Using optionsand press-based proxies for CEO overconfidence (Malmendier and Tate 2005a, 2005b, 2008), we find that over the 1993-2003 period, firms with overconfident CEOs have greater return volatility, invest more in innovation, obtain more patents and patent citations, and achieve greater innovative success for given research and development (R&D)(More)
Barberis, Shleifer, and Vishny (1998) construct a model in which investors use the prevalence of past trend reversals as an indicator of the likelihood of future reversals. While such “regime-shifting” beliefs are consistent with a variety of psychological theories, other contrary predictions are consistent with the same theories. We report two experiments(More)
The need for policy makers to understand science and for scientists to understand policy processes is widely recognised. However, the science-policy relationship is sometimes difficult and occasionally dysfunctional; it is also increasingly visible, because it must deal with contentious issues, or itself becomes a matter of public controversy, or both. We(More)
We investigate the effect of standard setters in standard setting: We examine how certain professional and political characteristics of FASB members and SEC commissioners predict the accounting “reliability” and “relevance” of proposed standards. Notably, we find FASB members with backgrounds in financial services are more likely to propose standards that(More)
We use a laboratory market to investigate how the ability to hide orders affects traders’ strategies and market outcomes. We examine three market structures: Visible markets in which all orders must be displayed, Iceberg markets in which a minimum size must be displayed, and Hidden markets in which orders can be displayed, partially displayed, or completely(More)
We investigate multiple laboratory market settings that include informed traders (who observe fundamental information about security value) and uninformed traders (who observe only price histories). In our first setting, we prohibit informed traders from conditioning their trades on prices, as in the model of Hong and Stein (1999). Consistent with Hong and(More)
The computer-assisted design of soundscapes for virtual environments has received far less attention than the creation of graphical content. In this “think piece” we briefly introduce the principal characteristics of a framework under development that aims towards the creation of an automatic sonification of virtual worlds. As a starting point, the proposed(More)
SYNOPSIS: The Securities and Exchange Commission hereafter, SEC issued a call for comment on a proposal to adopt a roadmap for potential use of international financial reporting standards hereafter, IFRS by U.S. companies. We comment on five key issues raised by the SEC proposal. First, we propose that the need for a global regulator is overstated. A global(More)
Research on virtual worlds and environments has increased tremendously in the last decade, giving birth to a variety of applications spanning over several areas such as virtual reality, human-computer interaction, psychology and sociology, among others. In this paper we elaborate on one issue affecting the areas of virtual worlds and robotics: the lack of(More)
