Coherent Patterning of Matter Waves with Subwavelength Localization

We propose the Subwavelength Localization via Adiabatic Passage (SLAP) technique to coherently achieve state-selective patterning of matter waves well beyond the diffraction limit. The SLAP technique consists in coupling two partially overlapping and spatially structured laser fields to three internal levels of the matter wave yielding state-selective localization at those positions where the adiabatic passage process does not occur. We show that by means of this technique matter wave localization down to the single nanometer scale can be achieved. We analyze in detail the potential implementation of the SLAP technique for nano-lithography with an atomic beam of metastable Ne* and for coherent patterning of a two-component 87Rb Bose-Einstein condensate.Comment: 6 pages, 5 figure

The Role of Macroeconomic Fundamentals in Malaysian Post Recession Growth

This study aims to find out the role of macroeconomic fundamentals in Malaysian post recession growth. The selected macroeconomic variables are exports, imports, price level, money supply, interest rate, exchange rate and government expenditure. The technique of cointegration was employed to assess the long run equilibrium relationships among the variables. Then, this study performs the Granger causality tests based on VECM to establish the short run causality among the variables. The long-run cointegrating relationship shown that an increase in exports, government expenditure or depreciation of exchange rate will promote long-term economic growth while increase in inflation, interest rate and imports will tamper the Malaysian economic growth. The results of short-run Granger-causality indicated that price level and government spending Granger-caused economic growth in the short-run. In conclusion, based on the results of long-run and short run analysis, the fiscal policy is probably the most appropriate tool in promoting economic growth in Malaysia during the post recession period

On the Role Exports in the Economic Growth of Malaysia: A Multivariate Analysis

In recent years a number if studies have attempted to examine the export-led Growth hypothesis in the Malaysian context. The evidence is, however mixed and inconclusive. This might be attributed to the fact that previous studies are bivariate in that they only focus on the relationship between exports and economic growth. Therefore, in the present paper we reexamine the relationship between exports and economic growth in the Malaysian context using a multivariate model in which other relevant factors (exchange rate, labor, and capital) are allowed to exert their influence on the two basic variables (exports and economic growth). Our results are supportive of the export-led growth as a short-run phenomenon in Malaysia. Over the long-run, however, our results supports, instead, the internally generated growth hypothesis.

Exports, growth and threshold effects in Africa

The relationship between openness and growth remains a controversial issue in development economics with many studies focusing on the export-growth relationship. This paper examines whether the relationship between exports and growth found in large cross-section studies also holds in the context of African economies. The paper employs threshold regression techniques to examine whether African countries benefit more from exports when they reach a certain level of development or openness. Our results suggest that there is indeed a positive relationship between exports and growth in Africa. The threshold regression analysis also suggests that it is not necessary for a country to reach a certain level of development or to have an existing export base for this relationship to hold, though it is found that the relationship is stronger for countries that experience higher rates of export growth.

Testing export-led growth in India, Pakistan and Sri Lanka using a multivariate framework

Most time-series studies in the area of export-led growth adopt a bivariate framework and neglect the role of terms of trade. Because the terms of trade have an important bearing on export earnings and income, the underlying models of these studies may have been misspecified. This study is the first to adopt a multivariate framework for South Asia as a region; and by including the terms of trade as an additional variable it tries to correct the misspecification bias of earlier studies. The evidence suggests bidirectional causality between real exports and real income in India, export-led growth in Pakistan and a no-causality result for Sri Lanka

Financial Crisis and Intertemporal Linkages Across the ASEAN-5 Stock Markets

The stock indices of five ASEAN countries, namely, Singapore, Malaysia, Indonesia, Thailand and the Philippines have experienced a structural change after mid-1997 due to the Asian financial crisis, and another shift slightly more than a year later when the markets rebounded. Contemporaneous correlation in stock returns is the strongest and Indonesia leads the movements of the other indices during the crisis. The relative influence of foreign shocks is much more felt during the crisis, as seen in the stronger and longer horizon of responses of all the markets. The stock indices are cointegrated before, but not during the crisis. Price feedbacks between the larger markets of Singapore, Malaysia and Indonesia that existed before the crisis disappear once the crisis is over. Short-run linkages of Malaysia with the other markets have weakened after the crisis. With an increase in the degree of exogeneity of its stock market, contemporaneous co-movements with the other markets have reduced and the causal relationships no longer exist.
