fiscal shocks and budget balance persistence in the eu countries from central and eastern europe this article analyses the time series properties of the fiscal balance in the 10 eu countries from central and eastern europe the persistence of the fiscal balance is analysed by means of unit root tests that account for possible nonlinearities and structural changes the linear and nonlinear unit root tests find only mild evidence in favour of the stationarity hypothesis with asymmetric effects present in a few cases after controlling for structural changes in the data generation processes dgps the results point to stationarity of the series thus in spite of relatively steady headline figures the budget balance processes in the eu countries from central and eastern europe exhibit substantial instability

a model based indicator of the fiscal stance we argue that the conventional approach to assessing the fiscal stance based on econometric tests of the government present value budget constraint pvbc is of limited practical use we propose an alternative measure that focuses on short run fluctuations in the fiscal stance namely a model based indicator that compares a target level of the debt gdp ratio at a given point in the future with a forecast based on the government budget constraint gbc where the forecasts are obtained using a recursively estimated var by log linearising the gbc the index can be decomposed into the various different components of which it is comprised using data from 1970 to 2011 we conduct a detailed time series study of the fiscal stances of four countries the united states the united kingdom germany and greece and we calculate the index for 11 other eu countries for most countries the index shows that their fiscal stances vary from being too loose to too tight almost without exception the index drops sharply from 2007 showing the harmful effect on their fiscal stances of the recent recession

testing intertemporal budget constraints theory and applications to u s federal budget and current account deficits this paper extends previous tests of intertemporal budget balance and present value relationships by expanding the set of allowable deficit processes and by deriving a testable condition that is sufficient to ensure intertemporal budget balance as long as the expected discount rate is strictly positive using these tests the authors find that both the postwar federal budget deficit process and the process governing accumulation of u s assets by foreigners are consistent with intertemporal budget balance copyright 1991 by ohio state university press

common trends the government s budget constraint and revenue smoothing abstract the requirement that the government s budget be balanced in present value terms is shown to be equivalent to the condition that government expenditures inclusive of interest tax receipts and seignorage be cointegrated the condition is in fact stronger requiring that the deficit inclusive of interest be stationary stationarity of the net of interest deficit is neither necessary nor sufficient for intertemporal budget balance however it does have implications for barro s tax smoothing hypothesis data for the period 1890 1986 are consistent with intertemporal budget balance but not with tax smoothing

the u s evidence on optimal taxation over time abstract this paper considers a tax rule in which a uniform tax rate over time becomes optimal its implications are that 1 changes in the tax rate should arise only when there are changes in permanent government expenditures and 2 no variable other than permanent government expenditures should be of any value in predicting the tax rate these implications are tested using u s data for 1937 82 empirical results of the tests reveal that in addition to responding to permanent government expenditures the tax rate also responds to temporary defense purchases the general price level and a time trend

the sustainability of government deficits implications of the present value borrowing constraint this paper introduces a new methodology for evaluating the sustainability of fiscal policy the new methodology is distinguished from most existing tests in two important respects first it allows for stochastic real interest rates and second it is both necessary and sufficient results from the application of the new test suggest that recent fiscal policy in the united states has not been sustainable the paper contrasts its findings with those of james d hamilton and marjorie a flavin 1986 copyright 1989 by ohio state university press

assessing long term fiscal developments a new approach abstract we use a new approach to assess long term fiscal developments by analyzing the time varying behaviour of the two components of government spending and revenue responsiveness and persistence a feature not captured by automatic stabilisers we are able to infer about the sources of fiscal deterioration improvement drawing on quarterly data we estimate recursively these components within a system of government revenue and spending equations using a three stage least square method for eight european union countries plus the us the results suggest that significant changes in the fiscal stance including those related to the current crisis are reflected in the estimates of persistence and responsiveness

bubble finance and debt sustainability a test of the government s intertemporal budget constraint this paper tests whether the government s budget is intertemporally balanced in a number of ec countries by applying a method first developed to detect speculative bubbles in financial markets the test aims to establish whether the government can engage in buble finance and is based on a comparison between two sets of estimates the first is obtained directly by regressing the stock of outstanding debt on a distributed lag of the primary surplus the second is obtained indirectly from a pair of equations one relating the current debt stock to next period s primary surplus and debt stock the other specifying an ar process for the primary surplus in the presence of a bubble only the first set of estimates is inconsistent and hence the two sets differ it is found that the null of no bubble can be rejected in the cases of italy germany denmark and greece implying that the government is not intertemporally solvent in these countries the other ec member states appear to be on a sustainable path

