L'effet des récompenses sur l'état de santé psychologique des travailleurs: les mécanismes sous‐jacents

The effort‐reward imbalance (ERI) model in the workplace (Siegrist, 1996 ) suggests that inequity of rewards contributes to a degradation of mental health through a process of devaluation. The objective of our study is to test this hypothesis empirically. Data were collected from 659 agents in three call centres located in the province of Quebec. A bootstrap mediation test show that perceived inequity with respect to rewards (recognition, promotion, job security) affects the level of psychological distress through the perception of being valued by the organization. Perceived inequity affects mental health because it signals to workers the extent to which they are valued by their organization. Our correlational study provides evidence of the internal validity of the ERI model. Copyright © 2017 ASAC. Published by John Wiley & Sons, Ltd.     

Servir les clients avec le sourire: Source d'épuisement ou de performance chez les employés de centres d'appels?

This study examines the relationships between emotional labour (surface acting, deep acting, and natural expression of positive emotions) and emotional exhaustion and service performance among 215 call centre employees. Of the hypotheses concerning the relation between the three emotional regulation strategies to emotional exhaustion and to service performance, only natural expression of positive emotion is significantly related to both consequences. Results also suggest that neuroticism moderates the link between deep acting and emotional exhaustion: employees with low levels of neuroticism seem more emotionally exhausted when they use deep acting.

Mode coopétition dans un cluster culturel? Le cas du secteur circassien montréalais

We explore the relevance of the « coopetition » concept within Montreal's circus sector and the Montréal Complètement Cirque festival in particular. Our analysis is based on the cluster phenomena found in coopetition studies, which is a strategy used by companies in the technology sector. We formulate propositions that suggest these collaborative practices allow reduce tensions related to the innovation and creative processes' intrinsic uncertainty and also moderate the effects of a firms' limited resources. These practices are also related to public policies aimed at ensuring the sector's sustainability, the existence of interpersonal relations, and the need for more visibility on the sector and its actors.

ROBUST UTILITY MAXIMIZATION WITH LÉVY PROCESSES

We study a robust portfolio optimization problem under model uncertainty for an investor with logarithmic or power utility. The uncertainty is specified by a set of possible Lévy triplets, that is, possible instantaneous drift, volatility, and jump characteristics of the price process. We show that an optimal investment strategy exists and compute it in semi‐closed form. Moreover, we provide a saddle point analysis describing a worst‐case model.     

POWER UTILITY MAXIMIZATION IN CONSTRAINED EXPONENTIAL LÉVY MODELS

We study power utility maximization for exponential Lévy models with portfolio constraints, where utility is obtained from consumption and/or terminal wealth. For convex constraints, an explicit solution in terms of the Lévy triplet is constructed under minimal assumptions by solving the Bellman equation. We use a novel transformation of the model to avoid technical conditions. The consequences for q‐optimal martingale measures are discussed as well as extensions to nonconvex constraints.     

Financial models with defaultable numéraires

Financial models are studied where each asset may potentially lose value relative to any other. Conditioning on nondevaluation, each asset can serve as proper numéraire and classical valuation rules can be formulated. It is shown when and how these local valuation rules can be aggregated to obtain global arbitrage‐free valuation formulas.     

THE NUMÉRAIRE PROPERTY AND LONG‐TERM GROWTH OPTIMALITY FOR DRAWDOWN‐CONSTRAINED INVESTMENTS

We consider the portfolio choice problem for a long‐run investor in a general continuous semimartingale model. We combine the decision criterion of pathwise growth optimality with a flexible specification of attitude toward risk, encoded by a linear drawdown constraint imposed on admissible wealth processes. We define the constrained numéraire property through the notion of expected relative return and prove that drawdown‐constrained numéraire portfolio exists and is unique, but may depend on the investment horizon. However, when sampled at the times of its maximum and asymptotically as the time‐horizon becomes distant, the drawdown‐constrained numéraire portfolio is given explicitly through a model‐independent transformation of the unconstrained numéraire portfolio. The asymptotically growth‐optimal strategy is obtained as limit of numéraire strategies on finite horizons.     

