While stock market expectations are among the most important primitives of portfolio choice models, their measurement … can be used as an indicator of the degree to which economic models of portfolio choice provide an ade- quate …

In past years, the most common approaches for deriving early-warning models belong to the family of binary …. The evidence in this paper shows that early-warning models should not be used in this traditional way, as the optimization …

Having estimated 84 nested and non-nested count data models, we found that the hurdle models are … preferred for taking into account the presence of excess zeros.
