This paper tried to estimate the pass - through of exchange rate changes to export price of fishery products using export price function. The results are as follows : 1) The variable of fluctuation of exchange rate of Won(equation omitted) to Yen(equation omitted)(variable E2) is more powerful explanatory variable than that of Won to U.S. dollar to explain the fluctiation of export price of fishery products(varible $P_{t}$)- 2) The variable of fish catches(variable K $P_{t}$) is also found to be a statistically significant varible but that of producer price index is not found. 3) The variable E2 have statistically a more influence on variable $P_{t}$ than variable K $P_{t.}$ 4) The estimation shows us that 1% of fluctuation of variable E2 could result in 0.9978% of fluctuation of variable $P_{t.}$

We review research using departures from the law of one price to measure the advent of globalization in Europe and Asia. In an application, we then study the role of distance and time in statistically explaining price dispersion across 32 Swedish towns for 19 commodities from 1732 to 1914. The resulting large number of relative prices (502,689) allows precise estimation of distance and time effects, and their interaction. We find an effect of distance that declines significantly over time, beginning in the 18th century, well before the arrival of canals, the telegraph, or the railway.

국내 배출권 시장에서는 시장안정화 조치 발동에도 불구하고 배출권 가격의 불확실성 문제가 지속적으로 대두되고 있다. 그리고 2021년 10월 정부가 발표한 2030 감축목표 상향안을 고려해볼 때 배출권 가격의 불확실성 완화를 위한 실질적인 대안 마련의 필요성이 높아지고 있다. 본 연구는 배출권 시장의 가격 불확실성 완화 수단인 가격상하한제가 배출량과 감축비용에 미치는 정량적인 영향을 살펴본다. 분석을 위한 주요 시나리오는 탄소세, 배출권거래제, 가격상하한제하 배출권거래제 3가지로 구분되며, 배출량 불확실성을 반영하기 위해 몬테카를로 시뮬레이션을 기반으로 비교 분석하였다. 연구 결과는 다음과 같다: 1) 상하한제 도입 시에는 다른 시나리오 대비 현저히 낮은 감축비용으로 배출목표를 달성할 수 있다. 상향된 감축목표에서는 0.1%의 초과배출이 발생할 수 있으나 상하한 간격이 넓은 경우 안정적인 목표달성이 가능하다. 2) 이월을 제한할수록 감축비용은 상승한다. 이는 이월 제한 정책이 기간 간 효율성을 저해하여 비용효과적인 감축을 어렵게 만들기 때문이다. 3) 상하한제하에서 정부의 배출권 순구매량이 발생해도 순수입은 양이 될 수 있다. 정부는 배출권을 상한가에서 판매하고 하한가에서 구매하기 때문이다.

As an effective means of price discrimination, some suppliers offer trade credit to the distributors in order to stimulate the demand for the product they produce. The availability of the delay in payments from the supplier enables discount of the distributor's selling price from a wider range of the price option in anticipation of increased customer's demand. Since the distributor's lot-size is affected by the demand for the customer, the distributor's lot-size and the selling price determination problem is interdependent and must be solved at the same time. Also, in many common business transactions, the distributor pays the shipping cost for the order and hence, the distributor's ordering cost consists of a fixed ordering cost and the shipping cost that depend on the order quantity. In this regard, we deal with the joint lot-size and price determination problem when the supplier allows delay in payments for an order of a product. The positive effects of credit transactions can be integrated into the EOQ (economic order quantity) model through the consideration of retailing situations, where the customer's demand is a function of the distributor's selling price. It is also assumed that the distributor's order cost consists of a fixed ordering cost and the variable shipping cost. We formulate the distributor's mathematical model from which the solution algorithm is derived based on properties of an optimal solution. A numerical example is presented to illustrate the algorithm developed.

We empirically examine the impact of online auction knowledge and category-specific knowledge on the final price of online auctions. Specifically, we question how the relationship between buying and selling experiences affects the final prices of online auctions. Related to the trust between buyers and sellers, we examine the multiple interactions between a buyer-seller pairand aim to identify how these repeated transactions influence the final price. To contrast these effects with other product related factors, we focus on so called 'common value' auctions of vintage stamps on eBay, in which the ex-post value of the product is the same among participating agents’ perceived value. Online auction of stamps provides a representative setting to examine the relationship between market experience and the auction participation behavior in the common value auction, as it provides the book value of stamp as well as price variation across individual buyers with different expertise levels. Our analysis of over 3000 stamps auctions on eBay indicates a significantly high frequency of buyer-seller (pair) interactions, thus suggesting a 'relationship view' of auctions. The work validates five hypotheses derived from the existing theory in economics, marketing, and information systems. Through the common-value auction data, we find that seller's online auction experience and category-specific experience favor sellers by increasing the final price. However, buyer's online auction experience does not affect the final price, but buyer's category-specific experience favors buyers by decreasing the final price. We find that the trust between two trading parties increases the final price.

