    Reputation, Competition, and Entry in Procurement

    Based on my recent work with several co-authors this paper explores the relationship between discretion, reputation, competition and entry in procurement markets. I focus especially on public procurement, which is highly regulated for accountability and trade reasons. In Europe regulation constrains the use of past performance information to select contractors while in the US its use is encouraged. I present some novel evidence on the benefits of allowing buyers to use reputational indicators based on past performance and discuss the complementary roles of discretion and restricted competition in reinforcing relational/reputational forces, both in theory and in a new empirical study on the effects restricted rather than open auctions. I conclude reporting preliminary results form a laboratory experiment showing that reputational mechanisms can be designed to stimulate rather than hindering new entry.Accountability; Discretion; Entry; Incomplete contracts; Limited enforcement; Past performance; Procurement; Quality; Relational contracts; Reputation; Restricted auctions.

    Innovation Contests with Entry Auction

    Get PDF
    We consider procurement of an innovation from heterogeneous sellers. Innovations are random but depend on unobservable effort and private information. We compare two procurement mechanisms where potential sellers first bid in an auction for admission to an innovation contest. After the contest, an innovation is procured employing either a fixed prize or a first-price auction. We characterize Bayesian Nash equilibria such that both mechanisms are payoff-equivalent and induce the same efforts and innovations. In these equilibria, signaling in the entry auction does not occur since contestants play a simple strategy that does not depend on rivals' private information

    Information Disclosure in Procurement Auctions with Horizontally Differentiated Suppliers

    This work studies a model of multidimensional auction in which a buyer needs to procure a given good from either of two potential suppliers whose quality is the buyer's private information and whose production costs are heterogeneous. Costs asymmetries constitute a novelty in this framework and extend e.g. the model of Gal-Or et al. (2007). We compare the outcomes of different procurement policies from the viewpoint of both efficiency and the buyer's payoff. A trade-off between efficiency and rent-extraction emerges. The buyer will maximize her expected utility by selecting a first score auction and either concealing or privately revealing suppliers'quality - the optimal choice depending on the degree of heterogeneity in suppliers' costs and qualities. However, neither of these auction mechanisms will be efficient: efficiency calls for a second score auction or a first score auction with public disclosure of suppliersquality. The findings hinge on the equivalence between auction models and models of horizontal differentiation and take advantage of results for asymmetric auctions developed by Maskin & Riley (2000).multidimensional auctions, procurement policies, endogenous information, horizontal di¤erentiation, asymmetric auctions.

    Economics of intelligent selection of wireless access networks in a market-based framework : a game-theoretic approach

    Get PDF
    The Digital Marketplace is a market-based framework where network operators offer communications services with competition at the call level. It strives to address a tussle between the actors involved in a heterogeneous wireless access network. However, as with any market-like institution, it is vital to analyze the Digital Marketplace from the strategic perspective to ensure that all shortcomings are removed prior to implementation. In this paper, we analyze the selling mechanism proposed in the Digital Marketplace. The mechanism is based on a procurement first-price sealed-bid auction where the network operators represent the sellers/bidders, and the end-user of a wireless service is the buyer. However, this auction format is somewhat unusual as the winning bid is a composition of both the network operator’s monetary bid and their reputation rating. We create a simple economic model of the auction, and we show that it is mathematically intractable to derive the equilibrium bidding behavior when there are N network operators, and we make only generic assumptions about the structure of the bidding strategies. We then move on to consider a scenario with only two network operators, and assume that network operators use bidding strategies which are linear functions of their costs. This results in the derivation of the equilibrium bidding behavior in that scenario

    Non-conventional provisions in regional trade agreements : do they enhance international trade?

    Get PDF
    The scope of recent regional trade agreements (RTAs) is becoming much wider in terms of including several provisions such as competition policy or intellectual property. This paper empirically examines how far advanced, non-conventional provisions in RTAs increase trade values among RTA member countries, by estimating the gravity equation with more disaggregated indicators for RTAs. As a result, we find that the provision on competition policy has the largest impacts on trade values, following that on government procurement. Our further analysis reveals that the more significant roles of these two provisions can be also observed in the impacts on the intensive and extensive margins.International trade, International agreements, Gravity, RTA, Extensive and intensive margins

    Bid-Centric Cloud Service Provisioning

    Bid-centric service descriptions have the potential to offer a new cloud service provisioning model that promotes portability, diversity of choice and differentiation between providers. A bid matching model based on requirements and capabilities is presented that provides the basis for such an approach. In order to facilitate the bidding process, tenders should be specified as abstractly as possible so that the solution space is not needlessly restricted. To this end, we describe how partial TOSCA service descriptions allow for a range of diverse solutions to be proposed by multiple providers in response to tenders. Rather than adopting a lowest common denominator approach, true portability should allow for the relative strengths and differentiating features of cloud service providers to be applied to bids. With this in mind, we describe how TOSCA service descriptions could be augmented with additional information in order to facilitate heterogeneity in proposed solutions, such as the use of coprocessors and provider-specific services

    Contracting for Infrastructure Projects as Credence Goods

    Large infrastructure projects are a major responsibility of government, who usually lacks expertise to fully specify the demanded projects. Contractors, typically experts on such projects, advise of the needed design in their bids. Producing the right design is nevertheless costly. We model the contracting for such infrastructure projects taking into account this credence goods feature and examine the performance of commonly used contracting methods. We show that when building costs are public information, multistage competitive bidding involving shortlisting of two contractors and contingent compensation of both contractors on design efforts outperforms sequential search and the traditional Design-and-Build approach. While the latter leads to minimum design effort, sequential search suffers from a commitment problem. If building costs are the private information of the contractors and are revealed to them after design cost is sunk, competitive bidding may involve sampling more than two contractors. The commitment problem under sequential search may be overcome by the procurer's incentive to search for low building cost if the design cost is sufficiently low. If this is the case, sequential search may outperform competitive bidding.Credence Goods, Design-Build, Competitive Bidding, Sequential Search, Infrastructure Projects

    The Effective Use of Limited Information: Do Bid Maximums Reduce Procurement Cost in Asymmetric Auctions?

    Get PDF
    Conservation programs faced with limited budgets often use a competitive enrollment mechanism. Goals of enrollment might include minimizing program expenditures, encouraging broad participation, and inducing adoption of enhanced environmental practices. We use experimental methods to evaluate an auction mechanism that incorporates bid maximums and quality adjustments. We examine this mechanism’s performance characteristics when opportunity costs are heterogeneous across potential participants, and when costs are only approximately known by the purchaser. We find that overly stringent maximums can increase overall expenditures, and that when quality of offers is important, substantial increases in offer maximums can yield a better quality-adjusted result.
