Product-harm crises are among a firms worst nightmares. Since marketing investments may be instrumental to convince consumers to purchase the firm&apos's products again, it is important to provide an adequate measurement of the effectiveness of these investments, especially after the crisis. We provide a methodology through which firms can assess the impact of product crises in a quantitative way. Based on the model estimates, firms can estimate the required level of investment to recoup from the crisis. A key finding of this paper is that it is not only important to assess the extent to which business is lost as a result of the crisis, but also to find the new, postcrisis response parameters to marketing activities. The study of an Australian product-harm crisis for peanut butter reveals that a product crisis may represent a quadruple jeopardy for a firm: (i) loss of baseline sales, (ii) a reduced own effectiveness for its marketing instruments, (iii) increased vulnerability, and (iv) decreased clout. We arrive at this conclusion by using a time-varying error-correction model that allows for (i) shortand long-term marketing mix effects, (ii) intercepts and response parameters that change over time as a result of the crisis, and (iii) missing observations, which result from the absence of the impacted brands during the product-recall period. The time-varying error-correction model is applicable to other marketing-research areas in which these three requirements (or any subset thereof) apply.
