Does Developing Asia Have Too Much Foreign Exchange Reserves? An Empirical Examination
Donghyun Park,Gemma Esther B. Estrada 한국경제연구학회 2010 Korea and the World Economy Vol.11 No.1
Developing Asian countries have accumulated foreign exchange reserves on an unprecedented scale in recent years. There is a growing consensus that Asia’s reserves now substantially exceed the levels required for precautionary purposes ? i.e., self-protection against currency crisis. The central objective of our paper is to informally and formally test whether reserves in developing Asia have in fact reached excessive levels. Informal tests of reserve adequacy based on widely used rules of thumbs such as the Greenspan-Guidotti rule unambiguously indicate the presence of sizable excess reserves. To test for excess reserves more formally, we use panel-data econometric analysis based on Edison (2003). Our estimation results indicate the presence of large and growing excess reserves since 2002. The results of both informal and formal tests thus confirm the popular belief that developing Asia now has excessive foreign exchange reserves. Therefore, the short-run policy challenge for Asian governments is to manage the region’s burgeoning excess reserves more actively and use them more productively. One promising area of future research, brought to the fore by the global financial crisis, is to develop more nuanced measures of reserve adequacy which take into account the possibility of severe negative shocks.

Objectives: In March 2023, an alternative school in the Republic of Korea reported 12 cases of shigellosis. This study aims to analyze the epidemiological characteristics in order to determine the cause of the cluster outbreak of shigellosis and to develop prevention strategies.Methods: This study focused on 12 patients with confirmed Shigella infection and investigated their demographics, clinical features, epidemiology, diagnostics, and antimicrobial susceptibility. Following the identification of Shigella, we conducted follow-up rectal smear cultures to manage patients, implementing isolation and control measures.Results: This study investigated the emergence of multidrug-resistant Shigella following missionary activities in Cambodia, documenting a cluster infection within an alternative school in Daejeon, the Republic of Korea. The outbreak affected 56 participants, resulting in the confirmation of 12 cases. The incidence rates varied by gender and occupation, with higher rates among males and teachers. All 12 cases demonstrated multidrug resistance. Challenges included delayed pathogen confirmation and suboptimal adherence to isolation criteria. The incident prompted revisions in the criteria for isolation release, focusing on symptom resolution. The study underscores the necessity for strengthened surveillance, educational initiatives focusing on prevention in endemic areas, and improved oversight of unlicensed educational establishments.Conclusion: Successful response strategies included swift situation assessment, collaborative efforts, effective infection control measures, and modified criteria for isolation release. Continued surveillance of multidrug-resistant strains is recommended, especially in regions with a high prevalence.

Objectives: The household secondary attack rate (SAR) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an important indicator for community transmission. This study aimed to characterize transmission by comparing household SARs and identifying risk factors during the periods of Delta and Omicron variant predominance in Republic of Korea.Methods: We defined the period of Delta variant predominance (Delta period) as July 25, 2021 to January 15, 2022, and the period of Omicron variant predominance (Omicron period) as February 7 to September 3, 2022. The number of index cases included was 214,229 for the Delta period and 5,521,393 for the Omicron period. To identify the household SARs and risk factors for each period, logistic regression was performed to determine the adjusted odds ratio (aOR).Results: The SAR was 35.2% for the Delta period and 43.1% for the Omicron period. The aOR of infection was higher in 2 groups, those aged 0 to 18 years and ≥75 years, compared to those aged 19 to 49 years. Unvaccinated individuals (vs. vaccinated individuals) and individuals experiencing initial infection (vs. individuals experiencing a second or third infection) had an increased risk of infection with SARS-CoV-2.Conclusion: This study analyzed the household SARs and risk factors. We hope that the results can help develop age-specific immunization plans and responses to reduce the SAR in preparation for emerging infectious diseases or potential new variants of SARS-CoV-2.
