environmental regulation technological diversity and the dynamics of technological change inducing technological progress is an important objective of environmental regulation we investigate under which conditions regulation induced technological progress pursues the best technological option we analyze a setting with vertical and horizontal technological progress cost uncertainty time limited patent protection and a case that is typical for some emissi4on intensive industries like electricity generation or the chemical industry under taxes and standards only the current least cost technology is used and developed implying a lock in into a possibly inferior technology tradable permits yield slower progress but can facilitate the simultaneous development of technologies rendering lock ins less likely

on the option to invest in pollution control under a regime of tradable emissions allowances optimal decisions of a firm facing the option of retrofitting its plant to reduce pollution and thereby eliminate the need to purchase emissions allowances are analysed the decision is treated as a real option with the price of pollution permits following a known stochastic process the model is formulated as a set of one dimensional partial differential equations at discrete points in time the firm owner makes optimal decisions about the retrofit including whether to mothball temporarily the model is used to analyse a firm s decision to instal a scrubber as a result of the 1990 u s clean air act jel classification q25 d81 g31 sur la possibilite d investir dans le controle de la pollution dans un regime de permis d emission de pollution echangeables commercialement ce memoire examine les decisions optimales d une entreprise face a la possibilite d adapter ses installations pour reduire la pollution et ce faisant d eliminer le besoin de se procurer des permis d emission de pollution sur le marche le decision est traitee comme une option reelle ou le prix des permis resulte d un processus stochastique connu le modele est formule sous forme d un ensemble d equations differentielles partielles a une dimension a des points discontinus dans le temps le proprietaire de l entreprise prend des decisions optimales de mise a niveau des installations y compris la possibilite de les fermer temporairement le modele est utilise pour analyser une decision d installer un epurateur suite a la mise en place de la loi americaine de 1990 clean air act

shipwrecks and treasure hunters we examine dynamic search as a game in which two rivals explore an island for a hidden prize of known value in every period until its discovery the players decide how much of the unsearched area to comb if a player finds the prize alone he wins it and the game ends players have a per period discount factor and costs proportional to the area they search first as a benchmark for efficiency we solve the one player search problem second in the two player setting we show that typically there is inefficient over search a result akin to the tragedy of the commons however for players with intermediate levels of patience there is the possibility of inefficient under search as players incorporate the expected future payoffs in their current search decisions finally with patient players several counterintuitive results can arise for example players might be better off searching a larger island or looking for a less valuable prize

environmental policy adjustment costs and behavior of the firm abstract the effects of environmental policy in the form of emission charges or emission limits on the firm s optimal choices of productive and abatement inputs are analyzed short run and long run impacts on inputs and the properties of static emission function are determined through comparative static analysis comparative dynamics reveal the properties of the cumulative emission function and the cumulative shadow cost of emission limits function

a multi winner nested rent seeking contest this paper considers a symmetric imperfectly discriminating rent seeking contest in which there may be several winners we first demonstrate a serious flaw in previous work and then go on to suggest an alternative method for analyzing the contest in contrast to the previous work we show that the value of the rent is fully dissipated in equilibrium as the number of players becomes large

firm incentives to promote technological change in pollution control reply abstract the process of technological change in pollution control is broken into three basic steps innovation diffusion and optimal agency response firm incentives to promote these steps are then examined under five regulatory regimes direct controls emission subsidies emission taxes free marketable permits and auctioned marketable permits on a relative basis emission taxes and auctioned permits provide the highest firm incentives to promote technological change at times free permits generate lower incentives direct controls which are common regulatory tools usually provide the lowest relative firm incentives to promote technological change

the economics of crime and punishment an analysis of optimal penalty this paper demonstrates the optimality of a non maximal penalty in a hierarchical enforcement structure the penalty is chosen by the social planner to maximize the probability of monitoring and to minimize the probability of transgression we compare the optimal penalty levels with and without ex post flexibility wherein the players are allowed to alter their decision after they observe the social planner s choice 2000 elsevier science s a all rights reserved

the social cost of uniform regulatory standards in a hierarchical government abstract regulatory agencies charged with public health and safety typically promulgate uniform regulatory standards which suggests the agencies are concerned mainly to reduce harmful externalities with little concern for firms costs a focus on benefits to the exclusion of costs in standard setting and enforcement leads to inefficiencies we show that even when the legislature cannot peg the budget to a specific enforcement policy it can reduce the distortions by limiting the enforcement agency s budget and by permitting the agency to partially self finance from rebates of noncompliance fines

