fuzzy multi objective approach for optimal selection of suppliers and transportation decisions in an eco efficient closed loop supply chain network abstract establishment of a closed loop supply chain clsc network has attracted immense significance due to government policies and societal demand for environmental consciousness however to enhance the financial and ecological impact of the network the forward and reverse supply chain networks must integrate well so that decisions taken in both areas complement each other in this study we propose an eco efficient clsc design for extending the existing supply chain of an indian firm that assembles inkjet printers the network design is configured as a multi objective model in a multi period setting and is mathematically formulated into a mixed integer programming problem with fuzzy objectives fuzziness provides flexibility to the decision makers because they must accommodate the conflicting nature of the objectives the fuzzy multi objective model incorporates the firm s economic and environmental concerns into the decision making process by selecting environmentally responsible suppliers to procure components based on sustainable criteria choosing appropriate recovery options for end of use eou inkjet printers and planning an efficient transportation network design for reducing the carbon emission of the distribution and collection activities the uniqueness of the proposed fuzzy clsc optimization model lies in providing an integrated decision making framework that can aid the manufacturer in making crucial strategic tactical and operational decisions of optimal selection of suppliers component order allocation recovery flow allocation and vehicle routing planning the novelty of the model also lies in simultaneously minimising the overall cost of the activities undertaken maximizing the performance of the component suppliers and minimising the carbon emissions of the associated transportation activities a weighted fuzzy mathematical programming approach is utilised for generating a fuzzy properly efficient solution as the desired compromised solution for the clsc network problem configuration the relevance of the model is justified using a real data set derived from a case study of the firm based in the northern capital region ncr of india the findings indicate that the proposed integrated clsc network model enables the firm in gaining sustainably from the numerous electronic product reuse opportunities in the indian market further while costly to begin with choosing suppliers with higher sustainable performance and vehicles with lesser emission rate could substantially enhance firm s sustainable image and result in higher profits in the future

using a policy mix for pollution control a review of economic literature this article provides a review of economic studies analyzing the use of multiple policies a socalled policy mix to cope with single pollution problems to guide and structure the review an analytical framework is developed and applied the framework integrates transaction costs into the analysis of pollution problems and policies to overcome them moreover it understands a pollution externality not only as a market failure but more generally as the failure of private governance structures based on this insight two rationales for using a policy mix are identified first a policy mix may help to correct for multiple reinforcing failures of private governance structures such as pollution externalities and technological spillovers second a policy mix can be employed if the implementation of single first best policies brings about high transaction costs e g when marginal pollution damages are heterogeneous or polluters are unlikely to comply with the policy for each rationale the relevant literature is presented based on the review avenues for future research are identified

the socially optimal recycling rate evidence from japan this paper estimates the average social cost of municipal waste management as a function of the recycling rate social costs include all municipal costs and revenues costs to recycling households to prepare materials estimated with an original method external disposal costs and external recycling benefits results suggest average social costs are minimized with recycling rates well below observed and mandated levels in japan cost minimizing municipalities are estimated to recycle less than the optimal rate these results are robust to changes in the components of social costs indicating that japan and perhaps other developed countries may be setting inefficiently high recycling goals

economic efficiency effects of alternative policies for reducing waste disposal abstract reducing the amount of municipal solid waste that is disposed of has become an important policy goal previous research argued that a virgin material tax offered an efficient method of meeting this goal and it continues to be considered as a policy option today this paper demonstrates however that a virgin material tax is not an efficient method of reducing waste but that an alternative policy a combined disposal tax and reuse subsidy is the combined disposal tax and reuse subsidy is theoretically consistent with unit based household charges for waste disposal but may have advantages in some situations

scrap prices waste and recycling policy this study examines the effect of waste and recycling policy on scrap prices and the importance of scrap price feedbacks as a determinant of policy costs price effects and direct and indirect channels of waste reduction are decomposed for deposit refund advance disposal fee and recycling subsidies scrap price feedbacks decrease the cost of advance disposal fees increase the cost of recycling subsidies and have an ambiguous effect on the cost of deposit refund simulation analysis finds that scrap price feedbacks substantially affect the costs of the policies and alter the ranking of instruments jel q53 q58

truthfulness in accounting how to discriminate accounting manipulators from non manipulators accountants preparing information are in a position to manipulate the view of economic reality presented in such information to interested parties these manipulations can be regarded as morally reprehensible because they are not fair to users they involve in an unjust exercise of power and they tend to weaken the authority of accounting regulators this paper develops a model for detecting earnings manipulators using financial statements ratios in a sample of spanish listed companies our results provide evidence that accounting data can be extremely useful in detecting manipulators this approach can be used by a large category of users of accounting information among which we can cite stock exchange supervisors or investing professionals

do central banks respond to exchange rate movements a structural investigation abstract we estimate a small scale structural general equilibrium model of a small open economy using bayesian methods our main focus is the conduct of monetary policy in australia canada new zealand and the uk we consider generic taylor type rules where the monetary authority reacts in response to output inflation and exchange rate movements we perform posterior odds tests to investigate the hypothesis whether central banks do target exchange rates the main result of this paper is that the central banks of australia and new zealand do not whereas the bank of canada and the bank of england do include the nominal exchange rate in its policy rule this result is robust for various specification of the policy rule we also find that terms of trade movements do not contribute significantly to domestic business cycles

on the dynamics of recycling and natural resources we study the dynamic impact of recycling through its effect on the production set of the economy and its relationship with natural resources the contribution of renewable and recyclable resources for sustainability is studied although in the short run recycling may alleviate resource scarcity in the long run it is not enough to compensate for the exhaustibility of non renewable resources and the possibility of obtaining non decreasing output paths crucially depends on the extent to which production rests on renewable resources furthermore recycling interacts with natural resource growth surprisingly not always favoring sustainability the production and recycling function is a generalization of the traditional production function providing an integrated view of regular production and recycling and representing the production set of the economy when a recycling technology is available

cultural influence on the development of accounting systems internationally a test of gray s 1988 theory this paper attempts to test the theory developed by gray 1988 linking accounting values and systems with hofstede s 1980 cultural constructs based on data from twenty nine countries it finds that while gray s 1988 model has statistically significant explanatory power it is best at explaining actual financial reporting practices and is relatively weak in explaining extant professional and regulatory structures from a cultural base this paper further finds that both the development of financial markets and levels of taxation enhance the explanations offered by gray 1988

trade in and save a two period closed loop supply chain game with price and technology dependent returns abstract consumers evaluate the convenience of changing their products according to the price paid as well as the technology quality level when the consumers wish to capitalize the products residual value they should return them as early as possible accordingly we develop a model of closed loop supply chain clsc where consumers seek to gain as much as possible from their returns and the return rate is a function of both price and quality we model a two period stackelberg game to capture the dynamic aspects of a clsc where the manufacturer is the channel leader we investigate who namely manufacturer or retailer should collect the products in the market thus we identify the best clsc structure to adopt when the return rate is both price and quality dependent our results demonstrate that it is always worthwhile for companies to collect products and adopt an active return approach for returns we investigate the effect of retail competition in both forward and backward channels and show the impact of eliminating the double marginalization on market outcomes

