the macroeconomics of fiscal consolidations in euro area countries we simulate a currency union dynamic general equilibrium model to assess the macroeconomic implications of permanently reducing the public debt to gross domestic product gdp ratio in euro area countries we obtain the following results first tax distortions are quantitatively significant second the best fiscal consolidation strategy is to permanently reduce both expenditures and tax rates third under such a consolidation strategy the transition is generally not costly as the gdp and investment would grow while private consumption would not fall finally spillovers to the rest of the euro area are generally expansionary

hidden underemployment among irish farm holders 2002 2011 this article examines the scale of hidden underemployment on irish farms from 2002 to 2011 we provide a measure of hidden underemployment that is not captured by the national level statistics hidden underemployment can be attributed to a number of factors relating to inadequate employment situations as described at the 16th international conference of labour statisticians such as low productivity the poor utilization of skills and other factors specific to agriculture we place particular attention upon the potential role of off farm labour supply in solving the underemployment problem we utilize a two stage residual inclusion model and a random effects probit model to examine the forces behind farm underemployment we utilize a fixed effects model to examine the factors driving the severity of farm underemployment our findings suggest that instances of hidden underemployment increased between 2002 and 2011 hidden underemployment appears to be a stubborn problem and is related to the absence of off

optimal fiscal feedback on debt in an economy with nominal rigidities we examine the impact of different degrees of fiscal feedback on debt in an economy with nominal rigidities where monetary policy is optimal we look at the extent to which different degrees of fiscal feedback enhances or detracts from the ability of the monetary authorities to stabilise output and inflation using an objective function derived from utility we find the optimal level of fiscal feedback to be small there is a clear discontinuity in the behaviour of monetary policy and welfare either side of this optimal level as the extent of fiscal feedback increases optimal monetary policy becomes less active because fiscal feedback tends to deflate inflationary shocks however this fiscal stabilisation is less efficient than monetary policy and so welfare declines in contrast if fiscal feedback falls below some critical value either the model becomes indeterminate or optimal monetary policy becomes strongly passive and this passive monetary policy leads to a sharp deterioration in welfare

the taylor principle fights back part ii abstract the existing literature holds that the taylor principle often leads to indeterminacy in new keynesian models that allow for capital accumulation and limited asset market participation this conclusion is special however to the case of continuous full employment when the assumption of perfect wage flexibility is relaxed very slightly so that the labor market clears quickly but not instantaneously determinacy is the norm the threat of indeterminacy is limited to a tiny irrelevant corner of the parameter space where the elasticity of labor supply is unusually high and real wage adjustment is unbelievably fast everywhere else the taylor principle guarantees a unique rational expectations equilibrium the dramatic difference in results reflects the sensitivity of the monetary transmission mechanism to the speed of adjustment in the labor market

short term gdp forecasting with a mixed frequency dynamic factor model with stochastic volatility in this article we develop a mixed frequency dynamic factor model in which the disturbances of both the latent common factor and of the idiosyncratic components have time varying stochastic volatilities we use the model to investigate business cycle dynamics in the euro area and present three sets of empirical results first we evaluate the impact of macroeconomic releases on point and density forecast accuracy and on the width of forecast intervals second we show how our setup allows to make a probabilistic assessment of the contribution of releases to forecast revisions third we examine point and density out of sample forecast accuracy we find that introducing stochastic volatility in the model contributes to an improvement in both point and density forecast accuracy supplementary materials for this article are available online

vector autoregressions and reduced form representations of dsge models abstract the performance of dynamic stochastic general equilibrium models is often tested against estimated vars this requires that the data generating process consistent with the dsge theoretical model has a finite order var representation this paper discusses the assumptions needed for a finite order var p representation of a dsge model to exist when a var p is only an approximation to the exact infinite order var the truncated var p may return largely incorrect estimates of the impulse response function the results do not hinge on small sample bias or on incorrect identification assumptions but the bias introduced by truncation can lead to bias in the identification of the structural shocks identification strategies that work in the exact var representation perform poorly in the truncated var

estimating fiscal limits the case of greece summary this paper uses bayesian methods to estimate a real business cycle model that allows for interactions among fiscal policy instruments the stochastic fiscal limit and sovereign default using the particle filter to perform likelihood based inference we estimate the full nonlinear model with post emu data until 2010 q4 we find that i the probability of default on greek debt was in the range of 5 10 in 2010 q4 and ii the 2011 surge in the greek real interest rate is within model forecast bands the results suggest that a nonlinear rational expectations environment can account for the greek interest rate path copyright 2014 john wiley sons ltd

great recession slow recovery and muted fiscal policies in the us this paper reconsiders the role of macroeconomic shocks and policies in determining the great recession and the subsequent recovery in the us the great recession was mainly caused by a large demand shock and by the zlb on the interest rate policy in contrast with previous findings the subsequent jobless recovery is explained by the zlb effect we estimate a fraction of non ricardian households which is close to 50 and obtain comparatively large fiscal multipliers however we cannot detect a significant contribution of fiscal policies in stabilizing the us economy for instance the 2007 2009 large increase in expenditure to gdp ratios was apparently determined by the adverse non policy shocks that caused the recession

determinants of the current account balance in the united states this article studies the role of public and private imbalances in the behaviour of the current account balance in the united states in the context of an intertemporal model the estimation evaluates the effects of public and private imbalances on the dynamics of the current account correlation coefficients support the ricardian equivalence higher budget deficit correlates with a reduction in private consumption and an increase in private savings government saving does not vary significantly with macroeconomic variables in the short or in the long run in contrast fluctuations in government investment vary significantly with a number of economic variables in the long and in the short run accordingly fluctuations in the budget deficit are likely to be driven by fluctuations in public investment in contrast to government savings private savings vary significantly with macro variables in the long and in the short run fluctuations in private investment appear less evident compared to that in privat

