Inequality and public debt: A positive analysis

This study extends the multi‐country, politico‐economic model of fiscal policy to incorporate wage inequality within each country. In this extended framework, we present conflict over fiscal policy within and across generations and show that a low‐inequality country realizes tight fiscal policy with low public debt accumulation, whereas a high‐inequality country experiences loose fiscal policy with high public debt. This model prediction is consistent with empirical evidence from OECD countries for the years 1980 to 2010.     

How Does Fiscal Consolidation Impact on Income Inequality?

In this paper, we assess the impact of fiscal consolidation on income inequality. Using a panel of 18 industrialized countries from 1978 to 2009, we find that income inequality significantly rises during periods of fiscal consolidation. In addition, while fiscal policy that is driven by spending cuts seems to be detrimental for income distribution, tax hikes seem to have an equalizing effect. We also show that the size of the fiscal consolidation program (in percentage of GDP) has an impact on income inequality. In particular, when consolidation plans represent a small share of GDP, the income gap widens, suggesting that the burden associated with the effort affects disproportionately households at the bottom of the income distribution. Considering the linkages between banking crises and fiscal consolidation, we find that the effect on the income gap is amplified when fiscal adjustments take place after the resolution of such financial turmoil. Similarly, fiscal consolidation programs combined with inflation are likely to increase inequality and the effects of fiscal adjustments on inequality are amplified during periods of relatively low growth. Our results also provide support for a non‐linear relationship between inequality and income and corroborate the idea that trade can promote a more equal distribution of income.     

The inequality channel of monetary transmission

We examine optimal monetary policy in the presence of inequality by introducing unskilled agents with no access to the financial system into a DSGE model with sticky prices. Our main results are: (i) a contractionary interest rate shock increases inequality, while inflation and the output gap fall; (ii) the welfare-based objective of monetary policy includes inequality stabilization; (iii) as the proportion of unskilled agents increases, welfare decreases; and (iv) under scarcity of skilled agents, monetary policy is weakened, while fiscal policy produces a more relevant impact on the economy.     

The tradeoff between growth and equity in decentralization policy: China's experience

This paper investigates the potential tradeoff between economic growth and regional equity in the design of fiscal decentralization policy in the context of China's experience. We develop a theoretical model of fiscal decentralization, where overall national economic growth and equity in the regional distribution of fiscal resources are the two objectives pursued by the central government. The model is tested using panel data for 1985–98. We find that fiscal decentralization in China has led to economic growth as well as to significant increases in regional inequality.     

收入不平等、政策偏向与最优财政再分配政策

本文构建的理论模型探讨了收入不平等、政策偏向与最优财政再分配之间的关系。模型显示:政策偏向是收入不平等与财政再分配恶性循环的决定因素。当政策偏向于穷人时,最优财政再分配系统的选择是提高税率,扩大对穷人的转移支付;当政策偏向于富人时,最优财政再分配系统的选择是降低税率,减少对穷人的转移支付。依据中国数据的实证研究发现:(1)中国收入不平等不断恶化,针对恶化的不平等而采取的财政再分配政策效果差,没能扭转不平等恶化趋势,政策偏向严重。(2)税收再分配政策偏向富人,使富人税负相对轻于穷人,居民收入不平等加剧;偏向于穷人的转移支付多为消费券(物),导致越扶越贫。为此,需要从调整所得税和转移支付政策等方面采取相关对策。     

Indexing Out of Poverty? Fiscal Drag and Benefit Erosion in Cross-National Perspective

We assess how tax-benefit policy developments in 2001–11 affected the household income distribution in seven EU countries. We use the standard microsimulation-based decomposition method, separating further the effect of structural policy changes and the uprating of monetary parameters, which allows us to measure the extent of fiscal drag and benefit erosion in practice. The results show that despite different fiscal effects, policies overall mostly reduced poverty and inequality and both types of policy developments had sizeable effects on the income distribution. We also find that the uprating of monetary parameters not only had a positive effect on household incomes, meaning fiscal drag and benefit erosion were avoided, but generally also contributed more to poverty and inequality reduction than structural policy reforms.     

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.     

Fiscal Consolidations: A Theoretical Essay with a Heterogeneous-Agent Model

Since the emergence of the financial crisis, most of the EU countries have promoted impressive public interventions to support financial institutions, contributing to a significant rise in general government gross debt-to-GDP ratios. As such, the issue of how to best pursue a fiscal consolidation will become crucial regarding the fiscal policy stance. This paper aims at characterizing four different stylized debt consolidation strategies extensively identified in the literature (one pure revenue-based and three expenditure-based) in order to assess welfare affects and, in particular, the inequality effects involved. For this purpose, we built a general equilibrium heterogeneous-agent model capable of exploring the relationship between fiscal policy and the endogenous cross-section distribution of income and wealth. Moreover, we decompose the impacts on welfare criteria in order to distinguish pure efficiency effects from insurance and inequality effects. According to our simulations, the adjustment based on the reduction of unproductive expenditures came out to be the most welfare-enhancing compared to those based on tax increases or on social transfer reductions.     

