sticky prices and monetary policy evidence from disaggregated us data this paper disentangles fluctuations in disaggregated prices due to macroeconomic and sectoral conditions using a factor augmented vector autoregression estimated on a large data set on the basis of this estimation we establish eight facts 1 macroeconomic shocks explain only about 15 of sectoral inflation fluctuations 2 the persistence of sectoral inflation is driven by macroeconomic factors 3 while disaggregated prices respond quickly to sector specific shocks their responses to aggregate shocks are small on impact and larger thereafter 4 most prices respond with a significant delay to identified monetary policy shocks and show little evidence of a price puzzle contrary to existing studies based on traditional vars 5 categories in which consumer prices fall the most following a monetary policy shock tend to be those in which quantities consumed fall the least 6 the observed dispersion in the reaction of producer prices is relatively well explained by the degree of market power 7 prices in sectors with volatile idiosyncratic shocks react rapidly to aggregate monetary policy shocks 8 the sector specific components of prices and quantities move in opposite directions

heterogeneous response of disaggregate inflation to monetary policy regime change the role of price stickiness abstract this paper explores how a monetary regime change affects headline inflation via differential effects on various sectors in the economy using disaggregated cpi data for canada we find that the response to the adoption of inflation targeting it was quite heterogeneous across sectors while sticky price sectors experienced a notable change in inflation dynamics following it adoption little structural change was observed in flexible price sectors our analysis based on a common factor model suggests that the structural changes in the sticky price sectors are driven by a decline in their responses to common aggregate shocks including a monetary shock

price setting during low and high inflation evidence from mexico this paper provides new insight into the relationship between inflation and the setting of individual prices by examining a large data set of mexican consumer prices covering episodes of both low and high inflation when the annual rate of inflation is low below 10 15 the frequency of price changes comoves weakly with inflation because movements in the frequency of price decreases and increases partly offset each other in contrast the average magnitude of price changes correlates strongly with inflation because it is sensitive to movements in the relative shares of price increases and decreases when inflation rises beyond 10 15 few price decreases are observed and both the frequency and average magnitude are important determinants of inflation i show that a menu cost model with idiosyncratic technology shocks predicts the average frequency and magnitude of price changes well over a range of inflation similar to that experienced by mexico

contracts as a barrier to entry it is shown that an incumbent seller who faces a threat of entry into his or her market will sign long term contracts that prevent the entry of some lower cost producers even though they do not preclude entry completely moreover when a seller possesses superior information about the likelihood of entry it is shown that the length of the contract may act as a signal of the true probability of entry

why has u s inflation become harder to forecast we examine whether the u s rate of price inflation has become harder to forecast and to the extent that it has what changes in the inflation process have made it so the main finding is that the univariate inflation process is well described by an unobserved component trend cycle model with stochastic volatility or equivalently an integrated moving average process with time varying parameters this model explains a variety of recent univariate inflation forecasting puzzles and begins to explain some multivariate inflation forecasting puzzles as well

reconsidering the relationship between inflation and relative price variability it has long been popularly believed that the relationship between inflation and relative price variability rpv is positive and stable using disaggregated cpi data for the united states and japan however this study finds that the relationship is neither linear nor stable over time the overall relationship is approximately u shaped around a nonzero threshold inflation rate rpv therefore changes not with the inflation rate per se but with the deviation of inflation from the threshold inflation rate more importantly the relationship is by no means stable over time but instead varies significantly in a way that coincides with regime changes of inflation or monetary policy the relationship was positive during the period of high inflation of the 1970s and the early 1980s as has been documented by a number of previous studies whereas it takes a u shape profile during the great moderation the results are robust to the use of core inflation which excludes the traditionally volatile prices of food and energy this paper then presents a modified version of the calvo type sticky price model to describe the observed empirical regularities simulation experiments show that the modified calvo model fits the data well and that the underlying relationship hinges upon the degree of price rigidity which is systematically related to inflation regime for countries and periods with low inflation rates the relationship takes a u shape as price adjustment is more sticky in a high inflation environment when price setting becomes more flexible the u shaped profile vanishes

