comparison shopping as a simultaneous move game this paper analyzes simultaneous move models of comparison shopping it shows that the equilibria in wilde schwartz 1979 can be rationalized as symmetric mixed strategies in an appropriately defined game in which information acquisition costs are endogenous it also shown that in the simultaneous move version of salop stiglitz 1977 nonexistence of equilibrium is not a problem in fact a variety of forms of equilibria emerge in that model pure strategy mixed strategy and blends of the two copyright 1992 by royal economic society

the intergenerational earnings and income mobility of canadian men evidence from longitudinal income tax data our objective is to obtain an accurate estimate of the degree of intergenerational income mobility in canada we use income tax information on about 400 000 father son pairs and find intergenerational earnings elasticities to be about 0 2 earnings mobility tends to be slightly greater than income mobility but nonparametric techniques uncover significant nonlinearities in both of these relationships intergenerational earnings mobility is greater at the lower end of the income distribution than at the upper end and displays an inverted v shape elsewhere intergenerational income mobility follows roughly the same pattern but is much lower at the very top of the income distribution

agency and brokerage of real assets in competitive equilibrium brokerage contracts for many categories of real assets are characterized by a common constant commission rate payable upon sale exclusive agency and contractual asking prices for a large market in steady state these conventional contracts produce in equilibrium no agency problem between a broker and his clients each broker spends the same time or effort selling each client s asset as the broker would spend on his own assets as in standard agency problems extra effort by a broker generates first order stochastically dominant distributions of bids by potential buyers unlike standard agency problems each broker can allocate his time or effort between selling the assets of his multiple clients and searching for new clients in competition with other brokers because brokers time spent searching for new sellers is dissipative entry by brokers is excessive in equilibrium article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

direct tests of the reservation wage property this paper provides the first direct experimental tests of the reservation wages predicted by finite horizon job search models previous indirect tests were based on search duration and search income the authors show that such indirect tests are weak by demonstrating that a naive rule performs essentially as well as the risk neutral model in predicting search duration in contrast direct tests of predicted reservation wages imply rejections of both the naive rule and the risk neutral model the general concave model survives direct tests with reservation wage data as does a specific logistic concave model copyright 1992 by royal economic society

experiments on unemployment benefit sanctions and job search behavior this paper presents the results of an experimental study on unemployment benefit sanctions the experimental set up allows us to distinguish between the effect of benefit sanctions once they are imposed the ex post effect and the threat of getting a benefit sanction imposed the ex ante effect we find that both effects matter moreover the ex ante effect turns out to be substantial and bigger than the ex post effect benefits sanctions stimulate the outflow from unemployment

reconsidering the use of nonlinearities in intergenerational earnings mobility as a test for credit constraints intergenerational earnings regression among canadian men is nonlinear middle earning families experience slower regression this pattern appears to confirm economic models of educational choice with credit constraints this paper reexamines the economic model and finds no connection between credit markets and earnings regression nonlinearities in particular credit constraints need not produce concavity and concavity does not imply credit market failure despite the invalidity of the test data availability will likely lead to continued research along this path the paper proposes an amended test using quantile regressions applied to canadian data the simple liquidity constraint conclusion is rejected

imperfect information monopolistic competition and public policy introduction ever since the pioneering work of george stigler 1961 and the provocative survey by michael rothschild 1973 economists have recognized that general equilibrium models yield competitive equilibria only by making strong assumptions about the information available to market participants in response to this difficulty theorists in recent years have developed a family of search equilibrium models that presuppose homogeneity and the absence of price discrimination and which also assume that information acquisition costs are positive for at least a subset of buyers on the basis of these and other assumptions the models attempt to show how price dispersion equilibria can arise solely as a result of the strategies that firms and consumers pursue one author summarized the results if information is costly each small firm obtains market power so that the relevant market structure with imperfect information is not per ect competition but rather monopolistic competition steven salop 1976 p 240

prices and qualities in markets with costly information this paper extends the seminal work of akerlof and salop and stiglitz in two directions i the sellers can select both the selling prices and quality levels of their good and ii the buyers can acquire price quality information about individual sellers at a cost we observe multiple price quality combinations in equilibrium which depend upon the distribution of information costs of consumers and upon whether quality or price or both are costly observable welfare comparisons of equilibrium are considered we show that welfare will be greater when price advertising is permitted

