The Treynor and Mazuy framework is a widely used return-based model of market timing, but existing corrections of the regression intercept can be manipulated through derivatives trading. We propose an adjustment based on Merton's option replication approach. The linear and quadratic coefficients of the regression are exploited to assess the cost of the replicating option that yields similar convexity for a passive portfolio. A similar reasoning applies for various timing patterns and in multi-factor models. Our empirical application shows that, unlike existing performance adjustment methods, the portfolio replication approach uncovers a positive link between the convexity and the performance of market timing funds.

This paper studies the joint impact of smoothing and fat tails on the risk-return properties of hedge fund strategies. First, we adjust risk and performance measures for illiquidity and the non-Gaussian distribution of hedge funds returns. We use two risk metrics: the Modified Value-at-Risk and a preference-based measure retrieved from the linear-exponential utility function. Second, we revisit the hedge fund diversification effect with these adjustments for illiquidity. Our results report similar fund performance rankings and optimal hedge fund strategy allocations for both adjusted metrics. We also show that the benefits of hedge funds in portfolio diversification are still persistent but tend to weaken after the adjustment for illiquidity. [less ▲]

In this paper, we examine the opportunity to create a Central Agency of European Debt (CAED) to improve the coordination between the issuances of sovereign debt in the EMU, by allowing the Agency to issue euro – bonds and determine the optimal proportion of foreign currency denominated debt and the corresponding maturity at the EMU level. We argue that this Agency could decrease both the overall cost of sovereign debt at the EMU level and the cost of sovereign debt of the individual EMU countries, including the strongest members (Germany, the Netherlands). Such a mechanism requires four economic conditions: a collective guarantee by members for the euro-bonds, a marking-to-market process for each individual member, a seniority of existing sovereign debt, and an internal sovereign swap market between the members of this Agency.

The performance of a market timer can be measured through the Treynor and Mazuy (1966) model, provided the regression alpha is properly adjusted by using the cost of an option-based replicating portfolio, as shown by Hübner (2010). We adapt this approach to the case of multi-factor models with positive, negative or neutral betas. This new approach is applied on a sample of hedge funds whose managers are likely to exhibit market timing skills. We stick to funds that post weekly returns, and analyze three hedge funds strategies in particular: long-short equity, managed futures, and funds of hedge funds. We analyze a particular period during which the managers of these funds are likely to magnify their presumed skills, namely around the financial and banking crisis of 2008. Some funds adopt a positive convexity as a response to the US market index, while others have a concave sensitivity to the returns of an emerging market index. Thus, we identify “positive”, “mixed” and “negative” market timers. A number of signs indicate that only positive market timers manage to acquire options below their cost, and deliver economic significant performance, even in the midst of the financial crisis. Negative market timers, by contrast, behave as if they were forced to sell options without getting the associated premium. We interpret this behavior as a possible result of fire sales, leading them to liquidate positions under the pressure of redemption orders, and inducing negative performance adjusted for market timing.

Using a unique database of 990 VC-backed Belgian firms, we study whether compatibility between corporate and environmental characteristics matters. We address two questions: (i) Does the interplay of company, industry, and product factors affect the expected returns of the VC-backed firms? (ii) Does the joint compatibility between these factors results in a non-linear increase in performance? Panel data analysis shows a significant influence of factor compatibility on returns. Quantile regression analysis indicates a non-linear relationship between the return and its determinants. Conjoint analysis identifies certain combinations of factors, which collapse into classifiable patterns described in the strategic management literature. [less ▲]

Convertible debt eliminates asset substitution in a one-period setting (Green, 1984). But convertible debt terms are usually set before the asset substitution opportunity. This allows shareholders and convertible debtholders to play a strategic noncooperative game. Two risk-shifting Nash equilibria are attainable: pure asset substitution when, despite no conversion, shareholders benefit from shifting risk, and strategic conversion when, despite early conversion, convertible debtholders expropriate wealth from straight debtholders. Even when initial convertible debt is designed to minimize the risk-shifting likelihood, the risk of asset substitution remains economically substantial — contrasting with the agency theoretic rationale for issuing convertible debt.

This paper studies sovereign credit spreads using a contingent claims model and a balance sheet representation of the sovereign economy. Analytical formulae for domestic and external debt values as well as for the financial guarantee are derived in a framework where recovery rate is endogenously determined as the solution of a strategic bargaining game. The approach allows to relate sovereign credit spreads to observable macroeconomic factors, and in particular accounts for contagion effects through the corporate and banking sectors. Pricing performance as well as predictions about credit spread determinants are successfully tested on the Brazilian economy. [less ▲]

This paper studies the contracting choices between an entrepreneur and venture capital investors in a portfolio context. We rely on the mean-variance framework and derive the optimal choices for an entrepreneur with and without the presence of different kinds of venture capitalists. In particular, we show that the entrepreneur always has the incentive to share the risk and benefits of the venture whenever possible. On the basis of their objectives and characteristics, we distinguish the situations of the corporate, independent, and bank-sponsored venture capital funds. Our framework enables us to derive the optimal contract design for the entrepreneur, featuring the choice of investor, the entrepreneur's investment in the venture, and her dilution in the project's equity as a function of her bargaining power. This result allows us to characterize the choice of the investor depending on her cost of equity and debt capital. In addition to project size and risk, entrepreneur's risk aversion turns out to be a critical determinant of VC investor choice -- a finding which is strongly supported by a panel analysis of VC fund flows for 5 European countries over the 2002--2009 period.
