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

comparing systems approaches to innovation and technological change for sustainable and competitive economies an explorative study into conceptual commonalities differences and complementarities this paper makes a distinction between three theoretical frameworks that have been highly influential in the discourse on innovation competitiveness and sustainability sectoral systems of innovation ssi technological innovation systems tis and socio technical systems st systems these frameworks share a common systems approach to innovation but are often positioned as different bodies of literature that correspond to different epistemic communities this paper is explorative and conceptual in nature it presents a systematic comparative review of ssi tis and st systems based on the following analytical dimensions 1 system boundaries 2 actors and networks 3 institutions 4 knowledge 5 dynamics and 6 policy approach in the concluding section commonalities and differences of the three approaches are presented and suggestions for complimentarily are made c 2010 elsevier ltd all rights reserved

a note on sequential auctions this note provides an explanation for the declining price anomaly in sequential second price auctions we illustrate how the average winning bids of risk neutral agents bidding for objects with valuations drawn from independent identical distributions are lower in later auctions than in earlier auctions when the objects are not identical we determine the optimal order in which they should be auctioned

the contractors game we develop a symmetric information auction model of multiproject contracting with costly bidding and increasing marginal performance costs when there are many potential contractors or only one job there is a zero expected profit symmetric equilibrium in mixed strategies the winning bid at this equilibrium tends to rise perversely with the number of contractors when there are only two potential bidders and either two or three jobs multiple bids of a contractor at equilibrium are negatively correlated with each other the resulting equilibrium outcome tends to divide the market between the contractors in a manner that suggests anticompetitive behavior despite the absence of any collusion

how might china achieve its 2020 emissions target a scenario analysis of energy consumption and co2 emissions using the system dynamics model abstract according to the chinese government s co 2 reduction commitment the production and consumption of traditional and renewable energy in china from 2001 to 2012 this paper forecasts the energy consumption gross co 2 emissions and co 2 emission intensity in china from 2013 to 2020 via system dynamics simulation coupled with the energy system and renewable energy policy factors the effects of different economic growth rates and policy factors on the energy consumption were estimated the results showed that in different economic growth rates scenarios total energy consumption and co 2 emissions increased by 36 140 75 kwh and more than 10 000 billion kg in 10 gdp growth rate scenario than in the 7 scenario in 2020 the co 2 emission per gdp decreased by 52 in 2020 as compared to 2005 under the scenario of 10 gdp growth rate under different renewable energy policy factors scenarios the coal energy consumption decreased by 2 3 in scenario of 5 policy factor as compared to 1 policy factor scenario the co 2 emissions reduced by 3321 94 billion kg in 2020 under the scenario of 5 policy factor as compared to that in the scenario of 1 policy factor the co 2 emission per gdp reduced by 47 50 based on the 2005 level in different scenarios of renewable energy policies we found that with an increase in gdp total energy consumption and co 2 emissions increased in the base scenario higher economic growth rates led to an increase in energy consumption including both the traditional and renewable energy resources in stark contrast to total co 2 emission however co 2 emission intensity decreased with an increase in economic growth rate the renewable energy policy improved the renewable energy development reduced co 2 emissions and co 2 emission intensity it was more effective in energy saving and co 2 reduction than the high growth rate scenarios the results indicated that china is highly likely to achieve its co 2 emission reduction goal under different simulated scenarios besides the energy distribution was similar in different scenarios coal was the major energy source which amounted to more than 70 of the total energy consumption finally we conclude with important policy implications according to our simulations results

determinants of environmental investments testing the structural model abstract the main purpose of this study is to provide the needed additional quantitative evidence regarding the introduction of environmental technologies and to increase the possibility for generalization and thus policy application of conclusions to achieve that purpose a conceptual model is developed and then tested on a large database of firms from various industries with the use of structural equation modeling the results show that policy measures past environmental investments the importance of environmental technologies for customers and the firm performance have a positive effect on environmental investments furthermore the results show that policy measures are a second order three factor construct