search at wholesale auto auctions wholesale trade in used cars is conducted by ascending bid auctions with sale subject to the seller s acceptance of the winning bid one out of three times the seller rejects the bid and no trade takes place i model the seller s decision as the outcome of search and thus determined by the winning bid distribution and a reported retail price this market is ideal for testing search theory since all offers whether or not accepted are observed qualitative predictions of the theory in particular the role of the variance are confirmed the quantitative results are more ambiguous

platform intermediation in a market for differentiated products we study a two sided market where a platform attracts firms selling differentiated products and buyers interested in those products in the subgame perfect equilibrium of the game the platform fully internalises the network externalities present in the market and firms and consumers all participate in the platform with probability one the monopolist intermediary extracts all the economic rents generated in the market except when firms and consumers can trade outside the platform in which case consumers obtain a rent that corresponds to the utility they would get if they did trade outside the platform the market allocation is constraint efficient in the sense that the monopoly platform does not introduce distortions over and above those arising from the market power of the differentiated product sellers an increase in the number of retailers increases the amount of variety in the platform but at the same time increases competition as a result the platform lowers the firm fees and raises the consumer charges in contrast an increase in the extent of product differentiation raises the value of the platform for the consumers but weakens competition in this case the platform raises both the charge to the consumers and the fee for the firms

trends in intergenerational income mobility previous studies of recent u s trends in intergenerational income mobility have produced widely varying results partly because of large sampling errors by making more efficient use of the available information in the panel study of income dynamics we generate more reliable estimates of the recent time series variation in intergenerational mobility our results which pertain to the cohorts born between 1952 and 1975 do not reveal major changes in intergenerational mobility

on intergenerational immobility evidence that adult credit health reflects the childhood environment we examine the persistence of inequality through credit health linking administrative records from several sources we document that childhood circumstances are strongly predictive of financial fragility in adulthood with credit scores among those from disadvantaged backgrounds nearly 100 points lower and 20 percentage points more likely to qualify as subprime we find evidence this relationship reflects differences in human capital and debt management still neither appears to fully explain the relationship our results reveal another dimension along which childhood circumstances persist into adulthood and could mean the many settings that evaluate individuals based on their credit health help reinforce inequities jel d12 e24 i32

the effect of attending the flagship state university on earnings a discontinuity based approach abstract this paper examines the effect of attending the flagship state university on the earnings of 28 to 33 year olds by combining confidential admissions records from a large state university with earnings data collected through the state s unemployment insurance program to distinguish the effect of attending the flagship state university from the effects of confounding factors correlated with the university s admission decision or the applicant s enrollment decision i exploit a large discontinuity in the probability of enrollment at the admission cutoff the results indicate that attending the most selective state university causes earnings to be approximately 20 higher for white men

intra day arbitrage opportunities in foreign exchange and eurocurrency markets we have two primary objectives in this study first we examine the frequency of attaining simultaneous equilibrium on spot and forward foreign exchange markets and on domestic and foreign securities markets second we measure the profitability of covered interest arbitrage and one way arbitrage our empirical analysis has been conducted using real time quotations the empirical results indicate that a the markets are efficient in the sense that profit opportunities from traditional covered interest arbitrage are rarely available and b the frequency of attaining simultaneous market equilibrium is surprisingly low thus opening the door for one way arbitrage the role of transaction costs in explaining the deviation of the actual forward price from the interest parity forward price has been studied extensively based on covered interest arbitrage frenkel and levich 1975 1977 have shown that the interest parity line is bound by a neutral band defined as

is the united states still a land of opportunity recent trends in intergenerational mobility abstract we present new evidence on trends in intergenerational mobility in the united states using administrative earnings records we find that percentile rank based measures of intergenerational mobility have remained extremely stable for the 1971 1993 birth cohorts for children born between 1971 and 1986 we measure intergenerational mobility based on the correlation between parent and child income percentile ranks for more recent cohorts we measure mobility as the correlation between a child s probability of attending college and her parents income rank we also calculate transition probabilities such as a child s chances of reaching the top quintile of the income distribution starting from the bottom quintile based on all of these measures we find that children entering the labor market today have the same chances of moving up in the income distribution relative to their parents as children born in the 1970s however because inequality has risen the consequences of the birth lottery t

