This paper wants to analyse the cyber-risk impact on economy in particular on the returns of the companies suffering information braches. The problem has become very interesting in recent years in the literature for the large dependence of the business with cyber world. The analysis focuses on event study in which the impact of cyber-attacks on stock prices of selected companies is investigated. Cyber-risk phenomenon is processed considering a portfolio of targeted assets, in order to analyse their correlation. Risk measures, such as VaR, will be evaluated and backtested using different methods to monitor which one is able to better capture this type of riskiness.
Climate change can deeply impact a company’s business performance, therefore insurance is an important tool to mediate such a risk, helping firms to remain on the market. Polluting companies want to maximize profits according to different business strategies and that appeal to their risk attitude. Firms are Nash players in an oligopoly market adopting two production technologies, brown or green. Climate change loss is a function of the firms’ emissions and is considered endogenous in the maximization problem of the players. We study firms’ behavior in choosing their more profitable strategy through a random matching evolutionary context. Analysis of the model reveals that the dynamic system admits at most seven stationary states. The paper focuses on the regime in which all the possible strategies coexist, due to its economic relevance. Moreover, the results of the sensitivity analysis show interesting policies to nudge an ecological transition.
This study complies with the reorganization of health care provider processes based on the cost of life cycle of the product. The aim is to determine the costs of treatment administration of extracorporeal dialysis and other treatments in extracorporeal systems. The strategy here was to apply for the first time the "bill of material" (BoM) method to the production and management of the services above. By using standard replacement flows, we build the "bill of materials" to calculate the cost of a CRRT (continuous renal replacement therapy) with anticoagulant. The standard cost of the process is thus obtained. The method here developed can be used for accounting purposes and for economic planning, as a tool for accurate statistical evaluation of medical care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
