the optimal auction a mechanism for optimal third degree price discrimination abstract recently bulow and roberts have indicated that there is a close correspondence between the optimal auction mechanism introduced by myerson and the problem of a monopolist practising third degree price discrimination in several markets they find differences however in the choice variables and in the constraints of the two problems a reinterpretation of the price discrimination problem leads to the demonstration that an optimal auction is an optimal way to practise price discimination

effects of oil price shocks on the stock market performance do nature of shocks and economies matter the main focus of this study is to examine how oil price fluctuations influence the performance of stock markets this study used the causality approach developed by toda and yamamoto 1995 to explore the causality between oil prices and stock prices in the long run and their short term impact the generalized impulse response functions were applied to the monthly data in the period from january 1997 to july 2013 in this study to capture the different characteristics of oil refining exporting and importing three asian economies were examined the results indicate that the manner in which a market reacts to hikes in oil prices varies between different markets and periods this depends on differences in the oil characteristics of the economy and the nature of the shock in oil prices

on the impacts of oil price fluctuations on european equity markets volatility spillover and hedging effectiveness the objective of this paper is to investigate the volatility spillovers between oil and stock markets in europe as not all industries are expected to be equally affected by oil price changes we conduct our study at both the aggregate as well as sector levels empirically we make use of a recently developed var garch approach which allows for transmissions in volatilities in addition we analyze the optimal weights and hedge ratios for oil stock portfolio holdings based on our results on the whole our findings show significant volatility spillovers between oil price and sector stock returns and suggest that a better understanding of those links is crucial for portfolio management in the presence of oil price risk

effect of information feedback on bidder behavior in continuous combinatorial auctions combinatorial auctions in which bidders can bid on combinations of goods can increase the economic efficiency of a trade when goods have complementarities recent theoretical developments have lessened the computational complexity of these auctions but the issue of cognitive complexity remains an unexplored barrier for the online marketplace this study uses a data driven approach to explore how bidders react to the complexity in such auctions using three experimental feedback treatments using cluster analyses of the bids and the clicks generated by bidders we find three stable bidder strategies across the three treatments further these strategies are robust for separate experiments using a different setup we also benchmark the continuous auctions against an iterative form of combinatorial auction the combinatorial clock auction the enumeration of the bidding strategies across different types of feedback along with the analysis of their economic implications is offered to help practitioners design better combinatorial auction environments this paper was accepted by lorin hitt information systems

multiple round timber auction design and simulation this paper presents a multiple round timber auction simulation developed in order to study various configurations of auction design in this study simultaneous sequential timber auctions are modelled and analysed using agent based simulation technology as there are many individual items in the auction to be sold the auction designer defines several rounds that are sequential at pre defined intervals at each round the auction designer announces several simultaneous auctions since bidders are offered different items at each round a mathematical linear programing model for selecting the best set of items to bid for is presented different bidding patterns are simulated and compared in various setup configurations the most advanced of these strategies are adaptive and use agent learning capability the comparisons include the success rate of winning the auction and the winning price per m3 this study suggests an efficient bidding pattern for bidders to bid in order to achieve to their goal and increase their profit similarly in order to increase profit the auctioneer i e the government needs to control several auction parameters including the number of auctions per year the lot size the auction periodicity and the number of bidders this study also suggests parameters configurations that to maximise revenue for the auctioneer

uniform vs discriminatory auctions with variable supply experimental evidence in the variable supply auction considered here the seller decides how many customers with unit demand to serve after observing their bids bidders are uncertain about the seller s cost we experimentally investigate whether a uniform or a discriminatory price auction is better for the seller in this setting exactly as predicted by theory it turns out that the uniform price auction produces substantially higher bids and consequently yields higher revenues and profits for the seller furthermore again as predicted by theory the uniform price auction yields a higher number of transactions which makes it also the more efficient auction format

period specific volatility spillover based connectedness between oil and other commodity prices and their portfolio implications abstract this paper analyses the changing impact of oil price shocks on a bouquet of metal and agro prices and their implications for investment decisions during different oil price regimes separated by structural breaks endogenously identifying the structural breaks we use network analysis to decipher the nature and extent of such shock transfer across different sub periods we suggest optimal portfolios based on conditional variance estimates to hedge oil shocks during each period this is the first study to analyse the portfolio decisions during specific oil price regimes the results are of significant interest to investors and policy makers

dynamic cyclical comovements of oil prices with industrial production consumer prices unemployment and stock prices abstract this paper examines the empirical relationship between oil prices and several key macroeconomic variables in particular we investigate the cyclical comovements of crude oil prices with output consumer prices unemployment and stock prices the methodology involves the use of the hodrick prescott hodrick r j prescott e c 1980 post war us business cycles an empirical investigation working paper carnegie mellon university and baxter king baxter m king r g 1999 measuring business cycles approximate band pass filters for economic time series review of economics and statistics 81 575 593 filters as well as the recently developed full sample asymmetric christiano fitzgerald christiano l j fitzgerald t j 2003 the band pass filter international economic review 44 435 465 band pass filter contemporaneous and cross correlation estimates are made using the stationary cyclical components of the time series to make inference about the degree to which oil prices move with the cycle besides documenting a number of important cyclical relationships using three different time series filtering methods the results suggest that crude oil prices are procyclical and lag industrial production additionally we find that oil prices lead consumer prices

