restaurant prices and the minimum wage in this paper we examine the effect of the minimum wage on restaurant prices we contribute both to the study of economic impact of the minimum wage and to the study of microeconomic patterns of price stickiness for this purpose we use a unique data set of individual price quotes collected to calculate the consumer price index in france and we estimate a price rigidity model based on a flexible s s rule we find a positive and significant impact of the minimum wage on prices the effect of the minimum wage on prices is however very protracted a change in the minimum wage takes more than a year to fully pass through to retail prices

the bond old bond spread abstract i document the profits on a trade that is long the old 30 year treasury bond and short the new 30 year treasury bond and is rolled over every auction cycle from june 1995 to november 1999 despite the systematic convergence of the spread over the auction cycle the average profits are close to zero the difference in repo market financing rates between the two bonds is a significant cost of carry in this trade i show that variation in the bond old bond spread is driven by the treasury supply of 30 year bonds as well as aggregate factors affecting investors preference for liquid assets

a simultaneous non linear model for labour migration and commuting evers g h m and van der veen a 1985 a simultaneous non linear model for labour migration and commuting reg studies 19 217 229 the paper deals with the importance of interregional labour supply mobility as a component of changes in the regional supply of labour after an exploratory analysis of this mobility labour migration and commuting an explanatory framework is developed based on interrelationships between these two types of mobility an aggregated logit model is used to model the several choices involving workplace and residential location where feedbacks are allowed in the decision tree finally empirical results for some branches of the decision tree are presented

real rigidities and the non neutrality of money rigidities in real prices are not sufficient to create rigidities in nominal prices and real effects of nominal shocks and by themselves small frictions in nominal adjustment such as costs of changing prices create only small non neutralities but this paper shows that substantial nominal rigidity can arise from a combination of real rigidities and small nominal frictions the paper shows the connection between real and nominal rigidity given the presence of nominal frictions both in general and for two specific sources of real rigidity one arising from goods market imperfections and the other from labour market imperfections

recreation demand and residential location abstract we use the properties of competitive location equilibrium to study the demand for recreation and the choice of primary residence location location specific recreation and employment lead to pooling equilibria in which consumers reside according to their preference for recreation in general the stronger the taste for recreation the greater the attraction of living close to the recreation site and the lower the demand for other goods including housing we explore the effects of trip frequency trip length and recreation cost on the spatial distribution of consumers we also consider the effect of the wage rate on recreation and location demands

valuing urban lakeview amenities using implicit and contingent markets amenities influence individual location decisions and affect overall social well being this comparative study focuses on the potential complementarity of implicit and contingent market approaches

residential mobility with job location uncertainty abstract this paper investigates the relationship between job changes and residential mobility a job change may be prompted by reasons unrelated to factors associated with housing consumption however a job change may lead to an adjustment to housing consumption i e residential relocation previous studies find that job relocations are positively associated with residential mobility this paper departs from previous studies by looking at the effects of an uncertain future job location on residential mobility and mobility expectation it is conjectured that with the existence of costs of residential mobility a household head s likelihood for changing jobs in the future dampens the household s propensity to move but encourages the formation of mobility expectation these conjectures are examined empirically using data from the panel study of income dynamics and they are confirmed

the demand for residence site characteristics the analysis of residential site choice is the primary concern in urban economics research on this problem is deficient in that rigorous theoretical models concentrate almost exclusively on access to the central business district cbd in this decision process while empirical models have been specified in a manner that is inconsistent with standard demand theory although these models possess the power of simplicity they are unable to explain the non monotonic location patterns which characterize urban areas without resorting to ad hoc theorizing this article develops and tests a model which is consistent with demand theory and is also capable of explaining non monotonic location patterns the hedonic rent function is seen as an intermediate step in the analysis of location which allows one to construct the complete data matrix necessary for the estimation of a set of demand functions for location specific traits the analytical importance of the functional form of this hedonic function is briefly noted finally the empirical analysis notes the importance of children in determining residential preferences with special attention being directed to the endogeneity of children with respect to the process of residential choice the traditional location model is generally tested by regressing some transformation of the annual rental payments or alternatively property value r on access or lack of access to the city center acc a vector of other locational traits z income i and a race variable mc

