We compare the forecasts of Quadratic Variation given by the Realized Volatility (RV) and the Two Scales Realized Volatility (TSRV) computed from high frequency data in the presence of market microstructure noise, under several different dynamics for the volatility process and assumptions on the noise. We show that TSRV largely outperforms RV, whether looking at bias, variance, RMSE...

This paper addresses the recent turn in strategy research to practice-based theorizing. Based on a data set of 51 meeting observations, the paper examines how strategy meetings are involved in either stabilizing existing strategic orientations or proposing variations that cumulatively generate change in strategic orientations. Eleven significant structuring characteristics of...

The neurophysiology of eye movements has been studied extensively, and several computational models have been proposed for decision-making processes that underlie the generation of eye movements towards a visual stimulus in a situation of uncertainty. One class of models, known as linear rise-to-threshold models, provides an economical, yet broadly applicable, explanation for the...

Non-monetary incentives in the form of awards have so far escaped the attention ofneconomists despite their widespread use. This paper presents an experiment conductednonline at IBM to assess the impact of these kinds of extrinsic incentives. Introducing a hypothetical award has statistically significant effects on stated contributions to a publicngood. Our design allows the...

If human beings care about their relative weight, a form of imitative obesity can emerge (in which people subconsciously keep up with the weight of the Joneses). Using Eurobarometer data on 29 countries, this paper provides cross-sectional evidence that overweight perceptions and dieting are influenced by a person’s relative BMI, and longitudinal evidence from the German...

"This paper studies the mental distress caused by bereavement. The largest emotional losses are from the death of a spouse; the second-worst in severitynare the losses from the death of a child; the third-worst is the death of a parent. The paper explores how happiness regression equations might benused in tort cases to calculate compensatory damages for emotional harm and pain-...

the judiciary, then political institutions, especially democracy. While there is a large consensus...