managing online auctions current business and research issues the internet s computational power and flexibility have made auctions a widespread and integral part of both consumer and business markets though online auctions are a multi billion dollar annual activity with a growing variety of sophisticated trading mechanisms scientific research on them is at an early stage this paper analyzes the current state of management science research on online auctions it develops a broad research agenda for issues such as the behavior of online auction participants the optimal design of online auctions the integration of auctions into the ongoing operation of firms and the use of the data generated by online auctions to inform future trading mechanisms these research areas will draw from applied and theoretical work spanning management science economics and information systems

extreme risk spillovers between crude oil and stock markets abstract this paper investigates the spillovers of extreme risks between crude oil and stock markets using daily data of the s p 500 stock index and west texas intermediate wti crude oil futures returns based on the method of granger causality in risk value at risk var is employed to measure market risk and a class of kernel based tests is used to detect negative and positive risk spillover effects empirical results reveal that there are significant risk spillovers between the two markets extreme movements past or current in one market may have a significant predictive power for those in the other market prior to the recent financial crisis there are positive risk spillovers from stock market to crude oil market and negative spillovers from crude oil market to stock market after the financial crisis bidirectional positive risk spillovers are strengthened markedly the risk spillovers may occur instantaneously and or with a long time delay both positive and negative risk spillover effects exhibit asymmetric correlations

a test that discriminates between two models of the dutch first auction non isomorphism abstract previous experiments reject the hypothesis that the dutch and first auctions are isomorphic two alternatives to the standard normal form analysis of the dutch auction are formalized 1 bidders violate bayes rule 2 bidders experience a utility of suspense that is additive with the utility of monetary reward paired comparisons of bidding behavior between groups in which the treatment is to triple the payoff of the baseline group yields no significant effect of this treatment we therefore reject the utility of suspense model

collusive bidder behavior at single object second price and english auctions models of collusive bidder behavior at single object second price and english auctions are provided the ind ependent private values model is generalized to permit the formulatio n of coalitions and a strategic response by the auctioneer cooperati ve strategies are found to be dominant in these models coalitions of any size are viable and the payoff to each member increases with th e size of the coalition in addition the collusive strategies of the coalition represent a noncooperative equilibrium the optimal respon se of the auctioneer is to establish a reserve price that is a functi on of the coalition s size these and other features of the model are found to be consistent with the essential features of actual behavio r copyright 1987 by university of chicago press

high yield bond and energy markets abstract high yield bonds hold a particularly unique space in the debt market from many aspects literature suggests these assets to behave more like stocks than bonds given the significant similarities between the high yield bond and stock markets it is expected for these markets to be similarly affected by certain outside factors some shocks including the ones from energy markets are known to impact the entire stock market and not just related company shares since high yield bond portfolios include some amount of energy company debt the recent volatility in energy prices has been particularly concerning to market participants however the question of whether price and volatility shocks only impact energy company bonds or the entire high yield bond market as they do with the stock market still remains unanswered this study attempts to address that question by exploring the dynamic relationships between the high yield bond and energy markets price transmission tests which account for gradual structural shifts suggest oil and ethanol markets significantly impacting the high yield bond market furthermore volatility tests find uni directional volatility transmitting from energy markets to the high yield bond market

discriminatory public procurement policy and cost reduction incentives abstract discriminating in favor of domestic suppliers in the award of government procurement contracts is a widespread practice in this paper we extend the previous analysis of mcafee and mcmillan 1989 government procurement and international trade journal of international economics 26 291 308 and branco 1994 favoring domestic firms in procurement contracts journal of international economics 37 65 80 by considering in the same model the bidding competition stimulation effect and the favoritism effect we prove that the optimal policy can be implemented by a modified vickrey auction or by a complex modified first price auction we also consider that firms can reduce their cost by a nonobservable effort we show that taking moral hazard into account does not modify the awarding rule but that the government must use the payment rule to require a greater level of effort from the favored firm

multiattribute elicitation of wilderness preservation benefits a constructive approach abstract this paper contributes to the development of a constructive approach to evaluating environmental resources using a version of multiattribute value elicitation in a group setting section 1 discusses the assumptions and practices of group multiattribute elicitation for public policy decisions the good of interest is a potential doubling of designated wilderness areas in british columbia two groups totalling 28 subjects participated in intensive half day workshops in which they provided judgments regarding the amounts of tax revenues from forest industry activities each thought provincial residents should forego to achieve specified increases in wilderness preservation subjects were asked to consider direct and passive use values spiritual values and ecological service values subjects were also asked to consider separately the interests of the current generation and future generations of residents and to provide judgments regarding the marginal benefits of increasing preservation an initial aggregated valuation question was followed by five more disaggregated questions subjects then compared and reconciled their value judgments for the aggregated and disaggregated questions the results are generally comparable to those of a contingent valuation referendum based survey for the same valuation issues

economic growth and energy consumption causal nexus viewed through a bootstrap rolling window one puzzling results in the literature on energy consumption economic growth causality is the variability of results particularly across sample periods sample sizes and model specification in order overcome these issues this paper analyzes the causal links between energy consumption and economic growth for g 7 countries using bootstrap granger non causality tests with fixed size rolling subsamples the data used includes annual total energy consumption and real gross domestic product gdp series from 1960 to 2006 for g 7 countries excluding germany for which the sample period starts from 1971 using the full sample bootstrap granger causality test we find that there is predictive power from energy consumption to economic growth only for canada however parameter instability tests show that none of the estimated models have constant parameters and hence the full sample results are not reliable analogous to the full sample results the results obtained from the bootstrap rolling window estimation indicate no consistent causal links between energy consumption and economic growth we however find that causal links are present between the series in various subsamples furthermore these subsample periods correspond to significant economic events indicating that the findings are not statistical artefacts but correspond to real economic changes our results encompass previous findings and offer an explanation to varying findings