the time varying nairu and its implications for economic policy the nairu the unemployment rate consistent with a constant rate of inflation is estimated in this paper as a parameter allowed to vary over time value is determined in an econometric model where the inflation rate depends on its past values demand and supply shocks the nairu estimated for the gdp deflator varies over the past forty years within 5 4 to 6 5 percent its estimated value for the most recent quarter 1996 q2 is 5 6 percent the nairu has declined in recent years in response to global competition immigration other factors weakening labor s bargaining position and the rapidly declining prices of computers and other electronics

cultural influences on managerial choice an empirical study of employee benefit plans in the united states the objective of this study is to determine the effect of culture on the provision of employee benefits cultural influences have been investigated from a variety of perspectives but not in the context of pension and welfare benefits using unique data this study analyzes the level of coverage of employee benefits in the united states results indicate that culture does have an effect on the provision of these benefits

converting technology to mitigate environmental damage there are many situations where policy makers would like to induce firms to make a major discrete conversion in production technology to help the environment this paper examines how heterogeneity in the operating condition of firms plant and equipment which cannot be observed by policy makers can affect the choice between incentives to encourage conversion to a cleaner technology by relating different conditions of firms plant and equipment to production costs extent of environmental damage and cost of conversion to a cleaner technology we show when a perfectly discriminating incentive to encourage conversion is not feasible in addition we show that firms with plant and equipment in better condition will convert their technology to mitigate their environmental damage and firms with plant and equipment in poorer condition will not this and a series of additional results lead to conditions under which an administratively simple uniform lump sum incentive to switch to cleaner technology is preferable to one based on output these results and conditions extend to cases where there are network externalities in conversion and where there is strategic timing in firms choice of when to convert

nationality and subsidiary ownership patterns in multinational corporations this paper examines the notion that the multinational s nationality influences its foreign subsidiary ownership decisions it identifies theoretically meaningful constructs to represent nationality and examines under carefully controlled conditions their influence on subsidiary ownership preferences in american and european multinationals the paper concludes that there are indeed significant differences in ownership preferences among various nationalities that can be explained using cultural as well as economic variables but that these differences may become weaker in larger multinationals

an experimental investigation into cross national mail survey response rates this study investigates the effects of foreign and domestic source manipulations on cross national response rates of business people in two countries the united states and britain the hypothesis that managers from the u s a are more likely to respond than those from britain is also tested results suggest that foreign source effects do not raise response rates for british managers findings suggest that higher compliance results from the domestic source responses from usa managers were no higher than from their british counterparts the implications of these findings for cross national mail surveys are discussed

strategic response to pollution taxes in supply chain networks dynamic spatial and organizational dimensions abstract this paper presents a model of the strategic behavior of firms operating in a spatial supply chain network the manufacturing and retailing firms engage in an oligopolistic noncooperative game by sharing customer demand such that a firm s decisions impact the product prices which in turn result in changes in all other firms decisions each firm s payoff is to maximize its own profit and we show that in response to such changes in prices and to exogenous environmental taxes the manufacturing firms may strategically alter a variety of choices such as make buy decisions with respect to intermediate inputs spatial distribution of production product shipment patterns and inventory management environmental tax payment vs recycling decisions and timing of all such choices to sustainably manage the profit and the environmental regulations an important implication is that effects of a tax depends on the oligopolistic game structure with respect to methods we show that this dynamic game can be represented as a set of differential variational inequalities dvis that motivate a computationally efficient nonlinear complementarity ncp approach that enables the full exploitation of above mentioned salient features we also provide a numerical example that confirms the utility of our proposed framework and shows substantial strategic reaction can be expected to a tax on pollution stocks

garbage recycling and illicit burning or dumping abstract with garbage and recycling as the only two disposal options we confirm prior results that the optimal curbside fee for garbage collection equals the direct resource cost plus external environment cost when illicit burning or dumping is a third disposal option that cannot be taxed directly the optimal curbside tax on garbage changes sign the optimal fee structure is a deposit refund system a tax on all output plus a rebate on proper disposal through either recycling or garbage collection the output tax helps achieve the first best allocation even though it affects the choice between consumption and untaxed leisure

governance mechanisms of dual channel reverse supply chains with informal collection channel abstract the existence of informal collection channel has been a serious problem for reverse supply chain management in china informal collectors interrupt the normal order of end of life product collection to assess this problem this article explores governance mechanisms of the current recycling system in practical operations from the perspectives of both governments and enterprises based on the respective characteristics of two collection channels i e formal and informal we establish a stackelberg game model to describe and analyze the dual channel collection supply chain in which consumer preference to collection channels is considered based on the benchmark model three governance mechanisms set by both governments and formal collectors are introduced and analyzed when deriving optimal decisions and certain parameter properties this study demonstrates that both governments and collectors can implement appropriate governance mechanisms to control or utilize the informal collection channel under different circumstances on one hand on the other hand governance mechanisms set by the government are unenforceable to control informal collection under certain situations the effectiveness of governance mechanisms is determined based on different channel preferences of consumers and the economic value of the waste electrical and electronic equipment weee

assessing the effects of culture on managerial attitudes a three culture test cross cultural studies are inherently difficult because the typical research design fails to differentiate cultural from other environmental influences the present study uses a research design that attempts to isolate the influence of culture japanese chinese and mexican managers their ethnic american counterparts and anglo americans are used to test the model results indicate unique persistent cultural characteristics with the cultural effect varying among the three groups of managers

revaluing the hierarchy of paper recycling this article revalues the hierarchy of paper waste management policies in a dynamic general equilibrium model incineration material recycling and the distinction between non renewable fossil fuels and renewable forest assets are incorporated by comparing the first order conditions from the command optimum with the conditions from the market model it is discovered that the unregulated market fails to create an optimal resource allocation to see how the market behaves in absence of environmental policy compared to the first best solution a numerical model is used pigouvian taxes and subsidies are derived to correct for the externalities

sustainable sc through the complete reprocessing of end of life products by manufacturers a traditional versus social responsibility company perspective abstract every item produced transported used and discarded within a supply chain sc generates costs and creates an impact on the environment the increase of forward flows as effects of market globalization and reverse flows due to legislation warranty recycling and disposal activities affect the ability of a modern sc to be economically and environmentally sustainable in this context the study considers an innovative sustainable closed loop sc problem it first introduces a linear programming model that aims to minimize the total sc costs environmental sustainability is guaranteed by the complete reprocessing of an end of life product the re use of components the disposal of unusable parts sent directly from the manufacturers with a closed loop transportation system that maximizes transportation efficiency secondly the authors consider the problem by means of a parametrical study by analyzing the economical sustainability of the proposed clsc model versus the classical forward supply chain model fwsc from two perspectives case 1 the traditional company perspective where the sc ends at the customers and the disposal costs are not included in the sc and case 2 the social responsibility company perspective where the disposal costs are considered within the sc the relative impact of the different variables in the sc structure and the applicability of the proposed model in terms of total costs sc structure and social responsibility are investigated thoroughly and the results are reported at the conclusion of the paper