price elasticity of groundwater demand attenuation and amplification bias due to incomplete information measurement errors in both human and natural components of agricultural and environmental systems can be as much a source of estimation bias as omitted variables selfselection simultaneity and reverse causality nonetheless partly because of difficulties in obtaining data there is less literature on measurement error problems than on other endogeneity problems this article examines estimation bias in the price elasticity of groundwater consumption for irrigated agriculture on the intensive margin the price at issue is for the energy used in pumping and pressurizing water for delivery lacking the precise unit irrigation cost previous studies imputed irrigation costs we first consider groundwater irrigation costs and identify factors that can cause measurement errors in the process of imputation under incomplete information about the determinants of irrigation costs we follow this by systematically analyzing the potential bias caused by measurement errors using econometric theory along with monte carlo simulations where appropriate we then quantify actual measurement errors making use of a unique dataset in which energy and groundwater consumption data are matched for individual observations finally we compare regression results using exact irrigation costs as opposed to imputed ones we find evidence of substantial measurement errors resulting in attenuation and amplification bias in the price elasticity of irrigation water consumption on the intensive margin our results indicate that measurement errors in irrigation costs can lead to misleading policy implications related to water and energy pricing as a tool to conserve water we also show that estimating the energy price elasticity of groundwater use is not as straightforward as previously thought

the role of intergovernmental aid in defining fiscal sustainability at the sub national level the concept of fiscal sustainability has become increasingly used over the last 20 years however much of the literature on fiscal sustainability at the sub national level ignores the role of intergovernmental fiscal relations to address this gap this paper discusses a sufficient condition for sub national fiscal sustainability and examines the importance of intergovernmental aid in determining that sustainability using panel data of counties and municipalities in the us and using unit root and cointegration analytic techniques this paper finds different levels of fiscal sustainability between counties and municipalities we also find that intergovernmental aid plays an important role for fiscal sustainability for both counties and municipalities

inflation its variability and consumption in selected latin american countries abstract the aim of this paper is to estimate the impact of inflation on consumer expenditures in argentina brazil and chile attention is also given to the impact of uncertainty about inflation and to the role of liquid assets

is the budget deficit too large yes specifically we find that recent spending and taxing policies of the government if continued violate the government s intertemporal budget constraint as a result government spending must be reduced and or tax revenues must be increased these conclusions are based on tests of whether government spending and revenue are cointegrated in addition to examining real spending and revenue we also normalize these variables by real gnp and population for a growing economy these normalized measures are perhaps more pertinent we also test and find support for the hypothesis that deficits have become a problem only in recent years

a private property rights regime for the commons the case for groundwater we compare the social welfare of pumping groundwater under central optimal control to that obtained under a private property rights regime in which firms are granted tradeable permits to the in situ groundwater stock when firms are risk averse both regimes are suboptimal and the matter of which regime yields greater welfare is an empirical one when firms are risk neutral central control dominates the private property rights regime still a stochastic dynamic programming model of madera county california demonstrates that even in this case the private property rights regime is a promising alternative to central control

improved estimates and forecasts of error correction models in economics abstract this paper is concerned with improved estimation and better forecasting of major economic activity within the context of error correction ec models as pioneered by sargan in 1964 and extended by numerous economists over the past three decades a new and general econometric methodology with superior average mean squared errors mse for ec models is introduced and for illustration applied to the estimation and forecasting of private consumption and demand for money in australia for the period 1960 1992 the improvement in terms of historical and ex post forecasting mse of our new methodology over the conventional statistical approaches currently in use for ec models is found to be up to 15 43

sustainability of the deficit process with structural shifts this article discusses the condition for deficit sustainability and searches for shifts in the structure of u s deficit policy i show that contrary to the current literature cointegration between revenues and expenditures inclusive of debt payment is not a necessary but a sufficient condition for a strict interpretation of deficit sustainability the necessary condition requires that debt grow slower than the borrowing rate for tests on structural shifts i use a test for structural change that searches for shifts in the rank of the cointegrating matrix i find that there is a shift in deficit policy in the early 80s so that cointegration between revenue and expenditure inclusive of interest payments holds only up to 1980 i show however that the deficit process is still sustainable despite the failure of cointegration in the 80s the finding of shifts in the deficit process is more uncertain when i normalize by gross national product or population but the deficit is shown to be sustainable regard

