<p>Professor of Finance at the ESSEC Business School Paris-Singapore, Roméo Tédongap is an experienced academic expert in empirical asset pricing and portfolio choice. His primary research fields are macro-finance (investment decisions and asset valuation models based on consumption), behavioral finance (asymmetric attitude of investors towards risk in the presence of macroeconomic uncertainty), financial modeling, and econometrics (affine and regime-switching models). His skills are confirmed by several top-rated publications, notably in the Journal of Financial Economics, Review of Financial Studies, Management Science, Journal of Financial and Quantitative Analysis, Review of Finance, Journal of Econometrics, and Journal of Business and Economic Statistics. In addition, he was the co-winner of the 2013 best paper award at the European Financial Management Association (EFMA) annual meetings.</p>\n
\n
<p>Professor Tédongap’s current work focuses on asymmetric investors’ attitudes toward risk in the presence of macroeconomic uncertainty and systemic changes and their implications on asset prices and investment decisions. Systemic changes range from those caused by economic and financial crises to those resulting from climate change or events such as migrations, pandemics, etc. Related applications include evaluating ultra-long investments such as public infrastructure, climate, and energy transition. Besides, Professor Tédongap has developed a strong research interest in the attractiveness of African stock markets and their impact on economic growth and development. He also has substantial experience advising African microfinance and higher education institutions. In addition, he currently serves as associate editor of the British Accounting Review (BAR) and editorial board member of the Pan-African Scientific Research Council (PASRC).</p>\n

We find that expected returns on various asset classes reflect premiums for bearing undesirable exposures to these factors. The signs of estimated risk premiums are consistent with the theoretical predictions. Our most general, five-factor model is very successful in jointly pricing stock, option, and currency portfolios, and provides considerable improvement over nested specifications previously discussed in the literature."

Varying the skewness parameter of the HG model can restore the symmetry of IV curves.

The pattern of improvements in Delta-Hedged gains across strike prices accord with predictions from the HG model.

We rationalize these findings in an equilibrium model with recursive utility for credit default swap (CDS) spreads.

Exploiting the high-frequency information in the CDS term structure across 38 countries, we estimate the model and find parameters consistent with preference for early resolution of uncertainty. Our results confirm the existence of time-varying risk premia in sovereign spreads as compensation for exposure to common U.S. macroeconomic risk."

We derive a three-fund separation strategy: the investor allocates wealth to a risk-free asset, a standard mean-variance efficient fund, and an additional fund reflecting return asymmetries. The optimal portfolio is characterized by the investor’s endogenous effective risk aversion and implicit asymmetry aversion. In empirical applications, we find that disappointment aversion is associated with much larger asymmetry aversion than are standard preferences. Our model explains patterns in popular portfolio advice across both risk appetites and investment horizons."

Importantly, we disentangle the dynamics of conditional volatility and conditional skewness in a coherent way. Our approach allows current asset returns to be asymmetric conditional on current factors and past information, which we term contemporaneous asymmetry. Conditional skewness is an explicit combination of the conditional leverage effect and contemporaneous asymmetry. We derive analytical formulas for various return moments that are used for generalized method of moments (GMM) estimation. Applying our approach to S&P500 index daily returns and option data, we show that one- and two-factor SVS models provide a better fit for both the historical and the risk-neutral distribution of returns, compared to existing affine generalized autoregressive conditional heteroscedasticity (GARCH), and stochastic volatility with jumps (SVJ) models. Our results are not due to an overparameterization of the model: the one-factor SVS models have the same number of parameters as their one-factor GARCH competitors and less than the SVJ benchmark."

La non-normalité des rendements des actifs est capturée par un modèle normal-exponentiel multivarié ; nous développons une procédure d’estimation basée sur une méthode des moments généralisée. Les préoccupations de non-normalité des investisseurs sont introduites en ajoutant une contrainte de non-normalité linéaire à un cadre moyenne-variance par ailleurs standard. La solution du portefeuille optimal est obtenue sous forme fermée et peut être reformulée comme une stratégie de séparation à trois fonds. Des portefeuilles sous-optimaux qui ignorent la non-normalité ou sont naïfs en termes de diversification peuvent entraîner des coûts de bien-être importants mesurés par l’équivalent certain, notamment pour les investisseurs les plus tolérants au risque qui ciblent des ratios de non-normalité élevés. À l’équilibre, les rendements attendus admettent une représentation à deux bêta dans laquelle le bêta le plus important pour expliquer leur variation transversale est celui capturant la non-normalité (plus de 60 %) tandis que le bêta du MEDAF explique moins de 12 %."
"en" => "We investigate the implications of non-normality for asset allocation and pricing. Asset returns non-normality is captured through a multivariate normal-exponential model; we develop an estimation procedure based on a generalized method of moments. Investors’ non-normality concerns are introduced by adding a linear non-normality constraint to an otherwise standard mean-variance framework. The optimal portfolio solution is obtained in closed form and can be reformulated as a three-fund separation strategy. Suboptimal portfolios that ignore non-normality or are naive in terms of diversification may result in important welfare costs as measured by the certainty equivalent, notably for the most risk-tolerant investors who target large non-normality ratios. In equilibrium, expected returns admit a two-beta representation in which the most important beta in explaining their cross-sectional variation is the one capturing non-normality (more than 60%) while the CAPM beta explains less than 12%."

In contrast, our results suggest strategic trading behavior whereby some direct and indirect bidders deliberately reduce their demand in the days leading to the auction.

"en" => "Recent and growing asset pricing literature identifies downside risk factors in an economy where the representative investor has generalized disappointment aversion (GDA) preferences. We investigate and find that global GDA factors are statistically significant sources of risk in international stock markets. Nevertheless, other sources of risk, such as skewness and cokurtosis, are still relevant in the presence of global GDA factor risks. Our results survive several robustness checks. The GDA asset pricing theory is empirically validated globally as each global GDA factor risk premium estimate has the theoretically predicted sign. Furthermore, long-short portfolio strategies based on sorting countries on financial indicators such as digital payment or financial inclusion generate significantly sizeable risk premia mainly driven by their global downstate component. It is also the case when sorting countries on economic indicators such as per capita gross domestic product, ease of doing business, or country competitiveness."

We consider the impact of biofuel policies and consumers’ responses. Using Johansen cointegration and VECM, we identify two long-term equilibrium relationships that arise from biofuel policies as our first key finding. In our second insight, an asymmetric AR-EGARCH-DCC model results show heightened volatility and correlation responses to vegetable oil price deviations, especially post-biofuel. Biofuel policies significantly influence shifts in time-varying correlations among these price shocks. Finally, we examine how household consumers in nine countries respond to price shocks with a structural VAR model. The post-biofuel policy era markedly influenced consumer reactions regarding vegetable oil price fluctuations. While most nations show decreased sentiment with price hikes, China and Germany see increased consumer sentiment. South Africa’s response varies by oil type. Biofuel policies amplify these effects on consumer confidence across all studied countries. These findings have significant implications for policymakers trying to balance the energy transition and global food security while promoting sustainable growth in vegetable oil demand across both sectors and ensuring price stability for global agricultural commodities."
