In a market with one safe and one risky asset, an investor with a long horizon, constantinvestment opportunities, and constant relative risk aversion trades with small proportionaltransaction costs. We derive explicit formulas for the optimal investment policy, its impliedwelfare, liquidity...

This appendix extends the empirical results in Chesney, Crameri, and Mancini (2011). Informedtrading activities on put and call options are analyzed for 19 companies in the bankingand insurance sectors from January 1996 to September 2009. Our empirical findings suggestthat certain events such as...

We develop an econometric methodology to infer the path of risk premia from large unbalancedpanel of individual stock returns. We estimate the time-varying risk premia implied by conditional linearasset pricing models where the conditioning includes instruments common to all assets and asset...

We derive nonparametric tests of symmetry using asymmetric kernels with either shrinkingor fixed bandwidths. We show how to extend the approach to examine conditional symmetry byderiving conditions under which our tests are applicable to residuals from semiparametric modelswith a (sufficiently...

Some investment advisors offer multiple versions of a fund with the same manager and highlycorrelated returns. But these “twin” funds are separate portfolios for different investors withdiffering abilities to select and monitor managers. Using a matched sample of retail andinstitutional twin...

The paper is the first one outside the high-frequency domain to use sentiment-signednews to directly compare news and no-news stock returns. This is done by estimatingwhether returns on positive, neutral and negative news days are significantly differentfrom the average daily return for a large...

We explore the pricing of variance risk by decomposing stocks' total variance into systematicand idiosyncratic return variances. While systematic variance risk exhibits a negative priceof risk, common shocks to the variances of idiosyncratic returns carry a large positive riskpremium. This...

This paper presents an equilibrium model in a pure exchange economywhen investors have three possible sources of heterogeneity. Investorsmay differ in their beliefs, in their level of risk aversion andin their time preference rate. We study the impact of investors heterogeneityon equilibrium...

Climate change is one of the greatest challenges facing our planet in the foreseeable future anddespite the urgency of the situation global GHG emissions are still increasing. In this context,and since future climate changes appear now unavoidable to some extent, adaptation measureshave recently...

We investigate whether a bank’s performance during the 1998 crisis, which was viewed at the timeas the most dramatic crisis since the Great Depression, predicts its performance during the recentfinancial crisis. One hypothesis is that a bank that has an especially poor experience in a...
