A One-Factor Conditionally Linear Commodity Pricing Model under Partial Information

A one-factor asset pricing model with an Ornstein–Uhlenbeck process as its state variable is studied under partial information: the mean-reverting level and the mean-reverting speed parameters are modeled as hidden/unobservable stochastic variables. No-arbitrage pricing formulas for derivative securities written on a liquid asset and exponential utility indifference pricing formulas for derivative securities written on an illiquid asset are presented. Moreover, a conditionally linear filtering result is introduced to compute the pricing/hedging formulas and the Bayesian estimators of the hidden variables.     

The effects of fishery harbor-based brands on the brand equity of shore fish: An empirical study of branded mackerel in Japan

In Japan, some fishery cooperative associations use their fishery harbor names as a brand to differentiate their own shore fish. Most notable is the branding of mackerel. In this paper, we analyze the effects of branding using a discrete/continuous model. The results are as follows. First, there is first-mover advantage in the branding of mackerel. For instance, unlike other brands of mackerel, Seki-saba as the pioneering brand can increase its brand equity. Second, other brands have opposing effects that increase and decrease the brand equity of the pioneering brand. We find the former is strongest in the early stages of fishery branding when there are few competing brands of mackerel, while the latter becomes stronger in later stages when many other brands emerge.     

Lattice structure of knowledge and agreeing to disagree

This paper is a contribution to the study of the underlying mathematical structure of common-knowledge, which gives the well-known result of Aumann about the impossibility of ‘agreeing to disagree’. We present the Bayesian subjective probability model with player's belief: i.e. a triple (? %plane1D;4AF;, μ), in which i is a player. ? is a lattice in the field of sets of a state space Ω, %plane1D;4AF;, is a correspondence assigning to each state ω a filter %plane1D;4AF;(ω) in ?, and μ is a common-prior. For this model, we impose none of the important restrictions on the information structure in the Aumann-Bacharach model: axiom of knowledge K₁. axiom of transparency K₂ and axiom of wisdom K₃. We can extend both the disagreement theorem of Aumann and the agreement theorem of Geanacoplos and Polemarchakis under the assumption that each ? is an Artinian lattice.     

Böhm-Bawerk and Shibata on power or market

In 1935 the Japanese economist Shibata criticized Böhm-Bawerk's discussion to deny the role of power on market and argued that the validity of Böhm-Bawerk's conclusion depends crucially on his special assumptions on the structure of production in his theory of interest. Unfortunately, both Böhm-Bawerk and Shibata used in their discussions an untenable supposition that the value of heterogeneous capital, which depends on values of endogenous variables, can be given exogenously. Our aim is to reconsider the problem in the light of a new interpretation of Böhm-Bawerk's theory of interest, which is free from this supposition.     

Paradoxical trade patterns and terms of trade

It is shown that, when a monopoly is present in a two-country, two-commodity world, the terms-of-trade do not necessarily fall in between the pre-trade relative prices of the two countries, and that these pre-trade prices do not unequivocally determine the pattern of trade.     

Industry‐specific Real Effective Exchange Rates and Export Price Competitiveness: The Cases of Japan,China, and Korea

This paper constructs a new dataset of the industry‐specific real effective exchange rate, based on the producer price indices, for Japan, China, and Korea on a monthly basis from January 2001 to February 2013 in order to provide a better indicator for export price competitiveness. By conducting simulation analysis, we found that Korean electrical machinery firms substantially improved their cost competitiveness by lowering their production costs during the Korean won appreciation period, while Japanese firms' large plant investment caused by management misjudgments led to excessive production capacity, which resulted in the deterioration of Japanese export competitiveness. A structural vector autoregression analysis also reveals that industry differences of cost competitiveness as well as nominal exchange rate changes have significant impact on export performances of Japan and Korea.
