the hyperinflation model of money demand revisited in this paper we propose a test of the hyperinflation model of money demand which is valid under any assumption concerning agents expectations subject only to the restriction that forecasting errors are stationary it is also demonstrated that highly efficient parameter estimates can be obtained and restrictions on them tested under the same weak assumption finally it is shown how these first stage estimates can be utilized to test the stronger assumption of rational expectations the arguments are illustrated by analysis of the classic data on european hyperinflations previously analyzed by cagan 1956 barro 1970 and abel dornbusch huizinga and marcus 1979 copyright 1991 by ohio state university press

the effect of regime shifts on the long run relationships for swedish money demand when the possibility of an unknown structural break is allowed and it is taken into account we find a significant long run relationship between swedish money demand and its determinants that is not found when no break is considered the estimated elasticities show that money demand is more responsive to its determinants in the period after the break than before possible underlying reasons for the occurrence of this break and its implications are explained

human capital and the risk of divorce an asset in search of a property right the new home economics 2 5 6 7 analyzes investments in human capital or children in terms of a model of household decision making traditionally a harmony of interests between the spouses is assumed to prevail and this is formalized by postulating a household utility function 9 or by assuming the maximization of the joint income of the husband and wife 6 recently the approach has been modified to admit the potential for marital disharmony 3 4 the present paper follows this lead and considers how family investments in each partner s human capital is conditioned by the risk of divorce the focus on human capital rather than say tangible capital is of particular interest because of this asset s illiquidity and the fact that the courts have generally not recognized the property rights of one spouse in the human capital acquired by the other during the marriage it demonstrates that the absence of property rights generally produces a sub optimal pattern of human capital investment specifically the risk of divorce leads to overinvestment in human capital with this outcome being more likely the greater the fragility of the marital relationship

modelling inflation in georgia the article explains the behaviour of inflation in georgia in the post stabilization period long run equation linking prices with money and exchange rate as well as short run dynamic equation for inflation are estimated the inflation equation is stable points to a dominant role of exchange rate in the inflation behaviour the equation explains well the behaviour of inflation after the russian crises when inflation increased sharply but was quickly brought under control when the national bank of georgia kept its monetary policy tight and exchange rate stable

money demand the cagan model and the inflation tax some latin american evidence this paper examines the demand for money under conditions of very high inflation in argentina bolivia brazil chi le and peru during the 1970s and 1980s the authors test whether the monetary and inflationary experiences of these countries can be adequately characterized by the cagan 1956 model using an econometric procedure that is not reliant on any particular assumpti on concerning expectations formation except that forecasting errors are stationary the authors also examine the importance of foreign asset substitution in domestic portfolios and the hypothesis that monetary policy was tantamount to maximization of the inflation tax revenue before testing the rational expectations hypothesis copyright 1993 by mit press

modeling and forecasting tourism demand for arrivals with stochastic nonstationary seasonality and intervention abstract this paper presents the use of time series sarima and marima with interventions in forecasting tourism demand using ten arrival series for hong kong augmented dickey fuller tests indicated that all the series were seasonal nonstationary significant interventions such as relaxation of the issuance of out bound visitors visas the asian financial crisis the handover and the bird flu epidemic were all empirically identified with significant test results and expected signs the forecasts obtained using models that capture stochastic nonstationary seasonality and interventions sarima and marima with intervention analysis are compared with other eight time series models and were found to have the highest accuracy

money demand and exchange rate determination under hyperinflation conceptual issues and evidence from yugoslavia a modified monetary model of exchange rate determination is advanced and tested for the yugoslav hyperinflation of 1992 94 stating that the exchange rate is determined directly in the money market thus implying that private agents due to dollarization denominate their real money holdings in foreign currency empirical evidence supports the advanced model apart from the last seven months of the yugoslav hyperinflation the exact re present value model of the exchange rate is accepted while that of the price level is rejected for the whole period of hyperinflation the modified money demand schedule with money holdings denominated in foreign currency is nonlinear with decreasing semielasticity of money demand

