A Note on Emissions Taxes and Incomplete Information

In contrast with what we perceive is the conventional wisdom about setting a second-best emissions tax to control a uniformly mixed pollutant under uncertainty, we demonstrate that setting a uniform tax equal to expected marginal damage is not generally efficient under incomplete information about firms’ abatement costs and damages from pollution. We show that efficient taxes will deviate from expected marginal damage if marginal damage is increasing and there is uncertainty about the slopes of the marginal abatement costs of regulated firms. Moreover, tax rates will vary across firms if a regulator can use observable firm-level characteristics to gain some information about how the firms’ marginal abatement costs vary.     

On a Fundamental Advantage of Permits Over Taxes for the Control of Pollution

We extend the tax versus permits literature by considering permit supply functions and pollution tax functions that are generalizations of the usual constant permit supply and constant pollution tax rate. In our model, pollution is not uniformly mixed and the regulator is uncertain about the polluting firms’ abatement costs. We determine the optimal permit supply functions and the optimal pollution tax functions. Using these functions, we show that permits lead unambiguously to lower total expected costs than taxes. We analyze the magnitude of this difference for a simple model of climate change. By relating the optimal permit supply functions to Weitzman (Am Econ Rev 68:683–691, 1978) we provide a new interpretation of his results.     

Capital endowment, credit constraint and FDI: Analysis based on heterogeneous firms

To examine the impact of capital endowment and credit constraint on firms’ FDI decisions, we build a model of investment portfolio based on heterogeneous firms setup. We find that financial factors matter for firms’ internationalization. More capital endowment or less credit constraint lowers cutoff productivity for firms to do FDI.     

An Integrated Model of the Adoption and Extent of E-Commerce in Firms

This work aims to explain firms’ decisions to adopt Internet-based e-commerce, and the extent to which the adopters subsequently implement e-commerce to commercialize their products and services. We examine various types of factors previously considered by the literature (competitive environment, organizational characteristics, strategic orientation, innovative capacity, managers’ characteristics, IT equipment possessed and the use made of it). The analytical model developed here on the basis of a sample of 2,038 firms suggests that the factors influencing the adoption decision are different from those that eventually influence the results of firms’ commercial operations on the Internet. Likewise, we discuss the contribution of each type of determinant and the implications.      

Abuse of EU Emissions Trading for Tacit Collusion

In this paper, we show that loopholes in EU emissions trading law foster tacit collusion that impacts oligopolistic product markets. The abuses originate from the covert misuse of EU emissions trading institutions, such as pooling or project-based mechanisms. We analyse two types of these loopholes by means of game theoretical methods to show how oligopolistic firms establish output restrictions, even if those firms are price takers on the~permit market (which might actually be the case for the majority of obligated firms in the EU). The identified misuse of emissions trading law increases firms’ profits, decreases the consumers’ surplus and has negative effects on social welfare for specified parameter ranges. Consequently, public authorities should not allow emissions trading’s overall good reputation—based upon its efficient abatement of pollution—to blind them to options in European emissions trading legislation that would eventually restrict competition.      

Which Firms are More Sensitive to Public Disclosure Schemes for Pollution Control? Evidence from Indonesia’s PROPER Program

This paper analyzes differences in firms’ responsiveness to PROPER, Indonesia’s public disclosure program for industrial pollution control. The overall effectiveness of this program at achieving emissions reductions and its low regulatory costs have earned it a good reputation around the world. PROPER had no deterrents or incentives other than those that arose indirectly from publicly disclosing information about the environmental performances of firms. We analyzed plant-level data to relate short- and longer-term environmental responses to facility characteristics. The results revealed that foreign-owned firms were consistently more likely to respond to the environmental rating scheme, compared to private domestic firms. This is a clear and important insight with consequences for a number of issues, such as understanding the pollution haven debate. Also, firms located in densely populated regions, particularly in Java, responded more positively to the public disclosure of PROPER ratings. The main observed effect was however given by the initial level of environmental performance of firms. Those firms that had bad environmental performance records felt pressure to improve, but if the initial abatement steps had already been taken, the incentives to improve further appeared to diminish.     

Backward integration and collusion in a duopoly model with asymmetric costs

This paper formalizes the idea that input transactions might be used to implement side payments among colluding firms. A model is proposed to analyze the effect of backward integration on collusive outcomes in a downstream duopoly with asymmetric marginal costs. Vertical integration expands the set of collusive outcomes that are sustainable for a given realization of the discount factor. This is an additional effect of vertical integration that antitrust authorities should consider. Side payments implemented by input sales are more relevant the larger the difference in marginal costs, since they allow for the shifting of production towards the relatively more efficient firms, while maintaining firms’ incentives to collude. A price of the input above that posted by an alternative source or sales of the input below cost may be observed, depending on the realization of downstream firms’ costs.      

