We study a marginal empirical likelihood approach in scenarios when the number of variables grows exponentially with the sample size. The marginal empirical likelihood ratios as functions of the parameters of interest are systematically examined, and we find that the marginal empirical likelihood ratio evaluated at zero can be used to differentiate whether an explanatory variable is contributin...

In this paper we construct sets of marginal vectors of a TU game with the property that if the marginal vectors from these sets are core elements, then the game is convex. This approach leads to new upperbounds on the number of marginal vectors needed to characterize convexity. Another result is that the relative number of marginals needed to characterize convexity con-

This paper compares various nonparametric models for the estimation of farm specific marginal costs function in the dairy sector. Specifically, locally weighted regression approaches using theory-consistent cost function frameworks as polynomials in the nonparametric approach are applied. A comparison of average marginal cost levels as well as marginal cost distributions across farms illustrate...

This study examines the marginal intra-industry trade (MIIT) and its components horizontally, and marginal vertical intra-industry trade (MVIIT) applied to the United States. We present an alternative methodology to evaluate marginal intra-industry trade (MIIT) which was presented by Thom and McDowell (1999) and Azhar and Elliot (2008). Using a panel data approach, the results show a negative c...
