This paper proposes a new resource allocation system where overall performance can be improved using production smoothing method. In economic point of view, market price is determined by the market mechanism that is subject to the law of demand and supply. Similarly, agents determine whether to allocate tasks to machines by profit and loss or not. In existing resource allocation system, tasks are exclusively allocated to agents with better manufacturing conditions, because they are evaluated by the only currency. But in the proposed resource allocation system, agents are evaluated by not only a currency but also machine specifications. Hereby, the production smoothing is achieved and we expect to improve system performance In this study, we propose a resource allocation system with consideration of Production Smoothing.

Using the indicators of economic policy uncertainty developed by Baker et al. (2016), this paper investigates the effects of the US economic policy uncertainty on the Korea economic uncertainty as well as Korea-US foreign exchange risk. The key findings are that: (i) the degree of spillovers of policy uncertainty from the US to Korea is considerable but not comparatively high; (ii) the US policy uncertainty plays a stronger and more consistent role in Korean currency risk than Korea policy uncertainty and other macro variables. It implies that the economic policy uncertainty in the US is an important contributor to Korea-US exchange rates.

This paper reviews four different kinds of currency crisis models proposed to explain the Korean crisis of 1997 to examine which model is more relevant to explain the Korean crisis of 2008. According to the author's investigation, the 'Frenkel-Neftci' cycle is more relevant model to interpret the Korean crisis of 2008. In 2008, spreads opened due to, first, high interest rate policy by the Korean government aimed to suppress real estate price increase, and, second, the expectation about exchange rate appreciation, and thirdly stock market returns after recovering the crisis. Then the international capital market catastrophe due to the subprime crises produced the sudden change of expectation of the market participants. Huge capital outflows resulted from the credit crunch in the international capital markets, and the possibility of exchange rate depreciation by the Korean government to promote exports in the course of the global recession.

Serious social problems related to the elderly have appeared in the Gangwon Province because the population in this area is rapidly aging. Gangwon has the highest suicide rate and the highest percentage of single households. In the process of preparing for the super-aging society, Time Bank (TB) System has been actively used in 34 countries, especially in the United States, the United Kingdom, and Japan. In Korea, the Gumi Senior Club has joined this system since 2004. TB is a multilateral exchanged system based on the philosophy that everyone's time is valued equally. Time credits are given to the person who provides social services, such as citizen participation and elderly care. People receive the desired services using time credits or donating them. If this system were applied to the Gangwon Province in accordance with its characteristics, it would help to reduce the elderly's prejudices and manage their diverse health problems. A virtual local currency using IT technologies is needed to boost the regional economy. The elderly's participation in TB is strongly needed.

최근 들어 국가별 다양한 이유로 CBDC (Central Bank Digital Currency)에 대한 연구가 활발하게 진행되고 있다. 아울러 블록체인 기술의 눈부신 발전에 따라 이를 기반으로 한 CBDC 시스템이 주목을 받고 있다. 이러한 배경하에 본 논문에서는 기존 은행권에서 효과적으로 사용할 수 있는 블록체인 기반의 CBDC 시스템을 제안하였다. CBDC의 개발과 상용화를 위한 은행권의 여러 요구사항을 분석하였으며, 이를 바탕으로 호환성, 상호운용성, 프라이버시 측면에서 효과적인 시스템 디자인과 이의 구현 방법을 제시하였다.
