investigating preferences for dynamic electricity tariffs the effect of environmental and system benefit disclosure dynamic electricity pricing can produce efficiency gains in the electricity sector and help achieve energy policy goals such as increasing electric system reliability and supporting renewable energy deployment retail electric companies can offer dynamic pricing to residential electricity customers via smart meter enabled tariffs that proxy the cost to procure electricity on the wholesale market current investments in the smart metering necessary to implement dynamic tariffs show policy makers resolve for enabling responsive demand and realizing its benefits however despite these benefits and the potential bill savings these tariffs can offer adoption among residential customers remains at low levels using a choice experiment approach this paper seeks to determine whether disclosing the environmental and system benefits of dynamic tariffs to residential customers can increase adoption although sampling and design issues preclude wide generalization we found that our environmentally conscious respondents reduced their required discount to switch to dynamic tariffs around 10 in response to higher awareness of environmental and system benefits the perception that shifting usage is easy to do also had a significant impact indicating the potential importance of enabling technology perhaps the targeted communication strategy employed by this study is one way to increase adoption and achieve policy goals

cooperative and noncooperative r d in duopoly with spillovers contrary to the usual assumption made in most oligopoly models relations among firms are seldom of a wholly cooperative or noncooperative type in many situations they compete in some fields while they cooperate in others an important example is the case of cooperative research efforts bringing fierce competitors together two types of agreement are observed first r d cooperation can take place at the so called precompetitive stage companies share basic information and efforts in the r d stage but remain rivals in the market place 1 a second type of agreement involves an extended collusion between partners creating common policies at the product level the usual justifications of this extension are the difficulties of protecting intellectual property the idea is then to allow partners who have achieved inventions together to also control together the processes and products which embody the results of their collaboration in order to recuperate jointly their r d investments 2 what could be expected from these types of agreement is a reduction in r d expenditures because of less wasteful duplication and a reduction of total production because of more reprinted from the american economic review 78 5 1133 1137 1988 center for operations research econometrics 1348 louvain la neuve belgium we are grateful to jean

comparison of forecast performance for homogeneous heterogeneous and shrinkage estimators some empirical evidence from us electricity and natural gas consumption abstract maddala et al journal of business and economic statistics 15 1997 90 obtained short run and long run elasticities of energy demand for each of 49 us states over the period 1970 1990 they showed that heterogeneous time series estimates for each state yield inaccurate signs for the coefficients while panel data estimates are not valid because the hypothesis of homogeneity of the coefficients was rejected their preferred estimates are those obtained using the shrinkage estimator this paper contrasts the out of sample forecast performance of heterogeneous panel and shrinkage estimators using the maddala et al journal of business and economic statistics 15 1997 90 electricity and natural gas data sets our results show that the homogeneous panel data estimates give the best out of sample forecasts

from frugal jane to wasteful john a quantile regression analysis of swiss households electricity demand abstract in this article we investigate the heterogeneity in the responsiveness of swiss household electricity demand to changes in prices and income we focus on segments of consumers with different intensities of electricity consumption by using a panel quantile regression approach this estimation strategy is applied to a rich micro level longitudinal data set of 3880 observations from more than 1400 households matched with a unique price data set extracted from the swiss electricity regulator s online sources while the findings show an inelastic electricity demand across all groups an interesting pattern of variation emerges between lower and upper quantiles of electricity demand respectively frugal and intensive users results show that households in the first conditional quartile and at the median react significantly to changes in prices while those at the lowest quantile and upper quantiles exhibit insignificant price elasticities the main policy implications of this work concern the design of price based measures for reducing electricity consumption in the residential sector and the possibility of accounting for individual responses in tailoring policies for specific consumer segments

antitrust for high technology industries assessing research joint ventures and mergers the purpose of this paper is to analyze if and how the standard methodology of antitrust analysis should be modified to reflect the importance of r and d and innovation as competitive forces and engines of economic progress focus is on such r and d intensive business combinations as research joint ventures rjvs and horizontal mergers in high technology industries the authors do not propose a complete set of guidelines for the assessment of such combinations they present an economic model of rjvs and high technology mergers that might serve as an analytical underpinning for such guidelines one conclusion of the analysis is that rjvs ought to be accorded special treatment under the antitrust laws this special treatment should entail an explicit recognition that rjvs will be scrutinized under the rule of reason according to guidelines specific to this purpose

