Although there is evidence that CO2-efficiency enhancing innovations in one country diffuse into other countries to contribute to the goals of climate change mitigation, very little is known about the conditions under which such international spillovers are most likely to take place. Our...

We analyze the spread of policies dealing with international trafficking in human beings. Arguing that countries are unlikely to make independent choices, we identify pressure, externalities and learning or emulation as plausible diffusion mechanisms for spatial dependence in anti-trafficking...

We analyze spatial spillover effects in international tourism as a consequence of transnational terrorist attacks. Specifically, we hypothesize that attacks executed in Islamic countries on citizens from Western countries will generate spatial spillovers of three kinds. Firstly, tourism from the...
