Optimal procurement mechanisms for divisible goods with capacitated suppliers

Procurement auction literature typically assumes that the suppliers are uncapacitated [see, e.g. Dasgupta and Spulber in Inf Econ Policy 4:5–29, 1990 and Che in Rand J Econ 24(4):668–680, 1993]. Consequently, the auction mechanisms award the contract to a single supplier. We study mechanism design in a model where suppliers have limited production capacity, and both the marginal costs and the production capacities are private information. We provide a closed-form solution for the revenue maximizing direct mechanism when the distribution of the cost and production capacities satisfies a modified regularity condition [Myerson in Math Oper Res 6(1):58–73, 1981]. We also present a sealed low bid implementation of the optimal direct mechanism for the special case of identical suppliers. The results in this paper extend to other principle-agent mechanism design problems where the agents have a privately known upper bound on allocation.

Organizations undertaking complex projects in uncertain environments

Recent evidence suggests that firms’ environments are becoming more complex and uncertain. This paper investigates the relationship between the complexity of a firm’s activities, environmental uncertainty and organizational structure. We assume agents are arranged hierarchically, but decisions can be made at different levels. We model a firm’s activity set as a modified NK landscape. Via simulations, we find that centralized decision making generates a higher payoff in more complex and uncertain environments, and that a flatter structure is better for the organization with centralized decision making, provided the cost of information processing is low enough.

Managing risk and uncertainty in complex capital projects

In evaluating capital budgeting decisions, quantitative approaches, such as traditional discounted cash flow modeling and real options valuations, are useful when there is a presumed probability distribution for the future forecasted outcomes or for when there are lower levels of uncertainty. As uncertainty increases and forecasting becomes difficult, the value of financial modeling techniques decreases. Borrowing from the strategic management literature, we argue that it may be useful to employ a qualitative approach to evaluate capital projects when faced with high levels of uncertainty. In order to illustrate our argument, we use a derivative of scenario planning and qualitative real options to evaluate non-quantifiable factors in a project for the National Ignition Facility.     

On the dynamic selection of mechanisms for provision of public projects

How do individuals' spatial decisions affect the institutions for public goods provision over time? This paper describes a dynamic model in which the provision mechanism for a public project is itself the object of locational choice of individuals. Individuals in an ongoing society must choose between a location with a Majority Rule mechanism and one with a Voluntary Contribution mechanism. Each mechanism determines a funding decision for a local public project which is repeated over time. Generations of individuals asynchronously supercede their ‘parents’, creating an entry/exit process that allows individuals with possibly different beliefs to enter society. A self-confirming equilibrium (SCE) belief process describes an evolution of beliefs in this society consistent with a self-confirming equilibrium (Fudenberg and Levine, 1993) of the repeated location/provision game. It is shown that the process with belief mutation as new individuals enter society results in a globally absorbing state in which the Majority Rule mechanism is the unique survivor of the two.

Capability hierarchy in electronic procurement and procurement process performance: An empirical analysis

This paper examines the interrelationship between two hierarchically structured functional capabilities pertinent in the organizational procurement process, and the impact of these capabilities on procurement process performance. These functional capabilities operate at different levels in an organization's procurement process. We draw upon resource- and knowledge-based views of the firm to theorize that in this hierarchy of information technology-enabled procurement capabilities, the higher-level capability – procurement integration competence – enables firms to develop and deploy a lower-level capability – digital procurement competence. Further, we theorize that the lower-level capability impacts procurement process performance directly and completely mediates the relationship between higher-level capability and performance. Thus, although performance is impacted directly only by the lower-level capability, the higher-level capability facilitates the development and use of the lower-level capability. Our research model is tested using survey data from a large sample of 412 manufacturing firms. The results provide strong support for the proposed research model. In particular, we find that as hypothesized, the impact of procurement integration competence on performance is completely mediated by digital procurement competence. Our results suggest that when examined at the procurement process level, the impact of higher-level capabilities may be manifested completely through the lower-level capabilities. Theoretical and practical implications of the research are discussed.     

