demand response from the non domestic sector early uk experiences and future opportunities abstract demand response is believed by some to become a major contributor towards system balancing in future electricity networks shifting or reducing demand at critical moments can reduce the need for generation capacity help with the integration of renewables support more efficient system operation and thereby potentially lead to cost and carbon reductions for the entire energy system in this paper we review the nature of the response resource of consumers from different non domestic sectors in the uk based on extensive half hourly demand profiles and observed demand responses we further explore the potential to increase the demand response capacity through changes in the regulatory and market environment the analysis suggests that present demand response measures tend to stimulate stand by generation capacity in preference to load shifting and we propose that extended response times may favour load based demand response especially in sectors with significant thermal loads

historical review of demand side management in china management content operation mode results assessment and relative incentives abstract traditional power load management in china is featured by power rationing without considering user demand however since the 1990s demand side management dsm has been introduced by local governments and enterprises in china to improve terminal power efficiency and optimize resources allocation and certain breakthrough have already been achieved demand response aims at improving the energy efficiency of end users and achieving emission reduction targets based on the development status of power industry and electricity market in china this paper firstly reviews the three key development stages of traditional dsm including management content operation mode and results assessment secondly this paper analyzes the demand side management aimed at energy conservation and emissions reduction selecting the core elements and key processes influencing terminal power efficiency of dsm development in addition dsm safeguard system and incentive mechanism including political economic technical and managerial measures are further discussed to achieve the aim of energy conservation and emission reduction finally this paper systematically analyzes related policies and regulations proposed by the government and put forward relative policy recommendations for dsm development in china

measuring the financial impact of demand response for electricity retailers abstract due to the integration of intermittent resources of power generation such as wind and solar the amount of supplied electricity will exhibit unprecedented fluctuations electricity retailers can partially meet the challenge of matching demand and volatile supply by shifting power demand according to the fluctuating supply side the necessary technology infrastructure such as advanced metering infrastructures for this so called demand response dr has advanced however little is known about the economic dimension and further effort is strongly needed to realistically quantify the financial impact to succeed in this goal we derive an optimization problem that minimizes procurement costs of an electricity retailer in order to control demand response usage the evaluation with historic data shows that cost volatility can be reduced by 7 74 peak costs drop by 14 35 and expenditures of retailers can be significantly decreased by 3 52

residential peak electricity demand response highlights of some behavioural issues electricity demand response refers to consumer actions that change the utility load profile in a way that reduces costs or improves grid security the focus of demand response has mainly been on the commercial and big industrial sectors because of the large demand reduction that they can offer to the utility grid operators utilities are showing increasing interest in residential demand response rdr rdr can be treated as an energy resource which can be assessed and commercially developed however there are still some issues that remain to be addressed for rdr to be successful these include price unresponsiveness of some residential consumers equity issues and high cost of the metering infrastructure the aim of this paper is to investigate and present some of the challenges in achieving effective voluntary demand reduction based on a review of residential demand response literature as well as the general residential energy use behaviour literature the authors propose the use of a hybrid engineering approach using social psychology and economic behaviour models to overcome these challenges and realize the benefits of supply security and cost management

the effect of unions on the structure of wages a longitudinal analysis this paper studies the effects of unions on the structure of wages using an estimation technique that explicitly accounts for misclassification errors in reported union status and potential correlations between union status and unobserved productivity the econometric model is estimated separately for five skill groups using a large panel data set formed from the u s current population survey the results suggest that unions raise wages more for workers with lower levels of observed skills in addition the patterns of selection bias differ by skill group among workers with lower levels of observed skill unionized workers are positively selected whereas union workers are negatively selected from among those with higher levels of observed skill despite a large and sophisticated literature there is still substantial disagreement over the extent to which differences in the structure of wages between union and nonunion workers represent an effect of trade unions rather than a consequence of the nonrandom selection of unionized workers over the past decade several alternative approaches have been developed to control for unobserved heterogeneity between union and nonunion workers 2 one method that has been successfully applied in other areas of applied microeconometrics is the use of longitudinal data to measure the wage gains or losses of workers who change union status unfortunately longitudinal estimators are highly sensitive to measurement error even a small fraction of misclassified union status changes can lead to significant biases if the true rate of mobility between union and nonunion jobs is low this sensitivity led lewis 1986 to essentially dismiss the longitudinal evidence in his landmark survey of union wage effects in this paper i present some new evidence on the union wage effect based on a longitudinal estimator that explicitly accounts for misclassification errors in reported union status the estimator uses external information on union status misclassification rates along with the reduced form coefficients from a multi variate regression of wages on the observed sequence of union status indicators to isolate the causal effect of unions from any selection biases introduced by a correlation between union status and the permanent component of unobserved wage heterogeneity recognizing that unions may raise wages more or less for

