To find the optimal size of a country and therefore the optimalnumber we need to look at the costs and benefits of making acountry larger
Benefits - fixed cost such as the provision of public goods likedefense are shared between more individualsCosts - the country will be more heterogeneous so theprovision of a public good may be further on average fromeach individuals ideal

The Dissolution of States
Well defined ethnolinguistic and cultural differences exist inmany of the examples of the dissolution of states - tribes
Differences in preferences between members of the two tribesmay be more important than any heterogeneity of preferenceswithin a tribe.
Redistributional conflict between tribes may explaindissolution of states
