My team and I have just had our research accepted into the International Journal of Production Economics after several rigorous reviews and revisions – published as Wood, Wang, Olesen, and Reiners (2017). The article is titled: The effect of slack, diversification, and time to recall on stock market reaction to toy recalls
In this work, we used event study methodology, which has been used in the Operations Management literature to study demand-supply mismatches (Hendricks & Singhal, 2009), medical device recalls (Thirumalai & Sinha, 2011), product introduction delays (Hendricks & Singhal, 2008), and food recalls (Salin & Hooker, 2001) among other topics. The calculations gave us an abnormal return value for each event that we then used in a cross-sectional regression to test a series of hypotheses that relate to the operational decisions that managers can make. Specifically, we were looking at geographic and business diversification; financial, inventory, and capacity slack; how long a product is on the market for before it is recalled; and whether reactions to the recalls change appreciably over time.
Past toy recalls have led to an increase in consumer concerns while toy manufacturers and retailers increasingly outsource and create longer supply chains, making it more challenging for them to ensure toy safety. This article examines firms making toy recall announcements to assess the impact operational characteristics have on the negative stock market reaction to the announcement. 135 toy recall announcements in the U.S. from 1979 to 2016 were analyzed using event study and cross-sectional regression. While a toy recall announcement results in a negative stock market reaction, our results show that greater levels of business diversification, inventory slack, and a longer time to recall are all associated with a less negative stock market reaction. In contrast, greater capacity slack is associated with a more negative stock market reaction. We find no evidence that geographic diversification or financial slack influences the stock market reaction, nor have reactions changed appreciably over time. This article contributes to the product harm and product recall literature by focusing on these operational elements. Managers should be aware of the benefits of greater slack and business diversification while planning their business, and the impact of a longer time to recall.
