To react or not? Technology shocks, fiscal policy and welfare in the EU-3

This paper develops a dynamic stochastic general equilibrium (DSGE) model to examine the quantitative macroeconomic implications of counter-cyclical fiscal policy for France, Germany and the UK. The model incorporates real wage rigidity and consumption habits, as the particular market failures justifying policy intervention. We subject the model to productivity shocks and allow policy instruments to react to the output gap and the debt-to-output ratio. A welfare analysis reveals that the most effective instrument-target combination is to use public consumption to stabilize the output gap. Moreover, welfare gains from counter-cyclical fiscal policy are much stronger in the presence of wage rigidities compared with consumption habits. Finally, since active policy and automatic stabilizers are substitutes, it is possible that relatively undistorted economies may be in need of countercyclical fiscal action due to inadequate automatic stabilizers.     

How does population aging affect the effectiveness of fiscal stimulus over the business cycle?

What is the impact of population aging on the effectiveness of fiscal stimulus over the business cycle? We address this question by estimating state-dependent fiscal multipliers in member countries of the Organisation for Economic Co-operation and Development (OECD). A government spending shock is identified as a forecast error of government spending and its output effect is estimated by using the local projection method. We find that there is no effect of population aging on output effects of fiscal spending shocks in expansionary times, whereas in recessions the output effects of fiscal spending shocks are weakened as population ages. This result points to important policy implications in that population aging would call for a larger fiscal stimulus to support aggregate demand during recession. Thus, this requires a larger fiscal space to allow for a wider swing of the fiscal position without creating concerns for fiscal sustainability.     

Increasing Public Expenditure: Wagner's Law in OECD Countries

Abstract. The paper proposes a panel cointegration analysis of the joint development of government expenditure and economic growth in 23 Organization Economic Cooperation and Development countries. The empirical evidence provides indication of a structural positive correlation between public spending and per‐capita gross domestic product (GDP), which is consistent with the so‐called Wagner's law. A long‐run elasticity larger than 1 suggests a more than proportional increase of government expenditure with respect to economic activity. In addition, according to the spirit of the law, we found that the correlation is usually higher in countries with lower per‐capita GDP, suggesting that the catching‐up period is characterized by a stronger development of government activities with respect to economies in a more advanced state of development.     

Fiscal policy and private consumption in industrial and developing countries

This paper empirically studies the effects of fiscal policy shocks on private consumption. Further, it investigates if the initial financing needs of the government or previous fiscal deficits affect that relationship. We use yearly data between 1970 and 2000 for 40 countries, of which 19 are industrialized and 21 are developing countries. In general, the estimation results seem to indicate that government consumption shocks have Keynesian effects for both industrial and developing countries. In the case of tax shocks, the evidence is mixed. Furthermore, there is no evidence that favors the hypothesis of expansionary fiscal consolidations.     

Fiscal shocks and their consequences

This paper investigates the response of hours worked and real wages to fiscal policy shocks in the post-World-War II US. We identify these shocks with exogenous changes in military purchases and argue that they lead to a persistent increase in government purchases and tax rates on capital and labor income, and a persistent rise in aggregate hours worked as well as declines in real wages. The shocks are also associated with short lived rises in aggregate investment and small movements in private consumption. We describe and implement a methodology for assessing whether standard neoclassical models can account for the consequences of a fiscal policy shock. Simple versions of the neoclassical model can account for the qualitative effects of a fiscal shock. Once we allow for habit formation and investment adjustment costs, the model can also account reasonably well for the quantitative effects of a fiscal shock.     

Military spending and the black market premium in developing countries

Researchers who have been concerned with the economic implications of military spending have mostly concentrated on its impact on economic growth, corruption, real exchange rate and inflation. In this paper we investigate the impact of military spending on black market premium, an area that has not been tackled so far. After adding a measure of military spending to a well established model of black market premium form the literature, we estimate the model by pooling annual data over the 1985 – 1998 period across 61 developing countries. Results from five panel specifications provide considerable evidence that higher military spending leads to higher black market premium.     

