물류산업은 세계의 모든 정부 및 국가기관에 의하여 최고로 인식되고 있는 전략적이고 경제적 이윤추구의 전 세계에 걸친 거대한 산업이다. 싱가포르는 물류산업이 가장 발달하고 최고로 바쁜 항만을 갖고 있는 국가 중의 하나이다. 싱가포르의 강점은 아시아에서 훌륭한 문화여건, 금융과 상업적인 클러스터, 통신 및 운송의 연결성을 가지고 있는 가장 세계화된 도시라는 점이다. 싱가포르는 우수한 물리적인 산업기반 시설의 장점에 의하여 자유경쟁의 이득을 향유하고 있다. 그렇지만 이러한 것들만으로는 싱가포르가 우리들의 경쟁자로서 앞서 있다고 확신하기에는 충분하질 않다. 싱가포르는 적은인구와 지지배후지의 부족 등으로 도전에 직면하고 있어서 배후지를 다른 국가로 이전하고 있다. 싱가포르는 세계 경제 속에서의 국제화 중심이 되거나, 남동아시아 성장에 참여하고 배후지의 결속을 증가시키는 선택을 해야 될 것이다. 따라서 이 논문에서는 싱가포르 물류산업의 전략적 발전을 분석하기 위하여 수리통계학적 방법을 적용하였다.

This paper examines the effect of bargaining power over intermediate goods prices on innovation and economic growth using a Schumpeterian growth model. The notion of "intermediate goods prices" broadly indicates the reward to innovators including innovative SMEs as well as intermediate goods producers that are vertically integrated to big businesses. From this viewpoint, this paper sets up a Schumpeterian growth model that incorporates the market power between final goods producers and intermediate goods producers. The results show that the reduction of intermediate goods prices slows down long-run growth rates as it erodes the reward to innovations. Lower intermediate goods prices decrease marginal productivity of capital and real interest rates. However, the harmful effect of lower profits on innovations outweighs the beneficial effect of lower interest rates. Simulations using Korea's data for various cases show that in all cases the policies that raise the share of intermediate goods producers are as powerful as the R&D subsidy policies in raising growth rates. Therefore, fair trade policies that enable intermediate goods producers-especially SMEs to obtain more fruits of innovations will be helpful for long-run economic growth.

The aim of this study is to evaluate the effects of income-led growth path induced by government and consumption expenditures. Six of Nordic countries, Latin American countries and South Korea are selected for this purpose due to the fact that these countries have been pursuing income-led growth policy for more than the last decade except South Korea. The structural equation is formulated based on the government and consumption expenditures with lagged variable, and the GLMs estimation is employed for empirical analysis. Although the impacts are not overwhelmingly effective, empirical evidence suggests that income-led growth path contributes to stimulate economic activities which are associated with increasing in national income in Nordic countries and South Korea. However, the income-led growth path is quite weakly operated. Furthermore, it is even unstable in Latin American countries. In addition to this, the policy target would rather be focused on middle consumption group than low consumption group. Overall, it would be concluded that the income-led growth policy should be implemented for complementary purpose. And, it also has to be mentioned that sustainable growth may not be achievable by this policy.

In this paper, I makes some critical comments on the temporal single-system interpretation (TSSI) of Marxian value theory. The first concerns the claim that the Fundamental Marxian Theorem (FMT) holds within the TSSI under completely general conditions. Based on the idea that the nominal profit does not well fit the FMT, the TSSI proponents suggest that more relevant for proving the TSSI FMT is the real profit, defined by deflating the output prices. In contrast, I propose a more general approach where three possible concepts of profit are all considered, in which case the result is that whether the FMT holds within the TSSI is indeterminate. Second, the refutation of the Okishio theorem presented in Kliman (1996) is critically examined, focusing on the criticism raised in the literature that the Kliman model ignores the cost-reduction criterion as for the technical change and therefore cannot be considered as an internal refutation of the Okishio theorem. Drawing upon the criticism, I explicitly incorporate the cost-reduction criterion into the Kliman model and show that the continuous labor-saving technical change of the Kliman model is not necessarily cost-reducing and under certain conditions is cost-neutral or cost-raising.

