Philipp Ketz*

Sometimes economic theory implies a priori restrictions on certain model parameters. For example, the demand for an ordinary good will decrease given an increase in price, i.e., the coefficient on price, or the effect of price on demand, is a priori known to be negative. Another primary example is given by random coefficients models, where variance parameters are a priori known to be non-negative. When “taking the model to the data”, economists are not only ...
