Study of International Coordination of Chinese Monetary Policy under Open Economy

Preliminary study is made to the international coordination of national monetary policy under economic globalization and informationalization. This paper uses Game Theory to analyze the operation effect of Chinese monetary policy. It suggests that the maximum effect of Chinese monetary policy can only be achieved by cooperation and coordination with international society.

Non-Symmetry of China’s and US Monetary Policy Spillovers:Theoretical Modelling and Empirical Analysis

This study develops a structural vector autoregression(SVAR)framework to empirically examine the reciprocal transmission channels of monetary policies between China and the United States.The primary objective is to discern potential disparities in the spillover effects of monetary policies and ascertain any contrasting mechanisms underlying these effects across the two countries.Based on our research,it appears that there exists a certain level of non-symmetry in the spillover effects of monetary policy between the two countries.Moreover,this paper provides adequate analysis of disparities in the trade framework,capital control,and financial market operations of both countries in constructing a dynamic stochastic general equilibrium(DSGE)model that incorporates financial frictions for the examination of the theoretical rationale.The empirical findings indicate that China’s monetary policy creates a spillover effect primarily through trade.In China,following an increase in its interest rates,the domestic economic activity will experience a contraction,leading to a decline in both investment and output.Consequently,this will result in a decrease in China’s imports of investment goods from the United States,impacting the output of the US economy.In contrast,the US monetary policy exerts a spillover effect primarily through finance.An increase in interest rates by the United States is associated with a notable outflow of capital from China.This leads to a rise in the financing costs for Chinese firms,consequently diminishing their overall net worth.In light of the financial accelerator effect,corporate external financing risk premium will continue to increase,exacerbating the downward trajectory of China’s output.

DIFFICULTIES CONFRONTED BY ICSID TRIBUNALS IN DECIDING INTERNATIONAL INVESTMENT CORRUPTION CASES AND POSSIBLE SOLUTIONS

The issue of corruption has attracted increasing attention in the study and practice of international investment law during recent years.After taking prudent consideration of the corruption defense invoked by the host states in some international investment arbitration cases involved with corruption,International Center for Settlement of Investment Disputes(ICSID)tribunals accordingly determined the final awards.However,some parts of the arbitral jurisprudence aroused strong criticism,especially with regard to the ICSID tribunals’reasoning that arbitrators have no jurisdiction over corruption-tainted international investments.The ICSID tribunals are legitimately supposed to exercise their jurisdiction and are lawfully obliged to probe into the nature of corrupt activities.The tribunals are strongly expected to adopt a balanced approach in deciding the merits and fairly weighing the obligations,rights,and interests of both disputing parties.It is preferable to strengthen the collaborative interaction between ICSID proceedings and domestic anti-corruption enforcement mechanisms when it comes to combating corrupt international investment activities.Existing international treaties(or specific treaty provisions)on combating corruption in international business transactions and calling for international cooperation,alongside domestic anti-corruption enforcement legislation,have actually laid solid legal foundations for the establishment of such an anti-corruption coordinative mechanism between ICSID and domestic corruption regulatory authorities on the global level.

Proposal for a Coordinated International Institute on Friendshipology

Since becoming an active member of the South Bay Chapter of the US-China Peoples Friendship Association,I have contributed four articles to the Voice of Friendship magazine,a publication of the Chinese People’s Association for Friendship with Foreign Countries.Although the USCPFA focuses on friendship between the US and China,my deeper interest is learning about and

Macroeconomic Rebalancing in China and the G20

The principal challenge facing the world economy is the risk of recurrentfinancial crises. Global macroeconomic imbalances create the conditions for boom-and-bust cycles that are extremely costly for the countries that experience them, and that can affect other nations and the entire world economy as well. The G20 recognizes the importance of these trends, and has committed itself to cooperative measures to reduce imbalances. However, progress has been limited and halting. There are major political obstacles to global macroeconomic policy cooperation, both within countries and among countries. China＇s attempts to rebalance its economy are crucial to broader international financial stability. Its G2O presidency gives China the opportunity to demonstrate that it is willing and able to advance its cooperation with economic partners, and to help lead the rest of the world in this direction.

