the private wage sector in cote d ivoire homogeneity or heterogeneity one dominant feature of economic development is change in the structure of the economy some sectors expand while others shrink in response to changes in output markets considerable adjustments must take place in factor markets as well development will therefore proceed more speedily when barriers in the factor markets are minimal whether or not barriers in the labor market exist macroeconomic discussions of labor markets usually assume uninhibited flows between sectors 13 similarly a large literature on earnings of wage workers has treated the wage sector as a homogeneous part of the labor market yet if the wage sector is heterogeneous model estimates have no empirical meaning and policy recommendations have no foundation

individual taxpayer response to tax cuts 1982 1984 with implications for the revenue maximizing tax rate abstract this paper measures the response of taxpayers to the u s personal rate reductions from 1982 to 1984 a baseline income distribution is created to describe what level and distribution could be expected in the absence of tax changes comparison of this baseline with actual tax return data shows that at least one sixth and probably one quarter of the revenue ascribable to the rate reductions was recouped by changes in taxpayer behavior the data also show that federal income tax revenue would have been maximized at a tax rate of about 35 percent and total income tax revenue maximized at a total tax rate of about 40 percent

cross hedging and forward contract pricing of electricity we consider the problem of an electric power marketer offering a fixed price forward contract to provide electricity that it purchases from a potentially volatile and unpredictable fledgling spot energy market one option for the risk averse marketer who wants to hedge against the spot price volatility is to engage in cross hedging to reduce the contract s profit variance and to determine the forward contract price as a risk adjusted price the sum of a baseline price and a risk premium we show how the marketer can estimate the spot price relationship between two wholesale energy markets for the purpose of cross hedging as well as the optimal hedge and the forward contract s baseline price and risk premium

support systems for the diffusion of renewable energy technologies an investor perspective concern over climate change impacts and the projected depletion of fossil fuels has urged more governments to adopt policies that stimulate the diffusion of renewable energy technologies ret with an increasingly diverse suite of support instruments the question emerges as to which instruments or combinations are able to achieve faster more substantial diffusion results although various support instruments were extensively addressed in policy studies there is still no consensus this is partly because many policy studies take a policy maker approach in comparing support instruments leaving relationships between policy design and policy results as a black box this paper proposes an investor oriented perspective to analyze the diffusion potential of support systems for ret the main argument is that it is not the type of support instrument but rather its risk profitability characteristics that influence investor behavior and the rate of diffusion the two instruments most frequently discussed and compared are the feed in tariff and the quota model the analysis in this paper concludes that policy design is crucial while often feed in tariffs are applauded and quota system feared feed in tariffs may also bring about disappointing diffusion results when poorly designed while quota systems may be also conceived as attractive instruments for independent power producers

the importance of group coverage how tax policy shaped u s health insurance in 1954 the internal revenue service stipulated that employer contributions to the health insurance plans of their employees were to be excluded from employee taxable income today the tax subsidy is major feature of the u s health care market this paper examines the initial effects of the tax subsidy on the demand for health insurance using previously unexamined data from 1953 and 1958 results suggest that the tax subsidy increased the growth of group insurance particularly among union members and employed persons this is a critical effect because group insurance is not only less expensive than individual insurance but it is also easier to obtain and households with access to group health insurance are far more likely to purchase health insurance coverage than those without similar access by increasing access to group insurance the tax subsidy fostered an increase in the purchase of group health insurance by people who may not have purchased individual coverage and generated institutional change as it cemented an employment based system of group health insurance in the united states this abstract was borrowed from another version of this item

the new electricity market of singapore regulatory framework market power and competition abstract this study examines whether the new electricity market of singapore nems is functioning at a workable level of competition the generation market of the nems appears highly concentrated by a four firm concentration ratio or the herfindahl hirschman index however other measures of market power present that the nems is working at close to a competitive market first there seems to be a number of effective competitors in the market second supply margin assessment and residual supply index support that the market is competitive though there are some possibilities in which the largest generator or a few large generators jointly could still have market power third the lerner index of the nems shows that the generation market is fairly competitive and the lerner index adjusted with an industry level price elasticity of demand implies that there has not been much exercise of market power finally vesting contracts a contractual obligation of a specified quantity of electricity supply to the market have appeared to be a strong and effective tool to mitigate market power in the nems the vesting contracts are considered the force behind the lowering in the average uniform singapore electricity price and the lerner index in 2004

market price behavior of wholesale electricity products texas abstract applying a regression based approach to a newly developed sample of over 60 000 hourly observations for 01 01 2011 12 30 2017 we answer the question what moves the day ahead market dam prices for energy and ancillary services as and the real time market rtm price for energy in the electric reliability council of texas ercot our answer comprises the following findings that capture the interdependence of ercot s energy and as products 1 the dam energy price increases with the day ahead forecasts of natural gas price system load and as requirements but declines with nuclear and wind generation s forecasts 2 the as prices increase with the dam energy price and the as procurement forecasts but decline with the as offer forecasts and 3 the rtm energy price increases with the dam energy price but diverges from the dam energy price due to forecasting errors related to the dam energy price s fundamental drivers these findings imply that texas can reduce the prices for day ahead energy day ahead as and real time energy via wind generation development and demand side management further texas can improve its electricity trading efficiency by improving ercot s forecast accuracy to narrow the rtm energy price s divergence from the dam energy price

sources of intra industry wage dispersion how much do employers matter observed human capital explains less than half of wage variation in bls industry wage surveys establishment based wage differentials controlling for occupation account for 20 70 percent of intra industry wage variation this corresponds to a standard deviation in wages of 14 percent of the mean almost as large as interindustry wage variation investigation suggests that establishment wage differentials are not random variations or returns to usual measures of human capital

