currency competition a partial vindication of hayek abstract this paper establishes the existence of equilibria for environments in which outside money is issued competitively such equilibria are typically believed not to exist because of a classic overissue problem if money is valued in equilibrium an issuer produces money until its value is driven to zero by backward induction money cannot have value in the first place this paper shows that overissuance is not a problem if agents believe that if an issuer produces more than some threshold number of notes then only those notes issued up to the threshold will be valued additional notes will be worthless this result is very general applying to any monetary economy in which equilibria with and without valued money exist if the money supply is finite the paper also compares the allocation achieved by a monopolist to that achieved with competitive issuance in both a search and an overlapping generations environment the results depend on the environment considered but two general conclusions arise first it is ambiguous whether competitive issuers can achieve a more desirable allocation than a monopolist second with competitive issuance a licensing agency can always improve on pure laissez faire and achieve the efficient allocation in the long run

safe assets as commodity money this paper presents a model in which safe assets are systemic because they are the medium of exchange in risky assets it connects the literature from banking and finance on safe assets to the monetary literature on alternative monetary systems involving commodity money interest bearing money and private money creation because safe assets have intrinsic value changes in their supply lead to changes in market efficiency additionally because safe assets are costly to produce there is overproduction of safe assets relative to the social optimum when the model is calibrated to plausible liquidity premiums the resulting inefficiencies are not large

private versus public money i show that the nature of agents production determines whether they should issue money i use a matching model with no commitment and no enforcement some agents can produce goods whereas others are unproductive all agents can produce at a cost a distinguishable intrinsically useless but durable good notes productive agents produce red notes whereas unproductive agents produce green notes i find that green notes are the most efficient means of exchange as they implement more allocations than red notes and at a lower cost therefore unproductive agents should issue money i associate unproductive agents to agents producing public goods

anonymous markets and monetary trading abstract we study infinite horizon monetary economies characterized by trading frictions that originate from random pairwise meetings and commitment and enforcement limitations we prove that introducing occasional trade in centralized markets opens the door to an informal enforcement scheme that sustains a non monetary efficient allocation all is required is that trading partners be patient and their actions be observable we then present a matching environment in which trade may occur in large markets and yet agents trading paths cross at most once this allows the construction of models in which infinitely lived agents trade in competitive markets where money plays an essential role

private fiat money with many suppliers a dynamic rational expectations model of money is used to investigate whether a nash equilibrium of many firms each supplying its own brand name currency will optimally deflate their currencies in friedman s 1969 sense the optimal deflation does arise under an open loop dynamic structure but the equilibrium breaks down under a more realistic feedback control structure

vertical integration market foreclosure and consumer welfare in the cable television industry i examine the effects of vertical integration between programming and distribution in the cable television industry i assess the effects of ownership structure on program offerings prices and subscriptions and i compare consumer welfare across integrated and unintegrated markets the results of this analysis suggest two general conclusions first integrated operators tend to exclude rival program services suggesting that certain program services cannot gain access to the distribution networks of vertically integrated cable system operators second vertical integration does not harm and may actually benefit consumers because of the associated efficiency gains

on the launching of a new currency this paper studies the appropriate way of launching a new fiat currency within a dual currency search theoretic framework we demonstrate that legal tender laws may not be sufficient to guarantee the acceptability of the new currency and that the old currency may continue to circulate if the enforcement power of legal tender laws is weak and the fraction of individuals endowed with the new currency is too low the possibility of converting the old currency into the new one can ease the transition to the new currency only if it is combined with strict legal tender laws finally a network externality may generate inefficiencies in the decision to switch to the new currency

a new index of vertical integration some estimates for uk manufacturing abstract this paper proposes a new method for measuring the degree of vertical integration within a firm or industry it is based on the magnitude of intra firm flows of output across industries relative to the magnitude of market transactions while data on intra firm flows are often sketchy or non existent we show how they may be imputed indirectly from standard input output tables and information on market shares of firms across industries estimates are reported and analysed for uk manufacturing in 1986 for 79 industries and their leading firms thereby providing the first known comprehensive picture of vertical integration in the united kingdom

