We study the efficiency of competitive markets when people are rationally inattentive. Appropriate amendments of the Welfare Theorems hold if attention costs satisfy an invariance condition, which amounts to free disposal of decision-irrelevant aspects of the state of nature. This condition is...

This paper develops a general equilibrium model of technological adoption in an economy populated by 'satisficing' entrepreneurs whose main objective is to minimise innovative effort while keeping the firm alive. In such an economy, product market competition is shown to have a stimulating...

Schumpeterian growth theory has operationalized Schumpeter’s notion of creative destruction by developing models based on this concept. These models shed light on several aspects of the growth process that could not be properly addressed by alternative theories. In this survey, we focus on...

This paper develops an agency model in which firms can influence their own incentives to provide a non-contractible effort by contracting on other variables (e.g. by committing themselves to some verifiable investment). In such a model the firms' need for outside finance is shown to interact...

This paper develops a framework for evaluating the social returns to infrastructure investments that intensify product market competition. We use a circular model with asymmetric production costs both for incumbent firms and potential entrants, where unit transport cost measures the intensity of...
