the demand for post compulsory education in the uk and the effects of educational maintenance allowances in this paper the author develops a model of investment in postcompulsory schoolin g based on human capital theory the model is estimated using data on a sample of sixteen and seventeen year olds derived from the family expenditure survey the results reveal significant differences in the factors influencing enrollment in postcompulsory education between m ales and females mot notably household income is an important deter minant of educational participation for females but not for their ma le counterparts on the basis of these results the author assesses t he effects of the introduction of educational maintenance allowances on participation rates in the united kingdom

the labour market participation of northern ireland university students this paper seeks to examine what factors are associated with student labour force participation in northern ireland in both term time and vacation making use of quarterly labour force survey data for the period march 1998 february 1999 the results suggest female students are more likely to work than male students mature students are less likely to work than non mature students roman catholic students are less likely to work than non roman catholic students students living at home are more likely to work than student living away from home and an increase in the actual or predicted wage increases the probability of labour force participation the author suggests that some of these results are due to the particular nature of the northern ireland socio economic situation while others are likely to be true for the rest of the united kingdom

existence of free entry equilibrium in aggregative games with asymmetric agents in this paper we examine a free entry aggregative game where agents can be asymmetric we show the existence of a pure strategy subgame perfect equilibrium of this game the proof is a constructive one and therefore we provide a method to derive a subgame perfect equilibrium within a reasonable time

water markets and freshwater ecosystem services policy reform and implementation in the columbia and murray darling basins abstract water markets have featured prominently in the reallocation of water rights to restore freshwater ecosystem health incentive based water rights acquisition and transactions have emerged as a market oriented policy approach to reallocate water resources from existing uses to enhance the provision regulation and sustainability of freshwater ecosystem services this paper develops a conceptual framework to examine factors enabling and constraining successful policy reform and implementation in market based environmental water allocation this analysis distills and extends the findings and lessons of a september 2007 workshop in brisbane australia on environmental water transactions two case studies were selected in water stressed basins the columbia u s a and murray darling australia basins where transactional approaches to environmental water allocation first emerged the case studies draw upon practitioner perspectives and previous policy and economic analysis in two regions where shared political economic and physical conditions lend a strong analytical basis for comparison a common set of policy and regulatory reforms has occurred in both cases albeit in different forms and via distinct paths to develop three enabling conditions 1 establishment of rights to and limits on freshwater extraction and alteration 2 recognition of the environment as a legitimate water use and 3 authority to transfer existing water rights to an environmental purpose however these elements of policy reform are necessary but not sufficient for effective implementation a second set of driving forces barriers and adaptations explains the ability to achieve larger scale ecological outcomes these conditions include the physical social and economic factors driving demand for environmental water allocation administrative procedures organizational development and institutional capacity to effect transfers and adaptive mechanisms to overcome legal cultural economic and environmental barriers the case study analysis suggests that environmental water transactions can play an important role in establishing environmental water allocations although water markets require ongoing institutional capacity and adaptive governance the conceptual framework and empirical lessons generated through this cross case comparison provide the basis for an expanded research agenda to evaluate the design and performance of market oriented reforms as implementation experience accrues and new programs emerge in diverse ecological and political economic settings

staying on in full time education the educational participation rate of 16 year olds this paper presents a time series analysis of the socioeconomic factors influencing the propensity of sixteen year olds to stay on in full time education in england and wales the econometric methodology employed relies on cointegration and general to specific techniques the results suggest that the main factors influencing staying on are the rate of return to education changing social class structure unemployment rates and the introduction of special employment and training measures such as the youth training scheme copyright 1991 by the london school of economics and political science

