Relatively little is known about the relationship between taxes and asset prices. Differential tax treatment of assets in the same risk class implies differential pricing. Conversely, the ability of tax-exempt investors to engage in tax arbitrage should drive any pricing differences away. The differential tax treatment of classes of US Treasury securities provides a straightforward setting for the examination of possible tax-effects in asset prices. Using the Cox-Ingersoll-Ross Term Structure Model as our framework, we examine the pricing of US Treasury securities over two distinct tax regimes. Evidence that tax effects are not arbitraged away is presented.

In this study, assume that the stock price obeys the stochastic differential equation driven by mixed fractional Brownian motion, and the short rate follows the Vasicek model. Then, the Black-Scholes partial differential equation is held by using fractional Ito formula. Finally, the pricing formulae of the barrier option are obtained by partial differential equation theory. The results of Black-Scholes model are generalized.

We provide a partial differential equation for European options on a stock whose price process follows a general geometric Riemannian Brownian motion. The existence and the uniqueness of solutions to the partial differential equation are investigated, and then an expression of the value for European options is obtained using the fundamental solution technique. Proper Riemannian metrics on the real number field can make the distribution of return rates of the stock induced by our model have the character of leptokurtosis and fat-tail; in addition, they can also explain option pricing bias and implied volatility smile (skew).

본 연구는 지가산정을 위한 방법론으로 서포트 벡터 회귀분석(SVR)을 이용하여 입지특성에 근거한 산업시설용지의 차등적 가격산정모형을 제시하고자 하였다. 기업의 생산활동을 위한 산업시설용지의 공급가격은 용지부담금, 조성비, 판매 및 관리비, 자본비용 등으로 구성된 조성원가를 바탕으로 책정된다. 그러나 현행 산업시설용지 공급가격 산정방식은 개별적인 용지의 입지여건을 고려하지 않은 채 동일한 가격을 단지 내 모든 용지에 획일적으로 적용하는 불합리성을 내포하고 있다. 따라서 본 연구는 이를 지양하기 위한 방안으로 산업시설용지의 차등적 가격산정모형을 제시하고, 모형의 적정성 및 실무적인 적용가능성을 평가하는 과정으로 이루어진다.

We propose a number of finite difference methods for the prices of a European option under the CGMY model. These numerical methods to solve a partial integro-differential equation (PIDE) are based on three time levels in order to avoid fixed point iterations arising from an integral operator. Numerical simulations are carried out to compare these methods with each other for pricing the European option under the CGMY model.

This paper deals with dynamic optimal pricing for new products by a firm which maximizes the discounted profit stream of it's own in a duopoly. The problem is constructed as differential games and dynamic optimization theory. Cost is assumed to decline as time goes on. A modified customer's choice model is formulated as a diffusion model and we solve a dynamic optimization problem by adopting the diffusion model. Since this paper focus on deriving real prices not showing a time trend, we formulate recursive form equations of costate variables(shadow price) and a simultaneous equation of price. Hence we derive a dynamic optimal pricing model for using in real market. In particular, we construct a dynamic optimal pricing model in the case that there are benefits from not only new subscribers but also previous subscribers. We analyze instant camera market in U.S.A(1976-1985) by utilizing the above model.

In this paper, we investigate a time-dependent double obstacle problem associated with the model of European call option pricing with transaction costs. We prove the existence and uniqueness of a W^2,1_p,loc solution to the problem. We then characterize the behavior of the free boundaries in terms of continuity and values of limit points.

본 논문에서는 점프 항을 포함하는 이자율 기간구조 모형의 채권 가격을 결정하기 위하여 이토의 보조정리(Ito's Lemma)를 적용하여 채권가격편미분방정식(Partial Differential Bond Price Equation; PDBPE)을 유도한다. PDBPE으로부터, 지수함수에 대한 매클로린 급수 (Maclaurin series; MS)와 적률생성함수(moment-generating function; MGF)를 이용하여 채권 가격의 수치해(Numerical Solution; NS)를 구한다. 그리고 몬테 카르로 시뮬레이션(Monte Carlo Simulation; MCS) 기법을 이용하여 채권의 가격을 결정하기 위한 알고리즘을 제안하고, 시뮬레이션 과정을 통하여 채권의 가격을 결정한다. 수치적 분석을 이용한 채권 가격의 NS와 MCS를 이용하여 얻은 채권 가격의 결과를 비교하기 위하여, NS의 값과 MCS의 값의 비율인 상대오차(Relative Error; RE)를 구한다. 이로부터 얻은 RE가 약 2.2%보다 작음을 확인할 수 있고, 이것은 수치적 분석뿐만 아니라 제안한 알고리즘을 이용해도 채권의 가격을 매우 정확하게 예측할 수 있음을 의미한다. 또한, 지수함수에 대한 MS를 이용하여 얻은 채권 가격의 NS가 MGF를 적용하여 구한 채권 가격의 NS보다 상대적으로 오차가 작다는 것을 확인할 수 있다.

Theories related to financial market has received big attention from the statistics community. However, not many courses on the topic are provided in statistics departments. Because the financial theories are entangled with many complicated mathematical and physical theories as well as ambiguously stated financial terminologies. Based on our experience on the topic, we try to explain the rather complicated terminologies and theories with easy-to-understand words. This paper will briefly cover the topics of basic terminologies of derivatives, Black-Scholes pricing idea, and related basic mathematical terminologies.
