a model of the bfh payments system the bfh payments system was introduced by robert l greenfield and leland b yeager in a laissez faire approach to monetary stability 6 the key element of their proposal is to dispense with base money and instead tie the means of payment to a nearly comprehensive bundle of goods and services by the institution of indirect convertibility their system promises to be free from inflation and several sources of recession while bfh was named to credit fischer black i eugene fama 3 4 and robert hall 10 11 it must not be confused with their specific institutions or arguments greenfield and yeager modified their ideas and have continued to develop the system 20 5 21 8 9 the purpose of this paper is to present a model of bfh consistent with simple textbook macroeconomics contrary to first impressions bfh is best understood using the concept of money but the absence of base money makes the quantity theory inappropriate for analysis instead a simple keynesian model illustrates the determination of interest rates real income the price level and the quantity of money aggregate supply the is relationship and money demand are conventional only the money supply process is unusual

the failure of woodford s model of the channel system in the cashless economy woodford claims to present a cashless and frictionless model of the channel system of interest rate control this note explains why woodford s frictionless model omits an essential feature of channel systems the need for clearing e cash balances at the central bank without the existence of some form of final settlement on the books of the central bank channel systems collapse woodford makes this conceptual error because he assumes that moneyless accounting systems of exchange can be applied to model e cash economies

a model of nominal contracts a model is produced in which labor contracts that prespecify unindexed nominal wage payments arise endogenously these contracts function as a self selection mechanism under appropriately different attitudes toward price level risk which can either arise directly from preferences or be induced by different patterns of asset holdings nominal contracts allow high productivity workers to signal their type by their willingness to accept unindexed contracts this explanation of nominal contracts does not require that money be used in any particular set of transactions and nominal contracts enhance the risk faced by all parties accepting them

the development of the new monetary economics this paper looks into the history of economic thought to examine the forerunners of the new monetary economics this approach emphasizes the role of regulations on private financial intermediation in determining the particular institutional arrangements that contemporary monetary theory treats as data the new view investigates the possibility that under laissez faire the unit of account and means of payment traditionally bundled together in the item called money may become separated the earlier writers who share this perspective have been overlooked by historians of economic thought as well as by recent contributors to the new monetary economics an examination of these theorists is of more than historical interest for many of their insights and analyses are relevant to modern monetary theory

real exchange rates and macroeconomics a selective survey the paper discusses real exchange rate issues of industrial and of developing countries for real exchange rates among the key industrial countries we ask what is the best conceptual framework to shed light on this question we look at alternative theoretical approaches and at empirical evidence on the relation among interest rates expectations and depreciation the discussion of developing countries real exchange rates focuses on the link between real exchange rates real wages and the profitability of capital the model highlights the discrepancy between the mobility of capital including in the long run physical capital and

a theory of monetary exchange the transactions cost for alternative exchange mechanisms for the household exchange problem can be characterized by the computational complexity of the exchange process the computational complexity for any exchange mechanism is at least nh where n is the number of goods and h is the number of households imposing the conditions of conservation nonnegativity and quid pro quo results in a command exchange mechanism whose computational complexity is nh multiparty barter exchange formalized using graph theory has computational complexity

using survey data to test standard propositions regarding exchange rate expectations survey data provide a measure of exchange rate expectations superior to the forward rate in that no risk premium interferes we estimate extrapolative adaptive and regressive models of expectations static or random walk expectations and bandwagon expectations are rejected current appreciation generates the expectation of future depreciation because variables other than the contemporaneous spot rate receive weight in comparing expectations to the process governing the spot rate we find statistically significant bias no variable is as ubiquitous in international financial theory and yet as elusive empirically as investors expectations regarding exchange rates in the past expectations have been modeled in an ad hoc way often by using the forward exchange rate there is however a serious problem with using the forward discount as the measure of the expected change in the exchange rate in that the two may not be equal the gap that may separate the forward discount and expected depreciation is generally interpreted as a risk premium most of the large empirical literature testing the unbiasedness of the forward exchange rate for example has found it necessary either arbitrarily to assume away the existence of the risk premium if the aim