본 연구의 목적은 해운실물경기 지수가 국내 해운선사 주가에 미치는 영향을 분석하는 것이다. 분석에 사용된 변수는 한국 H회사의 주가와 해운실물경기 지수인 BDI(Baltic Dry Index), CCFI(China Containerized Freight Index), HRCI(Howe Robinson Containership Index)다. 분석기간은 2012년부터 2015년이며, 해운선사 주가지수, BDI, CCFI, HRCI의 4년간의 주간 데이터를 활용하였다. VAR 모형을 이용하여 CCFI와 HRCI가 국내해운선사의 주가지수에 미치는 영향을 분석하였고, VECM 모형을이용하여 BDI가 국내해운선사의 주가지수에 미치는 영향을 분석하였다. VAR 모형 분석결과, CCFI, HRCI는 주가지수에 부(-)의 영향을 미치는 것으로 분석되었으며, VECM 모형 분석결과, BDI는 주가지수에 부(-)의 영향을 미치는 것으로 나타났다. 해운실물경기지수에 부의(-) 영향을 받은 국내 해운선사는 해운실물경기지수에 부의(-) 영향을 받은 국내 해운선사는 해운시황에 적절한 대응을 하지 못한 것을 의미한다. 따라서 국내 해운기업은 중장기적인 모니터링을 통해 해운시황에 대처하는 전략이 필요하다.

This study was performed with Korean adults to investigate Makgeolli drinking behavior, preference, and perception about Makgeolli and health, as well as Makgeolli complaints and prices. A survey questionnaire was formulated to obtain information on demographic variables, drinking habits, and perceptions about Makgeolli's function, price, and complaints. The questionnaire was distributed to 468 adults living in the capital area. The results are as follows. Makgeolli (16.1%) was third preferred, following Soju (45.1%) and beer (30.7%), and no significant differences were observed by gender and income, but the preference for Makgeolli increased with increasing age (p<0.001). According to the survey, the largest reason both genders drank Makgeolli was that it tastes good. Men preferred Makgeolli for its health effects and cheap price, while women preferred it for the atmosphere while drinking it. Also, older people and those with higher incomes preferred drinking Makgeolli for its health effect rather than its good taste (p<0.001 for each). No significant difference was observed by gender for the question "Do you think that Makgeolli has a health-promoting effect?" Overall, 51% of the subjects gave positive answers and only 5.9% gave negative answers. Significantly, older people and those with a higher income had a higher rate of answering positively to this question. Belching (45.1%) and headache (29.9%) were the most common symptoms among the side effects of drinking Makgeolli. No significant difference was observed by gender or income, but older people had a higher rate of belching and fewer headaches than younger people (p<0.001). Women had a significantly higher rate of perceiving that Makgeolli was cheap than men. Age and income differences did not influence price perception. To the question "What is the ideal price for high quality Makgeolli", 32.1% answered that the present rate (1,000 won) was ideal, and 59.4% answered that a price between 1,000 and 2,000 won was ideal. These results indicate that the high preference for Makgeolli is due to its good taste and health effects. However, belching and headache caused by drinking Makgeolli were the most common complaints and, thus, must be solved. Some opinions indicated that Makgeolli must eliminate its low-quality image, but, according to this survey, most subjects answered that the ideal price of higher-quality Makgeolli should be increased slightly, which would cause price resistance.

Estimating the effects of price increase on a company's sales is important task faced by managers. If consumer has prior information on price increase or expect it, there would be stockpiling and subsequent drops in sales. In addition, consumer can suppress demand in the short run. Above factors make the sales dynamic and unstable. We develop a time series model to evaluate the sales patterns with stockpiling and short term suppression of demand and also propose a forecasting procedure. For estimation, we use panel data and extend the model to Bayesian hierarchical structure. By borrowing strength across cross-sectional units, this estimation scheme gives more robust and reasonable result than one from the individual estimation. Furthermore, the proposed scheme yields improved predictive power in the forecasting of hold-out sample periods.
