This paper examines the equilibrium correspondence in Arrow-Debreu exchange economies with semi-algebraic preferences. We show that a generic semi-algebraic exchange economy gives rise to a square system of polynomial equations with finitely many solutions. The competitive equilibria form a...

The Lucas (1978) Tree Model lies at the heart of modern macro-finance. At its core, it provides an analysis of the equilibrium price of a long-lived asset in an exchange economy where consumption is the objective, and the sole purpose of the asset is to smooth consumption through time....

Using a laboratory experiment, we investigate whether comovement can emerge between two risky assets, despite their fundamentals not being correlated. The ‘Two trees' asset pricing model developed by Cochrane et al. (2007) guides our experimental design and its predictions serve as our source...

The balance of macro accounting requires that there are economic entities have opposite preferences and take opposite economic activities like mirror copy (Nshi(2017)). This paper provides examples of uses of the symmetry rule for financial markets.Most important implication of the symmetry...

Using a laboratory experiment, we investigate whether contagion can emerge between two risky assets, even when their fundamentals are not correlated. To guide our experimental design, we use the ‘Two trees' asset pricing model developed by Cochrane et al. (2007). The model makes time-series...

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 provide simple examples to illustrate how wealth-driven selection works in asset markets. Our examples deliver both good and bad news. The good news is that if individual assets demands are expressed as a fractions of wealth to be invested in each asset, e.g. because traders maximize an...

This essay is the second of three. The first is nontechnical and in part autobiographical describing the evolution of my approach to developing a micro economic theory of money and financial institutions. This essay is devoted to a mathematical sketch of a closed economic exchange system with...
