fixing exchange rates a virtual quest for fundamentals abstract fixed exchange rates are less volatile than floating rates but the volatility of macroeconomic variables such as money and output does not change very much across exchange rate regimes this suggests that exchange rate models based only on macroeconomic fundamentals are unlikely to be very successful it also suggests that there is no clear tradeoff between reduced exchange rate volatility and macroeconomic stability

the effect of health savings accounts on group health insurance coverage this paper presents new empirical evidence on the impact of tax subsidies for health savings accounts hsas on group insurance coverage hsas are tax free health care expenditure savings accounts coupled with high deductible health insurance plans hdhps they together represent new health insurance options the tax advantage of hsas expands the group health insurance market by making health care more affordable using individual level data from the current population survey and exploiting policy variation by state and year from 2004 to 2012 i find that hsa tax subsidies increase small group coverage by a statistically significant 2 5 percentage points although not coverage in larger firms moreover if the tax price of hsa contribution decreases by 10 cents small group insurance coverage increases by almost 2 percentage points i also find that for older workers or less educated workers hsa subsidies are associated with 2 3 percentage point increase in their group insurance coverage

does right or left matter cabinets credibility and fiscal adjustments abstract this paper tests the widely held assumption that left wing cabinets favor higher public spending and examines whether cabinet ideology affects the persistence of major fiscal adjustments in a panel of large fiscal adjustments in oecd countries during the last 40 years we find evidence that left wing and right wing cabinets are partisan the left tends to reduce the deficit by raising tax revenues while the right relies mostly on spending cuts our testable hypothesis is that cabinets can signal commitment by undertaking fiscal adjustments in ways that are not favored by their constituencies in other words the left gains credibility when it cuts spending while the right becomes more credible when it increases tax revenues probit estimates of the determinants of persistence in fiscal adjustments confirm that spending cuts by the left and tax increases by the right are associated with persistent adjustments the effect is significant for cuts in public spending public consumption wage or nonwage increases in total revenues direct taxes on businesses and other taxes we test for the role of several other determinants of persistence confirming that coalition and majority cabinets are associated with less persistence while periods of high or rising levels of indebtedness favor persistence the estimates of the impact of ideology and other variables on gdp and its components show that it is the size of the spending cut rather than cabinet ideology that is most important

relative government size in globalization and its welfare implications as globalization spreads across the world countries are experiencing growing competitive pressure in many fields since the role of government is needed to change in this global era the so called government size debate has become fierce this article provides a measure of relative government size in globalization and clarifies the welfare effect of relative government size in globalization applying a simplified dynamic utility theoretical approach the main finding is that there is no systematic relationship between relative government size and relative welfare in globalization such relation depends on behavioural parameters such as the elasticity of inter temporal substitution of consumption and the disutility of labour this result suggests that finding prerequisites for government consumption to play a welfare improving role in globalization is more beneficial than the government size debate

real rigidities and the non neutrality of money rigidities in real prices are not sufficient to create rigidities in nominal prices and real effects of nominal shocks and by themselves small frictions in nominal adjustment such as costs of changing prices create only small non neutralities but this paper shows that substantial nominal rigidity can arise from a combination of real rigidities and small nominal frictions the paper shows the connection between real and nominal rigidity given the presence of nominal frictions both in general and for two specific sources of real rigidity one arising from goods market imperfections and the other from labour market imperfections

liquidity effects and the monetary transmission mechanism several recent papers provide strong empirical support for the view that an expansionary monetary policy disturbance generates a persistent decrease in interest rates and a persistent increase in output and employment existing quantitative general equilibrium models which allow for capital accumulation are inconsistent with this view there does exist a recently developed class of general equilibrium models which can rationalize the contemporaneous response of interest rates output and employment to a money supply shock however a key shortcoming of these models is that they cannot rationalize persistent liquidity effects this paper discusses the basic frictions and mechanisms underlying this new class of models and investigates one avenue for generating persistence we argue that once a simplified version of the model in christiano and eichenbaum 1991 is modified to allow for extremely small costs of adjusting sectoral flow of funds positive money shocks generate long lasting quantitatively significant liquidity effects as well as persistent increases in aggregate economic activity