wood extraction among the households of zege peninsula northern ethiopia abstract the dependence of smallholder farmers on forest resources for their sustenance and livelihoods is a major driver of deforestation and degradation of forest resources in tropical countries understanding the socio economic drivers that aggravate the extraction and overexploitation of forest products is vital for designing effective forest conservation and restoration measures this particularly holds with regard to the importance of two fundamentally opposing motivations of smallholder forest exploitation which we label wood extraction for need vs wood extraction for greed this study was conducted at zege peninsula in northern ethiopia to investigate the factors affecting the extraction and marketing of wood from the peninsula s primary dry afromontane forest by smallholders data was collected using household survey focus groups discussions and key informant interviews data analysis employed the heckman two steps econometric model the predominant involvement of vulnerable households in forest exploitation suggests that wood extraction was driven by need and mainly served sustenance and safety net functions in addition we also found evidence of greed driven forest exploitation as a consequence of selective rule enforcement and nepotism the forest enforcement committee was not effective in safeguarding the forest there by contributing to increased wood extraction and marketing by community members for income generation this suggests that in order to protect the forest interventions are needed that aim at creating alternative income opportunities for smallholders through improved production of non timber forest products enhanced market access and the provision of locally adapted technologies as well as at increasing the integrity of law enforcement

modeling the demand for narrow money in the united kingdom and the united states abstract despite the importance of well specified empirical money demand functions for inference forecasting and policy problems in modeling have arisen concerning the economic theories of money demand the data institutional frameworks financial innovation and econometric implementation by developing constant data coherent m 1 demand equations for the u k and the u s we investigate these issues and explain such puzzles as missing money the great velocity decline and the recent explosion in m 1 the endogeneity of money the lucas critique and the non invertibility of our m 1 models are also discussed

cointegration tests of the monetary exchange rate model for three high inflation economies tests of cointegration are applied to the monetary model of the exchange rate to determine if the model represents a long run equilibrium relation for three high inflation countries the countries tested are argentina chile and israel each paired with the united states as the base country evidence favorable to cointegration among the variables of the monetary model is found using johansen s maximum likelihood procedure copyright 1994 by ohio state university press

money demand and disinflation in selected ceecs during the accession to the eu a panel data set for six countries czech republic hungary poland romania slovakia and slovenia is used to estimate money demand with panel cointegration methods over the recent disinflation period the basic money demand model is able to convincingly explain the long run dynamics of m2 in the selected countries however money demand is found to have been significantly determined by the euro area interest rates and the exchange rate against the euro which indicates possible instability of money demand functions in the central and eastern european countries therefore direct inflation targeting is an appropriate monetary regime before the eventual adoption of the euro

the demand for m1 in the u s a 1960 1988 estimated u s m1 demand functions appear unstable regularly breaking down over 1960 1988 e g missing money great velocity decline m1 explosion we propose a money demand function whose arguments include inflation real income long term bond yield and risk t bill interest rates and learning curve weighted yields on newly introduced instruments in m1 and non transactions m2 the model is estimated in dynamic error correction form it is constant and with an equation standard error of 0 4 variance dominates most previous models estimating alternative specifications explains earlier breakdowns showing the model s distinctive features to be important in accounting for the data

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

the german hyperinflation and the demand for money revisited this paper shows that a remarkably well defined demand for real balances exists for the german hyperinflation episode including the final months which have previously been considered as outliers the authors econometric analysis exploits the theory of cointegration given the obvious nonstationarity of the data further they consider two likely sources of misspecification income variability and the necessity to distinguish between the high inflation and hyperinflation episodes copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

cointegration and cagan s model of hyperinflation under rational expectations when money and prices are integrated of order two philip cagan s 1956 model of hyperinflation will give rise to two different levels of cointegration in most of the literature on the german hyperinflation one of these cointegrating relationships has been ruled out a priori by assuming that velocity shocks follow a random walk using data from the german hyperinflation the author finds this assumption to be unjustified based on a straightforward extension of the cointegrated var approach suggested by john y campbell and robert j shiller 1987 a method to evaluate the cagan model under rational expectations and no bubbles is proposed and implemented to the german data copyright 1993 by ohio state university press

