This paper examines the interactions between multiple national fiscal policymakers and a single monetary policy maker in response to shocks to government debt in some or all of the countries of a monetary union. We assume that national governments respond to excess debt in an optimal manner, but that they do not have access to a commitment technology. This implies that national fiscal policy gradually reduces debt: the lack of a commitment technology precludes a random walk in steady-state debt, but the need to maintain national competitiveness avoids excessively rapid debt reduction. If the central bank can commit, it adjusts its policies only slightly in response to higher debt, allowing national fiscal policy to undertake most of the adjustment. However, if it cannot commit, then optimal monetary policy involves using interest rates to rapidly reduce debt, with significant welfare costs. We show that in these circumstances the central bank would do better to ignore national fiscal policies in formulating its policy.  相似文献

Financial frictions differ across countries and thus cause international differences in the transmission of shocks. This paper shows how the optimal mix of monetary and fiscal policy depends on these country-specific financial frictions. To this end, we build a two-country DSGE-model of a monetary union. Financial frictions are captured by the cost channel approach. We show that the traditional solution to the assignment problem – the common central bank stabilizes the inflation rate at the union level and the national fiscal authorities stabilize the national economies – does not hold in a world with financial frictions. The cost channel decreases the efficiency of monetary policy and increases the need for fiscal stabilization even at the union level. Moreover, the more heterogeneous the union, the more important is fiscal policy in stabilizing shocks. Finally, we evaluate the scenarios in terms of welfare of the representative household.  相似文献

We build an euro-area level DSGE model featuring a liquidity shock in the sovereign bonds market to simulate the strong contraction in economic activity observed during the 2008–2009 crisis. In the model, a sudden deterioration of the liquidity property of sovereign bonds is associated with deep recession and deflation. Against this background we characterize optimal monetary and fiscal policy with full commitment. We find that the optimal policy contains three features: (i) the policy rate is lowered until hitting the zero lower bound (ZLB) and then is kept at the ZLB for more periods; (ii) a prolonged central bank’s balance-sheet expansion aimed at restoring the liquidity deteriorated; (iii) a counter-cyclical fiscal stimulus which offsets, to a large extent, the fall in private spending caused by the liquidity shock. Policy regimes involving (i), but not (ii) and (iii), are quite weak in stabilizing output gap and inflation. Monetary policy regimes such as full inflation-targeting or nominal GDP targeting perform remarkably well insofar as they are complemented with an optimally-implemented counter-cyclical fiscal policy. Our results tend to favour the view that, in case of recession, an euro-wide coordinated fiscal policy should supplement the role of the ECB in achieving its primary objective.  相似文献

It is quite often claimed by politicians that a common currency makes it beneficial to be also endowed with a common fiscal policy. However, if fiscal policy can reasonably be considered to be a source of shocks, national fiscal policies which are steered independently from each other are generally preferable because they allow the possibility to diversify macroeconomic risks. Abstracting from automatic stabilizers, this view is valid independent on whether the ECB targets money growth or interest rates.

Using a two‐country DSGE model, we analyse the spillover effects of fiscal policy in a monetary union. Based on a non‐Walrasian labour market with a labour force participation decision and involuntary unemployment and a detailed fiscal sector, we focus on the relative cross‐border effects of different kinds of fiscal shocks (government expenditure and tax shocks). Among the major lessons from this analysis, five general and striking results are worth highlighting : (1) spillover effects differ widely according to the fiscal instrument, (2) all fiscal instruments produce positive spillover effects on foreign GDP except a rise in government consumption, (3) the response of unemployment is not always negatively correlated with the response of output (4) the different fiscal shocks trigger different effects on foreign inflation and the term of trade, which implies heterogeneous interest‐rate and trade channels, and (5) a more accommodative monetary policy and a scenario of ‘fiscal dominance’ alter greatly the effects of fiscal policy shocks.  相似文献

It is believed that a common monetary policy in a monetary union will have identical effects on different countries as long as these countries have identical fundamentals. We show that, when there is specialization in production, the terms of trade react to the shock. The transmission mechanism of a monetary shock has in this case an additional channel, the terms of trade. This is the case even if state contingent assets can be traded across countries. For a reasonable parametrization, the differential on the transmission across countries is quantitatively significant when compared with the effect on the union's aggregates. Monetary shocks create cycles with higher volatility in “poor” countries than in “richer” ones.  相似文献