fiscal policy and liquidity traps with heterogeneous agents this paper explores global dynamics in a monetary model with limited asset market participation and the zero lower bound on nominal interest rates it is shown that a rise in government transfers to non ricardian consumers financed by debt based taxes to ricardian consumers is capable of escaping disinflationary paths typically convergent to a liquidity trap fiscal policy does not need to be unsustainable at the low inflation steady state to avoid liquidity traps as argued in the context of the standard single representative agent setup

the carbon curse are fuel rich countries doomed to high co2 intensities the carbon curse is a new theory related to but distinct from the resource curse it states that fossil fuel rich countries tend to follow more carbon intensive developmental pathways than if they were fossil fuel poor countries due to a hitherto unappreciated syndrome of causal mechanisms first fuel rich countries emit significant amounts of co2 in the extraction of fuel and through associated wasteful practices such as gas flaring second easy access to domestic fuel in such countries leads to crowding out effects for their energy mix and economic structure for example abundant oil may displace other fuels from the energy mix and lead to the dutch disease third fuel abundance weakens the economic incentive to invest in energy efficiency fourth governments in fuel rich countries are under considerable pressure to grant uneconomic fuel consumption subsidies which further augments the carbon intensity of their economic output due to the combined effect of these causal mechanisms it is genuinely difficult for fuel rich countries to evade carbon intensive developmental pathways and yet there are remarkable exceptions like norway such positive outliers indicate that the carbon curse is not destiny when appropriate policies are adopted

climate change policy in brazil and mexico results from the mit eppa model based on an in depth analysis of results from the mit economic projection and policy analysis eppa model of climate policies for brazil and mexico we demonstrate that commitments by mexico and brazil for 2020 made during the un climate meetings in copenhagen and cancun are reachable but they come at different costs for each country we find that brazil s commitments will be met through reduced deforestation and at no additional cost however mexico s pledges will cost 4 billion us dollars in terms of reduced gdp in 2020 we explore short and long term implications of several policy scenarios after 2020 considering current policy debates in both countries the comparative analysis of these two economies underscores the need for climate policy designed for the specific characteristics of each country accounting for variables such as natural resources and current economic structure our results also suggest that both brazil and mexico may face other environmental and economic impacts from stringent global climate policies affecting variables such as the value of energy resources in international trade

the fiscal state dependent effects of capital income tax cuts abstract using the post wwii data of u s federal corporate income tax changes within a smooth transition var this paper finds that the output effect of capital income tax cuts is government debt dependent it is less expansionary when debt is high than when it is low to explore the mechanisms that can drive this fiscal state dependent tax effect the paper uses a dsge model with regime switching fiscal policy and finds that a capital income tax cut is stimulative to the extent that it is unlikely to result in a future fiscal adjustment as government debt increases to a sufficiently high level the probability of future fiscal adjustments starts rising and the expansionary effects of a capital income tax cut can diminish substantially whether the expected adjustments are through a policy reversal or a consumption tax increase also a capital income tax cut need not always have large revenue feedback effects as suggested in the literature

infrastructure provision and macroeconomic performance this paper studies the differences between private and government provision of infrastructure capital utilization decisions and their differential role in determining market prices for capital goods under the two regimes of infrastructure provision serve as a critical transmission mechanism for fiscal policy a subsidy to private providers of infrastructure is preferable to direct government provision irrespective of how the subsidy or expenditure is financed the case for private provision is much stronger in economies characterized by high levels of congestion the choice between private and government provision also has a crucial effect on the design of optimal fiscal policy 2011 elsevier b v all rights reserved

when does government debt crowd out investment summary we examine when government debt crowds out investment for the us economy using an estimated new keynesian model with detailed fiscal specifications and accounting for monetary and fiscal policy interactions whether investment is crowded in or out in the short term depends on policy shocks triggering debt expansions higher debt can crowd in investment for cutting capital tax rates or increasing government investment contrary to the conventional view no systematic relationships between real interest rates and investment exist explaining why reduced form regressions are inconclusive about crowding out at longer horizons distortionary financing is important for the negative investment response to debt copyright 2013 john wiley sons ltd

the effects of government spending shocks on consumption under optimal stabilization abstract economic theory has yet to come up with a general guidance regarding the dynamic effects and welfare implications of shocks to public spending with the aim to provide a theoretical benchmark we analyse if a rise in private consumption following an exogenous rise in government spending is a feature of the economy under optimal stabilization in a standard new keynesian setting augmented for the presence of liquidity constrained agents and non separable preferences our results provide little evidence in support of a crowding in effect under timelessly optimal policy

emissions intensity targeting from china s 12th five year plan to its copenhagen commitment china is currently the world s largest single source of fossil fuel related co2 emissions in response to pressure from the international community and in recognition of its role in global climate change mitigation the chinese government has announced a series of climate policy commitments in both the copenhagen accord and its domestic 12th 5 year plan to gradually reduce emissions intensity by 2020 emissions intensity reduction commitments differ significantly from emission level reduction commitments that are commonly adopted by developed economies in this paper we investigate the economic implications of china s recent commitments to reduce emissions intensity and highlight the complexities involved in modelling intensity targets under uncertainty using g cubed an intertemporal computable general equilibrium model of the world economy we show that china s emissions intensity targets could be achieved with a range of low and high growth emissions level trajectories corresponding to low and high growth gdp scenarios which lead to different welfare consequences

location search costs and youth unemployment experimental evidence from transport subsidies do high search costs affect the labour market outcomes of jobseekers living far away from jobs i randomly assign transport subsidies to unemployed youth in urban ethiopia treated respondents increase job search intensity and are more likely to find good permanent jobs subsidies also induce a short term reduction in temporary work i use a high frequency phone call survey to track the trajectory of search behaviour over time to show that the subsidies significantly increased job search intensity and the use of formal search methods the evidence suggests that cash constraints cause young people to give up looking for good jobs too early

propagation mechanisms for government spending shocks a bayesian comparison the inability of a simple real business cycle model to predict a rise in consumption in response to increased government expenditures observed in many empirical studies has stimulated the development of alternative theories of government spending shocks using the bayesian approach we evaluate the quantitative performance of five extant models and find that neither of the considered transmission mechanisms for government spending helps improve the fit of the baseline model moreover we find that consumption decreases in all estimated models in response to a rise in government spending

