The Government Spending Multiplier in Turkey

This study aims to measure the size of the government spending multiplier in Turkey for post-2001 financial crisis period within a structural VAR framework. The analysis demonstrates that a positive shock to government spending tends to increase output, tax, and real interest rate on impact and the size of the fiscal multiplier is relatively large at first few quarters. The fiscal multiplier reaches a peak value of 1.5 at second quarter and then starts to diminish. Furthermore, investigating the effects of the components of government spending reveals the fact that government investment expenditures, rather than consumption expenditures, have a profound impact on output at first few quarters.     

Optimal Monetary and Fiscal Policy with a Zero Bound on Nominal Interest Rates

I characterize optimal monetary and fiscal policy in a stochastic New Keynesian model when nominal interest rates may occasionally hit the zero lower bound. The benevolent policymaker controls the short‐term nominal interest rate and the level of government spending. Under discretionary policy, accounting for fiscal stabilization policy eliminates to a large extent the welfare losses associated with the presence of the zero bound. Under commitment, the gains associated with the use of the fiscal policy tool remain modest, even though fiscal stabilization policy is part of the optimal policy mix.     

Fiscal Multipliers at the Zero Lower Bound: The Role of Policy Inertia

The presence of the lagged shadow policy rate in the interest rate feedback rule reduces the government spending multiplier nontrivially when the policy rate is constrained at the zero lower bound (ZLB). In the economy with policy inertia, increased inflation and output due to higher government spending during a recession speed up the return of the policy rate to the steady state after the recession ends, which in turn damps the expansionary effects of the government spending during the recession via expectations. In our baseline experiment intended to capture the effectiveness of the American Recovery and Reinvestment Act of 2009, the output multiplier at the ZLB is 1.9 when the weight on the lagged shadow rate is zero, and 0.5 when the weight is 0.85.     

Monetary conservatism and fiscal policy

Does an inflation conservative central bank à la Rogoff (1985) remain desirable in a setting with endogenous fiscal policy? To provide an answer we study monetary and fiscal policy games without commitment in a dynamic, stochastic sticky-price economy with monopolistic distortions. Monetary policy determines nominal interest rates and fiscal policy provides public goods generating private utility. We find that lack of fiscal commitment gives rise to excessive public spending. The optimal inflation rate internalizing this distortion is positive, but lack of monetary commitment generates too much inflation. A conservative monetary authority thus remains desirable. When fiscal policy is determined before monetary policy each period, the monetary authority should focus exclusively on stabilizing inflation. Monetary conservatism then eliminates the steady state biases associated with lack of monetary and fiscal commitment and leads to stabilization policy that is close to optimal.     

The Government Spending Multiplier in a (Mis)Managed Liquidity Trap

I study the impact of a government spending shock in a New Keynesian model when monetary policy is set optimally. In this framework, the economy is at the zero lower bound but expectations are well managed by the central bank. As such, the multiplier effect of government spending increases on expected inflation is close to zero while the one on output can be larger than one. This is consistent with recent empirical evidence on the effects of the 2009 American Recovery and Reinvestment Act.     

Monetary versus fiscal policy in India: an SVAR analysis

Conventionally, the policymakers relied on three policy alternatives to manage business cycles – debt-financed government spending, debt-financed tax rebate and interest rate. While the first two are fiscal policy instruments, the latter is a monetary policy instrument. This paper aims to capture interactions among Indian monetary and fiscal policy actions, and the impact of such policy actions on select macroeconomic variables for the period 1990Q1–2011Q4. The policy actions are identified using the sign restrictions approach combined with magnitude restrictions in a Structural Vector Autoregression framework, and interpreted using impulse responses and variance decomposition. The results show that Indian monetary policy responds to tax rebate shocks and spending shocks differently. In the case of a tax rebate shock, Indian monetary policy responds by reducing interest rates thereby accommodating fiscal expansion. On the opposite, monetary policy seems not to accommodate expenditure shocks. Interestingly, the monetary policy shock is accompanied by a fiscal expansion that threatens the credibility of the central bank actions, thus indicating fiscal policy dominance. A comparison of the efficacy of the policies suggests that the interest rate is more effective in stimulating output. Out of the two fiscal policy instruments analysed, the tax rebate seems to be the better option for stimulating output considering the output-debt trade-off.     

Fiscal policy and financial market movements

This paper estimates fiscal policy reaction function in order to investigate the links between financial market movements and fiscal policy outcomes. An increase in asset prices affects in a positive and significant manner primary balances, with the response reflecting both an increase in government revenues and a fall in government spending. The most important impact on fiscal balances is due to changes in residential property prices. Changes in equity and commercial property prices are also important determinants of fiscal balances. Our findings suggest that the steepening of the slope of the yield curve contributes to expenditure based fiscal discipline.     