Good economic management depends on understanding shocks from monetary policy, fiscal policy and other sources affecting the economy and their subsequent interactions. This paper presents a new methodology to disentangle such shocks in a structural VAR framework. The method combines identification via sign restrictions, cointegration and traditional exclusion restrictions within a system which explicitly models stationary and non-stationary variables and accounts for both permanent and temporary shocks. The usefulness of the approach is demonstrated on a small open economy where policy makers are actively considering the interaction between monetary and fiscal policies.  相似文献

The paper examines simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of Ricardian equivalence. Under this assumption, government debt turns into a relevant state variable which needs to be accounted for in the analysis of equilibrium dynamics. The key analytical finding is that without explicit reference to the level of government debt it is not possible to infer how strongly the monetary and fiscal instruments should be used to ensure determinate equilibrium dynamics. Specifically, we identify bifurcations associated with threshold values of steady-state debt, leading to qualitative changes in the local determinacy requirements.  相似文献

We construct a model of the international transmission of ‘liquidity trap’ shocks, and examine the case for international coordination of fiscal policy to respond to the liquidity trap. Integrated financial markets tend to propagate liquidity traps. In a global environment, fiscal policy may be effective in raising GDP when the economy is stuck in a liquidity trap, but it does so in a ‘beggar thy neighbor’ fashion; when one economy is in a liquidity trap, the cross country spillover effect of fiscal policy is negative. We examine the welfare optimizing policy response to a liquidity trap when countries coordinate on fiscal policy. Fiscal policy may be an effective tool in responding to a liquidity trap, although it is never optimal to use fiscal expansion sufficiently to fully eliminate a downturn. Moreover, there is little case for coordinated global fiscal expansion. For the most part, the country worst hit by a liquidity trap shock should use its own policies to respond, without much help from foreign policies.  相似文献

Search models of monetary exchange commonly assume that terms of trade in anonymous markets are determined via Nash bargaining, which generally causes monetary equilibrium to be inefficient. Bargaining frictions add to the classical intertemporal distortion present in most monetary models, whereby agents work today to obtain cash that can be used only in future transactions. In this paper, we study the properties of optimal fiscal and monetary policy within the framework of Lagos and Wright (2005). We show that fiscal policy can be implemented to alleviate underproduction while money is still essential. If lump sum monetary transfers are available, a production subsidy can restore the efficiency of monetary equilibria. The Friedman rule belongs to the optimal policy set, but higher inflation rates are also possible. When lump-sum monetary transfers are not available, equilibrium allocations are generally not first-best. Nevertheless, fiscal policy still results in substantial welfare gains. Money can be extracted from circulation via a sales tax on decentralized market activities, and the Friedman rule is only optimal if the buyer has relatively low bargaining power.  相似文献

This paper characterizes rules-based fiscal policy setting for G-3 and large EMS countries. We set up a simple fiscal policy rule and then infer on the policymakers’ reaction coefficients by testing with GMM. Our results qualify existing evidence on systematic fiscal policy in two respects. First, fiscal policy usually stabilizes public debt; and there is indeed substantial interaction between fiscal and monetary policies via the policy mix or the debt channel. Second, sustainability is achieved with a “stop–go” cycle of consolidation. Unless debt ratios are high, consolidation does not come at the cost of less cyclical stabilization.  相似文献

Using a post Keynesian model, this study aims to analyze the stabilizing role of fiscal and monetary policies in an open economy with a managed exchange rate regime. The real exchange rate is modeled as an endogenous variable and inflation explained using the conflicting claims approach. The dynamic properties of macroeconomic equilibrium are evaluated in different regimes of fiscal and monetary policies. The main result of this study suggests that the preferred policy regime is the one in which economic authorities are complementary and fiscal policy plays an explicitly active role. In this regime, the fiscal policy must commit to the target for the rate of capacity utilization and the monetary authority must commit to the inflation target.  相似文献

This paper develops and estimates a new-Keynesian dynamic stochastic general equilibrium (DSGE) model for the analysis of fiscal policy in the UK. We find that government consumption and investment yield the highest GDP multipliers in the short-run, whereas capital income tax and public investment have dominating effect on GDP in the long-run. When nominal interest rate is at the zero lower bound, consumption taxes and public consumption and investment are found to be the most effective fiscal instruments throughout the analysed horizon, and capital and labour income taxes are established to be the least effective. The paper also shows that the effectiveness of fiscal policy decreases in a small open-economy scenario and that nominal rigidities improve effectiveness of public spending and consumption taxes, whereas decrease that of income taxes.  相似文献