Taxes versus quantities for a stock pollutant with endogenous abatement costs and asymmetric information

We compare emissions taxes and quotas when a (strategic) regulator and (non-strategic) firms have asymmetric information about abatement costs, and all agents use Markov perfect decision rules. Firms make investment decisions that affect their future abatement costs. For general functional forms, firms’ investment policy is information-constrained efficient when the regulator uses a quota, but not when the regulator uses an emissions tax. This advantage of quotas over emissions taxes has not previously been recognized. For a special functional form (linear–quadratic) both policies are constrained efficient. Using numerical methods, we find that a tax has some advantages in this case.     

Creation of jobs and firm-sponsored training in a matching model of unemployment

We offer a search and matching model with firms that create job vacancies and are willing to sponsor general skills training. The spillover of skilled labor between firms has the dual effect of increasing job vacancies and enhancing firms’ incentives for free riding. The former effect is combined with a reduction in search costs to cause a positive feedback between the supply of skilled labor and the creation of job vacancies, suggesting that firms encourage each other. On the other hand, with the latter effect, search costs are reduced, inducing firms to take a free ride on each other’s investments, thereby decreasing the supply of skilled labor and the creation of job vacancies. A reduction in search costs can lead to different results depending on which of the two mechanisms is actualized. Additionally, our analysis allows for “labor poachers,” or firms absorbing skilled labor in the market, to consider direct competition between training firms and poaching firms.      

Adoption of Pollution Prevention Techniques: The Role of Management Systems and Regulatory Pressures

This paper investigates the extent to which firm level technological change that reduces unregulated emissions is driven by regulatory pressures, and firms’ technological and organizational capabilities. Using a treatment effects model with panel data for a sample of S&P 500 firms over the period 1994–1996, we find that organizational change in the form of Total Quality Environmental Management leads firms to adopt pollution prevention practices, after controlling for the effects of various regulatory pressures and firm-specific characteristics. We find that the threat of anticipated regulations and the presence of ‘complementary assets’ is important for creating the incentives and an internal capacity to undertake incremental adoption of pollution prevention techniques.     

Nonpoint Source Pollution Taxes and Excessive Tax Burden

If a regulator is unable to measure firms’ individual emissions, an ambient tax can be used to achieve the socially desired level of pollution. With this tax, each firm pays a unit tax on aggregate emissions. In order for the tax to be effective, firms must recognize that their decisions affect aggregate emissions. When firms behave strategically with respect to the tax-setting regulator, under plausible circumstances their tax burden is lower under an ambient tax, relative to the tax which charges firms on the basis of individual emissions. Firms may prefer the case where the regulator is unable to observe individual firm emissions, even if this asymmetric information causes the regulator to tax each firm on the basis of aggregate emissions.     

Eco-Labeling and Market Equilibria with Noisy Certification Tests

An intriguing alternative to traditional methods for regulating externalities is the provision of information about firms’ environmental attributes. An increasingly important example of this approach is “eco-labeling,” where a third party certifies firms’ products. Such schemes are currently used in a variety of countries. This paper investigates the equilibria that may occur with eco-labeling, and the attendant welfare effects. I model certification as a noisy test, subject to both type I and type II errors, but where green firms more likely to pass than brown firms. While it commonly leads to an increase in the fraction of green units in the market, the introduction of an eco-label can either increase or decrease welfare.     

Effluent taxes,market structure,and the rate and direction of endogenous technological change

This paper studies the effects of effluent taxes on firms’ allocation of resources to cost-reducing and emission-reducing R&D, and on entrepreneurs’ decisions to develop new goods and enter the market. A tax set at an exogenous rate that does not depend on the state of technology reduces growth, the level of consumption of each good, and raises the number of firms. The induced increase in the variety of goods is a benefit not considered in previous analyses. In terms of environmental benefits, the tax induces a positive rate of pollution abatement that offsets the “dirty” side of economic growth. A tax set at an endogenous rate that holds constant the tax burden per unit of output, in contrast, has ambiguous effects on growth, the scale of activity of each firm and the number of firms. Besides being novel, the potential positive growth effect of this type of effluent tax is precisely what makes this instrument effective for welfare-maximizing purposes. The socially optimal policy, in fact, requires the tax burden per unit of output to equal the marginal rate of substitution between the growth rate of consumption and abatement. Moreover, a tax/subsidy on entry is needed, depending on whether the contribution of product variety to pollution dominates consumers’ love of variety.      

The World of Regulatory Influence

Models of firms’ influence over the regulatory agencies that oversee them have traditionally been constrained by several factors, including a lack of direct measures of “influence,” an inability to account for variations in the institutional environment within which firms operate, and a nearly singular focus on industry-level measures of interest group strengths. In this paper, we employ a global database and novel measures to provide a fresh look at the determinants of firms’ influence over regulatory agencies. We find that in addition to traditional industry-level determinants, important country-level institutional and firm-level determinants affect firms’ regulatory agency influence. We also find that regulatory process variations affect firms’ influence over regulators. With these empirical estimates in hand, we generate a Regulatory Influence Index that ranks influence levels of typical firms that operate in each sample country in the dataset, and then discuss the substantial country-level variation in regulatory agency influence that obtains.     

