alternative approaches to money and growth this paper reexamines the issue of money and growth in an economy with both endogenous labor supply and endogenous capital stock using three recently developed approaches the money in the utility function approach the cash in advance approach and the transactions costs approach by establishing a qualitative equivalence between alternative setups the authors find economically justifiable conditions such that all comparative statics results derived from the aforementioned approaches are identical copyright 1992 by ohio state university press

the demand for assets through a low interest rate environment asset demand is important in many areas of economics to investigate this we estimate a globally flexible dynamic fourier asset demand specification and calculate morishima elasticities of substit

an intertemporally quasi separable demand system on the assumption that the natural root of dynamics lies in the intertemporal dimension of the optimization process and that an operational and meaningful solution has to be found by appropriately placing restrictions on preferences this paper develops and tests on u k 1952 81 data a dynamic demand system exploiting w m gorman s concept of quasi separability comparison with a static intertempora lly weakly separable alternative provides further evidence for the i dea that dynamic modeling can overcome the usual rejection of theoret ical constraints in demand analysis copyright 1987 by mit press

are risky assets substitutes for monetary assets i introduction financial innovation over the past couple of decades has enhanced the liquidity of many financial assets particularly noncapital certain risky assets further financial assets previously not regarded as monetary assets such as mutual funds and particularly money market mutual funds now provide monetary services such as liquidity and transactions services l given the increased liquidity of such funds the question arises as to whether risky assets are substitutes for capital certain monetary assets if noncapital certain assets are indeed substitutes for capital certain assets and are also being used for transactions purposes then agents may be treating risky assets as money although this issue has been addressed in the united states in the context of the addition of bond funds to m2 by for example duca 1995 no such research has yet been conducted in the united kingdom including risky assets in the analysis contradicts the work of ando and shell 1975 spencer 1986 appendix i pp 184 93 and spencer 1994 broadly they argue that since some nonrisky assets provide monetary services and probability also liquidity individuals would not hold risky assets for these purposes 2 in contrast hicks 1935 states that falling transaction costs and rising wealth encourages individuals to increase the proportion of risky assets in portfolio holdings most studies generally assume that risky assets fail to provide significant monetary services and for example have been excluded from the asset demand analysis of barr and cuthbertson 1991a drake fleissig and swofford 1997 and money demand studies such as taylor 1987 belongia and chrystal 1991 drake and chrystal 1994 and drake 1996 alternatively barr and cuthbertson 1991b use only risky assets in their asset demand system analysis the degree of substitution between risky assets and capital certain assets is an empirical issue while noncapital certain risky assets mutual funds and other financial assets may well be becoming closer substitutes for what people are using as money they are in no way perfect substitutes for the highly liquid cash assets to evaluate the role of noncapital certain assets we construct a noncapital certain risky divisia aggregate consisting of equities government bonds and unit trusts the divisia index allows for less than perfect substitution between assets and weights component assets according to their differing degrees of moneyness which may vary over time due to many factors for example financial innovation see barnett 1980 this methodology has been widely applied to monetary aggregation and money demand studies in a number of countries as in belongia 1996 drake 1996 drake and chrystal 1997 and anderson jones and nesmith 1997 to determine whether risky assets are substitutes for capital certain assets we use two other divisia aggregates constructed from traditional measures of money the first of these is an aggregate of highly liquid zero yield cash assets given that the component assets all have zero own rates of return however divisia aggregation is equivalent in this case to simple summation the second aggregate is a divisia aggregate of interest bearing capital certain assets including risky assets complicates the analysis because the degree of risk aversion will affect the estimates of substitution between capital certain and noncapital certain assets thus we also analyze how different degrees of risk aversion affect the results the substitution relationship between assets is estimated from an asymptotically ideal model aim the choice of an aim is in line with the recommendation of barnett fisher and serletis 1992 that flexible systems of demand equations should be used that allow for nonlinear optimizing behavior by economic agents furthermore this paper can be seen as an extension of the recent application of this model to u