the lot of the unemployed a time use perspective this paper provides new evidence on time use and subjective well being of employed and unemployed individuals in 14 countries we devote particular attention to characterizing and modeling job search intensity measured by the amount of time devoted to searching for a new job job search intensity varies considerably across countries and is higher in countries that have higher wage dispersion we also examine the relationship between unemployment benefits and job search

fiscal policy pricing frictions and monetary accommodation this paper empirically investigates whether the theoretical conditions for government expenditure expansions to be effective hold for the data we ask whether the necessary conditions for fiscal effectiveness are relevant on average and in special circumstances that capture features of the recent crisis fiscal policy can be an effective countercyclical tool if monetary policy accommodates the fiscal expansion if expectations about future output growth and inflation are constant and if structural relationships are invariant to the policy change recent expansions are unlikely to produce large output multipliers or have important debt or inflation effects credible deficit and debt reduction schemes can produce sizeable output multipliers fabio canova and evi pappa

fiscal federalism and monetary unions a quantitative assessment abstract in this paper i provide a quantitative analysis of three different forms of fiscal federalism in monetary unions fully decentralized regional fiscal authorities as the benchmark fiscal equalization with nominal tax revenue sharing and a common central fiscal authority i assess the capability of the different arrangements to stabilize regional consumption output and employment over the business cycle i also study the implications for interregional income consumption risk sharing and welfare from this analysis the following results emerge first a central fiscal authority stabilizes consumption fluctuations and increases the scope of interregional income and consumption risk sharing second fiscal equalization destabilizes consumption fluctuations and also reduces the scope of interregional income and consumption risk smoothing third a central fiscal authority leads to welfare gains whereas fiscal equalization leads to welfare losses

government spending effects in low income countries abstract despite the voluminous literature on fiscal policy very few papers focus on low income countries lics this paper develops a new keynesian small open economy model to show analytically and numerically that several prevalent features of lics dependence on external financing public investment inefficiency and a low degree of home bias in public investment play important roles in government spending effects external financing increases the resource envelope mitigating the crowding out effects but it tends to appreciate the real exchange rate lowering traded output although capital scarcity in lics implies high returns to public capital low marginal investment efficiency can substantially dampen the output multiplier also public investment may not be effective in stimulating output in the short run as lics often rely on imports to a large extent to carry out public investment projects weakening its role as a short run demand stimulus

optimal simple monetary and fiscal rules under limited asset market participation the combination of limited asset market participation and consumption habits generates indeterminacy for empirically plausible calibrations of a business cycle model characterized by price and nominal wage rigidities equilibrium determinacy is restored by demand management policies based on simple fiscal rules in this regard fiscal control of nominal income growth is particularly effective in addition the complementarity between the taylor rule and the fiscal feedback on nominal income growth produces relatively large welfare gains limiting both aggregate and intragroup volatilities

keynesian government spending multipliers and spillovers in the euro area the global financial crisis has led to a renewed interest in discretionary fiscal stimulus advocates of discretionary measures emphasize that government spending can stimulate additional private spending the keynesian multiplier effect thus we investigate whether the spending package announced by euro area governments for 2009 and 2010 is likely to boost gdp by more than one for one because of modelling uncertainty it is essential that such policy evaluations be robust to alternative modelling assumptions and parameterizations we use five different empirical macroeconomic models with keynesian features such as price and wage rigidities to evaluate the impact of the fiscal stimulus four of them suggest that the planned increase in government spending will reduce private consumption and investment significantly only a model that largely ignores the forward looking behavioural response of consumers and firms implies crowding in of private spending we review a range of issues that may play a role in the recession of 2008 2009 implementation lags are found to reinforce crowding out and may even cause an initial contraction zero bound effects may lead the central bank to abstain from interest rate hikes and increase the gdp impact of government spending crowding in however requires an immediate anticipation of at least two years at the zero bound using a multi country model we find that spillovers between euro area countries are negligible or even negative because direct demand effects are offset by the indirect effect of a euro appreciation new keynesian dynamic stochastic general equilibrium dsge models provide a strong case for government savings packages announced with sufficient lead time spending cuts induce a significant short run stimulus and crowding in of private spending tobias cwik and volker wieland

designing an emissions trading scheme for china an up to date climate policy assessment abstract we assess recent chinese climate policy proposals in a multi region multi sector computable general equilibrium model with a chinese carbon emissions trading scheme ets when the emissions intensity per gdp in 2020 is required to be 45 lower than in 2005 the model simulations indicate that the climate policy induced welfare loss in 2020 measured as the level of gdp and welfare in 2020 under climate policy relative to their level under business as usual bau in the same year is about 1 the chinese welfare loss in 2020 slightly increases in the chinese rate of economic growth in 2020 when keeping the emissions target fixed at the 2020 level after 2020 in absolute terms the welfare loss will reach about 2 in 2030 if china s annual economic growth rate is 0 5 percentage points higher lower the climate policy induced welfare loss in 2030 will rise decline by about 0 5 percentage points full auctioning of carbon allowances results in very similar macroeconomic effects as free allocation but full auctioning leads to higher reductions in output than free allocation for ets sectors linking the chinese to the european ets and restricting the transfer volume to one third of the eu s reduction effort creates at best a small benefit for china yet with smaller sectoral output reductions than auctioning these results highlight the importance of designing the chinese ets wisely

can fiscal spending stimulate private consumption abstract empirically government expenditure shocks seem to crowd in private consumption while neoclassical and new keynesian models predict crowding out we derive conditions under which a government in utility specification in a sticky price model helps to reconcile theory and evidence

does home production replace consumption spending evidence from shocks in housing wealth in the great recession becker s theory of home production suggests substitutability between consumption spending and home production using panel data with detailed information on spending and time use we analyze househ