costly bidding in online markets for it services internet enabled markets are becoming viable venues for procurement of professional services we investigate bidding behavior within the most active area of these early knowledge markets the market for software development these markets are important both because they provide an early view of the effectiveness of online service markets and because they have a potentially large impact on how software development services are procured and provided using auction theory we develop a theoretical model that relates market characteristics to bidding and transaction behavior taking into account costly bidding we then test our model using data from an active online market for software development services which yields contracts for 30 40 of posted projects in its current format however the studied market may induce excessive bidding by vendors consistent with our theoretical predictions and those of carr 2003 higher value projects attract significantly more bids with lower average quality greater numbers of bids raise the cost to all participants due to costly bidding and bid evaluation perhaps as a consequence higher value projects are also much less likely to be awarded

auctions an introduction abstract this is a detailed introduction to auction theory it begins with a simple analysis of standard auctions and then uses a strikingly simple general solution of symmetric private values auctions to prove the payoff equivalence of many auction rules the basic framework is then modified to admit risk aversion multi unit and repeated auctions as well as collusion then follows an introduction to optimal auctions with and without stochastic entry and to common value auctions and the winner s curse problem the survey closes with a sample of applications from the regulation of natural monopolies to price competition in oligopoly and the government securities market

discourse based valuation of ecosystem services establishing fair outcomes through group deliberation discourse based methods involving small groups of citizens have yet to be thoroughly engaged in the practice of ecosystem valuation this remains true despite the fact that many ecosystem goods and services such as clean air biodiversity and unpolluted lakes and rivers are considered to be public goods the conventional application of ecosystem valuation relies heavily on methodologies such as contingent valuation in which individuals are asked to express the value they attach to ecosystem goods and services in social isolation the difference between the public nature of ecosystem services and their valuation through individual expression has thus recently led to calls for more deliberative forms of environmental valuation because the allocation of ecosystem services directly affects many people and raises normative questions about social equity it is argued that carefully designed discursive methods will help ensure the achievement of social equity goals in this paper we examine the theoretical and normative assumptions that rest beneath the proposed turn towards discourse based methods and identify procedures for testing their application in the field 2002 elsevier science b v all rights reserved

dynamic spillovers among major energy and cereal commodity prices abstract over the past decade the sharp increases in the prices of oil and agricultural commodities have raised serious concerns about the heightened volatility of these markets and the possible negative interactions between them this article deals with the dynamic return and volatility spillovers across international energy and cereal commodity markets it also examines the impacts of three types of opec news announcements on the volatility spillovers and persistence in these markets for this purpose we make use of the var bekk garch and var dcc garch models for the daily spot prices of eight major commodities including wti oil europe brent oil gasoline heating oil barley corn sorghum and wheat our results provide evidence of significant linkages between these energy and cereal markets moreover the opec news announcements are found to exert influence on the oil markets as well as on the oil cereal relationships finally we show that the persistence of volatility decreases increases for the crude oil and heating oil gasoline returns after accounting for the opec announcements in these multivariate garch models however the results are more mixed for the cereal markets overall our results can be used to improve the risk adjusted performance by having more diversified portfolios and also serve to hedge the oil risk more effectively

comprehensive bidding strategies with genetic programming finite state automata this research is an extension of the authors previous work in double auctions aimed at developing bidding strategies for electric utilities which trade electricity competitively the improvements detailed in this paper come from using data structures which combine genetic programming and finite state automata termed gp automata the strategies developed by the method described here are adaptive reacting to inputs whereas the previously developed strategies were only suitable in the particular scenario for which they had been designed the strategies encoded in the gp automata are tested in an auction simulator the simulator pits them against other distribution companies distcos and generation companies gencos buying and selling power via double auctions implemented in regional commodity exchanges the gp automata are evolved with a genetic algorithm so that they possess certain characteristics in addition to designing successful bidding strategies whose usage would result in higher profits the resulting strategies can also be designed to imitate certain types of trading behaviors the resulting strategies can be implemented directly in online trading or can be used as realistic competitors in an off line trading simulator

an empirical study of an auction with asymmetric information this paper examines federal auctions for drain age leases on the outer continental shelf from 1959 to 1969 these are leases that are adjacent to tracts on which a deposit has been discovered the authors find that the data strongly support the hypotheses that neighbor firms are better informed about the value of a lease than nonneighbor firms that neighbor firms coordinate their bidding decisions and that both types of firms bid strategically in accordance with the bayesian nash equilibrium model for first price sealed bid auctions with asymmetric information

shared agents and competition in laboratory english auctions at livestock auctions the same purchasing agent can represent more than one processor repeated multiple unit english auctions are created in a laboratory to measure the impact of shared agents on trade prices under alternative treatments with six and as few as two agents representing six principals treatments are constructed in which the agents either know or do not know quantity for sale and in which there are progressively fewer agents bidding knowledge of quantity for sale can be anticompetitive evolution toward increased market concentration leads to consistent anticompetitive pricing resulting in prices significantly lower than the predicted competitive equilibrium prices

