Fiscal policy reforms in general equilibrium: The case of Greece

This paper quantifies the macroeconomic and welfare implications of (i) changes in the tax-spending mix and (ii) debt consolidation policies. The setup is a neoclassical growth model augmented with a relatively rich public sector. The model is calibrated to the Greek economy. The results suggest that, if the goal of fiscal policy is to stimulate the economy and increase welfare by changing the tax mix, then it should decrease the tax rate on labour income and increase the consumption tax rate. While higher public investment spending is good for the economy, it is lower public consumption spending that is found to be expansionary. The results also suggest that both tax- and expenditure-based debt consolidation policies lead to worse economic activity in the short run, but they have strong beneficial effects in the medium and long run when the consolidation period finishes.     

Growth forecast errors and government investment and consumption multipliers

We compare government investment and consumption multipliers in developed economies during the initial years of the ongoing fiscal consolidation. We find that, in countries with high public debt, the investment multiplier is likely to be higher than what has been assumed by policy-makers and higher than the consumption multiplier. This leads to the conclusion that the consolidation should be accompanied by increased public investment.     

Government efficiency,institutions, and the effects of fiscal consolidation on public debt

We study the evolution of the ratio of public debt to GDP during 132 fiscal episodes in 21 OECD countries in 1981–2008. Our main focus is on debt dynamics during 40 consolidation periods. To define these periods we use data on the evolution of the underlying cyclically adjusted primary balance, and as such avoid biases that may be induced by one-off budgetary measures. The paper brings new evidence on the role of public sector efficiency for the success of fiscal consolidation. First, we confirm that consolidation programs imply a stronger reduction of the public debt ratio when they rely mainly on spending cuts, except public investment. Government wage bill cuts, however, only contribute to lower public debt ratios when public sector efficiency is low. Second, we find that a given consolidation program will be more effective in bringing down debt when it is adopted by a more efficient government apparatus. Third, more efficient governments adopt consolidation programs of better composition. As to other institutions, consolidation policies are more successful when they are accompanied by product market deregulation, and when they are adopted by left-wing governments. By contrast, simultaneous labor market deregulation may be counterproductive during consolidation periods.     

The effects of fiscal consolidations on the composition of government spending

ABSTRACT

In response to increasing debt paths, governments often implement fiscal consolidation programs. This paper studies the impact of these programs on the composition of government spending. System-GMM estimations performed on a sample of 53 developed and emerging countries over 1980–2011 reveal that fiscal consolidations significantly reduce the government investment-to-consumption ratio, i.e. a composition effect. Robust to a wide set of tests, including when using the narrative approach to identify fiscal consolidations, this significantly stronger contraction of government investment with respect to government consumption is at work particularly when debt is high and in the low phase of the economic cycle. Therefore, in such contexts, fiscal consolidations aimed at short-run stabilization may hurt the economy in the long-run through their detrimental effect on public investment, calling for a reflection upon how they could be re-designed to allow avoiding such undesirable consequences.     

A stochastic estimated version of the Italian dynamic General Equilibrium Model

This paper aims at identifying the main drivers of the Italian economic cycle. To this end, we estimate a small-open economy model based on a dual labor market, which captures the main features of the Italian economy. Our results indicate that labor market rigidities are important structural features of the Italian economy, but they provide a limited contribution in explaining the business cycle fluctuations. Long-term dynamics are mostly driven by supply factors (productivity and markups). However, demand factors, including monetary and fiscal policies, play a sizeable role in the short run. Policy experiments show that expansionary fiscal policies crowd out private consumption and investment. The paper also contributes to the recent debate on fiscal consolidation. Estimated fiscal multipliers support the view that plans aimed at reducing the public debt should be based on tax increases rather than expenditure cuts.     

Variation in the fiscal multiplier with the method of financing: evidence across industrial countries

Government spending has often varied with the business cycle to stimulate the economy and to revive economic conditions. However, the state of public finances has often necessitated higher borrowing to finance widening fiscal deficits. Indeed, recent austerity packages around the globe have crystalized the importance of fiscal consolidation against the backdrop of rising public debt. To shed light on recent debates regarding fiscal multipliers, the article estimates variation in these multipliers with the method of financing, using annual data for a sample of industrial countries. There is a large variation in the effects of expansionary and contractinary government spending shocks on economic variables within and across countries. The significant effects of negative government spending shocks (fiscal contraction) appear more prevalent than those of expansionary shocks on real output growth, price inflation and nominal wage inflation. Consistent with theory’s predictions, the fiscal multiplier is more likely to be negative when government spending is financed by issuing debt and less likely in the case of monetization. The evidence confirms concerns about the negative effect of higher debt and more expensive financing on private activity, countering the effectiveness of fiscal policy.     

Equitable fiscal consolidations

Empirical research has uncovered an equity-efficiency trade-off in alternative fiscal consolidation strategies. Spending-based adjustments are associated with more limited output losses but greater inequality than tax-based adjustments. Moreover, spending-based adjustments are less likely to be reversed, but an increase in inequality reduces the likelihood of achieving a successful consolidation. We investigate the issue of designing a debt consolidation plan which is achieved through a reduction in public consumption and yet is equitable because temporary targeted transfers and tax reductions stabilize consumption of the poorer part of the population. This causes a limited slow-down in the pace of debt reduction because fiscal multipliers associated to the tax/transfer policies are large.     

