language and the earnings of immigrants several studies most of them employing straightforward regression analysis have concluded that immigrants proficiency in the language of their adopted country is correlated with their productivity as measured by earnings two weaknesses of these studies are potential unobserved heterogeneity which could result in over estimated effects if overall ability is linked with language acquisition and potential measurement error in the language proficiency measures which would probably result in under estimation of language effects the present study which uses panel data for a 10 year period in germany yields evidence that the latter bias tends to be much larger than the former implying that language proficiency is far more important than suggested by the existing literature

impacts of biodiesel production on croatian economy the aim of this paper is to assess the direct and indirect impacts on a national economy from biodiesel rapeseed methyl ester rme production using input output i o analysis biodiesel development in croatia is used as a case study for croatia as for many other countries in europe biodiesel is a new activity not included in the existing i o sectoral accounts for this reason the i o table has to be modified accordingly before being able to quantify the effect of an exogenous demand for biodiesel impacts in terms of output income and employment lead to the conclusion that biodiesel production could have significant positive net impact on the croatian economy despite the high level of subsidies for rapeseed growing

oppositional identities and employment for ethnic minorities evidence from england where a community or group is socially excluded from a dominant group some individuals of that group may identify with the dominant culture and others may reject that culture the aim of this article is to investigate this issue by empirically analysing the potential trade off for ethnic minorities between sticking to their own roots and labour market success we find that the social environment of individuals and attachments to culture of origin has a strong association with identity choice our results also suggest that those non whites who have preferences that accord with being oppositional do experience an employment penalty

gender differences in overeducation a test of the theory of differential overqualification there is little question that substantial labormarket differences exist between men and women among the most researched difference is the male female wage gap many different theories are used to explain why men earn more than women one possible reason is based on the limited geographic mobility of married women robert frank 1978 family mobility is a joint decision in which the needs of the husband and wife are balanced to maximize family welfare job motivated relocations are generally made to benefit the primary earner in the family this leads to a constrained job search for the secondary earner as he or she must search for a job in a limited geographic area since the husband is still the primary wage earner in many families the job search of the wife may suffer individuals who are tied to a certain area are labeled tied stayers while secondary earners who move for the benefit of the family are labeled tied movers jacob mincer 1978 the wages of a tied stayer or tied mover may not be substantially lower if the family lives in or moves to a large city if a large labor market has more vacancies the wife may locate a wage offer near the maximum she would find with a nationwide job search however being a tied stayer or tied mover can lower the wife s wage if the family lives in or moves to a small community a small labor market will reduce the likelihood of her finding a job that utilizes her skills as a result she may accept a job for which she is overqualified and thus earn a lower wage this hypothesized relationship between the likelihood of being overqualified and smsa size is termed differential overqualification frank 1978 and haim ofek and yesook merrill 1994 provide support for the theory of differential overqualification by finding that the malefemale wage gap is greater in smaller smsa s while the results are consistent with the existence of differential overqualification they may also result from other situations as well firms in small labor markets may use their monopsony power to keep wages down 2 local demand shocks are found to be a major source of wage variation both across and within local labor markets robert topel 1986 since large labor markets are generally more diversified a demand shock can have a substantial impact on immobile workers in small labor markets another reason for examining differential overqualification involves the assumption that there are more vacancies in large labor markets while there is little doubt that more vacancies exist in large labor markets there are also likely to be more people searching for jobs in large labor markets if the greater number of vacancies is offset by the larger number of searchers it is unclear whether women will be more likely to be overqualified in small labor markets instead of relying on wages to determine if differential overqualification exists we consider an explicit form of overqualification based on education

crisis era protectionism and the multilateral governance of trade an assessment this paper examines the multilateral governance of trade along with the prospects for its meaningful reform in the light of recent crisis era discrimination against the many types of cross border commerce prior episodes of protectionism provide a useful benchmark the findings are not optimistic the current set of multilateral rules is incomplete has weak incentives for compliance and can be readily circumvented only a far reaching revision of these rules could induce more restraint

