optimal replication of contingent claims under portfolio constraints we determine the minimum cost of superreplicating a nonnegative contingent claim when there are convex constraints on portfolio weights we show that the optimal cost with constraints is equal to the price of a related claim without constraints the related claim is a dominating claim that is a claim whose payoffs are increased in an appropriate way relative to the original claim the results hold for a variety of options including some path dependent options constraints on the gamma of the replicating portfolio constraints on portfolio amounts and constraints on the number of shares are also considered article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

measuring corporate sustainability management a data envelopment analysis approach despite the increased awareness of the conceptual and practical definition of corporate sustainability questions remain on how to measure performance the objective of this paper is to advance our understanding of the measurement of corporate sustainability management by introducing a data envelopment analysis dea technique and an empirical case of a korean electronics industry in particular we employ cross efficiency in the presence of dual role factors by reflecting some complexity of a real world case donations for tax benefits by employing the combined approach of cross efficiency and dual role factors we offer a new model to measure corporate sustainability management the new model and study findings contribute to the body of knowledge in corporate sustainability management and its performance measurement

energy efficiency in the transport sector in the eu 27 a dynamic dematerialization analysis abstract energy use in the european union s eu transport sector amounted to 340 mtoe 1 in 1999 with the following increasing trend up to 379 mtoe in 2007 and a decrease from 2008 on down to 365 mtoe in 2010 this changing pattern posed several fundamental questions and uncertainties regarding the broader picture of energy efficiency and environmental protection one of them refers to absolute changes in energy use efficiency in the transport sector over time and the ways of measuring efficiency traditional scientific approaches conceptualized to measure efficiency of energy use do not address annual dynamics of changes in the energy use in a given sector per capita thus they are not precise enough for political and methodological purposes as they do not reflect the exact amount of energy consumed in the respective countries and societies this paper shows a possible solution to this problem and a new perspective on measuring energy efficiency by using the product generational dematerialization pgd indicator the pgd indicator allows for measuring energy efficiency as a dynamic change of consumption and population occurring simultaneously thus it provides an extension to the traditional methodology commonly used for measuring efficiency to visualize a practical application of this approach the paper provides an example of evaluating energy efficiency in the transport sector in the eu 27 in 2000 2010 the results of the analysis show a clear materialization tendency in the transport sector the energy consumption change exceeded the population growth until 2007 and a reverse tendency dematerialization between 2008 and 2010 as energy consumption has a direct impact on environmental quality and exhaustion of natural resources the paper points out the necessity of extending sustainable resource management policies by new methodologies and providing more efficient solutions for energy consumption in the transport sector

assessing the sustainability performances of industries business sustainability entails the incorporation of the objectives of sustainable development namely social equity economic efficiency and environmental performance into a company s operational practices companies that compete globally are increasingly required to commit to and report on the overall sustainability performances of operational initiatives the current indicator frameworks that are available to measure overall business sustainability do not effectively address all aspects of sustainability at operational level especially in developing countries such as south africa social criteria specifically do not receive due considerations this article proposes a new framework to assess the sustainability of operations in the manufacturing sector

asymmetric private values auctions with application to joint bidding and mergers abstract much of the theoretical auction literature assumes that there are no observable differences between the bidders of an auction in this paper i present an asymmetric auction model where the distribution of a bidder s value depends on some commonly observed characteristics the model is applied to joint bidding and mergers in auction markets the results provide additional evidence that first price auctions are less susceptible to the acquisition and exercise of market power than open auctions

option listing and stock returns abstract this article examines the effect of option introductions on the underlying stocks in addition to the price increase and volatility decrease that take place when new options are listed we obtain and explain the following new empirical results i an increase in the value of the market around the listing dates of new options ii an increase in the value of an industry index which excludes the optioned stocks iii the dissipation of the price and volatility effects in recent periods and iv the existence of an announcement effect in one subperiod of our sample and its dissipation in recent periods

