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

sustainability of current account deficits in india an intertemporal perspective this study examines the sustainability of current account deficits cads and the validity of intertemporal budget constraint ibc in india the long run model is estimated on annual data for the period 1950 1951 to 2009 2010 the optimal single equation and maximum likelihood ml system estimates of the model provide a consistent support for the long run relationship between imports and exports the olsgh estimates provide no support and that ml system estimates a consistent support for cointegration in both the models estimated with one and two structural breaks in level the new cointegration breakdown tests generally suggest that the cointegration prevails from 1951 to 2010 the evidence supporting the cointegration between imports and exports overwhelms the evidence providing a mixed or no support for cointegration the estimates of slope parameter above zero and the dominant support for cointegration between imports and exports vindicate the validity of ibc and the sustainability of cads the shor

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

some stabilizing and destabilizing effects of foreign debt accumulation in developing countries abstract recent research indicates that current account imbalances in the three largest industrial countries germany japan and the united states are self correcting a long run equilibrium relationship exists between the cumulated current account which is the net stock of these countries foreign assets or liabilities and other economic factors the situation appears to be different in a sample of 26 developing countries examined here this paper attempts to explain why it examines the effects on the current account of government and government guaranteed foreign debt on the one hand and net foreign liabilities or the cumulated current account deficit on the other while the cumulated current account deficit does generate stabilizing forces possibly through wealth effects large amounts of government and government guaranteed debt create destabilizing effects by stimulating capital flight

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

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

fiscal policy and the current account deficits and trade jose vinals does the balance of payments act as an external constraint on the design of domestic economic policy in practice most governments believe it does yet popular discussion is sometimes confused this paper begins by evaluating the nature of the external constraint and the extent to which it can adequately be measured by the current account of the balance of payments it is often argued that a fiscal expansion will increase employment it is also widely held that a fiscal expansion necessarily leads to a deterioration of the current account while these propositions may hold in specific circumstances neither is generally true the theoretical basis of the two propositions is examined and compared with recent international experience when important changes in fiscal stance occurred the popular presumptions are confirmed by recent experience in the us the uk and germany but france is a counterexample to the first and spain to the second the important policy implication is that one can identify both in theory and in practice clear circumstances in which expansionary fiscal policy is appropriate and will not be thwarted by external considerations

international intertemporal solvency in industrialized countries evidence and implications recent large current account deficits among industrialized countries have caused concern for policy makers some believe for example that the current buildup of claims on the u s by foreigners violates her solvency condition with respect to the rest of the world recent research 22 suggests that for a country s intertemporal solvency condition to hold the change in the country s obligations to the rest of the world i e her current account deficit must be stationary stationarity tests on current accounts were performed for the u s by trehan and walsh 22 and wickens and uctum 23 for the u s and canada by otto 15 and for twenty three countries by gundlach and sinn 10 these papers present evidence that current accounts are non stationary for several major industrialized countries including the u s the u k canada germany and japan these findings do not favor international intertemporal solvency for this reason the issue merits further investigation in this paper we test for the stationarity of current account deficits of the group of seven industrialized countries preliminary results confirm many of gundlach and sinn s 10 findings however several events during the 1980s might have caused discrete breaks in current account balances events potentially linked with current account breaks include the reduction in world inflation tax reduction and reform in the u s and other industrialized countries attempts at international macroeconomic coordination i e the plaza accord and shifts in the after tax rate of return on capital in many countries as shown in recent research on gross national product 16 2 if such breaks are not accounted for stationarity tests will be biased in favor of accepting the null hypothesis of non stationarity our results suggest strong evidence of discrete breaks in the u s and japan and some evidence favoring breaks in the u k germany and canada the break in the u s current account appears to occur in 1983 while breaks in the other countries appear to occur somewhat later between late 1984 and 1987 more importantly once these breaks are incorporated the evidence is more favorable toward the stationarity of current accounts in these countries these findings thus support intertemporal solvency for these countries

