Motivation
• "September and October of 2008 was the worst financial crisis in global history, including the Great Depression." - Ben Bernanke
• Economists agree that the Financial events in 2008 was an unexpected, severe and global incident.
• It had global impacts on stocks prices, trade flows, economic activity among others.
• Unexpected rare negative shocks may cause great impacts on economic activity and turns on additional propagation

But at the time
• When asked about what would be the effects of 2008 turmoil
on Brazilian Economy, Brazilian president at the time, Luis Inacio Lula da Silva, stated in São Bernardo do Campo the following:
• “Lá (nos EUA), ela é um tsunami. Aqui, se ela chegar, vai chegar uma marolinha que não dá nem para esquiar.” link
• “There (in USA), the crisis has a dimension of a tsunami. Here, if it gets here, it will look like a “marolinha” that you can not even surf.” (October 4th, 2008)

Objectives
• We want to test whether U.S downturn had an impact on
Brazilian economic activity, measured by its Industrial Production.
• Analyze if the magnitude can be seen as unusual, that is, if this unexpected shock turns on additional propagation mechanisms.

Counterfactual Analysis
• We have to construct two scenario:
• First scenario with no effect at all on Brazilian economy;
• Second scenario contains the expected effect of a “normal” downturn on Brazilian economy;

Data
• Monthly variables from January 1996 till June 2009.
• Brazilian variables: Industrial production growth (pibra), the base interest rate Selic (rate) and the Public Sector Deficit (psd).
• The exogenous policy variable is the American adjusted industrial production (piusa) and T-bill rate (fed).
• We follow NBER dates for US Business Cycles that estimates the decline of the US economy due to Subprime financial crisis from December 2007 till June 2009.

Empirical Strategy: First Step
• First we evaluate if there Brazilian economy was linked to US
macroeconomic variables before the treatment; • For this task we ran (Hendry and Doornik, 2014):
• General Unrestricted Model has 12 lags of each variable

• In the second step we test the hypothesis that Brazil was not
affected at all by US downturn;
• We ran the policy effectiveness test to evalutate for the period from from December 2007 till June 2009;

pre-intervention structure remained stable after the intervention;

The aftermath of Brazilian downturn:
• We estimate that Brazilian Industrial Production drop by
nearly -9.34% on year rate basis from 2007M12 till 2009M6 using Pesaran and Smith (2014) methodology.
• Rejecting the null hypothesis means that there was a structural break in Brazilian DGP;
• Our counterfactual of no contagion suggests that the loss of -6,34% on an annual rate..

• Brazilian production index is linked to US macroeconomic
variable in the period previous to 2007;
• There is evidence that Brazil was affected by US downturn in the period from 2007M12 till 2009M6;
• We collect evidence that financial turmoil of 2008 turned on additional propagation mechanism on Brazilian economy activity.