modifying variability and correlations in winner take all contests we consider contests with a fixed proportion of winners based on relative performance special attention is paid to winner take all contests which we define as contests with relatively few winners receiving relatively large awards but we consider the full range of values of the proportion of winners if a contestant has the opportunity to modify the distribution of her performance what strategy is advantageous when the proportion of winners is less than one half a riskier performance distribution is preferred when this proportion is greater than one half it is better to choose a less risky distribution using a multinormal model we consider modifications in the variability of the distribution and in correlations with the performance of other contestants increasing variability and decreasing correlations lead to improved chances of winning when the proportion of winners is less than one half and the opposite directions should be taken for proportions greater than one half thus it is better to take chances and to attempt to distance oneself from the other contestants i e to break away from the herd when there are few winners a more conservative herding strategy makes sense when there are many winners our analytical and numerical results indicate that the probability of winning can change substantially as variability and or correlations are modified furthermore in a game theoretic setting in which all contestants can make modifications choosing a riskier less risky performance distribution when the proportion of winners is low high is the dominant best response strategy we briefly consider some practical issues related to the recommended strategies and some possible extensions

a real options approach to abatement investments and green goodwill in this paper we adopt the green goodwill argument as to why firms voluntarily invest in abatement capital we investigate the effects on the abatement investment decision of changes in uncertainty about future green goodwill competitor abatement investments regulations etc using a real options framework our results indicate that increased uncertainty about consumers willingness to pay for green products in the future discourage voluntary abatement investments the model also suggests that voluntary abatement investments are promoted by an increased threat of regulation and competitor abatement investments furthermore the benefit cost ratio of the abatement investment project at the point where it is optimal to invest is independent of what regulatory regime stringent or lenient the firm operates in we also conclude that despite the fact that voluntary abatement investment exists there may still be room for environmental policy

search duplication in research and design spaces exploring the role of local competition a lack of sufficient diversification in research strategies has been identified as an important problem for delegated research we show that this problem can be solved by local competition such as bribery lobbying rent seeking competition at the patent office among players who apply the same search strategies or develop the same design such competition can restore full efficiency in the non cooperative equilibrium local competition interacts with the choice of whether to cluster or diversify and rather than adding a further inefficiency to the existing ones it eliminates inefficiency the results are robust and hold under simultaneous search strategy choices as well as for sequential choices

regulatory dealing revisiting the harrington paradox abstract despite the fact that i when the epa observes regulatory violations it rarely pursues the violator and ii the expected penalty faced by a violator who is pursued is small compared to the cost of compliance it is still the case that iii firms comply a significant portion of the time winston harrington harrington w 1988 enforcement leverage when penalties are restricted journal of public economics 37 29 53 provides a dynamic model consistent with this apparent paradox we offer an alternative rationalisation in a model of regulatory dealing in which the agency uses tolerance in some contexts to induce increased compliance in others the observed tolerance of the epa to non compliance may be a strategic response by the agency to a difficult enforcement environment rather than evidence that it has gone soft on pollution or been captured by industry interests we use the model to consider the impact of the growing trend towards citizen suits and ngo enforcement of regulation arriving at some unconventional conclusions we argue that the model is consistent with existing empirical analyses

pollution permits and environmental innovation abstract this paper starts with a warning about the negative impact of plain pollution allowance markets on environmental pollution innovation stand alone spot markets enable the government to expropriate an innovation by offering a competing technology pollution permits that puts an arbitrary downward pressure on the licensing price advance allowances reduce expropriation but still create suboptimal incentives for innovation they have the further drawback that permits are inefficiently used when the innovation occurs options to pollute at a given striking price fare better than allowances because they create private incentives to phase out pollution in the case of innovation we characterize the social optimum and show that it can be implemented by issuing options to pollute inter alia finally the paper compares ex ante and ex post government procurement surprisingly ex post licensing by the innovator to the government may yield a higher licensing fee than an ex ante contract

enforcement leverage when penalties are restricted a reconsideration under asymmetric information abstract harrington harrington w 1988 enforcement leverage when penalties are restricted journal of public economics 37 29 53 offers an explanation for how relatively high compliance rates might co exist with low expected fines his results are highly dependent on the assumptions that all firms are identical and their compliance costs are known this paper shows that harrington s results are not necessarily robust in a more general model where asymmetric information and uncertainty are present