the economics of worldwide stagflation the last fifteen years have witnessed dramatic changes in economics not only in the manner in which the economics profession views economics but also in the manner in which the general public views economics and economists by the late 1960 s there had emerged more or less a consensus macroeconomic framework that is an agreed upon structure to be used to study economic problems at the aggregate level robert solow stated as quoted in leijonhufvud 1968

an efficient employer strategy for dealing with adverse selection in multiple plan offerings an msa example this paper outlines a feasible employee premium contribution policy which would reduce the inefficiency associated with adverse selection when a limited coverage insurance policy is offered alongside a more generous policy the efficient premium contribution is defined and is shown to lead to an efficient allocation across plans of persons who differ by risk but it may also redistribute against higher risks a simulation of the additional option of a catastrophic health plan chp accompanied by a medical savings account msa is presented the efficiency gains from adding the msa catastrophic health insurance plan chp option are positive but small and the adverse consequences for high risks under an efficient employee premium are also small

the exchange rate and fiscal consolidation episodes in emerging market economies abstract an analysis of fiscal consolidations in emerging market economies during 1970 2004 suggests that exchange rate depreciation raises the probability of a fiscal consolidation being successful including when controlling for debt growth the composition of the consolidation and degree of democracy

exchange rates and prices the adjustment of relative prices to exchange rate movements is explained in an industrial organization approach given labor costs in the respective currencies exchange rate movements change costs for firms selling in the home market and thus disturb the industry equilibrium the extent of absolute and relative price adjustment is shown to depend on market integration product substitutability the relative number of domestic and foreign firms and the market structure the impact of exchange rates on prices is illustrated in a variety of approaches including the cournot a dixit and j stiglitz 1977 and s salop 1979 models some empirical evidence is offered in support of the theory copyright 1987 by american economic association

international evidence on tradables and nontradables inflation abstract using 1970 1985 sectoral data for the oecd we find that inflation in nontradable goods exceeds inflation in tradables we identify a demand shift towards nontradables and faster growth of total factor productivity in the tradable goods sector as the prime causes of the differential inflation in addition disinflation attempts and the exchange rate regime appear to have exerted significant influence on the relative inflation rate

tales of fiscal adjustment fiscal adjustments why they can be expansionary this paper examines the evidence on fiscal adjustments in oecd countries from the early 1960s to today the results shed light on the recently observed phenomenon of fiscal tightening that produces non keynesian expansionary effects one interpretation is that a serious fiscal tightening increases demand wealth rises when future tax burdens decline and when interest rates decline credibility is restored and inflation or default risks abate both consumption and investment rise for this effect to produce an expansion the tightening must be sizeable and occur after a period of stress when the budget is quickly deteriorating and public debt is building up another interpretation emphasizes the supply side typically a fiscal consolidation based on tax increases is short lived to be long lasting it must include cuts in public employment transfers and government wages to be politically possible such a policy must be supported by trade unions these measures result in more efficient labour markets and boost the supply side based both on statistical evidence and on a detailed analysis of ten cases of major fiscal adjustment this article provides cautious support to the supply side view without denying a more limited role for the demand side channel alberto alesina and silvia ardagna

