Fairness in Selling to the Newsvendor

This paper studies the impact of fairness concerns on supply chain performance (SCP) in the two‐party newsvendor setting. We extend prior fairness analysis to a wide range of demand distributions, and also allow the degree and definition of fairness to assume a broader range of preferences than those in prior literature. Contrary to prior literature, we find that if the retailer's ideal allocation to the supplier is not sufficiently large, regardless of demand variability, a fair‐minded retailer makes no difference to system efficiency when facing a traditional profit‐maximizing supplier. Only when the retailer's ideal allocation to the supplier is above a threshold can the retailer's fairness concern improve the system efficiency for sufficiently high demand uncertainty. In order for the retailer's fairness concern to improve expected profits of both parties compared to the traditional supply chain case (win–win), the demand uncertainty cannot be too low, the retailer is not very averse to disadvantageous inequity, and his ideal allocation to the supplier is within a specific range. If only the supplier is concerned for fairness, the results range from worsening to improving (but not coordinating) the system and a win–win situation is impossible. Finally, when both the supplier and retailer are fair‐minded, SCP is improved unless both parties prefer to allocate small portions of system profit to the other. Again, win–win will be achieved only when the demand uncertainty is sufficiently high, the retailer's ideal allocation is within a certain range, and he is not very averse to disadvantageous inequity.     

REDISTRIBUTION,PORK, AND ELECTIONS

Why might citizens vote against redistributive policies from which they would seem to benefit? Many scholars focus on ‘wedge’ issues such as religion or race, but another explanation might be geographically‐based patronage—or pork. We examine the tension between redistribution and patronage with a model that combines partisan elections across multiple districts with legislation in spatial and divide‐the‐dollar environments. The model yields a unique equilibrium that describes the circumstances under which poor voters support right‐wing parties that favor low taxes and redistribution, and under which rich voters support left‐wing parties that favor high taxes and redistribution. The model suggests that one reason standard tax and transfer models of redistribution often do not capture empirical reality is that redistributive transfers are a less efficient tool for attracting votes than are more targeted policy programs. The model also underlines the central importance of party discipline during legislative bargaining in shaping the importance of redistribution in voter behavior, and it describes why right‐wing parties should have an advantage over left‐wing ones in majoritarian systems.     

Relational Contracts and the Nature of Market Interactions

We provide evidence that long‐term relationships between trading parties emerge endogenously in the absence of third party enforcement of contracts and are associated with a fundamental change in the nature of market interactions. Without third party enforcement, the vast majority of trades are initiated with private offers and the parties share the gains from trade equally. Low effort or bad quality is penalized by the termination of the relationship, wielding a powerful effect on contract enforcement. Successful long‐term relations exhibit generous rent sharing and high effort (quality) from the very beginning of the relationship. In the absence of third‐party enforcement, markets resemble a collection of bilateral trading islands rather than a competitive market. If contracts are third party enforceable, rent sharing and long‐term relations are absent and the vast majority of trades are initiated with public offers. Most trades take place in one‐shot transactions and the contracting parties are indifferent with regard to the identity of their trading partner.     

DOES RELATIONSHIP SPECIFIC INVESTMENT DEPEND ON ASSET OWNERSHIP? EVIDENCE FROM A NATURAL EXPERIMENT IN THE HOUSING MARKET

In this paper, I test the most basic prediction of Grossman and Hart (1986, The Costs and Benefits of Ownership: A Theory of Vertical and Lateral Integration. Journal of Political Economy, 691–719): allocations of asset ownership that expose a party to ex‐post expropriation reduce this party’s ex‐ante relationship‐specific investments. In the empirical context of the German housing market, I find that relationship‐specific investments, such as bathroom renovations, are more frequent if the occupant is protected against expropriation because he owns his home. To avoid the endogeneity of the homeownership allocation, I rely on the natural experiment of the German reunification: under the communist regime, ownership existed but was economically meaningless; yet after reunification, ownership unexpectedly reacquired legal force.     

