Numerical computation of Theta in a jump-diffusion model by integration by parts

Using the Malliavin calculus in time inhomogeneous jump-diffusion models, we obtain an expression for the sensitivity Theta of an option price (with respect to maturity) as the expectation of the option payoff multiplied by a stochastic weight. This expression is used to design efficient numerical algorithms that are compared with traditional finite-difference methods for the computation of Theta. Our proof can be viewed as a generalization of Dupire's integration by parts to arbitrary and possibly non-smooth payoff functions. In the time homogeneous case, Theta admits an expression from the Black–Scholes PDE in terms of Delta and Gamma but the representation formula obtained in this way is different from ours. Numerical simulations are presented in order to compare the efficiency of the finite-difference and Malliavin methods.     

Un siècle d'histoire coopérative à travers les statistiques de L'A.C.I.

Many authors have studied the quantitative evolution of the cooperative movement but their analysis was generally limited to a sector, a region or a specific period of time. Thanks to a collection by A. Leclerc (Moncton University, Canada) of all statistical information in possession of the International Cooperative Alliance, this study can rely on an exceptional database relating to the number of members affiliated to ICA since 1896. On the basis of this inventory, the authors try to determine the main orientations of the cooperative membership evolution over a period of nearly a century. In this article most of the results are presented by splitting the studied period into four development phases of the worldwide cooperative movement.     

Team Production with Punishment Option: Insights from a Real‐Effort Experiment

This paper analyzes the consequences of allowing for punishment in a real‐effort pair production experiment. The behavior of the best performer in the team differs on whether he or she can impose a sanction on the less performing partner. When sanctions are not allowed, good performers reduce their effort in response to the advantageous difference in scores; when they can impose sanctions, their change in effort is no longer related to the difference in scores. To some extent, a sanction mechanism allows good performers to focus on their own performance. In the case of costless sanctions, not sanctioning a partner who under‐performs, what we refer to as forgiveness, prompts the latter to improve his or her performance, but applying the sanction has a stronger push effect.

Household Satellite Account for France

We estimate in a household satellite account (HHSA) the value of French domestic production in 2010 and 1998, using the input method and following Eurostat's recommendations. In line with previous studies, we find that extending the system of national accounts (SNA) frontier of production to domestic activities (house chores, cooking, care …) has a sizeable effect on key macroeconomic indicators (+33 percent GDP, ?5 p.p. GDP growth, +50 percent disposable income, +58 percent consumption, and ?10 p.p. of purchasing power growth). We conduct a sensitivity analysis to various methodological issues which have not yet been settled by an international benchmark. Quantitatively, the two most important issues are the boundary of household production—we favor a relatively narrow definition—and the use of a gross or a net wage—we prefer gross wage‐. However, estimates are much less sensitive to otherwise greatly debated issues such as which substitute wage to use.

RESEARCH ON STRUCTURAL HOLES: AN ASSESSMENT ON MEASUREMENT ISSUES

Social capital theory generally analyses network structures by focusing on the connections between players. However, it has been suggested by several authors that the absence of relations in a network or ‘structural holes’ is meaningful. The aim of our paper is to provide a global survey and appraisal of the academic research on structural holes and discuss its main measurements. We adopt a bibliometric approach and identify a typology of practices, developments, and issues related to structural holes. We highlight a strand of work on operationalization of structural holes, and discuss the various measures they propose. We provide numerical examples emphasizing the respective advantages and limitations of the studied measures. Based on our results, we propose a guide to using existing measures of structural holes according to the type (simple or complex) of network.     

Assessing the losses in euro area potential productivity due to the financial crisis

In this article, we show that the recent financial crisis has significantly affected the potential total factor productivity (TFP) of the four largest euro area economies, as well as that of the rest of the euro area. We used a reduced-form equation of TFP, based on an approach recently developed by Cahn and Saint-Guilhem (2010). Our empirical findings show that the permanent impact on potential TFP varies across countries from –3.9 points to –1.3 points in Q2 2012. When these losses are incorporated, TFP gaps develop closely in line with capacity utilization rates (CUR). Moreover, in the case of France, including CUR in our TFP model improves the quasi-real-time reliability of TFP gap estimates.     

Affective Computing in Marketing: Practical Implications and Research Opportunities Afforded by Emotionally Intelligent Machines

After years of using AI to perform cognitive tasks, marketing practitioners can now use it to perform tasks that require emotional intelligence. This advancement is made possible by the rise of affective computing, which develops AI and machines capable of detecting and responding to human emotions. From market research, to customer service, to product innovation, the practice of marketing will likely be transformed by the rise of affective computing, as preliminary evidence from the field suggests. In this Idea Corner, we discuss this transformation and identify the research opportunities that it offers.

     

Hidden persuasions in soap operas: damaged heroines and negative consumer effects

Sex and death, subjects traditionally considered taboo, are now presented in advertisements. Focusing on the French cultural context, this paper analyses whether these topics are still considered taboo in our society. We use the concept of taboo as studied in ethnology and psychoanalysis, which makes the reticence of consumers easier to understand and aids the study of taboos in relation to cultural context. We analyse the use of taboos in advertising, reviewing the literature on the impact of the use of death and sex in advertising, and relating it to ethical issues and cultural aspects. We then present a survey analysing whether French consumers find it acceptable to present taboos in advertising and identifying which individual characteristics affect attitudes towards taboos in advertising. Women and seniors are particularly hostile to sex and death in advertising, while young people find these themes more acceptable. The general attitude towards advertising also appears to have a strong impact on attitudes. We draw managerial implications from these results.
