Stochastic and structural fiscal policy in a monetary stationary economy

In the framework of a monetary asset pricing model which is simple enough to generate closed form formulae for equilibrium price functions the interactions between output, fiscal policy, and asset markets is investigated. With money yielding liquidity services in the exchange process real stock prices are negatively correlated with anticipated (stochastic) fiscal policy changes, while the impact of unanticipated (structural) fiscal policy on the stock market depends qualitatively on the ‘business cycle’ of the economy. It is shown that the monetary character of the economy, more precisely the role of money in the exchange process, is critical for the relationship between fiscal policy and real share prices. Moreover, while contingent fiscal policy measures may be successful in stabilizing the real interest rate on money they are incapable of achieving a stable term structure of the real rate on stocks. In contrast, uncontingently higher public expenditures generally promote the volatility of the real rates on financial assets.     

Unemployment and the shadow economy

Current research links the shadow economy (SE) and the unemployment rate either indirectly or by means of a preliminary estimate. This article establishes and empirically implements a methodology for estimating the size of the SE as a direct function of the tax and unemployment rates. This link is found to be extremely relevant in countries with high unemployment rates (such as Greece and Spain) and less relevant in countries with moderate unemployment rates (such as Germany and Italy). Unemployment’s contribution to the SE is shown to be significant, especially in the years following the economic downturn of 2008. The calculation of the variance and distribution of these estimates is another significant contribution. The common criticism that SE estimates are unreliable is addressed by calculating the variance and the distribution of the estimates, and the large size of the SE in Greece and Spain is once again confirmed.     

Monetary–fiscal policy interactions and fiscal stimulus

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.     

Distortionary fiscal policy and monetary policy goals

We reconsider the role of an inflation conservative central banker in a setting with distortionary taxation. To do so, we assume monetary and fiscal policy are decided by independent authorities that do not abide to past commitments. If the two authorities make policy decisions simultaneously, inflation conservatism causes fiscal overspending. But if fiscal policy is determined before monetary policy, inflation conservatism imposes fiscal discipline. These results clarify that in our setting the value of inflation conservatism depends crucially on the timing of policy decisions.     

Entry and fiscal policy effectiveness in a small open economy within a Monetary Union

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).

Ramsey fiscal policy and endogenous growth

This paper examines the effects of fiscal policies on capital accumulation and economic performance in a simple endogenous growth model with elastic labor supply by focusing on the implementability of a competitive equilibrium with productive public spending and distortionary taxation. Given a feasible exogenous fiscal policy, productive public spending can, at first, lead to positive short-run and long-run growth in the unique competitive equilibrium. However, although strictly positive growth is possible in the short run, a Ramsey policy with productive public spending does not implement positive capital accumulation in the long run. Also, the local indeterminacy of Ramsey allocations, in conjunction with the global multiplicity, arises as an implementable competitive equilibrium with Ramsey policies: namely, a continuum of transitional dynamics and multiple balanced growth paths.

The changing nature of the OECD shadow economy

Traditionally, the presence of the shadow economy (SE) has been associated, mainly and positively, with taxation. Recently, some authors have suggested that the SE may be also linked to the institutional setting (efficiency of the bureaucracy, regulations, corruption, etc.) so that just two stable equilibria are possible. In the “good” one, there is a small hidden sector, large fiscal revenues and honest/appreciated institutions. The other, “bad”, equilibrium is the opposite. Unlike the traditional approach, therefore, the recent literature argues that the tax burden and SE can be negatively correlated. Examining the links between these variables in relatively uncorrupt systems, this paper reconciles the two views. Theoretically, it claims that many different good equilibria can emerge whereby SE and its determinants are linked in complex and different ways. For instance, taxation and SE can go hand-in-hand, even taking into account the institutional framework. Empirical evidence for OECD countries supports both the model and the changing nature of the SE.     

Deficits,full employment and the use of fiscal policy

According to orthodox economic wisdom, fiscal policy is incapable of solving the unemployment problem because government deficits crowd out consumer spending, business investment and net exports. This paper argues that neither theoretical nor empirical support exists for such claims. In addition, misplaced and mistaken fears about government deficits have kept national governments from employing fiscal policy when necessary. By abandoning fiscal policy, national governments have contributed to rising unemployment in the developed world.     