assets and liabilities and scottish independence scottish independence implies an economic future that is different from remaining in the united kingdom the economic debate largely comes down to whether this would leave scots better or worse off by most measures scotland s current economic standing is very similar to that of an average uk region output per head income and unemployment are almost all exactly the same as the average uk region this is not surprising given the economic and social integration and shared institutions and is consistent with the idea of conditional convergence this suggests that after controlling for differences in institutions and other characteristics so called initial conditions countries tend to converge to similar levels of income 1 however if scotland becomes an independent nation some of the shared uk assets liabilities and institutions would need to be divided up this would change the initial conditions for scotland and the rest of the uk and therefore we would be likely to see a different economic future for both regions see barro and sala i martin 1991

banking a new monetarist approach we develop a model where i banks take deposits and make investments ii their liabilities facilitate third party transactions other models have i or ii not both although we argue they are intimately connected we show that they both emerge from limited commitment we describe an environment characterize desirable allocations and interpret the outcomes as banking arrangements banks are essential without them the set of feasible allocations is inferior as a technical contribution we characterize dynamically optimal credit allocations with frictions show they involve backloading and analyse how this interacts with banking we also confront the theory with economic history copyright 2013 oxford university press

a search model of money and circulating private debt with applications to monetary policy a search theoretic model is used to examine the coexistence of money and circulating private debt money is still valued even though there coexists credit which circulates among agents and dominates in the rate of return when there coexist multiple equilibria the equilibrium with credit pareto dominates the one without credit if money supply is not extremely plentiful this article also provides some predictions about the effects of monetary policies a policy of open market operations whereby government discounts less for second hand debt decreases the value of money credit and interest rate prevailing in the market this policy can also improve welfare by making credit trade feasible when the only equilibrium entails no credit without intervention

vertical organization of production and firm growth this paper empirically explores if different vertical organizational forms i e vertical integration versus dis integration give rise to unlike growth behaviors within the same industry an econometric analysis is conducted in a sample of around 500 italian machine tool mt builders for the period 1998 2007 implementing instrumental variables to control for the endogeneity of the organizational form in the relation ceteris paribus vertically integrated firms result to be characterized by a less dispersed distribution of growth rates than their dis integrated counterparts several concurring factors such as adjustment costs organizational slacks and a better management of fluctuations in the markets of intermediate and final products may explain the more a stablea growth profile of vertically integrated firms by means of analyzing how different organizational forms map into the distribution of output growth rates this work provides insight into the firm dynamics in a mature industry in which both vertically integrated and dis integrated firms coexist

a search theoretic approach to monetary economics the essential function of money is its role as a medium of exchange the authors formalize this idea using a search theoretic equilibrium model of the exchange process that captures the double coincidence of wants problem with pure barter one advantage of the framework described here is that it is very tractable the authors also show that the model can be used to addre ss some substantive issues in monetary economics including the potenti al welfare enhancing role of money the interaction between specializat ion and monetary exchange and the possibility of equilibria with multip le fiat currencies copyright 1993 by american economic association

technical efficiency unions and decentralized labor contracts abstract this paper explores the link between the presence of unions in the workplace the adoption of decentralized labor agreements and technical efficiency using a large sample of italian manufacturing firms we apply the data envelopment analysis and its robust version based on bootstrap theory to get reliable estimates of technical efficiency at the firm level in a standard first stage we devote particular attention to the specific technology adopted by distinguishing 20 different sector frontiers as well as to the presence of outliers the obtained efficiency scores are analyzed in a second stage applying a truncated regression model estimated via maximum likelihood following the simar and wilson 2007 2011 methodology our results highlight that the presence of workplace unionization decreases the level of technical efficiency while aspects limiting the unions power such as a strong exposure to international markets high debt levels or the prevalence of flexible assets partially reduce the negative effect however when firms adopt decentralized labor contracts agreements the effect on efficiency is positive and partially compensates the negative unions effect

