This paper considers a dynamic duopoly market with strategic, price setting firms and an infinite set of fully rational, privately informed consumers who enter the market sequentially. I show that there exists a sequential equilibrium in which prices converge to their realized product qualities...

We investigate the welfare consequences of consumer credit regulation in a dynamic, heterogeneous-agent model with endogenous lender market power. We incorporate a decentralized credit market with search and incomplete information frictions into an off-the-shelf Eaton-Gersovitz model of consumer...

Digitalization led to a rapid expansion of loyalty tokens typically bundled as part of product price. An open question is whether issuers are incentivized to make loyalty tokens tradable, raising regulation issues for monetary and banking authorities. This paper argues that an issuer earns more...

We integrate individual power in groups into general equilibrium models. The relationship between group formation, resource allocation, and the power of specific individuals or particular sociological groups is investigated. We introduce, via an illustrative example, three appealing concepts of...

We integrate individual power in groups into general equilibrium models with endogenous group formation. We distinguish between formal power (the say in group decisions) and real power (utility gain from being in groups). Their values will be determined as part of the equilibrium. We find that...

The study analyses the welfare performance of banks' lending services in the Ghanaian banking industry with emphasis on the role of market power and efficiency. We made use of pooled OLS regression with fixed effect model. For robustness, we adopted Prais-Winsten (1954) regression and two-stage...

Should the FTC have allowed Zillow to acquire its foremost rival, Trulia? It is increasingly well-accepted that digital platforms tend toward dominance in their immediately adjacent relevant-product markets. Google, for example, has long held a majority share of the markets for general-search...

A global monopoly supplier country of necessary inputs for the provision of global public goods has an incentive to subsidize these exports. The strategic interdependence in the global public good context reverses the "large country" incentives to manipulate the terms-of-trade. It is optimal for...

I study how (VaR-based) financial constraints affect liquidity and welfare under different structures of the arbitrage industry. When capital is spread across numerous competitive arbitrageurs, financial constraints may impair their ability to provide liquidity, lowering other investors'...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...
