This paper examines the effects of specialisation (within-sector clustering) and diversity (between-sector clustering) on business services profitability and location choice. We apply a semiparametric Poisson sorting model allowing for firm-specific effects. We find that for most firms,...

This paper estimates a heterogeneous sorting model for firms, employing a semiparametric Poisson approach. We show that there is an equivalence relation between a locally weighted Logit and Poisson model. We apply our model to estimate firm-specific preferences of business services firms for...

We introduce a sorting model for firms where firm-specific profit coefficients can be identified given information on location choices of firms. It is shown that one may estimate such a model using a semiparametric Poisson approach. We apply this approach by examining the effects of...
