In practice, the supplier often offers the retailers a trade credit period M and the retailer in turn provides a trade credit period N to her/his customer to stimulate sales and reduce inventory. From the retailer’s perspective, granting trade credit not only increases sales and revenue but also increases opportunity cost (i.e., the capital opportunity loss during credit period) and defau...

This paper introduces a numerical method for solving the vasicek model by using a stochastic operational matrix based on the triangular functions (TFs) in combination with the collocation method. The method is stated by using conversion the vasicek model to a stochastic nonlinear system of $2m+2$ equations and $2m+2$ unknowns. Finally, the error analysis and some numerical examples are provided...

We synthesize the financial crisis contagion literature through the gravity model from physics and test the hypothesis that the severity of contagion relates positively to trade and financial linkages but negatively to psychic distance between countries, when macroeconomic fundamentals and institutional factors are controlled. The psychic distance variable, a behavioral predictor constructed al...

Does Japanese trade in manufactured goods differ from the rest-of-the world average and from the U.S.? We use a simple industry-level gravity model and 1981-1998 data to answer this question. We construct a measure of normalized imports by dividing bilateral industry-level imports by the importer's aggregate absorption and the exporter's industry output. We find that Japan imports less than oth...