probability models and robust policy rules abstract we consider sims s 2008 argument that robust policy making requires that policy models be treated as probability models in a welfare based setting we estimate by bayesian methods a number of variants of a new keynesian macroeconomic model and use both the model odds and posterior densities to design robust interest rate rules consisting of an inflation forecast based rule and a wage targeting one each are shown to have distinct robustness qualities and distinct implications for the probability models approach to ensure feasible policy we further impose that rules are stable determinate and lower bound compatible our results have important implications for the design evaluation and analysis of the probability models approach to robust monetary policy making

the rationale of the mean standard deviation analysis skewness preference and the demand for money publisher summary this chapter discusses the rationale of the mean standard deviation analysis skewness preference and the demand for money in january 1969 issue of the review of economic studies karl borch and martin feldstein separately criticized the widely used mean variance analysis of portfolio selection borch contended that any system of upward sloping mean standard deviation e s indifference curves can be shown to be inconsistent with the basic axiom of choice under uncertainty he pointed out that one can always pick any two points on an upward sloping indifference curve to represent two bernoulli distributions with probability 1 p of gaining the same amount x in both the cases and probability p of gaining y1 in the case of one distribution and y2 in the case of the second distribution with y2 y1 if the second distribution represents the point to the northeast of the other point then by the dominance axiom the second distribution must be preferred to the first which contradicts the basic meaning of indifference curves feldstein by using a log utility function and a lognormal distribution for investment outcome showed that e s indifference curves for a risk averter need not be convex downwards though upward sloping they would change from convex to concave once the standard deviation of the outcome exceeds the mean multiplied by on the face of it this seems to suggest that risk aversion might decrease as risk is increased beyond a certain extent

neoclassical consumer demand theory and the demand for money m friedman 1956 suggests that the demand for money should be analyzed in terms of consumer demand theory although often the interpretation of empirical results from studies using aggregate data appears to be in terms of the motives approach i e transactions precautionary and speculative motives the authors develop friedman s ideas within an explicit model of consumer theory and find that they provide a consistent framework for analyzing portfolio choice and offer greater insights into results from aggregate studies of the demand for money than the motives approach in particular the authors provide a new interpretation of the role of nominal interest rates inflation and a hicksian measure of wealth in the demand for money function copyright 1991 by royal economic society

the green golden rule habit and anticipation of future consumption abstract we derive the green golden rule ggr in the habit formation hf and anticipation of future consumption afc frameworks since consumption is the key variable of ggr time non separabilities in preferences over consumption streams given by the afc and hf may have important impacts on the environment and sustainability we demonstrate that agents who smooth their consumption patterns according to the hf hypothesis are more likely to preserve the environment than those who anticipate future consumption or who do not so smooth consumption

portfolio behaviour in a flow of funds model for the household sector in india we estimate a flow of funds model for the household sector in india within the almost ideal demand system aids framework and examine the demand for money and the substitution effects between money and other financial assets the restricted long run model obtained using cointegration techniques provides stable equilibrium relationship between i 1 variables and broadly satisfies the axioms of rational choice in consumer demand theory we find that financial sector reform exerts a significant impact on the interest rate structure and household portfolio preferences specifically there is strong substitutability among risk free assets and a possible speculative effect in the stock market while the exchange rate strongly influences the demand for money these findings all have important policy implications

a semi nonparametric approach to the demand for uk monetary assets we estimate an asymptotically ideal model of the demand for uk personal sector monetary assets we use data that are consistent with utility maximizing behaviour and find that uk monetary assets are generally substitutes in use the estimated elasticities of substitution during the 1980s and the early 1990s indicate that a relatively broad monetary aggregate should be used in economic studies the results also suggest that any policy based on interest or user cost elasticities of substitution between financial assets should be based on the morishima elasticities as the allen uzawa calculation can give misleading results

