    Wrapping up my first year PhD course today. Had a great time with incredible students! As a huge fan of using flowcharts to represent models (you should try it too it's addictive!), I created one for the textbook New-Keynesian model 🤓

    New paper on recent US tariffs with Matt Rognlie and @a_auclert Our focus: effects of temporary increases in tariffs (“tariff shocks") Three Qs: 1 Will tariffs lead to a recession? 2 Will they reduce the trade deficit? 3 Why are they not appreciating USD? (as in std theory) 🧵

    Recent inflation and consumer spending numbers have remained strong. Why? One idea that people seem to dismiss somewhat: Excess savings “It’s been two years since Biden’s stimulus, everybody already spent it” A short 🧵 on why that is the wrong way of thinking about it... 1/N

    Inflation firmed and consumers stepped up spending in January, likely leaving the Federal Reserve on track to keep raising interest rates on.wsj.com/3YdWgMF

    1/N My very first thread! ... I’d like to use it to explain some new work. Let’s start with a thought experiment: Say all US household debt was refinanced to a 1% lower rate. Would it have an impact on the economy?

    Replying to @ludwigstraub
    How does it stop? One very natural way: Money is earned more and more by richer people who spend it less and less (lower MPCs). @a_auclert Matt Rognlie and I call this the “Trickling Up” effect. The stimulus slowly trickles up the wealth distribution, where it remains. 4/N

    (Toy) models are elaborate stories. Here is the story underlying our recent research, without any math. Maybe it gets you to view the world in a slightly different light :)

    What is saving? The number we "save" in our bank account out of the pay-check is just that - a number in a computer Our hope when we save is that the number means something. But that cannot be taken for granted