efficiency and deregulation of the electricity market in singapore this study examines production efficiency of electricity generation in the new electricity market of singapore nems where deregulation is currently proceeding singapore is reliant on foreign direct investments and exports so competition from countries with lower costs such as china and india is exerting pressure on the government to reduce the costs of doing business here electricity cost is one of these deregulation is believed to be able to bring about lower electricity costs due to the various efficiency gains possible this study concerns itself mainly with production efficiency and attempts to calculate possible production efficiency gains by using linear programming model production efficiency gains are quantified by the base case scenario of continued regulation versus four counterfactual deregulation scenarios the results indicate that cost gains could be about eight per cent of current production cost and this is possibly a lower bound estimate however whether the purported efficiency gains are realized is to be seen as the deregulation proceeds

determinants of female administrative support personnel compensation at a large public university compared with research on faculty salaries and executive compensations very little is known about the earnings of administrative office support personnel this paper constructed and estimated the total compensation variant of a modified human capital earnings model using a 1989 90 fiscal year microdata sample consisting of about 300 all female office workers administrative secretaries regular secretaries and clerks at a large public university the total compensation consisting of wages plus actual dollar costs of five employer paid health life accident longevity sick leave vacation and pension benefit plans specification fitted the data reasonably well the pattern of estimated differential returns to specific human capital attributes within administrative support occupations tends to be significant and is consistent with the skill atrophy prediction of the human capital theory implications of the findings for secretarial productivity career choice decisions and opportunities for advancemen

us regionalism and rationality regionalism continues to be proffered as a policy prescription for us metropolitan ills while many urban scholars discuss the benefits of regional approaches to problem solving others question and sometimes dismiss the possibility of widespread comprehensive regionalism this latter group generally takes one of two perspectives first they argue that local autonomy and fragmentation prohibit regional collaboration secondly rational choice theorists claim jurisdiction centred economic interest spurs intraregional competition and impedes cooperation although both perspectives can be criticised as overdeterministic they appear to be supported by the limited number of examples of comprehensive metropolitan co operation in the us this article identifies a theoretical connection and empirical similarity between these views of impediments to regionalism the author argues that strategies suggested by rational based collective action theory apply to either the autonomy or competition argument however

managing electricity procurement cost and risk by a local distribution company abstract a local electricity distribution company ldc can satisfy some of its future electricity requirements through self generation and volatile spot markets and the remainder through fixed price forward contracts that will reduce its exposure to the inherent risk of spot price volatility a theoretical framework is developed for determining the forward contract purchase that minimizes the ldcs expected procurement cost subject to a cost exposure constraint the answers to the questions of what to buy and how to buy are illustrated using an example of a hypothetical ldc that is based on a municipal utility in florida it is shown that the ldcs procurement decision is consistent with least cost procurement subject to a cost exposure constraint and that an internet based multi round auction can produce competitive price quotes for its desired forward purchase

does california s co2 price affect wholesale electricity prices in the western u s a abstract using a sample of daily market data we quantify the effect of california s co 2 cap and trade program on the wholesale electricity prices of four interconnected market hubs in the western u s a north of path 15 np15 and south of path 15 sp15 in california mid columbia mid c in the pacific northwest and palo verde pv in the desert southwest a 1 metric ton increase in california s co 2 price is estimated to have increased the electricity prices by 0 41 mwh p value p value p value 0 0056 for mid c and 0 15 mwh p value 0 0925 for pv these estimates reflect a the np15 and sp15 sellers pricing behavior of fully including the co 2 price in their intra state transactions b the mid c price s 100 pass through of the co 2 price in the pacific northwest s hydro export to california and c the statutory obligation of paying the co 2 emissions cost by california s buyers of the electricity imported from the desert southwest the policy implication is that internalization of co 2 s externality in the western u s a requires a cap and trade program with a regional scope that encompasses all four hubs thereby remedying the california program s limited geographic coverage which introduces distortions in neighboring markets

compensating differentials and self selection an application to lawyers this paper models individual choice between two types of jobs as dependent on the difference in potential earnings and on preferences for nonpecuniary the model leads to simultaneous estimation of earnings and job choice functions in a manner that takes account of self selection of individuals into the sector of highest utility an application to lawyers choosing between private and public interest law casts doubt on the notion that public interest lawyers are accepting substantially lower earnings by virtue of their choice an impression derived from estimation of earnings functions without accounting for self selection the estimation technique also takes proper account of the choice based nature of the sample which appears to be important

employers provision of pensions and sick pay evidence from the 1990 workplace indistrial relations survey this paper examines the determinants of pension and sick pay provision using data on some 1100 private sector establishments with 25 or more employees it also compares the wages of employees eligible for a pension or for sick pay with the wages of those for whom no such provision was made using ordered probit techniques three levels of provision were examined with respect to each type of benefit no provision provision for white collar employees only and provision for all employees benefit provision was found to be associated with work place size and with the extent to which employment was white collar it was negatively associated with the level of part time working new establishments were slightly less likely to offer pensions than older ones but age had no impact on sick pay provision perhaps because it is less complex and costly than pension provision establishments which recognized trade unions were more likely to offer fringe benefits than those which did not however blue collar unions se

does health insurance reduce illness related worker absenteeism the objective of this article is to examine whether having health insurance reduces illness related absenteeism among older workers a nationally representative sample of 1780 workers in the united states aged 52 64 are drawn from the 2004 2006 health and retirement study hrs binary logistic regressions and censored tobit models are estimated for workers likelihood of missing work days due to illness and the number of illness related work days missed respectively while explicitly addressing the possibility of insurance selection effects the findings suggest that over a 12 month period older workers without health insurance are as likely as insured workers to miss work days due to illness and there are no differences in the number of days missed between insured and uninsured workers however there is strong evidence that poor baseline health onset of new diseases and longer hospitalization significantly increase an older worker s absenteeism at work these results suggest that having health ins

