the turning black tide energy prices and the canadian dollar the authors revisit the relationship between energy prices and the canadian dollar in the amano and van norden 1995 equation which shows a negative relationship such that higher real energy prices lead to a depreciation of the canadian dollar

interest rate arbitrage in currency baskets forecasting weights and measuring risk we use a time series modeling approach to address two related questions of interest to foreign exchange market participants and policy makers dealing with basket currencies first how are unknown weights appropriately extracted from basket currencies second how does one correctly account for the risk in terms of conditional variance of expected profits that time varying weights add to the standard basket hedge position we suggest a methodology that can provide answers to these questions and apply it to the heavily traded thai baht currency basket

the long run relationship between productivity and capital abstract using panel cointegration techniques we show a cointegrating relationship exists between capital and productivity in 446 manufacturing industries panel dols and fmols estimates reveal that innovations to productivity increase and granger cause capital movements

structural transformation the mismeasurement of productivity growth and the cost disease of services if workers self select into industries based upon their relative productivity in different tasks and comparative advantage is aligned with absolute advantage then the average efficacy of a sector s workforce will be negatively correlated with its employment share this might explain the difference in the reported productivity growth of contracting goods and expanding services instrumenting with defense expenditures i find the elasticity of worker efficacy with respect to employment shares is substantially negative albeit estimated imprecisely the estimates suggest that the view that goods and services have similar productivity growth rates is a plausible alternative characterization of growth in developed economies jel e23 e24 h56 j24 o41 o47 one of the strongest and seemingly most accurate characterizations of the process and problems of growth in advanced economies is william baumol s cost disease of services baumol s argument begun in papers as early as 1965 and continuing to this very day e g baumol and bowen 1965 baumol 1967 baumol blackman and wolff 1985 and baumol 2012 starts from the premise that productivity growth is inherently more difficult to achieve in the production of services than in the pro

global imbalances and the intertemporal external budget constraint a multicointegration approach abstract this paper analyzes the external solvency of a group of 23 oecd countries for the period 1970 2012 the empirical strategy adopted underlines the increasing importance of the financial channel for the external adjustment as proposed in gourinchas and rey 2007 we unify the traditional approaches to testing for external sustainability considering the stock flow system created by the variables representing the external relationships of an open economy external sustainability is tested using several types of cointegration and multicointegration tests the results obtained point to weak sustainability in the flows analysis whereas some degree of strong sustainability is found for up to six countries in the stock flow approach among these countries we find both non european economies such as japan and new zealand and euro area members especially those with more restricted access to financing in the international markets

modelling long run comovements in equity markets a flexible approach abstract international equity markets linkages are characterized by nonlinear dependence and asymmetries we investigate shifts in long run comovements in stock markets by means of an interrupted markov switching cointegration specification this flexible approach allow us to study to what extent documented changes in global integration are permanent or whether market linkages are subject to changes using an illustrative sample from 1980 to 2012 for usa uk and hong kong stock price indices we find evidence of interrupted cointegration across these markets between may 1997 and april 2002 which is consistent with the decoupling of stock prices from fundamentals during the dot com bubble

the determinants of australian trade union membership summary this paper investigates the determinants of trade union membership in australia using the engle and granger 1987 theory of co integrated economic variables applying the theory of co integration yields a model of union membership which can be interpreted as distinguishing between long run and business cycle determinants of union membership the principal long run determinant of union membership is found to be the level of employment disaggregated by industry classification business cycle variables the real wage and the change in unemployment are also shown to influence movements in union density these findings are consistent with recent studies which have attributed the decline in union membership in australia since the early 1980s to the changing composition of employment and movements in the rate of unemployment

labour im mobility and monopsonistic exploitation of workers in the urban informal sector lessons from a field study it is well recognised in labour economics that employers in monopsonistic competition have market power to set wages below the productivity of workers if workers are immobile which causes monopsonistic exploitation of workers monopsonistic exploitation is propelled by employers expectations about the degree of im mobility of workers and therefore by ex post mobility of workers it hence begs a question of what determines the relative im mobility of informal workers which has significant implications for monopsonistic exploitation and working poverty in the urban informal sector from our field study of urban and peri urban labour markets in bangladesh by modifying the method of stochastic frontier analysis we explain the behavioural foundation to the relative im mobility of informal workers we thereby unravel the effects of individual and household characteristics sociological institutional factors and household ties including worker s kinship on the relative immobility of a worker that can in turn explain monopsonistic exploitation and working poverty widely prevalent in the urban informal sector of south asia

modelling money demand in germany in this paper an empirically stable money demand model for m3 in germany is presented the sample period 1975 94 includes german unification it is shown that this development has not substantially destabilized money demand parameter stability is extensively tested and not rejected applying encompassing tests this model encompasses two recent models but is not encompassed by them exogeneity of the explanatory variables is discussed and tested along the definitions given in engle hendry and richard 1983 there is evidence that inflation and long term interest rates are super exogenous with respect to the parameters of the demand for m3 model this result and the empirical long run money demand function presented in this paper may affect the applicability of the so called p star concept for german m3 1998 john wiley sons ltd

