Nonparametric estimation of an instrumental regression: A quasi-Bayesian approach based on regularized posterior

We propose a quasi-Bayesian nonparametric approach to estimating the structural relationship φ$\phi$ among endogenous variables when instruments are available. We show that the posterior distribution of φ$\phi$ is inconsistent in the frequentist sense. We interpret this fact as the ill-posedness of the Bayesian inverse problem defined by the relation that characterizes the structural function φ$\phi$. To solve this problem, we construct a regularized posterior distribution, based on a Tikhonov regularization of the inverse of the marginal variance of the sample, which is justified by a penalized projection argument. This regularized posterior distribution is consistent in the frequentist sense and its mean can be interpreted as the mean of the exact posterior distribution resulting from a Gaussian prior distribution with a shrinking covariance operator.     

Partnering relationships in construction: A literature review

There is no unified view as to what partnering relationships are in the construction industry. The purpose of this paper is to examine the literature in order to identify the main assumptions about partnering relationships in construction research and practice. The literature is compared to the Construction Industry Institute’s (CII, 1991) frequently cited definition of partnering as a long-term commitment between two or more parties in which shared understanding and trust develop for the benefits of improving construction. The literature review reveals a tendency to focus on project partnering in dyads between clients and contractors and there is also an emphasis on formal tools to develop these relationships, even if social aspects and relationship dynamics are recognised. The paper discusses these findings and suggests that, in order to increase the understanding of the substance and function of partnering relationships, it could be useful to incorporate knowledge from theoretical perspectives that are more in line with the CII definition. Two perspectives that seem particularly interesting in this respect are Supply Chain Management (SCM) and the Industrial Network Approach (INA), both of which focus on long-term relationships between actors beyond the dyad. INA also emphasises the informal aspects of relationship development. Incorporating these dimensions of partnering relationships requires processual and longitudinal studies, which are relatively rare in the contemporary partnering literature.

Franchising and intellectual capital: A franchisee’s perspective

Various studies have focused on the reasons for franchising. Most studies have concentrated principally on the franchisors’ motivations for franchising, with only a few exploring franchising as a route to self-employment. This paper seeks to provide a conceptual framework which examines the value of franchising to franchisees, employing an intellectual capital perspective. It is suggested that the (perceived) value of the franchise system is unlikely to remain static over time, and that the perceived benefits of franchise systems will vary according to both system and franchisee attributes.

How Project Manager–Project Owner Interaction Can Work Within and Influence Project Risk Management

Inherent interest conflicts between a project management team and project owner are often neglected in project risk management. Risk management by the project management team basically focuses on project short‐term survival, or project success toward handover to the customer, while for the project owner, strategic success should be more important. To see how this takes place in and influences real projects, seven large projects were studied, and interaction in project risk management between the project owners and project management team was examined for each project. The study revealed that the main focus in the studied projects was on operational risks, even within the project owner's set of high‐priority risks.     

The effect of option granting on executive stock purchases

We provide a simple asymmetric information model showing that, in contrast to portfolio diversification arguments, there is a natural complementarity between executive options and stock ownership. Moreover, managers can be made worse off by being granted more executive options.     

Does innovation help the good or the poor performing firms?

Using firm-level innovation data we find surprising results on the benefits of innovation. Only manufacturing firms with below average productivity growth are likely to benefits significantly from successful innovation, while faster growing firms do not gain additional benefits from innovating.     

The OECD Anti-Bribery Convention: Changing the currents of trade

This paper examines how criminalizing the act of bribing a foreign public official affects international trade flows using a watershed global anti-corruption initiative — the 1997 OECD Anti-Bribery Convention. I exploit variation in the timing of implementation by exporting countries and in the level of corruption of importing countries to quantify the Convention's effects on bilateral exports. I use a large panel of country pairs to control for confounding global and national trends and shocks. I find that, on average, the Convention caused a reduction in exports from signatory countries to high corruption importers relative to low corruption importers. In particular, we observe a 5.7% relative decline in bilateral exports to importers that lie one standard deviation lower on the Worldwide Governance Indicators corruption index. This suggests that by creating large penalties for foreign bribery, the Convention indirectly increased transaction costs between signatory countries and high corruption importers. The Convention may have induced OECD firms to divert their exports to less corrupt countries; while non-OECD firms not bound by the Convention may have increased their exports to corrupt countries. I also find evidence that the Convention's effects differed across product categories.
