We revisit the issue of multiplicity of equilibria when monetary policy is conducted with either the interest rate or the money supply as the sole instrument of policy. We show that in standard monetary models there are interest rate feedback rules, and also money supply rules, that implement a...

How should monetary and fiscal policy react to adverse financial shocks? If monetary policy is constrained by the zero lower bound on the nominal interest rate, subsidising the interest rate on loans is the optimal policy. The subsidies can mimic movements in the interest rate and can therefore...

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that, in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...

In this paper we extend the classical capacitated single-allocation hub location problem by considering that multiple products are to be shipped through the network. We propose a unified modeling framework for the situation in which no more than one hub can be located in each node. In...

Can both short and long-term interest rates be targeted independently? Can the target of the term structure help solve the problem of multiplicity of equilibria that occurs when only the short rate is targeted? Both questions are addressed, and the answer is yes to both.

In this paper, we derive principles of optimal cyclical monetary policy in an economy without capital, with a cash-in-advance restriction on household transactions, and monopolistic firms that set prices one period in advance. The only distortionary policy instruments are the nominal interest...

It is believed that a common monetary policy in a monetary union will have identical effects on different countries as long as these countries have identical fundamentals. We show that, when there is specialization in production, the terms of trade react to the shock. The transmission mechanism...

This paper addresses a new problem to design a two-echelon supply chain network over a multi-period horizon. Strategic decisions are subject to a given budget and concern the location of new facilities in the upper and intermediate echelons of the network as well as the installation of storage...

In a model with costly financial intermediation and financial disturbances, credit subsidies are desirable, irrespective of how they are financed. They are especially useful when the zero lower bound constraint is reached. They are superior to other credit policies such as direct lending.
