In this paper we study the equilibrium in a heterogeneous economy with twogroups of investors. Over-confident experts incorrectly assume that their signalfor the drift of the dividend process is correlated with the true drift, butinterpret the signal otherwise perfectly. Rational laymen avoid...

Variance contracts permit the trading of ’variance risk’, i.e. the risk that the realizedvariance of stock returns changes randomly over time. We discuss why investorsmight want to trade this type of risk, and why they might prefer a variance contractto standard calls and puts for this...

Model mis-specification can cause substantial utility losses in portfolio planning.In this paper, we compare two approaches to cope with this problem,robust control and learning. We derive the optimal portfolio strategies and theutility losses due to model mis-specification. Surprisingly,...

The observed prices of out-of-the money put options seem too high given standardderivative pricing models. One possible explanation is a Peso problem: crashes (forwhich the payoff of a put is high) are taken into account for pricing, but are under-represented in the data sets used for empirical...

The vast majority of approaches to risk management, hedging, or portfolio planningassume that some model is given. However, under model risk, the true data gener-ating process is not known. The focus of this paper is on problems related to thehedging of derivative contracts. We explain the main...

It has been documented that vertical customer-supplier links between industries are the basis for strong cross-sectional stock return predictability (Menzly and Ozbas (2010)).We show that robust predictability also arises from horizontal links between industries, i.e., from the fact that...

We study the effects of market incompleteness on speculation, investor survival, and asset pricing moments, when investors disagree about the likelihood of jumps and have recursive preferences. We consider two models. In a model with jumps in aggregate consumption, incompleteness barely matters,...

In a parsimonious regime switching model, expected consumption growth varies over time. Adding in ation as a conditioning variable, we uncover two states in which expected consumption growth is low, one with high and one with negative expected in ation. Embedded in a general equilibrium asset...

Directed links in cash flow networks affect the cross-section of price exposures and market prices of risk in equilibrium. In an asset pricing model featuring mutually exciting jumps, we measure directedness through an asset's shock propagation capacity (spc). In the model, we prove: (i) Cash...

We introduce Implied Volatility Duration (IVD) as a new measure for the timing of uncertainty resolution, with a high IVD corresponding to late resolution. Portfolio sorts on a large cross-section of stocks indicate that investors demand on average more than five percent return per year as a...
