This paper describes a DSGE model where the extensive margin of activity —the number of varieties available for consumption—, depends on micro-founded decisions of entry and exit in the goods market. Both the extended model and a more conventional version have been estimated with US data...

Entry rates have a negative long-run effect on US regional growth, which contradicts innovation-based growth models. This puzzle is resolved when a model-consistent specification is estimated using per capita entry growth. Evidence supports the Schumpeterian hypothesis of a positive relationship...

This paper provides robust evidence that news shocks about future investment-specific technology (IST) constitute a signicant force behind U.S. business cycles. Extending a recent empirical approach to identifying news shocks, we find that positive IST news shocks induce comovement, i.e., raise...

This paper provides new evidence on the relations between the stock market and consumer behavior in Canada. It differentiates between two channels of stock price transmission: a direct wealth channel that operates through changes in wealth and an indirect consumer confidence channel that affects...

We pursue a novel empirical strategy to identify monetary news shocks and determine their effects on the US economy during the Greenspan-Bernanke era of Federal Reserve Chairmanship. We first construct a monetary policy residual as gap between the observed federal funds rate and a policy rule....

We provide evidence that positive industry-level productivity shocks cause employment to fall in the short run in the UK economy. We use a new UK industry data(over the period 1970-2000), which covers both manufacturing and non-manufacturing industries, and identify productivity shocks using...

The markup in Canada has exhibited non-stationary movements, rising steadily since the early 1990s. This implies the presence of a permanent markup shock which causes the desired markup ratio to shift permanently. It is shown that after a permanent positive markup shock, output, per-capita...

We highlight that a broad class of DSGE models with housing and collateralized borrowing predict a fall in both house prices and consumption following positive government spending shocks. By contrast, we show that house prices and consumption in the U.S. rise persistently after identified...

We evaluate empirical evidence for costs that penalize changes in investment using US industry data. In aggregate models, such investment adjustment costs have been introduced to help account for a variety of business cycle and asset market phenomena. We consider a general adjustment cost...

Recent work based on sticky price-wage estimated dynamic stochastic general equilibrium (DSGE) models suggests investment shocks are the most important drivers of post-World War II US business cycles. Consumption, however, typically falls after an investment shock. This finding sits oddly with...