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

financial distress drivers in brazilian banks a dynamic slacks approach abstract this study applies the dynamic slacks based model dsbm developed by tone and tsutsui 2010 in order to assess the evolution of input saving output increasing potentials in major brazilian banks from 1996 to 2011 we propose that these potentials or slacks can be used as proxies for an eventual financial distress situation in the future the main research objective is to determine whether or not different characteristics of bank type related to ownership size and merger and acquisition processes are significantly related to inefficiency levels and by extension to an eventual financial distress situation since higher inefficiency levels also imply lower input saving output decreasing potentials based on a balanced panel model secondary data from economatica were collected and analyzed results indicate higher inefficiency levels and slacks in small public and national banks policy implications are also addressed

a century of current account dynamics abstract recent globalization trends have refocused attention on the historical evolution of international capital mobility over the long run the issue is examined here using time series analysis of current account dynamics for fifteen countries since circa 1850 the inter war period emerges as an era of low capital mobility and only recently can we observe a tentative return to the degree of capital mobility witnessed during the late nineteenth century the analysis of saving and investment dynamics also helps make sense of the frequently observed high correlation of saving and investment rates in historical data

the sustainability of current account deficits abstract this paper proposes a new method of determining whether a country is likely to be able to sustain its current account deficits without defaulting on its debt it is based on the notion of the national intertemporal budget constraint ibc which is derived from a forward solution of the balance payments identity although the problem is formally similar to that considered in the literature on the government ibc a more general solution is obtained by allowing the primary deficit to be endogenous instead of exogenous it is shown that the existence of negative feedback from net indebtedness to the primary deficit a wealth effect is sufficient this method supplants the ad hoc approach previously adopted in the current account literature whilst many of the same variables appear a formal structure for analysing them is provided

international trends in technological progress evidence from patent citations 1980 2011 we analyse cross country trends in several aspects of technological progress during 1980 2011 by examining the us patent citations data our estimation results on patent quality and citation lags relative to the us reveal the following the emerging asian economies of korea taiwan and china have achieved substantial catch up in the case of korea and taiwan progress has been made in both patent quality and citation lags china has achieved improvement in patent quality but not in citation lag in contrast advanced economies of europe and japan have displayed steady decline in patent quality while the us has strengthened its position

business cycles in international historical perspective business cycle models seek to answer the question of why economies go through cycles of recession and recovery or boom and bust any theory of the business cycle makes two sorts of claims what shocks are most important in disturbing the economy and what economic structure is necessary for propagating these shocks for example one common explanation of business cycles begins with monetary shocks and then seeks to explain why monetary shocks are not purely neutral as neoclassical theory would have it and instead have real effects at least in the short term early models in this vein were often implicitly or explicitly based on the proposition that markets do not clear continuously early equilibrium real business cycle theories instead emphasized the importance of real shocks especially to technology which may cause socially efficient fluctuations even when markets are always in equilibrium more recent models have attempted to marry the equilibrium approach to macroeconomics with the substantive keynesian ideas that money is not neutral and that economic fluctuations are costly new keynesian theories of the business cycle admit the possibility of a number of economic shocks including monetary and technology shocks but then focus on explaining how nominal price rigidities within the economy can turn these shocks into recessions or booms other models show that business cycles driven by keynesian animal spirits are consistent with rigorous microfoundations and rational expectations seeking empirical evidence for and against these various approaches we turn business cycle theories loose on perhaps the greatest macroeconomic laboratory

how to evaluate the solvency of an indebted nation reassessing third world debt daniel cohen the conventional measures of the solvency of developing countries usually rely on such indices as debt export or debt gnp ratios the underlying rationale is that to be solvent a country must eventually pay back all its debt this paper starts from two simple but important remarks first solvency need not require the full eventual repayment of all debt continued borrowing may be possible rather what is required is that a country s debt accumulation does not outstrip its capacity to make future repayments and the capacity of lenders to make future loans second solvency therefore cannot be defined independently of the growth rates of lender and borrower countries nor of the interest rate at which past debts accumulate putting these ideas together a new solvency index is proposed and this is computed for all the less developed countries this new index suggests a less gloomy view of the international debt crisis the largest debtors may have already accomplished an adjustment which is more than sufficient to restore their solvency when this is properly computed to investigate this claim there is a detailed analysis of the policies recently adopted in argentina and brazil

assessing the fiscal stance in the european union and the united states 1970 2011 the huge increases in debt gdp ratios following the 2007 2009 global financial crisis which are unprecedented except in times of war has focused attention on the viability of the fiscal positions of eu countries and the us how to assess this and the likely future evolution of these positions this paper proposes an indicator of the fiscal stance which computes the fiscal adjustment required to reach a specific debt gdp targeted given the forecasts of future deficit and interest rates obtained from an unrestricted recursively estimated var model the index is easy to compute and can be decomposed to disclose the different contribution of revenue expenditure nominal yields inflation and growth to the fiscal stance for this reason it provides a transparent and detailed measure of the fiscal stance particularly suitable for multi country surveillance as a result the index improves on the tax gap indicators widely used by governments and international agencies and is far more informative than formal econometric tests of fiscal sustainability the time series of the indicator for individual eu countries and the us show that their fiscal position has fluctuated considerably over the last 40 years and has particularly deteriorated since 2007 the index predicts that the adjustment required to restore pre crisis debt gdp levels are higher for high debt countries like greece italy and portugal they become more severe the shorter is the time horizon for the adjustment as a large degree of uncertainty surrounds the assessment of the fiscal stance in the medium and long run we argue that policy makers should inform their policy based on the worst case scenario predicted by the indicator

