**Preface to "Fuzzy Sets in Business Management, Finance, and Economics"**

Since the publication of Lotfi A. Zadeh's seminal paper "Fuzzy Sets" in 1965 in the journal Information and Control, there has been constant growth in theoretical developments and in the practical application of Fuzzy Set Theory and related mathematical tools. These tools have been applied widely, both by industry and academic research, to decision making and economics due to their versatility. On the one hand, they can efficiently represent and handle uncertain and vague information such as subjective judgements, non-precise observations on variables, or ill-defined relations between variables. On the other hand, they make implementing computations or identifying patterns in data much easier. To do so, Fuzzy Set Theory provides a vareity of mathematical techniques in fields such as Expert Systems, Soft Computing, Data Analysis, Mathematical Programming, and Multiple Criteria Decision Making. Business management, decision making, or actuarial modelling are some examples of practical applications in these fields. This Special Issue provided a platform for researchers from academia and industry to present novel work in the domain of applied developments for Fuzzy Sets and in methodologies related to business, financial, and economic analysis. We hope that these results will help to foster future research in the fields of economics and in the social sciences.