collusion in uniform price auctions experimental evidence and implications for treasury auctions in uniform price auctions of shares there exist collusive equilibria in which bidders capture the entire surplus from the auction as well as competitive equilibria in which the auctioneer captures the entire surplus from the auction we provide experimental evidence that in uniform price auctions non binding pre play communication facilitates convergence to collusive equilibrium outcomes on the other hand regardless of the opportunities for communication in discriminatory auction experiments subject strategies conform closely with the unique equilibrium in undominated strategies in which bidders gains are equal to the smallest tick size in the bidding schedule this evidence suggests that uniform price auctions of treasury securities may result in lower revenues than the currently employed discriminatory procedure

dynamics of oil price precious metal prices and exchange rate this study examines the co movements and information transmission among the spot prices of four precious metals gold silver platinum and palladium oil price and the us dollar euro exchange rate we find evidence of a weak long run equilibrium relationship but strong feedbacks in the short run the spot precious metal markets respond significantly but temporarily to a shock in any of the prices of the other metal prices and the exchange rate furthermore we discover some evidence of market overreactions in the palladium and platinum cases as well as in the exchange rate market in conclusion whether there are overreactions and re adjustments or not investors may diversify at least a portion of the risk away by investing in precious metals oil and the euro policy implications are provided

financial development and energy consumption in emerging markets smooth structural shifts and causal linkages abstract this study examines the dynamic interrelationships among financial development energy consumption and economic growth in emerging markets by focusing on accounting for structural changes in causal linkages we first employ the toda yamamoto causality framework and then augment it with a fourier approximation which captures structural shifts as a gradual smooth process the empirical findings show that taking into account gradual structural shifts matters for the causal linkages between financial development and energy consumption while the causality analysis which does not account for structural changes supports a causality between financial development and energy consumption only in 4 out of 21 emerging markets the causality analysis with structural changes provides a causal linkage in half of the sample this finding is consistent with the fact that emerging markets have experienced structural changes in either finance or energy sectors or both we also conduct additional analyses which point out that cross sectional dependency and the quantiles of the distribution matter for the causal linkages our results further shed light on the evidence that the economic activity mainly causes the financial development and energy consumption at the highest quantile of distribution in the fast growing emerging economies

resource compensation and negotiation support in an aboriginal context using community based multi attribute analysis to evaluate non market losses abstract compensation for losses of non market values experienced by aboriginal peoples due to adverse impacts on their land or resource base caused by others is an important issue for law and social justice yet the standard methods of economic valuation as a basis for determining compensation are not always suited to addressing the diverse values of aboriginal people this paper discusses an approach to valuation that employs concepts and methods of decision analysis informed by behavioral decision research in an applied context it uses a multi attribute value assessment as a basis for characterizing the relative significance of resource damages that affect deeply held complex intangible values we draw on the experience of conducting analyses for three metis settlements in alberta canada to illustrate the approach using a case study interpretations of the results as a basis for negotiation regarding compensation are examined

auctions with a buy price the case of reference dependent preferences abstract in an auction with a buy price the seller provides bidders with an option to end the auction early by accepting a transaction at a posted price this paper develops a model of an auction with a buy price in which bidders use the auction s reserve price and buy price to formulate a reference price the model both explains why a revenue maximizing seller would want to augment her auction with a buy price and demonstrates that the seller sets a higher reserve price when she can affect the bidders reference price through the auction s reserve price and buy price than when she can affect the bidders reference price through the auction s reserve price only the comparative statics properties of bidding behavior are in sharp contrast to equilibrium behavior in other models where the existence and size of the auction s buy price have no effect on bidding behavior

u s stock returns and oil prices the tale from daily data and the 2008 2009 financial crisis abstract using daily data from january 1999 to december 2011 we examine u s stock returns s p 500 dow jones nasdaq and russell 2000 based on a wide range of information including equity vix volatility inflation expectations interest rates gold prices and the usd euro exchange rate the focus is on oil price returns which have been previously found to exert mostly negative effects on u s stock returns identifying the crisis of 2008 2009 as a significant period of economic contraction and subsequent recovery we check the stability of the stock oil relationship by garch and mgarch dcc models prior to the financial crisis stock returns are slightly negatively affected by oil prices and by the usd euro for the subsample of mid 2009 onwards however stock returns are positively affected by oil prices and a weaker usd euro as with inflation expectations we interpret these findings as u s stocks responding positively to expectations of recovery worldwide our proposed explanation is due to the changing correlation between stock markets and oil either by standard garch models or by mgarch dcc models allowing the implied correlation to vary over time

oil prices and real estate investment trusts reits gradual shift causality and volatility transmission analysis abstract according to literature oil price shocks and volatility can have sector specific impacts in the market while these studies include most asset groups the dynamic relationship between the oil market and real estate investment trusts reits has not been tested this study examines the role of oil price shocks and volatility on six reit categories residential hotel healthcare retail mortgage and warehouse industrial reits for the january 2005 december 2013 period in addition a new causality approach is proposed by augmenting the toda yamamoto method with a fourier approximation this approach is capable of capturing gradual or smooth shifts and does not require a prior knowledge regarding the number dates and form of structural breaks the so called fourier toda yamamoto causality mean spillover test finds uni directional causality running from oil prices to all reits except for the mortgage reits in the latter case the causality is reversed in addition the relatively new and simple causality in variance test shows that there is bi directional volatility transmission between the oil market and all reits our results have important implications for reit managers and investors