when strong ties are strong networks and youth labour market entry the conditions under which young workers find their first real post graduation jobs are important for their future careers and insufficiently documented given their potential importance for young workers welfare to study these conditions and in particular the role played by social ties we use a swedish population wide linked employer employee data set of graduates from all levels of schooling that includes detailed information on family ties neighbourhoods schools class composition and parents and children s employers over a period covering years with both high and low unemployment together with measures of firm performance we find that strong social ties parents are an important determinant for where young workers find their first job the effects are larger if the graduate s position is weak low education bad grades during high unemployment years and when information on potential openings are likely to be scarce on the hiring side by contrast the effects are larger if the parent s position is strong long tenure high wage and if the parent s plant is more productive the youths appear to benefit from the use of strong social ties through faster access to jobs and by better labour market outcomes as measured a few years after entry in particular workers finding their entry jobs through strong social ties are considerably more likely to remain in this job while experiencing better wage growth than other entrants in the same plant firms also appear to benefit from these wage costs relative to comparable entrants starting at a lower base they also benefit on the parents side parents wage growth drops dramatically exactly at the entry of one of their children in the plant although this is a moment when firm profits tend to be growing indeed the firm side benefits appear large enough for at least small firms to increase job creation at the entry level in years when a child of one of their employees graduates

economic impacts of biofuels deployment in andalusia this paper aims to estimate the economic impacts of increasing the production capacity of the installed biofuel plants in andalusia southern spain a computable general equilibrium cge approach is used to calculate the changes in the economic sectors activity in employment as well as in gdp and other macroeconomic variables relevant to biofuel plants in andalusia under two distinct scenarios i based on an operating biodiesel plant with 90 ktoe year of installed capacity ii upgrading to 2174 ktoe by 2013 in compliance with the regional plan andaluz de sostenibilidad energetica pasener 2007 2013 results show that compliance with the pasener goal would increase the activity level of the economic sectors considered by 3 04 the total induced employment generated would reach 167 975 equivalent full time jobs lasting one year and the gdp would increase by 9 82

micro economic modelling of biofuel system in france to determine tax exemption policy under uncertainty abstract liquid biofuel support program launched in 1993 in france is implemented through tax exemptions to biofuels produced by agro industrial chains activity levels are fixed by decree and allocated by the government to the different chains based on earmarked budget increase voted in the parliament total quantity of biofuels will be increased by 50 in the horizon 2002 2003 a micro economic biofuel activity model containing a detailed agricultural sector component that is represented by 700 farms is used to estimate costs and surpluses generated by the activity at the national level as well as tax exemption levels furthermore monte carlo simulation has been used to search for efficient tax exemptions policies in an uncertain environment where biofuel profitability is significantly affected by petroleum price and soja cake prices results suggest that for the most efficient units both at the industry level large size biomass conversion units and at the agricultural sector level most productive farms unitary tax exemptions could be decreased by 10 20 for both biofuels ethyl ether and methyl ester with no risk for the viability of any existing chain

energy efficiency in india achievements challenges and legality abstract this paper explores the main legal center enforced commissions and acts that are aimed at improving the current energy deficit in the country with a specific emphasis on the need for research and a shift in the power market towards more sustainable technology the paper first examines the main aims of the governmental 5 year plans in the past ten years and then evaluates the merits and short comings of the existing technical framework that governs the electrical grid and generation systems in the country the paper also proposes inherent improvements with ground scale methods in developing a sound and competitive system for power distribution through consumer and employee involvement as well as changes in the investment arena that can substantially alter the market compatibility of renewably generated energy the paper indicates several key steps that the center and state governments have taken in order to revolutionise the feasibility of the electrical systems in the country finally the paper appraises and assesses the main amendments in the electrical industry legal literature and enforcement mechanisms that can effectuate rapid and systemic changes across the indian context

a market for renewable energy credits in the indian power sector abstract electricity generation from renewable energy sources in india has been promoted through a host of fiscal policies and preferential tariff for electricity produced from the same the fiscal policies include tax incentives and purchase of electricity generated through renewable energy sources the enactment of the electricity act 2003 the act has lent further support to renewable energy by stipulating purchase of a certain percentage of the power procurement by distribution utilities from renewable energy sources the renewable portfolio obligation as well as the feed in tariff for power procurement has been specified by a number of state electricity regulatory commissions sercs for the respective state under their jurisdiction a feed in tariff determined through a cost plus approach under a rate of return framework lacks incentive for cost minimisation and does not encourage optimal utilisation of renewable energy resources in the country such regulatory provisions differ across states the prevalent practice of fixing a renewable portfolio obligation along with cost based feed in tariffs disregards economic efficiency the paper proposes nationally tradable renewable energy credits scheme for achieving the targets set by the respective sercs as renewable portfolio obligation this would reduce the cost of compliance to a renewable portfolio obligation and would encourage efficient resource utilisation and investment in appropriate technologies the paper highlights its advantages and implementation issues this paper discusses regulatory developments for promotion of renewable energy in various indian states the paper also identifies a number of issues related to regulations concerning renewable portfolio obligation

