Joint coordination contract for capital-constrained supply chains under asymmetric information

A two-echelon supply chain considering capital constraints and asymmetric information is established. The supplier provides credit guarantees for the capital-constrained retailer to loan from the bank, and its information about the retailer's capital type is asymmetric. The equilibrium decisions of supply chain participants are analyzed by using the Stackelberg game theory and principal–agent theory. Then, a joint contract is designed to eliminate the double marginalization effect. The results show that the supplier and the bank make different decisions for different types of retailers to avoid adverse selection. The joint contract of revenue-sharing and transfer payment can coordinate the supply chain.     

Dynamic contracting under imperfect public information and asymmetric beliefs

We develop a dynamic principal–agent model to show how imperfect public information and asymmetric beliefs about payoff-relevant parameters, agency conflicts, and the agent's implicit incentives to influence the principal's posterior beliefs through his unobservable actions interact to affect optimal dynamic contracts. We make a methodological contribution to the literature by solving the continuous-time contracting problem using a discrete-time approximation approach. We obtain a simple characterization of optimal renegotiation-proof contracts in terms of the solution to a nonlinear ordinary differential equation (ODE). We then exploit the properties of the ODE to derive a number of novel implications for the dynamics of long-term contracts that alter the intuition gleaned from the previous literature. Optimism has a first-order impact on incentives, investment and output that could reconcile the “private equity” puzzle. Consistent with empirical evidence, the interaction between asymmetric beliefs, risk-sharing and adverse selection costs could cause the time-paths of the agent's incentive intensities to be increasing or decreasing. Our results also suggest that the incorporation of imperfect public information and asymmetric beliefs could potentially reconcile empirical evidence of an ambiguous relation between risk and incentives, and a non-monotonic relation between firm value and incentives. Permanent and transitory components of risk have differing effects on incentives, which suggest that empirical investigations of the link between risk and incentives should appropriately account for different components of risk.     

Political contestability and public contract rigidity: An analysis of procurement contracts

Are public contracts less adaptable than private contracts? Using a comprehensive set of contracts for a standard product, we compare procurement contracts in which the procurer is either a public administration or a private corporation. We find that public‐to‐private contracts feature more rigidity clauses than private‐to‐private contracts and that the use of rigidity clauses in public contracts rises when political risks are more salient. We argue that a significant part of the increased rigidity of public contracts is a contractual adaptation to limit political hazards from political opponents and interested third parties.     

Organizational design in public procurement: A stakeholder approach

Organizing the purchasing function for public bodies and other non-profit and/or non-market bodies starts with the selection of an appropriate organizational strategy. In order to be able to select between generic strategies like low cost and differentiator or strategies described as operational excellence, customer intimacy and product leadership, a stakeholder based model was used. The selected strategy forms the basis to design the nature of three organizational elements: policies (P), organization (O) and processes (P). The aspect system of the purchasing function and the sub-system of the purchasing department reflect the nature of these three POP elements. It helps to translate the selected organizational strategy into a appropriate supplier strategy and clarifies the idealized mix of suppliers in terms of portfolio archetypes. Ten policy aspects of purchasing and four organizational aspects are described to redesign purchasing.     

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.     

A mechanism design approach to an optimal contract under ex ante and ex post private information

This paper applies a mechanism design approach to the problem of an optimal contract when one party has both ex ante and ex post private information. With ex ante private information added to the costly state verification environment, the timing of the contract is important in achieving the first-best investment decision. It is shown that an optimal contract involves precommitment, a feature often observed in many bank loan contracts. An optimal contract thus obtained is interpreted as t he golden parachute, a device providing incentives to managers not to distort the running of a firm to fight takeover bids. In the process of characterizing an optimal contract, the revelation principle is re-examined. Received: 12 April 1996 / Accepted: 3 December 1997     

Mandate Versus Championship: Vertical government intervention and diffusion of innovation in public services in authoritarian China

This research focuses on innovation and its diffusion in public services in authoritarian China. A mechanism between vertical government intervention and diffusion of innovation in public services is established by conducting a comparative case study between Sichuan and Tianjin. Administrative commands facilitate the formation of the ‘mandatory policy diffusion’ that rapidly diffuses policy instruments. Competition in the performance evaluation-based personnel system contributes to the formation of ‘championship policy diffusion’, which leads to the divergence of policy instruments in neighbouring local governments. Therefore, classic theoretical hypotheses on geographical proximity, competition, and vertical intervention concerning innovation diffusion need to be modified.     

