The value of time

This paper investigates, for the first time, the relationship between prices and trading activity in a market where real assets are traded, i.e. in the sale and purchase market for second-hand dry bulk vessels. Investigation of this issue is of interest since the level of trading activity may contain information about the sentiment and the future direction of the prices in the market. Several important conclusions emerge from this analysis. It is found that price changes are useful in predicting trading volume, which suggests that higher capital gains encourage more transactions in the market. Additionally, it seems that volume has a negative impact on the volatility of price changes. More specifically, in contrast to what is reported for financial markets, we find evidence that, in the market for ships, increases in trading activity lead to a reduction in market volatility. This can be explained by the unique underlying characteristics of the market for ships, including thin trading, which imply that increases in trading activity result in price transparency and stability. These findings indicate that practitioners in the market may use the information contained in the level of trading activity so as to guide their market decisions in the sale and purchase market.

The comparison of general cargo ship economic performance by simulation

Cargo ship designs offered by shipbuilders differ in characteristics such as deadweight, speed, fuel consumption and cargo equipment. The best vessel for high freight markets and high fuel prices may not be the best for low freight markets and low fuel prices. A model has been developed to compare by simulation a number of multi-purpose general cargo vessels suitable for the trade of a Turkish shipowner. The model simulates the operation of each vessel under a variety of operating scenarios, e.g. fuel prices and freight profiles over the ships' lives, and estimates the distribution of resulting net present values. The techno-economic simulation model incorporates variables including ship size, speed, first cost, fuel consumption, load factor and port days.

Results are presented for six standard vessels of around 20 000 dwt operating over a long and a short route. Although the ranking of the six varies with assumptions, one design is shown to be superior under most operating conditions.     

Shipping freight derivatives: a survey of recent evidence

In an industry that is characterized by highly volatile prices, seasonality, strong business cycles, cyclicality and capital intensiveness, risk management is extremely important. Ship-owners and charterers face enormous risks, which emanate from fluctuations in freight rates, bunker prices, interest rates, foreign exchange rates and vessel values. These risks substantially affect the interplay between revenue and cost. Modern risk management techniques, involve the use of financial derivatives products, some of which have been developed exclusively for protecting (hedging) against the adverse price fluctuations of the aforementioned sources of risk in shipping. By using derivatives products, ship-owners and charterers can secure (stabilize) the level of their future income or costs and thus reduce uncertainty and unforeseen volatility of their cash-flow. To explore the importance of hedging freight rate risk in shipping operations, a survey of recent empirical evidence that has appeared in economic studies has been conducted. Developments over the past 20 years have been fast, with certain amount of research carried, which has helped to understand better the special features of these derivatives markets. They are all summarized in the current study, which can provide the stepping stone for further work in the area of shipping derivatives and risk management in shipping.

Highly disaggregrated models of seaborne trade. An empirical model for bilateral dry-cargo trade flows in the World economy

The aim of this paper is to estimate an empirical model of bilateral dry-cargo seaborne import flows in the international economy. Seaborne trade elasticities are estimated for the first time, utilizing the Constant Ratio of Elasticities of Substitution Homogeneous/Homothetic (CRESH) function, a function very rarely used in the past. Highly disaggregated data on volumes of seaborne trade, published by the UN, distinguish between five types of cargo according to the type of ship used for its transportation, and 30 trading regions according to the major sea-lancs used by ships internationally. Multistage budgeting is employed to make the problem of estimation tractable. An empirical model for dry-bulk cargo is estimated based on the CRESH function. Estimation of bilateral export price elasticities enables comparison of the degree of competition in each import market over export regions, and amongst import markets themselves. Risk-averse ship owners may utilize such a comparison to operate in world shiplanes with low degree of competition.

Grouper Culture: An Option for Grouper Management in Indonesia

Strong market demand, combined with the high price of live groupers for live food fish, aquarium fish, and grouper farming, has been enticing all participants in the live reef fish trade (LRFT) network in Asian countries to exploit more live groupers, resulting in an alarming situation regarding groupers in the wild. The current destructive fishing methods that are used to catch live groupers, the fishery's potential for overexploitation, and its impact to both fishers and consumers have raised many concerns among environmentalists, live grouper businesspeople, and the grouper fishers on the need to wisely manage the grouper resources in the wild. Introducing grouper culture looks promising as an option for grouper management.     

The dynamic relationships between paper petroleum refining and physical trade of crude oil into the United States

This article examines the relationship between refinery margins traded on paper using petroleum futures (the paper refinery) and the physical trade of crude oil into the US. Computations of a 3:2:1 crack spread were constructed using daily observations of second- and third-nearby unleaded gasoline and heating oil futures contracts traded on the New York Mercantile Exchange (NY MEX) and spot Brent crude oil prices. The crack spread represents the margin between the cost of crude oil feed stock today and the value of the products produced by a refinery in the future. Unit root tests on each of the time series found crack spreads to be stationary while crude oil imports were found to be non-stationary. A s the two series were found to be integrated of different order, cointegration analysis of the two series was not deemed appropriate. Instead, linear relationships between crack spreads and imports were examined using causality tests. It was found that the 2-month 3:2:1 crack spread Granger-causes crude oil imports and that this causality is unidirectional. The significance of these findings lies in the fact that other industries like tanker shipping derive their demand from the demand for, and trade in, petroleum. Crack spreads, therefore, can provide a leading indicator for short term developments in tanker demand. For a chartering manager who has ships on the spot market, crack spreads can help him/her anticipate demand developments and influence vessel deployment and chartering decisions.     