Promoting competitive markets: The role of public procurement

The study presented here examines how public procurement agencies address establishing and maintaining competitive markets; a topic still in its academic infancy. Cases are used to address impediments and improve understanding of strategic priorities in managing for competitive markets. Public policy academics have observed many competing policies in the wider public sector. Specifically, this paper identifies a need for research on supplier incentives at a market level, on the post contract management of suppliers and as an important sub-set, key supplier relationship management, along with professional development.     

Hybrid governance and governance performance in industrial purchasing relationships

Hybrid governance arrangements (e.g. joint action, long-term contracting and vertical coordination) feature regularly as an effective response to inter-firm dependence in the literature of business-to-business relationships. However, current empirical work has paid little attention to whether such governance arrangements really do improve governance efficacy and reduce transaction costs. The present study focuses on the governance efficacy of vertical coordination in industrial business-to-business relationships. Building on transaction costs arguments, the author examines whether vertical coordination is an effective means for adapting to inter-firm dependence, realized as the substantial employment of specific assets.Empirical findings from a survey of 170 industrial supplier–buyer relationships demonstrate that when asset specificity reaches a certain level, greater vertical coordination reduces ex post transaction costs significantly. On the other hand, this efficacy pattern is modest or non-existent in relationships with low asset specificity.The research findings support the basic TCA assumption that the performance of hybrid governance arrangements is highly dependent on a situation of substantial inter-firm dependence with subsequent small-number conditions.     

The analysis of government procurement in the frame of principal agent theory

In government procurement activities, asymmetric information, incomplete contracts and opportunism, led to the dysfunction of principal-agent. Through the reference of the principal-agent theory, this paper uses the model of the principal-agent to analyze government procurement activity, and proposes some countermeasures to improve principal-agent in government procurement.

Detection of collusion in government procurement auctions

Research on bidder collusion in procurement auctions is reasonably successful in unveiling the mechanisms of collusion among the bidders. But it is relatively weak in forwarding effective practical methods of collusion detection before the winner is declared, because they presuppose the knowledge of collusion in specific auctions. Past studies, however, point out the need for working with bid price-to-reserve price ratios rather than bid prices or winning bid prices, to be free from the problem of heteroscedasticity. They also draw an important inference that the set of collusive data are significantly different from the set of competitive data. On the basis of these basic facts, the current paper outlines a seven-step approach to collusion detection. The approach makes rudimentary statistical analysis of bid price-to-reserve price ratios for all the bidders. The analysis comprises tests of equality of means, medians and variance and tests of skewness, autocorrelation and normality of the ratios. It divides the ratios into two significantly different clusters. The cluster with the higher mean and variance values of the ratios corresponds to collusive bidding with the other cluster corresponding to competitive bidding. The paper proposes the construction of a process control chart to detect occurrence of collusion in an auction immediately after the price bids are opened. The approach is illustrated by applying it to data from procurement auctions for construction projects in a State Department of the Republic of India.     

Innovative practices in public procurement partnerships: The case of the United States

Public procurement partnerships represent a new approach to conducting government acquisition. These partnerships are predicated on the notion that governments today simply lack the requisite knowledge, skills and financing to provide core public services and acquire sophisticated services, IT and knowledge development by themselves. Instead, governments need to enlist the collective energies of the governmental, business and non-profit (third) sectors. This research looks at the concept of public procurement partnerships in the United States and the major trends promoting their use. Two case examples of public procurement partnerships are presented; one from the perspective of a government partner, the other from the perspective of a private (third) sector partner.     

The shadow economy beyond European public governance

The purpose of this paper is to try to analyze the Shadow Economy (SE) and its determinants by means of the Structural Equation Model (SEM)-Partial Least Squares (PLS). The overall topic of the SEM-PLS approach is controversially debated in the literature. In the past decades, the focus on the SE has increased and the range in the estimated size of this phenomenon is very divergent. By examining the effects of a set of indicators, economic theory often emphasizes the need for lower taxes and less regulation, but many other factors, such as administrative quality, are frequently neglected. Policy implications are discussed. Estimates for the SE as a percentage of GDP can be calculated and European countries are clustered according to the obtained results.
