A Repeated Interactions Model of Tax Competition

Models of tax competition usually assume a single-period framework. This paper sets up a repeated interactions model of tax competition and establishes conditions under which fiscal policy harmonization can result from repeated interactions between governments. It is shown that fiscal policy harmonization cannot prevail when regional asymmetries are too strong. In such a case, the only way to achieve fiscal policy harmonization is to set up a central fiscal authority.     

Fiscal Policy and Equitable Growth

This paper continues the study of optimal fiscal policy in a growing economy by exploring a case in which the government simultaneously provides three main categories of expenditures with distortionary tax finance: public production services, public consumption services, and state-contingent redistributive transfers. The paper shows that in a general-equilibrium model with given exogenous fiscal policy, a nonmonotonic relation exists between the suboptimal long-run growth rate in a competitive economy and distortionary tax rates. When fiscal policy is endogenously chosen at a social optimum, the relation between the rate of growth and tax rates is always negative. These two properties suggest that an alternative set of government policy instruments affects the response of private sector investment to fiscal policy. Moreover, the different properties of exogenous and endogenous fiscal policy theoretically account for the difference in the relation between economic growth and fiscal policy in empirical studies.     

Capital mobility and the effectiveness of fiscal policy in open economies

This paper uses a dynamic general equilibrium two-country optimizing ‘new-open economy macroeconomics’ model to analyze the consequences of international capital mobility for the effectiveness of fiscal policy. Conventional wisdom suggests that higher capital mobility diminishes the effectiveness of fiscal policy. The model laid out in this paper provides an example that a higher degree of capital mobility can also increase the effectiveness of fiscal policy. This tends to be the case if the stance of monetary policy can be described by means of a simple monetary policy rule.     

Fiscal Multiplier in Microstates: Evidence from the Caribbean

The global financial crisis and the attendant Great Recession of 2007–2009 have spawned a full-scale re-examination on the effectiveness of fiscal policy throughout the world. While this has led to a plethora of analyses in developed countries, the same abundance of the work has not been evident for developing counties. This paper uses time-series analysis to examine the multiplier impact of fiscal policy on growth and other macroeconomic variables in the case of four Caribbean states. Although these countries have similar degrees of openness, they differ in debt burdens and economic structures, thus providing a natural laboratory for this investigation. We concluded that fiscal multipliers among the sample countries are quite low and that the contemporaneous fiscal stance appears to be pro-cyclical.     

Optimal fiscal policy in a world liquidity trap

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.

International interdependencies in fiscal stabilization policies

Trade links imply that business cycle fluctuations are transmitted among trade partners. To the extent that fiscal policy can mitigate business cycle fluctuations international interdependencies in stabilization policies arise. We analyse in a two country general equilibrium model the role of fiscal policy in mitigating risk or providing implicit insurance in the presence of capital market imperfections and adjustment failures (rigid wages). It is shown that there is a welfare case for an active stabilization policy, and that it is larger in the presence of adjustment failures (rigid wages). Non-cooperative policy decisions imply inefficiencies in fiscal stabilization policies, which in the case of flexible wages may imply too much stabilization, whereas stabilization is always insufficient in the case of rigid wages.     

Macroeconomic Stabilization in the EMU: Rules Versus Institutions

This paper investigates the macroeconomic implications of different regimes of international fiscal coordination and monetary‐fiscal cooperation in a monetary union with independent fiscal authorities, that act strategically vis‐à‐vis a common central bank. In the presence of other policy goals than cyclical stabilization, such as interest rate smoothing and fiscal stability, we show that coordination among national fiscal authorities can reduce output and inflation volatility relative to the non‐cooperative setting in specific circumstances, as in case of demand disturbances, while turning potentially counterproductive otherwise. The adverse effects of union‐wide coordinated fiscal measures can be attenuated in a regime of global coordination, namely, when a centralized fiscal stabilization is coordinated with the common monetary policy as well.     

Inter-Governmental Fiscal Relations: The Facilitator of Fiscal Decentralization

The decentralization of fiscal authority to lower level jurisdictions contributes to the efficient delivery of public services, but conflicts with national objectives. This paper argues that the system of fiscal relations, including both the grant structure and institutions for policy coordination, are necessary for achieving the full benefits of fiscal decentralization while preserving national efficiency and equity objectives. The case for decentralization is recounted, along with the ways it can impinge upon efficiency and equity in the national economy. These adverse effects can be mitigated by appropriate fiscal transfers, both equalizing and conditional, and suitable measures of policy harmonization.     