power sector reform in india current issues and prospects power sector reforms in india were initiated at a juncture when the sector was plagued with commercial losses and burgeoning subsidy burden investment in the sector was not able to keep pace with growing demand for electricity this paper takes stock of pre reform situation in indian power sector and identifies key concerns that led to initiation of the process of reform the paper discusses major policy and regulatory changes undertaken since the early 1990s the paper also illustrates changes in the market structure as we move along the reform process we also discuss some of the major provisions of the recently enacted electricity act 2003 that aims to replace the prevailing acts which govern the functioning of the power sector in the country in this context we discuss two issues arising out of it namely open access and multi year tariff that we think would have a significant bearing on the performance of the sector in the near future the paper also evaluates the reform process in the light of some of the regulatory changes undertaken finally the paper briefly discusses the issues involved in introduction of competition in the power sector primarily through development of a market for bulk power

an empirical test of the infant industry argument the basic infant industry argument maintains that the cost of a new activity is initially high it does not pay any individual to enter an infant industry at free trade prices if developed the industry will permit a reasonable return on initial losses and a temporary period of protection is required this paper has attempted two things to develop an empirical test for the validity of the infant industry argument and to use that test on turkish data the test is simple and straightforward input per unit of output must fall more rapidly in more protected industries if there is to be any rationale for infant industry protection in the turkish case there was no such tendency over the period covered the fact that protected turkish industries did not experience rapid increases in output per unit of input is sufficient to prove that protection was not warranted it does not however prove that there were no infant industries the trade regime might have provided the wrong incentives and under an alternative structure output per unit of input might have grown more rapidly in some or possibly all turkish industries in conclusion protection did not elicit the sort of growth in output per unit on which infant industry proponents base their claim for protection

regulatory performance analysis case study britain s electricity industry the success or failure of the privatisation and liberalisation of electricity supply industries has more often been judged in terms of process than of outcomes in this paper in contrast this performance is assessed in terms of the performance of its associated system of regulatory governance taking the uk s electricity supply industry between 1989 and 2000 as case study initially a vertical cross section of the regulation system gives a finding matrix for the various stakeholders involved and identifying winners and losers from the standpoint of funding flows next a horizontal cross section provides the environmental distributive allocative dynamic and productive efficiencies grid for this system the survey shows that the performance of the british esi regulation system produced benefits although not for all stakeholders and not as fairly as possible the chosen path did not seem sustainable and failed to respect intergenerational transfers as a way of fostering sustainability and equity it was unable to underpin simultaneous improvements in efficiencies over time while redistributing industry s funding flows among the players in a regressive manner

persistent trade effects of large exchange rate shocks this paper presents a theoretical basis for the argument that large exchange rate shocks such as the 1980s dollar cycle may have persistent effects on trade flows and the equilibrium exchange rate itself we begin with a partial equilibrium model in which large exchange rate fluctuations lead to entry or exit decisions that are not reversed when the currency returns to its previous level then we develop a simple model of the feedback from hysteresis in trade to the exchange rate itself here we see that a large capital inflow which leads to an initial appreciation can result in a persistent reduction in the exchange rate consistent with trade balance

electricity privatization the case of india abstract privatization is resorted to by developing country governments mainly to augment resource mobilization either on their own initiative or under the dictat of the world bank and less as a recipe for efficiency improvement the present paper discusses the electricity privatization in india as a case study and outlines the practical problems faced when the theoretical issues of privatization come up against the messiness of the real world such as high cost of private power compared to the low cost of public power and the goal conflicts of public and private utilities it suggests a different model to make privatization feasible

local regional and national level of the socioeconomic impacts of a bio oil production system a case in lieksa finland abstract the aim of this paper is to assess the direct and indirect socioeconomic impacts on a local regional and national economy from forest biomass based bio oil production using input output i o analysis we also analysed the importance of a bio oil factory on the development of the local economy and determined the type of impacts bio oil production has on population and employment development and on the public municipal economy our study area is located in a resource periphery far from growing regions and suffers from development problems and stagnating development trends in terms of employment and income bio oil production could have a significant positive net impact on the local economy despite leakages to regional and national economies the impacts of bio oil production could enhance the future development prospects for the resource periphery according to positive changes in the net migration and by slowing population losses

