A single formula assigns a continuous utility function to every representable preference relation.

This paper presents a generalized pre-averaging approach for estimating the integrated volatility. This approach also provides consistent estimators of other powers of volatility in particular, it gives feasible ways to consistently estimate the asymptotic variance of the estimator of the...

Sufficient conditions are provided for a possibly incomplete preference pre-order on a topological space to be closed in the product space if and only if it has closed upper and lower contour sets. Notably, it is shown that the two properties are equivalent if the domain of the preorder is a...

This study identified the discriminating factors among continuous and intermittent exporting firms from the South of Minas, regarding variables from the external environment, the internal characteristics and technological innovation. A binary logit model was defined to research the determinants...
