the impact of climate targets on future steel production an analysis based on a global energy system model this paper addresses how a global climate target may influence iron and steel production technology deployment and scrap use a global energy system model etsap tiam was used and a scrap availability assessment model saam was developed to analyse the relation between steel demand recycling and the availability of scrap and their implications for steel production technology choices steel production using recycled materials has a continuous growth and is likely to be a major route for steel production in the long run however as the global average of in use steel stock increases up to the current average stock of the industrialised economies global steel demand keeps growing and stagnates only after 2050 due to high steel demand levels and scarcity of scrap more than 50 of the steel production in 2050 will still have to come from virgin materials hydrogen based steel production could become a major technology option for production from virgin materials particularly in a scenario where carbon capture and storage ccs is not available imposing a binding climate target will shift the crude steel price to approximately 500 usd per tonne in the year 2050 provided that ccs is available however the increased prices are induced by co2 prices rather than inflated production costs it is concluded that a global climate target is not likely to influence the use of scrap whereas it shall have an impact on the price of scrap finally the results indicate that energy efficiency improvements of current processes will only be sufficient to meet the climate target in combination with ccs new innovative techniques with lower climate impact will be vital for mitigating climate change

stock option repricing and its alternatives an empirical examination in this paper i examine the likelihood of ceo stock option repricing and its alternatives namely option grant stock grant and do nothing multinomial logit results suggest that firms reprice options to increase sensitivity of pay to stock price and to temper down sensitivity of pay to volatility moreover repricing firms are younger and more concentrated in industries where human capital is important finally i find no evidence that internal governance or executive conflicts of interest are relevant in explaining repricing my results indicate that repricing is motivated by incentive alignment and retention and not by agency cost considerations

psychological factors and stock option exercise we investigate stock option exercise decisions by over 50 000 employees at seven corporations controlling for economic factors psychological factors influence exercise consistent with psychological models of beliefs employees exercise in response to stock price trends exercise is positively related to stock returns during the preceding month and negatively related to returns over longer horizons consistent with psychological models of values that include reference points employee exercise activity roughly doubles when the stock price exceeds the maximum price attained during the previous year

employee reload options pricing hedging and optimal exercise reload options call options granting new options on exercise are popularly used in compensation although the compound option feature may seem complicated there is a distribution free dominant policy of exercising reload options whenever they are in the money the optimal policy implies general formulas for numerical valuation simpler formulas for valuation and hedging follow from black scholes assumptions with or without continuous dividends time vesting affects the optimal policy but numerical results indicate that it is nearly optimal to exercise in the money whenever feasible the results suggest that reload options produce similar incentives as employee stock options and share grants the valuation of options in compensation schemes is important for several reasons valuations are needed for preparing accounting statements and tax returns and more generally for understanding what value has been promised to the employees and what residual value remains with the shareholders furthermore understanding the hedge ratios and the overall shape of the valuation function clarifies the employee s risk exposure and incentives this article studies the optimal exercise and valuation of a relatively new but increasingly commonplace type of employee stock option the reload option these options have attracted a fair amount of controversy we believe that in large part this controversy is due to a seemingly complex structure in the statement of financial accounting standards sfas 123 financial accounting standards board 1995 paragraph 186 concludes the board continues to believe that ideally the value of a reload option should be estimated on the grant date taking into account all of its features however at this time it is not feasible to do so on close examination however these options are in fact comparatively simple to analyze and understand moreover under black and scholes 1973 assumptions on the stock price we are able to provide explicit valuation and hedging formulas we hope our analysis helps to demystify reload options and permit a more focused debate

fear unemployment and pay flexibility the paper uses newly available cross section data to study wage determination in the united kingdom in the 1980s the main results are as follows 1 fear of unemployment substantially depresses pay 2 there is some evidence of a wage ratchet whereby rates of pay are more flexible upwards than downwards 3 the unemployment elasticity of pay averages 0 1 and 4 wages are much more flexible in nonunion workplaces than they are in union workplaces copyright 1991 by royal economic society

the repricing of executive stock options abstract we examine a sample of firms that reset the exercise prices on their executive options these repricings follow a period of about one year of poor firm specific performance in which the average firm loses one fourth of its value no other offsetting changes to option terms or compensation are made and many firms reprice more than once without repricing a majority of the options would have been at the money within two years we find that when faced with circumstances in which repricing might be chosen firms with greater agency problems smaller size and insider dominated boards are more likely to reprice

the innovative behavior of spanish enterprises and its impact on salaries our aim was to analyze the effects of firms innovative behavior on their employees salaries in the spanish manufacturing industry we found a premium in the wage paid by innovative firms regardless of size however when taking company size into account we found that the effect of innovations was greater in small medium enterprises sme contrary to what was expected the inferences of the models estimated suggest that the higher the market concentration the weaker the appropriability regime especially for smes however at the same time a firm s innovations reduce the impact of market concentration on wages making innovating firms more autonomous than non innovating ones even more to be able to innovate firms have to isolate their employees salaries from the product market these results hold regardless of firm s size but have a greater impact on the small medium group of firms finally our analysis backs the assumption that salaries in both large and small medium firms are generated by two distinct economic regimes supporting the proposition that an sme is not simply a scaled down large firm

has energy efficiency performance improved in china non energy sectors evidence from sequenced hybrid energy use tables we conduct a comparative analysis of two energy efficiency indicators for china heating value energy intensity hei and economic value energy intensity mei we formulate 1997 2002 2007 2012 hybrid energy comparable sequence use tables in an input output accounting framework and compare the two indicators using a randomized block anova the results show that meis and heis have significantly different variability patterns among sectors and are evolutionarily divergent over time the directional changes in mei and hei are found to be inconsistent at both the sectoral and national levels a further analysis with a lmdi index decomposition model shows that the difference between hei lmdi and hei lmdi is principally caused by energy prices based on the evidence from the two indicators and their relationship to energy prices we are unconvinced about china s purported improvements in energy efficiency in recent years

