Since the seminal paper written by Weitzman (1974), the “prices vs. quantities” debate regarding choice of policy instrument under imperfect information and uncertainty has been an ongoing concern for economists, especially in the field of the environment. In this debate, several papers have...

The aim of this paper is twofold. First, we present a new capital budgeting method, called the real rate of return (RRR), which has been developed for solving the inconsistency of the modified internal rate of return (MIRR) with shareholders' wealth maximization when costs of capital differ...

With the increased availability of high-frequency financial market data in recent years, the extraction of “realized” volatility (from intraday squared returns) has led to numerous theoretical developments and empirical applications for a wide range of equity and commodity markets. This...

In this paper, we first provide an empirical evidence of the existence of intraday jumps in the crude oil price series. We then show that these jumps, in conjunction with realized volatility measures, are important in modeling the convenience yield over the 2001–2010 period. Our empirical...

As both speculative and hedging financial flows into commodity futures are expected to link commodity price formation more strongly to equity indices, we investigate whether these processes also create increased correlation amongst the commodities themselves. Considering U.S. oil and gas...

Pricing carbon is a central concern in environmental economics, due to the importance of emissions trading schemes worldwide to regulate pollution. This paper documents the presence of small and large jumps in the stochastic process of the CO2 futures price. The large jumps have a discrete...

We empirically reinvestigate the issue of excess comovement of commodity prices initially raised in Pindyck and Rotemberg (1990) and show that excess comovement, when it exists, can be related to hedging and speculative pressure in commodity futures markets. Excess comovement appears when...
