The global financial crisis and the subsequent uneven recovery have underscored the need for Africa's resilience to output and other shocks originated in the rest of the world. A comparison of two regional economic communities - the East African Community (EAC) and the Southern Africa Customs...

We use Swedish register data to compare the employment and income of immigrants who intermarry natives versus those of immigrants who intramarry other immigrants in Sweden. We conduct the same analyses on three subsamples: labour migrants, refugees and family migrants. We find that intermarried...

This paper studies the social desirability of agglomeration and the efficiency arguments for policy intervention in a simple, analytically solvable 'new economic geography' model with two trade integrating regions. The location pattern emerging as market equilibrium is bubbleshapedʺ, i.e. it...