a new index of financial conditions we use factor augmented vector autoregressive models with time varying coefficients and stochastic volatility to construct a financial conditions index that can accurately track expectations about growth in key us macroeconomic variables time variation in the models parameters allows for the weights attached to each financial variable in the index to evolve over time furthermore we develop methods for dynamic model averaging or selection which allow the financial variables entering into the financial conditions index to change over time we discuss why such extensions of the existing literature are important and show them to be so in an empirical application involving a wide range of financial variables

the effects of unions on investment and innovation evidence from wirs the above is representative of much popular discussion of the effects of unions on investment and innovation in the professional literature the view that unions deter investment by expropriating quasi rents is also commonplace see e g simons i944 baldwin i983 grout i984 in addition it is argued that union foisted restrictive work practices might make investment a more costly process see e g denny and nickell i989 in recent years the above theoretical notions have appeared to receive some empirical support in that in the united states the level of the investment capital ratio does appear to be lower in union firms see hirsch i988 and references therein in this paper we use information contained in the i 984 workplace industrial relations survey in order to investigate the actual impact of unions on investment the rest of the paper is organised as follows in section i i we informally review the alternative channels through which unions might affect investment section i 2 contains a simple theoretical model of investment which embodies all the alternative channels our results are to be found in section ii and finally some conclusions are contained in section iii

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

do unions reduce investment evidence from canada the authors test for a link between unionization and net investment rates in canadian manufacturing analysis of data on 18 industries for the years 1967 87 reveals a negative non linear relationship the presence of unions appears to have reduced investment when the percentage of firms in the industry that were unionized was between 0 and approximately 50 with a plateau or slight positive marginal effect above this level in an industry moving from no unions to the mean level of unionization net investment and gross investment are predicted to fall by 66 74 and 18 25 respectively

technical efficiency unions and decentralized labor contracts abstract this paper explores the link between the presence of unions in the workplace the adoption of decentralized labor agreements and technical efficiency using a large sample of italian manufacturing firms we apply the data envelopment analysis and its robust version based on bootstrap theory to get reliable estimates of technical efficiency at the firm level in a standard first stage we devote particular attention to the specific technology adopted by distinguishing 20 different sector frontiers as well as to the presence of outliers the obtained efficiency scores are analyzed in a second stage applying a truncated regression model estimated via maximum likelihood following the simar and wilson 2007 2011 methodology our results highlight that the presence of workplace unionization decreases the level of technical efficiency while aspects limiting the unions power such as a strong exposure to international markets high debt levels or the prevalence of flexible assets partially reduce the negative effect however when firms adopt decentralized labor contracts agreements the effect on efficiency is positive and partially compensates the negative unions effect

the creation and capture of rents wages and innovation in a panel of u k companies this paper examines the impact of technological innovation on wages using a panel of british firms a head count measure of major innovations between 1945 and 1983 is combined with share price and accounting information innovating firms are found to have higher average wages but rival innovation tends to depress own wages this appears consistent with a model where wages are partly determined by a sharing in the rents generated by innovation in other words innovation may be a good instrument for proxies for rents such as profitability quasi rents or tobin s average q instrumental variable estimates of the elasticity between wages and quasi rents are about 0 29