foreign direct investment as a way to guide the innovative process towards sustainability abstract in 1972 for the first time the term sustainable development was coined at the stockholm conference and in 1987 the brundtland report established the sustainability innovation binomial since then extensive research into sustainability oriented innovation has been conducted focused during the last decade on smes and recognizing these as the main actor of sustainable development for which foreign direct investment fdi is considered from a research and institutional point of view as a vital source although academic literature presents conflicting conclusions in this context this paper aims to perform a microeconomic analysis of how fdi influences the innovative process of smes and how this can lead to a process oriented towards sustainability to this end a panel of 4667 smes has been analyzed spanning a sample period between 2004 and 2013 through a binary logit model which compares and contrasts smes with fdi and equivalent smes without fdi over time and therefore exposed to a changing economy the most significant results are that fdi is attracted mainly by factors associated with technological supply which when coupled with being of medium size and located in a manufacturing sector of medium high technology generates positive spillovers these depend to a large extent on public funding which allows these companies to be more innovative and makes it more likely they focus their innovative process on sustainability

leverage constraints and the optimal hedging of stock and bond options this paper considers the problem of a financial institution that needs to hedge a stream of state contingent cash flows while facing borrowing and short sales restrictions the study determines analytically the strategy that minimizes the initial cost of hedging the desired cash flow which is also the upper bound on its market price and shows that the impact of leverage constraints on the cost of hedging call and put options is significant and therefore the biases detected by tests of option pricing models may not represent arbitrage opportunities the paper also shows that with credit limits it is optimal to reduce the rate of trading thus these constraints need to be recognized when estimating the trading volume generated in replicating contingent payoffs such as portfolio insurance

linear and non linear price decentralization compendious and thorough solutions to the existence of a linear price equilibrium problem the second welfare theorem and the limit theorem on the core are provided for exchange economies whose consumption sets are the positive cone of arbitrary ordered frechet spaces dispensing entirely with the assumption that the vector ordering of the commodity space is a lattice the motivation comes from economic applications showing the need to bring within the scope of equilibrium theory vector orderings that are not lattices which arise in the typical model of portfolio trading with missing options the assumptions are on the primitives of the model they are bounds on the marginals of non linear prices and for proper economies they are both sufficient and necessary

can affirmative action be cost effective an experimental examination of price preference auctions one of the most controversial questions facing our economy and society in recent years is the question of affirmative action the debate centers around an issue of minority representation in which the rights of the majority are depicted as being compromised by affirmative action programs set up to increase the welfare of minorities implicit in this discussion is the assumption that all affirmative action programs must be cost increasing this result it is claimed follows trivially from economic theory since any interference into the competitive process which prevents the most capable from being chosen must be wasteful and costly in this paper we challenge this claim with experimental results demonstrating that pricepreference auctions in which high cost minority firms are given preferential treatment in the awarding of contracts in such a way that it is possible for these firms to win a contract but not have submitted the lowest bid can be programs that both enhance minority representation and are cost effective in that they decrease the cost of government procurement in the theoretical literature on asymmetric auctions eric maskin and john riley 1995 and the optimal auction literature roger myerson 1981 it has been shown that in asymmetric auctions in which firms draw their costs from

why do sellers usually prefer auctions we compare the most common methods for selling a company or other asset when participation is costly a simple simultaneous auction and a sequential process in which potential buyers decide in turn whether to enter the bidding the sequential process is always more efficient but preemptive bids transfer surplus from the seller to buyers because the auction is more conducive to entry precisely because of its inefficiency it usually generates higher expected revenue we also discuss the effects of lock ups matching rights break up fees as in takeover battles entry subsidies etc

is subsidizing inefficient bidders actually costly a widespread practice particularly in public sector procurement and dispersal is to subsidize a class of competitors believed to be at an economic disadvantage arguments for such policies vary but they typically assume that benefits of subsidization must be large enough to outweigh a presumed economic cost of the subsidy when disadvantaged competitors compete in auctions the subsidy serves to make them more competitive rivals other bidders rationally respond by bidding more aggressively we consider a model of procurement auctions and show that a policy of subsidizing inefficient competitors can lower expected project cost and also enhance economic efficiency some subsidy is generally better than no subsidy for a wide range of parameters

spanning and completeness with options the role of ordinary options infacilitating the completion of securities markets is examined in the context of a model of contingent claims sufficiently general to accommodate the continuous distributions of asset pricing theory and option pricing theory in this context it is shown that call options written on a single security approximately span all contingent claims written on this security and that call options written on portfolios of call options on individual primitive securities approximately span all contingent claims that can be written on these primitive securities in the case of simple options explicit formulas are given for the approximating options and porfolios of options these results are applied to the pricing of contingent claims by arbitrage and to irrelevance propositions in corporate finance

