September 2017Crude by Rail, Option Value, and Pipeline Investment
with Ryan Kellogg: w23855
The U.S. shale boom has profoundly increased crude oil movements by both pipelines–the traditional mode of transportation–and railroads. This paper develops a model of how pipeline investment and railroad use are determined in equilibrium, emphasizing how railroads' flexibility allows them to compete with pipelines. We show that policies that address crude-by-rail's environmental externalities by increasing its costs should lead to large increases in pipeline investment and substitution of oil flows from rail to pipe. Similarly, we find that policies enjoining pipeline construction would cause 80-90% of the displaced oil to flow by rail instead.
September 2013The Effects of Mandatory Transparency in Financial Market Design: Evidence from the Corporate Bond Market
with Paul Asquith, Parag Pathak: w19417
Many financial markets have recently become subject to new regulations requiring transparency. This paper studies how mandatory transparency affects trading in the corporate bond market. In July 2002, TRACE began requiring the public dissemination of post-trade price and volume information for corporate bonds. Dissemination took place in Phases, with actively traded, investment grade bonds becoming transparent before thinly traded, high-yield bonds. Using new data and a differences-in-differences research design, we find that transparency causes a significant decrease in price dispersion for all bonds and a significant decrease in trading activity for some categories of bonds. The largest decrease in daily price standard deviation, 24.7%, and the largest decrease in trading activity, 41...
August 2010The Market for Borrowing Corporate Bonds
with Paul Asquith, Andrea S. Au, Parag A. Pathak: w16282
This paper describes the market for borrowing corporate bonds using a comprehensive dataset from a major lender. The cost of borrowing corporate bonds is comparable to the cost of borrowing stock, between 10 and 20 basis points per year. Factors that increase borrowing costs are loan size, percentage of inventory lent, rating, and borrower identity. Trading strategies based on cost or amount of borrowing do not yield excess returns. Bonds with corresponding CDS contracts are more actively lent than those without. Finally, the 2007 Credit Crunch did not affect average borrowing cost or loan volume, but increased borrowing cost variance.