optimal monetary policy responses to relative price changes abstract an optimizing model with a flexible price sector and a sticky price sector is presented to analyze the effects of relative price changes on inflation fluctuations the relative price of the flexible price good represents a shift parameter of the new keynesian phillips curve the optimal monetary policy is to target sticky price inflation rather than a broad inflation measure although stabilizing the relative price around its efficient value is one of the appropriate goals of the central bank stabilizing sticky price inflation is sufficient for achieving this goal an optimal monetary policy for a small open economy is also discussed

international corporate entrepreneurship and firm performance the moderating effect of international environmental hostility abstract globalization of the world economy has encouraged u s companies to leverage their resources and skills by expanding into existing or new foreign markets u s companies have also acquired new capabilities by locating important functional activities overseas and joining with foreign partners in new markets through alliances and joint ventures these opportunities however are tempered by the constraints imposed by the competitive forces that exist in international environments aggressive government intervention technological changes and fierce local rivalries all contribute to hostile international environments for u s firms global expansion success in global business operations requires resourcefulness and entrepreneurial risk taking the activities of u s companies in foreign markets therefore provide a unique opportunity to examine the effects of international corporate entrepreneurship ice efforts on company performance ice is defined as the sum of a company s efforts aimed at innovation proactiveness and risk taking these efforts offer an important means of revitalizing and renewing established companies and improving their performance few studies have empirically examined the effects of ice activities on companies financial performance this study used data from 98 u s companies to 1 determine the impact of ice efforts on firm performance and 2 explore the moderating effect that the perceived hostility of the international environment has on the relationship between ice and company performance the results showed that ice was positively associated with a firm s overall profitability and growth as well as its foreign profitability and growth those firms that aggressively pursued ice in international environments with higher levels of hostility had higher return on assets roa but did not achieve significantly higher levels of growth however as hostility in the international environment continued to intensify roa rose and then fell as companies increased their ice activities thus there was a point of diminishing returns to a company s aggressive pursuit of ice under excessive environmental hostility the results highlight both the rewards and risks of pursuing ice companies benefit from ice activities by achieving higher overall performance as well as foreign profits and growth in revenue however the aggressive pursuit of ice does not always guarantee superior performance our results show that the payoff from ice is moderated by executives perceptions of the hostility of their firm s international business environment our findings highlight the importance of ice for organizational success both overall and in foreign markets yet the results compellingly suggest that there are upper limits to the potential gains a firm achieves from its aggressive pursuit of ice when the international environment in which it competes is hostile

disaggregate evidence on the persistence of consumer price inflation this paper uses disaggregate inflation data spanning all of consumption to examine i the persistence of disaggregate inflation relative to aggregate inflation ii the distribution of persistence across consumption sectors and iii whether persistence has changed assuming mean inflation to be unchanged disaggregate persistence inflation is consistently below aggregate persistence taking into account an early 1990s shift in mean inflation identified by break tests yields much lower estimates of both aggregate and disaggregate persistence for 1984 2002 but with the mean break average disaggregate persistence is actually as great as aggregate inflation persistence a factor model provides a natural framework for interpreting the relationship between aggregate and disaggregate persistence copyright 2006 john wiley sons ltd

platform investments and volatile exchange rates direct investment in the u s by japanese electronic companies this study examines the effects of previous entry on the subsequent decisions of japanese electronics companies to invest in the united states by gathering data at the firm level the empirical analysis provides a fine grain sorting out of firm and industry effects on foreign direct investment decisions the findings show that investment behavior is highly heterogeneous across firms and reflects their individual technological capabilities and their history of previous investments in the united states real exchange rate levels are also important the results suggest that initial investments serve as platforms for subsequent entry with the timing of entry triggered by movements in real exchange rates copyright 1996 by mit press

