the sustainability of south african fiscal policy an historical perspective this article examines the issue of long run fiscal sustainability in south africa by applying a battery of recently developed unit root and cointegration tests to real revenue and spending data for the period 1895 to 2005 the results provide evidence that allowing for structural breaks south african revenue and spending during this period were i 1 series and cointegrated with the estimated long run equilibrium relation supporting the presence of a weak deficit sustainability condition the views expressed in this article are those of the authors and should not be attributed to the international monetary fund

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 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

institutional work and climate change corporate political action in the swedish electricity industry this paper utilises qualitative methods to examine factors that influence corporate political actions cpa linked to climate policy in the swedish electricity industry cpa strategies are examined in connection to two policy instruments the eu emission trading scheme and the swedish electricity certificate scheme these instruments are the main drivers of climate related investments in the sector the study treats cpa as a form of institutional work and examines reasons for companies to seek to maintain disrupt institutions the study finds that cpa is driven primarily by the need to manage external resource dependencies and that where risks are more acute companies are more likely to seek to disrupt regulative institutions however the study also shows that respondents appraisals of policy instruments are based on a convergent set of shared values cognitive institutions that form the basis of cpa and which actors do not seek to disrupt despite resource based risks cpa is thus characterised as a means to transmute cognitively held values and beliefs into regulative institutions the study concludes with implications for policymakers and theory

money market pressure and the determinants of banking crises this article develops an index of money market pressure to identify banking crises we define banking crises as periods in which there is excessive demand for liquidity in the money market we begin with the theoretical foundation of this new method with the newly defined crisis episodes we examine the determinants of banking crises using data complied from 47 countries we find that slowdown of real gdp lower real interest rates extremely high inflation large fiscal deficits and over valued exchange rates tend to precede banking crises the effects of monetary base growth on the probability of banking crises are negligible

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

unit roots structural breaks and cointegration in the uk public finances 1750 2004 in this article we report results from several traditional and more recently developed unit root and cointegration tests allowing for structural breaks which indicate that uk government revenue and spending during 1750 2004 were i 1 series and cointegrated and that the uk public finances have been on a consistently sustainable path over the long run

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 interbank market during a crisis abstract the autumn of 1998 provides a setting in which to test the performance of the interbank market during a potential financial crisis this period witnessed russia s effective default on its sovereign bonds and the near collapse of the hedge fund long term capital management despite these negative shocks to bank capital and increased uncertainty in financial markets the federal funds market still effectively channeled liquidity to those institutions in need at rates consistent with federal reserve intentions further risk premiums on overnight lending were largely unaffected and lending volumes increased suggesting that the federal funds market performed well during this period

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

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

does deposit insurance increase banking system stability an empirical investigation based on evidence of 61 countries in 1980 97 the authors find that explicit deposit insurance tends to be detrimental to bank stability the more so where bank interest rates are deregulated and the institutional environment is weak the adverse impact of deposit insurance on bank stability tends to be stronger the more extensive is the coverage offered to depositors and where the scheme is funded and run by the government rather than the private sector

early warning systems and systemic banking crises in low income countries a multinomial logit approach abstract this paper estimates an early warning system ews for predicting systemic banking crises in a sample of low income countries in sub saharan africa since the average duration of crises in this sample of countries is longer than one year the predictive performance of standard binomial logit models is likely to be hampered by the so called crisis duration bias the bias arises from the decision to either treat crisis years after the onset of a crisis as non crisis years or remove them altogether from the model to overcome this potential drawback we propose a multinomial logit approach which is shown to improve the predictive power of our ews compared to the binomial logit model our results suggest that crisis events in low income countries are associated with low economic growth drying up of banking system liquidity and widening of foreign exchange net open positions

macroeconomic adjustment and the history of crises in open economies abstract this paper investigates the impact of the history of crises on macroeconomic performance we first study the impact of past banking crises on the probability of a future banking crisis we do not detect a learning process from past banking crises countries that have already experienced one banking crisis generally have a higher likelihood of experiencing another crisis and the depth of the crisis does not appear to be affected by the previous historical experience with crisis events evidence also suggests that in middle income countries higher de jure capital account openness is associated with lower likelihood of a banking crisis a lower ratio of non performing loans during the crisis and higher levels of forgone output in the crisis aftermath in contrast we find that past crisis experience has a significant impact on savings when facing considerable political risk the past does seem to matter countries with more people who were exposed over their lifetime to larger disasters will tend to save more this association however does not hold for countries with more stable political systems

