This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings. 相似文献

Some implications of e-Commerce financial services firms are becoming clear. The web drives transparency, and increases the information endowment of all market participants. It is harder to manipulate customers' behavior, or to overcharge them. Transparency drives differential pricing. Not all customers can or should be charged the same prices. Transparency reduces the viability of cross-subsidies between customers can or between products. The differential pricing enabled by the web transforms distribution channels, and enables direct distribution and alternative forms of distribution. Some intermediateraries may be bypassed altogether, while others may rapidly lose their best, most profitable, and previously most loyal customers. 相似文献

This paper explores the implications of informational asymmetries between domestic and foreign investors for optimal capital tax rates and welfare. It adopts a model in which asymmetric information implies a home bias in equity. The paper finds that asymmetric information may raise capital tax rates by reducing the marginal cost of taxation. Furthermore, it shows that investors may gain from informational asymmetries. Although asymmetric information increases the uncertainty as perceived by investors, it may also increase tax rates and allow for a higher consumption of public goods. This reflects that asymmetric information may reduce the distortionary effects of competition among governments. 相似文献

Frictions, Heterogeneity and Optimality in Mortgage Modeling 总被引:1,自引:0,他引:1
The purpose of this article is to provide a unified framework for incorporating frictions into a theoretical options-pricing model (OPM) for mortgages. This article presents formulation for a frictions-adjustable mortgage model that integrates borrower heterogeneity while simultaneously preserving prepayment and default financial decisions. Our model demonstrates the flexibility of the OPM by simulating separate and concurrent effects of three categories of frictions on the mortgage and mortgage components. Researchers can use our example formulation to determine the effects of specific borrower characteristics on mortgage values without destroying the options theoretic framework. 相似文献

One method for valuing path-dependent options is the augmented state space approach described in Hull and White (1993) and
Barraquand and Pudet (1996), among others. In certain cases, interpolation is required because the number of possible values
of the additional state variable grows exponentially. We provide a detailed analysis of the convergence of these algorithms.
We show that it is possible for the algorithm to be non-convergent, or to converge to an incorrect answer, if the interpolation
scheme is selected in appropriately. We concentrate on Asian options, due to their popularity and because of some errors in
the previous literature.

This paper develops a pricing model and empirically tests the pricing efficiency of options on the U.S. Dollar Index (USDX) futures contract. Empirical tests of the model indicate that the market consistently overprices these options relative to the derived model. This overpricing is more pronounced for out‐of‐the‐money options than for in‐the‐money options and more pronounced for put options than for call options. To validate the above results, delta neutral portfolios are created for one‐ and two‐day holding periods and consistently generate positive arbitrage profits, indicating that on average the market overprices the options on the USDX futures contracts. 相似文献

The direct valuation procedure of performing discounted expectation to obtain the prices of multi-state lookback options may
lead to insurmountable complexity and numerical difficulties. The computation may require numerical differentiation of the
joint distribution function of the extremum values, then followed by numerical integration over a semi-infinite domain. In
this paper, we illustrate the use of an alternative approach that significantly simplifies the calculations of multi-state
lookback option prices. The financial intuition behind the new approach involves the choice of a sub-replicating portfolio
and the adoption of the corresponding replenishing strategy to achieve the subsequent full replication of the derivative.
The replenishing premium is obtained by performing the integration of an appropriate distribution function over the range
of asset price within which under replication occurs. The sub-replication and replenishment procedures may be utilized as
hedging strategies for the lookback options. The pricing and hedging properties of multi-state lookback options are also discussed.