nonstationarity cointegration and structural breaks in the australian term structure of interest rates this article examines the unit root property of the australian short and long term interest rates using unit root tests that accommodate a single or two breaks under the null and or alternative hypothesis two breaks in interest rates are found to coincide with the 1982 83 and 1990 91 recessions or the 1993 inflation targeting period we further investigate the implications of these structural breaks on the cointegrating relationship implied by the single linear expectations hypothesis of the term structure of interest rates while there is evidence that the data are consistent with the expectations hypothesis at the shorter end of the term structure breaks in interest rates generate a shift in the cointegrating relationship thus altering the information content of the term structure failing to account for a regime shift in the cointegration regression the data erroneously supports the expectations hypothesis at the longer end of the term structure these results have profound implications for polic

tests for parameter instability in regressions with i 1 processes this article derives the large sample distributions of lagrange multiplier lm tests for parameter instability against several alternatives of interest in the context of cointegrated regression models the fully modified estimator of phillips and hansen is extended to cover general models with stochastic and deterministic trends the test statistics considered include the supf test of quandt as well as the lm tests of nyblom and of nabeya and tanaka it is found that the asymptotic distributions depend on the nature of the regressor processes that is if the regressors are stochastic or deterministic trends the distributions are noticeably different from the distributions when the data are weakly dependent it is also found that the lack of cointegration is a special case of the alternative hypothesis considered an unstable intercept so the tests proposed here may also be viewed as a test of the null of cointegration against the alternative of no cointegration the tests are applied to three data se

long run estimates of money demand new evidence from east asian countries and the presence of structural breaks conventionally the money demand function is estimated using a linear regression of the logarithm of money demand on a number of variables in this article we aim to estimate the long run properties of money demand specification for a number of east asian economies and within a panel framework with the presence of structural breaks various country specific coefficients are allowed to capture inter country heterogeneities consistent with theoretical postulates it is found that a the demand for money in the long run positively responds to real income and inversely to the interest rate spread inflation the real effective exchange rate and the us real interest rate b the long run income elasticity is greater than unity and c both the currency substitution and capital mobility hypotheses hold the empirical findings in this article can provide useful policy guidelines to the east asian countries central banks in their quest for price stability if one of the primary objectives of these countries

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

shifts in us savings long run asset accumulation versus consumption smoothing recently savings rates have fluctuated considerably in the usa the implications of these movements have interested both policy makers and economists this paper considers two reasons why savings may change i a change in the economy s desired long run capital stock and ii the economy s desire to smooth its consumption through time to identify both kinds of movements in us savings the permanent income hypothesis pih is modified to incorporate discrete breaks evidence suggests that discrete breaks in saving occurred during 1972 74 and again during the mid 1980s and when breaks are accounted for it is found that rises falls in saving anticipate falls rises in output suggesting that people use savings to help smooth consumption over time consistent with the pih

testing the monetary model of exchange rate determination new evidence from a century of data abstract we test the long run monetary model of exchange rate determination for a collection of 14 industrialized countries using data spanning the late nineteenth or early twentieth century to the late twentieth century interestingly we find support for a simple form of the long run monetary model in over half of the countries we consider for these countries we estimate vector error correction models to investigate the adjustment process to the long run monetary equilibrium in the spirit of meese and rogoff journal of international economics 14 1983 3 24 we also compare nominal exchange rate forecasts based on monetary fundamentals to those based on a naive random walk model

the impact of economic growth on co2 emissions in azerbaijan abstract this paper investigates the relationship between the economic growth and co2 emissions in azerbaijan a cointegration analysis is conducted over the period 1992 2013 for getting more robust results johansen ardlbt dols fmols and ccr methods are employed to explore cointegration and estimate long run coefficients we use cubic quadratic and linear specifications and conclude that the last one is an adequate representation for the impact of the economic growth on co2 emissions in azerbaijan the results from the different cointegration methods are consistent with each other and show that the economic growth has a positive and statistically significant impact on the emissions in the long run implying that the ekc hypothesis does not hold for azerbaijan the income elasticity of co2 emissions using different methods is found to be between 0 7 and 0 8 moreover we find that any short run imbalance can be adjusted towards the long run equilibrium path within less than one year the paper concludes that measures to increase energy efficiency carbon pricing instruments in production and international domestic trade activities and nationwide social awareness programs to instruct about the negative consequences of pollution can be considered as relevant environmental policies aimed at reducing carbon emissions

electricity consumption employment and real income in australia evidence from multivariate granger causality tests this paper examines the relationship between electricity consumption employment and real income in australia within a cointegration and causality framework we find that electricity consumption employment and real income are cointegrated and that in the long run employment and real income granger cause electricity consumption while in the short run there is weak unidirectional granger causality running from income to electricity consumption and from income to employment

the role of natural gas consumption and trade in tunisia s output this paper examines the impact of natural gas consumption real gross fixed capital formation and trade on the real gdp in case of tunisia over the period of 1980 2010 we used auto regressive distributed lag ardl bounds testing approach to test the existence of long run relationship between the variables the vector error correction method vecm granger approach is applied to test the direction of causal relation between the series our findings indicate the existence of long run relationship among the variables natural gas consumption real gross fixed capital formation and trade add in economic growth natural gas consumption real gross fixed capital formation and real trade granger cause real gdp these findings open up new insights for policy makers to formulate a comprehensive energy policy to sustain economic growth for long run

