durable goods and product obsolescence the issue of product obsolescence is addressed by examining the optimal sales strategy of a monopolist firm that may introduce an improved version of its current product consumers expectations of a forthcoming product lowers the price that they are willing to pay for the current product because of its loss in value due to obsolescence the new product is characterized by consumers increased willingness to pay and by its competitive interaction with the old product these characteristics affect the tradeoff that the firm makes between the cost of waiting for new product sales versus the cost of cannibalizing these sales we analyze the effect of these characteristics of the new product on the firm s optimal sales strategy we consider the various policy measures available to the firm including limiting initial sales in order to lower cannibalization of the new product buying back the earlier version of the product in order to generate greater demand for the new product and announcements of future product introductions we find that for modest levels of product improvement the firm s optimal policy is to phase out sales of the old product while for large improvements a buy back policy is more profitable lastly we find that the firm is better off if it informs consumers whether a new product is forthcoming

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

assessment of public acceptance and willingness to pay for renewable energy sources in crete abstract the aim of this study is to analyse and to evaluate the citizens public acceptance and willingness to pay wtp for renewable energy sources res in crete for this purpose a contingent valuation study was conducted using a double bound dichotomous choice format to elicit people s wtp and factors affecting it residents of 1440 households all over crete were interviewed face to face major conclusions can be used as a basis for sustainable energy planning for policies and the formulation of awareness campaigns and for res investment programs and projects in order to prepare implementation conditions and enhance public acceptance of renewable energy investments and programmes mean wtp per household was found to be 16 33 to be paid quarterly as an additional charge on the electricity bill larger willingness to pay was reported by those with high family income and residence size those having a higher level of energy information and awareness concerning climatic change those who have invested in some energy saving measures and those who suffer from more electricity shortages than others

revisiting the employment impact of offshoring abstract the productivity gains due to offshoring may in part accrue to workers this paper estimates the magnitude of these gains and compares it to the magnitude of employment loss due to worker displacement a model based on the production task framework from grossman and rossi hansberg 2008 is used to demonstrate that the effect of offshoring depends on the intensity of use of these tasks and ultimately impacts domestic employment through three channels a direct displacement effect which negatively impacts employment an output effect generated by the productivity gains from offshoring which reorganizes and increases aggregate production in the economy and impacts domestic employment positively and a substitution effect among factors and tasks which has an ambiguous effect using the model s structure as a roadmap and applying it to detailed u s manufacturing sector data over 2001 2007 results from gmm 3sls regressions provide overall support for the structure and predictions of the tasks model of offshoring in particular the economic magnitude of the productivity gains is found to have been important

trade ins and introductory offers in a monopoly we model the commonly used marketing practices of offering discounts to either repeat buyers trade ins or new buyers introductory offers of a quasi durable good we analyze these practices in terms of their potential for intertemporal and third degree price discrimination in our two period model the monopolist sets a first period price that segments the second period market optimally into holders and nonholders of the good in the second period different prices are quoted to the two market segments we present three versions of the model with varying assumptions on consumers rationality

outsourcing imports and labour demand this paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in german manufacturing sectors we derive and estimate a factor demand system based on the generalised box cox cost function nesting both the normalised quadratic and the translog functional form we find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non labour inputs similarly the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution

commitment and monopoly pricing in durable goods models this article investigates the issue of commitment by a durable goods monopolist two models of the interaction between durability recycling and market power are compared the two differ according to the ability f the seller to credibly commit to a given salec qtrn egy this article takes the standard durable goods monopoly model extends it to allow for depreciation and compares the monopoly markup with swan s predicted markup for a recycled good the difference between the two models is shown to reduce to a single parameter in the markup equation

consumer demand for green power and energy efficiency abstract this article examines reported willingness to pay for electric utility investments in renewable energy and energy efficiency resources using the results of deliberative polls conducted by electric utilities in texas 1 age education and salary tend to affect reported willingness to pay for utility investments in these resources intensive exposure to information about energy resource issues led to an increase in the number of respondents interested in paying a modest premium to support investments in both renewable energy resources and energy efficiency however average reported premiums actually declined following the polls as very high outlier responses moved to more reasonable values following the polls these results support the contention that informed dialogue about energy alternatives will result in broader interest in providing a modest level of support for these resources

foundations of dynamic monopoly and the coase conjecture subgame perfect equilibria are characterized for a market in which the seller quotes a price each period assume zero costs positive interest rate continuum of buyers and some technical conditions if buyers valuations are positive then equilibrium is unique buyers strategies are stationary and the price sequence is determinant along the equilibrium path but possibly randomized elsewhere otherwise a continuum of stationary equilibria can exist but at most one with analytic strategies coase s conjecture is verified for stationary strategies reducing the period length drives all prices to zero or the least valuation connections to bargaining models are described journal qf economic literature classification

