Estimation risk is known to have a huge impact on mean/variance (MV) optimized portfolios,which is one of the primary reasons to make standard Markowitz optimization unfeasible inpractice. Several approaches to incorporate estimation risk into portfolio selection are suggestedin the earlier...

This paper introduces an expected value estimator with expert knowledge to the robust estimation of sovereign rating transitions which are characterised by few observations. Ourestimates of default premia within Mexican, Colombian and Brazilian Eurobond yield spreads provide a better fit than...

Bayesian Model Averaging (BMA) has recently been discussed in the financial literature as an effective way to account for model uncertainty. In this paper we compare BMA to a new model uncertainty framework introduced by Yang (2004), called Aggregate Forecasting Through Exponential Reweighting,...

We measure labor market frictions using a strategy that bridges design-based and structuralapproaches: estimating an equilibrium search model using reduced-form minimum wageelasticities identified from border discontinuities and fitted with Bayesian and LIML methods.We begin by providing the...