Improved luminescent properties of SrZn_2(PO_4)_2:Sm^(3+) doped with Li^+, Na^+ and K^+ ions

SrZn2(PO4)2:Sm3+ phosphor was synthesized by a high temperature solid-state reaction in atmosphere. SrZn2(PO4)2:Sm3+ phosphor is efficiently excited by ultraviolet(UV) and blue light, and the emission peaks are assigned to the transitions of 4G5/2-6H5/2(563 nm), 4G5/2-6H7/2(597 nm and 605 nm) and 4G5/2-6H9/2(644 nm and 653 nm). The emission intensities of SrZn2(PO4)2:Sm3+ are influenced by Sm3+ concentration, and the concentration quenching effect of SrZn2(PO4)2:Sm3+ is also observed. When doping A+(A=Li, Na and K) ions, the emission intensity of SrZn2(PO4)2:Sm3+ can be obviously enhanced. The Commission Internationale de l'Eclairage(CIE) color coordinates of SrZn2(PO4)2:Sm3+ locate in the orange-red region. The results indicate that the phosphor has a potential application in white light emitting diodes(LEDs).

High-brightness blue organic light emitting diodes with different types of guest-host systems

We demonstrate high-brightness blue organic light emitting diodes(OLEDs) using two types of guest-host systems. A series of blue OLEDs were fabricated using three organic emitters of dibenz anthracene(perylene), di(4-fluorophenyl) amino-di(styryl) biphenyl(DSB) and 4,4'-bis[2-(9-ethyl-3-carbazolyl)vinyl]biphenyl(BCzV Bi) doped into two hosting materials of 4,4'-bis(9-carbazolyl) biphenyl(CBP) and 2-(4-biphenylyl)-5(4-tert-butyl-phenyl)-1,3,4-oxadiazole(PBD) as blue emitting layers, respectively. We achieve three kinds of devices with colors of deep-blue, pure-blue and sky-blue with the Commission Internationale de L'Eclairage(CIE) coordinates of(0.16, 0.10),(0.15, 0.15) and(0.17, 0.24), respectively, by employing PBD as host material. In addition, we present a microcavity device using the PBD guest-host system and achieve high-purity blue devices with narrowed spectrum.

Organic light emitting devices employing non-doped structure

A kind of efficient non-doped white organic light-emitting diodes(WOLEDs) were realized by using a bright blue-emitting layer of 4,4-bis(2,2-diphenylvinyl)-1,1-biphenyl(DPVBi) combining with red emitting ultrathin layer of [2-methyl-6-[2-(2,3,6,7-tetrahydro-1H,5H-benzo[ij]quinolizin-9-yl)ethenyl]-4H-pyran-4-ylidene]propane-dinitrile(DCM2) and green emitting ultrathin layer of 10-(2-benzothiazolyl)-2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H,5H, 11H(1)-benzopyropyrano(6,7-8-i,j)quinolizin-11-one(C545T) with different thicknesses of 0.05 nm, 0.10 nm and 0.20 nm. For comparing, a doped WOLED was also fabricated, in which C545 T and DCM2 are codoped into DPVBi layer to provide blue, green and red emission for obtaining white emission. The maximum luminance and power efficiency of the doped WOLED are 5 765 cd/m^2 at 16 V and 5.23 lm/W at 5 V, respectively, and its Commission Internationale de l'Eclairage(CIE) coordinate changes from(0.393 7, 0.445 3) at 5 V to(0.300 7, 0.373 8) at 12 V. When the thickness of the ultrathin C545 T layer in non-doped WLEDs increases, the emission luminance increases, but all non-doped devices are in the yellow white region. The device with 0.10-nm-thick C545 T has a maximum efficiency of 15.23 cd/A at 8 V and a maximum power efficiency of 6.51 lm/W at 7 V, and its maximum luminance is 10 620 cd/m^2 at 16 V. CIE coordinates of non-doped WLEDs with C545 T thickness of 0.05 nm, 0.10 nm and 0.20 nm are(0.447 3, 0.455 6),(0.464 0, 0.473 1) and(0.458 4, 0.470 0) at 8 V, respectively.