Fiscal counter-cyclical rules and their conflicting implications for growth and welfare

The paper examines the choices for fiscal stabilisation policy that maximise aggregate welfare and long-run growth. This is done in the context of a stochastic dynamic general equilibrium model where premeditated learning provides the engine of human capital accumulation and growth, and technology shocks provide the impulse source of fluctuations. Contrary to existing conventional wisdom, the results indicate a conflict between the two policy objectives: the choice of no stabilisation, associated with maximum growth, is also associated with minimum welfare. Welfare maximisation requires a full counter-cyclical response to the occurrence of business cycles. I am grateful to three anonymous referees for their constructive comments and suggestions. I would also like to thank Theodore Palivos, Keith Blackburn, seminar participants in Athens and Thessaloniki, and participants at the 2006 conference on Theories and Methods in Macroeconomics (Toulouse) and the 2007 conference of the Society for the Advancement of Economic Theory (Kos), for their valuables comments and suggestions on earlier drafts.

我国积极财政政策在总需求管理过程中起到了重要作用.通过判断我国财政政策工具和财政政策规模与经济周期波动之间的关联,描述结构VAR模型中财政政策的作用和反馈过程,我们发现我国积极财政政策操作过程中体现出了一定程度的相机选择性和对经济周期阶段的依赖性,这意味着在我国经济增长已经出现"软扩张"的经济周期态势下,应当适当调整财政政策的期限结构和政策工具,加强货币政策的组合作用,继续保持积极财政政策对国内产出的作用方向.     

Public external debt,informality and production efficiency in developing countries

This paper proposes an alternative approach to investigate the non-linear effect of external debt on growth. In the theoretical part, we develop an endogenous growth model with formal and informal sectors to analyse the effect of the public external debt on the production efficiency. We show that an increase of the public external debt share increases the production efficiency through a positive externality effect. However, it generates an opposite effect via the reduction of the formal sector’s size in favour of a less efficient informal sector. The resultant effect becomes negative beyond an optimal level. Besides, we show that a large stock of public external debt reduces the production efficiency when it leads to a tight fiscal policy which reduces the formal sector size. Empirically, using a stochastic frontier technique with unobserved heterogeneity, for a panel of 27 developing countries for the period of 1970–2005, we confirm that the turning point associated to the effect of the share external public debt is apparent at 84%.     

Transparency and central bank losses in developing countries

Recent evidence shows central banks suffering from losses in some developing countries. This is a surprise to economists and policymakers. At the same time, these banks are asked to conduct monetary policy within a more transparent framework. Therefore, this paper seeks to answer the following question: Would more transparency in developing countries suffering from central bank losses be beneficial?This paper shows that the cost constraints of conducting monetary policy, central bank losses, in both transparency and opacity alike is significant and affects positively the error of the private sector in expected inflation rate and the output gap. In a country suffering from central bank losses, the expected benefits of transparency and the existence of cost constraint move in two opposite directions. As a result, it is unwise for developing countries suffering from central bank losses to focus on transparency. Priority should be given to fixing monetary policy and to developing financial markets.     

On the importance of institutions and forms of organisation in Piero Sraffa's economics: the case of business cycles,money, and economic policy

Abstract

This paper is based on an investigation of the Sraffa Archives and tries to characterise Piero Sraffa's approach to business cycles and economic policy. It includes two parts. The first part of the paper shows the importance of economic institutions and social conventions in Sraffa's contribution to economics and their relation with social conflicts. The second part of the paper shows how this importance permits to understand better business cycles and economic policy but also indirectly contributes to a re-interpretation of Sraffa's contribution to economics.     

Public consumption composition in a growing economy

This paper explores the role of the composition of public consumption within a three sector R&D growth model. A competitive industry supplies a homogeneous good and a monopolistic sector manufactures a composite commodity differentiated in many varieties, whose size can be increased through investment in R&D. We investigate the effects of changes in the level and in the composition of public consumption on the steady state and on the economy’s transitional dynamics. By varying the aggregate composition of demand, the government can effectively move resources away from the traditional industry to foster innovation. Welfare effects are also evaluated. We show that the composition of government consumption affects the entire time path of utility.     

Government size, composition, volatility and economic growth

This paper analyses the effects in terms of size and volatility of government revenue and spending on growth in OECD and EU countries. The results of the paper suggest that both variables are detrimental to growth. In particular, looking more closely at the effect of each component of government revenue and spending, the results point out that i) indirect taxes (size and volatility); ii) social contributions (size and volatility); iii) government consumption (size and volatility); iv) subsidies (size); and v) government investment (volatility) have a sizeable, negative and statistically significant effect on growth.     

