Wealth inequality and collective action

We study the effect of inequality in the distribution of endowments of private inputs (e.g., land, wealth) that are complementary in production with collective inputs (e.g., contribution to public goods such as irrigation and extraction from common-property resources) on efficiency in a class of collective action problems. We focus on characterizing the joint surplus maximizing level of inequality, making due distinction between contributors and non-contributors, in a framework that allows us to consider a wide variety of collective action problems ranging from pure public goods to impure public goods to commons. We show that while efficiency increases with greater equality within the groups of contributors and non-contributors, so long the externalities (positive or negative) are significant, there is an optimal degree of inequality between these groups.     

Public Good Mix in a Federation with Incomplete Information

We analyze a model of resource allocation in a federal system in which the center transfers real resources between member states. The center is assumed to be unable to observe the precise value of the cost differences across jurisdictions that motivate the transfers. Moreover, the center cannot observe the output levels of the individual local public goods provided by the jurisdictions, but must condition its transfers on a coarse aggregate of expenditures on public goods. We find that when the jurisdiction with private information realizes a high unit cost, it is generally worthwhile for the center to allow it a level of expenditure on public goods that differs from the "first best" level. However, whether that level is higher or lower than its first best level depends on the magnitudes of demand parameters for the local public good.     

Strategy-proof allocation mechanisms for economies with public goods

We show that strategy-proof allocation mechanisms for economies with public goods are dictatorial—i.e., they always select an allocation in their range that maximizes the welfare of the same single individual (the dictator). Further, strategy-proof and efficient allocation mechanisms are strongly dictatorial—i.e., they select the dictator’s preferred allocation on the entire feasible set. Thus, our results reveal the extent to which the conflict between individual incentives and other properties that may be deemed desirable (e.g., fairness, equal treatment, distributive justice) pervades resource allocation problems.     

官员规模、公共品供给与社会收入差距:权力寻租的视角

官员规模、公共品供给效率以及社会收入差距是当下社会比较关注的问题,本文试图把三个问题纳入到一个故事框架下来分析和解释。生产的进行需要官员提供资源帮扶,这需要通过雇佣下级官员来做到;当私人利益进入上级官员的收益函数时,上级官员就会促使资源的供给"人为"稀缺来设租,从而便于下级官员从生产者处收取资源租金;而资源租金的收取使得下级官员的收益高于其外部选择权收益,从而增加了下级官员职位的竞争性,又由于上级官员对下级官员职位任命权的垄断,使上级官员从下级官员处收取职位租金。分析表明,权力的设租寻租行为是造成社会收入差距出现的一个重要原因;在一个能较好限制官员关注私人收益的社会中,官员规模较小、公共品供给效率较高且因权力寻租而造成的社会收入差距较小。

Measuring fossil resource inequality—A case study for the UK between 1968 and 2000

This paper quantifies fossil resource inequalities amongst income quintiles in the UK between 1968 and 2000. It calculates a resource-based Gini coefficient using an input-output based resource allocation model.The results show that the Gini coefficient for total fossil resource consumption grew by 24% over the time period. By comparison the Gini coefficient for overall household expenditure rose by only 13%. The increase in resource inequality was prompted by the rising demand by high income quintiles for goods and services such as: “fuel and light” (heating and lighting the home), “car use” (private transportation), “recreation”, “travel” and “other services”. The analysis shows further that the Gini coefficient for “direct” fossil resources (“fuel and light” and “car use”) was lower and rose less steeply than the Gini coefficient for fossil resources embodied in other goods and services (indirect fossil resource requirements).Investigation into the drivers behind direct and indirect resource inequalities suggests a number of policy conclusions. Firstly, it is clear that policy initiatives to reduce fossil resource requirements (and the associated climate change impacts) must pay careful attention to distributional differences. Additionally, increased attention needs to be paid to the inequalities associated with indirect fossil resources consumption as well as the more visible direct resource inequalities.     