unemployment and early school leaving theoretical predictions about the effect of unemployment on school leaving are ambiguous unemployment might affect the decision to leave school in a number of different ways i current youth unemployment a higher probability of current unemployment for those who choose to leave school would tend to discourage early school leaving first by reducing the expected gains from job search a discouraged worker effect and second by reducing the opportunity cost of additional education ii expected future unemployment the theoretical predictions here are less clear cut an increase in the probability of future unemployment that affected both those with and without additional education would tend to reduce the rate of return to education and hence education demand on the other hand those with more education may be less affected by rises in unemployment and this may encourage further schooling these two opposing effects have been formalised as a shift and a tilt in the unemployment probability schooling relationship kodde i988 fig i suggests that in the united kingdom both effects could have accompanied the transition from the late 1970s to the i98o the full effects of uncertainty on education investment in a two period model depend on the correlation between the uncertainty in the two periods levhari and weiss 1974 how current unemployment rates are used to form expectations of future unemployment is clearly an important issue here also some individuals may be able to undertake job search before committing themselves to leave school and whilst affected by the risk of future unemployment may be comparatively unaffected by the risk of current unemployment iii effects ofparental unemployment parents unemployment in general reduces family income their children s educational demand may fall as a consequence for three reasons first the consumption demand for education will be lower second a reduction in the first period income reduces the investment demand for education assuming decreasing absolute risk aversion kodde i 988

will markets direct investments under the kyoto protocol lessons from the activities implemented jointly pilots under the kyoto protocol countries can meet treaty obligations by investing in projects that reduce or sequester greenhouse gases elsewhere prior to ratification treaty participants agreed to launch country based pilot projects referred to collectively as activities implemented jointly aij to test novel aspects of the project related provisions relying on a ten year history of projects we investigate the determinants of aij investment our findings suggest that review agency preferences related to national political objectives and possibly deeper cultural ties influenced project selection and limited the number of aij projects bilateral ties also appear to have affected investment decisions directly possibly because of related transaction costs the results suggest an investment process different from the assumptions that underlie well known estimates of cost savings related to the protocol s flexibility mechanisms we conclude that if approaches developed under the aij programs to approve projects are retained the scale of investment under kyoto s flexibility provisions and their cost savings will be less than what is generally anticipated and the pattern of investment less driven by abatement costs

managing online auctions current business and research issues the internet s computational power and flexibility have made auctions a widespread and integral part of both consumer and business markets though online auctions are a multi billion dollar annual activity with a growing variety of sophisticated trading mechanisms scientific research on them is at an early stage this paper analyzes the current state of management science research on online auctions it develops a broad research agenda for issues such as the behavior of online auction participants the optimal design of online auctions the integration of auctions into the ongoing operation of firms and the use of the data generated by online auctions to inform future trading mechanisms these research areas will draw from applied and theoretical work spanning management science economics and information systems

matching users rights to available groundwater abstract the amount of available groundwater in a catchment changes quickly and the amount of water that users can take sustainably depends on where and when it is taken however rights to water tend to be fixed and obtaining rights to water incurs high transaction costs as a result water catchments are over allocated worldwide in this paper i show how a catchment manager could match users rights to the available water in near real time despite uncertain future inflows while making effective use of all available hydrological data the solution uses the framework of a smart market a smart market is a periodic auction cleared with the help of an optimization model in addition to market clearing this model allows a convenient means to adjust initial rights and the auction revenue reflects the available water relative to users rights when the auction is revenue neutral the catchment may be viewed as allocated perfectly i suggest several ways in which a catchment manager can find this revenue neutral allocation assuming the manager has authority to adjust initial rights

poverty food security nexus evidence from a survey of urban slum dwellers in kolkata we explore the poverty food security nexus using an experience based indicator of food security constructed using a cross section sample of slum households in kolkata within the framework of a simultaneous ordered probit model we find a poor household is also likely to be food insecure additionally education gender and household composition are major drivers of food insecurity among low income urban households with the policy implication that anti poverty policies should be successful in eliminating household food insecurity however they need to be complemented with human capital investment and gender empowerment to be most effective

