What nutrition label to use in a catering environment? A discrete choice experiment

Worksite and university canteens are increasingly used for daily main meal consumption. Following the use of front-of-pack nutrition labels on pre-packed foods, the provision of easily accessible nutrition information on foods prepared and consumed out of home is a highly topical policy issue with the potential to help consumers making better informed and more healthy food choices when eating out. Information that is presented in a format preferred by the target group is more likely to be used. A sample of 1725 university canteen users participated in a web-based choice experiment designed to identify and understand individual preferences for alternative nutrition labels on canteen meals. Participants valued the presence of nutrition labels on canteen meals and showed a preference for more detailed formats. Ability and motivation to process information as well as socio-demographics explained differences in label preferences. Observed decreasing marginal utility from combinations of two simple label formats as well as from combinations of two detailed formats, signalled information insufficiency versus information overload, respectively. In order to satisfy most canteen users’ information needs, a nutrition label that contains basic Guideline Daily Amount (GDA)-type of numerical information in combination with familiar visual aids like stars and colour codes is proposed to be used in university canteens.     

Managing Economic and Virtual Economic Capital Within Financial Conglomerates

Abstract

In this paper we show how the optimal amount of economic capital can be derived such that it minimizes the economic cost of risk-bearing. The economic cost of risk-bearing takes into account the cost of the economic capital as well as the exposure to residual risk. In addition to the absolute problem of determining the amount of economic capital, we also consider the relative problem of how to establish the allocation of economic capital among subsidiaries. Because subsidiaries are juridical entities, they will also consider the absolute problem of economic capital allocation themselves. In an equilibrium situation, the relative allocation derived by the conglomerate and the absolute allocation derived by the subsidiaries coincide. We show that the diversification benefit that is typically obtained in a conglomerate construction creates a virtual economic capital for subsidiaries within the conglomerate. We show further that the approach we propose to solve the absolute problem of economic capital allocation also can be applied to the problem of optimal portfolio selection, extending the well-known Markowitz approach and providing a tool for management by economic capital.     

Pairs trading

‘Pairs Trading’ is an investment strategy used by many Hedge Funds. Consider two similar stocks which trade at some spread. If the spread widens short the high stock and buy the low stock. As the spread narrows again to some equilibrium value, a profit results. This paper provides an analytical framework for such an investment strategy. We propose a mean-reverting Gaussian Markov chain model for the spread which is observed in Gaussian noise. Predictions from the calibrated model are then compared with subsequent observations of the spread to determine appropriate investment decisions. The methodology has potential applications to generating wealth from any quantities in financial markets which are observed to be out of equilibrium.     

Is backdating executive stock options always costly to shareholders?

We use a binomial model to investigate the cost to shareholders of backdating employee stock option (ESO) grants to award in‐the‐money rather than at‐the‐money options to a manager. When the expected return of the stock underlying an ESO is sufficiently close to the risk‐free rate, a backdating arrangement can always be structured to simultaneously improve shareholders’ wealth and the manager's utility. The smaller the manager's non‐option wealth, personal income tax rate or risk tolerance, the more likely a backdating arrangement can be welfare improving.     

Gathering Information and Exercising Influence: Two Forms of Civic Virtue Organizational Citizenship Behavior

Political behavior at work often is disparaged as self-serving activity that undermines the efficient pursuit of organizational goals. Yet politics has a more benign meaning as well: responsible participation in decision-making processes, keeping informed, and promoting innovative ideas that serve long-term organizational interests. To date, the negative image of organizational politics among managers and scholars has limited research on the positive contributions of responsible political participation, a form of Organizational Citizenship Behavior (OCB) known as civic virtue.This paper draws on political philosophy and organizational research to consider two forms of civic virtue OCB: gathering information and exercising influence. Both are proactive and can have beneficial results for individuals, organizations, and society. Conceptually, the two forms of civic virtue are related. Yet they also are different. Results of a field study of 245 employees and their supervisors provide support for similarities and differences in the two forms of civic virtue. We discuss theoretical and practical implications of our study, and the benefits of continued research on both aspects of civic virtue OCB.An earlier version of this paper was presented at the Society for Industrial and Organizational Psychology, Orlando FL, April 2003, in a symposium entitled “New Perspectives on the Dimensionality of Organizational Citizenship Behavior.” A newer version of this paper was presented at the October 2005 International Meeting of the Association on Employment Practices and Principles (AEPP) in Baltimore, MD.     

An institutional analysis of the US foreign sales corporation

The purpose of this paper is to illustrate how institutional analysis can be applied to the study of an evolving institution—the Foreign Sales Corporation (FSC). The FSC was created by the US government to provide a tax incentive to domestic exporters. It has a checkered history because the European Union views it as an export subsidy. After establishing that the FSC is definitely an institution, Scott’s institutional synthesis is utilized as a conceptual prism to demonstrate how his framework can be utilized to examine complex phenomena. The study also tests a crucial proposition for institutional theory and explores a research question critical to the continuing development of the theory. That question deals with the persistence of the FSC as an institution.     

The scheduling and organization of periodic associative computation: Efficient networks

This paper characterizes the efficient decentralized networks for calculating the associative aggregate of cohorts of data of a fixed size that arrive periodically. Radner (1993) proposed this problem of periodic parallel associative computation as a model of the ongoing information processing and communication by the administrative staff of a large organization. For a simpler model in which the organization processes a single cohort of data – which is equivalent to the periodic model when the agents are paid only when busy – he found that the efficient networks are hierarchical but quite irregular, even though the computation problem and technology are each symmetric. In the periodic model in which managers are paid even when idle, it becomes important to minimize idle time when scheduling managers to processing tasks. Such scheduling appears more difficult when each problem is processed by an irregular hierarchy, which suggest that hierarchies might be more regular in the periodic model. However, we show that in a class of efficient networks for periodic computation that spans the efficiency frontier, the processing of each cohort is similar to the efficient processing of a single cohort, and the overall organizational structure is not even hierarchical.
