This paper is a description and summary of existing questions and sources of data on stock options with an emphasis on two issues; what are the issues surrounding stock options in the national accounts and what value do employees place on stock options? We survey many existing data sources and outline some of the ways these data can be used to answer questions about the use and impact of employee stock options. The data sources include administrative records from individual firms, survey data of employee perceptions, disclosure filings with the SEC and other government, nonprofit, and international sources. We explore ways to investigate the value of options to employees and their cost to the firms using data on employee exercise decisions. Finally, we discuss the implications of our findings for public policy, the reporting of stock options, and how options are considered in the national accounts.