water markets design and evidence from experimental economics market mechanisms are gaining increasing acceptance all over the world as a way of making more efficient use of scarce water resources designing regulatory frameworks that ensure both inter and intra temporal efficient allocations is a daunting task especially if supply is stochastic and there is ample storage capacity in addition to defining tradable rights specific provisions must regulate the use of reservoirs commonly water statutes include provisions that establish asymmetries regarding the allocation of water and market restrictions that ban water trading across different users in this article we use data collected in a laboratory to test two specific market regulations included in the 1999 water reform in spain first junior right holders are not allowed to buy water from senior users second the law does not explicitly define water rights over units left in reservoirs for the following season results suggest that trading restrictions among water right holders lead to welfare losses for senior users it is shown that removing this restriction would increase senior right holders benefits without reducing those of junior users results show that defining water rights over saved units across periods would increase the average stock levels of reservoirs and reduce market price instability the lessons learned from the spanish experience are applicable to settings characterized by unstable natural water supply and the availability of large storage facilities

modelling the transition from school and the demand for training in the united kingdom this paper analyses the choices made by school leavers and the demand for training in the youth labour market using a large cross section database on all school leavers in lancashire in 1991 we model using a multinomial logit their first destination six months after the end of compulsory schooling we model six choices outcomes non vocational continuing education vocational continuing education youth training employment with on the job training employment with general skills training and unemployment our results show that the first destination from school is affected by a range of individual school and local labour market variables in addition to academic ability we report three effects that are not well known a young person is more likely to leave school the bigger the school the lower its academic performance and the lower his or her expected lifetime earnings our results might be interpreted as evidence of a segmented youth labour market it is also inappropriate to model the decision to stay on in continuing education as a simple binary choice

valuing options in water markets a laboratory investigation risk and reliability dominate water supply discussions in the arid western united states due to increasing demand and finite weather dependent supply water markets have evolved in this region so agencies could meet this growing demand in a few instances water agencies turned to contractual mechanisms such as options to manage supply as demand continues to grow option markets and other novel approaches to allocating water may become increasingly popular we utilize experimental economics to analyze the effect of annual options on water markets in the absence of sufficient real world data for conventional econometric analysis we find gains from trade are higher when options can be traded additionally gains are more evenly distributed particularly with a dominant buyer and many sellers findings suggest option markets may be a viable choice as policymakers prepare for future droughts

a simple auction mechanism for the optimal allocation of the commons efficient regulation of the commons requires information about the regulated firms that is rarely available to regulators e g cost of pollution abatement this paper proposes a simple mechanism that implements the first best for any number of firms a uniform price sealed bid auction of an endogenous number of transferable licenses with a fraction of the auction revenues given back to firms paybacks which rapidly decrease with the number of firms are such that truth telling is a dominant strategy regardless of whether firms behave non cooperatively or collusively the mechanism also provides firms with incentives to invest in socially optimal r d jel d44 d62 d82 q28 regulatory authorities generally find that part of the information they need for implementing an efficient regulation is in the hands of those who are to be regulated regulating externalities such as access to common resources e g clean air water streams fisheries etc is a good example environmental regulators for example know little about firms pollution abatement costs so without communicating with firms they would be unable to establish the efficient level of pollution a number of mechanisms have been proposed for inducing firms to reveal their private information but for different reasons

the effectiveness of yts as a manpower policy using data from the 1985 and 1986 scottish people s surveys this paper attempts to measure the effectiveness of the youth training scheme by estimating the impact of youth training scheme participation on both the subsequent probability of employment and the subsequent earnings potential the youth training scheme is found to have a positive impact on the probability of employment after allowing for possible sample selection bias owing to participation being nonrandom there are indications that the youth training scheme may have a positive impact on subsequent wages but the estimates are so imprecise that it was not possible to draw any statistically significant conclusions about wage effects copyright 1990 by the london school of economics and political science

