version: September 2011<br><br>This paper is intended to answer why and how innovation activities promoting economic growth may indeed induce economic fluctuations. To this purpose, it adds an adoption lag to an otherwise standard endogenous growth model with expanding product variety. It shows that the...

We investigate the similarities of macroeconomicfluctuations in the Mediterranean basin and their convergence. A model with three geo-political indicators, covering the West, the East and the MENA portions of the Mediterranean, characterizes well the historical experience since the early 1980....

We document three changes in postwar US macroeconomic dynamics: (i) the procyclicality of labor productivity vanished, (ii) the relative volatility of employment rose, and (iii) the relative (and absolute) volatility of the real wage rose. We propose an explanation for all three changes that is...

We introduce rule-of-thumb consumers in an otherwise standard dynamic sticky price model, and show how their presence can change dramatically the properties of widely used interest rate rules. In particular, the existence of a unique equilibrium is no longer guaranteed by an interest rate rule...

This paper investigates the effects of government spending on the real exchange rate and the trade balance in the US using a new VAR identification procedure based on spending forecast revisions. I find that the real exchange rate appreciates and the trade balance deteriorates after a government...

We obtain the following results. (ii) Both supply and demand shocks are important sources of fluctuations; supply prevails for GDP, while demand prevails for employment and information. (ii) Policy matters: Both monetary and fiscal policy shocks have sizeable effects on output and prices, with...

We date turning points of the reference cycle for 19 countries in the Mediterranean, for selected regions, and for the area. Cycles phases are asymmetric, with expansions lasting, on average, much longer than recessions. Cyclical fluctuations are volatile and not highly correlated across...

The newsworthiness of an event is partly determined by how unusual it is and this paper investigates the business cycle implications of this fact. In particular, we analyze the consequences of information structures in which some types of signals are more likely to be observed after unusual...

We examine the relationship between institutions, culture and cyclical fluctuations for a sample of 45 European, Middle Eastern and North African countries. Better governance is associated with shorter and less severe contractions and milder expansions. Certain cultural traits, such as lack of...

We study the effect of the cycle on the health of newborn babies using 30 years of birth-certificate data for Spain. We find that babies are born healthier when the local unemployment rate is high. Although fertility is lower during recessions, the effect on health is not the result of...