AMBIVALENT INVESTMENT AND THE HOLD‐UP PROBLEM

In this paper we add to the foundations of incomplete contracting literature. We study the hold‐up problem with ambivalent investment, where investment benefits the investing party if ex post the right decision is undertaken but harms the investing party if the wrong decision is made. In this context, we show that the power of contracts to provide investment incentives depends on three factors: the commitment value of contracts, the amount of quasirents that the investing party can expect in the case of out‐of‐contract renegotiation, and the degree of ambivalence of investment. First, contracts provide first‐best investment incentives when parties can commit to a contract regardless of the type of investment. Second, with sufficiently ambivalent investment, if parties cannot commit not to renegotiate a contract and if the investing party's bargaining power is intermediate, contracts cannot improve investment incentives above those provided by no contract. In contrast, a simple buyer or seller option contract is optimal when the investing party's bargaining power is extreme. (JEL: D23, K12, L22)     

Allocation and Pricing of Substitutable Goods: Theory and Algorithm

Motivated by the thriving market of online display advertising, we study a problem of allocating numerous types of goods among many agents who have concave valuations (capturing risk aversion) and heterogeneous substitution preferences across types of goods. The goal is both to provide a theory for optimal allocation of such goods, and to offer a scalable algorithm to compute the optimal allocation and the associated price vectors. Drawing on the economic concept of Pareto optimality, we develop an equilibrium pricing theory for heterogeneous substitutable goods that parallels the pricing theory for financial assets. We then develop a fast algorithm called SIMS (standardization‐and‐indicator‐matrix‐search). Extensive numerical simulations suggest that the SIMS algorithm is very scalable and is up to three magnitudes faster than well‐known alternative algorithms. Our theory and algorithm have important implications for the pricing and scheduling of online display advertisement and beyond.     

Optimal Resource Allocation for Defense of Targets Based on Differing Measures of Attractiveness

This article describes the results of applying a rigorous computational model to the problem of the optimal defensive resource allocation among potential terrorist targets. In particular, our study explores how the optimal budget allocation depends on the cost effectiveness of security investments, the defender's valuations of the various targets, and the extent of the defender's uncertainty about the attacker's target valuations. We use expected property damage, expected fatalities, and two metrics of critical infrastructure (airports and bridges) as our measures of target attractiveness. Our results show that the cost effectiveness of security investment has a large impact on the optimal budget allocation. Also, different measures of target attractiveness yield different optimal budget allocations, emphasizing the importance of developing more realistic terrorist objective functions for use in budget allocation decisions for homeland security.     

基于讨价还价的私募基金机制比较研究

作为私募基金的主要形式，有限合伙制具有比公司制更高的激励作用，原因可能是两者在契约设计上的不同。本文引入讨价还价模型对公司制与有限合伙制进行分析，求解了两种机制下的均衡契约。研究发现，股东(或有限合伙人)和经理(或普通合伙人)之间的博弈等价于包含外部选择的讨价还价博弈，当经理保留收益不断提高，有限合伙制将逐步取代公司制。进一步地，有限合伙制将给出更高的分成比例，进而实现更高的激励，更有效地利用人力资本。     

CEO Duality,Agency Costs,and Internal Capital Allocation Efficiency

This study examines the impact of CEO duality on firms’ internal capital allocation efficiency. We observe that when the CEO is also chair of the board, diversified firms make inefficient investments, as they allocate more capital to business segments with relatively low growth opportunities over segments with high growth opportunities. The adverse impact of CEO duality on investment efficiency prevails only among firms that face high agency problems, as captured by high free cash flows, staggered board structure and low board independence. Depending on the severity of the agency problem, CEO duality is associated with a decrease in industry‐adjusted investment in high‐growth segments of 1% to 2.1% over the following year, relative to that in low‐growth segments. However, CEOs’ equity‐based compensation curbs the negative effect of CEO duality on internal capital allocation efficiency. Overall, the findings of this study offer strong support for the agency theory and postulate the internal capital allocation policy as an important channel through which CEO duality lowers firm value in diversified firms.     

