We evaluate the macroeconomic effects of long‐term sovereign‐bond purchases by the central bank in an economy that is likely to be characterized by a low equilibrium real interest rate and a non‐negligible probability of hitting the zero lower bound (ZLB) on the monetary‐policy rate. Our analysis is based on simulations of a …

A standard Brownian motion is a random process X = {Xt: t ∈ [0, ∞)} with state space R that satisfies the following properties: X0 = 0 (with probability 1). X has stationary increments. That is, for s, t ∈ [0, ∞) with s < t, the distribution of Xt − Xs is the same as the distribution of Xt − s. X has independent increments. cryptographyfxOnce considered tedious, the field of statistics is rapidly evolving into a discipline Hal Varian, chief economist at Google, has actually called "sexy."