the demand for irrigation water in the high plains of texas 1957 80 a new method of calculating groundwater pumpage is used to estimate water demand these results are used via the gisser sanchez model to show that pumpage regulation is unlikely to be beneficial in the texas high plains a sensitivity analysis is performed on present value profits under optimal control and competitive schemes using different water demand slope and intercept values the results indicate that the gisser sanchez rule is useful in determining the divergence in pumpage time paths and percentage difference in profits under the two schemes but it is not insightful in determining the nominal difference in profits

are bond financed deficits inflationary a ricardian analysis this paper considers the possible theoretical validity of the following monetarist hypothesis that a constant positive government budget deficit can be maintained permanently and without inflation if it is financed by the issue of bonds rather than money the question is studied in a discrete time perfect foresight version of the competitive equilibrium model of sidrauski modified by the inclusion of government bonds as a third asset it is shown that the monetarist hypothesis is invalid if the deficit is defined exclusive of interest payments but that it is valid under the conventional definition it is also shown that the stock of bonds can grow indefinitely at a rate in excess of the rate of output growth provided that the difference is less than the rate of time preference these formal conclusions do not take account of possible limitations on taxing capacity arising from default incentives that tend to grow with the stock of bonds

on the limitations of government borrowing a framework for empiricaltesting this paper seeks to distinguish empirically between two views on the limitations of government borrowing according to one view nothing precludes the government from running a permanent budget deficit paying interest due on the growing debt load simply by issuing new debt an alternative perspective holds that creditors would be unwilling to purchase government debt unless the government made a credible commitment to balance its budget in present value terms we show that distinguishing between these possibilities is mathematically equivalent to testing whether a continuing currency inflation might be fueled by speculation alone or is instead driven solely by economic fundamentals empirical tests which have been developed for this economic question lead us to conclude that postwar u s deficits are largely consistent with the proposition that the government budget must be balanced in present value terms this abstract was borrowed from another version of this item

us deficit sustainability revisited a multiple structural change approach in this article we re examine the long run sustainability of us budget deficits using bai and perron s multiple structural change approach while the deficit would have been weakly sustainable over the full sample 1947 1 2005 3 strong sustainability would appear only between january 1982 and february 1996

are state and provincial governments tax smoothing evidence from panel data the theory of debt examined here is known variously as efficient taxation over time optimal taxation over time the equilibrium approach to fiscal policy or tax smoothing tax smoothing results when an efficient government fixes tax rates today to minimize the costs of taxation over time given the long run constraint of a balanced budget if the marginal costs of taxation are an increasing function of the amount of resources taxed i e the tax rate then minimization of the total costs of taxation implies that the planned tax rate will be constant over time tax rate changes will be unpredictable and the tax rate will behave as a random walk efficient governments will not adjust tax rates to accommodate temporary changes in expenditures and revenues instead governments will minimize tax rate changes by tax smoothing smoothing tax rates implies that temporary changes in government spending and output result in deficits and surpluses therefore tax smoothing provides a theory of government debt the model is primarily due to barro 1 the goal of this paper is to contribute to our understanding of government debt the focus of this paper is on state and provincial debt or what is generally referred to as state and local debt nearly every state government in the united states has a balanced budget rule however balanced budget rules are not sufficient to rule out tax smoothing as state governments could build up budget surpluses in good times to smooth budgets over the business cycle if state governments are smoothing tax rates then their budget surpluses are endogenous contrary to the state governments provincial governments in canada have no balanced budget rules if provincial governments are smoothing tax rates it could explain the behavior of their budget deficits and surpluses as shown by barro tax smoothing implies that the overall tax rate behaves as a random walk and the tax rate would be a nonstationary time series with a unit root this study examines the tax smoothing hypothesis in two ways first the random walk implication is examined directly by testing the null hypothesis that the tax rate time series has a unit root second if the tax rate behaves as a random walk then changes in the tax rate should be unpredictable from past information if past information can predict tax rate changes this would provide evidence in favor of an alternative hypothesis a rejection of tax smoothing suggests that state and provincial tax rates respond to current

