Federalism,taxation, and economic growth

We present a model of endogenous growth where government provides a productive public good financed by income and capital taxes. In equilibrium, a decentralized government chooses tax policy to maximize economic growth, while a centralized government does not do so. Furthermore, these conclusions hold regardless of whether governments are beholden to a median voter or are rent-maximizing Leviathans. However, a decentralized government will under-provide public goods which benefit citizens directly, while a central government beholden to the median voter will optimally invest in such public goods.     

Federalism,distributive politics and representative democracy

We analyze federal systems of government in which local public policies are financed by general taxation. In a decentralized political system there is, in each region, a vote to elect a local representative while in a centralized political system a single representative is elected by a federal vote. It is shown that under decentralization, voters strategically elect liberal representatives so as to nullify any element of cooperation between representatives in the decision-making stage. Thus, there is a trade-off between the budgetary externality and a "policy closer to the people", but the democratic choice is biased towards decentralization.     

Fiscal centralization versus decentralization: Growth and welfare effects of spillovers, Leviathan taxation, and capital mobility

This paper develops an endogenous growth model with spillovers of public goods, Leviathan taxation, and mobile capital to examine the relative merits of centralized and decentralized fiscal systems for economic growth and social welfare. We show that a decentralized system dominates a centralized system in terms of economic growth; however, the difference in social welfare between a decentralized and a centralized system is non-monotonic and displays a hump-shaped relationship with respect to capital mobility. Since higher capital mobility induces stronger tax competition, this finding implies that there is an optimal degree of tax competition; some tax competition is desirable, but fierce tax competition may be harmful. We also show that there is a critical level of spillovers of public goods above which centralization dominates decentralization in terms of social welfare, as in previous studies; however, if spillovers are below this critical level, capital mobility also matters in the welfare comparison between centralized and decentralized systems.     

Fiscal decentralization and centralization under a majority rule: A normative analysis

In his seminal work on fiscal federalism, Oates [Oates, W., 1972. Fiscal Federalism. Harcourt Brace Jovanovich, New York, NY] addressed the so-called Decentralization Theorem, which states that, if such factors as scale economies and spillovers are left out of consideration, a decentralized system is always more efficient than a centralized system for supplying local public goods. Based on his analytical framework, we show that a decentralized system may at times be inferior in efficiency to a centralized system under a democratic decision rule (Proposition 2). An intuition for this result is that, under majority rule, a majority may choose an extreme policy in a local district that best matches its own preference but ignores the interests of minorities. In some cases, such disregard of minority taste may result in a considerable loss of efficiency. If instead some moderate policies are chosen through voting in an integrated constituency, then the interests of minorities could be better served to some extent. As a result, centralization would improve social welfare.     

Centralized and decentralized provision of public goods

We model the trade-off between centralized and decentralized decision making on the provision of local public goods. Decisions are influenced by spillover effects and differences in jurisdictional size. Centralized decisions are made in a legislature of locally elected representatives, and this creates a conflict of interest between citizens in different jurisdictions. The legislature can be self-interested or benevolent and this can result in either efficient, excessive, or misallocative provision of public goods. The form of centralized decision making has a significant influence on the incentives for centralizing decision making.     

Public housing units vs. housing vouchers: Accessibility,local public goods,and welfare

We develop a general equilibrium model of residential choice and study the effects of two housing aid policies, public housing units and housing vouchers. Land is differentiated by both residential accessibility and local public goods, and the provision levels of local public goods are determined by property tax revenues and neighborhood compositions. Households differ in their incomes and preferences for local public goods. Housing aid policies are financed by general income taxes. We discuss how the location of public housing units is a fundamental policy variable, in addition to the numbers and sizes of units, and argue that vouchers not only cause less distortion for social welfare compared to public housing, but may also improve overall welfare.     

