house price dynamics with dispersed information abstract we use a user cost model to study how dispersed information affects the equilibrium house price in the model agents are disparately informed about local economic conditions consume housing services and speculate on price changes optimists who expect high house price growth buy in anticipation of capital gains pessimists who expect capital losses prefer to rent because of short selling constraints on housing pessimistic expectations are not incorporated in the price of owned houses and the equilibrium price is higher and more volatile relative to the benchmark case of common information we present evidence supporting the model s predictions in a panel of us cities

speculative investor behavior and learning as traders learn about the true distribution of some asset s dividends a speculative premium occurs as each trader anticipates the possibility of reselling the asset to another trader before complete learning has occurred small differences in prior beliefs lead to large speculative premiums during the learning process this phenomenon helps explain a paradox concerning the pricing of initial public offerings the result casts light on the significance of the common prior assumption in economic models

strategic pricing with customer rationing the case of primary metals firms in primary metal industries often charge subcompetitive prices and in periods of high demand they may ration their customers a model is developed to ex plain these empirical regularities in the model firms with market power are aware that the price they charge today affects their demand tomorrow in addition the strategic interaction among firms reinforces this intertemporal effect in the equilibrium of the two stage game oligopolists can price below marginal cost and when capacity constraints are introduced the equilibrium can involve rationing model predictions are assessed using market structure and technology data for several primary metal industries

long term contracting and multiple price systems this article examines product markets in which long term contracts and spot transactions coexist such markets are characterized by multiple price systems wherein adjustment to supply and demand shocks occurs through spot prices while contract prices are fixed or adjust slowly the authors derive the existence of contracts as well as the equilibrium fraction of spot trade in the framework of an optimizing model and analyze the effects of shocks on market equilibrium when some buyers and sellers locked in contractually the model is employed to interpret the change in the copper market from a multiple price system to one characterized solely by spot trade copyright 1992 by university of chicago press

uniform compliance costs for mineral commodities who gains and who loses changes in energy and nonfuelmineral production consumption and net export revenue that result from environmental protection are estimated by income class and geographic region unlike previous assessments of unilateral adoption of standards i assume that all producers incur equal cleanup costs adjustment is therefore accomplished through changes in prices and quantities rather than altered trade patterns the estimated magnitude of worldwide changes is not large moreover many poor countries are forecast to benefit since their terms of trade improve however the problem of obtaining foreign exchange for investment remains a financing scheme that divorces efficiency from equity is suggested

wall street and the housing bubble we analyze whether mid level managers in securitized finance were aware of the housing bubble and a looming crisis in 2004 2006 using their personal home transaction data we find little evidence of them timing the bubble or exercising cautious behavior in purchasing homes relative to two uninformed control groups one composed of non housing equity analysts and the other of non real estate lawyers to the extent that the practice of securitization may have led to lax screening of subprime borrowers the average person in our sample did not expect it to lead to problems in the wider housing market our findings suggest the need to expand the incentives based view of the crisis to incorporate a role for distorted beliefs

bubbles crashes and endogenous expectations in experimental spot asset markets1 spot asset trading is studied in an environment in which all investors receive the same dividend from a known probability distribution at the end of each of t 15 or 30 trading periods fourteen of twenty two experiments exhibit price bubbles followed by crashes relative to intrinsic dividend value when traders are experienced this reduces but does not eliminate the probability of a bubble the regression of changes in mean price on lagged excess bids number of bids minus the number of offers in the previous period p pt a f b 1 o l supports the hypothesis that a e d the one period expected value of the dividend and that f 0 where excess bids is a surrogate measure of excess demand arising from homegrown capital gains losses expectations thus when bt 1 o goes to zero we have convergence to rational expectations in the sense of fama 1970 that arbitrage becomes unprofitable the observed bubble phenomenon can also be interpreted as a form of temporary myopia tirole 1982 from which agents learn that capital gains expectations are only temporarily sustainable ultimately inducing common expectations or priors tirole 1982 four of twenty six experiments all using experienced subjects yield outcomes that appear to the chart s eye to converge early to rational expectations although even in these cases we get 0 and small price fluctuations of a few cents that invite scalping