benefits from groundwater management magnitude sensitivity and distribution empirical estimates of benefits from groundwater management are reported for an area in california with heavy reliance on groundwater supplies benefits are quite sensitive to the water demand schedule and interest rate but less sensitive to other parameters however in all cases considered the increases in welfare from groundwater management are less than ten percent tax revenues received under a system of pump taxes are four to five times as large as the benefits from management thus groundwater users gain under a system of quotas but may suffer substantial welfare losses under pump taxes

is the greek budget deficit sustainable after all empirical evidence accounting for regime shifts this article re examines the sustainability of the greek budget deficit by using a formal framework based on the government s intertemporal budget constraint the empirical analysis uses annual data from 1960 to 2011 and employs traditional as well as more recent unit root and cointegration techniques that account for linear and nonlinear effects in fiscal policy actions unlike previous studies the evidence suggests that allowing for structural breaks the greek budget deficit is unsustainable the parameter after the second detected break reflects the structural deficiencies of the greek economy

cointegration and government borrowing constraints evidence for the united states testable implications are derived in a present value borrowing constraint model for the u s federal government critical values for unit root and cointegration tests are calculated with monte carlo studies cointegration techniques are employed to determine whether the government has been involved in perpetual debt financing in recent years the data reject this assertion

excessive deficits sense and nonsense in the treaty of maastricht maastricht s fiscal rules willem buiter giancarlo corsetti and nouriel roubini the maastricht treaty on economic and monetary union in the ec has specified limits on both government debt and fiscal deficits satisfying these criteria is necessary for getting into emu once inside violating these limits will also incur penalties the fiscal requirements especially the debt criterion are much tougher than is required to ensure public sector solvency trying to attain these targets will force the ec initially into substantial deflation and recession failure to correct for real growth inflation and the business cycle makes the nominal deficit a poor basis for any policy or target ambiguity about how fiscal targets will in fact be interpreted might provide a way out but cannot today be relied upon to do so supranational fiscal rules are sometimes claimed to be justified by externalities in national fiscal policies we find this justification wanting both in theory and empirically a better case might be built on the imposition of external commitments to offset domestic political distortions that systematically induce excessive deficits even so we conclude that the fiscal convergence criteria on balance are harmful and should be disregarded or applied very loosely to avoid the risk of serious fiscal overkill

fiscal deficit sustainability of the spanish regions carrion i silvestre j l fiscal deficit sustainability of the spanish regions regional studies the fiscal deficit of the spanish autonomous communities is investigated using non stationary panel data analysis the paper considers the two main approaches in the literature first assessing whether there is a long run relationship between the revenues and expenditures of the autonomous communities and second focusing on the use of fiscal rules the paper shows that it is possible to relate these approaches in a unified framework

international evidence of tax smoothing in a panel of industrial countries a panel of industrial countries is examined for evidence of tax smoothing tax smoothing results when governments minimize tax distortions over time the model provides a positive theory of government debt and is due primarily to barro unit root tests are performed in panel data to test the null hypothesis of nonstationary tax rates panel regressions are then undertaken to test the null hypothesis that tax rate changes are unpredictable and test for evidence of an alternative hypothesis political and economic variables are examined for their ability to predict tax rate changes overall the results cannot reject the null hypotheses and support tax smoothing by national governments

an all encompassing consumption function the australian case abstract the paper reports some empirical findings of the davidson hendry srba and yeo 1978 consumption function fitted to australian quarterly data for the period 1969 3 to 1982 2 the evidence rejects in terms of the maximum likelihood ratio test the unitary differencing and price homogeneity restrictions and supports a simple dynamic forecasting model with unconstrained parameters

groundwater use under incomplete information abstract this paper introduces a game theoretic model of groundwater extraction in a two cell aquifer under incomplete information a novel assumption is that individual users have incomplete knowledge of the speed of lateral flows in the aquifer although a user is aware that his neighbor s water use has some influence on his future water stock he is uncertain about the degree of this impact we find that the lack of information may either increase or decrease the rate of water use and welfare in a two period framework the relevant characteristic is the ratio of the periodic marginal benefits of water use depending on whether this ratio is convex or concave the average speed with which the aquifer is depleted decreases or increases when users learn more about the local hydrologic properties of groundwater in principle welfare may decrease even in cases when the groundwater allocation is closer to the efficient groundwater allocation

