公共支出结构对收入不均等影响研究——基于公共服务均等化视角分析

收入不均等影响到社会公平与经济发展,而收入公平分配是政府的主要责任,也是政府公共支出的依据之一.影响收入分配不均等的因素有很多,其中由于政府相应责任缺位,公共支出结构偏向,使得公共支出中基本公共服务支出不足是其主要原因.本文实证分析得出公共支出总量与结构严重影响基本公共服务供给,进而影响着收入不均等的水平,成为社会公平和稳定的重要因素.政府应从制度上进行公共支出改革,规范督促地方政府优化公共支出结构,不断提高对民生支出的主动性,逐步缩小基本公共服务的差距,缩小收入不均等的水平.     

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.     

Fiscal financing and the efficacy of fiscal policy in Korea: An empirical assessment with comparison to the U.S. evidence

This paper aims to assess the empirical implications of fiscal financing in Korea and study how they differ from those of the U.S. We estimate two versions of the dynamic stochastic general equilibrium (DSGE) model—a small open economy (SOE) model for Korea and its closed economy counterpart for the U.S.—in which the former nests the latter as a special case. The fiscal policy specification posits that government spending, lump-sum transfers, and distortionary taxation on labor income, capital income and consumption expenditures respond to the level of government debt and the state of economic activity. Analysis of the data from 2000 to 2015 shows that distortionary capital taxes play a critical role in stabilizing government debt in the U.S., whereas non-distorting fiscal instruments are the primary means of fiscal adjustment in Korea. Regarding the magnitude of debt-financed fiscal stimuli, the substantial trade openness of Korea is significant in that it produces relatively smaller government spending and transfer multipliers compared to the U.S.     

The impact of oil prices on income and energy

The major determinant of real income growth in Korea is real oil prices, followed by money supply, exchange rates, energy consumption, and government spending. Over the longer horizon, the effects of exchange rates, oil prices, government spending, and money supply become more pronounced. For energy consumption, the most important factor is oil prices, followed by exchange rates, government spending, money supply, and income. For the association between energy consumption and real income, energy consumption influences real income growth only through energy consumption, while real income affects energy consumption only through the error correction term. The findings of the study thus suggest that the level of economic activity and energy consumption mutually influence each other.     

Useful Government Spending and Macroeconomic (In)stability under Balanced-Budget Rules

It has been shown that an otherwise standard one‐sector real business cycle model may exhibit indeterminacy and sunspots under a balanced‐budget rule that consists of fixed and “wasteful” government spending and proportional income taxation. However, the economy always displays saddle‐path stability and equilibrium uniqueness if the government finances endogenous public expenditures with a constant income tax rate. In this paper, we allow for productive or utility‐generating government purchases in either of these specifications. It turns out that the previous indeterminacy results remain unchanged by the inclusion of useful government spending. By contrast, the earlier determinacy results are overturned when public expenditures generate sufficiently strong production or consumption externalities. Our analysis thus illustrates that a balanced‐budget policy recommendation which limits the government's ability to change tax rates does not necessarily stabilize the economy against belief‐driven business cycle fluctuations.     

Public debt in a basic endogenous growth model

We work out the mechanism that makes public debt affect the allocation of resources in the long-run. To do so we analyze an AK growth model with elastic labor supply and a government sector. The government levies a distortionary income tax and issues bonds to finance lump-sum transfers and non-distortionary public spending. We show that the long-run growth rate is the smaller the higher the debt ratio if the government adjusts public spending to fulfill its inter-temporal budget constraint. If the government adjusts lump-sum transfers the public debt ratio does not affect the balanced growth rate.     

MULTIPLIER EFFECTS OF PUBLIC SERVICES IN A TWO‐SECTOR MODEL OF MONOPOLISTIC COMPETITION

In a two‐sector model of monopolistic competition, this paper explores what impacts an expansion of government spending on public services has on national income. In the short run where entry and exit of firms are restricted, a rise in government spending on services like health care (which has only a role of substituting for market services) increases national income, but that on services like elderly care (which has not only this role but also another role of contributing to home production of services) decreases it. These results are reversed in the long run. Welfare effects of public services are also examined.     

Can productive government spending be a source of equilibrium indeterminacy?

This paper presents an examination of the interaction between indeterminacy and productive government spending financed by taxes in a one-sector growth model. In the paper, we show that the possibility of indeterminacy is positively affected by dependence on income tax financing and is negatively affected by consumption tax financing. Under balanced budget rules, a key determinant for indeterminacy is a revenue source for providing public services (i.e. income tax financing) rather than the presence of productive government spending.     

