Asset price volatility and government revenue

This paper investigates the effect of commercial, residential property and equity price volatility on the variability of cyclically adjusted government revenue. We find significant evidence that asset price volatility increases the variability of government revenue. A 1% increase in equity price volatility increases government revenue variability by 0.37–0.44%. An increase in residential property price volatility increases revenue volatility by about 0.15–0.22%, whereas this effect diminishes to 0.11% in case of commercial property price. This evidence reflects the automatic increase of government revenue variability due to asset price movements and supports arguments in favour of adjusting fiscal variables for both business cycle and asset price changes. However, we also find evidence that equity price variability increases revenue variability even when government revenue is adjusted for both economic and asset price cycles, indicating the presence of more complicated dynamics between fiscal variables and asset price changes.     

Fiscal policy and the Spanish business cycle

A main result of the RBC literature is that technological factors drive fluctuations of macroeconomic variables around its long-run growth path. Nevertheless, it has been shown that in some countries fluctuations of some fiscal variables may explain some of the business cycle fluctuations. In this paper I show that a result of this sort can be obtained for the Spanish economy. Specifically, I use both technological and fiscal shocks to reproduce the observed volatility of hours of work to output, hours of work to average productivity, and the negative correlation between hours and average productivity.     

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.     

Intergovernmental transfers and procyclical public spending

This paper tests the predictions that (i) sub-central government expenditures are procyclical and (ii) sub-central government expenditures are likely to be more procyclical than central government spending. The predictions are based on the importance of ‘voracity effects’ and on the proposition that they are systematically more pervasive if spending is financed by intergovernmental transfers. Evidence from 23 OECD countries between 1995 and 2006 indicates that sub-central government spending is more procyclical than central government expenditure.     

Jointly optimal monetary and fiscal policy rules under liquidity constraints

We study the welfare properties of an economy where both monetary and fiscal policies follow simple rules, and where a subset of agents is liquidity constrained. The welfare benefits of optimizing the fiscal rule are far larger than those of optimizing the monetary rule. The optimized fiscal rule implements strong automatic stabilizers that primarily stabilize the income of liquidity-constrained agents, rather than output. Transfers targeted to liquidity-constrained agents are the preferred fiscal instrument. The optimized monetary rule exhibits super-inertia and a weak inflation response. Optimized simple rules perform as well as the optimal policy under the timeless perspective.     

The dynamics of inequality and social security in general equilibrium

This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period Overlapping-Generation model to capture the intra-generational redistributive effect of social security transfers. Political decision-making is represented by a probabilistic voting à la Lindbeck and Weibull (1987). We analytically characterize the Markov perfect equilibrium, in which social security tax rates are shown to be increasing in wealth inequality. A dynamic interaction between inequality and social security leads to larger social security programs. In a model calibrated to the U.S. economy, the dynamic interaction is shown to be quantitatively important: It accounts for more than half of the social security growth in the dynamics. We also perform some normative analysis, showing that the politico-economic equilibrium outcomes can be fundamentally different from the Ramsey allocation.     

Using inflation to erode the US public debt

Projections indicate the US Federal debt held by the public may exceed 70–100% of GDP within 10 years. In many respects, the temptation to inflate away some of this debt burden is similar to that at the end of World War II. In 1946, the debt ratio was 108.6%. Inflation reduced this ratio by more than a third within a decade. Yet there are some important differences – shorter debt maturities today reduce the temptation to inflate, while the larger share of debt held by foreigners increases it. This paper lays out an analytical framework for determining the impact of a large nominal debt overhang on the temptation to inflate. It suggests that when economic growth is stalled, the US debt overhang may induce an increase in inflation of about 5% for several years that could significantly reduce the debt ratio.     

Spurious regressions driven by excessive volatility

This paper shows that the excessive volatility results in spurious regressions. The spuriousness can be driven by persistency in the error variances unlike the conventional spurious regressions that are generated by the persistency in the level of regression errors.     

Optimal nonlinear income taxation with productive government expenditure

This paper develops an endogenous growth model with a production externality and nonlinear income taxation, and uses it to examine how the fiscal authority devises its nonlinear tax structure from the viewpoint of welfare maximization. It is found that, in the Barro (1990) model, Pareto optimality can be achieved if both policy instruments for the tax scalar and the extent of the tax progressivity/regressivity are set optimally.     

Redistribution and the marginal cost of public funds

Discussions of the marginal cost of public funds with distortionary taxation are often cast in the framework of a one-consumer economy, while the main justification of distortionary taxes is that they are needed for redistribution. This paper analyzes the issue in a model with heterogeneous consumers and a linear income tax, focusing on the tradeoff between labour market distortions and the redistribution from high-wage to low-wage workers. In an optimal tax system the MCF will be the same for all sources of funds and under certain assumptions less than one. Without optimality the MCF will in general differ between different sources of finance.     

Forward-looking monetary policy and anticipated shocks to inflation

This paper extends a standard New Keynesian model to describe the effects of anticipated shocks to inflation and forward-looking monetary policy. Using the data generated from this modified model suggests that overlooking these two factors in the standard Cholesky structural vector autoregressive identification scheme will generate a price puzzle. Furthermore, this paper demonstrates that failing to account for these two factors may result in significant estimates of two other explanations of the price puzzle—the cost channel of transmission of monetary policy and indeterminacy due to violation of the Taylor principle—even though neither features in the data generating process.     

