We show that by modeling the time series of mortality rate changes rather than mortality rate levels we can better model human mortality. Leveraging on this, we propose a model that expresses log mortality rate changes as an age group dependent linear transformation of a mortality index. The...

We consider the problem of finding a strategy that tracks the volume weighted average price (VWAP) of a stock, a key measure of execution quality for large orders used by institutional investors. We obtain the optimal, dynamic, VWAP tracking strategy in closed form in a model with general price...

Performance fees that are designed to incentivize money managers to exert more effort may also distort a manager's risk choices. In this paper, we analyze the impact of the standard performance fee contract that includes what is known as a high-water mark provision. We investigate the effect the...

To capture mean reversion and sharp seasonal spikes observed in electricity prices, this paper develops a new stochastic model for electricity spot prices by time changing the Jump Cox-Ingersoll-Ross (JCIR) process with a random clock that is a composite of a Gamma subordinator and a...

The Basic Affine Jump Diffusion (BAJD) process is widely used in financial modeling. In this paper, we develop an exact analytical representation for its transition density in terms of a series expansion that is uniformly-absolutely convergent on compacts. Computationally, our formula...

En el marco de los Debates Presidenciales de 2014, Fedesarrollo lideró la elaboración de varios documentos con propuestas de política pública en áreas críticas para el desarrollo económico y social del país. En este documento Hernando José Gómez y Daniel Mitchell abordan uno de esos...
