News - or foresight - about future economic fundamentals can create rational expectations equilibria with non-fundamental representations that pose substantial challenges to econometric efforts to recover the structural shocks to which economic agents react. Using tax policies as a leading example of foresight, simple theory makes transparent the economic behavior and information structures that generate non-fundamental equilibria. Econometric analyses that fail to model foresight will obtain biased estimates of output multipliers for taxes; biases are quantitatively important when two canonical theoretical models are taken as data generating processes. Both the nature of equilibria and the inferences about the effects of anticipated tax changes hinge critically on hypothesized information flows. Different methods for extracting or hypothesizing the information flows are discussed and shown to be alternative techniques for resolving a non-uniqueness problem endemic to moving average representations.

Using the post-WWII data of U.S. federal corporate income tax changes, within a Smooth Transition VAR, this paper finds that the output effect of capital income tax cuts is government debt-dependent: it is less expansionary when debt is high than when it is low. To explore the mechanisms that can drive this fiscal state-dependent tax effect, the paper uses a DSGE model with regime-switching fiscal policy and finds that a capital income tax cut is stimulative to the extent that it is unlikely to result in a future fiscal adjustment. As government debt increases to a sufficiently high level, the probability of future fiscal adjustments starts rising, and the expansionary effects of a capital income tax cut can diminish substantially, whether the expected adjustments are through a policy reversal or a consumption tax increase. Also, a capital income tax cut need not always have large revenue feedback effects as suggested in the literature.

Fiscal stimulus was widely advocated during the global crisis, a period characterized by monetary policy constrained by the effective lower bound (ELB) in many countries, in part because of expected positive spillovers. Standard New Keynesian models predict the cross-border transmission of fiscal shocks is stronger when monetary policy is constrained in recipients. However, the empirical evidence is scarce. This paper bridges this gap by looking at the impact of fiscal shocks in systemic (source) economies on output and demand components in a large group of (recipient) countries, under different monetary policy conditions. Empirical results are compared to simulations with a state-of-the-art estimated open-economy New Keynesian model. Our results corroborate model predictions, finding larger spillovers when recipients are at the ELB, driven by stronger responses of investment and consumption relative to normal times

Are fiscal spillovers today as large as they were during the global financial crisis? How do they depend on economic and policy conditions? This note informs the debate on the cross-border impact of fiscal policy on economic activity, shedding light on the magnitude and the factors affecting transmission, such as the fiscal instruments used, cyclical positions, monetary policy conditions, and exchange rate regimes. The note assesses spillovers from five major advanced economies (France, Germany, Japan, United Kingdom, United States) on 55 advanced and emerging market economies that represent 85 percent of global output, looking at government-spending and tax revenue shocks during expansion and consolidation episodes. It finds that fiscal spillovers are economically significant in the presence of slack and/or accommodative monetary policy—and considerably smaller otherwise, which suggests that spillovers are large when domestic multipliers are also large. It also finds that spillovers from government-spending shocks are larger and more persistent than those from tax shocks and that transmission may be stronger among countries with fixed exchange rates. The evidence suggests that although spillovers from fiscal policies in the current environment may not be as large as they were during the crisis, they may still be important under certain economic circumstances.

This book explores the role of national fiscal policies in a selected group of Euro-area countries under the European Economic and Monetary Union (EMU). In particular, the authors characterize the response of output to fiscal consolidations and expansions in the small Euro-area open economies affected by high public and private debt. It is shown that the macroeconomic outcome of fiscal shocks is strongly related to debt levels. The Euro-area countries included in the investigation are Greece, Ireland, Italy, the Netherlands, Spain, and Portugal, over the sample period 1999–2016, i.e., the EMU period. The main econometric tools used in this research are structural vector autoregressive (VAR) models, including panel VAR models. The available literature relating to the subject is also fully reviewed. A further closely investigated topic is the potential spillover effects of German fiscal policies on the selected small Euro-area economies. Moreover, in the perspective of the evolution of the Euro Area towards a full Monetary and Fiscal Union, the authors study the effects of area-wide government spending shocks on aggregate output and other macroeconomic variables during the EMU period. The closing chapter of the book considers evidence on the consequences of austerity policies for European labour markets during recent years.

This paper provides new evidence on the existence and magnitude of the “twin deficits” in developing economies. It finds that a one percent of GDP unanticipated increase in the government budget balance improves, on average, the current account balance by 0.8 percentage point of GDP. This effect is substantially larger than that obtained using standard measures of fiscal impulse, such as the cyclically-adjusted budget balance. The results point to heterogeneity across countries and over time. The effect tends to be larger: (i) during recessions; in countries (ii) that are more open to trade; (iii) that have less flexible exchange rate regimes; and (iv) with lower initial public debt-to-GDP ratios.

How do policy communications on future f iscal targets af fect market expectations and beliefs about the future conduct of f iscal policy? In this paper, we develop indicators of f iscal credibility that quantify the degree to which policy announcements anchor expectations, based on the deviation of private expectations f rom official targets, for 41 countries. We find that policy announcements partly re-anchor expectations and that f iscal rules and strong fiscal institutions, as well as a good policy track record, contribute to magnifying this effect, thereby improving fiscal credibility. Conversely, empirical analysis suggests that markets reward credibility with more favorable sovereign financing conditions.

Would population aging affect the effectiveness of fiscal stimulus? Despite the renewed focus on population aging, there are few empirical studies on the output effects of fiscal policy in aging economies. Our study fills this gap by analyzing this issue in OECD countries. We find that, as population ages, the output effects of fiscal spending shocks are weakened. We also find that, while high-debt countries generally face weaker fiscal multipliers, high-debt aging economies face even weaker multipliers. These results point to important policy implications: population aging would call for a larger fiscal stimulus to support aggregate demand during recession and thus require larger fiscal space to allow a wider swing of the fiscal position without creating concerns for fiscal sustainability. Our analysis also suggests that policy measures to promote labor supply could help increase the output effect of fiscal stimulus in aging economies.

Unanticipated changes in tax policy are likely to have different macroeconomic effects compared to anticipated changes due to several mechanisms, including fiscal foresight and policy uncertainty. It is therefore important to understand what drives such policy surprises. We explore the nature of unanticipated tax policy changes by focusing on a political economy determinant of those events, namely the timing of elections. Using monthly data for 22 advanced economies and emerging markets over the period 1990-2018, we show that implementation lags tend to be significantly longer for tax policy change announcements that are made during the pre-election periods, thereby leading to a lower likelihood of “tax news shocks”. We also find that implementation lags become much shorter for tax policy changes that are announced in the aftermath of elections, generating more frequent tax news shocks. This pattern remains similar for different tax measures or types of taxes. The findings are robust to a number of checks, including alternative definitions of tax news shocks, or to controlling for various economic and institutional factors.
