Reconstructing Chi-squared Intra-table Distances in the Analysis of a Set of Contingency Tables
(2007-07)
To study similarities among the set of rows -and columns- of a contingency table, Correspondence Analysis uses chi-squared distances between row profiles -and column profiles- of that table. This article presents a factor ...
An empirical comparison of the performance of alternative option pricing models
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2002)
This paper presents a comparison of alternative option pricing models based neither on jump-diffusion nor stochastic volatility data generating processes. We assume either a smooth volatility function of some previously ...
Consumer Confidence and Yield Spreads in Europe
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2005-02)
This paper shows the extraordinary capacity of yield spreads to anticipate consumption growth as proxy by the Economic Sentiment Indicator elaborated by the European Commission in order to predict turning points in business ...
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 ...
Commitment Power in a Non-Stationary Durable-Good Market
(2001-05)
This paper derives and evaluates the decisions of a durable good monopolist in a context where demand for the services of the durable good changes over time. It shows that, if the size of the market decreases over time, ...
A two-stage stochastic integer programming approach
(2005)
We present an algorithmic approach for solving two-stage stochastic mixed 0-1 problems. The first stage constraints of the Deterministic Equivalent Model have 0--1 variables and continuous variables. The approach uses the ...
The Weekend-Dividend Effect in the Spanish Market
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2002-06)
In this paper we develop an econometric test of a corollary of the irrelevance of the dividend policy principle, namely, that the rescheduling of dividends does not affect the market valuation of the firm. In particular, ...
Absorbing Sets in Coalitional Systems
(2001-12)
The purpose of this paper is twofold: First, to present an approach and a solution for analyzing the stability of coalition structures: We define a coalitional system (a set and a binary relation on that set) that explains ...
Nonparametric estimation of time varying parameters under shape restrictions
(2001-01)
In this paper we propose a new method to estimate nonparametrically a time varying parameter model when some qualitative information from outside data (e.g. seasonality) is available. In this framework we make two main ...
Predicting Betas: Two new methods
(2009)
Betas play a central role in modern finance. The estimation of betas from historical data and their extrapolation into the future is of considerable practical interest. We propose two new methods: the first is a direct ...
