Can Earnings Calls Be Used to Gauge Labor Market Tightness?
An index that uses textual analysis of earnings calls to track labor issues appears to be highly correlated to one measure of labor market tightness.
Unlike Others, the Top Earners See Strong Pay Growth Beyond Age 35
An analysis shows that the top 2% of male earners saw strong pay growth after 35. For the bottom 2% and the median worker, the pace declined or plateaued.
Does Worker Scarcity Spur Investment, Automation and Productivity? Evidence from Earnings Calls
An analysis suggests labor issues like higher wages and hiring difficulties have prompted some firms to invest in automation, leading to productivity growth.

Taxation of human capital and wage inequality: a cross-country analysis
Wage inequality has been significantly higher in the United States than in continental European countries (CEU) since the 1970s. Moreover, this inequality gap has further widened during this period as the US has experienced a large increase in wage inequality, whereas the CEU has seen only modest changes. This paper studies the role of labor income tax policies for understanding these facts, focusing on male workers. We construct a life cycle model in which individuals decide each period whether to go to school, work, or stay non-employed. Individuals can accumulate skills either in school or ...

Scalable versus Productive Technologies
CORRECT ORDER OF AUTHORS: Hubmer, Chan, Ozkan, Salgado, Hong. Do larger firms have more productive technologies, are their technologies more scalable, or both? We use administrative data on Canadian and US firms to estimate a joint distribution of output elasticities of capital, labor, and intermediate inputs—thus, returns to scale (RTS)—along with total factor productivity (TFP). We find significant heterogeneity in RTS across firms within industries. Furthermore, larger firms operate technologies with higher RTS, whereas the largest firms do not exhibit the highest TFP. Higher RTS for ...

Consumption Dynamics and Welfare Under Non-Gaussian Earnings Risk
CORRECT ORDER OF AUTHORS: Fatih Guvenen, Serdar Ozkan, and Rocio Madera. The order of coauthors has been assigned randomly using AEA’s Author Randomization Tool. Recent empirical studies document that the distribution of earnings changes displays substantial deviations from lognormality: in particular, earnings changes are negatively skewed with extremely high kurtosis (long and thick tails), and these non-Gaussian features vary substantially both over the life cycle and with the earnings level of individuals. Furthermore, earnings changes display nonlinear (asymmetric) mean reversion. In ...

Scalable vs. Productive Technologies
Do larger firms have more productive technologies or are their technologies more scalable, or both? We use administrative data on Canadian and US firms to estimate flexible nonparametric production functions. Our estimation results in a joint distribution of output elasticities of capital, labor, and intermediate inputs---therefore, returns to scale (RTS)---along with total factor productivity (TFP). We find significant heterogeneity in both RTS and TFP across firms. Larger firms operate technologies with higher RTS, both across and within industries. Higher RTS for large firms are entirely ...

Income Differences and Health Disparities: Roles of Preventive vs. Curative Medicine
Using data from the Medical Expenditure Panel Survey (MEPS) I find that early in life the rich spend significantly more on health care, whereas from middle to very old age the poor outspend the rich by 25% in the US. Furthermore, while low-income individuals are less likely to incur medical expenses, they are more prone to experiencing extreme expenses when they do seek care. To account for these facts, I develop and estimate a life-cycle model of two types of health capital: physical and preventive. Physical health capital determines survival probabilities, whereas preventive health capital ...
AI Optimism and Uncertainty: What Can Earnings Calls Tell Us Post-ChatGPT?
An analysis of earnings calls shows that America’s corporate leaders are talking much more about AI. It also reveals an increase in perceived risk in this new technology.
