Abstract

Making decisions on prices must be an important task for sellers to stay competitive in on-line markets. Because the emergence of price-comparison web sites led buyers to be more sensitive to the prices, adjusting prices became very important to on-line sellers. This study collected and analyzed the data of prices on computing peripheral devices posted at a popular web site that enabled buyers to compare the prices on the same products. By analyzing the timings of price adjustments among different sellers using Monte Carlo simulation, we explored the possibility of price coordinations among those sellers. The results indicated that online sellers adjusted their prices on a daily basis rather than a weekly basis and the tacit coordination on the price changes was identified.

경쟁이 치열한 온라인 마켓에서의 가격결정은 판매자에게 있어서 매우 중요한 업무이다. 가격비교 사이트의 등장으로 동일한 상품에 대한 소비자들의 가격 민감도가 더 높아졌기 때문에 가격조정의 중요성은 점점 커지고 있다. 본 연구는 온라인마켓에서 시간의 흐름에 따른 판매자들 간의 가격조정 패턴을 분석하고자 하였다. 연구를 위하여 가격비교사이트에 올라온 컴퓨터 주변기기에 대한 가격 데이터를 수집하였다. 그리고 몬테카를로 시뮬레이션을 개발하고 판매자들 간의 가격조정 타이밍이 비슷한지를 분석하여 가격담합의 가능성을 탐색하였다. 분석결과는 판매자들 간의 가격조정 타이밍이 비슷하게 나타나는 가격담합현상을 보였으며, 판매자들 간의 가격의존도가 주 단위가 아닌 일 단위가 더 높다는 것이 발견되었다.
