the merit order effect of wind and river type hydroelectricity generation on turkish electricity prices abstract the environmental concerns and dependency on gas imports push turkish policy makers to find ways of increasing the share of renewable sources in electricity generation providing incentives for renewable energy in the form of feed in tariffs is one of the measures to achieve this goal basing on the data of turkish electricity market operator we quantified the magnitude of the price effects of wind and river type hydro generations on hourly average of day ahead prices we find that wind and river type hydro plants reduced the spot electricity prices during the period of 2012 2017 and despite these resources get the same incentives their impacts on the spot prices and price volatility are different this can be useful for a more comprehensive cost benefit analysis aimed at differentiating incentive schemes the paper also discusses possible underlying reasons of these different impacts such as high seasonality of hydro generation and volatility of wind generation finally we show that assuming more than 75 of the price reductions were reflected into the consumer prices in turkey the net impact of wind and river type hydro generation on final consumer prices would be negative this finding contributes to the discussions on renewable energy incentive mechanisms

learning by doing the technology gap and growth in contrast with other trade and growth theories in previous literature the author resents a growth theory of trade induced learning other things being equal two conditions are essential for trade induced learning first both exports and imports are equally important sources and are mutually reinforced in intensifying the learning process moreover the nature or characteristics of these traded goods also influence the effect of learning second trade openness is a prerequisite but not a sufficient condition for rapid growth with whom one trades one s trading partner is a key factor in determining trade induced technology spillover and hence in affecting enduring growth therefore this trade induced learning theory provides abundant and testable implications for the empirical study of trade and growth copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the impact of wind power generation on the electricity price in germany abstract this paper investigates the relationship between intermittent wind power generation and electricity price behaviour in germany using a garch model i evaluate the effect of wind electricity generation on the level and the volatility of the electricity price in an integrated approach the results show that variable wind power reduces the price level but increases its volatility this paper s results also indicate that regulatory change has stabilised the wholesale price the electricity price volatility has decreased in germany after a modification of the marketing mechanism of renewable electricity this gives confidence that further adjustments to regulation and policy may foster a better integration of renewables into the power system

empirical evidence on the relation between stock option compensation and risk taking abstract we examine whether executive stock options esos provide managers with incentives to invest in risky projects for a sample of oil and gas producers we examine whether the coefficient of variation of future cash flows from exploration activity our proxy for exploration risk increases with the sensitivity of the value of the ceo s options to stock return volatility eso risk incentives both eso risk incentives and exploration risk are treated as endogenous variables by adopting a simultaneous equations approach we find evidence that eso risk incentives has a positive relation with future exploration risk taking additional tests indicate that eso risk incentives exhibits a negative relation with oil price hedging in a system of equations where eso risk incentives and hedging are allowed to be endogenously determined overall our results are consistent with esos providing managers with incentives to mitigate risk related incentive problems

what does export diversification do for growth an econometric analysis it is frequently suggested that export diversification contributes to an acceleration of growth in developing countries horizontal export diversification into completely new export sectors may generate positive externalities on the rest of the economy as export oriented sectors gain from dynamic learning activities due to contacts with foreign purchasers and exposure to international competition vertical diversification out of primary into manufactured exports is also associated with growth since primary export sectors generally do not exhibit strong spillovers yet there have been remarkably few empirical investigations into the link between export diversification and growth this paper attempts to examine the hypothesis that export diversification is linked to economic growth via externalities of learning by doing and learning by exporting fostered by competition in world markets the diversification led growth hypothesis is tested by estimating an augmented cobb douglas production function on the bas

an evaluation of the transitional turkish electricity balancing and settlement market lessons for the future balancing and settlement market is a crucial part of restructured turkish electricity market in this framework the main purpose of this study is to examine whether the prices constituted in the transitional balancing and settlement market reflect the real cost of imbalances although it is observed that the prices are not powerful in indicating the real cost of imbalances turkey has the opportunity to form a well functioning market within the context of planned new market structure turkey needs to define a proper roadmap reckoning the points mentioned in this paper to be able to achieve her objectives

does eu enlargement increase agro food export duration this paper examines the impact of eu enlargement on agro food export performance across 12 new eu member states and five newly independent states in the eu markets covering the period 1999 to 2007 the performance is examined by duration of export and hazard model we find larger duration for the agro food exports from the new eu member states the results confirm gains from the eastward eu enlargement and governance on export increases and longer duration for exporting higher value added specialized consumer ready food and more competitive niche agro food products