separation of unit of account from medium of exchange the separation of a unit of account uoa from a medium of exchange moe in the commodity money system is investigated by considering explicitly a seller s choice of uoa in terms of either an moe or a unit of metal weight if the likelihood of debasement of an moe and its rate are high enough the price is posted in terms of a unit of metal weight rather than an moe interestingly this moe uoa separated equilibrium yields the flexible nominal price whereas an moe uoa integrated equilibrium yields the sticky one this implies the nominal price rigidity in the fiat money system where moe and uoa are integrated

existence and stability of conventions and institutions in a monetary economy the example of money illustrates that the role of history is crucial in explaining the emergence and persistence of conventions and institutions this implies that in analyzing money and monetary institutions the usefulness of the general equilibrium analysis and game theory which both draw upon an instrumental concept of rationality is limited in our view a fruitful analysis of conventions and institutions has to take account of the importance of historical contingencies and the fundamental incompleteness of individual knowledge

money a market microstructure approach the current discussion about the future of the financial system draws heavily on a set of theories known as the new monetary economics the new monetary economics predicts that deregulation and financial innovation will lead to a moneyless world this paper uses a market microstructure approach to show that a common medium of exchange that serves as unit of account will remain a necessary instrument to reduce transaction costs this finding is supported by empirical evidence from foreign exchange markets

can we improve the structure of financial systems 1993 the main theme of this paper is that several of the characteristics of our present western monetary and banking systems have been crucially dependent on the particular temporal process of historical development and are not an essential feature of more fundamental preferences or technological conditions they exist in part because we take them for granted it is the purpose of this paper to examine what might change in both theory and practice if some of these inessential characteristics were to be changed

on the consistency of short run and long run exchange rate expectations abstract this paper examines whether short term exchange rate expectations overreact by comparing them with long term expectations we develop a set of nonlinear restrictions linking expectations at different forecast horizons the restrictions impose consistency a property weaker than rationality we use exchange rate survey data to measure expectations and then test whether consistency holds the data show that a current positive exchange rate shock leads investors to expect a higher long run future spot rate when iterating forward their short term expectations than when thinking directly about the long run in this sense short horizon expectations may overreact to current exchange rate changes

the mechanics of indirect convertibility this paper sets out the mechanics and equilibrating processes of indirectly convertible monetary systems in which currency issuing banks redeem their currency with redemption media of the same value as the commodity or commodity basket that defines the dollar it goes on to investigate the paradox of indirect convertibility and suggests that indirect convertibility is feasible despite the paradox finally it assesses the systems of fisher hall and others that have been suggested as alternatives to indirect convertibility but concludes that these alternative systems are open to serious objections copyright 1995 by ohio state university press

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

an empirical analysis of ex ante profits from forward speculation in foreign exchange markets this paper constructs a time series band for ex ante profits from forward speculation and examines the permanent component of the median of the band for six different exchange markets the unpredictability of ex ante profits is rejected using nonparametric tests deviations of ex ante profits from forward premia are attributed to deviations of nominal exchange rates from martingale processes it is shown that movements in the terms of trade are responsible for most of the variability and serial correlation properties of ex ante profits t is by now widely recognized that the forward rate is not an unbiased predictor of future spot rates and that realized nominal profits from spec ulating in the forward market are nonnegligible and highly volatile see e g hodrick 1987 frankel and meese 1987 however the nature of these profits is as of yet undetermined this paper attempts to shed light on this issue by examining the time series properties of ex ante profits from forward speculations in six foreign exchange markets i focus on three aspects of the problem first i provide a measure of the range and the variability of ex ante profits two issues with contradictory evidence in the literature see hodrick 1987 and frankel 1988 for refer ences second i relate deviations from uncov ered interest parity to risk and to deviations of nominal spot rates from martingale processes third i link the time series properties of ex ante profits to the behavior of the real exchange rate since ex ante profits are not observable the empirical analysis requires the construction of a time series for the expected future spot rate frankel and froot 1987 ito 1988 cumby 1988 and diebold and nason 1990 have all suggested ways of computing this series here i provide an alternative method for constructing a time series for expected future spot rates and for statistically assessing the properties of ex ante profits expected future spot rates are measured as a 90 confidence band obtained from the simulated recursive distribution for the linear predictor of the series i simulate the distribution of the linear predictor rather than use simple point forecasts in order to reduce the forecast error due to parameter uncertainty an addi tional measure for expected future spot rates considered is a point estimate of the permanent component of the median of the band i use nonparametric tests to examine the rela tionship between ex ante profits and other series nonparametric tests are employed here for two reasons first i am interested in the entire popu lation properties of the data existing results are derived by examining only the first and second moments of the data second efficiency tests are generally based on linear parametric functional forms pagan and ullah 1988 have pointed out problems with these tests when the conditional mean of the data is nonlinear nonparametric tests overcome these problems the results indicate that nominal and real rates do not follow martingale processes that a risk premium rarely explains the behavior of the ex ante profits and that variations in expected terms of trade account for the time series proper ties of ex ante profits

