Real Effects of Price Transparency: Evidence from Steel Futures
Abstract
I study the real effects of product price transparency on producers and theircustomers. I use the introduction of steel futures at the London Metal Exchange
and the New York Mercantile Exchange in 2008 as a quasi-natural experiment. I
exploit the fact that the futures market did not become a new venue for buying
physical steel and did not change firms' hedging behavior significantly. Instead,
the creation of the futures market increased price transparency in the product
market. I compare steel products with futures traded on the exchanges to other
steel products in a difference-in-differences setting. I find that price transparency
reduces prices, producer surplus and customer material costs. Price transparency
further reduces input cost dispersion within narrowly defined customer industries
and increases the market share of low-cost producers and aggregate producer
productivity.