alternative common value auction procedures revenue comparisons with free entry the logic of revenue comparisons for different types of common value auctions is substantially altered if the number of participants rather than being fixed responds endogenously to the expected profitability from participating in a thoroughly symmetric model a seller may prefer that competition be indirect an auction procedure in which fewer participants are needed to drive the expected profitability from participating down to the level obtainable in other auctions in the economy can attain higher expected revenue if a sale is sufficiently likely this insight allows a complete revenue ranking of standard auction procedures with endogenous entry

optimal auctions with financially constrained buyers abstract we study the sale of an indivisible good to liquidity constrained buyers they cannot pay more than their budget regardless of their valuation both valuation and budget are private information we derive the symmetric revenue maximizing and constrained efficient auctions in this setting we show an implementation via a modified all pay auction the highest bidder need not win the good outright or stated differently the auction has pooling despite the usual regularity conditions subsidizing low budget buyers cannot increase revenue from a technical standpoint we contribute to auction design with multidimensional private information by working directly with reduced form allocation rules

numerical analysis of asymmetric first price auctions abstract we propose numerical algorithms for solving first price auction problems where bidders draw independent valuations from heterogeneous distributions the heterogeneity analyzed in this work is what might naturally emerge when subsets of distributionally homogeneous bidders collude bid functions and expected revenues are calculated for two special cases extensions to more general asymmetric first price auctions are discussed journal of economic literature classification numbers d44 c63 c72 d82

options sunspots and the creation of uncertainty we present two examples in which the addition of an option market leads to sunspot equilibria despite the fact that no sunspot equilibria exist without the market these examples highlight limitations in two prevalent views of option markets it is often assumed that option markets help complete otherwise incomplete markets we demonstrate that they can instead increase the number of events agents wish to insure against as in black and scholes it is often assumed that option markets are redundant we demonstrate that an option market may not be redundant even when markets were complete before its introduction

portfolio selection with a drawdown constraint abstract when identifying optimal portfolios practitioners often impose a drawdown constraint this constraint is even explicit in some money management contracts such as the one recently involving merrill lynch management of unilever s pension fund in this setting we provide a characterization of optimal portfolios using mean variance analysis in the absence of a benchmark we find that while the constraint typically decreases the optimal portfolio s standard deviation the constrained optimal portfolio can be notably mean variance inefficient in the presence of a benchmark such as in the merrill lynch unilever contract we find that the constraint increases the optimal portfolio s standard deviation and tracking error volatility thus the constraint negatively affects a portfolio manager s ability to track a benchmark

bankruptcy limited liability and the modigliani miller theorem this paper examines the validity of the modigliani miller theorem in the presence of bankruptcy the theorem asserts that the value of a firm and the set of return patterns that the capital markets offer to private investors are independent of firm debt equity ratios the usual proof of the theorem is based on the presumption that in perfect capital markets borrowing by firms and borrowing by individuals can be perfect substitutes it is unclear whether this presumption is valid when there is a positive probability that either the firm or the individual who borrows to invest in the firm goes bankrupt on the one hand joseph stiglitz 1969 and robert merton have argued that the modigliani miller theorem remains valid even with bankruptcy if agents who borrow to invest in a firm can limit their liability to the amount of collateral they put up on the other hand vernon smith 1972 has argued that a margin loan which is secured by a pure equity collateral has a different return pattern from a direct loan to the firm and cannot serve as a substitute for the latter see also david baron smith s argument raises a number of issues first it brings out the important fact that return patterns for limited liability borrowing and lending depend on the composition of the portfolio that serves as collateral if a firm goes bankrupt a pure equity collateral is worthless whereas a collateral that contains some bonds may still earn a positive return because the bonds have a privileged claim to the firm s remaining assets in general margin contracts with different collateral compositions will generate different return patterns both for the borrower and the lender given this multiplicity of return patterns on margin loans one would not expect that all margin loans can be used as substitutes for direct loans to the firm this intuition is confirmed by smith s demonstration that a particular margin loan namely the loan on pure equity collateral cannot serve this purpose the question remains open whether this is actually needed for the modiglianimiller theorem it might be enough if some appropriate margin loan could be used as a substitute for lending to the firm in pursuing this problem one finds a gap in the standard proof of the modiglianimiller theorem usually one applies an arbitrage argument to show that as a firm changes its debt equity ratio investors in shares and bonds adjust their portfolios so as to leave their overall return patterns unchanged no such arguments are given for other securities related to the firm in particular for margin investments and for margin loans that serve to finance those margin investments without an analysis of professor of economics university of bonn research on this paper was supported by nsf grant soc 75 13437 at princeton university and by the deutsche forschungsgemeinschaft i have benefited from the advice of dwight jaffee and an anonymous referee in a similar vein stiglitz 1972 asserts the value of the firm decregses because there is a divergence in the estimation of the chances of bankruptcy between the lender and the borrower p 467 this analysis rests upon a form of market segmentation that is without economic merit in his model there are two groups of agents optimists and pessimists the optimists invest all their wealth in the firm s equity valued to make the rate of return equal to that on the riskless asset the pessimists are indifferent between the risky firm s bonds and the riskless asset it follows that the optimists being more optimistic than the pessimists must prefer the risky bond to the riskless asset and hence to the equity yet stiglitz assumes that the optimists invest in the equity and not in the risky bond of course if one group invests all its wealth into one asset that asset need not satisfy a marginal equality condition at all a correct analysis of his model leads to the results of this paper