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

uncovering the interrelationship between the u s stock and housing markets a bootstrap rolling window granger causality approach abstractthe purpose of this study is to investigate the time varying interrelationship between the housing market and the stock market in the u s during the period of 1890 2013 by employing a rolling window subsample with a bootstrap granger causality test the rolling window allows for structural changes in the economy over time whereas previous studies have not identified a causal relationship between the u s housing price index and the sp500 stock price index this new analysis is the first to identify certain periods wherein either the wealth effect or the investment effect can be observed

the evolution of price elasticity of electricity demand in south africa a kalman filter application abstract in south africa the electricity mismatch of supply and demand has been of major concern additional to past problems the 2008 electricity crisis made the solution crucial after its damaging consequences to the economy the disagreement on the need and consequences of the continuous electricity price hikes worsens the situation to contribute to the recent electricity debate this paper proposes a time varying price elasticity of demand for electricity the sensitivity of electricity consumption to price fluctuations changes throughout the years the main purpose of this study is the estimation of the price elasticity of electricity in south africa during the period 1980 2005 by employing an advanced econometric technique the kalman filter apart from the decreasing effect of electricity prices to consumption 71 8 in the 1990s and 94 5 in the 2000s in average our results conclude to an important finding the higher the prices for example in the 1980s the higher the sensitivity of consumers to price fluctuations thus further increases of the electricity prices may lead to changes in the behaviour of electricity consumers focusing their efforts on improving their efficiency levels by introducing demand side management techniques or even turning to other sources of cheaper energy

intertemporal substitution imports and the permanent income model abstract we examine the importance of intertemporal substitution in u s import consumption using a model of permanent income that allows for random preference shocks and additive separability the latter feature allows us to take two estimation approaches in the first approach we show that there is a cointegrating restriction imposed by the first order conditions of the model which allows us to estimate the intertemporal elasticity of imported and domestic goods consumption in the second approach we estimate the euler equations using generalized method of moments this approach however requires us to place some restrictive assumptions on the model that are not required for the first estimation approach thus the two different approaches allow an assessment of the severity of these restrictive assumptions which are often imposed in the literature

global economic activity and crude oil prices a cointegration analysis abstract this paper empirically investigates the cointegrating relationship between crude oil prices and global economic activity the kilian economic index is used as an indicator of global economic activity based on a supply demand framework and the cointegration theory we find that real futures prices of crude oil are cointegrated with the kilian economic index and a trade weighted us dollar index and crude oil prices are influenced significantly by fluctuations in the kilian economic index through both long run equilibrium conditions and short run impacts we also develop an empirically stable data coherent and single equation error correction model ecm which has sensible economic properties empirical results based on the ecm show that the adjustment implied by a permanent change in the kilian economic index is a relatively drawn out process

a long march perspective on tobacco use in canada in this paper we present a model of tobacco demand in canada with a view to establishing if price and tax policy on the one hand or educational regulatory and demographic influences on the other have been primarily responsible for the substantial drop in consumption since 1980 we address some methodological and econometric issues that have escaped the attention of some analysts to this point using data for the period 1972 2000 we find that non price developments have had a strong deterrent effect and that the price elasticity of demand is now lower than even the recently obtained low estimates propose these findings have strong public policy content jel classification i12 c13 c22 une perspective de longue haleine sur l usage du tabac au canada dans ce memoire on presente un modele de la demande de tabac au canada en vue d etablir laquelle des deux strategies d une part la politique de prix et d imposition de taxes et d autre part les influences de l education de la reglementation ainsi que les changements demographiques a ete davantage responsable de la chute importante dans la consommation du tabac depuis 1980 le texte examine certains problemes methodologiques et econometriques qui ont jusqu ici echappea l attention des analystes a l aide de donnees pour la periode 1972 2000 on montre que les facteurs qui n ont rien a voir avec le prix ont eu un fort effet dissuasif et que l elasticite de la demande par rapport au prix est maintenant plus faible que les faibles elasticites suggerees par certaines etudes recentes ces resultats ont une grande importance pour la politique publique

the residential demand for electricity in australia an application of the bounds testing approach to cointegration this paper reports estimates of the long and short run elasticities of residential demand for electricity in australia using the bounds testing procedure to cointegration within an autoregressive distributive lag framework in the long run we find that income and own price are the most important determinants of residential electricity demand while temperature is significant some of the time and gas prices are insignificant our estimates of long run income elasticity and price elasticity of demand are consistent with previous studies although they are towards the lower end of existing estimates as expected the short run elasticities are much smaller than the long run elasticities and the coefficients on the error correction coefficients are small consistent with the fact that in the short run energy appliances are fixed

