is there private information in the fx market the tokyo experiment it is a common view that private information in the foreign exchange market does not exist we provide evidence against this view the evidence comes from the introduction of trading in tokyo over the lunch hour lunch re turn variance doubles with the introduction of trading which cannot be due to public information since the flow of public information did not change with the trading rules having eliminated public information as the cause we exploit the volatility pattern over the whole day to discriminate between the two alternatives private information and pricing errors three key re sults support the predictions of private information models first the vola tility u shape flattens greater revelation over lunch leaves a smaller share for the morning and afternoon second the u shape tilts upward an impli cation of information whose private value is transitory finally the morning exhibits a clear u shape when tokyo closes over lunch and it disappears when trading is introduced

legislative organization of fiscal policy in the voluminous literature on fiscal policy there is little evidence about the impact of legislative organization on shaping fiscal decisions by comparing different organizations of committee structure to control tax and spending policies this article presents such evidence regarding spending we test whether the dispersion of spending authority among multiple committees creates a problem similar to that of the common pool using american state data we find that when only one committee has the authority to spend spending is restrained relative to when spending authority is balkanized regarding taxation we hypothesize that if a single committee controls not only all spending authority but also all taxation authority that committee will have more incentive to tax than a committee that does not control spending it can obtain the benefits of increased taxation more directly again this proposition is supported by evidence at the state level

an analysis of the relationship between various redistributive programs and poverty this paper utilizes multivariate exogeneity causality tests to analyze the relationship between various income policy programs and the poverty rate the framework we develop allows us to make a distinction between intended poverty reduction objectives and automatic stabilizing behavior since we find that the poverty in a given year affects the funding of social programs in later years we conclude that these programs are primarily acting as automatic stabilizers i e the poverty reduction instruments do not appear to have been implemented with a relentless intent to reduce poverty a result consistent with tullock s 1983 1986 theorem

on the casual relationship between government expenditures and national income a research strategy is suggested that separates the issue of inference from the problems of prediction or of quantitative policy analysis of an empirical parametric model and illustrates a new methodology that enables this in a test for prima facie causality unlike the conventional parametric test the more powerful multiple rank f test is invariant to monotonic transformations of the variables and independent of the error distribution employing this test the wagnerian hypothesis supported by conventional parametric analysis is rejected and the conventional keynesian theory is accepted copyright 1990 by mit press

private information trading volume and stock return variances new evidence is provided on the determinants of stock return variances first when the tokyo stock exchange is open on saturday the weekend variance increases weekly variance is unaffected however despite an increase in weekly volume second the listing of u s stocks in tokyo substantially increases the number of trading hours but tokyo volume is negligible for these u s stocks and their 24 hour variance is unaffected the overall results are consistent with the predictions of private information based rational trading models but inconsistent with both the irrational trading noise and public information hypotheses

government spending and taxation what causes what in the past few years as federal deficits have risen to high nominal levels economists have argued about the effect that raising taxes ostensibly to reduce deficits might have on government spending some economists including milton friedman have argued that raising taxes will simply lead to more spending others including james buchanan and richard wagner have said that the high deficits themselves have been responsible for the growth of federal spending and that if that spending had to be financed completely by direct taxes people would demand that the federal government spend less a third group led by robert barro says that increased taxes and borrowing are results of increased government spending in section ii we briefly review various hypotheses about the relationship between federal government spending and revenues section iii describes the testing procedure used to discriminate between these hypotheses the results of four tests are presented in section iv section v contains a summary and major conclusions to foreshadow what follows we find no evidence that higher real federal taxes today lead to either higher or lower federal spending tomorrow on the other hand we find strong evidence that higher spending now will lead to higher taxes later our results support a view of the world in which the political system somehow determines how much to spend and then looks for revenue sources to finance that level of spending including direct taxation borrowing and money creation we also find evidence that real federal revenues are positively affected by real gross national product gnp real federal spending also rises with real gnp but it appears to be independent of the rate of inflation

taxes and subsidies for pollution intensive industries as trade policy abstract this paper constructs a model of international oligopoly with negative externalities in production in which optimal environmental policy responses to foreign emission tax and subsidy programs can be calculated it is shown that by granting subsidies for abatement efforts or for a heavily taxed polluting input domestic net welfare is improved by capturing a greater share of the world market since the subsidy programs are supposed to improve the quality of the global environment they can be justified on environmental grounds in addition we show that a pigouvion emission tax restores efficiency in natural resource allocation whereas subsidy programs are in principle used as instruments in imperfectly competitive international markets

the valuation and market rationality of internet stock prices this paper provides an analysis of some existing as well as new evidence of the relation between market prices and fundamentals in the internet sector over the period january 1998 to february 2000 appealing to results across a broad class of outcomes we demonstrate a strong circumstantial case against market rationality in particular we investigate i the level of internet stock prices given their underlying fundamentals ii responses of stock prices to information based events and iii the volatility of internet prices we review several potential explanations of these phenomena including one based on heterogeneous beliefs across investors who are subject to short sales constraints we provide a discussion of the empirical evidence supporting this latter explanation copyright 2002 oxford university press

privatization and government size a budget constraint view of government shows that privatization need not alter spending when it is implemented without a rule forbidding re use of the funding backing newly privatized programs only when these funds are eliminated from the budget process e g tax rebates or permanent deficit reduction can these funds not back new programs or expand existing programs this is an important caveat since privatization proposals do not contain such rules with such rules privatization can increase allocational efficiency and lead to smaller government size

causality and comovement between taxes and expenditures historical evidence from argentina brazil and mexico abstract this paper presents empirical tests for stationarity of fiscal deficits for three latin america countries it also examines the causality patterns between government expenditures and government revenues long historical series covering most of the 20th century for argentina brazil and mexico are used the findings suggest that deficits were stationary in argentina and mexico but not in brazil