Engel's law, Petty's law, and agglomeration

This paper presents a model of structural change and agglomeration. A decline in transportation costs, by enhancing consumers’ purchasing power, leads to Engel's law of the demand shift from agricultural to non-agricultural goods. At the same time, the decline in transportation costs, by enlarging the extent of the market for non-agricultural goods, induces Petty's law of the labor reallocation from agriculture to non-agricultural activities. These structural transformations weaken dispersion forces given by farmers tied to the land, whereas they strengthen agglomeration forces generated by footloose non-agricultural workers. Thus, a substantial decline in transportation costs gives rise to agglomeration of non-agricultural activities.     

Monetary policy shocks and productivity measures in the G-7 countries

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification: E5, F4Correspondence to: Charles L.

An assessment of telecommunications reform in developing countries

This paper analyzes the impact of policy reform in basic telecommunications on sectoral performance using a new panel data set for 86 developing countries across Africa, Asia, the Middle East, Latin America and the Caribbean over the period 1985 to 1999. We address three questions. First, what impact do specific policy changes—relating to ownership and competition—have on sectoral performance? Second, how is the impact of change in any one policy affected by the implementation of the other, and by the overall regulatory framework? Third, does the sequence in which reforms are implemented affect performance? We find that both privatization and competition lead to significant improvements in performance. But a comprehensive reform program, involving both policies and the support of an independent regulator, produced the largest gains: an 8 percent higher level of mainlines and a 21 percent higher level of labor productivity compared to years of partial and no reform. Interestingly, the sequence of reform matters: mainline penetration is lower if competition is introduced after privatization, rather than at the same time.     

Budget balances in OECD countries: what makes them change?

Fiscal balances have deteriorated quickly in recent years, bringing back to the foreground the question what factors explain such sharp changes. This paper takes a broad perspective at the issue regarding countries included, the range of potential explanatory variables, and the time-span covered. The empirical analysis shows that changes in budget balances are affected by debt growth, macroeconomic developments and political factors. In particular, we find that the run-up to EMU induced additional consolidation in Europe and that budget balances deteriorate markedly in election years. Asset prices also affect budgets, but the impact remains limited in normal times.      

GDP dynamics and unemployment changes in developed and developing countries

We design a new specification of Okun’s model that takes the following features into account: estimation of the relation in first differences, the possible lagged effect of GDP dynamics on unemployment changes, the persistence of unemployment rate dynamics, the possible different values of Okun coefficients under recession (with respect to periods of increases in GDP), the existence of cross-country institutional and structural differences (i.e. country-specific Okun coefficients), the additional effect on unemployment caused by large adverse shocks such as financial crises.

A distinctive feature of this article is its consideration of a large set of countries for which we find differentiated Okun coefficients. Moreover, we focus in particular on the distinction between developed and developing countries, and on the additional impact of financial crises. From an econometric point of view, the model developed belongs in the family of linear mixed-effects models. The estimation method uses an expectation-maximization (EM) algorithm. Our results confirm the general validity of ‘Okun’s law’; they show the Okun coefficient differences between high- and low-income countries; and they evidence an additional impact of some types of financial crisis on the unemployment dynamics of developed economies.     

Consumption,wealth and business cycles in Germany

This paper studies the long-run relationship between consumption, asset wealth and income—the consumption–wealth ratio—based on German data from 1980 to 2003. We find that departures from this long-run relationship mainly predict adjustments in income. The German consumption–wealth ratio also contains considerable forecasting power for a range of business cycle indicators, including the unemployment rate. This finding is in contrast to earlier studies for some of the Anglo-Saxon economies that have shown that the consumption–wealth ratio reverts to its long-run mean mainly through subsequent adjustments in asset prices. While the German consumption wealth ratio contains little information about future changes in German asset prices, we report that the U.S. consumption–wealth ratio has considerable forecasting power for the German stock market. One explanation of these findings is that in Germany—due to structural differences in the financial and pension systems—the share of publicly traded equity in aggregate household wealth is much smaller than in the Anglo-Saxon countries. We discuss the implications of our results for the measurement of a potential wealth effect on consumption.