Non-cooperative pollution control in an inter-jurisdictional setting

This paper examines various circumstances under which decentralized pollution policies can be efficient both in federal settings and in multi-region settings with labor mobility. We consider a model in which pollution control policies are set by regional governments non-cooperatively and pollution damages are borne by the residents of all regions. We characterize the efficiency of pollution policies, and of population allocation among regions, in a variety of scenarios, including when pollution policies are enacted before interregional transfers are determined by the federal government and before migration occurs; when migration decisions are taken before policy decisions; in the absence of a central government if regional governments can make voluntary interregional transfers; when decisions over pollution control policies are followed by voluntary contributions by regions to a national public good; when regions can commit to matching the abatement efforts of each other; and when regions can commit to specific levels of abatement contingent on the emissions of other regions not exceeding some maximum level.     

谈政府集中采购模式下政府集中采购机构与招标代理中介机构的利与弊

政府采购就是指国家各级政府为从事日常的政务活动或为了满足公共服务的目的,利用国家财政性资金和政府借款购买货物、工程和服务的行为。我国的政府采购制度将采购行为划分为集中采购和分散采购。集中采购的代理行为是政府采购流程中的关键环节。     

Federal grants and the flight to the suburbs

Migration to the suburbs is a long-standing problem for cities in the United States. A central question in the literature is whether the improvement in public goods and services in the central cities will stop the flight to the suburbs. We would expect that if cities offer better services, it would persuade affluent residents to stay in the city. We find, paradoxically, that even if these reforms are exclusively financed by the federal or state government, and even if the grant money indeed goes towards improving the quality of public goods and not towards redistribution, the city may end up with more flight to the suburbs.     

Green supply chain decision modeling under financial policy,with or without uniform government emission reduction policy

This paper investigates green supply chain decision making under different government policies. The problem is explored under centralized and decentralized scenarios. We verified the advantages of simultaneous government implementation of financial and uniform manufacturing policies and found that, with increased public awareness of environmental protection, government subsidy also increases: when environmental protection awareness is sufficiently strong, the government does not have to set uniform policy. Finally, by parametric and numerical analyses, our research identified the conditions under which social welfare is maximized. The results facilitate scientific policy development and provide a reference for promoting green supply chain operations.     

Pareto improving interventions in a general equilibrium model with private provision of public goods

Most of the literature on government intervention in models of voluntary public goods supply focuses on interventions that increase the total level of a public good, which is considered to be typically underprovided. However, an intervention that is successful in increasing the public good level need not benefit everyone. In this paper we take a direct approach to welfare properties of voluntary provision equilibria in a full blown general equilibrium model with public goods and study interventions that have the goal of Pareto improving on the voluntary provision outcome. Towards this end, we study a model with many private goods and non-linear production technology for the public good, and hence allow for relative price effects to serve as a powerful channel of intervention. In this setup we show that Pareto improving interventions generally do exist. In particular, direct government provision financed by “small” , or “local” , lump-sum taxes can be used generically to Pareto improve upon the voluntary provision outcome.     

Tax Competition and Revelation of Preferences for Public Expenditure

This paper considers a federal country composed of local jurisdictions that differ in their inhabitants' tastes for public goods, and which finance local public expenditure through a source-based tax on capital income. The taste for public goods is the private information of local governments. The central government seeks an optimal policy, in which grants to local governments are conditioned on local tax rates. The uninformed central government seeks both to allocate capital efficiently among jurisdictions, and to induce jurisdictions to provide an efficient mix of private and public consumption. It is shown that there persist at this constrained optimum both some misallocation of capital and some violation of the Samuelson rule for optimal public good provision in every jurisdiction.     

Voting on devolution in a federal country with a bicameral national system

We analyse voting on the devolution of the responsibilities for the provision of public goods to local governments in a federal country, with a bicameral national legislature. In our set-up, devolution means a constitutional fiscal reform which reduces federal public expenditure on a local public good, and simultaneously increases the transfers received by regions, via a tax-sharing mechanism. This allows the regions to provide a greater amount of a local public good which can compensate for the reduction of that provided upon a federal basis. We show under which conditions such a devolution reform is adopted or rejected.     