RATING BASED LÉVY LIBOR MODEL

In this paper, we consider modeling of credit risk within the Libor market models. We extend the classical definition of the default‐free forward Libor rate and develop the rating based Libor market model to cover defaultable bonds with credit ratings. As driving processes for the dynamics of the default‐free and the predefault term structure of Libor rates, time‐inhomogeneous Lévy processes are used. Credit migration is modeled by a conditional Markov chain, whose properties are preserved under different forward Libor measures. Conditions for absence of arbitrage in the model are derived and valuation formulae for some common credit derivatives in this setup are presented.     

A variation of the Azéma martingale and drawdown options

In this paper, we derive a variation of the Azéma martingale using two approaches—a direct probabilistic method and another by projecting the Kennedy martingale onto the filtration generated by the drawdown duration. This martingale links the time elapsed since the last maximum of the Brownian motion with the maximum process itself. We derive explicit formulas for the joint densities of , which are the first time the drawdown period hits a prespecified duration, the value of the Brownian motion, and the maximum up to this time. We use the results to price a new type of drawdown option, which takes into account both dimensions of drawdown risk—the magnitude and the duration.     

Using World Café and drama to explore older people's experience of financial products and services

This paper examines a novel strategy to get older people talking about their financial needs and equity release. A questionnaire was used to identify issues which were then written into a drama on equity release products and bank accounts. This dramatic representation of the issues preceded discussion among older people at a World Café event – a format that involves a series of circulating focus groups where concepts can be discussed in depth and recorded. The drama offered an initial stimulus of alternative and opposing opinions and facilitated conversation about financial products and services which are often considered uninteresting and private. The aim was to record ideas in the discussions that would benefit the production and design of innovative financial products that would meet the needs of people over 50 years. Further, as a technique, the combination of drama, used to stimulate discussion, and the World Café format, to obtain and record consumer opinions, arguably offers innovative options to researchers in other sectors of product or service consumption.     

Do single‐stock circuit breakers provide a safety net for Canadian investors?

This study looks at the market impact of recent regulatory changes in Canada that provide for trading halts on individual stocks that experience large upside or downside movements. The focus is on all stocks traded on the Toronto Stock Exchange since the inception of the single‐stock circuit breaker rule (SSCB) in February 2012, to replace the short‐sale uptick rule. The results support pricing efficiency: material information that caused the circuit breaker is incorporated in stock prices on the day of the halt (neither overreaction nor underreaction), with no decline in market liquidity. Using trade‐by‐trade data constructed on five‐minute trading intervals, we refine the daily results, and show that shocks in realized volatility are focused in the 10‐minute trading interval surrounding the halts. While circuit breakers provide a limited safety net for investors when their stocks are subject to severe volatility, they do not allow for a quick turnaround for stocks experiencing severe price decline events.     

NO‐ARBITRAGE IN A NUMÉRAIRE‐INDEPENDENT MODELING FRAMEWORK

The classic approach to modeling financial markets consists of four steps. First, one fixes a currency unit. Second, one describes in that unit the evolution of financial assets by a stochastic process. Third, one chooses in that unit a numéraire, usually the price process of a positive asset. Fourth, one divides the original price process by the numéraire and considers the class of admissible strategies for trading. This approach has one fundamental drawback: Almost all concepts, definitions, and results, including no‐arbitrage conditions like NA, NFLVR, and NUPBR depend by their very definition, at least formally, on initial choices of a currency unit and a numéraire. In this paper, we develop a new framework for modeling financial markets, which is not based on ex‐ante choices of a currency unit and a numéraire. In particular, we introduce a “numéraire‐independent” notion of no‐arbitrage and derive its dual characterization. This yields a numéraire‐independent version of the fundamental theorem of asset pricing (FTAP). We also explain how the classic approach and other recent approaches to modeling financial markets and studying no‐arbitrage can be embedded in our framework.     