measuring the effect of subsidized training programs on movements in and out of employment despite over two decades of u s experience in operating large scale subsidized training programs for low income and unemployed workers the effects of these programs are still highly controversial the controversy arises from the difficulty of specifying the model of participant outcomes in the absence of training that is necessary in any nonexperimental program evaluation in this paper we suggest that some of these difficulties may be overcome by focusing on a very simple measure of outcomes namely the probability of employment we present a variety of estimates of the effect of training on the probability of employment for the 1976 cohort of adult male participants in the comprehensive employment and training act ceta program our methods range from a simple comparison of pre and post training employment probabilities between trainees and nonparticipants to a fully specified first order markov model of employment probabilities with individual heterogeneity there is consistent evidence across methods that ceta participation increased the probability of employment in the three years after training by from 2 to 5 percentage points classroom training programs appear to have had significantly larger effects than on the job programs although the estimated effects of both kinds of programs are positive we also find that movements in and out of employment for trainees and nonparticipants are reasonably well described by a first order process conditional on individual heterogeneity in the context of this model ceta participation appears to have increased both the probability of moving into employment and the probability of continuing employment

convenient prices currency and nominal rigidity theory with evidence from newspaper prices abstract certain items prices are often set to simplify and expedite transactions by coinciding with available monetary units requiring few pieces of money or requiring little change in this sense these prices are more convenient than other proximate prices this paper models a firm that explicitly incorporates convenience into its pricing decisions where convenience is quantified by the number of currency units in a transaction and illustrates the theoretical behaviors that can arise newspaper cover price data empirically support the theory across a broader range of goods and services convenience appears to play a role in effecting above average nominal price rigidity

commuting patterns and firm decentralization since most employed individuals must travel between home and work on a daily basis work place commuting has provided the point of departure for the monocentric model of residential location alonso 1964 mills 1972 muth 1969 one of the major behavioral assumptions of the monocentric model is that consumers prefer less commuting to more all else equal hence the model predicts that workers will take advantage of any opportunity to reduce their commutes in the monocentric situation in which all employment is located at the central business district cbd no such opportunity arises however decentralized firm location enables workers to shorten their commutes as firms have left the cbd to move into the residential area the monocentric model thus predicts that if firms have decentralized workers should have very short commutes in longrun equilibrium however significant commuting persists in the face of large scale firm decentralization such commuting leads to the belief that frictions with respect to residential and job mobility exist which prevent workers from achieving the long run equilibrium solution predicted by the monocentric model in this paper i hypothesize that individuals with greater job and residential mobility will have shorter commutes given decentralized firm location residential and job mobility are further hypothesized to be functions of socio economic and employment characteristics the results show sex income race household responsibilities and job mobility to be important in determining commuting behavior the monocentric model is based on a separation of the house and work place theoretically this separation can be measured either in terms of commuting time or distance however most tests of the monocentric model have used commuting distance hamilton 1982 blackley and follain 1987 the time vs distance issue is explicitly addressed in this paper by using both measures in the estimations the results

compensating differentials in emerging labor and housing markets estimates of quality of life in russian cities abstract the purpose of this paper is to see if an equilibrium model of compensating differences for amenities can be applied to a major transition economy russia we analyze russian labor and housing markets using data from the russian longitudinal monitoring survey rlms augmented by city and regional specific characteristics from other sources our estimated wage and housing value equations suggest that workers are compensated for differences in climate environmental conditions ethnic conflicts crime rates and health conditions after controlling for worker characteristics occupation industry and economic conditions and various housing characteristics we find evidence that these compensating differentials exist even after controlling for the regional pay differences regional coefficients used by the russian government to compensate public sector workers for living in regions that are designated as less desirable quality of life as measured by a group of eleven amenities varies substantially the highest ranked cities tend to be in relatively warm areas and areas in the western european part of the country our quality of life index is positively correlated with net migration into a region suggesting workers are attracted to amenity rich locations overall we find that a model of compensating differentials with controls for disequilibrium yields useful information about compensation for location specific amenities and quality of life in this large transition economy

government debt management the long and the short of it standard optimal debt management dm models prescribe a dominant role for long bonds and advocate against issuing short bonds they require very large positions in order to complete markets and assume each period that governments repurchase all outstanding bonds and reissue r r new ones these features of dm are inconsistent with u s data we introduce incomplete markets via small transaction costs which serves to make optimal dm more closely resemble the data r r are negligible short bond issuance substantial and persistent and short and long bonds positively co vary intuitively long bonds help smooth taxes over states and short bonds over time solving incomplete market models with multiple assets is challenging so a further contribution of this article is introducing a novel computational method to find global solutions

