In this paper, we introduce a model that incorporates features of the fully transparent hotel booking systems and enables estimates of hotel choice probabilities in a group based on the room charges. Firstly, we extract necessary information for the estimation from big data of online booking for...

In this paper, we investigate an optimal room charge problem for a hotel that considers maximization of the expected sales. We introduce a waterfall model and a multinomial logit model for hotels in the same area and the same price range which offer limited number of rooms. The models reflect...

This is an online appendix of "Sup-inf/inf-sup problem on choice of a probability measure by FBSDE approach". Particularly, we provide proofs of Propositions 1-3 and an example of FBSDEs, in which sgn(Z1); sgn(Z2) are determined by solving the FBSDEs explicitly, for Section III-B in the original...

This paper presents a new asset pricing model incorporating fundamental uncertainties by choice of a probability measure. This approach is novel in that we incorporate uncertainties on Brownian motions describing risks into the existing asset pricing model. Particularly, we show extensions of...

This paper investigates derivatives pricing under existence of liquidity costs and market impacts for the underlying asset in continuous time. Firstly, we formulate the charge for the liquidity cost and the market impact on the derivatives prices through a stochastic control problem that aims to...

This paper presents an application of a linear quadratic stochastic differential game to a financial model that describes trading behaviors of different types of players in a high frequency stock market. Stability of the stock market in a high frequency environment is a central issue in...

This paper considers a new problem for portfolio optimization with a choice of a probability measure, particularly, an optimal investment problem under sentiments. Firstly, we formulate the problem as a sup-sup-inf problem consisting of optimal investment and a choice of a probability measure...