Designing Supply Contracts Considering Profit Targets and Risk

Managers at all stages of a supply chain are concerned about meeting profit targets. We study contract design for a buyer–supplier supply chain, with each party maximizing expected profit subject to a chance constraint on meeting his respective profit target. We derive the optimal contract form (across all contract types) with randomized and deterministic payments. The best contract has the property that, if the chance constraints are binding, at most one party fails to satisfy his profit target for any given demand realization. This implies that “least risk sharing,”that is, minimizing the probability of outcomes for which both parties fail to achieve their profit targets, is optimal, contrary to the usual expectations of “risk sharing.” We show that an optimal contract can possess only two of the following three properties simultaneously: (i) supply chain coordination, (ii) truth‐telling, and (iii) non‐randomized payments. We discuss methods to mitigate the consequent implementation challenges. We also derive the optimal contract form when chance constraints are incorporated into several simpler and easier‐to‐implement contracts. From a numerical study, we find that an incremental returns contract (in which the marginal rebate rate depends on the return quantity) performs quite well across a relatively broad range of conditions.     

Advance Selling by a Newsvendor Retailer

Retailers often face a newsvendor problem. Advance selling helps retailers to reduce demand uncertainty. Consumers, however, may prefer not to purchase in advance unless given a discount because they are uncertain about their valuation for the product in advance. It is then unclear whether or when advance selling to pass some uncertainty risk to consumers is optimal for the retailer. This paper examines the advance selling price and inventory decisions in a two‐period setting, where the first period is the advance selling period and the second is the selling (and consumption) period. We find that an advance selling strategy is not always optimal, but is contingent on parameters of the market (e.g., market potential and uncertainty) and the consumers (e.g., valuation, risk aversion, and heterogeneity). For example, we find that retailers should sell in advance if the consumers' expected valuation exceeds consumers' expected surplus when not buying early by a certain threshold. This threshold increases with the degree of risk aversion but decreases with stock out risk. If the degree of risk aversion varies across consumers, then a retailer should sell in advance if the probability for a consumer to spot buy is less than a critical fractile.     

Supply Chain Strategies and International Tax Arbitrage

What motivates the geographic footprint of the supply chains that multinational firms (MNFs) deploy? Traditional research in the operations and supply chain management literature tends to recommend locations primarily based on differentials in production costs and the ramifications of physical distance ignoring the role of taxation. MNFs that strategically position parts of their supply chains in low‐tax locations can allocate the profits across the divisions to improve post‐tax profits. For the profit allocation to be defensible to tax authorities, the divisional operations must possess real decision authority and bear meaningful risks. Generally speaking, the greater the transfer of risk and control, the larger the allowable allocation of profit. These transfers may also create inefficiencies due to misalignment of business goals and attitudes toward risk. We model these trade‐offs in the context of placing in a low‐tax region a subsidiary that oversees product distribution (as a limited risk distributor commissionnaire, limited risk distributor, or fully fledged distributor). Our analysis demonstrates that the MNF's preferences regarding the operating structures are not necessarily an obvious ordering based on the amount of risk and decision authority transferred to the division in the low‐tax jurisdiction. We derive and analyze threshold values of the performance parameters that describe the main trade‐offs involved in selecting an operating structure. We find some of the optimal decisions to exhibit interesting non‐monotone behavior. For instance, profits can increase when the tax rate in the low‐tax jurisdiction increases. Numerical analysis shows that the Limited‐Risk Distributor structure is rarely optimal and quantifies when each alternative dominates it.     

Buyer–Supplier Performance: The Role of Asset Specificity,Reciprocal Investments and Relational Exchange

This paper argues that the extent and balance of transaction specific assets, and the presence of relational norms in a buyer–supplier relationship are important factors affecting partnership performance. Hypotheses were tested using data from 393 manufacturing firms. Results revealed that while specific investments by one participant in the relationship negatively impacted the indicators of performance, offsetting investments by the other party effectively increased performance. Relational-exchange elements were positively related to performance.     

A PLURALITY MAXIMIZING APPROACH TO THE ALLOCATION OF CAMPAIGN RESOURCES

An important problem in the planning of political campaigns is the allocation of resources to precincts and other geographical voting units in order to maximize a candidate's plurality. Essentially, parties may increase candidate plurality by engaging in registration drives, midcampaign activities such as canvassing and candidate appearances, and get-out-the-vote drives. Based on previous work which has related voter response to party identification, the authors develop a model for the optimal allocation of campaign resources to these activities. The computational feasibility of the solution procedure is made possible by a decomposition across activities.     

