In a continuous-time economy with complete markets, we study how the heterogeneity in the individual consumers’ risk tolerance and impatience affects the representative consumer’s risk tolerance and impatience. We derive some formulas, which indicate that the representative consumer’s impatience decrease over time, and whether his risk tolerance increases or decreases over time depends on the s...

This article discusses the microstructure of the U.S. Treasury securities market. Treasury securities are nominally riskless debt instruments issued by the U.S. government. Microstructural analysis is a field of economics/finance that examines the roles played by heterogenous agents, institutional detail, and asymmetric information in the trading process. The article describes types of Treasury...

We present an equilibrium model of a moral-hazard economy with one firm and financial markets, where a stock and bonds are traded. We show that it is optimal for the principal to forbid the agent to trade the stock; that the second-best interest rate is lower than the first-best interest rate; and that the second-best equity premium can be higher or lower than the first best equity premium. We ...

Extensive empirical research has shown that in many markets institutional investors have a significant impact on prices and mitigate its adverse effects through their trading strategies. This paper develops a dynamic model of such thin markets, in which the market structure is one of bilateral oligopoly. The paper demonstrates that market thinness qualitatively changes equilibrium properties of...

A game theoretic approach to the theory of money and financial institution is given utilizing both the strategic and coalitional forms for describing the economy. The economy is first modeled as a strategic market game, then the strategic form is used to calculate several cooperative forms that differ from each other in their utilization of money and credit and their treatment of threats. It is...

I study the optimal architecture of bank supervision in a federal system. A central supervisor gets information about a bank, for instance through stress-testing, and decides whether an on-site examination should be performed by a local or a central authority. Local supervisors have lower inspection costs, but do not internalize crossborder externalities. The optimal degree of centralization de...

How do they work? Major components of the perception and signalling pathway have already been revealed. These include an a/ hydrolase as receptor and a complex of players including a DELLA protein and an F-Box protein. In shoots, a protein named D53 has been shown to be targeted for degradation in the presence of strigolactones and this degradation is required for branch inhibition. The downst...

I examine loan data from Prosper.com—a website which allows borrowers to post loans and for lenders to bid on those loans. The Prosper market somewhat resembles the theoretical model of search, herding, and crowding in a large market described in Berkovich and Tayon (2009). That model predicts that assets with high and low prices have high variance in the difference between price and true value...