a search based theory of the on the run phenomenon we propose a model in which assets with identical cash flows can trade at different prices infinitely lived agents can establish long positions in a search spot market or short positions by first borrowing an asset in a search repo market we show that short sellers can endogenously concentrate in one asset because of search externalities and the constraint that they must deliver the asset they borrowed that asset enjoys greater liquidity a higher lending fee specialness and trades at a premium consistent with no arbitrage we derive closed form solutions for small frictions and provide a calibration generating realistic on the run premia

when do firms adjust prices evidence from micro panel data abstract the price setting behavior of manufacturing firms is examined using a large panel of quarterly firm survey data from 1984 to 2007 which allows changes in firms prices to be linked to several firm specific variables the results show that state dependent pricing is clearly present in a low inflation environment and that variables measuring the current situation of the firm especially costs for intermediate products are important determinants of price adjustments compared to purely time dependent features the state dependent variables significantly add to the explanatory power of a price adjustment probability model macroeconomic factors are significant but contribute little in terms of the goodness of fit furthermore when taking into account sticky plan models by excluding possibly predetermined price changes the importance of state dependent factors becomes even greater

residential mobility and job changes under uncertainty abstract this paper empirically investigates households residential mobility and job change decisions under uncertainty we allow households degree of risk aversion to be a confounding factor in the joint decision of residential mobility and job changes using panel data to estimate a random effects multinomial probit model of households joint decision of residential and job mobility our empirical results show that risk aversion discourages a household from making any changes moreover when compared to single changes in either job or residential locations risk aversion is more discouraging for joint changes to more central residential locations and less discouraging for joint changes to more distant residential locations these effects are statistically significant albeit small in magnitude our empirical results demonstrate the uncertainty does play a role in households job and residential mobility decisions

did the federal reserve s mbs purchase program lower mortgage rates abstract on november 25 2008 the federal reserve announced it would purchase mortgage backed securities mbs this program affected mortgage rates through three channels 1 improved market functioning in both primary and secondary mortgage markets 2 clearer government backing for fannie mae and freddie mac and 3 anticipation of portfolio rebalancing effects we use empirical pricing models for mbs yields and for mortgage rates to measure relative importance of channels the first two were important during the height of the financial crisis but the effects of the third depended on market conditions overall the program put significant downward pressure on mortgage rates

lumpy price adjustments a microeconometric analysis based on a reduced form state dependent pricing model with random thresholds we specify and estimate a nonlinear panel data model with an unobserved factor representing the common cost or demand components of the unobserved optimal price using this model we are able to assess the relative importance of common and idiosyncratic shocks in explaining the frequency and magnitude of price changes in the case of a wide variety of consumer products in belgium and france we find that the mean level and variability of the random thresholds are key for explaining differences across products in the frequency of price changes we also find that the idiosyncratic shocks represent the most important driver of the magnitude of price changes supplementary materials for this article are available online

market manipulation price bubbles and a model of the u s treasury securities auction market this paper models the u s treasury securities auction market and demonstrates that mar ket manipulation can occur in a rational equilibrium it is a dynamic model with traders participating in a when issued market a treasury auction and a resale market manipu lations occur when dealers in the when issued market use their knowledge of the net order flow in order to corner the auction and squeeze the shorts from the when issued market this manipulation equilibrium generates bubbles in treasury security prices and specials in repo rates we also compare discriminatory and uniform price auction rules with respect to manipulation our analysis shows that manipulations can occur in long run equilibrium under discriminatory price auctions but not under uniform price auctions

special repo rates this article provides the causes and symptoms of special repo rates in a competitive market for repurchase agreements a repo rate is in effect an interest rate on loans collateralized by a specific instrument a special is a repo rate significantly below prevailing market riskless interest rates this article shows that specials can occur when those owning the collateral are inhibited whether from legal or institutional requirements or from frictional costs from supplying collateral into repurchase agreements specialness increases the equilibrium price for the underlying instrument by the present value of savings in borrowing costs associated with the repo specials this article characterizes competitive repurchase or repo markets and the equilibrium relationship between repo rates and the underlying cash market prices repurchase markets are often called financing markets since they are effectively vehicles for collateralized borrowing that are often used to finance the purchase of the underlying collateral this article provides causes and effects of specials meaning specific repo rates significantly below prevailing market interest rates for loans of similar maturity and credit risk the example of united states treasury instruments is emphasized because of the extensive use of the treasury repo market as a means of hedging against or speculating on changes in u s interest rates and because of the high incidence of specials in treasury repo rates numerous specific instru

