Moments structure of ? 1-stochastic volatility models

We consider Taylor??s stochastic volatility model (SVM) when the innovations of the hidden log-volatility process have a Laplace distribution (? ₁ exponential density), rather than the standard Gaussian distribution (? ₂) usually employed. Recently many investigations have employed ? ₁ metric to allow better modeling of the abrupt changes of regime observed in financial time series. However, the estimation of SVM is known to be difficult because it is a non-linear with an hidden markov process. Moreover, an additional difficulty yielded by the use of ? ₁ metric is the not differentiability of the likelihood function. An alternative consists in using a generalized or efficient method-of-moments (GMM/EMM) estimation. For this purpose, we derive here the moments and autocovariance function of such ? ₁-based stochastic volatility models.     

Selecting Board Members: The Impact of Common Knowledge on Gender Diversity – An Experimental Investigation

Using a corporate governance experiment, we explore the role of common knowledge of diversity on board members' selection. Our results show that common knowledge of diversity impacts significantly and negatively the proportion of women selected on boards and in a higher proportion in sectors perceived as ‘masculine’. We also bring evidence of an order effect that makes the selection of men on boards likelier for the first chosen members. This bias is stronger for male decision makers. This article provides implications and directions for future research for the understanding of decision making involved in the selection process for board members.

One-Shot Public Mediated Talk

We show that any correlation device with rational coefficients can be generated by a mechanism, where each player sends a private message to a mediator who in turn makes a public deterministic announcement. It is then shown that the mechanism can be adapted also to situations with differential information, where the correlation device itself depends on the players' private messages that may vary with their realized types. All the mechanisms suggested are immunized against individual deviations. Therefore, by using them, players can implement any correlated or communication equilibrium.Journal of Economic LiteratureClassification Number: C72.     

Canadian Evidence on the Constructive Capitalization of Operating Leases*

One type of relevant ex ante research supporting the accounting standard‐setting process is the study of a proposed standard's impact on reported figures. The International Accounting Standards Board recently decided to review the lease accounting standard, which will naturally involve consideration of the G4 + 1 recommendation to capitalize all noncancellable lease contracts, including operating leases. National evidence of the impact of the G4 + 1 proposals provides feedback for the international standard‐setter. This study developed and used a refined constructive capitalization method, in which company‐specific assumptions — interest rate, total/expired/remaining lives of leased assets, and tax rate — were used to compute the impact of operating‐lease capitalization on key financial indicators for a sample of Canadian public companies. The results indicate that capitalizing operating leases would lead to the recognition of important additional assets and liabilities on the balance sheet. It would therefore significantly increase the debt‐to‐asset ratio and significantly decrease the current ratio. These results were noted across all industry segments in the sample. Income statement effects were generally less material. Significant impacts on return on assets, return on equity, and / or earnings per share were noted in only three industry segments: merchandising and lodging, oil and gas, and financial services. Intercompany comparability would not be affected overall nor within industries, because of similar rankings for each financial indicator before and after operating‐lease capitalization.     

The effects of document language quality on consumer perceptions and intentions

This article establishes a link between language quality in the documentation accompanying a product and consumers' evaluations of, and behavioural intentions towards, both the product and the manufacturer. In a laboratory experiment, 116 participants assembled a product using assembly guides with different language quality levels. Results show that language quality affects document evaluation, which spills over to the evaluations of both the product and the manufacturer. Findings also indicate that the documentation accompanying a product is a vital extrinsic cue used by consumers to evaluate both the product and the manufacturer, which implies that these documents are secondary products that add value to the primary product. Theoretical and managerial implications of these findings are discussed. Copyright © 2010 ASAC. Published by John Wiley & Sons, Ltd.

Food Recalls and Risk Perception: An Exploratory Case of the XL Foods and the Biggest Food Recall in Canadian History

The recall that plagued Canada’s XL Foods in 2012, tied to E. coli cases found in ground beef, was the largest food recall in Canadian history. As a result of the outbreak, 18 consumers allegedly became ill and XL Foods launched a voluntary recall of all packaged meats from the plant, and the plant underwent intense sanitation for weeks. This study aims to understand how the incident affected consumer confidence in the safety of ground beef. Unlike other food processors, XL Foods does not own and manage brands. XL Foods are sold under brands owned by food distributors and retailers in Canada and the United States. A survey was conducted months after the recall to assess long-term implications. Results suggest consumers still trust the safety of ground beef. Results of this research will also further foster understanding consequences of recalls for food marketing and its effects on consumer behavior.     

Depreciation in the Canadian Airline Industry

This case is designed to help students enhance their analytical skills and link accounting policy choices with corporate strategy. Written initially for MBA students and senior analysts attending executive education sessions, it provides participants with 1) industry background for the Canadian airline sector, and 2) historical and selected financial and non‐financial information from the annual reports and initial public offering documents of three players in this industry. Participants are invited to reflect on the theoretical and practical reasons underlying the choice of a depreciation method by airline companies, to find ways to quantitatively compare companies that use different depreciation methods, and to link these policy choices to possible strategic considerations. This case is based on a unique situation prevailing in 2009 where financial information was available for all three airlines which were using different approaches for aircraft depreciation.