wages profits and capital intensity evidence from matched worker firm data swedish data on workers matched with firms balance sheet reports are used to examine the relation between wages and firms ability to pay results indicate that experienced and highly educated workers are sorted into profitable firms wages are positively correlated with profits and the capital labor ratio after controlling for worker quality degree of effort supervision job characteristics local unemployment firms employment history and employer size lester s range of pay due to rent sharing is around 12 24 of the mean wage in sweden which is close to the estimates for the united states and united kingdom

club convergence in carbon dioxide emissions we examine convergence in carbon dioxide emissions among 128 countries for the period 1960 2003 by means of a new methodology introduced by phillips and sul econometrica 75 6 1771 1855 2007a contrary to previous studies our approach allows us to examine for evidence of club convergence i e identify groups of countries that converge to different equilibria our results suggest convergence in per capita co2 emissions among all the countries under scrutiny in the early years of our sample however there seem to be two separate convergence clubs in the recent era that converge to different steady states interestingly we also find evidence of transitioning between the two convergence clubs suggesting either a slow convergence between the two clubs or a tendency for some countries to move from one convergence club to the other

firm profitability regional unemployment and human capital in wage determination this paper presents an analysis of wage formation in the norwegian private sector using data for individual workers matched with firm level information and regional unemployment a key issue is to test whether or not firm specific variables affect individual wages after controlling for individual specific factors and working conditions the results imply positive effects of firm specific profitability and firm size the elasticity of wages with respect to value added per worker and firm size is 5 and 3 3 respectively empirical evidence of a downward sloping regional wage curve is also reported while there is no support of the hypothesis of compensating wage differentials since data for three levels of aggregation are used the ols estimates of the standard errors are downward biased therefore results using a random effects model are also reported taking the multi level structure of the data into account

underlying causal factors of the european union energy intensity econometric evidence abstract the aim of the research is to determine the main factors that define the level of energy intensity in the countries of the european union the research was conducted by estimation of six baseline and six auxiliary regressions with and without time lags in form of one way fixed and random effects error component models on different unbalanced panel data samples covering the period 1995 2015 the obtained baseline regressions results generate three sets of findings the first set consists of extremely robust findings relating to the positive influence of gross fixed capital formation and industrial gross value added and negative effects of real per capita gross domestic product and oil products retail price these variables are statistically significant in all 36 baseline empirical models the second set of results consists of quite robust findings relating to insignificant influence of foreign direct investment and negative influence of coal price according to the results it cannot be confirm the hypothesis of energy saving technology transfer via foreign direct investments in european union member states the third set of results shows that the research has failed to generate any robust findings for economic openness import ratio urbanization and natural gas price which means that the effect of these determinants on energy intensity in european union member states is unspecified finally auxiliary regressions estimation results show that changes in the sectorial composition within the european union member states economies have not enhanced energy saving technological transfer via foreign direct investments

underwater options and the dynamics of executive pay to performance sensitivities we empirically analyze the dynamics of executives pay to performance sensitivities option pay to performance sensitivities become weaker as options fall underwater often leading to pressures to reprice options or restore pay to performance sensitivity in other ways building a detailed data set on executives portfolios of stock and options we find that the responsiveness of pay to performance sensitivities created by all executive holdings of stock and options to changes in stock price is large the elasticity of pay to performance sensitivities with respect to stock price decreases is about 0 7 and is larger for high option executives and for executives with high percentages of options already underwater the dominant mechanism through which companies offset declines in option pay to performance sensitivities is larger option grants following stock price declines on average these larger grants restore approximately 40 of the stock price induced pay to performance sensitivity declines option repricings are inconsequential in this regard despite the attention they have attracted in looking at positive returns we find the reverse higher returns both directly increase pay to performance sensitivities and lead to larger option grants which raise pay to performance sensitivities further thus option grants to executives tend to be largest following large stock price increases or large stock price decreases

long term changes in co2 emissions in austria and czechoslovakia identifying the drivers of environmental pressures this study presents fossil fuel related co2 emissions in austria and czechoslovakia current czech republic and slovakia for 1830 2000 the drivers of co2 emissions are discussed by investigating the variables of the standard kaya identity for 1920 2000 and conducting a comparative index decomposition analysis proxy data on industrial production and household consumption are analysed to understand the role of the economic structure co2 emissions increased in both countries in the long run czechoslovakia was a stronger emitter of co2 throughout the time period but per capita emissions significantly differed only after world war i when czechoslovakia and austria became independent the difference in co2 emissions increased until the mid 1980s the period of communism in czechoslovakia explained by the energy intensity and the composition effects and higher industrial production in czechoslovakia counterbalancing factors were the income effect and household consumption after the velvet revolution in 1990 czechoslovak co2 emissions decreased and the energy composition effect and industrial production lost importance despite their different political and economic development austria and czechoslovakia reached similar levels of per capita co2 emissions in the late 20th century neither austrian eco efficiency nor czechoslovak restructuring have been effective in reducing co2 emissions to a sustainable level

where are the industrial technologies in energy economy models an innovative cge approach for steel production in germany top down computable general equilibrium cge models are used extensively for analysis of energy and climate policies energy intensive industries are usually represented in top down economic models as abstract economic production functions commonly of the constant elasticity of substitution ces or translog functional form this study explores methods for improving the realism of energy intensive industries in top down economic models we replace a ces production function with a set of specific technologies and provide a comparison between the traditional production function approach in cge models and an approach with separate technologies for making iron and steel in particular we investigate the response of the iron and steel sector to a set of co2 price scenarios our technology based integrated approach permits a choice between several technologies for producing iron and steel and allows for shifts in technology characteristics over time towards best practice innovative technologies in addition the general equilibrium framework allows us to analyze interactions between production sectors for example between electricity generation and iron and steel production investigate simultaneous economy wide reactions and capture the main driving forces of greenhouse gas emissions reductions under a climate policy we conclude that technology specific effects are crucial for the economic assessment of climate policies in particular the effects relating to process shifts and fuel input structure

