Taxes and firm investment

We investigate the firm-level investment response to unanticipated narrative shocks to average personal and corporate tax rates using a universal micro dataset of publicly-traded U.S. firms for the post-1976 period. Using local projections, we show that: (i) corporate tax shocks have significant effects on investment while personal tax shocks do not; (ii) corporate income tax responses are negative overall, and this result is driven by smaller firms who face larger borrowing constraints, especially when the accompanying monetary policy is contractionary or output gap is slack; (iii) there is some evidence of positive personal income tax responses during monetary contractions by dividend-paying firms, which is consistent with the recent literature.     

SHOULD WE CARE ABOUT THE COMPOSITION OF TAX‐BASED STIMULUS PACKAGES?

We investigate the effects of tax policy shocks on the U.S. economy over the 1972:3–2008:4 period within a structural vector autoregressive (SVAR) framework. Disaggregating tax shocks suggests that the positive output multipliers documented for total taxes by the previous literature are present only for indirect tax innovations. We also show that both labor and corporate taxes have similar effects on output, with labor tax multipliers being slightly larger in magnitude. The positive and negative responses of inflation following respectively corporate and labor tax shocks imply that former shocks work through aggregate supply, whereas the latter work predominantly through aggregate demand.

What are the effects of fiscal policy on asset markets?

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy.     

Tax multipliers and monetary policy: Evidence from a threshold model

Romer and Romer (2010) use the narrative record to generate a time series of exogenous shocks to fiscal policy. They report a tax multiplier of 3.0. We extend their analysis and allow for nonlinearities between their shocks and the effects on output by estimating a threshold regression model. Using Hansen’s (1997) procedure, we find the best fitting threshold is changes in the federal fund rate with a delay of two quarters. Moreover, we find that the tax multiplier is approximately 4.3 if accompanied by an accommodative monetary policy and approximately 1.2 under tight monetary policy.     

Exogenous tax changes and interest rates: testing for Ricardian equivalence using an efficient markets model

This article tests the Ricardian theory (i.e., Barro 1974) using Mishkin’s (1981, 1982) efficient markets model of interest rates. Employing Romer and Romer’s (2010) measure exogenous tax changes, I am able to test whether the U.S. bond market reacts in a Keynesian or Ricardian manner to exogenous tax policy changes. This helps avoid the endogeneity problems associated with measuring the interest rate effects of deficits and provides a cleaner test of the pure Ricardian thought experiment. I find a significant negative relationship between tax changes and interest rates which is inconsistent with the Ricardian model and support the Keynesian crowding out framework.     

Fiscal policy and national saving

This paper uses structural vector autoregressions along with structural measures of fiscal policy to measure the dynamic impact of fiscal policy shocks on the output gap and national saving. Positive shocks to government purchases and negative shocks to real net taxes are found to increase the output gap. Positive shocks to the government's structural surplus increases national saving although the effects are small. Positive shocks to government purchases are found to substantially reduce national saving. Negative shocks to real net tax revenues as a share of potential GDP have a small negative impact on national saving.     

CREDIT,HOUSING COLLATERAL,AND CONSUMPTION: EVIDENCE FROM JAPAN,THE U.K., AND THE U.S.

The consumption behavior of U.K., U.S., and Japanese households is examined and compared using a modern Ando‐Modigliani style consumption function. The models incorporate income growth expectations, income uncertainty, housing collateral, and other credit effects. These models therefore capture important parts of the financial accelerator. The evidence is that credit availability for U.K. and U.S., but not Japanese, households has undergone large shifts since 1980. The average consumption‐to‐income ratio rose in the U.K. and U.S. as mortgage down‐payment constraints eased and as the collateral role of housing wealth was enhanced by financial innovations, such as home equity loans. The estimated housing collateral effect is similar in the U.S. and U.K. In Japan, land prices (which proxy house prices) continue to negatively impact consumer spending. There are negative real interest rate effects on consumption in the U.K. and U.S. and positive effects in Japan. Overall, this implies important differences in the transmission of monetary and credit shocks in Japan versus the U.S., U.K., and other credit‐liberalized economies.     

The consequences of an unknown debt target

Several proposals to reduce U.S. debt reveal large differences in their targets. We examine how an unknown debt target affects economic activity using a real business cycle model in which Bayesian households learn about a state-dependent debt target in an endogenous tax rule. Recent papers use stochastic volatility shocks to study fiscal uncertainty. In our setup, the fiscal rule is time-varying due to unknown changes in the debt target. Households infer the current debt target from a noisy tax rule and jointly estimate the transition probabilities. Three key findings emerge from our analysis: (1) limited information about the debt target amplifies the effect of tax shocks through changes in expected tax rates; (2) the welfare losses are an order of magnitude larger when both the debt target state and transition matrix are unknown than when only the debt target state is unknown to households; (3) an unknown debt target likely reduced the stimulative effect of the ARRA and uncertainty about the sunset provision in the Bush tax cuts may have slowed the recovery and led to welfare losses.     