information learning and the stability of fiat money abstract we analyze the stability of monetary regimes in an economy where fiat money is endogenously created by the government information about its value is imperfect and learning is decentralized we show that monetary stability depends crucially on the speed of information transmission in the economy our model generates a dynamic on the acceptability of fiat money that resembles historical accounts of the rise and eventual collapse of overissued paper money it also provides an explanation of the fact that despite its obvious advantages the widespread use of fiat money is only a recent development

vertical integration and firm boundaries the evidence since ronald h coase s 1937 seminal paper a rich set of theories has been developed that deal with firm boundaries in vertical or input output structures in the last twenty five years empirical evidence that can shed light on those theories also has been accumulating we review the findings of empirical studies that have addressed two main interrelated questions first what types of transactions are best brought within the firm and second what are the consequences of vertical integration decisions for economic outcomes such as prices quantities investment and profits throughout we highlight areas of potential cross fertilization and promising areas for future work

inside and outside money as alternative media of exchange we study a random matching model of money in which a subset of people called bankers have known histories and the rest called nonbankers have unknown histories earlier we showed that if there are no outside assets then an optimal arrangement has bankers issuing objects banknotes that are used in trades involving nonbankers here the same model is used to compare such exclusive use of inside money to the exclusive use of outside money we show that the set of implementable outcomes using outside money is a strict subset of the set using inside money

efficiency and vertical integration the case of mine mouth electric generating plants this paper tests four propositions regarding the efficiency of vertical arrangements 1 vertically integrated and nonintegrated firms allocate inputs with efficiency and 2 achieve equal technical efficiency 3 upstream transaction specific investments provide monopsony power and 4 monopsony behavior does not differ by vertical arrangement a behavioral cost function for mine mouth generating plants is estimated the findings include significant differences in the allocative efficiency of integrated versus nonintegrated plants and increased technical efficiency for vertically integrated plants transaction specific investments in mines provide monopsony power nonintegrated plants exercise this power while integrated plants do not copyright 1991 by blackwell publishing ltd

money and credit redux do we need both money and credit in models with explicit roles for payment instruments we show the answer is no if credit is easy money is useless if credit is tight money can be essential but then credit is irrelevant and changes in debt limits are neutral real balances respond endogenously to leave total liquidity constant this is true for exogenous or endogenous policy and debt limits secured or unsecured credit and fairly general preferences and pricing mechanisms while we also show how to overturn some results the benchmark model suggests credit conditions matter less than some people think

a model of banknote discounts abstract prior to 1863 state chartered banks in the united states issued notes dollar denominated promises to pay specie to the bearer on demand although these notes circulated at par locally they usually were quoted at a discount outside the local area these discounts varied by both the location of the bank and the location where the discount was being quoted further these discounts were asymmetric across locations meaning that the discounts quoted in location a on the notes of banks in location b generally differed from the discounts quoted in location b on the notes of banks in location a also discounts generally increased when banks suspended payments on their notes in this paper we construct a random matching model to qualitatively match these facts about banknote discounts to attempt to account for locational differences the model has agents that come from two distinct locations each location also has bankers that can issue notes banknotes are accepted in exchange because banks are required to produce when a banknote is presented for redemption and their past actions are public information overall the model delivers predictions consistent with the behavior of discounts

vertical integration and efficiency an application to the italian machine tool industry this paper analyzes the relationship between firm efficiency and vertical integration in the italian machine tool mt industry the link may really be the result of a two way causality the effect may run from productive efficiency to the type of vertical organization i e vertical integration or outsourcing as a self selection mechanism or an effect from the organizational mode to the firm s performance may also be at work this relationship is empirically investigated in a novel panel dataset comprising about 500 italian mt builders implementing two equations and instrumental variables for the two directions of causality the evidence clearly indicates the self selection mechanism of the most efficient firms in vertically integrated structures while an effect from the organizational mode to the firm s efficiency is not supported

a model in which monetary policy is about money abstract optimal monetary policy is studied in a model with i heterogeneity in the degree to which different people are monitored have publicly known histories ii idiosyncratic shocks that give rise to heterogeneity in earning and spending realizations and iii central bank intervention in a market in claims or credit in which the participants are those who are heavily monitored a special case of the model has everyone perfectly monitored in that case there is no role for money and no role for central bank intervention in the example displayed with imperfect monitoring optimal intervention is not simple