revenue management for durable goods using trade ins with certified pre owned options abstract the economics research suggests that firms can use trade ins as a revenue management device for price discrimination between new and replacement buyers of durabprle goods offering different prices to different groups of customers creates a market segmentation effect this study examines such an effect by considering trade ins and certified pre owned options for a durable goods firm where certified pre owned cpo represents the used goods market generated from the return flow of trade in transactions the optimal pricing and or trade in rebate is determined and the strategic choice between the two options is examined an analytical model is developed that incorporates the key durable goods features into model formulation specifically the deterioration rate or durability in a reverse measure and the variation in quality of the used goods our research findings indicate that i the magnitude of trade in rebates increases with the deterioration rate and quality variation ii the segmentation effect outweighs the cannibalization effect when the deterioration rate is moderately high iii the strategic choice of trade ins and cpo options is critically dependent on these two features and iv the majority of profit improvement is generated from trade in provisions although the cpo option can serve as a second profit boosting device

do price ceilings abroad increase u s drug prices abstract for a monopolist who price discriminates between two markets how does the imposition or lowering of a binding price ceiling in one market affect the price in the other unregulated market our analysis reveals that the imposition or lowering of the price ceiling may actually lower the price in the unregulated market

bundling of substitutes or complements abstract the adams yellen two good bundling framework is generalized to allow the goods to be substitutes or complements general theorems on price change effects are given a monopolist may find it most profitable to offer the goods only as a bundle even if they are imperfect substitutes or to not bundle the goods even if they are complements if one good is competitively sold a monopoly producer of the other good can never increase profits by offering his good only as part of a bundle however such a monopolist might profitably offer his good in both bundled and unbundled form to price discriminate even if the two goods are substitutes

cyclic pricing by a durable goods monopolist in the model of this paper a monopoly seller of a durable good holds periodic sales as a means of price discrimination a new cohort of consumers enters the market in each period interested in purchasing the good either immediately or after a delay within each cohort consumers vary in their tastes for the good under broad conditions the seller will vary the price over time in most periods he will charge a price just low enough to sell immediately to consumers with a high willingness to pay periodically however he will drop the price far enough to sell to an accumulated group of consumers with a low willingness to pay

international outsourcing and factor prices with multistage production we develop a dual representation of the technology of international fragmentation for an industry using 2 factors in a continuum of stages we then derive a generalised factor price frontier which incorporates an endogenous adjustment of the margin of fragmentation using this frontier in a 2 2 general equilibrium model we investigate the role of outsourcing in the adjustment to a decline in the final output price of the multistage industry and the attendant factor price effects we also explore the implications of an improved technology of international fragmentation on the margin of fragmentation and on domestic factor prices

from sick man of europe to economic superstar germany s resurgent economy in the late 1990s and into the early 2000s germany was often called the sick man of europe indeed germany s economic growth averaged only about 1 2 percent per year from 1998 to 2005 including a recession in 2003 and unemployment rates rose from 9 2 percent in 1998 to 11 1 percent in 2005 today after the great recession germany is described as an economic superstar in contrast to most of its european neighbors and the united states germany experienced almost no increase in unemployment during the great recession despite a sharp decline in gdp in 2008 and 2009 germany s exports reached an all time record of 1 738 trillion in 2011 which is roughly equal to half of germany s gdp or 7 7 percent of world exports even the euro crisis seems not to have been able to stop germany s strengthening economy and employment how did germany with the fourth largest gdp in the world transform itself from the sick man of europe to an economic superstar in less than a decade we present evidence that the specific governance structure of the german labor market institutions allowed them to react flexibly in a time of extraordinary economic circumstances and that this distinctive characteristic of its labor market institutions has been the main reason for germany s economic success over the last decade

sales and consumer lock in this paper examines the dynamically consistent price path for a new product monopolist unable to commit to future prices when consumers must incur setup costs of adopting the product the authors find that setup costs give rise to a price path with introductory sales along the path periods of high prices during which only locked in or captive customers buy the product alternate with sales low price periods during which new customers adopt the product as the stock of captive customers increases over time sales become less frequent after the customer base reaches some critical level no further sales take place they show that the monopolist may hold a sleeping patient in which initial sales of the product are postponed to avoid locking into a high pricing strategy that ignores new customers copyright 1989 by the london school of economics and political science

a note on expanding networks and monopoly pricing we obtain explicitly the optimal path of prices for a monopolist operating in a network industry during a finite number of periods we describe this optimal path as a function of network intensity and horizon length and show that the prices are increasing in time and that for very low network intensity or very high horizon length the monopolist will offer the good at zero price in the initial period

