Multipliers of expected vs. unexpected fiscal shocks: The case of Korea

We compare the multipliers of expected and unexpected fiscal shocks. In doing so, we consider that the future path of fiscal policy is anticipated to some degree, and incorporate this characteristic into a news approach. We build a standard small open economy New-Keynesian DSGE model with a fully specified fiscal policy structure, and examine the Korean economy as an example of a small open emerging economy. We find that the present-value multiplier of the government consumption news shock in Korea is smaller than that of a corresponding surprise shock of the same magnitude, apart from the initial couple of years in the case of the output multiplier, and is consistently smaller in the cases of the consumption and investment multipliers. The present-value output multiplier of the government consumption news shock starts from about 0.72 and declines continuously to reach 0.16 after 40 years.

A program for algebraic and qualitative comparative statics and stability analysis

This paper presents a computer program designed by the author which determines algebraically and qualitatively both short- and long-run comparative statics multipliers for standard linear or linearized economic models. When the model is dynamic, i.e., when it involves linear of linearized differential equations, the program also provides the algebraic expressions and the qualitative signs for the coefficients of the characteristic polynomial.     

Is fiscal expansion more effective in a financial crisis?

After the Great Recession, the Keynesian expansionary policy has been regarded as an effective measure, especially under imperfect financial market conditions. Among literature related to fiscal policy in financial crises, Fernández-Villaverde (2010) suggests that the fiscal policy multiplier increases in a financial crisis through the Fisher effect. However, we should note that the author simply compared the multiplier computed in the standard new Keynesian dynamic stochastic general equilibrium (DSGE) with that in the DSGE with financial accelerator settings. As the financial accelerator is considered effective during both financial crises and normal financial conditions, the author’s comparison should be considered insignificant for showing a greater multiplier in the financial crisis. In this study, to make the exact comparison, we first estimate parameters regarding the Fisher effect under each regime separately and then compute and compare the estimated fiscal multipliers using these 2 estimates in the same DSGE model. Using Japanese financial data that provide enough observations under the good and bad regimes of financial conditions, we find that fiscal multipliers are smaller in the bad regime than in the good regime.     

资本市场中企业价值评估方法

国际上通行的企业估价方法主要有三种:现金流量贴现法、相对比较乘数法和期权估价法。我国“新兴加转轨”的国情决定了相对比较乘数法是应用最多、适用性较强的方法;现金流量贴现法虽然代表了我国企业评估方法未来的发展方向,但它暂时还难以适应我国的现状;期权估价法在我国目前的适用性较低,却有着较大的发展空间,值得投资者充分重视。     

Effects of changes in outputs and in prices on the economic system: an input–output analysis using the spectral theory of nonnegative matrices

The (physical) output adjustment model and the price adjustment model are presented. By the two models we quantitatively analyze the influences of alterations of one sectoral (physical) gross output and of one sectoral price on another sectoral (physical) gross output and on another sectoral price, respectively. Hence, a basic nature of the Ghosh inverse and a fundamental character of the monetary Leontief inverse are obtained. The proposition that a matrix of intermediate output (input) coefficients alters if the vector of output (price) adjustment coefficients is nontrivial holds, if and only if this matrix is C-irreducible. It is impossible that (i) the adaptation of output system causes all sectoral final output rates (or input multipliers) either to rise or to fall collectively, or (ii) an adjustment of price system causes all sectoral value-added rates (or output multipliers) either to increase or to decrease jointly. However, maybe (i) a change of output system enables some sectoral final output rates (or input multipliers) to rise (fall) and all others to be constant, and (ii) an alteration of price system enables some sectoral value-added rates (or output multipliers) to increase (decrease) and all others to be fixed, whose necessary and sufficient condition is that the matrix of intermediate output (or input) coefficients has at least one non-final (or non-initial) class. The proposition that the vector of final output rates (or input multipliers) changes if the vector of output adjustment coefficients is nontrivial is true, if and only if the matrix of intermediate output coefficients has only one final class. The proposition that the vector of value-added rates (or output multipliers) alters if the vector of price adjustment coefficients is nontrivial holds, if and only if the matrix of intermediate input coefficients has only one initial class. The necessary and sufficient conditions and the matching economic explanations for possibility and uniqueness of the economic adjustment that enables (i) all sectors to have a uniform final output rate (or input multiplier), and (ii) all sectors to have the same value-added rate (or output multiplier) are respectively given. I would like to thank an anonymous referee for helpful comments and suggestions.     

IS GOVERNMENT SPENDING STIMULATIVE?

This paper develops and implements a neoclassical model of fiscal policy. The paper's main empirical hypothesis is that government non-military investment spending is more expansionary than is either government consumption or military investment. The paper utilizes annual data to support the hypothesis. It finds that output "multipliers" for government non-military investment significantly exceed unity while multipliers for government consumption and military investment lie below unity. The paper also finds that public sector deficits—both actual and cyclically adjusted—contain minor explanatory power for output when one controls for the effects of non-military investment.     