how effective are capital controls a number of authors have recently argued that in order to avoid financial instability emerging countries should rely on capital controls two type of controls have been considered controls on capital outflows and controls on capital inflows in this paper i review the historical evidence on the effectiveness of these two type of controls i argue that controls on outflows have been ineffective they are circumvented and breed corruption i also analyze chile s recent experience with controls on inflows and i argue that their effectiveness has been exaggerated

environmental policy incentives to adopt advanced abatement technology abstract we investigate incentives through environmental policy instruments to adopt advanced abatement technology first we study the case where the regulator makes long term commitments to policy levels and does not anticipate arrival of new technology we show that taxes provide stronger incentives than permits auctioned and free permits offer identical incentives and standards may give stronger incentives than permits second we investigate scenarios where the regulator anticipates new technologies we show that with taxes and permits the regulator can induce first best outcomes if he moves after firms have invested whereas this does not always hold if he moves first

a reconsideration of enforcement leverage when penalties are restricted abstract harrington s 1988 model of state dependent enforcement of pollution standards indicates the potential for significant reductions in monitoring cost however this approach results in firms with identical pollution cost functions polluting at different levels and thereby failing to minimize control cost for a given total pollution reduction derivations indicate that a state independent approach with a modified standard will often yield a lower sum of pollution control and monitoring cost for a given level of pollution control

the economics of controlling stock pollutants an efficient strategy for greenhouse gases abstract optimal control theory is applied to develop an efficient strategy to control stock pollutants such as greenhouse gases and hazardous waste the optimal strategy suggests that at any time the marginal costs of abatement should be equated with the present value of the marginal damage of timely unabated emission the optimal strategy calls for increasingly light abatement over time as the pollutant stock accumulates the optimal policy applied to greenhouse gases suggests moderate abatement efforts at present with the potential for much greater future efforts

enforcement costs and the optimal magnitude and probability of fines whenever the government uses fines to control harmful activities it incurs certain costs in connection with the enforcement process this article will show how these costs affect the optimal magnitude of fines and the optimal degree of enforcement effort that is the optimal probability of detection of those who commit harmful acts we will distinguish between two types of enforcement costs fixed enforcement costs are costs that do not depend on the number of individuals who commit harmful acts these costs would include for example the expenses borne by a pollution control agency in testing water quality in a lake variable enforcement costs are costs that do depend on the number of individuals who commit harmful acts such as the costs of prosecuting and penalizing polluters in our basic model we assume that the fixed enforcement costs are the costs of maintaining the probability of detection at a certain level and that the variable enforcement costs are the costs of fining individuals the main conclusions of this article may be summarized as follows the optimalfine equals the harm properly inflatedfor the chance of not being detected plus the variable enforcement cost of imposing the fine if the fine is of this magnitude the expected fine will equal the harm caused by the harmful act plus the expected increase in enforcement costs occasioned by it for instance suppose that the probability of detecting a

the lifeboat problem abstract we study an all pay contest with multiple identical prizes lifeboat seats prizes are partitioned into subsets of prizes lifeboats players play a two stage game first each player chooses an element of the partition a lifeboat then each player competes for a prize in the subset chosen a seat we characterize and compare the subgame perfect equilibria in which all players employ pure strategies or all players play identical mixed strategies in the first stage the partitioning of prizes can lead to coordination failure when players employ nondegenerate mixed strategies in these equilibria some rents are sheltered and rent dissipation is reduced

regime uncertainty and optimal investment timing abstract we construct a real options model in which a regime change is expected at a pre determined future time and study the effects of regime uncertainty on a firm s strategic investment decision taking into consideration the remaining time to the regime change and the probability of each regime state we show that just before the time of a regime change firms should act as if the worst case scenario was about to happen even if a good state is highly possible

stochastic pollution costly sanctions and optimality of emission permit banking abstract this paper identifies a new economic motive for pollution regulations that allow polluting firms to bank and borrow emission permits over time when aggregate pollution is stochastic an intertemporal permit trading regime can provide firms with efficient incentives for pollution abatement without the need for costly government enforcement actions that would otherwise be required

enforcement leverage when penalties are restricted in the united states empirical studies of the enforcement of continuous compliance with environmental regulations especially air and water pollution regulations have repeatedly demonstrated the following i for most sources the frequency of surveillance is quite low ii even when violations are discovered fines or other penalties are rarely assessed in most states iii sources are nonetheless thought to be in compliance a large part of the time the evidence for the apparently low level of enforcement activity is found in a number of case studies of state and local enforcement of air and water quality regulations conducted jointly by the environmental protection agency epa and council on environmental quality ceg together with periodic surveys of implementation of air and water quality legislation conducted by the general accounting office gao these surveys show