policies for eliminating low efficiency production capacities and improving energy efficiency of energy intensive industries in china abstract china faced the greatest challenge in balancing its economic growth energy and resource security as well as environmental pollution the energy intensive industries which used to be the major force driving china s economic growth had seriously exhausted the countries natural resources and energy and at the same time polluted the environment because of the severe surplus of low efficiency production capacities as a result the chinese government had initiated multiple economic and administrative policies to eliminate these low efficiency production capacities intended to improve the energy efficiency of energy intensive industries these policies are summarized in this paper along with export tax rebating rate resource tax administrative audit and approvals differential electric power pricing and shutting down the low efficiency production capacities the paper also evaluates the effects of these policies by analyzing several key indicators about the energy intensive industries including fixed asset investment growth rate energy intensity of industrial added value waste gas emission intensity of industrial added value the valdex methodology is selected to examine the improving trends of energy efficiency for energy intensive industries the analyzing results show that firstly the development of low efficiency capacities tends to be more sensitive to the policies so the policies that china had enacted really exert very important effects on improving the energy efficiency of energy intensive industries however the effects of economic policies seem more faster and obvious than the fiscal policies besides the results also show that polices which are designed to reserve energy may not necessarily exert the same effects on reducing emissions there is still large room for improving the energy efficiency of energy intensive industries substantial improvement still needs to be done for current policies system some suggestions for future work are provided

insider forces in wage determination new evidence for norwegian industries using panel data for norwegian industries we establish a significant permanent relation between industry wages and industry profitability the estimated long run insider weight is above 0 2 and stable both over time and across industries industry wages are significantly affected by aggregate unemployment and the preferred wage equation implies a highly convex wage curve

union wage differentials product market influences and the division of rents this paper examines the extent to which product market conditions limit the ability of trade unions to establish wage differentials over nonunion pay the mean union pay differential is estimated to be of the order of 8 percent to 10 percent in establishments with some degree of product market power but zero in establishments facing competitive product market conditions when competitive conditions are faced a preentry closed shop and high union coverage of the industry are both required it is estimated that only 5 percent of the establishments in which there are significant differentials over nonunion pay face generally competitive product market conditions copyright 1990 by royal economic society

decomposition of co2 emissions change from energy consumption in brazil challenges and policy implications this study evaluates the changes in co2 emissions from energy consumption in brazil for the period 1970 2009 emissions are decomposed into production and consumption activities allowing computing the full set of energy sources consumed in the country this study aims to develop a comprehensive and updated picture of the underlying determinants of emissions change from energy consumption in brazil along the last four decades including for the first time the recently released data for 2009 results demonstrate that economic activity and demographic pressure are the leading forces explaining emission increase on the other hand carbon intensity reductions and diversification of energy mix towards cleaner sources are the main factors contributing to emission mitigation which are also the driving factors responsible for the observed decoupling between co2 emissions and economic growth after 2004 the cyclical patterns of energy intensity and economy structure are associated to both increments and mitigation on total emission change depending on the interval the evidences demonstrate that brazilian efforts to reduce emissions are concentrated on energy mix diversification and carbon intensity control while technology intensive alternatives like energy intensity has not demonstrated relevant progress residential sector displays a marginal weight in the total emission change

comparing structural decomposition analysis and index to analyze and understand historical changes in economic environmental employment or other socio economic indicators it is useful to assess the driving forces or determinants that underlie these changes two techniques for decomposing indicator changes at the sector level are structural decomposition analysis sda and index decomposition analysis ida for example sda and ida have been used to analyze changes in indicators such as energy use co2 emissions labor demand and value added the changes in these variables are decomposed into determinants such as technological demand and structural effects sda uses information from input output tables while ida uses aggregate data at the sector level the two methods have developed quite independently which has resulted in each method being characterized by specific unique techniques and approaches this paper has three aims first the similarities and differences between the two approaches are summarized second the possibility of transferring specific techniques and indices is explored finally a numerical example is used to illustrate differences between the two approaches

altering the terms of executive stock options abstract we examine the practice of resetting the terms of previously issued executive stock options we identify properties of reset options develop a model for valuing resettable options and characterize the firms that have reset options we find the vast majority of options are reset at the money resulting on average in the strike price dropping 40 our valuation model suggests that resetting has only a small impact on the ex ante value of an option award but the ex post gain can be substantial finally we find resetting has a strong negative relation with firm performance even after correcting for industry performance

decomposition of electricity demand in china s industrial sector in the past five years china s demand for electricity has accelerated far beyond what central planners had forecasted leading to supply constraints and costly brownouts throughout the country this paper presents analysis of the effect of changes in the industrial sector on electricity demand an important economic sector contributing to these above patterns as it consumes nearly 70 of the electricity generated in china using decomposition analysis it is found that both increased industrial activity and fuel shifts helped increase industrial sector electricity demand between 1998 and 2002 the period of focus in this study but significant increases in energy efficiency countered this

sticks or carrots optimal ceo compensation when managers are loss averse this paper analyzes optimal executive compensation contracts when managers are loss averse we calibrate a stylized principal agent model to the observed contracts of 595 ceos and show that this model can explain observed option holdings and high base salaries remarkably well for a range of parameterizations we also derive and calibrate the general shape of the optimal contract that is increasing and convex for medium and high outcomes and that drops discontinuously to the lowest possible payout for low outcomes finally we identify the critical features of the loss aversion model that render optimal contracts convex