collusion in uniform price auctions experimental evidence and implications for treasury auctions in uniform price auctions of shares there exist collusive equilibria in which bidders capture the entire surplus from the auction as well as competitive equilibria in which the auctioneer captures the entire surplus from the auction we provide experimental evidence that in uniform price auctions non binding pre play communication facilitates convergence to collusive equilibrium outcomes on the other hand regardless of the opportunities for communication in discriminatory auction experiments subject strategies conform closely with the unique equilibrium in undominated strategies in which bidders gains are equal to the smallest tick size in the bidding schedule this evidence suggests that uniform price auctions of treasury securities may result in lower revenues than the currently employed discriminatory procedure

the interdependence of geographical migration with job and housing mobility in london congdon p 1988 the interdependence of geographic migration with job and housing mobility in london reg studies 22 81 93 a multinomial logit model is developed to analyse the association between residential migration within and from london with employment and tenure mobility migration is shown to interact more strongly with tenure change than career shifts and with changes of workplace as against changes in occupation in general the selectivity of migration in terms of age and income partly reflects such interactions implying biased estimates of selectivity in single equation migration models while occupational mobility and job linked migration are higher among lower income workers they are positively related to educational resources confirming human capital models of job search however gender and ethnic differentials in occupational and tenurial migration suggest segmentation of housing and labour markets congdon p 1988 l interdependance de la migration spatiale et de la mobilite par r

sticky prices as coordination failure this paper links the coordination failure and menu cost approaches to the microeconomic foundations of keynesian macroeconomics if a firm s desired price is increasing in others prices then the gain from price adjustment after a nominal shock is greater if others adjust this strategic complementarity leads to multiple equilibria in the degree of rigidity welfare may be much higher in the equilibria with less rigidity thus nominal rigidity arises from a failure to coordinate price changes jel e12 e30 keynesian macroeconomics waned in the 1970 s because economists grew disenchanted with its weak microeconomic foundations the central difficulty was that keynesian models were based on ad hoc rigidities in nominal wages and prices the 1980 s produced two approaches to reviving keynesian theory the menu cost literature n gregory mankiw 1985 george akerlof and janet yellen 1985 seeks to provide rigorous explanations for nominal rigidities these papers argue that small frictions in price setting are enough to produce large nominal rigidities in contrast the coordination failure literature russell cooper and andrew john 1988 abandons nominal rigidities and seeks alternative foundations for keynesian models the central idea is that many economic activities such as production e g john bryant 1983 trade e g peter diamond 1982 and investment e g nobuhiro kiyotaki 1988 exhibit synergism or strategic complementarity one agent s optimal level of activity depends positively on others activity strategic complementarity can lead to multiple equilibria with high activity equilibria superior to low activity equilibria thus an economy may be stuck in an underemployment equilibrium even though a superior equilibrium exists models with nominal rigidities and models with coordination failures are often presented as competing paradigms 1 this paper shows that this view is incorrect we take a step toward unifying the foundations of keynesian economics by showing that the two sets of ideas are highly complementary nominal rigidity arises from a failure to coordinate price changes this failure has the essential features of coordination failures in previous models flexibility in one firm s price increases the incentives for other firms to make their prices flexible this strategic complementarity leads to multiple equilibria in the degree of nominal rigidity equilibria with less rigidity more active price adjustment are often pareto superior to equilibria with more rigidity these results contribute to our understanding both of coordination failure and of nominal rigidity the range of keynesian phenomena explained by coordination failures is greatly expanded previous coordination failure models contain only real variables and thus ascribe no role to monetary policy or other determinants of nominal spending our results suggest that coordination failure is at the root of inefficient nonneutralities of money theories of nominal rigidities gain new empirical and policy im

how auctions work for wine and art interview auctioneers and even to buy a little wine in the meantime i have also had the opportunity with john abowd 1988 to observe and collect data on the auction sale of impressionist and contemporary paintings this paper reports on some of the empirical regularities that i and others have observed in the actual operation of the auction markets for these items in view of the rich and diverse array of theoretical literature on auctions it seems high time economists began to spell out precisely what facts it is meant to explain 2