habit formation in consumption and its implications for monetary policy models this paper explores a monetary policy model with habit formation for consumers in which consumers utility depends in part on current consumption relative to past consumption the empirical tests developed in the paper show that one can reject the hypothesis of no habit formation with tremendous condence largely because the habit formation model captures the gradual hump shaped response of real spending to various shocks the paper then embeds the habit consumption specication in a monetary policy model and nds that the responses of both spending and inflation to monetary policy actions are signicantly improved by this modication jel d12 e52 e43

habit formation in a monetary growth model abstract this paper introduces the hypothesis of habit formation in consumption in the sidrauski am econ rev papers proc 57 1967 534 model a number of results are derived 1 as in the sidrauski model money is superneutral and the friedman rule still provides the optimal quantity of money 2 the demand for money in this model is greater than in the sidrauski model 3 the money demand reflects the habit persistence related to past consumption and the rate of time preference and it is more sensitive to changes in inflation and nominal interest rates than the sidrauski model

non parametric tests of consumer behaviour the neoclassical model of consumer behaviour postulates that a consumer s choice behaviour can be described as deriving from utility maximization subject to a budget constraint one is then naturally led to ask what this model implies about observed behaviour this question has been addressed from two quite distinct approaches the first approach originating in the work of slutsky 1915 and antonelli 1886 derives necessary and sufficient conditions involving the derivatives of the demand functions the second approach originating in the work of samuelson 1938 1947 1948 derives algebraic conditions on the demand functions implied by maximizing behaviour

do homeowners increase consumption after the last mortgage payment an alternative test of the permanent income hypothesis the maturity date of a mortgage loan marks the end of monthly mortgage payments for homeowners in the period after the last payment homeowners experience an increase in their disposable income our study interprets this event as an anticipated increase in income and tests whether households smooth consumption over the transition period as predicted by the rational expectation life cycle permanent income hypothesis we find households do not alter nondurable goods consumption in the period following the last mortgage payment instead they increase both financial savings and savings in durable goods such as house furnishings and entertainment equipment in the year of the last mortgage payment

the search for a stable money demand function a survey of the post 1973 literature phe question of whether the demnand function for money is stable is one of the most important recurring issues in the theory and application of macroeconomic policy what is being sought in a stable demand function is a set of necessary conditions for money to exert a predictable influence on the economy so that the central bank s control of the money supply can be a useful instrument of economic policy as such the notion of a stable demand function appears to involve three key elements e g john t boorman 1976 p 317 and david e w laidler 1977 pp 34 35 first the demand for money relation should be highly predictable in a statistical sense as measured by the usual goodness of fit statistics precision of estimated coefficients and presumably its ability to forecast accurately out of sample second a stable demand function for money has relatively few arguments a relationship that requires knowledge about a large number of variables in order to pin it down is in effect not predictable finally the variables that appear as arguments in the function should represent significant links to spending and economic activity in the real sector in sum a stable demand function for money means that the quantity of money is predictably related to a small set of key variables linking money to the real sector of the economy the importance of a stable money demand function for monetary policy can be illustrated with the standard is lm model in which interest rates and gnp are the endogenous variables in this context a stable demand function for money translates into a well defined relationship between money interest rates and gnp

nonparametric demand analysis of u k personal sector decisions on consumption leisure and monetary assets a reappraisal this paper utilizes a new data set to test for utility maximizing behavior and weakly separable subutility functions in the context of a utility function comprising durables nondurables services leisure and monetary asset holdings for the u k personal sector all the data sets analyzed demonstrated consistency with respect to utility maximizing behavior the weak separability results prove to be relatively invariant to the degree of aggregation over goods but highly sensitive to the assump tion made regarding the representative consumer per household scaling of the data produced a utility function that is weakly separable in goods services and leisure and in monetary assets

