Roncaglia's views

the view that stagnation has nothing to do with  the zero lower bound

the sequence based on the supply side  as driver

the view that labour market does not determine income

the sequence based on the demand side  as driver

the era of secular stagnation is  over

Hansen's views on stagnation are still valid

he ECBs monetary policy is not neutral today,  there is room for further easing.

 the era in which inflation and interest rates  are very low  is not over

central banks  should make  further interest rate cuts 

a scenario in which productivity growth is very low 

a scenario in which growth remains strong but inflation falls toward the target rate.

a scenario in which growth remains strong but inflation does not fall toward the target rate.

a scenario in which growth remains weak but inflation does not fall toward the target rate.

the. baseline scenario

Ramey

Summers

Blanchard

Roncaglia

Acemoglu

aggregate demand is the only cause of  inflation

involuntary unemployment is possible

investment depend upon the real interest rate

saving depends upon the real interest rate

money is neutral

production can sometimes fail to be sold

involuntary unemployment is possible

there is never a lack of aggregate demand

aggregate demand generates its own supply

aggregate demand is always less that aggregate supply

Ramey's account of stagnation

the idea  that agents have not perfect knowledge but the price system works

Keynes's 

The metaphor of the rocking horse

Keynes's  General Theory

Summers's analysis of stagnation in the US

relies on the hope that potential output will not increase much

will expose the US to massive risks, including inflation,

will expose the US economy to the danger of recession 

is an orthodox neo-liberal approach

Republican nostalgia for the economy under Trump’s first term

will generate low economic growth

 bail outs in the financial sector to avoid domino effects are justified 

inefficient firms may remain on the market

 fluctuations should not be avoided at all costs

the market process should  be regulated

technological change is not the main source of business cycles

aggregate demand

the amount of technological innovation

the supply side

the creative destruction process

the determinants of structural unemployment
