Leadership and motivation for public goods contributions

Results from a leader–follower public goods game are presented. An individual, when randomly selected to make a contribution knowing others will observe the selection, gives more than in the simultaneous‐move public goods game. Followers adopt a quasi‐matching strategy where they systematically donate less than the leader, but contribute more when the leader does and contribute less when the leader free rides. The net result is increased provision of a public good when contributions are sequential. The results highlight that psychological preferences, rather than solely social preferences, can explain behavior.     

Decentralization and international tax competition

This paper models tax competition between two countries that are divided into regions. In the first stage of the game, the strategy variable for each country is the division of a continuum of public goods between central and regional government provision. In the second stage, the central and regional governments choose their tax rates on capital. A country's decentralization level serves as a strategic tool through its influence on the mix of horizontal and vertical externalities that exists under tax competition. In contrast to standard tax competition models, decentralizing the provision of public goods may improve welfare.     

Privatization of state holding corporations

Many countries have privatized part of their state holding corporations in recent years. However, the literature on this issue has analyzed mainly the privatization of uniproduct public firms. We consider a state holding corporation with two plants that may produce complement or substitute goods. Assuming that private firms are more efficient than the state holding corporation we find the following: If the marginal cost of the state corporation is low, it is not privatized either if goods are substitutes or if they are complements. However, if the marginal cost of the state corporation is high the two plants of the state holding corporation are sold to a single private investor if goods are complements, and to different investors if goods are substitutes. If goods are close substitutes and the marginal cost of the state corporation takes an intermediate value only one plant is privatized. We extend the model to consider that firms are equally efficient, that they face quadratic cost functions and that there are n uniplant private firms producing each good. We find two differences with the previous result: The government never privatizes just one plant of the state corporation, and when goods are complements the two plants of the state corporation are sold to different investors if n is high.     

Public or Private Sector Wage Leadership? An International Perspective*

Whether a government acts as a wage leader, placing pressure on private‐sector wages (more open to competition), or whether it plays a passive role and merely follows wage negotiations in the private sector, there are important implications for macroeconomic development, particularly in small open economies and/or countries that are members of a monetary union, such as those of the European Monetary Union. With the notable exception of the case of Sweden, opinion on this issue is still divided. In this paper, we look at public‐ and private‐sector wage interactions from an international perspective (18 OECD countries). We focus on the causal two‐way relationship between public and private wage setting, confirming that the private sector, on the whole, appears to have a stronger influence on the public sector, rather than vice versa. However, we also find evidence of feedback effects from public wage setting, which affect private‐sector wages in a number of countries. When the private sector takes the lead on wages, there are few feedback effects from the public sector, while public wage leadership is typically accompanied by private‐sector feedback effects.     

Optimal trade policy in tariff games with inside money

We construct a bilateral trade model incorporating two physical goods and a financial asset (inside money) to discuss the optimal trade policy that countries would choose to maximize their respective utilities. In this Nash tariff game, the trade of physical commodities only occurs geographically across countries, and the trade of inside money allows for intertemporal allocation of consumptions. When the preferences, present and future endowments for each country are given, according to our numerical analysis, trade surplus or deficit (inside money) and optimal tariff rates are endogenously determined when general equilibrium conditions hold. One country may purchase inside money to shift current consumption to the future, and the other may be willing to issue inside money for smoothing its consumptions in two periods. This imbalance trade contradicts traditional trade models which imply a balanced trade policy. We further find that the price of inside money as an implied interest rate also is determined by the trade intervention policies.     