evaluating environmental performance using data envelopment analysis the case of european countries abstract environmental efficiency is considered to be a critical pillar of sustainable development consequently improving environmental performance has aroused attention at both the local and global level this study evaluated the environmental performance of european union eu countries using the data envelopment analysis dea approach and the global malmquist luenberger index although literature using the dea approach to measure environmental performance exists this study s main contribution was considering different types of undesirable outputs and using long term panel data on eu countries in particular the dea window analysis technique was applied to evaluate the environmental performance of 27 eu countries in cross sectional and time varying data during the period 2000 2017 three dea models were examined labor capital and energy were used as common inputs with a combination of different outputs including gross domestic product carbon dioxide and particulate matter emissions and waste the empirical results revealed that the trends in the environmental performance of the entire eu and its individual countries were similar under all examined models environmental performance was indeed negatively affected by the financial crisis of 2007 2008 this impact was mainly observed in eastern eu countries furthermore both economic and environmental variables significantly influenced countries overall efficiency the analysis using the global malmquist luenberger index elucidated that overall eu countries experienced the efficiency improvement during the study period although fluctuations were observed these results enable countries and policymakers to understand their environmental performance identify strengths and weaknesses and set targets for further improvement based on the current best practices of comparable peers

government procurement and international trade abstract we model the bidding for a government contract in which there is imperfect competition each bidder is better informed about his own costs than either his rival bidders or the government and the distribution of the domestic firms costs differs from the distribution of foreign firms costs because of comparative advantage effects we find that the government minimizes its expected procurement cost by operating a price preference policy not necessarily purchasing from the lowest bidder

equilibrium in sealed high bid auctions there is a voluminous theoretical literature on sealed high bid auctions auctions in which bids are sealed and the high bidder pays his bid see for example vickrey 1961 myerson 1981 riley and samuelson 1981 milgrom and weber 1982 matthews 1983 maskin and riley 1984 holt 1980 cox smith and walker 1988 a critical property on which this literature relies is the existence of equilibrium in which buyers bidding strategies are monotonic in their types this enables the analyst to perform comparative statics as the distribution of types changes and to compare the welfare properties of the high bid auction with those of other auction institutions one case in which the existence of monotonic equilibrium is readily established is that in which buyers types are distributed smoothly independently and symmetrically in this case there exists a symmetric equilibrium one in which all bidders share the same bidding behaviour as a function of their valuations and this bid function is the solution to a first order differential equation

strategic perspectives of corporate sustainability management to develop a sustainable organization sustainable development refers to an economic environmental and social development that meets the needs of the present and does not prevent future generations from fulfilling their needs in this context businesses play an important role however progress towards sustainable development has been slow indicating the need for more concrete guidance that will allow businesses to act strategically and successfully in a sustainable way this theoretical paper connects three distinct but complementary dimensions of strategic management as viewed from the perspective of sustainability in order to encourage the integration of sustainability issues into corporate activities and strategies these three dimensions are strategy process strategy content and strategy context sixteen propositions related to these dimensions have been developed to explore the contributions of corporate sustainability management to the creation of value for businesses society and nature this theoretical discussion contributes to existing research in that it reveals relationships between strategic management and sustainable development and provides an agenda for further empirical research

