We study identiÞcation in a class of three-equation monetary models. We argue that these models are typically not identiÞed. For any given exactly identiÞed model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to...

We develop a search-matching model, where firms search for customers (e.g. in form of advertising). Firms use long-term contracts and bargain over prices, resulting in a price mark up above marginal cost, which is pro- cyclical and depends on firms’ relative bargaining power. Product market...