Using Romer and Romer's new measure of monetary policy shocks to identify the AD and AS shocks

This article re-examines the series of (exogenous) Federal Funds Rate (FFR) shocks created by Romer and Romer (2004) for the period 1969:01–1996:12. We hypothesize that if Romer and Romer have constructed a reasonable set of monetary policy shocks, then including them in a small Vector Autoregression (VAR) should help to identify other structural shocks that affected the United States economy during their sample period. Using a sample period of 1971:01–1996:12 we are easily able to identify both an Aggregate Demand (AD) shock and an Aggregate Supply (AS) shock without imposing any sign or long-run restrictions. We present historical decompositions that allow us to compare the relative importance of these shocks with that of the exogenous monetary policy shocks in explaining output fluctuations during the 1973–1975, 1980–1984 and 1990–1991 business cycle episodes.     

Fiscal shocks, output dynamics and macroeconomic stability: an empirical assessment for Austria (1983–2002)

We investigate the dynamic effects of discretionary fiscal policy in Austria over the period 1983:1 to 2002:4. A structural vector autoregressive (VAR) analysis, using the identification strategy suggested by Blanchard and Perotti (2002, Q J Econ 117(4):1329–1368), suggests that tax shocks have a negative effect on output, consumption, and investment. Spending shocks have a positive effect but are crowded out to a large extent after a few years. We then estimate ARCH models for output growth and inflation with the fiscal shocks included as explanatory variable in the variance equation. In line with recent cross-country studies there is evidence for a destabilizing role of discretionary fiscal policy.     

Inequality-growth nexus under progressive income taxation

Within heterogeneous-household extensions of Romer’s (1986) one-sector representative agent model of endogenous growth, this paper finds that changes made to the U.S. statutory income tax in the past decades account for a substantial portion of the following stylized facts: (i) U.S. income inequality significantly deteriorates since the mid-1980s; (ii) the inequality-growth nexus displays a positive slope before and after the implementation of the Tax Reform Act of 1986 (TRA-86); and (iii) the slope of the inequality-growth nexus sharply declines between the pre- and post-TRA-86-reform periods, indicating less deterioration in real GDP per capita growth when pursuing a more equal income distribution after 1986. In addition to income inequality, the responses of several other measurements of inequality to changes in the tax code parameters are also explored.     

Growth Effects of Capital Income Taxes: How Much Does Endogenous Innovation Matter?

The paper compares the way economies with exogenous and endogenous innovation respond to capital income taxes. If innovation is exogenous, tax cuts increase saving. If innovation is endogenous, tax cuts increase innovation as well. Faster innovation raises capital productivity and calls forth still more saving. A larger capital stock lowers the discount rate, increases the present value of monopoly profit and calls for faster innovation. How large a difference endogenous innovation might make is an open question. We calculate numerical solutions of a model including features of the U.S. tax code that affect incentives to innovate. The results suggest that models with exogenous innovation substantially underestimate long–run effects of capital income taxes.     

Fiscal multipliers in the Eurozone: an SVAR analysis

We compute the value of fiscal multipliers (for government primary expenditure, Income and wealth taxes and for Production and import taxes) in the Eurozone countries since the creation of the currency union (2000Q1-2016Q4), in order to understand how the values can vary according to the public debt level, the pace of economic growth, and the output gap. Imposing quarterly fiscal shocks, the results showed that government expenditure had a positive effect on output, with an annual accumulated multiplier of 0.44, whereas tax multipliers presented negative signs: the Income and wealth and the Production and import taxes stood at ?0.11 and ?0.55, respectively. Furthermore, the spending multiplier showed a higher value for countries with lower levels of public debt, during recessions, and in countries with negative output gaps. On the other hand, tax shocks seemed to be recessive in highly indebted countries and those facing positive output gaps.     

Determinants of land value volatility in the U.S. Corn Belt

ABSTRACT

Understanding land value volatility and its reaction to exogenous shocks helps land owners, investors, and lenders assess risk. Land value volatility, the variance of the unpredictable component of land value growth rates, is modelled for each of the Corn Belt states in the U.S. using EGARCH. A pooled VAR system is then estimated to capture the interactions between land value determinants and land value volatility. The variables of the pooled VAR are split into negative and positive vectors to allow for asymmetric impacts. Impulse response functions are mapped. All states exhibit land value volatility clustering. Inflation, cash rent and population growth rates granger cause land value volatility. Land value volatility responses to negative shocks are greater than those to positive shocks. Lenders and investors should expect greater swings in land values after negative shocks to land value growth rates, but not an overreaction of land values from shocks to cash rent growth rates. Positive shocks to changes in interest rates increases land value volatility, but unexpected shocks to population growth rates do not have statistically significant impact on land value volatility.     

