The Impact of Effect Size Heterogeneity on Meta-Analysis: A Monte Carlo Experiment

Koetse, Mark J.; Florax, Raymond J.G.M.; de Groot, … - 2007

In this paper we use Monte Carlo simulation to investigate the impact of effect size heterogeneity on the results of a meta-analysis. Specifically, we address the small sample behaviour of the OLS, the fixed effects regression and the mixed effects meta-estimators under three alternative...

Instrumental Variable Estimation for Duration Data

Bijwaard, Govert E. - 2008

In this article we develop an Instrumental Variable estimation procedure that corrects for possible endogeneity of a variable in a duration model. We assume a Generalized Accelerated Failure Time (GAFT) model. This model is based on transforming the durations and assuming a distribution for...

Partial Likelihood-Based Scoring Rules for Evaluating Density Forecasts in Tails

Diks, Cees; Panchenko, Valentyn; van Dijk, Dick - 2008

We propose new scoring rules based on partial likelihood for assessing the relative out-of-sample predictive accuracy of competing density forecasts over a specific region of interest, such as the left tail in financial risk management. By construction, existing scoring rules based on weighted...

Estimation methods in panel data models with observed and unobserved components: A Monte Carlo study

Castagnetti, Carolina; Rossi, Eduardo - 2008

Recently some new techniques have been proposed for the estimation of the slope coefficients in presence of unobserved components. Though, the presence of common observed and unobserved factors is neither considered or the estimation of their impacts is not taken into account. In this work a...

Weak Instruments and Weak Identification in Estimating the Effects of Education on Democracy

Bobba, Matteo; Coviello, Decio - 2006

Is there any relation between education and democracy? Once we correct for weak instruments and identify education as `weakly exogenous` we find new evidence that education systematically predicts democracy. Our results are robust across model specification, instrumentation strategies, and samples.

Issues concerning the approximation underlying the spectral representation theorem

Lippi, Marco - 2003

In many important textbooks the formal statement of the Spectral RepresentationTheorem is followed by a process version, usually informal, stating thatany stationary stochastic process g is the limit in quadratic mean of asequence of processes, each consisting of a finite sum of...

Estimativas da função de exportações brasileiras agregadas com dados das contas nacionais trimestrais (1995-2009)

Schettini, Bernardo Patta; Squeff, Gabriel Coelho; … - 2011

This paper presents new econometric specifications for the Brazilian exports in the period 1995-2009 using data from the Quarterly Accounts and allowing for nonlinearities. In the cointegrating vector, there is evidence of a level shift, but the elasticities have not changed significantly. The...

Economic Returns to Education: What We Know, What We Don't Know, and Where We Are Going Some Brief Pointers

Harmon, Colm P. - 2011

The estimation of the economic return to education has perhaps been one of the predominant areas of analysis in applied economics for over 50 years. In this short note we consider some of the recent directions taken by the literature, and also some of the blockages faced by both science and...
