estimating residential demand for electricity in greece abstract this paper examines the residential demand for electricity in greece the issues of structural stability price and income sensitivity of both long and short run residential demand for electricity in greece were examined employing monthly data over the period 1986 1999 the long run residential demand for electricity is estimated taking into account changes in weather conditions weighted by the size of the population employing multivariate framework analysis a long run residential demand function for electricity sensitive to real income price level and weather conditions is found to exist and the importance of short run deviations is presented using vector error correction model vecm estimation the empirical evidence suggests the presence of a stable residential demand for electricity in greece both in the long and short run periods and the policy implications of such a relationship are presented

technology ecosystem governance technology platform strategies offer a novel way to orchestrate a rich portfolio of contributions made by the many independent actors who form an ecosystem of heterogeneous complementors around a stable platform core this form of organising has been successfully used in smartphone gaming commercial software and industrial sectors technology ecosystems require stability and homogeneity to leverage common investments in standard components but they also need variability and heterogeneity to meet evolving market demand although the required balance between stability and evolvability in the ecosystem has been addressed conceptually in the literature we have less understanding of its underlying mechanics or appropriate governance through an extensive case study of a business software ecosystem consisting of a major multinational manufacturer of enterprise resource planning software at the core and a heterogeneous system of independent implementation partners and solution developers on the periphery o

prices and the winner s curse we usually assume that increases in supply allocation by rationing and exclusion of potential buyers reduce prices but all these activities raise the expected price in an important set of cases when common value assets are sold furthermore when we make the assumptions needed to rule out these anomalies for symmetric buyers small asymmetries among the buyers necessarily cause the anomalies to reappear our results help explain rationing in initial public offerings and outcomes of spectrum auctions we illustrate our results in the wallet game and in another new game we introduce the maximum game

selection of energy performance contracting business models a behavioral decision making approach abstract as a market based mechanism which can actively promote energy efficiency energy performance contracting epc is now universally accepted throughout china and has been incorporated into various business models four of these business models are frequently adopted in china the share savings model the guaranteed savings model the energy cost trust model and the finance lease model the choice of a suitable business model has been recognized as one of the most important factors in the effective implementation of epc projects in this paper the selection of epc business models is formulated as a multi criteria decision making mcdm problem when selecting an epc business model it is natural for decision makers dms to express their preferences opinions in linguistic terms given the characteristics of epc projects taking dms psychological behavior into account is of considerable and realistic significance todim an acronym in portuguese of interactive and multicriteria decision making has been verified as an effective behavioral decision making method to address the problem of epc business model selection an extended todim method based on multi granularity linguistic terms and entropy measure is proposed the sensitivity and comparison analyses show that dms psychological behavior can affect the selection order with respect to the given epc business models one case of a real life campus epc project demonstrates that the validity and applicability of the proposed extended todim method for solving the epc business model selection problem

public private partnerships for energy efficiency projects a win win model to choose the energy performance contracting structure abstract to stimulate private sector investments and promote energy efficiency in recent years through public private partnership arrangements the public sector uses private companies the energy service company esco to perform one or more activities related to the provision of energy services and the contractual arrangements defining the contracting parties obligations and rights are traditionally based on energy performance contracting epc although epc is a valuable model for delivering public energy efficiency projects the adoption is still far from its vast potential mainly because of two unresolved issues the dilemma of equally sharing the benefits between the public and private parties so as assuring a win win condition and the lack of adequate public procedures that support the selection of the most appropriate epc schema given certain circumstances and projects characteristics the existing literature have analyzed the advantages of epc mechanism for delivering energy efficiency projects and explored the critical success factors of epc however it does not provide any solution to address the issues that hamper the adoption of epcs in public sector to fill this gap this paper proposes a model for assessing and benchmarking the net benefits of the different epc structures so as choosing the epc schema that creates a win win solution for both the esco and the government by balancing the private sector s profitability needs and the public sector s economic interests the assessment of the benefits of the epc schema for contractual parties and the benchmark among the contracts are based on an economic approach which expresses the net benefit gained by each party through the three epc contracts in monetary terms and benchmarks the three epc schema through the net present value npv method the win win condition is ensured by the contract that minimizes the difference between the net profits npv gained by the contractual parties this will support the public authority in the decision making process about the epc structure to be adopted to develop an energy efficiency project as a ppp to demonstrate the applicability of the proposed model we apply it to an energy efficiency project launched by the municipality of noci southern italy