human capital bankruptcy and capital structure we derive a firm s optimal capital structure and managerial compensation contract when employees are averse to bearing their own human capital risk while equity holders can diversify this risk away in the presence of corporate taxes our model delivers optimal debt levels consistent with those observed in practice it also makes a number of predictions for the cross sectional distribution of firm leverage consistent with existing empirical evidence it implies persistent idiosyncratic dierences in leverage across firms an important new empirical prediction of the model is that ceteris paribus firms with more leverage should pay higher wages

how product innovation in the north may immiserize the south a new look at the ricardian model with a continuum of goods abstract the paper proposes a theoretical model investigating the welfare consequences of technological shocks in a ricardian framework a la dornbush fisher and samuelson 1977 contrary to the existing literature the model incorporates a nonhomothetic demand function whose price and income elasticities are endogenously determined by technology nonhomothetic preferences are modeled as the result of the hierarchical consumption of luxury and necessity goods the nature of technical progress determines the consumption pattern and notably the magnitude of the substitution effect between necessities and luxuries the model is applied to the case of trade between two economies with different development levels it is shown in particular that the developing country can suffer a fall in utility as a result of technical progress in the developed country biased towards luxury goods this configuration depends on the size of the development gap and reflects the fact that southern goods are less attractive the higher the range of goods consumed this result suggests that there is an optimal level of development gap to avoid ldcs being harmed by technical progress in the north

managerial incentives risk aversion and debt we investigate the risk choices of risk averse ceos following recent theoretical work we expect ceo risk aversion to be more pronounced in firms with high leverage or high default probability we find that the ceos of these firms reduce firm risk even in the presence of strong risk taking incentives our results are robust to controls for the sensitivity of ceo wealth to stock price changes firm risk determinants the endogenous feedback effects of firm risk on ceo incentives unobserved firm and market effects and debt governance the impact of ceo risk aversion is economically significant

leverage decision and manager compensation with choice of effort and volatility abstract we study the incentive effects of granting levered or unlevered stock to a risk averse manager the stock is granted by risk neutral shareholders who choose leverage and compensation level the manager applies costly effort and selects the level of volatility both of which affect expected return the results are driven by the attempt of the risk neutral shareholders to maximize the value of their claims net of the compensation package we consider a dynamic setting and find that levered stock is optimal for high type managers firms with high momentum large firms and firms for which additional volatility only implies a modest increase in expected return

the volatility and price sensitivities of managerial stock option portfolios and corporate hedging we use estimates of the black scholes sensitivity of managers stock option portfolios to stock return volatility and the sensitivity of managers stock and stock option portfolios to stock price to test the relationship between managers risk preferences and hedging activities we find that as the sensitivity of managers stock and stock option portfolios to stock price increases firms tend to hedge more however as the sensitivity of managers stock option portfolios to stock return volatility increases firms tend to hedge less one of the agency costs associated with the corporate form of ownership comes from the risk aversion of the firm s managers the typical corporate manager has a significant portion of his or her wealth invested in the corporation both through portfolio holdings and the value of firm specific human capital as a result managers have an incentive to reduce firm risk more than may be desirable from the perspective of an unaffiliated diversified shareholder one way to mitigate managerial risk aversion is to provide the manager with contracts that have a payoff structure that is a convex function of the firm s stock price smith and stulz 1985 guay 1999 finds that stock options are an important way in which convexity is added to managers portfolios however as recognized by carpenter 2000 and lambert larcker and verrecchia 1991 stock options create two opposing effects on managerial incentives the first effect is sensitivity to stock return volatility due to the convex payoff structure of options the value of a manager s stock option portfolio increases with the volatility of the firm s stock returns this sensitivity to stock return volatility should ceteris paribus give the manager an incentive to take more risk the second effect is sensitivity to stock price this effect comes from the direct link between the payoff of an option and

design of an economically efficient feed in tariff structure for renewable energy development abstract evidence suggests albeit tentatively that feed in tariffs fits are more effective than alternative support schemes in promoting renewable energy technologies rets fits provide long term financial stability for investors in rets which at the prevailing market price of electricity are not currently cost efficient enough to compete with traditional fossil fuel technologies on the other hand if not properly designed fits can be economically inefficient as is widely regarded to have been the case under the public utility regulatory policies act of 1978 purpa under purpa too high a guaranteed price led to the creation of so called purpa machines poorly performing generating units that could survive financially only because of heavy subsidies that came at the expense of retail customers similarly because of their adverse impacts on retail electricity rates german fits have been subject to increasing political pressure from utilities and customers in this paper we propose an innovative two part fit consisting of both a capacity payment and a market based energy payment which can be used to meet the renewables policy goals of regulators our two part tariff design draws on the strengths of traditional fits relies on market mechanisms is easy to implement and avoids the problems caused by distorting wholesale energy markets through above market energy payments the approach is modeled on forward capacity market designs that have been recently implemented by several regional transmission organizations in the usa to address needs for new generating capacity to ensure system reliability