heterogeneity in consumer price stickiness we examine heterogeneity in price stickiness using a large original set of individual price data collected at the retail level for the computation of the french consumer price index for that purpose we estimate at a very high level of disaggregation a piecewise constant hazard model as well as competing risks duration models that distinguish between price increases price decreases and product replacements the main findings are the following a at the product outlet type level the baseline hazard function of a price spell is nondecreasing b cross product and cross outlet type heterogeneity is pervasive both in the shape and the level of the hazard function as well as in the impact of covariates c there is strong evidence of state dependence especially for price increases d there is an asymmetry because determinants of price increases differ from those of price decreases

a sequential study of migration and job search this paper designs a multiarmed bandit mab sequential model for the analysis of the migration job search process the implications either are compatible with well known migration behavior or when novel are also plausible for example regions with large wage variability attract migrants and regions with large nonpecuniary returns increase both in migration and out migration a major advantage of this approach is the relative ease with which martingale estimators can be derived from the martingale structure of the model these martingale methods are exemplified for the return migration phenomenon

government intervention and strategic trading in the u s treasury market we study the impact of permanent open market operations pomos by the federal reserve on u s treasury market liquidity using a parsimonious model of speculative trading we conjecture that i this form of government intervention improves market liquidity contrary to conclusions drawn by existing literature and ii the extent of this improvement depends on the market s information environment evidence from a novel sample of federal reserve pomos during the 2000s indicates that bid ask spreads of on the run treasury securities decline when pomos are executed by an amount increasing in proxies for information heterogeneity among speculators fundamental volatility and pomo policy uncertainty consistent with our model

new estimates of climate demand evidence from location choice abstract we develop and apply to census data a new method for estimating climate demand the method is useful for ranking quality of life based upon a willingness to pay criterion our two major findings are that the willingness to pay quality of life index is correlated with the hedonic approach s ranking but that the migration approach generates much larger estimates of willingness to pay for a more moderate climate this finding is relevant for evaluating the economic impact of global warming

hedging winner s curse with multiple bids evidence from the portuguese treasury bill auction auctions of government securities typically permit bidders to enter multiple price quantity bids despite the widespread adoption of this institutional feature and its use by bidders the motivations behind its use and its effects on auction outcomes are not well understood theoretically and have been little explored empirically this paper proposes that bidders use multiple bids to adjust for winner s curse by spreading her bids a bidder aligns her outcome more closely to the aggregate outcome of the auction this hypothesis is tested using bidding data from treasury bill auctions in portugal i find that ceteris paribus a bidder submits a greater number of bids and disperses prices on these bids more widely when there is a greater potential for winner s curse in particular both these measures of bid spreading increase with the volatility of market interest rates and the expected number of participating well informed bidders

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

mechanism choice and strategic bidding in divisible good auctions an empirical analysis of the turkish treasury auction market we propose an estimation method to bound bidders marginal valuations in discriminatory auctions using individual bid level data and apply the method to data from the turkish treasury auction market using estimated bounds on marginal values we compute an upper bound on the inefficiency of realized allocations as well as bounds on how much additional revenue could have been realized in a counterfactual uniform price or vickrey auction we conclude that switching from a discriminatory auction to a uniform price or vickrey auction would not significantly increase revenue moreover such a switch would increase bidder expected surplus by at most 0 02 percent

intra urban mobility migration and tenure choice this analysis develops a model in which for the first time households mobility decisions are separated into intra urban movements and migrations these two mobility decisions and the households tenure own rent choice are estimated as part of a multinomial logit framework and are found to be jointly determined the literature suggests that the intra urban mobility and migration decisions are motivated by quite different factors consequently by separating the two choices for the purpose of estimation each equation can be specified more correctly in addition variables which affect migration can be shown to have an impact on intra urban mobility and tenure choice which would otherwise be ignored copyright 1991 by mit press

quantitative easing auctions of treasury bonds abstract the federal reserve uses reverse auctions to implement its purchases of treasury bonds in quantitative easing qe to evaluate dealers offers across multiple bonds the fed relies on its internal yield curve model fitted to secondary market bond prices from november 2010 to september 2011 a one standard deviation increase in the cheapness of a treasury bond how much the market price of the bond is below a model implied value increases the fed s purchase quantity of that bond by 276 million and increases the auction costs on that bond by 2 6 cents per 100 par value controlling for standard covariates our results suggest that the fed harvests gains from trades by purchasing undervalued bonds but strategic dealers extract some profits because the fed s relative values can be partly inferred from price data

