Costs of Managerial Attention and Activity as a Source of Sticky Prices: Structural Estimates from an Online Market
Abstract: We study price dynamics for computer components sold on a price-comparison website.
Our fine-grained data—a year of hourly price data for scores of rival retailers—allow us to
estimate a dynamic model of competition, backing out structural estimates of managerial frictions.
The estimated frictions are substantial, concentrated in the act of monitoring market conditions
rather than entering a new price. We use our model to simulate the counterfactual gains from
automated price setting and other managerial changes. Coupled with supporting reduced-form
statistical evidence, our analysis provides a window into the process of managerial price setting
and the microfoundation of pricing inertia, issues of growing interest in industrial organization and
macroeconomics.

How to Identify Good Teachers? Teacher Evaluations and Student Achievement
The fact that teachers matter for student achievement is largely documented.Yet, identifying what makes good teaching has proven difficult, in spite of the large amount of attention this question has received in the last decade. In this paper, I shift the focus from the usual observable socio-demographic characteristics to the systematic and administrative evaluations of teachers by their hierarchy. I analyze the three grades used to assess teachers in secondary school in France: the certication grades, designed to assess teacher content-knowledge, the pedagogical grade, designed to assess pedagogical skills and the administrative grade, designed to assess administrative skills. I find that neither the certication grades (written nor oral) nor the administrative grade are signicantly associated with student achievement gains. The only evaluation grade statistically significantly associated with student achievement gains is the pedagogical grade: a standard deviation increase in this grade is associated with a two percent standard deviation increase in student achievement gains. This impact is on par with replacing an average teacher with a teacher at the 40th percentile of the teacher value-added distribution. Low income students are more sensitive to the pedagogical grade than others.These results has important implications for teacher training, hiring and assignment.

Automatic emotion recognition from physiological signals in a video game context
We present a multi-modal database for the analysis of human emotional states in the dynamic context of game. Peripheral physiological signals (ECG, EDA, respiration, EMG, temperature, pupil size), accelerometer signals, video were recorded for 58 participants who played 3 matches of a football simulation game (FIFA 2016) of different difficulty levels. After each match, participants were asked to annotate events which have triggered their emotions in terms of categorical emotions (boredom, frustration, anger, fear, happiness) and the arousal/valence score by reviewing the game recording. Global game experience in terms of the level of difficulty, implication and amusement evaluation and a ranking of the 3 matches were also collected from questionnaires. Combined with the global game experience evaluation, the database proposes a multi-scale view (local event scale and global match scale) for evaluating user emotions. Methods and results are presented from a local event view - classification of the emotional moment and no emotional moment, emotion recognition on the emotional moment, and from a global evaluation view - game experience evaluation. The database is made publicly available. The proposed database is the first available one which allows analysing the human emotional responses from physiological signals under dynamic interactive context of game.
