feed in tariffs for promotion of energy storage technologies faster market integration of new energy technologies can be achieved by use of proper support mechanisms that will create favourable market conditions for such technologies the best examples of support mechanisms presented in the last two decades have been the various schemes for the promotion of renewable energy sources res in the eu the most successful supporting schemes are feed in tariffs which have significantly increased utilisation of renewable energy sources in germany spain portugal denmark and many other eu countries despite the successful feed in tariffs for res promotion in many cases res penetration is limited by power system requirements linked to the intermittency of res sources and technical capabilities of grids these problems can be solved by implementation of energy storage technologies like reversible or pumped hydro hydrogen batteries or any other technology that can be used for balancing or dump load in this paper feed in tariffs for various energy storage technologies are discussed along with a proposal for their application in more appropriate regions after successful application on islands and outermost regions energy storage tariffs should be also applied in mainland power systems increased use of energy storage could optimise existing assets on the market

drawn into violence evidence on what makes a criminal from the vietnam draft lotteries draft lottery number assignment during the vietnam era provides a natural experiment to examine the effects of military service on crime using exact dates of birth for inmates in state and federal prisons in 1979 1986 and 1991 we find that draft eligibility increases incarceration for violent crimes but decreases incarceration for nonviolent crimes among whites this is particularly evident in 1979 where two sample instrumental variable estimates indicate that military service increases the probability of incarceration for a violent crime by 0 34 percentage points and decreases the probability of incarceration for a nonviolent crime by 0 30 percentage points we conduct two falsification tests one that applies each of the three binding lotteries to unaffected cohorts and another that considers the effects of lotteries that were not used to draft servicemen jel k42 h56

on strategic community development this paper examines strategic behavior of developers who through offering different congested public good packages and revenue fiscal schemes compete for residents who are differentiated by income there is an endogenous determination of numbers and sizes of communities developers have an incentive to strongly differentiate their public good offerings in terms of pricing strategies developers exhibit sharply contrasting behaviors in low income communities housing consumption is subsidized once lots are priced in high income communities housing consumption is generally taxed

on the pricing strategy of a land developer this paper examines the pricing strategy of a developer facing potential clients heterogeneous in income two part pricing and second degree discriminatory pricing strategies are characterized our results include the fact that the developer chooses either to charge a positive entry fee and a unit housing price above cost or to charge linear pricing of housing depending on the share of housing in individual consumption as well as on the quality level of public services second degree discriminatory pricing improves upon the ability of the developer to exploit high income consumers c 1999 academic press

the long term impact of military service on health evidence from world war ii and korean war veterans during the world war ii and korean war era the u s military freely distributed cigarettes to overseas personnel and provided low cost tobacco products on domestic military bases in fact even today the military continues to sell subsidized tobacco products on its bases using a variety of instrumental variables approaches to deal with nonrandom selection into the military and into smoking we provide substantial evidence that cohorts with higher military participation rates subsequently suffered more premature mortality more importantly we show that a large fraction 35 to 79 percent of the excess veteran deaths due to heart disease and lung cancer are attributable to military induced smoking

going to college to avoid the draft the unintended legacy of the vietnam war between 1965 and 1975 the enrollment rate of college age men in the united states rose and then fell abruptly many contemporary observers e g james davis and kenneth dolbeare 1968 attributed the surge in college attendance to draft avoidance behavior under a policy first introduced in the korean war the selective service issued college deferments to enrolled men that delayed their eligibility for conscription these deferments provided a strong incentive to remain in school for men who wanted to avoid the draft for example the college entry rate of young men rose from 54 percent in 1963 to 62 percent in 1968 the peak year of the draft moreover both the college entry rate and the number of inductions dropped sharply between 1968 and 1973 as the draft was being phased out although these parallel trends are suggestive they do not necessarily prove that draft avoidance raised the education of men who were at risk of service during the vietnam war such an inference requires an explicit specification of the counterfactual what would have happened to schooling outcomes in the absence of the draft in this paper we use trends in enrollment and completed schooling of men relative to those of women to measure the effects of draftavoidance behavior during the vietnam war our maintained hypothesis is that in the absence of gender specific factors such as the draft the relative schooling outcomes of men and women from the same cohort would follow a smooth trend in light of the sharp discontinuity in military induction rates between 1965 and 1970 we look for similar patterns in the relative enrollment rate of men and in the relative college graduation rate of men from cohorts that were at risk of induction during this period

