Strategic state-level environmental policy with asymmetric pollution spillovers

This paper examines the strategic behavior of state-level utility regulators in the context of the federal tradable emissions permits market when state-to-state pollution spillovers are asymmetric. Strategic behavior is possible because a state’s environmental policy indirectly affects the price of permits and, therefore, abatement in other states. We show that the optimal pollution penalty is comprised of two parts: (i) a Pigouvian tax, adjusted for state-to-state spillovers; and (ii) an optimal tariff designed to improve the terms of trade in permits. Generally, abatement costs are not minimized and the outcome is Pareto inefficient, regardless of the size of the market.     

License scheme: an optimal waste management policy under asymmetric information

A system requiring a waste management license from an enforcement agency has been introduced in many countries. A license system is usually coupled with fines, a manifest, and a disposal tax. However, these policy devices have not been integrated into an optimal policy. In this paper we derive an optimal waste management policy by using those policy devices. Waste management policies are met with three difficult problems: asymmetric information, the heterogeneity of waste management firms, and non-compliance by waste management firms and waste disposers. The optimal policy in this paper overcomes all three problems.     

Strategic pollution control under free trade

This paper designs a reciprocal dumping model to address the control of industrial pollution between two trading partners. Firms generate transboundary pollution from production and environmental taxes represent the pollution control instrument. We ask whether environmental taxes implemented in a non-cooperative setting are more stringent than the globally efficient level. Relative to the globally efficient case, we find in the linear Markov Perfect Nash Equilibrium (MPNE) context that the tax rate for both countries is smaller and individual emissions are larger. However, these results may not hold in the non-linear MPNE case depending on market structure and environmental conditions. Unlike the symmetric equilibrium case, the tax rates are always discontinuous under asymmetric MPNEs. The asymmetric equilibrium scenario can give rise to higher individual payoffs relative to the symmetric equilibrium case.     

Optimal policy for environmental goods trade in asymmetric oligopolistic eco-industries

In this paper, we examine the optimal structure of an environmental tax to pollution, a production subsidy to a domestic eco-industry, and an import tariff on environmental goods (EGs) in a two-country model where the home country imports EGs from the foreign country. Home and foreign firms that produce EGs engage in Cournot competition. We then assume that the number of the home local firms which produce EGs is constant, but that of the foreign firms is variable. Our main findings are as follows: (I) The optimal environmental tax level may be lower than the Pigouvian level even if the tax has a positive impact on the output of EGs produced by a domestic firm. (II) The optimal tariff level may be positive when the country implements the first best policy combination in a closed economy regarding the environmental tax and the subsidy. (III) The optimal subsidy level may be positive, and then the subsidy may be substitutive for the import tariff on EGs.     

International monetary policy coordination under asymmetric shocks

This paper analyzes whether international monetary policy coordination is the best response to economic interdependence. The paper develops a macroeconomic model in which countries show different preferences regarding objectives when faced with asymmetric disturbances and analyzes in strategic terms how monetary policy can deal with real, monetary, and supply-side shocks. It further shows how the desirability of monetary policy coordination depends on the presence of asymmetric shocks and also on the nature of disturbances, the channel of transmission, and the asymmetry of preferences. Finally, the paper derives the conditions under which monetary policy coordination proves to be desirable.     

Learning about compliance under asymmetric information

Over time, inspection agencies gather information about firms’ pollution levels and this information may allow agencies to differentiate their monitoring strategies in the future. If a firm is less successful than its peers in reducing emissions, it faces the risk of being targeted for increased inspections in the next period. This risk of stricter monitoring might induce high-abatement cost firms to mimic low-abatement cost firms by choosing lower emission levels, while the latter might try to avoid being mimicked. We explain firms’ compliance decisions and the inspection agency's monitoring strategy by means of a signaling game which incorporates dynamic enforcement and learning. Interestingly, we show that the ongoing signaling game between firm types might lead to firms over-complying with the emission standard.     

Stackelberg leadership under symmetric and asymmetric information

This Paper considers the types of pre-committments that a first moving incumbent may make when information is symmetric, and when it is asymmetric. The model contains as a special case the familiar model of Stackelberg leadership, but also shows the circumstances under which more complex strategies are optimal for the incumbent.     

Incentives in academic tenure under asymmetric information

This paper examines the incentives in academic tenure under asymmetric information where neither types nor actions of the agents are observable. The different contractual forms are compared, including short-term non-tenured contract and tenure contract with or without probationary period. It is shown that tenure track may help reduce information rent for the department in the situation where a smaller portion of high productive researchers are entitled to undertake very costly and time-consuming research project with a high potential value. However, when the probationary period cannot efficiently screen out the low productive researchers, providing both short-term non-tenured contract and tenure contract without probationary period or merely providing short-term non-tenured contract will be more likely taken by department. Therefore, the coexistence of different contractual forms in higher educational system, including the growing use of non-tenure track in some academic sectors can be economically explained.     