exhaustible resources and secondary materials a macroeconomic analysis abstract in this paper we have developed an endogenous growth model to deal with exhaustible resources and secondary materials together under the assumptions that these two inputs are or are not technologically perfect substitutes of each other in order to compare the results obtained under both hypotheses we highlight the implication of these two assumptions on the rate of growth of total output and upon the flow of exhaustible resources extracted there are also some other interesting findings related to the spill over on welfare of the waste recycling process and the dynamics of shadow prices of both inputs considered finally some implications on hotelling s rule also emerge in our analytical framework

upstream pollution downstream waste disposal and the design of comprehensive environmental policies abstract many policymakers are shifting their focus from media specific pollution problems to product specific life cycle environmental problems in this paper we develop a model of production and consumption that incorporates life cycle externalities and use it to solve for alternative policies to achieve a social optimum in general we find that no single instrument can solve multiple problems contrary to what some observers have suggested however we find that there are alternative ways of reaching the social optimum we also discover that an integrated approach to policy appears to be important no matter what policy options are adopted and finally we find that there is only a limited role for so called product life cycle assessments

does religion mitigate earnings management evidence from china using a sample of 11 357 firm year observations from the chinese stock market for the period of 2001 2011 we investigate whether and how religion can mitigate earnings management specifically based on geographic proximity based religion variables we provide strong and robust evidence to show that religion is significantly negatively associated with the extent of earnings management suggesting that religion can serve as a set of social norms to mitigate corporate unethical behavior such as earnings management our findings also reveal that the negative association between religion and earnings management is less pronounced for firms with closer distance to the regulatory centers than for their counterparts implying the substitutive effects between religion and the distance to regulators the proxy for regulatory intensity on mitigating earnings management the above results are robust to different measures of earnings management various religion variables and a variety of sensitivity tests

avoiding uncertainty in hofstede and globe this paper compares the uncertainty avoidance ua dimension of national culture across the hofstede and globe models looking at relationships in both data and analysis rather than mutual support we detail major differences and anomalies across the studies we show how these anomalies are resulting in contradictory explanations in research on national differences across a range of individual firm and country level phenomena we clarify the ua measurement in both hofstede and globe and find that the two models are measuring different components of the ua construct we propose a two component model of ua namely ua stress and ua rule orientation and confirm its validity with national culture data from the hofstede and globe studies and economic data from the world bank we also explain the negative globe ua practices values relationship using motivational theories a way forward in future ua related research is suggested the hofstede ua index the globe ua practices scores and the globe ua values scores should be used within the specific domains that they represent that is stress rule orientation practices and rule orientation aspirations respectively resolving the contradictions in ua between and within hofstede and globe will help cross cultural researchers develop more robust theories and more practical recommendations for international business management

debt covenant violation and manipulation of accruals abstract this paper examines the abnormal accruals of a sample of 94 firms that reported debt covenant violations in annual reports we expect debt covenant restrictions to influence accounting choices in the year preceding and the year of violation time series and cross sectional models are used to estimate normal accruals in the year prior to violation both models indicate that abnormal total and working capital accruals are significantly positive in the year of violation there is evidence of positive abnormal working capital accruals after controlling for management changes and auditor going concern qualifications

a comparison of public policies for lead recycling policies that encourage recycling may be used to reduce environmental costs from waste disposal because direct restrictions on disposal are difficult to enforce four recycling policies have been advanced i taxes on the use of virgin materials ii deposit refund programs iii subsidies to recycled material production and iv recycled content standards in this article i analyze the structure of these policies and their cost effectiveness in achieving reductions in disposal i then examine the policies in the empirical context of the recycling of lead from automobile batteries in order to calculate the effects of recycling programs i estimate the elasticities for primary and secondary lead supply and demand my results suggest that price based policy mechanisms can be successful in increasing lead recovery and that the difference in efficiency between the four approaches is similar

does international harmonization of environmental policy instruments make economic sense harmonization of the instruments used in environmental policy has beenconsidered necessary to guarantee fair competition in internationalmarkets we examine the economic costs of harmonizing paper recyclingstandards in countries where the urgency of the waste disposal problemsdiffer using data of seven european countries we estimate thetechnologically feasible input combinations of pulp and waste paper forpaper production short term effects of two environmental policy measures minimum content requirement and utilization rate target are analyzed bytranslating the two administrative instruments into taxes and subsidies weshow that the shadow costs of the harmonization vary considerably betweencountries the difference in the domestic availability of waste may explainthe variation and a modification of the policy measures to incorporate thisaspect is suggested

on the second best policy of household s waste recycling this study analyzes the second best household s waste recycling policy if we assume the first best economy with no illegal disposal or transaction costs then unit pricing an advance disposal fee and a recycling subsidy are required in order to achieve the social optimum such that both the sum of unit pricing and an advance disposal fee and the sum of unit pricing and a recycling subsidy are equal to the marginal disposal cost furthermore the first best outcome can also be obtained by a producer take back requirement system in the real economy however various factors prevent the first best optimal outcome in this study we consider two factors one being the transaction cost associated with a recycling subsidy or refund and the other being illegal disposal by the consumer if a recycling subsidy or a deposit refund system is adopted a transaction cost associated with it will be generated alternatively if unit pricing is adopted some of the consumed goods may be disposed of illegally we show the complete trade off between unit pricing and a recycling subsidy in other words we can not adopt unit pricing and a recycling subsidy simultaneously as a result there are three candidates for the second best policy unit pricing with an advance disposal fee a deposit refund system and a producer take back requirement system which of these three policies is the second best policy will depend on the relative magnitude of the price of a recycled good and the marginal transaction cost associated with a recycling subsidy or the refund in a deposit refund system generally if the price of a recycled good is positive and the marginal transaction cost is relatively high unit pricing with an advance disposal fee is the second best policy however where the price of a recycled good is negative and the marginal transaction cost is relatively high a producer take back requirement system is the second best policy further where the marginal transaction cost is relatively low a deposit refund system is the second best policy regardless of whether the price of a recycled good is positive or negative

no return no refund an analysis of deposit refund systems firms and governments in developed economies frequently employ deposit refund systems to promote return and reuse of product packages and containers we analyze a model of monopoly facing heterogeneous consumers in which recycling package return by consumers generates an external benefit it is shown that when consumer s preferences over recycling differ the monopolist can price discriminate between consumers leading to socially suboptimal recycling in the absence of any externalities the analysis can be viewed as a model of couponsor mail in rebateswhich work as price discrimination devices the role of government subsidies and additional deposits to eliminate suboptimal recycling is also analyzed finally the model is extended to incorporate hustling i e allowing consumers to recycle packages discarded by other consumers 2001 elsevier science