The relevance of international transport costs on food prices: Endogenous and exogenous effects

The paper addresses the problem of transport costs and their influence on food prices for South American imports. While transport does not seem to be in the focus of existing analyses, its impact on food prices might be underestimated and even closely linked to the development of commonly mentioned drivers of food prices. Since transport price formation is a function of demand and supply, drivers of food prices are also expected to impact on transport prices. The authors argue that a number of relevant factors that drive transport costs - and in consequence food prices - can be influenced by policy makers. Based on empirical analysis, the authors explain the functioning of the determinants of transport costs in the segment of international shipping, trying to describe their exogenous and endogenous components. These results are discussed in reference to policy development in the region.

Structure, conduct and performance on the major liner shipping routes 1

Market concentration on the major container shipping routes has the potential to reduce contestability, impede effective competition and, as a consequence, inhibit the positive relationship between trade and economic growth. This development could also hamper the ability of economic regions to realize their respective competitive and comparative advantages. Within this context, the structure-conduct-performance (SCP) framework is used to analyse liner shipping dynamics in the transpacific, Europe-Far East and transatlantic trade routes. The analysis finds no conclusive evidence that either the increased concentration of slot capacity or the attempts by shipping lines to boost potential slot capacity (mainly through collaborative arrangements) lead to improved financial performance. The paper concludes that, despite high and increasing concentration among carriers on each of the trade routes analysed, these markets remain contestable.

Are AIS-based trade volume estimates reliable? The case of crude oil exports

Most global trade statistics in the public domain refer to official customs data, which are not generally available on a micro (individual cargo) level. With the increasing availability and completeness of ship positioning data from the global Automated Identification System (AIS), it is possible to derive more timely and detailed trade statistics for homogeneous commodity groups. The objective of this article is twofold: (1) to compare the accuracy of AIS-derived trade statistics to official customs data in the crude oil market and (2) to add a breakdown of trade by vessel size over time. We find that while AIS-derived data for seaborne crude exports show good alignment with official export numbers in aggregate, there are substantial temporal and geographical differences across countries and time due to the use of pipelines and transshipment in parts of the supply chain. We highlight the challenges in properly structuring and aggregating micro-level cargo data. Our findings are important for the proper derivation of shipping demand from trade data.     

Price and volume dynamics in second-hand dry bulk and tanker shipping markets

The relationship between trading volume, prices and return volatility is thoroughly investigated in different second-hand dry bulk and tanker market segments. The objective is to gain fruitful insight on the sale and purchase market dynamics, and the sensitivity of vessel price movements following the arrival of new information signals in the shipping markets. Contemporaneous relationships are identified between returns and volume, particularly in the markets of handysize and panamax bulks as well as of handysize and aframax tankers. Price changes are found to have an impact on trading volume indicating that expectations to higher capital gains induce increases in trading activity. Volume appears to have a negative impact on the volatility of price changes mainly in the dry bulk market; this may be due to thin trading, limited transaction transparency and absence of vessel price quotes. The empirical findings can contribute to a better understanding of shipping markets’ microstructure and price volatility dynamics by market participants. This, in turn, can be useful for investors who construct their portfolios of real assets with a view to attain superior capital gains, controlling for the underlying investment risk.     

Emission reduction in international shipping—the hidden side effects

In order to curb the trend toward global warming, many technical, operational, and policy options have been proposed to help reduce the emissions from international shipping—the carrier for 80% of the world’s trade. However, these options might not only reduce emissions from shipping activities, but could also have a ripple effect on the whole supply chain of traded goods, as well as on those serving shipping activities. These effects could have both positive and negative impacts, not only on emission reduction, but also on world trade, economic efficiency, and the local environment. While most studies have examined the feasibility of the various options and their potential contribution to emission reduction, their secondary impacts have not been studied. However, failing to take them into account could very well obstruct the implementation of the options. Through a review of existing studies, this article aims to identify and explain some of these previously unexamined secondary effects that are associated with emission reduction in international shipping, point out the problems that will arise if they are ignored, and provide a basis for further detailed research in this area.     

Are there bubbles in the shipping freight market?

ABSTRACT

This paper addresses the reconsideration of price bubbles specific to the shipping freight market based on the method of the Generalized Supremum Augmented Dickey–Fuller (GSADF). This approach offers the opportunity to recognize multiple bubbles and set their corresponding original and final dates. Empirical results reveal that four bubbles existed in the shipping freight market between October 1988 and February 2018 in which freight deviated from fundamental values. Strong demand (especially in China), the supply capacity, crude oil prices and U.S. dollar fluctuations are potential explanations for the first three bubbles. The global financial crisis that burst in 2008 is the major factor results in the last bubble. Hence, we must distinguish the potential reasons of bubbles in different periods and take measures such as promoting economic multipolarization, strengthening the bargaining power of China, building an effective information transfer system, employing financial derivatives and accelerating the consolidation of the shipping industry to alleviate the negative influences on global seaborne trade.
