Objectives
THE STOCHASTIC FINANCE COURSE, IN LINE WITH THE CORE OBJECTIVES OF THE DEGREE PROGRAM, IS DEDICATED TO THE ANALYSIS AND APPLICATION OF MATHEMATICAL MODELS USED IN FINANCE WHEN THE STOCHASTIC ELEMENT BECOMES PART OF THE QUANTITATIVE DESCRIPTION. IN PARTICULAR, STUDENTS WILL ACQUIRE THE TOOLS OF STOCHASTIC COMPUTATION AND COMPUTER IMPLEMENTATION NECESSARY TO SOLVE COMPLEX PROBLEMS RELATED TO THE FINANCIAL SECTOR. THE TEACHING FINALIZES THE FORMAL RIGOR TO AN APPLICATIVE PERSPECTIVE, EMPHASIZING THE CRITICAL DISCUSSION OF THE RESULTS.
KNOWLEDGE AND UNDERSTANDING
STUDENTS WILL LEARN HOW TO DEAL WITH THE STOCHASTIC ELEMENT AS A TOOL OF CONCRETE UTILITY DUE TO THE INCREASED INFORMATION CONTENT THAT A STOCHASTIC MODEL OFFERS TO THE ANALYST, COMPARED TO A DETERMINISTIC APPROACH. COMPUTER APPLICATIONS WILL PROVIDE STUDENTS WITH THE TOOLS TO PROCEED WITH ANALYSIS, ESTIMATES, FORECASTS, RELATED TO THE PROCESSES OF FINANCIAL QUANTITIES AND HUMAN SURVIVAL, THIS LAST FUNDAMENTAL IN THE FINANCIAL ANALYSIS OF LIFE INSURANCE CONTRACTS.
IN SUMMARY, THE CORNERSTONES OF THE COURSE WILL CONSIST OF THE FOLLOWING POINTS:
•INCLUSION OF THE STOCHASTIC ELEMENT IN THE FINANCIAL HYPOTHESES
•THE FUNDAMENTAL ASSUMPTIONS TO DESCRIBE A STOCHASTIC PROCESS USEFUL IN FINANCE
•THE DIFFERENTIAL APPROACH TO UNDERSTAND THE DYNAMICS OF THE DESCRIPTION OF A RANDOM QUANTITY
•THE INTEREST RATE: THE DESCRIPTIONS OF ITS TREND AND ITS IMPACT THROUGH PROCESSES, THEOREMS AND EQUATIONS.
•USE OF R SOFTWARE IN STOCHASTIC FINANCE: A WAY TO AMPLIFY THE SCOPE AND THE RANGE OF THE RESULTS OBTAINABLE
•ESTIMATION AND SIMULATIONS OF RATE TERM STRUCTURE
•SURVIVAL ANALYSIS: SPECIALIZED SOFTWARE AND PROJECTIONS FOR THE DESCRIPTION OF SURVIVAL TRENDS, FUNDAMENTAL FOR THE MANAGEMENT OF LIFE INSURANCE PORTFOLIOS.
ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING
STUDENTS WILL ACQUIRE ANALYTICAL AND CRITICAL SKILLS THAT WILL ENABLE THEM TO:
•THE HISTORICAL CONSTRUCTION AND PROJECTION OF INTEREST RATE TERM STRUCTURES IN SPECIFIED FINANCIAL MARKETS
•THE HISTORICAL CONSTRUCTION AND PROJECTION OF SURVIVAL
•THE PRICING OF FINANCIAL DERIVATIVES AND THE DEVELOPMENT OF OPERATIONAL STRATEGIES
TRANSVERSAL SKILLS
STUDENTS WILL ACQUIRE ANALYTICAL AND CRITICAL SKILLS THAT WILL ENABLE THEM TO:
•DESCRIBE THE BEHAVIOR OF FINANCIAL QUANTITIES IN THE PAST BEHAVIOR AND ELABORATE FORECASTS ON THEIR FUTURE EVOLUTION
•ABILITY TO SYNTHESIZE THE IMPACT OF UNCERTAINTY WITH QUANTITATIVE INDICATORS
•STRUCTURE MATHEMATICAL DESCRIPTIONS FOR CONTRACTS DEPENDENT ON THE INTEREST RATE
•CONFIDENTLY USE SPECIALIZED FINANCIAL SOFTWARE
Prerequisites
COURSES IN MATHEMATICAL METHODS FOR ECONOMICS, FINANCIAL MATHEMATICS (I MODULE OF THE QUANTITATIVE METHODS COURSE) AND STATISTICS ARE RECOMMENDED.

