a multivariate cointegrated modelling approach in testing temporal causality between energy consumption real income and prices with an application to two asian ldcs unlike previous studies on the casual relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multiple cointegration tests preceded by various unit root or nonstationarity tests we test for cointegration between total energy consumption real income and price level of two asian ldcs thailand and sri lanka nonrejection of cointegration between variables rules out granger noncausality and implies at least one way of granger causality either unidirectional or bidirectional secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample grangerexogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total

growth and the external constraint lessons from the spanish case the present article attempts to determine the role played by the balance of payments constraint on economic growth in spain 1960 94 using cointegration techniques this empirical exercise also serves to reveal some shortcomings in the usual procedures for estimating thirlwall s law in particular the spanish case reveals how important it is to introduce a variable that expresses the competitiveness gains generated by improvements in quality of the goods and services into the export function it also demonstrates the inadequate simplification entailed in an a priori exclusion of relative prices in external equilibrium equation not taking these two aspects into consideration may give rise to an erroneous confirmation of thirlwall s law especially if as in the spanish case both effects offset each other finally if the aim is to analyse long term relationships between variables it would seem advisable to use procedures such as cointegration with variables in levels

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

units of measurement and the stone index in demand system estimation the stone index typically used in estimating linear almost ideal demand systems is not invariant to changes in units of measurement which may seriously affect the approximation properties of the model a modification to the stone index or use of a regular price index instead are both desirable practices in estimating linear ai models

household food demand in rural china this article explores rural household food consumption behaviour in china using a large household data set from jilin province data are classified into four main food groups grain vegetable products animal products and other foods a household food demand system incorporating four household characteristics is estimated using an la aids model assuming a three stage budgeting procedure expenditure elasticities for a range of food groups are estimated with a particular focus on animal products the inclusion of household characteristics did not have a big impact on the elasticity values in any of the three stages of the budgeting process the total expenditure elasticity for grain stage ii was 0 64 suggesting substantial future growth in household demand for fine grains such as rice and wheat as per capita incomes continue to grow in rural areas the highest conditional and total expenditure elasticity values were for the animal products stage ii group 1 22 and 0 76 respectively within this

stock watson dynamic ols dols and error correction modelling approaches to estimating long and short run elasticities in a demand function new evidence and methodological implications from an application to the demand for coal in mainland china in this paper robust elasticity estimates of coal demand for china are derived using annual data 1953 92 in so doing we illustrate the use of a powerful yet practically convenient and recently developed modelling procedure devised by stock and watson known as dynamic ols dols who provide evidence based on monte carlo simulations of this estimator being superior in small samples compared to a number of alternative estimators as well as being able not only to accommodate higher orders of integration but also to account for possible simultaneity within regressors of a potential demand system furthermore cointegration and error correction methods are employed to derive short run price and income elasticities estimated results are quite robust not only in terms of statistical prowess but also in terms of economic intuition and indicate that over the long run both price and income elasticities are close to unity while short run price and income elasticities are less in absolute value than their long run counterparts there seems to be some divergence in short run parameters from a subsample analysis overall results seem to imply that for china coal consumption should remain relatively constant as future modernization strategies for economic development are pursued in addition the study has clear methodological implications for estimating the long and short run elasticities in a demand function in general and in a wide variety of fields in future applied research

modeling monetary trends in italy using historical data the demand for broad money 1861 1990 in this paper we estimate a stable demand for money relationship for italy using a long series of historical data we extend previously available data sets to obtain a sample for the years 1861 to 1990 and use cointegration analysis and two stage estimation procedures to obtain a dynamic model for m2 demand by employing a small number of explanatory variables and a nonlinear error correction model we find a stable demand for money relationship our model incorporates significant inflation and interest rate effects in contrast to previous studies of this type

consumption saving and rational expectations some further evidence for the u k this paper examines implications of the rational expectations permanent income framework for quasi savings using u k data the residual from a cointegrating regression between income and consumption provides the quasi savings series that is used in conjunction with differenced income in a bivariate vector autoregression with associated restrictions and exclusion tests a further implication is that savings should granger cause labor income changes incomes and consumption are found to be cointegrated in levels as a robust result and the bivariate system performs well however savings granger cause labor income changes with a perverse positive sign and exclusion restrictions fail copyright 1989 by royal economic society

lithuania s food demand during economic transition the linear approximate version of the almost ideal demand system la aids model is estimated using data from the lithuanian household budget survey hbs covering the period from july 1992 to december 1994 price and real expenditure elasticities for 12 food groups were estimated based on the estimated coefficients of the model very little or nothing is known about the demand parameters of lithuania and other former socialist countries so the results are of intrinsic interest estimated expenditure elasticities were positive and statistically significant for all food groups while all own price elasticities were negative and statistically significant except for that of eggs which was insignificant results suggest that lithuanian household consumption did respond to price and real income changes during their transition to a market oriented economy