monetary fiscal policy interactions and fiscal stimulus abstract increases in government spending trigger substitution effects both inter and intra temporal and a wealth effect the ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption higher future taxes create a strong negative wealth effect while the active monetary response increases the real interest rate this paper estimates markov switching policy rules for the united states and finds that monetary and fiscal policies fluctuate between active and passive behavior when the estimated joint policy process is imposed on a conventional new keynesian model government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized the paper reports the model s predictions of the macroeconomic impacts of the american recovery and reinvestment act s implied path for government spending under alternative monetary fiscal policy combinations

the analytics of svars a unified framework to measure fiscal multipliers ticities implied by the identification schemes generate a large dispersion in the estimates of tax and spending multipliers second i estimate fiscal multipliers consistent with prior distributions of the elasticities computed by a variety of empirical strategies and by employing a simple dynamic stochastic general equilibrium model i document three findings for the u s for the period 1947 2010 first the impact tax multiplier is close to 0 second the impact spending multiplier ranges between 0 35 and 1 third there is a large uncertainty in the estimates of fiscal multipliers at longer horizons yet the probability that the spending multiplier is larger than the tax multiplier is above 0 65 for up to three years after policy interventions

the role of china in mitigating climate change abstract we explore short and long term implications of several energy scenarios of china s role in efforts to mitigate global climate risk the focus is on the impacts on china s energy system and gdp growth and on global climate indicators such as greenhouse gas concentrations radiative forcing and global temperature change we employ the mit integrated global system model igsm framework and its economic component the mit emissions prediction and policy analysis eppa model we demonstrate that china s commitments for 2020 made during the un climate meetings in copenhagen and cancun are reachable at very modest cost alternative actions by china in the next 10 years do not yield any substantial changes in ghg concentrations or temperature due to inertia in the climate system consideration of the longer term climate implications of the copenhagen type of commitments requires an assumption about policies after 2020 and the effects differ drastically depending on the case meeting a 2 c target is problematic unless radical ghg emission reductions are assumed in the short term participation or non participation of china in global climate architecture can lead by 2100 to a 200 280 ppm difference in atmospheric ghg concentration which can result in a 1 1 c to 1 3 c change by the end of the century we conclude that it is essential to engage china in ghg emissions mitigation policies and alternative actions lead to substantial differences in climate energy and economic outcomes potential channels for engaging china can be air pollution control and involvement in sectoral trading with established emissions trading systems in developed countries

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

comparing model results to national climate policy goals results from the asia modeling exercise abstract while the world has yet to adopt a single unified policy to limit climate change many countries and regions have adopted energy and climate policies that have implications for global emissions in this paper we discuss a few key policies and how they are included in a set of 23 energy and integrated assessment models that participated in the asia modeling exercise we also compare results from these models for a small set of stylized scenarios to the pledges made as part of the copenhagen accord and the goals stated by the major economies forum we find that the targets outlined by the united states the european union japan and korea require significant policy action in most of the models analyzed for most of the models in the study however the goals outlined by india are met without any climate policy the stringency of climate policy required to meet china s copenhagen pledges varies across models and accounting methodologies

unemployment market work and household production time diary data from four countries suggest that differences in market time between the unemployed and employed represent additional leisure not increased household production in areas where unemployment is cyclically high however reduced market work is offset by additional home production

the effects of discretionary fiscal policy on macroeconomic aggregates a reappraisal fiscal stimuli to recover a cascade of academic and layman articles debate the effectiveness of fiscal policy in stimulating the economy backed up by different economic models and empirical support this essay surveys the theoretical predictions and recent empirical vector autoregression var evidence on the short run effects of discretionary fiscal policy on macroeconomic aggregates

dynamic scoring a back of the envelope guide abstract this paper uses the neoclassical growth model to examine the extent to which a tax cut pays for itself through higher economic growth the model yields simple expressions for the steady state feedback effect of a tax cut the feedback is surprisingly large for standard parameter values half of a capital tax cut is self financing the paper considers various generalizations of the basic model including elastic labor supply general production technologies departures from infinite horizons and non neoclassical production settings it also examines how the steady state results are modified when one considers the transition path to the steady state

fiscal policy banks and the financial crisis this paper studies the effectiveness of euro area ea fiscal policy during the recent financial crisis using an estimated new keynesian model with a bank a key dimension of policy in the crisis was massive government support for banks that dimension has so far received little attention in the macroeconomics literature we use the estimated model to analyze the effects of bank asset losses of government support for banks and other fiscal stimulus measures in the ea our results suggest that support for banks had a stabilizing effect on ea output consumption and investment increased government purchases helped to stabilize output but crowded out consumption higher transfers to households had a positive impact on private consumption but a negligible effect on output and investment banking shocks and increased government spending explain half of the rise in the public debt gdp ratio since the onset of the crisis

real government size automatic feedback rules and the measured effectiveness of fiscal policy this paper argues that as intervention fiscal policy means more than simply any change in government spending and this requires of fiscal analysis a measure that separates the allocative from the counter cyclical activities of government defining intervention as an optimal policy rule that responds automatically to privately unanticipated variations in output a general equilibrium model is built to separate the supply side effects of desired changes in the size of government from demand side interventions designed to stimulate aggregate demand the model is tested using the results of a public choice investigation of the real size of government ferris and west 1996 that exercise produces a measure of desired size and through its residual an implicit measure of intervention the paper tests the prediction that increases in desired size increase aggregate supply and that ex post measures of fiscal intervention can be recovered and tested for their effect on aggregate output the test uses citibase

rule of thumb consumers productivity and hours in this paper we study the transmission mechanism of productivity shocks in a model with rule of thumb consumers in the literature this nancial friction has been studied only with reference to scal shocks we show that the presence of rule of thumb consumers is also very helpful in accounting for recent empirical evidence on productivity shocks rule of thumb agents together with nominal and real rigidities play an important role in reproducing the negative response of hours and the delayed responses of output and

