Public Disclosure of Forward Contracts and Revelation of Proprietary Information

Financial executives of firms engaged in forward contracting have raised concerns that mandated disclosure of those contracts would reveal proprietary information to rival firms. This paper considers the basis for those concerns in the framework of a duopoly in which one privately informed producer enters the forward market prior to production. In choosing its forward position, the firm considers the effects of that position on the forward price and second stage product market competition with its rival. Two regimes are considered: mandated disclosure and no disclosure. Under the former, the contracting firm faces a tension between exploiting its information advantage in the forward market and attempting to influence the production decision of its rival. On average, in equilibrium, the contracting firm gains a first-mover advantage, but at the cost of revealing its private information to its rival and extracting less expected gains from uninformed forward market participants. In contrast, with no disclosure, the contracting firm cannot influence rival firm beliefs, but extracts more expected gains from its private information in both the forward and product markets. On balance, the contracting firm prefers no disclosure. Moreover, parameterizations exist such that the rival also prefers that regime. These findings explain the opposition of respondents to draft proposals of Statement of Financial Standards No. 133.     

交叉外汇远期合约的定价及应用

目前,我国市场上推出的金融衍生工具很少,没有可用来对冲系统风险的金融工具,因此,2001年后资本市场的衰落导致券商和基金发生大面积亏损.设想,如果政策允许,可以使用一种以外国股票或股指作为标的而以本币进行计价的金融衍生工具(交叉外汇远期合约、期货和期权)对冲系统风险,即利用外国股市与我国股市的相关性对投资组合进行套期保值.这里我们将介绍如何使用该方法对交叉外汇金融衍生工具的一种交叉外汇远期合约进行定价,推导套期保值的原理并介绍用其对冲系统风险的操作方法.     

货币政策前瞻性指引有助于稳定经济——基于预期视角的数量分析

预期在广义虚拟经济中处于重要地位,是经济活动的主要驱动力之一,而货币政策前瞻性指引即是通过引导公众形成对货币政策的预期以达到维护经济稳定的目的。本文在新凯恩斯动态随机一般均衡模型框架下,运用贝叶斯方法,从预期的角度研究我国货币政策前瞻性指引需针对的主要经济目标及预期冲击影响宏观经济的数量特征。研究发现,货币政策预期冲击的短期效应更强;货币政策预期冲击对通胀的影响显著,其次是对就业的影响,对产出、消费、投资和资本的影响相对较小;通胀与产出、消费、投资和资本同方向波动。实行货币政策前瞻性应主要针对通胀和就业目标,引导公众形成可预期的货币政策环境有助于维护宏观经济的稳定。     

Forecasting technology costs via the experience curve — Myth or magic?

To further understand the effectiveness of experience curves to forecast technology costs, a statistical analysis using historical data is carried out. Three hypotheses are tested using available datasets that together shed light on the historical ability of experience curves to forecast technology costs. The results indicate that the Single Factor Experience Curve is a useful forecasting model when errors are viewed in their log format. Practitioners should note that due to the convexity of the log curve a mean overestimation of potential cost reductions can arise as values are converted into monetary units. Time is also tested as an explanatory variable, however forecasts made with endogenous learning based on cumulative capacity as used in traditional experience curves are shown to be vastly superior. Furthermore the effectiveness of increasing weights for more recent data is tested using Weighted Least Squares with exponentially increasing weights. This results in forecasts that are less biased, though have increased spread when compared to Ordinary Least Squares.     

A UNIVERSAL OPTIMAL CONSUMPTION RATE FOR AN INSIDER

We consider a cash flow   X ^{( c )} ( t )  modeled by the stochastic equation where B (·) and     are a Brownian motion and a Poissonian random measure, respectively, and   c ( t ) ≥ 0  is the consumption/dividend rate. No assumptions are made on adaptedness of the coefficients  μ, σ, θ  , and c , and the (possibly anticipating) integrals are interpreted in the forward integral sense. We solve the problem to find the consumption rate c (·), which maximizes the expected discounted utility given by Here  δ( t ) ≥ 0  is a given measurable stochastic process representing a discounting exponent and τ is a random time with values in (0, ∞), representing a terminal/default time, while  γ≥ 0  is a known constant.     

Jump-Diffusion Processes: Volatility Smile Fitting and Numerical Methods for Option Pricing

This paper discusses extensions of the implied diffusion approach of Dupire (1994) to asset processes with Poisson jumps. We show that this extension yields important model improvements, particularly in the dynamics of the implied volatility surface. The paper derives a forward PIDE (PartialIntegro-Differential Equation) and demonstrates how this equationcan be used to fit the model to European option prices. For numerical pricing of general contingent claims, we develop an ADI finite difference method that is shown to be unconditionally stable and, if combined with Fast Fourier Transform methods, computationally efficient. The paper contains several detailed examples fromthe S&P500 market. This revised version was published online in November 2006 with corrections to the Cover Date.     

Currency Crisis in Korea – When and Why It Happened

Two possible causes of the Korean financial crisis are examined: (1)deterioration of the macroeconomic indicators andinconsistent policies and (2) sudden shifts in the market expectation andconfidence. Although the truthseems to lie between these causes, we conclude that the Korean currency crisisresulted from aserious mismanagement of foreign exchange rates and foreign currency reservesas well as theaccumulation of short-term foreign debts. Although it is generally believedthat the exchange rate ofthe won started depreciating drastically on 8 November 1997, depreciationstarted three monthsearlier when the international market conditions put the pressure on the won.

Central Region:The Next Destination?

A new set of policies for processing trade were jointly imple mented by China's Ministry of Commerce and General Customs Office last year,with the goal of promoting trade balance,relieving the sharp contrast in China's huge trade surplus,as well as pushing forward with the improvement and transformation of the industry.