a unified presentation of competition analysis in two sided markets the goal of this paper is to present quantitative tools to manage competition policy analysis in two sided platforms based on a common framework for transaction and non transaction platforms we explore tools for relevant market definition critical loss analysis and a small but significant non transitory increase in price ssnip test unilateral effects indicators upward pricing pressure upp and gross upward pricing pressure index guppi and tests for exclusionary practices we review dispersed results in the literature and fill the gaps where appropriate we highlight the required changes from the usual one sided market framework and tools while discussions of antitrust tools can be found in specialized forums devoted to advances in competition policy analysis we organize the material in an integrated framework

the demand for residential electricity in south africa abstract this paper examines the residential demand for electricity in south africa as a function of real gross domestic product per capita and the price of electricity during the period 1978 2005 we make use of the bounds testing approach to cointegration within an autoregressive distributed framework suggested by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 3 289 326 following the literature we use a linear double logarithmic form using income and price as independent variables in the empirical analysis in the long run we find that income is the main determinant of electricity demand while electricity price is insignificant

installed base and compatibility innovation product preannouncements and predation a good is often more valuable to any user the more others use compatible goods the authors show that this effect may inhibit innovation if an installed base exists and transition to a new standard must be gradual early adopters bear a disproportionate share of transient incompatibility costs this can produce excess inertia the installed base however is stranded if the new standard is adopted this may create excess momentum these dynamic effects have strategic implications temporary price cutting can permanently prevent entry and product preannouncements can be critical in innovation these strategic actions have ambiguous welfare effects

platform competition in two sided markets many if not most markets with network externalities are two sided to succeed platforms in industries such as software portals and media payment systems and the internet must get both sides of the market on board accordingly platforms devote much attention to their business model that is to how they court each side while making money overall this paper builds a model of platform competition with two sided markets it unveils the determinants of price allocation and end user surplus for different governance structures profit maximizing platforms and not for profit joint undertakings and compares the outcomes with those under an integrated monopolist and a ramsey planner jel l5 l82 l86 l96

price elasticity block tariffs and equity of natural gas demand in china investigation based on household level survey data abstract on the basis of a newly established database from the chinese residential energy consumption survey this paper estimates the price elasticity of natural gas demand for the households and investigates the factors that affect residential natural gas consumption in china to address the endogeneity problems the non residential natural gas price has been adopted as the instrumental variable for residential natural gas price results demonstrate that the natural gas demand of chinese households respond significantly to price change with an overall price elasticity coefficient of 0 898 in the meanwhile 1 increase in family members would cause 0 159 rise in natural gas demand and household in the south consumes 28 8 more natural gas than that in the north recognizing the heterogeneity of residential natural gas price elasticity for different households quantile regression technique has further been applied to analyze the distributional effect of natural gas consumption the simulation suggests that the gini coefficient drops from 0 49 to 0 40 after introducing an increasing block tariff scheme to replace the original flat tariff system confirming a price reform has potential to improve the energy equity situation by reshaping the energy consumption pattern

the price elasticity of electricity demand in south australia abstract in this paper the price elasticity of electricity demand representing the sensitivity of customer demand to the price of electricity has been estimated for south australia we first undertake a review of the scholarly literature regarding electricity price elasticity for different regions and systems then we perform an empirical evaluation of the historic south australian price elasticity focussing on the relationship between price and demand quantiles at each half hour of the day this work attempts to determine whether there is any variation in price sensitivity with the time of day or quantile and to estimate the form of any relationships that might exist in south australia

