simultaneous attainment of energy goals by means of green certificates and emission permits abstract we discuss the analytical effects of introducing emission permits and green certificates and the corresponding quotas as regulatory mechanisms to respectively reduce emissions from electricity production and ensure a certain deployment of renewable energy the different case studies in this paper show that both instruments can be used in order to reach an emission goal or a goal of renewable energy however the combination of these instruments and the way they are used is shown to be important for the price faced by consumers it is shown that the effect on the consumer price is not an unambiguous increase with the introduction of a green quota there is a choice between quotas leading to a lower consumer price and quotas leading to a higher consumer price as a result of this it is shown that it is always optimal to reach a renewable energy deployment goal by the use of green certificates however to reach an emission goal it is sometimes most favourable with respect to consumer prices to use green certificates and sometimes to use emission permits

ethnicity neighborhoods and human capital externalities the socioeconomic performance of today s workers depends not only on parental skills but also on the average skills of the ethnic group in the parents generation or ethnic capital this paper investigates the link between the ethnic externality and ethnic neighborhoods the evidence indicates that residential segregation and the external effect of ethnicity are linked partly because ethnic capital summarizes the socioeconomic background of the neighborhood where the children were raised ethnicity has an external effect even among persons who grow up in the same neighborhood when children are exposed frequently to persons who share the same ethnic background copyright 1995 by american economic association

the innovation impact of the eu emission trading system findings of company case studies in the german power sector abstract this paper provides a detailed analysis of how the european emission trading system eu ets as the core climate policy instrument of the european union has impacted innovation towards this end we investigate the impact of the eu ets on research development and demonstration rd d adoption and organizational change in doing so we pay particular attention to the relative influences of context factors policy mix market factors and public acceptance and firm characteristics value chain position technology portfolio size and vision empirically our qualitative analysis is based on multiple case studies with 19 power generators technology providers and project developers in the german power sector which were conducted in 2008 09 we find that the innovation impact of the eu ets has remained limited so far because of the scheme s initial lack of stringency and predictability and the relatively greater importance of context factors additionally the impact varies significantly across technologies firms and innovation dimensions and is most pronounced for rd d on carbon capture technologies and organizational changes our analysis suggests that the eu ets on its own may not provide sufficient incentives for fundamental changes in corporate innovation activities at a level which ensures political long term targets can be achieved

origins and development of the eu ets the successful creation of the european union emissions trading scheme eu ets was not inevitable countries such as canada and japan which might be thought to have a less complex and more cohesive cultural and institutional context failed to do so europe succeeded for a number of reasons with a single market for the economy the logic of a single market for environment is inexorable the european commission which had failed in its earlier efforts to introduce a carbon energy tax made the case for trading with great skill and persistence on the basis of qualified majority voting which meant no country had a veto the uk and denmark initiated their own national schemes and there was a serious risk of balkanising the market with up to 27 different schemes with the losses of scale and scope this would entail meeting the union s kyoto commitments required a substantive pan european response and eu ets was the most credible and effective way of doing so the european parliament and environmental non governmental organisations played a constructive role pushing for more auctioning of allowances and less of them allocated centrally free allocation managed by member states ms was a necessary condition to achieve the support needed so they failed to achieve these objectives in the initial phase but they characterize the commission s proposals post 2012

productivity gains from geographic concentration of human capital evidence from the cities abstract based on recent theoretical developments the argument is made that the average level of human capital is a local public good cities with higher average levels of human capital should therefore have higher wages and higher land rents after conditioning on the characteristics of individual workers and dwellings this prediction is supported by data for standard metropolitan statistical areas smsas in the united states where the smsa average levels of formal education and work experience are used as proxies for the average level of human capital the alternative explanations of omitted smsa variables and self selection are evaluated an estimate of the effect of an additional year of average education on total factor productivity is computed

moving out but not up economic outcomes in the great migration the migration of millions of southerners out of the south between 1910 and 1970 is largely attributed to economic and social push factors in the south combined with pull factors in other regions o

