The hypothesis that when firms obtain financing, they prefer internal sources to external sources is known as the pecking order hypothesis. We model firms' financing activities implied by the pecking order hypothesis by a sequential logit model. Then, we propose to test the pecking order...

Recently Chiba and Kobayashi (2013) have proposed the Lagrange multiplier (LM) test for the null hypothesis that volatilities of two asset return processes are driven by only one stochastic volatility (SV) process in a bivariate SV model. They apply their LM test to Asian stock market index...

In this article, we develop the asymptotic theory of Hwang and Basawa (2005) for explosive random coefficient autoregressive (ERCA) models. Applying the theory, we prove that a locally best invariant (LBI) test in McCabe and Tremayne (1995), which is for the null of a unit root (UR) process...

The multinomial probit (MP) and ordered probit (OP) models have been widely used in empirical econometric analyses in which a dependent variable falls into several categories. In this paper, we consider another class of probit models, called the correlated sequential probit(CSP) model, and show...