Public investment and budgetary consolidation in Portugal

In this paper we find that public investment in durable goods has a positive effect on long-term economic performance in Portugal. We also find that these positive effects are not strong enough for public investment to pay for itself in the form of future tax revenues. Therefore, cuts in public investment in durable goods, although costly in terms of long-term economic performance seem to be an effective way of alleviating pressure on the public budget. It is important to note, however, that this general result contrasts sharply with the evidence found in this paper for public investment in equipment, a small component of public investment in durable goods, as well as with evidence elsewhere for public investment in transportation infrastructures. For these, the effects on output are strong enough for public investment to pay for itself. Therefore, cuts in these two types of public investment, would have negative long-term economic effects as well as negative long-term budgetary effects. Clearly, not all public investment is created equal. We would like to thank the editor as well as two anonymous referees for unusually useful comments and suggestions.

Stochastic Growth and Factor Income Risk

Abstract. This paper examines the effects of aggregate factor income risk in a tractable version of the stochastic Romer endogenous growth model. Labor supply is endogenous. The presence of labor income risk unambiguously increases savings and growth due to precautionary motives. Households not only underaccumulate but also work less along the balanced growth path of the competitive economy when compared with the Pareto-efficient allocation. The paper also discusses distributive disturbances for the case of inelastic labor supply. Here, growth effects are negative for empirically plausible correlations of the underlying shocks.     

Economic policy uncertainty and real output: evidence from the G7 countries

We use economic policy uncertainty index, and impulse response based test to assess the impact of economic policy-related uncertainty on real economic activity. We use monthly data, over the period from 1985:1 to 2015:3, and impulse response functions to investigate how the economies of the G7 countries respond to positive and negative economic policy uncertainty shocks of different magnitudes. We find that economic policy uncertainty is countercyclical, that the effects of uncertainty shocks increase with size and that the responses of real output to positive and negative economic policy uncertainty shocks are country specific. Our research is important for policymaking and in favour of policies that remove economic uncertainty and its negative effects on the economy. We argue that some control over yellow journalism, a transparent tax system and a set of predictable fiscal and monetary policies can minimize the social costs of economic policy uncertainty.     

Fiscal multipliers in a structural VEC model with mixed normal errors

This paper estimates the effects of fiscal policy shocks on GDP in the United States with a vector error correction (VEC) model in which shocks are identified by exploiting the non-normal distribution of the model residuals. Unlike previous research, the model used here takes into account cointegation between the variables, and applies a data driven method to identify fiscal policy shocks. The approach also allows statistical testing of previous identification strategies, which may help discriminate between them and hence also explain differences between various fiscal multiplier estimates. Our results show that a deficit financed government spending shock has a weak negative effect on output, whereas a tax increase to finance government spending has a positive impact on GDP.     

Foreign output and price shocks and macroeconomic activity in Korea

This paper examines the effects of foreign output and price shocks on output and the price level in Korea. The framework is a nine variable VAR model which includes output, price level, interest rate, real exchange rate, money supply, government expenditures, government debt, and foreign output and price variables. Foreign output and price effects are evaluated through computation of variance decompositions and impulse response functions. The variance decompositions indicate significant effects of foreign output on domestic output and significant effects of foreign prices on domestic output and the price level. The impulse response functions indicate positive short-run effects of foreign output on domestic output but insignificant effects on the price level while foreign price shocks have significant negative effects on output and significant positive effects on the price level for approximately two years. The results indicate the importance of including foreign shock variables when modeling the Korean economy.     

Self-selection and Pareto efficient taxation

This paper analyses the set of Pareto efficient tax structures. The formulation of the problem as one of self-selection not only shows more clearly the similarity between this problem and a number of other problems (such as the optimal pricing of a monopolist) which have recently been the subject of extensive research, but also allows the derivation of a number of new results. We establish (i) under fairly weak conditions, randomization of tax structures is desirable; (ii) if different individuals are not perfect substitutes for one another in production, then the general equilibrium effects—until now largely ignored in the literature—of changes in the tax structure may be dominant in determining the optimal tax structure; in particular if the relative wage of high ability and low ability individuals depends on the relative supplies of labor, the optimal tax structure entails a negative marginal tax rate on the high ability individuals, and a positive marginal tax rate on the low ability individuals (the marnitude of which depends on the elasticity of substitution); (iii) if individuals differ in their preferences, Pareto efficient taxation may entail negative marginal tax rates for high incomes; while (iv) if wage income is stochastic, the marginal tax rate at the upper end may be 100%.Our analysis thus makes clear that the main qualitative properties of the optimal tax structure to which earlier studies called attention are not robust to these attempts to make the theory more realistic.