dynamic demand for residential electricity in taiwan under seasonality and increasing block pricing abstract this paper studies the dynamic demand for residential electricity in taiwan employing a monthly panel data set composed of 19 counties and spanning the period from 2007 01 to 2013 12 the partial adjustment model used addresses the endogeneity of the electricity price that results from the increasing block pricing the estimated results show that there is a significant seasonal difference in the demand for electricity between the summer and non summer periods both the adjustment speed and own price elasticity during the summer months are found to be lower than those in the non summer months due to the hot weather in summer it is easier for consumers to adjust their electricity consumption in response to the changes in electricity pricing during the non summer time the estimated inelastic short run and long run income effects show that electricity is a necessity for consumers moreover the controversial electricity conservation policies are found to be ineffective measures for reducing electricity consumption in taiwan

a dynamic auction for multi object procurement under a hard budget constraint this contribution revisits the problem of allocating r d subsidies by government agencies typically the applicants financial constraints are private information the literature has recommended the use of auctions in order to reduce information rents and thus improve the efficiency of how scarce public funds are allocated we propose a new open clock auction for this procurement problem this auction is strategically simple as it exhibits truthtelling in dominant strategies and satisfies ex post rationality while observing the budget constraint we test the auction in monte carlo simulation and discuss its applicability and limitations moreover we highlight connections to recent advances in computer science

the effects of public r d subsidies on firms innovation activities the case of eastern germany this study analyzes the effects of public r d policy schemes on the innovation activities of firms in eastern germany the main question in this context is whether public funds stimulate r d activities or simply crowd out privately financed r d empirically we investigate the average causal effects of all public r d schemes in eastern germany using a nonparametric matching approach compared to the case in which no public financial means are provided it turns out that firms increase their innovation activities by about four percentage points

targeting the poor evidence from a field experiment in indonesia the brief summarizes the targeting the poor evidence from a field experiment in indonesia for the period december 2008 january 2009 this paper reports an experiment in 640 indonesian villages on three approaches to target the poor proxy means tests pmt where assets are used to predict consumption community targeting where villagers rank everyone from richest to poorest and a hybrid defining poverty based on ppp 2 per capita consumption community targeting and the hybrid perform somewhat worse in identifying the poor than pmt though not by enough to significantly affect poverty outcomes for a typical program elite capture does not explain these results instead communities appear to apply a different concept of poverty

the impact of unconditional cash transfer on fuel choices among ultra poor in pakistan quasi experimental evidence from the benazir income support program abstract we analyze the impact of the unconditional cash transfer program namely the benazir income support program bisp on fuel choices among ultra poor in pakistan using two rounds of household level data collected in 2011 and 2016 the analysis based on regression discontinuity design shows that bisp cash transfer has a significant impact on interfuel substitution cash transfer increases the use of modern fuels among bisp beneficiaries besides cash transfer also encourages the use of intermediate fuels even in some cases traditional fuels cash transfer also increases the share of fuel expenses in total household expenses therefore the fuel stacking theory provides a better explanation of interfuel substitution than the energy ladder theory of the cash transfer program the provincial analysis shows that interfuel substitution exists due to cash transfer but varies from province to province signifying the role of regional heterogeneities the net impact on fuel choices may depend on the availability of different fuel components from policy perspective the expansion of the cash transfer program as planned by the government would require a reasonable investment in the energy sector to ensure an uninterrupted supply of modern fuels

is public r d a complement or substitute for private r d a review of the econometric evidence is public r d spending complementary and thus additional to private r d spending or does it substitute for and tend to crowd out private r d conflicting answers are given to this question we survey the body of available econometric evidence accumulated over the past 35 years a framework for analysis of the problem is developed to help organize and summarize the findings of econometric studies based on time series and cross section data from various levels of aggregation laboratory firm industry country the findings overall are ambivalent and the existing literature as a whole is subject to the criticism that the nature of the experiment s that the investigators envisage is not adequately specified we conclude by offering suggestions for improving future empirical research on this issue