the theory of rational bubbles in stock prices free disposal of equity which directly rules out the existence of negative rational bubbles in stock pric es also imposes theoretical restrictions on the possible existence o f positive rational bubbles the analysis in this paper shows that a positive rational bubble can start only on the first date of trading of a stock thus the existence of a rational bubble at any date woul d imply that the stock has been overvalued relative to market fundame ntals since the first date of trading and that prior to the first da te of trading the issuer of the stock and potential stockholders who anticipated the initial pricing of the stock expected that the stock would be overvalued copyright 1988 by royal economic society

trade and food policy case studies from three pacific island countries abstract there is growing interest in the use of trade policy to create a healthier food supply eighty percent of chronic disease deaths occur in low and middle income countries and a responsive food policy is an absolute necessity in this paper we analysed three trade related food policy initiatives to reduce the supply of fatty meat in the pacific in order to help public health workers understand how to effect policy change in sectors beyond the health portfolio we found that policy uptake and implementation were easier with advocacy tailoring the policy to the political context the selection of policy tools that align with government priorities e g trade commitments ideally tools that are already used by trade policy makers in other contexts and a broad justification for the policy initiative barriers to policy success included a focus only on health concerns not taking into account policy issues of other sectors limited engagement from other sectors in proposing and developing these cross sectoral policies and lack of a clear enforcement mechanism

in search of a signaling effect the wealth effects of corporate name changes abstract we find that evidence of a positive stock price reaction to the announcement of a name change is very weak and is sensitive to sample selection we interpret the evidence as a caution against the popular opinion that corporate name changes have significant valuation effects we also find little evidence that corporate name changes correspond to changes in a firm s stock return covariability with its industry index or changes in the firm s earnings growth rate these results cast doubt on two purported motives for name changes that they convey information to the market about changes in the firm s line of business or that they signal management s private information about the firm s future performance corporate name changes may serve useful purposes but such purposes have small valuation effects or tend to be anticipated by investors

public expenditure and economic growth in the gulf cooperation council countries this article uses a dynamic model calibrated to the gulf cooperation council gcc countries data to examine the nature of the relationship between government expenditure and economic growth the article finds that national income is a predictive factor of the expanding role of government as postulated by wagner empirical investigations do not support the hypothesis of public expenditure causing national income as proposed by the keynesian theory

the behavior of risk and market prices of risk over the nasdaq bubble period we exploit the information in the options market to study the variations of return risk and market prices of different sources of risk during the rise and fall of the nasdaq market we specify a model that accommodates fluctuations in both risk levels and market prices of different sources of risk and we estimate the model using the time series returns and option prices on the nasdaq 100 tracking stock our analysis reveals three key variations during the period from march 1999 to march 2001 first return volatility increased together with the rising nasdaq index level even though the two tend to move in opposite directions second although the market price of diffusion return risk averages around 1 82 over the whole sample the estimates reached negative territory at the end of 1999 the estimates reverted back to highly positive values after the collapse of the nasdaq market third the market price of jump risk increased with the rising nasdaq valuation and this increase in market price coincided with an increased imbalance in open interest between put and call options

the two faces of janus institutions policy regimes and macroeconomic performance in greece greece the two faces of janus institutions policy regimes and macroeconomic performance the clear change in policy regime in greece around 1974 offers an opportunity to assess the extent to which economic performance depends on institutional underpinning for twenty years up to 1974 greece enjoyed rapid growth high investment and low inflation during the next twenty years growth and investment collapsed and inflation became high and persistent i describe the political background to such clear institutional change and the nature of the two economic regimes the first providing coordination and commitment mechanisms to sustain adequate returns for high investment the second failing to do so the same change in political climate after 1974 raised public sector deficits and debt fuelling a trade deficit and monetary expansion entry to the ec did not cause the economic slowdown in greece but transfers from the ec did mask the underlying problem delaying necessary adjustment recent attempts to reverse greece s fortunes are in the right direction but as yet inadequate george alogoskoufis

co integration and error correction models the temporal causality between government taxes and spending several interesting papers have recently considered whether government taxes granger cause government spending or vice versa the findings based on standard granger 6 causality tests are not consistent manage and marlow 10 conclude that when evidence of one way causality exists federal taxes granger cause federal spending while anderson wallace and warner 1 conclude that the evidence supports one way causality in the opposite direction ram 11 reexamining the issue concludes that taxes granger cause spending at the federal level but that spending granger causes taxes at the state and local level von furstenberg green and jeong 13 in another related article examine the tax and spend spend and tax causality issue using a more general vector autoregressive var model they introduce in addition to federal taxes and spending two economic variables the gnp gap and the inflation rate decompose federal spending into several categories and remove the effects of automatic stabilizers when appropriate they find little evidence that taxes granger cause spending and limited evidence that spending causes taxes a finding which corresponds most closely to that of anderson wallace and warner 1 our purpose is to reconsider the causality issue with the aid of co integration and errorcorrection modeling our analysis illustrates with a specific example how sources of causality can be neglected in standard granger causality tests moreover addressing the question of temporal causality between government taxes and spending provides insight as to how different policies might or might not help control the growth of government the results of our estimating various co integration and error correction models with quarterly data suggest bi directional causality between government taxes and spending both for the federal and state and local sectors this finding counters the conclusions of previous studies when annual data are used however our

shrewd crude or simply deluded comovement and the internet stock phenomenon we show that i return comovement among internet stocks during the late 1990s and early 2000 was not exceedingly high ii there was substantial consistency in the manner by which investors distinguished among internet stocks and iii high comovement is most common during periods of price erosion these results cast doubt on the view that the extraordinary appreciation of internet stocks was due to the crude classification of all such stocks as members of a hot category

expenditures and receipts in state and local government finances comment the aim of this note has been to show that marlow and manage s 1987 paper suffers from serious methodological problems due to the non stationary data series used and the arbitrary lag lengths employed use of appropriate stationarity tests and optimal lag lengths of the variables change some of the basic conclusions of their paper contrary to their suggestion the presence of a feedback between local tax receipts and expenditures imply that local governments should be concerned with the implication of their spending and revenue enhancing decisions on their budget decisions to increase current expenditures may lead to higher future taxes similarly efforts to impose higher taxes to reduce budget deficits at the local government level may be futile due to a subsequent increase in spending

