money demand and seigniorage maximizing inflation conventional estimates of the seigniorage maximizing inflation rate often make use of the cagan form which implies a constant semielasticity of money demand with respect to inflation this paper shows that the elasticity of substitution in transactions between money and bonds determines how the inflation semielasticity of money demand changes as inflation rises allowing for a variable semielasticity estimates of seigniorage maximizing inflation for a panel of eleven high inflation countries are lower than those obtained by using the cagan form estimates based on the correct measure of the opportunity cost of money also differ sharply from those obtained when using conventional inflation measures copyright 1995 by ohio state university press

financial intermediation reserve requirements and inside money a general equilibrium analysis abstract reserve requirements are examined in a general equilibrium context the paper develops a simple general equilibrium model that includes diverse opportunities for investment and a role for financial intermediaries two versions of the model are considered one is a thought experiment in which currency serves purely to satisfy legal reserve requirements the other is more realistic the model is used to analyze the comparative static effects of changes in reserve requirements the effects of changes in other parameters of the economy in the presence of reserve requirements and some qualitative issues raised by reserve requirements

when is stabilization expansionary evidence from high inflation countries which stabilize from high inflation here defined as an annual rate above 40 usually have output expansions in the first and subsequent years of stabilization these expansions occur in both exchange rate based and money based stabilizations the paper reaches these conclusions after examining a sample of all 28 episodes in the international data that meet a pre defined criterion for stabilization from high inflation the results do not change with alternative growth and stabilization definitions the paper documents similar expansionary stabilizations in historical data and in the recent experience of the former communist economies expansionary stabilizations may be an indirect confirmation of recent theories of political economy that predict that stabilization will not occur until the gains are very large william easterly

consumption and the credit market abstract this paper uses a kalman filter model to allow the fraction of current income consumers to vary over time and shows that these consumers are liquidity constrained by relating this percentage to measures of credit market tightness

the austral plan in recent years several countries have experienced extremely rapid inflations but without total collapses of the national currencies argentina was one of those cases by mid 1985 the rate of price increase exceeded 30 percent per month however prices continued to be set in pesos and there remained a sizeable volume of short term nominal contracts the treatment of such inflations poses several questions what is the desirable speed of disinflation what mix of instruments can effectively act on prices without causing an excessive fall in real income how can prices be kept on a stable or moderately rising trend the austral plan announced in june 1985 combined fiscal measures with a price wage freeze and a monetary reform linked to a system for the conversion of debt contracts the program quite successfully managed the transition to a much lower inflation rate while real output recovered rapidly after an initial contraction still inflationary forces remained strong the problem of achieving a sustained stabilization proved quite difficult to solve this paper briefly describes the program and its effects with some references to current debates on stabilization policies see my 1986 study for full discussion and details

on the stability of the excess sensitivity of aggregate consumption growth in the usa summary this paper investigates whether there is time variation in the excess sensitivity of aggregate consumption growth to anticipated aggregate disposable income growth using quarterly us data over the period 1953 2014 our empirical framework contains the possibility of stickiness in aggregate consumption growth and takes into account measurement error and time aggregation our empirical specification is cast into a bayesian state space model and estimated using markov chain monte carlo mcmc methods we use a bayesian model selection approach to deal with the non regular test for the null hypothesis of no time variation in the excess sensitivity parameter anticipated disposable income growth is calculated by incorporating an instrumental variables estimation approach into our mcmc algorithm our results suggest that the excess sensitivity parameter in the usa is stable at around 0 23 over the entire sample period copyright 2016 john wiley sons ltd

investment subsidies and pro poor growth in rural india this article reviews the trends in government subsidies and investments in and for indian agriculture develops a conceptual framework and a model to assess the impact of various subsidies and investments on agricultural growth and poverty reduction and presents reform options with regard to re prioritizing government spending subsidies in credit fertilizer and irrigation have been crucial for small farmers to adopt new technologies particularly during the initial stage of the green revolution in the late 1960s and 1970s but it is now investments in agricultural research education and rural roads that are the three most effective public spending items in promoting agricultural growth and reducing poverty

habit formation in consumer preferences evidence from panel data this paper tests for the presence of habit formation using household data a simple model of habit formation implies a condition relating the strength of habits to the evolution of consumption over time when the condition is estimated with food consumption data from the panel study on income dynamics the results yield no evidence of habit formation at the annual frequency this finding is robust to a number of changes in the specification it also holds for several proxies for nondurables and services consumption created by combining psid variables with weights estimated from consumer expenditure survey data