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

public debt in brazil sustentability and its implications abstract this paper tests sustainability of brazilian public debt in the period 1991 to 2009 and analyzes implications of requiring that the brazilian fiscal policy be primarily committed to the sustainability of the public debt the retrospective analysis utilizes a set of unit root tests and avoids some of the criticism leveled at previous studies by using data which has not previously been used for this purpose and concludes that the public debt was sustainable in the period we consider the prospective analysis is based on the dsge model proposed by jodi gali et al 2007 calibrated for brazil using the conclusions of the retrospective analysis for the fiscal parameters the scenarios produced with the help of the model show that maintaining the sustainability of the public debt is consistent with the monetary policy of inflation targeting we also conclude that it is possible to reduce interest rates to levels below those prevalent at the end of 2010 simultaneously maintaining the stability of the trajectory of the public debt

current issues in the economics of groundwater resource management the issue of groundwater management remains a practical concern in many regions throughout the world while water managers continue to grapple with the question of how to manage this resource in this article we attempt to bring the most advanced and appropriate tools to bear on the issue of resource allocation involving groundwater our objective is to demonstrate the state of the art in the literature on ways to think about this complex resource and to deal with the important economic issues emanating from its complexity we present the conceptual framework within which economists examine the elements interacting in the management of groundwater resources indicate why the role of the market is limited with respect to the price of this very complex resource and point to the mechanisms that can pull competitive groundwater price and quality graded quantity of groundwater in line with their equilibrium levels in particular we critically review economic models of groundwater use examine the potential for groundwater management discuss the difficulties encountered in the estimation of the relevant control variables of such models and identify the advantages and limitations of the instruments devised for the efficient use allocation of this resource finally we argue that devised regulatory schemes usually ignore the information and knowledge needed for their implementation and we suggest a core of conditions necessary for successful groundwater management reforms

are stationarity and cointegration restrictions really necessary for the intertemporal budget constraint abstract time series related to fiscal and external deficits are commonly subjected to stationarity and cointegration tests to assess if the deficits are sustainable such tests are incapable of rejecting sustainability the intertemporal budget constraint proves to be satisfied if either the debt series or the revenue and with interest spending series are integrated of arbitrarily high order i e stationary after differencing arbitrarily often revenues and spending do not have to be cointegrated rejections of low order difference stationarity and of cointegration are thus consistent with the intertemporal budget constraint error correction type policy reaction functions are suggested as more promising for understanding deficit problems

seigniorage and tax smoothing in the united states 1914 1986 abstract when monetary and fiscal authorities cooperate to minimize the distortionary costs of financing an exogenous stream of government expenditures barro s tax smoothing model implies a long run relationship between tax revenues and inflation previous empirical tests of this relationship are reinterpreted in light of recent work on cointegration and are shown to hold only when stochastic temporal variation in the excess burden of taxes and seigniorage is transitory in nature a new test that holds in the presence of nonstationary disturbances is developed and applied annual u s data from the period 1914 to 1986 reject the revenue smoothing hypothesis

competitive versus efficient extraction of a common property resource the groundwater case abstract in this paper socially optimal and private extraction of a common property aquifer are compared open loop equilibrium and feedback equilibrium in linear strategies have been computed to characterize private extraction the use of these two equilibrium concepts allows us to distinguish between cost and strategic externalities as long as the open loop solution captures only the cost externality and the feedback solution captures both the results show that strategic behaviour increases the overexploitation of the aquifer compared to the open loop solution however if the groundwater storage capacity is large the difference between the socially optimal and private extraction the latter characterized by a feedback equilibrium is negligible

government budget deficits and trade deficits are present value constraints satisfied in long term data abstract we test whether long term data from the u s and u k are consistent with the intertemporal government budget constraint and external borrowing constraint both individually and simultaneously a very strong test is provided by our focus on whether the present value constraints pvcs continue to hold despite unusual events such as wars that cause a structural break in the short run dynamic behavior of the variables we find that the pvcs hold over the whole sample period the data also indicate that the pvcs continue to hold following events that cause a structural break in the short run dynamics

fiscal policy rules and the sustainability of public debt in europe the sustainability of public debt is interpreted as the result of the interaction of fiscal policy with the economic environment and not as a statistical concept as in most of the recent literature if debt is not to explode over time policymakers have to respond to the changing conditions in the macroeconomic environment this article defines the conditions that will ensure compliance of fiscal policy with the intertemporal budget constraint in the context of europe s fiscal policy rules the empirical part of the article reveals that european public debt is sustainable in this respect but questions regarding long run liquidity requirements remain unresolved

