Evidence suggests little informed giving. To understand this behavior, we examine voluntary provision of a discrete public good with independent private values that can be ascertained at a cost. We find that an individual who considers a smaller contribution is less likely to learn her value,...

The preference between public and private negotiations for a buyer who sequentially visits two sellers is examined. It is shown that the buyer (weakly) prefers private negotiations so as to create strategic uncertainty about the trade history. With substitute goods, such uncertainty is valuable...

We provide a full equilibrium characterization of warm-glow giving à la Andreoni (1989, 1990) by extending the Andreoni-McGuire (1993) algorithm. We then generalize and offer an intuitive meaning to the large-economy crowding-out results by Ribar and Wilhelm (2002). The algorithm indexes...

In many important high-technology markets, including software development, data processing, communications, aeronautics, and defense, suppliers learn through experience how to provide better service at lower cost. This paper examines how a buyer designs dynamic competition among rival suppliers...
