This paper focuses on the estimation of an approximated function and its derivatives. Let us assume that the data-generating process can be described by a family of regression models null, where a is a multi-index of differentiation such that D_αnull(x_i) is the αth derivative of null(<italic>x</italic>) with...

The object of this paper is to report, for a simple testing problem of a unit root hypothesis, some experience regarding the numerical problems involved by using a Bayesian encompassing test, i.e., a Bayesian procedure that treats the null and the alternative hypotheses as different models, the...

We propose a model of discrimination in the market for mortgages. The model explains accepted loan applications and determines loan sizes and interest rates simultaneously. A competitive, and a discriminating monopoly version of the model are proposed. Offered interest rates and loan sizes are a...
