This paper estimates time-varying and constant hedge ratios, and investigates their performance in reducing freight rate risk in routes 1 and 1A of the Baltic Freight Index. Time-varying hedge ratios are generated by a bivariate error correction model with a GARCH error structure. We also...

Market efficiency tests in developing markets display mixed evidence, in contrast to evidence on developed markets where the null hypothesis seems to be supported. Specifically, previous tests for market efficiency on the index and on samples of stocks traded in the Athens Stock Exchange (ASE)...

This paper investigates the nature of seasonality (determistic and/or stochastic) in dry bulk breight rates, and measures and compares it across freight rates of different vessel sizes (Carpesize, Panamax and Handysize), contract duration (spot, 1-year and 3-year time charters) and market...

Time-varying hedge ratios have been found successful in reducing spot market risk in different commodity and financial futures markets. This article extends the empirical evidence by investigating the same question for a futures market based on services, the Baltic International Freight Futures...

The availability of shipping freight contracts with different duration offers shipowners, operators, and charterers the choice to trade risk and return according to the characteristics that each of these contracts offers on the utility frontier. The aim of this paper is to investigate the...

This paper investigates the issue of market risk quantification for emerging and developed market equity portfolios. A very wide spectrum of popular and widely used in practice Value at Risk (VaR) models are evaluated and compared with Extreme Value Theory (EVT) and adaptive filtered models,...

The International Handbook of Maritime Business is a timely, comprehensive and insightful overview of the key contemporary research issues in maritime business.

The estimation of medium-term market risk dictated by limited data availability, is a challenging issue of concern amongst academics and practitioners. This paper addresses the issue by exploiting the concepts of volatility and quantile scaling in order to determine the best method for...

This article investigates the unbiasedness hypothesis of futures prices in the freight futures market. Being the only market whose underlying asset is a service, it sets it apart from other markets investigated so far in the literature. Cointegration techniques, employed to examine this...