Macroeconomic Effects of Government Spending: The Great Recession was (Really) Different

We estimate the effect of government spending shocks on the U.S. economy with a time‐varying parameter vector autoregression. The recent Great Recession period appears to be characterized by uniquely large impulse responses of output to fiscal shocks. Moreover, the particularity of this period is underlined by highly unusual responses of several other variables. The pattern of fiscal shock responses neither completely fits the predictions of the New Keynesian model of an economy subject to the zero lower bound on nominal interest rates, nor does it suggest regular variation of fiscal policy effects depending on the state of the business cycle. Rather, the Great Recession period seems special in that government spending shocks had a strongly negative effect on the spread between corporate and government bond yields and a strongly positive effect on consumer confidence and private consumption spending.     

Optimal fiscal and monetary policy with sticky prices

In this paper I consider the role of state-contingent inflation as a fiscal shock absorber in an economy with nominal rigidities. I study the Ramsey equilibrium in a monetary model with distortionary taxation, nominal non-state-contingent debt, and sticky prices. With sticky prices, the Ramsey planner must balance the shock absorbing benefits of state-contingent inflation against the associated resource misallocation costs. For government spending processes resembling post-war experience, introducing sticky prices generates striking departures in optimal policy from the case with flexible prices. For even small degrees of price rigidity, optimal policy displays very little volatility in inflation. Tax rates display greater volatility compared to the model with flexible prices. With sticky prices, tax rates and real government debt exhibit behavior similar to a random walk. For government spending processes resembling periods of intermittent war and peace, optimal policy displays extreme inflation volatility even when the degree of price rigidity is large. As the variability in government spending increases, smoothing tax distortions across states of nature becomes increasingly important, and the shock absorber role of inflation is accentuated.     

Fiscal Multipliers under an Interest Rate Peg of Deterministic versus Stochastic Duration

This paper revisits the size of the fiscal multiplier. The experiment is a fiscal expansion under the assumption of a pegged nominal rate of interest. We demonstrate that a quantitatively important issue is the articulation of the exit from the policy experiment. If the monetary‐fiscal expansion is stochastic with a mean duration of T periods, the fiscal multiplier can be unboundedly large. However, if the monetary‐fiscal expansion is for a fixed T periods, the multiplier is much smaller. Our explanation rests on a Jensen's inequality type argument: the deterministic multiplier is convex in duration, and the stochastic multiplier is a weighted average of the deterministic multipliers. The quantitative difference in the two multipliers also arises in a model with capital, and in the baseline nonlinear model. However, the differences between the two are less pronounced in the nonlinear models. The errors from a linear approximation are much larger for the stochastic exit model then for the deterministic exit model.     

Monetary Policy and Financial Markets at the Effective Lower Bound

I discuss what determines the effective lower bound (ELB) for the policy rate and argue that the ELB is not hard, but rather soft, and that it is probably slightly negative. I argue that, at the ELB, current output can be increased by (i) monetary policy that extends the period of credibly low policy rates and generates inflation expectations, (ii) financial‐stability policy—which is distinct from monetary policy—that reduces the spreads between market interest rates and the policy rate, and (iii) fiscal policy that increases the neutral real rate by reducing expected growth of government expenditure and increases potential output by increasing current government expenditure.     

Withering Government Spending Multipliers

The empirical literature has documented a weakening of the consumption and output responses to an increase in government spending during the last 30 years. We show that a New Keynesian model in which real government spending is observed with measurement errors can account for the reduction in the size of government spending multipliers. The model implies—consistent with empirical evidence presented by Ilzetzki, Mendoza, and Vegh (2010)—that the evolution of monetary policy and greater globalization (increasing international trade and decreasing capital controls) are key factors in this development.     

Interest rate rules and price determinacy: The role of transactions services of bonds

Interest rate rules have been associated with price indeterminacy when they do not respond aggressively enough to inflation. Price indeterminacy is typically associated with indeterminacy of real bond balances, suggesting that the missing element is a meaningful role for government bonds. We assume that government bonds provide arbitrarily small transactions services and show that this can dramatically change the local and global determinacy conditions. In particular, the specification of fiscal policy affects the aggressiveness with which monetary policy must respond to inflation to deliver local determinacy—a range of passive monetary policies, even an interest rate peg, may yield determinacy.     

Level,slope, curvature of the sovereign yield curve,and fiscal behaviour

We study fiscal behaviour and the sovereign yield curve in the US and Germany. We obtain the latent factors, level, slope and curvature, with the Kalman filter, and use them in a VAR with macro, fiscal and financial stress variables. In the US, fiscal shocks generate an immediate response of the short-end of the yield curve, associated with monetary policy, lasting 6–8 quarters, followed by a response of the whole yield curve lasting 3 years, with an implied elasticity of long-term yields of 80% for the government debt shock and 48% for the budget balance shock. In Germany, fiscal shocks have entailed no significant reactions of the yield curve shape and no response of the monetary policy interest rate, notably after 1999; only in the case of debt shocks there is a short-lived decrease in the medium-end of the yield curve in the following 2nd and 3rd quarters.     