electricity intensities of the oecd and south africa a comparison abstract this paper investigates the relationship between south africa s total electricity intensity and that of the oecd members a very important trade block these results will assist in ascertaining possible scope for improvement if such exists this is necessary as electricity is an essential input for production and hence it affects the competitiveness of the country calculating the electricity intensities defined as the ratio of electricity consumption to total output we found that south africa s electricity intensity has more than doubled between 1990 and 2007 all the oecd members excluding iceland weighted growth in electricity intensity was lower than that of south africa by a considerable margin the sectoral analysis showed that the majority of the south african sectors are more electricity intensive to improve its industrial competitiveness and as an additional benefit contribute towards achieving its stated commitments towards reduction of greenhouse gas emissions south africa will have to improve its total and sectoral electricity efficiency levels that not only were higher but also increasing at an alarming rate

nontraded asset valuation with portfolio constraints a binomial approach we provide a simple binomial framework to value american style derivatives subject to trading restrictions the optimal investment of liquid wealth is solved simultaneously with the early exercise decision of the nontraded derivative noshort sales constraints on the underlying asset manifest themselves in the form of an implicit dividend yield in the risk neutralized process for the underlying asset one consequence is that american call options may be optimally exercised prior to maturity even when the underlying asset pays no dividends applications to executive stock options eso are presented it is shown that the value of an eso could be substantially lower than that computed using the black scholes model we also analyze nontraded payoffs based on a price that is imperfectly correlated with the price of a traded asset the economics of asset pricing when one or more of the assets in the opportunity set are either subject to trading restrictions or entirely nontraded is a matter of great interest viewed from a practical perspective we have several important examples of such assets that are subject to trading restrictions pensions which represent perhaps the most significant of assets held by individual households are subject to trading restrictions it is typically the case that assets in pensions are not available for immediate consumption borrowing against pension assets is subject to significant direct and indirect costs by way of taxes and early withdrawal penalties human capital is another example housing investment is also illiquid and subject to significant transaction costs together pensions human capital and housing constitute a substantial part of a typical household s assets the significance of such nontraded assets for risk premia has already been noted by bewley 1982 there are other circumstances where lack of unrestricted trading plays an important role executive compensation plans usually take the this article was presented at boston university we would like to thank the editor bernard dumas and two anonymous referees for very helpful comments we also thank nalin kulatilaka and seminar participants for useful suggestions ganlin chang fei guan and carlton osakwe provided valuable research assistance j detemple acknowledges support from the social sciences and humanities research

the triptych approach revisited a staged sectoral approach for climate mitigation abstract the triptych approach is a method for allocating future greenhouse gas ghg emission reductions among countries under a post 2012 international climate mitigation regime based on technological criteria at the sector level and accounting for structural differences the emission allowances are decomposed according to sectors thereby enabling the link to real world emission reduction strategies to be more concrete the new triptych approach presented here is a refinement of an earlier version in terms of an increased transparency and allowing a delayed participation for developing countries initial participation of developing countries with incentives but no penalties through no lose targets or sustainable development policies and measures for this article we calculated the emission reductions for countries for two technology oriented scenarios which stabilize ghg concentrations at 450 and 550 ppm co 2 eq respectively the reductions are ambitious but nonetheless compatible with existing technical reduction potentials as growth is allowed but efficiency has to be improved

microdata evidence on rent sharing we examine the effect of firm profits on wages for individual workers while focusing on the empirical complications associated with estimating the extent of rent sharing controlling for worker and firm fixed effects and using several instruments to deal with the endogeneity of profits we report results indicating that ordinary least square ols estimates strongly underestimate the effects of profits on wages moreover the effect of profits on wages are estimated separately for firms with increasing and decreasing profits within a given time period we find a positive and stable effect only in firms with increasing profits this is in line with the idea that falling profits do not lead to wage cuts while increasing profits imply higher wages

the other side of the trade off the impact of risk on executive compensation the principal agent model of executive compensation is of central importance to the modern theory of the firm and corporate governance yet the exiting empirical evidence supporting it is quite wea

the effect of competition on wages and productivity evidence from the united kingdom abstract i examine the impact of competition on wages and productivity using a panel data set of u k manufacturing industries over 1954 1973 the introduction of cartel law in the united kingdom in the late 1950s caused an intensification of price competition in previously cartelized manufacturing industries but it did not affect those industries that were not cartelized the econometric results from a comparison of the two groups of industries before and after the introduction of cartel law provide strong evidence of a negative effect of collusion on labor productivity growth there is no evidence of any effect of collusion on wages these results are robust to controlling for the potential endogeneity of collusion and are further strengthened by a comparison with u s data

you can pay me now and you can pay me later the dynamic response of executive compensation to firm performance empirical studies estimating the impact of firm performance on executive pay have primarily concentrated on the short run response in this study the authors present estimates of the complete dynamic response of ceo pay to firm performance they find that the cumulative response of pay to performance is roughly ten times that of the contemporaneous response a onetime innovation in firm performance typically raises pay over the next 4 5 years and compensation arrangements have shifted toward greater performance sensitivity and longer term pay arrangements over the four decades studied copyright 1995 by university of chicago press

the exercise and valuation of executive stock options abstract in theory hedging restrictions faced by managers make executive stock options more difficult to value than ordinary options because they imply that exercise policies of managers depend on their preferences and endowments using data on option exercises from 40 firms this paper shows that a simple extension of the ordinary american option model which introduces random exogenous exercise and forfeiture predicts actual exercise times and payoffs just as well as an elaborate utility maximizing model that explicitly accounts for the nontransferability of options the simpler model could therefore be more useful than the preference based model for valuing executive options in practice

