Learning versus Diversification in Project Choice

Subramanian, Narayanan; Menon, Nidhiya - EconWPA - 2004

We study the issue of project choice when a risk-averse agent must choose whether to invest in two projects of the same … speed of learning (ii) the type-specific risk and (iii) his risk- aversion and investment horizon. We show that, contrary to … intuition, an increase in type-specific risk may lead to a decrease in diversification. Our theory is applicable to occupational …

INTERNATIONAL EXPANSION THROUGH SEQUENTIAL INVESTMENT: THE EFFECTS OF NATIONAL CULTURE ON BUYOUTS AND DISSOLUTIONS IN BIOTECHNOLOGY PARTNERSHIPS

FOLTA, TIMOTHY B.; FERRIER, WALTER J. - EconWPA - 1997

This study examines the role of national culture on an issue which is central to competitive strategy: whether to maintain flexibility or commit to a strategic direction. We consider that equity investments in foreign partners may be initiated as the first step in a sequential acquisition...

Learning in Different Social Contests

Novarese, Marco - EconWPA - 2004

This paper aims at analysing the effects of learning on the individual behaviour in an experiment that requires cooperation and coordination within teams. Using artificial agents, different social contests are created, as training environments. The results confirm previous findings (on the...

CONSUMER SEARCH: NOT ENOUGH OR TOO MUCH?

Zwick, Rami; Rapoport, Amnon; Lo, Alison King Chung; … - EconWPA - 2001

We study search behavior in a generalized "secretary problem" environment in which consumers search sequentially for the best alternative from a known and finite set of multi-attribute alternatives. In contrast to most previous studies, we make no distributional assumptions about the quality of...

Istituzioni e mercato del lavoro nel Mezzogiorno d'Italia: un'analisi dinamica

Scarlato, Margherita; Cenci, Marisa - EconWPA - 2004

In this paper a stochastic model is used to analyse the matching process between skills demand and supply in a segmented labor market. We find the steady state solution of the dynamic system and we address the issue of the necessary conditions for the existence of a steady state and for the...

SEARCH, Variable Sample Size, A Computational Solution

Cosme, Pedro - EconWPA - 1997

Morgan (1983) guaranteed that VSS dominated both FSS and SSR. But it is difficult to calculate the optimal sample size and the optimal reservation price both without recall and with full recall. As VSS without recall is a simplification of VSS with full recall, we will present on appendix a VB30...

Scientific Revolution. A Farewell to EconWPA.

Harin, Alexander - EconWPA - 2005

A revolution in economics. Is it possible? Is its concept a transition from ideal to real economics? The way to the transition may be a new aspect of uncertainty. Problems, which can be solved, research fields, which can be augmented or created, and fields of applications in practical economy...