Examining the Antecedents and Consequences of CIO Strategic Decision‐Making Authority: An Empirical Study*

Despite the strategic importance of information technology (IT) to contemporary firms, chief information officers (CIO) often still have varying degrees of strategic decision‐making authority. In this study, we apply the theory of managerial discretion to define CIO strategic decision‐making authority and argue that the CIO's level of strategic decision‐making authority directly influences IT's contribution to organization performance. We also draw on the power and politics perspective in the strategic decision‐making literature to identify the direct antecedents to the CIO's strategic decision‐making authority. A theoretical model is presented and empirically tested using survey data collected from a cross‐industry sample of 174 matched pairs of CIOs and top business executives through structural equation modeling. The results suggest that organizational climate, organizational support for IT, the CIO's structural power, the CIO's level of strategic effectiveness, and a strong partnership between the CIO and top management team directly influence the CIO's level of strategic decision‐making authority within the organization. The results also suggest that the CIO's strategic decision‐making authority in the organization directly influences the contribution of IT to firm performance and that effective CIOs have a greater influence on IT's contribution when provided with strategic decision‐making authority.     

NORM ENFORCEMENT: ANGER,INDIGNATION, OR RECIPROCITY?

The enforcement of social norms often requires that unaffected third parties sanction offenders. Given the renewed interest of economists in norms, the literature on third‐party punishment is surprisingly thin. In this paper, we report the results of an experiment designed to replicate the anger‐based punishment of directly affected second parties and evaluate two distinct explanations for third‐party punishment: indignation and group reciprocity. We find evidence in favor of both, with the caveat that the incidence of indignation‐driven sanctions is perhaps smaller than earlier studies have hinted. Furthermore, our results suggest that second parties use sanctions to promote conformism while third parties intervene primarily to promote efficiency.     

THIRD-PARTY REACTIONS TO EMPLOYEE (MIS)TREATMENT: A JUSTICE PERSPECTIVE

To date, theory and research on organizational justice has tended to focus on the victim’s (i.e. the employee’s) perspective; the third party’s perspective has received relatively little systematic attention. In this chapter we develop a model describing how third parties make fairness judgments about an employee’s (mis)treatment by an organization or its agents (including supervisors and peers). Our model also identifies factors that can predict whether third parties will act on their unfairness perceptions. We identify several distinctions between the victim’s and third party’s perspectives. We conclude by explaining how the third party’s perspective offers numerous opportunities and challenges for research.     

Market Good Flexibility in Capacity Auctions

We consider the allocation of limited production capacity among several competing agents through auctions. Our focus is on the contribution of flexibility in market good design to effective capacity allocation. The application studied is a capacity allocation problem involving several agents, each with a job, and a facility owner. Each agent generates revenue by purchasing capacity and scheduling its job at the facility. Ascending auctions with various market good designs are compared. We introduce a new market good that provides greater flexibility than those previously considered in the literature. We allow ask prices to depend both on agents’ utility functions and on the number of bids at the previous round of the auction, in order to model and resolve resource conflicts. We develop both optimal and heuristic solution procedures for the winner determination problem. Our computational study shows that flexibility in market good design typically increases system value within auctions. A further increase is achieved if each agent is allowed to bid for multiple market goods at each round. On average, the multiple flexible market goods auction provides over 95% of the system value found by centralized planning.     

Package Auctions and Exchanges

We report recent advances concerning the package allocation problem, in which traders seek to buy or sell combinations of goods. The problems are most difficult when some goods are not substitutes. In that case, competitive equilibrium typically fail to exist but the core is non‐empty and comprises the competitive solutions. Also in that case, the Vickrey auction fails to select core allocations and yield revenues that are less than competitive. The Ausubel‐Milgrom auction generally selects core allocations and, when goods are substitutes, prescribes the Vickrey allocation. We also evaluate the problems and promise of mechanisms for the package exchange problem.     

Market‐Based Allocation with Indivisible Bids

We study multiunit double auctions accepting bids with indivisibility constraints. Modeling the auction problem as a Multiple Choice Knapsack Problem and using dynamic programming, we show that incremental computations during bid processing can speed the handling of key auction operations such as clearing and quoting. We propose different price‐quote policies and study their influence on the efficiency of market‐based allocation. Using a reconfigurable manufacturing scenario where agents trade large quantities of multiple goods, we demonstrate potential benefits of supporting indivisibility constraints in bidding. These benefits are highly sensitive to the form of price quote provided, indicating interesting tradeoffs in communication and allocation efficiency.
