Shuttle/Centaur project perspective

The shuttle/Centaur vehicle is being developed as an expendable, cryogenic high energy upper stage for use with the National Space Transportation System (NSTS). The stage is expected to meet the demands of a wide range of users. The shuttle/Centaur will be a modification of the highly successful Centaur stage, used extensively with the Atlas and Titan boosters since 1966 to launch planetary, geosynchronous and Earth orbital missions. The design changes required for use with the NSTS are described. These are primarily related to: (1) tank resizing to take advantage of the orbiter payload bay dimensions; (2) provisions for physically adopting Centaur to the orbiter; and, (3) accommodating safety requirements of the manned NSTS. The expected performance capabilities of two versions of the shuttle/Centaur are also described. The initial version, designated G-prime, is the larger of the two, with a length of about 9.1m (30 ft.). This vehicle will be used to launch the Galileo and International Solar Polar Mission to Jupiter in May 1986

Are Re-Assessing the Evidence of an Emerging Yen Block in North and Southeast Asia

Using weekly observations on 9 Asian currencies from November 1976 to December 2003, we re-examine the evidence of an emerging yen block in North and Southeast Asia. In contrast to previous research that assumes instantaneous adjustment of exchange rates by the region’s Central Banks to variations in the world’s main global currencies, we use a dynamic general-to-specific Newey-West estimation strategy that allows gradual adjustment and calculation of both short and long run equilibrium responses. We find that there is no de facto yen block, but although the US dollar remains dominant throughout the region, the yen’s influence is rising amongst a subset of the currencies, particularly since the Asian crisis of the late 1990s.

Corporate Payout Policy in Japan

This paper examines cash dividends and share repurchases in Japan - discerning between keiretsu and non-keiretsu groupings of firms - during the period 1990 to 2008, a period of extensive Japanese corporate governance reform. As in the United States, share repurchases in Japan have grown strikingly across firm groupings even relative to cash dividends which have also increased. Unlike in the United States, cash dividends remain the dominant form of payout across the groupings of firms in Japan. Despite extensive corporate governance reform, the keiretsu grouping of firms exhibits a comparative reticence to alter its corporate payout policy. In particular, it remains the case that keiretsu firms disburse relatively large amounts of cash, they rely relatively heavily on cash dividends rather than share repurchases, they exhibit a greater tendency to discontinue cash dividend payouts, their payouts are relatively sensitive to earnings and these payouts respond relatively rapidly with respect to earnings. In addition, the cash dividend payouts in keiretsu firms have been relatively concentrated, while these payouts from non-keiretsu firms concentrate increasingly over time. The findings also suggest that larger firms in Japan are more likely to payout and if they decide to do so they tend to payout more. As the level of concentration of ownership in Japanese firms increases the amount of cash dividends disbursed decreases. Privatized firms are more likely to pay cash dividends and if they decide to do so and they are not keiretsu affiliated they tend to payout more.Payout policy, dividends, share repurchases, corporate governance

An Analysis of the EU Emission Trading Scheme

The European Union’s Emissions Trading Scheme (ETS) is the key policy instrument of the European Commission’s Climate Change Program aimed at reducing green- house gas emissions to eight percent below 1990 levels by 2012. A critically important element of the EU ETS is the establishment of a market determined price for EU allowances. This article examines the extent to which several theoretically founded factors including, energy price movements, economic growth, temperature and stock market activity determine the expected prices of the European Union CO2 allowances during the 2005 through to the 2009 period. The novel aspect of our study is that we examine the heavily traded futures instruments that have an expiry date in Phase 2 of the EU ETS. Our study adopts both static and recursive versions of the Johansen multivariate cointegration likelihood ratio test as well as a variation on this test with a view to controlling for time varying volatility effects. Our results are indicative of a new pricing regime emerging in Phase 2 of the market and point to a maturing market driven by the fundamentals. These results are valuable both for traders of EU allowances and for those policy makers seeking to improve the design of the European Union ETS.CO2 prices, EU ETS, Energy, Kyoto Protocol, Weather

Assessing Co-ordinated Asian Exchange Rate Regimes

This study assesses alternative Asian exchange rate regimes and finds short- and long-run currency dynamics more conducive to the possibility of introducing a common peg based on a basket of the European euro, the United States dollar and the Japanese yen than the alternative of re-introducing a United States dollar peg exchange rate regime. Exchange rate systems of 3- 4- and 5- Asian currencies are examined and the dynamics in a set of 4 European currencies prior to the introduction of the Euro provides benchmark evidence. The evidence for an Asian basket peg regime is strengthened when, unlike in prior studies, the long-run parameters are estimated while accounting for generalised autoregressive conditional heteroscedasticity effects.Exchange Rate Regimes, Asia, Currency Pegs, Basket Exchange Rates

Robust Global Stock Market Interdependencies

In this paper, we examine the scope for international stock portfolio diversification, from the viewpoint of a United States representative investor, in regard to both the Asian and theEuropean stock markets. Our findings indicate that despite correlation style evidence to thecontrary, the European stock markets provide a superior long-term diversification opportunity relative to that provided by the Asian stock markets. Hence, a short-term measurement of interdependence appears to be uninformative with respect to the diversification opportunities of investors with longer term investment horizons. In terms of methodology, we adopt common stochastic trend tests, including a common stochastic trend test which accounts for generalised autoregressive conditional heteroskedasticity effects in conjunction with the recursive estimation of these tests to estimate the development of longterm stock market interdependence linkages. Recursively estimated robust correlations between the international stock markets are utilised to reveal the nature of short-term stock market interdependence linkages.Stock Market Linkages, Portfolio Diversification, Correlation, Cointegration

Constructing a Magneto-Optical Trap for Cold Atom Trapping

A magneto-optical trap, or MOT, is a device that traps atoms between three pairs of opposing perpendicular laser beams for cooling the atoms to temperatures near absolute zero. The MOT uses Doppler cooling and a magnetic quadrupole field to trap the atoms; in our case, Rb87 atoms. In the future, the MOT will be used in experiments pertaining to the advancement of quantum computing. In this paper, I explain some of the processes required for construction and operation of the MOT

Dynamics of Equity Market Integration in Europe: Evidence of Changes over time and with events.

This paper examines the integration of European equity markets over the 1985-2002 period using a relatively new cointegrating technique that assesses how the level of integration in equity price levels changes over time. This procedure is supplemented by two other dynamic techniques that also measure the extent of time-varying integration from complementary perspectives. The three methods are in agreement that there has been an increased degree of integration among European equity markets especially during the 1997-98 period. This evidence seems to indicate that despite several years of demonstrating political willingness by European leaders to integrate their economies, it was not until the establishment of the EMU and the ECB during the 1997-98 period that the markets deemed that European integration would in fact occur. The evidence presented in this study also indicates that Frankfurt is the dominant market for equities in Europe.
