Currency risk hedging: Futures vs. forward

Journal of Banking & Finance 1998 22(1), 61-81
The objective of this paper is to address the issue of choosing between currency forward and currency futures contracts when hedging against currency risk within a stochastic interest rates environment. We compare between the hedging effectiveness of the two derivative assets both within a narrow sense (i.e., volatility minimization) and within a wide sense (i.e., risk-return trade-off). When judging hedging effectiveness in the narrow sense, forward and futures contracts give identical results even if they do not have identical prices. When judging hedging effectiveness in the wide sense, the choice between the two contracts is determined by the correlation between the domestic and the foreign term structures dynamics.

Interest Rate Risk and the Cross Section of Stock Returns

Journal of Financial and Quantitative Analysis 2014 49(2), 483-511
We derive a macroeconomic asset pricing model in which the key factor is the opportunity cost of money. The model explains well the cross section of stock returns in addition to the excess market return. The interest rate factor is priced and seems to drive most of the explanatory power of the model. In this model, both value stocks and past long-term losers enjoy higher average (excess) returns because they have higher interest rate risk than growth/past winner stocks. The model significantly outperforms the nested models (capital asset pricing model (CAPM) and consumption CAPM (CCAPM)) and compares favorably with alternative macroeconomic models.

Chasing the ESG factor

Journal of Banking & Finance 2022 139, 106498
We analytically compare two dominant methodologies for the construction of an ESG factor: the time-series (ratings used to sort stocks) and cross-sectional (ratings used to weight stocks) approaches. Differences in ESG rating and exposure to other firm characteristics imply an ex ante expected return spread between the two factors. We construct a cross-sectional factor (i) featuring a targeted rating, thus allowing comparability with other factors, (ii) neutralizing exposure to other firm characteristics, and (iii) not harming diversification through stock screening. Using ratings from several data vendors, we document strong variations of the factor alpha in the time series and across vendors. The conditional alpha is negatively related to the level of media attention for ESG and positively related to variations in media attention.

General equilibrium pricing of CPI derivatives

Journal of Banking & Finance 2005 29(5), 1265-1294
We examine the issue of pricing forward futures and option contracts written on the Consumer Price Index (CPI), the change of which is a measure of inflation affecting the economy. Traditional approaches postulate an exogenous process for the price level and then derive CPI derivatives prices by standard arbitrage arguments. By contrast, we build the general equilibrium of a continuous time monetary economy that is affected by both real and nominal shocks. The price level and thus the inflation rate are found endogenously and solutions for the prices of CPI derivatives are obtained, which are in closed form in a specialized version of the economy.

General equilibrium real and nominal interest rates

Journal of Banking & Finance 2004 28(7), 1569-1595
We derive the general equilibrium short-term real and nominal interest rates in a monetary economy affected by technological and monetary shocks and where the price level dynamics is endogenous. Assuming fairly general processes for technology and money supply, we show that an inherent feature of our equilibrium is that any real variable dynamics, in particular that of the short-term real interest rate, is driven by both monetary and real factors. This money non-neutrality is generic, as it does not stem from any friction such as price stickiness, or from a particular utility function. Non-neutrality obtains because the ex ante cost of real money holdings is random due to inflation uncertainty. We then analyze in depth a specialized version of this economy in which the state variables follow square root processes, and the representative investor has a log separable utility function. The short-term nominal rate dynamics we obtain encompasses most of the dynamics present in the literature, from Vasicek and CIR to recent quadratic and, more generally, non-linear interest rate models. Moreover, our results pave the way to several new nominal term structures.

International asset allocation: A new perspective

Journal of Banking & Finance 2003 27(11), 2203-2230
We consider an international economy where the purchasing power parity (PPP) is violated and financial asset returns and exchange rates follow, in real terms, general diffusion processes driven by K state variables. A country-specific representative individual trades on available assets to maximize the expected utility of her final consumption. Her optimal strategy is shown to contain, in addition to the usual speculative component, only two hedging components, however large is K. The first one is associated with domestic interest rate risk and the second one with the risk brought about by the co-movements of the interest rates and the market prices of risk. The implementation of the strategy thus is much easier than with the traditional Merton decomposition, as it involves estimating the characteristics of the yield curve and the market prices of risk only, rather than those of numerous (and a priori unknown) state variables. In view of the necessity for optimizing agents to account for the (partial) asset return predictability that derives from the investors’ hedging demands at equilibrium, our result significantly lessens the difficulty of achieving the optimal portfolio strategy. The second hedging term turns out to depend on interest rate differentials across countries and to encompass hedging against PPP deviations. Therefore, in contrast with previous models that obtained a (direct) currency risk hedging component in a rather ad hoc manner, our decomposition leads to optimal (indirect) currency risk hedging in a natural and general way. It also provides new insights as to the pricing of foreign exchange risk at equilibrium.

Sustainable investing with ESG rating uncertainty

Journal of Financial Economics 2022 145(2), 642-664
This paper analyzes the asset pricing and portfolio implications of an important barrier to sustainable investing: uncertainty about the corporate ESG profile. In equilibrium, the market premium increases and demand for stocks declines under ESG uncertainty. In addition, the CAPM alpha and effective beta both rise with ESG uncertainty and the negative ESG-alpha relation weakens. Employing the standard deviation of ESG ratings from six major providers as a proxy for ESG uncertainty, we provide supporting evidence for the model predictions. Our findings help reconcile the mixed evidence on the cross-sectional ESG-alpha relation and suggest that ESG uncertainty affects the risk-return trade-off, social impact, and economic welfare.