the response of interest rates to us and uk quantitative easing we analyse declines in government bond yields following announcements by the federal reserve and the bank of england of plans to buy longer term debt using dynamic term structure models we decompose us and uk yields into expectations about future short term interest rates and term premiums we find that declines in us yields mainly reflected lower expectations of future short term interest rates while declines in uk yields appeared to reflect reduced term premiums thus the relative importance of the signalling and portfolio balance channels of quantitative easing may depend on market institutional structures and central bank communication policies

geographical labour mobility migration or commuting eliasson k lindgren u and westerlund o 2003 geographical labour mobility migration or commuting reg studies 37 827 837 in this paper we examine how individual labour market status and spatial variations in employment opportunities influence interregional job search behaviour and mobility decisions in sweden the econometric analysis is based on 290 000 individual observations and refers to the years 1994 95 the empirical results show that the probability of interregional labour mobility unexpectedly decreases with the accessibility to employment opportunities in neighbouring regions as expected the findings reveal that accessibility to job openings in surrounding regions significantly increases the likelihood of choosing commuting as the mobility mode moreover the empirical findings indicate that individual unemployment experience increases the likelihood of mobility as well as migration eliasson k lindgren u et westerlund o 2003 la mobilite geographique du travail la migration

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

migration and job change a multinomial logit approach abstract a multinomial logit model of residence and job change is developed and estimated both housing demand and job search characteristics are found to be significant determinants of the decision to migrate it is also found that both equilibrium and disequilibrium forces induce migration and job change finally the data do not appear to be ordered with respect to job and residence change contingencies with the exception of changing neither job nor residence relative to all other contingencies

optimal pricing with costly adjustment evidence from retail grocery prices in many theoretical models it is assumed that there are costs associated with adjusting prices in this paper the existence type and magnitude of such costs are investigated empirically a discrete choice dynamic programming model that nests fixed and variable costs is developed and econometric estimates of the adjustment cost function are obtained the data used to implement the model consist of weekly retail prices and sales of three brands of saltine crackers sold by four chains of grocery stores in a small u s town the study has several distinguishing characteristics first the data are highly disaggregate at the level of brand and store second variables are sampled at weekly intervals third the model nests fixed and variable adjustment costs and can therefore determine their relative importance finally the discrete choice model is both structural and dynamic

bidder behavior in multiunit auctions evidence from swedish treasury auctions we analyze a unique data set on multiunit auctions which contains the actual demand schedules of the bidders as well as the auction awards in over 400 swedish treasury auctions first we document that bidders vary their prices bid dispersion and the quantity demanded in response to increased uncertainty at the time of bidding second we find that bid shading can be explained by a winner s curse driven model in which each bidder submits only one bid despite the fact that the bidders in our data set use much richer bidding strategies third we explore the extent to which the received theories of multiunit auctions are able to offer insights into the bidder behavior we observe our empirical evidence is consistent with some of the predictions of the models of auctions that emphasize private information the winner s curse and the champion s plague while the models of multiunit auctions serve as useful guideposts our empirical findings also point to several new areas of research in multiunit auctions

the dynamics of markups and inventories in retailing firms this paper is concerned with the interaction between price and inventory decisions in retailing firms and its implications for the dynamics of markups and the existence of sales pro motions we consider a model where a monopolistically competitive retailer decides price and inventories and assumes lump sum costs when placing orders or changing nominal prices tn this model the existence of stockout probabilities and fixed ordering costs generate a cyclical price behaviour characterized by long periods without nominal price changes and short periods with very low prices i e sales promotions we estimate this model using a unique longitudinal dataset with information about retail and wholesale prices inventories orders and sales for several brands in a supermarket chain based on the estimated model we perform several counterfactual experi ments that show the important role that inventories and fixed ordering costs play in the dynamics of retail prices and the frequency of sales promotions in this dataset

