Stochastic Surface Models for Commodity Futures: A 2D Kalman Filter Approach
(2011-09)
We propose a two-dimensional Kalman filter approach that, additional to the information contained in futures prices evolution over time, makes use of information contained in the term structure of commodity futures along ...
A Semiparametric Estimation of Liquidity Effects on Option Pricing
(1999-09)
This paper proposes a semiparametric option pricing model with liquidity, as proxied by the relative bid-ask spread. The nonparametric volatility function with liquidity as an explanatory variable is estimated using the ...
A Note on Wavelet Correlation and Cointegration
(2013-11)
In a recent paper Leong-Huang:2010 {Journal of Applied Statistics 37, 215–233} proposed a wavelet-correlation-based approach to test for cointegration between two time series.
However, correlation and cointegration are ...
Analysis of the relationship between International Immigration and Unemployement
(2000-10)
[EN] The relationship between the unemployment and the international immigration is getting interest while the differences between poor and rich countries are stressed. The poor countries offer cheap work force to occupy ...
Seasonal Stability Tests in gretl. An Application to International Tourism Data
(2013-09)
The seasonal stability tests of Canova & Hansen (1995) (CH) provide a method complementary to that of Hylleberg et al. (1990) for testing for seasonal unit roots. But the distribution of the CH tests are unknown in small ...
Time-dependent outside option in an alternating offers bargaining model
(1997)
In this work I consider an alternating offers bargaining model in which a time-dependent outside option is introduced. The purpose of this work is to analyze relationships between S.P.E. utility pairs induced by such a ...
A time varying coefficient model for panel data: Foreign Direct Investment in European OECD countries
(2007-04)
The present article reexamines some of the issues regarding the Knowledge-Capital Model that encompasses both horizontal and vertical Foreign Direct Investment described in detail in the literature. The empirical support ...
Optimal Environmental Taxation When Goods and Contamination are Durable
(1999-11)
[EN] This paper analyzes the effects of optimal taxation on a polluting monopolist who produces a durable good and cannot precommit to future sale prices. The government establishes the taxes that maximize social welfare, ...
Scenario Cluster Lagrangian Decomposition in two stage stochastic mixed 0-1 optimization
(2012)
In this paper we introduce four scenario Cluster based Lagrangian Decomposition (CLD) procedures for obtaining strong lower bounds to the
(optimal) solution value of two-stage stochastic mixed 0-1 problems. At each iteration ...
Lagrangean decomposition for large-scale two-stage stochastic mixed 0-1 problems
(2010-07)
In this paper we study solution methods for solving the dual problem corresponding to the Lagrangean Decomposition of two stage stochastic mixed 0-1 models. We represent the two stage stochastic mixed 0-1 problem by a ...
