Bulk shipping providers predominantly supply transportation services for bulk cargo, such as iron ore, grain and coal. As steel price index is a leading indicator of Baltic Dry Index, the cost of marine fuel becomes one of the key costs for shipping providers. By collecting data and building a...

This paper focuses on the question of whether or not a reduction of the knowledge barrier is good for welfare. Based on a dynamic monopoly setting with simultaneous investment decisions in process as well as in product Research & Development (R&D), we show that a reduction of the knowledge...

This paper analyzes whether the market portfolio is efficiently related to benchmark portfolios formed on size, value, momentum and reversal with various utility theories by using stochastic dominance criteria. The results support the prospect theory including assumption of loss aversion at...

The research perspective of gold is either as a commodity or as a financial asset in most previous research. This paper initially examines the double nature of the price of gold both as a commodity and money from 1969 to 2014 by a statistics model, namely the Ensemble Empirical Mode...

The random walk hypothesis is rejected for foreign stock market prices. Variance ratio tests are performed on weekly stock prices of nine major foreign stock market indices. While longer-term returns follow random walks, short-horizon, bi-weekly returns exhibit significant positive serial...

Motivated by the growing importance of ancillary revenues in the airline industry, we propose a statistical model for Advanced Seat Reservation (ASR). We focus on the questions of whether, when and which seats are selected by passengers. To answer these questions, we employ a discrete time...

This paper initially analyzes the constitution of gold price by Ensemble Empirical Mode Decomposition (EEMD) with a data span of 1969-2014. We decompose and categorize the change of the gold price by time frequency into three aspects: high frequency portion, low frequency portion and trend...

This paper analyzes whether the market portfolio is efficiently related to benchmark portfolios formed on size, value, momentum and reversal with various utility theories by using stochastic dominance criteria. The results support the prospect theory including assumption of loss aversion at...

Resource misallocation can lower aggregate total factor productivity (TFP).We use microdata on manufacturing establishments to quantify the potential extent of misallocation in China and India versus the United States. We measure sizable gaps in marginal products of labor and capital across...

This paper proposes fully nonparametric tests to detect possible collusion in first-price procurement (auctions). The aim of the tests is to detect possible collusion before knowing whether or not bidders are colluding. Thus we do not rely on data on anti-competitive hearing, and in that sense...