Algeria: A three-sector macrofiscal model for debt sustainability and growth policy analysis

In this paper, we present a dynamic general equilibrium (DGE) model to address the macrofiscal vulnerabilities and the effects of fiscal policy on growth and employment in Algeria. We first discuss the baseline scenario over the period 2021–2040. According to our baseline results, without fundamental changes in fiscal policies, even relatively high growth will not be sufficient to put public debt on a sustainable path. We then conduct four experiments and assess their impact on fiscal accounts, growth, and unemployment: an increase in the efficiency of public spending on infrastructure investment, a gradual reduction in the share of noninterest government spending in GDP, the same gradual reduction in spending combined with a permanent increase in the share of investment in infrastructure in total noninterest government expenditure, and a composite fiscal reform program that combines these individual policies, respectively. The results suggest that public debt sustainability can be achieved, and growth and employment can be promoted, as long as an ambitious fiscal reform program involving tax, spending, and governance reforms is implemented. Importantly, our quantitative analysis shows that, with a well-designed fiscal program, there may be no trade-off between fiscal consolidation and economic growth.     

Tales of fiscal adjustment

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.     

中国地方政府债务可持续、财政空间与经济增长*

根据Ghosh et al（2013）财政空间理论，利用2010—2019中国省级面板数据，对中国省级政府债务可持续、财政空间和经济增长之间的关系及其机制进行了研究。结果表明，中国个别省份出现了财政疲劳现象，要把控好债务风险雷区，但各地区债务限额存在异质性，在不损害可持续性的情况下，大部分地方政府有足够的“回旋余地”实施财政刺激政策。我国省级政府的财政空间和经济增长之间存在倒“U”型关系，即当政府负债率高于财政空间的临界点（或较低的财政空间）时开始阻碍经济增长，因此，需要通过降低政府负债率实现更高的增长。进一步研究发现，政府债务影响经济增长最重要的渠道是公共投资和私人投资，全要素生产率、储蓄和长期真实利率也是政府债务影响经济增长的重要渠道，而长期名义利率未能成为政府债务影响经济增长的渠道。     

Ricardian equivalence and the public and private saving nexus in India

This study tests the Ricardian equivalence theorem (RET) and examines the responsiveness of private saving to public saving in India. Most estimators do not provide support for the empirical validity of RET and long-run cointegration between public and private saving. The increases in household saving (HHS) seem to have been engendered by the provision of saving incentives, institution of saving schemes, self-driven motivation to save, and the precautionary accumulations induced by uncovered uncertainties in incomes, rather than by Ricardian behaviour of households. The self-imposed aversion to debt and debt bequest, borrowing and liquidity constraints, and the intertemporal smoothing of consumption have been the added catalysts that contributed to the increases in HHS. The households with binding borrowing constraints, inadequate or no insurance and uncovered uncertainties in incomes seem to have been saving more to pay for higher inflation-tax. The fiscal consolidation and generation of public saving are essential to reduce the tax burden (both explicit through fiscal taxes and implicit through inflation-tax), minimize the likelihoods of economic and financial crises, and maintain the internal and external value of domestic currency.     

Cross-border spill-overs from fiscal stimulus in a monetary union

We analyse domestic and cross-border effects of fiscal policy in a two-region business cycle model of a monetary union. Without relying on debt consolidation via spending reversals along the lines of Corsetti, Meier and Mueller (2010) and Corsetti and Mueller (2014) we show that a fiscal expansion by the core economies of the euro area is associated with crowding in of both core and periphery consumption. Interestingly, cross-border spill-over effects are larger the larger the share of credit constrained households in the periphery.     

Options and strategies for fiscal consolidation in India

This paper uses a multi-region dynamic stochastic general equilibrium (DSGE) model to study options and strategies for fiscal consolidation in India. The challenge for India is how to put public finances on a more sustainable footing while preserving the potential for high growth and attenuating the adverse consequences on the needy. We analyze the macroeconomic implications of three fiscal consolidation scenarios. A “benchmark” case based on authorities' intentions that reduces government consumption, general transfers, and strengthens consumption tax collection; a “growth-friendly” that reallocates the savings to more public investment; and a “social-friendly” scenario that equally reallocates the savings between more public investment and more transfers to households excluded from the financial system. The simulations indicate that fiscal consolidation yields considerable long-term benefits and also entails output costs in the near term. Growth outcomes are better under the growth-friendly and social-friendly scenarios. These consolidation scenarios alone are not enough to maximize net gains for India. Other factors, such as the pace of consolidation, the combination with structural reforms and external economic conditions, play a critical role in the success of fiscal consolidation.     