PACKAGES: DEMOGRAPHY, STMOMO, LIFECONTINGENCIES. PROJECTIONS WITH LEE CARTER MODEL AND EXTENSIONS, CBD MODEL AND EXTENSIONS (10 HOURS EMPIRICAL APPLICATIONS IN THE LABORATORY).
THE DETAILED COURSE SCHEDULE IS AVAILABLE ON THE TEACHERS’ WEBSITE.

Teaching Methods
THE COURSE OF STOCHASTIC FINANCE CONSISTS OF 60 HOURS OF DIDACTICS, 30 OF WHICH WILL BE IN A COMPUTER LAB. THE LECTURES WILL BE FRONTAL AND CARRIED OUT WITH CONSTANT ATTENTION TO THE THEORETICAL APPROACH OF THE TOPICS, TO THE APPLICATIONS AND THE INTERPRETATION OF THE RESULTS OBTAINED.
Verification of learning
THE VERIFICATION OF LEARNING IS ORIENTED TO STIMULATE THE STUDY AND UNDERSTANDING OF THE TOPICS COVERED DURING THE COURSE BY THE STUDENTS, WITH PARTICULAR ATTENTION TO THE ABILITY TO APPLY THE MODELS TO CONCRETE SITUATIONS.
MODULE I: THE STUDENT'S FINAL ASSESSMENT WILL CONSIST OF A WRITTEN AND AN ORAL TEST. THE MODULE WILL BE CONSIDERED PASSED IF BOTH THE WRITTEN TEST AND THE ORAL TEST WILL HAVE OBTAINED AN EVALUATION AT LEAST SUFFICIENT (GREATER THAN OR EQUAL TO 18/30). IN ADDITION TO THE SESSIONS SCHEDULED IN THE CALENDAR, THERE WILL BE A WRITTEN AND ORAL TEST AT THE END OF THE MODULE.
EACH TEST WILL BE GRADED IN THIRTIETHS AND THE FINAL GRADE WILL BE THE AVERAGE OF THE GRADES OBTAINED ON THE TWO TESTS. THE MAXIMUM GRADE IS 30/30 WITH HONORS.
THE WRITTEN TEST WILL HAVE A STRONG APPLICATIVE AND PRACTICAL CHARACTERIZATION. THE ORAL TEST WILL BE OF THEORETICAL CHARACTER.
MODULE II: THE FINAL EXAM CONSISTS OF A PROJECT WORK TO BE PRESENTED IN THE FORM OF A WRITTEN PAPER AND TO BE DISCUSSED ORALLY. THE EVALUATION IS MADE IN THIRTIETHS AND IS SUFFICIENT IF PASSED WITH AT LEAST 18/30. THE MAXIMUM GRADE IS 30/30 WITH HONORS.
THIS WORK WILL BE ORIENTED TO VERIFY THE ABILITY TO IMPLEMENT THE TOOLS ACQUIRED DURING THE MODULE, IN THE CONTEXT OF A APPLICATIVE CASE TO BE SOLVED.
THE FINAL EVALUATION IN THE WHOLE EXAM WILL BE THE AVERAGE OF THE EVALUATIONS REPORTED IN EACH OF THE TWO MODULES.
