This paper introduces agent heterogeneity, liquidity, and endogenous default to a DSGE framework. Our model allows for a comprehensive assessment of regulatory and monetary policy, as well as welfare analysis in the different sectors of the economy. Due to liquidity and endogenous default, the...

This paper employs a general equilibrium model of imperfect competition and trade in which capital is used to establish firms and labor is used for production. We show that two different types of equilibria may exist, one with factor price equalization and one with different factor prices. When...

We study the welfare properties of a general equilibrium banking model with moral hazard that encompasses incentive mechanisms for bank risk-taking studied in a large partial equilibrium literature. We show that competitive equilibriums maximize welfare and yield an optimal level of banks' risk...

We consider a general equilibrium model where groups operating in a competitive market environment can have several members and make efficient collective consumption decisions. Individuals have the option to leave the group and make it on their own or join another group. We study the effect of...

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...

This study develops a theoretical general equilibrium model to examine optimal externality tax policy in the presence of externalities linked to one another through markets rather than technical production relationships. Analytical results reveal that the second-best externality tax rate may be...

We consider firms and multi-member households operating in a competitive market environment. Households are endowed with resources (commodity bundles) and shares of firm ownership. Household members are characterized by individual preferences, possibly with intra-household consumption...

In a general equilibrium model with online, entertainment and informal sectors employing skill, unskilled, and capital, we show that Covid-19 could cause polarization pushing contact-intensive entertainment industry on the brink of collapse while other two survive. Dual roles of factor-intensity...

We propose a model of "trade" between high income and low-income groups where the rich being scared of the spread of infection hires the poor to engage them in exposure-intensive outdoor activities as workers in the household industry. People who endure hardships and sustain exposure to...

Although firms may face radically different production conditions, this dimension of firm heterogeneity is often overlooked. We model input demand across local factor markets, explicitly considering search costs which explain why firms care about both the price and availability of inputs. The...