cost benefit analysis of reforming israel s electricity industry abstract in june 2003 the israeli government decided to reform the israeli electricity industry which is currently dominated by israel electric corporation iec a government owned vertically integrated electric utility the first step of the planned reform will be taken in 2006 when iec will be functionally separated into generation transmission local distribution and customer services immediately thereafter will be the second step which by 2012 will result in the deregulation and privatization of the wholesale generation and customer services transmission and distribution t and d services will remain regulated but will be available to all t and d users under mandatory open access this paper summarizes a cost benefit analysis of the government s reform plan relative to a regulated regime the government s plan even if carried out flawlessly may only yield a small net benefit however it entails a large increase in electricity producer profit and government tax receipt at the expense of electricity consumers a less than perfect transition to competition can easily wipe out the potential gain of the government plan market reform experience to date shows that electricity market reform can easily fail and the factors for success do not exist in israel since the outcome of a failing reform can be disastrous it will be imprudent to implement the government s plan in 2006 when the current electricity law expires hence we recommend performance based regulation for the period of 2006 2010 subject to an updated cost benefit analysis possible decentralization privatization and competition may follow

electricity procurement for large consumers based on information gap decision theory in the competitive electricity market consumers seek strategies to meet their electricity needs at minimum cost and risk this paper provides a technique based on information gap decision theory igdt to assess different procurement strategies for large consumers supply sources include bilateral contracts a limited self generating facility and the pool it is considered that the pool price is uncertain and its volatility around the estimated value is modeled using an igdt model the proposed method does not minimize the procurement cost but assesses the risk aversion or risk taking nature of some procurement strategies with regard to the minimum cost using this method the robustness of experiencing costs higher than the expected one is optimized and the related strategy is determined the proposed method deals with optimizing the opportunities to take advantage of low procurement costs or low pool prices a case study is used to illustrate the proposed technique

a note on the substitution between wage and non wage benefits in spot labour markets abstract recent empirical work suggests that spot labour market workers have a strong preference towards wages over fringe benefits this paper provides a theoretical framework based on this finding after a discussion of the utility function and equilibrium the paper proceeds to a comparative statics analysis an important result is that workers spend all extra compensation on wages only this is shown to be true in the case that wage benefits are taxed furthermore proportional taxes have no effect for workers choice between wage and non wage benefits

the elusive wage benefit trade off the case of employer provided health insurance this study shows that standard regressions estimated to measure a trade off between wages and health insurance are misspecified by insufficiently accounting for establishment and firm size an interactive size corrected specification is more likely to reveal a trade off furthermore because insurance decisions are typically made by firms and wages set by establishments the insurance constraint on establishments in multi establishment firms weakens the trade off we use model generated data to show that both factors contribute to the failure in previous research to identify a trade off and data from a cross section of northern californian establishments to test for a trade off in multi establishment and single establishment firms

interjurisdictional determinants of property assessment regressivity the previous literature on vertical equity in property assessment has focused on parcel level data within a single area and has produced mixed conclusions on whether the process is progressive or regressive this paper advances the discussion to identifying what differences between jurisdictions might account for the mix of findings using data from virginia cities and counties between 2001 and 2007 evidence is presented that indicates having tax maps available online appointed assessors and senior citizens all influence the level of regressivity observed between jurisdictions overall the results support the hypothesis that interjurisdictional differences are determinants of vertical inequity

the impact of wind generation on wholesale electricity prices in the hydro rich pacific northwest extant literature documents that wind generation can reduce wholesale electricity market prices by displacing conventional generation but how large is the wholesale price effect of wind generation in an electricity market dominated by hydroelectric generation we explore this question by analyzing the impact of wind generation on wholesale electricity prices in the pacific northwest region of the united states this hydro rich system tends to be energy limited rather than capacity constrained with its marginal generation during the hydro runoff season often a hydro unit instead of a natural gas fired unit we find that increased wind generation reduces wholesale market prices by a small but statistically significant amount while a hydro rich system can integrate wind generation at a lower cost than a thermal dominated region the direct economic benefits to end users from greater investment in wind power may be negligible

optimal executive perquisites abstract expenditures by executives on personal perquisites can be optimal for the board of directors using a principal agent model we present a numerical example where the principal can reduce the total cost of compensation for the agent by offering a lower expected bonus and a larger budget allocation from which the agent diverts some funds to perquisites this is optimal when the agent has sufficiently large diminishing marginal utility for perquisites

value of an option to purchase electric power the case of uncertain consumption abstract large manufacturers and corporations often purchase options on power to protect themselves against unanticipated price increases this paper analyzes the impact of uncertainty in power consumption by a corporation on the value of an option to purchase electric power because there is no economically viable method to store power these options are exercised to satisfy immediate consumption needs only the amount exercised may differ from the maximum amount contracted which in turn alters the payoffs that accrue to the option contract we apply a monte carlo methodology to show that consumption uncertainty may substantively lower the price of an option contract under different conditions

modeling and pricing of block flexible electricity contracts this paper presents a model for block flexible electricity contracts bfec and focuses on pricing the bfec based on the principle of no arbitrage energy is traded in blocks according to its time duration at different block prices which is called block trading the bfec requires the buyer or the seller to schedule its trading amount and the certain block of power at each time interval the block trading needs to divide the power into several blocks the prices of each power block are obtained from market clearing price by using the autoregressive model ar n as stochastic block price model an optimal scheduling strategy can be achieved by stochastic dynamic programming the price of bfec is determined by the variables and schedule of the bfec contracts with different choices of block are studied and the simulations illustrate the block flexible electricity contracts can improve power market efficiency

a new test for supplier inducement and application to the canadian market for dental care abstract the hypothesis that dentists do not induce demand for their services is tested using reduced form estimates of the price elasticity of demand if demand is autonomous shifts in supply for whatever reason should generate equivalent estimates provided access costs change proportionately with shifts in supply if demand inducement is present demand can appear to be very elastic or very inelastic depending on what is causing the shift in supply each of three applications of this test conducted in the context of jointly estimated fee and quantity equations using annual canadian data for 1956 1989 rejects the no inducement hypothesis

farming the tax code the impact of high marginal tax rates on agricultural tax shelters surprisingly little scholarly work has examined the practice of farming the tax code in which accounting losses on agricultural investments are used to shelter other income from taxation economic theory suggests that the amount of investment in agricultural tax shelters is positively related to the marginal tax rate this hypothesis is empirically investigated using a sample of federal individual income tax returns filed for 1983 both the probability of reporting a farm tax loss and the amount of farm losses are increased by a rise in the marginal tax rate especially among upper income taxpayers

