According to conventional wisdom, a currency area benefits from internal labour mobility. If independent stabilisation policies are unavailable, the argument goes, factor mobility helps regions respond to shocks. Reasonable as it sounds, few attempts have been made to test this intuition in state-of-the-art macroeconomic models. In a recent Staff Working Paper (also available here), we build a DSGE model of a currency area with internal migration to go through the maths. So does the old intuition hold up? The short answer, we think, is yes. Internal labour mobility eases the burden on monetary policy by reducing regional labour markets imbalances. But policymakers can improve welfare by putting greater weight on unemployment. Effectively, interregional migration justifies a somewhat higher ‘lambda’.
Apocalypse Now is widely regarded as a masterpiece of the new Hollywood era. Director Francis Ford Coppola displayed audacious vision and a willingness to take risks. But we don’t just mean artistic risk. Mr Coppola gambled financially too: he staked his Napa Valley house and vineyard on the film, pledging it order to get the $32 million in loans necessary to keep the production on the road. While his movie was exceptional, there is nothing unusual about Mr Coppola’s financial strategy. Small business owners worldwide use their personal assets, and often their house, to back loans to their firms: in a new paper, we use microdata for several thousand firms to show how important this can be for UK investment.
