Two key assumptions limit the effectiveness of the credit market in the model.

InKiyotaki’s student Matteo Iacoviello embedded the Kiyotaki-Moore mechanism inside a standard New Keynesian general equilibrium macroeconomic model. That is, borrowers must own a sufficient quantity of capital that can be confiscated in case they fail to repay.

Hence, impatient agents must provide real estate as collateral if they wish to borrow. First, the knowledge of the “farmers” is an essential input to their own investment projects—that is, a project becomes worthless if the farmer who made the investment chooses to abandon it.

This page was ,oore edited on 23 Mayat Moore that shows how small shocks to the economy might be amplified by credit credut, giving rise to large output fluctuations.

Journal of Political Economy. This positive feedback is what amplifies economic fluctuations in the model.


In their model economy, Kiyotaki and Moore assume two types of decision makerswith different time preference rates: Therefore, in equilibrium, lending occurs only if it is collateralized. If for any reason the value of real estate declines, so does the amount of debt they can acquire.

Thus land plays two distinct roles in the model: Extensions [ edit ] The original paper of Kiyotaki and Moore kiyoraki theoretical in nature, and made little attempt to evaluate the quantitative relevance of their mechanism for actual economies.

This feeds back into the real estate market, driving the price of land down further thus, the borrowing decisions of the impatient agents are strategic complements. Kiyotaki a macroeconomist and Moore a contract theorist originally described their model in a paper in the Journal of Political Economy.

The paper also analyzes cases where debt contracts are set only in nominal terms or where contracts can be set in real terms, and considers the differences between the cases. The model assumes that borrowers cannot be forced to repay their debts. Therefore, loans will only be made if they are backed by some other form of capital which can be confiscated in case of default.

Kiyotaki–Moore model

Retrieved from ” https: The “impatient” agents are called “farmers” in the original paper, but should be interpreted as entrepreneurs or firms that wish to borrow in order to finance their investment projects. Second, farmers cannot be forced to work, and therefore they kiyotqki sell off their future labor to guarantee their debts. In other words, loans must be backed by collateral. The original paper of Kiyotaki and Moore was theoretical in nature, and made little attempt to evaluate the quantitative relevance of their mechanism for actual economies.

This collateral requirement amplifies business cycle fluctuations because in a recessionthe income from capital falls, causing the price of capital to fall, which makes jiyotaki less dredit as collateral, which limits firms’ investment by forcing them to reduce their borrowing, and thereby worsens the recession. Structure of the model [ edit ] In their model economy, Kiyotaki and Moore assume two types of decision makerswith mokre time preference rates: Together, these assumptions imply that even though farmers’ investment projects are potentially very valuable, lenders have no way to confiscate this value if farmers choose not to pay back their debts.

Kiyotaki and Moore’s paper considers land as an example of a collateralizable asset.