monetary economic myth and econometric reality few of the main macro economic forecasting systems can produce sensible forecasts without the tender loving care of their proprietors many econometric equations in com mon use show significant deterioration in the accuracy with which they characterise data as time passes and many economists are sceptical about empirical evidence feeling it lacks credibility monetary relationships have the dubious distinction of being among the leaders in this field as witnessed by the very large mispredictions of m1 models in the usa over what is now known as the missing money period 1973 76 as well as during the recent great velocity decline 1979 82 in the uk models of m1 and m3 demand experienced large structural breaks following the competition and credit control regu lation changes and the move to floating exchange rates perhaps it is no surprise that goodhart s law should have been formulated with respect to money demand equations

unit root and cointegration tests timeseries versus panel estimates for international health expenditure models classical regression estimates of the determinants of the oecd health expenditures are useful for policy formulation and evaluation however if the underlying timeseries data are not collectively stationary in levels the estimated parameters are faulty and can misguide health policy until very recently the crucial stationarity tests were ignored in a large number of studies on international comparisons stationarity adf phillips perron ips heterogeneous panel and cointegration engle granger bivariate johansen s multivariate tests are conducted here using 1960 1997 health expenditures data 1998 cd rom of 19 oecd countries it is found that extending the time series data length affects the order of integration and number of cointegrating vectors however it is arguable whether the order of integration decreases or increases as more observations are added for testing the failure of the johansen and engle granger cointegration tests for most of the oecd countries cautions policy makers against

the demand for tourism in north east england with special reference to northumbria an empirical analysis abstract this paper examines the trends of tourism in north east england in particular we focus on the area of northumbria to show the potential of tourism for economic development in the region within this analysis we concentrate on the demand for tourism in the region and in particular we are concerned with tourism by uk residents in northumbria domestic tourism the long run relationship between domestic tourism demand and a number of economic factors effecting this demand is considered using the johansen and juselius 1990 1992 multivariate cointegration analysis an error correction model is then proposed for short run forecasting of domestic demand for tourism in northumbria

deterministic and stochastic trends in the time series models a guide for the applied economist applied economists working with time series data face a dilemma in selecting between models with deterministic and stochastic trends while models with deterministic trends are widely used models with stochastic trends are not so well known in an influential paper harvey 1997 strongly advocates a structural time series approach with stochastic trends in place of the widely used autoregressive models based on unit root tests and cointegration techniques therefore it is important to understand their relative merits this article suggests that both methodologies are useful and they may perform differently in different models this article provides a few guidelines to the applied economists to understand these alternative methods

an investigation of the long run properties of aggregate non durable consumers expenditure in the united this paper estimates the effects of the modeling of nondurable consumption in the light of the five years of new data since the publication of the paper by j e h davidson et al 1978 and the development of the new cointegration technique of r f engle and c w j granger 1987 existing models are found to be inadequate on two grounds they fail parameter stability tests and they do not contain a suitable equilibrium specification the paper uses the cointegration approach to search for an encompassing model that is both stable and cointegrates the main finding is that the analysis must be extended to allow for differential income effects caused by changing higher rate income tax bands copyright 1989 by royal economic society

the long run stability of the demand for money italy 1861 1996 this paper examines the stability of the demand for money in italy using a newly extended data set for the period 1861 1996 we examine how the evolution of the financial system in italy and policy shifts have affected the behavior of the long run demand for money and present tests of structural stability we find the demand for broad money to be remarkably stable despite periods of considerable economic turbulence in addition we present evidence on the monetary transmission mechanism our results shed light on attempts to model long run relationships in other countries such as the uk and the us

elasticities in aids models comment green and alston have written two articles 1990 1991 for the journal on the correct method of calculating elasticities for the linear approximate almost ideal demand system la aids their articles are a departure from the typical approach to the la aids the la aids is generally used to estimate the parameters of deaton and muellbauer s almost ideal demand system aids the elasticity formulae for the aids are known green and alston s formulae are relevant only if the la aids is treated as a system in its own right such a treatment has merit however after checking the implications of treating the la aids as a system in its own right we discover that the la aids itself lacks merit

a stochastic volatility model with conditional skewness we develop a discrete time affine stochastic volatility model with time varying conditional skewness svs importantly we disentangle the dynamics of conditional volatility and conditional skewness in a coherent way our approach allows current asset returns to be asymmetric conditional on current factors and past information which we term contemporaneous asymmetry conditional skewness is an explicit combination of the conditional leverage effect and contemporaneous asymmetry we derive analytical formulas for various return moments that are used for generalized method of moments gmm estimation applying our approach to s p500 index daily returns and option data we show that one and two factor svs models provide a better fit for both the historical and the risk neutral distribution of returns compared to existing affine generalized autoregressive conditional heteroscedasticity garch and stochastic volatility with jumps svj models our results are not due to an overparameterization of the mod

