We estimate various SVAR models for the US in order to assess the importance of fundamental shocks in explaining stock price movements. The results show that models using real activity variables place more weight on fundamental shocks than models using dividends or earnings. However, according to all models fundamental shocks became substantially less important during the period 1982-2002 if co...

The main substantive finding of the recent structural vector autoregression literature with a differenced specification of hours (DSVAR) is that technology shocks lead to a fall in hours. Researchers have used these results to argue that standard business cycle models in which technology shocks leads to a rise in hours should be discarded. We evaluate the DSVAR approach by asking the following:...

of Searching for the Causal Structure of a Vector Autoregression Vector autoregressions (VARs) are economically interpretable only when identified by being transformed into a structural form (the SVAR) in which the contemporaneous variables stand in a well-defined causal order. These identifying transformations are not unique. It is widely believed that practitioners must choose among them usin...

In this paper, we estimate government purchase multipliers for a large number of OECD countries, allowing these multipliers to vary smoothly according to the state of the economy and using real-time forecast data to purge policy innovations of their predictable components. We adapt our previous methodology (Auerbach and Gorodnichenko, 2011) to use direct projections rather than the SVAR approac...

In Section 3 we showed that our method can have more power to detect o-eSNPs. Here we discuss its power to detect SNPs whose functional mechanisms have non-regulatory components. For simplicity we again consider only continuous Yi, Gi, and a single SNP Si in the ordinary linear model, where the variables have all been centered. We now consider the outcome model Yi = G T i αG + αSSi + i1, where ...

The present paper analyses the impact of sales promotions on store performance, in the short and long term, from the retailer’s point of view. Relationships among promoted and regular sales in the hypermarkets of a large-scale retail chain of national importance, are investigated by means of a structural vector autoregressive model (SVAR). Statistically significant effects of sales promotions i...
