This note describes and illustrates a new Stata program, gmmcovearn, that estimates the covariance structure of earnings for a variety of models using the GMM estimator. The program estimates models that incorporate time factor loadings and cohort factor loadings on both the transitory and...

Computability theory came into being as a result of Hilbert?s attempts to meet Brouwer?s challenges, from an intuitionistc and constructive standpoint, to formalism as a foundation for mathematical practice. Viewed this way, con- structive mathematics should be one vision of computability...

This paper offers evidence relevant to the debate regarding the use of stated willingnessto- pay as a guide to public preferences about environmental management, and the possibility that individuals have distinct preferences according to whether a consumer or a citizen viewpoint is adopted....

Addressing the extra economic costs of disability seems a logical step towards alleviating elements of social exclusion for people with disabilities. This paper estimates the economic cost of disability in Ireland in terms of the additional spending needs that arise due to disability. It defines...

We investigate the structure of fuzzy aggregation rules which, for every permissible profile of fuzzy individual preferences, specify a fuzzy social preference. We show that all fuzzy aggregation rules which are strategyproof and satisfy a minimal range condition are dictatorial. In other words,...

We use univariate GARCH models of inflation and output growth and monthly data on inflation and output growth in the G7 for the 1960-2000 period to examine all possible causal relationships between inflation, output growth, real, and nominal uncertainty, and hence test for a number of economic...

Willingness-to-pay studies are increasingly being used in the evaluation of health care programmes. There are, however, methodological issues that need to be resolved before the potential of willingness-to-pay can be fully exploited as a tool for the economic evaluation of health care...

The present paper analyses different formulations of individual rights within a traditional social choice-theoretic framework and a game form framework. It proposes a theory of social situations as a basis for some new formulations of individual rights that better incorporates some positive...

In this paper we attempt to examine the issue of sustainability of current account imbalances in eight East Asia countries using the latest developments in nonstationary panel data analysis. The methods of nonstationary time series panels provide a much more promising explanation than would an...

Real analysis, founded on the Zermelo-Fraenkel axioms, buttressed by the axiom of choice, is the dominant variety of mathematics utilized in the formalization of economic theory. The accident of history that led to this dominance is not inevitable, especially in an age when the digital computer...
