I set out a new method for estimating true (Konüs) PPPs. Household consumption per head deflated by these PPPs answers the question: by how much must the average expenditure per head of poor country A be increased to enable the typical inhabitant of A to enjoy the same utility level as the...

New inventions are good for economic growth, but equally important are improvements in the way we make things - what's known as process innovation. Tim Leunig and Joachim Voth measure the impact of two such innovations - mechanical cotton spinning and the motorcar assembly line - on the world's...

We analyze the effects of Brexit on the UK economy. The most important economic consequence of Brexit would likely be reduced trade with EU countries. We consider an optimistic scenario with relatively small increases in trade barriers between the UK and the EU and a pessimistic scenario with...