separating the wheat from the chaff a disaggregate analysis of the effects of public spending in the us in this paper we undertake a systematic disaggregate analysis of the effects of government spending on economic activity in the us the level of disaggregation we consider is the highest available and is unprecedented in the empirical literature more specifically public consumption and public investment are decomposed into various subcategories which are measured at the levels of the federal defence and non defence and state and local governments for each subcategory we estimate a structural vector autoregression that identifies public spending shocks through the conditional heteroskedasticity of the structural disturbances thus relaxing the identifying restrictions commonly used in the literature our analysis reveals significant heterogeneity in the effects of public spending shocks on output both across subcategories and government levels shocks to spending on durables and structures are found to have the largest and most persistent effect on aggregate output with a peak multiplier that exceeds 1 our results also suggest that there is little association between the size of a given category of public expenditures and the magnitude of its effect on output resume separer le bon grain de l ivraie une analyse desagregee des effets des depenses publiques aux etats unis dans ce texte on entreprend une analyse desagregee des effets des depenses gouvernementales sur l activite economique aux etats unis le niveau de desagregation considere est le plus grand possible et est sans precedent dans la litterature empirique plus specifiquement la consommation et l investissement publics sont decomposes en diverses sous categories qui sont mesurees pour le gouvernement federal defense et non defense ainsi que pour les gouvernements des etats et locaux pour chaque sous categorie on estime un vecteur autoregressif structurel qui identifie les chocs de depenses publiques a travers l heteroscedastictite conditionnelle des perturbations structurelles pour ainsi rel cher les restrictions d identification communement utilisees dans la litterature l analyse revele une heterogeneite significative dans les effets des chocs de depenses publiques sur la production agregee selon les sous categories et les niveaux de gouvernement les chocs dans les depenses sur les biens durables et les structures tendent a avoir les effets les plus grands et les plus persistants sur la production agregee avec un effet multiplicateur qui excede 1 les resultats suggerent qu il y a peu de rapport entre la taille d une categorie donnee dans les depenses publiques et l ampleur de l effet sur la production agregee

short run independence of monetary policy under pegged exchange rates and effects of money on exchange rates and interest rates this paper examines the effects of money supply changes on exchange rates interest rates and production in an optimizing two country model in which some sectors of the economy have predetermined nominal prices in the short run and other sectors have flexible prices money supply shocks have liquidity effects both within and across countries and induce a cross country real interest differential the model predicts that liquidity effects are highly nonlinear and are not likely to be captured well empirically by linear models particularly those involving only a single country a striking implication of the model is that countries have a significant degree of short run independence of monetary policy even under pegged exchange rates copyright 1997 by ohio state university press

an examination of flexible spending accounts this paper develops a framework for analyzing flexible spending account fsa participation and usage we explore patterns of fsa usage using data from a benefits firm for 1996 including an examination of types of fsa expenditures and their timing we estimate some simple econometric models of the participation decision and also the decision of how much to put into an fsa several pieces of evidence suggest that much of an fsa election amount is based on foreknowledge of expenditures we also find that participants tend to spend their election amount early thus obtaining an interest free loan

medical savings accounts microsimulation results from a model with adverse selection this paper examines medical savings accounts combined with high deductible catastrophic health plans msa chps exploring the possible consequences of making tax preferred msa chps available to the entire employment related health insurance market the paper uses microsimulation methods to examine the equilibrium effects of msa chps on health care and non health care expenditures tax revenues insurance premiums and exposure to risk if msa chps are offered alongside comprehensive plans biased msa chp enrollment can lead to premium spirals that drive out comprehensive coverage our estimates also raise concerns about equity insofar as those who stand to lose the most tend to be poorer and in families with infant children

the new open economy macroeconomics of government debt in this paper we introduce an overlapping generations structure of the blanchard type in a new open economy macroeconomics model this allows us to study a wider range ofscal shocks compared to the traditional mundell fleming and to the baseline redux models one important policy implication of our model is that the tax cut imple mented in the us in 2001 might have contributed to the appreciation of the dollar vis a vis the euro in contrast the imposition ofscal constraint such as the golden rule proposed by the uk government can have opposite exchange rate e ects

much ado about two reconsidering retransformation and the two part model in health econometrics in health economics applications involving outcomes y and covariates x it is often the case that the central inferential problems of interest involve e y x and its associated partial effects or elasticities many such outcomes have two fundamental statistical properties y 0 and the outcome y 0 is observed with sufficient frequency that the zeros cannot be ignored econometrically this paper 1 describes circumstances where the standard two part model with homoskedastic retransformation will fail to provide consistent inferences about important policy parameters and 2 demonstrates some alternative approaches that are likely to prove helpful in applications

