Can managers influence the liquidity of their firms' shares? We use plausibly exogenous variation in the supply of public information to show that firms seek to actively shape their information environments by voluntarily disclosing more information than is mandated by market regulations and...

Public or partial disclosure of financial data is a key element in the design of a new regulatory environment. We study the costs and benefits of higher public access to financial data and analyze qualitatively how frequency, disclosure lag and granularity of such open data can be chosen to...

Derivatives exposures across large financial institutions often contribute to - if not necessarily create - systemic risk. Current reporting standards for derivatives exposures are nevertheless inadequate for assessing these systemic risk contributions. In this paper, I explain how a...

In July 2002, FINRA began mandatory dissemination of price and volume information for corporate bond trades. This paper, using recently released data, measures transparency's effect on trading activity and costs for the entire corporate bond market. Even though trading costs decrease...

Transparency is usually thought to reduce favoritism and corruption by facilitating monitoring by outsiders, but there is concern it can have the perverse effect of facilitating collusion by insiders. In response to vote trading scandals in the 1998 and 2002 Olympics, the International Skating...

Foreign-owned firms from advanced countries carry the culture of transparency in business transactions that is orthogonal to the culture of hiding and insider dealing in many developing economies and economies in transition. In this paper, we document this using administrative data on reported...

This paper examines the link between disclosure and the cost of capital. We exploit an exogenous cost of capital shock created by the Enron scandal in Fall 2001 and analyze firms' disclosure responses to this shock. These tests are opposite to the typical research design that analyzes cost of...

As barriers to international investment fall and technology improves, the cost advantages for a firm's securities to trade publicly in the country in which that firm is located and for that country to have a market for publicly traded securities distinct from the capital markets of other...

Although doctors and hospitals own their patients' medical records, state and federal laws require that they provide patients with a copy at "reasonable cost." We examine the effects of state laws that cap the fees that doctors and hospitals are allowed to charge patients for a copy of their...