house prices home equity based borrowing and the u s household leverage crisis us household leverage sharply increased in the years preceding the 2007 eco nomic recession the top panel of figure 1 shows the steady rise in household debt since 1975 which accelerated beginning in 2002 in just five years the household sector doubled its debt balance in comparison the contemporaneous increase in corporate debt was modest the middle panel shows that the increase in household debt from 2002 to 2007 translated into a striking rise in household leverage as mea sured by the debt to income ratio during the same time period corporate leverage declined the dramatic absolute and relative rise in us household leverage from 2002 to 2007 is unprecedented compared to the last 25 years one reason for the rapid expansion in household leverage during this period is that mortgage credit became more easily available to new home buyers mian and sufi 2009 strong house price appreciation from 2002 to 2006 however which may have been fueled by the availability of mortgage credit to a riskier set of new home buyers could also have had an important feedback effect on household lever age through existing homeowners given that 65 percent of us households already owned their primary residence before the acceleration in house prices the feedback from house prices to borrowing may be an important source of the rapid rise in household leverage that preceded the economic downturn our central goals in this study are to estimate how homeowner borrowing responded to the increase in house prices and to identify which homeowners responded most aggressively we examine this home equity based borrowing channel using a dataset consisting of anonymous individual credit files of a national consumer credit bureau agency we follow a random sample of over 74 000 us homeowners who owned their homes as of 1997 at an annual frequency from the end of 1997 until the end of 2008 the bottom panel of figure 1 plots the growth in debt of 1997 homeowners over time and shows that existing homeowners borrow significantly more debt as their house prices appreciate from 2002 to 2006 while the aggregate trend is suggestive

endogenous gentrification and housing price dynamics in this paper we begin by documenting substantial variation in house price growth across neighborhoods within a city during citywide housing price booms we then present a model which links house price movements across neighborhoods within a city and the gentrification of those neighborhoods in response to a citywide housing demand shock a key ingredient in our model is a positive neighborhood externality individuals like to live next to richer neighbors this generates an equilibrium where households segregate based upon their income in response to a citywide demand shock higher income residents will choose to expand their housing by migrating into the poorer neighborhoods that directly abut the initial richer neighborhoods the in migration of the richer residents into these border neighborhoods will bid up prices in those neighborhoods causing the original poorer residents to migrate out we refer to this process as endogenous gentrification using a variety of data sets and using bartik variation across cities to identify city level housing demand shocks we find strong empirical support for the model s predictions

the housing market s of san diego this paper uses an assignment model to understand the cross section of house prices within a metro area movers demand for housing is derived from a lifecycle problem with credit market frictions equilibrium house prices adjust to assign houses that dier by quality to movers who dier by age income and wealth to quantify the model we measure distributions of house prices house qualities and mover characteristics from micro data on san diego county during the 2000s boom the main result is that cheaper credit for poor households was a major driver of prices especially at the low end of the market

housing demand during the boom the role of expectations and credit constraints i use a life cycle model of housing demand to infer expectations about house prices and home equity requirements for the housing boom of the 2000s from observed household choices expectations and credit constraints are separately identified from the intensive and extensive margins of housing demand the main results are that 1 expected price growth was close to average long run growth 2 home equity requirements were lax initially but tightened after the bust and 3 subjective uncertainty about future price growth was large given the option to default on mortgage debt greater price uncertainty leads to higher optimal household leverage

valuing managerial flexibility an application of real option theory to mining investments abstract the value of managerial flexibility is assessed using data on prices costs grades reserves ore extraction and metal output for a panel of canadian copper mines a real option model is estimated and solved for project and option values most empirical researchers i consider the initial investment decision but neglect flexible operation thereafter ii assume that price is stochastic but ignore cost and reserve uncertainty and iii model price as a nonstationary stochastic process the evolution of three state variables price cost and reserves is assessed here differences in assumptions compared to others are found to lead to large differences in estimated project and option values

belief disagreements and collateral constraints belief disagreements have been suggested as a major contributing factor to the recent subprime mortgage crisis this paper theoretically evaluates this hypothesis i assume that optimists have limited wealth and take on leverage so as to take positions in line with their beliefs to have a significant effect on asset prices they need to borrow from traders with pessimistic beliefs using loans collateralized by the asset itself since pessimists do not value the collateral as much as optimists do they are reluctant to lend which provides an endogenous constraint on optimists ability to borrow and to influence asset prices i demonstrate that the tightness of this constraint depends on the nature of belief disagreements optimism concerning the probability of downside states has no or little effect on asset prices because these types of optimism are disciplined by this constraint instead optimism concerning the relative probability of upside states could have significant effects on asset prices this asymmetric disciplining effect is robust to allowing for short selling because pessimists that borrow the asset face a similar endogenous constraint these results emphasize that what investors disagree about matters for asset prices to a greater extent than the level of disagreements when richer contracts are available relatively complex contracts that resemble some of the recent financial innovations in the mortgage market endogenously emerge to facilitate betting