technical efficiency in the italian performing arts companies this paper evaluates the determinants of firms technical efficiency in the italian performing arts pa sector by estimating a stochastic production frontier for an unbalanced panel of 107 firms over the period 2005 2012 the panel data setting allows us to control for both unobserved and observed heterogeneity of pa firms reaching several interesting and robust findings firstly it finds that the italian pa firms are scale inefficient as they generally operate in either an increasing or decreasing returns to scale landscape this result is reinforced by the fact that the smaller firms 10 49 employees are the most technically efficient firm size class secondly this research proves that the efficiency score is on average 66 demonstrating that pa firms output could be substantially increased without the use of new inputs thirdly it confirms that the quality matters and competences increase the efficiency in the sector finally the environmental factors especially the quality of institutions have a strong impact on technical efficiency of pa firms supporting that regional differences also exist in this sector

introducing a new currency government policy and prices abstract the aim of this article is to study the introduction of a new fiat currency within a dual currency divisible goods search model the government using price control or legal tender laws can affect the equilibrium price levels of two domestic currencies with the goal of driving the old currency out of circulation and replacing it with a new one it is shown that some equilibrium solutions that exist in a laissez faire environment disappear with government monitoring additionally when the old currency is made illegal its equilibrium value is affected differently by public measures such as conversion tax and redistribution policies finally if the enforcement power of legal tender laws is strong enough the old currency cannot be more valuable than the new one and the probability that it changes hands in trade when introducing lotteries cannot be smaller than one

endogenous supply of fiat money abstract we consider whether reputation concerns can discipline the behavior of a long lived self interested agent who has a monopoly over the provision of fiat money we obtain that when this agent can commit to a choice of money supply there is a monetary equilibrium where it never overissues we show however that monetary equilibria with no overissue do not exist when there is no commitment this happens because the incentives this agent has to maintain a reputation for providing valuable currency disappear once its reputation is high enough more generally we prove that in the absence of commitment overissue happens infinitely often in any monetary equilibrium we conclude by showing that imperfect memory can restore the positive result obtained with commitment

on the essentiality of banks we compare allocations sustained by credit with allocations sustained by bank notes inside money in a search model with decentralized trade and limited monitoring we demonstrate that there exists a credit arrangement that is superior to inside money however in contrast with inside money this arrangement is not robust to an expansion of trade that is not accompanied by an adequate increase in the degree of monitoring therefore banks are essential when trade is intense and monitoring is limited as a historical application we argue that our model helps explain the origins of banking in medieval and early modern europe

on money as a medium of exchange we analyze economies in which individuals specialize in consumption and production and meet randomly over time in a way that implies that trade must be bilateral and quid pro quo nash equilibria in trading strategies are characterized certain goods emerge endogenously as media of exchange or commodity money depending both on their intrinsic properties and on extrinsic beliefs there are also equilibria with genuine fiat currency circulating as the general medium of exchange we find that equilibria are not generally pareto optimal and that introducing fiat currency into a commodity money economy may unambiguously improve welfare velocity acceptability and liquidity are discussed

has government any role in money abstract recent interest in monetary reform has been sparked by the emergence of a world irredeemable paper money system in light of this interest we review the current validity of four good reasons friedman advanced in 1960 to rationalize government intervention we conclude that the forces that produced government involvement in the past will persist deregulation of financial intermediaries is desirable on grounds of market efficiency though it is an open question whether government should continue as lender of last resort we expect that the present world fiat money standard will neither degenerate into hyperinflation nor revert to a commodity standard

