This paper investigates the problem of an ``optimum population'' with respect to the age structure. Within a 3-period OLG model, with endogenous fertility and longevity, the optimal age structure, identified by number-dampened total utilitarianism, is generally failed in the laissez-faire...

According to empirical studies, the life cycle of labor supply volatility exhibits a U-shaped pattern. This may lead to the conclusion that demographic change induces a drop in output volatility. We present an overlapping generations model that replicates the empirically observed pattern and...

Cities and towns are loci of population and production. In 2010, 80.7 percent of the United States population resided in urban areas, and the U.S. Bureau of Economic Analysis reported that in 2011, 90.1 percent of GDP was produced in metropolitan statistical areas (MSAs), emphasizing that urban...

Alike most of the Western world, the Danish fertility rate declined throughout the 20th century simultaneous to economic growth. This development, which conflicts with economic intuition, has been denoted the fertility paradox, and several studies have been devoted to resolve it. The present...

New firm formation is often highly prioritized by local governments, particularly for regions that are declining. Entrepreneurship can play an important role in keeping declining regions vital through job creation. Yet, the way in which new firm formation exerts its influence on employment...

In East Germany a profound demographic change has been taking place that manifests itself in the shrinkage and the aging of the population. One major cause is the drop in the East German fertility rates by about half directly after the reunification of Germany in 1990. In no other countries of...
