We propose a new model for policy analysis of banking crises (or systemic bank runs) based on the monetary framework developed by Lagos and Wright (2005). If banks cannot enforce loan repayment and have to secure loans by collateral, a banking crisis due to coordination failure among depositors...

We construct a search-theoretic model à la Lagos and Wright (2005), that has multiple steady-state equilibria, one of which may be interpreted as a state of financial crisis. The key ingredient is the collateral-secured loan in the decentralized matching market, in which the borrowers must put...

In this paper, I demonstrate that expansionary fiscal policy associated with an increase in public debt can cause a persistent recession. I assume that entrepreneurs have borrowing constraints and that the government issues debt and collects tax from productive entrepreneurs. The government can...

In this paper, I demonstrate that the Laffer curve for a consumption tax increases monotonically and unboundedly in a closed economy in which the supply of one factor of production is fixed. Therefore, in this economy, an arbitrary amount of government debt can be made sustainable by choosing an...

Do large fluctuations arise from small shocks through financial frictions? In previous literature it is shown that a collateral constraint on intertemporal debt for consumption smoothing does not have a quantitatively significant effect on the response of output to unexpected shocks. We...

A news-driven business cycle is a business cycle in which positive news about the future causes a current boom defined as simultaneous increases in consumption, labor, investment, and output. Standard real business cycle models do not generate it. In this paper, we find that a fairly popular...

This paper theoretically examines an imaginary monetary regime in which the private provision of global public goods that reduce greenhouse gases ("emissions reducers," e.g., forests) is enhanced and the public goods are held in the private sector as monetary assets. We consider a monetary...

Kobayashi, Nakajima, and Inaba (2007) show that in the neoclassical business cycle models with collateral constraints, a boom can be generated in response to an optimistic change in expectations on the future state of the economy. They call this business cycle a news-driven cycle. In their...

The US Great Depression and Japan's lost decade in the 1990s are both characterized as persistent stagnations of economies with debt-ridden corporate sectors subsequent to asset-price collapses. We propose a simple model, in which increases in corporate debt (and/or fluctuations in expectations...

The boom-bust cycles such as the episode of the "Internet bubble" in the late 1990s may be described as the business cycle driven by changes in expectations or news about the future. The comovements in consumption, labor, and investment, in response to news about productivity changes in the...