economic guideline about financial utilization of flat plate solar collectors fpscs for the consumer segment in the city of eskisehir abstract solar energy systems yield energy savings relative to conventional systems by considering the ecological balance although it still has barriers the most commonly used system of this type is fpsc in turkey which produces hot water by absorbing solar energy through fpscs this study is a kind of guidance about utilization of fpscs in eskisehir that concentrates on a consumer segment the aim of the study is displaying the necessity of transition to renewable energy systems in the local free markets where the place of domestic resources the data is supplied from an original hand collected survey and turkish governmental institutions such as the central bank of the republic of turkey cbrt and the turkish statistical institute turkstat that is used for a possible scenario to show how these systems can become an extensive investment and financed in the city the most significant finding is purchasing a fpsc device which is a rational and profitable investment decision for households in the economic conditions of eskisehir this type of energy system has certain costs including installation credit and annual maintenance costs however after they have been set up fpsc systems yield many ecological advantages that more than offset the associated costs such as fuel savings over the long term and exemptions from tax payments that apply to other types of fuels these advantages benefit both the environment on a global scale and the region in which the system is constructed therefore the global and local economy can improve its structure by utilizing fpscs

recent incentives for renewable energy in turkey abstract recently the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy in the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil natural gas and coal alternative energy sources renewables are increasingly needed to respond to the threat of climate change and growing energy demand in the world recent developments in turkey such as the liberalization of the electricity market and improvements in the renewable legislations have accelerated the growth process and investment opportunities in the field of renewable energy turkey s naturally endowed potential for renewables such as solar geothermal and wind also accompanied these developments and attracted world attention to this market in turkey renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources this study aims to explore the availability and potential of renewable energy sources in turkey and discuss the government policies and economic aspects

renewable energy in turkey great potential low but increasing utilization and an empirical analysis on renewable energy growth nexus abstract concerns about the exhaustion of fossil energy sources energy security problems and increasing environmental problems have led policy makers to pay greater attention to renewable energy sources all over the world additionally high current account deficits stemming from energy import dependency make substitution of fossil energy with renewable energy a necessity for turkey although turkey has a great potential in terms of renewable energy it has not begun to utilize this great potential until recent years however turkey has many motives to utilize renewable energy further this paper aims to investigate whether renewable energy consumption raises gdp in turkey for this purpose the paper uses data spanning the period 1990 2015 and employs cointegration and causality tests which can present efficient output in small samples the findings indicate that gdp is not related to renewable energy consumption and there is no causality between gdp and renewable energy consumption in turkey in conclusion the paper argues that these findings may stem from the low share of renewable energy in total energy and turkey needs to utilize renewable energy sources further to i meet energy needs for economic activities ii mitigate environmental problems and iii reduce energy import dependency and current account imbalances

the match between ceo and firm we investigate the role of job match heterogeneity in the ceo labor market we document a high percentage of ceo turnovers in the early years of tenure as illustrated by the hazard that increases until the fifth year of ceo tenure and then decreases evidence suggests that a good match is more likely if the new ceo performs better than the previous ceo the best matches tend to occur when inside outside ceos follow previous ceos who quit are dismissed evidence consistent with match theory in the ceo labor market suggests factors that influence the likelihood of observing a good match

the impact of performance based compensation on misreporting abstract this paper examines the effect of ceo compensation contracts on misreporting we find that the sensitivity of the ceo s option portfolio to stock price is significantly positively related to the propensity to misreport we do not find that the sensitivity of other components of ceo compensation i e equity restricted stock long term incentive payouts and salary plus bonus have any significant impact on the propensity to misreport relative to other components of compensation stock options are associated with stronger incentives to misreport because convexity in ceo wealth introduced by stock options limits the downside risk on detection of the misreporting