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

chicken and egg competition among intermediation service providers we analyze a model of imperfect price competition between intermediation service providers we insist on features that are relevant for informational intermediation via the internet the presence of indirect network externalities the possibility of using the nonexclusive services of several intermediaries and the widespread practice of price discrimination based on users identity and on usage efficient market structures emerge in equilibrium as well as some specific form of inefficient structures intermediaries have incentives to propose non exclusive services as this moderates competition and allows them to exert market power we analyze in detail the pricing and business strategies followed by intermediation services providers copyright 2003 by the rand corporation

consumer search costs and market performance i introduction one of the seminal developments leading to the information economics revolution in the 1970s and 19c0s was diamond s 1971 theoretical result that in the absence of publicly posted price information the existence of even a small search cost could lead to monopoly pricing the intuition is straightforward no buyer with one price quote would want to search for a second unless it is likely that the buyer would encounter a price reduction that covers the search cost thus each seller has an incentive to price slightly above any common price and the noncooperative equilibrium in a single stage game yields a monopoly price this result is viewed as a paradox since a small search cost produces high prices but a zero search cost would produce the usual bertrand incentives that drive prices to competitive levels in the absence of capacity constraints and other imperfections 1 recent theoretical work has focused on finding a resolution to the paradox stahl 1989 for example generates a smooth transition between competitive and monopoly outcomes as the fraction of consumers with zero search costs increases from zero to one interestingly stahl finds that increasing the number of sellers makes pricing more monopolistic holding the number of informed buyers constant bagwell and ramey 1992 propose an alternative resolution that applies to an infinitely repeated market game where sellers who raise prices can develop a reputation that can affect sales in future periods bagwell and ramey show that buyers can obtain lower equilibrium prices by following a loyalty boycott search rule where low pricing sellers are rewarded with repeated purchases and high pricing sellers are punished with switching the price predictions vary continuously between monopoly and competitive levels depending on the size of the consumer search cost the policy relevance of the diamond paradox depends on whether there are realistic market environments in which small reductions in the availability of price information can cause large price increases 2 due to the difficulty of controlling and measuring information flows in natural markets the laboratory represents an ideal place to evaluate the diamond paradox and proposed resolutions the only experimental analysis of these issues is reported by grether schwartz and wilde 1988 who observed monopoly pricing in three of four predicted cases these results are suggestive but not definitive for reasons discussed below in particular as grether schwartz and wilde 1988 328 observe all four cases involved the same group of subjects to the extent possible this paper reports an experiment consisting of twelve market sessions designed to assess the effects of public price information the markets are conducted as normal posted offer markets except that buyers must pay a small cost each time they approach a different seller in baseline posted offer treatments all prices are publicly displayed to buyers while in search treatments prices are not publicly displayed in brief we find that prices approach competitive levels under the posted offer treatment and prices are significantly higher under the search treatment nevertheless the diamond prediction of monopoly pricing under search is not observed although increases in search costs do raise prices these results indicate that economists should take a more careful look at attempts to resolve the diamond paradox by introducing other factors that may impede monopoly pricing in markets with consumer search the paper is organized as follows our two primary treatments are outlined in section ii and results are presented in section iii the failure to observe the diamond monopoly price prediction motivated additional research on the effects of reputations and search costs which is presented in section iv the final section contains a conclusion ii

asymmetric information and intermediation chains we propose a parsimonious model of bilateral trade under asymmetric information to shed light on the prevalence of intermediation chains that stand between buyers and sellers in many decentralized markets our model features a classic problem in economics where an agent uses his market power to inefficiently screen a privately informed counterparty paradoxically involving moderately informed intermediaries also endowed with market power can improve trade efficiency long intermediation chains in which each trader s information set is similar to those of his direct counterparties limit traders incentives to post prices that reduce trade volume and jeopardize gains to trade