economic aspects of anti dumping policies the common sense view of dumping is that it is an unfair trading practice against which nations should legitimately be able to introduce countervailing measures no government can be expected to stand by whilst its markets are flooded by foreign imports whose prices are kept artificially low in relation to the price of the product on its own tariff protected domestic market it is this type of unfair trading advantage which anti dumping legislation is designed to combat stanbrook 1980 in line with this view article vi of the general agreement on tariffs and trade gatt permits importing countries to impose anti dumping duties in appropriate circumstances normal gatt obligations notwithstanding although it is interesting to note that the practice of dumping is not in itself contrary to any of the gatt rules as a result individual nations and trading blocks have developed extensive anti dumping laws and regulations that are broadly consistent with article vi and with the associated gatt anti dumping code which interprets the provisions of article vi and elaborates rules for their application

eu climate policy up to 2020 an economic impact assessment in its fight against climate change the eu is committed to reducing its overall greenhouse gas emissions to at least 20 below 1990 levels by 2020 to meet this commitment the eu builds on segmented market regulation with an eu wide cap and trade system for emissions from energy intensive installations ets sectors and additional measures by each eu member state covering emission sources outside the cap and trade system the non ets sector furthermore the eu has launched additional policy measures such as renewable energy subsidies in order to promote compliance with the climate policy target basic economic reasoning suggests that emission market segmentation and overlapping regulation can create substantial excess costs if we focus only on the climate policy target in this paper we evaluate the economic impacts of eu climate policy based on numerical simulations with a computable general equilibrium model of international trade and energy use our results highlight the importance of initial market distortions and imperfections as well as alternative baseline projections for the appropriate assessment of eu compliance cost

economies of scale and utilization in the swiss electric power distribution industry economies of scale and utilization in the swiss electricity distribution industry are analysed a translog variable cost function was estimated using panel data for a sample of 39 municipal utilities over the period 1988 1991 economies of both scale and utilization appear to exist in the distribution of electricity both for small medium and large sized utilities thus the empirical evidence suggests sub additivity of the cost function over the relevant range of output for the swiss electricity distribution utilities a necessary condition for a natural monopoly to exist

migration with endogenous moving costs we study a dynamic model of labor migration in which moving costs decrease with the number of migrants already settled in the destination this assumption is supported by sociological studies of migrant networks with endogenous moving costs migration occurs gradually over time once it starts it develops momentum and migratory flows may increase even as wage differentials narrow in addition migration tends to follow geographical channels and low moving cost individuals migrate first these patterns are consistent with historical evidence from the great black migration of 1915 1960 in the united states much of which cannot be reconciled with existing migration models excerpt

the pursuit of opportunity explaining selective black migration abstract this paper examines the destination choices of black migrants during the great migration as previous research has shown educated blacks were more likely to relocate to the north in the pre world war ii era this analysis shows that this tendency can be attributed to the better educated migrants ability to finance transportation costs greater responsiveness to intercity wage differentials and stronger distaste for southern disamenities after 1940 the destination choice gap closed largely because migrant responses to wage differentials and valuation of southern disamenities changed these changes are observed both in the population at large and within birth year cohorts

britain s newest import america s regulatory experience the first of these generation is a level into which competition can be injected but transmission and distribution are closer to natural monopolies the operators of the transmission grid will if separated from the other sectors have substantial monopoly power even the firmest believers in the ubiquity of contestable markets would be hard pressed to argue that potential entry effectively limits the grid s monopoly power

efficiency and regulation of the slovenian electricity distribution companies abstract the slovenian energy law adopted in 1999 has opened the internal market to competition up to 64 of the final consumption the opening of the internal market to foreign competition is envisaged for 2003 with regard to the methodology of price regulation the energy law introduces the price cap regulation which aims to give firms incentive for cost reduction to provide information for effective price regulation we estimated a cost frontier function on a sample of slovenian electricity distribution utilities over the 1991 2000 period the estimated efficient frontier could be used by slovenian regulatory agency as a benchmark to regulate network access prices our results show that slovenian distribution companies are cost inefficient we have also proved the presence of increasing returns to scale with most utilities not achieving the minimum efficient scale thus the slovenian regulatory authority should consider how to induce mergers of small electricity distribution utilities into larger units