estimating food demand in paraguay from household survey data we estimate a food demand system in paraguay based on the 1997 national household survey considering 12 food categories to obtain demand elasticity estimates from household survey data accounting for quality effects measurement errors and censored observations price indexes are obtained from ordinary least squares predictions of changes in unitary values caused by spatial and temporal variations and the two step estimation procedure shonkwiler and yen 1999 is applied our approach yields reasonable estimates of combined quantity and quality responses with respect to price results suggest distinct consumption behavior in urban and rural areas particularly for chicken eggs dairy and fats and oils which are likely because of differences in the food distribution system and availability of nonmarket food sources

economic development and food production consumption balance a growing global challenge abstract rising affluence in major developing countries principally china and india and increasing diversion of agricultural resources for energy production usa and brazil sharply increase agricultural resource demand food consumption and production changes during development are analyzed using resource based cereal equivalent measures diet upgrades to livestock products require fivefold increases in per capita food resource use reflecting a consistent pattern which is only marginally affected by land base food consumption increases exceed production during early development leading to imports consumption eventually stabilizes at high incomes but production falls short in land scarce countries pork and poultry consumption increase the most less efficient beef and dairy production command a majority of agricultural resources

elasticities in aids models in the literature a variety of approaches have been used to calculate demand elasticities in almost ideal demand system aids models of demand it is common to estimate the linear approximate almost ideal demand system la aids instead of the aids when the la aids is estimated all of the previously reported approaches to compute elasticities are theoretically incorrect this paper presents correct formulas for la aids elasticities and illustrates the potential errors from using incorrect computing the almost ideal demand system aids of deaton and muellbauer 1980a b has become popular in recent years anderson and blundell blanciforti and green 1983a b blanciforti green and king chalfant eales and unnevehr fujii khaled and mak fulponi heien and willett murray parsons ray a variety of approaches to computing elasticities has been used and some of the approaches may lead to significant errors this paper clarifies the differences between alternative approaches to estimating demand elasticities in aids models

impacts of world prices transmission to domestic rice markets in rural iran abstract this paper attempts to assess the degree to which iranian rural households have responded to the change in price of imported rice due to exchange rate unification and to examine the extent to which the policy has affected the economic welfare of various household income groups particularly the poor utilizing samples of 2472 households selected from national expenditure survey data of 2002 and 2003 armington and pass through elasticities were calculated as two measures of substitutability and are discussed separately for each household group in these areas the findings of this study indicate that domestic rice prices are associated differently with imported rice prices among the households however a price increase in imported rice that is mainly consumed by the poor worsens their position much more severely than for the rich people who mainly prefer domestic rice the findings contribute to the understanding of how price changes resulting from trade liberalization may affect various groups of households and the ways they respond to such changes in prices

cointegration and dynamic time series models abstract this paper provides a survey of some of the recent developments in the field of econometric modelling with cointegrated time series in particular we describe the testing and estimation procedures which have become increasingly popular in the recent applied literature in addition to the two stage procedure proposed by engle and granger we consider extensions to the modelling of dynamic models with cointegrated variables such as the estimation of models with multiple cointegration vectors simultaneous systems models with seasonally integrated and cointegrated variables furthermore we illustrate the practical application of the techniques describes in the paper by means of a tutorial data set

cointegration and stock prices the random walk on wall street revisited abstract one of the more famous and empirically regular instances of unit roots occurs in stock price series where they are consistent with rational expectations and efficient markets under certain assumptions in this paper we investigate the dynamic behavior of five stock prices over the volatile period from january 1972 through december 1979 finding that the series are cointegrated with one dominant common trend a component with an estimated root of 0 95 in addition we find a lesser trend and two complex roots in the cycle model these findings are validated by out of sample forecasts beginning in january 1980 in addition to mean squared error criteria the forecasts are evaluated nonparametrically in two separate applications of a test due to henriksson and merton

evaluating the linearized almost ideal demand system linearizing the almost ideal demand system laids by recourse to the stone share weighted price index is common practice two issues are addressed here first scrutiny of the errors in variables implications of the linearization reveals that not only is the sur estimator inconsistent but a consistent iv estimator cannot be constructed second some alternatives to the green alston elasticities specifically designed for the laids model are developed but neither these nor the green alston elasticities are found to have any advantages over the conventional elasticity formulae some errors in the green alston 1990 paper are corrected the inconsistency and elasticity issues are documented by a monte carlo investigation