dynamics of government revenues and expenditures in industrial economies the sources of growth in government revenues and expenditures in 22 oecd countries is addressed the question of whether the revenue constraint is binding on the growth of government expenditures or whether the displacement effect of expenditure growth is binding is considered controls for the effects of the output gap and inflation rate on government revenues and expenditures in each of the 22 countries are presented a major conclusion is that reductions in spending are essential to reducing budget deficits and controlling government size

property tax and inter municipal migration in canada a multivariate test of the tiebout hypothesis this paper tests the causal ordering between property taxes and inter municipal migration using both bivariate and multivariate methods empirical results based on annual data for post war canada 1940 84 support the tiebout tullock hypothesis which implies that differential local tax system and public services induce inter comunity migration inter alia local spending and taxation are not therefore fully capitalized in property values the bivariate tests based on the granger sims test and hsiao s procedure indicate an instantaneous bidirectional causality between property taxes and migration but the multivariate granger test supports only a unidirectional causality from property taxes to migration

wagner s law versus displacement effect abstractthe public sector has grown dramatically over the past few centuries in many developed countries in this article we use wavelet methods to distinguish between two leading explanations for this growth wagner s law and the displacement effect in doing so we use the long term data of 10 oecd countries for a maximum time span of 1800 2009 we find that the validity of wagner s law is likely to vary strongly over time for each country a roughly similar feature in most of the countries is that the law is less valid in the earliest stage of economic development as well as in the advanced stages with the validity tending to follow an inverted u shaped pattern with economic development further our results indicate that the long run growth of government size cannot be adequately explained by wagner s law on the other hand the displacement effect appears to account for the bulk of the growth in most of the countries

cross border externalities and trade liberalization the strategic control of pollution the authors examine international trade in a commodity whose production creates a negative externality for the importing country and they consider the nations strategic policy choices when they can restrict trade and when they are bound by a free trade agreement when pollution abatement technology is available the exporting country induces its adoption despite national indifference to the externality in order to reduce the tariff in a free trade agreement environmental policy is used to exploit monopoly power in trade an alternative policy instrument a process standard is introduced national competition in controlling emissions leads to very restrictive antipollution measures we examine international trade in a commodity whose production creates a negative externality for the importing country and we consider the nations strategic policy choices when they can restrict trade and when they are bound by a free trade agreement when pollution abatement technology is available the exporting country induces its adoption despite national indifference to the externality in order to reduce the tariff in a free trade agreement environmental policy is used to exploit monopoly power in trade an alternative policy instrument a process standard is introduced national competition in controlling emissions leads to very restrictive anti pollution measures

government revenue government expenditure and temporal causality evidence from china dissatisfied with little evidence provided on various hypotheses concerning the revenue expenditure relation in china this paper is an empirical endeavour to fill the gap through a battery of econometric tests for causality based on vector error correction and vector autoregression models a more comprehensive testing strategy for unit roots and cointegration has been suggested and a bidirectional causality pattern has been found in china s government finance the paper thus concludes that attempts simply to change revenue or expenditure or both without taking into account of the interdependence between the two may be counter productive and the effects on aggregate demand of government debt financing in the presence of inflation may not be as detrimental as some economists would expect

estimating a fiscal reaction function the case of debt sustainability in brazil this article reviews recent trends in fiscal performance in brazil estimates fiscal reaction functions for the consolidated public sector and different levels of government and tests for the sustainability of the public debt dynamics the empirical analysis based on monthly data for the period 1995 2004 suggests that all levels of government react strongly to changes in indebtedness by adjusting their primary budget surplus targets in addition the central government appears to follow a spend and tax policy changes in revenue are affected strongly by expenditure about two thirds of changes in primary spending are offset by higher revenue over the longer term institutions are also found to matter for fiscal sustainability the responsiveness of the sub national fiscal stance to indebtedness as well as that of central government revenue to changes in primary spending appears to have become stronger after 1998 when ceilings on indebtedness were introduced

the causal relation between federal expenditures and receipts federal expenditures have consistently exceeded federal revenues since 1970 in fact the federal government has seen a surplus in only five years since 1950 the symptoms of such fiscal imbalance are of course budget deficits while budget deficits are nothing new in u s history the recent and projected size of the deficit during peacetime nonrecessionary years has been the cause of much concern to academics the news media and politicians this preoccupation with federal deficits has produced a variety of policy proposals to deal with them

the determinants of off budget activity of state and local governments the primary finding of this paper is that the off budget activity of the public sector is significantly and positively related to on budget activity by state and local governments we suggest the following policy implications one there appears to be evidence that the composition of total government activity is related to the relative costs of the alternative avenues of providing governmental activity future research into determining the nature of the relative cost differences may be one useful means of understanding both the composition of government activity as well as its total size two our ability to measure the true size of public sector participation in the economy must go well beyond our attempt here while we have presented information on one of the important hidden elements of public sector participation we are still a long way from effectively incorporating similar data on legislation regulations and so forth into our empirical tests further research into these issues is clearly warranted

public expenditure and national income causality further evidence on the role of omitted variables whether changes in public expenditure growth help predict changes in national income growth and or vice versa remains an important issue of sustained interest in the empirical public finance literature in recent years attention has mainly been confined to two specific areas namely estimation of the impact of the public sector on output growth by means of regression analysis and causality testing unfortunately the outcome of both types of analysis has been inconclusive focussing on the impact studies we note that a number of empirical investigations have attempted to measure the effect of the size of the public sector on overall economic growth for instance ram 19 utilizing a two sector model found that growth of government size has a positive effect on economic growth landau 14 15 however presented opposite evidence indicating that the government sector expansion led to a decline in output growth for many dcs and ldcs since 1960 in a recent study barth keleher and russek 4 estimated variants of ram s models with data for 30 countries their empirical results largely support a negative relationship between the scale of government and aggregate economic activity furthermore using the hausman procedure they rejected the hypothesis that the independent variables namely real government spending or other measures of the scale of the government depending on the specification in the regression equations are exogenous this strongly suggests that the conclusions reached by

