Environmental R&D and privatization in a mixed duopoly market

The study examines strategic environmental research and development (ER&D) under environmental tax in a mixed duopoly and further analyzes the impact of privatization on it. We show that the environmental tax may not necessarily promote the private (or public) firm's ER&D, and the relative ER&D performance between firms depends on the public firm's environmental attitudes and the tax rate. When the public firm cares much for environment, it can be used as an instrument to correct the private firm's underinvestment (or overinvestment) in ER&D. Moreover, privatization can (cannot) raise both firms' ER&D simultaneously if the tax rate is high (low).     

基于成本差异的最佳贸易与产业政策选择

本文讨论了存在成本差异的第三国市场模型的最佳贸易与产业政策选择问题，讨论了社会成本和私人成本、本国和外国成本差异情况下的Cournot竞争和Bertrand竞争的情况。本文发现，在Cournot竞争下，政府首先行动时，当政府基金影子价格低于4／3时，政府对出口进行补贴，并且本国越有成本优势，补贴越高，补贴的利润转移效应越大；当政府基金影子价格高于4／3时，政府对出口征收出口税，且本国越有成本优势，征税越多。在Bertrand竞争下，当政府先行动时，对出口征收出口税；当政府后行动时，对出口进行补贴。当本国企业具有劣势时，事后补贴是最佳政蓑。     

Environmental regulations in private and mixed duopolies: Taxes on emissions versus green R&D subsidies

In this article, we compare two kinds of environmental regulations—emissions taxes and green R&D subsidies—in private and mixed-duopoly markets in the presence of R&D spillovers. We show that a green R&D subsidy is better (worse) than an emissions tax when the green R&D is efficient (inefficient), irrespective of R&D spillovers, whereas the existence of a publicly owned firm encourages the government to adopt a subsidy policy. We also show that the optimal policy choice depends on R&D efficiency and spillovers. In particular, when green R&D is inefficient and the spillover rate is low (high), the government should choose an emissions tax and (not) privatize the state-owned firm. When green R&D is efficient, however, an R&D subsidy is better, but a privatization policy is not desirable for society, irrespective of spillovers.     

PARTIAL PRIVATIZATION UNDER ASYMMETRIC MULTI‐MARKET COMPETITION

Under the assumption that a public firm provides goods or services to two markets and that a private firm provides goods or services to one market only, this study examines whether public firms should be privatized. It also investigates how the production quantity of a private firm changes when its degree of privatization increases. We find that when the market share of a duopoly market is large (small), partial privatization (nationalization) is socially preferable. We also find that the quantity produced by the private firm does not always increase along with the degree of privatization.     

Mineral Taxation in Jamaica: An Oligopoly Confronts Taxes on Resource Rents — and Prevails

Abstract . The reallocative effects on bauxite production in Jamaica following the imposition of an ad valorem tax in 1974 are considered. The international aluminum industry, being both vertically and horizontally integrated, evolved a successful strategy of time-phasing bauxite production capacity worldwide. The non-neutral tax not only made Jamaican bauxite uncompetitive with the output of other producers but also eroded the cost differential between bauxite and alternative sources of aluminum ore. The study claims that the consequences of the tax have been disastrous, and it argues that the ad valorem tax on the recovered ore must be replaced by some form of a profits-based tax.     

Mixed Duopoly with Subcontracting

Existing literature on mixed oligopoly focuses on competition among different types of firms but ignores their possible cooperation. We allow cooperation between a public firm and a private firm through subcontracting in a Hotelling mixed‐duopoly model. We find that when subcontracting is possible, the equilibrium without subcontracting is not socially optimal because subcontracting can lower total production costs. And if both firms engage in subcontracting, the existence of a public firm can guarantee the first best equilibrium, whether it is the low‐cost firm or not. But when a private firm is the low‐cost firm, it is more profitable for it to choose vertical foreclosure. And the consequent equilibrium is not socially desirable anymore.

Strategic Interaction between Governments and Investors under Privatization Programs

This article analyses the strategic moves of governments and investors under privatization programs in a game‐theoretic context. In sequential‐move games of both perfect information and incomplete information, the best response of the strategic investors to observing a slow pace of privatization is to have a low participation in economic activity because of concerns over public policy credibility. This is true even if the government chooses to randomize its action to send mixed signals to the investors while adopting a slow pace of privatization for budgetary reasons. However, the outcome is Pareto inferior to a situation of phased but fast implementation of privatization programs and high private‐sector participation under plausible assumptions.