monetary policy rules based on real time data this paper examines the magnitude of informational problems associated with the implementation and interpretation of simple monetary policy rules using taylor s rule as an example i demonstrate that real time policy recommendations differ considerably from those obtained with ex post revised data further estimated policy reaction functions based on ex post revised data provide misleading descriptions of historical policy and obscure the behavior suggested by information available to the federal reserve in real time these results indicate that reliance on the information actually available to policy makers in real time is essential for the analysis of monetary policy rules

closed loop supply chain network equilibrium under legislation this paper expands previous work dealing with oligopolistic supply chains to the field of closed loop supply chains the model presented has been formulated with the intent of examining issues surrounding the recent european union directive regarding waste of electric and electronic equipment weee the network modelled consists of manufacturers and consumer markets engaged in a cournot pricing game with perfect information closed loop supply chain network equilibrium occurs when all players agree on volumes shipped and prices charged certain properties of the model are examined analytically numeric examples are included and have been solved using an extragradient method with constant step size the equilibrium solution obtained provide interesting insights that lead into a number of areas for future research

how robust is the fed reaction function to changes in the output gap specification using alternative measures of the output gap we estimate a forward looking monetary policy reaction function similar to those estimated by clarida et al 1998 2000 for greenspan s period as a chairman of the board of governors of the us federal reserve system we are able to show that the reaction function that considers an output gap based on the industrial production index instead of the unemployment rate better captures the behaviour of the federal reserve during greenspan s period

recovery decisions of a producer in a legislative disposal fee environment the main objectives of the environmental legislation originating from extended producer responsibility epr principle are to lead producers to undertake recovery initiatives for their end of use products and to promote environmentally desirable product design it is still controversial whether current implementations of epr principle are effective in attaining these objectives this study seeks to answer the following questions 1 what is the impact of epr legislation on the product recovery decisions of producers 2 how do the redesign opportunities i e design for disassembly affect the willingness of producers for product recovery 3 how do the investment needs to start recovery practices and the reluctance of producers to allocate sufficient funds for this purpose affect the optimal recovery decisions we use stylized economic models to represent the implementation in practice and solving our models we obtain closed form and numerical solutions that help us to see the impact of various parameters on the optimal decisions of a producer our findings indicate that redesign opportunities encourage producers for more recovery however the reluctance of producers to cover the initial investments may substantially reduce the effectiveness of the legislation and the recovery amounts

recognizing ethical issues an examination of practicing industry accountants and accounting students it has long been recognized that accountants practicing in business settings have a dual role 1 as employees they are bound to the organization and 2 as professionals they are bound by the profession s code of ethical conduct westra journal of business ethics 5 2 119 128 1986 these two roles highlight the need to recognize and consider both the ethical and economic implications of their decisions practicing industry accountants are commonly involved in a broad range of their firm s business practices and decision making and are increasingly exposed to the commercial aspects of their companies also during their education they were trained on their professional responsibilities however in general this education was not recent and may not have been reinforced by contrast accounting students have been recently and repeatedly exposed to and have knowledge about their professional responsibilities as an accountant but limited if any exposure to the commercial aspects of business consequently our first hypothesis predicts that the ethical sensitivity of practicing industry accountants will be lower than that of accounting students we find limited support for this hypothesis second we also examine company reward structure and predict that ethical sensitivity will be lower for those in a company with a reward structure narrowly focused only on financial goals as compared to those in a company with a broad reward structure e g including rewards for both financial and non financial goals third we predict that the difference in ethical sensitivity levels between those in a company with a narrow reward structure as compared to those in a company with a broad financial reward structure will be higher for practicing industry accountants compared to accounting students results from our study generally support these last two predictions ethical sensitivity is lower for those in a company with a reward structure narrowly focused only on financial goals as compared to those in a company with a broad reward structure suggesting that companies may be able to increase ethical awareness in their organizations by including non financial goals in their reward structures

product design and efficient management of recycling and waste treatment abstract using a general equilibrium model where material is first extracted then used for producing a consumption good recycled and finally treated to reduce environmental damage we study efficiency restoring policies when one or more of the constituent markets are inactive the material is modeled as being embodied in the output and forms an important aspect of green product design if all markets for embodied material per unit output fail and if recycling benefit exceeds environmental damage the policy instruments needed for green design are a tax on the consumption good supply and a subsidy on the demand for material input

a theory of corporate scandals why the usa and europe differ a wave of financial irregularity in the usa in 2001 2 culminated in the sarbanes oxley act a worldwide stockmarket bubble burst over this same period with the actual market decline being proportionately more severe in europe yet no corresponding wave of financial scandals involving a similar level of companies occurred in europe given the higher level of public and private enforcement in the usa for securities fraud this contrast seems perplexing this paper submits that different kinds of scandals characterize different systems of corporate governance in particular dispersed ownership systems of governance are prone to the forms of earnings management that erupted in the usa but concentrated ownership systems are much less vulnerable instead the characteristic scandal in such systems is the appropriation of private benefits of control this paper suggests that this difference in the likely source of and motive for financial misconduct has implications both for the utility of gatekeepers as reputational intermediaries and for design of legal controls to protect public shareholders the difficulty in achieving auditor independence in a corporation with a controlling shareholder may also imply that minority shareholders in concentrated ownership economies should directly select their own gatekeepers copyright 2005 oxford university press

one without the other behavioural and incentive policies for household waste management this paper provides a review of economic studies that analyses the use of multiple policies to cope with waste management problems we discuss the factors that influence selective sorting behaviour and the most appropriate policies for their promotion based on the works analysed our survey shows the original features of waste as an environmental problem requiring regulation the traditional approach in which decisions respond to rational behaviour particularly cost savings has some limits although not all public policies seem justified we argue that there might be a need for specific policies to promote recycling preferably based on the provision of information to consumers or on behavioural instruments indeed personal factors specific to each individual such as emotions and the influence of social interaction should be taken into account in the development of public policies we review the literature related to different rationales and identify some avenues for future research

when and for whom would e waste be a treasure trove insights from a network equilibrium model of e waste flows electrical and electronic equipment waste e waste is growing fast due to its potential economic value as well as its possible negative impacts on the environment tracing e waste flow is a major concern for stakeholders of e waste management especially whether or not adequate amounts of electrical and electronic equipment waste weee flow into the designed recycling systems is a fundamental issue for sustainable operations in this paper we analyze how technical market and legislative factors influence the total amount of e waste that is collected recycled exported and legally and illegally disposed off we formulate the e waste network flow model as a variational inequality problem the results of the numerical examples highlight the importance of considering the interaction between the supply and the demand side for precious materials in policy decisions low collection rates of e waste lead to low profits for stakeholders and make it difficult to establish sustainable recycling operations increasing weee collection rates increases recyclers profits however it only increases smelters profits up to a certain limit after which smelters cannot benefit further due to limited demand for precious materials furthermore the results emphasize the importance of establishing international control regimes for weee flows and reveal possible negative consequences of the recent trend of dematerialization more precisely product dematerialization tends to decrease recyles and smelters profits as well as to increase the outflow of e waste from the designated recycling system authors abstract