policies to move from stabilization to growth although some discussions of stabilization see growth as more or less an assured product of appropriate stabilization this paper argues that there is no guarantee that stabilization will lead to growth it may result in stagnation the paper discusses the essentials of stabilization including inflation targets fiscal policy monetary policy exchange rates and incomes policy and suggests that two areas of structural reform deregulation including trade reform and reform of the financial sector can play a central role in the long run success of a stabilization effort the paper concludes that countries that have experienced protracted high inflation financial instability and payments crises probably will have a difficult and protracted transition to growth and that external resources will be necessary as a continuing feature of the transition sustained external support in the form of long term loans heavily conditioned on the tangibility and credibility of domestic progress in adjustment will help provide a bridge by which flight capital may return and foreign direct investment may be encouraged to take advantage of fresh opportunities

empirical estimates of inflation tax laffer surfaces a 30 country study abstract long run or steady state inflation tax laffer surfaces are estimated with annual data over the 1960s through early 1990s for a varied group of 30 countries using the cagan semi elastic demand for currency and for deposits the model includes an explicit role for the reserve ratio variations in which are shown to be important in explaining inflation tax revenue statistically countries inflation and reserve ratio management are examined in terms of where they operated with respect to steady state laffer boundaries defined as the locus of instruments inflation and reserve ratio that maximize the inflation tax analysis is performed both in terms of sample means of the instruments and their annual values each approach requiring a different conceptual framework few countries operated frequently on the wrong side of the laffer surface

time consistent collection of optimal seigniorage a unifying framework this paper reviews the existing literature on the time consistency problem of seigniorage collection when monetary policy is determined by optimal taxation considerations it develops a unifying accounting framework and suggests a general measure for seigniorage which encompasses the standard measures employed in the literature in addition the ex ante optimal solution to the optimal taxation problem is derived and interpreted in relation to the ramsey principle we show that the different recommendations of the public finance literature i e the friedman rule of optimal deflation moderately positive inflation and seigniorage maximizing inflation are specific solutions to the optimal taxation problem the paper continues with a formal illustration of the time consistency problem of the ex ante optimal policy and the characterization of the time consistent solution under discretion as possible solutions to the time consistency problem we consider reputational forces institutional reforms that establish central bank independence and specific ways of asset and debt management in particular it is formally shown that a modified version of the asset and debt management scheme suggested by persson persson and svensson is not only necessary but also sufficient for optimality although this did not hold in their model

rule of thumb consumers productivity and hours in this paper we study the transmission mechanism of productivity shocks in a model with rule of thumb consumers in the literature this nancial friction has been studied only with reference to scal shocks we show that the presence of rule of thumb consumers is also very helpful in accounting for recent empirical evidence on productivity shocks rule of thumb agents together with nominal and real rigidities play an important role in reproducing the negative response of hours and the delayed responses of output and

international evidence on sticky consumption growth abstract this paper estimates the degree of stickiness in aggregate consumption growth sometimes interpreted as reflecting consumption habits for thirteen advanced economies we find that after controlling for measurement error consumption growth has a high degree of autocorrelation with a stickiness parameter of about 0 7 on average across countries the sticky consumption growth model outperforms the random walk model of hall 1978 and typically fits the data better than the popular mankiw 1989 model though in a few countries the sticky consumption growth and campbell mankiw models work about equally well

foreign aid and market liberalizing reform market oriented economic policies reflected in limited economic activity by government protection of private property rights sound monetary policy outward orientation regarding trade and efficient tax and regulatory policy have been strongly linked to faster rates of economic growth foreign aid is often provided in the belief that it encourages liberalizing reforms in these areas this paper analyzes the impact of aid on market liberalizing policy reform correcting for the possible endogeneity of aid results indicate that higher aid slowed reform over the 1980 2000 period as measured by a broad index of policies disaggregating policy into five areas aid is significantly linked to slower reform in some policy areas but not in others disaggregating by decade aid s adverse impact on policy reform is much more pronounced for the 1980s than for the 1990s

