The impact of foldable containers on container fleet management costs in hinterland transport

This paper analyzes the possibility to save container fleet management costs in repositioning empty containers through the use of foldable containers. We model this entire empty container flow as an integer programming problem with different strategies in empty container flow itinerary. The model is used to carry out numerical experiments that optimize the empty container repositioning in the hinterland, where there are serious empty container repositioning problems caused by extremely imbalanced trades. The study finds that foldable containers can substantially save on repositioning costs compared to the use of standard containers.

Asymmetric dynamics in correlations of treasury and swap markets: Evidence from the US market

Using the asymmetric dynamic conditional correlation (A-DCC) model developed by Cappiello et al. (2006), this paper empirically analyzes the conditional correlation between treasury and swap markets from February 9, 2006 to May 31, 2011, and makes two key contributions. First, the dynamics of the conditional correlation of only the 2-year maturity differs from those of other maturities. These patterns might be explained by the fact that a 2-year maturity is easily affected by market forecasts of monetary policy changes by the Federal Reserve Board. Second, the financial crisis dummies (ξ₁) are all negative in particular with significance at the 5% level for 7 year, 10 year, and 30 year maturities. This result indicates that arbitrage transactions between treasuries and swaps have not taken place on a sufficient scale during the financial crisis period. As Ito (2010) points out, market participants have been uncertain about the direction of the monetary policies of these financial institutions.     

Multi-port vs. Hub-and-Spoke port calls by containerships

This paper addresses the design of container liner shipping networks taking into consideration container management issues including empty container repositioning. We examine two typical service networks with different ship sizes: multi-port calling by conventional ship size and hub-and-spoke by mega-ship. The entire solution process is performed in two phases: the service network design and container distribution. A wide variety of numerical experiments are conducted for the Asia–Europe and Asia–North America trade lanes. In most scenarios the multi-port calling is superior in terms of total cost, while the hub-and-spoke is more advantageous in the European trade for a costly shipping company.     

Efficiency,equality, income taxation and the brain drain: A second-best argument

This note conducts a second-best examination of the effect of the brain drain. If the size distribution of income is a welfare objective, lump-sum taxation is unavailable, and an Atkinson-type optimal income tax is used, it is shown that the opportunity to emigrate will create special difficulties for the LDC policy-maker.     

The sampling distributions of the predictor for an autoregressive model under misspecifications

Approximations to the sampling distributions of the predictor are given misspecifying the autoregressive moving average model as an autoregressive model. We deal with both conditional and unconditional distributions for the dependent and independent cases according to whether the sample data used in estimation and in prediction are dependent or not. The bias and mean squared error are easily obtained from these approximations.     

Economic Consequences of Pegging to the Dollar in a Multicurrency World

The paper studies the monetary mechanism of a three-country world where two large countries are engaged in floating exchange rates with each other, and a small country is pegged to one of these large countries. Three countries possess an endogenous wage determination process, so that the choice of exchange-rate regimes has real consequences. This arrangement creates serious difficulties for the small country. The paper evaluates the relative effectiveness of options for the small country, taking account of endogeneity of wage determination. Complete float of the small country and the currency basket pegging both present promising alternatives, but the complete float is likely to be best.     

Implied Default Probability and Credit Derivatives

Recently many kinds of credit derivatives are traded in the market. The default probability implied in the market becomes important to price some credit derivatives. Also it is useful for managing the credit risk because it includes the market information. In this paper we show how to calculate the implied default probability in the default swap market or the defaultable bond market.This paper is developed from author’s master thesis (Matsumoto, 2000), Graduate School of Systems Management, the University of Tsukuba.     

Commodity Taxation and the Effects of Entry: A Case of Variety Preferences

We study the relationship between commodity taxation and the effect of entry with imperfect competition. We develop a simple general equilibrium model with imperfect competition in which consumers have variety preferences. As a result, we see that introducing specific taxes increases social welfare. Furthermore, we show that the optimal tax rule is contrary to the inverse elasticity rule.Acknowledgement We wish to thank two anonymous referees for their helpful comments.