cooperative and noncooperative r d in an oligopoly with spillovers this paper examines the positive and normative effects of cooperative r d whereby member firms commit themselves to the joint profit maximizing level of r d in a precompetitive stage but remain fierce competitors in the product market vis a vis noncooperative r d socially first best r d and socially second best r d in the presence of sufficiently large r d spillovers neither noncooperative nor cooperative equilibria achieve even second best r d levels in the absence of spillover effects however while the cooperative r d level remains socially insufficient the noncooperative level may overshoot first and second best levels of r d copyright 1992 by american economic association

response of residential electricity demand to price the effect of measurement error abstract in this paper we present an empirical analysis of the residential demand for electricity using annual aggregate data at the state level for 48 us states from 1995 to 2007 earlier literature has examined residential energy consumption at the state level using annual or monthly data focusing on the variation in price elasticities of demand across states or regions but has failed to recognize or address two major issues the first is that when fitting dynamic panel models the lagged consumption term in the right hand side of the demand equation is endogenous this has resulted in potentially inconsistent estimates of the long run price elasticity of demand the second is that energy price is likely mismeasured to address these issues we estimate a dynamic partial adjustment model using the kiviet corrected least square dummy variables lsdv 1995 and the blundell bond 1998 estimators we find that the long term elasticities produced by the blundell bond system gmm methods are largest and that from the bias corrected lsdv are greater than that from the conventional lsdv from an energy policy point of view the results obtained using the blundell bond estimator where we instrument for price imply that a carbon tax or other price based policy may be effective in discouraging residential electricity consumption and hence curbing greenhouse gas emissions in an electricity system mainly based on coal and gas power plants

real time pricing of electricity for residential customers econometric analysis of an experiment under real time pricing a network operator sets the price level for a period according to a predefined scheme which depends on the state of demand and costs and announces this price shortly before the period begins the french state owned electric utility experimented with a six rate real time tariff which divides the year into three types of days and each day into two periods the number of days of each type is known in advance to the consumer but the type of any particular day is announced only at the end of the preceding day in order to evaluate the responsiveness of customers to this pricing option we estimate the frisch demand functions for daily electricity consumption derived from a simple dynamic model based on an additively separable intertemporal utility function as the marginal utility of expenditure which enters the frisch demands follows a known stochastic process the econometric model has a state space representation we can then apply the kalman filter to compute the log likelihood function associated with each consumer s time series of electricity consumption the main result of the analysis is that the real time tariff improves the welfare of a majority of consumers participating in the experiment

an analysis of cooperative research and development i analyze the effects of cooperative research whereby member firms agree to share the costs andfruits of a research project before they undertake it in this model industrywide agreements tend to have socially beneficial effects when the degree ofproduct market competition is low when there are r d spillovers in the absence of cooperation when a high degree of sharing is technologically feasible and when the agreement concerns basic research rather than development activities i show that a royalty free cross licensing agreement among any number offirms lowers the equilibrium level of innovation even though it increases the efficiency of r d through sharing

residential electricity demand in spain new empirical evidence using aggregate data this paper presents an empirical analysis on residential demand for electricity this analysis has been performed using aggregate panel data at the province level for 47 spanish provinces for the period from 2000 to 2008 for this purpose we estimated a log log demand equation for electricity consumption using a dynamic partial adjustment approach this dynamic demand function has been estimated using a two step system gmm estimator proposed by blundell and bond 1998 the purpose of this empirical analysis is to highlight some of the characteristics of spanish residential electricity demand particular attention has been paid to the influence of price income and weather conditions on electricity demand the estimated short and long run own price elasticities are negative as expected but lower than 1 furthermore weather variables have a significant impact on electricity demand

value of price responsive load for wind integration in unit commitment the ability of load to respond to short term variations in electricity prices plays an increasingly important role in balancing short term supply and demand especially during peak periods and in dealing with fluctuations in renewable energy supplies however price responsive load has not been included in standard models for defining the optimal scheduling of generation units in short term here elasticities are included to adjust the demand profile in response to price changes including cross price elasticities that account for load shifts among hours the resulting peak reductions and valley fill alter the optimal unit commitment enhancing demand response also increases the amount of wind power that can be economically injected further wind power uncertainty can be managed at a lower cost by adjusting electricity consumption in case of wind forecast errors which is another way in which demand response facilitates the integration of intermittent renewables

