Background• Want to Construct a Dynamic Economic Model Useful for the Analysis of

Monetary and Fiscal Policy in a Large Economy Such as the Euro Area or U.S.

2

...


Monetary and Fiscal Policy in a Large Economy Such as the Euro Area or U.S.• Would Like a Model That Can be Used to:

– Identify the Fundamental Shocks Driving Historical Data

3

...



– Identify the Fundamental Shocks Driving Historical Data– Identify the Mechanisms Responsible for Propagating the Shocks

4

...



– Identify the Fundamental Shocks Driving Historical Data– Identify the Mechanisms Responsible for Propagating the Shocks– Serve as a Laboratory For Evaluating Alternative Strategies for Responding

to Shocks.

to Shocks.• We Expand a Standard Monetary Business Cycle Model to Incorporate

Multiple Shocks, Financial Frictions and a Banking Sector.

6

...





Multiple Shocks, Financial Frictions and a Banking Sector.• We Use our Model to Address one of the Biggest Policy Questions:

7

...






– What Shocks Caused the US Great Depression?

8

...






– What Shocks Caused the US Great Depression?– What Mechanisms Propagated the Shocks?

9

...






– What Shocks Caused the US Great Depression?– What Mechanisms Propagated the Shocks?– Could the Monetary Authorities have Mitigated the Severity of the Great

Depression By Reacting in a Different Way to the Shocks?

The Data• GNP Falls Over 30%, 1929 to 1933• Investment:

– Falls 80%– I/Y Goes From 0.25 (P) to 0.06 (T)

• Consumption:– Falls 25%– C/Y initially rises from 0.68 in 1929IV to 0.77 in 1931IV and then falls

back to 0.68 in 1933IV• Employment: Drops Less than GNP (i.e., Productivity Falls) and Never Fully

Recovers• Price Deflator: Drops and Never Fully Recovers

45

...

The Data, cont’d• What Started It?

– Was it the Fed?– Probably Not (Note: M1/P Roughly Constant, R Drops)– Whatever it Was, it was Something that Hit Investment Hard

• Stock Prices Collapsed: Was that What Hurt Investment?• ‘Flight to Quality’: Banks Accumulate Reserves, Households Accumulate

Currency• General Economic Uncertainty: Rises Big Time Starting 1931, With Bank

Panics.• Real Wage Rose Continually: A Reason for the Long Duration of the

Depression?

46

...

Model Features Suggested by Examination of Data• Need a Good Model of:

– Investment,– Employment,– Market Power, Especially for Labor Suppliers.