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

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

explaining u s federal deficits 1889 1998 i introduction seater 1993 attempted to provide a common basis for assessing empirical studies of the effects of deficit spending he concluded that evidence of the existence of appreciable effects of u s deficits on macroeconomic variables is questionable in other words the data do not allow for a confident rejection of ricardian equivalence in a world with no macroeconomic effects from deficit spending full information and no distinctions between political and economic markets fluctuations in deficits merely reflect government financing considerations of secondary importance in contrast to this view of the world deficits and surpluses are treated as an important topic in everyday affairs and discourse politicians talk about deficits and surpluses regularly when calling for higher or lower taxes more or less spending revisions in social security funding and other changes in public policy economists and political analysts continue to debate why deficits became a regular feature of federal fiscal management from the late 1960s into the 1990s these debates have spurred divergent theories and conjectures leading to different empirical hypotheses and variables of interest moreover existing empirical studies of the subject have utilized diverse econometric techniques and specifications as a result the competing hypotheses concerning deficit spending have not been tested against one another in a systematic fashion in this article our principal aim is to analyze the different explanations of u s federal deficits jointly estimating competing hypotheses about deficit fluctuations in a generalized reduced form empirical model to achieve this goal we collected and utilized a time series of data running from 1889 to 1998 the apparent paradox between the seemingly innocuous effects of deficits and the political preoccupation with them may owe its existence to one or more reasons limited and noisy information among voters differences between economic and political markets inaccuracy in the measured macroeconomic effects of deficits or other reasons we do not attempt an explanation of why deficits which seemingly exhibit no or small real effects ricardian equivalence could lead politicians and voters to treat deficits as if the ricardian hypothesis were rejected instead we treat explanations of deficits that stem from ricardian premises as one of several hypotheses to be tested ii competing hypotheses we first describe the leading explanations of deficit spending organizing them around common theoretical principles 1 tax smoothing the explanation of deficits which follows directly from a ricardian equivalence theory is the tax smoothing theory developed by barro 1979 2 if deficits generate no real macroeconomic effects and the influences of political institutions and politicians are ignored then optimal public financing considerations govern the use of deficit spending simply put fiscal authorities raise revenue to meet spending needs through income taxation but both spending and income the tax base are subject to uncertain and temporary movements minimization of the deadweight costs of raising a given amount of revenue requires keeping tax rates steady in the face of purely temporary changes in income or spending this is accomplished by running deficits when income is temporarily low or spending is temporarily high and running surpluses in the opposite case imposing a binding no ponzi game npg constraint leads to similar long term behavior of deficits as implied by optimal finance models the npg condition requires that the present value of taxes must equal the present value of spending plus the initial value of debt spending and revenue must share a long term common trend so that primary deficits will be stationary over a long time series deficits and surpluses will offset each other

an investigation of ricardian equivalence in a common trends model abstract to empirically discriminate between ricardian and non ricardian behaviour we have to use a method that distinguishes between expected and unexpected as well as permanent and transitory changes in taxes and government consumption one method that provides these distinctions between different types of changes is the common trends framework used in this paper which is a var model with cointegrating constraints in the empirical study of us data there is some support for the ricardian hypothesis but there are also some deviations from its predictions however the differences do not lend support to a keynesian view of budget deficits but rather to the view of expansionary fiscal contractions this can be motivated theoretically by uncertainty about future taxes in combination with prudent households

fiscal sustainability and monetary versus fiscal dominance evidence from brazil 1991 2000 under a monetary dominant md regime the primary surplus adjusts to limit debt growth permitting monetary policy to be conducted independently of fiscal financing requirements in brazil some evidence favours an md regime for 1995 1997 but not for the decade of the 1990s as a whole while fiscal adjustments of 1999 yielded a primary surplus of about 3 of gdp consistent with solvency a credible md regime would require further adjustments of the primary surplus if debt increases growth falls or interest rates rise