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

forecasting the fragility of the banking and insurance sectors linkages between banks and insurance companies are important when forecasting the fragility of the banking and insurance sectors we propose a novel empirical framework that allows us to estimate unobserved linkages in panel data sets that contain observed regressors we find that taking unobserved common factors into account reduces the root mean square forecasts error of firm specific forecasts by up to 9 of system forecasts by up to 14 and by up to 39 for systemic forecasts of more distressed firms relative to a model based on observed variables only estimates of the factor loadings suggest that the correlation of financial institutions has been relatively stable over the forecast period

testing for the government s intertemporal budget restriction in brazil during 1823 1889 this article tests whether the government s intertemporal budget restriction was fulfilled during the brazilian imperial period 1823 1889 to accomplish this newly developed tests for cointegration with unknown structural breaks are applied it is found that government spending and government revenue are cointegrated if the effect of two unknown structural breaks is taken into account the estimated parameter vector reveals that the one by one relationship that is required for solvency does not prevail for the sub periods before and after the first break however it prevails for the sub period after the second break we interpret these findings as empirical support for the long run government solvency in brazil at the end of the imperial period

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

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

together or apart the relationship between currency and banking crises abstract the purpose of this study is to provide empirical evidence on the links between currency and banking crises panel data probit and bivariate probit models are estimated to a sample of 21 developed and developing countries having monthly observations between the years 1985 and 2010 the findings indicate that banking crises precede currency crises and vice versa currency crises also indirectly influence future banking crises probability through external shocks liberalized financial markets or highly leveraged banking sectors the study also finds evidence of contemporaneous correlation between the two crises the results not only confirm the theoretical links between banking and currency crises but also underline the importance of higher frequency data in analyzing the relationship between various financial crises

car ownership and use in britain a comparison of the empirical results of alternative cointegration estimation methods and forecasts this paper addresses two problems faced by many forecasters in the transport sector namely how to use a relatively small sample to forecast car ownership over a long period of time and avoid the difficulties caused by spurious or nonsense regressions five alternative estimation methods are used to test for cointegrating relationships between per capita car ownership and use and real per capita personable disposable income real motoring costs and real bus fares these are the engle granger two stage the phillips hansen fully modified the wickens breusch one stage the autoregressive distributed lag and the johansen maximum likelihood methods the corresponding error correction models are estimated and a comparison made between the derived short and long run demand elasticities for car ownership and use the ex post forecasting performance of the error correction models together with an arima model specification is evaluated using a number of performance criteria the long range time series fore

