The issue of measurement invariance commonly arises in factor-analytic contexts, with methods for assessment including likelihood ratio tests, Lagrange multiplier tests, and Wald tests. These tests all require advance definition of the number of groups, group membership, and offending model...

The well-known problem of too many instruments in dynamic panel data GMM is dealt with in detail in Roodman (2009, Oxford Bull. Econ. Statist.). The present paper goes one step further by providing a solution to this problem: factorisation of the standard instrument set is shown to be a valid...

Information and Communication Technologies (ICT) have become important tools to promote a variety of public goals and policies. In the past years much attention has been given to the expected social benefits from deploying ICT in different fields (transportation, education, public participation...

In 1950, Latin American countries capabilities were promising, and the subcontinent was thought to have a big potential for convergence. In order to understand why this prediction was not fulfilled, we apply in this paper the framework set by Fagerberg and Srholec (2008(24)). Our study of the...

We propose a Bayesian factor analysis model to rank the health of localities. Mortality and morbidity variables empirically contribute to the resulting rank, and population and spatial correlation are incorporated into a measure of uncertainty. We use county-level data from Texas and Wisconsin...

This paper investigates the individual outcomes of irrational thinking, including paranormality and non-scientific thinking. These modes of thinking are identified by factor analysis from a 2008 survey. Income and happiness are used as measures of performance. Empirical results reveal that...

Seit 1990 veröffentlicht das United Nations Development Programme (UNDP) den sogenannten Human Development Index (HDI), mit dem der Entwicklungsstand eines Landes beschrieben und verglichen werden kann. Zur Beschreibung von Entwicklung stützt sich der HDI auf nur wenige Indikatoren. Dem...

New-Keynesian models are characterized by the presence of expectations as explanatory variables. To use these models for policy evaluation, the econometrician must estimate the parameters of expectation terms. Standard estimation methods have several drawbacks, including possible lack of...