earnings and employment effects of continuous off the job training in east germany after unification the effects of continuous off the job training oft for east germans after unification are analyzed in terms of their earnings and employment probabilities using the potential outcome approach to causality as general framework different matching procedures are suggested for the estimation they allow for permanent and transitory shocks that influence oft participation and labor market outcomes the matching procedures also take account of individually different starting dates the data are taken from the german socio economic panel gsoep 1990 1994 this dataset is very informative with respect to factors influencing the participation in training the results show no positive effects of training

choosing organizational modes of strategic technology partnering international and sectoral differences this paper focuses on international strategic technology partnerships and the choice that companies have in terms of the organizational mode either through complex inter organizational modes involving equity sharing or contractual non equity alliances the empirical results show that the choice of particular mode of cooperation varies with the technological characteristics of sectors of industry joint ventures are disproportionately represented in relatively mature industries contractual alliances dominate strategic technology partnering in so called high tech industries

inter firm cooperation with imperfectly appropriable research abstract inter firm collaboration in pre competitive research is not always beneficial rather its effectiveness in raising social benefits relative to a non cooperative setup depends on both the nature of the agreement and the technological and market conditions of the industry in question joint ventures that simply allow members to coordinate their actions in pre competitive research can restore firm incentives for both pre competitive research and development in the presence of high knowledge spillovers and poor opportunities for innovation joint ventures which additionally improve the dissemination of information among member firms raise social benefits whenever the opportunities for innovation are not exceptionally good even in the presence of relatively insignificant spillovers

the impact of classes of innovators on technology financial fragility and economic growth in this article we study innovation processes and technological change in an agent based model by including a behavioral switching among heterogeneous innovative firms the model is able to replicate via simulations well known industrial dynamic and growth type stylized facts the main original element of the model is that firms are allowed to endogenously change among three different classes namely single innovators collaborative innovators and imitators moreover our analysis focuses on the impact of these three innovation categories on micro meso and macro aggregates we find that collaborative companies are those having the highest positive impact on the economic system furthermore we have paid particular attention to the role of credit market in promoting smart growth for this purpose we analyze the role of banks as sources of external funds for innovative entrepreneurs our results suggest a trade off between short term profit maximization and long term efficiency which prevents banks to foster investment in r d and technological progress the model is then used to study the effect that different innovation policies have on macroeconomic performance

the relationship between r d collaboration subsidies and r d performance empirical evidence from finland and germany this study focuses on the impact of innovation policies and r d collaboration in germany and finland we consider collaboration and subsidies as heterogeneous treatments and perform an econometric matching to analyze r d and patent activity at the firm level in general we find that collaboration has positive effects in germany subsidies for individual research do neither exhibit a significant impact on r d nor on patenting but the innovative performance could be improved by additional incentives for collaboration for finnish companies public funding is an important source of finance for r d without subsidies recipients would show less r d and patenting activity whilst those firms not receiving subsidies would perform significantly better if they were publicly funded copyright 2007 john wiley sons ltd

the impact of the bolsa escola familia conditional cash transfer program on enrollment dropout rates and grade promotion in brazil this paper examines the impact of brazil s bolsa escola later renamed bolsa familia program on children s progress in school in brazil the bolsa program which started in the 1990s and expanded rapidly in 2001 and 2002 provides monthly cash payments to poor households if their children between the ages of 6 and 15 are enrolled in school using eight years of school census data from 1998 to 2005 our estimation method compares changes in enrollment and in dropout and grade advancement rates across schools that adopted the bolsa program at different times we estimate that after accounting for cumulative effects the bolsa program has increased enrollment in brazil by about 5 5 percent in grades 1 4 and by about 6 5 percent in grades 5 8 we also estimate that the program has lowered dropout rates by about 0 5 percentage points and raised grade promotion rates by about 0 9 percentage points for children in grades 1 4 and has reduced dropout rates by about 0 4 percentage points and increased grade promotion rates by about 0 3 percentage points for children in grades 5 8 only about one third of brazil s children participate in the bolsa program so the assumption that these results are due only to the impact of the program on participants with no spillover effects onto non participants implies that the impact of participating in the bolsa program is about three times higher than these estimates while these impacts cast a favorable light on the program simple calculations based on the enrollment impacts suggest that the likely benefits in terms of increased wages may not exceed the costs of the program

