We investigate a general class of dynamical open-bid combinatorial auction protocols termed price-demand procedures, where the auctioneer asks buyer-dependent price vectors and buyers reveal demand sets. Such revelations are easier to practice than the revelations of entire valuations at once....

For estimating the integrated volatility by using high frequency data, Kunitomo and Sato (2008, 2011, 2013) have proposed the Separating Information Maximum Likelihood (SIML) method when there are micro-market noises. The SIML estimator has reasonable nite sample properties and asymptotic...

This study evaluates the economic impact of product innovation by using firm-level data obtained from the Community Innovation Survey conducted in Japan. It accounts for possible technological spillovers from innovation activities, and examines the extent to which new-to-market product...

We investigate revenue maximization in general allocation problems with incomplete information, where we assume quasi-linearity, private values, independent type distributions, and single-dimensionality of type spaces. We require a mechanism to satisfy strategy-proofness and ex-post individual...

In this paper, we propose an efficient Monte Carlo implementation of a non-linear FBSDE as a system of interacting particles inspired by the idea of the branching diffusion method of McKean. It will be particularly useful to investigate large and complex systems, and hence it is a good...

The Box-Cox transformation is applied to linear mixed models for analyzing positive and clustered data. The problem is that the maximum likelihood estimator of the transformation parameter is not consistent. To fix it, we suggest a simple and consistent estimator for the transformation parameter...

The problem of estimating large covariance matrices with use of factor models is addressed when both the sample size and the dimension of covariance matrix tend to innity. In this paper, we consider a general class of weighted estimators which includes (i) linear combinations of the sample...

After the First Sino-Japanese War and the Russo-Japanese War, Japan annexed Korea in 1910. We exploit this event as a natural experiment to investigate the effect of improved market access on the population growth. It is found that the tariff reduction raised the growth rate of population, and...

We propose an information criterion which measures the prediction risk of the predictive density based on the Bayesian marginal likelihood from a frequentist point of view. We derive the criteria for selecting variables in linear regression models by putting the prior on the regression...

This paper provides the optimal position management strategy for a market maker who has to face uncertain customer orders in an “illiquid†market, where the market maker’s continuous trading through a traditional exchange incurs stochastic linear price impacts. In addition, it...