special repo rates an empirical analysis duffie 1996 examines the theoretical impact of repo specials on the prices of treasury securities and concludes that all else the same an issue on special will carry a higher price than an otherwise identical issue we examine this hypothesis and find strong evidence in support of it we also examine whether the liquidity premium associated with on the run issues is due to repo specialness and find evidence of a distinct effect finally we investigate whether auction tightness and percentage awarded to dealers are related to subsequent specialness and find that both variables are generally significant underlying the cash market for u s treasury securities is the financing or repo market at any given time the repo rate for most treasury issues the general collateral rate is the same but a few issues are typically on special an issue on special has associated with it a repo rate that is less than the prevailing general collateral rate as a result the owner of a security that is on special is able to obtain below market financing rates via a repurchase agreement duffie 1996 examines the theoretical causes of repo specials and their impact on the prices of treasury securities in the context of a general equilibrium model his primary conclusion is that specialness will be priced in the cash market meaning that all else the same an issue on special or likely to go on special will carry a higher price than an otherwise identical issue we investigate this hypothesis using data on repo specials and find clear evidence in support of it we conclude that specialness is priced and that the magnitude of the cash market premium reflects both the future duration and magnitude of repo specialness we also examine whether the liquidity premium associated with on therun issues is due to repo specialness and find evidence of a distinct effect finally as a test of duffie s model we investigate whether auction tightness and percentage awarded to nonbank primary dealers are related to subsequent specialness the evidence is consistent with predictions with both variables generally significant

job moving residential moving and commuting a search perspective abstract we address the interrelationships between residential mobility labor market mobility and commuting the paper takes its starting point in recent findings in economic research which emphasise that job and residence relocation decisions imply forward looking decision making we examine job and residential mobility by means of bivariate models and interpret the outcomes in light of the search model

optimum pricing policy under stochastic inflation we describe aggregate inflation as a stochastic process in which the rate of change of the price level can be positive or zero where the times spent in each state are of random duration this class of processes includes two state markov chains and renewal processes as special cases it is shown that the optimal pricing policy of a monopolistic firm with non convex costs of price adjustment is s s in its real price i e its nominal price relative to the price level a basic certainty equivalence result is proved i e the firm behaves as if it faces a certain and fixed rate of inflation higher than the actual expected rate the difference between the two rates being a risk premium which depends on the real interest rate and the parameters of the stochastic process one can thus apply previous results from the case of certainty sheshinski and weiss review of economic studies 1977 to obtain comparative static results in particular one finds that an increase in the variance of expected inflation leads firms to choose a pricing policy with larger amplitude in real price the paper also addresses the question of consistency in firms expectations when the price level is determined by the firms actions in this paper we consider pricing policies of individual firms in an inflationary environment each firm expects the general price level to increase and must determine the rate of increase of its own price it is assumed that the firm incurs an adjustment cost when it changes its nominal price consequently firms choose to change prices occasionally rather than continuously

the effectiveness of alternative monetary policy tools in a zero lower bound environment this paper reviews alternative options for monetary policy when the shortterm interest rate is at the zero lower bound and develops new empirical estimates of the effects of the maturity structure of publicly held debt on the term structure of interest rates we use a model of risk averse arbitrageurs to develop measures of how the maturity structure of debt held by the public might affect the pricing of level slope and curvature term structure risk we find that these treasury factors historically were quite helpful for predicting both yields and excess returns over 1990 2007 the historical correlations are consistent with the claim that if in december 2006 the fed were to have sold off all its treasury holdings of less than 1 year maturity about 400 billion and use the proceeds to retire treasury debt from the long end this might have resulted in a 14 basis point drop in the 10 year rate and an 11 basis point increase in the 6 month rate we also develop a description of how the dynamic behavior of the term structure of interest rates changed after hitting the zero lower bound in 2009 our estimates imply that at the zero lower bound such a maturity swap would have the same effects as buying 400 billion in long term maturities outright with newly created reserves and could reduce the 10 year rate by 13 basis points without raising short term yields

anticipated and repeated shocks in liquid markets we show that treasury security prices in the secondary market decrease significantly before subsequent auctions and recover shortly after this price pattern implies a large issuance cost for the treasury department which is estimated to be between 9 and 18 basis points of the auction size for example this cost amounts to over half a billion dollars for issuing treasury notes alone in 2007 our results appear to be consistent with the hypothesis of primary dealers limited risk bearing capacity and the imperfect capital mobility of end investors in the treasury market e g federal agencies sovereign wealth funds pension funds and etc highlighting the important role of capital mobility even in the most liquid financial markets

valuing dealers informational advantage a study of canadian treasury auctions in many financial markets dealers have the advantage of observing the orders of their customers to quantify the economic benefit that dealers derive from this advantage we study detailed data from canadian treasury auctions where dealers observe customer bids while preparing their own bids in this setting dealers can use information on customer bids to learn about i competition that is the distribution of competing bids in the auction and ii fundamentals that is the ex post value of the security being auctioned we devise formal hypothesis tests for both sources of informational advantage in our data we do not find evidence that dealers are learning about fundamentals we find that the information about competition contained in customer bids accounts for 13 27 of dealers expected profits

