This paper investigates what mey be learned about treatment effects when it is assumed that responses functions are monotone, semi- monotone, or concave-monotone.

Extremum estimation is typically an ad hoc semi-parametric estimation procedure which is only justified on the basis of the asymptotic properties of the estimators. For a fixed finite data set, consider a large number of investigations using different extremum estimators to estimate the same...

We investigate an overlapping generations monetary economy in which agents'expectations depend upon backward looking predictors of the future price level.

The objective of this paper is to determine how finite dimensional parameters can be efficiently estimated for an important class of economic models.