job search and unemployment insurance new evidence from time use data article i nfo this paper provides new evidence on job search intensity of the unemployed in the u s modeling job search intensity as time allocated to job search activities the major findings are 1 the average u s unemployed worker devotes about 41 min to job search on weekdays which is substantially more than their european counterparts 2 workers who expect to be recalled by their previous employer search substantially less than the average unemployed worker 3 across the 50 states and d c job search is inversely related to the generosity of unemployment benefits with an elasticity between 1 6 and 2 2 4 job search intensity for those eligible for unemployment insurance ui increases prior to benefit exhaustion and 5 time devoted to job search is fairly constant regardless of unemployment duration for those who are ineligible for ui

fiscal policy and monetary integration in europe fiscal policy economists policy makers and the media often argue that the maastricht treaty and the stability and growth pact make it difficult for governments of emu countries to stabilize their economies with appropriate fiscal policy and to provide adequate public investment our empirical analysis offers little support to this view discretionary budget deficits have actually become more counter cyclical in emu countries after the maastricht treaty as well as in the other eu and non eu industrialized countries we study and while public investment has declined recently in emu countries a similar tendency is apparent in other countries and started well before the maastricht treaty was signed jordi gali and roberto perotti

fiscal stimulus and the role of wage rigidity abstract in this paper we study the impact of an expansion in public spending in an economy characterized by limited asset market participation and sticky wages the flexible wage version of the model implies strong expansionary effects on output and consumption but also a counterfactual increase in real wages the introduction of sticky wages besides being a realistic addition solves this problem and preserves the expansionary effects on output and consumption moreover once we introduce segmentation in the labor market sticky wages are even essential to obtain expansionary effects

effective tax rates in macroeconomics cross country estimates of tax rates on factor incomes and consumption abstract this paper proposes a method for computing tax rates using national accounts and revenue statistics using this method we construct time series of tax rates for large industrial countries the method identifies the revenue raised by different taxes at the general government level and defines aggregate measures of the corresponding tax bases this method yields estimates of effective tax rates on factor incomes and consumption consistent with the tax distortions faced by a representative agent in a general equilibrium framework these tax rates compare favorably with existing estimates of marginal tax rates and highlight important international differences in tax policy

liquidity constraints and the substitutability between private and government consumption the role of military and non military spending i introduction using data for a number of economies we investigate i the relationship between private consumption and two types of government spending military and non military and ii the severity of liquidity constraints because of their importance for macroeconomic modeling in theory and practice 1 both issues have been the subjects of considerable theoretical and empirical investigation on the issue of liquidity constraints the most influential research has relied on hall s 1978 euler equation approach to the permanent income hypothesis in an attempt to reconcile hall s and flavin s 1981 methodologies hayashi 1982 modified hall s martingale result to allow for the possibility that a subset of consumers are liquidity constrained and showed that liquidity constraints can result in consumption s excess sensitivity to current income campbell and mankiw 1989 1990 1991 and jappelli and pagano 1989 have applied hayashi s methodology using data from the u s and several other oecd countries on the substitutability issue aschauer 1985 has modified hall s euler equation to allow for substitutability between government spending and private consumption and found that the two are substitutes for the u s karras 1994 however using a similar approach and data for 30 countries concludes that private and government consumption are better described as complementary or unrelated liquidity constraints and substitutability have been combined in studies by graham and himarios 1991 cushing 1992 and graham 1993 using u s data and by evans and karras 1996 for a number of countries a crucial limitation of most of these studies is the use of aggregate government consumption data which counterintuitively imposes a common substitutability parameter on all components of government spending 2 using recently available time series data for a large number of countries the present paper relaxes this restriction by decomposing government consumption into military and non military components enabling us to separately identify their relationship to private consumption the allocation of government consumption between military and non military functions has varied greatly across countries the appendix reports the average size of military and non military government shares in gdp as well as the military non military ratio by country over the 1970 1989 period average military expenditure as a fraction of gdp for example has ranged in our sample from 0 11 in mexico to 12 30 in jordan similarly the fraction of government consumption absorbed by military expenditure has ranged from 1 09 in mauritius to 66 82 in poland this sizable variability is promising in terms of cross sectional identification power but it also suggests that the estimated parameters must not be assumed to be common across countries the estimated model is derived in section ii which combines liquidity constraints and substitutability by nesting the approaches of hayashi 1982 and aschauer 1985 in the same section we discuss data sources and the estimation strategy which permits the estimated parameters to vary by country in a way that helps determine how they are influenced by country specific factors section iii estimates the model for a panel of the 66 countries for which annual data on all series are available for the 1970 1989 period the paper s main conclusions are given in section iv ii methodology and data we assume that consumers in economy i at time t derive utility from effective consumption c sup which we define as 1 mathematical expression omitted where c is private consumption g sup m and g sup nm are the military and non military components of government consumption the parameters theta sup m and theta sup nm measure the degree of substitutability between c and g sup m and c and g sup nm respectively

search nash bargaining and rule of thumb consumers abstract this paper analyses the effects of introducing two typical keynesian features namely rule of thumb rot consumers and consumption habits into a standard labour market search model rot consumers use the margin that hours and wage negotiation provides them to improve their lifetime utility by narrowing the gap in utility with respect to ricardian consumers this margin for intertemporal optimisation has not been studied yet because this class of restricted agents has been mainly used in models with no equilibrium unemployment our approach allows for a deeper study of the effects of shocks on vacancies unemployment hours wages and how they interact as habits increase rot consumers find it optimal after a positive technology shock to negotiate lower hours and higher wages and this mechanism reduces the simulated correlation between the real wage or productivity and total hours to values closer to those obtained empirically thus with the interaction of rot consumers and consumption habits the labour market search model improves significantly in reproducing some of the stylised facts characterising the us labour market

government investment and fiscal stimulus effects of government investment are studied in an estimated neoclassical growth model the analysis focuses on two dimensions that are critical for understanding government investment as a fiscal stimulus implementation delays for building public capital and expected fiscal adjustments to deficit financed spending implementation delays can produce small or even negative labor and output responses to increases in government investment in the short run anticipated fiscal adjustments matter both quantitatively and qualitatively for long run growth effects when public capital is insufficiently productive distorting financing can make government investment contractionary at longer horizons

