This paper presents a simple but effective method to exploit the Graphical Processing Unit of a PC to solve a dynamic incomplete market equilibria with heterogeneous agents. The method is an adjusted brute force search and does not use first order conditions and neither imposes differentiability...

The international CAPM (ICAPM) extends the classical CAPM by adding exchange rate risks as priced factors. In the literature, both conditional and unconditional tests confirm the significance of exchange rate risk. However, typical conditional tests of the ICAPM include few instruments with...

We jointly model the information choice and portfolio allocation problem of institutional investors who are concerned about their performance relative to a benchmark. Benchmarking increases an investor's effective risk-aversion, which reduces his willingness to speculate and, consequently, his...

We study the joint portfolio and information choice problem of institutional investors who are concerned about their performance relative to a benchmark. Benchmarking influences information choices through two distinct economic mechanisms. First, benchmarking reduces the number of shares in...

In this work we propose a new and general approach to build dependence in multivariate Lévy processes. We fully characterize a multivariate Lévy process whose margins are able to approximate any Lévy type. Dependence is generated by one or more common sources of jump intensity separately in...

In this work we propose a new multivariate pure jump model. We fully characterize a multivariate Lévy process with finite- and infinite-activity components in positive and negative jumps. This process generalizes the variance gamma process, featuring a ‘stochastic volatility’ effect due to...

In this work we propose a new approach to build multivariate pure jump processes. We introduce linear and nonlinear dependence, without restrictions on marginal properties, by imposing a multi-factorial structure separately on both positive and negative jumps. Such a new approach provides higher...