oil prices and financial stress a volatility spillover analysis this paper examines whether there is a volatility transmission between oil prices and financial stress by means of the volatility spillover test we employ wti crude oil prices and cleveland financial stress index for the period 1991 2014 and divide the sample into pre crisis in crisis and post crisis periods due to the downward trend in oil price in 2008 the volatility model estimations indicate that oil prices and financial stress index are dominated by long run volatility the volatility spillover causality test supports evidence on risk transfer from oil prices to financial stress before the crisis and from financial stress to oil prices after the crisis the impulse response analysis shows that the volatility transmission pattern has similar dynamics before and after the crisis and is characterized by higher and long lived effects during the crisis our results have implications for both policy makers and investors and for future work

bringing stakeholder values into environmental policy choices a community based estuary case study this paper discusses a methodology for joining deliberation and analysis using the case study example of a national estuary program planning effort in tillamook bay or usa we describe the development of a community based evaluation tool that links actions proposed by technical experts e g biologists ecologists engineers to restore functioning of the tillamook bay estuary with the values and concerns expressed by community residents this task required the explicit consideration of trade offs across multiple benefits costs and risks we describe the design and results of an evaluation workbook developed with input from both the epa staff and community residents that provided insight to decision makers by presenting participants with explicit choices across the key dimensions and consequences of proposed actions the final section of the paper discusses the successes and limitations of the project in relation to evaluation needs associated with other environmental policy initiatives 2001 elsevier science b v all rights reserved

auctions with endogenous quantity this article studies auctions in which several sellers compete for the right to sell to a market characterized by a negatively sloped demand curve in this environment the quantity traded becomes endogenous this effect leads to three results concerning the outcomes of open versus first price sealed bid auctions first an open auction yields a higher expected price than does sealed bidding second and more important the open auction captures less of the potential gains from trade than does the sealed bid auction third for broad classes of demand curves the efficiency gains from switching to sealed bids from an open auction accrue to both sellers and the buyer so that all concerned parties would agree to the change a direct application of the theory is to procurement the heavy use of sealed bidding in procurement is seen as rational in light of these results auction models with endogenous quantity could be an alternative to price setting oligopoly models for the study of price formation in general for the latter impose strong information requirements on agents and yield only equilibrium price vectors not equilibrium processes for determining prices

the effectiveness of english auctions abstract we study the performance of the english auction under different assumptions about the seller s degree of bayesian sophistication we define the effectiveness of an auction as the ratio between the expected revenue it generates for the seller and the expected valuation of the object to the bidder with the highest valuation total surplus we identify tight lower bounds on the effectiveness of the english auction for general private values environments and for private values environments where bidders valuations are non negatively correlated for example when the seller faces 12 bidders who the seller believes have non negatively correlated valuations whose expectations are at least as high as 60 of the maximal possible valuation an english auction with no reserve price generates an expected price that is more than 80 of the value of the object to the bidder with the highest valuation

modeling and analysis of an auction based logistics market we consider a logistics spot market where the transportation orders from a number of firms are matched with two types of carriers through a reverse auction in the spot market local carriers compete with in transit carriers that have lower costs in order to analyze the effects of implementing a logistics spot market on these three parties firms local carriers and in transit carriers and also the effects of various system parameters we develop a two stage stochastic model we first model the auction in a static setting and determine the expected auction price based on the number of carriers engaging in the auction and their cost distributions we then develop a continuous time markov chain model to evaluate the performance of the system in a dynamic setting with random arrivals and possible abandonment of orders and carriers by combining these two models we evaluate the performance measures such as the expected auction price price paid to the carriers distribution of orders between local and in transit carriers and expected number of carriers and orders waiting at the logistics center in the long run we present analytical and computational results related to the performance of the system and discuss operation of such a logistics spot market in turkey

eliciting public values for complex policy decisions several approaches exist to illuminate and clarify public values relevant for making public policy decisions these include surveys indirect and direct value elicitation focus groups and public involvement this paper describes a new approach called the public value forum which combines elements of focus groups and direct multiattribute value elicitation techniques two public value forums were conducted with selected members of the west german public to elicit values relevant for setting long term energy policies the purposes of conducting the value forums were to examine the feasibility of eliciting values from laypeople and combining them with factual assessments of experts to determine the extent to which values elicited formally conflict with values elicited informally and to assess the advantages and disadvantages of the public value forum the results indicate that the public value forum is feasible that the participants felt comfortable with the procedure and that they were eager to resolve inconsistencies between their intuitive judgments and the multiattribute models there was substantial conflict between the formally and informally elicited values however the participants were able to resolve those conflicts in the course of the value forum tending towards more moderate alternatives in the process the public value forum provided useful information for the policy process and education for the participants however because it is expensive and time consuming its main application may involve small samples of opinion leaders and stakeholder representatives rather than large representative samples of the general public

a laboratory comparison of uniform and discriminative price auctions for reducing non point source pollution auctions allow regulators to identify land management changes with substantial environmental benefit and low opportunity cost this paper reports an experiment in which seller subjects compete in sealed offer auctions to obtain part of a fixed budget allocated by the experimenter regulator to subsidize pollution abatement one treatment employs uniform price auction rules whereas another treatment employs discriminative price auction rules we find that most offers in the uniform price auction are within 2 of cost whereas most offers in the discriminative price auction are at least 8 greater than cost nevertheless the discriminativeprice auction has superior overall market performance