public debt the unit root hypothesis and structural breaks a multi country analysis we assess fiscal performances in g7 and selected latin american and asian countries we consider two questions i have public finances been sustainable ii do countries follow more restrictive fiscal policies when debt starts to rise we find that i the traditional unit root tests often overlook the corrective actions taken by many governments controlling for structural breaks changes the non stationarity results dramatically among the three groups ii estimation of a reaction function for governments expanded by incorporating structural breaks provides further evidence for significant active anti debt policies among g7 countries and to a lesser extent in the other regions

current account deficit sustainability the case of barbados this article investigates the sustainability of the current account deficit in barbados over the period 1960 to 2006 various unit root and cointegration techniques are employed to determine whether the country is satisfying its intertemporal budget constraint ibc the cointegration regressions suggest that the current account of barbados is sustainable and that deviations from long run equilibrium between real exports and imports are corrected in the short run with imports making the adjustment

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

fiscal reaction under endogenous structural changes in brazil abstract regarding the importance of fiscal policy in smoothing the impact of shocks such as the international financial and economic crises the paper analyzes the sustainability of the brazilian fiscal policy by taking into consideration the possibility of multiple endogenous structural breaks on the coefficients of government reaction function from monthly data in the period 1991 2008 tests on the reliable estimates dictate the occurrence of structural change in may 1994 and another in february 2003 there has been a situation of fiscal solvency in brazil but only from may 1994 the hitherto innocuous actions of government to formulate policies on public debt turn out to be significant as it rose twofold after february 2003 this reinforces the existence of a more flexible alternative to implement strategic policy in brazil if an eventual alternative for increasing public spending is a way of hindering the effects of international financial crises without compromising the fiscal targets

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

u s federal indebtedness and the conduct of fiscal policy abstract this paper examines whether the conduct of u s fiscal policy since the 1920s has been influenced by constraints on the accumulated stock of outstanding federal debt the evidence is affirmative during most of the inter and post war period policy in effect stabilized the federal debt relative to gnp but after 1981 large debt and debt service costs failed to produce deficit reductions consistent with the pattern of previous decades

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

foreign debt accumulation financial and fiscal effects and monetary policy reactions in developing countries abstract this paper analyzes the effects of the current account of government and government guaranteed foreign debt on the one hand and net foreign liabilities or the cumulated current account deficit on the other hand in a sample of 26 developing countries while the cumulated current account deficit generates stabilizing forces pissibly through financial and wealth effects large amounts of government and government guaranteed debt produce destabilizing effects by stimulating capital flight i also find that monetary policy reactions are stabilizing in the case of the cumulated current account deficit but desstabilizing in the case of a build up of government and government guaranteed foreign debt jel f32 f34

on the solvency of nations cross country evidence on the dynamics of external adjustment we test the hypothesis that net foreign asset positions are consistent with external solvency and examine the dynamics of external adjustment using data for 50 countries over the 1970 2006 period our analysis adapts bohn s 2007 error correction reaction function approach which tests for a negative long run relationship between net exports nx and net foreign assets nfa as a sufficiency condition for the intertemporal budget constraint to hold to a dynamic panel framework pooled mean group pmg and mean group error correction estimation yield evidence of a statistically significant negative response of nx to nfa moreover we cannot reject the hypothesis that the response is largely homogeneous across countries our sensitivity analysis shows that the countries with relatively weaker fundamentals need to respond more strongly to the changes in nfa to keep their nfas on a sustainable path

the sustainability of india s current account this study conducts an investigation into the sustainability of the indian current account using data for 1950 onwards a necessary condition for current account sustainability is that exports and imports are cointegrated after testing for unit roots that allow for a structural break we employ parametric tests for cointegration based on johansen 1995 and saikkonen and lutkepohl 2000a b c as well as the nonparametric procedure proposed by breitung 2002 and breitung and taylor 2003 that does not assume linearity by employing these procedures recursively two distinct regimes are identified characterized by whether or not imports and exports are cointegrated the regime of noncointegration runs until the late 1990s and the second regime of cointegration is present after that this latter regime coincides with the liberalization of the indian economy
