We confirm that standard time-series models for US output growth, inflation, interest rates and stock market returns feature non-Gaussian error structure. We build a 4-variable VAR model where the orthogonolised shocks have a Student t-distribution with a time-varying variance. We find that in...

This paper evaluates the performance of structural VAR models in estimating the impact of credit supply shocks. In a simple Monte-Carlo experiment, we generate data from a DSGE model that features bank lending and credit supply shocks and use SVARs to try and recover the impulse responses to...

This paper evaluates the performance of a variety of structural VAR models in estimating the impact of credit supply shocks. Using a Monte-Carlo experiment, we show that identification based on sign and quantity restrictions and via external instruments is effective in recovering the underlying...

Using a narrative identification of US tax changes over the post-WWII period, we show that corporate income tax cuts foster R&D spending and innovation, leading to a persistent increase in aggregate productivity and output. In contrast, changes in the average personal income tax rate have mostly...

This paper estimates the impact on the US economy of four types of uncertainty about (i) government spending, (ii) tax changes, (iii) public debt sustainability and (iv) monetary policy. Following a one standard deviation shock, uncertainty about debt sustainability has the largest and most...

Using a narrative identification of tax changes in the United States over the post-WWII period, we document that a temporary cut in corporate income tax rates leads to a long-lasting increase in innovation and productivity, whereas changes in personal income tax rates only have short-term...