firm specific strategic advantages and foreign direct investment behavior of firms the case of japanese semiconductor firms we examine the effects of firm specific strategic advantages on the fdi behavior of japanese semiconductor firms we investigate the strategic advantages necessary for undertaking fdi in this industry and show that these advantages are systematically associated with the variation in fdi behavior we identify technological innovation a broad product line and vertical linkages with down stream businesses as sources of such strategic advantages we also show that size of the firm influences its decision to go international

interpreting the macroeconomic time series facts the effects of monetary policy existing theory and evidence on the effects of monetary policy are reviewed substantial room for disagreement among economists remains new evidence based on multivariate time series studies of several countries is presented while certain patterns in the data consistent with effective monetary policy are strikingly similar across countries others particularly the tendency of interest rate increases to predict high inflation are harder to reconcile with effective monetary policy

competition or predation consumer coordination strategic pricing and price floors in network markets although network effects can make predation more likely to succeed we find that the leading anti predation rules may lower or raise efficiency and consumer welfare in network markets we find that a the extensive debates about the correct measure of cost on which to base price floors are unlikely to be productive b the ordover willig rule that is widely thought to be correct in theory but difficult to apply in practice is in fact incorrect in theory and c efficient price floors would have to depend on consumer expectations and coordination processes that are unlikely to be observable in practice

an equilibrium selection theory of monopolization we develop a duopoly model in which firms compete for the market e g investing in process innovation or product development as well as in the market e g setting quantities or prices competition for the market generates multiple equilibria that differ in the firms investment levels relative size and profitability we show that monopolization that affects competition in the market can act as an equilibrium selection device in competition for the market in particular it eliminates equilibria that are undesirable for the monopolizing firm while not generating new equilibria this result complicates the task of determining whether a firm s dominance in a given market is the result of fair competition or unlawful monopolization we discuss a number of implications for antitrust policy and litigation and illustrate these by means of two well known antitrust cases

dynamic analysis of discontinuous best response with innovation abstract starting from the static analysis in eckert et al 2017 we study a cournot duopoly where firms can decide to incur fixed costs in activities that improve their competitiveness i e product development or process innovation innovation costs generate discontinuities in the firms quantity best response functions and in turn a variety of equilibrium configurations including multiple equilibria we provide a dynamic global analysis of the equilibria and show the way in which firms initial expectations regarding the rivals level of output are crucial in defining the configuration of the long run equilibrium

choice of foreign market entry mode impact of ownership location and internalization factors firms interested in servicing foreign markets face a difficult decision with regards to the choice of an entry mode the options available to a firm include exporting licensing joint venture and sole venture several factors that determine the choice of a specific foreign market entry mode have been identified in previous literature these factors can be classified into three categories ownership advantages of a firm location advantages of a market and internalization advantages of integrating transactions this study examines the independent and joint influences of these factors on the choice of an entry mode multinomial logistic regression model is employed to test the hypothesized effects

on the detection of collusion and predation abstract this lecture not only shows how game theory can contribute to the detection of collusion and predation but also how experts for the defense can use game theoretic arguments to make such detection difficult a few important european anti trust cases are discussed to illustrate

can aggregation explain the persistence of inflation abstract an aggregation exercise is proposed that aims at investigating whether the fast average adjustments of the disaggregate inflation series of the euro area cpi is coherent with the slow adjustment of euro area aggregate inflation estimating a dynamic factor model for 404 inflation sub indices of the euro area cpi allows to decompose the dynamics of inflation sub indices into a part due to a common macroeconomic shock and to sector specific idiosyncratic shocks although idiosyncratic shocks dominate the variance of sectoral prices one common factor appears to be the main driver of aggregate dynamics in addition the heterogenous propagation of this common shock across sectoral inflation rates and in particular its slow propagation to inflation rates of services generates the persistence of aggregate inflation we conclude that the aggregation mechanism explains a significant amount of aggregate inflation persistence