A Dynamic Tiebout Theory of Voluntary vs. Involuntary Provision of Public Goods

This paper considers a dynamic model of Tiebout-like migration between communities that utilize distinct allocation procedures for public goods. At issue is whether voluntary or compulsory procedures are more likely to prevail over time. We model infinitely lived individuals who make repeated, sequential location decisions over one of two communities. Each community uses a distinct mechanism for allocating public goods. The first is one in which contributions are given voluntarily by the citizenry of the community. The second is a compulsory scheme by which individuals are taxed proportionately to wealth with the tax determined by a majority vote. Opportunities to accumulate wealth exist via accumulation of public capital.
The Markov Perfect equilibria of the dynamic game are studied. Our main result shows that when accumulated wealth converges to a steady state, individuals' locational choices eventually "select" the involuntary provision mechanism. This holds despite the fact that unanimous location in the voluntary provision community may in many cases remain as a Nash equilibrium of the static game each period. We also describe conditions under which voluntary provision survives. These conditions require that accumulation of capital fails to decrease wealth dispersion over time. The results are shown to be consistent with findings relating inequality to school choice.     

The Formateurs’ Role in Government Formation

Following an election, Heads of State typically choose a formateur to report back a prospective government by some deadline. If this formateur fails then another party leader is chosen on the same terms. We model this mechanism as a bargaining game, in which a single party leader has exclusive access to the Head of State, but does not have a monopoly on making proposals. We characterize the unique equilibrium of the game in which all parties are symmetric and parties split a fixed-size pie. We also show that supra-minimal governments may form when parties are asymmetrically sized: a result consistent with the evidence on government formation in countries which use a formateur mechanism. We are grateful to Maria Montero, Rick Thomas and Paul Warwick for valuable conversations, and to seminar participants in UBC and Warwick.     

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.     

Competition Policy as Strategic Trade with Differentiated Products

The paper analyzes how countries use competition policy as a tool for strategic trade. In the model, two countries export to a third country. Each exporting country is endowed with a set of differentiated products. Each government chooses the number of exporters for its country and the products that each exporter sells in the first period, and a tax policy in the second period. Firms choose prices or quantities independently in the third period. In the unique subgame‐perfect equilibrium, both countries group all their products within a single firm—the “national champion policy.” We study the implication of different assumptions about the timing of the game.     

FREE TRADE NETWORKS WITH TRANSFERS*

We investigate the network of bilateral free trade agreements (FTAs) in the context of a network formation game with transfers. In a previous paper we showed that without international transfers countries with different industrialization levels cannot sign an FTA, so that the global free trade network, in which every pair of countries signs an FTA, is not in general pairwise‐stable. In this paper we show that, even if the world consists of fairly asymmetric countries, the global free trade network is pairwise‐stable when transfers between FTA signatories are allowed. Moreover, it is a unique pairwise‐stable network unless industrial commodities are highly substitutable.     

Redistribution and Provision of Public Goods in an Economic Federation

This paper concerns redistribution and public good provision in an economic federation with two levels of government: a local government in each locality and a (first mover) central government. Each locality is characterized by two ability‐types, and the ability‐distribution differs across localities. The central government redistributes via a nonlinear income tax and a lump‐sum transfer to each local government, while the local governments use proportional income taxes and provide local public goods. We show how the redistributive role of taxation is combined with a corrective role, and how the central government can implement the second best resource allocation.     

Endogenous timing and income inequality in the voluntary provision of public goods: Theory and experiment

This study theoretically and experimentally investigates the effects of income inequality on donors' decisions regarding timing choices and contributions to public goods when contribution timing is endogenously chosen by contributors. To this end, we use the conventional voluntary provision models of Warr (1983) and Bergstrom, Blume and Varian (1986), with Cobb–Douglas preferences augmented with a two-stage game of Hamilton and Slutsky (1990). The following results were obtained and experimentally confirmed. First, when the distribution of income is extremely unequal, donors are indifferent between the simultaneous and sequential moves in the contribution game. Second, as income inequality is decreased, the simultaneous-move contribution game is likely to emerge because every donor prefers to act as a leader. Nevertheless, a higher-income donor may also prefer to act as a follower without specific social preferences and uncertainty regarding the quality of public goods. Third, most theoretical predictions regarding timing decisions are supported in our laboratory experiment, provided that the participants had enough time to learn the consequences of their timing choices.

