We investigate the hypothesis that macroeconomic fluctuations are primitively the results of many microeconomic shocks, and show that it has significant explanatory power for the evolution of macroeconomic volatility. We define fundamental volatility as the volatility that would arise from an...

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...

I revisit the General Theory's discussion of the role of wages in employment determination through the lens of the New Keynesian model. The analysis points to the key role played by the monetary policy rule in shaping the link between wages and employment, and in determining the welfare impact...

This paper argues that in the presence of intersectoral input-output linkages, microeconomic idiosyncratic shocks may lead to aggregate fluctuations. In particular, it shows that, as the economy becomes more disaggregated, the rate at which aggregate volatility decays is determined by the...