fiscal reforms and stabilisation four hyperinflation cases examined this paper discusses a hypothesis that is common to several recent explanations for the needs of hyperinflations of the 1920s namely that fiscal reforms had been responsible for their sudden end it is suggested that the very presence of these reforms can be disputed once evidence is provided on the fact that budget deficits were mostly caused by the so called oliveira tanzi effect i e deficits were mostly generated by inflation itself some observations are offered on other issues to be addressed if an alternative explanation for the stabilizations are to be found copyright 1990 by royal economic society

the predictability of aggregate consumption growth in oecd countries a panel data analysis we examine aggregate consumption growth predictability we derive a dynamic consumption equation which encompasses relevant predictability factors habit formation intertemporal substitution current income consumption and non separabilities between private consumption and both hours worked and government consumption we estimate this equation for a panel of 15 oecd countries over the period 1972 2007 taking into account parameter heterogeneity endogeneity and error cross sectional dependence using a gmm version of the common correlated effects mean group estimator small sample properties are demonstrated using monte carlo simulations the estimation results support income growth as the only variable with significant predictive power for aggregate consumption growth

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

public sector price controls and electoral cycles public enterprise prices are important policy instruments in developing economies this is why public sector price polices constitute a key element of stabilization programmes implemented in these economies however this significance is not specific to stabilization episodes first this study questions whether an opportunistic politician can manipulate public prices to win elections it analyses the impact of such price controls on budget deficits and the repercussions of alternative financing mechanisms of these deficits on the inflation rate and voters behaviour it is shown that electoral inflation cycles are obtained under domestic debt financing whereas money financing does not permit such a manipulative policy second by focusing on data of the turkish economy for the 1987 1 2003 12 period empirical evidence for such manipulative policies is given

grain marketing parastatals in asia results from six case studies summary using case studies from six asian countries this paper assesses the relevance of underlying rationales for public intervention in food grain markets documents the existing policies and regulatory supports to grain marketing parastatals examines benefits and costs of parastatals and summarizes lessons from reforms and reduced interventions the results suggest that commonly cited rationales for food market intervention are no longer convincing the costs of parastatals led price stabilization are staggering and the price policies are being dictated by special interests the evidences from the early reformers indicate that reduced intervention can promote competition reduce subsidies and release funds for development and anti poverty programs all without jeopardizing price stability

seigniorage old and new policy issues introduction abstract seigniorage is at the crossroad of many avenues of research a summary survey of older and more recent developments from the static allocative approach in the differential taxation framework to policy analyses of the effects of joining the ems for high deficit countries shows that there may be some disorderly traffic and that definite policy conclusions can hardly be drawn from models which so often neglect relevant markets and variables and in particular the financial sectors and financial assets

saving and liquidity constraints this paper is concerned with the theory of saving when consumers are not permitted to borrow and with the ability of such a theory to account for some of the stylized facts of saving behavior the models presented in the paper seem to account for important aspects of reality that are not explained by traditional life cycle models copyright 1991 by the econometric society

on a simple rule for the optimal inflation rate in second best taxation abstract the optimal inflation rate is analyzed in the framework of dynamic second best with endogenous factor prices it is shown that when the marginal excess burden of taxation is relatively small the optimal inflation rate is approximated by a simple rule the paper also analyzes the robustness of this rule to the specification of the model money as an input in utility or production

the dynamics of optimal gradual stabilizations inflation inertia may be quite tenacious because of the simultaneous interaction between policy actions and inflationary expectations under imperfect credibility this result is particularly relevant for understanding some of the failed efforts to stabilize inflation in south america this article deals with the issue of inertia in the framework of imperfect information about the type of the policymaker and extends the existing models to an infinite horizon because policymakers do not have perfect control of inflation a frivolous stabilizer may deviate from the policies of a serious stabilizer without necessarily being unmasked immediately when the difference in the ability of strong and weak policymakers to control inflation is large unexpected inflation may be persistently negative for quite a while thus causing reduced economic activity and giving the indication that credibility is low if the policymaker persists with the stabilization this pattern gradually disappears as his reputation rises but before this final stage the serious policymaker has to compromise his inflation objective in view of adverse expectation about this type and pay the cost of imperfect credibility

