How quickly is temporary market inefficiency removed?

I provide evidence on the length of time it takes for arbitrageurs to exploit attractive investment opportunities. A unique data set from the Internet sports betting market allows me to focus on the speed of investor response in an environment that is not affected by the joint hypothesis problem. The market does not instantly converge to an efficient level after mispricing occurs, but the adjustment process is rapid. Arbitrageurs remove many of these opportunities within minutes of them being created and the majority are gone within an hour. Arbitrage opportunities that are more difficult to find last for longer.     

“Third World” Multinationals Revisited

Abstract

The notion of “Third World Multinationals” has always been, at least, slightly misleading, and has now also become obsolete, taking into account the dismantlement of most of the ideological divides between different political and economic blocks since the early 1990s, and the new rules of the games imposed by globalization. Furthermore, new multinationals emerging from China, and also from the former Soviet republics, are demanding a new and more flexible taxonomy. The present paper re-defines “Multinationals from Developing Countries” (MEDCs) and it reviews first, the current literature on multinationals, looking at the key factors which may explain the internationalization process of enterprises coming from outside the traditional, developed, and industrialised world, and also whether they may enjoy specific sources of comparative advantages, different from those ascribed to the old, established multinationals. A statistical appendix provides a brief but comprehensive survey of the current status of MEDCs, pointing out that, at the end of the day, there are roughly only four such enterprises in the usual rankings of the first one hundred multinational corporations, worldwide, and that the prospects of a forthcoming, and enhanced upgrading in the global corporate structure are heavily geared towards Asia. The data would also seem to support the argument that sheer “scale”, as such, of the enterprises does not explain a greater or lower degree of “transnationalization,” a conclusion which, added to that of the greater flexibility provided by the new information technologies, could be goods news for small-and medium-sized enterprises coming from the developing world.     

Pay dispersion and the financial performance of the firm: evidence from Korea

Pay dispersion has been found in prior research to negatively affect both individual and workplace performance. In this study, we examine whether the relationship between horizontal pay dispersion and firm financial performance is curvilinear in nature, with moderate levels of dispersion leading to more positive outcomes than either low or high levels. Using data from a government-sponsored survey of Korean firms, we find support for the hypothesized curvilinear relationship between pay dispersion and firm financial performance. We further find that this curvilinear relationship is moderated by firm and human resource system characteristics. Where the firm had more incumbents in the rank being examined, where pay level was higher, and where there was greater organizational investment in performance evaluation and feedback, the positive slope (within the curvilinear relationship) inverted at a higher level of dispersion.

Towards an operational sustainability criterion

This paper examines the concept of sustainability and its implications for environmental policy analysis. It builds on the premise that present society holds a moral obligation to pass on a world of undiminished life opportunities to members of future generations. Maintaining life opportunities, in turn, can be achieved by maintaining or improving a diverse set of resources and capabilities that support a person's freedom to define and pursue her own conception of the good life. On an operational level, this framework points to the following guideline for environmental policy: Protecting the rights of future generations requires either the conservation of environmental resources or compensatory measures (including the provision of substitute technologies) that ensure the fair and proportionate sharing of net benefits over intergenerational time scales. In this framework, resource depletion is permissible only if (with reasonable certainty) it would generate a Pareto improvement relative to a baseline scenario involving strict resource conservation.     

A Model of Competing Jurisdictions with Locally Polluting Environments and Mobile Populations

In this model we consider a federation consisting oftwo geographically separated Regional states withlocal taxing authority. The residents of thefederation are identical in preferences and haveexplicit tolerance to pollution. Pollution is local innature and is a by-product of production implying amore highly populated region would generate morepollution. Local authorities in the regions can andwill (in the interest of local residents) engage ingame theoretical taxation strategies. The model isused to illustrate that Nash Equilibrium can resultwherein the two regions have different levels ofenvironmental quality. The resulting Nash conditionsimply for instance that residents of the ``cleanregion' will subsidize those in the other region tostay in the more polluted environment (in order foreach to accomplish their preferred consumption andenvironmental quality pair).
