A theory of legal presumptions

This article analyzes how legal presumptions can mediate betweencostly litigation and ex ante incentives. We augment a moralhazard model with a redistributional litigation game in whicha presumption parameterizes how a court 'weighs' evidence offeredby the opposing sides. Strong prodefendant presumptions forecloselawsuits altogether, but also engender shirking. Strong proplaintiffpresumptions have the opposite effects. Moderate presumptionsgive rise to equilibria in which both shirking and suit occurprobabilisitically. The socially optimal presumption tradesoff agency costs against litigation costs, and could be eitherstrong or moderate, depending on the social importance of effort,the costs of filing suit, and the comparative advantage thatdiligent agents have over their shirking counterparts in mountinga defense. We posit three applications of our model: the litigationrate effects of the 1995 Private Securities Litigation ReformAct, the business judgment rule in corporations law, and fiduciaryduties in financially distressed firms.     

A methodology for managing risk in electronic transactions over the Internet

The explosive growth of the Internet has made possible an economic transformation in which commerce will become largely electronic. In this vision, the medium of communication and negotiation becomes a distributed network of computers equipped with robust, secure and trusted “cash” mechanisms. It is thus of paramount importance to design mechanisms that will ensure timely and reliable transactions in cyberspace. In this paper we present a methodology for quantitatively managing the risk and cost of executing transactions in a distributed network environment by exploiting an analogy with modern financial portfolio theory. We illustrate the methodology with several concrete examples under different pricing schemes, as well as with empirical measurements of Internet traffic. This revised version was published online in June 2006 with corrections to the Cover Date.     

When eWOM becomes cynical

Nowadays, it is common practice for corporations to communicate with consumers through social network sites (SNSs), such as YouTube, which allow consumers to share and comment on companies’ sponsored videos communicating their marketing campaigns. The authors conducted a qualitative assessment of posts written on the official YouTube site of Coca Cola, where the brand asks consumers to join in a brigade against obesity. Results extend the current knowledge about consumers’ negative electronic word of mouth (eWOM), identifying three forms of cynical consumer communication styles in response to corporate campaigns on SNSs: skeptical, passive‐aggressive and warrior eWOM. Managerial implications, limitations and some avenues for future research are indicated.     

Triangular Relations in Public Service Economics

This paper critically re-examines the restructuring of public services. Four main decision-making phases are identified: the public oversight to be guaranteed to socially sensitive economic activities; the ways of financing them; the economic organisation of the industry; and the production decisions. By focusing on organisation, the paper reinterprets the market structure in public service industries on the basis of the interactions among three main players: users/citizens, the government and the service supplier. It argues that the issue of public versus private ownership has been overemphasised, and that an effective increase in efficiency can be obtained by introducing appropriate incentives for both public and business players. Instead of using a single policy instrument, namely privatisation, public action ought to be informed by an array of organisational solutions.     

Participation in Workplace Pension Schemes and the Effect of Provision: Evidence from the United Kingdom*

This study investigates the effect of public policies enforcing workplace pension plan provision on participation rates. Using British data covering almost two decades (1992–2009), I identify the potential opt‐in rate among private sector workers who have not been offered a workplace pension plan, had they been offered the opportunity to join such a saving scheme. I find that universal provision of workplace pension schemes alone could generate a major impact on pension coverage.     

Dynamics of currency crises with asset market frictions

This paper presents a dynamic model of currency crises with frictions. By construction, a speculative attack is not an instantaneous event but takes a little time to deplete the country's reserves and, in the event of an attack, agents are uncertain about whether they will be able to act before the devaluation comes. The currency will be overvalued (‘ripe for attack’) for a long time before an attack takes place. A discrete and sizable devaluation will occur. Small changes in fundamentals may trigger an attack. The model brings insights about the dynamics of currency crises and the effects of some key policy variables.
