Wilkinson Tests are entry-level tests for assessing the numerical accuracy of statistical computations that have been applied to statistical software packages. Some software developers whose products have failed these tests have corrected deficiencies in subsequent versions. Thus, these tests...

A number of test statistics arising in econometrics can be expressed as a weighted ratio of quadratic forms in normal variables (ROQNV), but tractable expressions for computing their pdf and cdf do not exist. A numerical method for evaluating the cdf is given in Imhof (1961) but has the...

We formulate an optimizing-agent model in which both labor and product markets exhibit monopolistic competition and staggered nominal contracts. We demonstrate that the household's unconditional expected utility can be expressed in terms of the unconditional variances of the outgap gap,...

This paper discusses the asymptotic and finite-sample properties of the Efficient Method of Moments (EMM) when applied to estimating stationary ARMA models. Issues such of identification, model selection, and testing are also discussed. The properties of these estimators are compared to those of...

This paper shows that the recent literature that tests for a long-run Fisher relationship using cointegration analysis is seriously flawed. Cointegration analysis assumes that the variables in question are I(1) or I(d) with the same d. Using monthly post-war U.S. data from 1959-1997, we show...

In this paper, we use the Wang and Zender (98) model of auctions, and derive, using optimal control, the optimal bidding strategy in the Spanish Treasury Bill auctions (STBA). Spain is the only country that uses a hybrid system of discriminatory and uniform price auctions: winning bidders pay...

This paper investigates the accuracy of the log-linear approximation method in welfare calculations, especially in measuring welfare gains of international risk sharing. We derive closed-form solutions for a two-country complete market economy using log-linearization and a nonlinear solution...

This paper examines the pattern of consumption and savings when heterogeneous agents enter into marriage and have the option of dissolving the marriage if there exists no set of consumption allocations that can preserve the union. The research presents an analysis of this scenario using dynamic...

The existing literature on income inequality and economic growth can be decomposed broadly into two main strains. One, recently advanced, investigates the impact of the initial inequality on subsequent economic growth. The other, rather older, strain examines the evolution of inequality along...

Many numerical methods to price options have been suggested in the finance literature. This paper aims at reviewing several numerical approaches in order to discuss their practical strenghts and/or weaknesses. The problem under investigation is a multivariate contingent claims model with three...
