An economy with clean and dirty intermediate inputs may fall into a trap characterized by low environmental quality and low life expectancy, while the others converge to opposite steady states. We propose new strategies towards sustainable growth. They include: (i) taxes (subsidies) imposed on...

When agents are liquidity constrained, two options exist - sell assets or borrow. We compare the allocations arising in two economies: in one, agents can sell government (outside) bonds and in the other they can borrow by issuing (inside) bonds. All transactions are voluntary, implying no...

We introduce an approach for the empirical study of the quantity theory of money (QTM) that is novel both with respect to the specific steps taken as well as the general methodology employed. Empirical studies of the QTM have focused directly on the relationship between the rate of change of the...

Monetary policy is superneutral in an overlapping generations model. Previous authors have argued that superneutrality does not hold in such a setting. However, the standard results rely on the counter-factual premise of helicopter money and are overturned if money creation through open market...

This paper studies banks' liquidity provision in the Lagos and Wright model of monetary exchanges. With aggregate uncertainty we show that banks sometimes exhaust their cash reserves and fail to satisfy their depositors' need of consumption smoothing. The banking panics can be eliminated by the...

The paper models the interaction between risk taking in the financial sector and central bank policy for the case of pure illiquidity risk. It is shown that, when bad states are highly unlikely, public provision of liquidity may improve the allocation, even though it encourages more risk taking...

We study money creation and destruction in today's monetary architecture within a general equilibrium setting. Two types of money are created and destructed: bank deposits, when banks grant loans to firms or to other banks, and central bank money, when the central bank grants loans to private...

We extend previous work on the sustainability of the government's intertemporal budget constraint by allowing for non-linear adjustment of the fiscal variables, conditional on the sign of budgetary disequilibria and the phase of the economic cycle. Further, our endogenously estimated threshold...