residential segregation and socioeconomic outcomes when did ghettos go bad abstract cutler and glaeser 1997 show that urban residential segregation has a strong adverse effect on labor market and social outcomes of young african americans relative to whites we show that this effect is a fairly recent historical phenomenon there is little evidence of such an effect from 1940 to 1970 rather it emerged between 1970 and 1980 and it grew stronger during the 1980s

emission abatement untangling the impacts of the eu ets and the economic crisis abstract in this study we use historical emission data from installations under the european union emissions trading system eu ets to evaluate the impact of this policy on greenhouse gas emissions during the first two trading phases 2005 2012 as such the analysis seeks to disentangle two causes of emission abatement that attributable to the eu ets and that attributable to the economic crisis that hit the eu in 2008 09 to do so we use a dynamic panel data approach our results suggest that by far the biggest share of abatement was attributable to the effects of the economic crisis this finding has serious implications for future policy adjustments affecting core elements of the eu ets including the distribution of eu emission allowances

abatement and allocation in the pilot phase of the eu ets we use historical industrial emissions data to assess the level of abatement and over allocation that took place across european countries during the pilot phase 2005 2007 of the european union emission trading scheme using a dynamic panel data model we estimate the counter factual business as usual emissions scenario for eu member states comparing this baseline to allocated and verified emissions we find that both over allocation and abatement occurred along with under allocation and emissions inflation over the three trading years of the pilot phase we find over allocation of approximately 280 million euas and total abatement of 247 mt co2 however we calculate that emissions inflation of approximately 73 mt co2 also occurred possibly due to uncertainty about future policy design features

decoupling the eu ets from subsidized renewables and other demand side effects lessons from the impact of the eu ets on co2 emissions in the german electricity sector abstract this paper analyzes the impact of the eu ets on co2 reduction in the german electricity sector we find an ets induced emission abatement which is not exceeding 6 of total emissions with a maximum already in 2010 thereafter the ets has not induced additional reductions this outcome corresponds to the recent debate about sub optimal performance of the eu ets caused by excessive allowances following up on this we develop a unilateral flexible cap to eliminate demand side effects which lead to excessive allowances the unilateral flexible cap is based on emission intensities using the works of newell and pizer 2008 sue wing et al 2009 we prove that an intensity based emission cap is advantageous in the german electricity sector when compared to an absolute cap an ex post analysis shows that the amount of excessive allowances resulting from the economic crisis during the second trading period could have been significantly lowered with a unilateral flexible cap this approach also decouples the eu ets from a simultaneous promotion of renewable energy

price elasticities policy measures and actual developments in household energy consumption a bottom up analysis for the netherlands in the netherlands it seems likely that the large number of new policy measures in the past decade has influenced the response of households to changing prices to investigate this issue the energy trends in the period 1990 2000 have been simulated with a bottom up model applied earlier for scenario studies and extensive data from surveys for a number of alternative price cases the elasticity values found are explained using the bottom up changes in energy trends one finding is that the specific set of saving options defines for a great part the price response the price effect has been analysed too in combination with the policy measures standards subsidies and energy taxes the simulation results indicate that the elasticity value could be 30 40 higher without these measures

self selection and the earnings of immigrants this paper analyzes the way in which the earnings of the immigrant population may be expected to differ from the earnings of the native population because of the endogeneity of the decision to migrate the empirical study shows that differences in the u s earnings of immigrants with the same measured skills but from different home countries are attributable to variations in political and economic conditions in the countries of origin at the time of migration excerpt

the long reach of cotton in the us south tenant farming mechanization and low skill manufacturing abstract this paper examines the long run impact of cotton agriculture on local development in the us south focusing on a novel aspect of structural change exploiting climate based variation in cotton production i show that cotton specialization in the late 19th century had a negative impact on local development that lasts through 2010 this negative relationship however only became evident in the second half of the 20th century i argue that the change was caused by the mechanization of cotton production which began in the 1950s after the mechanization local manufacturing absorbed displaced cotton tenants with low human capital in response to the inflow of cotton tenants labor productivity in manufacturing began to decline and the effects persisted in the long run the persistent decline in manufacturing productivity is explained by directed technical change that reduced demand for skills in manufacturing these results indicate that depending on the agricultural background structural change can negatively affect the evolution of technology and productivity in the industrial sector