effects of exchange rate variations on bilateral trade with a vehicle currency evidence from china and singapore abstract using a testable gravity type bilateral trade model derived from an underlying demand and supply model this paper explores the effects of exchange rate variations on bilateral trade in an exchange rate regime with a vehicle currency the introduction of the vehicle currency allows us to figure out whether variations in the trade volume due to the fluctuation of the bilateral exchange rate are primarily due to changes in demand or in supply or both more specifically in this theoretical framework the appreciation of one country s currency against the vehicle currency is expected to promote its imports but the effect of revaluation of the country s currency against the vehicle currency on its exports is ambiguous moreover high volatility of the exchange rate of one country s currency against the vehicle currency is also expected to depress its import volume from the empirical point of view the decomposition of the bilateral exchange rate of two currencies into the bilateral rates of these two currencies against the vehicle currency provides a new alternative to avoid the econometric problem of potential reverse causality in assessing the effects through compiling a novel monthly bilateral trade dataset between china and singapore over 21 years or 252 months we empirically test the predictions of our model which get robust support from the results

cointegration in panel data with structural breaks and cross section dependence summary the power of standard panel cointegration statistics may be affected by misspecification errors if structural breaks in the parameters generating the process are not considered in addition the presence of cross section dependence among the panel units can distort the empirical size of the statistics we therefore design a testing procedure that allows for both structural breaks and cross section dependence when testing the null hypothesis of no cointegration the paper proposes test statistics that can be used when one or both features are present we illustrate our proposal by analysing the pass through of import prices on a sample of european countries copyright 2013 john wiley sons ltd

the effects of macroeconomic stability on foreign trade an analysis for spain 1986 2000 two main factors underlie the rebirth of interest in the study of the influence of the real exchange rate on trade the reduction of its volatility and the current trend towards price stability the objective of this study is to analyse the effects of the process of nominal convergence required of the european member states for the fulfilment of monetary integration on foreign trade flows the case of spain which is especially interesting in this context is studied for the period 1986 to 2000 the results of estimating the aggregate functions of the export and import of goods shows how macroeconomic stability has altered the behaviour of trade with respect to the two basic determinants income and prices how it has caused a significant structural change in the real exchange rate and finally how it has laid the explanatory bases for transactions in the twenty first century with the single currency the euro

foreign investors influence on the real estate market capitalization rate evidence from a small open economy abstractthis article adds to the scarce literature on the influence of international investment flows on local real estate values we hypothesize that a greater foreign investor presence in a real estate market results in a lower capitalization rate and examine whether this holds true in the helsinki cbd office market in finland this market provides an interesting case study by being part of a small open economy in which the presence of foreign investors has substantially varied over time the dynamic ols estimations using data for the period 1990 2015 provide support for the hypothesis the baseline results show a highly statistically significant negative impact of foreign investor participation on the capitalization rate the point estimates indicating that a 10 point growth in the share of foreign buyers of the total transaction volume decreases the cap rate by approximately 30 basis points

what explains the deviations of purchasing power parity across countries international evidence from macro data abstract this paper explores systematic cross national sources affecting the amplitude of purchasing power parity ppp deviations we theoretically show that a more open economy has smaller ppp deviations as its monetary factors are less dominant 63 cross country data evidences this prediction

exploring consumption based asset pricing model with stochastic trend forcing processes using canadian data the consumption based asset pricing model is studied defined in terms of nondurable and durable goods consumption a two stage estimation procedure is used which takes account of the presence of common stochastic trends in the forcing processes this method yields more reasonable estimates of the preference parameters than the previous studies did and the asset pricing equation is not rejected by the data moreover the preference specification adopted in this paper allows a number of useful economic information to be obtained the additive separability assumption and the cobb douglas functional form of the utility function are ruled complements in the sense of edgeworth and pareto

an application of cointegration theory in the estimation of the almost ideal demand system for food consumption in bulgaria abstract the almost ideal demand system is applied to consumption in bulgaria it is argued that the conventional estimation of the almost ideal model should be done within the framework of contemporary time series methodology in this paper the canonical cointegrating regression procedure of park is applied it is argued that the results of the almost ideal demand system that are presented are consistent with both theory and casual observation of consumer behaviour in bulgaria

adjustment costs and import demand behavior evidence from canada and the united states abstract in this paper we examine whether adjustment costs are a significant source of the observed sluggish adjustment of canadian and us import demand we use a simple model of a utility maximizing domestic consumer under the assumption of integrated forcing variables to examine the importance of adjustment costs this formulation of the problem allows us to exploit the recently developed theory of cointegration to estimate the structural parameters of the model using a two step methodology moreover the formulation incorporates an element of forward looking behaviour into the decision process a feature that is important if one assumes adjustment costs are a significant source of persistence in import demand adjustment the empirical results from a euler equation imply that adjustment costs in canada and the united states are important

terms of trade and real exchange rates the canadian evidence abstract this paper presents empirical evidence linking the canada us real exchange rate with the terms of trade using recently developed econometric methods for nondashstationary data we find that the real exchange rate is cointegrated with terms of trade variables and that causality runs from the terms of trade to the exchange rate we then construct a simple exchange rate equation that satisfies several specification tests and performs better than a random walk in post sample forecasting experiments the results suggest that much of the variation in the real exchange rate is attributable to movements in the terms of trade and that the influence of monetary factors is secondary