an intertemporal system of dynamic consumer demand functions abstract this paper constructs and estimates a system of dynamic consumer demand equations under the assumption of rational expectations about anticipated human wealth the traditional one period budget constraint is replaced by the lifetime anticipated wealth constraint lagged dependent variables are rationalized by an adjustment cost argument in the model presented both the dynamic adjustment coefficients as well as the parameters characterizing the underlying long run preferences are identified and can be estimated we find that a weak version of the reh cannot be rejected on the data in common with most empirical studies on demand behaviour we have to reject the symmetry restrictions

econometric modelling of international carbon tax regimes an econometric model of fossil fuel demand has been estimated for eight oecd countries relating coal oil and gas demands to gdp and prices in addition a model of endogenous technical progress has been estimated aiming to include both price induced innovation in energy and structural change in the economy as long term determinants of energy consumption a number of possible international carbon energy tax agreements are simulated showing the impacts on carbon dioxide emissions and comparing the two models in the long run the magnitude of taxes required to stabilize or reduce emissions would be large and there are important differences between countries in price responses which must be taken into account in international modelling and policy formulation

asset portfolios and credit rationing evidence from kenya this paper presents a model of the private sector s demand for financial and real assets in kenya for the period 1973 90 the private sector is assumed to hold its wealth in terms of five assets but is quantity rationed in the credit market the model is estimated as a co integrated demand system based on the almost ideal demand system of deaton and muellbauer 1980 the model highlights the role of real asset accumulation in offering a hedge against inflation and the role of credit rationing in the composition of wealth asset markets in developing countries and particularly those of sub saharan africa have typically been subject to controls on prices through interest rate controls and quantities through credit rationing it is natural to ask how these controls affect the level composition and evolution of private sector wealth for example how does the wealth portfolio respond to changes in the level of credit rationing how do controls on nominal interest rates determine the private sector s response to inflation since these questions are not readily addressed using conventional single equation models of money demand this paper examines them within a more general model of portfolio choice in which relative asset price effects and quantity rationing in the market for domestic credit are made explicit the econometric model which is similar to that of taylor and clements 1983 perraudin 1987 and barr and cuthbertson 1991 1992 1994 is based on a dynamic representation of the almost ideal demand system adapted to handle rationing using aggregate time series data for kenya the model characterizes the asset portfolio chosen by a representative private sec tor agent facing a two stage budgeting problem in the first stage the represen tative agent chooses his or her labour supply and consumption and hence the net addition to wealth at the second stage the new stock of wealth adjusted for capital and exchange rate gains or losses is allocated across different assets which in this case consist of money bank deposits and loans the latter being treated as negative assets real assets in the form of equity claims and govern ment securities the demand shares for the components of the portfolio are then estimated within an error correction system of equations the model is estimated on quarterly data for the period 1973 90 2 there are a number of reasons for adopting this particular approach first and most obviously the demand system provides for a more comprehensive description of the evolution of the overall portfolio composition than is poss ible using traditional single equation approaches this is particularly true in

quality disclosure and competition we analyze costly quality disclosure with horizontally differentiated products under duopoly and a cartel and characterize the effect of competition on disclosure and welfare we show that expected disclosure is higher under a cartel than under duopoly and the welfare comparison depends on the level of disclosure cost when the disclosure cost is low welfare is higher under a cartel than duopoly but when the disclosure cost is high welfare is higher under duopoly in either market structure disclosure is excessive in terms of total surplus but insufficient in terms of consumer surplus

