We argue that it is the number of agents holding market power, rather than the presence of market power itself, that may force Ricardian economies into autarchy. We apply the concepts of monopoly equilibrium by Baldwin (1948) to the model of Cordella and Gabszewicz (1997) to show that,...

Are labels good or bad for consumers and firms? The answer may seem straightforward since labels improve information, yet economic theory reveals situations where their introduction reduces the welfare of at least some market participants. This essay reviews the theoretical literature on labels...

We analyze credence goods markets in the case of two firms. Consumers know that the quality of the good varies but do not know which firm is of high quality. First, we show that the high quality producer may be unable to monopolize the market, or even to survive in some cases, in situations...

The existing literature on credence goods and expert services has overlooked the importance of risk aversion. In this paper we extend a standard expert model of credence goods with verifiable service quality by considering risk-averse consumers. Our results show that the presence of risk...

Assuming a fixed-proportion downstream production technology, partial forward integration by an upstream monopolist may be observed whether the monopolist is advantaged or disadvantaged cost-wise relative to fringe firms in the downstream market. Integration need not induce cost-predation and...

This paper analyses the economic consequences of labeling in a setting with two vertically related markets. Labeling on the downstream market affects upstream price competition through two effects: a differentiation effect and a ranking effect. The magnitude of these two effects determines who...