demand for education and labor market outcomes lessons from the abolition of compulsory conscription in france before 1997 education was a way for young french men to avoid military service in the army after the abolition of compulsory conscription in 1997 this incentive to stay on in education disappeared we show that the decrease in the benefit of pursuing education for men was followed by a fall in their educational achievement relative to women and by a decrease in their relative entry wages these results suggest that high school dropout rates could be reduced by policies increasing the immediate benefits of pursuing education and that it would yield a substantial improvement in early labor market outcomes

lifetime earnings and the vietnam era draft lottery evidence from social security administrative records errata the randomly assigned risk of induction generated by the draft lottery is used to construct estimates of the effect of veteran status on civilian earnings these estimates are not biased by the fact that certain types of men are more likely than others to service in the military social security administrative records indicate that in the early 1980s long after their service in vietnam had ended the earnings of white veterans were approximately 15 percent less than the earnings of comparable nonveterans copyright 1990 by american economic association

revenue implications of money creation under leviathan most governments possess a monopoly franchise in the creation of money economists provide an analytical justification for this institutional arrangement either in terms of the use of monetary aggregates for macro economic stabilization or in terms of the alleged inability of competitive markets to generate tolerably efficient monetary results any complete case for the government s monetary monopoly must however depend on a comparison of market and political arrangements a comparison that requires predictions about how governments are likely to behave once a monopoly franchise is assigned similarly such predictions are crucial in evaluating restrictions that might be imposed on the government s exercise of its money creation power in designing a monetary constitution in the analysis of political arrangements the revenue implications of the money creation power are probably more significant than considerations of either macro economic stability or optimality in the money supply although those revenue implications are incidental to demonstrating the nature of market failure in monetary arrangements they are fundamental in understanding how the government might exploit a monopoly in money creation once granted our interest in the revenue effects of money creation stems from a broader study of constitutional restrictions on the revenueraising authority of government see our book the power to create money is naturally encompassed in this restrictions on the revenue raising power must embody restrictions on the power to create money consequently the fiscal constitution has important implications for the monetary constitution in this paper we examine both the revenue implications of money creation and desirable consitutional restrictions on the money creation power within the context of a specific model of political processes

monopoly with incomplete information recent theoretical research on principal agent relationships has emphasized incentive problems that arise when the parties involved are constrained by either asymmetric information or their inability to monitor each other s actions here we concentrate on the former constraint and consider the case of a single principal the monopolist the main contribution is to show that under a separability assumption strong conclusions can be drawn about the nature of optimal incentive schemes although the primary focus is on optimal quantity discounts in a monopolized market the results also shed light on related topics such as optimal income taxation and commodity bundling

assessing the advantages and drawbacks of government trading of guarantees of origin for renewable electricity in europe abstract the european commission has proposed a new renewable energy directive which includes flexibility provisions allowing the cost effective attainment of the ambitious target for renewable energy of 20 of energy consumption which has been set for the year 2020 one of the flexibility provisions currently being considered is to allow countries to reach their individual targets by buying their renewable electricity deployment deficit from other countries with a surplus i e with a renewable electricity deployment above their targets this trade is likely to take the form of an exchange in guarantees of origin gos gos are currently implemented in member states to fulfil the renewable electricity directive requirement that each country has a system that allows the tracing of the source of each kwh of renewable electricity and informs on this source although the recent and tiny literature on the analysis of go trading has focused on trade between firms the exchange of gos between governments has not received a comparable attention this paper analyses the advantages and drawbacks of a system of government trading of gos with respect to company trading

conscription and the returns to education evidence from a regression discontinuity in 1997 the french government put into effect a law that permanently exempted young french male citizens born after jan 1 1979 from mandatory military service while still requiring those born before that cutoff date to serve this paper uses a regression discontinuity design to identify the effect of peacetime conscription on education and labor market outcomes results indicate that conscription eligibility induces a significant increase in years of education which is consistent with conscription avoidance behavior however this increased education does not result in either an increase in graduation rates or in employment and wages additional evidence shows conscription has no direct effect on earnings suggesting that the returns to education induced by this policy was zero

on the political economy of zoning abstract households choose a community in a metropolitan area and collectively set a minimum housing quality and a property tax to finance a local public good the collective imposition of a lower bound on housing consumption induces an income stratified equilibrium in a specification where meaningful community differentiation would not arise without zoning we show computationally that zoning restrictions are likely to be stringent with a majority facing a binding constraint in communities that permit it by inducing a stratified equilibrium zoning causes tiebout welfare gains in aggregate but with large welfare transfers relative to stratified equilibrium without zoning the zoning equilibrium is significantly more efficient as it reduces housing market distortions