the real time price elasticity of electricity the real time price elasticity of electricity contains important information on the demand response of consumers to the volatility of peak prices despite the importance empirical estimates of the real time elasticity are hardly available this paper provides a quantification of the real time relationship between total peak demand and spot market prices we find a low value for the real time price elasticity which may partly be explained from the fact that not all users observe the spot market price if we correct for this phenomenon we find the elasticity to be fairly low for consumers currently active in the spot market if this conclusion applies to all users this would imply a limited scope for government intervention in supply security issues

estimation of elasticities for electricity demand in brazilian households and policy implications abstract this paper aims to identify the demand elasticity in energy consumption by brazilian families by using an original household level sample we are the first to identify the average price and income elasticities for brazil we also investigate heterogeneous effects across different quantiles through a quantile regression qr analysis finally we extend the results of the qr analysis and combine them with aggregated data to assess the effects of two price policies a cross subsidy and the recently adopted tariff flags the primary data comes from the household budget survey pof for two periods 1998 99 and 2008 13 conducted in the metropolitan area of sao paulo the price and income elasticities range from 0 46 to 0 56 and from 0 20 to 0 32 respectively the qr results indicate that households behavioral response to a price increase is non uniform across groups and that the reaction is stronger for the lower quantiles additionally tariff flags lead to a more significant reduction in consumption for the low income residences therefore representing a regressive policy on the other hand a cross subsidy that increases the energy price to ordinary residences by 1 could mean a decrease in electricity prices of between 7 5 and 12 4 to low income families

response of residential electricity demand to price in this paper we present an empirical analysis of the residential demand for electricity using annual aggregate data at the state level for 48 us states from 1995 to 2007 we estimate a dynamic partial adjustment model using the kiviet corrected lsdv 1995 and the blundell bond 1998 estimators in addition to the lagged dependent variable our equation includes energy prices income cooling and heating degree days and average household size we find that the short run own price elasticity of consumption is similar across ldsv bias corrected lsdv and the variant of the blundell bond where we instrument for price the short run elasticity is the lowest when we use the blundell bond gmm approach that treats the price of electricity as exogenous the long term elasticities produced by the blundell bond system gmm methods are largest and that from the bias corrected ldsv is greater than that from the conventional lsdv from an energy policy point of view the results obtained using the blundell bond estimator where we instrument for price imply that there is room in an electricity system mainly based on coal and gas power plants for discouraging residential electricity consumption and curbing greenhouse gas emissions by imposing a carbon tax

residential energy demand in the united states analysis using static and dynamic approaches abstract the residential sector is the main consumer of energy in the united states and reducing energy consumption is an important goal for policymakers in each state to know how reducing residential energy demand could be achieved this study develops a set of static and dynamic models to investigate and identify the impact of socio economic and demographic characteristics building age energy prices and weather conditions on residential energy demand at the state level from 2005 to 2013 next this study proposes two alternative scenarios to reduce residential energy demand based on the most precise model for every 10 000 dollars of per capita income in each state 1 increasing residential electricity price by 1 cent per kw h and 2 decreasing average building age by 1 in the first scenario the findings indicate that annual residential electricity demand would decrease by 7 3 on average with the highest reductions in washington 11 9 north dakota 10 9 and idaho 9 7 in the second scenario residential gas demand would decrease by an average of 15 8 annually with the highest reduction in connecticut 33 2 followed by new york 33 0 and massachusetts 30 7 these proposed scenarios assist policymakers in optimizing decisions and investments to reduce residential energy consumption

interactions in swiss households energy demand a holistic approach abstract this article analyzes the interactions and possible trade offs between direct energy consumption and embodied energy requirement of households in switzerland in order to assess the net impacts of standard energy policies focusing exclusively on direct energy use direct and embodied energy demand of swiss households are estimated by combining consumption data of a national expenditure survey with data on energy intensity from life cycle analysis using a system of equations and an instrumental variable approach we find that both domains are driven by same determinants but that there is no evidence for significant substitution between them we also find an increasing effect of income on both domains with particularly important effects on embodied energy from a policy perspective our findings highlight a concern that economic growth could bring about an increasing global energy demand through energy requirement for non energy commodities however the wide spread policies targeting direct energy are unlikely to cause a substantial shift in household consumption to embodied energy

