I have already reported about the necessity of international cooperation, our role and measures under the present conditions of private technological exchange in the Japanese and Korean Consulting Engineers Meeting at Taejeon, Korea. Continuously I have been discussing whether we, Japanese ＆ Korean consulting engineers can give technological cooperation and support with the regard to industrial technological development, enhancement of industrial infrastructure, social and economic development. I am focusing on Vietnam which has been in the course of economic development to excess in a sense and this country attracts the world's attention. I probe the possibility of technological cooperation under the cooperation of Japanese & Korean consulting engineers while I introduce the present conditions of Vietnam. In addition Vietnam has become a member of ASEAN officially, and the foreign investment in Vietnam has gotten on the right track. Moreover, the regularization of lawsystem in Vietnam is well under way and they aim at joining advanced nations in the 21st century.

We analyze state-level matching efficiencies in the Indian labor market using stochastic frontier analysis. The key contribution of this research is the estimation of matching efficiencies at the state level because these can be used for a state-level measure of labor market conditions. Next, we explore the relationship between the estimated matching efficiencies and population density, labor market flexibility, and the Ease of Doing Business index, respectively. The results show that matching efficiency is heterogeneous across states with considerable variation in accordance with the regional diversity in India. However, we find that there is little relationship between the estimated matching efficiencies and the labor market conditions of interest, suggesting that other regional diversity affects matching efficiencies across states in India.

Purpose - Since China has been South Korea's biggest export destination, uncertainty shocks originating from it would influence South Korea's exports. This paper evaluates the effects of China's economic policy uncertainty on Korea's exports to explore the transmission channels. Design/methodology - Incorporating endogeneities and nonlinearities, this study employs a quarterly time-varying parameters vector autoregressive model to investigate the relationships between China's economic policy uncertainty and Korea's exports, where the overparameterization due to time-varying specifications is overcome by a novel stochastic model specification search framework. According to previous theoretical studies, this paper assesses two channels, demand shock channel and exchange rate channel, through which foreign uncertainty affects Korea's exports. This paper identifies the primary drivers of Korea's aggregate exports and analyzes the rationales for the time-variant impacts of China's economic policy uncertainty on Korea's exports to China. Findings - Our empirical results reveal that Korea's aggregate exports are less responsive to China's economic policy uncertainty shocks and significantly move together with global demand. In contrast, its bilateral exports to China are highly responsive in a negative and time-variant way. Moreover, Chinese investment is an important channel through which China's economic policy uncertainty affects Korea's exports to China after 2010. Further, the time-variant effects of China's economic policy uncertainty on Korea's exports to China are related to changes in China's foreign trade policies, global economic conditions, and China's degree of economic freedom. Originality/value - Few previous studies touch the effects of external uncertainty shocks on South Korea's exports. This paper attempts to fill this gap and explicitly investigate the impacts of China's economic policy uncertainty on Korea's exports from a time-varying perspective. As Korea is an export-oriented economy, this study provides insights for the Korean government to understand the transmissions of external uncertainty better.

The purpose of the article is to analyze the functioning of economic systems in the context of the development of their potential in a circular economy. It is determined that the functioning of economic systems to ensure their sustainability should meet modern challenges and provide for the formation of competitive institutional architecture, the introduction of structural and regulatory innovations, the transition to an innovative model of development. The specific principles of functioning of economic systems include openness, nonlinearity, multivectority, dynamism, emergence, uncertainty about the development of economic processes. It is substantiated that the linear nature of development and equilibrium are not dominant in the functioning of economic systems, and increasing the level of economic efficiency should go hand in hand with minimizing the activities of enterprises, which necessitates the use of circular economy. The main prerequisites for the transition to a circular economy are analyzed. It is determined that the basic concept of the circular economy involves the development of a system of production and consumption, which is based on processing, reuse, repair, product sharing, change of consumption patterns and new business models and systems. The main elements of the circular economy include: a closed cycle, the use of renewable energy sources, systems thinking. The correlation of the principles of sustainable development and the peculiarities of the application of the circular economy is analyzed. It is determined that the circular economy contrasts with the traditional linear economic model, which is based on the model of "take-do-consume-throw away". The advantages and disadvantages due to the use of the principles of circular economy are given. Based on the study, steps are identified to accelerate the transition from a linear economy to a circular economy.

This paper the profit maximizing order quantity model to the symmetric oligopoly consisting of sellers of a homogeneous product who compete with each other for the same potential buyers. Buyers are classified by type, each selecting an optimal purchase quantity in response to the nonlinear quantity discount pricing schedule given by the sellers. Symmetric equilibrium and the economic quantities that sellers must determine are analysed in a Cournot framework, which explicitly depend on the number of sellers. Economic implications are obtianed from the optimality conditions based on themarket share paraments which are used to characterize the competitior's marketing strategy.

Utilization of the aggregation concept applied in economics has been a traditional way of describing the state of an economic system and of predicting the future economic conditions. In addition, certain aggregate variables have also played a crucial role as indicators of the business cycle. Quick examples would be the price index, the productivity changes, the industrial production index, GNP, and so on. The methods of aggregation could be either simple summations, like GNP, or sophisticated weighted average, like the price index.

This study was designed to examine the effects of housing values on housing satisfaction model. The empirical model of this study was based on the Goulart(1982). Data were collected through questionnaire survey, and the sample consisted of 285 households in Kimhae. Housing values were grouped into four clusters : the health and convenience value, the personal and social value, the location value, and the economic value. The major findings were that 1) the concordance between values and the actual housing conditions contributes significantly to the prediction of housing astisfaction, and 2) the control variables including sociodemographic and economic characteristics and housing values themselves did not directly influence on housing satisfaction.

Purpose: The Korean franchise market has undergone drastic growth in recent years. Followed by expansion of franchise business types, relevant legal matters have diversified. Compared to conventional economic laws that focused on resolving problems related to unfair transactions between franchisors and franchisees, more diverse labor laws have emerged recently due to governance and economic dependencies of franchise structure. However, it was found that the business environment of franchisees and working conditions of franchisee employees have not changed accordingly due to the unique structure of franchise business. Though franchisees are entrepreneurs independent from franchisors, they are still under franchising contract with the franchisors. For instance, employees of franchisees have been exposed to malpractices in regard to pay, time, and other working conditions. These malpractices may show the ineffectiveness of current labor laws. Labor management is an important issue for sustainability of franchise businesses. Negative publicity of franchises generated from violating relevant labor laws may have significant negative impact on overall image of franchised brands. However, franchisors should not hold franchisees fully responsible for legal violations in terms of labor management but strive to prevent relevant risks. Thus, the recent amendment in labor law related to increased minimum wage and reduced worktime have called for more attention to effectively implementing the law. Research design, data, and methodology: This study was conducted through a review of franchise-related laws and various institutions and policies. Results: It is further needed for all parties, including franchisors, franchisees, and franchisee employees, to take collaborative actions to improve working conditions of franchisees. Therefore, this study aims to propose appropriate and effective response plans toward recent changes in the Minimum Wage Act, while strengthening sustainability of franchisors, franchisees, and their employees. Conclusions: The proposal mainly contains plans regarding profit-related aids and profit sharing/cost reduction strategies for franchisees, as well as collective bargaining in the franchisor-franchisee relation. More detailed suggestions are included. Conclusions: This proposal may help franchisors and policymakers develop business plans and policies in improving business conditions of franchisees and working conditions of franchisee employees.