sustainability and comovement of government debt in emu countries a panel data analysis we investigate the sustainability of fiscal policy in a set of 19 european monetary union emu countries over the period 1970 2016 panel unit root tests in the presence of cross section dependence show that the government debt series is stationary indicating that the solvency condition would be satisfied for these countries this confirms the effectiveness of the austerity measures implemented by these member states moreover an unobserved common factor drives the comovement of government debt in the eurozone

assessing the mean reversion behaviour of fiscal policy the perspective of asian countries this article investigates fiscal policy sustainability in 10 asian countries by adopting a battery of unit root tests univariate unit root tests reveal that the fiscal stance in these countries follows a nonstationary process while the opposite conclusion was drawn for the same dataset using the commonly employed panel unit root techniques by utilizing the series specific panel unit root test recently developed by breuer et al 2002 suradf seemingly unrelated regression augmented dickey fuller that allows testing for the presence of nonstationarity within individual cross sections of the panel we found that only cross sections four out of 10 countries in the panel are stationary this means that fiscal deficits in most asian countries are in violation of their intertemporal budget constraint and that the deficits are too large

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

bohn s test of fiscal sustainability of the american state governments the dramatic fall in state revenues during the great recession and the resultant large budget deficits accentuated concerns about state fiscal sustainability i employ a model based approach proposed by bohn 1998 to test for sustainability in this approach a positive and significant reaction of the ratio of primary surplus ratio s to lagged debt constitutes a sufficient condition for sustainability based on a panel of 48 contiguous states 1961 2008 and several model specifications i find robust evidence in favor of sustainability further analysis suggests that the adjustment of the components of s to debt is asymmetric with the revenue side bearing a heavier burden than the spending side the response of s is also found to be asymmetric with respect to the level of debt finally the magnitude of the response is larger in states with a higher degree of fiscal stringency in general and own revenue and no deficit carryover provisions in particular

strategic behavior and efficiency in the common property extraction of groundwater groundwater has always been regarded as a common property resource where entry is restricted by land ownership and private exploitation is inefficient in 1980 gisser and sanchez presented a first estimation of this inefficiency cornparing socially optimal exploitation with private competitive exploitation using a model with linear water demand average extraction cost independent of the rate of extraction and linearly decreasing with respect to the water table level they characterized the private exploitation of the aquifer assuming that farmers are myopic and choose their rate of extraction to maximize their current profits whereas optimal exploitation is obtained by maximizing the present value of the stream of aggregate profits their results show that if the storage capacity of the aquifer is relatively large the difference between the two systems is so small that it can be ignored for practical consideration this result has been called the gisser sanchez rule by nieswiadomy 1985 and it has and important policy implication regulation of the resource does not seem justified since the profits it brings are not very high 1

optimal groundwater extraction under uncertainty and a spatial stock externality we introduce a model that incorporates two important elements to estimating welfare gains from groundwater management stochasticity and a spatial stock externality we estimate welfare gains resulting from optimal management under uncertainty as well as a gradual stock externality that produces the dynamics of a large aquifer being slowly exhausted this groundwater model imposes an important aspect of a depletable natural resource without the extreme assumption of complete exhaustion that is necessary in a traditional single cell bathtub model of groundwater extraction using dynamic programming we incorporate and compare stochasticity for both an independent and identically distributed as well as a markov chain process for annual rainfall we find that the spatial depletion of the aquifer is significant to welfare gains for a parameterization of a section of the ogallala aquifer in kansas ranging from 2 9 to 3 01 which is larger than those found previously over the region surprisingly the inclusion of stochasticity in rainfall increases welfare gains only slightly

are southern poor countries governments more profligate than their northern rich counterparts fiscal criteria and impulse responses this study examines the health of public finances in different geographical regions by emphasising the discrepancies in north versus south and rich versus poor countries the last decade s debt and deficit figures depicting a general fiscal consolidation across regions and income levels show signs of worsening when the fiscal criteria are adjusted for cyclical factors fiscal pressure appears in most countries since the end of the 1990s but has been more persistent in poor countries and in asia the dynamics of governments reaction to debt accumulation reveals however that most regions exhibit consistent anti debt policies to various degrees the exception is the latin american and caribbean region where results suggest a lack of debt fighting policies among income categories rich countries generate the highest primary surpluses when confronted with debt accumulation