Product Market Integration and Union Collusion

This paper investigates the effects of product market integration on the incentives and scope for union collusion across borders. In the absence of binding agreements, the impact of this process on the unions’ willingness to collude depends both on the degree of product market integration and on the degree of substitutability among traded goods. Where trade barriers across countries are relatively low, implicit cross‐border collusion among unions is more difficult the more integrated are product markets and the less substitutable are traded goods.     

Efficient Equilibria in the Voluntary Contributions Mechanism with Private Information

We characterize generally the Bayesian Nash equilibria of a voluntary contributions public goods game for two consumers with private information.The two consumers simultaneously make voluntary contributions to the public good, and the contributions are refunded if the total falls short of the cost of the public good. Several families of equilibria (step‐function, regular and semi‐regular) are studied. Necessary and sufficient conditions for regular and semi‐regular equilibrium allocations to be interim incentive efficient are derived. In the uniform distribution case we prove (i) the existence of an open set of incentive efficient regular equilibria when the cost of production is large enough and (ii) the existence of an open set of incentive efficient semi‐regular equilibria when the cost of production is low enough. Step‐function equilibra are proved to be interim incentive inefficient.     

Market Entry Regulation and International Competition*

We analyze a non‐cooperative two‐country game where each government decides whether to allow free market entry of firms or to regulate market access. We show that a Pareto‐efficient allocation may result in equilibrium. In particular, if the cost difference between home and foreign production is “significant,” production will be located in the cost‐efficient country exclusively; and if this cost difference is even “substantial,” the induced allocation is also Pareto efficient. Only if the cost difference is “insignificant,” production may take place in both countries and the allocation is inefficient.     

Group size paradox and public goods

In an economy with voluntarily provided public goods and private product varieties, and a general class of CES preferences, it is shown that aggregate public good contribution follows an inverted-U pattern with respect to group size when private and public goods are substitutable in preferences. With complementarity, however, aggregate provision grows monotonically with group size.     

HOUSING OVER TIME AND OVER THE LIFE CYCLE: A STRUCTURAL ESTIMATION

We construct a model of optimal life‐cycle housing and nonhousing consumption and estimate the elasticity between the two goods to be 0.487. The estimate is robust to different assumptions of housing adjustment cost, but sensitive to the choice of sample period and the degree of aggregation of data moments. We then conduct experiments in which house prices and household income fluctuate. Compared with the benchmark, the impact of the shocks on homeownership rates is reduced, but the impact on nonhousing consumption is magnified when housing service and nonhousing consumption are highly substitutable or when the house selling cost is sizable.     

STRATEGIC EQUILIBRIA IN A MODEL OF ECONOMIC GROWTH WITH INPUT INTERDEPENDENCE

Two countries face a strategic interdependence in producing intermediate goods. Producing these intermediate goods requires both domestic capital and another imported intermediate good. Individually, both economies determine a balanced growth path by taking into account this interdependence in different grades of awareness. By allowing for strategic interactions in the analysis, we adapted a two‐agent dynamic setting and find an interior Markov perfect equilibrium as well as an open‐loop equilibrium reflecting these different degrees of reaction. We find that main results resemble each other but growth rates will be higher when strategies are dynamically updated.     

Effect of an audience in public goods provision

This paper investigates a novel public goods game where contributions to the public goods require effort that is observable. When the players are observed, they exert more effort to contribute to the public goods, and free-riding diminishes significantly compared to the no observer case. These effects are absent when no effort is required in order to contribute to the public goods. Furthermore, in the presence of an audience, the contributions to the public goods do not diminish when the game is repeated in the effort-required environment. Being observed does not affect the performance of the players if there is no strategic aspect of the game, in other words, when they play a private goods game. These results indicate that an individual wants to avoid appearing lazy when her effort helps the society.