the welfare state and competitiveness in all industrial countries fiscal policy is increasingly about redistribution in this paper the authors study redistribution across different types of agents in a world characterized by the presence of labor unions and distortionary taxation they show that an increase in transfers financed by distortionary taxation has nonlinear effects on unit labor costs relative to the other countries depending on the degree of centralization of the wage setting process in the labor market the authors find considerable empirical support for the model in a sample of fourteen oecd countries copyright 1997 by american economic association

the impact of mortgage activity on recent demand deposit growth abstract this study quantifies the substantial effects of mortgage activity on recent demand deposit growth and finds that estimates and forecasts of recent demand deposit growth are considerably more accurate using data adjusted for mortgage activity

government spending and the real exchange rate i study the effect of government spending on the real exchange rate in an open economy version of the sidrauski model with a time varying rate of time preference that introduces complementarity between consumption at different points in time i show that a balanced budget fiscal expansion causes a real depreciation and a current account surplus if the expansion falls on traded goods if the increase falls instead on nontraded goods both the stylized results of a real appreciation and a current account deficit and the perverse result of an appreciation and a surplus can occur

health insurance and the demand for medical care evidence from a randomized experiment we estimate how cost sharing the portion of the bill the patient pays affects the demand for medical services the data come from a randomized experiment a catastrophic insurance plan reduces expenditures 31 percent relative to zero out of pocket price the price elasticity is approximately 0 2 we reject the hypothesis that less favorable coverage of outpatient services increases total expenditure for example by deterring preventive care or inducing hospitalization

liquidity loanable funds and real activity abstract this paper develops a general equilibrium model of two traditional explanations of the monetary black box linking money and real activity the liquidity effect and the loanable funds effect these effects are modeled with a monetary production economy in which central bank injections of cash are funnelled into the economy through the credit market since only borrowers have direct access to the newly injected cash monetary injections cause nominal interest rates to fall if firms are borrowers then monetary injections also increase current and future real activity

expenditure allocation across nondurables services durables and savings an empirical study of separability in the long run the separability of categories of consumption expenditures and savings are empirically examined in the context of an error correction model of aggregate quarterly expenditure allocations in canada some evidence is found for separability of consumption allocations from savings in both the long run structure and short run dynamics of the model lending some support to the use of the assumption in modelling consumption behaviour

the international ramifications of tax reforms supply side economics in a global economy this paper studies tax reforms in a dynamic model of a global economy calibrated to current u s and european tax policies world capital markets add consumption smoothing and income redistribution effects that alter closed economy predictions in the absence of taxes on foreign interest welfare gains of eliminating u s income taxes are enlarged by up to 34 percent at the expense of european losses caused by transitional declines in consumption and leisure and a permanent capital outflow in contrast if foreign interest is taxed the same tax reform reduces u s welfare 0 7 percent and increases european welfare 1 8 percent copyright 1998 by american economic association

the macroeconomic effects of monetary and fiscal policy in a small open economy does the exchange rate regime matter abstract this paper develops a small open economy model in the spirit of obstfeld and rogoff 1995 the introduction of endogenous traded sector output unlocks current account and real exchange rate effects within this framework where specific consideration is given to the case with fixed but adjustable parities exchange rate devaluation generates similar qualitative effects as a money supply expansion under floating rates output and external effects of government spending shocks are broadly consistent with the adjusted basic non micro founded mundell and fleming mf framework but differ in significant ways from the baseline mf model contrary to the textbook mf model a government expenditure shock depreciates the nominal exchange rate and generates real effects under the fixed rate system

a systemic approach to modelling and estimating demand for money ies this article uses a consumer theory based systemic approach to model the demand for monetary liquid asset holdings in chile we implement the suggestions and caveats of aggregation theory for the estimation of a demand system for liquid assets monies in static dynamic and time varying parameters setups our results are robust and theoretically consistent with consumer theory restrictions as a system derived from a utility maximizing framework and a quasi concave utility function in our estimations we find stability of interest rate elasticities in contrast to previous related literature we also document evidence that long short maturity rates are associated to less more liquid assets