the declining price anomaly abstract data from wine auctions indicate that identical products sold sequentially typically follow a decreasing pattern of prices known as the declining price anomaly this is explained for both first and second price auctions by appealing to risk averse bidders earlier bids are then equal to expected later prices plus a risk premium associated with the risky future price we show that this logic rests on the assumption of nondecreasing absolute risk aversion which is necessary for pure strategy equilibrium bidding functions to exist thus decreasing absolute risk aversion implies ex post inefficiency with positive probability data from wine auctions are used to confirm the existence of the declining price anomaly journal of economic literature classification numbers d43 d44 d81 d82 l81

new approaches to cleaner production applying the sasi method to micro tanneries in colombia the literature on micro and small sized enterprises in developing countries shows their existential difficulties this is particularly true for those in marginal areas with multiple challenges including pollution prevention environmental agencies tend to require capital intensive end of pipe solutions or regulatory measures that close down polluting enterprises both knowledge of and interest in how to make poor micro enterprises more sustainable are needed this paper addresses this by a developing a problem driven and context oriented systematic approach to social inclusion sasi method and b applying it successfully in the context of micro tanneries in villapinzon colombia over a period of eight years the concept of cleaner production was systematically integrated into this method that was inspired by lewin s theory of change and insights from negotiation and conflict resolution the results show that cleaner production implementation needs comprehensive systemic policy mechanisms based on participatory approaches taking into account the socio economic constraints of the micro industries that combine supportive capacity building and command and control policies moreover rules encouraging cleaner production need to be sensitive to the regulatory context in which it is applied which in this case concerned land use planning and zoning regulations the sasi approach effectively encouraged micro tanners to make their industries more viable and clean while it simultaneously convinced the environmental agency to recognise and value these industries this paper argues that integrating cleaner production in sasi is a learning and socio technical change process urgently needed for micro industries

how auctions work for wine and art interview auctioneers and even to buy a little wine in the meantime i have also had the opportunity with john abowd 1988 to observe and collect data on the auction sale of impressionist and contemporary paintings this paper reports on some of the empirical regularities that i and others have observed in the actual operation of the auction markets for these items in view of the rich and diverse array of theoretical literature on auctions it seems high time economists began to spell out precisely what facts it is meant to explain 2

application of a system dynamics approach for assessment of the impact of regulations on cleaner production in the electroplating industry in china abstract compared with pollution transfer cleaner production cp is more effective to reduce heavy metal pollution in many less developed countries however it s more difficult to develop an efficient policy to make enterprises to completely invest in cp this paper analyses the effects of cp policies on investment decisions of firms using a dynamic systems model and by simulating a typical electroplating enterprise in shenzhen china results show that water price could be effective only when it is increased by a sufficient amount for instance only when it is increased directly from 2 to 8 cny m 3 0 3 1 2 usd m 3 or from 8 to 16 cny m 3 1 2 2 5 usd m 3 will an enterprise gradually increase cp investment from process modification to recovery technology increasing the metal utilization rate of cp standard plating and surface finishing industry from its current value of 75 85 would encourage an enterprise to add recovery technology uniform preferential tax rate and penalties for the three parts of cp do not affect investment decisions on cp using the same investment subsidy rate for the three parts of cp could be effective in promoting cp only if it is above 60 the current emission standard of metal has played a role in promoting cp a comparison of three possible strategies indicates that a distinct policy for the different parts of cp is the optimal policy combination an overall investigation of typical enterprises based on the abovementioned framework is suggested to make more practical policies which than can promote cp instead of pollution transfer

sustainable production and consumption systems cooperation for change assessing and simulating the willingness of the firm to adopt develop cleaner technologies the case of the in bond industry in northern mexico abstract over the last decade literature on the greening of industry and environmental policy has provided numerous important insights into the determinants of the firm s innovative behaviour in cleaner technologies however this literature still lacks empirically tested theoretical models this paper contributes to fill this gap proposing a definitional system that enables the testing of hypotheses of dependence between willingness to innovate in cleaner technologies and its determinants and to explore the conditions under which the firms innovative behaviour could be fostered regression and simulation outcomes indicate against the general wisdom that stringent environmental regulation without consideration to the dynamics of technical change and environmental and economic risk perceptions in the part of firms would play against the promotion of innovation in cleaner production