The macroeconomic effects of fiscal policy in Portugal: a Bayesian SVAR analysis

With a new quarterly dataset we estimate a Bayesian Structural Autoregression model and a Fully Simultaneous System approach to analyze the macroeconomic effects of fiscal policy. Results show that positive government spending shocks, in general, have a negative effect on real GDP; lead to “crowding-out” effects of private consumption and investment; have a persistent and positive effect on the price level and a mixed impact on the average financing cost of government debt. Explicitly considering the government debt dynamics in the model is also important. A VAR counter-factual exercise confirms that unexpected positive spending shocks create relevant “crowding-out” effects.     

Fiscal consolidation with high growth: A policy simulation model for India

In this paper a fiscal consolidation program for India has been presented based on a policy simulation model that enables us to examine the macroeconomic implications of alternative fiscal strategies, given certain assumptions about other macro policy choices and relevant exogenous factors. The model is then used to estimate the outcomes resulting from a possible strategy of fiscal consolidation in the base case. The exercise shows that it is possible to have fiscal consolidation while at the same time maintaining high GDP growth of around 8% or so. The strategy is to gradually bring down the revenue deficit to zero by 2014–15, while allowing a combined fiscal deficit for centre plus states of about 6% of GDP. This provides the space for substantial government capital expenditure, which translates to a significant public investment program. This in turn leads to high overall investment directly and indirectly, via the crowding in effect on private investment, which drives the high GDP growth. The exercise has also tested the robustness of this strategy under two alternative scenarios of higher and lower advanced country growth compared to the base case.     

Government expenditure composition and fiscal policy spillovers in small open economies within a monetary union

We examine the implications of government expenditure that is complementary to private consumption, and government investment that can improve the productivity of private capital, in a global DSGE model. We show that government investment can improve an economy’s external competitiveness and stimulate private investment. If governments can finance this investment by reducing consumption that is not complementary to private consumption, then this is ex-ante budget-neutral, provides a small, but persistent stimulus without a deterioration in competitiveness, and leads to lower debt in the medium run. We also examine the cross-border transmission channels of government expenditure shocks in a monetary union when government consumption is complementary to private and public investment is productive. While both assumptions enhance cross-border spillovers, a direct import content is required to generate spillovers similar to those found in the empirical literature.     

Discretionary fiscal policy and economic activity in Greece

This paper investigates the effects of discretionary fiscal policy changes on economic activity and its subcomponents in Greece in the period 2000–2011. Changes in government spending and net taxes have Keynesian effects. An increase in government consumption has the most pronounced positive effects on output growth, private consumption and non-residential investment, while it reduces residential investment. Cuts in the public investment programme crowd in private investment, but are associated negatively with the net exports ratio. Both indirect and direct tax hikes lower private consumption, private investment and output growth. However, higher direct taxes by lowering disposable income they reduce import demand, thus, improving the trade balance.     

Human capital investment and debt constraints

When young individuals face binding debt constraints, their human capital investments will be insufficiently financed by private creditors. If generations overlap, then a well-designed fiscal policy may be able to improve human capital investments by replacing missing capital markets with an intergenerational transfer scheme. The optimal (balanced budget) fiscal policy in this context entails the joint provision of an education subsidy for the young and a pension program for the old, financed with a tax on those in their peak earning years. We demonstrate, however, that the desirability of such a cradle-to-grave policy depends crucially on the assumption of an exogenous debt constraint. If debt constraints arise endogenously for reasons of limited commitment, then the optimal (balanced budget) fiscal policy looks radically different. Furthermore, we find that cradle-to-grave type policy interventions may actually lead to lower levels of human capital investment as altered default incentives induce private creditors to contract the supply of student loans by an amount greater than the subsidy. In some cases, the constrained-optimal policy entails zero intervention. These results highlight the importance of taking seriously the reasons for why debt constraints exist.     

Financing government investment and its implications for public capital: A small open economy perspective

Expenditure reductions played a key role in many small open economies during fiscal consolidation, with large declines in public investment. This led to a reduction in public capital stock and affected the competitiveness of these economies. After the sovereign debt crisis, the governments that consider increasing investment to replenish the public capital stock have limited fiscal space and have to avoid external imbalances. We show that using budget-neutral investment spending can generate long-term benefits of higher public capital stock while at the same time limiting negative consequences for the public finances and the trade balance. The best way of financing government investment, which preserves fiscal and trade balances, and increases welfare, is by reducing other government spending. The second-best is financing investment with value-added tax. Financing with debt worsens fiscal and trade balances, while using distortionary labour taxes reduces labour supply, increases wage costs and worsens the trade deficit in the short run.     

Public debt accumulation and fiscal consolidation

In this study, we analyse the relationship between interest rates on government bonds (GB) and the fiscal consolidation rule by using an overlapping generation model with endogenous and stochastic growth settings. Our key findings are summarized as follows. First, contrary to conventional view, we find that interest rates on GB may decline as public debt accumulates relative to private capital. Second, the simulation reveals that the economy may exhibit discrete changes with divergent interest rates, implying that the observed trend of relatively low interest rates on GB with public debt accumulation may not continue indefinitely in the future. Third, fiscal consolidation rule plays a key role in determining equilibrium interest rates.