the externalities problem of transboundary and persistent pollution abstract this paper deals with implementing the efficient allocation of transboundary and persistent pollution in particular we adapt varian s compensation mechanism varian a solution to the problem of externalities when agents are well informed amer econ rev 85 1994 1278 1293 to cover situations in which pollutants extend to neighboring regions and their effects persist over time the main contribution of this paper is the design of a mechanism that implements in subgame perfect equilibrium the efficient pollution levels in this context

regulatory objectives and enforcement behavior economic models of enforcing environmental law have incorporated varying assumptions about regulatory objectives this paper examines the consequences of different attitudes toward the benefits and costs of pollution control on the part of regulators who have limited powers and resources we find that greater weight given to compliance costs relative to the social damages of the polluting activity will bring outcomes closer to the optimum when the regulator is strong but may move outcome further from the social optimum when regulatory powers are weak when negotiated noncompliance is an option greater consideration of compliance costs will tend to produce better results

the optimal allocation of prizes in contests we study a contest with multiple not necessarily equal prizes contestants have private information about an ability parameter that affects their costs of bidding the contestant with the highest bid wins the first prize the contestant with the second highest bid wins the second prize and so on until all the prizes are allocated all contestants incur their respective costs of bidding the contest s designer maximizes the expected sum of bids our main results are 1 we display bidding equlibria for any number of contestants having linear convex or concave cost functions and for any distribution of abilities 2 if the cost functions are linear or concave then no matter what the distribution of abilities is it is optimal for the designer to allocate the entire prize sum to a single first prize 3 we give a necessary and sufficient conditions ensuring that several prizes are optimal if contestants have a convex cost function

reasonable doubt and the optimal magnitude of fines should the penalty fit the crime models of the enforcement compliance relationship have assumed that both the probability and magnitude of fines are independent choice variables of policy makers these models indicate that it may be optimal to monitor with lowfrequency but to inflict uniformly maximal penalties for all infractions detected this article shows that if the judicial system is built on the reasonable doubt test then the penalty and the probability of conviction are not independent in particular as the penalty increases the probability of conviction falls as a result uniformly maximal penalties may actually encourage crime rather than deter it this article shows that optimal fines should rise with the severity of the infraction that is the penalty should fit the crime models of the enforcement compliance relationship generally treat both the probability and magnitude of fines as independent choice variables of the government this approach has led becker 1968 and others to conclude that it is optimal to set uniformly maximal penalties for all crimes and to set the probability of conviction at the minimum level necessary to enforce compliance with the law while this normative prescription is natural and intuitive there still remains a larger positive question of why in most nations of the world penalties are not uniformly high but rather rise with the severity of the crime one possible resolution of the positive and normative questions may lie in the fact that penalties and probabilities of conviction are not generally independent convictions are typically determined by judges or jurors who are instructed to convict only if the evidence convinces them beyond a reasonable doubt that the accused is guilty psychologists however have found that a juror s willingness to convict may be influenced by more than just the evidence jurors are very sensitive to the potential penalties that defendants may pay

incentives and problem uncertainty in innovation contests an empirical analysis contests are a historically important and increasingly popular mechanism for encouraging innovation a central concern in designing innovation contests is how many competitors to admit using a unique data set of 9 661 software contests we provide evidence of two coexisting and opposing forces that operate when the number of competitors increases greater rivalry reduces the incentives of all competitors in a contest to exert effort and make investments at the same time adding competitors increases the likelihood that at least one competitor will find an extreme value solution we show that the effort reducing effect of greater rivalry dominates for less uncertain problems whereas the effect on the extreme value prevails for more uncertain problems adding competitors thus systematically increases overall contest performance for high uncertainty problems we also find that higher uncertainty reduces the negative effect of added competitors on incentives thus uncertainty and the nature of the problem should be explicitly considered in the design of innovation tournaments we explore the implications of our findings for the theory and practice of innovation contests this paper was accepted by christian terwiesch operations management

the dynamics of optimal environmental regulation the problem of environmental control by direct regulatory restrictions on firms maximum discharge levels is examined the problem can be viewed as one of optimally selecting this upper bound and of selecting a time at which it comes into force firms are normally given time to adjust to the new regime the firm chooses a private cost minimising adjustment path and the control authority needs to take account of this in setting the regulatory control the resulting second best solution is contrasted with the first best environmental adjustment path

