The Strength of Weak Commitments: A Theory of Price Preannouncements
研究发现制造商提前公布非约束性参考价格，能作为弱承诺帮助其在供应商谈判中获得更优条件，降低采购成本并提升利润，即使极弱的承诺也效果显著。
Manufacturers often preannounce reference prices for products that have not yet been produced or even developed. These prices are rarely binding, meaning that the manufacturers can make price adjustments in the future, possibly at a cost. In this paper, we argue that price preannouncements can serve as a weak price commitment that, we find, helps the manufacturers secure better deals from their suppliers, thereby lowering their procurement costs and improving their profit. Surprisingly, even an extremely weak price commitment can substantially improve a manufacturer’s profit. On the other hand, when the price commitment is credible enough, the manufacturer forgoes the price preannouncement. Collectively, these results underscore the strategic effects that price preannouncements can have on firms’ marketing decisions. This paper was accepted by Dmitry Kuksov, marketing.