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

energy performance contract models for the diffusion of green manufacturing technologies in china a stakeholder analysis from smes perspective abstract small and medium sized enterprises smes are significant to china s emission reduction programme this research aims to improve our understanding of the challenge of diffusing green manufacturing technologies among smes in china specifically this study examines the chinese government s effort to facilitate reduction of energy consumption among smes through energy performance contracts epcs to incentivize domestic manufacturers to adopt energy efficient measures eems in order to reduce demand for energy and corresponding drop in emissions the data is gathered from relevant epc stakeholders in the national motor upgrading demonstration project and its implementation in dongguan city which is based on 30 in depth interviews and 6 focus group discussions using stakeholder analysis this study finds that guaranteed energy savings model is the favorite model in implementation given the gained benefits outweigh committed resources and the control capability overrides possible risks among the two core stakeholders the outcomes of this study may allow the government to have a clear understanding of stakeholder perception of the different epc models used in china so the design and deployment of these mechanisms can be improved

modeling energy demand some emerging issues abstract the proliferation of papers on energy demand modeling has offered different dimensions both in terms of methodology and estimation while this development has strengthened our understanding of the subject it may render the identification of gaps in the literature arduous for future research thus this study sets out to document some emerging issues that seem to have engendered new directions on energy demand modeling ranging from asymmetric price responses time varying demand parameters triangulation analyses to seasonal and climate change effects it is hoped that access to this review complemented with the previous ones will facilitate the comprehension of the extant literature as well as areas of future research in energy demand modeling

chicken and egg competition among intermediation service providers we analyze a model of imperfect price competition between intermediation service providers we insist on features that are relevant for informational intermediation via the internet the presence of indirect network externalities the possibility of using the nonexclusive services of several intermediaries and the widespread practice of price discrimination based on users identity and on usage efficient market structures emerge in equilibrium as well as some specific form of inefficient structures intermediaries have incentives to propose non exclusive services as this moderates competition and allows them to exert market power we analyze in detail the pricing and business strategies followed by intermediation services providers copyright 2003 by the rand corporation

income and price elasticities of electricity demand aggregate and sector wise analyses abstract cointegration and vector error correction modeling approaches are widely used in electricity demand analysis the study rigorously examines the determinants of electricity demand at aggregate and sectoral levels in pakistan in the backdrop of severe electricity shortages our empirical findings give support to the existence of a stable long run relationship among the variables and indicate that electricity demand is elastic in the long run to both income and price at aggregate level at sectoral level long run income and price elasticity estimates follow this pattern except in agricultural sector where electricity demand is found elastic to output but inelastic to electricity price on the contrary the coefficients for income and price are rather small and mostly insignificant in the short run we employed temperature index price of diesel oil and capital stock at aggregate and sectoral levels as exogenous variables these variables account for most of the variations in electricity demand in the short run it shows that mechanization of the economy significantly affect the electricity demand at macro level moreover elastic electricity demand with respect to electricity price in most of the sectors implies that electricity price as a policy tool can be used for efficient use and conservation

switching costs in two sided markets in many markets there are switching costs and network effects yet the literature gen erally deals with these two concepts separately this paper bridges the gap by analyzing their interaction effects or indirect bargain in a dynamic two sided market i show that in a symmetric equilibrium the classic result that the first period price is u shape in switching costs does not emerge but instead switching costs always intensify first period price competition moreover an increase in switching costs on one side decreases the first period price on the other side thus policies that ignore these effects may underestimate the welfare enhancing effects of switching costs

the demand function for residential heat through district heating system and its consumption benefits in korea abstract the demand for residential heat rh through a district heating system dhs has been and will be expanded in korea due to its better performance in energy efficiency and the abatement of greenhouse gas emissions than decentralized boilers the purposes of this paper are two fold the first is to obtain the demand function for dhs based rh in korea and investigate the price and income elasticities of the demand employing the quarterly data covering the period 1988 2013 the short run price and income elasticities are estimated as 0 700 and 0 918 respectively moreover the long run elasticities are 1 253 and 1 642 respectively the second purpose is to measure the consumption benefits of dhs based rh employing the economic theory that they are the sum of the actual payment and consumer surplus for the consumption considering that the average price and estimated consumer surplus of the dhs based rh use in 2013 are computed to be krw 87 870 usd 84 1 and krw 62 764 usd 60 1 per gcal the consumption benefits of the dhs based rh are calculated to be krw 150 634 usd 144 2 per gcal this information can be beneficially utilized to conduct an economic feasibility study for a new dhs project related to rh supply

