We analyse cross-country trends in several aspects of technological progress during 1980–2011 by examining the US patent citations data. Our estimation results on patent quality and citation lags relative to the US reveal the following. The emerging Asian economies of Korea, Taiwan and China have achieved substantial catch-up. In the case of Korea and Taiwan, progress has been made in both patent quality and citation lags. China has achieved improvement in patent quality but not in citation lag. In contrast, advanced economies of Europe and Japan have displayed steady decline in patent quality, while the US has strengthened its position.

This Time Is Different: The Microeconomic Consequences of the Great Recession
From an economic point of view, the period since the recession that began in 2008 has been quite unlike any other period since at least the Second World War, including the periods after the recessions of the early 1980s and early 1990s. Indeed, the slowdown has lasted for longer, and its effects on the public finances, on household incomes and on productivity have been more marked even than was the case in the 1930s. This time really does seem to be different.
