This study is motivated based on concern from some renowned scholars and central bankers whom have raised the issue of the sustainability of the International Monetary System (IMS). Using the panel data set of four major international currencies, USD, JPY, EUR and GBP from 1973 to 2013 with Pooled Mean Group (PMG) estimator, to re-examine whether Triffin dilemma still exists through investigating the relationship between the reserve share, current account balance and real effective exchange rate. The evidence from the result indicates that Triffin dilemma exists only in the long run, and shows that in the long-run, current account balance is proportionate to the increased real effective exchange rate while varies inversely with the reserve shares. However, the estimation for the short-run is not significant to prove the existence of Triffin dilemma. In addition, we investigated the non-dollar panel sample and found that the international monetary system still suffers from Triffin dilemma even without the dollar. To overcome Triffin dilemma, immediate step such as having currency swap mechanism is recommended. In medium term, a multi-polar Monetary System is suggested, and in the longer time, a supranational currency will be used to replace all the currencies in the world.

본 연구에서는 현대화폐이론(Modern Monetary Theory)의 실증적 타당성을 평가하기 위해 OECD 국가의 연간 패널자료(2000~2022년)를 이용하여 패널 공적분 분석을 수행하였다. 구체적으로 OECD 가입국을 대상으로 주권화폐(sovereign currency) 보유 여부에 따라 국가그룹을 나눈 후, 각 그룹별로 국가부채 또는 재정적자 비율과 국채이자율 간의 장기균형 관계, 즉 공적분 관계를 검정 및 추정하였다. 실증분석 결과를 정리하면 다음과 같다. 통합 평균-그룹(pooled mean-group) 추정법을 통한 패널 공적분 추정 결과, 유로존 또는 고정환율제 그룹과 같은 비주권화폐국에서는 국가부채 및 재정적자 비율이 국채이자율과 장기적으로 유의한 양(+)의 상관관계를 가지는 반면, 비유로존 또는 변동환율제 그룹과 같은 주권화폐국의 경우에는 음(-)의 상관관계를 가지거나 유의한 관계가 나타나지 않았다. 특히 비주권화폐국에서 국가부채 비율은 장기뿐만 아니라 단기적으로도 실질 국채이자율과 유의한 양(+)의 상관관계를 가지는 것으로 나타났다. 이러한 결과는 국가부채 또는 재정적자 비율과 국채이자율 간의 관계에 대한 현대화폐이론의 예측과 부합하는 것이며, 따라서 동 이론의 실증적 타당성을 지지하는 하나의 근거가 될 수 있다.

Variation in demand, natural resource availability, and technological advancement within a country are the main reasons for necessitating export and import activities between nations. Accordingly, this paper aims to analyze the effect of economic openness on Multifactor Productivity (MFP) in selected Asian countries (Vietnam, Thailand, The Philippines, Indonesia, Cambodia, China, Japan, Malaysia, South Korea, and Singapore) based on data for the period 1990-2018. The analysis conducted in the study employed the panel ARDL approach based on the estimation by Pooled Mean Group (PMG), Mean Group (MG), and Dynamic Fixed Effect (DFE). The Hausman test conducted indicates that the PMG estimation is better than that of MG and DFE since it has a higher variability value than the significance value. The results revealed that economic openness is able to elicit significant and positive effects on short-term and long-term MFP growth. In addition, the study established that other variable, such as the number of schooling years, are also able to produce a positive and significant effect on MFP growth in the long term. Since economic openness can impact MFP growth, every country should thus increase its export activities through more capital and worker inputs that will stimulate greater production.