power sector reform in south asia why slow and limited so far although south asian developing countries had initiated some form of electric power sector reform in the 1990s often under external lending agency pressures not much progress has been made so far and there is hardly any noteworthy example of a successful reform in the region this paper provides a brief review of power sector reform efforts in five south asian countries and uses an institutional economics framework to identify the factors shaping the success of power sector reforms four factors namely instability of rule makers poor overall acceptance slow adaptation and poor transition management are identified and their effect on the reform process of south asia are analysed the paper finds that political instability has affected the power sector reform of the region making hard decisions difficult to take slow progress of reform has also affected the sector viability as signs of adverse effects on the power sector investment and performance are already visible

meeting strangers and friends of friends how random are social networks we present a dynamic model of network formation where nodes find other nodes with whom to form links in two ways some are found uniformly at random while others are found by searching locally through the current structure of the network e g meeting friends of friends this combination of meeting processes results in a spectrum of features exhibited by large social networks including the presence of more high and low degree nodes than when links are formed independently at random having low distances between nodes in the network and having high clustering of links on a local level we fit the model to data from six networks and impute the relative ratio of random to network based meetings in link formation which turns out to vary dramatically across applications we show that as the random network based meeting ratio varies the resulting degree distributions can be ordered in the sense of stochastic dominance which allows us to infer how the formation process affects average utility in the network

density social networks and job search methods theory and application to egypt we first develop a theoretical model in which individuals are embedded within a network of social relationships we show that conditional on being employed the probability to find a job through social networks relative to other search methods increases and is concave with the size of the network the effects are stronger for the uneducated there is however a critical size of the network above which this probability decreases we then test empirically these theoretical findings for egypt using the 1998 labor market survey the empirical evidence supports the predictions of our theoretical model

effects of a carbon price in the u s on economic sectors resource use and emissions an input output approach abstract despite differences in their implementation most carbon policies aim to have similar outcomes effectively raising the price of carbon intensive products relative to non carbon intensive products while it is possible to predict the simple broad scale economic impacts of raising the price of carbon intensive products the demand for non carbon intensive products will increase understanding the economic and environmental impacts of carbon policies throughout the life cycle of both types of products is more difficult using the example of a carbon tax this study proposes a methodology that integrates short term policy induced consumer demand changes into the input output framework to analyze the environmental and economic repercussions of a policy environmental repercussions include the direct and the indirect impacts on emissions materials flow in the economy and the reliance on various ecosystem goods and services the approach combines economic data with data about physical flow of fossil fuels between sectors consumption of natural resources and emissions from each sector it applies several input output modeling equations sequentially and uses various levels of aggregation disaggregation it is illustrated with the data for the 2002 u s economy and physical flows the framework provides insight into the short term complex interactions between carbon price and its economic and environmental effects

the development of renewable energy power in india which policies have been effective abstract the international energy agency has identified the development of renewable energy sources as a key element to mitigate climate change at the same time it has projected india to be the second largest contributor to the increase in global energy demand to 2035 india hence faces a significant challenge to ensure its energy security by diversifying its power generation mix in the wake of the creation of a green climate fund in cancun this paper studies empirically the effect of the introduction of the electricity act 2003 and the tariff policy 2006 as well as the implementation of feed in tariffs and minimum quotas on clean electricity sourcing on the development of grid connected renewable energy power in nine indian states over the period 2001 2009 results suggest that the passing of the tariff policy 2006 state level policies quantity based instruments and a greater participation of the private sector have played a key role in promoting the development of installed capacity from renewable energy power in the nine states of the sample

impact of reform and privatization on consumers a case study of power sector reform in orissa india abstract orissa is the first state in india to have undergone reform in the power sector with the government withdrawing its control the model of this reform is known as the wb orissa model the goal of this paper is to examine the impact of this reform on consumers of electricity which has been measured using multiple regression models the variables represent the parameters that consumers are most interested in and the regression coefficients represent the weights of the corresponding variables the data were collected using a survey methodology the impact of reform was found to be mixed some groups of consumers saw benefits while others felt a negative impact a focus group study was conducted to identify the variables of interest to consumers of electricity the model was used to estimate consumer benefit and was validated using primary data and structural equation modeling the study revealed beneficial aspects of reform and areas with no benefits