sequential auctions with delay costs a two period model we examine the outcome of a two round second price auction of stochastically equivalent objects where players face delay costs if they decide to stay for the subsequent round in our model agents decide whether to stay for the next round after seeing their valuations for the good we describe an equilibrium involving a screening level such that only those bidders with values bigger than that amount decide to stay for the last period we also provide an example where expected prices are decreasing

auction design for the allocation of emission permits in the presence of market power to the extent that emission permits have been allocated using market mechanisms this has been done using a sealed bid auction design typically with discriminatory prices however several authors have recommended the ascending auction format basically two competing ascending auction designs have been suggested the standard ascending auction with clock or demand schedules or an alternative ascending clock implementation of vickrey pricing the latter design was introduced as a response to problems of bid shading under the sealed bid and the standard ascending auction format the purpose of this paper is to investigate the allocation of permits under these two alternative mechanisms the auction process and the resulting market outcome in the presence of oligopolistic competition are simulated in this setting it is not obvious that bid shading is the optimal strategy under the standard design nor is it obvious that sincere bidding is the optimal strategy under the alternative ascending auction design the alternative auction format makes it less costly to pursue a strategy to increase market shares through the acquisition of emission permits thus increasing the competitor s costs leading to overbidding as the optimal strategy

multi criteria auctions without full comparability of bids the emergence of auction mechanisms that support bids characterized by several attributes is one of the most recent evolutions within auction theory these mechanisms referred to as multi attribute multiple issue or multi dimensional auctions are at the intersection between multi criteria decision and auction theories the purpose of this paper is to introduce multi criteria auctions the originality of which is not to require full comparability between bids we claim that this distinctive feature is of great interest especially in procurement situations furthermore the existence of potential incomparability between multi dimensional offers will permit us to manage different bidding niches coexisting within the same bidding space a theoretical framework based on a general preference structure will be introduced and then referenced to existing approaches such as multi attribute auctions or new ones such as dominance based multi criteria auctions or butterfly auctions

price and volatility linkages between international reits and oil markets abstract this study analyzes price and volatility transmissions between nineteen real estate investment trusts reits and the oil markets the reits data represents a variety of countries at different stages of their development and the expanded analytical approach includes accounting for structural shifts as gradual processes as opposed to strictly abrupt processes typically assumed in the literature oil prices are found to primarily predict reits prices in mature reits markets but the feedback from reits to oil prices is weak from the perspective of volatility strong evidence of bidirectional transmission in majority of the markets is observed our results are in general robust to a shorter common sample period of the various countries this study further demonstrates the importance of accounting for gradual smooth structural shifts for price transmission analysis

the outsourcing of r d through acquisitions in the pharmaceutical industry abstract we examine the performance of 160 pharmaceutical acquisitions from 1994 to 2001 and find evidence that on average acquirers realize significant positive returns these returns are positively correlated with prior acquirer access to information about the research and development activities at target firms and a superior negotiating position a unique desperation index is employed to determine the current status of a firm s internal productivity we find that firms experiencing declines in internal productivity or which are more desperate are more likely to engage in an outsourcing type acquisition in an effort to replenish their research pipelines

the asymmetric effects of foreign direct investment on clean energy consumption in brics countries a recently introduced hidden cointegration test abstract this study investigates the effects of foreign direct investment and the trade openness on clean energy consumption for brics countries brazil russia india china and south africa during the period 1985 2017 for that purpose the study employs fourier adl autoregressive distributed lag and hidden fourier adl cointegration tests and fourier toda yamamoto approach to granger causality considering both raw data and the asymmetric components of the series empirical results reveal that these variables are cointegrated in russia china and south africa regarding hidden fourier adl cointegration test while they are cointegrated only in south africa considering the fourier adl test it is found that trade positively affects clean energy use in south africa in the context of negative components foreign direct investment has a positive impact on clean energy use in russia while its effect is insignificant in china and south africa moreover trade openness influences clean energy consumption negatively in russia china and south africa according to the fourier toda yamamoto and asymmetric fourier toda yamamoto causality tests results regarding negative components there is unidirectional causality from foreign direct investment inflows to clean energy consumption in china findings of this study may provide beneficial information to the policymakers to design proper environmental policies such as the imposition of the carbon tax and subsidy on cleaner energy consumption

the design of auctions and tenders with quality thresholds the symmetric case three designs of auctions with quality thresholds are considered the quality threshold is not known with certainty by the bidders in one scheme quality plans submitted by potential bidders are evaluated first and price bids for only those plans which have been approved are invited the second scheme has price bids first to yield a priority for scrutinising quality a third has simultaneous decisions on price and quality the model yields an equivalence result the use of reserve prices to produce social optimality is then investigated the theory is used to discuss the recent auction for uk television franchises

oil prices stock markets and portfolio investment evidence from sector analysis in europe over the last decade this article extends the understanding of oil stock market relationships over the last turbulent decade unlike previous empirical investigations which have largely focused on broad based market indices national and or regional indices we examine short term linkages in the aggregate as well as sector by sector levels in europe using different econometric techniques our main findings suggest that the reactions of stock returns to oil price changes differ greatly depending on the activity sector in the out of sample analysis we show that introducing oil asset into a diversified portfolio of stocks allows to significantly improve its risk return characteristics