sectoral and aggregate inflation dynamics in the euro area this paper synthesises the implications of recent statistical evidence regarding inflation persistence in the euro area for aggregate data the degree of inflation persistence appears to be very high for sample periods spanning multiple decades but falls dramatically once we allow for time variation in the mean level of inflation furthermore the timing of these breaks in mean generally coincides with observed shifts in the monetary policy regime finally sectoral inflation series exhibit much less persistence than aggregate inflation mainly because of the influence of transitory sector specific shocks jel e31 c22 c43

the perception and measurement of transaction costs the chapter discusses various explanations of how transaction cost minimising corporate configurations come about it contrasts darwinian with rational explanations finding both unsatisfactory what matters rather than computation of fully recognised transaction costs are managerial perceptions of transaction costs these perceptions are not expressed in numbers but in language this is related to arguments derived from bounded rationality and from transaction cost economics the chapter argues that issues of managerial perception must become central to analysis existing academic traditions which accord primacy to perception and to language are drawn upon and argued to be of great relevance to future work

investigating inflation persistence across monetary regimes under inflation targeting estimates of the indexation parameter in hybrid new keynesian phillips curves are either equal to zero or very low in the united kingdom canada sweden and new zealand analogous results hold for the euro area under the european monetary union and for switzerland under the new monetary regime under stable regimes with clearly defined nominal anchors inflation appears to be purely forward looking these results question the notion that the intrinsic inflation persistence found in post wwii u s data is structural in the sense of lucas carnegie rochester conference series on public policy 1 1976 19 46 and suggest that hardwiring inflation persistence in macroeconomic models is potentially misleading

cost raising strategies advantage rivals by raising their costs in this paper we show that strategies designed to raise rivals costs have a number of advantages over predatory pricing they are credible do not necessarily require the victim to exit and do not necessarily require the existence of classical market power the paper sets up a general model proves a number of general results and then applies the model to specific strategies involving overbuying inputs and vertical integration

an antitrust analysis of bundled loyalty discounts abstract consider a monopolist in one market that faces competition in a second market bundled loyalty discounts in which customers receive a price break on the monopoly good in exchange for making all purchases from the monopolist have ambiguous welfare effects such discounts should not always be treated as a form of predatory pricing in some settings they act as tie in sales existing tests for whether such discounts violate competition laws do not track changes in consumer surplus or total surplus we apply a new test to an illustrative example based on smithkline that assumes the tied market has homogeneous goods if the tied market is characterized by hotelling competition bundling by the monopolist causes the rival firm to reduce its price in numerical examples we find that this can deter entry or induce exit

capital as a commitment strategic investment to deter mobility abstract this paper analyzes how an early entrant in a market can exploit its head start by strategic investment the analysis is based on spence s paper investment strategy and growth in a new market bell j econ 10 1979 1 19 we frist study the investment game in the no discounting case which embodies the key features of mobility deterrence we establish the existence of a set of perfect equilibria and suggest that one particular equilibrium is most reasonable this equilibrium also valid with discounting involves the follower firm being forever deterred from investing to its steady state reaction curve in contrast to spence s proposed solution

a new theory of equilibrium selection for games with complete information abstract in an earlier paper the author proposed a new theory of equilibrium selection for games with complete information in this paper he proposes an extension of this theory to games with incomplete information a mathematical model is suggested for measuring the strength of the incentives that each type of any player has to use any particular strategy in the case he represents this player in the game then these incentive measures are used for estimating the theoretical probability for any given nash equilibrium to emerge as the outcome of the game the solution of the game is defined as the nash equilibrium with the highest theoretical realization probability when this equilibrium is unique the problems posed by non uniqueness are also discussed journal of economic literature classification numbers c72