the consequences of the fasb s 1998 proposal on accounting for stock option repricing abstract we examine repricing activity surrounding the fasb s 1998 announcement regarding accounting for repriced options we find that repricing increases during and decreases after the 12 day window between the announcement and proposed effective dates consistent with firms timing repricings to avoid recording an expense we find that firms experiencing increasing earnings patterns firms with earnings around zero and growth firms are more likely to reprice in the window but having repriced recently decreases the likelihood of doing so the evidence suggests that firms trade off financial reporting benefits against reputation costs in decisions to time repricings to get favorable accounting treatment

shareholder wealth and wages evidence for white collar workers we present empirical evidence on the relationship between individual wages conditional on worker characteristics and equity returns using a unique survey from the bureau of labor statistics equity returns affect the wages only of workers with three or more years of tenure a 4 percent increase in a firm s market value raises pay by 0 3 percent within three years our estimates suggest that each 10 increase in shareholder wealth raises the present value of a firm s wage bill by 1 the elasticity of white collar wages with respect to equity returns is one third smaller than the ceo salary elasticities in our sample

using logarithmic mean divisia index to analyze changes in energy use and carbon dioxide emissions in mexico s iron and steel industry using international comparisons and log mean divisia index this paper analyzes energy and co2 emission trends of mexico s iron and steel industry during the period 1970 2006 examining co2 emissions related to energy use and production process the decomposition analysis is based on the structure efficiency analysis for international comparisons considering industrial structure and the best available technology results show that for the period 1970 2006 activity drove up primary energy use by 227 instead of the actual 133 while structure and efficiency effects drove it down by 5 and by 90 respectively the important improvement in mexican iron and steel primary energy efficiency reduced the gap between best international practice and actual primary energy consumption from 103 in 1970 to only 15 in 2006 co2 emissions from fuel consumption and production process increased by 134 and in addition to structure and efficiency fuel share effect also drove down emissions by 4 2 in the entire period

structural decompositions of energy consumption between 1995 and 2009 evidence from wiod abstract energy is key to achieving sustainable development this paper explicitly distinguishes between the supply side of energy consumption and demand side of energy consumption and investigates the factors that affect the energy consumption across economies using data from the world input output database wiod this paper decomposes the relative changes of energy consumption into intensity effect production structure structural change in final demand total final demand effect and household consumption then it further decomposes production structure into inter industry structural effect and trade effect in intermediate inputs overall energy consumption growth is mainly driven by total final demand 55 04 increase at the world level but can be significantly reduced by intensity effect due to technological change 21 02 decrease at the world level there is heterogeneity of structure related effects across economies and within the same economy in both aspects of energy consumption in addition the trade effect and household effect are relatively small this paper provides an empirical framework for analyzing energy consumption in a globalizing world and suggests tailored and integrated energy policies

the use of physical indicators for industrial energy demand scenarios abstract scientific information on the size and nature of the threat of climate change is needed by politicians in order to weight their decisions computerised models are extremely useful tools to quantify the long term effects of current policies this paper describes a new modelling approach that allows formulation of industrial energy demand projections consistent with the assumptions for scenario drivers such as gdp and population in the model a level of industrial production is used as a key variable and we define it in physical units rather than in monetary units the aim of this research is to increase insights that come with long term energy demand scenarios this research clearly shows that physical indicators provide additional insights in scenario analysis the use of physical indicators instead of monetary indicators seems to affect the energy scenarios significantly the differences with monetary indicators are larger in developing regions than in oecd regions we conclude that an integrated energy and materials approach reveals developments that are hardly visible using a monetary approach moreover this research shows the potential and benefits of the use of physical indicators for scenario development

why do firms use incentives that have no incentive effects this paper illustrates why firms might choose to implement stock option plans or other pay instruments that reward luck i consider a model where adjusting compensation contracts is costly and where employees outside opportunities are correlated with their firms performance the model may help to explain the use and recent rise of broad based stock option plans as well as other financial instruments even when these pay plans have no effect on employees on the job behavior the model suggests that agency theory s often overlooked participation constraint may be an important determinant of some common compensation schemes particularly for employees below the highest executive ranks many compensation plans reward or punish employees for factors they cannot control an often discussed example of this phenomenon is executive compensation where stock options are not generally indexed to the overall market however many firms also offer firm wide stock options and profit sharing plans that provide even weaker incentives than executive plans after all most workers can expect to reap trivial personal gain from their contribution to firm value or profits i consider an explanation for this phenomenon in which firms contract with employees as a means of indexing wages to market rates rather than to provide incentives while much of the agency literature has concentrated on inducing optimal effort i consider the importance of the generally overlooked participation constraint i study a model in which employees outside opportunities are correlated with firm profits or stock price and in which both turnover and adjusting the pay scheme parameters are costly given these assumptions the firm may find it most profitable to pay the employee in a way that is correlated with the outside options presented by the outside labor market despite the requisite risk premium rather than pay a fixed wage that insures participation in all states the model derived below starts from the assumption that wage adjustments are costly but that workers are willing to make part of their pay contingent

wages and product market power this paper analyses time series on some 800 british manufacturing companies to address various questions concerning the role of insiders and market power in wage determination the following are the most important results first product market power has a positive impact on wages this impact is enhanced in large firms but is not influenced by union status second while firm specific factors influence wages the size of these effects is not influenced by union status firm size or product market power however product market power reduces the generally strong negative effect of unemployment on wages finally there is no robust evidence of insider power at work in wage setting irrespective of product market position

optimal exercise prices for executive stock options although exercise prices for executive stock options can be set either below or above the grant date market price in practice virtually all options are granted at the money we offer an economic rationale for this apparent puzzle by showing that pay to performance incentives for risk averse undiversified executives are typically maximized by setting exercise prices at or near the grant date market price we provide an operationally useful alternative to black scholes 1973 for the purpose of both valuing executive stock options and measuring the incentives created by options our framework has implications not only for exercise price policies but also for indexed options option repricings exchanges of cash for stock based compensation and the design of bonus plans