social contacts and occupational choice social contacts help workers to find jobs but those jobs need not be in the occupations where workers are most productive hence social contacts can generate mismatch between a worker s occupational choice and his comparative productive advantage thus economies with dense social networks can exhibit apparently low labor force quality and as a result low returns to firms investment and depressed aggregate productivity we employ us and european data for the 1990 s to test the key prediction that social contacts distort workers occupational choices in a direction that reduces their apparent productivity we find that the use of social contacts helps find jobs one to two months sooner but leads to individual wage discounts of 5 to 7 and produces negative externalities on aggregate productivity

promoting policy reforms the twilight of conditionality abstract for the past 15 years the world bank often in cooperation with the international monetary fund and sometimes also with bilateral donors has tried to encourage policy reforms through conditions attached to structural or sector adjustment loans in the 1990s however such loans are a rapidly dwindling portion of the bank s disbursements this article examines major reasons for this shift including increased flows of private capital democratization the changing nature of the reform agenda itself and growing bank emphasis on ownership reduced direct conditionality is likely to be replaced in part by growing selectivity the results may well be constructive but will not ease tensions in the aid relationship

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

the regional economic impacts of biofuels a review of multisectoral modelling techniques and evaluation of applications allan g j the regional economic impacts of biofuels a review of multisectoral modelling techniques and evaluation of applications regional studies the regional economic impact of biofuel production depends upon a number of interrelated factors the specific biofuels feedstock and production technology employed the sector s embeddedness in the rest of the economy through its demand for local resources and the extent to which new activity is created these issues can be analysed using multisectoral economic models some studies use input output io and social accounting matrix sam modelling frameworks whilst a nascent computable general equilibrium cge literature has begun to examine the regional impact of biofuel development this paper reviews compares and evaluates these approaches for modelling the regional economic impacts of biofuels

electricity privatization revisited a commentary on the case for new initiatives in india abstract normally privatization is resorted to by different economies for different reasons resource mobilization introducing efficiency by promoting competition and for achieving commercial orientation often these are assumed to be independent objectives the indian experience is showing that they are quite interdependent and unless all the three objectives are tackled simultaneously privatization will not succeed specifically the poor financial performance of the state electricity boards and their lack of commercial orientation is applying a brake on investment in the power sector by foreign ipps similarly the government s approach to privatization without promoting competition through the so called memorandum of understanding is leading to high cost solutions and acrimonious public debates demanding transparency in decision making and review of those already made

job search methods and their success a comparison of immigrants and natives in the uk a major issue in the immigration debate concerns whether immigrants take jobs away from natives in this article we present new evidence on the job search methods used by immigrants and their relative success in gaining employment in the uk we find that 1 immigrant job search is less successful than that of natives 2 immigrants are as likely to gain employment through informal methods as via verifiable routes 3 the probability of success increases with years since migration the finding that immigrants do not effectively compete for jobs may help explain why immigration has little impact on native employment

status of electricity act 2003 a systematic review of literature abstract the electricity act 2003 was a landmark act which promised to remove the maladies which afflict the indian power sector and that too at a time when the sector was ridden with problems with concepts such as open access multiple distribution licensees wheeling of electricity etc the said act intended to encourage competition which in turn was meant bring a paradigm shift in the sector the paper undertakes a systematic literature review to find the status of review of the promising act more than a decade has passed since its enactment and amendments are due with the legislative body of india but none of the literature reviewed gives a comprehensive view encompassing all the objectives of the act moreover these documents study either the probable impact or the impact on a particular segment only it has important implications for the power sector which highlights a significant gap in literature and provides a basis on which future research can be built upon

do friends and relatives really help in getting a good job informal contacts are extensively used by both firms and workers to find jobs and fill vacancies the common wisdom in the economic literature is that jobs created through this channel are of better quality and pay higher wages than jobs created through formal methods this paper explores the empirical evidence for european countries using the european community household panel echp and discovers a large cross country as well as cross industry variation in the wage differentials between jobs found through informal and formal methods across countries and industries wage premiums and wage penalties to finding jobs through personal contacts are equally frequent this paper argues that such variation can be explained by looking at firms recruitment strategies in labour markets where employers invest largely in formal recruitment activities matches created through this channel are likely to be of average better quality than those created through informal networks a simple theoretical model is used to show that employers invest more in recruitment for high productivity jobs and for positions that require considerable training the empirical predictions of the theory are successfully tested using industry level data on recruitment costs