Effets des conceptions de l'erreur,de la motivation à apprendre et du soutien social sur l'intention de transférer les nouveaux apprentissages : un modèle de médiation modérée

This study aims to assess whether trainees' errors orientation can influence their motivation to learn and their intention to transfer learning. Data were collected from 275 trainees participating in a corporate training program offered by a Canadian government agency. Results show that the concept of learning by error positively influences trainees' levels of motivation and their intention to transfer learning. Results also confirm the mediating role motivation plays between the concept of learning by error and the intention of transferring learning. Finally, results confirm the moderating role of social support on the relationship between motivation to learn and the intention to transfer learning. Practical and theoretical implications of these results are discussed. Copyright © 2017 ASAC. Published by John Wiley & Sons, Ltd.     

Business Forecasting of Double‐trend Time Series: An Improved PLS‐based Time‐varying Weight Combination Approach

Business forecasting with double‐trend time series (long‐term trends and seasonal volatility) has been challenging due to its complexity. Neither a single time series model nor a fixed‐weight combination approach can fully capture the comprehensive information. We address this issue by proposing an improved partial least squares (PLS) based time‐varying weight combination approach. The proposed method can handle the relations both between the single models involved and between single models and time ordering with time‐varying weights. The test on 20 simulated datasets demonstrates the better and more robust performance of the method. We also apply it to three real datasets. The results show that our approach represents a significant improvement over the existing methods in terms of data fitness and prediction accuracy. Copyright © 2017 ASAC.

What does employee ownership effectiveness look like? The case of a Canadian‐based firm

Drawing on agency theory, we explore how 30 employees defined ownership effectiveness in a 100 % employee‐owned Canadian‐based firm. Using a qualitative case‐study, remarkable similarities were found in the factors employees themselves believed contributed most to ownership effectiveness. Despite differences in job roles, employees emphasized confidence in the ownership program, participative decision‐making, ownership identity, and their organization as a family unit. In light of these findings, we discuss how a broader conceptualization of employee ownership effectiveness can be applied for a more comprehensive understanding of how such programs may develop and manifest.

Double continuation regions for American and Swing options with negative discount rate in Lévy models

In this paper, we study perpetual American call and put options in an exponential Lévy model. We consider a negative effective discount rate that arises in a number of financial applications including stock loans and real options, where the strike price can potentially grow at a higher rate than the original discount factor. We show that in this case a double continuation region arises and we identify the two critical prices. We also generalize this result to multiple stopping problems of Swing type, that is, when successive exercise opportunities are separated by i.i.d. random refraction times. We conduct an extensive numerical analysis for the Black–Scholes model and the jump‐diffusion model with exponentially distributed jumps.     

Manufacturer Support for a Partially Integrated Channel in South Korea: Power‐dependence vs. Marketing Effectiveness Perspective

This article introduces the unique context of a partially‐integrated channel (PIC) that incorporates both market and hierarchical governance forms. In so doing, it examines determinants of the manufacturer's support for a PIC. Using power‐dependence and marketing effectiveness theories, we collected data from 172 marketing managers in charge of PICs in 15 companies in South Korea. The results showed that from the power‐dependence perspective, demand volatility, manufacturer's competitive intensity, and channel concentration are positively related to a manufacturer's dependence on the retailer, which is positively related to the manufacturer's support for the PIC with a retailer. From a marketing effectiveness perspective, channel bonding and customer linking are positively associated with manufacturer marketing effectiveness, which is an antecedent to PIC support for a retailer.

Comparing financial and social costs for top‐down versus fixed‐band selection: A practical application with bus drivers

A number of solutions have been proposed to the diversity‐validity dilemma arising from the use of cognitive ability tests in employment selection. Cognitive ability tests predict training and job performance but also produce adverse impact against minority groups. Although banding reduces adverse impact, it has been criticized for also reducing the utility of the selection process. We assessed the social and financial impact of a fixed band approach with top‐down hiring across several hiring scenarios with a pool of bus driver applicants. Overall, the fixed band approach reduced adverse impact without substantially reducing the cost effectiveness of the hiring process. We discuss the implications of these two approaches in the context of the diversity‐validity dilemma. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd.