auctions and bidding a primer maybe the contractor was right to think bid jobs are different but it is more likely that he suffered from too simple a view of what is involved in preparing a competitive bid our analysis will show that even an experienced estimator working in familiar terrain can lose money if he doesn t understand the subtleties of competitive bidding the phenomenon experienced by the painting contractor known as the winner s curse is just one of the surprising and puzzling conclusions that have been turned up by modern research into auctions another is the theoretical proposition supported also by some experimental evidence that for example a sealed bid treasury bill auction in which each buyer pays a price equal to the highest rejected bid would yield more revenue to the treasury than the current procedure in which the winning bidder pays the seemingly higher amount equal to his own bid there are also subtle results that demonstrate the equivalence of such apparently different institutions as the standard sealed bid auction in which the auctioneer seller sells the goods to the highest bidder for a price equal to his bid and the dutch auction in which the auctioneer seller begins by asking a high price and gradually lowers the price until

a profit based unit commitment ga for the competitive environment as the electrical industry restructures many of the traditional algorithms for controlling generating units need modification or replacement previously utilized to schedule generation units in a manner that minimizes costs while meeting all demand the unit commitment uc algorithm must be updated a uc algorithm that maximizes profit will play an essential role in developing successful bidding strategies for the competitive generator simply bidding to win contracts is insufficient bidding strategies must result in contracts that on average cover the total generation costs no longer guaranteed to be the only electricity supplier a generation company s share of the demand will be more difficult to predict than in the past removing the obligation to serve softens the demand constraint in this paper the authors provide a price profit based uc formulation which considers the softer demand constraint and allocates fixed and transitional costs to the scheduled hours the authors describe a genetic algorithm solution to this new uc problem and present results for an illustrative example

structuring west germany s energy objectives for this article a comprehensive and politically legitimate list of criteria to evaluate energy systems was constructed from interviews with leading representatives of a broad spectrum of west german society in the interviews we probed the fundamental values of nine political and social organizations including the catholic and lutheran churches the federation of german labour unions the association of german industries and the german nature society a hierarchical representation of value criteria was logically structured for each group separately and then aggregated into a combined value tree the result facilitates communication and constructive compromise promotes the creation of policy options and helps evaluate future energy systems

efficient estimation methods for closed ended contingent valuation surveys closed ended contingent valuation surveys can be very useful in the evaluation of nonmarket resources respondents merely state whether they would accept or reject a hypothetical threshold amount either as payment for giving up access to the resource or as a fee for its use the authors develop a maximum likelihood procedure which exploits the variation in the threshold values to allow direct and separate point estimates of regression like slope coefficients and error standard deviations without truncation bias their illustration uses data from a survey of recreational fisherman to examine factors which influence individuals willingness to pay copyright 1987 by mit press

volatility spillover between oil and agricultural commodity markets abstract this study examines volatility transmission between oil and selected agricultural commodity prices wheat corn soybeans and sugar we apply the newly developed causality in variance test and impulse response functions to daily data from 01 january 1986 to 21 march 2011 in order to identify the impact of the food price crisis the data are divided into two sub periods the pre crisis period 01 january 1986 to 31 december 2005 and the post crisis period 01 january 2006 21 march 2011 the variance causality test shows that while there is no risk transmission between oil and agricultural commodity markets in the pre crisis period oil market volatility spills on the agricultural markets with the exception of sugar in the post crisis period the impulse response analysis also indicates that a shock to oil price volatility is transmitted to agricultural markets only in the post crisis period this paper thereby shows that the dynamics of volatility transmission changes significantly following the food price crisis after the crisis risk transmission emerges as another dimension of the dynamic interrelationships between energy and agricultural markets

a theory of value with non linear prices equilibrium analysis beyond vector lattices this paper presents a new theory of value with a personalized pricing system that naturally induces a family of non linear prices this affords a coordinate free theory of value in which the analysis is without any lattice theoretic considerations when commodity bundles are perfectly decomposable the generalized prices become linear and the analysis specializes to the walrasian model this happens for instance whenever the commodity space is a vector lattice and consumption sets coincide with the positive cone our approach affords theorems on the existence of equilibrium and provides a value based characterization of pareto optimality and edgeworth equilibrium where the walrasian linear price based characterization fails the analysis has applications in the finite as well as the infinite dimensional setting journal of economic literature classification numbers c62 c71 d46 d51 d61

discriminatory versus uniform treasury auctions evidence from when issued transactions abstract we use when issued transactions data to assess the treasury s current experiment with uniform auctions when issued volume is higher under uniform as compared to discriminatory auctions suggesting a higher information release which should reduce pre auction uncertainty and the winner s curse under uniform auctions when issued volatility falls after the auction and again after the outcome announcement the pattern is the opposite for discriminatory auctions this is further evidence that uniform auctions increase pre auction information and lower the short squeeze a direct comparison of markups in uniform and discriminatory auctions yields mixed results

regulatory measurement and evaluation of telephone service quality regulators of utilities that operate as local monopolies would like to set prices or allow rates of return based upon the quality of a utility s service however quality is highly multidimensional traditionally regulators have collected measures of quality on many separate dimensions and compared performance on these dimensions to explicit pass fail standards they have lacked a method of combining complex patterns of substandard and superstandard performance on these many dimensions to arrive at an overall evaluation of the quality of service to redress this problem we first describe the information processing problems regulators encounter when they attempt to integrate this complex array of information intuitively and the problems that arise when the link between service quality as reflected in patterns of passed and failed standards and regulatory incentives is not made explicit to utility management we develop a bootstrapped method for formalizing each expert regulator s evaluation policy us