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

the employment effect of reforming a public employment agency by how much does an increase in operating effectiveness of a public employment agency pea and a reduction of unemployment benefits reduce unemployment using a recent labour market reform in germany as background we find that an enhanced effectiveness of the pea explains about 20 of the observed post reform unemployment decline the role of unemployment benefit reduction explains just about 5 of the observed decline due to disincentive effects resulting from the reform the reform of the pea could have had an even higher impact on unemployment reduction if there had been less focus on long term unemployed workers

fortunate sons new estimates of intergenerational mobility in the united states using social security earnings data previous studies relying on short term averages of fathers earnings have estimated the intergenerational elasticity ige in earnings to be approximately 0 4 due to persistent transitory fluctuations these estimates have been biased down by approximately 30 or more using administrative data containing the earnings histories of parents and children the ige is estimated to be around 0 6 this suggests that the united states is substantially less mobile than previous research indicated estimates of intergenerational mobility are significantly lower for families with little or no wealth offering empirical support for theoretical models that predict differences due to borrowing constraints

inducing risk neutral preferences with binary lotteries a reconsideration abstract we evaluate the binary lottery procedure for inducing risk neutral behavior we strip the experimental implementation down to bare bones taking care to avoid any potentially confounding assumptions about behavior having to be made in particular our evaluation does not rely on the assumed validity of any strategic equilibrium behavior or even the customary independence axiom we show that subjects sampled from our population are generally risk averse when lotteries are defined over monetary outcomes and that the binary lottery procedure does indeed induce a statistically significant shift toward risk neutrality this striking result generalizes to the case in which subjects make several lottery choices and one is selected for payment

buyers sellers and middlemen variations on search theoretic themes we study exchange that is bilateral but indirect it involves chains of intermediaries or middlemen in markets with frictions these frictions include search and bargaining problems we show how and how many intermediaries might get involved in a chain and how bargaining with one depends on upcoming negotiations with those downstream the roles of buyers sellers money and prices are discussed allowing us to clarify some neglected connections between different branches of search theory pursuing one such connection with monetary economics we show how bubbles can emerge in intermediation even with fully rational agents and perfect foresight

uncertainty and shopping behaviour an experimental analysis this paper reports experimental tests of three search equilibrium models these models which differ only in the search strategies available to the buyers have qualitatively different predictions that is equilibria price distributions single price equilibria at the competitive price and at the monopoly price and two price equilibria the experimental outcomes generally were consistent with the models predictions this suggests that debate on the utility of this class of models should shift to the realism of the models assumptions rather than focus on their ability to characterize market outcomes also since the basic models have been validated the project of analyzing experimentally the results of relaxing some of their assumptions seems worthwhile

can brokerage have an equilibrium selection role abstract this paper presents a model of housing markets with multiple search equilibria there are two problems associated with multiplicity of equilibria one is that the economy may end up at a pareto inferior equilibrium and the other is that it becomes more difficult to predict the effect of policy measures the objective of this study is to examine whether the brokerage institution can resolve these problems it is shown that brokerage can reduce the number of equilibria and can also improve welfare by moving the economy to a pareto superior equilibrium however under certain conditions brokerage reduces welfare and creates additional coordination problems by increasing the number of equilibria

the role of intermediaries in enhancing market efficiency in the ethiopian grain market this paper investigates the impact of the institution of brokerage on the optimal search behaviour and the welfare gains and losses of traders in the ethiopian grain market without brokers the privately optimal search diverges from the socially optimal search due to the positive spill over of individual search behaviour numerical analysis using the actual distribution of search costs and search efficiency obtained from primary data collected in ethiopia reveals that this externality is partially internalised by the presence of brokers and that total welfare increases significantly due to a more efficient allocation of search effort

what happens when information leaves a market evidence from postbankruptcy consumers federal law mandates the removal of personal bankruptcies from credit reports after 10 years the removal s effect is market efficiency in reverse the short term effect is a spurious boost in apparent creditworthiness especially for the more creditworthy bankrupts delivering a substantial increase in both credit scores and the number and aggregate limit of bank cards the longer term effect is lower scores and higher delinquency than initial full information scores predict these findings relate to both the debate over the bankruptcy code and the wisdom of influencing market clearing by removing information

delay in trade networks we study decentralized markets involving producers and consumers that are facilitated by middlemen we do this by analyzing a noncooperative networked bargaining game we assume a complete information setup wherein all the agents know the structure of the network the values of the consumers and the transaction costs involved but allow for some search friction when either producers or consumers trade with middlemen in such a setting we show that sunk cost problems and a heterogeneous network can give rise to delay or failure in negotiation and therefore reduce the total trade capacity of the network in the limiting regime of extremely patient agents we provide a sharp characterization of the trade pattern and the segmentation of these markets