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

persistent deficits and the market value of government debt summary this paper investigates whether postwar canadian public financial policy satisfies a borrowing constraint direct tests of the present value relation suggested by this constraint shed light on the sustainability of current policy we examine monthly data on canadian federal government finances using tests for cointegration the finding is that the joint behaviour of real debt and real surpluses is inconsistent with intertemporal budget balance for the government one interpretation of this finding is that the government is systematically paying real returns to bondholders by issuing further debt alternatively bondholders may expect the government to finance future interest payments from a source other than primary surpluses e g the sale of physical assets much empirical macroeconomics is concerned with the effects of public financial policies numerous studies have examined whether such policies affect interest rates inflation or national income and its components these examinations raise the question of the efficacy of government budget deficits they generally assume that a borrowing constraint holds in the public finances some positive theories of public debt creation also make this assumption examples include barro s 1979 history of us federal deficits and sargent s 1986 rationalizations of recent us budgetary policy lucas and stokey s 1983 discussion of optimal taxation also involves this assumption hansen roberds and sargent 1987 outline the testable implications of present value budget balance and hamilton and flavin 1986 investigate the feasibility of recurring deficits by directly testing the us federal government s borrowing constraint such tests seem natural given both the recent boom is testing more complicated first order difference equations in macroeconomics and the widespread discussion of current deficits this paper tests the present value borrowing constraint using recently constructed data on the market value of outstanding canadian federal government debt we use monthly rather than annual as in hamilton and flavin data and conduct tests of univariate integration and of bivariate cointegration to investigate the joint time series properties of debt and deficits one finding is that real debt and real surpluses are integrated processes evidence of their cointegration is mixed and point estimates of the cointegrating vector suggest that the expected real rate of return on debt is negative moreover the surplus measured to include interest payments as government spending is nonstationary these findings are inconsistent

recent trends and structural breaks in us and eu15 labour productivity growth this article examines shifts in labour productivity growth in the us and in europe between 1970 and 2007 based on econometric tests of structural breaks additionally it makes use of time series based projections of labour productivity growth up to 2009 in order to detect breaks depending on confidence intervals of the projections the identification of structural breaks in the us labour productivity growth is far from obvious a statistically significant break is found in the late 1990s only if at least the 97 5th percentile of forecasts materializes in the future which means that despite a clear pick up in productivity growth in the second half of the 1990s the size of the hump is not large enough compared with past variations to make this change a statistically significant break however a significant break point is detected in the mid 1990s for the difference in labour productivity growth between the us and the eu15 even when controlling for the convergence of europe towards the us productivity l

fiscal transfers and fiscal sustainability we examine whether the u s and german state governments pursue sustainable fiscal policies taking into account fiscal transfers using panel data techniques we investigate whether the debt to gdp ratio had a positive influence on the primary surplus bohn model we show that including excluding fiscal transfers changes the results if fiscal transfers are not included in the primary surplus the test results do not indicate that the u s and german state governments pursued sustainable fiscal policies our results also suggest that fiscal transfers were positively related to debt these findings indicate that intergovernmental transfers have implicitly subsidized debts

pareto improving water management over space and time the honolulu case we model welfare gains from efficient allocation of groundwater over space and time relative to the status quo policy of financial cost recovery in order to promote political feasibility an intertemporal compensation plan is devised that renders the reform pareto improving gainers from the reform finance the compensation in proportion to their benefits through a block pricing scheme for the honolulu case only 7 of the 441 million in gains to winners is needed to compensate losers from the reform future winners from the reform also repay the deficit created by the compensation package much as state and local governments finance capital improvements copyright 2009 oxford university press

the tax smoothing hypothesis evidence from sweden 1952 1999 this paper tests barro s 1979 tax smoothing hypothesis using swedish central government data for the period 1952 1999 according to the tax smoothing hypothesis the government sets the budget surplus equal to expected changes in government expenditure when expenditure is expected to increase the government runs a budget surplus and when expenditure is expected to fall the government runs a budget deficit the empirical evidence suggests that the model provides a useful benchmark and that tax smoothing behavior can explain about 60 percent of the variability in the swedish central government budget surplus