Central bank communication on fiscal policy

The issue of central bank communication on fiscal policy has so far received very little attention in the literature. This article aims to shed light on the determinants of central bank communication on fiscal policy by analysing the intensity of central banks’ fiscal communication for five central banks (the Federal Reserve, the ECB, the Bank of Japan, the Bank of England and the Swedish Riksbank) over the period 1999–2011. The ECB communicates intensively on fiscal policies, in a normative way. The other central banks emphasise foreign fiscal developments, fiscal policy as input to forecasts, or the use of government debt instruments in monetary policy operations. The empirical analysis indicates that the financial crisis has overall increased the intensity of central bank communication on fiscal policy. The evolution of the government deficit ratio is a driver of the intensity of fiscal communication in the euro area, the US and Japan, and for Sweden since the start of the crisis, while in the UK its intensity is related to government debt developments as of the start of the crisis.     

National numerical fiscal rules: Not complied with,but still effective?

This paper investigates the effects of (non-)compliance with national numerical fiscal rules on fiscal policy in 11 EU member states with 23 fiscal rules in place from 1994 to 2012. Introducing a new dataset of legal texts constituting the fiscal rules, allows a joint empirical analysis of different types and designs of numerical fiscal rules. In various empirical exercises the change in the difference between the exact variable constrained by the fiscal rule and its numerical limit is analysed. Statistics show that countries comply with their fiscal rules only in about 50% of the years. Nevertheless, various econometric exercises demonstrate that the introduction of fiscal rules does significantly change the behaviour of fiscal policy. If countries do not comply with their fiscal rule in the year or forecast before, there is a strong downward tendency of the constrained variable towards the numerical limit. The results show that fiscal rules act as kind of a benchmark for policy makers and the public, and even though they might be complied with only in half of the years, they still tilt fiscal policy towards the numerical limit in times of non-compliance.     

How fiscal policy affects housing market dynamics: Evidence from Spain

This paper studies how the announcements of fiscal law changes affect the real estate market, focusing on the case of Spain. An announcement of a future fiscal law change gives the opportunity to buyers to advance or delay purchases to maximize fiscal benefits. In particular, we study announcements and their posterior effects about the mortgage tax laws in 1998, 2010, 2011, and 2013 plus the VAT law in 2012. The paper is based on contextually rich data from 2004 through 2015 for Spain, provided by a real estate agent with a strong presence across the Spanish territory. We use two dependent variables to best capture the changes: time on market of a dwelling and the price discount of the dwelling. Simultaneity bias is avoided by considering that the degree of overpricing and atypicality affects time on market but not the selling price. The identification strategy is improved by considering the type of properties most affected by the changes versus the rest of properties, using a difference-in-difference estimation. We consider two tax policy announcements: income tax credit on dwelling purchases and VAT rate change on the purchases of new dwellings. In the case of the income tax credit, this fiscal policy affects only primary accommodations. In the case of the VAT tax rate, only new houses are affected. We show that credible fiscal policy announcements distort the housing market by temporarily decreasing dwellings’ time on market and their price discounts, to immediately and long-lastingly increase them just after the tax policy expires. There is a negative causal effect of tax policy announcements on the housing market.     

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.     

Is there a Role for an Active Fiscal Stabilization Policy?

This paper discusses the need and scope for an active fiscalstabilization policy. It is argued that the effectiveness offiscal policy as a short run stabilizer does not depend on thelong run multipliers of (balanced budget) fiscal policies. Tothe extent that activity can be affected by aggregate demandin the short run, there is a case for a fiscal stabilizationpolicy in terms of temporary variations in taxes or public consumptioncontingent on the state of the economy. The effectiveness offiscal policy is supported by empirical evidence. However, anappropriate policy intervention depends both on the nature ofthe shock and the structure of the economy. There are thus fundamentalinformation problems in pursuing discretionary fiscal policieson top of political economy concerns, and fiscal fine-tuningis not to be recommended. Automatic stabilizers do not to thesame extent suffer from these problems, but their strength isnot by design but the net result of other policy considerations.Hence, there is a need to consider the structure and size ofautomatic stabilizers.

Noisy fiscal policy

This paper investigates the macroeconomic effects of fiscal policy in a setting in which private agents receive noisy signals about future shocks to government expenditures. We show how to empirically identify the relative weight of news and noise shocks to government spending and compute the level of noise for Canada, the UK and the US. We then investigate the quantitative implications of imperfect fiscal policy information using a medium-scale DSGE model. We find that when the government seeks to implement a persistent change in expected public spending, the existence of noise (as estimated using actual data) implies a sizable difference in fiscal multipliers compared to the perfect fiscal foresight case.     

Fiscal Policy and Welfare in a Small Open Economy with Imperfect Competition

This paper considers the effects of fiscal policy in a two-sector small open economy, with unionized labour markets, and heterogeneous types of imperfect competition in the product markets. By making the marginal propensity to import endogenous, the paper shows that there is no robust or general relationship between the balanced-budget multiplier and the degree of imperfect competition. The fiscal multiplier with distortionary taxes can be positive or negative, depending on the size of the importables sector and the foreign firm's market share. The normative rule for fiscal policy depends on the size of the fiscal multiplier. An increase in economic activity is insufficient by itself to induce the government to over-supply public goods relative to the Walrasian case.     

