We revisit the classical dynamic inventory management problem of Scarf (1959) from the perspective of a decision-maker who has n historical selling seasons of data and must make ordering decisions for the upcoming season. We develop a nonparametric estimation procedure for the (S, s) policy that...

While the existing literature has identified a sizable incumbency advantage in single-member district (SMD) races in developed democracies, we argue that some political and institutional contexts of Japan’s Lower House elections would undermine the incumbency advantage. Our regression...

Trapezoidal fuzzy numbers have numerous advantages over triangular fuzzy numbers as they have more generalized form. In this paper, two sample statistical test of hypothesis for means in normal population with interval data is given. The decision rules whether to accept or reject the null...

In this paper we investigate a dynamic linear panel regression model with measurement error. We consider the panel data estimation whose time dimension (T) is not small and comparable to the cross sectional dimension (N). First, we show that the 2SLS estimator suffers from the bias problem due...