This study proposes that the cultural corporation can be more profitable by adopting the 'Buy-One Give-One' Business Model (BOGO BM) under certain conditions. Specifically, the conditions are that 1) consumers' utility for donating is high enough and 2) the production cost is low enough due to economies of scale or process innovation from employee's intrinsic motivation. We adopt a mathematical model where the demand function is a simple linear function and two companies compete with each other by choosing their quantity of output (the Cournot model). Specifically, we investigate the profitability of the BOGO BM in four situations: 1) a monopolist enjoying reduced cost due to process innovation from employee's intrinsic motivation, 2) a monopolist enjoying reduced cost due to economies of scale, 3) the duopoly with BOGO BM and a general company, 4) the duopoly with two BOGO BM companies. In each situation, BOGO BM can be more profitable than other general companies can under certain conditions.

The long-run equilibrium of an economy is a situation where all firms in the economy realize the condition of 'extra profits = 0'. The conventional partial equilibrium (PE) analysis, which is based on the assumption of 'ceteris paribus', conflicts logically with the long run equilibrium. 'Full industry equilibrium' (FIE) deals with long-run equilibrium in the framework of partial equilibrium; FIE requires the adjustment of more variables than PE. The comparative statics analysis of FIE shows that many results of the conventional PE does not hold. The present paper intends to introduce the background and significance of FIE. In its course, the paper discusses similarities and differences between FIE and the Capital Controversies of the 1960s and 1970s, and highlights the critical and constructive significances of FIE.

The types of cartoon market are classified with publishing cartoon(a cartoon magazine & comics) and webtoon. The revitalization of the cartoon market makes cartoonist create many cartoons. By studying many methods for the revitalization of the cartoon market, this paper argues the expanded methods of comics market which is a sort of publishing cartoon market. The expanded methods of comics market are two kinds, one is the revitalization of the comics market and the other is the creation of the comics market. This paper focuses on Genre-mixed Knowledge-Cartoon in order to extend the cartoon market. Also, After studying the Creation Proceed of cartoon market through Genre-mixed Knowledge-Cartoon, we would like to develope the New Creation Model of Cartoon Market. We selected three case(the Real Estate Agency expressed as Cartoon, Let's find an answer in sided figure blank, miraculous English grammar) for this study. With this, we analyzed the case that the matters for analysis is the essential particulars of plan-publishing-distribution's proceed. As a result, we found out the possibility of new cartoon market's creation through Genre-mixed Knowledge-Cartoon. For that reason, we was able to develop 'the New Creation Model of Cartoon Market through Genre-mixed Knowledge-Cartoon'. This paper provides the possibility about the New Creation Model of Cartoon Market through Genre-mixed Knowledge-Cartoon. With this, we will make many plans for creation of Genre-mixed Knowledge-Cartoons. Therefore, This plans will help cartoonists to create the Genre-mixed cartoons.

본 논문은 급증하는 제주지역의 풍력발전설비의 증가에 따라 제주계통의 안정적 운영을 위하여 제주EMS 기능의 일부인 경제급전프로그램의 개선된 내용을 소개하였다. 풍력발전기의 출력은 수시로 변하고 그 예측이 곤란하여, 소규모 계통인 제주계통의 불안정성을 야기할 우려가 더욱 커지고 있다. 이에, 계통운영자가 제주지역 풍력발전기 변동특성을 고려하여 계통운영을 할 수 있도록 풍력발전량 대비 연계선 및 발전기 예비력을 설정 또는 계산하여, 경제급전 참여 발전기에 대한 발전량을 배분할 수 있도록 개선된 제주EMS의 경제급전프로그램의 개선된 내용을 제시하였다.
