We estimate dynamic conditional correlations of financial asset returns across countries by an array of multivariate GARCH models and analyze spillover effects of the recent US financial crisis on 5 emerging Asian countries. We confirm the existence of financial contagion around the collapse of...

This paper tests the mean reverting property of current account in the financial crisis-affected 5 counties of southeast Asia using nonlinear unit root tests of Park and shintani (2004). Our approach is based on the idea that a conventional unit root test has lower power in detecting the...

We find nonlinear mean-reverting tendencies in Southeast Asian currencies by applying the newly developed nonlinear unit root test by Park and Shintani (2005). First, with the U.S. dollar as the numeraire currency, we find that 63% of the real exchange rates of Southeast Asian currencies turn...

Industrial internet development (IID) and energy-saving and carbon emissions reduction are important driving forces and objective functions of China’s economic transformation and high-quality development. Whether the two policies can achieve a “perfect” implementation effect is critical to...

A Ti-48Al-2Cr-2Nb alloy with uniformly dispersed nano-Y 2 O 3 addition was prepared by selective electron beam melting (SEBM). The effects of beam speed on the defects, microstructure and compressive properties were studied systematically. The Y 2 O 3 morphology gathered and exhibited a feathery...

Short-chain chlorinated paraffins (SCCPs) were listed for elimination under the Stockholm Convention in 2017 due to their persistence and toxicity. Although Canada and other Stockholm signatories have prohibited the manufacture, usage and import of SCCPs since 2013, they can still be detected at...
