The Impact of Volatility on Firms Holding Growth Options

“Abuses of real option valuation were partly behind the ramping and subsequent deramping of the 2000 internet techno bubble. No one ever got to eat the free lunch these real option 'theorists' promised. No one ever will; no one ever could.” (Mayor 2001, 53) Growth options contribute to over 95% of the market value of Internet stocks such as Amazon.com, America Online, and eBay. Finance theory often promotes market volatility as being desirable for investors holding financial options. Is volatility also desirable for firms holding growth options? While many argue that it is, this paper presents a simple example illustrating that increasing volatility can destroy growth option value, especially for firms holding “quality” growth options.     

Keynesian Inefficiency and Optimal Policy: A New Monetarist Approach

A simple model of monetary/labor search is constructed to study Keynesian indeterminacy and optimal policy. In the model, economic agents have trouble splitting the surplus from exchange appropriately, and we consider monetary and fiscal policies that correct this Keynesian inefficiency. A Taylor rule neither implies determinacy, nor does it support an efficient outcome. An optimal policy yields an efficient and determinate allocation of resources, but equilibrium policy actions, wages, and prices are indeterminate at the optimum.     

Low Income Dynamics in 1990s Britain

This paper analyses low income dynamics in Britain using the first four waves of the British Household Panel Survey. There is much low income turnover: although there is a small group of people who are persistently poor, more striking is the relatively large number of low income escapers and entrants from one year to the next. Simulations using estimated low income exit and re-entry rates demonstrate the importance of repeated low income spells for explaining a person's experience of low income over a given period. We also document the characteristics of low income stayers, escapers and entrants.     

Further Evidence on Nontrading-Period Information Release*

Abstract. Using a sample of 856 management earnings forecasts, we provide evidence that managers release larger shock-earnings forecasts in nontrading periods. Our results do not depend on whether the magnitude of the shock is measured exogenously (unexpected accounting earnings) or endogenously (security market reaction). The timing effects are more pronounced for less-precise (i.e., open-interval and closed-interval) forecasts. Also, we provide evidence of an overnight reaction to closed-period management forecast releases. Our results are consistent with explanations for voluntary disclosure that rely on a precommitted policy of information asymmetry reduction (see Diamond 1985; King, Pownall, and Waymire 1990). These explanations lead to predictions of strategic timing of greater shocks in the nontrading period in order to provide the less-informed with a period for information evaluation. Résumé. À partir d'un échantillon de 856 prévisions de bénéfices publiées par la direction de diverses entreprises, les auteurs démontrent que les prévisions publiées par les gestionnaires en période où les titres ne sont pas négociés ont davantage d'impact. Les résultats qu'ils obtiennent ne dépendent pas du caractère exogène (bénéfices comptables inattendus) ou endogène (réaction du marché des valeurs mobilières) de la mesure de l'impact. L'effet du choix du moment est plus prononcé pour les prévisions moins précises (c'est-à-dire à intervalle ouvert et à intervalle fermé). Les auteurs démontrent aussi qu'il se produit une réaction à la publication de prévisions par la direction en période de fermeture, dans les vingt-quatre heures qui suivent la publication. Les résultats de l'étude sont conformes au principe de la présentation facultative d'information dont l'explication repose sur une politique, préalablement adoptée, de réduction de l'asymétrie de l'information (voir Diamond, 1985; King, Pownall et Waymire, 1990). Cette explication mène à des prédictions voulant que l'on choisisse, à des fins stratégiques, les périodes de non-négociation des titres pour publier les prévisions de bénéfices dont l'impact est plus grand, de manière à laisser aux investisseurs moins bien informés un certain laps de temps pour évaluer l'information.
