#### Market Efficiency of Floating Exchange Rate Systems: Some Evidence from Pacific-Asian Countries

(Elsevier, 2011)

This paper examines the random walk hypothesis (RWH) and the martingale difference hypothesis (MDH) for the Australian dollar and five Asian emerging currencies relative to three benchmark currencies. We use Wright’s (2000) ...

#### A European option general first-order error formula

(Cambridge, 2013)

We study the value of European security derivatives in the Black-Scholes model, when the underlying asset 𝛏 is approximated by random walks 𝛏(𝑛). We obtain an explicit error formula, up to a term of order 𝒪(𝑛⁻³/² ), ...

#### Convergence rate of regime-switching trees

(Elseveir, 2016)

Considering a general class of regime-switching geometric random walks and a broad class of piecewise twice differentiable payoff functions, we show that convergence of option prices occurs at a speed of order 𝒪 (𝑛-ᵝ), ...

#### A Market Efficiency Comparison of Islamic and Non-Islamic Stock Indices

(Taylor & Francis Online, 2015)

This article examines the martingale difference hypothesis (MDH) and the random walk hypothesis (RWH) for nine conventional and nine Islamic stock indices: Asia-Pacific, Canadian, Developed Country, Emerging, European, ...

#### Convergence rate of the binomial tree scheme for continuously paying options

(Université du Québec à Montréal, 2012)

Continuously Paying Options (CPOs) form a very natural class of derivatives for hedging risks coming from adverse movements of a continuously traded asset. We study the rate of convergence of CPOs evaluated under the ...

#### Can High-Order Convergence of European Option Prices be Achieved with Common CRR-Type Binomial Trees?

(Springer, 2015)

Considering European call options, we prove that CRR-type binomial trees systematically underprice the value of these options, when the spot price is not near the money. However, we show that, with a volatility premium to ...

#### Exercisability Randomization of the American Option

(Taylor & Frances Online, 2008)

The valuation of American options is an optimal stopping time problem which typically leads to a free boundary problem. We introduce here the randomization of the exercisability of the option. This method considerably ...

#### Martingale problem for superprocesses with non-classical branching functional

(Elsevier, 2006)

The martingale problem for superprocesses with parameters (𝛏, Ф, 𝑘) is studied where 𝑘(𝒹𝑠) may not be absolutely continuous with respect to the Lebesgue measure. This requires a generalization of the concept of ...

#### Option convergence rate with geometric random walks approximations

(Taylor & Frances Online, 2016)

We describe a broad setting under which, for European options, if the underlying asset form a geometric random walk then, the error with respect to the Black–Scholes model converges to zero at a speed of 1/𝑛 for continuous ...