urban decline and durable housing urban decline is not the mirror image of growth and durable housing is the primary reason the nature of decline is so different this paper presents a model of urban decline with durable housing and verifies these implications of the model 1 city growth rates are skewed so that cities grow more quickly than they decline 2 urban decline is highly persistent 3 positive shocks increase population more than they increase housing prices 4 negative shocks decrease housing prices more than they decrease population 5 if housing prices are below construction costs then the city declines and 6 the combination of cheap housing and weak labor demand attracts individuals with low levels of human capital to declining cities

the effect of housing on portfolio choice we show that characterizing the effects of housing on portfolios requires distinguishing between the effects of home equity and mortgage debt we isolate exogenous variation in home equity and mortgages by using differences across housing markets in house prices and housing supply elasticities as instruments increases in property value holding home equity constant reduce stockholdings while increases in home equity wealth holding property value constant raise stockholdings the stock share of liquid wealth would rise by 1 percentage point 6 of the mean stock share if a household were to spend 10 less on its house holding fixed wealth

causes of sprawl a portrait from space we study the extent to which u s urban development is sprawling and what determines differences in sprawl across space using remote sensing data to track the evolution of land use on a grid of 8 7 billion 30 30 meter cells we measure sprawl as the amount of undeveloped land surrounding an average urban dwelling the extent of sprawl remained roughly unchanged between 1976 and 1992 although it varied dramatically across metropolitan areas ground water availability temperate climate rugged terrain decentralized employment early public transport infrastructure uncertainty about metropolitan growth and unincorporated land in the urban fringe all increase sprawl

why there are organized futures markets i shall present an explanation of the existence of organized futures markets with more predictive power than the two prevailing rival views my explanation briefly is this an organized futures market facilitates trade among strangers one of the rival prevailing views is a defense of futures trading it asserts that an organized futures market furnishes legitimate businessmen with a means of hedging so that they can obtain insurance against price risk the other prevailing view is an attack on organized futures markets it asserts that such markets enable speculators to manipulate prices to the detriment of outsiders who are less well informed and to the detriment of legitimate businessmen such as farmers the attack on organized futures markets likens them to gambling casinos the defense sees them as a form of insurance neither the attack nor the defense is valid the correct explanation is closely related to why we conduct trade using money instead of by barter

arrested development theory and evidence of supply side speculation in the housing market this paper incorporates speculation into the standard supply and demand framework used to analyze housing booms and busts speculation reverses the common intuition that elastic housing supply attenuates housing booms housing market frictions make land a more attractive speculative investment than housing as a result undeveloped land both facilitates construction and intensies

a welfare criterion for models with distorted beliefs this paper proposes a welfare criterion for economies in which agents have heterogeneously distorted beliefs instead of taking a stand on whose belief is correct our criterion asserts an allocation to be belief neutral ine cient if it is ine cient under any convex combination of agents beliefs while this criterion gives an incomplete ranking of social allocations it can identify negative sum speculation in a broad range of prominent models with distorted beliefs

inventories market structure and price volatility abstract the effect of inventories on the level and volatility of price is analyzed under alternative market structures in a fairly general setting it is shown that inventories have no effect on the average level of prices in a cournot duopoly in the absence of depreciation the effect of storage on price volatility is analyzed in a more restrictive linear quadratic setting in which it is found that imperfectly competitive producers make less use of inventories for smoothing random fluctuations than is efficient the effect of market structure on price volatility depends on whether demand shocks or cost shocks are more important

tax subsidies to owner occupied housing an asset market approach inflation reduces the effective cost of homeownership and raises the tax subsidy to owner occupation this paper presents an asset market model of the housing market and estimates how changes in the expected inflation rate affect the real price of houses and the equilibrium size of the housing capital stock simulation results suggest that the accelerating inflation of the 1970s which substantially reduced homeowners user costs could have accounted for as much as a 30 percent increase in real house prices persistent high inflation rates could lead ultimately to a sizable increase in the stock of owner occupied housing

can high costs justify weak demand for the home equity conversion mortgage home equity conversion mortgages hecms implicitly bundle nondefaultable credit lines with put options that let borrowers or their heirs sell mortgaged homes for the credit line limit when borrowers move or die the put option s value net of closing costs bounds hecm s value to borrowers below older homeowners weak demand is commonly attributed to hecm s high costs and the government prices insurance intending to avoid subsidy however simulations indicate put value has often exceeded closing costs even ignoring other embedded options and using backward looking expectations near the recent price cycle peak these results make weak demand more puzzling