the evolution of monetary equilibrium abstract the hahn problem is that even if a monetary equilibrium with valued fiat money exists in general equilibrium a nonmonetary equilibrium with a zero price on money generally also exists why should we expect the former over the latter here i consider the preferences that will survive repeated trading in an exchange economy where agents compete in biological fitness with unobservable preferences and positive assortativity in matching evolutionarily stable preferences implement the competitive equilibrium that maximizes the sum of agents fitnesses in a standard bewley townsend model this implies selection of the monetary over the nonmonetary equilibrium and also implies the survival of agents with money in the utility function trust in fiat money is only a recent development and even today such faith is hardly universal cass and shell 1980

an ecological monetary theory abstract while money is critical to the modern world ecological economics does not have a theory of money that is applicable to its theoretical framework and policy prescriptions accordingly the field often defers to an orthodox conception of money that is historically inaccurate and ontologically inconsistent the dualized nature of western philosophy informs orthodoxy by defining money according its function as a medium of exchange this conceptualization creates logical and historical problems that can be addressed by exploring an interdisciplinary literature that defines money according to its nature as a social relation expressed in a unit of account this paper develops an ecological monetary theory that is simultaneously rooted in a socio historical understanding of money s nature and in an ontology of social and ecological embeddedness such a theory provides ecological economists and others concerned with social and ecological equity with a framework from which to address monetary systems and policy

vertical integration and dis integration of computer firms a history friendly model of the co evolution of the computer and semiconductor industries in this article we present a history friendly model of the changing vertical scope of computer firms during the evolution of the computer and semiconductor industries the model is history friendly in that it attempts at replicating some basic stylized qualitative features of the evolution of vertical integration on the basis of the causal mechanisms and processes which we believe can explain the history these factors are identified in the coevolution of capabilities the size of markets and the structure of industries in particular the basic assumption is that the principal force behind the patterns of vertical integration and disintegration of computer firms was the differential development of capabilities for designing and producing semiconductors among firms on this basis the changing boundaries of firms are analyzed in the context of dynamic and uncertain technological and market environments characterized by periods of technological revolutions punctuating periods of relative technological stability and smooth technical progress the model illustrates how the patterns of vertical integration and specialization in the computer industry change as a function of the evolving levels and distribution of firms capabilities over time and how they depend on the coevolution of the upstream and downstream sectors specific conditions in each of these markets the size of the external market the magnitude of the technological discontinuities the lock in effects in demand exert critical effects and feedbacks on market structure and on the vertical scope of firms as time goes by copyright 2008 oxford university press

existence of steady states with positive consumption in the kiyotaki wright model we prove the general existence of steady states with positive consumption in an n goods and fiat money version of the kiyotaki wright model by admitting mixed strategies we also show that there always exists a steady state in which everyone accepts a least costly to store object in particular if fiat money is one such object then there always exists a monetary steady state we also establish some other properties of steady states and comment on the relationship between steady states and incentive feasible allocations

a theory of a generally acceptable medium of exchange and barter abstract this paper develops a model that accounts both for the existence of money defined as a generally acceptable medium of exchange and for the survival of some barter exchange in economies in which money exists in contrast to jones 1976 seminal article in which individuals are restricted to fix trading strategies before entering the market the present model assumes that individuals have conditional trading strategies that allow them to effect exchange according to the types of trades they encounter in the market the analysis shows how decentralized market forces generate money and lead to a unique level of monetization