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.

Caught in an evaluatory trap: a dilemma for public services under NPFM

This paper presents a challenge to public sector managers, policy-makers and interested academics. Drawing on the findings of previous international comparative studies of new public financial management (NPFM) reforms, it concludes that public services and their providers are caught in an ‘evaluatory trap’. The continual promotion of NPFM reforms, despite their evident repeated failure to meet specified achievements, is argued to be generating a cycle of ever-decreasing public services at ever-increasing costs per service unit. As the legitimacy of public services increasingly rests on the need to be seen as efficient and effective and as definitions of efficiency frequently demand adoption of the latest set of NPFM reforms, it follows that the future for public services is in question.     

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.     

Determinants of government underfunded public pension liabilities in the OECD

Underfunded government liabilities for public pensions constitutes a major expenditure in the management of social programmes in many countries, but to date has not attracted much attention from accountants as it does not easily fit within an accrual-based accounting system. This paper discusses major measurement problems associated with this liability and then examines determinants of variations in projected flow-based funding patterns among OECD governments. Alternative ‘behavioural persistence’ and ‘regression to the mean’ hypotheses about the determinants of underfunding practices are formulated and tested using an OECD data set describing the financial and socio-economic characteristics of government-sponsored public pension systems in these countries. Consistent with the behavioural persistence hypothesis, cross-sectional variations are found to be associated with the funding ratio and the rate of taxation required to keep government debt constant. Variations in underfunding practices across the sample are also sensitive to cultural differences in attitude towards public pension accountability between continental European and Anglo-American countries.     

Sustainability challenges in public health sector procurement: An application of interpretative structural modelling

Sustainable procurement is an integral part of public sector sustainability, but developing countries are far behind in this area. This study explores the internal and external challenges in Pakistan's public health sector that hamper sustainable procurement. With the help of experts, we found eleven key challenges that hamper sustainability in public health sector procurement. We designed an instrument and fielded it to eighty-five procurement officials in government hospitals, who verified the presence of the challenges in health sector. The interpretative structural modelling (ISM) we used to develop a hierarchy among the identified challenges reflects that government regulations and senior management's commitment—all strategic challenges—are the most critical challenges, whereas perceived ineffectiveness, third-party involvement, and the unavailability of green products—all operational challenges—are less critical. The study presents comprehensive recommendations to policymakers and future researchers related to achieving sustainable development goals in the health sector.     

Preventing rather than punishing: An early warning model of malfeasance in public procurement

Is it possible to predict malfeasance in public procurement? With the proliferation of e-procurement systems in the public sector, anti-corruption agencies and watchdog organizations have access to valuable sources of information with which to identify transactions that are likely to become troublesome and why. In this article, we discuss the promises and challenges of using machine learning models to predict inefficiency and corruption in public procurement. We illustrate this approach with a dataset with more than two million public procurement contracts in Colombia. We trained machine learning models to predict which of them will result in corruption investigations, a breach of contract, or implementation inefficiencies. We then discuss how our models can help practitioners better understand the drivers of corruption and inefficiency in public procurement. Our approach will be useful to governments interested in exploiting large administrative datasets to improve the provision of public goods, and it highlights some of the tradeoffs and challenges that they might face throughout this process.     