A further investigation of unemployment persistence in European transition economies

This paper analyses the dynamics of the unemployment rate in the eight countries from Central and Eastern Europe which joined the EU in 2004. Unit root tests allowing for nonlinearities and structural changes suggest that the unemployment rate is not stationary in most of the sample countries. Tests allowing for fractional integration, however, reveal that shocks are highly persistent, implying a slow rate of convergence to the natural rate of unemployment. The unemployment rate is least persistent in Hungary and Slovenia, more persistent in the Czech Republic, Slovakia and the Baltic States and extremely persistent in Poland. The degree of persistence appears to reflect the different levels of economic and institutional development in the countries and possibly also the role of the government.     

Noisy information, interest rate shocks and the Great Moderation

In this paper we evaluate the hypothesis that the Great Moderation is partly the result of a less activist monetary policy. We simulate a New Keynesian model in which the central bank can only observe a noisy estimate of the output gap and find that the less pronounced reaction of the Federal Reserve to output gap fluctuations since 1979 can account for a substantial part of the reduction in the standard deviation of GDP associated with the Great Moderation. Our simulations are consistent with the empirically documented smaller magnitude and impact of interest rate shocks since the early 1980s.     

Cross-country causes and consequences of the crisis: An update

We update [13] and [Rose and Spiegel, 2010] and search for simple quantitative models of macroeconomic and financial indicators of the “Great Recession” of 2008–09. We use a cross-country approach and examine a number of potential causes that have been found to be successful indicators of crisis intensity by other scholars. We check a number of different indicators of crisis intensity, and a variety of different country samples. While countries with higher income and looser credit market regulation seemed to suffer worse crises, we find few clear reliable indicators in the pre-crisis data of the incidence of the Great Recession. Countries with current account surpluses seemed better insulated from slowdowns.     

Growth, income taxes and consumption aspirations

In a Barro-type economy with exogenous consumption aspirations, raising income taxes favors growth even in the presence of lump-sum taxes. Such a policy is compatible with the behavior of private consumption, income taxes and growth rates observed in actual economies.     

Growth, income distribution, and fiscal policy volatility

The relationship between income distribution and economic growth has long been an important economic research subject. Despite substantial evidence on the negative impact on long-term growth of inequality in the literature, however, there is not much consensus on the specific channels through which inequality affects growth. The empirical validity of two most prominent political economy channels - redistributive fiscal spending and taxes, and sociopolitical instability - has recently been challenged. We advance a new political economy channel for the negative link between inequality and growth, a fiscal policy volatility channel, and present strong supporting econometric evidence in a large sample of countries over the period of 1960-2000. Our finding also sheds light on another commonly observed negative relation between macroeconomic volatility and growth. We carefully address the robustness of the results in terms of data, estimation methods, outlier problem, and endogeneity problem that often plague the standard OLS (ordinary least squares) regression.     

Forecasting the volatility of S&P depositary receipts using GARCH-type models under intraday range-based and return-based proxy measures

We employ four various GARCH-type models, incorporating the skewed generalized t (SGT) errors into those returns innovations exhibiting fat-tails, leptokurtosis and skewness to forecast both volatility and value-at-risk (VaR) for Standard & Poor's Depositary Receipts (SPDRs) from 2002 to 2008. Empirical results indicate that the asymmetric EGARCH model is the most preferable according to purely statistical loss functions. However, the mean mixed error criterion suggests that the EGARCH model facilitates option buyers for improving their trading position performance, while option sellers tend to favor the IGARCH/EGARCH model at shorter/longer trading horizon. For VaR calculations, although these GARCH-type models are likely to over-predict SPDRs' volatility, they are, nevertheless, capable of providing adequate VaR forecasts. Thus, a GARCH genre of model with SGT errors remains a useful technique for measuring and managing potential losses on SPDRs under a turbulent market scenario.     

Forecasting with real-time macroeconomic data: The ragged-edge problem and revisions

Real-time macroeconomic data are typically incomplete for today and the immediate past (‘ragged edge’) and subject to revision. To enable more timely forecasts the recent missing data have to be imputed. The paper presents a state-space model that can deal with publication lags and data revisions. The framework is applied to the US leading index. We conclude that including even a simple model of data revisions improves the accuracy of the imputations and that the univariate imputation method in levels adopted by The Conference Board can be improved upon.     

Monetary business cycle accounting

This paper investigates the quantitative importance of various types of distortions for inflation and nominal interest rate dynamics by extending business cycle accounting to monetary models. Representing various classes of real and nominal distortions as ‘wedges’ in standard equilibrium conditions allows a quantitative assessment of those distortions. Decomposing the data into movements due to these wedges shows that distortions generating movements in TFP and wedges in equilibrium conditions for asset markets are essential. In contrast, wedges capturing the effects of sticky prices play less important role. These results are robust to alternative implementations of the accounting method.