Study on Medium- and Long-Term Fiscal Policies to Cope with Climate Change under the “Dual Carbon” Goals

Carbon peaking and carbon neutrality constitute an extensive, profound and systemic economic and social change. It is worthwhile to explore how fiscal policy, as a key institutional arrangement in the public policy system to cope with climate change, can play a fundamental and pillar role. Based on literatures, theories and empirical materials, this paper systematically explores the relationship between climate change and public finance. The fiscal impact of climate change will eventually be reflected in fiscal behavior, fiscal costs and fiscal relations, and the fiscal system has the adaptability of an “automatic stabilizer” and the proactiveness to enable the Discretionary Approaches function when facing climate change impacts. This implies such a governance logic of fiscal policy that is systematic, forward-looking and flexible in addressing climate change. In the future, it is necessary to further incorporate climate change or related environmental factors into the fiscal policy framework, target the two key aspects of mitigation and adaptation, and carry out a holistic, systematic and forward-looking reform of the existing fiscal expenditure policy, fiscal revenue policy, fiscal investment and financing policy, government budget system, government procurement policy and ecological compensation policy. While highlighting the “governance” function of fiscal policy in addressing climate change, Chinese government needs to strengthen the coordination and collaboration between fiscal policy tools and other public policies, and magnify the governance effectiveness of fiscal policy in the process of addressing climate change. This paper helps understand the positioning, role and influence of fiscal policy in the process of addressing climate change, provides a basis for better playing the fundamental and underpinning role of the modern fiscal system in the governance of ecological civilization, and presents an analytical framework for building a theoretical system of ecological fiscal governance.     

Monetary and fiscal policy interactions: Evidence from emerging European economies

This paper examines the interactions between fiscal and monetary policy for some former transition, emerging European economies over the 1995Q1–2010Q4 period by using a Markov regime-switching model. We consider the monetary policy rule proposed by Taylor (1993) and the fiscal policy rule suggested by Davig and Leeper (2007) in accounting for monetary and fiscal policy interactions. Empirical results suggest that monetary and fiscal policy rules exhibit switching properties between active and passive regimes and all countries followed both active and passive monetary policies. As for fiscal policy, the Czech Republic, Estonia, Hungary, and Slovenia seem to have alternated between active and passive fiscal regimes while fiscal policies of Poland and the Slovak Republic can be characterized by a single fiscal regime. Although the policy mix and the interactions between monetary and fiscal policy point a diverse picture in our sample countries, the monetary policy seems to be passive in all countries after 2000. This finding is consistent with the constraints imposed by European Union enlargement on monetary policy.     

What is the right balance between US monetary and fiscal policy? Explorations using simulated wavelet-based optimal tracking control

This paper uses wavelet-based optimal control to simulate fiscal and monetary strategies under different levels of policy restrictions. The model applies the maximal overlap discrete wavelet transform to US quarterly GDP data and then uses the decomposed variables to build a large 80-dimensional state-space linear-quadratic tracking model. Using a political targeting design for the frequency range weights, we simulate jointly optimal fiscal and monetary policy where: (1) both fiscal and monetary policy are dually emphasized, (2) fiscal policy is unrestricted while monetary policy is restricted to achieving a steady increase in the market interest rate, (3) only monetary policy is relatively active, while fiscal spending is restricted to achieving a target growth rate, and (4) monetary policy emphasizes short-run stabilization, while fiscal policy utilizes political cycle targeting. The results show that fiscal policy must be more aggressive when the monetary authorities are not accommodating the fiscal expansion and that the dual-emphasis policy leads to a series of interest rate increases that are balanced between a steadily increasing target and a low, fixed rate. This research is the first to construct integrated fiscal and monetary policies in an applied wavelet-based optimal control setting using US data.     

Regime changes and fiscal sustainability in Kenya

Kenya's fiscal policy landscape is characterized by primary deficit spending forcing the government to rely on debt to meet its objectives. The justification often being that as a developing economy, annual growth rates and future prospects may in the short run justify the uptake of debt to finance infrastructural development. However, given potential fiscal limits, fiscal cycles usually alternates between sustainable and unsustainable regimes and this has a bearing on long run sustainability. This study therefore sought to investigate the nature of fiscal policy regime in Kenya and the extent to which fiscal policy is sustainable in the long run taking into account periodic regime shifts. Markov switching models were used to endogenously determine fiscal policy regimes. Regime switching tests were used to test whether No-Ponzi game condition and debt stabilizing condition were met. The results established that regime switching model was suitable in explaining regime sustainable and unsustainable cycles. An investigation of fiscal policy regimes established that both sustainable and unsustainable regimes were dominant, and each lasted for an average of four years. There was evidence to imply the existence of procyclical fiscal policy in Kenya. Regime switching tests for long run sustainability suggested that the No-Ponzi game condition weakly holds in the Kenyan economy. Regime-based sensitivity analysis indicated that persistence of unsustainability regime for more than 4 years could threaten long-run fiscal sustainability.