the demand for divisia money in the united states a dynamic flexible demand system this paper applies the anderson and blundell 1982 approach to the analysis of the demand for money and attempts to establish the nature of the relationship between divisia money defined from narrow to broad and the nested like assets at different levels of aggregation this is achieved by conducting the analysis within a microtheoretical framework utilizing the demand system approach and by estimating a sequence of nested dynamic specifications and performing tests of the nested structures as well as on economic theory to establish the most restrictive dynamic specification acceptable to the data copyright 1991 by ohio state university press

size distortions of tests of the null hypothesis of stationarity evidence and implications for the ppp debate abstract tests of the null hypothesis of stationarity against the unit root alternative play an increasingly important role in empirical work in macroeconomics and in international finance we show that the use of conventional asymptotic critical values for stationarity tests may cause extreme size distortions if the model under the null hypothesis is highly persistent this fact calls into question the use of these tests in empirical work we illustrate the practical importance of this point for tests of long run purchasing power parity ppp under the recent float we show that the common practice of viewing tests of stationarity as complementary to tests of the unit root null will tend to result in contradictions and in spurious rejections of long run ppp while the size distortions may be overcome by the use of finite sample critical values the resulting tests tend to have low power under economically plausible assumptions about the half life of deviations from ppp thus the fact that stationarity is not rejected cannot be interpreted as convincing evidence in favor of mean reversion only in the rare case that stationarity is rejected do size corrected tests shed light on the question of long run ppp

impact of health savings accounts on precautionary savings demand for health insurance and prevention effort the paper examines the influence of health savings accounts hsas on optimal savings insurance demand and prevention effort over the course of a lifetime this paper adds to the literature by investigating hsas as both a form of insurance and as saving vehicle in an expected utility framework assuming no regulatory constraints on the deductible we show that individuals voluntarily choose a positive deductible and increase their savings with hsas if the government imposed minimum deductible becomes too great however individuals may instead choose to remain in traditional insurance we determine the effect of hsas on prevention effort we find that an increased tax subsidy may worsen moral hazard issues assuming partial risk aversion to be less than or equal to one individuals will either invest less in the health preservation effort and more money in the hsa or vice versa however they will never increase both effort and savings simultaneously as was intended when hsas were introduced

modeling u s households demands for liquid wealth in an era of financial change money demand models overpredicted m2 growth in the united states from 1990 to 1993 the authors examine this overprediction using a model of households demands for liquid wealth the model is a dynamic generalization of the aids model of angus deaton and john muellbauer 1980 the authors find that the own price elasticity of money rose substantially after 1990 they also find important cross price elasticities of money with respect to other liquid financial assets notably with respect to mutual funds incorporating these and other features helps explain nearly 50 percent of the shortfall in m2 growth over the period in question

fiscal policy profits and investment this paper evaluates the effects of fiscal policy on investment using a panel of oecd countries we find a sizeable negative effect of public spending and in particular of its wage component on profits and on business investment this result is consistent with different theoretical models in which government employment creates wage pressure for the private sector various types of taxes also have negative effects on profits but interestingly the effects of government spending on investment are larger than those of taxes our results can explain the so called non keynesian i e expansionary effects of fiscal adjustments jel e22 e62

trade spill overs of fiscal policy in the european union a panel analysis we explore the international spillovers from fiscal policy shocks via trade in europe a fiscal expansion stimulates domestic activity which leads to more foreign exports and hence higher foreign output to quantify this we combine a panel var model in government spending net taxes and gdp with a panel trade model on average a public spending increase equal to 1 of gdp implies 2 3 more foreign exports over the first two years the corresponding figure for an equal size net tax reduction is 0 6 both estimates are statistically significant as far as the effect on foreign activity is concerned a 1 of gdp spending increase net tax reduction in germany on average raises gdp of trading partners by 0 23 0 06 over the first two years these figures are likely to form lower bounds for the actual effects and suggest that it may be worthwhile to further investigate the benefits from coordinated fiscal expansions contractions in response to european wide cyclical downturns upswings