offshoring tasks and the skill wage pattern the paper investigates the relationship between offshoring wages and the occupational task profile using rich individual level panel data our main results suggest that when only considering within industry changes in offshoring we identify a moderate wage reduction due to offshoring for low skilled workers though wage effects in relation to the task profile of occupations are not estimated with sufficient precision however when allowing for cross industry effects of offshoring i e allowing for labor mobility across industries negative wage effects of offshoring are quite substantial and depend strongly on the task profile of workers occupations a higher degree of interactivity and in particular non routine content effectively shields workers against the negative wage impact of offshoring

understanding the role of trade ins in durable goods markets theory and evidence the act of trading in a used car as partial payment for a new car resonates with practically all consumers such transactions are prevalent in many other durable goods markets ranging from golf clubs to ct scanners what roles do trade ins play in these markets what motivates the seller to set up a channel to facilitate trade ins intuitively accepting a trade in would appear to stimulate demand for the producer s product but facilitating the resale of these used goods that substitute for new goods might also increase cannibalization although such transactions involve billions of dollars we know relatively little about this practice from the extant research literature this paper develops an analytical model that incorporates key features of real world durable goods markets i coexistence of new and used goods markets ii consumer heterogeneity with respect to quality sensitivity iii firms that anticipate the cannibalization problem arising from the coexistence of new and used goods and iv lemon problems in resale markets whereby sellers of used goods are better informed than buyers about the quality of their particular item in our analysis a trade in policy amounts to an intervention by the firm in the used goods market which reduces inefficiencies arising from the lemon problem it motivates owners to purchase new goods and reduces their proclivity to hold on to purchased goods because of the low price the latter would fetch in a lemon market we also show that trade in programs are more valuable for less reliable products as well as for products that deteriorate more slowly our analysis shows that producers in durable goods markets should consider trade in programs as a matter of routine despite cannibalization concerns arising from a more active resale market a producer s profits will inevitably rise from introducing trade ins given pervasive lemon problems we test the key predictions of the model about price and volume of trade by assembling a data set of transactions of u s automobile consumers and find broad support for our model

margins of multinational labor substitution multinational labor demand responds to wage differentials at the extensive margin when a multinational enterprise mne expands into foreign locations and at the intensive margin when an mne operates existing affiliates across locations we derive conditions for parametric and nonparamtric identification of an mne model to infer elasticities of labor substitution at both margins controlling for location selectivity prior studies rarely found foreign wages or operations to affect employment our strategy detects salient adjustments for german mnes with a one percent increase in german wages german mnes add 2 000 manufacturing jobs in eastern europe at the extensive margins and 4 000 jobs overall a converse one percent drop in eastern european wages is associated with an overall withdrawal of 730 mne jobs from germany

citizen versus consumer challenges in the uk green power market abstract this paper investigates the potential advantages and disadvantages of green power products as opposed to the traditional fossil fuel levy which was the uk s chosen tax regime as a means of developing renewable energy in the uk willingness to pay for electricity generated from renewables is investigated results indicate that willingness to pay varies with social status and income however results demonstrate that there is a significant minority in full support of some sort of fiscal initiative electricity generated from renewables is a concept supported by the majority however given the stated willingness to pay it is unlikely that any new renewable capacity will result from green tariff schemes in the near term it is concluded that the green citizen must continue to co exist with the green power purchaser if the uk is to make any significant improvement in the contribution of renewable energy to electricity demand the authors would like to acknowledge the support of irene lorenzoni and jane powell of the centre for social and economic research on the global environment university of east anglia leicester energy efficiency advice centre and leicester energy agency

norms and economic motivation in the swedish green electricity market abstract the purpose of this paper is to provide an econometric analysis of the most important determinants of swedish households choice to pay a price premium for green electricity we draw on recent developments in the literature on integrating norm motivated behavior into neoclassical consumer theory and assume that individuals have a preference for keeping a self image as a morally responsible person consumer behavior in the green market place will then be heavily determined by how purchases of different goods affect this self image the analysis is based on postal survey responses from 655 swedish households which are analyzed within a binary choice econometric framework the results indicate that the impact of choosing green on the household budget largely influences the choice between green and brown electricity as does the degree of perceived personal responsibility for the issue and the felt ability to affect the outcome in a positive way we find limited support for the notion that perceptions about others behavior in general affect individual moral norms and ultimately expressed behavior but this is also complemented by the influence of explicit social influence the difficulty in observing others purchases makes it however difficult to distinguish between social and moral norms in the case of green electricity