greenhouse gas emissions waste and recycling policy abstract this paper examines least cost policies for waste reduction incorporating upstream greenhouse gas externalities associated with the production of consumption goods from various materials in particular we decompose the effect of deposit refund advance disposal fees and recycling subsidies on upstream greenhouse gas emissions we find that the benefits of reducing greenhouse gas emissions are of the same order as or larger than the benefits of reducing solid waste disposal implying larger optimal total waste reduction than previous studies furthermore the least cost intervention levels will be material specific and vary substantially across materials finally despite the reductions in emissions implied by increased recycling rates direct recycling subsidies are more costly and generate less emissions reductions than a deposit refund or advance disposal fee

national culture economic development population growth and environmental performance the mediating role of education literature on ethical behavior has paid little attention to the mechanism between macro environmental variables and environmental performance this study aims at constructing a model to examine the relationships which link cultural values population growth economic development and environmental performance by incorporating the mediating role of education the multiple linear regression model was employed to test the hypotheses on a 3 year pooled sample of 51 countries empirical results conclude that national culture economic development and population growth would significantly influence environmental performance directly in addition through the mediating effect of education population growth and national culture would significantly affect environmental performance indirectly these findings provide theoretical and managerial implications for constructing the mechanism of cultural values and ethical behavior in general and environmental management in particular

the nairu unemployment and monetary policy this paper examines the precision of conventional estimates of the nairu and the role of the nairu and unemployment in forecasting inflation the authors find that although there is a clear empirical phillips relation the nairu is imprecisely estimated forecasts of inflation are insensitive to the nairu and there are other leading indicators of inflation that are at least as good as unemployment this suggests deemphasizing the nairu in public discourse about monetary policy and instead drawing on a richer variety of leading indicators of inflation

cultural and ethical effects in budgeting systems a comparison of u s and chinese managers this study developed and tested a model of culture s effect on budgeting systems and hypothesized that system variables and reactions to them are influenced by culture specific work related and ethical values most organizational and behavioral views of budgeting fail to acknowledge the ethical components of the problem and have largely ignored the role of culture in shaping organizational and individual values cross cultural differences in reactions to system design variables and in the behaviors motivated or mitigated by those variables has implications for the design and effectiveness of budgeting systems the data largely support our research model demonstrating the hypothesized national cultural differences in system design variables e g participation standards tightness budget emphasis etc which we characterized as the opportunity and incentives to create budgetary slack and the expected relationship between incentives but not opportunity to create slack and slack creation behavior the data demonstrate hypothesized cultural differences in ethical ideology but show ethical ideology related to slack creation behavior only for u s managers a discussion of the results and their implications is included

efficient implementation of collective extended producer responsibility legislation extended producer responsibility epr is a policy tool that holds producers financially responsible for the post use collection recycling and disposal of their products many epr implementations are collective a large collection and recycling network crn handles multiple producers products in order to benefit from scale and scope economies the total cost is then allocated to producers based on metrics such as their return shares by weight such weight based proportional allocation mechanisms are criticized in practice for not taking into account the heterogeneity in the costs imposed by different producers products the consequence is cost allocations that impose higher costs on certain producer groups than they can achieve independently this may lead some producers to break away from collective systems resulting in fragmented systems with higher total cost yet cost efficiency is a key legislative and producer concern to address this concern this paper develops cost allocation mechanisms that

optimal co investment in supply chain infrastructure abstract this paper considers co investment in a supply chain infrastructure using an inter temporal model we assume that firms capital is essentially the supply chain s infrastructure as a result firms policies consist in selecting an optimal level of employment as well as the level of co investment in the supply chain infrastructure several applications and examples are presented and open loop as well as feedback solutions are found for non cooperating firms long and short run investment cooperation and non simultaneous moves stackelberg firms in particular we show that a solution based on nash and stackelberg differential games provides the same level of capital investment thus selecting the leader and the follower in a co investment program does not matter we show that in general co investments by firms vary both over time and across firms and thereby render difficult the implementation of co investment programs for future capital development to overcome this problem we derive conditions for firms investment share to remain unchanged over time and thus be easily planned

the effect of bottle laws on income new empirical results eleven us states have bottle laws deposit refund programs that combine a consumption tax with a recycling rebate when states set the bottle deposit low enough it becomes a tax on high wage earners for whom the opportunity cost of their time prevents them from returning containers for their deposit however this bottle deposit will still be high enough that harvesting recyclables provides employment for low wage earners using individual data on observed cash recycling behavior this paper shows that an unintended consequence of bottle laws is that they have the potential to increase the incomes of very low wage workers

a supply chain network economic model with time based competition abstract this paper presents an integrated model for time cost competition between supply chains with heterogeneous customers the firms in our model can offer various time options for their production service to time sensitive customers this gives rise of a new concept of time based supply chain which we call t chain to be the basic element in the competition and extends the inter supply chain competition to a new dimension of time assuming the customers are heterogeneous in time cost bi criteria decision making we integrate the discrete choice theory into supply chain network competition and formulate the equilibrium conditions as a multinomial logit based variational inequality problem numerical examples are presented for model illustration and managerial insights such as profit maximization for a firm who participates in this supply chain network

economic instruments and induced innovation the european policies on end of life vehicles abstract the paper addresses the mechanisms by which specific economic instruments based on the producer responsibility principle prp can influence innovation when environmental policy has impact on very complex industrial subsystems we consider the eu policy on end of life vehicles directive 2000 53 ec on elvs as a representative case study of multiple industry prp instrument dynamic efficiency problems in order to achieve ambitious policy targets on elv recovery recycling reuse interrelated sequences of single innovations in both upstream car making and downstream car recycling recovery should take place we explore the extent to which the introduction of a free take back ftb instrument can influence industrial actors in contributing to innovation paths that are still marked by technological uncertainty evolving capabilities and different cost benefit balances for actors themselves we conclude that differently from static approaches in which the ei and its formulation is neutral with respect to policy effectiveness the dynamic efficiency of eis in elv like problems depends both on where along the production to waste chain and how in terms of net cost allocation the specific incentive is introduced consequently in order to generate a policy desired innovation path the way in which the ei related incentive allocated to a certain industry is transmitted to other industries whether upward or downward along the chain is also relevant disregarding these effects can imply a dissipation of innovation incentives and the generation of regulation induced rents for some actors cannot be ruled out policies based on prp should consider eis in conjunction with enforceable voluntary agreements