globalisation and obesity he externalities arising as a consequence of trade liberalisation have rarely been a topicof much public debate a possible exception would be the relationship between the inter national trade and resulting environmental degradation markusen 1975 conrad 1993 ludema and wooton 1994 even then the mechanisms that link the volume of internationaltrade and the rate of environmental degradation are seldom adequately explained part of theproblem is that the environmental problems that are faced are extremely varied both in char acter and severity and it is fruitless to attempt to provide a single remedy for all of them but environmental degradation is hardly the only externality caused by trade liberalisation ifone considers a broader process such as globalisation de ned as a process by which national regional economies societies and cultures have become integrated through a global networkof economic technological socio cultural political and biological factors croucher 2004 rather than the trade liberalisation only the possibility of its resulting externalities increasessigni cantly there is for example a growing literature addressing possible adverse impact ofglobalisation including trade liberalisation on cultural diversity within in particular non wes tern countries castells 1997 cowen 2002 segerstrom 2003 in addition the relevance ofthe topic is underscored by the unesco 2001 universal declaration on cultural diversity which emphasises the role of cultural goods as vectors of identity and is concerned aboutcurrent trade imbalances in related sectors furthermore one can easily imagine the adverseimpact of globalisation with its free ow of people goods and in turn the lifestyle on spread ing of infectious diseases such as aids altman 1999 attawell 2004 according to the world health organization who 2006 approximately 1 6 billionadults were overweight and at least 400 million were obese in 2005 all around the world more recent statistics show that just in the united states 33 3 percentage of the total popula tion is obese and about 60 percentage is overweight or obese wyatt et al 2006 who 2009 these numbers set the united states among top three countries in the world with thehighest obesity rate who 2009 shared with egypt and saudi arabia obesity has not onlyincreased in developed countries but more surprisingly in developing countries as well according to the food and agriculture organization of the united nations fao 2008 obesity increases rapidly in developing countries even in those where hunger still exists forinstance the number of overweight people increased from less than 10 to 15 percentage inchina during the last two decades in sub saharan countries where hunger rates are the high est obesity is increasing as well some developing countries such as brazil and colombia have 40 percentage of overweight or obesity rate a number comparable to those in developedcountries due to this rapid and continuous global increase of obesity the who describesobesity as a global epidemic

keynes versus wagner public expenditure and national income for three african countries the public expenditure income hypothesis has long been debated in economics following keynes public expenditure is seen as an exogenous factor to be used as a policy instrument to influence growth on the other hand wagner argues that expenditure is an endogenous factor or an outcome not a cause of growth in national income the purpose of this paper is to apply both the granger and holmes hutton statistical procedures to test the income expenditure hypothesis for three african countries ghana kenya and south africa we find that the hypothesis of public expenditure causing national income is not supported by the data for these african countries

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

friedman tax cuts vs buchanan deficit reduction as the best way of constraining government i introduction both milton friedman and james buchanan believe that the federal government spends more than can be justified on the basis of economic efficiency both also agree that the reason for excessive government spending is that the political process allows people to realize the benefits from government spending without fully paying the cost of that spending but friedman and buchanan are in apparent disagreement on the effectiveness of alternative approaches at constraining government by considering friedman and buchanan s apparent disagreement at the level of fiscal policy it is possible to better understand their agreement at the level of constitutional policy milton friedman has argued that a reduction in taxes and tax revenues with an increase in the budget deficit serves the useful function of restraining government spending for example friedman 1982 60 61 has written i want to cut tax rates but if the lafferites were correct in the extreme form that a particular cut in taxes increased revenue then my conclusion would be that we hadn t cut tax rates enough because what i want to cut is government revenue that s what feeds government spending what they the big spenders want is to increase taxes so they will have more money to spend and won t have to cut spending the triumph in my opinion of the tax cutting policy that president reagan has been following is that he has made the big spenders talk on his terms for the first time they have to face up seriously to cutting spending 1 in contrast james buchanan argues that reducing taxes and increasing debt financing lowers the perceived cost of government spending and consequently increases government spending for example buchanan and wagner 1977 138 139 state the replacement of current tax financing by government borrowing has the effect of reducing the perceived price of government goods and services with the result that taxpayers increase their demands for such goods and services preferred budget levels will be higher and these preferences will be sensed by politicians and translated into political outcomes in discussing the economic policy of the reagan administration william niskanen who was a member and acting chairman of the president s council of economic advisers during the reagan presidency takes note of the conflicting views of friedman and buchanan according to niskanen 1988 109 milton friedman promoted a view that tax rates should be reduced at every opportunity believing that the resulting increase in the deficit would increase pressure to reduce federal spending james buchanan expressed a directly contrary view that a tax increase would reduce spending by increasing the perceived price of government services to the current voters niskanen continues by expressing his leanings toward the buchanan view a leaning based on his own research niskanen 1978 he points out however that recent empirical work is inconclusive with some supporting friedman s position and some supporting buchanan s niskanen 1988 109 concludes his discussion of the difference of opinion between friedman and buchanan by observing that economists and politicians unfortunately do not yet share a clear understanding of these taxing spending and budget deficit relations a simple model of taxation spending and deficit determination provides a framework for examining systematically the conflict between friedman and buchanan it makes clear that the relationships among these variables cannot be determined by empirical investigation alone because both the friedman and buchanan positions emerge as special cases of a more general model it is not surprising that empirical studies can be found to support either position indeed we demonstrate that historic episodes exist which support the positions of both men ii the model political decisions like market decisions are made in response to benefits and costs

measuring the restrictiveness of trade policy this article provides an introduction to the trade restrictiveness index tri which equals the uniform tariff that is welfare equivalent to a given pattern of trade protection unlike standard measures of trade restrictiveness the tri has a solid theoretical basis can incorporate both tariffs and quantitative restrictions and can be adapted to construct the trade policy equivalent of domestic distortions the article compares a number of applications and describes procedures for operationalizing the tri on a personal computer the authors conclude that the tri has considerable potential in empirical work