Unemployment,Government Spending and the Laffer Effect*

The paper studies the effects of income tax rate changes in a general equilibrium model with frictional unemployment. Laffer curve effects, by which a tax rate reduction may increase the level of government spending or its share in output, are shown to be possible under certain conditions. These are the presence of unemployment benefit payments, government budget balance through fiscal spending adjustment and limited quantitative importance of labour reallocation costs. Endogenous government spending acts as a fiscal accelerator if the fiscal burden of unemployment benefit payments is large, but reduces the employment effects of tax rate cuts if it is low.     

The Effects of Social Spending on Economic Activity: Empirical Evidence from a Panel of OECD Countries*

The aim of this paper is to assess the short‐term effects of social spending on economic activity. Using a panel of OECD countries from 1980 to 2005, the results show that social spending has expansionary effects on GDP. In particular, we find that an increase of 1 per cent in social spending increases GDP by about 0.1 percentage points, which, given the share of social spending in GDP, corresponds to a multiplier of about 0.6. The effect is similar to that of total government spending, and it is larger in periods of severe downturns. Among spending subcategories, social spending on health and on unemployment benefits have the greatest effects. Social spending also positively affects private consumption, while it has negligible effects on investment. The empirical results are economically and statistically significant, and robust.     

Signals from the government: Policy disagreement and the transmission of fiscal shocks

We investigate the effects of fiscal policy communication on the propagation of government spending shocks. To this aim, we propose a new index measuring the coordination effects of policy communication on private agents׳ expectations. This index is based on the disagreement amongst US professional forecasters about future government spending. The underlying intuition is that a clear fiscal policy communication can coalesce expectations, reducing disagreement. Results indicate that, in times of low disagreement, the output response to fiscal spending innovations is positive and large, mainly due to private investment response. Conversely, periods of elevated disagreement are characterised by muted output response.     

Geographic Cross-Sectional Fiscal Spending Multipliers and the Role of Local Autonomy: Evidence from European Regions

Using a panel of 268 European regions during 1990–2014, we document that the degree of local government's autonomy, measured with the “Local Autonomy Index,” has a significant positive effect on the fiscal spending multiplier. The estimated geographic cross-sectional fiscal spending multiplier is on average close to zero in countries with the lowest degree of local autonomy, and around unity in countries with the highest degree of local autonomy. Multipliers are state-dependent: larger when gross domestic product is below trend and when there is slack in the labor market; in those states, local autonomy has a particularly large positive effect on the multiplier. To interpret the empirical findings, we build a Dynamic Stochastic General Equilibrium (DSGE) model where both local and central government spending contribute to a public good that enhances private labor productivity. Local governments are more efficient in producing the public good and the multiplier is higher in countries where local government spending has a larger share in the production of the public good.     

Interaction of Government Tiers and Central Banks in a Federation: An Empirical Test

Fiscal rules are necessary to protect monetary policy from the consequences of unsustainable or active fiscal policy for inflation. Monetary unions, such as the Economic and Monetary Union (EMU), require even stronger fiscal rules to avoid free riding by regional fiscal authorities on the common monetary policy. By contrast, in a fiscal federation, the federal government internalises the effect of active regional policies on the overall price level. Federal fiscal policy contributes to price stability either by enforcing fiscal rules or by adjusting its own stance. Following Canzoneri, Cumby and Diba (2001), we test whether federal and regional governments in Germany behave in an active or passive way. We find evidence of a spillover effect of unsustainable policies on other regions. The German federal government offsets the effect on the price level by running passive policies. The Bundesbank's prime objective of price stability is therefore endorsed by fiscal policy. The results have implications for the regulation of fiscal policies in the EMU.     

中国财政政策乘数效应分析

财政政策是逆周期宏观调控的重要举措,财政政策乘数高低体现了宏观政策的效果,对政府决策具有重要的参考价值.本文基于IS-LM的拓展模型,估计得到2002-2017年间的财政支出乘数在0.58到0.67之间,税收乘数在-0.22到-0.18之间,私人投资乘数在1.16到1.8之间,财政支出乘数较以往研究有较大的下降,沿用传统的刺激需求政策不可持续.通过对财政支出乘数传导机制的进一步研究发现,财政支出对居民消费的拉动作用在一定程度上被政府投资对消费的挤出效应所抵消,政府投资对私人投资的带动效应也受到财政支出挤出效应的抵消,宽松货币政策的配合可以减少财政支出挤出效应.最后基于分析给出相关政策建议.
