• Identifying the Degree of Collusion Under Proportional Reduction

  Staff Working Paper 2017-51 Oleksandr Shcherbakov, Naoki Wakamori

  Proportional reduction is a common cartel practice in which cartel members reduce their output proportionately. We develop a method to quantify this reduction relative to a benchmark market equilibrium scenario and relate the reduction to the traditional conduct parameter.

• Is the Discretionary Income Effect of Oil Price Shocks a Hoax?

  Staff Working Paper 2017-50 Christiane Baumeister, Lutz Kilian, Xiaoqing Zhou

  The transmission of oil price shocks has been a question of central interest in macroeconomics since the 1970s. There has been renewed interest in this question after the large and persistent fall in the real price of oil in 2014–16. In the context of this debate, Ramey (2017) makes the striking claim that the existing literature on the transmission of oil price shocks is fundamentally confused about the question of how to quantify the effect of oil price shocks.

• On the Tail Risk Premium in the Oil Market

  Staff Working Paper 2017-46 Reinhard Ellwanger

  This paper shows that changes in market participants’ fear of rare events implied by crude oil options contribute to oil price volatility and oil return predictability. Using 25 years of historical data, we document economically large tail risk premia that vary substantially over time and significantly forecast crude oil futures and spot returns.
