A BAYESIAN ALTERNATIVE TO GENERALIZED CROSS ENTROPY SOLUTIONS FOR UNDERDETERMINED ECONOMETRIC MODELS AgEcon
Heckelei, Thomas; Mittelhammer, Ronald C.; Jansson, Torbjorn.
This paper presents a Bayesian alternative to Generalized Maximum Entropy (GME) and Generalized Cross Entropy (GCE) methods for deriving solutions to econometric models represented by underdetermined systems of equations. For certain types of econometric model specifications, the Bayesian approach provides fully equivalent results to GME-GCE techniques. However, in its general form, the proposed Bayesian methodology allows a more direct and straightforwardly interpretable formulation of available prior information and can reduce significantly the computational effort involved in finding solutions. The technique can be adapted to provide solutions in situations characterized by either informative or uninformative prior information.

Applications and Interviews. A Structural Analysis of Two-Sided Simultaneous Search AgEcon
Wolthoff, Ronald P..
Much of the job search literature assumes bilateral meetings between workers and firms. This ignores the frictions that arise when meetings are actually multilateral. I analyze the magnitude of these frictions by presenting an equilibrium job search model with an endogenous number of contacts. Workers contact firms by applying to vacancies, whereas firms contact applicants by interviewing them. Sending applications and interviewing applicants are costly activities but increase the probability to match. In equilibrium, contract dispersion arises and workers spread their applications over the different contract types. Estimation of the model on the Employment Opportunities Pilot Projects data set provides values for the cost of an application, the cost of an...