the importance of composition of fiscal policy evidence from different exchange rate regimes abstract we study the macroeconomic effects of fiscal policies in an open economy we emphasize two transmission mechanisms the cost channel by which wage government spending and labor taxes raise the real wage firms must pay and the exchange rate channel by which the nominal exchange rate shifts induced by fiscal policy have real effects if some prices and wages are sticky the latter channel implies that changes in wage government spending or in labor taxation should have different effects under flexible than under fixed exchange rates in a 1964 93 panel of oecd countries we find significant evidence for both channels moreover we find that the real product wage and profitability are more responsive than quantities employment and output to fiscal policy innovations

an empirical examination of information barriers to trade in insurance this paper uses direct evidence to evaluate whether asymmetric information is a barrier to trade in the largest market for private insurance in the world life insurance we report several findings that seem difficult to reconcile with the conventional theory of insurance under asymmetric information we conjecture that sellers may know their costs of production better than consumers in this market as in those for most other products

testing for homogeneity in demand systems when the regressors are nonstationary an implication of optimizing theory is that demand functions are homogeneous of degree zero in prices and nominal income evidence based on estimations of demand systems has repeatedly found this restriction to be rejected by the data however the hypothesis is often formulated in terms of regressors that are non stationary this paper re examines the evidence for homogeneity in light of recent developments in time series econometrics with special emphasis on the treatment of trends we find the demand system to be stochastically but not deterministically cointegrated using techniques developed for estimating cointegrating vectors in the presence of deterministic trends we re estimate the demand system and find that homogeneity holds in many cases

profitability and growth the link between profitability and growth is explored by means of an alternative explanation suggested by standard neoclassical theory of the firm the growth model developed clarifies the relationships between the real wage rate the rate of profit taxation and savings behavior and the rate of growth

understanding the dynamic effects of government spending on foreign trade abstract using vector autoregressions on u s time series the present paper documents the effects of fiscal policy on foreign trade an increase in government spending significantly depreciates the nominal exchange rate appreciates the terms of trade and increases net exports exposed to the same spending shock a new keynesian general equilibrium model is shown to match qualitatively the response of relative prices the response of net exports in contrast depends on the intra and intertemporal elasticities of substitution and the degree of home bias in private spending an accommodating monetary policy dampens but does not alter the response of net exports

the effects of government purchases shocks review and estimates for the eu in this article we review the theoretical consequences of government purchases shocks for both closed and open economies followed by a discussion of the empirical literature next we provide our own estimates for the eu countries we find that an increase in government purchases raises output consumption and investment and reduces the trade balance however the stimulating effect is weaker and the trade balance reduction is larger for the more open eu economies consistent with larger leakage effects further we show that government purchases shocks in large eu economies have non negligible consequences for economic activity in the main trading partners

competitive pooling rothschild stiglitz reconsidered we build a model of competitive pooling which incorporates adverse selection and signaling into general equilibrium pools are characterized by their quantity limits on contributions households signal their reliability by choosing which pool to join in equilibrium pools with lower quantity limits sell for a higher price even though each household s deliveries are the same at all pools the rothschild stiglitz model of insurance is included as a special case we show that by recasting their hybrid oligopolistic competitive story in our perfectly competitive framework their separating equilibrium always exists even when they say it does not and is unique

fiscal policy in good times and bad in the 1980s several countries with large government debt or deficit implemented substantial and in some cases drastic deficit cuts contrary to widespread expectations in many cases private consumption boomed rather than contracted this paper shows that in times of fiscal stress shocks to government revenues and especially expenditure have very different effects on private consumption than in normal times