closed loop supply chains under reward penalty mechanism retailer collection and asymmetric information abstract being motivated by the issue of waste electrical and electronic equipment weee collection we consider a contract design problem for a manufacturer with entrusting the collection of weee to a retailer however the manufacturer has asymmetric information on the collection effort level of the retailer this paper designs an information screening contract for the manufacturer to obtain the information of collection effort level and the optimal decision making with several properties of contract parameters are derived the results indicate that the manufacturer would offer lower wholesale price and higher buy back price for the h type retailer while charge more franchise fee to the h type retailer considering the government intervention reward penalty mechanism rpm is developed to stimulate the asymmetric information closed loop supply chain clsc we also analyze the impacts of rpm by comparing the cases whether or not rpm is implemented the comparison results show that the rpm can lower the wholesale price and retail price meanwhile raise buy back price and collection quantity finally several numerical studies are conducted for more managerial insights

extended producer responsibility instruments and innovation in eco design an exploration through a simulation model abstract this paper presents an agent based simulation model that models both economical and physical relations between firms recyclers and consumers this framework allows an investigation into the connection between physical environmental variables waste flows virgin material flows and economic decisions of agents in the product chain i e firms innovation strategies consumers choices and development of recycling activities the paper highlights the value of using agent based modeling as an operational tool to investigate the effect of waste prevention policy on economic and technological decisions of agents we focus on three types of extended producer responsibility epr instruments which are recycling fees tax subsidy and norms the simulation results show that the impact of each instrument depends on the policy design in particular on the level of stringency and on the reward system which is implemented we show that only tax subsidy systems and stringent norms can lead to radical innovations and to significant changes in product designs in the case of tax subsidy the impact relies more on an innovation effect while in the case of norm it mainly relies on a selection effect

environmental regulation of households an empirical review of economic and psychological factors abstract the literature on sustainable consumption and environmental regulation of household behavior is dominated by conceptual and normative approaches as a result many suggestions lack a firm empirical basis to overcome this deficiency econometric studies in three areas of environmentally relevant activities of households are reviewed residential use of energy generation of solid waste and recycling and residential use of water next to price and income elasticities attention is devoted to individual socio economic features and psychological factors such as attitudes knowledge perceptions and values potential psychological determinants and related insights are further examined by discussing a range of representative and illustrative statistical psychological studies of environmental behavior one important general finding is that there are very few empirical studies that systematically combine socio economic and psychological determinants a range of insights for environmental policy is derived and research recommendations are offered

an equilibrium model of the supply chain network under multi attribute behaviors analysis abstract this paper studies a supply chain network scn equilibrium model considering decision makers multi attribute behaviors from the perspective of behavioral finance in this paper an equilibrium model of an uncertain snc is constructed in which retailers choose their decisions according to their risk averse behavior loss averse behavior and regret averse behavior by using different weights to represent retailers attitudes to these three behaviors the retailers multi attribute utility functions are developed the equilibrium conditions of the manufacturers the retailers together with the network are established by the finite dimensional variational inequality formulation three numerical examples are solved in the first numerical example we illustrate the effect of each of these three behaviors on the equilibrium decisions the profits and the utilities of the decision makers in the other two numerical examples we explore the effects of changes in attitudes to these three behaviors on the equilibrium decisions profits and utilities of the decision makers the numerical results show that the equilibrium decisions are affected by each of these three behaviors very much moreover they are sensitive to the changes in attitudes to these behaviors

the effect of ethical orientation and professional commitment on earnings management behavior the purpose of this study is twofold the first objective is to examine the impact of an individual s ethical ideology and level of professional commitment on the earnings management decision the second objective is to observe whether the presence of a personal benefit affects an individual s ethical orientation or professional commitment within the context of an opportunity to manage earnings using a sample of 375 undergraduate business majors our results suggest a significant relationship between an individual s ethical orientation and decision making further participants with higher levels of professional commitment seem to be less likely to engage in earnings management behavior and less likely to behave opportunistically these results have the potential to add to our understanding of certain behaviors in entry level personnel and should be of interest to managers practitioners academicians and researchers

creative destruction and destructive creations environmental ethics and planned obsolescence three decades ago planned obsolescence was a widely discussed ethical issue in marketing classrooms planned obsolescence is topical again today because an increasing emphasis on continuous product development promotes shorter durables replacement and disposal cycles with troublesome environmental consequences this paper offers explanations of why product obsolescence is practiced and why it works it then examines the ethical responsibilities of product developers and corporate strategists and their differing responses to this problem pro environment product design and marketing practices and innovative government policies may alleviate the problem over time however given the current lack of understanding about consumer replacement and disposal behavior it is questionable as to whether these practices and policies will be sufficiently informed to be effective thus marketing scholars have a significant opportunity to contribute to sustainable durables product development

the influence of culture on budget control practices in the usa and japan an empirical study this article reports the results of a study that hypothesized the influence of culture on six aspects of budget control practices in the united states and japan data were collected through questionnaires from 70 manufacturing companies in the united states and 149 such companies in japan results of data analyses indicate that the individualism collectivism dimension would seem to explain why the u s companies compared to the japanese companies tend to use communication and coordination more extensively build budget slack to a greater extent and use long term performance evaluations to a lesser extent the implications of the results for further research and practice are discussed

product servicing for lifespan extension and sustainable consumption an optimization approach abstract sustainable consumption has been defined as the consumption of goods and services that meet basic needs and quality of life without jeopardizing the needs of future generations oecd 2002 lifespan extension of durable products underpins sustainable consumption this paper describes a novel approach to extend product lifespans by using product servicing that conceptualizes the interactions of a producer a policy maker and multiple consumer segments having different price demand relationships we propose a multi period mathematical optimization model that maximizes the producer s profit while optimizing the prices of different servicing options production quantities and inventory levels a computational study elicits several insights about how the optimal production or alternatively consumption quantities are affected by the introduction of product servicing and the effects of various product characteristics and government incentive or penalty levels on producer s profitability and on product servicing decisions we conclude that quantitative optimization models are useful for evaluating the impacts of different regulatory policies assessing the benefits of offering product servicing options and investing in design for durability and serviceability

monetary policy when potential output is uncertain understanding the growth gamble of the 1990s abstract t he fed kept interest rates low and essentially unchanged during the late 1990s despite a booming economy and record low unemployment these interest rates were accommodative by historical standards nonetheless inflation remained low how did the fed succeed in sustaining rapid economic growth without fueling inflation and inflationary expectations in retrospect it is evident that the productive capacity of the economy increased yet as events unfolded there was uncertainty about the expansion of the capacity of the economy and therefore about the sustainability of the fed s policy this paper provides an explanation for the success of the fed in accommodating growth with stable inflation in the late 1990s it shows that if the central bank is committed to reverse policy errors it makes because of unwarranted optimism inflation can remain in check even if the central bank keeps interest rates low because of this optimism in particular a price level target which is a simple way to model a commitment to offset errors can serve to anchor inflation even if the public does not share the central bank s optimism about shifts in potential output the paper shows that price level targeting is superior to inflation targeting in a wide range of situations the paper also provides econometric evidence that in contrast to earlier periods the fed has recently put substantial weight on the price level in setting interest rates moreover it shows that cpi announcement surprises lead to reversion in the price level finally it provides textual evidence that alan greenspan puts relatively more weight on the price level than inflation