‘Crowding out’ and the effectiveness of fiscal policy

‘Crowding out’ of private economic activity by public economic activity is a multidimensional concept. A taxonomy is proposed: the degree of crowding out, the time horizon considered, direct and indirect crowding out constitute the four main categories. The latter two each have many subcategories. With direct crowding out government economic activity directly enters as an agrument into structural private behavioural relationships. Indirect crowding out refers to crowding out in the reduced form of the model without there being any direct crowding out at the level of the structural private behavioural relationships. A small full employment model is used to analyse the implications of various forms of direct crowding out for the effectiveness of fiscal policy.

Rationality, political economy, and fiscal responsibility: wrestling with tragedy on the fiscal commons

The continuing budget deficits and accumulating public debt that commonly plagues western democracies reflects a clash between two rationalities regarding human governance: one of private property and its conventions and one of common property and its procedural framework. Democratic budgeting creates a form of fiscal commons whose governance is subject to the tragic outcomes depicted by Garret Hardin (in Science 162:1243?C1248, 1968). To be sure, tragedy can be avoided as Elinor Ostrom (1990) explains, but only to the extent that the fiscal commons is governed in a manner consonant with Antonio De Viti de Marco??s (1936) model of the cooperative state. While the tragedy of the commons that results from this tectonic clash is an inherent feature of democratic political economy, that tragedy can nonetheless be limited through reasserting the conventions and institutions of a constitution of liberty.     

Government debt and optimal monetary and fiscal policy

How do different levels of government debt affect the optimal conduct of monetary and fiscal policies? And what do these optimal policies imply for the evolution of government debt over time? To provide an answer, this paper studies a standard monetary policy model with nominal rigidities and monopolistic competition and adds to it a fiscal authority that issues nominal non-state contingent debt, levies distortionary labor income taxes and determines the level of public goods provision. Higher government debt levels make it optimal to reduce public spending, so as to dampen the adverse incentive effects of distortionary taxes, but also strongly influence the optimal stabilization response following technology shocks. In particular, higher debt levels give rise to larger risks to the fiscal budget and to tax rates. This makes it optimal to reduce government debt over time. The optimal speed of debt reduction is missed when using first-order approximations to optimal policies, but is shown to be quantitatively significant in a second-order approximation, especially when technology movements are largely unpredictable in nature.     

Factor mobility and fiscal policy in the EU: policy issues and analytical approaches

Increased integration of labour and capital markets creates significant challenges for the welfare states of modern Europe. Taxation of capital and labour that finances extensive programmes of cash and in-kind redistribution creates incentives for capital owners and workers to locate in regions where they obtain favourable fiscal treatment. Competition among countries for mobile resources constrains their ability to alter the distribution of income and may lead to reductions in the size and scope of redistributive policies. Mobility of labour and capital is imperfect, however. Recent trends indicate that labour and capital are neither perfectly mobile nor perfectly immobile, but rather adjust gradually to market conditions and economic policies. This paper presents an explicitly dynamic analysis showing that governments can achieve some redistribution when it is costly for factors of production to relocate. As the costs of factor mobility fall, however, the effectiveness of redistributive policies is more limited, and governments have weaker incentives to pursue them. Liberalized immigration policies, EU enlargement, and other steps that promote integration of the factors markets of Western Europe with those of surrounding regions thus present a challenge to policy-makers if they also wish to maintain fiscal systems with extensive redistribution.     

Optimal fiscal policy, uncertainty, and growth

This paper analyzes the macroeconomic effects of fiscal policy in a stochastic endogenous growth model. Due to externalities in human capital accumulation, the market allocation is inefficient, thereby justifying government intervention. The uncertainty stemming from technological disturbances affects the growth rate, which can be explained by precautionary motives of risk averse agents. Fiscal policy means consist of a consumption tax, investment subsidies, and bonds. We obtain counter-acting growth effects of investment subsidies, which are differentiated with respect to deterministic and stochastic capital income components. The policy implications from the deterministic model are substantially extended in the stochastic context. A general rule for a welfare maximizing policy is derived, which is represented by a continuum of alternative tax-transfer-schemes. We discuss three benchmark cases, which crucially differ with respect to their implications regarding the size of the government expenditure share.     

Cross-country evidence on the distributional impact of fiscal policy

This article provides new evidence on the distributional effects of fiscal policy using data on a panel of OECD economies over the last four decades. We study how four measures of income inequality and poverty respond to several stock and flow variables accounting for fiscal actions. We find that increases in government debt and expenditure promote a less unequal distribution of income. We detect a significant distributional impact of education and social spending as well as of government consumption expenditure. We also investigate potential redistributive implications of large fiscal expansion and consolidation episodes finding no evidence of additional effects beyond those associated with conventional fiscal variables.

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.
