A Bayesian belief network is adopted to structure and manage an entry
decision problem, where a potential entrant has to evaluate the profit
ability of a given market, depending on an established firm's unknown
and unobservable multidimensional type. A multiperiod multisignal mode
l is defined to take account of strategic interaction processes betwee
n the incumbent and the potential competitor. Since significant theore
tical and computational issues prevent us from finding optimal strateg
ies, a myopic policy is discussed that leads to a reasonable outcome.
An application example of the proposed solution procedure is also pres
ented.
