As extensions to the Black-Scholes model with constant volatility, option pricing models with time-varying volatility have been suggested within the framework of generalized autoregressive conditional heteroskedasticity (GARCH). However, application of the GARCH option pricing model has been hampered by the lack of simulation techniques able to incorporate early exercise features. In the presen...

Abstract This paper presents a two-country DSGE model with state-dependent pricing as in Dotsey, King, and Wolman (1999) in which firms price-discriminate across countries by setting prices in local currency. In this model, a domestic monetary expansion has greater spillover effects to foreign prices and foreign economic activity than an otherwise identical model with time-dependent pricing. In...

Assessing risk assets is one of the most important research issues in the financial field. There are various pricing models of capital assets in financial. In many models, it is not possible to consider a lot of restrictions on portfolio selection. In this paper, for choosing optimal portfolios, taking into account the prosperity and recession periods, and the types of investors in terms of ris...

In this paper, verification of real-time pricing systems of electricity is considered using a probabilistic Boolean network (PBN). In real-time pricing systems, electricity conservation is achieved by manipulating the electricity price at each time. A PBN is widely used as a model of complex systems, and is appropriate as a model of realtime pricing systems. Using the PBN-based model, real-time...

The recent developments in information technology (IT) have enabled firms to employ personalized pricing. Should all firms employ personalized pricing even though the adaptation costs of such pricing strategies are not high? This paper theoretically demonstrates a situation in which all firms do not always employ personalized pricing even though the fixed costs to do so is zero. The model is ba...

in spain, camping accommodation accounted for 6.32% of total tourism accommodation and 8.2% of overnight stays in 2007. there were 1,152 registered campsites which provided lodging for almost 6.4 million users. although these figures are higher than those of rural accommodation, few studies have analyzed the main attributes of this sector and their contribution to the development of spanish tou...

Financial models are largely used in option pricing. These physical models capture several salient features of asset price dynamics. The pricing performance can be significantly enhanced when they are combined with nonparametric learning approaches, that empirically learn and correct pricing errors through estimating state price distributions. In this paper, we propose a new semiparametric meth...

because of the need to develop specific measurement scales for different services industries, this study aimed to empirically develop a reliable and valid model specifically for measuring mobile telecommunication service quality. a multidimensional measurement model (ms-qual) has been proposed based on an extensive literature review and then, to assess the model validity, convergent and discrim...