the effect of emergency liquidity assistance ela on bank lending during the euro area crisis abstract we examine the impact of emergency liquidity assistance ela on bank lending in eleven euro area countries during the financial crisis with the intensification of the crisis ela took on a pivotal role in some countries however assessments of the quantitative impact of ela in the literature are non existent we estimate a structural panel model for the determination of bank lending which includes the amount of ela received by each bank allowing us to investigate the direct effect of ela on lending our model corrects a mis specification found in the prototype model used in the literature we then undertake a var analysis which allows us to address the effect of ela on gdp finally we examine spillover effects among banks indicating that ela generated positive spillovers to other banks

regionalisation versus globalisation in european financial market integration evidence from co integration analyses abstract motivated by recent regulatory changes this study investigates the degree of integration in retail lending in six core european union eu countries using co integration methodology which allows to investigate the presence and effects of structural breaks while in the pre break period we could detect integration to a limited degree the evidence for integration weakened in the post 1992 period this could however reflect a convergence process particularly with respect to spreads this result is clearly a regional not a global phenomenon as european lending rates are not yet fully integrated the still segmented financial markets pose a challenge for a unified monetary policy

declining discount rates and the fisher effect inflated past discounted future uncertain and persistent real interest rates underpin one argument for using a declining term structure of social discount rates in the expected net present value enpv framework despite being controversial this approach has influenced both the inter agency working group on cost benefit analysis and the uk government s guidelines on discounting we first clarify the theoretical basis of the enpv approach then rather than following previous work which used a single series of u s treasury bond returns we treat nominal interest rates and inflation as co integrated series and estimate the empirical term structure of discount rates via the fisher effect this nests previous empirical models and is more flexible it also addresses an irregularity in previous work which used data on nominal interest rates until 1950 and real interest rates thereafter as we show the real and nominal data have very different time series properties this paper therefore provides a robustness check on previous discounting advice and updated methodological guidance at a time when governments around the world are reviewing their guidelines on social discounting the policy implications are discussed in the context of the social cost of carbon nuclear decommissioning and public health

commodity currencies and the real exchange rate abstract this paper examines whether the real exchange rates of commodity exporting countries and the real prices of their commodity exports move together over time using international monetary fund imf data on the world prices of 44 commodities and national commodity export shares we construct new monthly indices of national commodity export prices for 58 commodity exporting countries over 1980 2002 evidence of a long run relationship between national real exchange rate and real commodity prices is found for about one third of the commodity exporting countries the long run real exchange rate of these commodity currencies is not constant as would be implied by purchasing power parity based models but is time varying being dependent on movements in the real price of commodity exports

us deficit sustainability a new approach based on multiple endogenous breaks recent empirical work has questioned the consistency of us fiscal policy with an intertemporal budget constraint empirical results have tended to indicate that the deficit process has undergone at least one structural shift during recent decades with the deficit becoming either unsustainable or sustainable in only a weak sense in the post shift period in this paper we re examine sustainability using a new approach based on a cointegration model with multiple endogenous breaks a bayesian methodology is applied incorporating markov chain monte carlo simulators in contrast to previous analyses we find evidence of a sustainable deficit process over the 1947 1992 period despite the occurrence of breaks during the 1970s and 1980s copyright 2000 john wiley sons ltd

rights based management and alaska pollock processors supply using data from the alaska pollock fishery this study investigates the link between the implementation of rights based management and processors price responsiveness in a multiproduct fishery the analysis is based on cointegration with structural breaks to provide empirical evidence of a change in the long run relationship between processors production product prices and whole fish deliveries the results indicate that the endogenously determined structural breaks happened near the time when this fishery implemented individual fishing quotas furthermore the estimation of the cointegrating vector indicates that the processors of this fishery are significantly more price responsive after the change in management copyright 2008 oxford university press

german monetary unification and the stability of the german m3 money demand function abstract this paper employs quarterly data from the whole of germany to test the stability of m3 demand for money the methodology is based on an application of the cusum and cusumsq in the context of error correction modeling and cointegration the results reveal some instability in m3 money demand function

stability of money demand function revisited in china as china s economic reforms have undergone significant structural changes after 1979 it has been rather difficult to formulate a stable money demand function over the period following that year while previous literature on the long run relationship of money demand in china shows the existence of stable money demand this article revisits the stability of the china money demand function over the period after 1979 to employ the unit root tests and the cointegration tests with structural break the empirical evidence demonstrates that economic and financial deregulation did affect the stability of demand for money in china over the period 1977 to 2002 moreover the estimated long run income and interest elasticity are respectively 1 01 1 11 and 0 14 0 08 using the real m1 m2 equation in addition real income and the interest rate are found to be weakly exogenous we overall do find structural breakpoints mainly in 1980 and 1993 and they look to match clearly with corresponding critical financia

nonlinear equilibrium correction in u s real money balances 1869 1997 several theoretical models of money demand imply nonlinear functional forms for the aggregate demand for money characterized by smooth adjustment toward long run equilibrium in this paper we propose a nonlinear equilibrium correction model of u s money demand that is shown to be stable over the sample period from 1869 to 1997

