measures should be highly correlated the apparent lack of correlation is usually attributed to fixed factors of production in this paper i propose an alternative explanation by relaxing the assumption of perfect competition by controlling for the presence of a markup component i demonstrate that both productivity measures are in fact highly correlated for u s manufacturing the analysis also provides an alternative method of estimating a markup of prices over marginal cost that avoids certain difficulties inherent in some existing methods of estimation

indeterminacy and increasing returns abstract we investigate properties of the one sector growth model with increasing returns under two organizational structures capable of reconciling the existence of aggregate increasing returns with competitive behavior by firms the first involves input externalities the second involves monopolistic competition we show for parameters in close accord with recent literature on real business cycles that the model displays an indeterminate steady state that can be exploited to generate a model of business fluctuations driven by self fulfilling beliefs in our first class of models growth is generated by exogenous increases in factor productivity in the second class the marginal product of capital is large enough for endogenous growth journal of economic literature classification numbers e00 e3 o40

job search search intensity and labor market transitions an empirical analysis this article proposes an empirical structural job search model with endogenously determined search intensity the model describes both the behaviour of unemployed job seekers and on the job search it draws on data on various indicators for the intensity of search to examine the effect of the intensity of search on labour market transitions the estimation results provide insight into the effectiveness of search the impact of the benefit level on the search intensity of unemployed job seekers is quantified the estimation results are used to gain insight into the discouraged worker effect

fishing in different pools job search strategies and job finding success in canada in the early 1980s this article examines the job search methods of jobless workers and emphasizes sample selectivity in choice of job search strategies especially use of public employment agencies longitudinal data from the labour force survey of canada for 1981 1983 and 1986 indicate that job search methods change with the business cycle and that many people find jobs without any reported search the determinants of job search success also vary substantially over the business cycle implying a substantial social return to public employment agencies at the 1983 trough of the recession but no noticeable benefits when aggregate unemployment is relatively low

estimation of price cost margins and union bargaining power for belgian manufacturing abstract this paper extends hall s 1988 hall r e 1988 the relationship between price and marginal cost in us industry journal of political economy 96 921 947 methodology to analyze imperfections in both the product and the labor market for firms in the belgian manufacturing industry over the period 1988 1995 we investigate the heterogeneity in price cost mark up and workers bargaining power parameters among 18 sectors within the manufacturing industry as well as the relationship between both parameters using a sample of more than 7000 firms our gmm results indicate that ignoring imperfection in the labor market leads to an underestimation of the price cost margin evaluated at perfect competition in the labor market these findings are confirmed in the sectoral analysis sectors with higher workers bargaining power typically show higher price cost margins

the dynamics of industrial mark ups in two small open economies does national competition policy matter abstract in this paper we investigate the impact of competition policy on the level and the dynamics of firm price cost margins in two european countries belgium and the netherlands we study three questions i did the changes in the competition law and policy that took place in belgium in 1993 have an effect on the level and the evolution of the price cost margins of firms ii are price mark ups in the netherlands where there was no strict competition policy until recently higher than in belgium iii is openness import competition sufficient to discipline firm behaviour we find that the introduction of a new competition policy in belgium did not have any effect on the price mark ups in belgium we also find that mark ups in the netherlands are higher than those in belgium finally we find that import competition does not lead to lower price cost margins we offer a number of explanations and implications

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

directed search on the job and the wage ladder we model a labor market where employed workers search on the job and firms direct workers search using wage offers and employment probabilities applicants observe all offers and face a trade off between wage and employment probability there is wage dispersion among workers even though all workers and jobs are homogeneous equilibrium wages form a ladder as workers optimally choose to climb the ladder one rung at a time this is because low wage applicants are relatively more sensitive to employment probability than to wage and thus forgo the opportunity to apply for a high wage with a lower chance of success

bank runs in the free banking period free banks in the united states issued private banknotes without discretionary restriction of entry previous research suggests explanations for noteholders relatively large losses and the substantial number of banks that closed the authors examine these hypotheses and the hypothesis that contagious runs were important the evidence provides no support for the importance of wildcat banking due to par versus market valuation of bond reserves episodic but not general support for the importance of declining bond prices and support for contagion effects and contemporaries knowledge of them with little or no impact on the number of banks that closed copyright 1994 by ohio state university press

the relation between price and marginal cost in u s industry an examination of data on output and labor input reveals that some u s industries have marginal cost well below price the conclusion rests on the finding that cyclical variations in labor input are small compared with variations in output in booms firms produce substantially more output and sell it for a price that exceeds the costs of the added inputs the paper documents the disparity between price and marginal cost where marginal cost is estimated from annual variations in cost it considers a variety of explanations of the findings that are consistent with competition but none is found to be completely plausible