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

tying foreclosure and exclusion in recent years the leverage theory of tied good sales has faced heavy and influential criticism in an important sense though the models used by its critics are actually incapable of addressing the leverage theory s central concerns here the author reconsiders the leverage hypothesis and argues that tying can indeed serve as a mechanism for leveraging market power the mechanism through which this leverage occurs its profitability and its welfare implications are discussed in detail copyright 1990 by american economic association

sectoral price data and models of price setting in the median sector 100 percent of the long run response of the sectoral price index to a sector specific shock occurs in the month of the shock the standard calvo model and the standard sticky information model can match this finding only under extreme assumptions concerning the profit maximizing price the rational inattention model of mackowiak and wiederholt 2009a optimal sticky prices under rational inattention american economic review 99 769 803 can match this finding without an extreme assumption concerning the profit maximizing price furthermore there is little variation across sectors in the speed of response of sectoral price indexes to sector specific shocks the rational inattention model matches this finding while the calvo model predicts too much cross sectional variation

exploiting the conditional density in estimating the term structure an application to the cox ingersoll and ross model we propose an empirical method that utilizes the conditional density of the state variables to estimate and test a term structure model with known price formulae using data on both discount and coupon bonds the method is applied to an extension of a two factor model due to cox ingersoll and ross 1985 cir our results show that estimates based on only bills imply unreasonably large price errors for longer maturities we reject the original cir model using a likelihood ratio test and conclude that the extended cir model also fails to provide a good description of the treasury market

endogenous nominal rigidities and monetary policy monetary policy analysis with exogenously given nominal rigidities is subject to lucas critique if the degree of them varies over policy regimes as recent empirical studies point out in a calvo style sticky price model we endogenize nominal rigidities and examine its implications for monetary policy while previous studies stress that the frequency of price adjustment changes with steady state inflation we focus on how this frequency varies in response to changes in the taylor rule in the same steady state we find that a more aggressive policy response to inflation makes firms less likely to reset their prices resulting in a flat slope of the new keynesian phillips curve as observed in the post 1982 u s economy and a small variance of shocks to the curve as in the great moderation we also find that an aggressive policy response to inflation can stabilize both inflation and the output gap by exploiting the feedback effect of the policy stance on firms price setting taking into account this effect is thus crucial to the policy conduct further we show that an endogenous inflation weight of the social welfare loss function is critical to policy evaluation since this weight changes significantly with the frequency of price adjustment jel classification e31 e32 e52

trial and settlement a study of high low agreements this paper presents the first systematic theoretical and empirical study of high low agreements in civil litigation a high low agreement is a private contract that if signed by litigants before the conclusion of a trial constrains the future damages payment to lie between a minimum and a maximum amount whereas the existing literature describes litigation as a choice between trial and settlement our examination of high low agreements a relatively new phenomenon in civil litigation introduces partial or incomplete settlements in our theoretical model trial is both costly and risky when litigants have divergent subjective beliefs and are mutually optimistic about their trial prospects cases may fail to settle in these cases high low agreements can be in the litigants mutual interest because they limit the risk of outlier damages awards while still allowing for an optimal degree of speculation using unique insurance claims data from a national insurance company we describe the features of these agreements and empirically investigate the factors that may influence whether litigants discuss or enter into high low agreements our empirical findings are consistent with the predictions of the theoretical model we also explore extensions and alternative explanations for high low agreements including their use to mitigate excessive offsetting trial expenditures

imperfect credibility and inflation persistence in this paper we formulate a dynamic general equilibrium model with staggered nominal contracts in which households and rms use optimal ltering to disentangle persistent and transitory shifts in the monetary policy rule the calibrated model accounts quite well for the dynamics of output and insation during the volcker disinsation and implies a sacri ce ratio very close to the estimated value our approach indicates that insation persistence and substantial costs of disinsation can be generated in an optimizing agent framework without relaxing the assumption of rational expectations or relying on arbitrary modi cations to the aggregate supply relation jel classi cation e31 e32 e52

