This paper examines whether patenting increases the private incentives to innovate in manufacturing. To study this issue, we build a model in which the value of an innovation depends both on the type of innovation implemented (product, process) and on the existence of a patent protection or not....

The unidimensional unfolding model proposed by Coombs (1964) is a tool for scaling preference data. Here we consider the special case where the sets of subjects and objects are identical. We get an unidimensional solution of our problem only if the data satisfy a welldefined structure. Therefore...

Structural decomposition techniques are used to break down the changes in one variable into the changes in its determinants. Typically, these determinants are assumed to be independent. Using the decomposition of value added growth as a prototype example, this paper examines the phenomenon that...

Applications of random utility models to scanner data have been widely presented in marketing for the last 20 years. One particular problem with these applications is that they have ignored possible correlations between the independent variables in the deterministic component of utility (price,...

We analyze households' joint investment decisions for financial wealth and homes. We use a bivariate censored regression model with endogenous switching. Fixed costs or transaction costs are captured by an unobserved nonzero censoring threshold. The model allows for spill-over effects of a...