insurance choice and tax preferred health savings accounts we develop an infinite horizon utility maximization model of the interaction between insurance choice and tax preferred health savings accounts the model can be used to examine a wide range of policy options including flexible spending accounts health savings accounts and health reimbursement accounts we also develop a 2 period model to simulate various implications of the model key results from the simulation analysis include the following 1 with no adverse selection use of unrestricted health savings accounts leads to modest welfare gains after accounting for the tax revenue loss 2 with adverse selection and an initial pooling equilibrium comprised of sick and healthy consumers introducing hsas can but does not necessarily lead to a new pooling equilibrium the new equilibrium results in a higher coinsurance rate an increase in expected utility for healthy consumers and a decrease in expected utility for sick consumers 3 with adverse selection and a separating equilibrium both sick and healthy consumers are better off with a health savings account 4 efficiency gains are possible when insurance contracts are explicitly linked to tax preferred health savings accounts

obstacles to disinflation what is the role of fiscal expectations persistently high expected inflation often makes it difficult for policy makers to recover from inflationary episodes without substantial output losses using survey data from eleven disinflation episodes we can assess whether the more or less sluggish decline of inflation rates towards lower target levels is related to backward looking pricing behavior or to imperfect credibility of the stabilization efforts we find that expectations of future inflation play a much more important role than past inflation in shaping the inflation process second we find that an improvement in various measures of fiscal balances significantly reduces inflation expectations this evidence suggests that when attempting to stabilize inflation priority should be given to building fiscal credibility oya celasun r gaston gelos and alessandro prati

competitiveness through disinflation an assessment of the french macroeconomic strategy france olivier jean blanchard and pierre alain muet over most of the last decade france has followed increasingly rigorous policies the hard franc approach has meant that external competitiveness is no longer sought through devaluation instead the new policy is to achieve a lower inflation rate than abroad in principle the competitiveness through disinflation approach should work and eventually bring down the unemployment rate which has remained broadly unchanged at a high level for many years while maintaining external balance this article investigates whether the policy is working inflation is lower than in germany profits have steadily increased and trade balance has been reestablished but unemployment is higher than in 1983 the policy has been more successful at bringing down inflation than at returning the economy to lower unemployment the adjustment process has been protracted credibility effects have not been fulfilled but nor however have fears that the drastic change of policy might prove unusually disruptive it simply turns out that the policy is working very slowly it would take an improbable 30 accumulated competitiveness gain to bring unemployment down by 3 which does not seem acceptable to france s trading partners

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

foreign labor costs and domestic employment what are the spillovers abstract this paper studies the international spillover effects of country specific labor cost changes in the presence of labor market frictions a two country model with search frictions predicts that a cut in foreign labor costs leads to an increase in domestic employment driven by a positive terms of trade effect on job creation i find empirical evidence in support of this positive spillover effect the terms of trade channel and the dependence on the degree of labor market rigidity this is done by a panel regression that estimates the effect of exogenous variation in foreign unit labor costs instrumented by changes in foreign statutory social security contribution rates on domestic employment and output

trigger points and budget cuts explaining the effects of fiscal austerity we propose and solve an optimizing model which explains counterintuitive effects of fiscal policy in terms of expectations if government spending follows an upward trending stochastic process which the public believes may fall sharply when it reaches specific trigger points then optimizing consumption behavior and simple budget constraint arithmetic imply a nonlinear relationship between private consumption and government spending this theoretical relation is consistent with the experience of several countries jel e62 e21 textbook aggregate demand models suggest simple relationships between the government budget and economic activity a cut in the government deficit for example depressing consumption and output though such models heavily influence the design of stabilization policies their micro foundations are unclear and their sharp predictions are not always consistent with reality in many countries large cuts in government spending carried out as part of stabilization programs have led to expansions rather than contractions in economic activity the absence of simple relationships be

divergent inflation rates in emu inflation divergence inflation rates have diverged much more widely than expected among the member states of the emu we show that much of this is attributable to the differential impact on different member states of the weakness of the euro on international currency markets in the early months of the union the balassa samuelson productivity growth effect has not yet played an important role even in respect of the outlier ireland although it will likely be more significant over a longer run especially as the accession countries join patrick honohan and philip lane