characterizing spanish labour pathways of young people with vocational lower secondary education school to work transition is no longer considered to take place at one point but it is seen as a sequential process with multiple stages that extend over a relatively long period in which individuals gradually settle down into the labour market this article constructs and examines the labour pathways followed by spanish young people who have completed vocational lower secondary education to do so we use the survey on educational training transition and labour integration a retrospective longitudinal dataset that contains monthly calendar information about the labour states in the 4 years after completing vocational education a wide range of states is covered part time employment full time employment unemployment and several situations of inactivity to examine young labour pathways we use sequence analysis an exploratory technique which allows us to obtain a measure of dissimilarity between sequences later a cluster analysis is applied that allow us to identify seven patterns of transition into

designing climate mitigation policy this us paper provides an exhaustive review of critical issues in the design of climate mitigation policy by pulling together key findings and controversies from diverse literatures on mitigation costs damage valuation policy instrument choice technological innovation and international climate policy the authors begin with the broadest issue of how high assessments suggest the near and medium term price on greenhouse gases would need to be both under cost effective stabilization of global climate and under net benefit maximization or pigouvian emissions pricing the remainder of the paper focuses on the appropriate scope of regulation issues in policy instrument choice complementary technology policy and international policy architectures

an international policy architecture for the post kyoto era in february 2005 the kyoto protocol to the united nations framework convention on climate change came into force but without participation by the united states its impacts on emissions of greenhouse gases including carbon dioxide co2 the primary anthropogenic driver of climate change will be trivial but scientific robert t watson 2001 and economic charles d kolstad and michael a toman 2001 analyses point to the need for a credible international approach because the kyoto protocol s ambitious targets apply only to the short term 2008 2012 and only to industrialized nations the agreement will impose relatively high costs and generate only modest short term benefits while failing to provide a real solution joseph e aldy et al 2003 for these reasons most economists see the agreement as deeply flawed richard n cooper 1998 david g victor 2001 warwick j mckibbin and peter j wilcoxen 2002 although some see it as an acceptable first step axel michaelowa 2003 virtually all agree however that the protocol is not sufficient to the overall challenge we describe the basic features of a postkyoto international global climate agreement which addresses three crucial questions who when and how the respective elements are first a means to ensure that key nations industrialized and developing are involved second an emphasis on an extended time path of action employing a cost effective pattern over time and third inclusion of market based policy instruments i who expand participation to include all key countries

partial enclosure of the commons abstract we examine the efficiency distributional and environmental consequences of assigning spatial property rights to part of a spatially connected natural resource while the remainder is competed for by an open access fringe we refer to this as partial enclosure of the commons we obtain sharp analytical results regarding partial enclosure of the commons including 1 while second best it typically improves welfare relative to no property rights 2 all resource users can be made better off 3 positive rents arise in the open access area and 4 the resource maintains higher stocks under spatial heterogeneity we also characterize spatial regions that are ideal candidates for partial enclosure typically society should seek to enclose those patches with high environmental productivity and high self retention but whether high economic productivity promotes or relegates a patch may depend on one s objective

transaction costs and tradeable permits abstract tradeable permit systems are at the center of current interest and activity in market based reforms of environmental policy because these systems can offer significant advantages over conventional approaches to pollution control unfortunately claims made for their relative cost effectiveness have often been exaggerated transaction costs which may be significant in these markets reduce trading levels and increase abatement costs in some cases equilibrium permit allocations and hence aggregate control costs are sensitive to initial permit distributions providing an efficiency justification for politicians typical focus on initial allocations

tradeable carbon permit auctions how and why to auction not grandfather abstract an auction of carbon permits is the best way to achieve domestic carbon caps designed to limit global climate change to minimize administrative costs permits would be required at the level of oil refineries natural gas pipe lines natural gas liquid sellers and coal processing plants to maximize liquidity in secondary markets permits would be fully tradable and bankable the government would conduct quarterly auctions a standard ascending clock auction in which price is gradually raised until there is no excess demand would provide reliable price discovery an auction is preferred to grandfathering giving companies permits based on historical output or emissions because it allows reduced tax distortions provides more flexibility in distribution of costs provides greater incentives for innovation and reduces the need for politically contentious arguments over the allocation of rents