a laissez faire approach to monetary stability this paper develops some diverse hints for a new monetary system offered separately by fischer black eugene fama and robert e hall for reasons that will become evident though we should perhaps say payments system instead of monetary system none of the economists mentioned has actually proposed the particular system set forth here nor examined all its properties and we call it the bfh system not to implicate them but only to give credit for some component ideas and to have a convenient label l regardless of who if anyone may actually advocate the system contemplating it is instructive it illuminates by contrast some characteristics of our existing and recent systems

credit constraints and demand for higher education evidence from financial deregulation abstract we use staggered banking deregulation across states in the united states to examine the impact of the resulting increased credit supply on college enrollment from the 1970s to the early 1990s our research design produces estimates that are not confounded by wealth effects due to changes in income or housing wealth we find that lifting banking restrictions raises college enrollment by about 2 6 percentage points 4 9 we rule out alternative interpretations by examining results for different income groups and bankrupt households we also find similar effects for two year or four year college completion and supporting evidence in household educational borrowing

legal restrictions and monetary evolution abstract the legal restrictions school of monetary theory hypothesizes that the use of ordinary currency would die out if legal tender laws were abolished instead interest bearing instruments would be used in transactions this paper refutes the claim as far as it applies to money as a medium of exchange the network externality or coordination convention properties of a medium of exchange imply that the strategy of holding interest bearing instruments is not necessarily individually dominant there is a critical mass of users that has to be assembled before a switch can occur

are foreign exchange forecasts rational new evidence from survey data abstract tests of rationality in foreign exchange markets have been inconclusive because of disagreement over the relevant asset pricing model this paper uses a newly available set of data on foreign exchange expectations to directly test the rationality of four foreign currency markets overall the results reject the rational expectations hypothesis

further evidence on exchange rate expectations abstract this paper considers a previously unexploited survey data set of exchange rate expectations which allows us to focus on differences between ems and dollar exchange rates we corroborate the earlier finding in the literature that exchange rate forecasts are not rational and that agents do not use all available information efficiently although extrapolative and adaptive expectations formation mechanisms describe non ems exchange rate expectations to a certain extent ems exchange rates forecasts seem to follow long run fundamentals more closely and would suggest that agents believe that ems exchange rate expectations undershoot their long run equilibrium values jel f31

competitive payments systems comment view lawrence h white criticizes several recent proposals for monetary reform including what we 1983 call the bfh system under this system the government precluded from issuing money would merely define a new unit of account and encourage the unit s general adoption by using it in all its own pricing contracting and accounting the definition would run in terms of so comprehensive a bundle of precisely gradable items with continuously quoted prices that the new unit would have a stable general purchasing power

asymmetric information and optimal bank reserves one traditional argument in favor of bank reserve requirements holds that since a b ank and its depositors are asymmetrically informed as to the bank s reserve position and its portfolio the bank will hold too few reserves and too risky a port folio this being the case presumably a central banking authority is equipped t o impose and to monitor a minimal reserve requirement yielding a pareto superior outcome this paper analyzes this position in the context of a formalmodel and shows that at least for some parameters of the model there is such a case for a minimal reserve requirement copyright 1987 by ohio state university press

scottish banking before 1845 a model for laissez faire during the free banking era in eighteenth and early nineteenth century scotland there were a number of legal restrictions affecting the evolution of the system scottish banking was characterized by restrictions on small denomination and interest bearing notes there were also restrictions inhibiting the development of capital markets and entry into banking furthermore the bank of england operated as a shadow central bank for the scottish system these considerations call into question the use of the scottish banking experience as the appropriate model for laissez faire and as evidence against the legal restrictions theory of money and the new monetary economics copyright 1989 by ohio state university press
