Environmental Compliance by Firms in the Manufacturing Sector in Mexico

To date, little empirical evidence exists to help regulators understand why some firms comply even when there is little financial incentive to do so and others continually violate environmental regulations. This paper examines data on compliance with environmental regulations within the manufacturing sector in Mexico. The probability of complying depends, among other factors, on the kind of management practices of the firm and the level of environmental training. Some firms in the manufacturing sector over-comply with regulations. Our results show that providing environmental training to employees in the firm increases the probability of over-compliance. Local community has a positive impact on over-compliance however the magnitude of its impact is not as strong as is often suggested in the literature.Environmental regulation, Compliance, Mexico

Impact of Risk and Uncertainty in the Provision of Local and Global Environmental Goods : An Experimental Analysis

Uncertainties and risks in the decision making process are abundant in the area of environmental economics, irrespective of whether the problems being discussed are local or global. This paper uses laboratory evidence from public goods games to examine how in payoff equivalent situations, decision makers contribute towards local or global environmental goods, in the presence of risk and uncertainties in the provision of these goods. We use a within subject design that allows for comparisons across seven different treatments in which subjects are exposed to internal (strategic) and external (environmental) risk and uncertainty. Our results show that the location of the risk and uncertainty matters, with subjects moving away from the external uncertainty in favor of internal uncertainty, when that uncertainty is associated with the local environmental good. When the uncertainty relates to the global environmental good, subjects face both external and internal uncertainty on the same good leading to a significant drop in contributions. We find that in the presence of risk and uncertainty subjects use feedback from other members of their group when deciding about future contributions. The reward for research and development and innovation is captured in the experimental design by the increased probability of obtaining the desired outcome in the endogenous probability treatment. Subjects seem to understand this incentive and contribute more towards global goods in this treatment.Experiments, Public Goods, Local and Global Environmental Problems, Risk, Uncertainty.

Does the Size of the Action Set Matter for Coorperation

We use the voluntary contribution mechanism to investigate whether smaller action sets lead to higher cooperation rates. We ?nd that this is the case for groups of four players.action set; voluntary contribution mechanism; prisoner?s dilemma

Designing Self-Reporting Regimes to Encourage Truth Telling: An Experimental Study

We report results from an experiment that investigates truthfulness in self-reporting under different reporting regimes. The experiment involves a production task with self-reporting of accidents, with reporting compulsory for some participants, but only voluntary for others. We find that dishonesty is prevalent, but accident reporting is more frequent with compulsory reporting compared with voluntary. This suggests that lie aversion is a stronger force than the intrinsic motivation to voluntarily report, and that careful design of self-reporting regimes is necessary by enforcement agencies to achieve satisfactory compliance outcomes. Our results are relevant for several areas beyond regulatory compliance, including dishonesty in social security claims, insurance claims, workplace expense claims, income tax returns, and financial reporting.

Emissions Variability in Tradable Permit Markets with Imperfect Enforcement and Banking

Unexpected variation in emissions can have a substantial impact on the prices and efficiency of tradable emission permit markets. In this paper we report results from a laboratory experiment in which subjects participate in an emissions trading market in the presence of emissions uncertainty. Subjects face exogenous, random positive or negative shocks to their emission levels after they make production and emission control plans. In some sessions we allow subjects to bank their unused permits for future use. In all sessions, subjects can trade in a reconciliation period to buy or sell extra permits following the shock realization. Subjects then report their emissions to the regulatory authority and they are placed in different inspection groups depending on their compliance history. The design of our experiment allows us to identify important interactions between emission shocks, banking, compliance and enforcement. We find that the relationship between emission shocks and price changes is significantly stronger without banking, so banking helps smooth out the price variability arising from the imperfect control of emissions. This greater price stability comes at a cost, however, since noncompliance and emissions are significantly greater when banking is allowed.Emissions Trading, Correlated Shocks, Banking, Laboratory Experiments.

