We derive aggregate growth-accounting implications for a two-sector economy with heterogeneous capital subsidies and monopoly power. In this economy, measures of total factor productivity (TFP) growth in terms of quantities (the primal) and real factor prices (the dual) can diverge from each...

Financial institutions often do not charge explicit fees for the services they provide, but are instead compensated by the spread between interest rates on loans and deposits. The lack of explicit fees in lending makes it difficult to measure the output of banks and other financial institutions....

Many people point to information and communications technology (ICT) as the key for understanding the acceleration in productivity in the United States since the mid-1990s. Stories of ICT as a 'general purpose technology' suggest that measured TFP should rise in ICT-using sectors (reflecting...

We construct a measure of aggregate technology change, controlling for imperfect competition, varying utilization of capital and labor, and aggregation effects. On impact, when technology improves, input use falls sharply, and output may fall slightly. With a lag of several years, inputs return...

Many companies on China's stock markets have separate, restricted classes of shares for domestic residents and foreigners. Other than who can own them, these shares are identical, but foreigners pay only about one-quarter the price paid by domestic residents. We show that plausible...

At a macroeconomic level, infrastructure and productivity are positively correlated in the United States and other countries. However, it remains unclear whether this correlation reflects causation, and if so, whether causation runs from infrastructure to productivity, or the reverse. This paper...

We assess links between China and the rest of emerging Asia. Some commentators have argued that China’s apparent devaluation in 1994 may have contributed to the Asian financial crisis. We argue that the devaluation was not economically important: The more-relevant exchange rate was a floating...