using contingent valuation to explore willingness to pay for renewable energy a comparison of collective and voluntary payment vehicles abstract this study uses a split sample dichotomous choice contingent valuation survey of 1574 u s residents to explore willingness to pay wtp for renewable energy under collective and voluntary payment vehicles and under government and private provision of the good we also evaluate the impact of participation expectations on stated wtp we find some evidence that when confronted with a collective payment mechanism respondents state a somewhat higher wtp than when voluntary payment mechanisms are used similarly private provision of the good elicits a somewhat higher wtp than does government provision we also find that contingent valuation responses are strongly correlated with expectations for the wtp of others our results shed light on strategic response behavior and the incentive compatibility of different cv designs and offer practical insight into u s household preferences for how to support renewable energy

can renewable energy be financed with higher electricity prices evidence from a spanish region abstract in this paper we estimate the willingness to pay for mix of renewable sources of electric power by means of a discrete choice experiment survey conducted in spain in 2010 two main categories of power supply attributes are explored source of renewable power wind solar and biomass and the origin of such power the findings suggest that most consumers are not willing to pay a premium for increases in the shares of renewable in their electricity mix for two of the three renewable sources considered wind and biomass an increase of the renewable mix would require a discount instead we record positive willing to pay for increases in the share of both solar power and locally generated power however preferences for types of renewable solar and wind are found to be heterogeneous by classifying respondents in two groups according to the implied importance of the share of renewable sources in their power mix we identify a market segment consisting of 20 of respondents that could promote renewable energy in the absence of subsidies this is because such a segment shows willingness to pay higher than the current feed in tariffs

services offshoring and its impact on productivity and employment evidence from germany 1995 2006 economists have recently recognised services offshoring as an important influence on domestic labour market outcomes services are of particular interest since their significance has grown in terms of both quantity and quality only one and a half decades ago most services were considered non tradable but the emergence and development of new information and communication technologies has made many services internationally tradable the liberalisation of international trade in services trade has further accelerated the volume of services trade our econometric estimations focus on services offshoring by german manufacturing sectors we use revised input output data from 1995 to 2006 we first estimate the impact of services offshoring on labour productivity we then measure the effects of services offshoring on labour demand the results show that services offshoring increased sectoral labour productivity but reduced german manufacturing employment the overall results suggest that labour demand decreased over 1995 2006 because labour reducing productivity and substitution effects dominated labour augmenting scale effects from services offshoring

service offshoring and firm employment abstract major technological advances have recently spurred a new wave of offshoring in services which used to be non tradable should service workers in developed countries worry about their jobs trade theory has given a nuanced answer to this question suggesting that efficiency gains from offshoring may counteract direct job losses which leaves the predicted net effect ambiguous this paper investigates the employment effects of service offshoring in a newly combined and exceptionally detailed panel dataset covering almost the entire universe of german firms service imports over the years 2001 2013 it exploits firm specific export supply shocks by partner countries and service types as an instrumental variable to find that service offshoring has increased firm employment in line with the canonical trade in tasks model the employment gains are greater in firms with higher initial levels of service offshoring

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

the strategic role of exchange promotions an exchange promotion allows consumers to turn in an old good and receive a discount toward the purchase of a new product the old good that is turned in can either be within the same category as the new good or it may be in a different category for example one can turn in an old cd player to count toward a new cd player a within category exchange or traditional trade in or toward a new television a cross category exchange this paper studies both within category and multicategory exchange promotions and analyzes their similarities and differences in a competitive setting with two firms we model exchange promotions and establish the equilibrium outcomes we find that categories in which consumers have a high level of waste aversion are more likely to have multicategory exchange promotions rather than within category or no promotions multicategory exchange promotions can increase both consumers replacement purchases and their new purchases interestingly we also find that strategic considerations can lead to a prisoner s dilemma outcome in which neither firm offers any kind of exchange promotion however waste aversion and multicategory exchange promotions can give firms stronger incentives to get out of the prisoner s dilemma outcome

employment job turnover and trade in producer services uk firm level evidence abstract we provide the first firm level evidence of the impact of the trade in producer services offshoring on the labour market using a new data set from the uk that measures trade in services at the firm level we find no evidence that importing intermediate services is associated with job losses or greater worker turnover using regression to control for observable differences between firms that import service inputs and those that do not we show that firms that start importing intermediate services experience faster employment growth than equivalent firms that do not this seems likely to be the result of positive demand shocks which cause a simultaneous increase in employment output and use of imported service inputs

stuck between a roc and a hard place barriers to the take up of green energy in the uk abstract this paper examines the uk mechanisms for ensuring future investment in renewable energy through consumer adoption of green energy tariffs and the renewable obligation certificate roc system using a national survey and focus groups the stated willingness by uk customers to pay a premium for renewable or green energy and actual take up of such tariffs is assessed substantial differences between willingness to pay for and the adoption of green energy tariffs are reported this disparity is linked to a range of factors including consumer confusion lack of supply complexities of constructing green source tariffs under the roc system and a lack of customer trust it is concluded that the re definition of the green energy market in favour of green source tariffs greater direct compliance with the renewable obligation by addressing supply constraints and efforts in providing clearer information and choices for consumers via a compulsory green energy accreditation scheme are required if willing consumers are to contribute to investment in renewable energy