Investor Rationality and House Price Bubbles: Berlin and the German Reunification

Abstract. We analyze the behavior of investors in the Berlin rental apartment house market over the years 1980–2004. Using constant‐quality multipliers (price–rent ratios), we reject the hypothesis that multipliers in the market were set in a rational manner. Supported by narrative evidence, we conjecture that investors misjudged the economic effects of the German reunification. To examine this, we employ a stylized structural economic model and analyze the effects of shocks on rational multipliers. It seems that investors confused the reunification with a permanent supply side shock to the economy. By basing their investment decisions on this misjudgement, investors behaved irrationally, but in a very uncertain and unprecedented environment.     

Fiscal Austerity and the Multiplier in Times of Crisis

To address concerns about the sustainability of public debt, most industrialized countries shifted towards fiscal austerity after 2010. A popular concern is that austerity is self‐defeating, because fiscal multipliers can be large. Specifically, a number of recent studies find that multipliers tend to be large during financial crises and/or if monetary policy is constrained by the zero lower bound. However, public debt crises tend to have an offsetting effect by making multipliers smaller than during normal times. Consequently, while austerity is no cure for all, it is unlikely to be literally self‐defeating when sovereign risk is high.     

So alike,yet so different: Comparing fiscal multipliers across EU members and candidates

We estimate, using a Panel Vector Autoregressive approach and data from 2001Q1 to 2017Q1, the fiscal multipliers of the European Union (EU) members and candidates. These countries are grouped according to their stages of integration: original members, new Eurozone members, and candidates for the Eurozone and the EU itself. For each group, we assess the impact of a positive spending shock (expansionary) or a positive tax shock (contractionary) on GDP. Our findings suggest that: (i) rising government spending increases GDP in both the EU and Eurozone candidates (Keynesian multipliers), but slightly decreases it in the Eurozone members (non-Keynesian multipliers); (ii) higher taxes are associated with mixed results in terms of GDP dynamics - both increases and decreases in terms of GDP are found - in the four country groups (suggesting the presence of Keynesian and non-Keynesian multipliers). Overall, these outcomes indicate that spending multipliers are, compared to tax multipliers, more sensitive to European Union or Eurozone membership.     

On the size of government spending multipliers in Europe

This article compares the size of government spending multipliers in Europe by applying a panel structural vector autoregression analysis on 11 eurozone and 8 non-eurozone countries using quarterly data from 1991Q1 to 2012Q4. We find that (i) spending multipliers are smaller in eurozone compared to non-eurozone countries, (ii) across the euro area the impact of government spending on GDP has been higher before than after the introduction of the euro, (iii) spending multipliers are larger in the eurozone periphery than in the core countries and (iv) since the beginning of the recent financial crisis, spending multipliers have become larger both for eurozone and for non-eurozone countries. We relate these results to an emerging theoretical literature linking the size of fiscal multipliers to the monetary policy stance. We also discuss the implications of our findings for the effectiveness of fiscal policy in Europe.     

Money creation and credit multipliers ∗

The standard objections against the quantity theory of money, based on the instability of the velocity of money, are insufficient to discard this long-held monetary theory. The principal criticism of the theory rests on the determination of the money supply. The supply of money is a dependent variable, not an independent one. The demand for credit determines the quantity of money, or at the very least bankers and borrowers share the responsibility. Causality is thus reversed. It is necessary to abandon the concept of money multipliers, which are relics of the quantity theory of money. Bankers can, if they so desirerespond without limitto demands for credit. They are not tied by a fixed amount of pre-existing assets. The goal of the article is to outline an explanation of these statements and provide a vision of monetary theory that is different from that usually taught.     

Fiscal multipliers in good times and bad times

This paper estimates the magnitudes of government spending and tax multipliers within a regime-switching framework for the U.S. economy during the period 1949:1–2006:4. Our results show that the magnitudes of spending multipliers are larger during periods of low economic activity, while the magnitudes of tax multipliers are larger during periods of high economic activity. We also show that the magnitudes of fiscal multipliers got smaller for episodes of low growth, while they got larger for episodes of high growth in the post 1980 period. Analyzing the effects of government spending and taxes on consumption and investment spending indicates that the magnitude of the effects of fiscal shocks on consumption and investment is very small.     

Small Fiscal Multipliers Do Not Justify Austerity: A Macroeconomic Accounting Analysis of Public Debt-to-GDP Dynamics

In the aftermath of the Great Recession, a debate about the size of fiscal multipliers emerged. Whatever the estimation approach, fiscal multipliers assumed for projections are the result of extrapolations from time-series data. In this article, I take a different perspective by answering the following question: Is it really necessary to know the value of fiscal multipliers to make sensible policy decisions?     