An Experimental Study of Compliance and Leverage in Auditing and Regulatory Enforcement

Evidence suggests that a large majority of firms and individuals comply with regulations and tax laws even though the frequency of inspections and audits is often low. Moreover, fines for noncompliance are also typically low when regulatory violations are discovered. These observations are not consistent with static compliance models. Harrington (1988) modified these static models by specifying a dynamic game in which some agents have an incentive to comply even when the cost of compliance each period is greater than the expected penalty. This paper reports a laboratory experiment based on the Harrington model framework, in which subjects move between two inspection groups that differ in the probability of inspection and severity of fine. Subjects decide to comply or not in the presence of low, medium or high compliance costs. Enforcement leverage arises in the Harrington model from movement between the inspection groups based on previous observed compliance and noncompliance. Our results indicate that consistent with the model, violation rates increase when compliance costs become higher and as the probability of switching groups becomes lower. Behavior does not change as sharply as the model predicts, however, since violation rates do not jump from 0 to 1 as parameters vary across critical thresholds. A simple model of bounded rationality explains these deviations from optimal behavior.Regulatory Compliance, Laboratory Experiments, Tax.

A LABORATORY COMPARISON OF UNIFORM AND DISCRIMINATIVE PRICE AUCTIONS FORREDUCING NON-POINT SOURCE POLLUTION

Land use changes to reduce non-point source pollution, such as nutrient runoff to waterways from agricultural production, incur opportunity costs that are privately known to landholders. Auctions may permit the regulator to identify those management changes that have greater environmental benefit and lower opportunity cost. This paper reports a testbed laboratory experiment in which landowner/sellers compete in sealed-offer auctions to obtain part of a fixed budget allocated by the regulator to subsidize pollution abatement. One treatment employs uniform price auction rules in which the price is set at the lowest price per unit of environmental benefits submitted by a seller who had all of her offers rejected. Another treatment employs discriminative price rules in which successful sellers receive their offer price. Our results indicate that subjects recognize the cost-revelation incentives of the uniform price auction, as a majority of offers are within 2 percent of cost. By contrast, a majority of offers in the discriminative price auction are at least 8 percent greater than cost. Nevertheless, the regulator spends more per unit of environmental benefit in the uniform price auction, and the discriminative price auction has superior overall market performance.Uniform Price Auctions, Discriminative Price Auctions, Land Use Change,Laboratory Experiments, Environmental Policy.

An Experimental Analysis of Group Size and Risk Sharing

We study the relationship between group size and the extent of risk sharing in an insurance game played over a number of periods with random idiosyncratic and aggregate shocks to income in each period. Risk sharing is attained via agents that receive a high endowment in one period making unilateral transfers to agents that receive a low endowment in that period. The complete risk sharing allocation is for all agents to place their endowments in a common pool, which is then shared equally among members of the group in every period. Theoretically, the larger the group size, the smaller the per capita dispersion in consumption and greater is the potential value of insurance. Field evidence however suggests that smaller groups do better than larger groups as far as risk sharing is concerned. Results from our experiments show that the extent of mutual insurance is significantly higher in smaller groups, though contributions to the pool are never close to what complete risk sharing requires.Reciprocity, Risk Sharing, Group Size, Experiments.

Behavioural Anomalies, Bounded Rationality and Simple Heuristics

The use of bounded rationality in explaining economic phenomena has attracted growing attention. In spite of this, there is still considerable disagreement regarding the meaning of bounded rationality. Basov (2005) argues that when modeling boundedly rational behaviour it is desirable to start with an explicit formulation of the learning process. A complete understanding of the boundedly rational decision-making process requires development of an evolutionary-dynamic model which can give rise to such learning processes. Evolutionary dynamics implies that individuals use heuristics to adjust their choices in light of past experiences, moving in the direction that appears most beneficial, where these adjustment rules are assumed ‘hardwired’ into human cognition through the process of biological evolution. In this paper we elaborate on the latter point by building a model of evolutionary selection relevant to heuristics. We show that in addition to explaining the origin of learning rules this approach also sheds light on some well documented preference anomalies.Bounded Rationality;Heuristics;Replicator Dynamics

Can Real-Effort Investments Inhibit the Convergence of Experimental Markets?

Evidence shows that real-effort investments can affect bilateral bargaining outcomes. This paper investigates whether similar investments can inhibit equilibrium convergence of experimental markets. In one treatment, sellers’ relative effort affects the allocation of production costs, but a random productivity shock ensures that the allocation is not necessarily equitable. In another treatment, sellers’ effort increases the buyers’ valuation of a good. We find that effort investments have a short-lived impact on trading behavior when sellers’ effort benefits buyers, but no effect when effort determines cost allocation. Efficiency rates are high and do not differ across treatments.Property Rights; Real Effort; Posted Offer Markets; Random Shock; Surplus Creation
