Rather, we consider a market composed of two segments involving small anonymous and large nonanonymous buyers. While the large buyers can contract with each other and any firm in the market, it is...

Although in these equilibria low quality goods are purchased with positive ...

Based on psychological contract violation theory, we propose that an experience of conflict causes buyers to shift their mindset f...