wage compression within the firm evidence from an indexation scheme we revisit the role of labour market institutions by showing how they affect the sharing of firm specific rents between employers and employees we look at an italian wage indexation mechanism scala mobile that compressed the distribution of wages imposing real wage increases at the bottom of the distribution after developing a simplified version of a search model with intra firm bargaining and on the job search we document that skilled workers received lower wage adjustments when employed at firms with many unskilled workers and they tended to move towards more skill intensive firms moreover the system drove the least skill intensive firms out of the market

the demand for residential industrial and total electricity 1973 1998 this paper estimates residential industrial and total electricity demand by a partial adjustment approach and by a simultaneous equation approach simultaneous equation models are more appropriate since they provide negative price elasticity estimates for the residential industrial and total electricity samples flow adjustment models yield positive price elasticity estimates in some cases suggesting they fail to identify proper supply considerations that may be influencing prices the simultaneous equation approach suggests that residential customers are more price sensitive than industrial customers weather seems to have the greatest impact on the residential sector and cold weather appears to affect demand more than hot weather

economic potential of demand response at household level are central european market conditions sufficient abstract the aim of this paper is to show the economic potential of demand response dr on household level at central european market conditions thereby required economic benefits for consumers participation the realistic load shifting potential at household level and the estimation of essential intelligent infrastructure costs are discussed the core of this paper builds a case study applying spot market oriented load shifting from the supplier s point of view by using austrian electricity market data household load profiles as well as a heat pump and e car charging load profile it is demonstrated which cost savings for suppliers can be derived from such load shifting procedure at household level furthermore upper cost limits for intelligent infrastructure in order to break even are derived results suggest to take a critical look at european discussions on dr implementation on household level showing that at central european market conditions the potential for dr at household level is restricted to significant loads and hence the applied load shifting strategy is only beneficial with application to heat pumps in contrast the frequently discussed shifting of conventional household devices loads such as washing machines economically does not add up

efficient pricing and investment in electricity markets with intermittent resources facing growing technological and environmental challenges the electricity industry needs effective pricing mechanism to promote efficient risk management and investment decisions in a restructured electricity market with competitive wholesale prices and traditionally regulated retail rates however there are technical and institutional barriers that prevent dynamic pricing with price responsive demand in regions with limited energy storage capacity intermittent renewable resources present special challenges this could adversely affect the effectiveness of public policies causing inefficient investments in energy technologies in this paper we present an updated economic model of pricing and investment in restructured electricity market and use the model in a simulation study for an initial assessment of renewable energy strategy and alternative pricing mechanisms a key objective of the study is to shed light on the policy issues so that effective decisions can be made to improve efficiency

an integration of trade union models in a sequential bargaining framework this paper aims to embed two popular models of trade union behavior the monopoly model and the efficient bargaining model in a more general framework it does this by analyzing sequential bargaining models where wages are determined before employment and the power of the union in the two stages of the bargain differs as well as finding that the monopoly and efficient bargain models are special cases of this model a new class of models is also discovered this framework is used to analyze the relationship between union pow er and efficiency the empirical analysis of trade unions and the effects of trade union legislation copyright 1987 by royal economic society

system behaviour modelling for demand response provision in a smart grid while pilot projects in the smart grid domain have abounded through public and private efforts there is still uncertainty in identifying effective business models for the smart grid in this paper we take the view of a new entrant in this market acting as a third party provider of demand response new entrants are a key player in emerging technological domains but simulation and policy analysis from this perspective have not been forthcoming we present a novel approach for evaluating business models within a regulatory context and avoid committing to specific technical solutions but instead embark on a parameter exploration through simple yet insightful agent based models our simulations analyse the impact of system performance by three key variables participant population size household flexibility in terms of the maximum number of dr events allowed and size of load shifting shedding available the simulations indicate that benefits of avoided capital investment leads to valuing a participating household at approximately 1800 over a 20 year period these results show how mandated infrastructure influenced by policy can affect the value proposition of a demand response service and provide a useful reference for system level parameter requirements with weak business models policy decisions can be crucial in providing the impetus needed to spur growth in this market