credibility of a new monetary regime the currency board in bulgaria abstract low credibility reflected in persistent expectations of high inflation is the usual suspect in costly disinflation efforts a currency board is a monetary regime that attempts to establish credibility by reducing uncertainty regarding the inflation preferences of the policymaker and the environment in which the policymaker operates this paper uses unique survey data from bulgaria and finds that expected inflation is indeed lowered by the prospect of a currency board but to a different degree for different agents priors of the type of the policymaker and familiarity with the operation of the currency board contribute to explaining the differences

economic policies and demand for money evidence from canada this study identifies canadian fiscal and monetary policy regime changes that could influence the services of money it is argued that if these policy regime changes were not incorporated in the estimation of demand for real balances the resulting estimate would be biased and unstable using canadian monthly data for the january 1975 to june 2001 period the paper estimates a standard demand for money m1 function with and without these policy regime changes it was found the demand for money in canada is stable over the short and long run periods when these policy regime changes are incorporated and the estimated coefficients have correct signs

cointegration and unit roots this paper provides an updated survey of a burgeoning literature on testing estimation and model specification in the presence of integrated variables integrated variables are a specific class of non stationary variables which seem to characterise faithfully the properties of many macroeconomic time series the analysis of cointegration develops out of the existence of unit roots and offers a generic route to test the validity of the equilibrium predictions of economic theories special emphasis is put on the empirical researcher s point of view

the demand for money in argentina 1978 1987 before and after the austral program in this study a monthly money demand function for argentina is estimated for a period that ends one month before the austral program may 1985 the performance of the traditional econometric approach is compared with the new cointegration approach to time series econometrics the comparison is carried out by a postsample forecast of the demand for money for a period of two years after the stabilization until july 1987 the cointegration approach is found superior to the traditional approach the first produces a relatively stable money demand whereas the second yields an unstable one

forecasting tourism demand with arma based methods abstract the forecast of tourism volume in the form of arrivals is of special importance for tourism and other hospitality industries because it is an indicator of future demand thereby providing basic information for subsequent planning and policy making in this paper three univariate arma based models are applied to tourism demand as represented by the number of world wide visitors to hong kong japan korea taiwan singapore thailand the philippines australia and new zealand the study employs both monthly and quarterly time series generated from nine principal tourist destinations in asian pacific region in the forecasting exercise to ensure the reliability of the forecasting evaluation forecasting performance based on disaggregated arrival series in a particular destination is examined as well the general impression is that the arma based models perform very well and in some cases the magnitude of mean absolute percentage error is lower than 2 level

money demand during hyperinflation and stabilization bulgaria 1991 2000 the demand for money in bulgaria is estimated over a ten year period 1991 2000 of high inflation and inflation uncertainty the paper distinguishes between three well defined sub periods high variable but not systematically accelerating inflation from 1991 until april 1996 the near hyperinflation period from may 1996 to february 1997 and the subsequent stabilization after the adoption of a currency board the empirical analysis utilizes a standard methodology of cointegration and error correction the functional determinants of the demand for money change during the different sub periods during the hyperinflation episode cagan s model is employed

modelling money demand for a panel of eight transitional economies in this article we estimate money demand functions for a panel of eight transitional economies using quarterly data for the period 1995 01 1995 to 2005 03 we find that real m1 and real m2 and their determinants namely real income and short term domestic interest rate are cointegrated both for individual countries as well as for the panel long run elasticities suggest that consistent with theory real income positively and nominal interest rate negatively impact real money demand our test for panel granger causality suggests short run bidirectional causality between m1 and m2 and their determinants finally our tests for stability of the money demand functions reveal more cases of unstable money demand functions when m2 is used as a proxy for money demand

another visit to the cagan model of money demand the latest russian experience abstract this paper investigates empirically the cagan style money demand function for russia during the recent hyperinflation era 1992 1994 using the johansen multivariate cointegration test results indicate that rate of change of exchange rate currency depreciation is required in the demand function for real m2 and real currency in order to obtain a stationary long run relationship error correction model results show that there exists a bidirectional causality between real money balances and determinants of real money demand including currency depreciation exchange rate sensitivity of the demand for money indicates currency substitution