Full disclosure of tender evaluation models: Background and application in Portuguese public procurement

Public procurement rules in the European Union require that public contracting authorities must publish all tender evaluation criteria and its weights in advance. In order to define sound weights, the authors argue that the scoring rules for all evaluation criteria must be defined beforehand. Furthermore, the authors further argue that those scoring rules should also be published, in order to provide much more relevant and meaningful information for tenderers when preparing their tenders. Based on these evidences, the Portuguese Public Contracts Code compels public contracting authorities in Portugal to publish the comprehensive tender evaluation model in advance. This paper presents the Code, outlines the feasibility of establishing such a model in advance, addresses detailed instructions on how to go about in developing and applying it, and submits that existing European provisions on public procurement could yet go further in ensuring effective transparency, competition and best value for money tenders.     

Service specification in pre-tender phase of public procurement - A triadic model of meaningful involvement

The purpose of this research is to define the actor roles and collaborative practices that are central to service specification co-development in relation to the pre-tender phase of public procurement. We propose a new model of meaningful stakeholder involvement in the context of public service specification as a triadic setting. In addition to the theoretical value, the proposed model guides public procurement units on how to define their roles as intermediaries and to design a service specification process involving internal customers and providers of a service. The approach adopted highlights the meaningfulness of involvement by referring to the types of cooperative roles and practices that are both suitable for the situation and well understood and implemented by the cooperative parties. Service specification co-development is defined as a triadic setting involving buyers, service providers, and internal customers. This study consists of two longitudinal empirical public procurement cases viewed with the aid of a theoretical framework drawn from the general involvement and public-sector-specific involvement literature. Managerial implications relate to involving stakeholders early in the process, focusing on value creating activities, and sharing relevant information throughout the pre-tender phase.     

The long shadow of public policy; Barriers to a value-based approach in healthcare procurement

Procurement in the UKs National Health Service (NHS) is facing its most significant financial challenge. Despite the sheer scale and complexities of the public healthcare sector, the Government's solutions are all too often packaged as "collaborate more", "standardise products" and "leverage spend". Unfortunately, these over simplistic solutions take a myopic view of market drivers, conflate spend with potential savings and fail to deliver value. Many contracts have already been commercially optimised yet the funding crisis continues to deepen. New value-based procurement approaches are needed to drive longer-term innovation and cost reduction and to move debates from efficiencies to embrace effectiveness in integrated supply chains. In this research, we adopt the resource-based view (RBV) as a lens to explore the extent to which NHS resources support the strategic adoption of value-based approaches. An empirical case study on a regional cluster of six NHS Trusts in England, confirms the dominance of narrow price-based approaches that create barriers to moving towards longer-term, valuebased procurement. The antecedent roots of price-based approaches are unpicked through a hermeneutic analysis of recent Government commissioned reports to show how these have set the tone, culture and priorities for healthcare procurement in the UK. The analysis provides explanatory power to the case study by illustrating how Government reports have led to, and legitimised the dominance of price-based approaches and caused relational and resource-based barriers to adopting value-based procurement, despite stakeholder enthusiasm. The findings provide unique insights into why public procurement has struggled to reach beyond its traditional cost orientated scope. We contribute to an extended consideration of the RBV in public organisations through identifying the role of the policy environment in determining and legitimatising an organisation's strategic direction.     

Public–private partnership—Development of long-term relationships in public procurement in Germany

Hybrid partnerships are well established in the private sector combining market efficiency with the possibility of hierarchical steering mechanisms. By implementing Public–Private Partnerships (PPPs), public authorities seek to benefit from cooperation with specialised suppliers. However, many complex factors, including legal regulations, have to be considered in relation to outsourcing activities in the public sector. The decision on public–private cooperation is not driven only by economic principles. This paper deals with the economic and legal decision process of PPPs. The theoretical and legal framework is then applied and illustrated through a case study of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt e.V./DLR).

Changes in public employment and the provision of public services: the implications for labour law

Workers in the public sector have commonly been subject to a more restrictive labour law regime than their private sector counterparts. This article argues that this has become anachronistic and proposes a more sophisticated model for according differential treatment to particular groups of workers.