spot and derivative pricing in the eex power market using spot and futures price data from the german eex power market we test the adequacy of various one factor and two factor models for electricity spot prices the models are compared along two different dimensions 1 we assess their ability to explain the major data characteristics and 2 the forecasting accuracy for expected future spot prices is analyzed we find that the regime switching models clearly outperform its competitors in almost all respects the best results are obtained using a two regime model with a gaussian distribution in the spike regime furthermore for short and medium term periods our results underpin the frequently stated hypothesis that electricity futures quotes are consistently greater than the expected future spot a situation which is denoted as contango

rent sharing holdup and wages evidence from matched panel data rent sharing by workers can reduce the incentives for investment if some of the returns to sunk capital are captured in higher wages we propose a simple measure of this holdup effect based on the size of the wage offset for firm specific capital accumulation using social security earnings records for workers in the veneto region of italy linked to detailed financial data for their employers we find strong evidence of rent sharing with an elasticity of wages with respect to potential rents per worker of around 4 arising mainly at larger firms with higher price cost margins on the other hand we find little evidence that bargaining lowers the return on investment instead firm level bargaining appears to split the rents after deducting the full cost of capital

reducing the market impact of large shares of intermittent energy in denmark abstract the increasing prevalence of renewable and intermittent energy sources in the electricity system is creating new challenges for the interaction of the system in denmark high renewable shares have been achieved without great difficulty mainly due to the flexibility of the nearby nordic hydro power dominated system further increases in the share of renewable energy sources require that additional options are considered to facilitate integration with the lowest possible cost with large shares of intermittent energy the impact can be observed on wholesale prices giving both lower prices and higher volatility a lack of wind that causes high prices is rarely seen because long periods without wind are uncommon therefore we focus on the low price effects and the increased value of flexible demand options on the supply side there is an increase in the value of other flexible generation technologies and the attractiveness of additional interconnection capacity this paper also analyses options for increasing the flexibility of heat generation involving large and decentralized chp plants and heat generation based on electricity the incentives that the market provides for shifting demand and using electricity for heat production are discussed based on the variability of prices observed from 2006 to 2008

sunk investment bargaining and choice of capital structure this paper shows how a firm might optimally choose debt to affect the outcome of bilateral bargaining with workers or other input suppliers it is shown that debt may alleviate the well known underinvestment problem associated with the inability to write precommitment contracts also in such circumstances debt could be pareto improving over complete equity financing the relationship between the optimal level of debt and asset specificity of investment and bargaining power of the firm vis a vis the workers is explored the williamson conjecture that higher asset specificity will lead to less debt is shown not to be valid in general

rent sharing and collective wage contracts evidence from german establishment level data using german establishment level data this article analyses whether wages respond to firm specific profitability conditions particular emphasis is given to the question of whether the extent of rent sharing varies with collective bargaining coverage in this context two conflicting hypotheses are tested the first one asserts that unions exploit their bargaining power at the firm level and appropriate a larger share of rents than the bargaining parties in uncovered firms the second one states that unions favour a compressed intra industry wage structure and suppress the responsiveness of wages to firm specific profitability conditions the empirical analysis provides strong support for the second hypothesis while pooled ordinary least squares pols estimates yield positive estimates of the rent sharing coefficient in covered establishments dynamic panel data estimates accounting for unobserved heterogeneity and the endogeneity of rents point to a rent sharing coefficient of zero

do works councils inhibit investment theoretische uberlegungen deuten darauf hin dass firmen durch arbeitnehmervertretungen auf betriebsebene wie gewerkschaften mit einem hold up problem konfrontiert werden da letztere sich einen teil der quasi renten aus langlebigen kapitalinvestitionen aneignen konnen deshalb mogen die firmen ihre anfalligkeit fur derartiges rent seeking dadurch verringern dass sie ihre investitionen zuruckfahren wahrend es fur diese hypothese empirische bestatigungen durch firmenstudien aus den usa gibt untersuchen wir ob dies auch in dem unterschiedlichen institutionellen umfeld in deutschland der fall ist wo statt betriebsgewerkschaften betriebsrate eine ahnliche rolle spielen konnen unter verwendung von parametrischen und nichtparametrischen methoden sowie von betriebspaneldaten finden wir keine empirischen hinweise darauf dass die errichtung bzw abschaffung eines betriebsrates einen negativen bzw positiven einfluss auf das betriebliche investitionsverhalten hat