The impact of private benefits on institutional ownership change: evidence from markets with different sentiments

This study investigates the relationship between private benefits and institutional ownership change in markets characterized by different investors’ sentiments. High-sentiment markets tend to overvalue a firm and thereby offer institutional investors a chance to sell shares and profit from overvaluation by forgoing the private benefits otherwise obtainable. Empirical analysis of ownership data from 1990 to 2008 reveals that, in high-sentiment markets, institutional investors sell more shares low in private benefits (dual-class firm share) than shares high in private benefits (non-dual-class firm share). In contrast, firm insiders, who consume significant private benefits in both dual-class and non-dual class firms, sell more dual-class firm shares in both high- and low-sentiment markets. Their ownership disposition is more likely driven by the need for diversification. Subsample analyses show that public pension funds drive the market-sentiment-related change of institutional ownership.     

Privatisation and vertical integration under a mixed duopoly

This paper analyses the privatisation of public firms when private firms may be vertically integrated with their suppliers. We consider a mixed duopoly with a vertically integrated public firm. The private firm bargains the price of the input with its supplier if they are not vertically integrated. We find that for a given bargaining power of the private firm, it vertically integrates with its supplier if goods are weak substitutes. We also find that there is less vertical integration in the mixed duopoly than in the private duopoly. Finally, in general, the public firm is privatised when goods are close substitutes and the bargaining power of the private firm is low enough.     

Environmental taxes in a differentiated mixed duopoly

Beladi and Chao (2006) and Bárcena-Ruiz and Garzón (2006) considered the role of environmental policy on the decision whether to privatize a public firm in different market structures. This paper re-examines whether privatization improves (or deteriorates) the environment in a mixed duopolistic framework with differentiated product and pollution abatement. It is shown that, due to privatization, less attention is paid to pollution abatement by all the firms coupled with less environment taxes levied by the government in a differentiated duopoly, and the environment is more (less) damaged when the product is less (more) substitutable. When the product is highly substitutable, industry profits increase because this softens the intensity of the product market, but social welfare deteriorates accompanied with the path of privatization because the loss of consumer surplus and tax revenue exceeds the increases in profits, even if the environment is less damaged.     

Abatement R&D,market imperfections,and environmental policy in an endogenous growth model

We develop an endogenous growth model featuring environmental externalities, abatement R&D, and market imperfections. We compare the economic performances under three distinct regimes that encompass public abatement, private abatement without tax recycling, and private abatement with tax recycling. It is found that the benefit arising from private abatement will be larger if the degree of the firms’ monopoly power is greater. With a reasonably high degree of monopoly power, a mixed abatement policy by which the government recycles environmental tax revenues to subsidize the private abatement R&D is a plausible way of reaching the highest growth rate and welfare.     

Delegation in a mixed oligopoly: the case of multiple private firms

Previous research examining mixed duopolies shows that the use of an optimal incentive contract for the public firm increases welfare and that privatization reduces welfare. We demonstrate that these results do not generalize to a mixed oligopoly with multiple private firms. We derive the optimal incentive contract for a public firm that weighs both profit and welfare and show that its use may either increase or decrease welfare depending on the number of private firms and the exact nature of costs. We also identify the conditions that determine whether or not privatizing the public firm facing an optimal incentive contract reduces welfare. Copyright © 2008 John Wiley & Sons, Ltd.     

THE THEORY OF STATE-OWNED ENTERPRISES IN MARKET ECONOMIES

Abstract. Four topics are covered: the circumstances under which state-owned enterprises (SOEs) are more effective than private firms; the different approaches to modelling public and private firms; the performance of SOEs; and strategies including privatization to limit their more damaging effects. It is argued that ideological or development motives are important in their genesis, but that if efficiency and innovation are key considerations the normative case for their existence is more doubtful. Various types of SOE model are identified, deriving from the variety of circumstances in which they operate, and the theoretical perspective of the modeller. These include the property rights school, the public choice tradition, neoclassical, behavioural and budget maximizing approaches. All models assume the existence of monitoring problems, created by informational asymmetry. The consequences can include high non-pecuniary benefits for managers, a concentration on monitored activities, and lower innovation levels and efficiency than private firms. Curiously this is not necessarily reflected in higher prices or costs. Possible remedial strategies include a change of ownership, a change of objectives, the introduction of incentive-compatible payment schemes, improved performance indicators and privatization.     

