Technology Choice and Capacity Portfolios under Emissions Regulation
Pollution and Pollutants Governing Rules Regulations and Reforms Technology Production
2015/4/27
We study the impact of emissions tax and emissions cap-and-trade regulation on a firm's technology choice and capacity decisions. We show that emissions price uncertainty under cap-and-trade results i...
Optimal portfolios in commodity futures markets
futures contract commodity markets portfolio optimization stochastic partial differential equations
2012/4/28
We consider portfolio optimization in futures markets. We model the entire futures price curve at once as a solution of a stochastic partial differential equation. The agents objective is to maximize ...
Building portfolios of stocks in the Sao Paulo Stock Exchange using Random Matrix Theory
Building portfolios stocks the Sao Paulo Stock Exchange Random Matrix Theory
2012/3/2
Using Random Matrix Theory, we build a covariance matrix between stocks of the BM&F-Bovespa (Bolsa de Valores, Mercadorias e Futuros de S\~ao Paulo) which is cleaned of some of the noise due to the co...
Notional portfolios and normalized linear returns
Notional portfolios normalized linear Portfolio Management
2011/7/25
Abstract: The vector of periodic, compound returns of a typical investment portfolio is almost never a convex combination of the return vectors of the securities in the portfolio. As a result the ex p...
Default Clustering in Large Portfolios: Typical and Atypical Events
Large Portfolios Default Clustering Typical Atypical Events
2011/7/22
Abstract: We develop a dynamic point process model of correlated default timing in a portfolio of firms, and analyze typical and atypical default profiles in the limit as the size of the pool grows. I...
Capital allocation for credit portfolios under normal and stressed market conditions
Capital allocation credit portfolios normal stressed market conditions
2010/10/21
If the probability of default parameters (PDs) fed as input into a credit portfolio model are estimated as through-the-cycle (TTC) PDs stressed market conditions have little impact on the results of ...
On the significance of REITs in international portfolios –A U.S. perspective
portfolio investments allocation strategy optimization
2010/10/18
Taking a U.S. investor’s perspective, this paper applies a bi-level asset allocation strategy
and an all-inclusive optimization technique for assessing the benefits from including real estate investm...
Minimal $f$-divergence martingale measures and optimal portfolios for exponential Levy models with a change-point
f-divergence exponential Levy models
2010/10/19
We consider the exponential Levy models and we study the conditions under which f-minimal equivalent martingale measure preserves Levy property. Then we give a general formula for optimal strategy in...
Monte Carlo Portfolio Optimization for General Investor Risk-Return Objectives and Arbitrary Return Distributions: a Solution for Long-only Portfolios
Portfolio Optimization Optimisation Random Portfolio Monte Carlo Simplex
2010/10/21
We develop the idea of using Monte Carlo sampling of random portfolios to solve portfolio investment problems. In this first paper we explore the need for more general optimization tools, and conside...

Quantum Portfolios Observables Neutral Valuation Model
2010/10/19
Quantum Portfolios of quantum algorithms encoded on qbits have recently been reported. In this paper a discussion of the continuous variables version of quantum portfolios is presented. A risk neutral...
Analytical, free of time consuming Monte Carlo simulations, framework for credit portfolio systematic risk metrics calculations is presented. Techniques are described that allow calculation of portfo...
Accounting for risk of non linear portfolios: a novel Fourier approach
Accounting non linear portfolios a novel Fourier approach
2010/10/18
The presence of non linear instruments is responsible for the emergence of non Gaussian features in the price changes distribution of realistic portfolios, even for Normally distributed risk factors....

Minimum Variance Portfolios Coordinate-Wise Descent Algorithms
2010/10/20
In this short report, we discuss how coordinate-wise descent algorithms can be used to solve minimum variance portfolio (MVP) problems in which the portfolio weights are constrained by $l_{q}$ norms,...
