Program

Week 1: CSR from a Corporate Finance and Asset Pricing Perspective

The relationship between firms and markets in an ESG framework highlights a fundamental shift. Traditional corporate finance focuses on profit maximization for shareholders, while CSR and ESG integration reorient firms toward stakeholder risk minimization. This shift not only changes corporate strategy, but also affects how markets price information, leading to the emergence of an ESG systematic risk factor in asset pricing. Recent studies show that CSR influences market performance, firm valuation, and risk-adjusted returns by reducing idiosyncratic risk, increasing resilience in crises, and lowering funding costs.

Week 2: Socially Responsible Investment (SRI)

Socially Responsible Investment (SRI) involves integrating ESG factors into investment strategies. Research suggests that SRI funds can perform similarly to conventional funds, and their risk-return profile is often comparable or even superior. Moreover, SRI investments are increasingly attractive to a growing class of socially conscious investors.

Week 3: ESG Market Equilibrium

The market equilibrium for ESG-related investments arises from the interaction between demand and supply. On the supply side, firm commitment to CSR translates into ESG compliance levels that influence expected cash flows, risk, and funding costs; on the demand side, SRI preferences, ownership, and flows shape investor clienteles and quoted prices. Their interaction sets the equilibrium price of ESG-related securities and can widen or narrow the wedge between fundamental value and market quotes. Building on empirical evidence that both forces matter in the SRI space.

Week 4: Systematic ESG Risk Factor

Incorporating ESG factors into asset pricing models captures the systematic risks associated with the shift from profit maximization to stakeholder risk minimization. Building on the theoretical foundations of the first three weeks --- the firm-side supply of ESG compliance (Week I), the role of SRI demand (Week II), and the interaction of the two in shaping market equilibrium (Week III) --- the identification of a systematic ESG risk factor emerges as a natural consequence. Extending standard frameworks such as CAPM and Fama--French with an ESG-mimicking factor links firm compliance (supply) and investor preferences (demand) to expected returns. This approach enables testing both time-series and cross-sectional predictions, assessing interactions with size, value, and momentum factors, and distinguishing risk-driven premia from flow-driven effects through orthogonalization and robustness checks. The result is a clearer view of how ESG influences market risk, expected returns, and the relationship between fundamental and quoted prices.

Week 5: SR Mutual Funds and Portfolio Perspective

Mutual funds with an SR focus represent the portfolio-level extension of ESG investing. Just as firms differ in their level of ESG compliance (Week I) and investors channel demand through SRI preferences (Week II), funds aggregate these choices into diversified portfolios. An SR fund is essentially a weighted average of firm-level ESG compliance, where stock selection, screening, and tilting determine the fund’s ESG profile. This makes mutual funds a natural laboratory to study the transmission of ESG from the firm-level to the portfolio equilibrium, and to analyze the transition from systematic ESG risk (priced at the single-asset level, Week IV) to systemic ESG risk (arising through common holdings, flows, and network externalities across funds). Empirical evidence shows that SR focused funds display distinct risk–return profiles compared to conventional funds: they may face reduced diversification or lower traditional premia, but also exhibit greater resilience in crises and better alignment with social objectives. This dual perspective emphasizes how ESG affects not only firm valuation and factor models, but also the stability and performance of the financial system through investment vehicles used by end investors.

Week 6: CO2 Emissions and Portfolio Management

One of the key issues within SRI is the role of carbon emissions in portfolio management. At the stock level, the literature documents a carbon premium: firms with higher emission intensity (brown stocks) earn higher excess returns, reflecting both systematic risk (e.g., regulatory and transition costs) and investor preferences (exclusion of polluting firms). At the mutual fund level, recent studies show that funds differ in their exposure to carbon risk, but do not fully diversify it. As a result, carbon emissions remain priced in fund returns. This highlights the dual relevance of CO2 risk: as a dimension of sustainable investment objectives and as a systematic factor influencing portfolio performance and financial stability.

Teaching methods

Theoretical lectures by the professor.

Practice sessions where students present their ongoing work and engage in discussions with their peers under the instructor supervision.

Exam Rules

Class participation (30%): evaluation of weekly work on the slide presentation.

Final oral exam (70%): students present and discuss the topic of their expanded slide presentation in public speech + Data Results (15 slides). Student are only allowed to sit the exam twice. The grade of the resit will be registered (included a mark of "fail"). Students present their chosen topic and their data results in a public presentation, supported by 15 slides divided into five sections (research idea, literature, data and estimation dataset, results, and conclusions).Students are allowed to take the exam only twice. It is not possible to retake the exam twice in the same session. The grade from a repeated exam attempt will be recorded, including a possible "fail" grade.

All students are actively involved in the learning process throughout the course weeks. During the weekly exercises (and while preparing the slide presentation and data analysis as a weekly take-home, TH), they are required to comment on their peers' presentations. The preparation of the presentation at home is based on the student’s chosen topic and follows a weekly schedule. By the end of the six weeks, all parts of the concise presentation will have been covered by the student, ensuring that each student is prepared to take the final exam and demonstrate their learning outcomes.


The criteria to formulate the final grade expressed in 30 over 30 are the following

- Fail: significant inaccuracies in knowledge and in understanding topics; limited analysis and synthesis skills, frequent generalizations.

- 18-20: sufficient knowledge and understanding of topics with some lacks; sufficient analysis, synthesis, and independent judgment skills.

- 21-23: standard knowledge and understanding of topics; pritty correct analysis and synthesis skills with coherent logical argumentation.

- 24-26: good knowledge and understanding of topics; good analysis and synthesis skills with rigorous argumentation and approach.

- 27-29: comprehensive knowledge and understanding of topics; remarkable analysis and synthesis skills. Good and independent judgment.

- 30-30L: excellent level of knowledge and understanding of topics. Remarkable analysis, synthesis, and independent level of judgment skills. Arguments expressed in original way.
