This paper analyzes the implications of rent control as applied to dwellings located in mobile home parks. This form of regulation differs from apartment rent control in that: it is applied selectively to a small portion of the housing stock, and; it regulates the site rents paid to the park owner, not the selling prices of mobile homes. We present a detailed case study of the effects of this institution in three mobile home parks in different cities and regions in California, documenting the capitalization of regulatory rules into the selling prices of housing, and raising questions about the legality as well as the efficacy of the institution.

Demographic analysis clarifies political issues in the collapse of Yugoslavia. In most regions, 1961-1991, ethnic diversity (estimated by informational entropy) increased and segregation (estimated by Theil’s H) decreased. In a few regions there was a reversal in 1991 as migration flows or presentations of self perhaps changed in anticipation of war. The analysis strengthens refutations of the view that long standing ethnic hatreds were the root cause of the Yugoslav collapse and supports analyses that attribute collapse to general economic crisis, economic competition between regions, and failures at the peak of government.
