A large set of covariates, such as supply and demand variables as well as futures market variables, is used to test the impact on the crude oil price. Current price movements are a result of scarce refining capacity and speculators betting on higher price...

in this paper, the random walk hypothesis and the opec oil market efficiency have been examined. the random walk hypothesis states that prices are completely stochastic in nature so that they have 'no memory'. in its weak-form, changes in prices occur stochastically and, as a result, the random walk behavior of prices is usually used to test the weak-form efficiency. in order to study the rando...

Business credit lags GDP growth by about one year. This contributes to high leverage during recessions and slow deleveraging. We show that a model in which firms use risky long-term debt replicates this adjustment of firm debt. In the model, slow-moving has important effects for real activity. High levels issued expansions are only gradually reduced recessions. generates an adverse feedback loo...
