Testing for Welfare Comparisons when Populations Differ in Size

Duclos, Jean-Yves; Zabsonré, Agnès - Centre Interuniversitaire sur le Risque, les Politiques … - 2010

Assessments of social welfare do not usually take into account population sizes. This can lead to serious social evaluation flaws, particularly in contexts in which policies can affect demographic growth. We develop in this paper a little-known though ethically attractive approach to correcting...

The Peer Performance of Hedge Funds

Ardia, David; Boudt, Kris - Centre Interuniversitaire sur le Risque, les Politiques … - 2013

An essential component in the analysis of (hedge) fund returns is to measure its performance with respect to the group of peer funds. Through the analysis of risk-adjusted return percentiles an answer is given to the question how many funds are out-performed by the focal fund. In case all funds...

A New Bootstrap Test for the Validity of a Set of Marginal Models for Multiple Dependent Time Series: an Application to Risk Analysis

Ardia, David; Gatarek, Lukasz; hoogerheide, Lennart F. - Centre Interuniversitaire sur le Risque, les Politiques … - 2014

A novel simulation-based methodology is proposed to test the validity of a set of marginal time series models, where the dependence structure between the time series is taken ‘directly’ from the observed data. The procedure is useful when one wants to summarize the test results for several...

A Review of Recent Theoretical and Empirical Analyses of Asymmetric Information in Road Safety and Automobile Insurance

Dionnne, Georges; Michaud, Pierre-Carl; Pinquet, Jean - Centre Interuniversitaire sur le Risque, les Politiques … - 2012

Road safety policies and automobile insurance contracts often use incentive mechanisms based on traffic violations and accidents to promote safe driving. Can these mechanisms improve road safety efficiently? Do they reduce asymmetric information between drivers and insurers and regulators? In...

The Empirical Measure of Information Problems with Emphasis on Insurance Fraud and Dynamic Data

Dionne, Georges - Centre Interuniversitaire sur le Risque, les Politiques … - 2012

We discuss the difficult question of measuring the effects of asymmetric information problems on resource allocation. Three problems are examined: moral hazard, adverse selection, and asymmetric learning. One theoretical conclusion, drawn by many authors, is that information problems may...

Logique et tests d'hypotheses: reflexions sur les problemes mal poses en econometrie

DUFOUR, Jean-Marie - Département de Sciences Économiques, Université de … - 2001

Dans ce texte, nous analysons les développements récents de l’économétrie à la lumière de la théorie des tests statistiques. Nous revoyons d’abord quelques principes fondamentaux de philosophie des sciences et de théorie statistique, en mettant l’accent sur la parcimonie et la...

ARMA Sieve bootstrap unit root tests

Richard, Patrick - Département d'économique, Faculté d'administration - 2007

the AR sieve bootstrap, proposed by Park (2002) and Chang and Park (2003), may alleviate this problem. We propose sieve … bootstrap DGPs are established and a proof of the asymptotic validity of the resulting ADF bootstrap tests is provided. Through … more robust to the underlying DGP than that of the AR sieve bootstrap. In particular, the new sieve bootstraps perform much …

Finite-Sample Inference Methods for Simultaneous Equations and Models with Unobserved and Generated Regressors

DUFOUR, Jean-Marie; JASIAK, Joanna - Département de Sciences Économiques, Université de … - 1998

We propose finite sample tests and confidence sets for models with unobserved and generated regressors as well as various models estimated by instrumental variables methods. The validity of the procedures is unaffected by the presence of identification problems or "weak instruments", so no...
