Distortionary Taxation, Debt, and the Price Level

This paper compares the determinacy of equilibria under exogenous interest rates in an economy with a cash constraint, in which taxation is lump-sum or distortionary. Under passive fiscal policies lump-sum taxes generate nominal indeterminacy, while with distortionary taxes indeterminacy can be real, but not purely nominal. In general, under distortionary taxation uniqueness of the equilibrium allocation depends on monetary and fiscal policy interactions through taxes, debt, and interest rates. To illustrate this principle, we consider balanced-budget policies under distortionary income taxation and show that a unique equilibrium allocation prevails if interest rates are set consistent with long-run deflation. A separate section extends the analysis to endogenous interest rates.     

Fiscal hedging with nominal assets

We analyze optimal fiscal and monetary policy in an economy with distortionary labor income taxes, nominal rigidities, nominal debt of various maturities and short-selling constraints. Optimal policy prescribes the almost exclusive use of long term debt. Such debt mitigates the distortions associated with hedging fiscal shocks by allowing the government to allocate them efficiently across states and periods.     

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.     

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.     

Disagreement about inflation and the yield curve

We show that inflation disagreement, not just expected inflation, has an impact on nominal interest rates. In contrast to expected inflation, which mainly affects the wedge between real and nominal yields, inflation disagreement affects nominal yields predominantly through its impact on the real side of the economy. We show theoretically and empirically that inflation disagreement raises real and nominal yields and their volatilities. Inflation disagreement is positively related to consumers’ cross-sectional consumption growth volatility and trading in fixed income securities. Calibrating our model to disagreement, inflation, and yields reproduces the economically significant impact of inflation disagreement on yield curves.     

Real Balance Effects,Timing, and Equilibrium Determination

By assuming that money balances at the beginning instead of at the end of the period provide transaction services, standard results on nominal and real determinacy in monetary models are overturned. The key is that predetermined real money balances can be a state variable. Whereas the determination of the absolute price level typically depends on fiscal policy under an exogenous interest setting, nominal determinacy is now achieved even when fiscal policy is Ricardian. Also, in contrast to the Taylor principle, the interest rate policy should respond passively to changes in inflation, thus ensuring nonoscillatory and locally stable equilibrium sequences.     

Optimal inflation persistence: Ramsey taxation with capital and habits

Ramsey models of fiscal and monetary policy featuring time-separable preferences and a fixed supply of capital predict highly volatile inflation with no serial correlation. In this paper, we show that an otherwise-standard Ramsey model that incorporates capital accumulation and habit persistence predicts highly persistent inflation. The result depends on increases in either the ability to smooth consumption or the preference for doing so. The effect operates through the Fisher relationship: a smoother profile of consumption implies a more persistent real interest rate, which in turn implies persistent optimal inflation. Our work complements a recent strand of the Ramsey literature based on models with nominal rigidities. In these latter models, inflation volatility is lower than in the baseline model but continues to exhibit little persistence. We quantify the effects of habit and capital on inflation persistence and also relate our findings to recent work on optimal fiscal policy with incomplete markets.     

Taxation and the Taylor principle

A nominal tax system is added to a sticky-price monetary business cycle model. When nominal interest income is taxed, the coefficient on inflation in a Taylor-type monetary policy rule must be significantly larger than one in order for the model economy to have a determinate rational-expectations equilibrium. When effective tax rates are raised by inflation, the stability of the economy's equilibrium can be adversely affected. Finally, when depreciation is treated as a charge against taxable income, an even larger weight on inflation is required in the Taylor rule in order to obtain a determinate and stable equilibrium.     

Cross‐Country Spillovers from Fiscal Consolidations

In the aftermath of the global financial crisis, many OECD countries adopted fiscal consolidation strategies to reduce their debt‐to‐GDP ratios. This paper investigates the effects of fiscal consolidation on trading partners’ growth through trade linkages. Using a measure of exogenous fiscal shocks in export markets, fiscal consolidation spillovers are found to slow down domestic growth and decrease employment. To the extent that fiscal consolidations are synchronised, fiscal policies have large spillover effects on output. Spillovers of fiscal consolidations on growth are found to be initially larger between countries belonging to currency unions, though this larger impact vanishes over the medium term. Larger spillovers of fiscal consolidation coincide with lower bilateral exports, higher bilateral imports and relative increases in unit labour costs in currency unions. Spillovers of fiscal consolidation are also found to be more detrimental to domestic growth during economic downturns in export markets.     

What Drives Fiscal Decentralisation? Further Assessing the Role of Income*

This paper investigates the determinants of fiscal decentralisation, focusing in particular on the impact of the level of income on the level of fiscal decentralisation. Various measures of fiscal decentralisation, several of them novel in this context, are employed in a cross‐country econometric model to test established and more recent hypotheses. Paying careful attention to variable measurement, model specification and sample coverage, the results suggest that there are significant relationships between fiscal decentralisation and income, as well as a range of other factors. However, these relationships may be more complicated than previously reported. For the entire large sample of countries, and for the OECD subsample, a positive relationship between income and decentralisation is found. This corroborates the results found in earlier studies. However, for the middle‐ and lower‐income nations, higher income is found to be associated with less decentralisation.     