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

total factor productivity differences appropriate technology vs efficiency abstract recent development and growth accounting studies have established that total factor productivity is an important source of cross country differences in income levels and growth rates this paper makes two contributions first it examines the sensitivity of the development accounting results to the cobb douglas specification of the production function second within the cobb douglas framework it weighs evidence of the two alternative explanations of total factor productivity differences the inefficiency view and the appropriate technology view to accomplish these tasks the world production frontier is estimated using a nonparametric deterministic approach known as data envelopment analysis i find that the fraction of income differences explained by physical and human capital increases from 32 to 55 when departing from the cobb douglas assumption there is also evidence consistent with the appropriate technology view countries with an inadequate mix of inputs are unable to access the most productive technologies moreover the world technology frontier appears to be shifting out faster at input combinations close to that of the rd it explains 43 of output variation in 1995 and its importance has increased over time

reputation in repeated second price auctions abstract a model in which two bidders take part in a series of second price comon value auctions is examined the question of an optimal auction from an auctioneer s standpoint in a repeated auction setting is partially addressed it is shown that the results from single auction models do not carry over to repeated auctions when one of the bidders is endowed with a reputation for bidding aggressively second price auctions with two bidders are highly susceptible to manipulative behaviour by an aggressive bidder and yield much lower revenues to the auctioneer

the ambiguity of innovation drivers the adoption of information and communication technologies by public water utilities abstract information and communication technologies have the potential to increase productivity improving efficiency and eventually raising the quality of water services although this potential is recognized great variation exists in the way water utilities adopt information and communication technologies based on literature review and empirical data drawn from the three case studies a municipality in greece an airport in italy and a water utility in the netherlands developed under the eu funded waternomics project the paper highlights how environmental organizational and individual factors explain technology adoption the paper pays particular attention to the idiosyncrasies of the water services sector which influence this process these include include the social and conomic importance of water supply the monopolistic nature of the sector and increased commercialization of public water utilities our cases suggest that drivers of technology adoption appear to be somewhat ambiguous in the water services sector in that they impact adoption in diverse locations differently our cases also suggest is that the prioritization of the factors that determine adoption are dynamic and change over time

models of technology diffusion abstract the literature on new technology diffusion is vast and it spills over many conventional disciplinary boundaries this paper surveys the literature by focusing on alternative explanations of the dominant stylized fact that the usage of new technologies over time typically follows an s curve the most commonly found model which is used to account for this model is the so called epidemic model which builds on the premise that what limits the speed of usage is the lack of information available about the new technology how to use it and what it does the leading alternate model is often called the probit model which follows from the premise that different firms with different goals and abilities are likely to want to adopt the new technology at different times in this model diffusion occurs as firms of different types gradually adopt it there are actually many ways to generate an s curve and the third class of models which we examine are models of density dependence popularized by population ecologists in these models the twin forces of legitimation and competition help to establish new technologies and then ultimately limit their take up finally we look at models in which the initial choice between different variants of the new technology affect the subsequent diffusion speed of the chosen technology such models often rely on information cascades which drive herd like adoption behaviour when a particular variant is finally selected