estimating marginal returns to education this paper estimates marginal returns to college for individuals induced to enroll in college by different marginal policy changes the recent instrumental variables literature seeks to estimate this parameter but in general it does so only under strong assumptions that are tested and found wanting we show how to utilize economic theory and local instrumental variables estimators to estimate the effect of marginal policy changes our empirical analysis shows that returns are higher for individuals with values of unobservables that make them more likely to attend college we contrast our estimates with iv estimates of the return to schooling

did vietnam veterans get sicker in the 1990s the complicated effects of military service on self reported health abstract the veterans disability compensation vdc program which provides a monthly stipend to disabled veterans is the third largest american disability insurance program since the late 1990s vdc growth has been driven primarily by an increase in claims from vietnam veterans raising concerns about costs as well as health we use the draft lottery to study the long term effects of vietnam era military service on health and work in the 2000 census we find no evidence that military service affected overall employment rates or overall work limiting disability rates that is health conditions that make work difficult at the same time military service sharply increased federal transfer income especially for lower skilled white men among whom there was also a large negative impact on employment and a marked increase in disability rates the differential impact of vietnam era service on low skilled men cannot be explained by more combat or war theatre exposure for the least educated because high school graduates were at least as likely to be exposed to combat or war theatre as the less educated this leaves the relative attractiveness of vdc for less skilled men and the work disincentives embedded in the vdc system as a likely explanation for our findings

a capacity investment model of wind power with uncertain supply price under high penetration rate abstract with the rapid development of renewable energy the proportion of wind power in power supply has grown significantly also it influences the power price fluctuation since the marginal cost of wind power is almost zero the growth of wind power s penetration rate has led to a crowding out effect and challenged traditional power generation technology substantially reducing the power price in the market in perfect competition market the real time balance between supply and demand of power is regulated by the real time power price fluctuation so this paper models the intermittence of wind power as uncertain supply and develops a capacity investment model under the uncertainties of both supply and demand we introduce priority dispatch elasticity to describe the crowding out effect and take the power price to be endogenous in order to model the situation of high penetration rate we compare the optimal wind power capacity decision under the strategy of priority grid connection and abandoned power management our results show that optimal capacity investment is inversely related to priority dispatch elasticity under both strategies however the profit from power generation is always higher when adopting the abandoned power management strategy

transparency and value chain sustainability the rise of transparency on the public and political agendas is not an accident or fad soon to be replaced by another timely topic in sustainability politics and governance transparency will remain a key topic in global value chains and will further develop as it piggy backs on wider social developments such as globalization the information age and the shifting role of states in environmental governance transparency in value chains is bound up with positive connotations the more transparency the better it is for the sustainability of chains and for the empowerment of consumers and civil society but an overall positive past assessment of value chain transparency does not automatically extend into the future as new challenges lie ahead this paper investigates the new challenges for value chain transparency and their consequences due to the growing importance attached to transparency in value chains it becomes a central object of power struggles with uncertain outcomes markets and states seek to capture transparency arrangements for their own goals which may not be in line with the assumed normative linkages between value chain transparency and increased power for consumers and civil society in that sense transparency is losing its innocence more transparency is no longer always the best for citizen consumer empowerment and for the sustainability of value chains but value chain secrecy is not an attractive alternative this opens a new research agenda on how transparency should be organized and arranged in value chains to live up to the promises of democracy and sustainability

design options for cooperation mechanisms under the new european renewable energy directive abstract in june 2009 a new eu directive on the promotion of renewable energy sources res entered into effect the directive 2009 28 ec provides for three cooperation mechanisms that will allow member states to achieve their national res target in cooperation with other member states statistical transfer joint projects and joint support schemes this article analyses the pros and cons of the three mechanisms and explores design options for their implementation through strategic and economic questions how to counterbalance the major drawbacks of each mechanism how to reflect a balance of costs and benefits between the involved member states the analysis identifies a number of design options that respond to these questions e g long term contracts to ensure sufficient flexibility for statistical transfers a coordinated standardised joint project approach to increase transparency in the european market and a stepwise harmonisation of joint support schemes that is based on a cost effective accounting approach one conclusion is that the three cooperation mechanisms are closely interlinked one can consider their relation to be a gradual transition from member state cooperation under fully closed national support systems in case of statistical transfers to cooperation under fully open national support systems in a joint support scheme

