We establish universal bounds for asset prices in heterogeneouscomplete market economies with scale invariant preferences. Namely, for eachagent in the economy we consider an artificial homogeneous economy, popu-lated solely by this agent and calculate the ”homogeneous” price of an asset...

We solve the problem of optimal securitization for an issuer facing heterogeneous investorswith arbitrary time and risk preferences. We show that the optimal securitizationis characterized by multiple nonlinear tranches, and each investor gets a portfolio of thesetranches. In particular, when...

We study survival, price impact and portfolio impact in heterogeneouseconomies. We show that, under the equilibrium risk-neutral measure,long-run price impact is in fact equivalent to survival, whereas longrunportfolio impact is equivalent to survival under an agent-specic,wealth-forward...

In the first three decades of CRSP data, value stocks have higher betas than growth stocks.Later on, the ranking is reversed and the gap in beta widens. What makes growth strategiesnowadays bear more market risk than value strategies? What are the causes of the reversalin the ranking of betas?...

The end of the lockup period of initial public offerings generally constitutes the first time corporateinsiders sell significant numbers of shares on the market. I test the hypothesis that shareholderspressure analysts to support the share price until the end of the lockup period.[...]

This paper develops a method to compute the equilibrium correspondence for exchangeeconomies with semi-algebraic preferences. Given a class of semi-algebraic exchange economiesparameterized by individual endowments and possibly other exogenous variables such as prefer-ence parameters or asset...

Multiplicity of equilibria is a prevalent problem in many economic models. Oftenequilibria are characterized as solutions to a system of polynomial equations. This pa-per gives an introduction to the application of GrÄobner basis methods for ¯nding allsolutions of a polynomial system. The...

This article examines the recent regulatory developments with regard to shortselling. Short selling regulation is an important factor in firm governancebecause it affects the way in which firms are subject to market discipline. Asthe financial crisis has attracted regulators’ notice to short...

In this paper we propose a smooth transition tree model for both the conditionalmean and variance of the short-term interest rate process. The estimation of suchmodels is addressed and the asymptotic properties of the quasi-maximum likelihoodestimator are derived. Model specification is also...

We study the exponential utility indierence value h for a contingentclaim H in an incomplete market driven by two Brownian motions.The claim H depends on a nontradable asset variably correlated withthe traded asset available for hedging. We provide an explicit se-quence that converges to h,...
