Location choice models reveal zero-sum vs. positive-sum economic impact.
Location choice models like conditional logit and Poisson give the same results for coefficients when factors are not individual-specific. However, they differ in their predictions. Conditional logit suggests a win-lose situation between regions, while Poisson implies a win-win scenario. A nested logit model with an outside option can represent all cases between these extremes. The elasticities of conditional logit and Poisson mark the boundaries in this research.