intrinsic bubbles the case of stock prices several puzzling aspects of the behavior of united states stock prices may be explained by the presence of a specific type of rational bubble that depends exclusively on aggregate dividends the authors call bubbles of this type intrinsic bubbles because they derive all of their variability from exogenous economic fundamentals and none from extraneous factors intrinsic bubbles provide a more plausible empirical account of deviations from present value pricing than do the traditional examples of rational bubbles their explanatory potential comes partly from their ability to generate persistent deviations that appear to be relatively stable over long periods copyright 1991 by american economic association

causality between public expenditure and national income this paper deploys the granger method to determine the directions and patterns of causality between national income and total as well as various components of public expenditure empirical results based on the data for india 1950 81 suggest that while at the disaggregate level the causal process is rather diverse it is essentially feed back type at the aggregate level it neither confirms the wagnerian income public expenditure nor the keynesian public expenditure national income view the paper recommends that two variables be treated as jointly dependent in both the public finance and macroeconometric studies

private sector shrinkage and the growth of industrialized economies reply further tests and thoughts on the oecd data lead me to conclude that if anything my 1986 paper underestimated the magnitude of the inverse relation between economic growth and government size if one takes the nominal based measure of government scale as advised by saunders the significance levels coefficient magnitudes and goodness of fits improve over what i found with my initial investigation i would suggest that saunders reconsider his reluctance to believe that the size of the public sector is unrelated to economic growth in oecd countries over this time period

an econometric test of wagner s law for six countries based on cointegration and error correction modelling techniques the present study empirically examined five different versions of wagner s law by employing annual time series data on six countries over the period 1951 1996 three countries are part of the emerging industrialized countries of asia south korea taiwan thailand and three are industrialized countries japan usa and the united kingdom the analysis is an advance over previous work in two ways first the stationarity propertities of the data and the order of integration of the data are empirically investigated using the augmented dickey fuller adf and the kwiatkowski et al journal of econometrics 1 1992 kpss tests and second the hypothesis of a long run relationship between income and government spending is tested using bivariate cointegrated systems and employing the methodology of cointegration analysis as suggested by johansen journal of economic dynamics and control 12 1988 and johansen and juselius oxford bulletin of economics and statistics 52 1990 the results indicate that

does globalization affect growth evidence from a new index of globalization the study develops an index of globalization covering its three main dimensions economic integration social integration and political integration using panel data for 123 countries in 1970 2000 it is analysed empirically whether the overall index of globalization as well as sub indexes constructed to measure the single dimensions affect economic growth as the results show globalization indeed promotes growth the dimensions most robustly related with growth refer to actual economic flows and restrictions in developed countries although less robustly information flows also promote growth whereas political integration has no effect

fiscal decentralization and government size numerous studies have attempted to model the possible factors contributing to universal growth in public sectors this paper analyzes one device that appears capable of controlling some of that growth fiscal decentralization the results reported here also support the use of monopoly government assumptions in models of public policy

assessing ricardian equivalence this paper reviews the literature on ricardian equivalence this hypothesis may be interpreted as a generalisation to the short and the long run of the theories which put no weight on the real effects of public policies on aggregate demand we argue that ricardian equivalence relies on both permanent income hypothesis and the fulfilment of the intertemporal government budget constraint the theoretical literature emphasises several reasons for departures from this hypothesis however the empirical literature is inconclusive when ricardian equivalence is tested in a life cycle framework the hypothesis is usually rejected while when the empirical analysis is based on optimising models it is usually accepted

a bound testing analysis of wagner s law in nigeria 1970 2006 this study tests wagner s law the tendency for government activities to expand along with economic expansion for nigeria using annual time series data between 1970 and 2006 it adopts the bounds test approach proposed by pesaran et al 2001 based on unrestricted error correction model uecm and toda and yamamoto s 1995 granger noncausality tests empirical results from the bounds test indicate that there exists no long run relationship between government expenditure and output in nigeria in addition toda and yamamoto s 1995 causality test results show that wagner s law does not hold for more than the period being tested rather we found a weak empirical support in the proposition by keynes that public expenditure is an exogenous factor and a policy instrument for increasing national income

off budget activities of local government comment bennett and dilorenzo have provided evidence that limitations on taxes and spending induce a proliferation of special purpose local government they conclude that the effects on spending were less than originally supposed whatever the effects on total spending a very important effect on the limitations is an induced change in the fiscal constitution of local government using a public choice approach this institutional change was found to have certain desirable features

upsetting national priorities the reagan administration s budgetary strategy we use simulations based on a multiequation model of federal budgetary outcomes to assess the reagan administrations impact on the federal budget during fiscal years 1982 86 reagan s aggregate budget priorities represent a significant departure from the priorities of prior postwar administrations the bulk of this shift in priorities had occurred by fiscal 1984 defense spending and uncontrollable domestic spending were higher and spending on domestic controllable programs lower under reagan than they would otherwise have been the distinctiveness of reagan s budgetary priorities can be attributed to his tax cuts and far from a strategy of starving the budget by reducing revenues to a failure to allow fiscal pressures to restrain spending the model projects that without tax cuts reagan s predecessors would have spent no less on defense than reagan cutting taxes increased the deficit by about 400 billion cumulatively during fiscal years 1982 86 and reduced expenditures by roughly 30 billion

