We introduce noisy information into a standard present value stock price model. Agents receive a noisy signal about the structural shock driving future dividend variations. The resulting equilibrium stock price includes a transitory component — the "noise bubble" — which can be responsible...

We identify government spending news and surprise shocks using a novel identification based on the Survey of Professional Forecasters. News shocks lead to an increase of the interest rate, a real appreciation of US dollar and a worsening of the trade balance. The opposite is found for the...

A structural Factor-Augmented VAR model is used to evaluate the role of "news" shocks in generating the business cycle. We find that (i) existing small-scale VAR models are affected by "non-fundamentalness" and therefore fail to recover the correct shock and impulse response functions; (ii) news...

The contribution of the present paper is twofold. First, we show that in a situation where agents can only observe a noisy signal of the shock to future economic fundamentals, the "noisy news", SVAR models can still be successfully employed to estimate the shock and the associated impulse...

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...

Necessary and sufficient conditions under which a VAR contains sufficient information to estimate the structural shocks are derived. On the basis of this theoretical result we propose two simple tests to detect informational deficiency and a procedure to amend a deficient VAR. A simulation based...

We identify government spending news and surprise shocks using a novel identification based on the Survey of Professional Forecasters. News shocks lead, through an increase of the interest rate, to a real appreciation of US dollar and a worsening of the trade balance. The opposite is found for...

In a situation where agents can only observe a noisy signal of the shock to future economic fundamentals, SVAR models can still be successfully employed to estimate the shock and the associated impulse response functions. Identification is reached by means of dynamic rotations of the reduced...

We investigate the role of "noise" shocks as a source of business cycle fl uctuations. To do so we set up a simple model of imperfect information and derive restrictions for identifying the noise shock in a VAR model. The novelty of our approach is that identification is reached by means of...