instability in cointegration regressions a brief review with an application to money demand in portugal this study addresses some modelling questions related to the possibility of structural change in models with nonstationary variables focusing on cointegration issues some methodological aspects are discussed attempting to integrate coherently the several steps of the modelling strategy these range from unit root to cointegration testing and to testing for instability in the cointegration vector an empirical example with portuguese data tries to illustrate the usefulness of this approach where a simple money demand function is estimated using an error correction model ecm if a break is explicitly allowed in the cointegration vector the forecasting performance of the ecm improves

african terms of trade and the commodity terms of trade close cousins or distant relatives this paper examines whether there is a relationship between the commodity terms of trade the price of primary commodities relative to the price of manufactures and the net barter terms of trade of 42 sub saharan african countries for most countries there is little evidence of a stable long run relationship between the two terms of trade series accordingly the practice in the literature of proxying for movements in any given country s terms of trade by using an aggregate index of relative commodity prices is inappropriate and is likely to engender misleading policy conclusions

has federal budget deficit policy changed in recent years this paper applies new tests for parameter instability in cointegrated regression models to the u s federal government s intertemporal budget constraint in order to detect whether there has been a regime change in spending and taxing policies some researchers have argued that fiscal policy under presidents reagan and bush moved the u s deficit onto an unsustainable path my results suggest that government deficit policy in the 1980s was not significantly different from policies during the three earlier decades however a diverging debt gnp ratio suggests that the government will run into problems marketing its debt if current policy continues

the linkage between prices wages and labor productivity a panel study of manufacturing industries 1 introductionpolicy makers and financial analysts cite wage pressures and productivity gains as leading factors in explaining inflation this cost push explanation of inflation however is questioned by mehra 1991 1993 2000 who shows that prices explain wages but that wages are not a causal factor in determining inflation studies by hu and trehan 1995 and gordon 1988 1998 report evidence indicating that wage growth has no predictive content for inflation rejecting the cost push view emery and chang 1996 and hess 1999 demonstrate that these findings are sensitive to the sample period examined ghali 1999 using granger causality tests finds that wage growth does help to predict inflation supporting the cost push view a related but also relatively unexplored relationship is that between real wages and productivity although this link is the building block of many macroeconomic models and is frequently cited in intermediate macroeconomic textbooks few empirical works have tested this relationship 1recently a large number of studies have begun testing long standing macroeconomic hypotheses using panel unit root and or panel cointegration tests however few studies have employed industry level panel data sets the current article contributes to filling this void it employs manufacturing industry data to evaluate the long run dynamics between wages prices and productivity rather than the traditional approach of examining macroeconomic aggregates more specifically using annual four digit industry level data from the manufacturing sector over the period 1958 1996 this article examines the relationship between prices and wage adjusted productivity as well as the linkage between productivity and real wages using panel unit root and cointegration estimation methods the increased power and precision of the panel methods are particularly valuable in this context because they allow the researcher to more accurately test for the existence of a one for one cointegrating equilibrium between labor market variables and industry output prices an additional objective of this article is to show the advantages and disadvantages of employing panel unit root and cointegration tests we demonstrate that the considerable heterogeneity of the data imply that the practitioner must be cautious in making inferences about the linkage between variables when using either pooling estimation methods or aggregate level data our methodology accommodates for heterogeneity by averaging coefficients as well as examines outlier effects through quartile analysis heterogeneity of the cointegrating vector and cross correlations are accommodated through analysis by industry of the extent of cointegration across the panel and monte carlo simulations that calculate correctly sized critical values our results suggest that a stable long run relationship exists between prices and wage adjusted productivity as well as between real wages and productivity for many but not all industries both relationships however have considerably varied estimates and in most cases differ from the one for one linkage found by mehra and others in aggregate level data furthermore granger causality tests support one way causation from prices to per unit labor costs ulc in both the short and the long run hence the industry level data reject the standard cost push explanation of wage pressures contributing to inflation supporting the aggregate level findings of mehra 1991 1993 2000 and others our findings suggest that prices may be driven more by demand side factors than supply side factors results further support bidirectional granger causality in the long run between real wages and labor productivity this implies that changes in real wages lead to productivity changes and is not inconsistent with the efficiency wage hypothesis at the same time productivity movements affect real wages which is consistent with efficient labor markets

does self fulfilment of the inflation expectation exist abstractthis study examines the causal relationship between the actual and expected inflation in the u s using the bootstrap granger full sample causality test and sub sample rolling window estimation test to illustrate the self fulfilment of inflation expectations the full sample result indicates that there is a bidirectional causality between the actual and expected inflation showing the possibility of self fulfilment of inflation expectations which illustrates that inflation is driven by inflation expectation however considering structural changes in two series we find that the short run causal nexus between the actual and expected inflation using full sample data are fraudulent by adopting a time varying rolling window approach to revisiting the dynamic causal relationships this article identifies that the actual inflation has both positive and negative impacts on the expected inflation in distinct sub periods nevertheless inflation expectation exerts only negative effects on the actual inf