demand customer base line and demand response in the electricity market a survey the increasing use of demand side management as a tool to reliably meet electricity demands at peak time has stimulated interest among researchers consumers and producer organiza tions managers regulators and policymakers this research reviews the growing literature on models which are used to study demand customer base line cbl and demand response in the electricity market after characterizing the general demand models the cbl based on which the demand response models are studied is reviewed given the experience gained from the review and existing conditions the study combines an appropriate model for each case for a possible application to the electricity market moreover it discusses the implications of the results in the literature these aspects are studied independently the main contribution of this survey is attributed to the treatment of the three issues as sequentially interdependent the review is expected to enhance the understanding of the demand cbl and demand response in the electricity market and their relationships the objective is conducted through a combination of demand and supply side managements in order to reduce demand through different demand response programs during peak times this enables electricity suppliers to save costly electricity generation and at the same time reduce energy vulnerability

the diversity of r d consortia and firm behavior evidence from japanese data an empirical analysis of japanese government sponsored r d consortia involving 213 firms over 13 years shows that the diversity of a consortium is associated with greater r d expenditure by participating firms diversity is alternatively measured by the montgomery 1982 index based on 3 digit sic codes and branstetter and sakakibara s 1998 modification of the jaffe 1986 patent portfolio based index

short and long run time of use price elasticities in swiss residential electricity demand abstract this paper presents an empirical analysis on the residential demand for electricity by time of day this analysis has been performed using aggregate data at the city level for 22 swiss cities for the period 2000 2006 for this purpose we estimated two log log demand equations for peak and off peak electricity consumption using static and dynamic partial adjustment approaches these demand functions were estimated using several econometric approaches for panel data for example lsdv and re for static models and lsdv and corrected lsdv estimators for dynamic models the attempt of this empirical analysis has been to highlight some of the characteristics of the swiss residential electricity demand the estimated short run own price elasticities are lower than 1 whereas in the long run these values are higher than 1 the estimated short run and long run cross price elasticities are positive this result shows that peak and off peak electricity are substitutes in this context time differentiated prices should provide an economic incentive to customers so that they can modify consumption patterns by reducing peak demand and shifting electricity consumption from peak to off peak periods

incentive payments in time of day electricity pricing experiments the arizona experience time of day tod demonstration projects have produced some of the most relevant evidence on the cost and benefit of tod in the residential sector the authors clarify an earlier analysis of arizona s incentive scheme and find that homeowners treated the payments differently from regular income but did not make significant shifts in total consumption as a result of tod 11 references 6 tables dck

short and long run elasticities of electricity demand in the korean service sector abstract this paper attempts to examine the electricity demand function in the korean service sector using the annual data covering the period 1970 2011 the short and long run elasticities of electricity demand with respect to price and income are empirically estimated using a co integration and error correction model the short and long run price elasticities are estimated to be 0 421 and 1 002 respectively the short and long run income elasticities are computed to be 0 855 and 1 090 respectively electricity demand in the service sector is inelastic to changes in both price and income in the short run but elastic in the long run therefore it appears that a pricing policy is more effective than the direct regulation of reducing electricity demand in the long run in order to stabilize the electricity demand in the service sector moreover it is necessary to encourage a more efficient use of electricity to cope with increasing demand for electricity following economic growth because the electricity demand in the service sector is income elastic in the long run

endogenous spillovers and the performance of research joint ventures we present a model of r d with endogenous spillovers and demonstrate that noncooperation can produce maximal spillovers the only other noncooperative outcome is minimal spillovers when noncooperation achieves maximal spillovers so does an rjv whereas minimal noncooperative spillovers imply partial but not necessarily maximal spillovers by an rjv partial rjv spillovers are chosen for anti competitive reasons and an rjv may also close a lab for anti competitive reasons the possibility of anti competitive outcomes is precluded in the existing literature on rjvs which focuses on symmetric outcomes our model predicts when anti competitive behaviour by an rjv arises

cooperative r d and vertical product differentiation abstract a partial equilibrium model with vertical product differentiation coumot competition and quality determined by r d expenses is analysed cooperative agreements on r d entail higher levels of r d quality output and welfare than at the non cooperative equilibrium under well denned conditions on spillover rates this confirms in a new setting a well known outcome of models with cost reducing r d further cooperation in r d allows a larger number of firms to operate in the industry than in the non cooperative case via a reduction in prices a new source of social gains from cooperative research is identified