adaptive learning and the transition to fiat money this article explores some implications of adaptive learning for monetary evolution using a search theoretic framework that allows for media of exchange network effects adaptive learning precludes any voluntary transition to a fiat standard from a non monetary state of nature and can account for the historically observed tendency for fiat monetary standards to emerge only following the prior appearance of commodity money and the widespread employment of redeemable banknotes adaptive learning can also account for governments frequent resort to coercive measures to force a switch to fiat money and for their ability to affect such a switch even when doing so is not pareto optimal exchange media fall into the general category of products for which the utility that a user of the good derives from use of the good increases with the number of other agents using the good katz and shapiro 1985 p 424 there are two reasons for these positive network effects 1 indirect the more agents who employ a particular medium of exchange the more likely it is that prices will be quoted in terms of that medium of exchange i e that the medium of exchange will also serve as the economy s principle medium of account the costs of exchange are less for a medium of exchange that trades at par this indirect external effect is analogous to one encountered in computer hardware the more purchasers of a particular kind of hardware the more likely manufacturers of software are to supply compatible products 2 direct the more persons who use a particular exchange medium the better its quality or performance this direct network effect is analogous to one encountered in communications technologies such as telephones the analogy is especially close for fiat money which is useless to an isolated individual this article examines some ways in which media of exchange network effects influence the evolution of monetary standards and especially their role in determining both when and how a transition may occur from barter or commodity money to fiat money the approach taken here emphasises the role of adaptive learning where agents select exchange strategies that reflect static expectations concerning other agents preferred strategies although the exchange game agents play generally has multiple nash equilibria including one in which all agents accept fiat money adaptive learning precludes a spontaneous transition from barter to a fiat monetary standard even where a fiat standard would be welfare enhancing yet such learning does not rule out the spontaneous evolution of a commodity money standard or the eventual substitution of redeemable banknotes for commodity money readers familiar with the literature on network effects will recognise this

barter in the us economy a macroeconomic analysis in this paper a statistical model is developed to examine the determinants of the growing level of barter transactions in the us although a barter system is believed to be pareto inferior to a money system recent statistics of the estimated level of barter transactions in the us show a rapidly growing interest by large corporations as well as individuals in this type of trade the primary obstacle in empirical research in this area is the difficulty of measuring the size of barter transactions here data from barter exchange organizations are used to test the significance of several variables the ordinary least squares and cointegration and error correction models are employed as two alternative empirical techniques to analyse the data the results support the counter cyclical arguments as well as the inflation factor however the notion of tax evasion as a motive in organized barter receives only a partial support

scotland and small country independence the assessment this paper reviews some of the issues consequent on the formation of new states through secession while its particular focus relates to the potential withdrawal of scotland from the united kingdom it discusses preference heterogeneity as a potential cause of the break up of states relating that to recent developments in the economics of identity it examines some macroeconomic issues particularly debt and currency and reflects on how these might influence secession it examines alternatives fiscal decentralization to secession and considers the strategies that those arguing for and against secession may deploy it also explains the structure of this issue explaining how the different contributions come together

money barter and consumption interdependence abstract by introducing a degree of consumption interdependence into a search model we show that people may switch from using money to bartering during hyperinflation but barter activities however could still be popular even though the inflation rate is low

the size of countries does it matter borders are a man made institution and as such their shape cannot be taken as part of the physical landscape the size of countries is endogenous to politico economic forces this paper discusses recent efforts by economists to study three related questions what determines the evolution of the size of countries does size matter for economic success given the trend toward decentralization and of creation of supernational unions such as the eu is the meaning of national borders evolving jel h10

bitcoin and the legitimacy crisis of money the virtual currency and payment project bitcoin intends to challenge the current monetary and payment system that finds itself in a legitimacy crisis in the aftermath of the financial market turmoil of 2008 in examining the governance of the bitcoin system i try to assess its potential to create input and output legitimacy as a payment system and as a monetary system in comparison with current practice

commodity money under private information abstract private information is introduced into the kiyotaki wright model of commodity money in terms of qualitative uncertainty concerning the good which would be the unique medium of exchange under complete information producers are allowed to produce high or low quality versions of that good and people may not always recognize its quality it is shown that commodities that suffer from qualitative uncertainty may still be used as the medium of exchange when the private information problem is not too severe this is so despite the fact that in some equilibria there is necessarily some low quality commodity money in circulation when the information problem is so severe that the good of uncertain quality cannot be the unique money there can exist an equilibrium with dual commodity monies of which one is the good subject to qualitative uncertainty

on the welfare properties of fractional reserve banking monetary economists have long recognized a tension between the benefits of fractional reserve banking such as the ability to undertake more profitable long term investment opportunities and the difficulties associated with it such as the risk of insolvency for each bank and the associated losses to bank liability holders i show that a specific banking arrangement a joint liability scheme provides an effective mechanism for ensuring the ex post transfer of reserves from liquid banks to illiquid banks so it is possible to select a socially efficient reserve ratio in the banking system that preserves the safety of bank liabilities as a store of value and maximizes the rate of return paid to bank liability holders