optimal strategies for trade old for remanufactured programs receptivity durability and subsidy due to its environmental financial and marketing benefits businesses and governments have increasingly embraced remanufacturing however the weak demand for remanufactured reman product severely hinders the implementation of remanufacturing lately trade old for remanufactured tor programs are growing in popularity as they can boost reman product demand in this paper we investigate the conditions when a firm should offer a tor program and how to best implement it our main findings are 1 firms should offer tor programs only when reman product receptivity and new product durability satisfy a certain condition 2 in addition to the reman product receptivity the new product durability also plays a significant role in motivating consumers to participate in tor programs and finally 3 high product remanufacturability and government subsidies are strong incentives for firms to offer their tor programs our analysis provides insights for firms and governments on how to use tor programs to benefit businesses consumers and the environment

willingness to pay for renewable energy evidence from a contingent valuation survey in kenya a modern form of energy in particular electricity for household use is an important vehicle in alleviating poverty in developing countries however access and costs of connecting to this service for most poor in these countries is inconceivable policies promoting electricity connection in rural areas are known to be beneficial in improving the socio economic and health well being for households this paper examines willingness to pay wtp for rural electrification connection in kisumu district kenya using the contingent valuation method cvm a nonparametric and a parametric model are employed to estimate wtp values for two electricity products grid electricity ge and photovoltaic pv electricity the results indicate that respondents are willing to pay more for ge services than pv and households favoured monthly connection payments over a lump sum amount some of the policies suggested in this paper include subsidizing the connection costs for both sources of electricity adjusting the payment periods and restructuring the market ownership of providing rural electricity services

post unification wage growth in east germany following monetary union with west germany in 1990 the real wage of east german workers rose 83 i use the german socio economic panel data to investigate the determinants of wage growth and assess whether they are consistent with efficient restructuring although job changing rates were initially high the share of wage growth that accrued to movers was little higher than in the west suggesting that the incentives to move were too low for 1990 to 1991 the biggest gainers were low wage workers generally and women and the less educated specifically for 1991 to 1996 the biggest gainers were women and the better educated

a theory of economic obsolescence a new generation of durable goods makes an old generation economically even if not physically obsolete economic obsolescence due to technological innovation requires the durable goods monopolist to implement price discrimination in two dimensions both between consumers with different valuations and between consumers with different purchase histories equilibrium in the game between the durable goods monopolist and consumers depends on the extent of economic obsolescence and the relative sizes of the consumer groups underinvestment in innovation may take place this contrasts with the standard literature on planned obsolescence where the durable goods monopolist overinvests in durability reducing technology

welfare effects of entry into markets with switching costs in many markets consumers have costs of switching between products that are functionally identical this note shows that entry of efficient low cost competitors into these markets may be socially detrimental in a linear model entry reduces social welfare as conventionally defined in more than half of the relevant parameter space in a more general model there is always a range of values of switching costs for which entry reduces welfare even if the entrant s production costs are lower than the incumbent s copyright 1988 by blackwell publishing ltd

revealed and stated preferences for co2 emissions reduction the missing link abstract in this paper we combine data collected from two strands of literature dealing with revealed preferences expressed by conventional vehicle drivers for fuel price variation and stated preferences expressed by consumers for alternative fuel vehicles we employ a meta analysis approach drawing data on 30 primary studies reflecting two important policy interventions which are fuel price taxation and subsidies for alternative fuel vehicles this is a new contribution in environmental and energy economics in that we rescale all primary information into a unique index which captures consumers economic attitude towards carbon dioxide co2 emission reduction in monetary terms focusing on the transport sector we compute the implicit price for the avoidance of a kilogram of co2 emissions named pco2 explaining the existing heterogeneity from several points of view the results of the meta analysis show that contextual and individual characteristics influence the implicit price for co2 emissions avoidance this implicit price is on average positive in the case of revealed preferences studies whereas it is negative in the stated preferences studies although there are some important geographical differences our results show that fuel taxes could be an important additional instrument for environmental policy

the timing of sales this paper presents a model of intertemporal price discrimination a fixed number of sellers produce a homogeneous good consumers with different preferences enter the market in each period and leave when they make a purchase the sellers typically vary their prices over time charging a high price in most periods but occasionally cutting the price to sell to a large group of customers with a low reservation price in some equilibria all stores lower their price at the same time and to the same level