a nation of gamblers real estate speculation and american history the great housing convulsion that buffeted america between 2000 and 2010 has historical precedents from the frontier land boom of the 1790s to the skyscraper craze of the 1920s but this time was different there was far less far less real uncertainty about fundamental economic and geographic trends making the convulsion even more puzzling during historic and recent booms sensible models could justify high prices on the basis of seemingly reasonable projections about stable or growing prices the recurring error appears to be a failure to anticipate the impact that elastic supply will eventually have on prices whether for cotton in alabama in 1820 or land in las vegas in 2006 buyers don t appear to be irrational but rather cognitively limited investors who work with simple heuristic models instead of a comprehensive general equilibrium framework low interest rates rarely seem to drive price growth under priced default options are a more common contributor to high prices the primary cost of booms has not typically been overbuilding but rather the financial chaos that accompanies housing downturns

market structure marketing method and price instability data for metals sold on commodity exchanges and at prices set by producers are used to test the relationship between the organization of markets and the behavior of prices on the production side the question is whether prices are more stable in concentrated industries and on the sales side the question is whether markets where buyers are consumers have more stable prices than those with consumers and speculators the recent increase in metal price instability is explained by changes in the market structure and organization variables foremost is increased reliance on commodity exchanges declines in concentration are of less importance

commodity price stabilization in imperfect or cartelized markets most studies of commodity price stabilization assume that all agents behave competitively however many commodities suitable for stockpiling are produced by countries with a significant share of the world market and commodity agreements themselves often result in cartelization of the market the paper explores the consequences of market power for the choice of storage rule and the degree of price stabilization it finds that with linear demand dominant producers choose more stable prices than under perfect competition and price stability increases with their market share with constant elastic demand the competitive degree of price stabilization is achieved

pre emptive patenting joint ventures and the persistence of oligopoly abstract gilbert and newbery 1982 have examined pre emptive patenting and the persistence of monopoly the present paper considers pre emptive patenting when there are several incumbent firms rather than just one it is shown why the incumbent oligopolists behaving non cooperatively might fail to deter entry this suggests that a joint venture in r and d might be a useful entry deterring device insofar as it pools the incumbents incentives to prevent entry this is indeed the case for small innovations but for large innovations the formation of a joint venture weakens the incumbents incentive to innovate by removing the competitive stimulus between them

quantity leadership and social inefficiency a game of simultaneous free entry and sequential output choices is analyzed firms enter simultaneously in stage 1 by paying a fixed cost and they choose output levels sequentially in subsequent stages at the subgame perfect equilibrium of the game the production level of a firm is decreasing with the order of the firm in the decision making the firm that is the last to choose output produces the same amount as a typical firm in the standard symmetric simultaneous moves cournot game moreover industry output and market price are identical in the sequential and the symmetric cournot games it follows that in the sequential game there are fewer active firms and higher total surplus than in the standard symmetric cournot game strategic asymmetry results in higher concentration and higher total surplus without an increase in price

untested hypotheses in non renewable resource economics the present paper reviews the literature on the empirical implications of the hotelling rule and suggests directions for further research in this area

the role of price spillovers in the american housing boom abstract one of the striking features of the last u s housing boom was the heterogeneity in the timing of its onset across local markets in this paper we exploit this heterogeneity to estimate the extent to which the boom was spread via spatial spillovers from one market to another our analysis focuses on spillovers that occur around the time that a local market enters its boom which we identify using sharp structural breaks in house price growth rates on the extensive margin there is evidence that the likelihood of a market booming increases substantially if nearby neighbors boom on the intensive margin we also find statistically significant but economically modest effects of the size of a neighbor s boom on subsequent price growth in nearby markets these affects appear to be unrelated to local market fundamentals suggesting a potential role for non rational factors

scarcity resource price uncertainty and economic growth over the course of the past decade significant steps have been taken to empirically link indicators of resource scarcity to changes in economic growth this paper extends this previous literature in two ways first rather than concentrating exclusively on energy we focus on the technological change embodied in the prices of an array of complementary natural resource inputs second we investigate using g arch methods the importance of resource price uncertainty as well as resource price levels on aggregate economic growth we find that output growth is significantly influenced by both resource price levels and resource price uncertainty

