A recent literature has provided empirical evidence that markups are increasing and are heterogeneous across firms. In standard monopolistic competition models, such heterogeneity implies inefficiency even in the presence of free entry. We enrich the standard model of monopolistic competition...

Most economists' instinctive reaction to price controls is that they are harmful. If enforced, they result in shortages and resource misallocation. With weak enforcement they often result in black markets, and high transaction costs. In this paper we assess the pros and cons of rice price...

Market mechanisms in the era of globalization associated with the paradigm of the market economy along with the development of socialist economy, capitalist, or mixed. The market mechanism is a problem when the inefficient allocation of resources, market imperfections, and the cause of economic...

The rules that should govern competition and conduct in banking are currently the topics of spirited debate. This paper proposes a rigorous welfare-theoretic methodology which can provide a unifying focus for a wide range of regulatory and market structure issues in banking. The methodology is...

The rise of online platforms has disrupted numerous traditional industries. A prime example is the short-term accommodation platform Airbnb and how it affects the hotel industry. On the one hand, consumers can profit from Airbnb due to an increased number of choices and lower prices. On the...

We study the design features of disclosure regulations that seek to trigger the green transition of the global economy and ask whether such regulatory interventions are likely to bring about sufficient market discipline to achieve socially optimal climate targets. We categorize the transparency...

Traditional cross-sectional estimates of hedonic price functions theoretically can recover marginal willingness to pay for characteristics, but face endogeneity problems when some characteristics are unobserved. To help overcome such problems, economists have introduced difference-in-differences...

In this paper we analyze the welfare properties of the set of Drèze equilibria for economies with incomplete markets and firms. The well known fact that a Drèze equilibrium need not be constrained Pareto optimal is often attributed to a lack of coordination between firms. We show that there...