microfoundations and the demand for money the reader should note that i write this piece in a style that aims to be accessible to that much neglected representative agent the woman on the eurostar train hence unlike the man on the clapham omnibus i assume my intrepid traveller has reasonable knowledge of monetary economics and econometrics but not of the details of the demand for money space constraints force me to indulge in a certain amount of poetic licence but i hope this results in poetic justice there have been many wars fought on this particular battlefield some with almost religious zeal on the theoretical side of the debate we sometimes have the equivalent of religious fundamentalists be they muslims jews christians etc who would dismiss almost any evidence unless it were associated with a strong microtheoretic basis as laid down in the koran talmud or bible the empirical side encompasses agnostics atheists as well as born again econometricians pure theorists inhabit the sunlit uplands while applied economists and policymakers flounder in the muddy plain below occasionally gaining solace from their copy of zen and the art of motorcycle maintenance in general in economics we do not have the luxury of controlled experiments as is the case in the natural sciences what distinguishes good microfoundations from bad and how to weight priors and statistical evidence is subject to much dispute leamer i983 hendry et al i990 as in religion sometimes there is the occasional miracle proclaimed after a suitable interval a new saint may be declared and disciples flock to the new shrine later doubts may arise as to whether a miracle really did occur human behaviour is difficult to explain let alone predict so the search for the equivalent of the holy grail ark of the covenant etc is bound to be arduous in scholarly journals we generally read of the success of the demand for money like diplomats who are sent abroad to lie for the good of their country publication may require applied economists to be somewhat economical with the actualite lovell i983 leamer i983 in this article i want to be as honest as possible about our success and failures in this area the prior information an armchair economist would consider when thinking about the demand for money over the past 40 years in western industrialised countries which have experienced moderate inflation might

psychological expected utility theory and anticipatory feelings we extend expected utility theory to situations in which agents experience feelings of anticipation prior to the resolution of uncertainty we show how these anticipatory feelings may result in time inconsistency we provide an example from portfolio theory to illustrate the potential impact of anticipation on asset prices

quality disclosure formats in a distribution channel firms normally disclose quality information to consumers using two alternative formats either directly to consumers or indirectly through downstream retailers this study investigates optimal disclosure strategies formats in a channel setting with bilateral monopolies it shows that retail disclosure leads to more equilibrium information revelation this is because the manufacturer can through wholesale price cuts partially absorb the retailer s effective disclosure cost and thus increase the retailer s incentive for disclosure the conditions under which a particular disclosure format arises as the manufacturer s optimal choice are also examined even though direct disclosure is the ex post dominated option the manufacturer may benefit from committing ex ante to the direct disclosure format when the cost of disclosure is sufficiently high

the impact of consumer attentiveness and search costs on firm quality disclosure a competitive analysis firms can invest to disclose quality information about their products to consumers but consumers are not always perfectly attentive to these disclosures indeed technologies such as digital video recorders have increased the ease with which disclosures can be avoided by consumers although such inattention may result in a consumer missing information from one or more competing firms consumers who have missed disclosures might decide to search for quality information to become fully informed before making a purchase decision in this paper we incorporate consumer attentiveness as well as the related endogenous search decision into a model of quality disclosure our results suggest that firms should disclose less quality information as the share of partially informed consumers informed about one firm but not the other increases or as consumer search costs increase we also provide insights into the potential impact of consumer trends toward lower attentiveness and lower search costs this paper was

subjective price search and price competition abstract in this paper we study price rivalry between two firms facing a population of imperfectly informed buyers the two sellers are geographically dispersed and consumers search for the lowest price the competitive process either suffers from cyclical instability or stabilises at that price at which no buyer searches

quantifying and sustaining welfare gains from monetary commitment abstract our objectives are to quantify the stabilization welfare gains from commitment to examine how commitment to an optimal rule can be sustained as an equilibrium to find a simple interest rate rule that approximates the optimal commitment one we utilize an empirical micro founded euro area dsge model a quadratic approximation of household utility as the welfare criterion employing a nominal interest rate lower bound in contrast to previous studies we find significant commitment stabilization gains of around a 0 4 0 5 equivalent permanent consumption increase and with higher price stickiness gains over 2 we find that a simple optimized commitment rule responding to inflation and the real wage mimics the optimal one

