Royalty licensing

Most patent licensing agreements observed empirically include either per-unit or ad valorem royalties. The theoretical literature generally focuses on per-unit royalties. We provide a simple justification for the presence of ad valorem royalties in licensing contracts.     

Current account sustainability in the US: What did we really know about it?

We analyze the sustainability of the US current account (CA) deficit by means of unit-root tests. First, we argue that there are several reasons to believe that the CA may follow a non-linear mean-reversion behavior under the null of stationarity. Using a non-linear ESTAR model we can reject the null of non-stationarity favoring the sustainability hypothesis. Second, we ask whether unit-root tests are a useful indicator of sustainability by comparing in-sample results for the 1960–2004 period to the developments observed up to the end of 2008. We find that the non-linear model outperforms the linear and random walk models in terms of forecast performance. The large shocks to the CA observed in the last five years induced a faster speed of mean reversion, ensuring the necessary adjustment to meet the inter-temporal budget constraint.     

Applying a third party access model for China’s gas pipeline network: an independent pipeline operator and congestion rent transfer

This paper investigates third party access regulatory issues in China’s natural gas industry. We study the development of China’s gas market-oriented reform and how third party access becomes a pressing issue in that context. This paper aims to report stakeholders’ benefit and distributional effects during a hypothetical third party access process. To that end, we apply an oligopolistic equilibrium model, based on the mixed complementarity problem, to China’s gas pipeline network. We compare two scenarios: a scenario without third party access and the other scenario where an independent pipeline operator optimizes flows. This latter scenario aims to guarantee that the maximum social benefit is achieved. In addition, the latter scenario transfers the congestion rent to former integrated gas companies to compensate their actual loss control of the pipeline operation, in order to minimize the adverse distributional effects for pipeline companies. The solution of the model indicates that operational separation is feasible with Pareto improvement in China’s context. Moreover, it merits particular attention from policy makers in China that pipeline capacity scarcity should be properly evaluated and managed.     

Improvisation as “real time foresight”

The concept of improvisation, while now recognized in organization studies, has been neglected in strategy studies. We suggest that one of the reasons for this is the dominance of a structural view of strategy and competition. Alternative views, such as the Austrian school or those that stress the Red Queen effect, emphasize the process-based nature of competition. In fast-changing environments, speed and reaction are central attributes, which render the traditional separation between planning and execution untenable. In these contexts, improvisation, the convergence of planning and execution, becomes a paradoxical form of “real time foresight”: organizations screen trends, spot opportunities, actively wait and/or act with speed to seize the moment.     

Option implied cost of equity and its properties

The estimation of the cost of equity capital (COE) is one of the most important tasks in financial management. Existing approaches compute the COE using historical data, i.e. they are backward‐looking methods. This study derives a method to calculate forward‐looking estimates of the COE using the current market prices of stocks and stock options. Our estimates of the COE reflect the expectation of the market investors about the COE during the life of the investment project. We test empirically our method and compare it with the Fama/French (1993) three‐factor model for the S&P 100 firms. The empirical results indicate that our COE estimates (1) are plausible and stable over the years as required by appropriate discount rates for capital budgeting, (2) yield an equity risk premium close to the market equity risk premium reported by Fama E. F. and French K. R. (2002), (3) generate strong return‐risk relationships, and (4) are significantly related with investor sentiment. © 2009 Wiley Periodicals, Inc.

Does the Ethical Leadership of Supervisors Generate Internal Social Capital?

Ethics has recently gained prominence in debates surrounding social capital creation. Despite the significant theoretical progress in this field, it still lacks empirical research. The goal of this study is to empirically explore the ethical leadership of supervisors as an antecedent of the firm’s social capital. We build on social learning theory to argue that employees can learn standards of appropriate behavior by observing the behavior of role models. By displaying and enforcing ethical behavior, supervisors can facilitate the process through which employees learn to feel empathy toward others and establish profound affective relationships with them. Data were collected from 408 Spanish, French, and Portuguese part-time MBA students. Using structural equation modeling techniques, we show that the ethical leadership of supervisors exerts a significant influence on the structural, relational, and cognitive dimensions of social capital.

Leading and Following (Un)ethically in <Emphasis Type="Italic">Limen</Emphasis>

We propose a liminality-based analysis of the process of ethical leadership/followership in organizations. A liminal view presents ethical leadership as a process taking place in organizational contexts that are often characterized by high levels of ambiguity, which render the usual rules and preferences dubious or inadequate. In these relational spaces, involving leaders, followers, and their context, old frames may be questioned and new ones introduced in an emergent way, through subtle processes whose evolution and implications may not be easy to grasp even by those participating in them.     

Explicit vs. tacit collusion—The impact of communication in oligopoly experiments

We explore the difference between explicit and tacit collusion by investigating the impact communication has in experimental markets. For Bertrand oligopolies with various numbers of firms, we compare pricing behavior with and without the possibility to communicate among firms. We find strong evidence that talking helps to obtain higher profits for any number of firms, however, the gain from communicating is non-monotonic in the number of firms, with medium-sized industries having the largest additional profit from talking. We also find that industries continue to collude successfully after communication is disabled. Communication supports firms in coordinating on collusive pricing schemes, and it is also used for conflict mediation.