power sector reform in developing countries mismatched agendas power sector reform is rapidly spreading across all corners of the developing world at an alarmingly rapid pace while the rationales for reform seem to have gained acceptance among the stakeholders the reform model and process are contested this paper examines the impacts of reform using the promised outcomes as a basis for analysis the ability of reform to meet the developmental challenges facing the reformers is explored it concludes that reform has had some achievements if conventional performance indicators are used but also questions the validity of some of these indicators reform has however not fulfilled many of its goals and the prevailing recipes are likely to leave developing countries socially and economically worse off than in the pre reform period progressive government intervention is needed to shift reform process towards a more responsible development path

the effect of regulatory governance on efficiency of thermal power generation in india a stochastic frontier analysis abstract this paper investigates the impact of institutional quality typified as regulatory governance on the performance of thermal power plants in india the indian power sector was reformed in the early 1990s however reforms are effective only as much as the regulators are committed in ensuring that they are implemented we hypothesize that higher the quality of regulation in a federal indian state higher is the efficiency of electric generation utilities a translog stochastic frontier model is estimated using index of state level independent regulation as one of the determinants of inefficiency the dataset comprises a panel of 77 coal based thermal power plants during the reform period covering over 70 of installed electricity generation capacity the mean technical efficiency of 76 7 indicates there is wide scope for efficiency improvement in the sector results are robust to various model specifications and show that state level regulators have positively impacted plant performance technical efficiency is sensitive to both unbundling of state utilities and regulatory experience the policy implication is that further reforms which empower independent regulators will have far reaching impacts on power sector performance

tariffs and growth in the late 19th century the paper estimates the correlation between tariffs and economic growth in the late 19th century in the context of three types of growth equation unconditional convergence equations conditional convergence equations and factor accumulation models it does so for a panel of ten countries between 1875 and 1914 tariffs were positively correlated with growth in these countries during this period economic theory is ambiguous as regards the relationship between trade policy and growth the growth literature of the past decade has produced an impressive array of models in which protection can either increase or reduce long run growth rates grossman and helpman 1991 rivera batiz and romer 1991 stokey 1991 young 1991 such theoretical ambiguity invites empirical research while new growth theory is ambiguous on the subject the new empirical growth literature has produced a consensus that free trade is positively associated with growth based on evidence from the late 20th century but see rodrlguez and rodrik 1999 for a sceptical review of the literature the clear

the institutions and governance of economic development and reform why are the ambitions of economic development practitioners and reformers so often disappointed one answer is that development policymakers and reformers are congenital optimists another answer is that good plans are regularly defeated by those who occupy strategic positions an intermediate answer is that institutions are important yet are persistently neglected in the planning process the article takes a bottom up microanalytical approach to economic development and reform it examines the governance of contract investment and private ordering through the lens of transaction cost economizing and it assesses the efficacy of the de facto as against the de jure institutional environment with respect to credible commitments in effect institutional economists are cast in the role of archaeologists of economic reform and development with the task of unpacking the lessons of the past to inform choices and programs for the future

regulation institutions and commitment in telecommunications a comparative analysis of five country studies within any system of utility regulation there is a tension between the ability to commit to a stable set of rules and the ability to respond flexibly to changing circumstances countries differ in their institutional endowments and hence in the ways in which they can resolve this tension a first group of countries can design regulatory systems that afford the regulator substantial formal discretion to respond to changing circumstances and can use process to restrain arbitrary action a second group of countries can restrain arbitrary action only by calling on specific substantive rules and may have to sacrifice some flexibility to achieve credible commitment a third group may lack the domestic institutions to put in place a credible and workable regulatory system of any kind

the impact of surplus schooling on earnings some additional findings this paper examines the impact of overeducation or surplus schooling on earnings overeducated workers are defined as those with educational attainments substantially above the mean for their specific occupations two models are estimated using data from the 1980 census though our models data and measure of overeducation are different from those used by rumberger 1987 our results are similar our results show that overeducated workers often earn less than their adequately educated and undereducated counterparts