testing the ekc hypothesis for the top six hydropower energy consuming countries evidence from fourier bootstrap ardl procedure abstract environmental degradation is an important threat to sustainable development economic growth and fossil fuel based energy consumption are main factors causing environmental pollution the use of renewable energy as an alternative for fossil fuels can help to reduce environmental pollution and thus sustainable development can be achieved from this point of view hydropower is the most widely used renewable energy source in several countries however the effects of hydropower energy on the environment are controversial to add a new dimension to the discussion this study investigates the relationship between hydropower energy consumption ecological footprint and economic growth for the top six hydropower consuming countries within the framework of the environmental kuznets curve ekc hypothesis the study employs newly developed cointegration and causality tests with smooth structural changes over the period 1965 2016 the findings of the fourier bootstrap ardl procedure demonstrate that no cointegration exist between the variables therefore the ekc hypothesis is not valid for brazil china canada india norway and the us furthermore the findings of the fourier toda yamamoto causality test suggest unidirectional causality running from hydropower energy consumption to economic growth in brazil and bidirectional causality between these variables in china in the case of the top six hydropower consuming countries no evidence was found for a causal relationship between hydropower energy and ecological footprint overall these results are important for policy makers hydropower energy plays a crucial role in china and brazil s economic growth policies on the other hand hydropower energy consumption and economic growth do not have a role in mitigating the ecological footprint in six countries for this reason different types of renewable energy consumption should be taken into consideration by countries for the solution of environmental problems

valuing environmental policy options a case study comparison of multiattribute and contingent valuation survey methods this paper describes a promising new evaluation approach called a value integration survey that uses the objectives and tradeoffs expressed by participants to value environmental policy options this constructive technique which builds on the interactive elicitation process of decision analysts assists stakeholders in clarifying their values and in agreeing on a policy alternative the paper compares this multi attribute valuation method to contingent valuation surveys describes the sequence of respondents tasks and presents results from a case study comparison of contingent valuation and value integration survey methods in the context of valuing options for fire control in oregon s oldgrowth forests

bid dispersion competition and wage regulation some field evidence from public contract bidding in british columbia the paper uses data from british columbia to show that bid dispersion the difference between the winning and next lowest bids in public school construction contract bidding is very compact and that it varies inversely with the degree of competition it also examines the impact of the skill development and fair wage law sdfwp which promulgated wage scales and required contractors to pay them in public construction projects on the bid dispersion multivariate analysis shows that bid dispersion declined after sdfwp one possible interpretation of this result is that the contractors became less prone to the winner s curse following the sdfwp

markup pricing in mergers and acquisitions this paper studies the relation between the premiums in takeover bids involving exchange listed target firms from 1975 91 and the pre announcement stock price runups the evidence shows that the pre bid runup and the postannouncement increase in the target s stock price the markup are generally uncorrelated with little substitution between the runup and the markup the runup is an added cost to the bidder this finding has important implications for assessing the costs of insider trading it also raises interesting questions about the role of information from public capital markets in private takeover negotiations

oil price movements and stock markets revisited a case of sector stock price indexes in the g 7 countries abstract applying sector stock prices and oil prices in 1991 01 2009 05 from the g7 countries we find oil price shocks do not significantly impact the composite index in each country however stock price changes in germany the uk and the us were found to lead oil price changes as for the interaction between oil price changes and sector stock price changes we find short run negative causal relationships 4 of 7 sector index returns were impacted by oil price changes in germany 2 in the us and 1 in france in particular stock returns of information technology and consumer staples sectors were found to be impacted most by oil price shocks followed by financial utilities and transportation sectors in terms of causality from sector stock price changes to oil price changes we find stock price changes lead oil price changes in 8 of 9 sectors in germany most in the g7 countries followed by the uk italy france canada and the us no such a causal relationship however is found for japan with respect to specific sectors stock price changes in consumer staples and materials sectors were impacted most significantly by oil price changes followed by transportation financial energy health care industrials utilities information technology and telecommunication sectors with the exception of consumer discretionary sector in addition short term stock price changes are found to lead positively oil price changes

information returns and bidding behavior in ocs auctions 1954 1969 this paper examines federal auctions for leases on the outer continental shelf in the light of the predictions of the first price sealed bid common values model of auctions the authors find that the data strongly support the model for auctions in which one bidder is better informed than the other bidders the evidence for auctions in which bidders have noisy but qualitatively similar information is less conclusive but is consistent with a model in which each bidder does not know either the actual or potential number of bidders on a lease copyright 1987 by blackwell publishing ltd

child auctions in nineteenth century sweden an analysis of price differences during the nineteenth century destitute and or orphan swedish children were boarded out as a part of that time s public assistance the families to which they were allocated were determined by means of english auctions this paper studies the price differences among such children using empirical data from 601 auctions price is regressed on variables related both to the buyer and to the child the results suggest that variables related to the children s characteristics were important and that the willingness to take a poor or orphan child was dependent on the foster parents uses for a child in the household children who were old enough to be used as shepherd boys or girls were easily placed it was worse with those who were feeble incapacitated blind sick mentally deranged or confined to their beds they were useless to farmers and others as a rule the most miserable were boarded out to the poorest of the non property owners julius ejdestam 1969 the poor s sweden my translation
