Need for Speed: Quality of Innovations and the Allocation of Inventors
This paper studies how the speed-quality tradeoff in innovation interacts with firm dynamics, concentration, and economic growth. Empirically, we document long-run trends in the increasing speed of innovation alongside declining quality at large firms. Leveraging variation from an exogenous policy change, we document the existence of the speed-quality tradeoff both at the firm and aggregate level. We develop an endogenous growth model that incorporates the speed-quality tradeoff and show that allocating less labor towards speed increases growth, particularly in the presence of private ...

Brand Reallocation and Market Concentration
We study the interaction of customer capital and productivity through brand reallocation across firms. We develop a firm dynamics model with brands as transferable customer capital, heterogeneous firm productivity, and variable markups. We study the matching process between transferable brand capital and core productivity, which can be inefficient with significant welfare implications. We link USPTO trademark data with Nielsen sales data to study the prevalence of brand reallocation and the response of sales and prices to reallocation. Quantitatively, brand reallocation reduces welfare. ...

The R&D Puzzle in U.S. Manufacturing Productivity Growth
In a previous post, we provided evidence for a broad-based slowdown in productivity growth across industries and firms in the U.S. manufacturing sector starting in 2010. Since firms’ investment in research and development (R&D) for new technologies constitutes a central driver of productivity growth, in this post we ask if the observed slowdown in productivity may be due to a decline in R&D. We find that “R&D intensity” has been increasing at both the firm and industry level, even as productivity growth declines. This points to a decline in the effectiveness of R&D in generating ...

A New Indicator of Labor Market Tightness for Predicting Wage Inflation
A key question in economic policy is how labor market tightness affects wage inflation and ultimately prices. In this post, we highlight the importance of two measures of tightness in determining wage growth: the quits rate, and vacancies per searcher (V/S)—where searchers include both employed and non-employed job seekers. Amongst a broad set of indicators, we find that these two measures are independently the most strongly correlated with wage inflation. We construct a new index, called the Heise-Pearce-Weber (HPW) Tightness Index, which is a composite of quits and vacancies per searcher, ...

Wage Growth and Labor Market Tightness
Good measures of labor market tightness are essential to predict wage inflation and to calibrate monetary policy. This paper highlights the importance of two measures of labor market tightness in determining wage growth: the quits rate, and vacancies per effective searcher (V/ES)—where searchers include both employed and non-employed job seekers. Amongst a broad set of indicators of labor market tightness, we find that these two measures are independently the most strongly correlated with wage inflation and also predict wage growth well in out-of-sample forecasting exercises. Conversely, ...

The Mysterious Slowdown in U.S. Manufacturing Productivity
Throughout the twentieth century, steady technological and organizational innovations, along with the accumulation of productive capital, increased labor productivity at a steady rate of around 2 percent per year. However, the past two decades have witnessed a slowdown in labor productivity, measured as value added per hour worked. This slowdown has been particularly stark in the manufacturing sector, which historically has been a leading sector in driving the productivity of the aggregate U.S. economy. What makes this slowdown particularly puzzling is the fact that manufacturing accounts for ...
