In a recent paper, Homburg and Richter have argued that with free mobility of labor within a common labor market there is a need to harmonize and even consolidate pay-as-you-go financed national public pension systems to reach an efficient allocation of labor. We show that with free and...

The paper shows that adding social security based on a pay-as-you-go principle (PAYG) prevents countries from successfully harmonizing their individual social security systems. As claimed in the paper, the PAYG systems are extremely complicated to harmonize when the labour force is mobile among...

The EU Single Market remains fragmented by complex and heterogeneous rules at the EU and national levels affecting trade, capital, including foreign direct investment, and labour mobility. Further development of the Single Market and removing barriers to external trade would bring substantial...

Aging changes the political power in a democracy in favor of the elder generations. Consequently, the retirees can extend the pay-as-you-go financed pensions. Under free labor mobility like within the EU, the success of gerontocracy, nevertheless, is restricted by migration of the young...

We present a model of crime where two municipalities exist within a metropolitan statistical area (MSA). Consistent with the literature, local law enforcement has a crime reduction effect and a crime diversion effect. The former confers a spillover benefit to the other municipality, while the...
