This study examines the relationships between macroeconomic factors and stock prices in Cyprus. Estimating a reduced form Vector Autoregressive model (VAR) we determine Granger causality between stock returns and the predictor variables. We find strong evidence of predictability (which implies inefficiency) in stock returns, which is similar to the pattern observed in developed stock markets. In common with prior studies in this area, we cannot use our results as evidence of market inefficiency or deficiencies in the asset-pricing model.
Vulnerability prediction facilitates the development of secure software, as it enables the identification and mitigation of security risks early enough in the software development lifecycle. Although several factors have been studied for their ability to indicate software security risk, very limited attention has been given to technical debt (TD), despite its potential relevance to software security. To this end, in the present study, we investigate the ability of common TD indicators to indicate security risks in software products, both at project-level and at class-level of granularity. Our findings suggest that TD indicators may potentially act as security indicators as well.
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.