solar feed in tariffs and the merit order effect a study of the german electricity market abstract this study investigates the merit order effect moe of the recent years implementation of solar power in germany market clearing electricity prices and production levels are compared for the years 2009 2011 and a model for the relationship between the electricity price and price sensitive electricity production is developed and applied to predict electricity prices in germany from july 2010 to july 2011 with and without solar electricity generation seg the results show that the seg has caused a 7 reduction in average electricity prices for this period the average daily maximum price and daily price variation are also found to decrease by 13 and 23 respectively when taking the moe into account the net consumer s cost of the solar feed in tariff fit system is found to be 23 less than the charge listed in the electricity bill the german fit policy for solar power has been subject to considerable public debate and a common argument brought up in disfavor of the system is the high cost for the consumers in this study we demonstrate the importance of including the moe when evaluating the total costs and benefits of the fit policy mechanism

executive compensation and the maturity structure of corporate debt executive compensation influences managerial risk preferences through executives portfolio sensitivities to changes in stock prices delta and stock return volatility vega large deltas discourage managerial risk taking while large vegas encourage risk taking theory suggests that short maturity debt mitigates agency costs of debt by constraining managerial risk preferences we posit and find evidence of a negative positive relation between ceo portfolio deltas vegas and short maturity debt we also find that short maturity debt mitigates the influence of vega and delta related incentives on bond yields overall our empirical evidence shows that short term debt mitigates agency costs of debt arising from compensation risk

fdi trade and spillover efficiency evidence from china s manufacturing sector using firm data from the 1995 third industrial census of china this paper finds that the presence of foreign ownership has a positive and significant effect on domestic firms productivity moreover trading with more advanced countries helps china gain access to new technology and information which improves its productivity and enables it to compete in international markets it is found that china s imports from oecd and the four asian tigers and exports to oecd have positive effects on domestic firms productivity by dividing industries into high technology gap and low technology gap groups it is found that the spillover effects of fdi are larger for the low technology gap group than for the high technology gap group however the estimation results of the trade induced technology spillover effect support the technology gap learning theory and the significance of importing appropriate technology

the impact of renewable energies on eex day ahead electricity prices in this paper we analyze the impact of renewable energies wind and photovoltaic on the formation of day ahead electricity prices at eex we give an overview of the policy decisions concerning the promotion of renewable energy sources in germany and discuss their consequences on day ahead prices an analysis of electricity spot prices reveals that the introduction of renewable energies enhances extreme price changes in the frame of a dynamic fundamental model we show that there has been a continuous electricity price adaption process to market fundamentals furthermore the fundamental drivers of prices differ among hours with different load profiles our results imply that renewable energies decrease market spot prices and have implications on the traditional fuel mix for electricity production however the prices for the final consumers increased overall because they must pay in addition the feed in tariffs for the promotion of renewable energy

an ex post analysis of the effect of renewables and cogeneration on spanish electricity prices abstract growing concerns about climate change and energy dependence are driving specific policies to support renewable or more efficient energy sources such as cogeneration in many regions particularly in the production of electricity these policies have a non negligible cost and therefore a careful assessment of their impacts seems necessary in particular one of the most debated impacts is their effect on electricity prices for which there have been some ex ante studies but few ex post studies this article presents a full ex post empirical analysis by looking at use of technologies and hourly electricity prices for 2005 2009 in spain to study the effects that the introduction of renewable electricity and cogeneration has had on wholesale electricity prices it is particularly interesting to perform this study in spain where an active system of public support to renewables and cogeneration has led to a considerable expansion of these energy sources and electricity pricing is at the center of intense debate the paper reports that a marginal increase of 1 gwh of electricity production using renewables and cogeneration is associated with a reduction of almost 2 per mwh in electricity prices around 4 of the average price for the analyzed period

ceo compensation in financially distressed firms an empirical analysis this paper studies senior management compensation policy in 77 publicly traded firms that filed for bankruptcy or privately restructured their debt during 1981 to 1987 almost one third of all ceos are replaced and those who keep their jobs often experience large salary and bonus reductions newly appointed ceos with ties to previous management are typically paid 35 less than the ceos they replace in contrast outside replacement ceos are typically paid 36 more than their predecessors and are often compensated with stock options on average ceo wealth is significantly related to shareholder wealth after firms renegotiate their debt contracts however managers compensation is sometimes explicitly tied to the value of creditors claims