rivals search for buried treasure competition and duplication in r d we model an r d race in which each fi rm decides in each period between two research projects only one of which has positive success probability and it is not known which there is symmetric information and hence scope for strategic search if the prize is shared when discovery is simultaneous there is too much duplication of projects if neither is rewarded in this event then equilibrium is efficient unless projects have asymmetric costs in which case there is a bias toward the high cost project or asymmetric success probabilities in which case too little duplication is possible if one firm is informed it may choose the wrong project to put the other off the scent

pollution permits and compliance strategies abstract this paper analyzes the impact of spot and futures markets for tradeable pollution permits on the potential polluters compliance decisions polluters can buy permits invest in pollution abatement or else stop production or source out we show that stand alone spot markets induce excessive investment the introduction of a futures market reduces this incentive to invest but is not the optimal way to control pollution a menu of options on pollution rights possibly coupled with intertemporally bundled sales yields higher welfare because of its focus on long run demand elasticities and rent extraction this paper can be applied to a variety of situations such as demand side management public transportation bypass in telecommunications or forward sales by a private monopolist

preemptive search and r d clustering while many preceding studies discuss the equilibrium intensity of r d this article focuses on its equilibrium direction there can be a pure strategy equilibrium in which multiple firms cluster i e attempt to develop the same technology even if i potential technologies are ex ante equally promising ii each technology can be patented by no more than one firm and iii there are no informational spillovers among firms economic applications of this clustering result are not confined to r d any situation where agents are racing in search of exclusive economic opportunities can be an example of this model

incentives for advanced pollution abatement technology at the industry level an evaluation of policy alternatives abstract in this research we evaluate the incentive effects of five environmental policy instruments to promote the development and adoption of advanced pollution abatement technology in a heterogenous industry from most to least incentive the policy instruments can be rank ordered as follows i auctioned permits ii emissions taxes and subsidies iii issued marketable permits iv performance standards including performance standards in this list necessitates the assumption that they are differentiated between heterogeneous firms before the technology adoption in a way which replicates the initial emissions control distribution of the efficient incentive based instruments with the starting point normalized in this fashion the instrument rankings are invariant with respect to the size of firms the size of the industry or the industry s abatement cost structure

truth or consequences enforcing pollution standards with self reporting abstract evidence suggests that a surprisingly large fraction of firms comply with pollution emission standards even though expected penalties for noncompliance are low we offer an explanation of this puzzle by extending the standard model of enforcement to include a self reporting requirement and enforcement power these extensions are enough to challenge the conventional result that higher fines lead to higher compliance rates we find that under plausible conditions higher compliance rates are achieved with lower fines for noncompliance and the cost of enforcing a given level of aggregate pollution is minimized by setting the fine for noncompliance equal to zero

optimal pollution standards and non compliance in a dynamic framework in this paper we present a stackelberg differential game to study the dynamic interaction between a polluting firm and a regulator who sets pollution limits overtime at each time the firm settles emissions taking into account the fine for non compliance with the pollution limit and balances current costs of investments in a capital stock which allows for future emission reductions we derive two main results first we show that the optimal pollution limit decreases as the capital stock increases while both emissions and the level of non compliance decrease second we find that offering fine discounts in exchange for firm s capital investment is socially desirable we numerically obtain the optimal value of such discount which crucially depends on the severity of the fine in the limiting scenario with a very large severity of the fine the optimal discount implies that no penalties are levied since the firm shows adequate adaptation progress through capital investment

tournament rewards and risk taking this article considers a lazear rosen tournament model where agents can influence both the spread of their output distribution risk taking and its mean the unique equilibrium induces excessive risk taking and a low level of effort by modifying the tournament to give the highest prize to the agent with the most moderate output a low level of risk taking and high level of effort can be sustained as an equilibrium the first result can be useful to understand the relative performance evaluation puzzle of executive compensation and the second result can be useful to understand puzzling workplace norms promoting mediocrity