are ceos really paid like bureaucrats a common view is that there is little correlation between firm performance and ceo pay using a new fifteen year panel data set of ceos in the largest publicly traded u s companies we document a strong relationship between firm performance and ceo compensation this relationship is generated almost entirely by changes in the value of ceo holdings of stock and stock options in addition we show that both the level of ceo compensation and the sensitivity of compensation to firm performance have risen dramatically since 1980 largely because of increases in stock option grants

insider forces and wage determination this paper investigates the relative importance of firm specific factors i e insider forces in wage determination using firm level data on 219 u k companies over 1974 82 it finds that a 1 percent rise in a firm s prices or productivity relative to the aggregate economy leads to a rise in relative wages of 0 1 0 2 percent as a corollary to this outside factors like the aggregate wage and the unemployment rate also play an important role there is evidence for insider based hysteresis effects but these are inversely related to the extent to which firms take national agreements into account copyright 1990 by royal economic society

asymmetric sensitivity of ceo cash compensation to stock returns abstract we document that ceo cash compensation is twice as sensitive to negative stock returns as it is to positive stock returns since stock returns include both unrealized gains and unrealized losses we expect cash compensation to be less sensitive to stock returns when returns contain unrealized gains positive returns than when returns contain unrealized losses negative returns this is consistent with boards of directors exercising discretion to reduce costly ex post settling up in cash compensation paid to ceos

do indicators have politics a review of the use of energy and carbon intensity indicators in public debates abstract in this paper we analyse how energy and carbon intensity indicators which have huge popularity among policy makers are framed in the discourse of think tanks consulting groups and other stakeholders what emerges from the analysis of public documents reports and policy briefs is that intensity indicators are often framed uncritically and unreflectively our analysis highlights three fundamental themes that emerge from public debates around intensity indicator first efficiency and intensity often framed in terms of productivity are used equivalently second intensity is perceived as a measure of win win sustainability in which economic growth can be decoupled from energy consumption without a substantial restructuring of the productive system third the analysis suggests that energy and carbon intensity indicators are attractive for policy makers especially in the so called developing world because they can be used to design political targets e g paris agreement without questioning the right to economic growth of powerful emerging economies like the brics the paper shows the strong limitations of intensity indicators and their potential do misguide policymakers

stock based pay in new economy firms abstract ittner lambert and larcker j accounting economics 2003 this issue present compelling evidence that new economy firms rely more on stock based compensation than do old economy firms based on 1998 and 1999 data from a proprietary sample of companies i complement the ill results by analyzing data over a longer time period 1992 2001 and more importantly document the effect of the 2000 market crash on stock based pay in new economy firms finally i offer evidence supporting the conjecture that differences in pay practices between new and old economy firms reflect accounting considerations perceived costs and competitive inertia

research on the energy saving effect of energy policies in china 1982 2006 this paper summarizes the main energy policies of china from 1980 and divides them into three groups of policies two methods with and without antitheses and linear regression are created to evaluate the energy saving effects of the energy policies and the energy saving effects of these three groups of energy policies of china are evaluated by the two methods respectively it is concluded that with and without antitheses is used to evaluate short term effects and linear regression is used to evaluate long term effects

energy intensity in the iron and steel industry a comparison of physical and economic indicators abstract energy consumption of the iron and steel industry is examined in seven countries brazil china france germany japan poland and the united states for the period 1980 1991 using a decomposition analysis based on physical indicators for process type and product mix we decompose intra sectoral structural changes and efficiency improvements specific energy consumption decreased in all countries except poland efficiency improvement played a key role in brazil china germany and the us while structural changes were the main driver for energy savings in france and japan we also compare the use of various economic indicators to physical indicators and find that they do not track physical developments well in poland or the developing countries we studied in the industrialized countries value added based energy intensity indicators generally reflect the specific energy consumption better than other economic indicators although large differences occur in individual years we found a smaller correlation between other economic indicators gross output and value of shipments and specific energy consumption we conclude that use of physical energy intensity indicators improves comparability between countries provides greater information for policy makers regarding intra sectoral structural changes and provides detailed explanations for observed changes in energy intensity

on the optimality of resetting executive stock options the practice of resetting strike prices on underwater executive stock options has drawn criticism for weakening managerial incentives our model shows that although the anticipation of resetting can negatively affect initial incentives resetting can still be an important value enhancing aspect of compensation contracts even from an ex ante standpoint in fact we find that some resetting is almost always optimal the relative advantages of resetting diminish with greater ability of managers to influence the resetting process greater relative importance of external factors on stock performance and lower costs of replacing incumbent managers

employee stock option exercises an empirical analysis this paper describes the exercise behavior of over 50 000 employees who hold longterm options on employer stock at eight corporations employees typically exercise options years before expiration commonly sacrificing half of the black scholes value exercise is strongly associated with recent stock price movements the market to strike ratio proximity to vesting dates time to maturity volatility and the employee s level within the company these findings have implications for compensation planners the fasb as it develops a new accounting standard for options and financial statement users and preparers who apply and interpret the new fasb standard

decomposition of aggregate energy intensity changes in two measures ratio and difference decomposition analysis has been popular in energy demand analysis and has been found useful in policy related studies past studies include decomposition of changes of an aggregate indicator measured in terms of either ratios or differences into several pre defined contributing factors aggregate indicators that are often studied include total national energy demand energy demand in specific consuming sectors aggregate energy intensity and energy related carbon dioxide emissions however the possible linkages between the ratio measure and the difference measure including their decomposition results have seldom been analysed this paper examines this issue using the divisia decomposition technique and a unique pair of decomposition formulae numerical examples based on singapore and taiwan industrial electricity demand data are presented