This paper examines economic policy interactions in the Economic and Monetary Union when the assessment of cyclical conditions in real time is surrounded by uncertainty. On the basis of a simple stylised model it shows that with a Nash-type of interaction different views about the output gap on the side of the policy players—the Council of the European Union, the European Commission and the European Central Bank—can give rise to excessive activism with policy players pushing economic variables into opposite directions. It argues that the costs of such policy conflicts can be reduced by agreeing on a common assessment of the cycle, by constraining policy variables, and/or by increasing the weight of fiscally conservative institutions. An alternative option to sidestep policy conflicts ensuing from diverging views of the cycle is to take policy decisions sequentially, as is the case in a Stackelberg-type of interaction. The paper shows that for a given misperception of the cycle, the impact on the policy instruments and on output and inflation are generally smaller in the Stackelberg equilibrium as compared to a Nash outcome. Alternative allocations of roles—that is leader versus follower—are discussed and assessed.

Romer and Romer (2010) use the narrative record to generate a time series of exogenous shocks to fiscal policy. They report a tax multiplier of 3.0. We extend their analysis and allow for nonlinearities between their shocks and the effects on output by estimating a threshold regression model. Using Hansen’s (1997) procedure, we find the best fitting threshold is changes in the federal fund rate with a delay of two quarters. Moreover, we find that the tax multiplier is approximately 4.3 if accompanied by an accommodative monetary policy and approximately 1.2 under tight monetary policy.  相似文献

After the Great Recession, the Keynesian expansionary policy has been regarded as an effective measure, especially under imperfect financial market conditions. Among literature related to fiscal policy in financial crises, Fernández-Villaverde (2010) suggests that the fiscal policy multiplier increases in a financial crisis through the Fisher effect. However, we should note that the author simply compared the multiplier computed in the standard new Keynesian dynamic stochastic general equilibrium (DSGE) with that in the DSGE with financial accelerator settings. As the financial accelerator is considered effective during both financial crises and normal financial conditions, the author’s comparison should be considered insignificant for showing a greater multiplier in the financial crisis. In this study, to make the exact comparison, we first estimate parameters regarding the Fisher effect under each regime separately and then compute and compare the estimated fiscal multipliers using these 2 estimates in the same DSGE model. Using Japanese financial data that provide enough observations under the good and bad regimes of financial conditions, we find that fiscal multipliers are smaller in the bad regime than in the good regime.  相似文献

Using the concept of ex-post optimality, we compare different exchange rate regimes, including floating exchange rates and fixed exchange rates with a Monetary Union in a two country OLG model with stochastic endowments. The emphasis of this comparison is on the welfare consequences of agents having incorrect beliefs. We do not assume that agents can hold any beliefs, but rather that their beliefs are rational that is consistent with the observed empirical behavior of the economy. We study a large set of possible policies, but two of them have our particular interest. The first policy implies devaluations in reaction to a negative shock, while the other implies a fixed exchange rate. These policies have very different consequences. The first will for generic beliefs not result in an ex-post optimal allocation. The other policy is on the other hand always feasible and results in an ex-post optimal allocation. When the two countries form a Monetary Union, the ex-post optimal allocation is also achieved. The meaning of “endogenous uncertainty” as an institutionally induced uncertainty is illustrated.

In this article I develop an imperfectly competitive dynamic general equilibrium model for a small open economy integrated in a monetary union. Here, the type of entry in the non-traded goods’ sector affects fiscal policy effectiveness. Fiscal policy effectiveness is enlarged when aggregate demand stimuli increase intra-industrial competition (case I). This is due to the counter-cyclical mark-up mechanism generated by entry. Such a mechanism is absent in the usual monopolistic competition where entry only has a sharing effect (case II).

The inflation of the 1970s in the US is often discussed as if the only type of policy action that could have prevented the inflation were monetary policy actions and the only type of policy errors that might have induced the inflation were monetary policy errors. Yet fiscal policy underwent dramatic shifts in the 1970s and economic theory makes clear that in an environment of uncertainty about future fiscal policy, monetary policy instruments may lose potency or have perverse effects. This paper documents the vagaries of fiscal policy in this period and argues that people at the time must have been uncertain about fiscal policy's future course. It also lays out a theoretical framework for understanding the effects of fiscal uncertainties on monetary policy and shows that fiscal variables have predictive value in dynamic models, even if traditional monetary policy indicators are included in the system.  相似文献