value added in further education and vocational training in northern ireland at the age of 16 many young people in the uk decide to leave school and enter vocational education or training either at a further education fe college or on a government training scheme in spite of the size and importance of this group the current debate about education and training standards has tended to focus more on how to improve schools largely neglecting the potential contribution to be made by the fe and vocational training sectors this study seeks to begin to redress this imbalance by examining the extent to which those young people leaving school and entering vocational education or training at 16 obtained further qualifications up to the age of 18 in particular there is an examination of whether the choice between fe and government training schemes at age 16 influences the subsequent success of young people in terms of gaining additional qualifications adopting an ordered probit approach to modelling qualifications levels the results contradict the somewhat pessimistic common pe

how do markets manage water resources an experiment we experimentally test how a private monopoly a duopoly and a public utility allocate water of differing qualities to households and farmers most of our results are in line with the theoretical predictions overexploitation of the resources is observed independently of the market structure stock depletion for the public utility is the fastest followed by the private duopoly and private monopoly on the positive aspects of centralized public management we find that the average quality to price ratio offered by the public monopoly is substantially higher than that offered by the private monopoly or duopoly

reconsidering the initial allocation of itqs the search for a pareto safe allocation between fishing and processing sectors advancement of rights based fishing is stymied by industry and congressional concern over distributional issues arising out of traditional itq design this paper examines the existence and policy feasibility of two alternative initial allocations intended to leave the two principal industry participants the fishers and processors no worse off while maximizing efficiency market structure is shown to be a critical consideration not only to avoid unintended wealth redistribution but also to achieve efficiency

bringing biophysical models into the economic laboratory an experimental analysis of sediment trading in australia abstract experimental economics has emerged and matured as a formal method for questioning and testing economic theory and assumptions concerning individual behavior more recently experimental methods have been used successfully in an economic laboratory to test alternative environmental policy options the data underpinning these experiments is often stylized or hypothetical in nature ecologists and experimental economists have much to gain by exploring ways to underpin economic experiments with data generated from biophysical models the study makes a contribution by demonstrating how underpinning experiments with regionally modeled biophysical data may give insights which would not necessarily arise from stylized data in this study sediment data generated from an environmental management support system emss a software model of sediment runoff in catchments was used to populate the players decision space the study investigated the relative performance of four different instruments closed first and second price call tenders cap and trade and command and control regulation these market instruments will be compared with the aim of promoting riparian management and reducing total suspended solids exiting a catchment the study finds that the cost of meeting regulatory requirement of sediment reduction through command and control is less than either first or second price auction however cap and trade produced high levels of convergence and production which moved towards minimizing the cost of achieving the cap reduction level

environmental regulation a value theoretic and class based analysis following a value theoretic and class based approach it is argued in this paper that ecological problems are inseparably linked to the process of extracting surplus value in capitalism and owing to their adverse impacts instigate struggles over the appropriation of nature these struggles fought within and outside the state by competing agents shape environmental regulation in particular taxes permits command and control measures and subsidies affect prices profits and rents and have class and other social implications evidence of current environmental regulation shows that it takes places under the great influence of capitalist concerns

a two level dynamic game of carbon emission trading between russia china and annex b countries this paper proposes a computable dynamic game model of the strategic competition between russia and developing countries dcs mainly represented by china on the international market of emission permits created by the kyoto protocol the model uses a formulation of i a demand function for permits from annex b countries and ii marginal abatement costs mac in russia and china provided by two detailed models gemini e3 is a computable general equilibrium model that provides the data to estimate annex b demand for permits and macs in russia poles is a partial equilibrium model that is used to obtain mac curves for china the competitive scenario is compared with a monopoly situation where only russia is allowed to play strategically the impact of allowing dcs to intervene on the international emission trading market is thus assessed

