ORGANIZATIONAL STRUCTURE AND THE DIVERSIFICATION DISCOUNT: EVIDENCE FROM COMMERCIAL BANKING*

We provide evidence on organizational structure and performance at bank holding companies (BHC's). First, we show that a BHC's member banks benefit from access to internal capital markets. Second, we ask if these benefits are best realized within loosely structured, decentralized organizations or more consolidated, centralized firms. We find that BHC's with many subsidiaries are less profitable and have lower q ratios than similar BHC's with fewer subsidiaries. However, because we study multi‐unit firms in a single industry, our results suggest that the diversification discount reported in the corporate finance literature reflects not only industry diversification, but also organizational structure.     

Monetary Policy Response to Oil Price Shocks

How should monetary authorities react to an oil price shock? This paper shows that in a noncompetitive economy, policies that perfectly stabilize prices entail large welfare costs, hence explaining the reluctance of policymakers to enforce them. The policy trade‐off is nontrivial because oil (energy) is an input to both production and consumption. As welfare‐maximizing policies are hard to implement and communicate, I derive a simple interest rate rule that depends only on observables but mimics the optimal plan in all dimensions. The optimal rule is hard on core inflation but accommodates oil price changes.     

The Reversal of Large Stock-Price Decreases

Extremely large negative 10-day rates of return are followed on average by larger-than-expected positive rates of return over following days. This price adjustment lasts approximately 2 days and is observed in a sample of firms that is largely devoid of methodological problems that might explain the reversal phenomenon. While perhaps not representing abnormal profit opportunities, these reversals present a puzzle as to the length of the price adjustment period. Such a slow recovery is inconsistent with the notion that market prices quickly reflect relevant information.     

Public Interest, Ethics, and the Balanced Scorecard: Implications for the Accounting Profession

The accounting profession bos been grappling with the issue of public interest responsibility for a number of years. The aim of this paper is to examine how a balanced scorecard (BSC) model can be used by the accounting profession to more effectively incorporate a public interest responsibility in its strategic framework. By using a BSC model, the paper provides an integrated framework for translating strategic values into a comprehensive set of objectives, performance measures and improvement actions .     

Transnational Organizing in Agrarian Central America: Histories, Challenges, Prospects

Central America was one of the principal regions where transnational peasant organizing emerged and from which it spread in the late 1980s and early 1990s. Yet by the late 1990s the seemingly powerful transnational peasant coalitions were in disarray. Their successors have had only a modest impact since 2001. The article points to two main sources of weakness in Central America's transnational peasant coalitions: first, a variety of intra-organizational problems, including political differences, disputes over resources, over-funding by cooperation agencies, and an emphasis on networking activity, rather than concrete gains, as a measure of success; and second, an external political, economic and demographic environment that has become increasingly unfavourable. Elements of the latter include the long-term declines in maize and coffee prices, only recently reversed in 2006; the declining importance of agriculture and the imposition of a new economic model centred around industrial and financial activities; and the rapidly growing levels of out-migration and of dependence of those remaining in the countryside on family remittances and non-agricultural activities. The article concludes not with definitive arguments, but rather with a series of questions about what might constitute effective strategies for transnational peasant organizing in an extremely problematic context, such as contemporary Central America.     

Asymptotics of the price oscillations of a European call option in a tree model

It is well known that the price of a European vanilla option computed in a binomial tree model converges toward the Black-Scholes price when the time step tends to zero. Moreover, it has been observed that this convergence is of order 1/ n in usual models and that it is oscillatory. In this paper, we compute this oscillatory behavior using asymptotics of Laplace integrals, giving explicitly the first terms of the asymptotics. This allows us to show that there is no asymptotic expansion in the usual sense, but that the rate of convergence is indeed of order 1/ n in the case of usual binomial models since the second term (in     ) vanishes. The next term is of type   C ₂( n )/ n   , with   C ₂( n )  some explicit bounded function of n that has no limit when n tends to infinity.     

Comparable Axiomatizations of Two Allocation Rules for Cooperative Games with Transferable Utility and Their Subclass of Data Games

The axiom of balanced collective contributions is introduced as a collective variant of the axiom of balanced contributions proposed by Myerson. It requires the identical average impact of the withdrawal of any agent from a game on the remaining population. It turns out that the axiom of balanced collective contributions and the classical axiom of efficiency characterize the equal allocation of nonseparable costs, an allocation rule that is extensively used in cost allocation problems and in accounting. In particular, the equal allocation of nonseparable costs coincides with the nucleolus on the class of data games within the European REACH legislation. While our result does not hold on data games, extra axioms enable provision of comparable characterizations of the equal allocation of nonseparable costs and the Shapley value on this class of games.
