Boom Towns and Ghost Countries: Geography, Agglomeration, and Population Mobility - Working Paper 36

Ghost towns dot the West of the United States. These cities boomed for a period and then, for various reasons, fell into a process of decline and have shrunk to a small fraction of their former population. Are there ghost countries—countries that, if there were population mobility, would only have a very small fraction of their current population? This paper carries out four empirical illustrations of the potential magnitude of the "ghost country" problem by showing that the "desired population" of any given geographic region varies substantially.
