The paper analyzes the dynamic effects of anticipated price increases of imported raw materials upon two large open economies. It is assumed that the economies have an asymmetric macroeconomic structure on the supply side and are dependent upon a small third country for oil or raw materials...

The endorsement of expansionary fiscal packages has often been based on the idea that large multipliers can contrast rising unemployment. Is that really the case? We explore those issues in a New Keynesian model in which unemployment arises because of matching frictions. We compare fiscal...

Using VAR analysis on US data, we show that unanticipated fiscal expansions boost private consumption and business formation.

We combine a simple agent-based model of financial markets with a standard New Keynesian macroeconomic model via two straightforward channels. The result is a macroeconomic model that allows for the endogenous development of stock price bubbles. Even with such a simplistic comprehensive model,...