prediction with misspecified models many decision makers in the public and private sectors routinely consult the implications of formal economic and statistical models in their work especially in large organizations and for important decisions there are often competing models of course no model under consider ation is a literal representation of reality for the purposes at hand more succinctly no model is true and different models focus on different aspects of the relevant environment this fact can often be supported by formal econometric tests concluding that the models at hand are indeed misspecified in various dimensions there are well developed practical bayesian procedures with solid theoretical foundations for combining competing models in decisionmaking geweke 2005 section 1 5 but these procedures all condition on one of the models under consideration being true non bayesian model selection procedures may be less formal but proceed under the same maintained hypothesis this leads to the common situation in which decision makers are left to balance informally the various predictions and decisions that are formal consequences of competing economic and statistical models in this circumstance serious attention is typically granted to the implications of models to which formal econometric procedures assign very little credence the approach taken here draws on a literature long established in statistics and recently emerging in econometrics that dispenses with the condition that one of the models under consider ation is true in its place it substitutes a log scor

wages profits and rent sharing the paper suggests a new test for rent sharing in the u s labor market using an unbalanced panel from the manufacturing sector it shows that a rise in a sector s profitability leads after some years to an increase in the long run level of wages in that sector the paper controls for workers characteristics for industry fixed effects and for unionism lester s range of wages is estimated for rent sharing reasons alone at approximately 24 per cent of the mean wage

rent sharing and wages evidence from company and establishment panels a central question in labor economics and macroeconomics is whether the textbook competitive model provides an adequate representation of the labor market using longitudinal data on companies and establishments this article suggests that it may not as predicted by rent sharing models of the labor market changes in profitability are shown to feed through into long run changes in wages these are not temporary wage effects and are not driven by the unionized workplaces in the data the article s estimates imply that for rent sharing reasons alone lester s range of wages is approximately 16

real wage determination and rent sharing in collective bargaining agreements the microeconomic forces that influence real wages are not fully understood this paper studies pay determination using data on approximately 600 labour contracts it finds that the real wage is an increasing function of past profitability in the employer s industry and a decreasing function of the level of unemployment in the employer s region these results are consistent with rent sharing theories

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

incentives work getting teachers to come to school we use a randomized experiment and a structural model to test whether monitoring and financial incentives can reduce teacher absence and increase learning in india in treatment schools teachers attendance was monitored daily using cameras and their salaries were made a nonlinear function of attendance teacher absenteeism in the treatment group fell by 21 percentage points relative to the control group and the children s test scores increased by 0 17 standard deviations we estimate a structural dynamic labor supply model and find that teachers respond strongly to financial incentives our model is used to compute cost minimizing compensation policies jel i21 j31 j45 o15

rent sharing and collective bargaining coverage evidence from linked employer employee data using a linked employer employee data set this paper analyses the relationship between firm profitability and wages particular emphasis is given to the question of whether the sensitivity of wages to firm specific rents varies with collective bargaining coverage to address this issue we distinguish sector specific wage agreements firm specific wage agreements and wage determination without any bargaining coverage our findings indicate that individual wages are positively related to firm specific rents in the non union sector and under firm specific contracts industry wide wage contracts however seem to suppress firm level rent sharing while pooled ols estimates yield a positive correlation between wages and quasi rents under centralised contracts estimates accounting for unobserved individual and establishment heterogeneity point to a coefficient of zero differenced gmm estimates accounting for the endogeneity of our profitability measure even point to a negative relationship under centralised contracts

consumption network effects in this paper we study the relevance and mechanics of consumption network effects we use long panel data on the entire danish population to construct a measure of consumption based on administrative tax records and define the peer groups in terms of workplace occupation education and age we then apply an iv strategy and fixed effect models to recover the effects our instruments arise naturally from the network structure and firms shocks the estimated effects are statistically significant and relevant for policies as they generate non negligible multiplier effects further the results are consistent with a keeping up model