liquidity constraints and the substitutability between private and government consumption the role of military and non military spending i introduction using data for a number of economies we investigate i the relationship between private consumption and two types of government spending military and non military and ii the severity of liquidity constraints because of their importance for macroeconomic modeling in theory and practice 1 both issues have been the subjects of considerable theoretical and empirical investigation on the issue of liquidity constraints the most influential research has relied on hall s 1978 euler equation approach to the permanent income hypothesis in an attempt to reconcile hall s and flavin s 1981 methodologies hayashi 1982 modified hall s martingale result to allow for the possibility that a subset of consumers are liquidity constrained and showed that liquidity constraints can result in consumption s excess sensitivity to current income campbell and mankiw 1989 1990 1991 and jappelli and pagano 1989 have applied hayashi s methodology using data from the u s and several other oecd countries on the substitutability issue aschauer 1985 has modified hall s euler equation to allow for substitutability between government spending and private consumption and found that the two are substitutes for the u s karras 1994 however using a similar approach and data for 30 countries concludes that private and government consumption are better described as complementary or unrelated liquidity constraints and substitutability have been combined in studies by graham and himarios 1991 cushing 1992 and graham 1993 using u s data and by evans and karras 1996 for a number of countries a crucial limitation of most of these studies is the use of aggregate government consumption data which counterintuitively imposes a common substitutability parameter on all components of government spending 2 using recently available time series data for a large number of countries the present paper relaxes this restriction by decomposing government consumption into military and non military components enabling us to separately identify their relationship to private consumption the allocation of government consumption between military and non military functions has varied greatly across countries the appendix reports the average size of military and non military government shares in gdp as well as the military non military ratio by country over the 1970 1989 period average military expenditure as a fraction of gdp for example has ranged in our sample from 0 11 in mexico to 12 30 in jordan similarly the fraction of government consumption absorbed by military expenditure has ranged from 1 09 in mauritius to 66 82 in poland this sizable variability is promising in terms of cross sectional identification power but it also suggests that the estimated parameters must not be assumed to be common across countries the estimated model is derived in section ii which combines liquidity constraints and substitutability by nesting the approaches of hayashi 1982 and aschauer 1985 in the same section we discuss data sources and the estimation strategy which permits the estimated parameters to vary by country in a way that helps determine how they are influenced by country specific factors section iii estimates the model for a panel of the 66 countries for which annual data on all series are available for the 1970 1989 period the paper s main conclusions are given in section iv ii methodology and data we assume that consumers in economy i at time t derive utility from effective consumption c sup which we define as 1 mathematical expression omitted where c is private consumption g sup m and g sup nm are the military and non military components of government consumption the parameters theta sup m and theta sup nm measure the degree of substitutability between c and g sup m and c and g sup nm respectively

seigniorage and inflation the case of argentina this paper studies the relation between seigniorage and inflation in argentina for the period 1979 1989 we estimate a money demand function and derive the laffer curve for several sub periods with different monetary exchange rate regimes we find that for most of the period the argentine economy remained on the efficient side of the laffer curve the long run revenue maximizing rate of inflation has been around 20 percent per month for the tablita 1979 1981 and post austral 1985 1988 periods and around 30 percent per month for the pre austral period 1982 1985 the long run maximum level of seigniorage has been above 6 percent of gdp our results imply that the hyperinflation experienced by argentina in 1989 can be interpreted as an unstable phenomenon that resulted from the need to collect a level of seigniorage that exceeded the maximum warranted by the demand for money copyright 1995 by ohio state university press

