The study provides evidence in favour of the price range as a proxy estimator of volatility in financial time series, in the cases that either intra-day datasets are unavailable or they are available at a low sampling frequency.A stochastic differential equation with time varying volatility of...

This paper studies the causal mechanisms behind persistent poverty. Using original data on Boran pastoralists of southern Ethiopia, we find that heterogeneous and nonlinear wealth dynamics arise purely in adverse states of nature. In favorable states, expected herd grow is quasi-linear and...

This note summarizes a new procedure for generating stochastic simulations in FRB/US, a large-scale estimated general equilibrium macroeconomic model of the U.S. economy, which has been in use at the Federal Reserve Board since 1996. In the first part of this note, we contrast some features of...

Several methods are currently available to simulate paths of the Brownian motion. In particular, paths of the BM can be simulated using the properties of the increments of the process like in the Euler scheme, or as the limit of a random walk or via L2 decomposition like the...