social sustainability assessments in the biobased economy towards a systemic approach abstract the majority of impact assessments for the biobased economy are primarily focused on the environmental and techno economic aspects while social aspects are rarely considered this study proposes a modified systemic approach for a social sustainability impact assessment of the biobased economy based on a review on the common methodologies for assessing social impacts accordingly the proposed approach follows the four general iterative steps of social life cycle analysis slca as it considers all life cycle phases of the biobased economy the systemic approach considers the potential social impacts on local communities workers and consumers as the main three groups of the stakeholders the review showed that the most common social indicators for inventory analysis within the biobased economy include health and safety food security income employment land and worker related concerns energy security profitability and gender issues multi criteria decision analysis mcda was also highlighted as the broadly utilized methodology for aggregating the results of impact assessments within the biobased economy taking a life cycle perspective this study provides a holistic view of the full sustainability of research design and innovation in the biobased economy by suggesting the integration of the social aspects with techno economic and an environmental life cycle assessment our proposed systemic approach makes possible to integrate the social impacts that are highly valued by the affected stakeholders into the existing sustainability models that focus only on environmental and techno economic aspects we discuss the steps of the proposed systemic approach in order to identify the challenges of applying them within the biobased economy these challenges refer mainly to the definition of the functional unit and system boundaries the selection and the analysis of social indicators inventory analysis the aggregation of the inventory to impact categories and the uncertainties associated with the social sustainability evaluation the result of this review and the proposed systemic approach serve as a foundation for industry and policy makers to gain a better insight into the importance of social sustainability impacts assessment within the biobased economy

what does corporate strong sustainability actually mean in the real market world a response to bjorn and ropke abstract in a recent issue of the journal of cleaner production bjorn and ropke 2018 publish an article titled what does it really mean to be a strongly sustainable company a response to nikolaou and tsalis through which they express their concerns over the methodological framework developed by nikolaou and tsalis 2018 bjorn and ropke point out some weaknesses of this methodology suggesting some possible amendments to improve it specifically they raise doubts over the selection of environmental indicators and the definition of thresholds taking into consideration the points discussed by bjorn and ropke this paper aims to analyze the relevant theoretical background on which our framework was built by clarifying the concepts of corporate strong sustainability it also underlines some misconceptions of bjorn and ropke in relation to our framework and their proposed approach as well as making some suggestions for a possible new framework for corporate strong sustainability business oriented approach which encompasses the united nation un 2030 agenda for sustainable development and the corporate strong sustainability principles

markets that don t replicate any option abstract it is well known from the work of s ross that a securities market is complete if and only if each call option can be replicated using available securities the present short note announces the following surprising complementary result to ross important contribution if the number of securities is less than half the number of states of the world then generically not a single option can be replicated by traded securities this provides further strong motivation for relaxing the assumption of a perfect market in the theory of option pricing and portfolio insurance

endogenous asymmetry in a dynamic procurement auction we show how to numerically solve for a markov perfect equilibrium of a dynamic auction game where a procurer repeatedly purchases construction services from capacity constrained firms we find that the procurer is best off scheduling frequent auctions for small project sizes otherwise firm capacity utilization rates become larger and more asymmetric which softens competition and increases procurement costs we also find that forward looking bidding dampens the competition softening effects of asymmetry farsighted firms compete more intensely than myopic ones this can undermine the goal of a bid preference style affirmative action program more farsighted firms respond less to the asymmetry induced via bid preferences

short term market risks implied by weekly options we study short maturity weekly s p 500 index options which provide a direct way to analyze volatility and jump risks unlike longer dated options they are largely insensitive to the risk of intertemporal shifts in the economic environment adopting a novel seminonparametric approach we uncover variation in the negative jump tail risk which is not spanned by market volatility and helps predict future equity returns as such our approach allows for easy identification of periods of heightened concerns about negative tail events that are not always signaled by the level of market volatility and elude standard asset pricing models

spanning with index options current literature stresses that efficient funds do not exist when asset returns are contin uously distributed this paper shows that the existence of efficient funds can be restored if security returns are generated by a linear factor model