does buffer stock saving explain the smoothness and excess sensitivity of consumption one of the lasting contributions to modernday consumer theory is the idea that consumption is determined by the expected value of lifetime resources or permanent income the modern day specification of this concept is typically presented as a special case of intertemporalchoice theory where felicity functions are quadratic labor income is stochastic there are no restrictions on borrowing consumers have infinite horizons and expectations are formed rationally we refer to this model as the permanentincome hypothesis pih although the pih has considerable intuitive appeal a series of influential papers published after its inception revealed two notable discrepancies between the model s predictions and aggregate data first the model predicts that consumption growth should be more volatile than income growth if aggregate income growth has positive serial correlation as the quarterly data suggest it does yet aggregate consumption growth is in fact much smoother than aggregate income growth angus deaton 1987 john y campbell and deaton 1989 jordi gali 1991 second the pih predicts that consumption changes should be orthogonal to predictable or lagged income changes yet the coffelation between consumption growth and lagged income growth has been found to be one of the most robust features of aggregate data for example marjorie a flavin 1981 alan s blinder and deaton 1985 campbell and n gregory mankiw 1989 orazio p attanasio and guglielmo weber 1993 thus aggregate consumption growth has been described as exhibiting two puzzles it is both excessively smooth relative to current labor income growth and excessively sensitive to lagged labor income growth 2 in response to these and other empirical anomalies researchers have recently sought out modifications of the pih framework chief ludvigson federal reserve bank of new york 33 liberty street new york ny 10045 michaelides university of cyprus p o box 20537 1678 nicosia cyprus a previous version of this paper appeared under the title can we explain the consumption excesses yet aggregate consumption implications of buffer stock saving behavior for many helpful comments we thank orazio attanasio dave backus ben bernanke john y campbell christopher carroll todd clark angus deaton pierreolivier gourinchas bo honore james kahn martin lettau costas meghir christina paxson steve pischke andrew samwick christopher sims mark watson guglielmo weber michael woodford steve zeldes and two anonymous referees conference participants at the national bureau of economic research summer workshop on the aggregate implications of microeconomic consumption behavior july 1998 the tmr workshop on saving and pensions center tilburg university march 1999 and the new york area macroeconomics workshop october 1998 seminar participants at columbia university insead the new york federal reserve university college london london business school city university business school university of cyprus tel aviv university and jeffrey brown for excellent research assistance the views expressed are those of the authors and do not necessarily reflect those of the federal reserve bank of new york or the federal reserve system any errors or omissions are the responsibility of the authors 1 note that the important insight of danny quah 1990 that individuals may be better able than econometricians to distinguish short run from long run innovations to their income cannot resolve the excess smoothness puzzle laid out in campbell and deaton 1989 these authors show that in the context of the pih excess sensitivity and excess smoothness are the same phenomena in addition campbell 1987 demonstrates that superior information of the type emphasized by quah will show up in households saving behavior and using this information allows the econometrician to control for the agent s private information when predicting income since excess sensitivity is well established and controlling for saving does not eliminate it see campbell and deaton 1989 the observed smoothness of consumption cannot be explained by superior information on the part of permanent income consumers see deaton 1992 for further discussion 2 philippe bacchetta and stefan gerlach 1997 and ludvigson 1999 document another kind of excess sensitivity the correlation between consumption growth and predictable changes in consumer credit although we do not explore these findings here ludvigson finds that a bufferstock model with time varying liquidity constraints can replicate such a correlation

returns to investment in less favored areas in developing countries a synthesis of evidence and implications for africa abstract a large proportion of world s population lives in marginal or less favored areas these areas are of home to the poorest segment of the population particularly in rural areas in the past government has targeted their resources mostly to the high potential or irrigated areas these investments have generated rapid growth in agricultural production for example the so called green revolution in south and southeast asia in the 1970s and 1980s which in turn has helped to alleviate rural and urban poverty however as investments continue to increase in these favored areas their marginal returns have begun to decline and environmental problems are emerging evidence shows that it is in the marginal areas or less favored areas where many investments may have higher returns today these investments may have even larger impacts on poverty reduction and environmental protection as poor people are increasingly concentrated in the marginal areas where natural resources have already been severely degraded this study synthesizes some recent studies from india and china on the relative returns to investments in favored and less favored areas and presents some preliminary evidence from uganda and offers some policy implications for africa on how governments and international donors can reprioritize their investment portfolio in order to achieve multiple goals of growth poverty reduction and environmental protection

modern input promotion in sub saharan africa insights from asian green revolution using case materials from four major cereal growing countries in asia bangladesh india indonesia and pakistan the article analyzes key aspects of agricultural input policies in asia results suggest that asian policies differ from the current wave of african input subsidy programs in three important ways i instead of focusing mostly on seed and chemical fertilizer input promotion in asia involved a package approach involving investments in agricultural rd ii farmers in three of four countries paid higher prices net taxed for fertilizer during the height of the green revolution suggesting that it was the profitability not the subsidy that was central to increasing fertilizer use and iii asian countries did not target input subsidies but given leakage and diversion estimates of targeted programs it is unclear whether targeting would have been more cost effective both continents have two challenges in common degradation of soil health and increasingly larger shares of public spending on input subsidies the first challenge calls for paying attentions to improving fertilizer use efficiency which is an achievable target with high pay off in the long run the other challenge is now a historical fact that is once introduced subsidies are hard to eliminate even if they no longer contribute to agricultural productivity growth

