Political economy of income distribution dynamics

Income distribution varies considerably across countries; it tends to become more equal with development in some countries, but just the opposite occurs in other countries. This paper provides a theoretical investigation of the persistent differences in income distribution across countries over time. Motivated by the relationship between income distribution and public spending at different school levels for a broad range of countries over the past 30 years, the analysis centers on the role of public education where specific investments interact with political involvement by different socio-economic groups. Socio-economic groups may form lobbies to influence education policy making. The formation of lobbies is endogenous. Persistent inequality is caused by persistent lobbying efforts of the wealthy that lead to an allocation of public education spending more biased toward them.     

A quantitative analysis of Turkish Private Education Reform

A recent education policy Turkish government is wishing to undertake is to shut down all private supplementary education centers (SECs) unless SECs manage to convert into a private school. With this policy, the government is willing to increase equality of opportunity among students. We show quantitatively that the policy, in fact, leads to a decrease in equality of opportunity since SECs are given the option to convert into private schools. We use a political economy model of education at which households, heterogeneous with respect to exogenously set income, choose among a continuum of private schools differentiated by tuition and a public school. Households choosing the public school can privately supplement their child's education spending in any amount. Public school is free of charge, and its spending is financed by income tax revenue collected from all households. Income tax rate is determined by majority voting. Achievement of a child depends only on educational spending. We calibrate the model's parameters by matching certain targets from 2013 Turkish data. We then exogenously restrict the supplemental education spending to zero in a counterfactual experiment. We find that variance of achievement (or inequality of opportunity) increases by 23.51% and mean achievement decreases by 1.74%.     

Who benefits from big government? A life satisfaction approach

Which impact does government size have on life satisfaction, and how do effects of bigger government differ between income groups in society? Previous studies typically employed country averages and thus neglected possibly heterogeneous happiness effects between income groups. This paper addresses empirically the effects of government spending on subjective well-being of individuals belonging to different income groups. Our analysis is based on individual data from 25 European countries participating in the European Social Survey. In contrast to most previous studies we take account of the endogeneity between relative income position and reported life satisfaction by an instrumental variable approach. Our results suggest, first, that most government spending categories, including social protection, are on average negatively related to individual well-being. Secondly, estimated marginal effects of health, education and social protection spending at different income levels show that spending increases always have a stronger negative effect on high income groups’ well-being than on low income groups’ life satisfaction. For all government spending categories, marginal happiness effects of higher public spending are clearly negative for income groups at the top.

The political economy of public education

I study the relationship between income inequality and public spending in education in a voting model. Voters collectively choose the uniform quality level of public education, the amount of a public good, and the tax rate on labor income. Parents can decide to opt-out of the public education system by purchasing private education at the desired quality level, and children’s expected income is assumed to be increasing in the quality of education. I show that higher income inequality is associated with higher governmental spending in education if and only if the expected marginal returns to education are larger for the children of relatively low income parents. In turn, better public education tends to reduce future inequality. These results are consistent with most findings in the empirical literature about public investment in education. Lastly, I show that for other kind of publicly provided goods, such as health care, the relationship with income inequality exhibits an ambiguous or opposite sign.     

Individual preferences for public education spending: Does personal income matter?

Standard redistributive arguments suggest that the impact of household income on preferences for public education spending should be negative, because wealthier families are likely to oppose the redistributive effect of public funding. However, the empirical evidence does not confirm this prediction. This paper addresses this ‘puzzle’ by focusing on the role of the inclusiveness of the education system and the allocation of public spending between tiers of education in shaping the impact of income on preferences. By using data from the International Social Survey Programme (2006), we show that, when access to higher levels of education is restricted (low inclusiveness) and when the share of public spending on tertiary education is high, the poor are less likely to support public education spending. This result suggests that reforming the education system towards greater inclusiveness might contribute to increase political backing for public investment in education from the relatively poor majority of the population.     

企业行为约束下技术创新所得税激励政策效应研究

技术创新所得税激励政策效应的发挥不但取决于政策本身的制度设计,还取决于企业投资行为对税收政策的敏感性。技术创新所得税激励政策作为制度驱动,既受到企业自身行为的约束,又与企业内部研发驱动机制相互作用。在企业行为理论框架下,运用随机效应模型,以2009—2013年中国Ａ股上市公司数据为样本,对企业行为约束下中国技术创新所得税激励政策效应进行了理论分析和实证检验。结果发现,税收优惠政策形成的税收补贴通过转化为企业内部资源、降低研发投资风险,使得企业内部驱动机制对研发支出的积极作用增强;所得税激励政策本身并未对企业技术创新活动产生显著的激励作用。     