公共物品、分工演进与经济增长

在新兴古典经济学框架内,公共物品既能通过提高交易效率来促进分工演进并最终带来经济增长,也可通过改善劳动效率直接促进产出的增加,经济增长中的两难冲突发生于专业化经济和公共物品对劳动时间这一资源的争夺,资源的最终分配取决于三个重要的经济参数即专业化经济系数、公共物品的交易效率系数和劳动效率系数的大小和变化情况。文章最后从历史经验的角度来论证主要结论的正确性。     

The political economy of fiscal deficits and government production

This paper studies how disagreement over which goods government should provide affects resource allocation in the public sector. An incumbent combines pre-determined capital with labor to produce different goods in the current period, and accumulates physical and financial capital for future production. Capital-labor complementarity determines how anticipated political turnover shapes governments' choice between saving in physical capital or financial assets. Turnover tends to render the stock of physical capital for public production too low and inefficiently combined with labor. The main cost of political turnover is production inefficiency in the public sector, not a suboptimal savings level.     

Ethnic identities,public spending and political regimes

Do democracies discriminate less against minorities as compared to non-democracies? How does the dominance of an ethnic group affect discrimination under various political regimes? We build a theory to analyse such questions. In our model, political leaders (democratically elected or not) decide on the allocation of spending on different types of public goods: a general public good and an ethnically-targetable public good which benefits the majority ethnic group while imposing a cost on the other minorities. We show that, under democracy, lower ethnic dominance leads to greater provision of the general public good while higher dominance implies higher provision of the ethnically-targetable good. Interestingly, the opposite relation obtains under dictatorship. This implies that political regime changes can favour or disfavour minorities based on the ambient level of ethnic dominance. Several historical events involving regime changes can be analysed within our framework and are consistent with our results.     

Decentralisation or patronage: What determines government's allocation of development spending in a unitary country? Evidence from Bangladesh

This paper contributes to the decentralisation and distributive politics literature by empirically investigating the determinants of public expenditure at the sub-national level in Bangladesh. We argue that fragmentation in a unitary developing country may not channel higher resources to local areas. Political motives may instead play a significant role in the allocation process. Using panel data methods and a novel dataset on government's district-wise allocation of annual development expenditure in Bangladesh covering the period from 2005 to 2009, the analysis focuses on the impact of local government fragmentation and tests key political distribution models (the core voter hypothesis, the swing voter hypothesis, and the political alignment theory). The results show that local government fragmentation does not have any significant impact on public spending at the district level. However, the core vote share, local elected representative's political alignment with the ruling party, and the raw number of ministers from a district are all significantly associated with higher expenditure allocation. No evidence was found in support of the swing voter hypothesis. Overall, the findings suggest that political motives matter and that the allocation of developing spending is significantly influenced by political patronage. This may be a signficant obstacle to SDGs progress, as development spending may not be governed by resource delivery mechanisms that effectively target the poor.     

The ratio equilibrium and a voting game in a public goods economy

An economic model of the allocation process with public goods is presented. We define a concept of equilibrium and prove the existence. Next we present a voting game in which a level of the public goods to be produced is decided. We prove that the core of the voting game and the equilibria exist simultaneously, and that they coincide.     

Clubs,local public goods and transportation models: A synthesis

Clubs, local public goods, and transportation models are analyzed within a unified model. The emphasis is on the derivation of optimal allocation, pricing and the size of the sharing group. We derive the conditions under which optimal prices will yield surplus or deficit, as well as those under which competitive provision will be efficient. Given heterogeneous tastes we prove that segregation according to tastes is generally efficient although several cases where this result does not hold are also discussed. We show that the existing literature is unnecessarily restrictive and that the unified approach suggested here considerably extends the existing analysis of clubs' local public goods and the transportation problems.     

The role of social and technical excludability for the success of impure public good and common pool agreements: The case of international fisheries

We argue that international fisheries are a prime example to study the incentive structure of forming impure public good and common pool agreements. We consider a fully integrated multiple zone model, in which zones are linked through density-dependent migration. The incentive to accede to Regional Fishery Management Organizations (RFMOs) is related to multiple characteristics. Firstly, the relative patch sizes of the high seas, which is the internationally (publicly) accessible domain, compared to exclusive economic zones, which are state-owned (privately owned). This can be related to the degree of socially constructed excludability. Secondly, the intensity of fish migration between various zones, which can be related to the degree of technical excludability. Thirdly, the growth rate of the resource, which can be interpreted as the degree of rivalry, with a low (high) degree of rivalry approximating public good (common pool) features. We show that, generally, excludability reduces free-riding incentives but also the need for cooperation, a variant of the “paradox of cooperation”. Moreover, we show that the benefit-cost duality between public goods and common pool resources generally holds except for some extreme parameter values for which a low degree of rivalry fosters the success of cooperation. Finally, through a variation of the diffusion matrix, we can also analyze a closed as well as a sink-source system.     