analysis and decomposition of energy consumption in the chilean industry abstract with rising energy costs and climate change concerns energy efficiency will be important in maintaining competitiveness and reducing the environmental impact of industrial activities in this paper we study the chilean industrial sector which is the largest consumer of energy within the country energy demand and co 2 emissions in chile have grown rapidly in recent years while energy supply is mostly imported and subject to disruption therefore it is important to understand energy consumption in this sector and determine which sub sectors have the greatest potential to reduce energy consumption we used the index decomposition analysis ida applying the logarithmic mean divisia index method i lmdi i to quantify the impact of diverse driving factors on energy consumption furthermore a panel data analysis was used to determine whether there are differences in energy intensity across firms with different characteristics our results show that energy intensity has risen over time although energy consumption remains stable this fact supports the idea that energy efficiency policies could play an important role for the industrial sector additionally energy consumption and energy intensity follow different patterns in each sub sector therefore we conclude that the application of differentiated sectoral policies is preferable over a single global policy

the original management incentive schemes during the 1990s the structure of pay for top corporate executives shifted markedly as the use of stock options greatly expanded by the early 2000s as the dot com boom ended and the nasdaq stock index melted down these modern executive incentive schemes were being sharply questioned on many grounds for encouraging excessive risk taking and a short run orientation for being an overly costly and inefficient method of providing incentives and even for tempting managers of firms like enron worldcom and tyco to commit fraud in order to ensure a high stock price at the time of exercise this article examines executive incentive schemes developed by du pont and general motors in the 1920s the original incentive schemes linking executive compensation to stock prices the author argues that these plans were well designed to pre empt and address many of the criticisms of modern day executive stock option plans

consistent multi level energy efficiency indicators and their policy implications in order to cope with the global warming issue most of the asia pacific economic cooperation apec economies have made energy conservation policy a top priority in terms of their energy policies the energy efficiency indicators included in the present paper focus on the micro foundation aspects there are basically two types of energy efficiency indicators namely the economic thermodynamic energy efficiency indicators that use real gdp as the denominator and the physical thermodynamic energy efficiency indicators that are based on the output volume index while the common definitions and consistent methodology used in the present paper fulfill the iea pyramid eei concept the new methodology in this paper compares the decomposition effects between upstream and downstream industries when aggregating efficiency changes these decomposition effects can thereby provide valuable explanations for the energy conservation policy needed by energy policy and government administrators

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

the uk capital stock new estimates of premature scrapping in recent years there has been a considerable degree of interest in the measurement of the capital stock with special reference to the degree of premature scrapping of capital equipment that might have occurred it has been argued that this might be one reason for the observed slowdown in productivity growth see e g muellbauer 1984 or baily 1981 others have alleged that there has been a large decrease in manufacturing capacity in the uk since 1980 and that therefore we should not reflate the economy see e g ball 1985 for we run the risk of re igniting inflation the latter view is commonly expressed in the press both by financial commentators and politi cians it is therefore of some importance to assess the extent to which the official stock meas ures are misleading

environment adjusted total factor energy efficiency of taiwan s service sectors this study computes the pure technical efficiency pte and energy saving target of taiwan s service sectors during 2001 2008 by using the input oriented data envelopment analysis dea approach with the assumption of a variable returns to scale vrs situation this paper further investigates the effects of industry characteristics on the energy saving target by applying the four stage dea proposed by fried et al 1999 we also calculate the pre adjusted and environment adjusted total factor energy efficiency tfee scores in these service sectors there are three inputs labor capital stock and energy consumption and a single output real gdp in the dea model the most energy efficient service sector is finance insurance and real estate which has an average tfee of 0 994 and an environment adjusted tfee eatfee of 0 807 the study utilizes the panel data random effects tobit regression model with the energy saving target est as the dependent variable those service industries with a larger gdp output have greater excess use of energy the capital labor ratio has a significantly positive effect while the time trend variable has a significantly negative impact on the est suggesting that future new capital investment should also be accompanied with energy saving technology in the service sectors

endogenous costs and price cost margins an application to the european airline industry this paper allows for endogenous costs in the estimation of price cost margins in particular we estimate price cost margins when firms bargain over wages we extent the standard two equation set up demand and first order condition in the product market to include a third equation which is derived from bargaining over wages in this way price cost margins are determined by wages and vice versa we implement the model using data for eight european airlines from 1976 1994 and show that the treatment of endogenous costs has important implications for the measurement of price cost margins and the assessment of market power our main result is that observed prices in europe are virtually identical to monopoly prices even though observed margins are consistent with nash behavior apparently costs had been inflated to the point that the european consumers were faced with a de facto monopoly prices

disaggregated analysis of us energy consumption in the 1990s evidence of the effects of the internet and rapid economic growth abstract this paper decomposes us energy use from 1988 to 1998 and attributes the changes in energy use to three underlying factors activity structure and intensity for this study we use a bottom up methodology by separately decomposing delivered energy use in six sectors travel freight manufacturing industries non manufacturing industries residential and services the most commonly used indicator of energy efficiency in the total economy the ratio of energy consumed to unit of gdp e gdp created can often be misleading the rapid decline in the e gdp ratio in recent years has been used to support assertions that the internet and information technologies in general have enabled improvements in energy efficiencies however our disaggregate analysis suggests that energy intensities on average are falling more slowly than ever before while actual energy use increased faster than at any time since 1970 the decline in the e gdp ratio in the mid to late 1990s owes much more to structural changes in the demand for energy services than to falling energy intensities