Intertemporal Emission Permits Trading Under Uncertainty and Irreversibility

This paper analyzes the effect of emission permit banking on clean technology investment and abatement under conditions where the stringency of the future cap is uncertain. We examine the problem of heterogeneous firms minimizing the cost of intertemporal emission control in the presence of stochastic future pollution standards and emission permits that are tradable across firms and through time. A firm can invest in clean capital (an improved pollution abatement technology) to reduce its abatement cost. We consider two possibilities: that investment is reversible or irreversible. Uncertainty is captured within a two period model: only the current period cap is known. We show that if banking is positive and marginal abatement costs are sufficiently convex, there will be more abatement and investment in clean technology under uncertainty than there would be under certainty and no banking. These results are at odds with the common belief that uncertainty on future environmental policy is a barrier to investment in clean capital. Moreover, under uncertainty and irreversibility, we find that there are cases where banking enables firms to invest more in clean capital.     

Creative Disasters? Flooding Effects on Capital,Labour and Productivity Within European Firms

This paper examines the impact of floods on the firms’ capital accumulation, employment growth and productivity by using a difference-in-difference (DID) approach and considering the firms’ asset structure. We find evidence that, in the short run, companies in regions hit by a flood show on average higher growth of total assets and employment than firms in regions unaffected by flooding. The positive effect prevails for companies with larger shares of intangible assets. Regarding the firms’ productivity a negative flood effect is observable which declines with an increasing share of intangible assets.      

Demand fluctuations and capacity utilization under duopoly

Summary.  This paper studies the impact of uncertain demand on firms’ capacity decisions when they operate in an oligopolistic environment. We define a two-stage game where firms choose capacity in the first stage without knowing which state of Nature is going to realize, and output levels in the second, knowing which state is realized. We prove the existence of a symmetric subgame perfect equilibrium at which firms are in excess capacity compared with the capacity they would choose in the Cournot certainty equivalent game.

Corporate Expenditure on Environmental Protection

We examine the determinants of firm’s current environmental expenditure and firm’s capital investment in equipment for pollution control in Irish manufacturing industries using a Heckman selection model. The main determinants for the two types of expenditure are similar: larger, exporting and energy-intensive firms are more likely to spend. Being subject to environmental regulation also has an effect. Once the decision to commit resources has been taken, larger, older, foreign-owned, exporting and energy-intensive firms incur higher environmental expenditure. For the amount of capital investment only firm size and age play a role. This suggests that the economic and regulatory incentives in place are such that it is the largest and most polluting firms that do most to reduce pollution.     

Ownership, institutions, and capital structure: Evidence from China

We employ a unique data set to explore the role of ownership structure and institutional development in debt financing of non-publicly traded Chinese firms. We show that state ownership is positively associated with leverage and firms’ access to long-term debt, while foreign ownership is negatively associated with all measures of leverage. Surprisingly, firms in better developed regions are associated with reduced access to long-term debt, suggesting the availability of alternative financing channels and the tightening of the lending standards under the on-going banking reform. The combination of ownership structures and institutions explains up to 6% of the total variation in firms’ leverage decisions, while firm characteristics alone explain no more than 8% of the variation. Further, we show that non-state-owned firms tend to have lower total and short-term debt than their state-owned counterparts in less developed regions. Finally, we show that state-owned firms’ easy access to long-term debt is positively associated with long-term investment and negatively associated with firm performance.     

Demand competition and investment heterogeneity in industries based on systemic technologies: evidence from the US long-distance telecommunications services industry, 1984–1996

Industries based on systemic technologies are often characterized by a dynamically evolving market structure. The market structure that provides the context for firms’ investment choices itself evolves due to the feedback effect of firms’ investments. In such cases, analyses of investment-performance relationship, purporting to explain sustainable competitive advantages, should ideally account for the endogeneity of the determinants of market structure—technology, demand, and policy—and firms’ investment choices. This paper focuses on the endogeneity of the demand-side determinants of market structure and firms’ demand-side investments under the assumed conditions of constant technology and policy environment. In doing so it contradicts the extant depiction of the evolution of industrial market structure in the above context as primarily caused by the evolution of underlying technological system in response to firms’ endogenous technological investments that generate sustainable competitive advantage for the dominant firms. A dynamic evolutionary model of demand competition captures the competition in the downstream market for basic industry product and its complements in an industry based on systemic technology during its post-interoperability stage. A natural experiment drawn from the US Long-distance telecommunications services industry during 1984–1996 allows testing the hypotheses drawn from the above model in a panel data setting.