the intergenerational transmission of risk and trust attitudes recent theories endogenize the attitude endowments of individuals assuming that they are shaped by the attitudes of parents and other role models this paper tests empirically for the relevance of three aspects of the attitude transmission process highlighted in this theoretical literature 1 transmission of attitudes from parents to children 2 an impact of prevailing attitudes in the local environment on child attitudes and 3 positive assortative mating of parents which enhances the ability of a parent to pass on his or her attitudes to the child we focus on two fundamentally important attitudes willingness to take risks and willingness to trust others we find empirical support for all three aspects providing an empirical underpinning for the literature an investigation of underlying mechanisms shows that socialization is important in the transmission process various parental characteristics and aspects of family structure are found to strengthen the socialization process with implications for modeling the socialization production function and for policies focused on affecting children s non cognitive skills the paper also provides evidence that the transmission of risk and trust attitudes affects a wide variety of child outcomes implying a potentially large total effect on children s economic situation

advance production in experimental markets the effects of advance production in posted offer and double auction markets are investigated previously observed differences between these institutions in mean contract prices and in the distribution of producers and consumers surpluses under the production to demand condition disappear when sellers make output decisions and incur production costs prior to the start of trading the double auction institution remains more efficient under advance production the results suggest that the differential effects of alternative trading institutions on market outcomes may be partially offset by the production conditions characterizing a market

one way arbitrage foreign exchange and securities markets a note theorem in the case of traders with exogenous needs to acquire foreign currency recently deardorff 3 coitned the phrase one way arbitrage to describe the behavior of those traders and showed that it probably precludes round trip covered interest arbitrage from breaking even deardorff s analysis focuses on the conditions under which in the presence of transaction costs there would be both spot and forward transactions on the foreign exchange markets at equilibrium in this paper we extend the analysis to derive the conditions under which transactions would exist in both the home and foreign securities markets and we generalize the results to the case of transactions in all markets

product quality and imperfect information this paper considers markets in which consumers are imperfectly informed about both product prices and quality levels offered by firms we characterize necessary and sufficient conditions for existence of the various equilibrium configurations of price and quality that can arise in two paradigm cases when all consumers prefer higher quality and when all consumers prefer lower quality our results suggest that firms will exploit imperfect information by charging noncompetitive prices as well as by offering other than ideal quality in the former case but only by changing noncompetitive prices in the latter case

how does your kindergarten classroom affect your earnings evidence from project star in project star 11 571 students in tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade this article evaluates the long term impacts of star by linking the experimental data to administrative records we first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27 college attendance home ownership and retirement savings we then document four sets of experimental impacts first students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes class size does not have a significant effect on earnings at age 27 but this effect is imprecisely estimated second students who had a more experienced teacher in kindergarten have higher earnings third an analysis of variance reveals significant classroom effects on earnings students who were randomly assigned to higher quality classrooms in grades k 3 as measured by classmates end of class test scores have higher earnings college attendance rates and other outcomes finally the effects of class quality fade out on test scores in later grades but gains in noncognitive measures persist

a model of covered interest arbitrage under market segmentation existing models of covered interest arbitrage typically assume market participants have equal capital and foreign exchange market access this paper derives sufficient conditions for the existence of neutral interest parity forward price bands when capital markets are segmented and exchange rates are dually quoted all forward price intervals are completely characterized in terms of simultaneous two way and one way arbitrage flow possibilities the parameters of the no arbitrage price region are shown to be established on the basis of relative advantage with respect to the set of available arbitrage strategies copyright 1991 by ohio state university press

heterogeneous borrowers liquidity and the search for credit abstract we develop a general equilibrium model of credit formation where borrowers and lenders must search for matches and where the composition of borrowers adjusts to satisfy equilibrium entry conditions when market liquidity dries up as a result of fundamental shocks to the system fewer borrowers will participate in the credit market with low quality borrowers suffering disproportionately because of a flight to quality however less liquid credit markets need not be associated with lower social output because the effect of higher average quality may outweigh that of reduced market participation depending crucially on the source of the liquidity shock

middlemen in bilateral search markets this article examines the role of middlemen in bilateral search markets e g employment agencies real estate brokers it is shown that the middleman narrows the set of buyer firm and seller worker types who search seller types with high valuations and buyer types with low valuations drop out of the search market and instead trade through the middleman the middleman also decreases the equilibrium search intensities of those agents who search it is proven that the middleman improves welfare if search is very costly and inefficient and decreases welfare if search is effectively costless and very efficient