Trade tariff,wage gap and public spending

This paper studies the interplay between wage gap and government spending in a small open economy facing a shock in trade policy. We consider a specific factor model with an export sector, which uses skilled labour, and an import-competing sector, which uses unskilled labour. We find the conditions under which there exists an inverse (direct) relation between trade liberalization (protection), which increases (decreases) the skilled-unskilled wage gap, and the level of government expenditure. We also show how either an unbalanced distribution of political bargaining power, or tariff revenue co-financing public spending may break this inverse relation. Moreover, the direct relation between tariff protection and public goods provision can be strenghtened by progressive taxation and weakened by regressive taxation.     

On the Private Provision of Two or More Public Goods

We extend the simple model of voluntary public good provision to allow for two or more public goods, and explore the new possibilities that arise in this setting. We show that, when there are many public goods, voluntary contribution equilibrium typically generates, not only too low a level of public good provision, but also the wrong mix of public goods. We also analyze the neutrality property in the more general setting, and extend a neutrality proposition of Bergstrom, Blume, and Varian (1986) .     

The impact of targeting policy on spouses’ demand for public goods,labor supplies and sharing rule

This paper studies the impact of targeted unconditional cash transfers on the spouses’ demand for public goods, labor supplies and sharing of resources. We estimate a collective labor supply model with distributional factors which is extended to include preferences over marketable public goods (including child goods). In this way, unlike previous research, we consider the impact of such transfers on the intrahousehold allocation of resources and distinguish between the labeling and recipient effects. We exploit the UK experience and find evidence in favor of the collective model with separable preferences over labor supplies and public goods. This finding implies a recipient effect and not a labeling effect of child benefits. Given the household’s unearned income, the bigger the wife’s bargaining power, the more the resources allocated to public goods (including child goods) and the wife’s private consumption. The results can be useful in the design of family policy which aims to improve the relative welfare of children within the family and alleviate any intrahousehold consumption inequalities.     

Sharing the cost of redundant items

We ask how to share the cost of finitely many public goods (items) among users with different needs: some smaller subsets of items are enough to serve the needs of each user, yet the cost of all items must be covered, even if this entails inefficiently paying for redundant items. Typical examples are network connectivity problems when an existing (possibly inefficient) network must be maintained.We axiomatize a family cost ratios based on simple liability indices, one for each agent and for each item, measuring the relative worth of this item across agents, and generating cost allocation rules additive in costs.     

Fiscal Constitutions

In this paper we examine how taxes, subsidies and the design of constitutional agendas should be regulated in order to allow for an efficient allocation of public goods and a limitation of tax distortions. We show that if public goods are socially desirable, the simple majority rule, combined with taxation constrained to majority winners or a ban on subsidies, can achieve several desirable objectives. Equal treatment regarding taxes and subsidies is undesirable. Super majority rules and equal treatment of all citizens with respect to taxes and subsidies, however, are first-best provided public goods are socially undesirable. Finally, we suggest that constitutions with amendments eliminate excessive taxation and allow treatment rules to universally improve welfare.     

The optimistic stability of the core mapping in public goods production economies

Summary We show that in a production economy with public goods and a measure space of agents an allocation belongs to the core of the economy if and only if there exists no allocation in the core of a subeconomy that blocks it.We are indebted to Yossi Greenberg for very helpful suggestions, especially concerning the introduction of this work. We would also like to thank the referee for useful suggestions. Part of this work was done while the authors were visiting CORE, Université Catholique de Louvain.

Impact of health aid in developing countries: The public vs. the private channels

This paper examines the efficient allocation of international health aid. We built a simple macroeconomic model which considers an endogenous allocation of aid mixed between the public and the private channels. We derive a non-cooperative interaction-game involving the private sector, the donor and the recipient government. We compare the equilibrium of the game to the optimal level of health aid allocation, showing a gap between both. The empirical analysis is based on the Institute for Health Metrics and Evaluation (IHME) and World Health Organization (WHO) data sets using dynamic panel data model with fixed effects (system-GMM). Our results show that health aid actually reduces adult mortality in developing countries. Furthermore, we show that the actual allocation of aid-mix between government and private channels is not health efficient and there is room for reallocation.