fishing quota markets abstract in 1986 new zealand responded to the open access problem by establishing the world s largest individual transferable quota itq system using a 15 year panel dataset from new zealand that covers 33 species and more than 150 markets for fishing quotas we assess trends in market activity price dispersion and the fundamentals determining quota prices we find that market activity is sufficiently high in the economically important markets and that price dispersion has decreased we also find evidence of economically rational behavior through the relationship between quota lease and sale prices and fishing output and input prices ecological variability and market interest rates controlling for these factors our results show a greater increase in quota prices for fish stocks that faced significant reductions consistent with increased profitability due to rationalization overall this suggests that these markets are operating reasonably well implying that itqs can be effective instruments for efficient fisheries management

futures contracts in water leasing an experimental analysis using basin characteristics of the rio grande nm providing for increased water demands during periods of persistent drought and climatic variability may require water managers users and planners to think differently about how water resources are allocated a water marketing institution that allows water rights holders to reallocate water on a temporary basis could overcome these challenges with minimal conflict in this paper a water marketing institution that allows for the temporary reallocation of water rights in a spot and futures market is investigated the results provide insight into three key questions 1 how does trading impact the physical system 2 does the value of water differ by trading agents 3 how is economic welfare redistributed as a result of trading results of experimental treatments display minor impacts to the physical system that prices differ across the different type of trading agents and the addition of a futures market has the ability to decrease market prices while increasing economic welfare as a futures market allows users to hedge against future water uncertainty

spot water markets and risk in water supply water availability patterns in semiarid regions are typically extremely variable even in basins with a highly developed infrastructure users are subject to unreliable water supplies incurring substantial economic losses during periods of scarcity more flexible instruments such as voluntary exchanges of water among users can help users to reduce risk exposure this article looks at the effects of spot water markets on the economic risk caused by water availability variations our theoretical and empirical risk analyses are based on the random profits of water users profit probability density functions are formally and graphically characterized for both water sellers and buyers under several possible market outcomes we conclude from this analysis that where water supply is stochastic water markets unambiguously reduce both parties risk exposure the empirical study is conducted on an irrigation district in the guadalquivir valley southern spain where there is a high probability of periods of extreme water scarcity water demand functions for the district representative irrigators and a spatial equilibrium model are used to simulate market exchanges and equilibrium this programming model is combined with statistical simulation techniques we show that the profit probability distribution of a representative irrigator is modified if water exchanges are authorized leading to risk reductions results also indicate that if the market were extended to several districts and users that are subject to varying hydrological risk exposure extremely low profit events would be less likely to occur in sum we show that exchanging water in annual spot markets can reduce farmers economic vulnerability caused by water supply variability across irrigation seasons these results support the water policy reform carried out in spain in 1999 to allow for voluntary water exchanges among right holders

how vulnerable is the emissions market to transaction costs an abms approach abstract the impact of transaction costs on the early emissions trading market is examined by applying an agent based model and simulation abms approach for a realistic model set up bounded rationality stochastic characteristics and learning by doing are considered in our search processes marginal abatement cost parameters are obtained from yoo et al 2010 which is an experimental study on the emissions trading in the korean power sector sensitivity analyses are performed on market performance indices with regard to transaction cost parameters which represent scales and the learning elasticities of transaction costs a total of 960 simulations were run in this sensitivity analysis sensitivity analysis results consistently show that higher transaction costs worsen market performance the most remarkable finding in these results is that welfare performance of all the transactions decreases by up to 50 as the scale parameters of transaction costs increase implying that welfare gain from introducing emissions trading disappears significantly however with learning curve effect welfare performance could be regained by up to 26 in sum although transaction costs significantly encroach upon trade gains at the early stage based on our simulation results the welfare loss by way of transaction costs is lessened as the knowledge of market participants progresses

