Production subsidies and redistribution

Who gains from stimulating output? We explore a dynamic model with production subsidies where the population is heterogeneous in one dimension: wealth. There are two channels through which production subsidies redistribute resources across the population. First, poorer agents gain from a rise in wages, since—to the extent there is an operative wealth effect in labor supply—they work harder. Second, because a current output boost will raise consumption today relative to the future, thus lowering real interest rates, poor agents gain in relative terms since their income is based less on interest income. We examine optimal redistribution from the perspective of an arbitrary consumer in the population. We show that, if this consumer has commitment at time zero to set all present and future subsidy rates, and for a class of preferences that admits aggregation in wealth, then output stimulation, and hence redistribution, will only occur at time zero; after that, subsidies are zero. A byproduct of our analysis of this environment is a median-voter theorem: with direct voting over subsidy sequences at time zero, the sequence preferred by the median-wealth consumer is the unique outcome. We also study lack of commitment, since interest-rate manipulation is associated with time inconsistency. We analyze this case formally by looking at the Markov-perfect (time-consistent) equilibrium in a game between successive identical decision makers (e.g., the median agent). Here, subsidies persist—they are constant over time—and are more distortionary than under commitment. Moreover, whereas under commitment asset inequality changes initially—in favor of the consumer who decides on policy—it does not under lack of commitment.     

Optimal renewable-energy promotion: Capacity subsidies vs. generation subsidies

We derive optimal subsidization of renewable energies in electricity markets. The analysis takes into account that capacity investment must be chosen under uncertainty about demand conditions and capacity availability, and that capacity as well as electricity generation may be sources of externalities. The main result is that generation subsidies should correspond to externalities of electricity generation (e.g., greenhouse gas reductions), and investment subsidies should correspond to externalities of capacity (e.g., learning spillovers). If only capacity externalities exist, then electricity generation should not be subsidized at all. Our results suggest that some of the most popular promotion instruments cause welfare losses. We demonstrate such welfare losses with data from the German electricity market.     

Global capital markets,direct taxation and the redistribution of income

Standard fiscal theory suggests that taxation should be heaviest on the least mobile factors of production – for both efficiency and revenue reasons. A shift in tax burdens from capital to labour as economies become globally integrated is thus justified. This theoretical tradition (founded by Ramsay and continued by Mirrlees and Lucas) assumes by construction that profit taxes reduce investment and growth; and while sensitive to inter-generational equity, sidesteps the issue of income distribution within generations. In contrast, starting from Keynes’ critique of these assumptions and building on modern endogenous growth models, it can be shown that profit taxation is not necessarily injurious to productive investment. In practice, moreover, the effect of globalisation has not been to reduce tax rates on capital, but rather to erode the tax base itself (i.e. ‘tax evasion’). Improved information exchange between tax authorities, which is now being driven by fiscal insolvency in developed countries, would allow tax incidence to be shifted so as to improve income distribution within OECD countries. Such cooperation could also permit the replacement of the current discretionary system of fiscal transfers from rich to poor countries (‘development aid’) by equitable sharing of global capital tax revenue.     

Finance,income inequality and income redistribution

Using a panel fixed effects model for a large sample of countries covering 1975–2005, we test the hypothesis that income inequality caused by finance (financial development, financial liberalization and banking crises) is related to more income redistribution than inequality caused by other factors. Our results provide evidence in support of this hypothesis. We also find that the impact of inequality on redistribution is conditioned by ethno-linguistic fractionalization. Our findings are robust to the inclusion of several control variables suggested by previous studies.     

Consumption smoothing and income redistribution

We show theoretically that income redistribution benefits borrowing-constrained individuals more than is implied by standard relative-income and uninsurable-risk considerations. Empirically, we find in international opinion-survey data that younger and lower-income individuals express stronger support for government redistribution in countries where consumer credit is less easily available. This evidence supports our theoretical perspective if such individuals are more strongly affected by tighter credit supply, in that expectations of higher incomes in the future increase their propensity to borrow.     