Fiscal leadership and central bank design

Abstract.  This article investigates the impact, on economic performance, of the timing of moves in a policy game between the government and the central bank for a government that has both redistributional and stabilization objectives. It is shown that both inflation and income inequality are reduced without sacrificing output growth if the government assumes a leadership role compared with a regime in which monetary and fiscal policy are determined simultaneously. Further, it is shown that government leadership benefits both the fiscal and monetary authorities through the enhanced coordination that this arrangement implies.     

National numerical fiscal rules: Not complied with,but still effective?

This paper investigates the effects of (non-)compliance with national numerical fiscal rules on fiscal policy in 11 EU member states with 23 fiscal rules in place from 1994 to 2012. Introducing a new dataset of legal texts constituting the fiscal rules, allows a joint empirical analysis of different types and designs of numerical fiscal rules. In various empirical exercises the change in the difference between the exact variable constrained by the fiscal rule and its numerical limit is analysed. Statistics show that countries comply with their fiscal rules only in about 50% of the years. Nevertheless, various econometric exercises demonstrate that the introduction of fiscal rules does significantly change the behaviour of fiscal policy. If countries do not comply with their fiscal rule in the year or forecast before, there is a strong downward tendency of the constrained variable towards the numerical limit. The results show that fiscal rules act as kind of a benchmark for policy makers and the public, and even though they might be complied with only in half of the years, they still tilt fiscal policy towards the numerical limit in times of non-compliance.     

Income Taxation and the Diversity of Consumer Goods: A Political Economy Approach*

After‐tax income inequality has risen since the mid‐1990s, as increases in market income inequality have not been offset by greater fiscal redistribution. We argue that the substantial increase in the diversity of consumer goods has mitigated mounting political pressures for redistribution. Within a probabilistic voting framework, we demonstrate that if the share of diversified goods in the consumption bundle increases sufficiently with income, then an increase in goods diversity can reduce the political equilibrium tax rate. Focusing on OECD countries, we find empirical support for both the model's micro‐political foundations and the implied relation between goods diversity and fiscal policy outcomes.     

Growth and inequality in an endogenous fiscal policy model with taxes on labor and capital

I study an economy where individuals have different initial endowments and fiscal policy is decided by majority voting. Public investment is financed by two flat rate taxes, one on labor income and the other one on capital income. The model shows a positive (negative) correlation between growth and the tax rate on labor (capital) income and a negative (positive) correlation between the tax rate on labor (capital) income and inequality. The results reconcile the theory with empirical evidence.     

Fiscal Incidence in Ghana

We use methods developed by the Commitment to Equity Institute to assess the effects of government taxation, social spending and indirect subsidies on poverty and inequality in Ghana. We also simulate several policy reforms to assess their distributional consequences. Results show that, although the country has some very progressive taxes and well‐targeted expenditures, the extent of fiscal redistribution is small, but about what one would expect given Ghana's income level and relatively low initial inequality. Results for poverty reduction are less encouraging: were it not for the in‐kind benefits from health and education spending, the overall effect of government spending and taxation would actually increase poverty in Ghana. Eliminating energy subsidies and at the same time reallocating part of the savings to well‐targeted transfer programs could lower the fiscal deficit while reducing inequality and protecting the poor.     

The microfoundation of macroeconomic populism: The effects of economic inequality on public inflation aversion

Previous work on the politics of monetary policy has focused on the role of distributive motives stemming from individual characteristics such as income or factoral/sectoral interests in citizens' formation of monetary policy preferences. However, the existing literature has paid little attention to how a country's overall distributive context, namely, its level of economic inequality, affects citizens' preferences vis-à-vis price stability and employment. This article argues that as inequality pushes more citizens below a society's average income, there is more demand for redistribution through higher employment and increased fiscal spending, each of which can be better supported by expansionary monetary policy. This means that inequality makes citizens more tolerant of inflation. This study uses the International Social Survey Program, the Integrated Values Surveys, and the Comparative Study of Electoral Systems, which together include 293,100 respondents from 53 countries between the years 1976 and 2016 to demonstrate that overall, inequality significantly moderates citizens' inflation aversion.     

The Dutch experience: Assessing the welfare impacts of two consolidation strategies using a heterogeneous-agent framework

Between 1990 and 2010, the Dutch government pursued two successful fiscal adjustments: first, in 1995–2002, through a pure expenditure-based strategy and second, in 2004–2007, through a mixed strategy based on social transfer cuts and tax increases. In order to assess welfare and, in particular, inequality effects involved in each episode, we built a general equilibrium model with heterogeneous-agent capable of exploring the relationship between fiscal policy variables and the endogenous cross-section distribution of income, wealth and welfare.The results confirm that, for the Netherlands, a pure expenditure-based strategy is slightly superior relative a (partial) revenue-based one. In spite of positive welfare gains, the model predicts significant transition costs in both episodes due to depletion of insurance capacity, higher inequality and output losses. Moreover, as supported by the data, the model simulations show an improvement of the net foreign asset position in the sequence of the debt-consolidation processes. Finally, the two consolidation episodes, described throughout the paper strengthen the relevance of political institutions as important successful factors.     