the informational role of product trade ins for pricing durable goods this research theorizes that sellers of durable goods can utilize inferences about the buyer s willingness to pay based not only on her decision to trade in the old good but also on its characteristics we find empirical support for this theory using transaction data for new car purchases the results support the notion that dealers infer a higher willingness to pay and charge higher prices to consumers who trade in a used vehicle than to those who do not we also find that dealers charge even higher prices to those consumers who trade in used cars that are similar to the new one

willingness to pay for green power in an unreliable electricity sector part 1 the case of the lebanese residential sector abstract a willingness to pay wtp analysis for renewable based electricity is undertaken for the lebanese residential sector a survey of 600 samples was conducted based on a stratified random sampling method in which energy use and expenditures socioeconomic and demographic characteristics were collected four scenarios for wtp for green power were designed to best reflect the possibilities of integrating renewable energy re sources in lebanon s unreliable electricity sector 1 local system covering partial electricity needs 2 local system covering entire electricity needs 3 utility provided green power covering partial electricity needs and 4 utility provided green power covering entire electricity needs the results based on a tobit model highlight the importance of re options that displace completely the diesel generator sets i e options 2 and 4 other parameters such as ownership of the home age perception of trust in government institutions and awareness of re were also found significant in influencing wtp

the politics and economics of offshore outsourcing abstract this paper reviews the political uproar over offshore outsourcing connected with the release of the economic report of the president erp in february 2004 examines the differing ways in which economists and non economists talk about offshore outsourcing and assesses the empirical evidence on the importance of offshore outsourcing in accounting for the weak labor market from 2001 to 2004 even with important gaps in the data the empirical literature is able to conclude that offshore outsourcing is unlikely to have accounted for a meaningful part of the job losses in the recent downturn or contributed much to the slow labor market rebound the empirical evidence to date while still tentative actually suggests that increased employment in the overseas affiliates of us multinationals is associated with more employment in the us parent rather than less

work characteristics firm size and wages a positive wage firm size relationship is well documented in the empirical literature in industrial organization and labor economics firm size seems to proxy various unobserved determinants such as job satisfaction monitoring costs more complex technologies and worker participation in monopoly profits it is generally argued that the greater the possibility of controlling for these latent factors the less likely that a significant size effect will appear this paper attempts to distinguish firm size from other wage determinants for a rich data source for west germany and demonstrates the persistence of the size premium

the internet and international trade in services the scope for growth of trade in services is vast although services currently make up over 60 percent of world production they account for only about 20 percent of world trade a primary reason why international trade in services has been limited is that the performance of many services necessitates physical contact between producers and consumers a condition that renders service provision to distant locations infeasible new technology in particular the internet provides a medium of exchange that overcomes such historical trading hurdles for many services effectively reducing transport costs from infinity to virtually nothing there is ample anecdotal evidence that the internet is having just this sort of an effect on services trade the accounting firm netlink maintains the books for 6 000 employees in reyanosa mexico from their offices in manhattan infosys of india provides softwareconsulting services to international clients including apple computers lucent technologies and microsoft a medical transcription company in south africa its receives digital recordings from abroad electronically and returns a transcribed text file the next day still the question remains as to whether electronic sharing of information is an important enough development to alter significantly the geography of service provision indeed many services need to be tailored to the consumer s needs and monitored for quality and these are likely to be more effective if the provider is close by and speaks the same language in addition in the event of a dispute resolution will be less complicated if both parties are subject to the same legal system finally there may be security concerns with allowing foreign access to some documents or systems thus for some services especially those where familiarity communication and non standardization contribute to quality the internet would not be expected to have a large impact on international trade to determine whether the internet has significantly affected international service provision in practice we estimate a general model of services trade across countries and examine whether the inclusion of data on internet penetration as measured by the number of internet hosts in a country is statistically significant overall our results offer evidence that the internet is related to growth in services trade after controlling for gdp and exchange rate movements we find that a 10 percent increase in internet penetration in a foreign country is associated with about a 1 7 percentage point increase in export growth and a 1 1 percentagepoint increase in import growth the results are robust to a number of alternative specifications

globalization outsourcing and wage inequality there is considerable debate over whether international trade has contributed to the declining economic fortunes of less skilled workers one issue that has become lost in the current discussion is how firms respond to import competition and how these responses in turn are transmitted to the labor market in previous work we have argued that outsourcing by which we mean the import of intermediate inputs by domestic firms has contributed to an increase in the relative demand for skilled labor in the united states if firms respond to import competition from low wage countries by moving non skill intensive activities abroad then trade will shift employment towards skilled workers within industries in this paper we extend our previous work by combining new import data from the revised nber trade database with disaggregated data on input purchases from the census of manufactures we construct industry by industry estimates of outsourcing for the period 1972 1990 and reexamine whether outsourcing has contributed to an increase in relative demand for skilled labor our main finding is that outsourcing can account for 31 51 of the increase in the relative demand for skilled labor that occurred in u s manufacturing industries during the 1980s compared to our previous estimate of 15 33 this abstract was borrowed from another version of this item