innovation in pollution control comparisons of the various institutional arrangements for controlling pollutant emissions from individual sources effluent fees effluent control subsidies marketable permits and direct command and control regulation have usually focused on their static efficiency properties and institutional feasibility e g dales 1968 zerbe 1970 baumol and oates 1975 kneese and schultze 1975 marin 1978 mills and white 1978 spence and weitzman 1978 russell 1979 a relatively neglected area has been the study of how each arrangement influences innovation in pollution control a few studies e g kneese and schultze 1975 marin 1978 mills and white 1978 russell 1979 have casually claimed that the control methods that rely on economic incentives provide superior incentives for innovation but there have been few systematic studies of the question this paper provides a simple model of pollution control innovation by a profitmaximizing polluter who is subject to the various control methods the consequences of the methods will be explored in three major contexts first we assume that the polluter and the innovation is a small enough part of the overall pollution problem so that none of the important marginal conditions are changed by the innovation second we assume that the polluter and the innovation are important enough so that marginal conditions are changed by the innovations but that the governmental authority determining pollution control incentives or levels fails to make the appropriate adjustments third we again assume that the innovation causes marginal conditions to change but in this case the governmental authority makes the appropriate adjustments we use the term ratcheting to describe this last phenomenon in all cases we assume that the innovating polluter correctly predicts the reactions of the governmental authority and bases his innovation decisions on that prediction a profit maximizing entrepreneur would normally be expected to adopt any innovation that promised gains present discounted value to him in excess of initial

risk taking in selection contests abstract we study contests where the strategic variable is the degree of risk taking rather than the amount of effort the selection efficiency of such contests is examined we show that the selection efficiency of a contest may be improved by limiting the competition in two ways by having a small number of contestants and by restricting contestant quality

dynamic incentives by environmental policy instruments a survey abstract in this paper i survey and discuss recent developments on the incentives provided by environmental policy instruments for both adoption and development of advanced abatement technology a main conclusion to be drawn from the literature is that under competitive conditions market based instruments usually perform better than command and control moreover taxes may provide stronger long term incentives than tradable permits if the regulator is myopic if the government can anticipate new technology or is able to react on it optimally regulatory policies by virtue of administered prices taxes and policies by setting quantities issuing tradable permits are almost equivalent the literature also shows that under competitive conditions there is no difference between auctioning permits and grandfathering moreover timing and commitment of environmental policy is not crucial for adoption under competitive conditions commitment has positive incentive effects however if an r d sector has market power in the presence of market imperfections the ranking of the different policy instruments is ambiguous

capital control liberalization and stock market development the authors address two questions what happens to stock market size liquidity volatility and integration with world capital markets after capital controls are liberalized and what is the relationship between those indicators of stock market development and regulations about information disclosure accounting standards and investor protection an analysis of data on stock markets in 16 developing countries suggests the following a stock markets become larger more liquid more integrated internationally and more volatile after controls on capital and dividend flows are liberalized b easy access to information about firms is positively associated with the size and liquidity of stock markets and c countries that officially establish internationally accepted accounting standards and laws to protect investors do not have substantially better functioning stock markets than countries that do not adopt those official standards

capital controls and stock market volatility in frequency domain abstract the link between capital controls and stock market volatility is examined using frequency domain techniques conventional analyses of the second moments can produce spurious results if the high frequency volatility is reduced increased while the overall volatility is increased reduced

stopping hot money abstract while high interest rates and foreign exchange sales are the most common way of dealing with a speculative attack in the foreign exchange market several countries resorted to capital controls during recent periods of currency market turbulence the purpose of this study is to use daily financial data to examine three of these capital controls episodes brazil 1999 malaysia 1998 and thailand 1997 we aim to assess the extent to which the capital controls were effective in delivering the outcomes that motivated their inception in the first place we conclude that in two of the three cases brazil and thailand the controls did not deliver much of what was intended although one does not observe the counterfactual by contrast in the case of malaysia the controls did align closely with the priors of what controls are intended to achieve greater interest rate and exchange rate stability and more policy autonomy

optimal management of durable pollution abstract we study an incompletely informed regulator s problem of inducing a firm producing durable pollution to manage its pollution optimally we show the existence of an optimal regulatory contract our principal qualitative result is that the optimal contract in this setting induces an inefficiently large amount of emission relative to the outcome under pigovian regulation or full information our sparse yet flexible model of the firm can be applied directly in concrete settings as it is stated in terms of statistical parameters moreover it generates useful information about the firm that has to be assumed in an abstract regulatory model

to comply or not to comply pollution standard setting under costly monitoring and sanctioning in this paper we characterize optimal regulatory policies composed of a pollution standard a probability of inspection and a fine for non compliance in a context where both monitoring and sanctioning are socially costly and the penalty may include gravity and non gravity components at the regulator s discretion under given penalties the optimal policy entails compliance with the standard as long as a quite intuitive condition is met non compliant policies may include standards even below the pollution levels that minimize the sum of abatement costs and external damages interestingly the appropriate structure of the penalty under non compliance is highly progressive while the best possible shape of the fine under compliance is linear if the regulator is entitled to choose the structure of the fine linear penalties are socially preferred and the optimal policy induces compliance
