Is High Productivity Growth Returning?
Productivity growth has shown a notable pickup since the fourth quarter of 2019, and some commentators cite artificial intelligence and other factors as reasons why technological progress can sustain this faster pace. Motivated by this consideration, we use a model designed to detect trend shifts to examine the behavior of productivity growth in the postwar period. The model allows for shifts between high- and low-growth productivity regimes and estimates the probability of being in one regime or the other. We find that recent data provide tentative support for a higher trend growth rate, ...

Macroeconomic implications of changes in micro volatility
We review evidence on the Great Moderation in conjunction with evidence about volatility trends at the micro level. We combine the two types of evidence to develop a tentative story for important components of the aggregate volatility decline and its consequences. The key ingredients of the story are declines in firm-level volatility and aggregate volatility ? most dramatically in the durable goods sector ? but the absence of a decline in the volatility of household consumption and individual earnings. Our explanation for volatility reduction stresses improved supply chain management, ...

Tracking the new economy: using growth theory to detect changes in trend productivity
The acceleration of productivity since 1995 has prompted a debate over whether the economy's underlying growth rate will remain high. In this paper, we draw on growth theory to identify variables other than productivity - namely consumption and labor compensation - to help estimate trend productivity growth. We treat that trend as a common factor with two "regimes" high-growth and low-growth. Our analysis picks up striking evidence of a switch in the mid-1990s to a higher long-term growth regime, as well as a switch in the early 1970s in the other direction. In addition, we find that ...

The Impact of Credit Risk Mispricing on Mortgage Lending during the Subprime Boom
We provide new evidence that credit supply shifts contributed to the U.S. subprime mortgage boom and bust. We collect original data on both government and private mortgage insurance premiums from 1999-2016, and document that prior to 2008, premiums did not vary across loans with widely different observable characteristics that we show were predictors of default risk. Then, using a set of post-crisis insurance premiums to fit a model of default behavior, and allowing for time-varying expectations about house price appreciation, we quantify the mispricing of default risk in premiums prior to ...

Explaining the gap between new home sales and inventories
For much of the last four decades, the stock of unsold new homes has tracked sales very closely. Since 1995, however, inventories have fallen far behind rapidly advancing sales. What accounts for the change? Market trends have both reduced the need for inventories and slowed the response of inventories to shifts in demand. At the same time, the long current expansion has strained the resources of the building industry, creating supply shortages and raising costs.

Tracking productivity in real time
Because volatile short-term movements in productivity growth obscure the underlying trend, shifts in this trend may go unrecognized for years - a lag that can lead to policy mistakes and hence economic instability. This study develops a model for tracking productivity that brings in additional variables to help reveal the trend. The model's success is evident in its ability to detect changes in trend productivity within a year or two of their occurrence. Currently, the model indicates that the underlying trend remains strong despite recent weak productivity data.

Has inventory volatility returned? A look at the current cycle
The massive liquidation of inventories during the 2001 recession contrasts sharply with the more moderate inventory movements observed in recent decades. While the rundown might be seen as evidence that firms are not managing their inventories as effectively as some economists have claimed, a careful analysis of inventory behavior in 2001 suggests that during much of the recession, firms were successfully regulating their inventories to avoid a large buildup of excess stock.

Productivity swings and housing prices
The housing boom and bust of the last decade, often attributed to "bubbles" and credit market irregularities, may owe much to shifts in economic fundamentals. A resurgence in productivity that began in the mid-1990s contributed to a sense of optimism about future income that likely encouraged many consumers to pay high prices for housing. The optimism continued until 2007, when accumulating evidence of a slowdown in productivity helped dash expectations of further income growth and stifle the boom in residential real estate.>