Do dictatorships redistribute more?

This paper examines the effect of political institutions on fiscal redistribution for a country-level panel from 1960–2010. Using data on Gini coefficients before and after government intervention, we apply a measure of effective fiscal redistribution that reflects the effect of taxes and transfers on income inequality. Our findings clearly indicate that non-democratic regimes demonstrate significantly greater direct fiscal redistribution. Subsequently, we employ fiscal data in an attempt to enlighten this puzzling empirical finding. We find that dictatorial regimes rely more heavily on cash transfers that exhibit a direct impact on net inequality and consequently on the difference between market and net inequality (i.e., effective fiscal redistribution), whereas democratic regimes devote a larger amount of resources to public inputs (health and education) that may influence market inequality but not the difference between market and net inequality per se. We argue that the driving force behind the observed differences within the pattern on government spending and effective fiscal redistribution is that democratic institutions lead survival-oriented leaders to care more for the private market, and thus to follow policies that enhance the productivity of the whole economy.     

Monetary and fiscal policy interactions: Evidence from emerging European economies

This paper examines the interactions between fiscal and monetary policy for some former transition, emerging European economies over the 1995Q1–2010Q4 period by using a Markov regime-switching model. We consider the monetary policy rule proposed by Taylor (1993) and the fiscal policy rule suggested by Davig and Leeper (2007) in accounting for monetary and fiscal policy interactions. Empirical results suggest that monetary and fiscal policy rules exhibit switching properties between active and passive regimes and all countries followed both active and passive monetary policies. As for fiscal policy, the Czech Republic, Estonia, Hungary, and Slovenia seem to have alternated between active and passive fiscal regimes while fiscal policies of Poland and the Slovak Republic can be characterized by a single fiscal regime. Although the policy mix and the interactions between monetary and fiscal policy point a diverse picture in our sample countries, the monetary policy seems to be passive in all countries after 2000. This finding is consistent with the constraints imposed by European Union enlargement on monetary policy.     

Taking down the wall: Transition and inequality

In this article, we investigate the main determinants of income inequality in the transition countries of Central and Eastern Europe and the Commonwealth of Independent States during the period 1990–2018. To this end, we address a major methodological challenge that lies at the core of the cross‐country literature on income inequality: the potential endogeneity of income per capita, which is largely ignored by most empirical studies. We adopt a two‐pronged empirical strategy by (1) using trading partners’ weighted average real GDP as an instrumental variable and (2) estimating the model via the two‐stage least squares approach for static models and the generalized method of moments estimator for dynamic models. Our empirical findings are consistent with the Kuznets curve that illustrates a nonlinear relationship between income inequality and the level of economic development. We also find that the redistributive impact of fiscal policy is statistically insignificant and taxation and government spending appear to have the opposing effects on income inequality in transition economies over the sample period.     

Finance commission of India’s assessments: a political economy contention between expectations and outcomes

We explore the normative fiscal assessments of the Finance Commission (FC) of India, and realisation of fiscal policy with regard to Central Finances over the period 1990–2012. We employ the Theil’s inequality coefficient to investigate the magnitude of assessment errors and its partitioning in to bias, slope and random components. Furthermore, this article also evaluates the efficiency, biasedness and persistence of forecast errors. The robustness of the efficiency results are confirmed with the application of maximum entropy bootstrap. The objective of this study is to examine the structural basis on which FCs make their awards rather than examining the predictability of the forecasts. The story of FC’s assessments reflects an interesting political economy theatre of contention between aspirations and outcomes. Our key findings are as follows: First, source of errors for assessments of tax revenue, nontax revenue, interest payments, defence revenue expenditure, plan revenue expenditure and fiscal deficit is principally due to random component. However, the errors in the remaining economic parameters originate due to systematic components i.e. mean and slope errors. Second, the expenditure side predictability is lower than the revenue side predictability.     

Effectiveness of Fiscal Policy in a Model of Imperfect Competition With Transactions Money

This paper examines the effectiveness of fiscal policy in a general equilibrium macromodel with transactions money and an oligopolistic product market. The results suggest that although money may be neutral and play no direct role as a policy instrument, its indirect impact on the effectiveness of fiscal policy can be quite substantial. In particular, when money balances feature as a choice variable in the households' objective function, (i) fiscal policy becomes ineffective as the weight attached to money is reduced; (ii) the fiscal multiplier becomes negative when the elasticity of substitution between money and leisure exceeds unity; and (iii) it is possible that policy effects are in fact enhanced as the product market becomes more competitive.