RE-EXAMINING THE EFFECTIVENESS OF STABILISATION POLICY

This paper develops an alternative international macroeconomic model for evaluating the effectiveness of fiscal and monetary policy in stabilising national income under fixed and floating exchange rates. It encompasses national output and income, saving, investment, money and capital flows and linkages between the exchange rate, price levels and real interest rates consistent with international parity conditions. It demonstrates that the nature of government spending is pivotal to the effectiveness of fiscal policy, revealing that, ceteris paribus , higher public consumption expenditure contracts national income and depreciates the exchange rate, whereas higher productive public investment spending has opposite effects. The framework also shows that the effectiveness of fiscal and monetary policy as macroeconomic policy instruments is not ultimately dependent on the exchange rate regime.     

Functional components of public expenditure,fiscal consolidations,and economic activity

This paper analyses how the functional components of public expenditure and spending‐driven consolidations affect the economic growth, unemployment, and income inequality. A dynamic panel data least squares dummy variable estimator estimator is employed over a sample of 15 European Union countries during the period 1990–2012. The empirical results show that real GDP growth decreases when fiscal austerity measures are implemented, especially if they are spending‐driven. Cuts in public expenditure undermine economic growth, namely if they slash spending on public order, recreation, and education. Spending cuts on education, in particular, affect the investment in human capital, harming not only growth but also economic, social, and human development. The unemployment rate also proved to be significantly boosted when austerity measures restrict spending on education, whereas income inequality rises when social protection expenditures are cut.     

Optimal time-consistent fiscal policy under endogenous growth with elastic labor supply

We explore the implications of incorporating an elastic labor supply in an endogenous growth economy when characterizing the time-consistent Markov policy. We consider two policy instruments: an income tax rate and the split of government spending between consumption and production services. The Markov-perfect policy implies a higher income tax rate and a larger proportion of government spending allocated to consumption than those chosen under a commitment constraint on the part of the government. As a consequence, economic growth is slightly lower under the Markov-perfect policy than under the Ramsey policy. Under the Markov and Ramsey optimal policies, a higher weight of leisure in households' preferences leads to a lower optimal income tax rate and a lower proportion of public resources devoted to consumption. We also show that the policy bias that would arise when imposing a Markov policy designed ignoring the presence of leisure in the utility function would lead to a significant welfare loss.     

The dual nature of public goods and congestion: the role of fiscal policy revisited

Abstract The role of fiscal policy is examined when public goods provide both productive and utility services. In the presence of congestion, the consumption tax is shown to be distortionary. Optimal fiscal policy involves using consumption‐based instruments in conjunction with the income tax. An income tax‐financed increase in government spending dominates both lump‐sum and consumption tax‐financing. Replacing the lump‐sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax. These results contrast sharply with the literature, where the consumption tax is generally viewed as the least distortionary source of public finance.     

The role of Provincial Government Spending Composition in growth and convergence in China

China’s development policy since 1978 has differed across regions. With rapid aggregate growth has come widening regional inequality. The fiscal decentralisation reforms in 1994 shifted political pressure onto provincial officials to boost local growth through local public investments. These investments affect regional convergence by counteracting regulatory frictions in factor accumulation, and can also determine steady-state growth. However, the effect of public spending allocations across physical and human capital on growth and convergence processes is empirically unexplored for Chinese provinces. We take provincial time-series data on public spending by category, finding local public spending and its components augment convergence rates differently across regions. Spending on education and health contributes significantly more to growth and convergence than capital spending, confirming that the public capital-spending bias is not a local growth-optimising strategy. We suggest a policy of aligning local government promotion incentives to human capital targets to correct local resource misallocation.     

Is the median voter decisive? Evidence from referenda voting patterns

This paper examines whether the voter with the median income is decisive in local spending decisions. Previous tests have relied on cross-sectional data while we make use of a pair of California referenda to estimate a first difference specification. The referenda proposed to lower the required vote share for passing local educational bonding initiatives from 67 to 50% and 67 to 55%, respectively. We find that voters rationally consider future public service decisions when deciding how to vote on voting rules. However, the empirical evidence strongly suggests that an income percentile below the median is decisive for majority voting rules, especially in communities that have a large share of high-income voters with attributes that suggest low demand for public services. Based on a model that explicitly recognizes that each community contains voters with both high and low demand for public school spending, we also find that an increase in the share of low demand voters is associated with a lower decisive voter income percentile for the high demand group. This two type model implies that our low demand types (individuals over age 45 with no children) have demands that are 45% lower than other voters. Collectively, these findings are consistent with high-income voters with weak preferences for public educational services voting with the poor against increases in public spending on education.     