fiscal news and macroeconomic volatility abstract this paper analyzes the contribution of anticipated capital and labor tax shocks to business cycle volatility in an estimated new keynesian business cycle model while fiscal policy accounts for about 15 of output variance at business cycle frequencies this mostly derives from anticipated government spending shocks tax shocks both anticipated and unanticipated contribute little to the fluctuations of real variables however anticipated capital tax shocks do explain a sizable part of inflation fluctuations accounting for up to 12 of its variance in line with earlier studies news shocks in total account for about 50 of output variance further decomposing this news effect we find permanent total factor productivity news shocks to be most important when looking at the federal level instead of total government the importance of anticipated tax and spending shocks significantly increases suggesting that fiscal policy at the subnational level typically counteracts the effects of federal fiscal policy shocks

large scale bond purchases in a currency union with segmentation in the market for government debt abstract the literature on large scale purchases of government debt emphasises the importance of bond market segmentation along the maturity dimension for their transmission this study investigates how another form of segmentation that we observe the segmentation of government bond markets across countries can be exploited by the central bank of a currency union in which fiscal coordination is not attainable it is shown first that under general conditions government bond purchases which lower bond yields have first order effects on demand and hence inflation through a fiscal channel even in the absence of heterogeneity in investment opportunities the total effect on aggregate demand can be broken down into an income from debt issuance effect and a primary surplus effect as a result the central bank is able to use government bond purchases to control the terms of trade and achieve asymmetric degrees of stimulus across the members of the currency union without a transfer of resources if there is cross country segmentation in bond markets and home bias in government spending the paper characterises the welfare optimising mix of conventional interest rate policy and bond purchases in this scenario and gives an upper bound on the welfare benefits from using the additional tool

limited asset market participation and the consumption real exchange rate anomaly under efficient consumption risk sharing as assumed in standard international business cycle models a country s aggregate consumption rises relative to foreign consumption when the country s real exchange rate depreciates yet empirically relative consumption and the real exchange rate are essentially uncorrelated i show that this consumption real exchange rate anomaly can be explained by a simple model in which a subset of households trade in complete financial markets while the remaining households lead hand to mouth htm lives htm behavior also generates greater volatility of the real exchange rate and of net exports which likewise brings the model closer to the data

the rise of risk based pricing of mortgage interest rates in italy abstract this paper assesses how much mortgage interest rates in italy are priced on credit risk as proxied by the probability of household mortgage delinquency estimated using the eu silc database owing to data availability we restrict the analysis of mortgage pricing to italian households consistent with the more widespread use of credit scoring estimates indicate that italian lenders have increasingly priced mortgage interest rates on household credit risk for mortgages granted between 2000 and 2007 we find that a 1 point increase in the probability of default is associated with a 21 basis point rise in mortgage interest rates lower than the 38 basis point premium edelberg 2006 estimated for the us at the end of the 1990s

tax reform and labour market performance in the euro area a simulation based analysis using the new area wide model in this paper we employ a calibrated two country version of the new area wide model nawm developed at the european central bank to examine the potential benefits and spillovers of reducing labour market distortions caused by euro area tax structures our analysis shows that lowering tax distortions to levels prevailing in the united states would result in an increase in hours worked and output by more than 10 at the same time tax reductions would have positive spillovers to the euro area s trade partners bolstering the case for tax reforms from a global perspective finally we illustrate that in the presence of heterogeneous households distributional effects may be of importance when gauging the impact of tax reforms

debt dependent effects of fiscal expansions abstract economists often postulate that fiscal expansions are less stimulative when government debt is high than when it is low empirical evidence however is ambiguous using a nonlinear neoclassical growth model we show that the difference in government spending effects between high and low debt environments depends on the wealth effect on labor supply and on whether the government uses taxes or spending to retire debt because of interrelated state variables structural var estimations conditioning on debt alone can fail to isolate debt dependent effects also uncertainty on when the government will conduct fiscal consolidations generates wide confidence bands for spending multipliers further complicating efforts to estimate debt dependent government spending effects

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

time use emotional well being and unemployment evidence from longitudinal data how do unemployed individuals allocate and experience their time how does their time use and emotional experience change once they find a job this article provides new evidence on the time use and emotional well being of unemployed and employed individuals in the united states using longitudinal data from a survey of unemployed workers in new jersey we find evidence that the time spent on home production activities drops sharply at the time of reemployment with the magnitude of the shift in line with previous research using cross sectional time use surveys burda and hamermesh 2010 krueger and mueller forthcoming 1 leisure activities also decrease at the time of reemployment though somewhat less than in cross sectional time use data partly because those finding a job were spending more time on job search activities in the weeks prior to reemployment we also investigate the relationship between unemployment and emotional well being in connection with time use despite the fact that the unemployed spend relatively more time in leisure related activities we find that the unemployed enjoy these activities to a lesser degree

estimating the effects of coordinated fiscal actions in the euro area abstract we estimate spillover effects of a fiscal shock in one member country in the euro area on outputs of the rest of the members using a global vector autoregression gvar model we compare the effects of a domestic fiscal shock with those of a similar size area wide shock expressed as a weighted average of the fiscal shocks across all member countries according to our estimates the impact of an area wide fiscal shock on output of a member country tends to be positive and larger than that of a domestic shock since the cost of participating in the area wide shock is lower than the cost of a similar size domestic shock our finding indicates the importance of coordinated fiscal actions in the euro area

fiscal policy and occupational employment dynamics we document substantial heterogeneity in occupational employment dynamics in response to government spending shocks in the united states employment rises most strongly in service sales and office pink collar occupations by contrast employment in blue collar occupations is hardly affected by fiscal policy we provide evidence that occupation specific changes in labor demand are key for understanding these findings we develop a business cycle model that explains the heterogeneous occupational employment dynamics as a consequence of composition effects due to heterogeneous employment changes across industries and occupation specific within industry employment shifts due to differences in the short run substitutability between labor and capital services across occupations