economic search an experimental study this paper presents results of experiments designed to test several of the hypotheses present in the theoretical literature on optimal economic search first we test whether the subjects searchers actually search for wages in ways that are consistent with setting an optimal reservation wage we then proceed to determine experimentally the effects of risk aversion increased search costs changes in risk brought about by a mean preserving transformation of the distribution of wage offers the presence or absence of recall the existence of a finite horizon and the searcher s state of knowledge about the underlying distribution of wages in general we find that the searchers exhibit behavior that is consistent with that predicted by theory differences between risk neutral and risk averse searchers are found and the responses of both groups to changes in search costs in the degree of risk or in the state of knowledge are consistent with theoretical predictions

does the law of one price hold in international financial markets evidence from tick data abstract this paper investigates the validity of the law of one price lop in international financial markets by examining the frequency size and duration of inter market price differentials for borrowing and lending services one way arbitrage using a unique data set for three major capital and foreign exchange markets that covers a period of more than seven months at tick frequency we find that the lop holds on average but numerous economically significant violations of the lop arise the duration of these violations is high enough to make it worthwhile searching for one way arbitrage opportunities in order to minimize borrowing costs and or maximize earnings on given funds we also document that such opportunities decline with the pace of the market and increase with market volatility

labor market search an experimental study the theoretical results derived from models of economic search have implications which relate to the structure and performance of labor markets utilizing a series of laboratory experiments we attempt to capture many of the features of workers search and also the conditions under which labor markets operate by varying certain of the experimental conditions we are able to determine the searchers responses to changes in the terms of unemployment insurance to the existence of a minimum wage and to different states of information about the underlying distribution of wages in most cases the behavior of the searchers is consistent with that predicted by theory

risk attitudes and reservation wages of unemployed workers evidence from panel data abstract this paper studies risk attitudes of unemployed job seekers and their relationship to self reported reservation wages we find that risk aversion is prevalent and that reservation wages decrease slightly over time furthermore risk aversion and reservation wages are negatively correlated

auction and the informed seller problem a seller possessing private information about the quality of a good attempts to sell it through a second price auction with announced reserve price the choice of a reserve price transmits information to the buyers we characterize the equilibria with monotone beliefs of the resulting signalling game and show that they lead to a reduced probability of selling the good compared to the symmetric information situation we compare the unique separating equilibrium of this signalling game to the equilibrium of a screening game in which an uninformed monopoly broker chooses the trading mechanism we show that the ex ante expected probability of trade may be larger with a monopoly broker as well as the ex ante total expected surplus

credit card redlining abstract this paper evaluates the presence of racial disparities in the issuance of consumer credit using a database of credit histories i link location based information on race with individual credit files after controlling for place specific factors such as housing vacancy rates and general population demographics i find qualitatively large differences in the amount of credit offered to similarly qualified applicants living in black versus white areas high data quality allows distinguishing between issuer provision supply and utilization of credit demand additional estimates using information on payday lending provide support for idea that issuers condition lending on location

trading networks with price setting agents abstract in a wide range of markets individual buyers and sellers trade through intermediaries who determine prices via strategic considerations typically not all buyers and sellers have access to the same intermediaries and they trade at correspondingly different prices that reflect their relative amounts of power in the market we model this phenomenon using a game in which buyers sellers and traders engage in trade on a graph that represents the access each buyer and seller has to the traders we show that the resulting game always has a subgame perfect nash equilibrium and that all equilibria lead to an efficient allocation of goods finally we analyze trader profits in terms of the graph structure roughly a trader can command a positive profit if and only if it has an essential connection in the network thus providing a graph theoretic basis for quantifying the amount of competition among traders

search method use by unemployed youth this article presents a search model which shows that search method choices should be related to their costs and expected productivities as well as to nonwage income and wage offer distributions the empirical evidence then shows that the most frequently used search methods i e friends and relatives and direct applications without referral are also the most productive in generating offers and acceptances the number of methods used is affected by factors that presumably reflect opportunities as well as income sources and needs specific methods are chosen in a manner that generates positive average effects on outcomes for those using them

transactions costs and covered interest arbitrage theory and evidence the extent to which deviations from covered interest parity can be attributed to transactions costs has been exaggerated in the economic literature because the swap market in foreign exchange has been ignored it is shown that such deviations should be no greater than the lowest of the transactions costs in one of three markets the swap market or either of the two relevant securities markets this reconciles the theory with the data which show spreads of no more than a few basis points however the empirical results have no direct bearing on the conventional market efficiency hypothesis