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

political pricing of electricity can it go with universal service provision abstract political parties in india are known to use electricity prices as a tool to secure a win in the democratic election process this article examines the setting of electricity prices from a political economy perspective citizens differ in their willingness to pay for electricity and the consumer surplus and electoral uncertainty seem to influence their choices while exercising their franchise to win political parties must receive a majority of votes and a party in power may try to achieve this by choosing to ignore a consumer group either by charging a price higher than their willingness to pay or by choosing to satisfy them by charging a lower price two theoretical models are proposed the first model computes the possible prices when common perfectly correlated electoral shocks are anticipated while the second model computes the possible prices for independent and identically distributed electoral shocks we test these models with available data on willingness to pay and electricity price for agricultural domestic and industrial consumers in an indian state by generating prices that would be charged to each of these types of consumers to maximize the chances of re election actual prices seem to confirm the second model more than the first

russia s commercial policy 2008 11 modernization crisis and the wto accession this paper examines the commercial policy of russia during 2008 11 a time of global financial crisis which coincided with an announced russian modernization programme in 2008 russia introduced a development strategy to limit its dependence on natural resources however the government relied heavily on this income for the planned modernization programme the falling price of oil in 2008 9 led to a tightened government budget constraint this situation induced russia towards wider use of more traditional instruments of trade policy such as tariff policy as well as an import substitution strategy the creation of the customs union and a pause in the wto accession process russia has been found by the global trade alert gta initiative to be one of the main users of protectionist policies since november 2008 with the oil price recovery from september 2010 russia had been back in the wto accession process on revised terms and conditions the wto ministerial conference in geneva approved the accession package of the russian federation on 16 december 2011 copyright 2012 oxford university press

current status and analysis of renewable promotional policies in indian restructured power sector a review restructuring has changed the traditional mission and mandates of power utilities in complex ways and had large impacts on environmental social and political conditions for any particular country at the same time new regulatory approaches are being found for reducing environmental impacts in restructured power sectors india has a vast supply of renewable energy resources and it has one of the largest programs in the world for deploying renewable energy based products and systems so this paper attempts to review the various policies and measures undertaken by indian government for promotion of renewable energy the aim of this paper is also to review the current policy mechanisms especially investment or generation based price driven and capacity driven mechanisms ranging from investment incentives for the development of renewable energy projects feed in tariffs production tax incentives tradable green certificates and their effects upon the prospects of encouraging as well as expanding the development of renewable energy in indian restructured power sector this will make renewable more attractive in the indian future electricity market

job search and network composition implications of the strength of weak ties hypothesis workers find jobs through personal contacts weak and strong ties and formal sources alternative formulations of the strength of weak ties hypothesis suggest 1 weak ties relay job offers more frequently than strong ties or 2 weak tie offers are drawn from a better distribution a formal model shows that both formulations imply a correlation between network composition and a job seeker s minimum acceptable wage however the use of a weak tie is never associated with higher expected wages under the firstformulation and is only sometimes associated with higher expected wages under the secondformulation these results suggest that researchers shouldfocus on job seekers network structures

the impacts of the german biofuel quota on sectoral domestic production and imports of the german economy abstract this study analyses the impacts of the german biofuel quota on sectoral domestic production and imports of the german economy the effects are calculated as net effects i e accounting for the direct and indirect effects of both the additional demand for biofuels and the reduced demand for fossil fuels the analysis uses an input output model and information on quantities production processes import quotas etc to calculate the impacts for the agricultural sector which is obviously of high relevance for biofuel production two cases are differentiated first and in line with classical input output assumptions we propose that agricultural production is not constrained by the availability of agricultural land thus biofuel production is basically added to other agricultural outputs in the second case agricultural land is considered a limiting factor for production as a consequence biofuel production substitutes other agricultural outputs the results indicate a clear increase of domestic production and a decline of net imports in the first case in the second case gains in domestic production are smaller and net imports are in contrast to the first case increasing

effects of regulatory reforms in the electricity supply industry on electricity prices in developing countries electric power sector reforms in the electricity supply industry have had an impact on industrial and household prices in developing countries in latin america the former soviet union and eastern europe using original panel data for 83 countries during the period from 1985 to 2002 we examine how each policy instrument of the reform measures influenced electricity prices for countries in the above regions we found that variables such as entry of independent power producers ipp unbundling of generation and transmission establishment of a regulatory agency and the introduction of a wholesale spot market have had a variety of impacts on electricity prices some of which were not always consistent with expected results the research findings suggest that neither unbundling nor introduction of a wholesale pool market on their own necessarily reduces the electric power price in fact contrary to expectations there was a tendency for the price to rise however coexistent with an independent regulator unbundling may work to reduce electricity prices privatization and the introduction of foreign ipp and retail competition lower electricity prices in some regions but not all