is the budget deficit too large some further evidence i introduction since the early 1980s the u s federal government has run unprecedented peacetime deficits the size of these deficits became a major issue in recent u s presidential elections for example during the 1992 elections ross perot successfully used his simple charts and tables to convey the notion that the size of the deficit was too large economists look at the deficit issue from a different perspective instead of emphasizing the size of the deficit at any particular point in time they are more concerned with the intertemporal solvency condition the present value of debt in the long run this condition focuses on the long run paths of interest inclusive expenditures and revenues unless these two variables trend together over the long run the government will have an incentive to default on the debt losing the confidence of investors from the standpoint of the intertemporal solvency condition are recent deficits too large do they represent boundless growth of government debt as an empirical proposition boundless growth of the debt corresponds to non stationarity of the deficit or the first difference of the debt recent developments in time series econometrics have provided ways to examine the intertemporal solvency condition for example hamilton and flavin 1986 and trehan and walsh 1991 apply stationarity tests to the u s federal deficit similarly hakkio and rush 1991 test for cointegration between interest inclusive expenditures and revenues while bohn 1991 tests for the cointegration of debt non interest expenditures and revenues hakkio and rush s results suggest that the deficit is too large for intertemporal solvency and thus the government has an incentive to default on its debt they conclude that over the period 1950 through 1989 interest inclusive expenditures and revenues are cointegrated but not one to one this suggests that although the present discounted value of the debt tends to zero the undiscounted value of the debt will be unbounded moreover they find that interest inclusive expenditures are not cointegrated with revenues over the period 1964 to 1989 the government debt appears to drift upward without bound overall hakkio and rush s results suggest that the government will have an incentive to default on the debt at some point in the future 1 we look at the issue from a different point of view we believe that a discrete break in the fiscal process occurred in the early 1980s as a result of several policy changes such as the 1981 economic recovery and tax act during the first reagan administration this reagan era change is modeled as a one time upward shift in the constant component of the deficit as mccallum 1984 shows a constant interest inclusive deficit does not imply boundless growth of government debt and should not provide an incentive to inflate away the debt as did previous research we conduct tests for the cointegration of interest inclusive expenditures and revenues as well as stationarity tests on the deficit 2 however we allow a shift in the intercept term of the cointegration and stationarity tests to capture the break in the fiscal process our results show that when the break is included expenditures and revenues are cointegrated with a coefficient not statistically different from unity i e that the deficit is stationary this contradicts the conclusions of hakkio and rush of course the way we choose the break date may be crucial to our analysis our initial choice of break date is based on prior information this is the approach used by perron 1989 who tests the u s gnp with a break chosen using prior information christiano 1992 criticizes perron 1989 on the a priori choice of the break date he suggests that the break date should be chosen using a formal pre test procedure moreover any statistical inference that follows must take this pre test procedure into account

housing and the great depression this article considers the structural stability of the relationship between the real housing price and real gdp per capita for an annual sample that includes the great depression we test for structural change in parameter values using a sample of annual us data from 1890 to 1952 the article examines the long run and short run dynamic relationships between the real housing price and real gdp per capita to determine whether these relationships experienced structural change over the sample period we find that temporal granger causality exists between these two variables only for subsamples that include the great depression for the other subsample periods as well as for the entire sample period no relationship exists between these variables

empirical analysis of the exchange rate channel in japan abstract this paper analyzes the significance of the exchange rate channel one of the transmission mechanisms of monetary policy it is important to evaluate this channel for japan because yen depreciation has been proposed as a policy to move the economy out of a liquidity trap our results suggest that in the past monetary expansion resulted in yen depreciation in the long and short run however there is no evidence to support the view that yen depreciation facilitated economic growth therefore we conclude that use of the exchange rate as a mechanism to boost the real economy was in our sample period at least premature

testing for the cointegrating rank of a var process with structural shifts tests for the cointegrating rank of a vector autoregressive process are considered that allow for possible exogenous shifts in the mean of the data generation process the break points are assumed to be known a priori it is proposed to estimate and remove the deterministic terms such as mean linear trend term and a shift in a first step then systems cointegration tests are applied to the adjusted series the resulting tests are shown to have known limiting null distributions that are free of nuisance parameters and do not depend on the break point the tests are applied for analyzing the number of cointegrating relations in two german money demand systems

are benefits from oil stocks diversification gone new evidence from a dynamic copula and high frequency data abstract oil is perceived as a good diversification tool for stock markets to fully understand this potential we propose a new empirical methodology that combines generalized autoregressive score copula functions with high frequency data and allows us to capture and forecast the conditional time varying joint distribution of the oil stocks pair accurately our realized garch with time varying copula yields statistically better forecasts of the dependence and quantiles of the distribution relative to competing models employing a recently proposed conditional diversification benefits measure that considers higher order moments and nonlinear dependence from tail events we document decreasing benefits from diversification over the past ten years the diversification benefits implied by our empirical model are moreover strongly varied over time these findings have important implications for asset allocation as the benefits of including oil in stock portfolios may not be as large as perceived