foreign direct investment by japanese electronics firms in the united states and canada modelling the timing of entry this paper examines the relationship between attributes of japanese electronics firms and the sequence of their investments in the u s and canada it is argued that a useful way to model foreign direct investment fdi decisions is to recognize explicitly the uncertainties involved in them a probabilistic model of fdi is specified the following hypotheses are incorporated in the model 1 the higher the risk adjusted expected net benefits from foreign direct investment ceteris paribus the higher the probability of making an investment at any particular moment and thus the probability of investing earlier 2 risk adjusted expected net benefits from fdi by a firm are a function of its possession of certain types of intangible transportable assets 3 the uncertainties involved with fdi may be reduced with the passage of time and with increased experience with foreign operations 4 parent company attributes that facilitate market intelligence capabilities permit early recognition of investment opportunities and 5 timing of entry may reflect strategic considerations such as responding to growing foreign market opportunities the need to ensure market access and the presence of opportunities to obtain abnormal profits due to market concentration the models are estimated using cox s proportional hazards regression model results generally confirm the hypotheses that size and financial capabilities as well as possession of some knowledge based firm specific strategic assets are significantly related to early fdi they also confirm that timing of entry is affected by market opportunities and in some cases by the need to ensure market access we did not find evidence in this sector that differences in market concentration significantly affected the timing of fdi analyses are also provided of inter period changes in the importance of different types of intangible assets in explaining earlier fdi as well as changes that reflect differences in host country environments

competing for capital the diffusion of bilateral investment treaties 1960 2000 over the past forty five years bilateral investment treaties bits have become the most important international legal mechanism for the encouragement and governance of foreign direct investment the proliferation of bits during the past two decades in particular has been phenomenal these intergovernmental treaties typically grant extensive rights to foreign investors including protection of contractual rights and the right to international arbitration in the event of an investment dispute how can we explain the widespread adoption of bits we argue that the spread of bits is driven by international competition among potential host countries typically developing countries for foreign direct investment we propose a set of hypotheses that derive from such an explanation and develop a set of empirical tests that rely on network measures of economic competition as well as more indirect evidence of competitive pressures on the host to sign bits the evidence suggests that potential hosts are more likely to sign bits when their competitors have done so we find some evidence that coercion and learning play a role but less support for cultural explanations based on emulation our main finding is that the diffusion of bits is associated with competitive economic pressures among developing countries to capture a share of foreign investment we are agnostic at this point about the benefits of this competition for development for useful comments on earlier drafts of this article we thank bill bernhard bear braumoeller frank dobbin robert franzese jeffry frieden geoffrey garrett tom ginsburg jude hays lisa martin bob pahre mark ramsayer steven ratner susan rose ackerman and john sides for research assistance we thank elizabeth burden raechel groom and alexander noonan

japanese firms and the decision to invest abroad business groups and regional core networks the determinants of the decision by japanese firms to set up manufacturing plants in southeast asia europe and north america are analyzed using micro data on the behavior of firms in the electronics industry while firm specific intangible assets based on r d and marketing efforts are positively related to the decision to invest in europe and north america investment in southeast asia is mainly related to human resources and driven by interfirm ties within horizontal and vertical business groups the empirical results suggest that membership of horizontal keiretsu relaxes liquidity constraints while the manufacturing networks of horizontal and vertical keiretsu in southeast asia facilitate the establishment of manufacturing plants by member firms copyright 1996 by mit press

vertical keiretsu and international market entry the case of the japanese automobile ancillary industry this study investigated whether small japanese automobile ancillary firms followed the major japanese automakers in setting up production facilities in the united states based on dunning s eclectic theory of foreign direct investment and resource dependence theory hypotheses were generated to explain the determinants of foreign investment of japanese suppliers it was hypothesized that mutual dependencies between the major japanese automobile firms and their suppliers firm specific ownership advantages profitability and keiretsu affiliation influenced the foreign direct investment of the first tier automobile ancillary firms into the united states data on the entire population of 446 japanese automobile ancillary manufacturers were obtained from archival sources logistical regression analyses indicated that keiretsu affiliation previous international experience small size lower dependence of supplier firms on the automobile assembly firm and higher dependence of core firms on affiliate firms all contributed to this foreign direct investment