regulate one service tame the entire market credit cards in turkey abstract in credit card markets banks provide both payment and credit services two regulations were recently enacted in the turkish credit card market one on payment services in 2005 and the other on credit services in 2006 by employing the well known panzar and rosse 1982 panzar and rosse 1987 method and a unique quarterly data set for 21 turkish banks between 2002 and 2008 we investigate the extent of banks market power in the turkish credit card market before and after the regulations unlike most of the existing literature which considers competition and regulation for either credit or payment services and ignores the externalities between them we consider the entire market by taking both services into account fixed effects estimations reveal that banks enjoyed collusive oligopoly power before the regulations although the first regulation did not have much impact the second led to rises in both banks total revenues and competition in the entire market

short and long run elasticities in us residential electricity demand a co integration approach abstract co integration techniques show promise in the analysis of short and long run effects of economic variables on energy use we use these techniques to develop an error correction model of annual us residential electricity demand we construct equipment stock indices and estimate the model for 1949 1993 our analysis suggests a structural shift in consumption during the 1960s we discuss reasons for this shift report the short and long run elasticities provide forecasts for 1994 1995 and compare the model s forecasts with other published forecasts

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

the economic functioning of online drugs markets abstract the economic functioning of online drug markets using data scraped from online platforms is studied analysis of over 1 5 million online drugs sales shows online drugs markets tend to function without the significant moral hazard problems that a priori one might think would plague them only a small proportion of online drugs deals receive bad ratings from buyers and online markets suffer less from problems of adulteration and low quality that are a common feature of street sales of illegal drugs furthermore as with legal online markets the market penalizes bad ratings which subsequently lead to significant sales reductions and to market exit the impact of the well known seizure by law enforcement of the original silk road and the shutdown of silk road 2 0 are also studied together with the exit scam of the market leader at the time evolution there is no evidence that these exits deterred buyers or sellers from online drugs trading as new platforms rapidly replaced those taken down with the online market for drugs continuing to grow

competition between networks a study of the market for yellow pages this paper estimates the importance of network effects in the market for yellow pages i estimate three simultaneous equations consumer demand for usage of a directory advertiser demand for advertising and a publisher s first order condition derived from profit maximizing behaviour estimation shows that advertisers value consumer usage and that consumers value advertising implying a network effect i find that internalizing network effects would significantly increase surplus as an application i consider whether the market benefits from monopoly which takes advantage of network effects or oligopoly which reduces market power i find that a more competitive market is preferable copyright 2004 wiley blackwell

efficiency enhancing taxation in two sided markets this paper examines the efficient provision of goods in two sided markets and characterizes optimal specific and ad valorem taxes we show that i a monopoly may have too high output compared to the social optimum ii output may be reduced by imposing negative value added taxes subsidy or positive specific taxes

technology adoption in the presence of network externalities we analyze technology adoption in industries where network externalities are significant the pattern of adoption depends on whether technologies are sponsored a sponsor is an entity that has property rights to the technology and hence is willing to make investments to promote it key findings include the following 1 compatibility tends to be undersupplied by the market but excessive standardization can occur 2 in the absence of sponsors the technology superior today has a strategic advantage and is likely to dominate the market 3 when one of two rival technologies is sponsored that technology has a strategic advantage and may be adopted even if it is inferior 4 when two competing technologies both are sponsored the technology that will be superior tomorrow has a strategic advantage

cooperation among competitors some economics of payment card associations we analyze platforms in two sided markets with network externalities using the specific context of a payment card association we study the cooperative determination of the interchange fee by member banks the interchange fee is the access charge paid by the merchants banks the acquirers to cardholders banks the issuers we develop a framework in which banks and merchants may have market power and consumers and merchants decide rationally on whether to buy or accept a payment card after drawing the welfare implications of a cooperative determination of the interchange fee we describe in detail the factors affecting merchant resistance compare cooperative and for profit business models and make a first cut in the analysis of system competition

government control of the media abstract we present a formal model of government control of the media to illuminate variation in media freedom across countries and over time media bias is greater and state ownership of the media more likely when the government has a particular interest in mobilizing citizens to take actions that further some political objective but are not necessarily in citizens individual best interest however the distinction between state and private media is smaller large advertising markets reduce media bias in both state and private media but increase the incentive for the government to nationalize private media media bias in state and private media markets diverge as governments become more democratic whereas media bias in democracies and autocracies converge as positive externalities from mobilization increase