sequestration offsets versus direct emission reductions consideration of environmental co effects abstract atmospheric greenhouse gas accumulation and consequential temperature increase can be remedied by emission reductions or agricultural carbon sequestration both options have direct and external environmental effects this paper examines the magnitudes of existing estimates of corresponding external co effects and how they could affect optimal combination of emission reductions and agricultural carbon sequestration we discuss whether government intervention in the form of taxation subsidization is justified for internalizing the externalities considering their relative magnitudes implementation costs and potential benefits that could be derived from such intervention we conclude that the existing estimates of external benefits from sequestration and emission reduction do not provide enough support for allocating resources to alter the market mix of carbon sequestration and direct emission reduction strategies

an evaluation of yts the youth training scheme yts is much the most significant public policy intervention in the uk training market since the 1964 industrial training act ita this paper presents an economic evaluation of yts we begin in part ii by outlining the history and mechanics of the scheme part iii describes the market failure or failures which yts addresses and part iv assesses how successful it has been in tackling these problems finally part v considers the scheme s future what further changes are needed to improve its effectiveness

contestability in the presence of an alternate market an experimental examination most earlier experimental tests ofthe contestable market hypothesis assume a zero opportunity cost of entry this design feature makes interpretation of results in terms of entry behavior problematic the experimental study that i report tests contestability with the addition of an alternate market that yields a positive profit with certainty this safe haven operationalizes a positive opportunity cost of entry hit and run entry is observed in the experiments adjusted mean prices are not significantly different from the zero opportunity cost case two methodological questions are also examined in one treatment sellers price offers are allowed only in 0 25 increments the simplification of the sellers decision space makes collusive arrangements more probable secondly market outcomes using human subject buyers are compared with outcomes from experiments with computer simulated demand the disciplining effect of human subject buyers results in market prices that converge to competitive levels more quickly the theory of contestable markets as presented by william baumol in his 1981 address as outgoing president of the american economic association has received considerable attention since its introduction the thesis of contestability is that we can model a market that attains a competitive outcome without the large numbers price taking assumption in the perfectly contestable market envisioned by baumol and others we would observe the efficient competitive price in equilibrium even with few or only one active seller the threat of entry is the disciplining force that sustains the efficient price as an equilibrium previous experimental tests of the contestable market hypothesis for the natural monopoly case all include at least two active firms pricing in every period the laboratory outcomes of these markets are indistinguishable from the destructive competition that has historically concerned scholars sharkey 1982 one can assert that the competitive prices that result from these natural monopoly markets are due to cutthroat competition because that market is the only game in town the study of the contestable natural monopoly that i report allows subjects the option of earning a normal rate of return in an alternate market thus there is at least the possibility that we can observe a single active seller choosing the efficient price

transitional politics emerging incentive based instruments in environmental regulation abstract this paper proposes a positive theory of environmental instrument choice we study a democratic society that seeks to lower the level of pollution from industrial sources to a pre specified target the target can be implemented by one of three instruments s uniform emission standards p tradeable permits and t emission taxes the conflict of interest between special interests representing polluters and the electorate is resolved by an elected politician we characterize when each of the three policy instruments is chosen in political equilibrium and show that the transition observed in many countries from s to either p or t can be understood as a natural consequence of increasingly ambitious environmental targets

careers guidance psychometric testing and unemployment amongst young people an empirical analysis for northern ireland psychometric tests continue to form an important part of careers guidance for young people of school leaving age throughout the uk in the existing literature there is little evidence about the impact of testing on subsequent labour market success this paper presents a quantitative analysis of the effect of testing in northern ireland on young people s subsequent experiences of unemployment and long term unemployment between the ages of 16 and 18 on account of the sample selection problem standard single equation estimates of the effects of testing are likely to give biased results and so the bivariate probit model is used in the estimation the results suggest that although testing is not having an adverse impact it is not having a statistically significant positive effect this may be attributable to some aspects of test administration in northern ireland which in many cases seems to fall short of recommended guidelines