has monetary policy become more effective we investigate the implications of changes in the structure of the u s economy for monetary policy effectiveness estimating a vector autoregression over the pre and post 1980 periods we provide evidence of a reduced effect of monetary policy shocks in the latter period we estimate a structural model that replicates well the economy s response in both periods and perform counterfactual experiments to determine the source of the change in the monetary transmission mechanism and in the economy s volatility we find that by responding more strongly to inflation expectations monetary policy has stabilized the economy more effectively in the post 1980 period

naked exclusion comment the ability of an incumbent firm to deter entry by writing exclusionary contracts with customers has been a subject of contention in the antitrust literature the courts concern with such exclusionary contracts has been challenged by those who argue that an incumbent faced with buyers whose interest is to promote entry and competition would have to pay buyers more for the inclusion of exclusionary provisions than it could possibly gain from exclusion in a provocative article eric b rasmusen et al 1991 henceforth rrw have argued that an incumbent may in fact be able to exclude rivals profitably using such contractual provisions because it can exploit buyers lack of coordination in essence if buyers expect other buyers to sign such provisions then they may see little reason not to do so themselves the rrw argument is potentially an important one because most alleged instances of entry deterrence through exclusionary contracts with customers occur in situations with multiple buyers unfortunately however rrw s two main results contain errors in this note we reconsider the rrw model providing correct characterizations of the likelihood and cost of exclusion for an incumbent firm our results indicate that while the intuition suggested by rrw is valid the equilibrium likelihood and cost of exclusion differ from what rrw derive moreover our analysis illuminates some further aspects of exclusionary contracting with multiple buyers among these issues we focus on how an incumbent can use discriminatory offers to exploit the externalities that exist among buyers in the provision of competition in section i we review the basic assumptions of the rrw model in sections ii and iii we then consider in turn the cases of simultaneous and sequential offers studied by rrw for the simultaneous model we distinguish between settings in which the incumbent can and cannot discriminate in its offers to different buyers this distinction is the source of the problem in rrw s analysis their simultaneous offer model assumes no discrimination but the proof of their proposition 2 assumes at times that discrimination is feasible we show that absent the ability to discriminate the incumbent can exclude profitably only when buyers fail to coordinate on their most preferred continuation equilibrium in contrast we show that when discrimination is possible the incumbent need not rely on a lack of buyer coordination to segal department of economics landau building stanford university stanford ca 94305 e mail ilya segal stanford edu whinston department of economics northwestern university 2003 sheridan road evanston il 60208 e mail mwhinston nwu edu we thank eric rasmusen john wiley and participants in the berkeley stanford iofest the university of copenhagen vertical restraints conference and a seminar at the antitrust division of the u s department of justice for helpful comments we thank federico echenique for excellent research assistance 1 for example a recent department of justice investigation concerned the use of exclusive contracts by the leading provider of computerized ticketing services ticketmaster most major cities have several large concert sports venues in many cities ticketmaster has exclusive contracts with a very large share of these venues 2 the other leading response to the argument that contracts with buyers cannot be a profitable method of exclusion is given in philippe aghion and patrick bolton 1987 section i one factor limiting the applicability of the aghion and bolton theory however is that it involves partial exclusion the contracts signed are not fully exclusionary they involve finite stipulated damages and the profitability of the strategy arises from extracting rents from an entrant when entry occurs indeed in the aghion and bolton model contracts that fully exclude offer no benefits over writing no contract at all in section iii of their paper aghion and bolton also discuss a two buyer version of their model in which externalities arise across buyers in contrast to the analysis here and in rrw they allow the incumbent to make an offer to a buyer i that is conditional on the acceptance decision of the other buyer 3 r innes and r j sexton 1994 also discuss the use of discriminatory offers in the context of a model in which buyers can form coalitions with the entrant

