Explaining the convenience yield in the WTI crude oil market using realized volatility and jumps

Sévi, Benoît - In: Economic Modelling 44 (2015) C, pp. 243-251

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...

Multi-item EOQ model while demand is sales price and price break sensitive

Pal, Brojeswar; Sana, Shib Sankar; Chaudhuri, Kripasindhu - In: Economic Modelling 29 (2012) 6, pp. 2283-2288

In this paper, the authors study a multi-item deterministic EOQ (economic order quantity) model for a vendor when the demand rate of the essential commodities decreases quadratically with increasing sales price and increase exponentially with increasing level of price breaks. A price discount is...

An economic manufacturing quantity model with probabilistic deterioration in a production system

Sarkar, Mitali; Sarkar, Biswajit - In: Economic Modelling 31 (2013) C, pp. 245-252

This paper develops an economic manufacturing quantity (EMQ) model with deterioration and exponential demand in a production system over a finite time horizon under the effect of inflation and time value of money. The production rate is a dynamic variable (varying with time) in a production...