Production and financial policies under asymmetric information

We propose an extension of the standard general equilibrium model with production and incomplete markets to situations in which (i) private investors have limited information on the returns of specific assets, (ii) managers of firms have limited information on the preferences of individual shareholders. The extension is obtained by the assumption that firms are not traded directly but grouped into ‘sectorial’ funds. In our model the financial policy of the firm is not irrelevant. We establish the existence of equilibria and discuss the nature of the inefficiencies introduced by the presence of asymmetric information. We also illustrate the properties of the model in three simple examples. We would like to thank Alberto Bisin, Armando Dominioni, Piero Gottardi, Tito Pietra, Paolo Siconolfi, and an anonymous referee for useful suggestions and comments.     

Industry structure and trade policy under fluctuating import prices

When subsidies and tariffs are applied to imports with fluctuating prices, it is shown that the output response of domestic producers depends on market structure and their attitude toward risk. The domestic industry response is contrasted under two types of market structure, a monopoly and a competitive industry. Some unanticipated results suggest caution in the implementation of trade policy.     

Importing under trade policy uncertainty: Evidence from China

This paper empirically explores the adjustment of imports to reductions in trade policy uncertainty (TPU), taking into account that firms may face large sunk costs when purchasing foreign goods. We investigate how product-level Chinese imports react to tariff binding arising from China's accession to the WTO, by distinguishing both country-related and firm-related margins. Our main results suggest that a decline in TPU allows access to a greater variety of foreign goods, that are also associated with higher quality. At the same time, tariff binding leads more Chinese producers and trade intermediaries to start importing, thus allowing a greater number of firms and consumers to enjoy potential gains from imports. Finally, we document heterogeneous TPU effects across firms with different ownership, as well as across products with different end use, revealing interesting insights into the context of global value chains.     

Reorganization strategies and securities valuation under asymmetric information

This paper examines optimal reorganization strategies during financial distress and securities valuation under asymmetric information. We model strategic interactions between debtholders and equityholders in a game-theoretic setting that can accommodate the varying bargaining powers of the two claimants. Two reorganization strategies are considered: Chapter 11 (debt–equity swap) and private workout (strategic debt service). Using Chapter 11 as a costly state verification device, we characterize in equilibrium which firms choose Chapter 11 and which choose private workout. In particular, we show how the bank's belief about the type of firm evolves by observation of reorganization strategies. We also derive closed-form solutions to both the equity and debt valuation problems under asymmetric information and show that credit spreads increase with the degrees of asymmetric information.     

Factor income taxation and growth under asymmetric information

This paper studies the growth effects of factor income taxation on capital and labor in an endogenous growth model with overlapping generations. Capital accumulation in our model takes place through credit-financed investments in a market with asymmetric information between lenders and borrowers. We show that, in the presence of asymmetric information, capital income taxation worsens the adverse selection problem in the credit market, which in turn introduces an additional adverse effect on growth. In so doing, our analysis provides a new argument in favor of a lower (higher) capital (labor) income taxation in funding public expenditures.     

Interregional redistribution and budget institutions under asymmetric information

Empirical evidence from the U.S. and the European Union suggests that regions which contribute to interregional redistribution face weaker borrowing constraints than regions which benefit from interregional redistribution. This paper presents an argument in favor of such differentiated budget institutions. It develops a two period model of a federation consisting of two types of regions. The federal government redistributes from one type of regions (contributors) to the other type (recipients). It is shown that a fiscal constitution with lax budget rules for contributors and strict budget rules for recipients solves the self selection problem the federal government faces in the presence of asymmetric information regarding exogenous characteristics of the regions.     

Joint implementation under asymmetric information and strategic behavior

Joint Implementation (JI) under the Framework Convention on Climate Change means that countries could partly offset their national abatement commitments by investing in CO₂ abatement projects abroad. JI is introduced as a mechanism for achieving a certain global abatement target less costly by separating the commitments from the implementation of measures. This paper studies the design of a JI contract when the investor has incomplete information about the foreign firm which carries out the JI project (the host). Asymmetric information leads to a decrease in the potential cost savings from JI. Furthermore, private information held by the potential host firm could give the firm a significant positive utility of participating in JI projects. The possibility of being a host for a JI project in the future can prevent potential host firms from investing in profitable abatement projects today. The paper analyzes the impact on emissions of CO₂ of strategic behavior among potential hosts for JI projects.     

Multi-player contests with asymmetric information

We consider imperfectly discriminating, common-value, all-pay auctions (or contests) in which some players know the value of the prize, others do not. We show that if the prize is always of positive value, then all players are active in equilibrium. If the prize is of value zero with positive probability, then there is some threshold number of informed players such that if there are less, all uninformed players are active, and otherwise all uninformed players are inactive.     

Core convergence with asymmetric information

We analyze the ex ante incentive compatible core for replicated private information economies. We show that any allocation in the core when the economy is replicated sufficiently often is approximately Walrasian for the associated Arrow–Debreu economy.     

Strategic R&D policy under vertically differentiated oligopoly

In this paper strategic R&D policy is analysed, where a high-tech firm and a low-tech firm compete in a third country with vertically differentiated ( high-quality and low-quality ) products. If the product market is under price competition, the high-tech (low-tech) firm's government has an incentive to tax (subsidize) its domestic firm's product R&D activities. If the product market is under quantity competition, the results are opposite: an R&D subsidy (tax) incentive for the high-tech (low-tech) firm's government; and the high-tech firm's government always gains in the R&D policy game, in contrast to the standard prisoner's dilemma result of the R&D policy literature.