how many us jobs might be offshorable using detailed information on the nature of work done in over 800 us bureau of labor statistics occupational codes this paper ranks those occupations according to how easy hard it is to offshore the work either physically or electronically using this ranking it is estimated that somewhere between 22 and 29 of all us jobs are or will be potentially offshorable within a decade or two no estimate is made of how many jobs will actually be offshored since the rankings are subjective two alternatives are presented one is entirely objective the other is an independent subjective ranking in general they corroborate the rankings albeit not perfectly it is found that there is little or no correlation between an occupation s offshorability and the skill level of its workers as measured either by educational attainment or wages however it appears that controlling for education the most highly offshorable occupations were already paying significantly lower wages in 2004

social acceptance of renewable energy sources a review of contingent valuation applications abstract this paper presents a literature review addressing the public acceptance of renewable energy as a replacement for fossil fuels in electricity production this review was motivated by the global tendency for a substitution of conventional fuels by renewable energy sources res during the global financial crisis it studies research on the preferences and attitudes of local communities towards investments in renewable energy projects and their perception of the use of new energy technologies in their daily lives through various case studies worldwide an effort is made to identify the parameters that influence consumers energy behaviour together with their interest or lack thereof in the environmental impact of using fossil fuels to produce energy and their willingness to reduce it applications of contingent valuation are examined which are employed to analyse public attitudes towards the use of res for electricity production willingness to pay is observed to be correlated to socioeconomic characteristics including education interest in environmental issues and knowledge of res finally the profile of a typical green energy consumer and appropriate policy paths for the penetration of res into the energy market are outlined

choosing the right exchange old for new programs for durable goods with a rollover abstract by offering to trade in one unit of old product at a discounted price while selling new products exchange old for new eon programs have been considered efficient ways of expanding market for durable goods starting from the choice behavior of customers this paper studies optimal pricing and remanufacturing decisions for firms that adopt the eon program specifically considering a supply chain that consists of one manufacturer and one retailer we investigate two business models i in the manufacturer initiated scenario the manufacturer launches an eon program and owns all the old items that are returned he remanufactures all or a portion of the old items and sells them to a secondary market ii in the retailer initiated scenario any old items that are returned belong to the retailer she remanufactures the old items and sells them to the secondary market an in depth comparison between the optimal decisions in the two models is conducted in this paper we show it is possible that a firm may be even more profitable from being a free rider instead of offering an eon program by himself herself based on a centralized supply chain as a benchmark an exchange discount sharing contract is proposed to coordinate the supply chain and to improve the overall welfare of customers numerical experiments are conducted to show the profit impact for the supply chain members which uncover some interesting managerial insights for the proper adoption of the most efficient eon programs

winners and losers a micro level analysis of international outsourcing and wages our paper investigates the link between international outsourcing and wages utilizing a large household panel and combining it with industry level information on industries outsourcing activities from input output tables this approach avoids prob lems such as aggregation bias potential endogeneity bias and poor skill definitions that commonly hamper industry level studies we find that outsourcing has had a marked impact on wages applying two alternative skill classifications we find evidence that a 1 percentage point increase in outsourcing reduced the wage for workers in the lowest skill categories by up to 1 5 while it increased wages for high skilled workers by up to 2 6 this result is robust to a number of different specifications jel classification f16 j31 gagnants et perdants une analyse micro economique de la sous traitance internationale et des salaires ce memoire etudie le lien entre la sous traitance internationale et les salaires a l aide de donnees d un grand panel de menages qu on combine avec des donnees au niveau des industries sur les activites de sous traitance de celles qui en font obtenues des tableaux interindustriels cette approche evite les problemes qui habituellement polluent les etudes au niveau de l industrie biais d agregation biais d endogeneite potentielle mauvaises definitions des habiletes on decouvre que la sous traitance a un effet sur les salaires a l aide de differentes formes de classification des habiletes il appert qu un point de pourcentage d augmentation dans la sous traitance reduit les salaires des travailleurs dans les categories d habilete les plus basses de 1 5 alors qu il accroit les salaires de travailleurs specialises de 2 6 ce resultat est robuste et avere meme quand on utilise diverses specifications

durable good monopolies with rational expectations and replacement sales a monopoly producer of a durable good is examined under the previously uninvoked assumption that the good depreciates and hence that replacement sales must occur if a fixed stock of the good is to be maintained we find two ways in which the no depreciation result that the monopoly will always at least eventually produce a stock equal to that produced by a competitive market may not hold if the length of the trading period is nonzero the limiting stock produced by the firm will be lower than the competitive stock to ensure the profitability of future replacement sales if the firm is able to constrain its production capacity it may choose a constraint that always binds in the sense that it will be impossible for the firm to achieve a stock equal to the competitive stock

