This paper discusses a liquidity run model where investors optimally decide whether or not to acquire private information. This endogenizes the dichotomy "private information/no private information". The price of the information makes the equilibrium partitioning of the fundamentals two...

In this paper, we present a straightforward economic model that explains the incentives to manipulate nodal energy prices in a “Day 2” RTO market. The model distinguishes between legitimate market participation that increases overall market efficiency and manipulative behavior that distorts...

Can-do options are bespoke option structures listed on Safex and Yield-X. The JSE is the first exchange in the world to list, trade and clear exotic options. The first exotic was listed on 8 January 2007 with the onset of the financial crisis that played out during 2008. The option was on the...

In this article we derive risk-neutral option price formulas for both plain-vanilla and exotic electricity futures derivatives on the basis of diverse arithmetic multi-factor Ornstein-Uhlenbeck spot price models admitting seasonality, while – in order to avoid “information...

This study extends Seck's (1996) approach to investigate the degree of substitutability between equity real estate investment trusts (EREITs) and mortgage real estate investment trusts (MREITs). The variance ratio test and the variance decomposition of forecast errors yield results indicating...

In this paper, we study the problem of European Option Pricing in a market with short-selling constraints and transaction costs having a very general form. We consider two types of proportional costs and a strictly positive fixed cost. We study the problem within the framework of the theory of...

Our research question focuses on how more informatives prices affect operators. Above all, I wonder who are the winners and the losers of the lower risk generated by a higher price informativeness. I study a two-period model with a spot market and a futures market for a commodity. Hedgers are...

Many electricity markets exhibit an oligopolistic structure with market participants whose individual trading activities may shift prices essentially. In this context, the question of how to optimally liquidate an existing electricity futures portfolio over a fixed time horizon under the...

We derive risk-neutral option price formulas for plain-vanilla and exotic electricity futures derivatives on the basis of diverse arithmetic multi-factor Ornstein-Uhlenbeck spot price models admitting seasonality. In these setups, we take additional forward-looking knowledge on future price...

Regulations impose idiosyncratic capital and funding costs for holding derivatives. Capital requirements are costly because derivatives desks are risky businesses; funding is costly in part because regulations increase the minimum funding tenor. Idiosyncratic costs mean no single measure makes...