withdrawable bids as winner s curse insurance when bidders have a common value or strongly affiliated values for an object or contract being auctioned by sealed bids it is possible that the maker of a rational and apparently winning bid would upon learning the competing bids prefer losing the auction to honoring his bid the ability to withdraw a bid perhaps at a cost in such circumstances provides a form of winner s curse insurance bidding with such insurance is analyzed obtaining the general condition for rational bid withdrawal and sufficient conditions for the existence of an equilibrium with more aggressive bidding next we define a compensation penalties bid withdrawal penalty scheme and show that with it the bid taker is better off on the average than if bid withdrawal is impossible finally we find equilibrium bidding and withdrawal strategies in a multiplicative model as a function of the magnitude of the bid withdrawal penalty and of the bid taker s likelihood after a withdrawal of honoring the second best bid this model has

asymmetry in procurement auctions evidence from snow removal contracts differences in cost efficiency and productivity across firms may introduce asymmetries in procure ment auctions relying on a structural approach this article investigates potential asymmetry among firms bidding for snow removal contracts in montrthe empirical results show that firms located in close proximity have a cost advantage relative to other firms in the most urbanised part of montrbecause of prohibitive equipment storage costs the extent of inefficiency due to asym metry is empirically assessed various policy experiments are performed a bidding preference policy shows that the city could expect to reduce its costs for allocating snow removal contracts when bidders willingness to pay depends in part on observable variables the princi pal s interest is not best served by creating a level auction playing field this article studies procurement auctions for snow removal contracts in montrit investigates the degree to which companies in disadvantageous locations should win even if they do not submit the lowest bid from the submitted bids a novel empirical methodology estimates the extent of cost variation across firms along with its variation within loca tion although the dispersion is substantial the gain from treating bidders unequally is limited when observed individual characteristics affect the firms costs and their bidding strategies all bidders cannot be treated alike these differences in characteristics or asymmetries among bidders may arise from their size as noted by laffont et al 1995 their capacity constraints as in jofre bonet and pesendorfer 2003 or the possession of better information as in hendricks and porter 1988 and hendricks et al 1994

efficient funds in a financial market with options a new irrelevance proposition under the same assumptions that ross used to assert the existence of an efficient fund on which a spanning set of options can be written we prove that almost any portfolio is an efficient fund from a constructive point of view a randomly chosen vector of portfolio weights yields an efficient fund when the ross assumptions are relaxed a limited notion of efficiency maximal efficiency is the best attainable the maximally efficient funds are also everywhere dense in the portfolio space some implications are discussed and illustrative examples given the theory of consumer and firm behavior in economies with a complete set of contingent claims is rather well understood these complete market structures1 bring about competitive equilibria where consumers maximize utility firms maximize profits and prices adjust to match demand and supply as shown in debreu 7 all competitive equilibria are pareto optimal and any pareto optimum can be sustained as a competitive equilibrium it is commonly recognized however that complete markets have not come into

equilibrium open interest abstract this paper analyses what determines an individual investor s risk sharing demand for options and aggregating across investors what the equilibrium demand for options we find that agents trade options to achieve their desired skewness specifically we find that portfolio holdings boil down to a three fund separation theorem that includes a so called skewness portfolio that agents like to attain our analysis indicates also however that the common risk sharing setup used for option demand and pricing is incompatible with a stylized fact about open interest across strikes

in house competition organizational slack and the business cycle multiplant firms pit their facilities against each other for production assignments the present paper studies the consequences of this practice in a model where production is limited by capacity constraints and asymmetric information allows facilities to accumulate slack it shows the amount of slack per unit of output to be pro cyclical indeed as capacity constraints become more acute in economic booms the power of in house competition for quota assignments is reduced and slack per unit of output increases while the opposite is true in downturns moreover in downturns firms may use higher cost facilities even when lower cost plants are not running at capacity since this boosts x efficiency in low cost plants

premium auctions and risk preferences abstract in a premium auction the seller offers some payback called premium to a set of high bidders at the end of the auction this paper investigates how the performance of such premium tactics is related to the bidders risk preferences we analyze a two stage english premium auction model with symmetric interdependent values in which the bidders may be risk averse or risk preferring upon establishing the existence and uniqueness of a symmetric equilibrium we show that the premium causes the expected revenue to increase in the bidders risk tolerance a net premium effect is key to this result