on the evolution of market institutions the platform design paradox we study competition among market designers who create new trading platforms when boundedly rational traders learn to select among them we ask whether walrasian platforms leading to market clearing trading outcomes will dominate the market in the long run if several market designers compete we find that traders learn to select non market clearing platforms with prices systematically above the market clearing level provided at least one such platform is introduced by a market designer this in turn leads market designers to introduce non market clearing platforms hence platform competition induces non competitive market outcomes

local network externalities and market segmentation this paper models interaction between groups of agents by means of a graph where each node represents a group of agents and an arc represents bilateral interaction it departs from the standard katz shapiro framework by assuming that network benefits are restricted only amongst groups of linked agents it shows that even if rival firms engage in bertrand competition this form of network externalities permits strong market segmentation in which firms divide up the market and earn positive profits the analysis also shows that some graphs or network structures do not permit such segmentation while for others there are easy to interpret conditions under which market segmentation obtains in equilibrium c 2009 elsevier b v all rights reserved

self selection and the earnings of immigrants this paper analyzes the way in which the earnings of the immigrant population may be expected to differ from the earnings of the native population because of the endogeneity of the decision to migrate the empirical study shows that differences in the u s earnings of immigrants with the same measured skills but from different home countries are attributable to variations in political and economic conditions in the countries of origin at the time of migration excerpt

getting the incentives right energy performance contracts as a tool for property management by local government energy conservation is a challenging and difficult task because disincentives in the building sector inhibit innovation the municipality of rotterdam experimented with an energy performance contract that aimed to avoid disincentives and replace them with a stimulus for innovation this article investigates whether the design requirements for performance management found in the management literature were fulfilled during the development of the contract and its implementation the outcomes of the experiment show substantial energy conservation around 30 percent the existing incentive structure was changed through the use of a performance management contract and perverse effects that are mentioned in the literature were limited the incentives established between the commissioning party and the contractor triggered better performance and innovation although balancing the responsibilities between the principal and the agent was demanding and time consuming energy performance contracts are a useful piece of the sustainability puzzle but tailor made refinements are necessary

should buyers or sellers organize trade in a frictional market to answer the question in the title this article characterizes the socially efficient organization of the market with search frictions the efficient organization depends on the relative elasticity in the supply between the two sides of the market the costs of participating in the market and organizing trade and the a symmetry in matching we also show that the social optimum can be implemented by a realistic market equilibrium where the organizers set up trading sites to direct the other side s search the results provide a unified explanation for why trade has often been organized by sellers in the goods market by buyers firms in the labor market and by both sides in the asset market the analysis also sheds light on how the efficient market organization can change with innovations such as e commerce and just in time production

banking competition and market efficiency this paper analyses competition among financial intermediaries in a set up where financial intermediaries economize on duplicated monitoring diamond 1984 we analyse two different games in which both direct trade and indirect trade are available we show that in general equilibrium outcomes are inefficient so that diamond s efficiency result is fragile intermediation may increase rather than decrease transaction costs disintermediation may also be an equilibrium we discuss the role played by the nonconvexities of banks technology and that played by competition for deposits and loans

residential demand for electricity the case of greece this paper examines the determinants of residential electricity consumption in greece over the period 1961 86 the paper presents first a brief description of the evolution of residential electricity consumption then it proceeds in the estimation of elasticities of residential demand for electricity using a single equation model with the ridge regression method the paper concludes that i the residential demand for electricity is price inelastic and income elastic ii there is high substitutability between electricity and lpg iii during the examined period the number of consumers played a very important role in the expansion of electricity consumption in greece and iv there is no regional variation in residential electricity demand

sensitivity of price elasticity of demand to aggregation unobserved heterogeneity price trends and price endogeneity evidence from u s data abstract price elasticity estimates of residential electricity demand vary widely across the energy economics and policy literature in this paper we seek to explain these findings using three nationwide datasets from the u s the american housing survey forms eia 861 and the residential energy consumption survey we examine the role of the sample period level of aggregation use of panel data use of instrumental variables and inclusion of housing characteristics and capital stock our findings suggest that price elasticities have remained relatively constant over time upon splitting our panel datasets into annual cross sections we do observe a negative relationship between price elasticities and the average price whether prices are rising or falling appears to have little effect on our estimates we also find that aggregating our data can result in both higher and lower price elasticity estimates depending on the dataset used and that controlling for unit level fixed effects with panel data generally results in more inelastic demand functions addressing the endogeneity of price and or measurement error in price with instrumental variables has a small but noticeable effect on the price elasticities finally controlling for housing characteristics and capital stock produces a lower price elasticity

