Should Independent Directors Have Term Limits? The Role of Experience in Corporate Governance

We examine the role of independent directors with extended tenure in board‐level governance, monitoring decisions, and advising outcomes. These directors exhibit a higher level of commitment as they attend more board meetings and take more committee memberships. Firms with a higher proportion of these directors have lower chief executive officer (CEO) pay, higher CEO turnover‐performance sensitivity, and a smaller likelihood of intentionally misreporting earnings. These firms also restrict the expansion of resources under the CEO's control as they are less likely to make acquisitions, while the acquisitions they do make are of higher quality. Efforts to impose term limits on directors may, therefore, be misguided.     

The development of IB as a scientific field

International business (IB) is today an established field in business studies with two professional associations and numerous academic publications. However, it is much younger than many other fields in the management area. Although economists were focusing on international issues even before, it was not until after the Second World War that IB started to emerge as a scientific field. The purpose of this paper is to analyse this development from the early days up to the present time. In so doing, using a theoretical framework, it focuses on the organizing of the field, i.e. how early informal contacts eventually led to the formation of formal organizations, the launching of journals, and with the passage of time the publishing of handbooks. The paper provides empirical evidence of all these steps. In this way it presents data on significant contributions to the field.     

Equilibrium price formation in markets with differentially informed agents

We consider a pure exchange economy with a finite set of types of agents which have incomplete and asymmetric information on the states of nature. Our aim was to describe the equilibrium price formation and analyze how the lack of information may affect the allocation of resources. To do so, we adapt to an asymmetric information scenario a variant of the Shapley–Shubik game introduced by Dubey and Geanakoplos (J Math Econ 39:391–400, 2003 ).     

Herd Behaviour in Adoption of Network Technologies

In technology adoption, herd behaviour can lead to a suboptimal outcome as shown, among others, by Choi (1997). However, empirics find little support for the idea that a less efficient technology can conquer the market and lock out a more efficient one. Accordingly, we improve and generalize Choi's results, by introducing an additional source of uncertainty: the economic environment. We investigate how the economic environment can affect herding and consequently the efficiency of the technology choice. The result is a smaller adoption bias. In the limit, firms may optimally experiment with the new technology that turns out to be social welfare improving.     

Volatility spill-overs in commodity spot prices: New empirical results

The classical rational expectations model of commodity markets implies that expected spot price risk is an explanatory variable in spot price regressions; and also that inventory carryover, which is reduced by a larger price variance, creates autoregressive conditional heteroscedastic processes in spot prices. In order to falsify/verify this theory, it has typically been assumed that the square root of the conditional variance of spot prices, a proxy for spot price risk, enters the conditional mean function of spot prices. Based on this simple representation, a typical but counter intuitive outcome has been that spot price risk has an insignificant impact on spot prices, see, e.g., Beck (Beck, S., 1993. A Rational Expectations Model of Time Varying Risk Premia in Commodities Futures Markets: Theory and Evidence. International Economic Review 34, 149–168, Beck, S., 2001. Autoregressive Conditional Heteroskedasticity in Commodity Spot Prices. Journal of Applied Econometrics 16, 115–132). In this paper, we propose an alternative functional relationship (from GARCH(1,1) to GARCH(1,1)-AR(m)) between spot price risk and spot prices that is fully supported by the classical rational expectations model, and based on this new representation we are able to provide stronger empirical support for Muth's rational expectation theory.
