We analyze costly quality disclosure with horizontally differentiated products under duopoly and monopoly, and characterize the effect of competition on disclosure and welfare. We show that expected disclosure is higher under monopoly than under duopoly, and the welfare comparison depends on the level of disclosure cost: when the disclosure cost is low, welfare is higher under monopoly than duo...

Microaggregation is a statistical disclosure control technique for mi-crodata. Raw microdata (i. e. individual records) are grouped into small aggregates prior to publication. Each aggregate should contain at least k records to prevent disclosure of individual information. Fixed-size microaggregation consists of taking xed-size microaggregates (size k). Data-oriented microaggregation (with vari...

It is widely believed that disclosure quality improves investors’ welfare by reducing cost of capital in a competitive market. This paper examines this conventional wisdom by studying a production economy in which disclosure influences a firm’s investment decisions. I demonstrate three points. First, cost of capital could increase with disclosure quality when new investment is sufficiently elas...

This study used a new measure, the Disclosure Grid, to assess the disclosure patterns of 89 gay men and 55 lesbians across their entire social network. In addition to assessing disclo...

In this paper, we examine the incentives for firms to voluntarily disclose otherwise private information about quality attributes of differentiated products when those products have multiple attributes and consumers are heterogeneous in their tastes over these attributes. In particular, we focus on whether the so-called “unraveling result”—in equilibrium, firms fully disclose the quality of the...

CONTEXT Public disclosure of quality data on health maintenance organizations (HMOs) might improve public accountability, inform consumer decision making, and promote quality improvement. But, because disclosure is voluntary, some HMOs could subvert these objectives by refusing to release unfavorable data. OBJECTIVE To determine the association between HMO quality of care and withdrawal from ...
