우리나라 택시산업(産業)에 대한 정부규제(政府規制)는 크게 보아 요금규제(料金規制), 면허규제(免許規制) 그리고 서비스관련규제(關聯規制)로 나눌 수 있다. 정부규제에 의한 문제점으로서는 요금규제(料金規制)에 의한 초과수요(超過需要)의 존재와 제한적인 면허발급제도(免許發給制度)에 의해 발생한 면허에 대한 프리미엄과 이의 배분을 둘러싼 여러가지 비효율(非效率)과 형평(衡平)의 문제(問題)라고 할 수 있다. 우리나라 택시산업(産業)은 비호출방식(非呼出方式)의 노상유객(路上誘客)을 주로 하는 소위 순항식(巡航式)(cruising)시장(市場)이기 때문에 자유경쟁(自由競爭)의 상태에서는 시장정보전달(市場情報傳達)의 불완전성(不完全性)으로 인한 시장실패(市場失敗)의 가능성(可能性)이 존재한다고 할 수 있다. 따라서 이것을 보정(補正)하기 위한 가격규제(價格規制)의 필요성(必要性)은 인정할 수 있으나, 정부에 의한 제한적인 사업면허(事業免許)의 발급(發給)과, 임의적인 증차결정(增車決定) 및 배분방식(配分方式)은 그 정당성(正當性)이 의문시된다고 할 수 있다. 따라서 장기적(長期的)으로 택시에 대한 면허제(免許制)는 폐지되어야 할 것이다. 그러나 택시증차(增車)의 문제는 도시교통혼잡의 문제와 관련이 있으므로, 중(中) 단기적(短期的)으로는 현행의 직접규제방식(直接規制方式)을 개선하여 일정한 자격을 갖춘 출원자(出願者)에게는 일정금액의 공탁금(供託金)만 납부하면 의무적으로 면허를 내어주는 간접규제방식(間接規制方式)으로의 전환을 고려해야 할 것이다. 또한, 태당(台當) 1일(日) 승객회전률(乘客回轉率)의 증가를 통한 승차난완화(乘車難緩和)를 위해 현행(現行) 요금체계(料金體系)를 개선해야 할 것이다.

The rent seeking behavior of monopolistic online platform enterprises against digital contents suppliers is similar to the importing countries transfers the monopoly profit acquired by exporting companies in the imperfectly competitive market through optimal tariffs. If such an optimal tariffs imposing mechanism of importing countries, according to so-called strategic trade policy theories, is applied to the rent-seeking behavior of online platform companies, important insights can be obtained in discussions on regulatory reform. In other words, if an online platform enterprises impose a differentiated fee on each contents-suppliers in a monopolistically competitive markets that pursues contents differentiation through R&D investment, it would reduce the innovation investment by contents suppliers. Nevertheless, profit-maximizing online platform enterprises would not voluntarily give up the discriminatory fee system. Therefore, we would like to propose the introduction of a regulation that can force the introduction of an non-discriminatory fee system for all the contents suppliers.

Uncertainty in the employment market from the COVID-19 created incomplete employment. As a result, job seekers were required to have overqualifications than job requirements. In previous studies, overqualified workers by incomplete employment were not satisfied with their jobs. A representative result is the intention to change jobs. However, within COVID-19, the perceived overqualification of workers will appear differently. This is because in a rapidly increased employment competition environment due to COVID-19, it will appear as loyalty to maintain a stable job. As a result of this study, work experience was the greatest benefit and high risk for office workers. In addition, both the benefits and risks of overqualification affected loyalty. Unlike the negative impact as in previous studies, workers tried to remain stable at work in an unstable employment environment caused by COVID-19.

Previous analyses of deposit-refund systems (hereafter DRS) mosty concerned consumer-paid DRS. While there has been a trend to put more emphasis on the producers' responsibility in recycling, especilly in Europe, and the supplier-paid DRS has been enforced in Korea during the past decade, little attempt has been made to analyse rigorously the nature of the supplier-paid DRS. This paper looks into the effects of the supplier-paid DRS on firm behaviors and profits under the oligopolistic market structure. It is shown that, in the cournot model where firms strategically interact each other, when the deposit rate is high enough, firms' profit increase as the deposit rate rises. Furthermore, where the number of firms are sufficiently large, it can happen that, as the deposit rate increases, both social welfare and firms' profit improve.

The real estate market is a representative imperfectly competitive market. Real estate information is characterized by being collected and utilized in a closed environment, and market participants have to pay a lot of time, effort, and costs to acquire such information. Korea's real estate public data is increasing year by year, but it is scattered by relevant ministries. So it is difficult to search and analyze, and the level of development of the industry using it is low. In the recent 4th industrial revolution, the proptech industry has developed as an industry to efficiently provide necessary information to the real estate market. In this study, based on the case of major companies in the real estate platform field among proptech companies, we looked at the types of information provided to users, and on the contrary, explored ways to utilize the data collected from users. The results of this study are expected to provide theoretical and practical implications for ways to reduce information asymmetry in the real estate market and contribute to the development of the real estate industry.

