This paper introduces a dynamical extension to the theoretical framework proposed by Slim (2009), where the author analyzes price formation in illegal markets. We develop a simple model with two regimes that can show a rich variety of dynamic behaviors, such as cyclical or even chaotic...

Using a model of dynamic price competition, this paper provides an explanation from the supply side for the well-established observation that retail prices adjust faster when input costs rise than when they fall. The opportunity of profitable storing for the next period induces competitive firms...

This study investigates the relationship between crude oil price and petrol price, as well as their behavior using daily U.S. price series in the period from January 11, 1988 to May 20, 2011. We find that uni-variate GARCH (1,1) is likely the most suitable model to measure the volatility of...

This paper estimates a bivariate VAR-GARCH(1,1) model to examine linkages between food and energy prices. The adopted framework is suitable to analyse both mean and volatility spillovers, and also allows for possible parameter shifts resulting from four recent events, namely: 1) the 2006 food...

This paper proposes a new volatility model for energy prices explicitly characterized by the supply-demand relationship, which we call a Supply and Demand based Volatility (SDV) model. We show that the supply curve shape of energy in the SDV model produces the characteristics of the volatility...
