Implications of rational inattention

by Christopher A. Sims - JOURNAL OF MONETARY ECONOMICS , 2002
"... A constraint that actions can depend on observations only through a communication channel with finite Shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems. The resulting theory looks enough like fa ..."

Adolescence-limited and life-course-persistent antisocial behavior: A developmental taxonomy

by Terrie E. Moffitt - PSYCHOLOGICAL REVIEW , 1993
"... A dual taxonomy is presented to reconcile 2 incongruous facts about antisocial behavior: (a) It shows impressive continuity over age, but (b) its prevalence changes dramatically over age, increasing almost 10-fold temporarily during adolescence. This article suggests that delinquency conceals 2 dist ..."

The performance of mutual funds in the period 1945-1964

by Michael C. Jensen - JOURNAL OF FINANCE , 1968
"... In this paper I derive a risk-adjusted measure of portfolio performance (now known as "Jensen's Alpha") that estimates how much a manager's forecasting ability contributes to the fund's returns. The measure is based on the theory of the pricing of capital assets by Sharpe (1 ..."

No Contagion, Only Interdependence: Measuring Stock Market Co-Movements

by Kristin J. Forbes, Roberto Rigobon - Journal of Finance , 2001
"... Heteroscedasticity biases tests for contagion based on correlation coefficients. When contagion is defined as a significant increase in market co-movement after a shock to one country, previous work suggests contagion occurred during recent crises. This paper shows that correlation coefficients are ..."

Illusion and well-being: A social psychological perspective on mental health.

by Shelley E Taylor , Jonathon D Brown , Nancy Cantor , Edward Emery , Susan Fiske , Tony Green-Wald , Connie Hammen , Darrin Lehman , Chuck Mcclintock , Dick Nisbett , Lee Ross , Bill Swann , Joanne - Psychological Bulletin, , 1988
"... Many prominent theorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggests that overly positive selfevaluations, exaggerated perceptions of control or mastery, and unrealistic optimism are charac ..."

that they are happier, better adjusted, and more skilled on a variety of tasks than most other people, such perceptions provide evidence suggestive of an illusion. Illusions about the future are operationally difficult to establish because no one knows what the future will bring. If it can be shown, however, that most

Statistical methods for identifying differentially expressed genes in replicated cDNA microarray experiments

by Sandrine Dudoit, Yee Hwa Yang, Matthew J. Callow, Terence P. Speed - STATISTICA SINICA , 2002
"... DNA microarrays are a new and promising biotechnology whichallows the monitoring of expression levels in cells for thousands of genes simultaneously. The present paper describes statistical methods for the identification of differentially expressed genes in replicated cDNA microarray experiments. A ..."

into account the dependence structure between the gene expression levels. No specific parametric form is assumed for the distribution of the test statistics and a permutation procedure is used to estimate adjusted p-values. Several data displays are suggested for the visual identification of differentially

The Determinants of Credit Spread Changes.

"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

are highly crosscorrelated, and principal components analysis implies they are mostly driven by a single common factor. Although we consider several macro-economic and financial variables as candidate proxies, we cannot explain this common systematic component. Our results suggest that monthly credit spread

Conflict monitoring and anterior cingulate cortex: An update

by Matthew M. Botvinick, Jonathan D. Cohen, Cameron S. Carter - Trends in Cognitive Science , 2004
"... One hypothesis concerning the human dorsal anterior cingulate cortex (ACC) is that it functions, in part, to signal the occurrence of conflicts in information processing, thereby triggering compensatory adjustments in cognitive control. Since this idea was first proposed, a great deal of relevant em ..."

Performance matched discretionary accrual measures

by S. P. Kothari, Andrew J. Leone, Charles E. Wasley, Jerry Zimmerman, S. P. Kothari, Arthur Andersen - Journal of Accounting and Economics , 2005
"... Using discretionary accruals to test for earnings management and market efficiency is commonplace in the literature. We develop a well-specified (rejects the null hypothesis, when it’s true, at the test’s nominal significance level) and powerful (rejects a false null hypothesis with high probability ..."

probability) measure of discretionary accruals. A key feature of the discretionary accrual measure is that it is adjusted for the accrual performance of a matched firm where matching is on the basis of return on assets and industry. We advocate matching to control for the impact of performance on accruals

Developments in the Measurement of Subjective Well-Being

by Daniel Kahneman , Alan B Krueger - Psychological Science. , 1993
"... F or good reasons, economists have had a long-standing preference for studying peoples' revealed preferences; that is, looking at individuals' actual choices and decisions rather than their stated intentions or subjective reports of likes and dislikes. Yet people often make choices that b ..."

by continuously adjusting a dial. These studies yield a temporal profile of moment-to-moment subjective experience. The results of these experiments provide some insights into more standard measures of satisfaction, and lend support for the usefulness of making a distinction between experienced utility