toward a green revolution in africa what would it achieve and what would it require the current global food crisis has reemphasized the costliness of africa s failure to achieve food security and poverty reduction the instrument by which other more successful developing countries achieved these outcomes was a green revolution in agriculture while previous research has provided largely discursive appraisals of the viability of an african green revolution this article adopts a more rigorous methodology to address that question first an economy wide multimarket model augmented with existing poverty growth elasticities is developed to assess the likely impacts of a rapid acceleration in food production of the kind witnessed in previous green revolutions on food prices consumption and demand farmer revenue and poverty our results suggest that a rapid growth in staple production together with more integrated regional markets would reduce food prices by roughly 20 40 for consumers and 10 20 for producers among the major crops this translates into a large rise in farm revenues annual agricultural growth rates of 6 5 or higher broader income growth and food security and over 70 million africans being lifted out of poverty the article concludes by emphasizing the kinds of fundamental policy actions and resources that would be required for achieving these outcomes

zimbabwe s maize based green revolution preconditions for replication abstract the green revolution was launched in 1960 in zimbabwe five years before it got underway in india since zimbabwe s green revolution was spearheaded by white commercial farmers however it was ignored by africa s new leaders in the 1960s as they experimented with state farms from moscow communal farms from china and land settlement schemes from israel at zimbabwe s independence in 1980 the new majority ruled government introduced a number of programs to help smallholders increase food and cash crop production drawing on a backlog of hybrid maize varieties expanded access to credit higher guaranteed government maize prices and marketing subsidies smallholders doubled maize production during 1980 1986 zimbabwe s maize based green revolution challenges those who allege that hybrid maize cannot compete with sorghum in low rainfall areas and that it is unsuitable for resource poor farmers because of the need to purchase new seed each year today virtually 100 of zimbabwe s maize area is under hybrids and short season hybrids are outcompeting other foodgrains in many low rainfall areas zimbabwe s biggest challenge is to develop cost effective marketing policies and institutions to sustain its maize based green revolution countries trying to replicate zimbabwe s success story should focus on fulfilling four interrelated preconditions political technological economic and institutional

inflationary rigidities and orthodox stabilization policies lessons from latin america orthodox stabilization programs in latin american countries have been notoriously unsuccessful in combating inflation despite the imposition of stringent cuts in government deficits in most cases inflation came down only slowly and temporarily with concomitant declines in growth and employment the bolivian program one of the only latin american successes is contrasted with those of argentina brazil chile and mexico the problems of dealing with chronic inflation are compared with those of hyperinflationary countries and the influence of price and wage rigidities expectations and credibility is explored the study shows that fiscal restraint is a necessary but not sufficient condition for success and that sound management of nominal variables the exchange rate and money supply are also necessary the critical role of credibility is linked with price and wage rigidities in the chronic inflation countries whereas the unsuitability of hyperinflation is seen to increase the credibility of and thus the potential for successful stabilization programs

dollarization in post hyperinflationary argentina abstract this paper analyzes the continued dollarization of the argentine economy which experienced a rapid decline in inflation following its hyperinflations of the 1980s first a measure of dollar currency circulating in argentina is developed thereby improving upon previous studies of dollarization and currency substitution that focused on dollar deposit holdings only second cointegration analysis of peso money demand in argentina finds a negative ratchet effect from inflation the reduction in peso money demand attributable to the ratchet mirrors the estimated stock of all dollar assets held domestically by argentine residents consistent with the hypothesis of irreversible dollarization

optimal inflation rates a generalization note in his classic article the welfare cost of inflationary finance 1956 bailey indicted the use of the printing presses to raise resources on the grounds that the average ratio of the welfare cost to the revenue becomes excessive at moderate rates of inflation he generalized these results to a competitive banking system paying interest on its deposits but subject to a sterile legal reserve requirement any single bank would be forced by competition to pay interest on its deposits equal to the yield on its assets times l f wheret is the legal reserve ratio the opportunity cost of holding deposits is then the return on assets minus the yield on deposits which in turn is equal to the yield on assets timest bailey assumed the real rate was zero not a crucial assumption and that at high enough rates of inflation no one would use currency so that all money would be held as interest bearing deposits 1 the opportunity cost of holding deposits would then be the actual and anticipated rate of inflation tr times the reserve ratio while the seignorage accruing to the authorities would be trfm p the return on assets 7rm p multiplied by the ratio of high powered money to the money supply bailey showed that to get the same tax revenue as in a pure currency system t 1 the authorities must inflate at a much higher rate namely the rate of inflation whent 1 times the reciprocal of the reserve ratio r l t a reduction in the reserve ratio raises the inflation rate needed to command the same resources a proposition rediscovered by calvo and fernandez 1983 a1