defining the inventor entrepreneur in the context of established typologies abstract some 25 years ago while developing his type of entrepreneur and type of firm classification system smith 1967 thought he had identified a subtype of entrepreneur that did not fit either his craftsman or his opportunistic models the data at that time were too sparse to be sure but it appeared that there were certain entrepreneurs whose major concern was to develop an organization not as an end in itself as with the opportunistic type but rather as a vehicle to allow the invention and production of various products this research now provides much more convincing evidence that the inventor entrepreneur does indeed exist using a sample of 147 national science foundation grant applicants who are also entrepreneurs this sample was deemed particularly likely to contain large numbers of inventor entrepreneurs the support for smith s 1967 early speculations turns out to be rather amazing the inventor entrepreneurs are located exactly where smith 1967 expected them to be in the type of entrepreneur versus type affirm matrix as anticipated inventor entrepreneurs like other entrepreneurs are more likely to head growing companies to the extent that they themselves are of the opportunistic type and their firms are of the adaptive type there is nothing in the inventor entrepreneur concept alone that calls for company growth also as hypothesized the presence of a large number of inventor entrepreneurs in a sample tends to dilute the usual finding of a strong positive correlation between type of entrepreneur and type of firm measures among inventor entrepreneurs it is not necessarily true that opportunistic entrepreneurs tend to head adaptive firms and craftsman entrepreneurs head rigid ones there was one unexpected finding however smith 1967 originally associated the inventor entrepreneur with a proclivity for taking out patents although this association is supported by this research it is dwarfed by another factor what is really indicative of inventor entrepreneurship is a strong commitment to a company strategy of new product development although not established by this research it would appear that increasingly those who invent are dissuaded from seeking patents by the costs involved the time delays and the prospect in many new industries that patents will provide very little protection it seems likely that patents will continue to decline in popularity among inventor entrepreneurs and that rapid market entry with new products to become a market leader will be the preferred strategy of the future this assumes of course that inventor entrepreneurs have access to sufficient capital to pursue this new product development strategy effectively investors should recognize however that the real importance of the inventor entrepreneur stems not so much from immediate profit potential and the prospects for asset growth although these are there as from the contributions these individuals make to an expanding economy and the well being of society

ignorance promotes competition an auction model with endogenous private valuations we study a situation in which an auctioneer wishes to sell an object toone of n risk neutral bidders with heterogeneous preferences theauctioneer does not know bidders preferences but has private informationabout the characteristics of the ob ject and must decide how muchinformation to reveal prior to the auction we show that the auctioneerhas incentives to release less information than would be efficient andthat the amount of information released increases with the level ofcompetition as measured by the number of bidders furthermore in aperfectly competitive market the auctioneer would provide the efficientlevel of information

cleaner technology diffusion case studies modeling and policy abstract the development and application of cleaner technologies environmental technologies offer multiple benefits for the adopter reduced emissions less waste and cost savings from reduced resource use and savings on waste costs the question here is if cleaner technologies offer such great benefits why they are diffusing so slowly across the economy this special issue is about answering this question by presenting a collection of contributions that lay down a good foundation for students scholars practitioners and policy makers interested in making sustainable development more than a metaphor the contributions range from surveys of literature identifying gaps and directions in the field cleaner technology diffusion case studies advances in diffusion modeling and diffusion policy issues and recommendations in general the set of papers present an overview of the advances in the field of cleaner technologies diffusion research

on some myths about sequenced common value auctions abstract equilibria are constructed for classes of game models of sequenced second price auctions having identical common valued objects in some of these the equilibrium price falls on average and in others the seller loses on average by committing to announce publicly something that he knows both of these possibilities are surprises journal of economic literature classification number d44

a theoretical analysis of optimal financing strategies for different types of capital constrained entrepreneurs in this paper we compare two alternative financing strategies that capital constrained entrepreneurs can adopt they can either wait until they raised enough money to complete their project the more conservative strategy or use limited resources to achieve some intermediate milestone before contacting large outside investors such as venture capitalists the more adventurous strategy we examine how the choice of financing strategy is affected by entrepreneurial types life style serial and pure profit maximizing entrepreneur we show that specific entrepreneurial characteristics may ultimately affect the shape of firms as they may pursue different strategies to achieve similar goals the paper generates a number of empirical predictions on security design the interplay between angel and venture capital finance and the professionalization of the venture capital market c 2006 elsevier inc all rights reserved

simultaneous auctions with synergies and common values abstract in this paper we study a simultaneous auction model with synergies common values and overlapping interests we construct strategies in which bidders of different types randomize over different bid intervals and provide necessary and sufficient conditions for such strategies to form symmetric equilibria questions about seller s revenue and efficiency are addressed journal of economic literature classification number d44