tax preferences for fringe benefits and workers eligibility for employer health insurance abstract in this paper i estimate the effect of the tax preference for employer provided health insurance on the probability that an employee will be eligible for health insurance at work i instrument for marginal tax rates with state level state income tax rates and i control for unobservable state effects that could be correlated with the state income tax instrument by comparing the estimated tax effect on employer provided health insurance to the tax effect on sick leave a fringe benefit that does not enjoy any tax advantage the size of the tax effect on health insurance eligibility is positive as predicted and is both statistically and economically significant

consumer rationality and the status quo received microeconomic theory presumes rational consumers maximize utility over all commodity bundles recent analysis however suggests that a consumer s status quo may limit economic rationality bias consumer decisions and induce serious errors in survey based valuations of public and private goods using regression and choice theoretic frameworks we investigate the existence of status quo effects in the consumer valuation of a particular unpriced product the reliability of residential electrical service such valuations have become important in electric utility resource planning and rate making we find substantial status quo effects which must be addressed in welfare comparisons regarding electric service reliability

getting reforms done in inhospitable institutional environments untying a gordian knot in india s power distribution sector when grand institutional reforms based on idealized models are stalled by the poor institutional environments and difficult politics which often surround large infrastructure systems in developing countries partial reforms whose design and implementation take into account the different interests of the key stakeholders can provide valuable and immediate benefits while moving these systems from low towards higher level equilibria strategically negotiated experimentally partial and purposefully hybrid these reforms are based on careful stakeholder analysis and strategic coalition building that avoid rigid positions based on idealized models our findings are based on a study of power sector reforms in india where we performed a micro level and in depth analysis of a partial and innovative experiment which has allowed private sector participation in electricity distribution within a hostile institutional environment

a framework to evaluate security of supply in the electricity sector security of electricity supply soes has become a major concern for regulators and policymakers over the last decade however most work focusses either more generally on energy security or on a single fuel we develop a comprehensive but flexible framework to assess the soes for a single jurisdiction taking into the account the specificities of electricity this framework has two aims i provide a snapshot of the situation to understand current weaknesses and determine what actions are required ii capture the evolution over time to evaluate progress and identify potential problems before they materialise the framework based on an extensive literature review consists of twelve dimensions that are critical for soes we develop metrics that capture the state and evolution of each dimension this framework is intended to be a management information tool for all stakeholders aimed at organising data and structuring its analysis to enable monitoring the evolution of the soes while also functioning as an early warning system by flagging potential future problems

organization and functioning of liberalized electricity markets an overview of the dutch market abstract in this paper we examine the organization and the functioning of the dutch electricity market first we describe the organization of the dutch electricity supply chain and the role of the main market participants including the transmission system operator distribution system operators program responsible parties and metering companies we then describe the organization of financial trading and clearing mechanism of electricity through the organized futures exchange the european energy derivatives exchange and the spot market amsterdam power exchange which includes the day ahead market and intra day markets we also detail the functioning of the imbalance market and reserve capacity management in the netherlands through a set of numerical analysis we provide an exploratory analysis of the apx day ahead spot prices and the real time imbalance prices using electricity price data from 2002 to 2013 we observe the price spikes both in the day ahead and imbalance markets usually occur around 6 10 am and 5 7 pm we also observe that in the imbalance market system overages happen significantly more often than shortages pointing out that the market tends to buy more than what is demanded this could be explained by the risk attitude of the market participants in the imbalance market

people i know job search and social networks we assess the strength of information spillovers relating unemployment duration of workers displaced by firm closures to their former colleagues current employment status displaced specific networks are recovered from a 20 year panel of matched employer employee data spillovers are identified by comparing performances of codisplaced workers a one standard deviation increase in the network employment rate reduces unemployment duration by about 8 the effect is magnified if contacts recently searched for a job and if their current employer is spatially and technologically closer to the displaced worker stronger ties and lower competition for information favor reemployment several indirect tests exclude other interaction mechanisms

electricity retail contracting under risk aversion abstract risk has always been a dominant part of financial decision making in any industry recently models tools and computational techniques have been developed so that we can effectively incorporate risk in optimal decision policies the focus of this paper is on electricity markets where much of the inherent risk falls on the retail sector we introduce a three stage model of an electricity market where firms can choose to enter the retail market then enter into retail contracts and finally purchase electricity in a wholesale market to satisfy their contracts we explicitly assume that firms are risk averse in this model we demonstrate how the behaviour of firms change with risk aversion and use the example of an asset swap policy over a transmission network to demonstrate the importance of modeling risk aversion in determining policy outcomes

the role of pensions in the labor market a survey of the literature because employer sponsored group pension plans entail agreements between workers and their employers explicitly linking future payment and employment they offer an unusual window into long term employment relationships this review of recent research on pensions explores how pensions influence employee compensation retirement turnover and other matters central to the determination of labor s price and quantity over time the authors also outline some unanswered questions and difficult to reconcile findings because the pension promise involves an explicit and relatively well documented set of statements regarding future contingent payment and employment an examination of the design and operation of employersponsored group pension plans can yield important insights into the long term employment relationship specifically pension research illuminates some important labor market questions in two ways it offers insight into an important element of compensation in its own right and it furthers our understanding of labor markets in which long term

a real options evaluation model for the diffusion prospects of new renewable power generation technologies this study presents a policy planning model that integrates learning curve information on renewable power generation technologies into a dynamic programming formulation featuring real options analysis the model recursively evaluates a set of investment alternatives on a year by year basis thereby taking into account that the flexibility to delay an irreversible investment expenditure can profoundly affect the diffusion prospects of renewable power generation technologies price uncertainty is introduced through stochastic processes for the average wholesale price of electricity and for input fuel prices demand for electricity is assumed to be increasingly price sensitive as the electricity market deregulation proceeds reflecting new options of consumers to react to electricity price changes such as time of use pricing unbundled electricity services and choice of supplier the empirical analysis is based on data for the turkish electricity supply industry apart from general implications for policy making it provides some interesting insights about the impact of uncertainty and technical change on the diffusion of various emerging renewable energy technologies