reserve requirements and optimal seigniorage abstract this note presents a model of optimizing agents who chose to hold deposits at financial intermediaries which are required to hold fractional reserves of fiat money when the stock of fiat money is expanded the reserve requirement functions as a tax on deposits the combination of reserve requirements and inflation results in a lower steady state utility than a direct tax on deposits the optimal monetary policy when reserves are required is to minimize reserve requirements and inflate without limit the stock of fiat money

high inflation heterodox stabilization and fiscal policy abstract in 1985 86 argentina bolivia brazil and israel introduced stabilization programs aimed at drastic and immediate reductions in inflation besides traditional fiscal and monetary policies the stabilization packages included a number of heterodox elements such as wage and price freezes exchange rate pegging and deindexation measures this paper delineates the analytical relationship between the traditional and heterodox policies discusses the role and impact of the heterodox policies in the programs and examines in detail the role of traditional fiscal policy when coupled with heterodox policies and applied with the aim of moving quickly from very high to very low inflation

inflation unemployment and distributional conflict in argentina 1984 90 the cycle of various economic stabilisation efforts in argentina during the 1980s has often been characterised as reflecting either policy confusion on the part of officials or their unwillingness to depart from an obsolete model of economic development hence according to some the alternation between orthodox and heterodox policy approaches has revealed an absence of either economic policy wisdom or political conviction less attention has been paid to the underlying real class based conflict for income that has manifested itself in terms of high rates of inflation and at times hyperinflation interpreting the issue from this perspective allows us to appreciate the essential continuity of the process of neo liberal reform of the argentine political economy that commenced with the post peronist military coup in 1976 and has more recently culminated with the rise of the nominally peronist regime of carlos menem

competitive banks and the inflation tax abstract the purpose of this note is to show that the presence of a competitive banking sector has important quantitative implications for the revenue maximizing rate of inflation

individual income incomplete information and aggregate consumption individual income is much more variable than aggregate per capita income i argue that aggregate information is therefore not very important for individual consumption decisions and study models of life cycle consumption in which individuals react optimally to their own income process but have incomplete or no information on economy wide variables since individual income is less persistent than aggregate income consumers will react too little to aggregate income variation aggregate consumption will be excessively smooth since aggregate information is slowly incorporated into consumption aggregate consumption will be autocorrelated and correlated with lagged income on the other hand the model has the same prediction for micro data as the standard permanent income model the second part of the paper provides empirical evidence on individual and aggregate income processes different models for individual income are fit to quarterly data from the survey of income and program participation making various adjustments for measurement error calibrating the consumption model using the estimated parameters for the income process yields predictions which qualitatively correspond to the empirical findings for aggregate consumption but do not match them well in magnitude

india s grain security policy in the era of high food prices a computable general equilibrium analysis this study uses a computable general equilibrium model to evaluate the fiscal and welfare costs of the market stabilisation and insulating food policy of india during the 2007 08 global food crisis we demonstrate that domestic food grain price stabilisation through simultaneously subsidising consumers and producers and restricting exports entailed huge fiscal costs and equally large welfare costs to india an outcome that is almost always the worst as compared to the alternative policy mixes examined in this study while the most market oriented domestic and trade policy alternatives that would generate better welfare effects and the least fiscal costs may not be feasible due to political economy considerations we argue that there exist some middle ground policy mixes featuring partial relaxations of domestic subsidies on either food grains or fertilisers and or less restrictive border policies which are superior in terms of their welfare effects and fiscal costs and might also be politically feasible these findings have important implications on the ongoing debates on india s food security policy particularly in relation to the discussion on its national food security act

