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.     

Quality distortions in vertical relations

This paper examines how delivery tariffs and private quality standards are determined in vertical relations that are subject to asymmetric information. We consider an infinitely repeated game where an upstream firm sells a product to a downstream firm. In each period, the firms negotiate a delivery contract comprising the quality of the good as well as a non-linear tariff. Assuming asymmetric information about the actual quality of the product and focusing on incentive compatible contracts, we show that from the firms’ perspective delivery contracts lead to more efficient contracts and thus higher overall profits the lower the firms’ outside options, i.e. the higher their mutual dependency. Buyer power driven by a reduced outside option of the upstream firm enhances the efficiency of vertical relations, while buyer power due to an improved outside option of the downstream firm implies less efficient outcomes.     

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.     

Technology adoption decisions under a mixed regulatory system of tradable permits and air pollution fees for the control of Total Suspended Particulates in Taiwan

By using a newly proposed tradable permit system built under the current air pollution fee regulation for the control of Total Suspended Particulates in Taiwan as an example, a mixed-integer non-linear programming model that minimizes the total regulatory costs of firms is applied to investigate how different permit trading ratios and the design of banking might affect firms’ technology adoption decisions and permit trading behavior. By incorporating binary variables in the model to represent firms’ decisions as to whether or not to install new control equipment, the results show that when the unit air pollution fee rate is higher than the firms’ abatement costs, the design of banking causes many firms to install new control equipment that results in an over-reduction of emissions. If no air pollution fee is imposed, the trading ratio plays a more important role than the reservation rate for banking in determining the firms’ emission reduction strategies under a pure permit trading scheme. While the conclusion from this study that uses a non-uniformly mixed pollutant as an example may hold only when certain conditions are met, the framework can be applied to other uniformly mixed pollutants through parameter changes without any limitation. In addition, the modeling technique presented here offers policy-makers a very convenient approach to empirical analysis.      

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.      

Collusive behavior under a leniency program

We investigate how a leniency program, which is a policy that gives reduced penalties to colluding firms that cooperate with investigations of the Antitrust Authority, affects firms’ collusive behavior. Using a model of quantity competition, we show that an amnesty to the second or later candidates of a leniency program is of no use if colluding firms can choose the most profitable collusion. Because a leniency program is a general rule that is applied to various markets in a country, our result implies that the design of a leniency program depends on which kinds of market structure are prevalent in the country.     

Does macro-economy have any effect on firm investment-cash flow sensitivities?

We conduct an empirical study on Chinese listed firms’ investment-cash flow sensitivities in different stages of the macroeconomic cycle during 1993–2004, and find that macro-economy has a significant effect on investment-cash flow sensitivities. When economic slowdown occurred between 1998 and 2001, sample firms reduced working capital substantially to maintain some necessary investment level of fixed assets, that is, firms stabilized fixed assets investment by adjusting working capital. However, the sensitivity coefficients of fixed assets investment to cash or sales revenue were not systematically higher in the depressed stage than in the booming stage.      

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.      

Does services liberalization affect manufacturing firms’ export performance? Evidence from India

This paper investigates the relationship between the reform of energy, telecommunications and transport services in India in the mid-1990s and manufacturing firms’ export performance. The empirical analysis relies on exogenous indicators of regulation of Indian services sectors and detailed firm-level data from India in the 1994–2004 period. I find that the reform of upstream services sector has increased the probability of exporting and export sales shares of firms producing in downstream manufacturing industries. The results suggest that the effect of services liberalization on manufacturing firms’ export performance is stronger for initially more productive firms. These empirical findings are robust to alternative econometric specifications that control for other reforms, industry, firm characteristics and that deal with potential reverse causality concerns.     

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.     

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.     

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.     

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.     