money demand during hyperinflation and stabilization bolivia 1980 1988 i introduction the stability of demand for money equations has been at issue in both econometric research and policy analysis the academic debates about the relative merits of the traditional buffer stock and the error correction models of demand for money have centered on parameter stability 1 in policy discussion the scope for remonetization following stabilization depends on the upward shift in the demand for money and the consequent predictability of higher money demand with lower rates of inflation 2 only an increased demand for money would make further credit expansion non inflationary inflation uncertainty has a pervasive effect in the money price nexus high inflation uncertainty makes money a riskier asset depressing the demand for money on a long term and possibly short term basis this impact on the demand for money means that policies influencing inflation will have an additional effect through their impact on inflation uncertainty as well as on expected inflation this paper examines the role of inflation uncertainty in a dramatic case study bolivia during the 1980s this was a decade of extreme macroeconomic instability annual inflation rates reached over 20 000 percent motivating a subsequent stabilization which drove annual inflation rates down to less than 25 percent where they have remained for more than five years perhaps more than any other country in recent history bolivia has undergone a dramatic structural shift in its macroeconomic policy regime to what extent did the demand for money shift during this period in its sensitivity to expected inflation inflation uncertainty and to underlying monetary disequilibria as the inflation stabilization progressed how fast did the money demand parameters react to this new regime change was there scope for remonetization in bolivia following the now famous stabilization plan of august 1985 the new economic plan introduced by president victor paz estenssoro 3 previous literature on the demand for money has explored the role of inflation uncertainty with ambiguous results 4 klein 1977 observed that inflation rate uncertainty reduced the average and marginal productivity of real cash balances in providing monetary services effectively a greater volume of real cash balances is required to obtain the same quality adjusted level of cash balances while the impact on the demand for money is theoretically uncertain because the income and substitution effects work in opposite directions klein provided empirical evidence that inflation uncertainty measured by a moving five year variance around a moving ten year trend with data from 1880 to 1972 actually increased the demand for money in the united states around the same time boonekamp 1978 presented a two period mean variance model of money and bond demand highlighting the potential importance of a hedging role in the demand for money in the face of inflation uncertainty related to aspects of both of these two approaches and working with a capital asset pricing model capm sweeney 1988 drew on university of michigan survey data on inflationary expectations to resolve the theoretical ambiguity of the impact of inflation uncertainty his results based on post war quarterly u s data contrasted with those of klein by showing a negative impact of inflation uncertainty on money demand in his study of the demand for money in the six hyperinflations originally examined by cagan 1956 khan 1977 measured inflation uncertainty by the absolute value of the change in inflation his model assumed that inflation uncertainty would affect the demand for money not directly but by altering the adaptive expectations parameter in the adjustment of inflation expectations his empirical estimates implied a negative impact of inflation uncertainty on the demand for money during accelerating inflation engle 1982 introduced the concept of arch autoregressive conditional heteroskedastic models with a specific application to inflation expectations

the monetary dynamics of sustained high inflation taiwan 1945 1949 taiwan experienced a sustained period of very high price inflation in the period 1945 1949 which led to an eventual rise in prices even greater than that experienced during some of the classic european hyperinflations analyzed by cagan 3 and others makinen and woodward 22 90 note that on the list of recognized hyperinflations one will not find taiwan but nevertheless argue that this episode should be classed as such although the average rate of taiwanese inflation during this period was not as high as in the episodes examined by cagan the very length of the period during which inflation remained high singles the taiwanese experience out as an extremely interesting period for analysis by monetary economists in this paper a primary aim is to examine whether the salient features of the demand for money during this period can be adequately characterized by an application of cagan s model of money demand under conditions of hyperinflation in particular we apply a test of cagan s model which is not contingent on any particular assumption concerning expectations formation except that agents errors in forecasting inflation are stationary using these first stage estimates we then examine subject only to the same weak assumption of stationary forecasting errors the hypothesis that the monetary authorities expanded the money supply in such a way as to maximize the inflation tax revenue ensuing from money creation finally we test the rational expectations version of the hyperinflation model of money demand the remainder of the paper is set out as follows in section ii we discuss the background to the taiwanese hyperinflation of 1945 1949