governance of co2 markets lessons from the eu ets the european emissions trading scheme eu ets is the centerpiece of europe s climate policy the system has been undermined variously by the weakness of its regulation an undesirable overlap with other public policies and the far reaching economic and financial crisis that caused the market price of allowances to plunge this article attempts to identify the conditions for making the coming years of the eu ets a success it draws historical lessons from the eight years the scheme has been in operation and then presents the various interventions by the public authorities currently under discussion in order to revive the market finally the article proposes to draw lessons from monetary policy by outlining what might be the mandate of an independent carbon market authority with responsibility for the dynamic management of the supply of allowances and whose main mission would be to ensure the optimal linkage between the different temporal horizons of the climate strategy this article could provide important lessons for schemes developing in the rest of the world especially in south korea or in china

do support systems for res e reduce eu ets driven electricity prices abstract support systems for electricity from renewable energy sources res e can reduce electricity prices which have also been influenced by a co2 emission trading scheme ets additional res e substitutes electricity from fossil fuels and thus co2 emissions are reduced the demand for emission reductions is lowered as a result the co2 price is also reduced consequently the wholesale price for electricity decreases however most res e support systems are financed via the electricity market which increases the retail electricity price an assessment for germany shows that retail electricity prices in the first trading period of the eu ets 2005 2007 are lowered by 2 6 euro mwh due to additional res e considering the complete eu the effect is substantially higher this paper describes the effect and the influence of different policy designs it develops an approach for assessing the effect and applies it for the case of germany and roughly estimates the effect for the eu

scaling the commanding heights of public enterprise economics there is a new orthodoxy in the economics of the public sector that has been promoted by privatization and for which ownership as such is essentially seen as irrelevant as compared to conditions of competition and regulation this is shown to depend upon an illegitimate and static view of the beneficial effects of competition a questionable distinction between natural and artificial monopoly a false history of the motives for and the performance of the nationalized industries a reduction of industrial to competition policy and a failure to examine intersectoral linkages rectifying these deficiencies suggests an alternative analytical and more favorable stance on public ownership copyright 1990 by oxford university press

regional differences in electricity distribution costs and their consequences for yardstick regulation of access prices abstract in this paper we estimate an average cost function for a panel of 59 swiss local and regional electricity distribution utilities as a basis for yardstick regulation of the distribution network access prices shleifer 1985 proposed yardstick competition in terms of price to regulate local monopolies producing a homogeneous good the regulated price for the individual firms depends on the average costs of identical firms the yardstick competition concept can also be applied to firms that produce heterogeneous goods if these goods differ only in observable characteristics to correct the yardstick for heterogeneity the regulator can use a multivariate estimation of an average cost function in the case of electricity distribution the heterogeneity of output consists mainly of different characteristics of the distribution service areas in this paper we follow shleifer s suggestion to estimate a multivariate average cost function that can be employed by the regulatory commission to benchmark network access prices at the distribution level several exogenous variables measuring the heterogeneity of the service areas were included in the cost model specification we find that the regional differences of the service areas e g area shares of forests agricultural areas or unproductive land and population density significantly influence electricity distribution costs

school quality and black white relative earnings a direct assessment the wage differential between black and white men fell from 40 percent in 1960 to 25 percent in 1980 it has been argued that this convergence reflects improvements in the relative quality of black schools to test this hypothesis we assembled data on pupil teacher ratios annual teacher pay and term length for black and white schools in the eighteen segregated states from 1915 to 1966 these data are linked to estimated returns to education for southern born men from different cohorts and states in 1960 1970 and 1980 improvements in the relative quality of black schools explain 20 percent of the narrowing of the black white earnings gap between 1960 and 1980

self selection and internal migration in the united states abstract within the conceptual framework of the roy model this paper provides an empirical analysis of internal migration flows using data from the national longitudinal survey of youth the theoretical approach highlights regional differences in the returns to skills regions that pay higher returns to skills attract more skilled workers than regions that pay lower returns our empirical results suggest that interstate differences in the returns to skills are a major determinant of both the size and skill composition of internal migration flows persons whose skills are most mismatched with the reward structure offered by their current state of residence are the persons most likely to leave that state and these persons tend to relocate in states which offer higher rewards for their particular skills