This paper assesses the tariff reduction on imported wood products that will have impact on the demand for domestic wood products in South Korea, by estimating the Armington substitution elasticities based on the assumption that they are imperfect substitutes. Results indicate that domestic and foreign wood products are far from perfect substitutes to each other. The substitution elasticities in plywood and fiberboard appeared to be high, implying that tariff reduction may have negative effects on those industries. On the contrary, imported and domestic particleboard showed a low substitution elasticity. The decline of fiberboard industry may lead to the decline in forestry since fiberboard is produced mainly by thinned woods supplied from domestic forests. Therefore, effective countermeasures to enhance the competitiveness of wood products industry are needed to cope with the market opening.

최근 전력산업의 구조적인 측면에서는 수직적 형태의 분리 및 경쟁 도입, 그리고 민영화를 통한 효율 증진 등 전력산업 개편이 전세계적으로 이루어지고 있다. 전력산업의 개편 과정에서 전력공급자(ESP)는 불완전한 시장으로 인한 재정적인 위험에 직면한다. ESP가 재정적인 위험에서 근본적으로 벗어나기 위해서는 합리적인 전기 소매 가격의 책정이 필요하다. 본 논문에서는 현재 적용되고 있는 고정 소매 가격제에 대한 문제점을 제시하고 이를 극복하기 위해서 전기 공급 도매 가격의 변동성을 예측함으로써 헤징을 통한 새로운 요금제의 도입의 필요성을 제안하는 것이 본 논문의 목적이다. 본 논문에서 소개될 새로운 요금제인 Critical Peak Pricing(CPP)에서 전기 공급 도매 가격의 변동성의 예측은 CPP 요금을 적용하는데 중요한 역할을 담당하는 지표로 활용된다. CPP 요금을 적용함으로써 ESP의 재정적인 위험을 최소화하고 수요 탄력성이 반영되어 전기 소비자들과의 관계 향상 또한 유도될 수 있다.[4],[6]

This paper develops a simple model to explain the reasons why foreign acquirers pay significantly higher premiums for U.S. target firms than do U.S. buyers. We also provide empirical work on the valuation effect of foreign takeovers and the determinants of the wealth gains of U.S. target shareholders involved in foreign takeovers. The results indicate that target wealth gains are significantly higher in foreign takeovers than in domestic takeovers, after controlling for the wealth effects of payment method, acquisition type, tax status, size and time period of bids. This confirms the valuation effect of foreign takeovers. Furthermore, the results of cross-sectional regression analysis show that the variation in U.S. target wealth gains is explained by extra tax benefits stemming from double tax deductions for acquisition-related interest expenses incurred by foreign acquirers. These findings imply that differential taxation across tax jurisdictions is the main source of the valuation effect of foreign takeovers. In addition, we find that there exists a valuation effect of the nationality of the foreign acquirers. Japanese companies pay significantly higher premiums than do non-Japanese acquirers. The finding also indicates that competition among bidders increases the abnormal returns to U.S. target shareholders in foreign takeovers.

This study aims to make an analysis of the innovation milieu in connection with the agricultural products and distribution system, and suggest policy alternatives for agricultural development and rural community. The decisions on the agricultural management are highly depend on the individual farm household' conditions(labor force or profits) rather than the crop units(JAKMOKBAN) or others. The partnerships of the innovation agents and trust between the individual farm households are considerably weak. From this paper, we suggest as follows to improve the regional agricultural industry and rural community development. The individual farm households need to convert market-oriented production system. And it is more important to enhance the innovation milieu than to enlarge physical infrastructure for agricultural development and rural community.

Korea also plans to introduce Renewable Portfolio Standard (RPS) for strengthening market functions after 2012 as United States and several members of EU countries did. Through the introduction of RPS, it requires energy industry to supply new and renewable energy at fixed rate. Therefore, it will contribute to the distribution of new and renewable energy. This paper analyzed the economic effect of the introduction of RPS using CGE. The summary of the paper on the analysis of the economic effect based on endogenous growth theory under imperfect market competition by using CGE is as follows; Since RPS possibly regulates the amount of new and renewable energy, it can achieve the target amount of new and renewable energy without fail. As achieving the target amount accurately, the distribution of more advanced skills can be expected. However, GDP reduction can occur because investment cost increases due to the requirement of new and renewable energy supply. Therefore, in the long run, it is appropriate to introduce RPS because it contributes to the distribution of new and renewable energy and can be utilized as a new growth engine to encourage economic growth.
