By using the empirical likelihood (EL), we consider the construction of pointwise confidence intervals (CIs) for nonparametric nonlinear nonstationary regression models with nonlinear nonstationary heterogeneous errors. It is well known that the EL-based CI has attractive properties such as data...

This paper derives the asymptotic distribution of Tanaka's score statistic under moderate deviation from a unit root in a moving average model of order one or MA(1). We classify the limiting distribution into three types depending on the order of deviation. In the fastest case, the convergence...

This paper examines the social value of information in symmetric Bayesian games with quadratic payoff functions and normally distributed public and private signals. The main results identify necessary and sufficient conditions for welfare to increase with public or private information. Using the...

We consider a non-cooperative sequential bargaining game with incomplete information where two players negotiate for mechanisms with ex post verifiable types at the interim stage. We prove the existence of a stationary sequential equilibrium of the bargaining game where the ex post Nash...

本稿では、動学的確率的一般均衡モデルのマクロ計量経済分析における役割を、Geweke (2010)による強解釈と弱解釈および最小解釈の3分類に従って批判的に略説する。最小解釈の応用例として、Kano and Nason...

We study a new monotonicity problem in combinatorial auctions called goods revenue　monotonicity, which requires that the auctioneer earn no more revenue by dropping goods from the endowments. Although no mechanism satisfies goods revenue monotonicity together with strategy-proofness,...

In this paper, we consider a natural procedure of decision-making, called a “Grouping Choice Method”, which leads to a kind of bounded rational choices. In this procedure a decision-maker (DM) first divides the set of available alternatives　into some groups and in each group she chooses...

A decision maker is presented with two preference orders over n objects and chooses the one which is “closer” to his own preference order. We consider several plausible comparison rules that the decision maker might employ. We show that when n is large and the pair of orders to be compared...
