Two innovations in the last century have changed dramatically the cost of communicating and transmitting information: The first is the widespread adoption of telephony; the second is the internet. We study the implications of these changes in ICT for urban structure. We find robust evidence that...

In this paper we derive a microfounded macro New Keynesian model for open economies, be them large or small. We consider habit formation in consumption, sectoral linkages for tradable and non-tradable goods, capital stock investments with variable capital utilization, domestic and foreign...

This paper identifies several distortions which create barriers to entrepreneurship. First, in addition to the innate entry cost, there are entry costs caused by regulation. Second, union wage policies raise the opportunity cost of entrepreneurship. Third, inefficiencies in the transmission of...

Federal and state governments often differ in the capacity to pre-commit to expenditure and tax policy. Whether the implied sequence of public decisions has any efficiency implications is the subject of this paper. We resort to a setting which contrary to most of the literature does not exhibit...

This paper investigates how parametric reform in a pay-as-you-go pension system with a tax benefit link affects retirement and work incentives of prime-age workers. We find that postponed retirement tends to harm incentives of prime-age workers in the presence of a tax benefit link, thereby...

An effective policy scheme to overcome the suboptimal low provision levels of global public goods is developed in this paper. By suggesting a decentralized approach to raise environmental public good provision levels we take account of the lack of a coercive global authority that is able to...

We analyze a simple model of local public good provision in a region comprising two districts, a city and a village. When districts remain autonomous and local public goods have positive spillover effects on the neighboring district, there is underprovision of public goods in both the city and...

In public good provision, privileged groups enjoy the advantage that some of its members find it optimal to supply a positive amount of the public good. However, their inherent asymmetric nature may make the enforcement of cooperative behavior through informal sanctioning harder to accomplish....

We present a model of courtship in which the timing of marriage is affected by the cognitive dissonance between perceived norms and personal aims. We argue that as long as the family has been the main provider of social protection, marriage has been favoured by strongly felt social norms, and...

Politicians are disciplined through the electoral system. But this is often not enough to eliminate political rents. Economists suggest that competition across governments may also help. But intergovernmental competition can take two forms, through tax competition (exit) or yardstick competition...