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

money is memory abstract this paper examines the sets of feasible allocations in a large class of economic environments in which commitment is impossible following myerson 8 the standard definition of feasibility is adapted to take account of the lack of commitment the environments feature either memory or money memory is defined as knowledge on the part of an agent of the full histories of all agents with whom he has had direct or indirect contact in the past money is defined as an object that does not enter utility or production functions and is available in fixed supply the main proposition is that any allocation that is feasible in an environment with money is also feasible in the same environment with memory depending on the environment the converse may or may not be true hence from a technological point of view money is equivalent to a primitive form of memory journal of economic literature classification numbers e40 c73 d82

the transition from barter to fiat money how did it become possible to exchange apparently valueless pieces of paper for goods this paper provides an equilibrium account of the transition between barter and fiat money regimes the explanation relies on the intervention of a self interested government that must be able to promise credibly to limit the issue of money to achieve credibility the government must offset the benefits of seigniorage by internalizing some of the macroeconomic externalities generated by the issue of fiat money the government s patience and the extent of its involvement in the economy are key determinants of whether the transition can be accomplished copyright 1995 by american economic association

on the private provision of fiat currency this paper considers whether fiat money can be provided by a revenue maximizing monopolist in an environment where money is essential two questions arise concerning the private supply of money is it feasible and is it optimal concerning the feasibility question i show that the revenue maximizing policy is time consistent if the trading history of the issuer is public information and if money demanders respond to the revelation of defection by playing autarky concerning the optimality question the model suggests that any private organization of the market for fiat currency is suboptimal

specific investment economies of scale and the make or buy decision a test of transaction cost theory this paper develops empirical tests of three hypotheses arising from transaction cost theory as developed by oliver williamson evidence is provided from a new dataset on 178 inputs gathered from uk engineering firms the probability of buying in specialised inputs is higher if the production technology is non specific but only if there are economies of scale or scope furthermore the economies of scale scope effect is much reduced in the presence of specific assets this interactive hypothesis has not been formally tested before we also believe this to be the first cross section empirical test of transaction cost make or buy theory using european data

government transaction policy media of exchange and prices abstract we study government transaction policies in search theoretic models of money we model government as a subset of agents who are subject to the same random matching technology and other constraints as private agents but who behave in an exogenous way regarding which objects they accept in trade and at what price the objective is to see how these policies affect private agents strategies and hence the set of equilibria we analyze how the effects depend on factors like the size of government the intrinsic properties of money and the availability and efficacy of substitutes like barter or foreign currency journal of economic literature classification numbers c78 e31 e42

liquidity a new monetarist perspective this essay surveys the new monetarist approach to liquidity work in this literature strives for empirical and policy relevance plus rigorous foundations questions include what is liquidity is money essential in achieving desirable outcomes which objects can or should serve in this capacity when can asset prices differ from fundamentals what are the functions of commitment and collateral in credit markets how does money interact with credit and intermediation what can and should monetary policy do the research summarized emphasizes the micro structure of frictional transactions and studies how institutions like monetary exchange credit arrangements or intermediation facilitate the exchange process

determinants of vertical integration an empirical test this paper tests models of vertical integration with emphasis on incentives that arise from transactions costs and demand variability the tests are based on a logit analysis of firms backward integration choices in a sample of thirty four chemical products the results are consistent with recent transactions cost theories and the demand variability model proposed by carlton 1979 copyright 1991 by blackwell publishing ltd

prospective deficits and the asian currency crisis this paper argues that a principal cause of the 1997 asian currency crisis was large prospective deficits associated with implicit bailout guarantees to failing banking systems the expectation that these future deficits would be at least partially financed by seigniorage revenues or an inflation tax on outstanding nominal debt led to a collapse of the fixed exchange rate regimes in asia we articulate this view using a simple model whose key feature is that a speculative attack is inevitable once the present value of future government deficits rises we present empirical evidence in support of the key assumptions underlying our interpretation of the crisis