estimating the value of employee stock option portfolios and their sensitivities to price and volatility the costs associated with compiling data on employee stock option portfolios is a substantial obstacle in investigating the impact of stock options on managerial incentives accounting choice financing decisions and the valuation of equity we present an accurate method of estimating option portfolio value and the sensitivities of option portfolio value to stock price and stock return volatility that is easily implemented using data from only the current year s proxy statement or annual report this method can be applied to either executive stock option portfolios or to firm wide option plans in broad samples of actual and simulated ceo option portfolios we show that these proxies capture more than 99 of the variation in option portfolio value and sensitivities sensitivity analysis indicates that the degree of bias in these proxies varies with option portfolio characteristics and is most severe in samples of ceos with a large proportion of out of the money options however the proxies explanatory power remains above 95 in all subsamples

top management compensation and capital structure the interrelationship between top management compensation and the design and mix of external claims issued by a firm is studied the optimal managerial compensation structures depend on not only the agency relationship between shareholders and management but also the conflicts of interests which arise in the other contracting relationships for which the firm serves as a nexus we analyze in detail the optimal management compensation for the cases when the external claims are 1 equity and risky debt and 2 equity and convertible debt in addition to the role of aligning managerial incentives with shareholder interests managerial compensation in a levered firm also serves as a precommitment device to minimize the agency costs of debt the optimal management compensation derived has low pay performance sensitivity with convertible debt instead of straight debt the corresponding optimal managerial compensation has high pay to performance sensitivity a negative relationship between pay performance sensitivity and leverage is derived our results provide a reconciliation of the puzzling evidence of jensen and murphy 1990 with agency theory other testable implications include 1 a relationship between the risk premium in corporate bond yields and top management compensation structures and 2 the announcement effect of adoption of executive stock option plans on bond prices the model yields implications for management compensation in banks and federal deposit insurance reform our results explain the dynamics of top management compensation in firms going through financial distress and reorganization

lower salaries and no options on the optimal structure of executive pay we estimate a standard principal agent model with constant relative risk aversion and lognormal stock prices for a sample of 598 us ceos the model is widely used in the compensation literature but it predicts that almost all of the ceos in our sample should hold no stock options instead ceos should have lower base salaries and receive additional shares in their companies for a typical value of relative risk aversion almost half of the ceos in our sample would be required to purchase additional stock in their companies from their private savings the model predicts contracts that would reduce average compensation costs by 20 while providing the same incentives and the same utility to ceos we investigate a number of extensions and modi cations of the standard model but nd none of them to be satisfactory we conclude that the standard principal agent model typically used in the literature cannot rationalize observed contracts one reason may be that executive pay contracts are suboptimal

putting things in order trade dynamics and product cycles we develop a procedure to rank order objects using censored panel data sets we illustrate this by ranking countries and commodities using disaggregated american import data and find evidence that

compensation incentives and the duality of risk aversion and riskiness the common folklore that giving options to agents will make them more willing to take risks is false in fact no incentive schedule will make all expected utility maximizers more or less risk averse this paper finds simple intuitive necessary and sufficient conditions under which incentive schedules make agents more or less risk averse the paper uses these to examine the incentive effects of some common structures such as puts and calls and it briefly explores the duality between a fee schedule that makes an agent more or less risk averse and gambles that increase or decrease risk with the growing interest in executive compensation and agency problems

manufacturing exports mining exports and growth cointegration and causality analysis for chile 1960 2001 this study examines the export led growth hypothesis using annual time series data from chile in a production function framework it addresses the problem of specification bias under which previous studies have suffered and focuses on the impact of manufactured and mining exports on productivity growth in order to investigate if and how manufactured and mining exports affect economic growth via increases in productivity the study uses johansen cointegration technique the estimation results can be interpreted as evidence of productivity enhancing effects of manufactured exports and of productivity limiting effects of mining exports

does option compensation increase managerial risk appetite this paper solves the dynamic investment problem of a risk averse manager compensated with a call option on the assets he controls under the manager s optimal policy the option ends up either deep in or deep out of the money as the asset value goes to zero volatility goes to infinity however the option compensation does not strictly lead to greater risk seeking sometimes the manager s optimal volatility is less with the option than it would be if he were trading his own account furthermore giving the manager more options causes him to reduce volatility managers with convex compensation schemes play an important role in financial markets this paper solves for the optimal dynamic investment policy for a risk averse manager paid with a call option on the assets he controls the paper focuses on how the option compensation impacts the manager s appetite for risk when he cannot hedge the option position on one hand the convexity of the option makes the manager shun payoffs that are likely to be near the money under the optimal policy the manager either significantly outperforms his benchmark or else incurs severe losses furthermore in examples of optimal trading strategies asset volatility goes to infinity as asset value goes to zero yet option compensation does not strictly lead to greater risk seeking as asset value grows large or if the evaluation date is far away the manager moderates asset risk for example if the manager has constant relative risk aversion crra asset volatility converges to the merton constant as asset value goes to infinity in some situations the manager actually chooses a lower asset volatility than he would if he were investing on his own because the leverage inherent in his option magnifies his exposure to the asset volatility in addition with all constant or decreasing absolute risk averse utility functions from the hyperbolic absolute risk averse hara class giving the manager more options causes him to reduce asset volatility in the crra case for example the manager targets a fixed volatility for his personal