union rent seeking intangible capital and market value of the firm abstract this study considers the effect of unions on intangi ble capital investment and profitability within the context of a market value rather than a more traditional accounting based approach theory is provided suggesting unions are able to affect profitability by sharing in the economic returns to firm specific intangible capital in support of this hypothesis we find unionization reduces the returns to r d and produces a corresponding limiting influence on r d investment at the firm level i introduction a n extensive literature in economics has ex amined the determinants of profitability with much of the focus centering on the role of market structure only recently however have the effects of labor unions on profitability been analyzed ths is surprising since labor economists long have emphasized union influences on wages and productivity that in turn may affect profitabil ity in recent studies freeman 1983 and karier 1985 report a significant limiting influence of unions on price cost margins in high concentra tion manufacturing industries using firm level data and the market based tobin s

insurance within the firm we evaluate the allocation of risk between firms and their workers using matched employer employee panel data unlike previous contributions this paper focuses on idiosyncratic shocks to the firm which are the correct empirical counterpart of the theoretical notion of diversifiable risk we allow for both temporary and permanent shocks to output and find that firms absorb temporary fluctuations fully but insure workers against permanent shocks only partially risk sharing considerations can account for about 15 percent of overall earnings variability the remainder originating from idiosyncratic shocks to individual workers our welfare calculations indicate that firms are an important vehicle of insurance provision

shifting load through space the economics of spatial demand side management using distributed data centers demand side flexibility dsf in the electricity grid has become an active research area in recent years while temporal flexibility e g load shedding load shifting is already discussed intensively in literature spatial load migration still is an under researched type of dsf spatial load migration allows us to instantly migrate power consuming activities among different locations data centers dcs are power intensive and process information goods since information goods are easily transferable through communication networks power intensive processing of information goods is not necessarily tied to a specific location consequently geographically distributed dcs inherit in theory a considerable potential to globally migrate load we analyze the economics of spatially migrating load to provide balancing power using geographically distributed dcs we assure that neither of the participating electricity grids will be burdened by this mechanism by using historical data to evaluate our model we find reasonable economic incentives to migrate positive as well as negative balancing power in addition we find that current scenarios favor the migration of negative balancing power our research thus reveals realistic opportunities to virtually transfer balancing power between different market areas worldwide

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

bargaining power fear of disagreement and wage settlements theory and evidence from u s industry the paper develops and estimates a theoretical model of wage determination and union nonunion wage differentials in order to overcome the institutional ctiticisms of the formal bargaining literature the paper generalizes the nash zeuthen harsanyi model by linking the solution to the institutional concepts of bargaining power and fear or cost of disagreement and by making the outcome depend not only on endogenous but also on exogenous factors an operational specification of bargaining power and fear of disagreement allows the model to be estimated with data covering twelve companies and trade unions during the period from mid 1950 s to the late 1970 s while giving limited support to the nashzeuthen harsanyi solution the empirical analysis indicates that the bargaining outcome usually deviates from the nash zeuthen harsanyi point and in accordance with the institutionalist claim that it varies significantly with exogenous factors contrary to the traditional labor economics view the results do not support the general conclusion that the bargaining solution lies on the marginal revenue product curve of labor instead the relevant coefficients suggest that for many firms and unions the outcome might be better characterized by the efficient contract vertical contract curve

sunk capital unions and the hold up problem theory and evidence from cross country sectoral data abstract in this paper we study the hold up problem by considering the effect of union bargaining power on the level of investment per worker across sectors characterised by different levels of sunk capital investment we develop a search and matching model with heterogeneous sectors and ex post collective wage bargaining and test the predictions of the model using a difference in difference approach on manufacturing sector data in a set of oecd countries during the period 1980 2000 we find that union power reduces investment per worker particularly in sunk capital intensive industries we refine our empirical analysis showing that the underlying hold up problem is exacerbated when strikes are not regulated after a collective contract is signed and there is no arbitration while the presence of social pacts may sustain cooperative equilibria that alleviate the hold up problem our results are robust to a series of controls and possible endogeneity of union power

