Portfolio optimization with linear and fixed transaction costs
Investment transaction costs linear transactions
2015/8/10
We consider the problem of portfolio selection, with transaction costs and constraints on exposure to risk. Linear transaction costs, bounds on the variance of the return, and bounds on different shor...
Asymptotic Properties of Multiperiod Control Rules in the Linear Regression Model
Asymptotic Properties Multiperiod Control Rules
2015/8/5
This is the value of the control rule which would be used if one treated ,d as
known with certainty and equal to the least squares estimate. We call this rule
the least squares certainty equivalence...
Estimation and Solution of Linear Rational Expectations Models Using a Polynomial Matrix Factorization

Estimation and Solution of Linear Rational Expectations Models Using a Polynomial Matrix Factorization.
This paper develops three asymptotically equivalent tests for examining the validity of imposing
linear inequality restrictions on the parameters of linear econometric models. First we consider the ...
LOCAL AND GLOBAL TESTING OF LINEAR AND NONLINEAR INEQUALITY CONSTRAINTS IN NONLINEAR ECONOMETRIC MODELS
LOCAL AND GLOBAL TESTING NONLINEAR INEQUALITY
2015/7/31
This paper considers a general nonlinear econometric model framework that
contains a large class of estimators defined as solutions to optimization
problems. For this framework we derive several a...
Quasi-linear preferences in the macroeconomy: Indeterminacy, heterogeneity and the representative consumer

Quasi-linear preferences in the macroeconomy: Indeterminacy, heterogeneity and the representative consumer.
Electricity consumption forecasting in Italy using linear regression models
Electricity consumption Forecasting Elasticity Linear regression
2014/11/27
The influence of economic and demographic variables on the annual electricity consumption in Italy has been investigated with the intention to develop a long-term consumption forecasting model. The ti...
Quadratic BSDEs with Jumps and Related Non-linear Expectations: a Fixed-point Approach
BSDEs quadratic growth jumps non-linear Doob-Meyer decomposition dy-namical risk measures inf-convolution.
2012/9/17
We prove the existence of bounded solutions of quadratic backward SDEs with jumps, using a direct fixed point approach as in Tevzadze [35]. Under an additional standard assumption, we prove a uniquene...
Non-linear Capital Taxation Without Commitment
Capital taxation Political economy Progressivity Mirrlees
2014/9/10
We study efficient non-linear taxation of labour and capital in a dynamic Mirrleesian model incorporating political economy constraints. Policies are chosen sequentially over time, without commitment....
Perturbative Expansion Technique for Non-linear FBSDEs with Interacting Particle Method
BSDE FBSDE Asymptotic Expansion Malliavin Derivative interacting particle method branching diffusion
2012/4/28
In this paper, we propose an efficient Monte Carlo implementation of non-linear FBSDEs as a system of interacting particles inspired by the ideas of branching diffusion method. It will be particularly...
Microscopic reasoning for the non-linear stochastic models of long-range memory
microfoundations agent based models stochastic models fnancial markets long-range memory
2011/7/4
We extend Kirman's model by introducing variable event time scale. The proposed
exi-
ble time scale is equivalent to the variable trading activity observed in nancial markets.
Stochastic version ...
Analytical Approximation for Non-linear FBSDEs with Perturbation Scheme
BSDE FBSDE Four Step Scheme Asymptotic Expansion Malliavin Derivative Non-linear PDE CVA
2011/7/4
In this work, we have presented a simple analytical approximation scheme for the
generic non-linear FBSDEs. By treating the interested system as the linear decoupled
FBSDE perturbed with non-linear ...
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...
A Linear Relationship between Market Prices of Risks and Risk Aversion in Complete Stochastic Volatility Models
von-Neumann Morgenstern utility asset risk linear combination
2011/4/2
Considering a production economy with an arbitrary von-Neumann Morgenstern utility, this paper derives a general equilibrium relationship between the market prices of risks and market risk aversion un...
A method for pricing American options using semi-infinite linear programming
optimal stopping excessive functions upper bounds semiinfinite linear programming
2011/3/30
We introduce a new approach for the numerical pricing of American options. The main idea is to choose a finite number of suitable excessive functions (randomly) and to find the smallest majorant of th...