optimal replication of options with transactions costs and trading restrictions this paper analyzes the strategy that minimizes the initial cost of replicating a contingent claim in a market with transactions costs and trading constraints the linear programming and two stage backward recursive models developed are applicable to the replication of convex as well as nonconvex payoffs and to a portfolio of options with different maturities the paper s formulation conveniently accounts for fixed and variable transactions costs lot size constraints and position limits on trading the article shows that in the presence of trading frictions it is no longer optimal to revise one s portfolio in each period at the optimum cash flows in excess of the desired ones may be generated the optimal policy trades off the curvature of the payoff that is generated against the terminal slack

spanning and completeness in markets with contingent claims abstract we characterize financial markets that are complete or that contain portfolios which span all measurable functions of a particular asset payoffs either finite and infinite dimensional these results are then employed to describe the extent to which options trading is sufficient to complete markets to investigate the existence of efficient funds and to establish the extent of market completeness required to ensure the unanimity and irrelevance results of modern corporation finance

first price auctions in the asymmetric n bidder case i consider the first price auction when the bidders valuations may be differently distributed i show that every bayesian equilibrium is an essentially pure equilibrium formed by bid functions whose inverses are solutions of a system of differential equations with boundary conditions i then prove the existence of an equilibrium i prove its uniqueness when the valuation distributions have a mass point at the lower extremity of the support i give sufficient conditions for uniqueness when every valuation distribution is one of two atomless distributions i establish inequalities between equilibrium strategies when relations of stochastic dominance exist between valuation distributions

modeling competitive bidding a critical essay in analyzing bidding modeling matters this paper is a critical analysis of the models available to aid competitive bidding decision making bidding strategy and auction design in real transactions after an introductory overview this paper describes the contexts in which auctions arise reviews the mainstream theory of single isolated auctions and discusses the important work involved in enrichment of this theory in doing so it indicates results that have been obtained and the sort of changes in analytical approach that are needed to tackle other critical enrichments the paper summarizes briefly what is known about the direct use of models by bidders and auction designers a general theme of this paper is that enriched models are needed to bring bidding theory closer to direct applicability in decision making

procurement favouritism and technology adoption abstract it is well known that the design of cost minimizing procurement rules for the selection of a contractor among distinct technological groups requires the favouritism of inefficient firms in this paper i show that if technology adoption is non contractible these policies will also provide optimal incentives for the inefficient firms to adopt more efficient technologies

are bid preferences benign the effect of small business subsidies in highway procurement auctions abstract bid preferences in procurement auctions allow firms from an identifiable group an advantage in bidding against unfavored firms while economic efficiency is expected to fall as a result of bid preferences government procurement costs may either increase or decrease depending on the competitive response of favored and unfavored firms this paper uses data from california auctions for road construction contracts where small businesses receive a 5 percent bid preference in auctions for projects using only state funds and no preferential treatment on projects using federal aid i show that while firms bidding behavior matches theoretical predictions procurement costs are 3 8 percent higher on auctions using preferences the higher procurement cost in preference auctions is attributed to reduced participation by lower cost large firms structural estimates of latent firm costs are then used to evaluate how efficiency and the division of surplus between firms and the government are impacted by bid preferences firm profits are 3 1 percent lower under bid preferences however this is overwhelmed by the efficiency loss due to reduced large firm participation the efficiency loss conditional on firm participation is estimated to represent around 0 1 percent of overall procurement costs including the adverse effect of preferences on the participation of large firms increases the estimated efficiency loss to 3 6 percent which represents 27 cents for each additional dollar awarded to small businesses through the program counterfactual simulations indicate that if participation were instead inelastic to bid preferences the 5 percent bid preference would be close to the optimal level

towards supply chain sustainability economic environmental and social design and planning abstract costumers and governments are pressuring companies to become more sustainable however the lack of research on how to incorporate these issues makes this a challenging task to fill this gap a generic multi objective mathematical programming model for the design and planning of supply chains integrating the three dimensions of sustainability is presented the economic pillar of sustainability is addressed in this work considering the costs of the supply chain then recipe an environmental assessment methodology indicated in the literature and by the european commission as the most developed one currently available is for the first time applied to supply chain design optimization finally a social indicator appropriate to assess strategic decisions is proposed this social indicator considers the impact of social and political concerns on company s performance the relevance of this model as a decision support system is highlighted with its application to a real case study of a portuguese battery producer and distributor a set of strategies to select the best solution among the obtained optimal ones is presented results show that the model allows improvements in all the three dimensions of sustainability and offers important managerial insights