Optimal regulation of technical progress in natural monopolies with asymmetric information

The focus of this paper is to characterize regulatory mechanisms for natural monopolies to provide for optimal technical progress when information is asymmetric. We model a Bayesian-Nash game where the monopolist has private knowledge of the cost-reducing effects of R&D investment to generate process innovations. In the first case, a price-regulated, profit-maximizing firm whose R&D level is unobservable sets its R&D level efficiently to maximize profits at the output level chosen by the firm. However, the level of technical progress achieved by the firm in this case is too high from the regulator's point of view since, in the second-best regulated solution of interest, the regulator has to provide for the R&D expenditures, assumed sunk, as well as for information rents transferred to the firm. In a second case, it can be shown that if the regulator can observe and set limits on the firm's investment in R&D, social welfare is improved, even though the regulated investment level is no longer efficient at the output level chosen by the firm. The reason for the welfare improvement is that losses in consumer surplus due to a decrease in output and an increase in the price are offset by a decrease in information rents and R&D costs transferred, causing the social costs of public funds to fall.

Asymmetric Information, Bargaining, and International Mergers

The formation of international mergers is examined in the presence of two kinds of asymmetric information, one when a local firm has private information on market size and the other when a foreign firm has private information on its technology. In each situation, parametric configurations are identified under which a merger offer may or may not be made. It also examines the kind of offer and the probability of its acceptance. The likelihood of a merger beingformed is also related to the basic market size, demand uncertainty, and cost uncertainty. Welfare effects of tax/subsidy policies by the host country are also analyzed.     

Public intervention in UK small firm credit markets: Value-for-money or waste of scarce resources?

Loan guarantee schemes are used in many countries to provide financial support to small firms by guaranteeing loans from commercial banks, but questions remain about whether public intervention in private credit markets to support entrepreneurial firms is justified. This paper examines whether the UK Small Firms Loan Guarantee Scheme (SFLG) provides value-for-money to the UK tax payer, presenting a regression based performance approach which then feeds into a formal cost–benefit analysis. Specifically, we consider whether firm performance post-investment is such that it justifies the governments’ presence in the lending market and the costs associated with it. Our findings suggest that entrepreneurial firms that are able to access new finance through SFLG achieve superior performance in the form of improved sales, job creation and exports and that this justifies public intervention in private credit markets.     

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.     

A theory of interregional tax competition

A general equilibrium model is constructed to study tax competition, where local governments compete for capital by holding down property tax rates and public expenditure levels. An exact definition of tax competition is provided, and both the existence and nonexistence of tax competition are shown to be theoretically possible. It is argued, however, that tax competition must occur under empirically reasonable conditions. Inefficiency in public production is also explicitly modeled. The amount of capital used to produce a given level of public service output is shown to be greater than that which is required to minimize costs evaluated at the prices facing private firms.     

Tax avoidance in different firm types and the role of nonfamily involvement in private family firms

This study simultaneously distinguishes between private family firms, private nonfamily firms, public family firms, and public nonfamily firms. We show that private family firms avoid taxes less than public family firms and public nonfamily firms; however, we do not find a difference between private family firms and private nonfamily firms. Therefore, building on family firm heterogeneity, our results indicate that tax avoidance in private family firms differs depending on the involvement of nonfamily owners and/or managers. We find that private family firms that are wholly owned and managed by family members indeed avoid taxes less than private nonfamily firms.     

Capital-tax financing and scale economies in public-input production

Contrary to the dominant view of inefficient tax competition, Oates and Schwab (1991) show that capital-tax financing of public inputs leads to efficiency when the supply of these inputs is conditioned on business investment (Oates, W.E., Schwab, R.M., 1991. The allocative and distributive implications of local fiscal competition). This paper demonstrates that the cost structure of public-input production is relevant to their proposition on efficient capital-tax financing. That proposition holds if the per-unit cost of public inputs is exogenously fixed; however, it does not hold if public-input production exhibits scale economies. Also, this paper compares our analysis with the Zodrow-Mieszkowski model. That comparison illustrates the importance of the way public inputs are rationed to private firms.