a theoretical analysis of procurement auctions for tertiary control in germany as far as energy policy is concerned the design of the regulatory framework for energy transmission and distribution is a key issue consequently also the embodiment of balancing power markets drives mainly the effectiveness of political implications for the energy sector initially tertiary control in germany was solely offered by transmission system operators of the respective power control areas and their associated power plant the recast of the energy industry act of 2005 led in last consequence to a common procurement auction for the supply of tertiary control which starts on december 1 2006 admittedly the reform has fallen short of expectations so far first concerning the intensification of market entry of tertiary control providers as well as the desired decline of the price level hence this article examines the effects of the changeover on observable demand charges in order to identify attributes of the common procurement auction for tertiary control hampering market entry of providers giving stimuli to collusion and strategic behavior reducing intensity of competition and encouraging an upswing of prices we analyze the design under an auction theoretical approach and deduce empirically whether structural components of the auction design have to be touched up again

reforming israel s electricity sector abstract this paper analyzes the regulatory structure of the electricity sector in israel which is currently dominated by the government owned integrated utility israel electric corporation iec the current structure of a price cap with a mandatory rate reduction of 2 per year and a target return on equity roe of 6 5 is not sustainable because of iec s deteriorating financial health caused by the substantial investments it made to meet the 7 2 per year electricity demand growth in the past decade which has led to an exceptionally low realized roe of 3 4 for that period the investment trend will continue thanks to the 4 5 per year gdp growth projected for the next 10 20 years part of our proposed remedy is performance based regulation pbr implemented via a a price cap formula that will restore iec s financial health and offer iec downward pricing flexibility b changes in how iec compensates its workers and c a sliding scale plan that provides incentives for iec to become more efficient and to share risk with its customers we augment the pbr proposal by recommending changes in iec s tariffs and resource procurement procedures that aim to promote the development of a competitive power industry in the next 10 15 years

electricity market reform failures uk norway alberta and california an analysis of electricity market reforms already taken place in the uk norway alberta canada and california usa leads to our overall conclusion that the introduction of a competitive generation market of itself has failed to deliver reliable service at low and stable prices the market reform failures are attributed to market power abuse by few dominant sellers especially at times of transmission congestion poor market design that invites strategic bidding by suppliers the lack of customer response to price spikes capacity shortage caused by demand growth not matched by new capacity and thin trading of forward and futures contracts that are critical for price discovery and risk management the paper then explains why an electricity market reform can easily fail to deliver the promised gains of better service at lower and more stable prices the policy implication is that an electric market reform can be extremely risky and may lead to a disastrous outcome thus it is imprudent to implement such a reform in countries with limited sites for newgeneration and no indigenous fuels e g israel and hong kong these countries should therefore consider introducing performance based regulation that can immediately benefit electricity consumers in terms of lower prices more stable prices improved reliability more choices while encouraging the electric sector to pursue efficient operation and investment r 2003 elsevier science ltd all rights reserved

labor market effects of employer provided health insurance i introduction increasing health insurance coverage is arguably an important policy goal the congressional budget office 2003 estimates that in 1998 20 30 million americans had no health insurance for the entire year approximately 40 million were uninsured at a specific point in time in the year and nearly 60 million were without coverage some time during the year most individuals who have health insurance in the united states obtain it through their employer in 1999 65 8 of nonelderly americans had employer provided insurance also called group insurance or employer sponsored insurance either through their own employer or through the employer of another household member see gruber 2001 employer provided insurance plans generally have lower premiums and offer more benefits than individual insurance plans health insurance providers can offer cheaper and better plans to company employees for at least two reasons first the average administrative cost of such plans is lower than individual plans second employment based plans are typically subject to less adverse selection than individual plans particularly so for large employers furthermore the tax subsidy afforded employment based health insurance renders the effective consumer price substantially lower than the cost see pauly 1986 and gruber 2001 together these various factors give a strong incentive for employers to offer and employees to accept coverage as part of their employment contract as employer provided insurance is by far the most prevalent form of coverage in the private sector policy makers look for further expansion of this base as a way to insure the uninsured while avoiding direct public financing as a way to increase employer based health insurance coverage some states either have or are considering government mandates that require employers to provide insurance to certain types of workers 1 the state of hawaii requires private sector employers to offer health insurance to all workers who work for more than 20 h a week and requires these workers to have insurance the state of california is currently considering a similar mandate there is a considerable interest from policy makers on the effects of such mandates on labor market outcomes in this study we report on an experiment that was designed to provide some insights about possible effects of alternative health insurance regulations on the competitive labor market with a particular focus on mandates since we only considered a competitive market setting with complete contracts and no wage rigidities our results may not be directly applicable to all labor market situations 2 however the study provides useful insights about the interaction of health insurance benefit provision wages and employment structure for labor markets where the competitive wage setting and the complete contracts assumptions are reasonable with these limitations in mind our results can be also generalized to other types of employer provided fringe benefits such as paid vacations or pension plans as any government intervention health insurance regulation may affect the labor market theory predicts that in perfectly competitive labor markets health insurance creates no distortionary effects on the labor market equilibrium as long as the coverage is not mandated and there are no wage rigidities 3 all workers who value insurance above its cost of provision are offered insurance and accept it the wages are adjusted downward see rosen 1986 and gruber 2000 summers 1989 used a simple supply and demand analysis to show that the effect of increases in premiums on equilibrium labor hours and wage depends both on the elasticity of labor demand and labor supply and on how fully workers value changes in the cost of health insurance if the demand or the supply of labor is completely inelastic or if workers fully value the insurance then an increase in the premium would result in an equal decrease shift in wages