empirical testing of genuine savings as an indicator of weak sustainability a three country analysis of long run trends genuine savings has emerged as a widely used indicator of sustainable development this approach to conceptualising what sustainability is about has strong links to work published by anil markandya and colleagues over 20 years ago in this paper we use long term data stretching back to 1870 to undertake empirical tests of the relationship between genuine savings gs and future well being for three countries britain the usa and germany our tests are based on an underlying theoretical relationship between gs and changes in the present value of future consumption based on both single country and panel results we find evidence supporting the existence of a cointegrating long run equilibrium relationship between gs and future well being and fail to reject the basic theoretical result on the relationship between these two macroeconomic variables this provides some support for the gs measure of weak sustainability

self exciting effects of house prices on unit prices in australian capital cities this paper examines the long and short run relationship between australian house and unit prices across all capital cities over the period december 1995 to june 2015 we find that house and unit prices are cointegrated and based on the results of granger causality and generalised impulse responses that house prices significantly influence unit prices across all cities however bi directional causality responses exists only for major capital cities with the exception of brisbane we also for the first time apply self excited threshold models to explore the complex interplay between house and unit prices in australia we find that when the market for units is self excited or bullish the positive effects of house prices on unit prices are noticeably larger than otherwise there is a varying degree of herd mentality in the australian property market with sydney and darwin being the most and least excitable capital cities respectively

money demand in euroland abstract this paper explores the determinants of alternative monetary aggregates in euroland a sample consisting of quarterly data covering the 1980 1 1998 4 period is considered we are interested whether a conventionally defined money demand equation is stable in some aggregates as opposed to others both long run and short run relationships are considered in this paper overall the results indicate that broad narrow money demand in euroland is a stable unstable function of euroland wide income and interest rates

emerging floaters pass throughs and some new commodity currencies in spite of early skepticism on the merits of floating exchange rate regimes in emerging markets 8 of the 25 largest countries in this group have now had a floating exchange rate regime for more than a decade using parsimonious var specifications covering the period of floating exchange rates this study computes the dynamics of exchange rate pass throughs to consumer price indices we find that pass throughs have typically been moderate even though emerging floaters have seen considerable nominal and real exchange rate volatilities previous studies that set out to estimate exchange rate pass throughs ignored changes in policy regimes making them vulnerable to the lucas critique we find that within the group of emerging floaters estimated pass throughs are higher for countries with greater nominal exchange rate volatilities and that trade more homogeneous goods these findings are consistent with the pass through model of floden and wilander 2006 and earlier findings by campa and goldberg 2005 respectively furthermore we find that the indonesian rupiah the thai baht and possibly the mexican peso are commodity currencies in the sense that their real exchange rates are cointegrated with international commodity prices

tax and spend or spend and tax empirical evidence from greece spain portugal and ireland the paper examines empirically the relationship between government revenues and expenditures in four european countries greece spain ireland and portugal in relative terms all four may be considered as the poorest members of the european union yet they present a fairly diverse picture as far as their macroeconomic performance and fiscal position is concerned the empirical findings from cointegration and causality tests that are reported here indicate that in the case of greece and ireland tax and spending decisions are taken simultaneously by the fiscal authority the tax and spend hypothesis is supported in the case of spain while absence of any causal ordering between government expenditure and tax revenues has been established for portugal

estimating long run economic equilibria with stochastic trends an asymptotic theory is provided to analyze a menu of currently existing estimators of cointegrated systems we study in detail the single equation ecm seecm approach of hendry our theoretical results lead to prescriptions for empirical work such as specifying seecm s nonlinearly and including lagged equilibrium relationships rather than lagged differences of the dependent variable as covariates simulations support these prescriptions and point to problems of overfitting not encountered in the semiparametric approach of phillips and hansen 1990

intertemporal substitution in import demand and habit formation to study non durable import demand we extend previous work done by clarida 1994 and ceglowski 1991 by considering a two good version of the lifecycle model in which we introduce time non separability in the households preferences the model is estimated using quarterly data for the usa and france using the information contained in the observed stochastic and deterministic trends we derive a cointegration restriction used to estimate curvature parameters of the instantaneous utility function the remaining parameters are estimated in a second step by gmm the constancy of the different parameters is investigated in both the long and the short run habit formation turns out to be an important factor of import demand c 1998 john wiley sons ltd

cross country effects of regulatory capital arbitrage abstract one reason for the recent asset price bubbles in many developed countries could be regulatory capital arbitrage regulatory and legal changes can help traditional banks to move their assets off their balance sheets into the lightly regulated shadows and thus enable regulatory arbitrage through the securitized sector this paper adopts a global vector autoregression gvar methodology to assess the effects of regulatory capital arbitrage on equity prices house prices and economic activity across 11 oecd countries regions a counterfactual experiment disentangles the effects of regulatory arbitrage following a change in the net capital rule for investment banks in april 2004 and the adoption of the basel ii accord in june 2004 the results provide evidence for the existence of an international finance multiplier with about half of the countries overshooting u s impulse responses the counterfactual shows that regulatory arbitrage via the u s securitized sector may enhance the cross country reallocation of capital from housing markets towards equity markets
