What information belongs in a warning?

A general approach is described for determining the information content of warnings. It begins with a formal analysis of the magnitudes of the risks arising from misuse (or even from proper use) of a product. It proceeds with structured, open-ended interviews intended to elicit consumers' naive conceptualizations of the processes creating and controlling those risks. Communications are then focused on information filling the most consequential gaps in their knowledge. The implementation of those warnings will depend on the extent of the knowledge gaps, and the opportunities for closing them. This approach allows for an estimate of the residual problems to be expected, if a warning program is implemented. It can also help to focus the policy debate over whether a product warning will achieve an acceptable level of misunderstanding. © 1998 John Wiley & Sons, Inc.     

Technology in the time of corona: A critical institutional reading

Drawing on institutional theory and using examples from Israel, we offer a critique of technology's deployment in responses to the coronavirus disease (COVID-19). We distinguish between technologies-in-use (“small ‘t' technologies”), the bundle of artifacts and practices that bring them into being, and “Big ‘T' Technology,” the latter being technology as an institution – shared meanings, structures, and practices that govern thought and action. Using the conceptual tool kit of institutional theory, we make three interrelated arguments. First, the deployment of technologies-in-use in response to the pandemic is embedded in diverse and contradictory institutions, the institution of technology among them. These technologies participate in the very construction of crisis, which fosters the revert to known and established ways of being and doing. Thus, technologies-in-use are not necessarily the most efficient and rational but rather the most legitimate and readily available. Second, putting certain technologies into action has not been happening by itself. Instead, we have witnessed contestations among relevant agents – like politicians and experts – who engage in institutional work to serve their interests. Third, despite its global reach, technology is locally adapted and implemented in specific contexts. All in all, institutional theory helps us to explore further and critique the naïve belief, common in public discourse, in technology as a remedy of all things. Instead, it offers a more critical understanding of the cultural dynamics involved in putting technology to work in the coronavirus crisis. This critical lens carries implications for policymaking and implementation in times of crisis.     

Penetrating the Book-to-Market Black Box: The R&D Effect

The book-to-market (BM) phenomenon – the positive association between BM and subsequent returns – looms large among capital market enigmas. Economic theory postulates that the difference between market and book values of companies reflects their future abnormal profits. We capture these abnormal profits for a large sample of science-based companies by estimating the value of the off-balance sheet investment generating those profits – the value of R&D capital – and show empirically: (i) Firms' R&D capital is associated with their subsequent stock returns. (ii) For R&D intensive firms, this 'R&D effect' subsumes the 'book-to-market effect.' (iii) The association between R&D and subsequent returns appears to result from an extra-market risk factor inherent in R&D, rather than from stock mispricing. We thus provide an explanation for the book-to-market phenomenon of R&D companies.     

Does corporate ownership structure affect its strategy towards diversification?

We claim that there is a link between corporate control structure and managers’ strategy towards unrelated mergers and risk diversification. Companies with greater ownership concentration are less diversified. Evidence also shows that corporate diversification generally results in value loss while focussing is value increasing. This highlights the potentially detrimental effect of agency problems on corporate strategy. Copyright © 1999 John Wiley & Sons, Ltd.     

Sabotaging in contests with monitoring efforts

This paper considers a 3‐stage contest with both sabotage and monitoring efforts that aim to reduce sabotage. In the first stage, the regulator sets his monitoring efforts for each contestant. In the second stage, each contestant determines his sabotaging efforts, based on the monitoring efforts that were imposed by the regulator. In the third stage, each contestant determines his productive efforts in the contest. The results supply a justification to exert monitoring efforts because these efforts may benefit both the contestants and the regulator (a win‐win situation). Furthermore, the paper defines the conditions where exerting monitoring efforts would be worthwhile.

Perceived crisis management and its effect on re-election: the case of local government in Israel under the Second Lebanon War

The performance of local authority heads in times of emergency is a topic that has apparently received very little attention in the research literature. The same is true with regards to the relationship between performance and re-election chances in crisis situations. The hybrid macro polity view makes it possible to ‘pit’ the rational school of objective performance against the bounded rationality school of perceived performance. We examine which of the two is better at explaining the replacement or re-election of the incumbent local authority head in 17 local authorities in the North of Israel, after the Second Lebanon War. In the “Beauty Queen” contest between perceived and objective performance, the perceived performance appears to be a clear winner.     

The Mispricing of Cash Flows and Accruals at Different Life‐Cycle Stages

This paper employs the firm life‐cycle concept to extend our understanding of the mispricing of accrual and cash flow information by the stock market. We find that accruals and free cash flows are strongly (negatively) correlated in the maturity and decline stages of a firm's life cycle but not in the growth stage, suggesting that they capture unique information in the growth stage of the firm's life cycle but more correlated information in the later stages. Consistent with this finding, we show that the cash flows anomaly subsumes the accruals anomaly in maturity and decline stages, but not in the growth stage. Our findings contribute to the debate regarding the overlap between the two anomalies.