tax and spend or spend and tax an inquiry into the turkish budgetary process for resolving the budget deficit problem some economists have advocated spending cuts while others support either tax increases or tax cuts this paper investigates the interrelationship between the two fiscal variables for turkey using bivariate and multivariate cointegrating models the engle granger and johansen tests consistently support the existence of one nonzero cointegrating vector representing a stable long run relationship between government spending and revenues in turkey furthermore the multivariate error correction model suggests that taxes unidirectionally granger cause negative changes in spending in accordance with the buchananwagner hypothesis thus from the perspective of policy making and the deficit solution debate raising taxes in turkey is perhaps the optimal solution to the current budget deficit predicament contemporary economies perhaps without exception have been plagued with huge and escalating government budget deficits these deficits are expected to have adverse economic consequences including high real interest rates slow capital formation and high unemployment rates moreover to the extent that the deficit is financed through the issuance of government bonds the recurrent large deficits have further worsened the public debt problem which threatens the well being of numerous countries both developed and developing therefore researchers and policymakers have expended enormous efforts attempting to analyze the deficit problem and to suggest ways to resolve it some for example advocate cuts in government spending rather than tax increases as the optimal solution to the deficit dilemma they reason that governments often spend all that they receive in taxes and perhaps much more under this line of reasoning raising taxes would simply induce more spending leaving the deficit unchanged or even higher others however deny this implied tax and spend nexus and argue that it is taxes that adjust gradually to spending under this latter scenario tax increases will not lead to higher spending and thus could be used as an effective deficit cutting measure along with spending cuts still other researchers posit that changes in spending and taxes could occur simultaneously therefore focusing on one component of the government budget while ignoring the interdependence with the other component would have an ambiguous overall effect on the deficit

autoregressive modelling and money income causality detection abstract a step wise procedure based on granger s concept of causality and abaike s final prediction error criterion is suggested as a practical means to identify the order of lags of each variable in a multivariate autoregressive process the model seems useful because it can serve as a reduced form formulation to avoid imposing often spurious or false restrictions of the model it also provides a reasonably powerful test of causality the idea is applied to u s postwar money and income data it is found that between m1 and gnp a bivariate feedback model fits the data best between m2 and gnp a one way causal model from money to income performs better diagnostic checks applied to our model seem to indicate the adequacy of our approach

multivariate exogeneity tests and poverty abstract many recent studies presume direction of the relationship between poverty and other economic factors is one way that is they assume that the various economic phenomena cause or affect poverty and that there is no feedback however if feedback is present it is possible that the level of poverty or the perception of poverty may not only impact public policy decisions aimed at eradicating poverty but may have indirect effects on other economic variables as well we test that hypothesis in this paper using multivariate exogeneity tests

testing wagner versus keynes using disaggregated public expenditure data for canada this paper attempts to test wagnerian versus keynesian hypotheses by examining the relationship between national income and total public expenditure as well as its various components for canada during the period 1950 1995 engle and granger s two step cointegration and error correction techniques are employed to test these two hypotheses the results of this study support both the hypotheses when tested with broader aggregate expenditure data i e total government current expenditure ce and total current expenditures on goods and services cegs although the results of this study do not support the existence of any long run relationship between gdp and the disaggregated public expenditure variables they do support the existence of short run causation implying that national income may be causing or caused by a component of the total government current expenditure in the short run

government expenditures and revenues evidence from asymmetric modeling 1 introductionexamining the empirical relationship between government revenues and expenditures is a crucial step in understanding the future path of the budget deficit four alternative explanations have been used to describe the relationship between these variables in the budgetary process i the tax and spend hypothesis ii the spend and tax hypothesis iii the fiscal synchronization hypothesis and iv the institutional separation hypothesis the issue of which hypothesis best describes the nature of the budgetary process has yet to be resolved in the literature however existing research has implicitly assumed that the state of the budget and whether or not the budget deficit or surplus is worsening or improving does not matter we argue that government decision makers may take these factors into account when determining expenditures and tax policy as such this article reexamines the tax spend debate by using a more robust econometric technique that allows for asymmetry in the relationship between revenues and expenditures until now the empirical evidence on the tax spend debate has focused almost exclusively on two conventional econometric techniques depending on the cointegrating properties between revenues and expenditures these techniques are based on either variations of the unrestricted vector autoregression uvar or the vector autoregression error correction model ecm 1 if for example the two budgetary variables are not cointegrated then the application of causality2 tests requires the use of stationary variables in the uvar model 3 on the other hand if the two budgetary variables are cointegrated then the application of causality tests requires an ecm specification it is important to note that the ecm specification implicitly assumes that the adjustment process of expenditures and revenues due to disequilibrium between the variables is strictly symmetric indeed if the adjustment is asymmetric then the symmetric adjustment implicitly assumed in the conventional techniques to ascertain causality implies model misspecification this specification error may lead to misguided and perhaps inappropriate fiscal policy decisions accurate estimation of the revenue and expenditure process is especially important as changes in taxes and spending alter incentives for work investment and productive activity cea 2004 thus the anticipated behavioral responses of households and businesses may be better captured by more general models that allow for asymmetry in the tax spend relationship to this end this article examines the existence of cointegration between revenues and expenditures and the corresponding ecm specification by using the recently developed techniques of asymmetric modeling in particular we employ the threshold autoregression tar and momentum threshold autoregression m tar models developed by enders and granger 1998 and enders and siklos 2001 within the context of these models we shed new light on whether budget surpluses versus budget deficits or an improving budget versus a worsening budget have asymmetric effects on the dynamic behavior of expenditures and revenues there is an a priori rationale for modeling asymmetry in the budget and for the response of its components to disequilibrium this rationale can be categorized into four factors first the fiscal policymakers may respond differently to a deviation of the deficit or surplus from its long run trend one would expect for example that the response would be more aggressive if the deficit was greater than its long run trend than if it was less than its trend second it is widely acknowledged that there is a very close connection between the budget and the business cycle through automatic fiscal stabilizers and discretionary fiscal measures to the extent that the business cycle is asymmetric the associated change in the budget may also be asymmetric

economic growth and the expanding public sector a reexamination utilizing a granger causality approach the authors test whether there has been a causal rela tion between public sector growth and real economic growth rates for the oecd countries special emphasis is laid on feedback effects from economic growth to government growth that result from macroeconomic policy the authors find that government growth has had mixed effects on economic growth rates positive for some countries and negative f or others however for the majority of the oecd countries there was no discernable impact of government growth on the rate of real econo mic growth copyright 1988 by mit press