fertilizer subsidies and food self sufficiency in indonesia indonesia is a net importer of almost all of its staple foods national self sufficiency in food especially the main staple rice is a core objective of economic policy poverty reduction is also a core policy objective since the 1970s indonesia has used agricultural input subsidies especially on fertilizer to stimulate agricultural production largely in pursuit of the goal of rice self sufficiency more recently it has also used output protection especially in rice for the same purpose this article utilizes a multisectoral multihousehold general equilibrium model of the indonesian economy to study the trade offs between the goals of self sufficiency and poverty reduction when two alternative means are used to achieve them a fertilizer subsidy on the one hand and output protection on the other it does this by analyzing the aggregate and distributional effects of these two sets of policies and by comparing their effects with nonintervention the analysis shows that in terms of its effects on poverty a fertilizer subsidy can be a more effective instrument for achieving the goal of rice self sufficiency than final product import restrictions

making sense of a crank case monetary diversity in argentina 1999 2003 based on empirical data this study discusses the introduction acceptance and circulation of two complementary currencies in argentina that do not fit well in the main approaches to the nature of money these two monetary circuits provincial and community currencies were introduced as units of account to denominate the value of debt and circulated as means of payment to overcome monetary stringency during the crisis of 1999 2003 after discussing several theories on the nature of money we reflect on the institutional significance of currency circuits as concurrent and rather stable pairs of trade and money we suggest that several theories of money need to be combined to account for the variety and heterogeneity of daily monetary practices in a broad spectrum of countries

consumption and credit constraints international evidence abstract if some consumers are liquidity constrained aggregate consumption should be excessively sensitive to credit conditions as well as to income moreover the excess sensitivity may vary over time using data for the united states canada the united kingdom japan and france we find a substantial impact of credit aggregates on consumption in all countries considered moreover the borrowing lending wedge is a significant determinant of consumption in the united states canada and japan using extended kalman filtering techniques we show that the excess sensitivity varies over time with a clear tendency to decline in the united states

heterogeneous returns to chemical fertilizer at the intensive margins insights from nepal increased fertilizer use is considered important for agricultural development in low income countries promoting increased use of chemical fertilizer by lowering its price may be ineffective if demand is price inelastic in theory the price elasticity of demand depends on the returns to its use but the evidence is scarce furthermore while returns are often estimated for small changes in chemical fertilizer use returns to larger changes in its use intensive margins are less understood through the inter zonal comparisons in nepal we provide indicative evidence that greater returns to chemical fertilizer are associated with greater price elasticities of demand moreover the evidence suggests that returns at the intensive margins rather than returns to small changes may largely account for inter zonal differences in returns to chemical fertilizer within nepal the results suggest that better understanding the returns at the intensive margins is critical for effective agricultural inputs policies in developing countries

inflation in argentina stop and go since the austral plan the austral plan launched in 1985 was argentina s most recent stabilization strategy for reducing high inflation a heterodox program it combined orthodox components tight fiscal policy and monetary restraint with less conventional wage and price controls the austral plan failed to bring inflation down on a sustained basis but it provided useful lessons about the design of heterodox stabilization programs the difficulties of sustaining this type of effort and the consequences of failure

the permanent income hypothesis and consumption durability analysis based on japanese panel data the permanent income hypothesis with durability of commodities is tested on a panel of about 2 000 japanese households for several commodity groups under static expectations about real interest rates and for some class of utility functions consumption which is a distributed lag function of current and past expenditure follows a martingale main empirical results are i the durability of commodities usually classified as services is substantial ii the hypothesis applies to about 85 percent of the population consisting of wage earners and iii income changes explain only a small fraction of the movements in expenditure

public sector price increases credibility and welfare abstract this paper examines the dynamics of inflation and unemployment when the government increases public sector prices and wage indexation prevents the labor market from clearing in the short run credible reforms are virtually certain to be immediately deflationary and welfare improving even when the labor market clears very slowly temporary price increases however usually produce higher inflation after a short period of time and often reduce welfare when higher inflation provokes the government to reverse the reform there exist multiple self fulfilling equilibria

exchange rate based stabilisation durables consumption and the stylised facts in this article we show that a model featuring durable consumer goods imperfect substitution between domestic and foreign assets and weak credibility can explain the qualitative and quantitative aspects of the stylised facts associated with exchange rate based stabilisation including the tremendous increase in real interest rates following a temporary reduction in the crawl total consumption spending rises 14 26 the real exchange rate appreciates 20 37 and the current account deficit swells to 10 15 of gross domestic product despite large capital inflows the real interest rate increases from 10 to 20 100