two sided network effects a theory of information product design how can firms profitably give away free products this paper provides a novel answer and articulates trade offs in a space of information product design we introduce a formal model of two sided network externalities based in textbook economics a mix of katz and shapiro network effects price discrimination and product differentiation externality based complements however exploit a different mechanism than either tying or lock in even as they help to explain many recent strategies such as those of firms selling operating systems internet browsers games music and video the model presented here argues for three simple but useful results first even in the absence of competition a firm can rationally invest in a product it intends to give away into perpetuity second we identify distinct markets for content providers and end consumers and show that either can be a candidate for a free good third product coupling across markets can increase consumer welfare even as it increases firm profits the model also generates testable hypotheses on the size and direction of network effects while offering insights to regulators seeking to apply antitrust law to network markets

international entrepreneurship the pursuit of entrepreneurial opportunities across national borders in this editorial for the special issue on international entrepreneurship we inter relate key concepts about the pursuit of opportunities from the entrepreneurship and international business literatures in doing so we consider the assessment of opportunities as an individual level cognitive activity the construction of opportunity as a firm level innovative activity and the shaping of opportunity as an institutional level structuring activity we then extend the discussion to explore the notion of a distributed global ecosystem of opportunities and opportunity seekers which we believe may provide a platform for valuable future research

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

ownership and control rights in internet portal alliances 1995 1999 we examine the structure of more than 100 alliances by internet portals and other firms between 1995 to 1999 from a contract theory perspective models of incomplete contracts frequently invoke unforeseen contingencies the cost of writing contracts and the cost of enforcing contracts in justifying the assumption of incompleteness the setting in which internet portals formed alliances was rife with these sorts of transaction costs we argue that these alliances can be viewed as incomplete contracts and find that the division of ownership and the allocation of control rights are consistent with the incomplete contracting literature copyright 2003 by the rand corporation

platform pricing at sports card conventions platform pricing at sports card conventions we study a new data set of us sports card conventions in order to evaluate the pricing theory of two sided markets conventions are two sided because organizers must set fees to attract both consumers and dealers we have detailed information on consumer price dealer price and since most conventions are local the market structure for conventions we present several findings first consumer pricing decreases with competition at any reasonable distance but pricing to dealers is insensitive to competition and in longer distances even increases with competition second when consumer price is zero and thus constrained dealer price decreases more strongly with competition these results are compatible with existing models of two sided markets but are difficult to explain without such models

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

an econometric analysis of the drivers for residential heating consumption in the uk and germany abstract affecting millions of europeans energy poverty is increasingly high on the political agenda this paper compares space and water heating demand at household level in germany and in the united kingdom uk between 1991 and 2015 the elasticities of consumption of space and water heating with respect to price income and heating degree days hdd are examined using non parametric models domestic heating consumption is highly elastic with hdd in both countries and hdd elasticities are found to be higher in the uk from a certain income threshold heating demand decreases as income increases in german households whereas demand rises with higher incomes in the uk high price elasticities indicate that uk households are very responsive to energy conservation measures therefore implying that a pricing policy will effectively reduce heating consumption however in germany the impact of pricing policies is unclear thus the most effective policy measure to decrease domestic heating consumption in germany in the long run should be one which targets improvements of building envelope performance levels

systems competition and network effects this paper discusses firm behavior market performance and the public and private institutions that arise in systems markets i e markets where consumers use compatible components together to generate benefits in such markets which include communications networks and hardware software networks popular products are inherently more valuable these network effects can drive corporate strategies and are critical in understanding innovation in many high technology markets the discussion here emphasizes the dynamics of consumer adoption decisions in the presence of network effects competition between incompatible systems and how suppliers choose which components are compatible and which are not

