This paper examines three questions motivated by previous research on semiconductors and productivity growth: Why did … semiconductor prices fall so rapidly in the second half of the 1990s, why has the rate of price decline slowed since 2001, and to … what extent are these price swings associated with changes in the rate of advance in semiconductor technology? We show that …

Sharp declines in semiconductor prices are largely responsible for observed declines in computer prices. Although … communications equipment also has a large semiconductor content, communications equipment prices do not fall nearly as fast as …

semiconductor devices. These data may be used to construct indexes under different assumptions from those used in indexes that are …

At a macroeconomic level, infrastructure and productivity are positively correlated in the United States and other … infrastructure to productivity, or the reverse. This paper focuses on roads, and finds that vehicle-intensive industries benefit … disproportionately from road-building: when road growth changes, productivity growth changes more in industries that are more vehicle …

countries. The paper begins by surveying earlier estimates of relative productivity and unit labor cost levels and evaluating … productivity translated into dollars at purchasing power parity exchange rates. These estimates are compared with results obtained …

Productivity rises in booms and falls in recessions. There are four main explanations for procyclical productivity: (i … are particularly important in explaining procyclical productivity. We argue that the reallocation effects that we identify …

Explanations of procyclical productivity playa key role in a variety of business-cycle models. Most of these models … aggregate productivity changes into several terms, each of which has an economic interpretation. However, many of these tenus …