Macroeconomic impacts of fiscal policy shocks in the UK: A DSGE analysis

This paper develops and estimates a new-Keynesian dynamic stochastic general equilibrium (DSGE) model for the analysis of fiscal policy in the UK. We find that government consumption and investment yield the highest GDP multipliers in the short-run, whereas capital income tax and public investment have dominating effect on GDP in the long-run. When nominal interest rate is at the zero lower bound, consumption taxes and public consumption and investment are found to be the most effective fiscal instruments throughout the analysed horizon, and capital and labour income taxes are established to be the least effective. The paper also shows that the effectiveness of fiscal policy decreases in a small open-economy scenario and that nominal rigidities improve effectiveness of public spending and consumption taxes, whereas decrease that of income taxes.     

EXPANSIONARY VERSUS CONTRACTIONARY GOVERNMENT SPENDING

This article theoretically examines the impact of different forms of government spending on national income in a financially open economy with a significant net international investment position the central bank of which sets domestic interest rates to target inflation. It shows that whether government spending is expansionary or contractionary ultimately depends on the productivity of that expenditure, a result that has major implications for the efficacy of fiscal policy deployed for either stimulus or austerity reasons. The key prediction of the model is that public consumption and unproductive public investment are procyclical, whereas only productive public investment is countercyclical. (JEL F41)     

Human Capital Theory and Education Policy in Australia

The human capital model is the basis of neo-classical analysis of labour markets, education and economic growth. However, education policy in Australia has been influenced by models based on screening theory and public choice theory which yield the policy implication that reductions in education spending are generally desirable. In this paper, the competing models, and the evidence supporting them, are surveyed. It is concluded that the human capital model is strongly supported by the available evidence. The predictions of screening models are generally not supported by empirical tests, except where they coincide with those of the human capital model. The main evidence supporting the public choice model, derived from the literature on educational production functions, is shown to be deficient. The principal policy conclusion of the paper is that the negative effects of recent cuts in education spending will outweigh any benefits achieved through reductions in public debt.     

A Synthesis of Contour and Flexible Wage Hypotheses

Economic instability has risen in emerging economies after capital account liberalization. A more progressive income tax policy could offer a stabilizing alternative. It could result in more revenue, more countercyclical policy, and more income equality and thus more stable demand growth. We test the effects of progressive taxes on stability using univariate and multivariate analyses based on panel data for emerging economies from 1982 to 2002 and compare those to the effects of a value added tax (VAT). We also consider possible constraints on tax policy design, such as government spending, international tax competition, and openness. Progressive taxes are associated with greater income equality and a higher likelihood of countercyclical fiscal policies. The potential benefits from progressive income taxation, though, are lower with VAT. Tax policy is also constrained by government expenditures and openness, but not by lower corporate taxes, suggesting that all income tax rates are constrained by openness.     

The Efficiency of State Taxes on Mobile Labour Income

We model a federation where States levy a tax on the wage income of mobile citizens who shop between States for their preferred tax and public policy package. It is shown that competition between States results in efficient State spending but that the taxes on wage income are inefficient in the sense that mobile taxpayers are allocated inefficiently across States. The implication is that if States tax the wage income of mobile workers, there may be benefits from policy competition (a more competitive federal system) but also costs associated with the inefficiency. The central government can correct for the inefficiency, but this requires a complex system of inter-State transfers that are difficult to implement in practice.     

Keynes,Employment Policy and the Question of Public Debt

This article provides a simple formalization of income–expenditure equilibrium in accordance with the Principle of Effective Demand, but augmented to explicitly incorporate public debt. This is utilized to explore the conditions required for simultaneous achievement of full-employment growth and a sustainable public debt trajectory—the latter understood as stabilization of the ratio of public debt to aggregate income, at some desired level. In the spirit of Keynes's economics, demand-led, full-employment growth, driven by government spending, is reconciled with public debt sustainability so understood. The policy implications, illustrative of Keynes's policy views, are then drawn out.     

Public Investment and Economic Growth in Latin America: an Empirical Test

The paper analyzes the impact on economic growth of public investment spending and other relevant variables (such as human capital) for nine major Latin American nations over the 1983–93 period. The results suggest that both public and private investment spending contribute to economic growth. Overall central government consumption expenditures, on the other hand, are found to have a negative effect on private investment and growth. Finally, public expenditures on education and healthcare are found to have a positive and statistically significant effect on private capital formation and long–term economic growth. From a policy standpoint, the results suggest that indiscriminate cuts in public and private investment spending are likely to be counterproductive in the long run, and more importantly, scarce public expenditures should be channeled to the promotion of new human capital (via primary and secondary education) and the maintenance of existing human capital (through healthcare expenditures).