estimating short and long term residential demand for electricity new evidence from sri lanka this study investigates the short run dynamics and long run equilibrium relationship between residential electricity demand and factors influencing demand per capita income price of electricity price of kerosene oil and price of liquefied petroleum gas using annual data for sri lanka for the period 1960 2007 the study uses unit root cointegration and error correction models the long run demand elasticities of income own price and price of kerosene oil substitute were estimated to be 0 78 0 62 and 0 14 respectively the short run elasticities for the same variables were estimated to be 032 0 16 and 0 10 respectively liquefied petroleum lp gas is a substitute for electricity only in the short run with an elasticity 0 09 the main findings of the paper support the following 1 increasing the price of electricity is not the most effective tool to reduce electricity consumption 2 existing subsidies on electricity consumption can be removed without reducing government revenue 3 the long run income elasticity of demand shows that any future increase in household incomes is likely to significantly increase the demand for electricity and 4 any power generation plans which consider only current per capita consumption and population growth should be revised taking into account the potential future income increases in order to avoid power shortages ill the country

competitive dialogue procedure for sustainable public procurement the construction sector has adopted green public procurement to improve its environmental performance green public procurement is a process whereby contracting authorities aim to procure services and products that meet environmental requirements in recent years green public procurement has extended to sustainable public procurement which involves the incorporation of both environmental and social considerations in the procurement of goods and services previous studies have suggested the relevance of contractor engagement strategies and the need for appropriate models to promote dialogue in sustainable public procurement this paper illustrates one such model called the competitive dialogue procedure this newly introduced procurement procedure allows the contracting authority to hold discussions with shortlisted contractors regarding the authority s requirements the paper uses the practical case of the kvarnholmen link project in sweden the kvarnholmen link is an infrastructure project that includes the construction of a bridge tunnel underpass and pedestrian and bike path action research was conducted to examine the competitive dialogue procedure this paper has strengthened the conceptualisation that the procedure can facilitate sustainable public procurement with the aid of its key elements such as provisionally preferred solution and dialogue sessions in addition the paper analyses the consequences of the weight used for environmental considerations in the bid evaluation process this paper recommends that contracting authorities implementing competitive dialogue procedure must use provisionally preferred solution to identify sustainable public procurement preferences dialogue sessions with contractors should involve discussions regarding sustainable public procurement to ensure consistency between the weight for environmental considerations and respective preferences

information gatekeepers on the internet and the competitiveness of homogeneous product markets we examine the equilibrium interaction between a market for price information controlled by a gatekeeper and the homogenous product market it serves the gatekeeper charges fees to firms that advertise prices on its internet site and to consumers who access the list of advertised prices gatekeeper profits are maximized in an equilibrium where a the product market exhibits price dispersion b access fees are sufficiently low that all consumers subscribe c advertising fees exceed socially optimal levels thus inducing partial firm participation and d advertised prices are below unadvertised prices introducing the market for information has ambiguous social welfare effects

environmental value chain in green sme networks the threat of the abilene paradox abstract demand side policies are an important complement to subsidies in fostering green product service markets green public procurement gpp in particular presents valuable characteristics in terms of directionality volumes and measurability despite being widely analysed from a public perspective gpp development is still under explored from a corporate point of view to shed some light on the strategic attitude of firms towards gpp this paper discusses an exploratory research in the field of road construction an inductive analysis of direct observations and theoretical contributions suggests the potential for the so called abilene paradox to hamper gpp opportunities for small and medium enterprises in fact in times of crisis increased pressures to improve performance and reduce risk resistance to change and strategic myopia can easily impair inter organizational interactions and thus prevent potentially innovative networks from pressuring public investments in green supply chains the related policy suggestions represent a first attempt to enter the realm of systemic approaches to gpp

estimation of japanese price elasticities of residential electricity demand 1990 2007 abstract this paper estimates elasticities of japanese residential price electricity from 1990 to 2007 the first difference generalized method of moment estimator is employed to avoid dynamic panel bias which is not considered in most previous studies the results show that while short run elasticities are similar to those in previous studies long run elasticities are significantly lower in our study we also find that the price elasticity of japanese residential electricity consumption is notably affected by income inequality and severe weather based on these results we provide some insights to tailor environmental taxation so as to effectively attain the kyoto protocol