merit order effects of renewable energy and price divergence in california s day ahead and real time electricity markets abstract we answer two policy questions 1 what are the estimated merit order effects of renewable energy in the california independent system operator s caiso s day ahead market dam and real time market rtm and 2 what causes the hourly dam and rtm prices to systematically diverge the first question is timely and relevant because if the merit order effect estimates are small california s renewable energy development is of limited help in cutting electricity consumers bills but also has a lesser adverse impact on the state s investment incentive for natural gas fired generation the second question is related to the efficient market hypothesis under which the hourly rtm and dam prices tend to converge using a sample of about 21 000 hourly observations of caiso market prices and their fundamental drivers during 12 12 2012 04 30 2015 we document statistically significant estimates p value 0 01 for the dam and rtm merit order effects this finding lends support to california s adopted procurement process to provide sufficient investment incentives for natural gas fired generation we document that the rtm dam price divergence partly depends on the casio s day ahead forecast errors for system loads and renewable energy this finding suggests that improving the performance of the caiso s day ahead forecasts can enhance trading efficiency in california s dam and rtm electricity markets

stock option grants to target ceos during private merger negotiations abstract unscheduled stock options to target chief executive officers ceos are a nontrivial phenomenon during private merger negotiations in 920 acquisition bids during 1999 2007 over 13 of targets grant them these options substitute for golden parachutes and compensate target ceos for the benefits they forfeit because of the merger targets granting unscheduled options are more likely to be acquired but they earn lower premiums consequently deal value drops by 62 for every dollar target ceos receive from unscheduled options conversely acquirers of targets offering these awards experience higher returns therefore deals involving unscheduled grants exhibit a transfer of wealth from target shareholders to bidder shareholders

the effect of unionism on fringe benefits this study analyzes the impact of unionism on fringes paid to production workers using data on individual establishments it compares fringe expenditures in establishments having the same level of compensation per hour and finds that unionism raises the share of compensation allotted to fringes particularly to pensions vacation pay and life accident and health insurance in addition since unionism also raises the straight time wage rate itself a prime determinant of expenditures on fringes unionism has a very sizeable impact on total fringe expenditures as well as on the fringe share of compensation the union fringe effect exceeds in percentage terms the union wage effect and is sufficiently large to suggest that standard union wage studies understate the union effect on total compensation the study also compares the fringe expenditures of production and non production workers within the same establishment controlling for within establishment pay policies the findings suggest that the pres

how elastic is the firm s demand for health insurance abstract we investigate the impact of tax subsidies on the firm s decision to offer insurance and on conditional firm spending on insurance we do so using the micro data underlying the employment cost index which has a major advantage for this exercise the matching of very high quality compensation data with information on a sample of workers in the firm we find that overall there is a moderately sized elasticity of insurance offering with respect to after tax prices 0 25 and a larger elasticity of insurance spending 0 7 we also find that the elasticities are driven primarily by small firms for whom the elasticity is larger and we find that there is significant value added to this employer based data replicating methods from standard micro data sources in our data lead to misleading estimates of these key parameters our simulation results suggest that major tax reform could lead to an enormous reduction in employer provided health insurance spending

what are occupational pension plan entitlements worth in britain the acquisition of rights by workers in private pension plans underpins retirement behaviour recruitment policy and wage structure but there is controversy as to how these individual pension rights should be valued the paper combines four data sets to calculate pension entitlements for a sample of 3000 british workers in 1987 expected scheme tenure is a key variable in valuation younger workers and women face greater initial uncertainty as to their pension outcomes which is resolved as job tenure lengthens given the distribution of tenure durations many employees would obtain higher returns in defined contribution schemes than in a typical final salary defined benefit plan

did a local distribution company procure prudently during the california electricity crisis abstract to manage cost risk prudent procurement of electric power requires that some portion of a buyer s energy demand be met through long term contracting under cost of service regulation or performance based regulation a local distribution company ldc should be allowed to fully recover all prudently incurred power procurement costs however the regulatory test of prudence is an ex post review with the threat of disallowance this paper presents an economic analysis of procurement prudence involving a small ldc bear valley electric service bves which serves a resort area in southern california the key findings are a high and volatile prices and rolling blackouts characterized the market environment faced by the owner of bves southern california water company scwc at its signing of a 5 year fixed price contract b scwc was a price taker with no incentive to act imprudently c the contract was obtained via a competitive bidding process d the contract price was comparable to the benchmark price of contemporaneous contracts e the fixed price contract was economic when compared to available alternatives and f despite a e a negotiated settlement with the state regulator and a large user resulted in substantial disallowance the policy implication is that a regulator should approve a prudent procurement plan proposed by an ldc to remove the unreasonable risk of an ex post review if the ldc strictly adheres to the plan the resulting electricity purchases are per se prudent and should entitle the ldc to full cost recovery

union nonunion compensation differentials across plant sizes evidence from cps 1983 previous empirical work on the relationship between plant size and union nonunion differentials has focused either on wages podgursky 1986 or benefits bramley wunnava and robinson 1989 freeman 1981 this note extends this research by simultaneously focusing on both wages and benefits there are several arguments that can be made in explaining union nonunion differentials across plant sizes 1 union threat effects 2 efficiency wage effects and 3 wage dispersion effects our study focuses on measuring the union nonunion differential in total compensation for this end estimates of total compensation are obtained using mellow s suggestion 1982 for combining hourly wage information with qualitative data on pensions and health insurance and ross s imputations 1989 for holidays and vacations benefits our results based on the may 1983 cps supplemented by bls data on pensions health insurance holidays and vacation benefits indicate significant union nonunion total compensation differentials exist only for workers in establishments with less than 500 workers these results are consistent with podgursky s wage differential findings