The political economy of fixed regional public expenditure shares with an illustration for Belgian railway investments

Many local public goods are allocated by federal governments using fixed regional shares: every region is entitled a fixed share of the total budget for a particular type of public good. This paper explores two characteristics of this type of allocation. First, it shows that this type of allocation is relatively efficient as it puts a strict budget constraint on the decisive region. Second, we show that these fixed shares can be an equilibrium of different legislative bargaining processes. The working of the fixed sharing rules is illustrated for the allocation of railway investments in Belgium.     

基于渠道竞争的双渠道供应链低碳协调策略

针对由一个制造商和一个零售商构成的双渠道供应链,将渠道竞争和产品的低碳性能引入消费者的非线性需求中,通过构建制造商为主导者的Stackelberg博弈模型,对比分析了分散决策和集中决策下的最优定价、碳排放水平和成员利润,并采用价格折扣-成本分摊契约实现了供应链的协调。研究结果表明:在分散决策和集中决策两种情况下,渠道竞争程度的增加均会造成碳排放水平、供应链利润和消费者效用的降低;集中决策下的直销价格大于分散决策下的直销价格,集中决策下的零售价格小于分散决策下的零售价格。最后通过算例验证了以上结论和协调机制的有效性。     

'Public Goods' from the Market

In the mounting criticism of 'government failure', a role for government is stubbornly argued by statist-minded economists on the ground that only government can supply public goods - from defence to (some) research (p. 34). Frank van Dun of the University of Ghent argues that public goods have the same disadvantages of monopoly, restriction of choice, confiscation by taxation, pressure group distortion, as non-public goods unnecessarily supplied by government. Moreover, technical progress will make it possible to supply more public goods in the market by creating separable benefits that can be financed by pricing.

The Role of Symmetry between the Revenue and the Expenditure Side of the Government Budget in the Debate about the Potential Negative Effects of Tax Competition

The effects of capital tax competition are reconsidered in this paper incorporating the argument that the expenditure structure of public budget should reflect its revenue structure. The paper offers a small open economy model where capital and labour tax revenues are used exclusively on the provision of public inputs. It is shown that if the revenue side of the government budget exactly matches the expenditure side that is if industrial public goods are financed by both private production factors with the weights reflecting the contributions of public inputs to the private factor productivity then public inputs are provided optimally even in the presence of tax competition.     

Mexican agriculture in economy-wide policy: Latitude for special treatment

The Mexican economy has gone through radical transformations in the past 7 years which have been reinforced during the Salinas administration. From the early 60s up to the mid-eighties, Mexico tended to pursue an inward-oriented development strategy. Those economic policies affected negatively the agricultural sector, especially through the indirect effects of the macroeconomic policies. The paper analyzes the role of the agricultural sector in the process of liberalization. It is argued that strategies to develop agriculture must also focus on policies outside the sector, that the level and rate of economic growth is particularly sensitive to investment in public goods, and that an over-investment in these goods might be justified if it induces rural households to engage in political activity that will prevent a movement towards the old policy regime once an economic crisis is resolved.     

Decision analysis and coordination of dual supply chain with retailer's offline return service and online reviews

Based on the centralized and decentralized decision-making cases, this study constructs a dual-channel supply chain game model that considers offline return service and online reviews, and explores the pricing decisions and benefits of supply chains under the dual influence of return service level and online reviews. The impact of return rate, return service level and perceived quality of online reviews on optimal supply chain decisions and profits are further analyzed. Finally, considering the phenomenon of double marginalization in the supply chain, this study coordinates the supply chain based on the benefit-sharing contract coordination model to achieve Pareto improvement. The research shows that: The manufacturer's optimal wholesale price, the optimal online selling price and the retailer's optimal offline price are positively correlated with the perceived quality of online reviews and the level of return service. Compared with the return service level, the perceived quality of online reviews has a greater impact on the overall profit of the supply chain. Under the dual influence of the perceived quality of online reviews and the level of return service, the supply chain profit in the centralized model is better than that in the decentralized model. The coordination model can effectively coordinate the supply chain. Moreover, when the sharing ratio of manufacturers is obviously lower than that of retailers, the coordination effect is better at this time.
