In this article, a type of bivariate rational interpolation function is constructed for preserving image texture structure, which integrates polynomial functions with a rational function. On the basis of this model, an image interpolation algorithm for texture preserving is proposed. First, an...

This paper provides some additional empirical evidence on the effect of exchange‐rate volatility on exports. The novelties of the study include: a regime‐switching model in conditional volatility is employed to better capture the exchange‐rate uncertainty; a 2SLS method as suggested by...