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

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

nonlinearities and the sustainability of the government s intertemporal budget constraint i introduction fiscal policy sustainability is an important issue for european union eu countries which are subject to some forms of monitoring of their public finances the european stability and growth pact esgp constrains the fiscal policy of member states by limiting their autonomy in creating excessive deficits 1 this because fiscal disequilibria in one state create negative externalities for the other member countries and in the case of european monetary union emu countries can endanger the overall credibility of the euro currency on the other hand given the common monetary policy the correction of idiosyncratic shocks is assigned to the fiscal instrument alone imposing further pressure on the fiscal policy of member countries while the issue of sustainability of the public finances of the eu emu countries has received an increasing attention less attention has been paid to the issue of how the sustainability is achieved that is how budgetary authorities adjust fiscal policies to achieve maintain a sustainable path of public debt focusing on this adjustment by applying linear and nonlinear error correction models is the main purpose of this paper our empirical analysis is based on italy which provides an interesting case as it joined the emu in 1999 in spite of a stock of public debt of around 113 of nominal gdp against the 60 level required by the maastricht treaty and whose public accounts are often under scrutiny for struggling to comply with the esgp 2 as well as for subsequent downgradings of its sovereign debt by the main credit rating agencies 3 in this paper we address three main relevant policy questions first are the italian public finances sustainable second is the process of fiscal adjustment equally shared by changes in revenues and changes in government spending third does fiscal adjustment vary with the sign and magnitude of disequilibria and or with the state of the economy these are important questions for policy making purposes although our methodology is only applied to italy we feel our work should be of definite interest to other european countries and beyond bearing in mind that italy enjoys membership of the g7 economies and accounts for around 17 of eurozone s gdp a better understanding of how its public finances operate in practice is extremely important for monitoring the fiscal health of eurozone countries and minimizing at an early stage possible threats to eurozone s stability as well as limiting any spill over effects to the rest of the world further loans from the european financial stability facility 4 efsf can only meet the approval of policymakers if they feel confident they have a deep understanding of how individual member states pursue their own fiscal policies toward sustainability verifiability and credibility of sustainable fiscal policies would also condition the availability of the european stability mechanism consisting in a permanent bail out fund for eurozone member states bofinger et al 2010 that is expected to become operational from 2013 at the expiry of the efsf at the same time proposals for independent monitoring of public finances of member states as well as stricter sanctions such as the temporary suspension of voting rights for eurozone members that break the region s rules on public finances are put forward by the european central bank trichet 2010 all these recent policy developments confirm the importance of our research in providing a comprehensive framework for empirically testing the sustainability of fiscal policy our proposed approach provides a number of interesting findings the italian government s intertemporal budget constraint ibc is formally respected in spite of the high levels of public debt nevertheless the burden of correcting budgetary disequilibria is entirely carried out via changes in the average tax rate rather than changes in government spending or policy mixes

exchange market mayhem the antecedents and aftermath of speculative attacks exchange market mayhem the antecedents and aftermath of speculative attacks this paper evaluates the causes and consequences of episodes of turbulence in foreign exchange markets using data from 1959 through 1993 for twenty oecd countries we consider the antecedents and aftermath of devaluations and revaluations flotations fixings and speculative attacks which may not be successful we find that realignments of fixed exchange rates are alike devaluations are preceded by political instability budget and current account deficits and fast growth of money and prices revaluations are mirror images of devaluations speculative attacks resemble devaluations but money growth and inflation are more endemic and there is no last minute attempt to tighten monetary policy in contrast few consistent correlations link regime transitions like flotations or fixings to macroeconomic or political variables transitions between exchange rate regimes are largely idiosyncratic and are neither consistently provoked ex ante by systematic imbalances nor typically justified ex post by subsequent changes in policy we conclude that there are no clear early warning signals of many speculative attacks and no easy solutions for policy makers barry eichengreen andrew k rose and charles wyplosz

financial crises payment system problems and discount window lending in a developed economy financial crises are rapidly conveyed to the payment system which tends to rely on private credit extensions in most countries while many authors recommend that the central bank do no more than provide adequate aggregate liquidity during a crisis this policy requires well functioning private credit markets to channel liquidity to solvent but illiquid firms this paper presents a model of private lending which defines a crisis as a time when lenders become uncertain about how to assess financial risks and therefore rationally withdraw from making new loans in such an environment a government lender of last resort can improve social welfare copyright 1996 by ohio state university press

turkish budget deficit sustainability and the revenue expenditure nexus the sustainability of the turkish budget deficits as well as the dynamics of government revenues and expenditures in controlling the size of the deficit is examined using annual data from 1968 to 2004 the findings support the existence of a long run relation between government revenues and expenditures once allowance is made for an unknown structural break however the size of the slope parameter is significantly less than one suggesting that the government might face difficulties in financing its future debt with respect to the revenue expenditure nexus the empirical evidence is favourable to the tax spend hypothesis through the error correction term in the expenditures equation finally there is no evidence of asymmetries in the adjustment process in either the threshhold autoregressive or momentum threshold autoregressive specifications of the budgetary adjustment process