housing investment in the united states a supply determined model of housing investment is estimated from quarterly data over the 1963 83 period the model is built on dynamic marginal cost pricing considerations and allows short and long run supply elasticities to differ these are estimated as 1 0 and 3 0 respectively but most of the long run response occurs within 1 year rapid adjustment speed and the sizable long run elasticity of supply are important factors in understanding the volatility of housing investment the data also suggest some anomalies in the expected present value theory of asset pricing for housing capital

a near rational model of the business cycle with wage and price inertia this paper presents a model in which insignificantly suboptimal behavior causes aggregate demand shocks to have significant real effects the individual loss to agents with inertial price wage behavior is second order in terms of the parameter describing the shock while the effect on real economic variables is first order thus significant changes in business activity can be generated by anticipated money supply changes provided that some agents are willing to engage in nonmaximizing behavior which results in small losses

oligopolistic entry deterrence under incomplete information recent work has investigated the effects of asymmetric information between an incumbent firm and a potential entrant this study extends the analysis to allow the initial market structure to be a noncooperative oligopoly we show that there is a bayesian nash equilibrium in which the incumbent firms although unable to collude strategically deter entry that would have occurred under complete information in contrast to the past limit pricing literature it is a high price that deters entry as it signals to the potential entrant that this is a high cost industry extending the model to allow for multiple potential entrants we find that increasing the degree of potential competition raises the preentry price and reduces the likelihood of entry

misinformed speculators and mispricing in the housing market this paper examines the contribution of out of town second house buyers to mispricing in the housing market we show that demand from out of town second house buyers during the mid 2000s predicted not only house price appreciation rates but also implied to actual rent ratio appreciation rates a proxy for mispricing we then apply a novel identification strategy to address the issue of reverse causality we give supporting evidence that out of town second house buyers behaved like misinformed speculators earning lower capital gains misinformed and consuming smaller dividends speculators

higher prices at canadian gas pumps international crude oil prices or local market concentration an empirical investigation there is little consensus on whether higher retail gasoline prices in canada are the result of international crude oil price fluctuations or local market power exercised by large vertically integrated firms i find that although both increasing local market concentration and higher average monthly wholesale prices are positively and significantly associated with higher retail prices wholesale prices are more important than local market concentration similarly crude oil prices are more important than the number of local wholesalers in determining wholesale prices these results suggest that movements in gasoline prices are largely the result of input price fluctuations rather than local market structure

speculation and risk sharing with new financial assets while the traditional view of nancial innovation emphasizes the risk sharing role of new nancial assets belief disagreements about these assets naturally lead to speculation which represents a powerful economic force in the opposite direction this paper investigates the eect of nancial innovation on portfolio risks in an economy when both the risk sharing and the speculation forces are present financial assets provide hedging services but they are also subject to speculation because traders do not necessarily agree about their payos i de ne the average variance of traders net worths as a measure of portfolio risks for this economy and i decompose it into two components the uninsurable variance de ned as the average variance that would obtain if there were no belief disagreements and the speculative variance de ned as the residual variance that results from speculative trades based on belief disagreements financial innovation always decreases the uninsurable variance because new assets increase the possibilities for risk sharing my main result shows that nancial innovation also always increases the speculative variance this is true even if traders completely agree about the payos of new assets the intuition behind this result is the hedge more bet more eect traders use new assets to hedge their bets on existing assets which in turn enables them to place larger bets and take on greater risks my second set of results concern endogenous nancial innovation when belief disagreements are su ciently large a pro t seeking market maker introduces assets that maximize the average variance among all possible choices completely disregarding the risk sharing motive for nancial innovation my third set of results concern a calibration of the model in the context of the gdp indexed assets proposed by athanasoulis and shiller 2001 when traders have reasonable amounts of belief disagreements these assets would have the unintended consequence of increasing their consumption risks

price adjustments by a gasoline retail chain we use daily data to examine price responses in the swedish gasoline market to changes in the rotterdam spot price exchange rates and taxes the distribution of price adjustments by a leading retail chain for the period january 1980 to december 1996 is symmetric with no small adjustments an error correction model shows that in the short run prices gradually move towards the long run equilibrium in response to cost shocks there is some evidence that also in the short run prices are stickier downwards than upwards prices respond more rapidly to exchange rate movements than to the spot market price our analysis emphasizes that to fully understand price adjustments it is necessary to examine data sets where the sample frequency at least matches that of price adjustments