on the use of holdout samples for model selection researchers often hold out data from the estimation of econometric models to use for external validation however the use of holdout samples is suboptimal from a bayesian perspective which prescribes using the entire sample to form posterior model weights this paper examines a possible rationale for the use of holdout samples data inspired modifications of structural models are likely to lead to an exaggeration of model fit the use of holdout samples can in principle set an incentive for the modeler not to exaggerate model fit

underlying trends and seasonality in uk energy demand a sectoral analysis this paper demonstrates the importance for energy demand modelling of allowing for trends and seasonal effects that are stochastic in form inherent underlying trends may be non linear and reflect not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction using quarterly unadjusted data for various sectors in the uk it is shown that unless energy demand models are formulated so as to allow for stochastic trends and seasonals estimates of price and income elasticities could be seriously biased

a review on implementation strategies for demand side management dsm in kuwait through incentive based demand response programs abstract since the export of fossil fuel is the backbone of kuwait s economy the enormous upsurge in the internal fuel consumption creates anguish and bane at present 46 of the internal fossil fuel consumption is used for electricity generation the increase in fuel consumption hurled kuwait as one of the highest per capita electricity consuming as well as co 2 emitting countries in the world consumers pay only 6 of the production cost of electricity the government subsidizes the balance which is one of the major reasons behind the high electricity consumption in the country any reduction in electricity consumption can positively reflect on both per capita electricity consumption and co 2 emission additionally the saved fossil fuel can be exported to generate revenue to support the country s economy worldwide demand side management dsm is considered as an effective tool to curtail electricity demand the objective of this review paper is to explore the available literature to find out the most suitable dsm measures to control the growth of per capita electricity consumption in kuwait after conducting a detailed strengths weaknesses opportunities and threats swot analysis it is concluded that incentive based demand response programs can be considered as one of the most suitable solutions to address this problem

labour markets and innovation ex post bargaining abstract there is considerable interest in how labour market conditions affect innovation lying behind much of the existing work on this question is a simple model of a single union bargaining with a single firm in which in the absence of binding contracts the union reduces the returns to innovation without bearing any of the costs this misses an important feature of some rd with efficient contracts there are cases where being faced with a stronger union will help a firm to win a patent race it would otherwise have lost

unionization incomplete contracting and capital investment this article examines empirically the hypothesis that incomplete contracts and resulting opportunistic behavior over the return to sunk assets reduces investment union firm contracts are incomplete because they 1 do not prevent all actions aimed at changing the existing contract 2 cover a relatively short time period and 3 do not extend to union members yet to be hired the primary response of firms is to reduce investment in specific durable assets and also to reduce employment growth and increase debt the authors find fairly strong evidence of these effects in a sample of large publicly traded firms using firm specific measures of unionization copyright 1993 by university of chicago press

who profits from patents rent sharing at innovative firms this article analyzes how patent induced shocks to labor productivity propagate into worker compensation using a new linkage of u s patent applications to u s business and worker tax records we infer the causal effects of patent allowances by comparing firms whose patent applications were initially allowed to those whose patent applications were initially rejected to identify patents that are ex ante valuable we extrapolate the excess stock return estimates of kogan et al 2017 to the full set of accepted and rejected patent applications based on predetermined firm and patent application characteristics an initial allowance of an ex ante valuable patent generates substantial increases in firm productivity and worker compensation by contrast initial allowances of lower ex ante value patents yield no detectable effects on firm outcomes patent allowances lead firms to increase employment but entry wages and workforce composition are insensitive to patent decisions on average workers capture roughly 30 cents of every dollar of patent induced surplus in higher earnings this share is roughly twice as high among workers present since the year of application these earnings effects are concentrated among men and workers in the top half of the earnings distribution and are paired with corresponding improvements in worker retention among these groups we interpret these earnings responses as reflecting the capture of economic rents by senior workers who are most costly for innovative firms to replace