anticipation and the valuation of delayed consumption this paper presents a model of intertemporal choice that incorporates savoring and dread i e utility from anticipat ion of delayed consumption the model explains why an individual with positive time preference may delay desirable outcomes or get unpleas ant outcomes over with quickly contrary to the prediction of convent ional formulations of intertemporal choice implications of savoring and dread for savings behavior empirical estimation of discount rate s and public policy efforts to combat myopic behavior are explored the model provides an explanation for common violations of the indepe ndence axiom as applied to intertemporal choice copyright 1987 by royal economic society

investment choice and asset allocation of italian households the discrete continuous approach financial and monetary policies are considered to be effective depending on the reaction of financial markets which are increasingly populated by households in this article from intertemporal settings i derive a financial almost ideal fai demand system and i estimate it by highlighting the determinants of both limited participation to financial markets and asset substitutability complementarity in the allocating stage finally the wealth elasticities provide some further insights on the low diffusion of the newer and more complex financial instruments across italian households

the demand for money and goods in the theory of consumer choice with money when monetary balances are introduced into the consumer s utility function and budget constraint the resulting demand functions for money and for the consumption goods in general do not exhibit the standard slutsky hicks properties many researchers have studied this issue and have attempted to remedy the outcome for example see m morishima 1952 c lloyd 1964 1971 j hadar 1965 and dusansky kalman 1972 1973 their paramount goal has been to provide a neoclassical integration of money demand and consumer choice theory that will yield the traditional testable demand predictions that are the hallmark of neoclassical microeconomic theory the most recent work on this subject is by samuelson sato 1984 they convincingly demonstrate that with a weakly separable utility function it is possible to reinstate symmetry and negative semidefiniteness and to generate testable predictions in this paper however i show that these predictions are not those of traditional theory but a modification of them having alternative implications for example the assumption of a non inferior good is no longer sufficient to ensure a downward sloping own demand curve the problem is that the weak separability assumption is not sufficient to recover the traditional properties i present an alternative class of utility functions for which the commodity demand functions do exhibit the usual slutsky hicks properties this result also holds for money demand i implications of the sanuelson sato results

anticipation of future consumption a monetary perspective we adapt the monetary model sidrauski 1967 to study the hypothesis of anticipation of future consumption we assume that anticipation of future consumption affects an agent s instantaneous utility and that all effects of future consumption on current well being are captured by the stock of future consumption monetary policy effectiveness is thereby reduced and a zero nominal lower interest rate and thus the friedman rule is destabilizing given this we can derive a just stable equilibrium nominal interest rate with matching definitions for inflation and monetary growth we demonstrate that these implied lower bounds match their historical analogues well

the translog utility function and the demand for money in the united states in recent years considerable effort has been directed towards establishing the nature of the relationship between money and nearmonies but with mixed success the approaches vary from multi interest rate single equation studies to the careful simultaneous equations studies summarized and amended by feige and pearce 1977 and extended recently by donovan 1978 offenbacher 1979 and barnett 1980 the empirical results also vary with numerous studies favoring only one interest rate see the surveys in fisher 1978 1983 some claiming that a variety of entities are close substitutes for money e g chetty 1969 and others showing that weak substitution or even complementarity may be the result of the measurement of elasticities of substitution between money and a number of other assets e g feige and pearce 1977 offenbacher 1979 and barnett 1980 the debate seems to have overshadowed a second and equally intriguing issue which centers on the establishment of an acceptable definition of money the basic idea of this study is to take an approach that takes account of the different degrees of moneyness possessed by the various monetary assets this paper produces quantitative estimates of the degree of substitutability of other monetary assets for money in the context of a flexible functional form model with a

is there a retirement consumption puzzle evidence using subjective retirement expectations abstract previous research finds a systematic decrease in consumption at retirement a finding that is inconsistent with the life cycle permanent income hypothesis if retirement is an expected event in this paper we use workers subjective beliefs about their retirement dates as an instrument for retirement after demonstrating that subjective retirement expectations are strong predictors of subsequent retirement decisions we still find a consumption decline at retirement for workers who retire when expected however our estimates of this consumption fall are about a third less than those found when we instead rely on the instrumental variables strategy used in prior studies