commodity agreements and commodity markets lessons from tin in what follows we study the history of the tin market over the period i982 5 important questions this exercise will help to answer are was the collapse of the tin market a failure of the buffer stock operation and was it inevitable was the activity of the buffer stock a commodity market manipulation was there a deficiency in the drafting of the tin agreement was there a failure of commodity market regulation more generally while it has long been recognised that stabilisation schemes are vulnerable to speculative attacks the interconection between buffer stock managements and futures markets has not been explored in this sense our historical analysis will

liquidity vs wealth in household debt obligations evidence from housing policy in the great recession we exploit variation in mortgage modifications to disentangle the impact of reducing long term obligations with no change in short term payments wealth and reducing short term payments with no change in long term obligations liquidity using regression discontinuity and difference in differences research designs with administrative data measuring default and consumption we find that principal reductions that increase wealth without affecting liquidity have no effect while maturity extensions that increase only liquidity have large effects this suggests that liquidity drives default and consumption decisions for borrowers in our sample and that distressed debt restructurings can be redesigned with substantial gains to borrowers lenders and taxpayers

swings in commercial and residential land prices in the united states abstract we use a large dataset of land sales dating back to the mid 1990s to construct land price indexes for 23 msas in the united states and for the aggregate of those msas the price indexes show a dramatic increase in both commercial and residential land prices over several years prior to their peak in 2006 2007 and a steep descent since then these fluctuations have exceeded those in well known indexes of home prices and commercial real estate prices because those indexes price a bundle of land and structures this comparison implies that land prices have been more volatile than structures prices over this period this result is a key element of the land leverage hypothesis which holds that home prices and commercial property prices will be more volatile all else equal in areas where land represents a larger share of real estate value

a closer look at the effect of market growth on industries profits everybody talks about the relation of industries profit rates to their markets rates of growth but nobody does anything about it specifically researchers have confirmed the effect of the growth of nominal output on profits in many multivariate studies without specifying closely the hypothesis under test or the measure of demand growth appropriate to test it a profits growth relationship could stem from several mechanisms the lagged adaptation of capacity to unexpected changes in demand reactions of oligopolists to disturbances in their consensus etc these mechanisms how and where they work hold their own normative interest therefore knowing what behavior and what structure lying behind it accounts for the profits growth relationship should do more than improve the specifications of our studies of allocative efficiency it should also expand our knowledge of adaptive processes that are important and hard to observe directly in this paper we shall synthesize the available explanations of why changes in market demand should affect an industry s profits then present a statistical test of the relative significance of the competing explanations

the response by the norwegian aluminium industry to changing market structure abstract this paper analyses how changes in market structure have affected the margins measured by the lerner index of norwegian aluminium plants instead of showing the expected negative trend due to increased competition internationally the margins are found to move procyclically around a constant that significantly exceeds zero three explanations for this stability in the levels of the margins are identified a better exploitation of scale economies increased productivity and product specialisation which allows norwegian producer prices to increase more rapidly than the international reference price

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

risk and return on long lived tangible assets abstract assuming rational expectations a specialization of ross arbitrage pricing theory is used to obtain a simple securities market valuation formula when dividends follow linear stochastic processes the implications of this model for the use of accounting data to measure risk and for capital budgeting are explored a new measure of riskiness based on accounting data is derived and the use of risk adjusted discount rates is evaluated

strategic deterrence of sequential entry into an industry industrial entry deterrence is typically studied in a setting where an established firm or firms confront and attempt to deter a single potential competitor during the evolution of most industries however a sequence of firms enters or attempts to enter at distinct points in time consideration of issues arising from sequential entry fundamentally alters the qualitative nature of the deterrence decision undertaken by incumbent firms within a sequential setting counterintuitive behavior may be observed specifically numerous government policies designed to decrease industrial concentration penalties for anticompetitive practices subsidization of entry consent decrees restructuring industries may have the opposite effect

the determinants and welfare implications of us workers diverging location choices by skill 1980 2000 abstract from 1980 to 2000 the rise in the us college high school graduate wage gap coincided with increased geographic sorting as college graduates concentrated in high wage high rent cities this paper estimates a structural spatial equilibrium model to determine causes and welfare consequences of this increased skill sorting while local labor demand changes fundamentally caused the increased skill sorting it was further fueled by endogenous increases in amenities within higher skill cities changes in cities wages rents and endogenous amenities increased inequality between high school and college graduates by more than suggested by the increase in the college wage gap alone jel d31 i26 j24 j31 j61 r23

