Latency delays - known as "speed bumps" - are an intentional slowing of order flow by exchanges. Supporters contend that delays protect market makers from high-frequency arbitrage, while opponents warn that delays promote "quote fading" by market makers. We construct a model of informed trading...

Trading activity surges associated with latency arbitrage are costly, as they lead to both lower liquidity and inefficient investments in order processing capacity that remains idle 90% of the time. A congestion message fee on liquidity-taking orders alleviates both concerns. The fee surges...

Financial markets face the constant threat of cyber attacks. We develop a principal-agent model of cyber-attacking with fee-paying clients who delegate security decisions to financial platforms. We derive testable implications about clients' vulnerability to cyber attacks and about the fees...

Financial services are delivered almost exclusively online and cyber attackers have taken notice. We develop a principal-agent model with fee-paying clients who delegate security decisions to financial platforms that are subject to cyber attacks that steal data or assets. We derive testable...

Central banks may engage in large-scale lending and asset purchases to stabilize financial markets and implement monetary policy during crises. The ability of these actions to restore financial market functioning is well documented; however, they come with costs. We provide a literature review of...

This paper examines the role of rewards-based and equity-based crowdfunding in funding new businesses. In this model, crowdfunding is a unique technology that serves as a real option for production and eliminates downside risk. It affords entrepreneurs who face uncertain consumer demand a viable...

In the onset of the COVID-19 crisis, central banks purchased large volumes of assets in an effort to keep markets operational. We model one such central bank, which purchases assets from dealers to alleviate balance sheet constraints. Asset purchases can prevent market breakdown, improve price...

The primary focus of this paper is to study conflict of interest in the brokerage market. Brokers face a conflict of interest when the commissions they receive from investors differ from the costs imposed by different trading venues. I construct a model of limit order trading in which brokers...

We present a model of market makers subject to recent banking regulations: liquidity and capital constraints in the style of Basel III and a position limit in the style of the Volcker Rule. Regulation causes market makers to reduce their intermediation by refusing principal positions. However,...