tax structure and tax compliance a model of individual tax compliance behavior including evasion and avoidance is developed and estimated the model recognizes the importance of marginal income tax rates payroll tax contributions and benefits and the probabil ity of detection and the penalty on unpaid taxes share equations for avoidance evasion and reported income are estimated using individual level data the estimation results indicate that the tax base rises with higher benefits for payroll tax contributions and falls with higher marginal tax rates the base also falls with more severe penalties and more certain detection of evasion as individuals substitute towards avoid ance income t he methods by which individuals reduce their tax liabilities take a variety of legal and illegal forms all of which are influenced at least in part by incentives created by the tax structure these methods can be broadly classified as avoid ance and evasion tax avoidance is any legal activity that lowers taxes such as worker substitu tion between wage and nonwage compensation tax evasion is the reduction in tax liabilities by illegal means such as underreporting income on tax returns despite extensive but separate literatures on avoidance and evasion we know very little about the tax base response to changes in tax structure it is the purpose of this paper to examine the role that the tax structure plays in compliance there are several reasons for the persistence of the compliance puzzle most prominent is the absence of detailed individual data that would allow a full empirical specification of all factors affecting compliance this difficulty is most evi dent when searching for individual data on the evasion compliance decision even when avail able data have never allowed in the same work the construction of both tax and audit variables 1 clearly data availability is even more problem atic when looking at the choice among evasion avoidance and reported income in addition pre vious work has not looked at the avoidance evasion compliance decision as a joint process even though these decisions are made simultane ously 2 further both strands of the literature have ignored another factor that may affect the compliance decision the benefits that accrue from participation in payroll programs if benefits are tied only to taxable income then their presence gives individuals an incentive to pay taxes in short there has been no empirical work that analyzes the effects of tax rates probabilities penalties and payroll benefits on avoidance and evasion choices of individuals in this paper we provide such an analysis we first develop a theory of individual choice among the three types of compensation we then esti mate the resulting share demand equations using a unique data set which has detailed information on the compensation paid to roughly one quarter of the labor force in jamaica in 1983 from these data we are able to derive measures of reported taxable income evasion income and avoidance income for individual workers in the formal sec tor we are also able to construct measures of the marginal income tax rate marginal payroll taxes and benefits the probability of detection and the penalty on evasion for individual workers we are therefore able to estimate for the first time the responses of workers to the full range of tax structure parameters section i presents the theoretical model of worker compensation choice and the empirical specification of the model section ii discusses the jamaican tax system data and variable con struction are discussed in section iii estimation results are presented in section iv the final section summarizes the main results

a medium term decision model for discos forward contracting and tou pricing time varying prices by motivating customers to reduce their consumption in peak periods propel the electricity industry towards a higher efficiency compared to that of common flat prices focusing on time of use tou sale prices this paper establishes a stochastic model for the medium term decision making problem faced by a distribution company disco the developed model deals with the disco s decisions on the level of involvement in forward contracts and in the pool as well as the sale prices offered to customers the demand response to tou prices is captured using a price elasticity matrix pem the objective is to maximize the disco s profit while the exposure risk imposed by uncertainties is limited to a given level the model is formulated as a mixed integer linear programming milp problem that can be effectively solved via commercial software packages a typical finnish 20 kv urban distribution network is used to demonstrate the effectiveness of the developed model

tax policy and the demand for health insurance estimates of the price and income elasticities of demand for health insurance are derived from econometric estimates of the parameters of a discrete choice model of health insurance demand using data from a survey of plan choices among a sample of federal government employees the estimated income elasticity 0 01 is similar to most previous estimates the estimated price elasticity 0 16 is in absolute value much less than the earlier previous estimates and somewhat less than the more recent previous estimates possible causes of these differences in price elasticity estimates are discussed

health insurance the tradeoff between risk pooling and moral hazard choosing optimal health insurance coverage involves a trade off between the gain from risk reduction and the deadweight loss from moral hazard this paper examines this trade off empirically by estimating both the demand for health insurance and the demand for health services it relies on data from a randomized controlled trial of cost sharing s effects on the use of health services and on the health status for a general non elderly population

an international review of the implications of regulatory and electricity market structures on the emergence of grid scale electricity storage abstract energy storage systems ess have the potential to make a significant contribution to planning and operation practises in power systems while ess can be used to provide multiple benefits in the power sector widespread use has been restricted by high technology costs lack of deployment experience and the barriers and uncertainties caused by the present electricity market and regulatory structures that were designed for conventional electricity systems this paper reviews countries with high renewable targets and with significant current or planned ess deployments to ascertain the common problems affecting the use of ess on the grid and to establish where changes have been made or proposed to the electricity market and regulatory frameworks three major problems were identified as the undetermined asset class for ess and unbundled electricity system limiting stakeholders from determining and realising multiple ess benefits low electricity market liquidity and changing market conditions and a lack of common standards and procedures for evaluating connecting operating and maintaining ess based on the established barriers recommendations to update or create policies regulation and market arrangements to increase the viability and wider use of grid level ess are discussed the three key regulatory and policy recommendations were identified as an alignment of renewable policies to that of ess creating a separate asset class for ess and associated rules for regulated and competitive operations and standardising assessment frameworks connection and operational procedures for the use of ess finally three main electricity market recommendations include updating rules to support simultaneous ess operation across wholesale ancillary services and capacity markets updating market rules to allow compensation for flexible and highly accurate responsive demand and generation technologies such as ess and updating market ancillary services energy requirements

the implications of job matching for retirement health insurance and leave benefits this paper focuses on potential reasons for variations in benefit packages in particular variations in the availability of retirement health insurance and leave an important feature of our analysis is that we do not start with heterogeneity in workforces to explain fringe benefit differences across employers it would be straightforward to say that differences across employers in fringe benefit packages simply represent differences in the preferences of their workforces rather we focus on heterogeneity across employers as an important source of differences in fringe benefit packages preliminary evidence is found supportive of the predicted differences in the likelihood of such fringe benefits as retirement health insurance and leave based upon two variables the extent of on the job training offered by the employer and the size of the employers we also examine the implied links between these fringe benefits and such variables as average tenture and the proportion of the workforce that is female