evidence of eligibility manipulation for conditional cash transfer programs this paper assesses whether eligibility for conditional cash transfer programs has been manipulated as well as the impact of this phenomenon on time allocation within households to perform this analysis we use data from the 2006 pnad brazilian national household survey and investigate the eligibility manipulation for the bolsa familia family stipend program during this time period the program assists families with a monthly per capita income of around r 120 00 us 60 00 by applying the tests developed by mccrary 2008 we find suggestive evidence that individuals manipulate their income by voluntarily reducing their labor supply in order to become eligible to the program moreover the reduction in labor supply is greater among women especially single or divorced mothers this evidence raises some concern about the unintended consequences related to the eligibility criteria utilized by bolsa familia as well as the program s impact on individuals living in extreme poverty 2014 production and hosting by elsevier b v on behalf of national association of postgraduate centers in economics anpec

consumer responses to time varying prices for electricity abstract we report new experimental evidence of the household response to weekday differentials in peak and off peak electricity prices the data come from auckland new zealand where peak residential electricity consumption occurs in winter for heating peak off peak price differentials ranged over four randomly selected groups from 1 0 to 3 5 on average there was no response except in winter in winter participant households reduced electricity consumption by at least 10 took advantage of lower off peak prices but did not respond to the peak price differentials response varied with house and household size time spent away from home and whether water was heated with electricity

demand side vs supply side technology policies hidden treatment and new empirical evidence on the policy mix this paper provides new empirical evidence about the impact of various technological policies upon firms innovative behaviour we take into consideration the role of policies for innovative activities and we focus on their interaction while supply side policies such as r d subsidies and tax credits have been both extensively discussed in the literature and empirically investigated the analysis of innovative public procurement is a growing trend in the literature which still lacks robust empirical evidence in this paper we replicate the existing results on supply side policies surmise fresh empirical evidence on the outcome of innovative public procurement and address the issue of possible interaction among the various tools when controlling for the interaction with other policies supply side subsidies cease to be as effective as reported in previous studies and innovative public procurement seems to be more effective than other tools the preliminary evidence suggests that technology policies exert the highest impact when different policies interact

social implications of residential demand response in cool temperate climates residential electrical demand response dr offers the prospect of reducing the environmental impact of electricity use and also the supply costs however the relatively small loads and numerous actors imply a large effort response ratio residential dr may be an essential part of future smart grids but how viable is it in the short to medium term this paper reviews some dr concepts then evaluates the propositions that households in cool temperate climates will be in a position to contribute to grid flexibility within the next decade and that that they will allow some automated load control examples of demand response from around the world are discussed in order to assess the main considerations for cool climates different tariff types and forms of control are assessed in terms of what is being asked of electricity users with a focus on real time pricing and direct load control in energy systems with increasingly distributed resources the literature points to the significance of thermal loads supply mix demand side infrastructure market regulation and the framing of risks and opportunities associated with dr in concentrating on social aspects of residential demand response the paper complements the body of work on technical and economic potential

public policy towards r d in oligopolistic industries the importance of determining optimal policy towards r d cannot be exaggerated given the worldwide interest in fostering r d and given the significant differences between european and u s policies towards interfirm cooperation on r d moreover the problem is an inherently difficult one because of the complex nature of the r d process since r d is a component of fixed costs industries where it is important tend to be concentrated hence r d policy must go hand in hand with competition policy at the same time r d is like any form of investment in that it precedes the production stage hence issues of time consistency and strategic commitment inevitably arise in considering the choice of r d policy finally r d by one firm typically leads to spillovers wbich benefit other firms so that r d exhibits many of the character department of economics university college dublin belfield dublin 4 ireiatid for helpful discussions and comments we are grateful to two anonymous referees to pedro bartos steve martin massimo motta and damien neven and to participants at seminars in birmingham st andrew s and warwick at a cepr workshop on r d spillovers in lausanne at erwit 94 in caslel gandolfo eea 95 in prague the 1996 conference on industrial economics at universidad carlos iii de madrid and a meeting of the dublin economics workshop this paper was produced as part of the international economic performance programme of the centre for economic performance london school of economics supported by the u k esrc an earlier version was circulated as cepr discussion paper no 1243 see alexis jacquemin 1988 and stephen martin 1996 istics of a public good albeit one that is mostly privately produced tbe degree to which such spillovers occur and can be internalized is another crucial influence on the desirable pattem of intervention