efficient waste management policies and strategic behavior with open borders during the last decade waste management has been characterized by two main trends the growth of international trade of waste materials and the introduction of extended producer responsibility epr as a policy instrument in this paper a two country stylized model with imperfect competition in the recycling market is used to address two research questions first how do epr recycling targets interact with other policy instruments such as taxes on recycling residues and excise duties second how does strategic behavior of national policy makers influences the use of policy instruments the model demonstrates that a combination of epr with other instruments is needed to achieve the first best outcome when governments do not coordinate policies across borders strategic behavior may lead to a race to the bottom for taxes on recycling residues conversely strategic behavior may lead to a counter intuitive race to the top for excise duties and epr recycling targets it is shown that these instruments are not only used to stimulate waste prevention but also to extract rents from foreign recyclers

dynamic efficiency of extended producer responsibility instruments in a simulation model of industrial dynamics this article presents an original approach to the impact of extended producer responsibility instruments for waste prevention upon firms innovative strategies and market structure our analysis is based on a stylised framework of waste prevention developed by brouillat in this framework products are modelled as multi characteristic technologies whose evolution depends on firms innovation strategies and on the interactions with consumers and postconsumption activities recycling this stylised framework has been adapted to explore the impact of waste prevention instruments upon industrial dynamics and more particularly upon firms innovative strategies and upon the evolution of products characteristics and market structure we focus on two types of policy instruments recycling fees and norms for each instrument we will consider different policy designs in order to study their effects on industrial dynamics the main contribution of this article is to show how this type of simulation model can be used to explore the impact of waste prevention policy instruments on the technological evolution of products on innovation strategy and on the evolution of firms market shares the introduction of policy instruments in a simulation agent based model of industrial dynamics enables us to analyse more thoroughly how different policy designs can modify the dynamics of the system and more particularly how the incentives and the constraints linked to the policy instruments under consideration shape market selection copyright 2012 the author 2011 published by oxford university press on behalf of associazione icc all rights reserved oxford university press

can downstream waste disposal policies encourage upstream design for environment design for environment takes place when firms explicitly incorporate environmental issues in their product design and manufacturing decisions joseph fiksel 1996 to reduce waste associated with consumer products for example firms can reduce product weight including the amount of packaging that comes with a product and make products easier and less costly to recycle the latter can be accomplished by changing the type of material used in a product avoiding mixing of materials in a single product coding and labeling when different materials are used and designing for ease of disassembly u s congress office of technology assessment 1992 fiksel 1996 an important debate centers around the question of whether design for environment dfe needs to be explicitly targeted using policy instruments focused upstream on producers or whether downstream instruments send sufficient signals back upstream one important downstream instrument is a disposal fee i e charging households a price per pound per bag or per can for their trash many observers feel that downstream instruments do not send appropriate signals back upstream some economists and others have suggested on the other hand that disposal fees can in theory send signals upstream to producers karen palmer and walls 1998 we find that disposal fees provide incentives for efficient dfe only when there is a fully functioning recycling market i e only when recyclers pay households a price for each of their recyclable items and that price varies with the degree of product recyclability in the real world transactions costs of paying households for each individual item recycled would be prohibitively high in a more realistic setting in which households may place some items in a recycling bin but are not paid for doing so a disposal fee by itself will not yield a social optimum it encourages households to place items in the bin but all items allowed in the bin are of equal value to the household i e there is no reason to prefer an easily recyclable aluminum can to a difficult to recycle plastic milk jug this means that there is no signal to producers to make products more recyclable if the government can set product taxes that vary with product recyclability the social optimum can be restored but this option is not practicable 2 we argue that the infeasibility of i paying households for recycling and ii taxing products according to their recyclability means that a first best outcome is no longer attainable instead we set up a constrained second best optimum and solve for policy instruments that achieve this outcome we find that a disposal school of economics and finance victoria university of wellington wellington new zealand walls is also a university fellow with resources for the future washington dc the helpful comments of karen palmer don fullerton and hilary sigman are greatlv appreciated 1 manufacturer take back requirements such as germany s well known packaging take back law were developed at least in part as a way to encourage dfe see www oecd org env epr index htm for updates from a series of oecd workshops held in 1997 1999 on the broader topic of extended producer responsibility in practice individual german producers do not actually take back their own products at end of life they have formed a consortium that arranges to collect members waste from households marked with a green dot and recycle it we do not address take back mandates in this paper 2 in calcott and walls 1999 we derive these taxes don fullerton and wenbo wu 1998 show that a direct subsidy to recyclability combined with other instruments can yield a social optimum this subsidy depends on production function parameters thus if firms differ the subsidy would vary across firms more i mportantly observing and measuring recyclability to determine subsidy payments would be virtually impossible

competitive advantage through take back of used products abstract motivated by a recent antitrust ruling against hill rom one of the two dominant american suppliers of hospital beds we develop a stylized model to investigate the consequences of used product take back on firms industry and customers our findings suggest that by taking back and reselling refurbished products a manufacturer can increase both profit margins and sales to the detriment of a non interfering competitor in our model customers are always better off under product take back but it depends on the degree of competition whether firms use the benefits of take back primarily to increase their margins or to pass them on to the customers by lowering their prices the first firm to offer take back in some cases can deter its competitors from following this profitable strategy especially if it has an existing advantage in terms of lower production cost or higher market share contrary to the claim of hill rom s competitor we find a legitimate business justification for hill rom s reduction of new product prices

assessing the economic cost of greenhouse induced sea level rise methods and application in support of a national survey the potential cost of sea level rise has dominated many of the recent estimates of the economic damage that greenhouse warming might inflict on the united states over the course of the next century the cost of coastal protection and abandonment accounted for more than 80 of the early nordhaus estimate of likely damages part of a review of the then existing evidence which suggested that an effective doubling of atmospheric carbon concentrations might cost 0 26 of annual gdp the proportion of total cost attributed to sea level rise was a much smaller 11 in cline but the sea level rise costs that he quoted were among the most broadly accepted of his longer list of damages the relative importance of sea level rise in assessing the potential cost of greenhouse warming and thus in evaluating the potential benefit of any mitigating strategy has brought the original damage estimates under closer scrutiny a series of integrated assessments of aggregate damages has begun each has noted that the titus estimates were based on the assumptions that all developed property would be protected and that all undeveloped property including wetlands would be abandoned these assumptions were supported by comparisons of the economic vulnerability estimatesmore produced by yohe and protection cost estimates produced by weggel but they are clearly too simplistic some of each type of property will be abandoned though in which case the true future economic cost of sacrificed property must also be added to the damage calculus across an equally diverse collection of coastal sites moreover the decision of when whether and for how long to protect any piece of property will involve accurately weighing the tradeoff between the cost of its protection and the economic cost of its abandonment a balancing calculation which must be conducted on a site by site basis the key is to consider the world as it is likely to be and not necessarily as it is now 26 refs 1 fig 7 tabs less

