Bueno de Mesquita's 'selectorate' theory fits the limited/open access distinction: small selectorates (e.g., a Politburo) lead states to distribute private goods, while large selectorates (all adult citizens) lead to public goods; but his theory takes the state's monopoly on violence and the selectorate size as given, whereas Weingast argues you must explain how states form by how they solve the problem of violence.
