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. This positive feedback is what amplifies economic fluctuations in the model.
The model assumes that borrowers cannot be forced to repay their debts. InKiyotaki’s student Matteo Iacoviello embedded the Kiyotaki-Moore mechanism inside a standard New Keynesian general equilibrium macroeconomic model.
Hence, impatient agents must provide real estate as collateral if they wish to borrow. Second, farmers cannot be forced to work, and therefore they cannot sell off their future labor to guarantee their debts.
Therefore, in equilibrium, lending occurs only if it is collateralized. Thus land plays two distinct roles in the model: This collateral requirement amplifies business cycle fluctuations because in a recessionthe income from capital falls, causing the price of capital to fall, which makes capital less valuable as collateral, which limits firms’ investment by forcing them to reduce their borrowing, and thereby worsens the recession.

If for any reason the value of real estate declines, so does the amount of debt mmoore can acquire. Two key assumptions limit the effectiveness of the credit market in the model.

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.
Cyclles Kiyotaki—Moore model shows instead kiyotakk relatively small shocks might suffice to explain business cycle fluctuations, if credit markets are imperfect.
New Keynesian economics Economics models Business cycle theories. 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. In other words, loans must be backed by collateral. 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 credkt the cases.
Structure of the model [ edit ] In their model economy, Kiyotaki and Moore assume two types of decision makerswith different time preference rates: 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. Retrieved from ” https: Moore that shows how small shocks to the economy might kiyptaki amplified by credit restrictions, giving rise to large output fluctuations.
Kiyotaki a macroeconomist and Moore a contract theorist originally described their model in a paper cjcles the Journal of Political Economy.
Journal of Political Economy. Therefore, loans will only be made if they are backed by some other form of capital which can be confiscated in case of default. In their model economy, Kiyotaki and Moore assume two types of decision makerswith different time preference rates: 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.
