Using time series models and analyses, millions of transactions, unstructured and semi-structured data can be searched to spot patterns and detect abnormalities and irregularities. The emergence of Big Data and data science creates an opportunity to further investigate the application of time series models in business using financial information and non-financial sustainability information of environmental, social, and governance performance. The ever-increasing business complexity, challenges brought on by the global COVID-19 pandemic, along with the growing demand for high-quality financial and non-financial information, require the use of time series analyses to improve the financial reporting process. Much of information is now available social media, e-mail, audio, video, and text files and the time series analyses can be used to examine such information. The primary purposes of this presentation are to: Discuss the relevance and use of time series analyses for Big Data and data science. Present how time series models can be efficiently and effectively applied in business analytics Explore the application of time series analyses in business research by discussing the differences among correlation, association, and Granger causality and providing insight into their proper use in the sustainability literature. Discuss policy, practical, educational, and research implications of time series analyses. Present the use of time series analyses by businesses and management in their predictive models of managerial strategies, decisions, and actions. Discuss, integration of time series analyses into the curricula of business schools and accounting programs. Present the use of time series models to transform unstructured and semi-structured data into structured information in improving the quality of financial and non-financial information. Discuss application of time series analyses in advancing business sustainability by presenting an example of the integrated Big Data and time series analyses into environmental, social and governance dimensions of business sustainability.
