摘要 Abstract of the paper	We remove the assumption in Degraba (2013) that the dominant input supplier can charge the monopoly input price at the large market while offering exclusive dealing (ED) contract to manufacturer B at the small market and introduce horizontal differentiation to analyze ED competition between a dominant input supplier and a small rival. We obtain the following interesting results. First, given no ED competition from the small rival, manufacturer B will never accept an ED contract provided by the dominant input supplier. Second, given no ED competition from the dominant input supplier, ED contract offered to manufacturer B by the small rival always accomplishes. Third, the small rival always wins ED competition.