Diaspora and government welfare spending: Do migrant remittances increase public social protection?

This paper contributes to the debate on the impact of migrant remittances on welfare spending. It empirically examines the influence that remittances have on public social protection (SP) expenditures using macrolevel panel data on a sample of 38 high‐ and middle‐income countries over the period 2005–2014. The paper finds that remittances have a negative influence on public SP expenditures, suggesting that they serve as a private substitute to public SP. The results highlight the importance of remittances to government welfare spending and sustainable development.     

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.     

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)     

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.     

Reconsidering Wagner’s law: evidence from the functions of the government

We revisit Wagner’s law by function of government expenditure. Using data of 14 European countries between 1996 and 2013, we apply panel data and SUR methods to assess public expenditure–income elasticities. We find that some functions of government spending for a few countries (e.g. Austria, France, the Netherlands and Portugal) validate Wagner’s law. For the Netherlands, expenditures with environment protection increase more than proportionately to economic growth, and for France that is the case of spending in housing and community amenities. In addition, Greece is the only country where two public spending items react more than one to one to growth.     

财政政策、货币政策与国外经济援助

本文通过把国外经济援助分成直接对私人的经济援助和直接对政府的经济援助来讨论这两类经济援助对政府财政政策和货币政策的影响。我们发现对私人的经济援助的增加可以使得私人消费水平和政府公共消费水平增加 ,但是它也导致政府收入税税率和通货膨胀率的提高 ;另一方面 ,对政府的经济援助增加可以使得均衡时的私人资本存量、私人消费水平和政府公共消费水平增加 ,同时可以使得均衡时的收入税税率和通货膨胀率下降。     

Social security, public education and the growth-inequality relationship

We study how the relationship between economic growth and inequality depends upon the levels of funding of two of the largest government programs, public education and social security. We do this in the context of an overlapping generations economy with heterogeneous agents where the government collects a tax on labor income to finance these programs. We show that in our model an increase in government spending on social security reduces income inequality and can have a non-monotonic effect on growth. When the initial level of social security funding is low, as is the case in most poor economies, then its increase will enhance growth. When its funding level is high as is typical for developed countries, we show that its further increase can slow down growth while reducing income inequality. These results obtain regardless of whether the increase in social security funding is financed by a tax increase or by cutting the public education budget. We also find that the effects of increasing the level of public education expenditures or the overall size of the government budget (holding the budget composition fixed) are characterized by similar non-monotonic growth-inequality relationships.     

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.     

Efficient government size: France in the 20th century

The benefits and costs of government suggest an efficient government size. We investigate efficient government size by analyzing the relation between public spending and real GDP for France in the period 1896–2008. The results show a co-integration nonlinear relationship. Our time-series data on France represents one of the longest periods studied in literature. Our empirical findings suggest that efficient government size measured by public spending was reached when public spending was around 30% of GDP. Conclusions point to particularities of countries that suggest efficient government size is specific to different countries.     

Preferences and demand for local public spending

In this paper we present logit estimation results for individual demand equations for local public spending. Our data are derived from a large-scale survey, organized by a Belgian municipality. Respondents were informed that the results of the survey would influence actual decisions and the questions covered very specific projects and their immediate tax consequences. Sociological variables are dominant in the explanation of the willingness-to-pay for specific projects, while the explanatory value of income is limited. We also analyse the global choice between public and private spending: here income and education are the most important variables, and both have a positive effect on the demand for public spending. Fiscal ignorance is widespread but does not lead to a higher demand for public spending.     

Intergenerational Allocation of Government Expenditures: Externalities and Optimal Taxation

This paper studies optimal capital and labor income taxes when the benefits of public goods are age‐dependent. Provided the government can impose a consumption tax, it can attain the first‐best resource allocation. This involves the uniform taxation of the cohorts' labor income and a zero capital income tax. With no consumption tax and optimally chosen government spending, labor income should be taxed nonuniformly across cohorts and the capital income tax should be nonzero. Deviations of the public goods from their respective optima create distortions. These affect the labor supply decisions of both cohorts and capital accumulation, providing a further reason to tax (or subsidize) capital income.     

Balanced-budget rules and macroeconomic (in)stability

It has been shown that under perfect competition and constant returns-to-scale, a one-sector real business cycle model may exhibit indeterminacy and sunspots when income tax rates are determined by a balanced-budget rule with a pre-set level of government expenditures. This paper shows that indeterminacy disappears if the government finances endogenous public spending and transfers with fixed income tax rates. Under this type of balanced-budget formulation, the economy exhibits saddle-path stability and equilibrium uniqueness, regardless of the source of government revenue and/or the existence of lump-sum transfers.