escaping expectation traps how much commitment is required we study the degree of precommitment that is required to eliminate multiplicity of policy equilibria which arise if the policy maker acts under pure discretion we apply a framework developed by schaumburg and tambalotti 2007 and debertoli and nunes 2010 to a standard new keynesian model with government debt we demonstrate the existence of expectation traps under limited commitment and identify the minimum degree of commitment which is needed to escape from these traps we find that the degree of precommitment which is sufficient to generate uniqueness of the pareto preferred equilibrium requires the policy maker to stay in office for a period of two to five years this is consistent with monetary policy arrangements in many developed countries

cyclical effects of government s employment and goods purchases distinguishing between the goods purchase and employee compensation components of government spending is important shocks to government goods purchases and shocks to government employment have the opposite effects on private output private employment and private investment moreover with this distinction in place quantitative analysis reveals that government spending is no longer a significant driving source of the u s business cycle on the contrary the components of government spending are procyclical in the u s data primarily because of their positive responses to the output fluctuations generated by technology shocks copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

limited asset market participation and the euro area crisis an empirical dsge model we estimate a medium scale dynamic stochastic general equilibrium model for the euro area with limited asset market participation lamp our results suggest that in the recent european monetary union years lamp is particularly sizable 39 during 1993 2012 and important to understand business cycle features the bayes factor and the forecasting performance show that the lamp model is preferred to its representative household counterpart in the representative agent model the risk premium shock is the main driver of output volatility in order to match consumption correlation with output in the lamp model this role is played by the investment specific shock because non ricardian households introduce a keynesian multiplier effect and raise the correlation between consumption and investments we also detect the contractionary role of monetary policy shocks during the post 2007 years in this period consumption of non ricardian households fell dramatically but this outcome might have been avoided by a more aggressive policy stance jel c11 c13 c32 e21 e32 e37

pre announcement and timing the effects of a government expenditure shock abstract an econometric strategy to identify a pre announced fiscal policy shock is proposed i show that the reduced form innovations can be recovered by estimating a vector moving average model using the kalman filter the structural effects are identified exploiting the shock s pre announced nature which leads to potentially different signs of the responses of some endogenous variables during the announcement and after the realization of the shock i illustrate my strategy by identifying a pre announced shock to government consumption expenditures i find that the response of private consumption is significantly negative on impact rises and becomes significantly positive two quarters after the realization of the policy shock

government spending shocks and rule of thumb consumers with steady state inequality in the body of literature concerning fiscal policy a central result is that government spending might stimulate private consumption because only some households save while others spend their entire income each period although such heterogeneity naturally causes inequality this complication is commonly avoided by assuming that transfers redistribute steady state wealth i show that this steady state assumption drives short run results without redistribution the equilibrium is indeterminate and the labor market structure that is imposed to support the expansive result is theoretically inconsistent on a more positive note i propose a labor market formulation under which the expansive effects of government spending might arise

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

great expectations and the end of the depression what ended the great depression in the united states this paper suggests that the recovery was driven by a shift in expectations this shift was triggered by president franklin delano roosevelt s fdr policy actions on the monetary policy side roosevelt abolished the gold standard and announced an explicit policy objective of inflating the price level to pre depression levels on the fiscal policy side roosevelt expanded real and deficit spending which helped make his policy objective credible the key to the recovery was the successful management of expecta tions about future policy roosevelt s rise to power is modeled as a policy regime change as in thomas sargent 1983 and peter temin and barry wigmore 1990 this paper formalizes temin and wigmore s argu ment in a repeated game setting using a dynamic stochastic general equilibrium dsge model and argues that the regime change can account for the recovery in the model a regime change means the elimination of certain policy dogmas that constrain the actions of the government the regime change generates an endogenous shift in expectations due to a coordination of mon etary and fiscal policy this coordination ended the great depression by engineering a shift in expectations from contractionary i e the private sector expected future economic contrac tion and deflation to expansionary i e the public expected future economic expansion and inflation the expectation of higher future inflation lowered real interest rates thus stimulating demand while the expectation of higher future income stimulated demand by raising permanent income

clearing up the fiscal multiplier morass bayesian prior predictive analysis of five nested dsge models suggests that model specifications and prior distributions tightly circumscribe the range of possible government spending multipliers multipliers are decomposed into wealth and substitution effects yielding uniform comparisons across models by constraining the multiplier to tight ranges model and prior selections bias results revealing less about fiscal effects in data than about the lenses through which researchers choose to interpret data when monetary policy actively targets inflation output multipliers can exceed one but investment multipliers are likely to be negative passive monetary policy produces consistently strong multipliers for output consumption and investment

carbon emissions in china how far can new efforts bend the curve while china is on track to meet its global climate commitments through 2020 china s post 2020 co2 emissions trajectory is highly uncertain with projections varying widely across studies over the past year the chinese government has announced new policy directives to deepen economic reform to protect the environment and to limit fossil energy use in china to evaluate how new policy directives could affect energy and climate change outcomes we simulate two levels of policy effort a continued effort scenario that extends current policies beyond 2020 and an accelerated effort scenario that reflects newly announced policies on the evolution of china s energy and economic system over the next several decades we perform simulations using the china in global energy model c gem a bespoke recursive dynamic computable general equilibrium model with global coverage and detailed calibration of china s economy and future trends importantly we find that both levels of policy effort would bend down the co2 emissions trajectory before 2050 without undermining economic development specifically in the accelerated effort scenario we find that coal use peaks around 2020 and co2 emissions level off around 2030 at 10 bmt without undermining continued economic growth consistent with china reaching the status of a well off society by 2050