off budget activities of local government the bane of the tax revolt this paper has demonstrated that the tax revolt of the 1970s has not been as successful in reducing the level of state and local government expenditure as preliminary empirical findings indicate and that the rate of increase in state and local public spending is likely to be far greater than previously believed the evidence presented here shows clearly that constitutional and statutory limitations on the taxing and spending powers of local governments have led to a massive amount of off budget spending and borrowing the debt issued by off budget enterprises is larger and growing at a much faster rate than the voter approved debt issued by state and local governments and has been since 1975 thus even though statistics on property taxation and expenditure may indicate a slow down in the growth of local taxation the true cost of local government may continue to increase at previous rates although this is an empirical question which we are not yet able to address off budget enterprises are heavily subsidized by local state and federal governments these subsidies represent a hidden tax liability to present and future generations of taxpayers in addition the debt and expenditures of obes contribute substantially to the crowding out of private spending and investment

tax and spend spend and tax or fiscal synchronization new evidence for ten countries cointegration and vector autoregression are used to test the tax and spend spend and tax and fiscal synchronization for ten countries using annual time series data over the period 1951 to 1996 three of them are part of the newly industrialized countries of asia south korea taiwan and thailand and seven are industrialized countries australia canada japan new zealand south africa uk and the usa this paper includes gdp as a control variable into the model like baghestani and mcnown 1994 ross and payne 1998 and koren and stiassny 1998 the johansen 1988 and johansen and juselius 1990 cointegration test results indicate that these three variables are cointegrated with two cointegrating vectors for south korea one vector for australia canada south africa taiwan uk and the usa and no vector for japan new zealand and thailand the results from granger causality tests suggest unidirectional causality running from revenues to spending supporting the tax and spend hypoth

monetary vs credit aggregates an evaluation of monetary policy targets the past decade was characterized by increased emphasis upon monetary aggregates as intermediate targets for monetary policy although growth rate ranges were specified for both narrow and broad monetary aggegates as well as for bank credit the primary focus of the federal reserve was on the growth rate of narrow money however some policy makers 19 have recently expressed doubt about the viability of using narrow money as an intermediate target in particular it has been argued that recent financial innovations such as the introduction of the various now accounts the proliferation of money market mutual funds and the adoption of cash management techniques by both firms and consumers to name a few have distorted the ml1 gnp relationship thereby raising the question of whether broader monetary aggegates or even credit aggregates might bear a closer relationship to income furthermore the federal reserve has recently announced growth rate target ranges for a broad credit aggregate in addition to growth rate ranges for ml and m2 2 friedman 7 8 provides a general discussion of these issues while modiglianipapademos 18 provide a theoretical analysis of the conditions under which a credit aggregate is preferred to a monetary aggregate as an intermediate target however nothing conclusive can be said at the theoretical level since the choice between money and credit aggregates depends upon the true underlying structure of the macroeconomy hence the choice among money and credit aggregates is an empirical issue the aim of this paper is to provide evidence on the issue of credit aggregates versus monetary aggregates as intermediate targets for monetary policy the paper evaluates the characteristics of several monetary and credit aggregates in terms of two attributes of a

expenditures and receipts testing for causality in state and local government finances the results of our tests indicate similarities between the expenditure tax receipt relations of state governments to those previously reported for the federal government in manage and marlow 1986 the results reported here indicate support for the hypothesis that tax receipts cause expenditures at the state level of government for tests utilizing symmetric lag structures ranging from three to five years state expenditures appear to follow state tax receipts for the shortest lag length 2 2 the determination of bidirectional causality does not make us reject the hypothesis that higher spending levels result from higher revenue levels rather the causality appears to be in both directions for the shortest lag length

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

the causal factors of government expenditure growth in greece 1950 80 the notion of causal relationships is the basis on which the empirical testing of theoretical propositions rests this paper considers the risks from the wrong identification of causal relationships and then by using the pierce haugh test attempts to establish the correct causal patterns between various groups of government expenditures within the context of the greek economy from 1950 to 1980 and other variables which have appeared in the literature of the determinants of government expenditure growth

controlling leviathan through tax reduction our paper seeks the strategy that allows the greatest ability to reduce public sector size within a political environment that does not want us to directly set limits on public sector size tax reduction through its quid pro quo effect offers high tangibility to taxpayers and may raise political power of groups that seek both tax reduction and greater opposition to lobbies that seek spending increases for their narrowly defined interests moreover as manage and marlow 1986 argues since the political response to balanced budget rules is likely to raise taxes this political bias of tax hikes suggests that balanced budget rules are offered as a means of changing the funding mix and not the actual budget constraint of government

an examination of the causal relationship between government spending and revenue a cointegration analysis this paper tests the validity of the proposition that there is a causal relationship between government expenditure and government revenue for greece over the period 1957 1993 the empirical analysis employs tests of cointegration as pre tests for granger tests of causality the empirical evidence suggests that there is a long run relationship between government spending and government revenue and expenditures cause revenues

causality analysis and multivariate autoregressive modelling with an application to supermarket sales analysis abstract this paper describes a modelling methodology for multivariate stochastic processes the concept of multiple causality is discussed and a procedure to detect multiple causality is suggested the data of a major canadian supermarket is analyzed and a multivariate autoregressive model for this supermarket is constructed and estimated several empirical findings are reported

budget balance through revenue or spending adjustments abstract the paper provides a historical perspective on the issue of whether budget deficits are typically eliminated by increased taxes or by reduced spending by examining u s budget data from 1792 1988 i conclude that about 50 65 of all deficits due to tax cuts and about 65 70 of all deficits due to higher government spending have been eliminated by subsequent spending cuts while the remainder was eliminated by subsequent tax increases in contrast to previous studies the empirical analysis uses error correction models in a way that the intertemporal budget constraint is imposed in the estimation stage

rational pricing of internet companies we apply real options theory and capital budgeting techniques to the problem of valuing an internet company we formulate the model in continuous time form a discrete time approximation estimate the model parameters solve the model by simulation and then perform sensitivity analysis we report that depending on the parameters chosen the value of an internet stock may be rational if growth rates in revenues are high enough even with a real chance that a company may go bankrupt if the initial growth rates are sufficiently high and if this growth rate contains enough volatility over time then valuations can reach a level that would otherwise appear dramatically high in addition the valuation is highly sensitive to initial conditions and exact specification of the parameters which is consistent with observations that the returns of internet stocks have been strikingly volatile

