Do Geographic Entry Restrictions Increase Car Prices?

Many states allow existing retail vehicle dealerships to challenge the entry of new competitors. Earlier studies found these restrictions resulted in higher vehicle retail prices. However, the studies used average vehicle prices or proxies for average prices and were not able to control for the numerous features and amenities that differentiate vehicles. The previous work was also conducted pri...

Diagonal entry restrictions in minimum rank matrices

Let F be a field, let G be a simple graph on n vertices, and let S (G) be the class of all F -valued symmetric n × n matrices whose nonzero off-diagonal entries occur in exactly the positions corresponding to the edges of G. For each graph G, there is an associated minimum rank class, M R (G) consisting of all matrices A ∈ S (G) with rankA = mr (G), the minimum rank among all matrices in S (G)....

Incorporating Selectional Restrictions into HPSG

This article is concerned with integrating the phenomenon of selectional restrictions in a formal grammar theory. Firstly, the question of treating selectional restrictions purely in the semantic module is discussed, as there are some contextual (or pragmatic) influences, which can repair the ill-formedness of violated selectional restrictions. Secondly, we shed light on the stucture of pragmat...
