Time-to plan lags for commercial construction projects
We use a large project-level dataset to estimate the length of the planning period for commercial construction projects in the United States. We find that these time-to-plan lags are long, averaging about 17 months when we aggregate the projects without regard to size and more than 28 months when we weight the projects by their construction cost. The full distribution of time-to-plan lags is very wide, and we relate this variation to the characteristics of the project and its location. In addition, we show that time-to-plan lags lengthened by 3 to 4 months, on average, over our sample period ...

Is the information technology revolution over?
Given the slowdown in labor productivity growth in the mid-2000s, some have argued that the boost to labor productivity from IT may have run its course. This paper contributes three types of evidence to this debate. First, we show that since 2004, IT has continued to make a significant contribution to labor productivity growth in the United States, though it is no longer providing the boost it did during the productivity resurgence from 1995 to 2004. Second, we present evidence that semiconductor technology, a key ingredient of the IT revolution, has continued to advance at a rapid pace and ...

How Fast are Semiconductor Prices Falling?
The Producer Price Index (PPI) for the United States suggests that semiconductor prices have barely been falling in recent years, a dramatic contrast to the rapid declines reported from the mid-1980s to the early 2000s. This slowdown in the rate of decline is puzzling in light of evidence that the performance of microprocessor units (MPUs) has continued to improve at a rapid pace. Over the course of the 2000s, the MPU prices posted by Intel, the dominant producer of MPUs, became much stickier over the chips' life cycle. As a result of this change, we argue that the matched-model methodology ...

Own-Account IT Equipment Investment
This note considers a puzzle: why has information technology (IT) equipment investment in the National income and Product Accounts (NIPAs) been so weak since 2007 at the same time that financial reports indicate massive increases in capital expenditures by IT service companies?

The equilibrium real policy rate through the lens of standard growth models
The long-run equilibrium real policy rate is a key concept in monetary economics and an important input into monetary policy decision-making. It has gained particular prominence lately as the Federal Reserve continues to normalize monetary policy. In this study, we assess the evolution, current level, and prospective values of this equilibrium rate within the framework of standard growth models. Our analysis considers as a baseline the single-sector Solow model, but it places more emphasis on the multi-sector neoclassical growth model, which better fits the data over the past three decades. ...

The evolution of household income volatility
Using data from the PSID, we find that household income has become noticeably more volatile during the past thirty years. We estimate that the standard deviation of percent changes in household income rose one-fourth between the early 1970s and early 2000s. This widening in the distribution of percent changes is concentrated in the tails of the distribution, and especially in the lower tail: Changes between the 25th and 75th percentiles are almost the same size now as thirty years ago, but changes at the 10th percentile look substantially more negative. The boost in volatility occurred ...