testing for causality between government spending and taxation in the past few years the public sector deficit in greece has reached alarmingly high levels in view of the various hypotheses about the relation between government spending and revenues we test for causality between these two determinants of public deficit

on the difficulty of eliminating deficits with higher taxes some canadian evidence government budget deficits have increased along with government revenues from direct and indirect taxation both in absolute amounts and as a share of national income in canada as well as in several other countries especially since the 1960s this phenomenon also has coincided particularly since 1980 with skepticism over the notion that government deficit spending stimulates economic growth and employment instead many now expect deficits to produce negative effects on economic activity including high real interest rates reduced real capital formation and production increased unemployment and possible long term inflation 2 these expectations have produced a near concensus on the need to reduce government budget deficits but not on the means of achieving that goal some advocate reductions in government spending as the optimal solution while others call for increases in taxation to raise revenue although either policy in principle may achieve the same result for the deficit they arise from different theories of the determinants of government spending in particular those who advocate expenditure cuts suggest that increased taxation would increase government spending more than it would reduce the deficit arguing that there is a causal direction from increased tax revenues to increased government expenditures although the taxation spending causality hypothesis has assumed increased prominence over the last decade 3 little statistical testing has been done for canada studies by manage and marlow 18 and ram 21 lend support to the argument that expenditures are more responsive to revenues than the reverse on the basis of u s data indeed ram s work contradicts the earlier conclu

were japanese stock prices too high abstract this paper asks whether market fundamentals can explain the recent run up and decline of japanese equity values and price earnings ratios accounting differences explain about half of the long run disparity between u s and japanese p e s for example if japanese firms used u s accounting rules the japanese p e ratio would have been 32 6 not 53 7 in 1989 accounting differences cannot however explain the doubling of this ratio in 1986 nor its decline in 1990 similarly we are unable to isolate changes in required stock returns or growth expectations that are large enough to explain recent japanese stock price movements

government revenue and government expenditure nexus evidence from developing countries the relationship between government revenue and government expenditure has attracted a lot of interest given its policy relevance particularly with respect to budget deficits the goal of this paper is to investigate evidence for causality between government revenue and government expenditure within a multivariate framework by modelling them together with gross domestic product for 12 developing countries our application of the toda and yamamoto 1995 test for granger causality reveals support for the tax and spend hypothesis for mauritius el salvador haiti chile and venezuela for haiti there is evidence for the spend and tax hypothesis while for peru south africa guatemala uruguay and ecuador there is evidence of neutrality

do revenues or expenditures respond to budgetary disequilibria the post world war ii increase in the size of the federal government has led to a number of theoretical and empirical investigations of the sources of this growth in particular economists have questioned whether increases in the size of the federal budget tend to be initiated by changes in expenditures followed by revenue adjustments by the reverse sequence or both friedman for example argues that governments adjust expenditures to the level of revenues so that control of taxation is essential to limit growth in government 13 alternatively the spend and tax model posits that revenues will be adjusted to finance any politically chosen level of expenditures a third perspective reflecting the institutional separation of allocation and taxation functions of the federal government hypothesizes the independent determination of revenues and expenditures the goal of this investigation is to test these three alternative theories of the budgetary process for the united states

variances of security price returns based on high low and closing prices in a recent paper garman and klass 1980 studied the problem of estimating capital asset price volatility parameters developing an idea first introduced by parkinson 1980 they argue that improved volatility measures can be obtained by taking into account the daily high low and opening prices in addition to the traditionally used closing prices this paper is concerned mainly with testing the empirical validity of different volatility estimators based on high low and closing prices

on the specification of granger causality tests using the cointegration methodology the application of granger causality tests to macroeconomic time series frequently necessitates filtering the data to induce stationarity if the relevant variables are cointegrated granger causality tests are misspecified if applied in standard vector autoregressive format to differenced data a common application is illustrated

expenditures and receipts in state and local government finances reply it is worth repeating that causality testing is a very complex task the diversity of views on interpreting the definition of causality and on the methods for testing causality highlight this issue in our study we cite an excellent article which provides a detailed critique of various problems associated with causality tests see conway et al 1984 it would appear that chowdhury s comment draws very strong conclusions and fails to consider some of the complex theoretical issues regarding causality tests as well as important data problems pertaining to state and local governments moreover we find it somewhat curious that given the strong similarities in our two studies chowdhury prefers to dwell on the mechanics of an alternative technique rather than concentrate on the fact that his alternative technique yields supporting results to our 1987 paper on the tax spend hypothesis

the effect of emission taxes and abatement subsidies on market structure abstract emission taxes and abatement subsidies are considered to be efficient measures for environment protection the purpose of this paper is to quantify their effects on industry output firm output and on the number of firms in the industry three types of market structure are under discussion perfect competition oligopoly and a dominant firm with a competitive fringe it turns out that emission taxes and abatement subsidies affect the structure of the polluting industry in opposite ways while the effects on industry s emissions are similar in direction but different

public expenditure growth in greece and portugal wagner s law and beyond in the tradition of wagner s law this study examines the relationship between aggregate income and public expenditures in greece and portugal during the years 1958 85 unlike more conventional specifications our analysis focuses on the movement of different componenets of public expenditures permanent income relative prices stabilization policy and socio political factors emerge as thomain determinants of public expenditures while the results reveal significant difference in responses to these determinants across components of expenditures and between the two countries

free trade agreements and world obesity we study the causal link between trade openness via free trade agreements ftas and obesity rates when applying a difference in differences approach by exploiting the year a country entered a free trade agreement with the united states during the period 1990 2016 we find a positive and causal impact of ftas on obesity rates which are statistically and economically significant we show that our findings are robust to placebo tests the use of synthetic control methods and a maximized sample furthermore we show that when using an event studies approach the equal trends assumption holds