endogenous outside options in coordination games experimental evidence abstract in this experiment traders choose between an outside option offered by an intermediary and playing a coordination game with each other the intermediary is either a broker or a dealer we find that intermediaries manage to attract traders even to offer levels lower than the payoff that traders could have obtained had they rejected the intermediary s offer for any given offer traders are more likely to accept a dealer s offer than a broker s offer the introduction of either intermediary type reduces average trader s earnings on the other hand intermediaries have a coordination role as predicted by the forward induction argument when traders reject the intermediary s offer and play the coordination sub game they achieve a significantly greater level of coordination

real time search in the laboratory and the market the standard model of labor market search posits repeated infinite horizon search from a fixed distribution of wages in a stationary environment under these circumstances the optimal search policy has a reservation wage property i e the decision to accept an offer involves a comparison of the offer with a time invariant constant w which itself is a function of the parameters characterizing the search environment a wage offer greater than or equal to w is accepted while any other is rejected and search is continued some early empirical job search studies however accumulated evidence of a declining trend in reservation wages over the course of an unemployment spell 1 since then several theoretical explanations for the declining reservation wage profiles have emerged all of which relax the stationarity assumption of the standard model for example reuben gronau 1971 assumes searchers have finite lives kenneth burdett 1977 gerard j van den berg 1990 james albrecht and susan vroman 2005 and others model short term unemployment benefits albrecht pieter a gautier and vroman 2006 permit directed search to heterogeneous prospects 2 john p danforth 1979 and silvio rendon 2006 consider general liquidity con strained search and burdett and tara vishwanath 1988 model learning about the job offer distribution behavioral explanations for declining reservation wages have been suggested by braunstein and schotter 1981 schotter and braunstein 1982 and others in this paper we present the results of the first ever to our knowledge real time search laboratory experiment performed in an effort to investigate this falling res ervation wage phenomenon where field studies of unemployed search often rely on strong identifying assumptions to recover searchers unobservable reservation wages in the laboratory we are able to elicit subjects complete reservation wage profiles in an incentive compatible manner 3 further in the laboratory we are able to

default risk cannot explain the muni puzzle evidence from municipal bonds that are secured by u s treasury obligations fama 1977 and miller 1977 predict that one minus the corporate tax rate will equate after tax yields from comparable taxable and tax exempt bonds empirical evidence shows that long term tax exempt yields are higher than theory predicts two popular explanations for this empirical puzzle are that relative to taxable bonds municipal bonds bear more default risk and include costly call options i study u s government secured municipal bond yields which are effectively default free and nonmalleable these municipal yields display the same tendency to be too high i conclude that differential default risk and call options do not explain the municipal bond puzzle article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

born with a silver spoon danish evidence on wealth inequality in childhood we study wealth inequality in childhood using danish wealth records from three decades while teenagers have some earnings we estimate that transfers account for at least 50 percent of wealth at age 18 and much more so for the rich children inheritance from grandparents does not appear quantitatively important but we do find evidence that children receive inter vivos transfers while wealth holdings are small in childhood they have strong predictive power for future wealth in adulthood asset holdings at age 18 are more informative than parental wealth in predicting wealth of children many years later when they are in their 40s hence childhood wealth reveals significant heterogeneity in the intergenerational transmission of wealth which is not simply captured by parental wealth alone we investigate why this is the case and rule out that childhood wealth in itself can accumulate enough to explain later wealth inequality our evidence indicates that childhood wealth is a proxy for a broad set of circumstances related to intergenerational transmission and future wealth accumulation including savings investment behavior and additional transfers

exclusive nightclubs and lonely hearts columns non monotone participation in optional intermediation in many decentralised markets the traders who benefi tm ost from an exchange do not employ intermediaries even though they could easily afford them at the same time employing intermediaries is not worthwhile for traders who benefit little from trade together these decisions amount to non monotone participation choices in intermediation only traders of middle type employ intermediaries while the rest the high and the low types prefer to search for a trading partner directly we provide a theoretical foundation for this hitherto unexplained phenomenon we build a dynamic matching model where a trader s equilibrium bargaining share is a convex increasing function of her type we also show that this is indeed a necessary condition for the existence of non monotone equilibria