managing new and remanufactured products we study a firm that makes new products in the first period and uses returned cores to offer remanufactured products along with new products in future periods we introduce the monopoly environment in two period and multiperiod scenarios to identify thresholds in remanufacturing operations next we focus our attention on the duopoly environment where an independent operator io may intercept cores of products made by the original equipment manufacturer oem to sell remanufactured products in future periods we characterize the production quantities associated with self selection and explore the effect of various parameters in the nash equilibrium among other results we find that if remanufacturing is very profitable the original equipment manufacturer may forgo some of the first period margin by lowering the price and selling additional units to increase the number of cores available for remanufacturing in future periods further as the threat of competition increases the oem is more likely to completely utilize all available cores offering the remanufactured products at a lower price

valuation for renewable energy a comparative review abstract environmental cost benefit analysis is applied for the evaluation of renewable energy projects since some benefits and costs do not have monetary values economic valuation techniques are applied to estimate them this paper reviews the literature on the valuation evaluation of renewable energy resources and summarizes the methods used in them it discerns four main streams of valuation in renewable energy the first is economic welfare oriented and comprises stated and revealed preference methods the second is the financial option analysis with a financial background the third is emergy analysis which is mostly an ecological engineering based method with capable economic links and the fourth is again economic but not welfare based the paper discusses the main directions discerned in these studies and recognizes first that proper valuation takes place only in the first method while the other methods describe only evaluation procedures and second that there is a research gap that has yet to be filled in as compared to other areas of environmental resource and energy economics

offshoring and wage inequality using occupational licensing as a shifter of offshoring costs changes in information and communication technologies have increased the offshorability of tasks as routine tasks pol antras luis garicano and esteban rossi hansberg 2006 and lower offshoring cost tasks gene grossman and esteban rossi hansberg 2008 move abroad production processes become increasingly fragmented recent empirical papers e g mary amiti and shang jin wei 2005 runjuan liu and daniel trefler 2008 rosario crino forthcoming have aimed to illuminate the extent to which this is the case and the consequences of such changes a finding of this literature is that offshoring hurts disproportionately lower skill occupations and those occupations that are more tradable however this literature has been hampered by the difficulty of finding a good proxy for offshoring costs to measure the effect of offshoring on workers one would ideally want to increase offshorability of some tasks and not others and then compare the resulting changes in wages and employment in the occupations performing the tasks that are offshored with the ones that are not instead the literature has relied on proxies that are more or less directly linked to the skill content of the occupation and that as a result confound the effect of production technology and of offshoring cost there exist some partial exceptions such as j bradford jensen and lori g kletzer 2005 who argue that if a service is offshoring and wage inequality using occupational licensing as a shifter of offshoring costs

commodity bundling by single product monopolies consider two products that have independent demands in the sense that all individual buyers consider them neither substitutes nor complements then if the two products are priced separately the demand for either is independent of the price of the other in his classic analysis of block booking of feature films george stigler shows that it may be profitable for a monopoly seller of two such products to bundle them by requiring a buyer to take both in order to get either his work provides a rationale for tying arrangements that does not depend on technological or other dependencies among the products involved 2 adams and yellen extend the analysis of multiproduct monopoly with independent demands 3 they discuss two different bundling strategies pure bundling in which the seller only offers the products in fixed proportions and mixed bundling in which buyers may either buy the products separately or purchase a bundle with fixed proportions of each in this note i consider a single product monopoly and investigate the profit and welfare implications of bundling its product for some other

service offshoring and productivity evidence from the us the practice of sourcing service inputs from overseas suppliers has been growing in response to new technologies that have made it possible to trade in some business and computing services that were previously considered non tradable this paper estimates the effects of offshoring on productivity in us manufacturing industries between 1992 and 2000 it finds that service offshoring has a significant positive effect on productivity in the united states accounting for around 10 per cent of labour productivity growth during this period offshoring material inputs also have a positive effect on productivity but the magnitude is smaller accounting for approximately 5 per cent of productivity growth

household willingness to pay for green electricity in slovenia abstract this paper analyses the willingness to pay for electricity generated from renewable energy sources in slovenia the results confirm that age household income education and environmental awareness play the most important role in explaining household attitudes to green electricity programmes while the willingness to participate in green electricity programmes is influenced by education and environmental awareness the willingness to pay for green electricity predominantly depends on household income the results imply that green marketing should be accompanied by awareness raising campaigns and should target younger well educated and high income households the expressed median willingness to pay is found to exceed the current level of mandatory charges for green electricity nevertheless recent increases in final electricity prices might have already exhausted the capacity for additional voluntary contributions