Dealing with monopsony power: Employment subsidies vs. minimum wages

We show in a monopsony model that accounting for changes in hours a minimum wage has ambiguous effects on employment and welfare. When all workers have the same preference ordering over leisure and consumption employment subsidies unambiguously improve welfare. Many countries have minimum wages and also tax minimum wage workers.     

Emission taxes vs. financial subsidies in pollution control

The polluting firm is modelled as a multi-product firm where one process produces the product and the residual as a by-product. A second process neutralizes a part of the residual harmless to the environment. We show that the subsidies to a residual abating input do not necessarily lead to a reduction in the emission into the environment, whereas the emission taxes do.     

Immigration and income redistribution in welfare states

This paper sets out a political economy model where median voters who benefit from local income redistribution are affected by the fiscal burden of welfare payments to immigrants. The median voters also have cultural preferences. Immigrants are influenced in their relocation decision by welfare benefits in host countries. Uncoordinated, coordinated and leader–follower domestic welfare policies are compared. In the last case, the median voter in the follower country is better off than the median voter in the leader country because of a less generous welfare system and hence fewer immigrants.     

Risky business: Institutions vs. social networks in FDI

Political economy scholarship on foreign direct investment (FDI) emphasizes variation in host country political risk but overlooks variation in investors' sensitivity to political risk. We show that relational contracting, relationship‐based contract enforcement, is more efficient for high‐risk, human capital‐intensive activities for which the costs of writing legally enforceable contracts are prohibitive. We disaggregate FDI into two distinct varieties: mergers and acquisitions (M&A) and venture capital (VC). We propose that VC flows are less sensitive to host institutions but correlate strongly with skilled migrant networks that monitor compliance and impose reputational costs. Our empirical analysis of dyadic VC and M&A flows covers over 100 countries during 1980–2009. We address other mechanisms through which migrant networks facilitate FDI and verify our results hold at the country‐industry level. These findings suggest that relational contracting facilitates global integration of dynamic, knowledge‐intensive industries even when formal institutions are weak.     

Special interest politics: Contribution schedules vs. Nash bargaining

The article compares two models of lobby influence on policy choice: The Grossman and Helpman (1994) contribution‐schedules model and a negotiation between the lobbies and the government summarized by a Nash‐bargaining function. The literature uses the models interchangeably because they imply the same equilibrium policy. We show that particular assumptions about bargaining power and disagreement utility in the Nash‐bargaining solution are required for the models to lead to the same equilibrium payments and utilities. This implies that the models usually imply different sets of lobbies if lobby formation is an endogenous decision, such that the equilibrium policies also differ.     

Consumer's surplus and income redistribution

In reformulating consumer's surplus analysis, Hicks focused on a single household. The present essay extends the analysis to many households in a manner that seems not yet to have been explored systematically: by integrating consumer's surplus with the social welfare function. This is done in a general, as distinct from the usual partial, equilibrium context. A resulting formula, relating the community's gain from a resource reallocation in a novel way to the associated changes in volume and distribution of income, inclusive of surpluses, may facilitate applications. The analysis may also clarify some recurring issues regarding consumer's surplus.     

Flat income taxation,redistribution and labour market performance

A flat tax rate on labour income has gained popularity in European countries. This article assesses the attractiveness of such a flat tax in achieving redistributive objectives with the smallest distortions to employment. We do so by using a detailed applied general equilibrium model for the Netherlands. The model is empirically grounded in the data and encompasses decisions on hours worked, labour force participation, skill formation, wage bargaining between unions and firms and a wide variety of institutional details. The simulations suggest that the replacement of the current tax system in the Netherlands by a flat rate will harm labour market performance if aggregate income inequality is contained. Only flat tax reforms that reduce redistribution will raise employment. This finding bolsters the notions from optimal tax literature regarding the equity-efficiency trade off and the superiority of nonlinear taxes to obtain redistributive goals in an efficient way.     

