 Yeah, it's an interesting question how our research and research in general can contribute to the practice of monetary policy The thing is economics is complicated And it takes us a long time to understand the world that we sketch as scientists and it's simplified dramatically compared to the real world out there and yet still we took years to even understand what's going on this and our model Banks face various constraints their face constraints of having enough cash at hand to pay the depositors in case they come Want to withdraw their face leverage constraints that they can't lever up too much in order to hold bonds the first various other constraints that you know That prevent them from doing certain activities So now model we try to understand these constraints and we try to understand how they interact with monetary policy Then we came to the conclusion of the monetary policy for example injects a lot of liquidity in case banks Needed a lot that sounds banal Then then indeed it can be helped a lot if that if they don't do this then output might drop a lot