an empirical stationary equilibrium search model of the housing market this article specifies and estimates a computationally tractable stationary equilibrium model of the housing market the model is rich and incorporates many of its unique features buyers and sellers simultaneous search behavior heterogeneity in their motivation to trade transaction costs a trading mechanism with posting prices and bargaining and the availability of an exogenous advertising technology that induces endogenous matching estimation uses maximum likelihood methods and multiple listing services data the estimated model is used to simulate housing market outcomes when a the amount of information displayed on housing listings increases and b real estate agent s commission rates change

the price effect of expanding fish auction markets abstract fish markets can be expanded by two means first by attracting newcomers in a local trading room and secondly by allowing remote bidders to participate in both cases electronic systems have played a key role in french primary fish markets the computerisation of trading rooms started in the mid 1980s while connection through intranet or internet systems first started in the mid 1990s and then has spread more actively in france since 2007 however the socioeconomic impact on prices for example of expanding markets by electronic means is far from being clearly predictable first based on an econometric analysis this article presents evidence of increases in price level and variability after the implementation of local electronic auction systems secondly a comprehensive survey of the 40 fish auction markets in france brings additional information about the effects of electronic remote bidding on fish prices the analysis of these two empirical outcomes uses the cross fertilization of the positivist auction theory in economics with the constructionist approach of actor network theory ant in sociology to enrich the potential hypotheses lying behind the study of the structural impact of electronic systems on market prices

price wars and the stability of collusion a study of the pre world war i bromine industry between 1885 and 1914 us bromine producers colluded to raise prices and pro ts this collusion was disrupted by price wars bromine price wars are compared with the green porter and abreu pearce stacchetti models some price wars resulted from the imperfect monitoring problems which motivate these models several empirical implications of the aps model are borne out but the bromine industry s price wars were generally milder than contemplated by aps more severe price wars were part of a bargaining process in which rms tried to force renegotiation to a new collusive equilibrium with a diierent distribution of rents

oil and energy price volatility it is commonly believed that since the 1973 oil crisis oil and energy prices have been more volatile than other commodity prices this study examines monthly producer prices for thousands of products over the period january 1945 through august 2005 the results show that crude oil refined petroleum and natural gas prices are more volatile than prices for about 95 of products sold by domestic producers relative to crude commodities however crude oil prices are currently more volatile than about 65 of other products and oil price volatility first exceeded the median for crude commodities following the 1986 drop in oil prices

the many approaches to the study of monopolistic competition abstract what are the key questions in the study of monopolistic competition oligopoly theory and allied topics dealing with competition among the few a specification and discussion of some of these questions is given in particular both problems and their resolution in studying oligopoly in a closed economy and the reconciliation of cooperative and non cooperative models of oligopolistic competition with general equilibrium theory is discussed some problems with dynamics are noted in particular the limitations of the non cooperative equilibrium solution are considered questions are raised concerning the domain of application of perfect equilibria the treatment of subjective probabilities and non symmetric information

the rigidity of prices this paper uses evidence on individual transaction prices to analyze price behavior the evidence shows that for many transactions pricesremain rigid for periods exceeding one year the rigidity of price ispositively correlated with industry concentration for several productsthe correlation of price changes across buyers is low the paper alsoinvestigates the relationship between price rigidity price change andthe length of time a buyer and seller have been doing business together the author interprets the evidence as emphasizing the importance of nonprice rationing and the inadequacy of models in whichprice movements alone clear markets copyright 1986 by american economic association

sticky prices in a dynamic oligopoly an investigation of s s thresholds abstract the strategic implications of costly price adjustment are investigated empirically i assume that managers are engaged in a state space game and ask if the dynamic considerations that arise when they condition their choices on the state cause prices to be more or less rigid than when players use more myopic pricing rules the answer to this question depends on a parametric specification of the problem that lends itself to empirical assessment the micro panel data used to investigate this issue consist of weekly prices sales costs and promotional activity for three brands of saltine crackers sold by four chains of grocery stores in a small us town i find that in this market strategic behavior exacerbates price rigidity the thresholds are wider and the time between changes is longer than would be observed in a more myopic setting

beauty contests and iterated expectations in asset markets in a financial market where traders are risk averse and short lived and prices are noisy asset prices today depend on the average expectation today of tomorrow s price thus iterating this relationship the date 1 price equals the date 1 average expectation of the date 2 average expectation of the date 3 price this will not in general equal the date 1 average expectation of the date 3 price we show how this failure of the law of iterated expectations for average belief can help understand the role of higher order beliefs in a fully rational asset pricing model and explain over reaction to noisy public information

