A principal privately monitors an agent's hidden efforts. The agent's contract depends on the principal's unverifiable reports of her private information. How does the quality of the principal's private monitoring affect the optimal contract and agent productivity? When monitoring generates information that is at once imprecise (weak statistical power) but sensitive to effort (strong incentive
power) the principal is unable to commit not to be too tough on the agent. Improving a well-functioning monitoring system by adding new information that is weak in statistical power but strong in incentive power can cause the optimal dynamic contract to collapse and induce zero effort.

Firm Policies and Active Ownership Investors

Speaker: Vicente Cunat

15 November 2018 - T105 - From 2:00 pm to 3:15 pm


In November 2012, Norway’s sovereign wealth fund (NBIM) unexpectedly announced that it would improve specific governance dimensions of the firms in its portfolio. We this unexpected change of preferences as a natural experiment to understand shareholder influence among active ownership investors. We first document how the fund re-balanced its portfolio to achieve this objective. We then show how firms for which the fund is very important and also firms that are very important to the fund reacted by improving their governance. Finally, we document how, marginal investment changes and governance changes became more correlated in the new equilibrium.

Information Nudges and Self-Control

Economics & Decision Sciences

Speaker: Thomas Mariotti
Toulouse School of Economics

15 November 2018 - Building T - Room T015 - From 2:00 pm to 3:15 pm


We study the optimal design of information nudges for present-biased consumers who have to make sequential consumption decisions without exact prior knowledge of their long-term consequences. For arbitrary distributions of risk, there exists a consumer-optimal information nudge that is of cutoff type, recommending consumption or abstinence according to the magnitude of the risk. Under a stronger bias for the present, the target group receiving a credible signal to abstain must be tightened. We compare this nudge with those favored by a health authority or a lobbyist. When some consumers are more strongly present-biased than others, a traffic-light nudge is optimal.

“Globalization of Quantitative Policing: Between Management and Statactivism”

Accounting & Management Control

Speaker: Emmanuel DIDIER
EHESS Paris

9 November 2018 - HEC PARIS - Room T015 - From 10:00 am to 12:00 pm


Information policing seems to be pervading public security police all around
the world. This review asks whether this appellation describes a homogeneous
set of phenomena. Compstat was the first program to massively computerize
policing. The literature reviewed here follows its fate in the United
States and, on a global scale, in France, where the program was imported.
The review successively discusses the perspective of managers who were favorable
to the program and that of “statactivists,” activists who use statistics,
who were opposed to it. Despite the many differences intervened during
the importation process, especially in the balance of expertise and publicity,
some points seem to be common to both contexts, such as the building of
a computer infrastructure, a specific use of the data, and the constructive
tensions between the police institution and its critics.

Ethical Hacking & Cyber Security Awareness

Information Systems and Operations Management

Speaker: Mr. Sankarraj Subramanian
renowned international speaker, certified ethical hacker (CEH) & cyber security consultant with 13 years of experience in this field

9 November 2018 - HEC CAMPUS ROOM:T206 - From 10:30 am to 12:30 pm


In the current era of Internet enabled devices progressing towards the world of Internet of Things (IOT), there is a growing threat to the privacy and security of all the Internet users. Moreover, the rapid growth of mobile phone users is augmenting this problem. Given the current scenario of our growing dependence on Internet and mobile phones, there is a pressing need to understand the basics of our online vulnerabilities and cyber security. With this objective in view, this seminar will introduce the audience to:-



· Possible attacks that might happen to mobile devices leading to loss of data and other credentials and how to prevent such a situation.



· Hardware hacking, which explains how electronic devices can be a victim of virus attacks & RAT's; and the countermeasures that can possibly be adopted.



· Email security, with a view to protect emails from malicious hackers.



· Website security, where it is explained how Google can be used to extract information from the databases.



· Data recovery options, which are much needed for all removal storage mediums.



· Mobile tracking, which explains tracing lost mobile phones and the preventive mechanisms that can perhaps be adopted.

Can Financial Innovation Solve Household Reluctance to Take Risk ?

Using a large administrative panel of Swedish households, we document the fast and broad adoption of retail structured products, an innovative class of contracts offering non-linear exposures to equity markets. We first estimate the expected returns and markup of such products, and find them to be comparable to equity mutual funds. Households investing in retail structured products significantly increase the risky share of their financial wealth over the sample period, especially for households with an initially low risky share, lower wealth and IQ, and of older age. The relationships between household characteristics and the share of financial wealth invested is similar for structured products and cash, but differs strongly for equity mutual funds and stocks. A simple portfolio choice model shows that risk aversion cannot explain the demand for structured products and the empirical facts we observe, while loss aversion or misperception over their design can. Our results illustrate how security design can mitigate household reluctance to take financial risk.

Women Innovators: Challenges and Opportunities

Innovation typically involves generating multiple novel ideas and selecting the most promising one for implementation. In this research, I examine how gender influences idea selection during the innovation process. I theorize that although women are equally capable as men in generating highly novel ideas, women and men differ in “novelty avoidance” during idea selection - the extent to which individuals refrain from pursuing the most novel ideas they have generated. In a laboratory study where students were instructed to make creative short-films for the university, I found support of the hypothesis. In a second laboratory study where students were instructed to make creative photo collages for the university, I found that the gendered effect is moderated by the presence of women in judging panels. Specifically, women’s novelty avoidance tendency is mitigated when there are more women appeared in the judging panel. In the third study conducted on a creative crowdsourcing platform featuring a sample of freelancers, I replicated the gender difference in novelty avoidance and found that fear of social backlash from demonstrating high creativity explains women’s novelty avoidance tendency. Overall, my work advances current understanding of the challenges and opportunities that women innovators face, thereby helping to close the gender gap in innovation and entrepreneurship.

The Double-Edged Sword Effect of Team-Level Proactive Personality on Team Performance: Team Potency and Team Cohesion as Mechanisms

Management & Human Resources

Abstract

While research has largely shown a positive linear relationship between proactive personality and job performance at the individual level, we know relatively little about how proactive personality functions and whether the same relationship holds at the team level. This study proposes a curvilinear relationship between team-level proactive personality and team performance and considers team potency and team cohesion as two explanatory mechanisms. In Study 1, using data collected from 94 teams in four companies, we established an inverted-U-shaped relationship between team-level proactive personality and team performance. In Study 2, using data collected from a sample of 101 nursing teams from three hospitals, we replicated the inverted-U-shaped relationship and further demonstrated that the relationship is mediated by team potency and team cohesion, respectively. Specifically, at low to moderate levels, team-level proactive personality increases team potency and team cohesion, but at moderate to high levels, such relationships become negative. Team potency and team cohesion are positively related to team performance and thus mediate the relationship between team-level proactive personality and team performance.

Keywords:
team-level proactive personality; team potency; team cohesion; curvilinear relationship