After the death of inflation: will fiscal drag survive?

Declining inflation rates might have negative consequences for tax revenues. Phenomena such as the inflationary bracket creep in a progressive income tax system do not work any longer. With this background, the paper analyses the extent of fiscal drag for OECD countries since 1965. Some consideration of the role of money illusion and indexation in this context lays the theoretical base. A framework is presented that allows for the classification of fiscal structures with regard to the type of fiscal drag. The subsequent econometric panel analysis is performed for total and disaggregated government revenues. The results back theoretical considerations of inflation's impact on different kinds of taxes, which tends to be positive for individual income taxes and social security contributions and is negative for corporate income taxation. The paper concludes that both declining inflation and changing tax structures limit the potential for future fiscal drag.     

Public Investment in Europe: Evolution and Determinants in perspective*

We describe the evolution of public investment and public capital stocks in Europe over the past three decades. Against this background, we analyse the macroeconomic determinants of public investment, with a special focus on its long‐term trend. We find that public investment has been determined by national income, the stance of budgetary policies and fiscal sustainability considerations. Neither the cost of financing nor the fiscal rules embodied in EMU have had a systemic impact on public investment. The significant downtrend that characterises the evolution of public investment in non‐cohesion countries is chiefly determined by drawn‐out episodes of fiscal consolidation, unrelated to EMU.     

Monetary policy, taxes, and the business cycle

This paper analyzes the interaction of inflation with the tax code and its contribution to aggregate fluctuations. We find significant effects operating through the tax on realized nominal capital gains. A tax on nominal bond income magnifies these effects. Our innovation is to combine monetary policy shocks with non-indexed taxes in a model where the central bank implements policy using an interest rate rule. Monetary policy had important effects on the behavior of the business cycle before 1980 because policymakers did not exert effective control over inflation. Monetary policy reform around 1980 led to better control, and with more stable inflation, the effect of the interaction between monetary policy and the nominal capital gains tax has become negligible.     

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.     

Trend inflation, wage and price rigidities, and productivity growth

What are the steady-state implications of inflation in a general-equilibrium model with real per capita output growth and staggered nominal price and wage contracts? Surprisingly, a benchmark calibration implies an optimal inflation rate of -1.9 percent. The analysis also shows that trend inflation has important effects on the economy when combined with nominal contracts and real output growth. Steady-state output and welfare losses are quantitatively important even for low values of trend inflation. Further, nominal wage contracting is found to be quantitatively more important than nominal price contracting in generating the results. This conclusion does not arise from price dispersion per se, but from an effect of nominal output growth on the optimal markup of monopolistically competitive labour suppliers. Finally, accounting for productivity growth is found to be important for calculating the welfare costs of inflation. Indeed, the presence of 2 percent productivity growth increases the welfare costs of inflation in the benchmark specification by a factor of four relative to the no-growth case.     

Money as stock

The fiscal theory determines the price level from the value of nominal government debt as a claim to government primary surpluses, just as private stock is valued as a claim to corporate profits. Valuation equations are not constraints, so this theory does not mistreat the government's intertemporal budget constraint. I anchor the analysis in a simple cash in advance model. When money demand falls to zero, I show that the price level can still be determined by the government debt valuation equation.     

Estimating the impact of monetary policy on income inequality in China

The article estimates the impact of monetary policy on income inequality in China. The empirical time series analysis finds that a battery of monetary indicators and the change in the unemployment rate lead to increases in the Gini coefficient. But only unemployment is statistically significant. The lack of significance of the monetary indicators is robust to running different econometric models using nominal output as an alternative to unemployment. Unemployment’s impact on income inequality is robust to considering a fiscal policy proxy alongside inflation in the benchmark equation.     

The Role of Money in Monetary Policy at the Lower Bound

In light of the current low-interest-rate environment, we reconsider the merits of strict money growth targeting (MGT) relative to conventional inflation targeting (IT) and to price level targeting (PLT). We evaluate these policies in terms of social welfare through the lens of a New Keynesian model and accounting for a zero lower bound (ZLB) constraint on the nominal interest rate. Although MGT makes monetary policy vulnerable to money demand shocks, MGT contributes to achieving price level stationarity and significantly reduces the incidence and severity of the ZLB relative to both IT and PLT. Furthermore, MGT lessens the need for fiscal expansions to supplement monetary policy in fighting recessions.     

A ‘rational’ explanation for ‘irrational’ forecasts of inflation

This paper analyzes professionals' forecasts of nominal income and the inflation rate. The analysis indicates that both monetary and fiscal policy data was used efficiently to forecast income, but the monetary policy data was not used efficiently to forecast the inflation rate. Further analysis suggests that the apparent inefficient use of the monetary data results from the non-stationary money-inflation relationship predicted by rational expectations models. These models then provide an explanation for the inconsistent conclusions regarding the income forecasts and the inflation rate forecasts.