Trade,growth and income redistribution: A case study of India

The concern of this exercise is with the effectiveness of trade policies and their assessment in achieving economic growth and income equality. A link between growth and equality is provided through employment. If there is substantial increase in employment, the inequality of income distribution is likely to be reduced. Thus, trade by bringing about higher levels of production and employment may reduce income inequality. We have applied a closed input-output model to the Indian data to estimate the interrelationships between trade, growth and income redistribution. It has been found that employment opportunities could be raised substantially through redistribution as well as through export promotion in developing countries such as India, if capital and foreign exchange constraints are not binding. Import substitution, however, does not turn out to be as effective a strategy to achieve these goals.     

Two polar cases of dynamic stability: voluntary exchange and income redistribution

Summary. It is known that when voluntary exchange is permitted at disequilibrium, dynamic stability may fail because of lack of liquidity. In this paper it is shown that when the economy runs out of liquidity dynamic stability can still be restored by means of a planning procedure of redistributing personal incomes.Received: 30 May 2003, Revised: 20 January 2005, JEL Classification Numbers: D01, D50.I wish to thank a referee for helpful comments.     

Investment subsidies and redistributive capital income taxation in a neoclassical growth model

How do investment subsidies bear on pure redistribution when coupled with capital income taxes? In a heterogeneous agent, neoclassical growth framework it is found that on impact, with no optimizing behavior, investment subsidies are good for growth but bad for redistribution. The opposite holds for capital income taxes. But when the government acts as a Stackelberg leader vis-à-vis the private sector (the follower), the optimal feedback policy is by construction time-consistent and implies that in a long-run optimum the tax scheme does not distort accumulation. This holds regardless of social preferences. For the feedback Stackelberg equilibrium I find that (pure) redistribution can go either way and capital income taxes are nonzero in the long-run, time-consistent optimum, depending on the social weight of those who receive redistributive transfers, the distribution of pretax factor incomes, and the intertemporal elasticity of substitution. It is argued that investment subsidies may be an important indirect tool for redistribution, and may allow for the separation of “efficiency” and “equity” concerns.     

International tax arbitrage and residence vs. source-based capital income taxation

Using a two-country general equilibrium framework with heterogeneous agents and uncertainty, we examine how countries' adoption of different fundamental approaches to taxing international capital income will affect portfolio choices and pricing relationships in international bond and foreign exchange markets. We characterize an equilibrium where (tax-)arbitrageurs in the country applying the source principle may exploit the resulting tax arbitrage opportunities up to some individual bound, normal investors in either country refrain, or are restrained, from constructing such (tax-)arbitrage portfolios, while arbitrageurs in the country using the residence principle do not share in any tax arbitrage profits.     

Technology diffusion and global welfare effects: Imitative R&D vs. South-bound FDI

A country in question is positioned in the middle of a global technology race. To shorten its technology gap with the forerunner (North), this middle country must invest in imitative R&D. To exploit cheap labor in the technological laggard (South), it also must invest in South-bound FDI. A dynamic general-equilibrium model of three countries (North, Middle, South) is set up to numerically analyze how the Middle’s refraining South-bound FDI affects international technology diffusion, international wage gaps, and international welfare. The Middle always finds a need to socially optimize investing balance between imitative R&D and South-bound FDI, while the South is instead in favor of as much South-bound FDI as possible. Interestingly, the North may, or may not, align with the Middle’s tightening South-bound FDI, depending on how fast the Northern product innovation can proceed over time. Both transitional dynamics and the steady-state equilibrium are computed.     

Endogenous human capital accumulation, comparative advantage and direct vs. indirect redistribution

Recently, several papers have reexamined the so-called production efficiency theorem and the Atkinson and Stiglitz theorem on commodity taxes in the optimal taxation literature. Naito [J. Public Econ. 71 (1999) 65] showed that indirect redistribution through production distortion or consumption distortion can Pareto-improve welfare and that the two theorems do not necessarily hold when different factors are imperfect substitutes and factor prices are endogenous. On the other hand, Saez J. Public Econ. (2002) forthcoming argued that in the long run, where human capital accumulation is endogenous, the two theorems are still valid. This paper develops reasonable alternative models where individuals accumulate human capital based on their comparative advantage. The present paper shows that the production efficiency theorem is not necessarily valid and that indirect redistribution from the able to the less able such as tariffs and production subsidies can increase efficiency even when skill accumulation is endogenous.
