This paper focuses on the recently developing financial derivatives markets, and examines the usefulness of option prices as an information variable for monetary policy implementation. A set of option prices provides us with information on the entire probability distribution of the future values...

In Japan, the Consumer Price Index (CPI) is widely used as a measure of inflation or the cost of living. The CPI is constructed by using a fixed-weight Laspeyres formula. This formula is used mainly because of its ease of calculation and comprehension, thus limiting the total cost of...

This paper proposes a testable continuous-time term-structure model with recursive utility to investigate structural relationships between the real economy and the term structure of real and nominal interest rates. Under mean-reverting expectation on real output growth and inflation, this paper...

This paper presents a new approach for modeling an optimal debt contract. It examines a competitive contract design in a continuous-time environment with Markov income shocks and costly verifiable information. It shows that an ex ante optimal contract has the form of a debt contract that...

This paper presents a new approach for modeling an optimal debt contract in continuous time. It examines a competing contract design in a continuous-time environment with Markov income shocks and costly veri able information. It shows that an optimal contract has the form of a long-term debt...

This paper proposes a testable continuous-time term-structure model with recursive utility to investigate structural relationships between the real economy and the term structure of real and nominal interest rates. In a representative-agent model with recursive utility and mean-reverting...

The purpose of this paper is to examine narrow banking proposals. First, we survey the narrow banking proposals presented in the United States and Japan, and categorize them by means of two standards: (1) whether safe assets that a narrow bank is allowed to hold are limited to short-term assets,...

We provide an equilibrium asset pricing formula under moral hazard, which is defined as a firm's change of measure that is incontractible, on the assumption of a power utility function and an endogenous riskless rate. Moral hazard distorts asset prices by (1) moving the market price of diffusive...
