A note on Measurement Error and Euler Equations: an Alternative to Log-Linear Approximations
Ventura, Eva - EconWPA - 2003
Empirical research based on panel data has to pay special attention to measurement errors. Utility maximization often yields nonlinear decision rules in which measurement errors enter in a multiplicative way. The usual strategy to deal with them consists of taking log-linear approximations of...

Access Charges in the Presence of Call Externalities
Berger, Ulrich - EconWPA - 2004
We introduce call externalities in the standard model of network competition with termination-based price discrimination, and employ a simple graphical analysis to study the outcome of competition. In contrast to recent results in the literature, we find that even under linear pricing, access...