government size and business cycle volatility how important are credit constraints in this paper we analyse how the availability of credit influences the relationship between government size as a proxy for fiscal stabilization policy and the amplitude of business cycle fluctuations in a sample of advanced oecd countries interpreting relatively low loan to value ratios as an indication of tight credit constraints we find that government size exerts a stabilizing effect on output and consumption growth fluctuations only when credit constraints are relatively tight our results provide support for the hypothesis that credit market frictions play a crucial role in the transmission of fiscal policy

the general equilibrium effects of fiscal policy estimates for the euro area abstract this paper describes a dynamic stochastic general equilibrium model featuring a fraction of non ricardian agents in order to estimate the effects of fiscal policy in the euro area the model takes into account distortionary taxation on labor and capital income and on consumption while expenditures are broken down into purchases of goods and services compensation of public employees and transfers to households a newly computed quarterly data set of fiscal variables is used our results point to the prevalence of mild keynesian effects of public expenditures in particular although innovations in fiscal policy variables tend to be rather persistent government purchases of goods and services and compensations for public employees have small and short lived expansionary effects on private consumption while innovations in transfers to households show a slightly more sizeable and lasting effect the effects are more significant on the revenue side decreases in labor income and consumption tax rates have sizeable effects on consumption and output while a reduction in capital income tax favors investment and output in the medium run finally our estimates suggest that fiscal policy variables contribute little to the cyclical variability of the main macro variables

public and private sector wages interactions in a general equilibrium model it is common wisdom that public sector wages are not determined in the same way as private sector wages at the same time the empirical evidence available for oecd countries finds a strong positive correlation between public and private sector wages in this paper we develop a model that is consistent with a political economy view of the determination of public sector wages and employment while being consistent with the said empirical evidence public finance constraints are crucial in booms governments expand employment and wages while in downturns lack of tax revenues forces the government to cut back the wage bill

constructing and estimating a realistic optimizing model of monetary policy abstract a dynamic stochastic general equilibrium dsge model with real and nominal both price and wage rigidities succeeds in capturing some key nominal features of u s business cycles additive technology shocks as well as multiplicative shocks are introduced and shown to be crucial monetary policy is specified as an interest rate targeting rule following developments in the structural vector autoregression var literature the interaction between real and nominal rigidities is essential to reproduce the liquidity effect of monetary policy the model is estimated by maximum likelihood on u s data and its fit is comparable to that of an unrestricted first order var besides producing reasonable impulse responses and second moments this model replicates a feature of u s business cycles never captured by previous research with dsge models that an increase in interest rates predicts a decrease in output two to six quarters in the future

on fiscal multipliers estimates from a medium scale dsge model this paper contributes to the debate on fiscal multipliers in the context of a structural model i estimate a micro founded dynamic stochastic general equilibrium model that features a rich fiscal policy block and a transmission mechanism for government spending shocks using bayesian techniques for us data

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

the savers spenders theory of fiscal policy the macroeconomic analysis of fiscal policy is usually based on one of two canonical models the barro ramsey model of infinitely lived families or the diamond samuelson model of overlapping generations this paper argues that neither model is satisfactory and suggests an alternative in the proposed model some consumers plan ahead for themselves and their descendants while others live paycheck to paycheck this model is easier to reconcile with the essential facts about consumer behavior and wealth accumulation and it yields some new and surprising conclusions about fiscal policy

disinflation inequality and welfare in a tank model we investigate the redistributive and welfare effects of disinflation in a two agent new keynesian tank model characterized by limited asset market participation lamp and wealth inequality we highlight two key mechanisms driving our long run results i the cash in advance constraint on firms working capital cia ii dividends endogeneity these two channels point in opposite directions lower inflation softens the cia and by raising labor demand lowers inequality but the disinflation also raises dividends and this increases inequality the disinflation is always welfare improving for asset holders we obtain ambiguous results for non asset holders who suffer substantial consumption losses during the transition

fiscal policy in the new neoclassical synthesis we analytically derive the cyclical effects of fiscal policy shocks in a new neoclassical synthesis model price stickiness has the consequence that a rise in government demand affects labor demand while at the same time the usual wealth effect boosts labor supply the strength of the demand effect depends on the response of the real interest rate governed by the monetary policy regime when the central bank controls money growth fiscal expansions are deflationary and might even be contractionary whereas output wages and inflation can increase when the rise in the real interest rate is dampened by an interest rate rule however price stickiness alone is not sufficient to explain a rise in consumption as predicted by keynesian theory

monetary policy effects new evidence from the italian flow of funds new evidence on the transmission of monetary policy to the economy is provided through an analysis of the effects of a restrictive monetary policy shock on italian flow of funds over the period 1980 to 2002 firms reduce issuance of debt and decrease the acquisition of financial assets providing no support for the existence of strong financial frictions following the shock in the first quarter households increase short tem liabilities and diminish the acquisition of liquid assets and shares the public sector increases net borrowing during the first 2 years financial corporations decrease their borrowing for three quarters while in the same period the foreign sector increases borrowed funds we claim that our results shed new light on the role of the financial decisions of the economic sectors in the transmission mechanism of monetary policy

labor market heterogeneity aggregation and policy in variance of dsge model parameters data from a heterogeneous agents economy with incomplete asset markets and indivisible labor supply are simulated under various fiscal policy regimes and an approximating representative agent model is estimated preference and technology parameter estimates of the representative agent model are not invariant to policy changes and the bias in the representative agent model s policy predictions is large compared to predictive intervals that reflect parameter uncertainty since it is not always feasible to account for heterogeneity explicitly it is important to recognize the possibility that the parameters of a highly aggregated model may not be invariant with respect to policy changes

can public spending boost private consumption this paper analyses the effects on private consumption from an increase in productive and unproductive public spending a new keynesian model incorporating price and wage rigidities monetary policy and various fiscal rules is developed and estimated using bayesian techniques to capture the key cyclical characteristics of the us economy we find that price and wage rigidities along with a positive shock to the part of public spending that is productive are suficient to boost private consumption moreover we show that this initial positive reaction of private consumption is adequate to create a positive present value consumption multiplier for more than five years finally we show that our main results remain robust to changes in the monetary rule and the various methods of deficit financing