does consumer demand reproduce inequality high income consumers vertical differentiation and the wage structure1 this article considers the effects on the wage structure of the u s economy s growing reliance on demand from high income consumers relative to the mass consumers that defined the post world war ii u s economy high income consumers are willing to pay for high quality and high status products these spending patterns split producers into up market and down market segments and stoke winner take all dynamics among up market producers economic dependence on high income consumers could thus lead to a new form of industrial segmentation based on vertical differentiation by product quality or status to test these predictions data from consumer expenditure and wage surveys are linked using input output tables and used to fit variance function regressions results show that industries more dependent on high income consumers have greater wage inequality this analysis identifies a new structural source of wage inequality not considered in previous research the increasingly unequal composition of consumer d

residential electricity pricing in china the context of price based demand response abstract as a secondary energy electricity is an important channel between original energy and energy consumers electricity price is a critical factor for the interests of all involvers in the electric power market it also plays an important role for the sustainable development of energy and environment smart grid is a new conception proposed in recent years to improve the intelligent level and increase the efficiency of electric power system operation smart grid combines and integrates information technology communication technology and intelligent control technology with tradition power system to achieve the many objectives of smart grid demand response dr as an effective technique of demand side management dsm refers to the changes in electricity consumption behavior of users in response to the dynamic price or incentive rewards price based demand response pbdr is one of the two major dr programs in this paper we first introduce the pricing theories in economics the pricing of electricity and the development of electricity pricing in china then we present a detailed discussion on the pbdr strategies in the dsm of smart grid also the research status of pbdr is reviewed finally it gives a summary of the whole paper in the last section

union effects on productivity profits and growth has the long run arrived this article interprets literature examining union effects on economic performance production function studies indicate small overall union impacts on productivity positive effects where they exist appear to result from management response to decreased profit expectations and from a natural selection process lower profitability among unionized firms is well established more interesting is the possibility that unions appropriate quasi rents deriving from long lived tangible and intangible capital the connection between unions investment behavior and productivity growth emerges as a particularly fruitful line of empirical inquiry although it does not encourage a sanguine view of unionism s long run impact

bargaining sorting and the gender wage gap quantifying the impact of firms on the relative pay of women there is growing evidence that rm specic pay premiums are an important source of wage inequality these premiums will contribute to the gender wage gap if women are less likely to work at high paying rms or if women negotiate worse wage bargains with their employers than men using longitudinal data on the hourly wages of portuguese workers matched with balance sheet information for rms we show that the wages of both men and women contain rm specic premiums that are strongly correlated with employer productivity we then show how the impact of these rm specic pay dierentials on the gender wage gap can be decomposed into a combination of bargaining and sorting eects consistent with the bargaining literature we nd that women receive only 90 of the rm specic pay premiums earned by men notably we obtain very similar estimates of the relative bargaining power ratio from our analysis of between rm wage premiums and from analyzing changes in

rent sharing before and after the wage bill many biases plague the analysis of whether employers share rents with their employees unlike what is predicted by the competitive labour market model using a portuguese matched employer employee panel this article is one of the first to address these biases in three complementary ways 1 controlling directly for the fact that firms that share more rents will ceteris paribus have lower net of wages profits 2 instrumenting profits via interactions between the exchange rate and the share of exports in firm s total sales 3 considering firm or firm worker spell fixed effects and highlighting the role of downward wage rigidity these approaches clarify conflicting findings in the literature and result in our preferred specifications in significant evidence of rent sharing a lester range of pay dispersion of 56 also shown to be robust to a number of competitive interpretations

integration scenarios of demand response into electricity markets load shifting financial savings and policy implications abstract demand response allows for the management of demand side resources in real time i e shifting electricity demand according to fluctuating supply when integrated into electricity markets demand response can be used for load shifting and as a replacement for both control reserve and balancing energy these three usage scenarios are compared based on historic german data from 2011 to determine that load shifting provides the highest benefit its annual financial savings accumulate to 3 110 m for both households and the service sector this equals to relative savings of 2 83 compared to a scenario without load shifting to improve demand response integration the proposed model suggests policy implications reducing bid sizes delivery periods and the time lag between market transactions and delivery dates in electricity markets