Determinants of fiscal multipliers revisited

We generalize a simple New Keynesian model and show that a flattening of the Phillips curve reduces the size of fiscal multipliers at the zero lower bound (ZLB) on the nominal interest rate. The factors behind the flatting are consistent with micro- and macroeconomic empirical evidence: it is a result of, not a higher level of price rigidity, but an increase in the degree of strategic complementarity in price-setting – invoked by the assumption of a specific instead of an economy-wide labour market, and decreasing instead of constant-returns-to-scale. In normal times, the efficacy of fiscal policy and resulting multipliers tends to be small because negative wealth effects crowd out consumption, and because monetary policy endogenously reacts to fiscally-driven increases in inflation and output by raising rates, offsetting part of the stimulus. In times of a binding ZLB and a fixed nominal rate, an increase in (expected) inflation instead lowers the real rate, leading to larger fiscal multipliers. Conditional on being in a ZLB-environment, under a flatter Phillips curve, increases in expected inflation are lower, so that fiscal multipliers at the ZLB tend to be lower. Finally, we also discuss the role of solution methods in determining the size of fiscal multipliers.     

ON FISCAL MULTIPLIERS: ESTIMATES FROM A MEDIUM SCALE DSGE MODEL

This article contributes to the debate on fiscal multipliers, in the context of an estimated dynamic stochastic general equilibrium model, featuring a rich fiscal policy block and a transmission mechanism for government spending shocks. I find the multiplier for government spending to be 1.07, which is largest on impact. The multipliers for labor and capital tax on impact are 0.13 and 0.34, respectively. The effects of tax cuts take time to build and exceed stimulative effects of spending by 12–20 quarters. I carry out counterfactual exercises to show how alternative financing methods and expected monetary policy have consequences for the size of fiscal multipliers.     

What drives the short-run costs of fiscal consolidation? Evidence from OECD countries

We investigate how the short-term effects of fiscal consolidation on output and employment vary with the state of the business cycle, monetary policy, public debt, the current account, and private credit. By examining the response of a large number of variables, we are also able to shed light on the transmission channels of fiscal policy. Our main finding is that short-term output multipliers are below unity, even in states in which multipliers are expected to be larger (eg when the output gap is negative or monetary policy tight). Key offsetting factors that reduce the size of multipliers and explain differences across states are the extent to which the external sector improves and monetary policy eases.     

Economic and environmental efficiency using a social accounting matrix

This paper aims to show the utility of the so-called Social Accounting Matrix and Environmental Accounts (SAMEA) for economic and environmental efficiency analysis. The article uses the SAMEA for Spain in 2000, applied to water resources and greenhouse gas emissions. This matrix is used as a central core of a multisectorial model of economic and environmental performance, and it calculates the denominated “domestics SAMEA multipliers” and their decomposition into characteristic, direct, indirect and induced effects. These multipliers show some evaluation of economic and environmental efficiency. Also, we present an application of these multipliers that demonstrates that there is no causal interrelation between those sectors with higher economic backward linkages and those with higher environmental deterioration backward linkages.     

Government Expenditure in India: Composition and Multipliers

We estimate fiscal multipliers for total, capital (capex), and revenue (revex) Indian government expenditure using a two variable Structural Vector Auto-Regression (SVAR). Our quarterly data allows us to estimate both short- and long-run multipliers. We then extend and re-estimate the model including supply shocks and the monetary policy response sequentially and together and re-estimate the multipliers. The long-run capex multiplier remains much larger than the corresponding revex multiplier in all the estimations. The short run impact multiplier is the highest for revex, but does not rise after the first quarter. The capex peak multiplier in the 2nd quarter is 1.6–1.9 times larger. The cumulative multiplier is also the highest for capex, 2.4–6.5 times the size of the revex multiplier. Capex also reduces inflation more over the long-term. Despite this, capex shows greater volatility since it is more vulnerable to discretionary cuts. Monetary accommodation of capex and revex is allowed to differ. It varies in the absence/presence of supply shocks. The combination of a direct cut in capex and monetary tightening in response to a supply shock reduces the capex multiplier. The results are consistent with an elastic long-run aggregate supply. Disaggregated evaluation of spending policy, therefore, gives useful insights.

     

THE SIZE OF FISCAL MULTIPLIERS AND THE STANCE OF MONETARY POLICY IN DEVELOPING ECONOMIES

Implementing fiscal programs during monetary policy expansions seems to improve significantly their economic stimulus. We find this result by estimating the effect of government consumption shocks on gross domestic product (GDP) using a panel of 23 developing economies. Our goal is to better understand the reasons for the low fiscal multipliers found in the literature by performing estimations for alternative exchange rate regimes, business‐cycle phases, and monetary policy stances. In addition, we perform counterfactual simulations to analyze the possible gains from fiscal‐monetary policy coordination. Our results also show lower multipliers in developing economies with flexible regimes, especially during economic slowdowns. (JEL E62, E63, F32)