overeducation undereducation and the british labour market this paper addresses the issue of overeducation and undereducation using for the first time a british dataset which contains explicit information on the level of required education to enter a job across the generality of occupations three key issues within the overeducation literature are addressed first what determines the existence of over and undereducation and to what extent are over and undereducation substitutes for experience tenure and training second to what extent are over and undereducation temporary or permanent phenomena third what are the returns to over and undereducation and do certain stylized facts discovered for the us and a number of european countries hold for britain

infant industry protection in the steel rail industry abstract this paper examines a particular instance of infant industry protection the case of the u s steel rail industry it analyzes the joint roles of learning by doing changing resource endowments and tariff protection in the emergence of this industry making use of estimated demand and cost parameters the paper simulates what would have happened to prices production and welfare under free trade i calculate that despite strong learning effects the steel rail tariff hurt rail users in both the short and long runs the tariff s overall effect on welfare was positive but fairly small

networks in the modern economy mexican migrants in the u s labor market this paper attempts to identify job networks among mexican migrants in the u s labor market the empirical analysis uses data on migration patterns and labor market outcomes based on a sample of individuals belonging to multiple origin communities in mexico over a long period of time each community s network is measured by the proportion of the sampled individuals who are located at the destination the united states in any year we verify that the same individual is more likely to be employed and to hold a higher paying nonagricultural job when his network is exogenously larger by including individual fixed effects in the employment and occupation regressions and by using rainfall in the origin community as an instrument for the size of the network at the destination

efficiency assessment and benchmarking of thermal power plants in india abstract per capita consumption 1 of electricity in india is many folds lesser than canada usa australia japan chaina and world average even though total energy shortage 2 and peaking shortage 3 were recorded as 11 2 and 11 85 respectively in 2008 09 reflecting non availability of sufficient supply of electricity performance improvement of very small amount can lead to large contribution in financial terms which can be utilized for capacity addition to reduce demand supply gap coal fired thermal power plants are main sources of electricity in india in this paper relative technical efficiency of 60 coal fired power plants has been evaluated and compared using ccr and bcc models of data envelopment analysis target benchmark of input variables has also been evaluated performance comparison includes small versus medium versus large power plants and also state owned versus central owned versus private owned result indicates poor performance of few power plants due to over use of input resources finding reveals that efficiency of small power plants is lower in comparison to medium and large category and also performance of state owned power plants is comparatively lower than central and privately owned study also suggests different measures to improve technical efficiency of the plants

some contacts are more equal than others informal networks job tenure and wages the explanation typically given for longer tenure among workers who use informal contacts to find jobs is that relatives and friends reduce uncertainty about the quality of the match between worker and employer an alternative explanation is that workers rely on informal information sources as a last resort such workers remain at their current jobs mainly because they have few alternative choices rather than because of better match quality this article shows that the two different explanations are simultaneously valid for different types of contacts and can account for differences in the wage effects of job contacts

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

power sector reform in orissa an ex post analysis of the causal factors abstract from the early 1990s dramatic changes have been taking place in the structure of electricity supply industry esi worldwide the primary reasons for electricity sector reform has however been different for industrialised and developing countries the objective of this paper is to study and identify various factors leading to power sector reform in developing countries the restructuring of orissa state electricity board in india was used as a case study in identifying the various factors the factors that result in implementation of restructuring are a contextual factors they are the primary drivers for initiating reform the performance of the utility and the conditionalities of the lending agencies are contextual factors b trigger factor it is the determining factor that creates a compelling necessity to undergo restructuring the inability of the government to continue to support the utility acts as the trigger factor c facilitating factors they act as facilitators for initiating reform support of the government absence of a powerful lobby and the support of the top management are facilitating factors

matchmaker matchmaker the effect of old boy networks on job match quality earnings and tenure firms often view job applicant referrals from current employees as more informative than direct applications or referrals through formal labor market intermediaries such as placement firms we argue that old boy networks reduce employers uncertainty about worker productivity using jovanovic s job matching model we show that workers hired through the old boy network should 1 earn higher initial salaries 2 experience lower subsequent wage growth on the job and 3 stay on the job longer than otherwise comparable workers hired from outside the network we find considerable support for this theory using data from the 1972 survey of natural and social scientists and engineers
