Working Paper
Dotcom Extreme Underpricing
We conjecture that the Dotcom abnormal underpricing resulted from the emergence a large cohort of firms racing for market leadership/survivorship. Fundamentals pricing at the IPO was part of their strategy. Consistent with our conjecture, firms? strategic goals and characteristics fully explain the abnormal underpricing. Contrary to alternatives explanations, underpricing was not associated with top underwriting; there was no deterioration of issuers? quality; and top underwriters and analysts became more selective.

Organizations, Skills, and Wage Inequality
We extend an on-the-job search framework in order to allow firms to hire workers with different skills and skills to interact with firms? total factor productivity (TFP). Our model implies that more productive firms are larger, pay higher wages, and hire more workers at all skill levels and proportionately more at higher skill types, matching key stylized facts. We calibrate the model using five educational attainment levels as proxies for skills and estimate nonparametrically firm-skill output from the wage distributions for different educational levels. We consider two periods in time (1985 ...

The Dotcom Bubble and Underpricing: Conjectures and Evidence
We provide conjectures for what caused the price spiral and the high underpricing of the dotcom bubble of 1999?2000. We raise two conjectures for the price spiral. First, given the uncertainty about the growth opportunities generated by the new technologies and their spillover effects across technology industries, investors saw the inflow of a large number of high-growth firms as a sign of high growth rates for the market as a whole. Second, investors interpreted the wave of highly underpriced IPOs as an opportunity to obtain gains by investing in newly public companies. The underpricing ...

The Evolution of the Labor Share across Developed Countries
In most developed countries, the share of output accruing to labor has declined over the last 20 years. However, the underlying reasons for the decrease may have differed in the United States and other developed countries. In this Commentary, we examine some of the explanations economists have proposed for the decline in the labor share and discuss how well these explanations account for the decline across developed countries.

A Spanner in the Works: Restricting Labor Mobility and the Inevitable Capital-Labor Substitution
We model an environment with overlapping generations of labor to show that policies restricting labor mobility increase a firm's monopsony power and labor turnover costs. Subsequently, firms increase capital expenditure, altering their optimal capital-labor ratio. We confirm this by exploiting the statewide adoption of the inevitable disclosure doctrine (IDD), a law intended to protect trade secrets by restricting labor mobility. Following an IDD adoption, local firms increase capital expenditure (capital-labor ratio) by 3.5 percent (5.5 percent). This result is magnified for firms with ...

Costly Information Intermediation as a Natural Monopoly
In this paper, we show that information trade has similar characteristics to a natural monopoly, where competition may be detrimental to efficiency due either to the duplication of direct costs or the slowing down of information dissemination. We present a model with two large populations in which consumers are randomly matched to providers on a period-by-period basis. Despite a moral hazard problem, cooperation can be sustained through an institution that gives incentives to information exchange. We consider different information pricing mechanisms (membership vs. buy and sell) and different ...

The Hedgehog’s Curse: Knowledge Specialization and Displacement Loss
This paper studies the impact of knowledge specialization on earnings losses following displacement. We develop a novel measure of the specialization of human capital, based on how concentrated the knowledge used in an occupation is. Combining our measure with individual labor histories from the NLSY 79-97 and Norway’s LEED, we show that workers with more specialized human capital suffer larger earnings losses following exogenous displacement. A one standard deviation increase in pre-displacement knowledge specialization increases the earnings losses post-displacement by 3 to 4 pp per year ...
Working Paper
Dotcom Price Spiral
We show that during the bubble implied growth rates coming from the underpricing of IPO market explains short term returns on the NASDAQ index. This result remains even if we replace actual underprice for others different instruments for underpricing that are based on predetermined variables and not correlated to market returns. We also do placebo tests to assess the relation between underpricing and NASDAQ returns over other periods. We show that growth proxies that are not contaminated by the booms and busts of the stock market are uncorrelated with the returns on the NASDAQ index in ...

Revisiting Wage Growth after the Recession
In this Commentary, we show that realized wage growth since 2015 has mostly been at a rate that would be expected given observed rates of inflation and labor productivity growth. Moreover, labor productivity growth has been in line with its potential over the same period. This picture of the post-recession recovery of wages is very different from the one we observed in an earlier analysis, when all we had were data up through the end of 2015. The reasons underlying the difference are large revisions in labor productivity data and upticks in the inflation rate and labor productivity growth ...

US Labor Market after COVID-19: An Interim Report
Headline numbers have shown that the US labor market has recovered the jobs lost during the pandemic. Nevertheless, there is significant variation in the recovery across states and counties and across occupations and industries. Using the available data from the monthly Current Population Survey and the Bureau of Labor Statistics’ State and Metro Area Employment, Hours, and Earnings for January 2019 to August 2022, we present the changing patterns in the labor market. We also highlight some possible underlying reasons that are correlated with the varying patterns across groups and space. ...