discriminatory versus uniform treasury auctions evidence from when issued transactions abstract we use when issued transactions data to assess the treasury s current experiment with uniform auctions when issued volume is higher under uniform as compared to discriminatory auctions suggesting a higher information release which should reduce pre auction uncertainty and the winner s curse under uniform auctions when issued volatility falls after the auction and again after the outcome announcement the pattern is the opposite for discriminatory auctions this is further evidence that uniform auctions increase pre auction information and lower the short squeeze a direct comparison of markups in uniform and discriminatory auctions yields mixed results

the federal reserve s large scale asset purchase programmes rationale and effects we provide empirical estimates of the effect of large scale asset purchases lsaps on longer term us treasury yields within a framework that allows for several transmission channels including the scarcity channel associated with the preferred habitat literature and the duration channel associated with interest rate risk we also clarify lsaps role in the broader context of historical monetary policy strategy results indicate that lsap style operations mainly impact longer term rates via the nominal term premium within that premium the response is predominantly embodied in the real term premium the scarcity and duration channels both seem to be of considerable importance

magazine prices revisited this paper examines price adjustment behaviour in the magazine industry in a frequently cited study cecchetti 1986 constructs a reduced form s s model for firms cecchetti assumes that a firm s pricing rules are fixed for non overlapping three year intervals and estimates the model using a conditional logit specification from chamberlain 1980 the estimates are inconsistent however due to the duration dependent specification of the model two alternative specifications are used to obtain consistent estimation the consistent estimates continue to provide strong evidence in favour of state dependent pricing models but only weak evidence on the behaviour of price adjustment costs copyright 2006 john wiley sons ltd

price rigidities and market structure conventional wisdom has it that a large part of the explanation of keynesian unemployment is the observed rigidities of wages and prices what has been lacking however is a satisfactory theory or conjunction of theories which explains how wages and prices can be at non market clearing levels the objective of this paper is to sketch out several alternative theoretical explanations of this phenomenon each in contrast with keynesian theory is consistent with the observation that as the economy goes into a recession real product wages do not increase and may in fact decrease all of the theories assume rational profit maximizing firms and all entail some important departure from the standard competitive paradigm the first three explanations represent minor adaptations of standard models

increasing returns and the foundations of unemployment theory current approaches to macroeconomic theory divide roughly into two basic schools of thought one approach typically associated with rational expectations views the economy as basically at or near walrasian market clearing equilibrium in which case it becomes very difficult to explain away convincingly the undeniable persistence at times of involuntary unemployment another approach views the underemployed economy as being in a state of temporary fixed price disequilibrium in which case aside from having to repress suspicions that the essence of effective demand failure might not have to do with prices fixed at wrong values there is a lot of rationalising to be done about why profitable adjustments are so slow this paper argues that something like an internally consistent theory of steady state involuntary unemployment is possible and even plausible the cornerstone of this third approach is increasing returns to scale which blocks unemployed agents from breaking out of a low level equilibrium trap unless there is overall coordination or stimulation a simple model is presented which contains the basic ideas

underpricing in discriminatory and uniform price treasury auctions this paper compares the newer uniform price u s treasury auctions to the traditional discriminatory mechanism and examines the extent to which the auction mechanisms are responsible for underpricing empirically i find that even for the newer uniform price auctions the average price received by the treasury is less than the price of the same securities in the concurrent secondary market although this underpricing is reduced by half relative to the older mechanism from the summary statistics released by the treasury i calibrate common value auction models for the two mechanisms and predict the level of underpricing in each auction i find that the observed magnitude of underpricing in the auctions is consistent with the model s predictions

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

what does monetary policy do to long term interest rates at the zero lower bound this article uses a structural var with daily data to identify the effects of monetary policy shocks on various longer term interest rates since the federal funds rate has been stuck at the zero lower bound the var is identified using the assumption that monetary policy shocks are heteroskedastic monetary policy shocks have especially high variance on days of fomc meetings and certain speeches while there is otherwise nothing unusual about these days a complementary high frequency event study approach is also used i find that stimulative monetary policy shocks lower treasury and corporate bond yields but the effects die off fairly fast
