Purpose - This study aims to quantify the long tail effect in the digital economy. It also investigates the role of digital platform before and after the COVID-19 pandemic. Design/methodology/approach - We take advantage of a granular data set from one of the biggest digital platforms in Korea. Rather than computing the absolute number of products sold or the Gini coefficient, we estimate the slope of the log-linear relationship of the non-parametric sales distribution. Findings - We find that the use of online food order and delivery services is positively associated with individual restaurant's sales growth. We also document that the long tail effect is increasing over time. Long tail effects are clustered in the cross-section where average revenue per order is high or the restaurant belongs to the top 50% of the sales distribution. Research implications or Originality - The findings may indicate that digital platforms are contributing to the development of the digital economy in Korea. Also, we confirm that digital platforms make it possible for small and sole proprietors to go through the difficulties induced by the COVID-19 pandemic.

Two of the most important topics of the 21st century are ensuring harmony between man and his environment and the emerging long-tail economy in which niche markets are becoming increasingly more important. Since the Industrial Revolution in 17th century, human beings have increasingly exploited the world's natural capital, such as the natural environment and its ecosystems. Now the world is facing limits to sustainable economic growth because of limits to this natural capital. Thus, most countries are beginning to adopt a new development paradigm, the so-called"Green Development Paradigm" which pursues environmental conservation in parallel with economic growth. Recently, the Korean government announced an ambitious national policy of Low Carbon & Green Growth for the next six decades. This is an important step that transforms the existing national policy into a new future-oriented one. The fisheries sector in particular has great potential for making a substantial contribution to this national policy initiative. For example, the ocean itself with its sea plants and phytoplankton has an enormous capacity for fixing carbon, and its vast areas of tidal flats have a tremendous potential for cleaning up pollutants from both the sea and the land. Furthermore, the fishing industry has great potential for the development of fuel-saving biodegradable technologies, and a long-tail economy based on digital technologies can do much to promote the production and consumption of green goods and services derived from the oceans and the fisheries. In order for this potential to be realized, the fisheries authority needs to develop a new green-growth strategy that is practical and widely supported by fishing communities and the markets, taking into account the need for greenhouse gas reduction, conservation of the ocean environment and ecosystems, an improved system for seafood safety, the establishment of strengthened MCS (monitoring control surveillance) system, and the development of coastal ecotourism. In addition, fisheries green policies need to be implemented through a well-organized system of government aids, regulations and compensation, and spontaneous (voluntary) orders in fishing communities should be promoted to encourage far more responsible fisheries.

전자상거래 시장에서 롱테일 경제가 출현함에 따라 80/20 룰로 알려진 파레토 법칙의 일반적인 적용에 의문이 제기되고 있다. 이러한 제품 집중도의 변화는 인터넷 인프라 기반기술 위에 구현된 대량맞춤(mass customization)에서 기인한다고 예측된다. 본 연구는 그루폰과 유사한 소셜 커머스 웹사이트로부터 얻은 실거래 정보를 실증 분석하여 제품 및 고객 집중도를 분석하였다. 분석 결과, 이전 전자상거래 연구와 같이 소셜 커머스에서도 파레토 법칙과 다른 롱테일 패턴이 나타났다. 더욱이 email 또는 SMS를 통한 홍보가 판매 집중도 패턴에 영향을 미치는 것으로 파악되었다. email과 SMS를 통한 홍보는 모두 소셜 커머스 쿠폰 판매를 증가시킬 것이라는 예상과는 달리, SMS 홍보는 쿠폰 전반적으로 판매를 증가시키나, 소량 판매 제품의 경우 email 홍보는 오히려 제품 판매를 감소시키는 결과를 보였다.

The linkages between asset prices and macroeconomic outcomes are long-standing issue to both economists and monetary authorities. This paper explores the impact of asset prices on output and price in China. It focuses on the impacts of asset prices on the low quantiles of GDP gap and high quantiles of price gaprespectively. The main findings are the following: the influence of stock price gap, stock returns, and money growth on the different quantile of GDP gap and price gap are noticeable different, and there are significant impacts on the left tail of GDP gap distribution and on the right tail of price gap distribution. This implies that the results coming from simple regression will underestimate the economic risk imposed by asset price volatility. Moreover, these results also provide the caveat that one should cautiously distinguish the meaning of asset price gap and asset price growth rate and use them, through their contents are similar in some sense. One implication for monetarypolicy is that authority should interpret the relationship between asset prices and macro-economy in wider perspectives, and make the policy decision taking the impacts of asset prices on the tails of economy.

본 연구는 웹의 플랫폼화에 대응하기 위한 서비스 유통 및 소프트웨어 개발방식의 핵심이슈로 '규모의 경제'와 '서비스화'이라는 모순적인 요구를 동시적으로 해결하는 것임을 제시했다. 소프트웨어 관점에서 본 이른바 웹 2.0 시대의 주요한 특징은 웹의 플랫폼화와 롱테일 서비스 시장의 등장이다. 웹이 독립적인 유통채널로 기능하게 되는데, 본 연구는 개발자 및 사용자 커뮤니티를 구축하기 위한 플랫폼전략을 규모의 경제와 상호소통(Interaction)의 관점에서 분석했다. 플랫폼 전략에서 제기된 이슈를 해결하기 위해서는 소프트웨어 개발전략도 오픈소스 커뮤니티를 활용한 레고형 개발이 필요하다. 비용절감과 사용자 채널을 확보하기 위해서는 오픈소스 커뮤니티를 이용한 조직화방식이 필요하고, 고객화된 서 비스의 가격경쟁 력을 확보 하기 위한 레고형 개발 방법이 필요하다.

Following importation of temperate Australian breeds of sheep into Malaysia, it was demonstrated that there was variability in libido and semen productivity. Consequently, a study was conducted to determine the concentration of testosterone and relate it with libido and semen production. A total of 10 rams each of Dorset Horn, Cross of Merino with Border Leicester, Siamese Long Tail, Suffolk and local Malin were used to study the composition of testosterone in the blood plasma of these breeds. The study showed that there was significant difference between the testosterone level of different breeds in Spring and Summer but not in Autumn and Winter. The difference was pronounced in August and January. A significant difference (p > 0.05) was recorded in the testosterone levels of the different breeds during the day where Malin had better libido compared to the other breeds. There was no significant difference between the testosterone levels of the different breeds at night. The testosterone level of Suffolk, however, was elevated throughout the night (2.00 ng/ml and over) which resulted in better libido at night compared to the other breeds.
