These notes provide an intuitive introduction to dynamic programming. The first two Sections, which can be skipped, present the standard deterministic Ramsey model using the Lagrangian approach. Section 3 reformulates the Ramsey problem by means of a Bellman equation, while Section 4 shows how...

How should firms be incentivized to adopt new technologies when the technical merits and spillovers of such technologies are uncertain? We show that, when information is dispersed but exogenous, efficiency can be induced with simple (constant) subsidies. When, instead, firms must also be...

In a setting with dispersed information, monopolistic competition and sticky-prices, a policy authority uncertain about the monetary transmission mechanism reacts prudently to supply shocks. This induces producers to ascribe an excessive importance to their private information when setting...

CESEE banks are reducing foreign funding sources in response to reduced external imbalances, reduced ability to tap international savings, banking group own strategies, initiatives by some regulators, and consistently with uncertainties surrounding the future of the banking union project. In the...

In chapter I, we model monopolistic competition in the spirit of Blanchard and Kiyotaki (1987) and we study the implications of this market structure for the existence of dynamically inefficient equilibria. We show that, with free entry, the presence of some pure profit does not rule out dynamic...

We study information acquisition in a flexible framework with strategic complementarity or substitutability in actions and a rich set of externalities that are responsible for possible wedges between the equilibrium and the efficient acquisition of information. First, we relate the...
