Calibrating noise to sensitivity in private data analysis

by Cynthia Dwork, Frank Mcsherry, Kobbi Nissim, Adam Smith - In Proceedings of the 3rd Theory of Cryptography Conference , 2006
"... Abstract. We continue a line of research initiated in [10, 11] on privacypreserving statistical databases. Consider a trusted server that holds a database of sensitive information. Given a query function f mapping databases to reals, the so-called true answer is the result of applying f to the datab ..."

Investor Protection and Corporate Governance

by Rafael La Porta, Florencio Lopez-de-Silanes, Andrei Shleifer, Robert Vishny , 1999
"... Recent research on corporate governance has documented large differences between countries in ownership concentration in publicly traded firms, in the breadth and depth of financial markets, and in the access of firms to external finance. We suggest that there is a common element to the explanations ..."

k-anonymity: a model for protecting privacy.

by Latanya Sweeney - International Journal on Uncertainty, Fuzziness and Knowledge-based Systems, , 2002
"... Consider a data holder, such as a hospital or a bank, that has a privately held collection of person-specific, field structured data. Suppose the data holder wants to share a version of the data with researchers. How can a data holder release a version of its private data with scientific guarantees ..."

Monetary Policy Shocks: What Have we Learned and to What End?

by Lawrence J. Christiano, Martin Eichenbaum , Charles L. Evans , 1998
"... This paper reviews recent research that grapples with the question: What happens after an exogenous shock to monetary policy? We argue that this question is interesting because it lies at the center of a particular approach to assessing the empirical plausibility of structural economic models that c ..."

Entrepreneurship: Productive, Unproductive, and Destructive

by William J. Baumol - JOURNAL OF POLITICAL ECONOMY , 1990
"... The basic hypothesis is that, while the total supply of entrepreneurs varies anlong societies, the productive contribution of the society's entrepreneurial activities varies much more because of their allocation between productive activities such as innovation and largely unproductive activitie ..."
