Given two linear regression models y1=X1[beta]1+u1 and y2=X2[beta]2+u2 where the response vectors y1 and y2 are unobservable but the sum y=y1+y2 is observable, we study the problem of decomposing y into components and , intended to be close to y1 and y2, respectively. We develop a theory of best...

We experimentally test Dufwenberg and Kirchsteiger's (2004) theory of sequential reciprocity in a sequential prisoner's dilemma and a mini-ultimatum game. Data on behavior and first- and second-order beliefs allow us to classify each subject's behavior as a material best response, a reciprocity...

This monograph is a contribution to the theory of encompassing. It formalizes the idea that a model should be able to explain the result to obtained by other, rival models. From the properties of the encompassing relation established here, it follows that encompassing can be used as a...