Pricing inputs to induce efficient Make-or-Buy decisions

We investigate input pricing regimes that induce efficient Make-or-Buy decisions by entrants when there is constant returns in the production of the input(s) and simultaneous noncooperative price competition in downstream retail markets. Necessary and sufficient conditions for efficient Make-or-Buy decisions are derived. The necessary condition shows that input prices are relevant for Make-or-Buy decisions except under restrictive and often unverifiable assumptions on the demand structure, and that the least informationally-demanding way to ensure efficient Make-or-Buy decisions is to price inputs at marginal cost provided changes in the entrant’s cost have a “normal” effect on the entrant’s profit. The conditions also show that pricing the incumbent’s input at the entrant’s marginal cost always ensures efficient Make- or-Buy decisions. The extent to which input prices can depart from marginal cost while still inducing efficient Make-or-Buy decisions increases with the efficiency differential between the incumbent and entrant and with the demand displacement ratio.      

The welfare effects of entry: the role of the input market

In a successive Cournot oligopoly, we show the welfare effects of entry in the final goods market with no scale economies but with cost difference between the firms. If the input market is very concentrated, entry in the final goods market increases welfare. If the input market is not very concentrated, entry in the final goods market may reduce welfare if the entrant is moderately cost inefficient. Hence, entry in the final goods market is more desirable if (1) the input market is very concentrated or (2) the cost difference between the incumbents and the entrant is either very small or very large. It follows from our analysis that entry increases the profits of the incumbent final goods producers if their marginal costs are sufficiently lower than the entrant’s marginal cost.     

Effects of vertical integration on price and volume: An empirical inquiry

A simple model with two stages of production is used for deriving some empirically testable hypotheses. Firms (two upstream and two downstream) in the industry are either vertically integrated or not, hence the industry has three alternative patterns: Complete unintegrated, partially integrated, or fully integrated.Final good prices, outputs and profits of firms are different in each integration pattern but what is optimal can not be stated (i.e., pay-offs are much too complicated in order to solve the sub-game equilibrium).The essential feature of the model is that there are external markets for the intermediate inputs. Hence input trade between the four firms/divisions need not balance since excess supply or demand is traded at the external market. With this feature purely downstream exogenous shocks have no effect on upstream pricing nor production decisions if all four firms are unintegrated. Such exogenous shocks have non-zero effects if at least one firm is vertically integrated. There are also other dissimilarities in comparative statics of each industry integration pattern.An indirect method to test the effects of vertical integration on price and volume is presented and empirically tested. Depending on the vertical integration pattern of an industry exogenous shocks have dissimilar effects on prices and outputs of the final and intermediate good. A four equations system is estimated by using Finnish forest industry firm data. Final good demand rise has a reducing effect on both paper and pulp prices. Stumpage prices (upstream marginal costs) have a negative impact on paper and pulp production and a positive impact on prices. These effects from upstream (downstream) stage into downstream (upstream) market should not occur when all firms are unintegrated.This is a revised version of a paper which was presented at seminars at Brussels, Turku, Vienna, and Stuttgart.

Minimum quality standards and consumers’ information

The literature so far has analyzed the effects of minimum quality standards (MQS) in oligopoly, using models of pure vertical differentiation, with only two firms, and perfect information. We consider products that are differentiated horizontally and vertically, with imperfect consumers’ information, and more than two firms. We show that a MQS changes the consumers’ perception of produced qualities. This increases the firms’ returns from quality enhancing investments, notwithstanding contrary strategic effects. Our analysis justifies the use of MQS in industries where consumers cannot precisely ascertain the quality of goods, for instance pharmaceuticals or products with chemical components involved.

Product liability and the virtues of asymmetric information

This paper analyzes a two-period setup in which firms differ with respect to costs of care and may use care-taking to signal type to consumers, who are able to observe precaution taken only ex post. Applying the refinement of the intuitive criterion to the concept of the perfect Bayesian equilibrium, we establish a unique separating equilibrium for every share of harm borne by firms. For low levels of victim compensation, we show that (i) firms choose weakly higher care in a setting in which customers do not know the firms’ type than in a setting in which they do, and (ii) the deviation in precaution taken due to asymmetric information on firm type is welfare-improving.