evaluating the labor market effects of compulsory military service we identify the causal effect of compulsory military service on conscripts subsequent labormarket outcomes by exploiting the regression discontinuity design of the military draft in germany during the 1950s unbiased estimates of the effect of military service on lifetime earnings wages and employment are obtained by comparing men born before july 1 1937 the white cohort who were exempted from compulsory military service to men who were born on or shortly after this threshold date and hence faced a positive probability of being drafted we find that the putative earnings advantage and wage premium of those who served in the armed forces vanish when selection effects are taken into account

sustainability guided promotion of renewable electricity generation in recent years the threat of global climate change high fuel import dependence and rapidly rising electricity demand levels have intensified the quest for more sustainable energy systems this in turn has increased the need for policy makers to promote electricity generation from renewable energy sources guaranteed prices coupled with a buy back obligation for electricity fed into the grid is a popular renewables promotion instrument especially in europe more recently driven mainly by electricity market liberalisation efforts quota targets for the share of renewables in combination with tradable green certificates tgc have received considerable attention tgc offer a greater theoretical potential for economic efficiency gains due to price competition and the greater flexibility assigned to the obliged parties while guaranteed prices and tgc schemes support the operation of renewable energy technology systems bidding schemes for renewable energy generation capacity are used to raise economic efficiency on the plant construction side all of these policy instruments suffer from the shortcoming that they do not explicitly account for the often widely varying environmental social and economic impacts of the technologies concerned in this paper we propose a methodology for the design of renewable energy policy instruments that is based on integrated assessment in particular we argue that using participatory multicriteria evaluation as part of the design of renewable energy promotion policies would make it possible 1 to differentiate the level of promotion in a systematic and transparent manner according to their socio ecological economic impact and 2 to explicitly account for the preferences of stakeholders a further problem of existing tgc and bidding schemes is that diversity of supply could be severely diminished if few low cost technologies were allowed to dominate the renewable energy market to ensure a certain diversity of technologies our scheme suggests the use of different technology bands for technologies that are relatively homogeneous with respect to their maturity

segmenting the market the monopolist s optimal product mix abstract in an industry producing products which differ in quality to consumers who vary in their willingness to pay it may happen that only a bounded number of producers can coexist at noncooperative price equilibrium in other words the industry is a natural oligopoly we are here concerned with a special example in which only one producer can survive our focus of interest in the present paper is to examine this monopolist s optimal product range depending on the dispersion of consumers willingness to pay income either i the monopolist will find it optimal to segment the market completely offering the maximum number of products permitted or ii the monopolist will offer only a single product the precise nature of this switch of policy which occurs at a certain critical distribution of consumer incomes willingness to pay is explored fully

is extending compulsory schooling alone enough to raise earnings evidence from french and british compulsory schooling laws in this paper i compare two reforms that raised the minimum school leaving age to 16 in france 1967 and in england and wales 1972 using a regression discontinuity design i find that while the reform in england and wales led to a 6 7 percent increase in hourly wages per additional year of compulsory schooling the impact of the change to french law was close to zero the results suggest that the major difference between the two reforms was that the fraction of individuals holding no qualifications dropped sharply after the introduction of the new minimum school leaving age in england and wales whereas it remained unchanged in france

zero returns to compulsory schooling in germany evidence and interpretation abstract we estimate the impact of compulsory schooling on earnings using changes in compulsory schooling laws in west germany after world war ii most estimates in the literature indicate returns in the range of 10 to 15 while our research design is very similar to studies for various other countries we find a zero return we find no evidence that this is due to labor market institutions or the apprenticeship training system in germany the result might be due to the fact that the basic skills most relevant for the labor market are learned earlier in germany than in other countries

military service and political behavior evidence from france abstract we investigate the impact of compulsory military service on turnout and political preferences exploiting the suspension of mandatory conscription for french men we observe a significant and positive impact of military service on turnout we estimate that the service increases turnout by approximately 7 percentage points we also investigate the impact of conscription on political preferences when we control for selection into the military service we observe no support for a change in preferences of former conscripts

social interactions in high school lessons from an earthquake after an earthquake hit southern italy in 1980 young men from certain towns were exempted from compulsory military service we show that the exemption raised high school graduation rates of boys by more than 2 percentage points we do this by comparing high school graduation rates of young exempt men and older nonexempt men from the least damaged areas and men of the same age groups from nearby towns that were not hit by the quake similar comparisons show that graduation rates of young women in the affected areas also increased since in italy women are not subject to the draft the findings suggest the presence of spillover effects jel i21 j13
