Contrasting sharply with a recent trend in DSGE modeling, we propose a business cycle model where frictions and shocks are chosen with parsimony. The model emphasizes a few labor-market frictions and shocks to monetary policy and technology. The model, estimated from U.S. quarterly postwar data,...

A new test is proposed for the weak white noise null hypothesis. The test is based on a new automatic selection of the order for a Box–Pierce (1970) test statistic or the test statistic of Hong (1996). The heteroskedasticity and autocorrelation-consistent (HAC) critical values from Lee (2007)...

We analyse the modifications that occur in indirect inference when a nuisance parameter is not identified under the null hypothesis. We develop a testing procedure adapted to this simulation based estimation method, and detail its use for detecting the threshold effect in threshold moving...

In the 90s, the behaviour of US inflation has been a puzzle for many analysts; for eight years, the unemployment rate remained below 6% without giving rise to a significant acceleration of prices and wages. Once again, both the theoretical and empirical relevance of the Phillips curve has been...
