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.

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 ...

Market Concentration in Fintech
This paper discusses concentration in consumer credit markets with a focus on fintech lenders and residential mortgages. We present evidence that shows that concentration among fintech lenders is significantly higher than that for bank lenders and other nonbank lenders. The data also show that the overall concentration in mortgage lending has declined between 2011 and 2019, driven mostly by a reduction in concentration among bank lenders. We present a simple model to show that changes in lender financial technology (interpreted as improvements in quality of loan services) explain more than ...

Real Estate Commissions and Homebuying
We construct a model of home search and buying in the U.S. housing market and evaluate the commission paid to homebuyers' agents. In the model, as in reality, homebuyers enjoy free house showings without having to pay their agents out of pocket. Buyers' agents receive a commission equal to 3% of the house price only after a home is purchased. We show this compensation structure deviates from cost basis and may lead to elevated home prices, overused agent services, and prolonged home searches. Based on the model, we discuss policy interventions that may improve housing search efficiency and ...

Faster payments: market structure and policy considerations
The U.S. payments industry is in the process of developing ubiquitous, safe, faster electronic solutions for making a broad variety of business and personal payments. How this market for faster payments will evolve will be shaped by a range of economic forces, such as economies of scale and scope, network effects, switching costs, and product differentiation. Emerging technologies could alter these forces and lead to new organizational arrangements or market structures that are different from those in legacy payment markets to date. In light of this uncertainty, this paper examines three ...

The Shift from Active to Passive Investing: Potential Risks to Financial Stability?
The past couple of decades have seen a significant shift in assets from active to passive investment strategies. We examine the potential effects of this shift on financial stability through four different channels: (1) effects on investment funds? liquidity transformation and redemption risks; (2) passive strategies that amplify market volatility; (3) increases in asset-management industry concentration; and (4) the effects on valuations, volatility, and comovement of assets that are included in indexes. Overall, the shift from active to passive investment strategies appears to be increasing ...
Working Paper
Bank Fees, Aftermarkets, and Consumer Behavior
Fees for banking services have been a policy concern for over 20 years and the subject of several government agencies studies, which focused on the magnitude, incidence, or disclosure of such fees. Using a sample of single market banks, I study the relationship between market-level consumer characteristics and bank fee revenue, fees, and bank return on assets (ROA) to infer consumer and firm behavior. Of particular interest, I use county-level IRS tax records as a measure of the consumer income distribution, but my analysis also includes measures of age and education distributions. I find ...

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 ...