shopping externalities and self fulfilling unemployment fluctuations we propose a novel theory of self fulfilling fluctuations in the labor market a firm employing an additional worker generates positive externalities on other firms because employed workers have more income to spend and have less time to shop for low prices than unemployed workers we quantify these shopping externalities and show that they are sufficiently strong to create s complementarities in the employment decisions of different firms and to generate multiple rational expectations equilibria equilibria differ with respect to agents rational expectations about future unemployment we show that negative shocks to agents expectations lead to fluctuations in vacancies unemployment labor productivity and the stock market that closely resemble those observed in the us during the great recession

the unemployment volatility puzzle is wage stickiness the answer i discuss the failure of the canonical search and matching model to match the cyclical volatility in the job finding rate i show that job creation in the model is influenced by wages in new matches i summarize microeconometric evidence and find that wages in new matches are volatile and consistent with the model s key predictions therefore explanations of the unemployment volatility puzzle have to preserve the cyclical volatility of wages i discuss a modification of the model based on fixed matching costs that can increase cyclical unemployment volatility and is consistent with wage flexibility in new matches

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

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

pricing and matching with frictions suppose that n buyers each want one unit and m sellers each have one or more units of a good sellers post prices and then buyers choose sellers in symmetric equilibrium similar sellers all post one price and buyers randomize hence more or fewer buyers may arrive than a seller can accommodate we call this frictions we solve for prices and the endogenous matching function for finite n and m and consider the limit as n and m grow the matching function displays decreasing returns but converges to constant returns we argue that the standard matching function in the literature is misspecified and discuss implications for the beveridge curve

the cyclicality of the separation and job finding rates in france abstract in this paper we shed light on the relative contribution of the separation and job finding rates to french unemployment at business cycle frequencies by using administrative data on registered unemployment and labor force surveys we first investigate the fluctuations in steady state unemployment and then in current unemployment in order to take into account the unemployment deviations from equilibrium both data sets lead to quite similar results both rates contributed to unemployment fluctuations during the nineties 50 50 split while in the last decade the job finding rate was more significant and explained around 65 of the french unemployment fluctuations in particular the last business cycle episode including the last recession exacerbated the role of the job finding rate we then show that the predominant role of the job finding rate in the last decade holds when the economy is hit by aggregate business cycle shocks moving unemployment and vacancies along the beveridge curve

suspension of payments bank failures and the nonbank public s losses abstract we present evidence on the effects of suspensions of payments from an episode that is close to a controlled experiment for examining those effects in 1861 about 44 of the banks in wisconsin closed 81 of the banks in illinois closed and noteholders suffered substantial losses the historical record suggests that an effective suspension of payments in wisconsin but not in illinois may explain the difference our statistical evidence indicates that the suspension of payments increased the probability of a bank remaining open by about 21 percentage points and decreased noteholders losses by about 14 cents per dollar

state banks and the national banking acts measuring the response to increased financial regulation 1860 1870 the national banking acts and their supporting legislation led to 263 state bank closures and 934 charter conversions between 1863 and 1870 this paper measures and analyzes these sudden changes using the period s first complete bank level census the data suggest that the national capital requirements prevented many existing banks from converting to a national charter whereas a tax on state bank notes was responsible for the large number of closures the legislation also prevented new national banks from replacing closed state banks and instead encouraged note and security brokers to open new banks in developing areas along the manufacturing belt

competitive pressure and economic integration an illustration for spain 1983 1996 abstract this paper estimates sectoral mark ups in the spanish economy during the period 1983 1996 the data consists of a large firm level data set that encompasses all sectors of economic activity apart from financial institutions the time period considered is well suited to assess the pro competitive effect of economic integration as spain s economy became fully integrated in the eu which was itself embarking on a massive liberalisation exercise i find that sectors most exposed to international competition witnessed a significant drop in margins while those more sheltered from competitive pressures did not finally comparing estimated mark ups to accounting margins indicates that the latter are a reasonable proxy for margins obtained econometrically

procyclical multifactor productivity tests of the current theories this paper conducts various tests of four hypotheses to account for procycical multifactor productivity the hypotheses include imperfect competition increasing returns to scale labor hoarding and thick market externalities the test results provide strong evidence for imperfect competition and increasing returns and weak evidence for labor hoarding and thick market externalities however the markup and returns to scale parameter estimates are much smaller than those noted in previous research this difference results from the use here of gross output and intermediate inputs as opposed to the use in previous research of value added and primary inputs

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

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

persistence and volatility of beveridge cycles this paper aims to explain the magnitude and cyclical behavior of the fluctuations in unemployment and vacancies adding demand externalities to an otherwise standard search and matching model reduces the need for exogenous shocks in explaining these fluctuations under plausible parameter values the equilibrium dynamics include a stable limit cycle that resembles the empirically observed counterclockwise cycles around the beveridge curve quantitatively these endogenous beveridge cycles can explain half of the volatility and almost all persistence of unemployment without any exogenous forces avoiding the amplification and propagation problems of the standard model