evaluating the interplays among economic growth and energy consumption and co2 emission of china during 1990 2007 the interplays among economy and energy and environment have been widely concerned this paper put forward several indicators to quantify the relationships among economic growth and energy consumption and co2 emission as an example these indicators were applied to evaluate the comprehensive performances of china during 1990 2007 the results show that chinese people has been living a better life with chinese rapid economic growth but not synchronously in urban and rural areas non carbon energy resources share has increased however fossil energy resources have still acted as the main driver for chinese economic growth during this period technical progress has improved the fossil energy efficiency of chinese economic activity which leads to co2 emission per unit gdp and co2 emission per capita unit gdp dropping simultaneously however the two indicators annual decline rates become smaller and smaller which reflects that technical progress role is dropping and economic scale s effect is climbing people s survival has a rising contribution to co2 emission co2 emission per capita has increased which shows that economic scale has greater impact on co2 emission than technical progress does relatively speaking chinese development patterns have become more and more sustainable during this period finally based on the related issues being discussed some corresponding suggestions are put forward for chinese government to further coordinate the relationship among economic development and energy consumption and co2 emission the proposed indicators can form a set of useful tool for policy makers to promote the harmonious development of economy and energy and environment in different regions and countries

introducing convexity into optimal compensation contracts abstract we study when it is appropriate to add a convex component such as stock options to an optimal managerial compensation contract we show that convexity is introduced when managers have moderate levels of relative risk aversion and decreasing absolute risk aversion in addition we study how convexity is affected as the distribution of outcomes becomes more skewed toward low outcomes here we show that while convexity increases when skewness is increased without regard to the effect on mean stock price the opposite effect results when increases in skewness leave the mean stock price unchanged

information based stock trading executive incentives and the principal agent problem we examine the role of information based stock trading in affecting the risk incentive relation by incorporating an endogenous informed trading into an optimal incentive contracting model we analytically show that apart from reducing incentives a greater risk increases the level of information based trading which consequently enhances executive incentives and offsets the negative risk incentive relation we calibrate the model and find that the economic magnitude of this incentive enhancement effect is significant our empirical test using real world executive compensation data lends strong support to the model prediction our results suggest that principals boards of directors should consider underlying stock trading characteristics when structuring executive incentives

power to change analysis of household participation in a renewable energy and energy efficiency programme in central australia the australian government funded a national solar city program 2008 2013 to support communities to increase adoption of energy efficiency measures and renewable energy technology one community was alice springs a town with about 9000 households in the geographic centre of australia the programme offered a package of support free energy audits discounts for the purchase of renewable energy technology and energy efficiency measures and ongoing information households that adopted solar hot water and photovoltaic systems reduced their electricity usage immediately after adoption by 10 and 34 respectively and this was maintained in the long term a small rebound effect of 15 was observed in the photovoltaic adopters it was observed that on average households that adopted only energy efficiency measures did not have a significant reduction in their electricity usage over the long term however consistent with expectations this study did show that there was a significant correlation between the number of energy efficiency measures adopted and the greatest household reduction in electricity usage these contrary results indicate that there are additional factors involved the connection between the effective use of measures coincident behavioural change or increased energy awareness and greater energy reduction is discussed

ceo incentives and firm size we develop a model that clarifies how to measure ceo incentive strength and how to reconcile the enormous differences in pay sensitivities between executives in large and small firms the crucial parameter is shown to be the elasticity of ceo productivity with respect to firm size we find that ceo marginal products rise significantly with firm size confirming rosen s conjecture that ceos of large firms have a chain letter effect on firm performance and overall ceo incentives are roughly constant or decline slightly with firm size we employ a multitask model to discuss implications for the design of control systems

manufacturing energy use in eight oecd countries decomposing the impacts of changes in output industry structure and energy intensity this paper examines trends in manufacturing energy use in eight oecd countries decomposing the changes that occured between 1973 and 1987 into the effects of changes in aggregate manufacturing activity industry structure and energy intensities measured at the industry group level while manufacturing production grew in every country except the uk the rate of growth was variable from nation to nation structural change led to modest reductions in energy use in most countries although in norway structural change led to substantial growth in energy use the reduction in energy intensities was strikingly uniform across all nations ranging from 20 norway to 36 japan over the period of the analysis while other studies have used divisia decomposition techniques we use an alternative method based on laspeyres indices a comparison of the two techniques shows that they yield closely similar empirical results although the laspeyres approach is more easily interpreted while the interactions between changes in structure and intensity are arbitrarily assigned to the two factors by the divisia approach the lapeyres method yields interaction terms that explicitly account for such effects

energy saving and energy efficiency concepts for policy making departing from the concept of rational use of energy the paper outlines the microeconomics of end use energy saving as a result of frugality or efficiency measures frugality refers to the behaviour that is aimed at energy conservation and with efficiency we refer to the technical ratio between energy input and output services that can be modified with technical improvements e g technology substitution changing behaviour from one side and technology from the other are key issues for public energy policy in this paper we attempt to identify the effects of parameters that determine energy saving behaviour with the use of the microeconomic theory the role of these parameters is crucial and can determine the outcome of energy efficiency policies therefore policymakers should properly address them when designing policies

executive compensation a modern primer this article studies traditional and modern theories of executive compensation bringing them together under a simple unifying framework accessible to the general interest reader we analyze assignment models of the level of pay and static and dynamic moral hazard models of incentives and compare their predictions to empirical findings we make two broad points first traditional theories find it difficult to explain the data suggesting that compensation results from rent extraction by ceos however more modern shareholder value theories that arguably better capture the ceo setting do deliver predictions consistent with observed practices suggesting that these practices need not be inefficient second seemingly innocuous features of the modeling setup often made for tractability or convenience can lead to significant differences in the model s implications and conclusions on the efficiency of observed practices we close by highlighting apparent inefficiencies in executive compensation and additional directions for future research