taxes and the number of fringe benefits received abstract discussion about tax policy towards fringe benefits has often assumed that taxing benefits would cause a large change in the composition of employee compensation previous evidence though indicates that changes in marginal tax rates do not have a large effect on expenditures on major fringe benefits as a share of total compensation this paper examines whether employees respond to higher tax rates by getting additional kinds of fringe benefits the results suggest that the effect of tax rates on the probability of receiving additional fringe benefits is quite small

taxes fringe benefits and faculty the growth of employee benefits in academe has closely paralleled their economy wide growth this study estimates a complete system describing the demand for benefits and wages using panel data on 1477 institutions of higher learning the demand for benefits is very responsive to changes in real income and the tax price of benefits these conclusions are robust with respect to varying definitions of the tax price treating it as endogenous and accounting for unmeasured individual effects on demand simulations suggest that the tax reform act of 1986 sharply reduced the demand for benefits extrapolating the impact to the entire economy the annual flow of compensation shifted away from benefits by at least 15 billion copyright 1992 by mit press

what is a public sector pension worth we measure accruals in defined benefit db pension plans for public and private sector workers in britain using typical differences in scheme rules and sector specific lifetime age wage profiles by sex and educational group we show not just that coverage by db pension plans is greater in the public sector but that median pension accruals as a percentage of salary are more than 6 higher among db covered public sector workers than covered private sector workers this is largely driven by earlier normal pension retirement ages but also by differences in earnings profiles across the sectors

a critical assessment of the hong kong government s proposed post 2008 regulatory regime for local electricity utilities abstract in december 2005 the hong kong government issued a consultation paper on future development of the electricity markets in hong kong stage ii consultation proposing a post 2008 regulatory regime upon the expiration of the existing regulatory contract between the hong kong government and each of the two local electricity utilities we assess the proposal using the criteria of safe reliable and environmentally friendly service at the lowest rates that will allow the utilities reasonable returns on their investments we caution that if fully adopted the highly risky proposal may lead to less reliable service without the compensating benefits to the environment

auctions versus negotiations which is the more profitable way to sell a company an auction with no reserve price or an optimally structured negotiation with one less bidder we show under reasonable assumptions that the auction is always preferable when bidders signals are independent for affiliated signals the result holds under certain restrictions on the seller s choice of negotiating mechanism the result suggests that the value of negotiating skill is small relative to the value of additional competition the paper also shows how the analogies between monopoly theory and auction theory can help derive new results in auction theory jel d44 g34 there are close analogies between standard price theory and the theory of auctions in an absolute english auction in which the price rises continuously until only one bidder remains and the seller is required to accept the final bid the sale price equals the lowest competitive price at which supply equals demand in the theory of optimal auctions the seller is treated as a monopolist who can choose any

a 100 year review of electricity policy in ireland 1916 2015 abstract over the past century ireland s electricity sector has undergone a significant transformation this paper documents the nation s struggle to build an electricity system to improve security of electricity supply through portfolio diversification and to promote indigenous energy sources this was a challenge for an electrically isolated island with little natural resources the paper also identifies the ineffective policy decisions that left ireland exposed to the 1970s energy crises the crises did however provide a clear impetus for focusing irish energy policy going forward the successful deployment and integration of large scale wind power was due to strong national and supranational policy decisions in 2015 ireland had the third highest wind energy share of national electricity demand 22 8 of all iea wind member countries the paper also traces ireland s transition through market reform regional fragmentation and looks onwards to the eu internal market for electricity in essence this paper provides a holistic view of the implications of various policy decisions on the electricity sector along with the stresses of external factors on the electricity market and should be useful for policy makers elsewhere faced with similar decisions

search for nonwage job characteristics a test of the reservation wage hypothesis previous structural models of job search behavior have been based upon the reservation wage property this article provides estimates of a more general search model that nests models with the reservation wage property the estimates lead to rejection of the reservation wage property the model includes hours of work in the utility function but other nonwage job characteristics can be included as well an experiment based on the estimated parameters indicates that a significant proportion of job offers would be mistakenly predicted to be accepted or rejected under the restrictions implied by the reservation wage property

china s electricity market oriented reform from an absolute to a relative monopoly abstract the market oriented reform in electricity industry has become a global trend since 1980s although china s electricity industry has been reformed since 1978 the substantial reform has not been conducted until 1985 before 1985 china s power industry had been absolutely monopolized by the central state owned companies the absolute monopoly has been broken since 1985 when the chinese government opened doors for non central state owned investment entities and foreign investors in power supplies in order to solve the chronic power shortage in 2002 the comprehensive electricity reform plan entitled scheme of the reform for power industry was enacted however implementation of this plan was delayed due to electricity supply shortages even worse a new kind of monopoly has been developed under the background the state advances the private sector retreats in late years in some sense the former absolute monopoly has transformed the current relative monopoly we contend that the relative monopoly has reversed the market oriented reform in china s electric industry if the relative monopoly remains unchanged it will be harmful to public welfare

substitution between wage and nonwage benefits you gotta be kidding ollie you re just robbing yourself schuylkill mutual offers a terrific deal on keogh and we could plug you in in fact we advise plugging you in on the corporate end so not a nickel comes out of your personal pocket it comes out of the corporate pocket and there s that much less for uncle to tax these poor saps carrying their own premiums with no company input are living in the dark ages there s nothing shady about rigging it this way we re just using the laws the government has put there they want people to take advantage it all works to up the gross national product you know what i mean by keogh don t you you re looking kind of blank john updike p 296

public choice when services are costs the divergent case of assessment administration despite a strong body of empirical support many political scientists remain suspicious of public choice theory that suspicion is often focused on the tendency of public choice proponents to generalize an ideal institutional structure to nearly every policy area they examine this arises in part because public choice analysts tend to study goods and services that can be characterized by a single specification of self interest this paper applies public choice analysis to property tax assessment administration a local government service with political characteristics quite unlike those commonly examined to assess the flexibility of the model and the generalizability of its usual recommendations on institutional stucture surprisingly application of public choice theory in this case leads to a set of institutional recommendations similar to those associated with traditional reform theory