capacity investment preemption and commitment in an infinite horizon model the commitment value of capacity is analyzed in an infinite horizon duopoly model the paper focuses on the role of alternative behavioral assumptions about the ability of firms to commit to investment paths each firm s investment strategy in a feedback nash equilibrium is shown to be a decreasing function of its rival s current capacity this creates an incentive for a firm to expand its capacity to preempt subsequent rival investment in a precommitment equilibrium there are no incentives to invest preemptively as a consequence steady state capacity levels are greater in a feedback nash equilibrium than in a precommitment equilibrium copyright 1987 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

monetary non neutrality in a multisector menu cost model empirical evidence suggests that as much as one third of the u s business cycle is due to nominal shocks we calibrate a multisector menu cost model using new evidence on the cross sectional distribution of the frequency and size of price changes in the u s economy we augment the model to incorporate intermediate inputs we show that the introduction of heterogeneity in the frequency of price change triples the degree of monetary non neutrality generated by the model we furthermore show that the introduction of intermediate inputs raises the degree of monetary non neutrality by another factor of three without adversely affecting the model s ability to match the large average size of price changes a single sector model with a frequency of price change equal to the median rather than the mean generates monetary non neutrality similar to that in our multisector model our multisector model with intermediate inputs generates variation in real output in response to calibrated aggregate nominal shocks that can account for roughly 23 of the u s business cycle

comparative business failures of foreign controlled firms in the united states we explore the comparative business failures of foreign owned or controlled firms and domestically owned firms original data are collected regarding foreign controlled firms in the u s that filed for bankruptcy protection were involuntarily liquidated or ceased operations mainly due to poor financial performance during the 1978 1988 period our results show that foreign controlled firms fail less often than domestically owned firms the patterns of foreign controlled business failures and the impacts of entry modes ownership types and national culture on the failures of foreign controlled firms are also examined

do measures of monetary policy in a var make sense a reply to christopher a sims using the estimated var system one can trace out how monetary policy innovations affect the economy as john cochrane 1996 p 1 notes this literature has at last produced impulse response functions that capture common views about monetary policy for example in finding that a positive innovation to monetary policy is followed by increases in output prices and money and by a decline in the short term nominal interest rate in addition despite ongoing debates about precisely how the policy innovation should be identified the estimated responses of key macroeconomic variables to a policy shock are reasonably similar across a variety of studies and suggest that monetary policy shocks can have significant and persistent real effects

term structure views of monetary policy under alternative models of agent expectations abstract term structure models and many descriptions of the transmission of monetary policy rest on the empirical relevance of the expectations hypothesis small differences in the perceived policy reaction function in var models of agent expectations strongly influence the relevance in the transmission mechanism of the expected short rate component of bond yields mean reverting or difference stationary characterizations of interest rates require large and volatile term premiums to match the observable term structure however short rate descriptions that capture shifting perceptions of long horizon inflation evident in survey data support a more substantial term structure role for short rate expectations

the role of two frictions in geographic price dispersion when market friction meets nominal rigidity this paper empirically investigates and theoretically derives the implications of two frictions market friction and nominal rigidity on the dynamic properties of intra national relative prices with an emphasis on the interaction of the two frictions by analyzing a panel of retail prices of 45 products for 48 u s cities over the period 1985 2009 we make two major arguments first the effect of each type of friction on the dynamics of intercity price gaps is quite different while market frictions arising from physical distance and transportation costs have a positive impact on volatility and persistence of intercity price dispersion nominal rigidities have a positive impact on persistence but a negative impact on volatility this empirical evidence is different from what is predicted by standard theoretical cross country models based on price stickiness second complementarities exist between market frictions and nominal rigidities such that the marginal effect of a market friction dwindles as nominal rigidities increase we provide an alternative theoretical explanation for this finding by extending the state dependent pricing sdp model of dotsey et al 1999 and show that our two city model with nominal rigidity and market frictions can successfully explain the salient features of the dynamic behavior of intercity price differences that have not been captured in previous analysis