pricing and quality decisions and financial incentives for sustainable product design with recycled material content under price leadership abstract design for recycling has been promoted by companies and governments around the world as one of the most important practices for achieving sustainability the success or failure of such a practice however depends heavily on the financial incentives for firms to design products with more recycled or recyclable material contents an interesting phenomenon that can be observed in many markets with products made predominately from either virgin or recycled materials is the existence of price leadership in this paper we utilize an interdisciplinary approach with both theoretical and empirical analyses to study the pricing and design decisions for products with virgin and recycled material contents in a duopoly market consisting of both the environmentally conscious green and non environmentally conscious brown consumers under price leadership our analytical results show that the brown segment s efficient quality provides an anchor product position for the price leader regardless of whether the price leader is a brown or green firm the price follower s financial incentive for becoming a green or brown firm will then lead to different cases of price leadership with very different environmental consequences specifically the arrangement where the brown and green firms are the price leader and follower respectively leads to more environmentally friendly design decisions than those under the other arrangement where the duopolists switch their pricing roles in addition we conduct an empirical analysis to explore the specific types of price leadership in the markets of aluminum cardboards and pet based on the equilibrium pricing and quality decisions we analyze the financial incentives for the more environmentally friendly case of price leadership to be realized and derive important insights to formulating strategies and policies to implement the practice of design for recycling from the interdisciplinary perspective

the two part instrument in a second best world abstract standard pigovian tax theory has been extended in two directions first many polluting activities are difficult to tax because they are not market transactions and so recent papers have shown that the same effects can be achieved by use of a two part instrument 2pi a tax on output or income and a subsidy for clean alternatives to pollution it is a generalization of a deposit refund system drs second a different literature concerns the second best pollution tax in the presence of other tax distortions here we combine the two extensions by looking at the second best 2pi when government needs revenue is the deposit larger and the rebate smaller we find explicit solutions for each tax and subsidy in a general equilibrium model with other tax distortions and we compare these to the rates in a first best model the tax subsidy combination is explained in terms of a tax effect an environmental effect and a revenue effect the model allows for flexible interpretation to show various applications of the 2pi we also discuss important caveats

does garbage pricing increase the immoral disposal of household waste abstractsome empirical studies have attempted to clarify the mechanism of illegal dumping by examining the degree to which per bag pricing plays a role however previous research on the behaviour of avoiding paying a charge for waste collection has tended to neglect so called immoral disposal which is less risky than illegal dumping because there is no legal penalty in this study we define immoral disposal as the dumping of waste in a manner that is immoral but not illegal to detect the existence of immoral disposal we apply a spatial econometric approach namely an extended panel spatial durbin model to identify the actual spillover effect of garbage pricing in neighbouring municipalities on immoral disposal from the total waste a major finding of this study is that immoral disposal exists in unit based pricing two tiered pricing and fixed pricing

feed in subsidies taxation and inefficient entry we study energy markets with dirty production and lumpy entry costs of clean production renewables for intermediate entry costs markets yield inefficient production and inefficient entry a mix of three popular regulatory instruments polluter taxation feed in subsidies for renewables and consumption taxation cannot correct these market failures for larger entry costs the instruments are imperfect because they affect marginal incentives whereas entry is a lumpy fixed cost problem whenever the first best is implementable feed in subsidies and consumption taxes are redundant the second best requires feed in subsidies or consumption taxes in addition to a pollution tax and overshoots first best levels given production levels the instruments do not affect the regulator s budget

the assessment the new economy the remarkable economic success of the united states in the 1990s led many observers to talk about a new economy this paper provides an overview of the main issues including faster productivity growth the stability of inflation despite very low unemployment the reduction in output volatility the role of monetary policy and the boom in the stock market the paper also considers whether or not the acceleration in productivity growth can be sustained and the possible implications for the rest of the world copyright 2002 oxford university press

smoothing income in anticipation of future earnings abstract recent theory argues that concern about job security creates an incentive for managers to smooth earnings in consideration of both current and future relative performance we find support for this theory our evidence suggests that when current earnings are poor and expected future earnings are good managers borrow earnings from the future for use in the current period conversely when current earnings are good and expected future earnings are poor managers save current earnings for possible use in the future however sensitivity analysis indicates that we cannot rule out selection bias as a potential alternative explanation for our findings

optimal policies for solid waste disposal taxes subsidies and standards abstract pricing trash collection and disposal services can be politically unpopular and may lead to increased illegal disposal of trash several studies have shown that deposit refund systems can act like disposal charges without the illegal disposal problem and thus can generate an optimal amount of solid waste disposal we assess the efficiency implications of an alternative policy currently in use in some states in the u s and considered at the federal level recycled content standards these are requirements that a certain fraction of total material use in production be comprised of secondary materials we find that such standards by themselves cannot generate the optimal amount of disposal but must be combined with additional taxes on both the final product and other inputs to production moreover the information requirements for setting the optimal standards and accompanying taxes are high the deposit refund approach would be preferred in most cases

reconsideration of an advance disposal fee policy for end of life durable goods abstract this paper analyzes the optimal waste disposal policy for durable goods the existing literature does not differentiate between durable and non durable goods and concludes that the social optimum can be attained by either a disposal fee df policy or an advance disposal fee adf policy in an economy without transaction costs this study shows however that in such an economy the first best policy is not an adf policy but a df policy adoption of an adf policy results in excessive consumption and disposal compared to the social optimum in addition under an adf policy the lifetime of durable goods is shorter than the social optimum if we take transaction costs into account we must consider the second best policy an adf policy can be considered as second best in some situations since it has some transaction cost advantages over other policies an adf policy can be second best either if net disposal cost is relatively low or if repair cost is relatively high

an economic analysis of household waste management abstract this paper provides a comprehensive model of household waste management policy incorporating the possibility of waste reduction effort by the firm and the household and of illegal waste disposal by the household when household waste reduction effort is insignificant the first best optimum can be achieved using various combinations of environmental tax on the firm and waste collection charge on the household however when household waste reduction effort is significant the first best optimum is not achievable and explicit monitoring of illegal waste disposal is needed rendering a simple pigouvian tax sub optimal this paper solves for the second best optimal policy and provides some comparative statics of the optimal policy

attitudes toward financial control systems in the united states and japan recently researchers have begun to investigate issues of differences in the use of managerial accounting tools across differing national environments much of this research is of the case study approach documenting actual practices for a small group of firms or a distillation from numerous observations but using anecdotal evidence to support various conjectures