is green energy expensive empirical evidence from the spanish electricity market abstract renewable energy promotion and its cost are at the heart of the energy policy debate in many countries the question from an economic perspective is how expensive the promotion of renewable sources through price based incentive schemes is this paper addresses this issue empirically we analyze the spanish electricity market during the period 2008 2012 where renewable energy production rose by 57 to determine how expensive it was we first measure the savings due to the spot price reduction driven by the merit order effect and second we compute the amount paid as incentives to green energy by the electricity system the difference between the two is the net cost of green energy to the electricity markets we present aggregate results for renewable sources as a whole as well as individual results for each technology we show that at the initial stages when renewable capacity was low green energy promotion paid for itself 2008 2009 however from 2010 on when renewable production reached a relatively high level it started to impose a positive net cost on the system finally we found substantial differences among technologies wind energy implied the lowest net cost while solar photovoltaic was the most expensive

the export skill content learning by exporting and economic growth abstract we empirically investigate whether countries export mix influences their economic growth using panel data from 86 countries covering the period between 1970 and 1990 we identify a statistically significant positive relationship between export skill content and economic growth the evidence supports the idea that after controlling for the levels of gdp per capita education openness to foreign trade and political and macroeconomic stability a higher export content of skill intensive goods generates higher per capita gdp growth rates

too much of a good incentive the case of executive stock options abstract using a utility maximization framework i show that the incentive to increase stock price does not always increase as more options are granted keeping the total cost of his compensation fixed granting more options creates greater incentives to increase stock price only if option wealth does not exceed a certain fraction of total wealth beyond this critical level granting more options actually reduces incentive effects and becomes counterproductive in addition stock options also create incentive to reduce increase idiosyncratic systematic risk these incentive effects are sensitive to the choice of exercise price

moving up or moving out a unified theory of r d fdi and trade abstract this paper introduces industrial heterogeneity in r d productivity into the quality ladder model of the north south trade to study how firms choices made between r d and foreign direct investment fdi vary across industries and how such choices consequently determine the evolution of comparative advantage and trade it shows that trade reveals product cycle dynamics in medium tech industries but remains static in others high tech industries experience continued innovation in the north with no migration of product lines medium and low tech industries migrate south via fdi to exploit low production costs with the south then replacing the north as the dominant exporter however medium tech industry production eventually shifts back to the north when superior products are marketed by northern innovators making the end of one complete product cycle and the start of the next because of marginal r d productivity the relocated low tech industries are not presented with the option of moving up and thus stagnate

managerial incentives and capital management the paper shows how career concerns rather than effort aversion can induce a natural incongruity in risk preferences between managers and superiors a model based on learning about managerial talent is developed to study second best contractual remedies we show that the optimal wage contract is an option of the value of the manager s human capital for insurance reasons and that consequently rationing of capital is often required to counterbalance the manager s resulting incentive to overinvest rationing is strictly superior to price decentralization offering one reason for the prevalence of centralized capital budgeting procedures

the merit order effect of wind and photovoltaic electricity generation in germany 2008 2016 estimation and distributional implications abstract generation from renewable energy sources in germany has experienced a considerable uptake in recent years mainly responsible for this development is the german renewable energy sources act erneuerbare energien gesetz eeg this paper considers redistributive implications of the eeg for different electricity consumers using time series regression analysis we show that electricity generation by wind and pv has reduced spot market prices considerably by 6 mwh in 2010 rising to 10 mwh in 2012 we use these results to build a near term forecasting tool for merit order effects projected to reach 14 16 mwh in 2016 on the other hand the costs of the eeg are passed forward to consumers in the form of a surcharge our findings highlight significant redistributive transfers under the current design of the eeg in particular some energy intensive industries are benefiting from lower wholesale electricity prices whilst being largely exempted from contributing to the costs of the scheme we also highlight implications of our results for other areas for reform of the eeg such as adequate remuneration mechanisms that ensure efficient operation and investment decisions are made under the scheme more generally these findings suggest that policy makers need to integrate distributional assessments into policy design and implementation