industrialization and the demand for mineral commodities abstract this paper uses a new data set that begins in 1840 to investigate how industrialization affects the derived demand for mineral commodities i establish that there is substantial heterogeneity in the long run effect of manufacturing output on demand across five commodities a one percent increase in per capita manufacturing output leads to an approximately 1 5 percent increase in aluminum demand and a roughly 1 percent rise in copper demand estimated elasticities for lead tin and zinc are below unity my results suggest that the experience of japan and south korea s industrialization for example may be used to infer the impact of china s industrialization on future demand for metals the results imply substantial differences across commodities with regard to future demand adjustment to equilibrium takes 7 13 years which helps explain the long duration of commodity price fluctuations

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

do markets differ much this essay reports the results of a crosssection study of differences in accounting profitability that sheds light on some basic controversies in industrial economics most previous cross section studies in this field have been concerned with testing hypotheses about structural coefficients in models meant to apply to essentially all markets as we have learned more about the difficulties of constructing such general models and of performing tests on their structural parameters properly structural cross section analysis has fallen out of fashion in contrast to most of the cross section literature the analysis reported here is fundamentally descriptive it does not attempt directly to estimate or to test hypotheses about structural parameters i hope to show by example that one can perform illuminating analysis of cross section data without a host of controversial maintained hypotheses cross section data can yield interesting stylized facts to guide both general theorizing and empirical analysis of specific industries even if they cannot easily support full blown structural estimation one can view the sort of search for stylized facts conducted here as either a replacement for or an input to interindustry structural estimation depending on one s feeling about the long run potential of that research approach this study also departs from much of the cross section literature by being fundamentally concerned with the importance of various effects not just with coefficient signs and t statistics in particular this essay provides estimates of the relative importance of firm market and market share differences in the determination of business unit divisional profitability in u s manufacturing using 1975 data from the line of business program of the u s federal trade commission ftc i find support neither for the existence of firm effects nor for the importance of market share effects moreover while industry effects apparently exist and are important they appear to be negatively correlated with seller concentration in these data section i relates firm market and share effects to current issues and controversies in industrial economics and thus supplies the motivation for our empirical analysis the remainder of the essay treats the data and

inflation and relative price variability abstract theoretical explanations of the inflation relative price variability relationship are often observationally equivalent this paper compares two theoretical models menu costs and imperfect information the microfoundations of the models are used to generate new testable differences between the theories

asset float and speculative bubbles we model the relationship between asset float tradeable shares and speculative bubbles investors with heterogeneous beliefs and short sales constraints trade a stock with limited float because of insider lockups a bubble arises as price overweighs optimists beliefs and investors anticipate the option to resell to those with even higher valuations the bubble s size depends on float as investors anticipate an increase in float with lockup expirations and speculate over the degree of insider selling consistent with the internet experience the bubble turnover and volatility decrease with float and prices drop on the lockup expiration date

supply constraints and housing market dynamics abstract although the volatility of house prices is often ascribed to demand side factors constraints on housing supply have important and little studied implications for housing dynamics i illustrate the strong relationship between the volatility of house prices and the regulation of new housing supply i then employ a dynamic structural model of housing investment to investigate the mechanisms underlying this relationship i find that supply constraints increase volatility through two channels first regulation lowers the elasticity of new housing supply by increasing lags in the permit process and adding to the cost of supplying new houses on the margin second geographic limitations on the area available for building houses such as steep slopes and water bodies lead to less investment on average relative to the size of the existing housing stock leaving less scope for the supply response to attenuate the effects of a demand shock my estimates and simulations confirm that regulation and geographic constraints play critical and complementary roles in decreasing the responsiveness of investment to demand shocks which in turn amplifies house price volatility

econometric modelling of non ferrous metal prices abstract this article evaluates the significance of the empirical models and the distributional properties of prices in non ferrous metal spots and futures markets published in leading refereed economics and finance journals between 1980 and 2002 the survey focuses on econometric analyses of pricing and return models applied to exchange based spot and futures markets for the main industrially used non ferrous metals namely aluminium copper lead nickel tin and zinc published empirical research is evaluated in the light of the type of contract examined frequency of data used choice of both dependent and explanatory variables use of proxy variables type of model chosen economic hypotheses tested methods of estimation and calculation of ses for inference reported descriptive statistics use of diagnostic tests of auxiliary assumptions use of nested and non nested tests use of information criteria and empirical implications for non ferrous metals
