基于实物期权的旅游企业并购估值研究

旅游企业相比传统企业的独特性决定了其企业价值评估方法的特殊性,若将传统的现金流量折现模型与实物期权理论有效结合,将大大提高旅游企业价值评估的灵活性和准确性。本文针对传统企业价值评估方法在不确定因素下无法有效评估的缺陷,构建了现金流量折现模型和实物期权理论相结合的定价模型。结果表明,旅游企业中确实存在大量的实物期权,并且基于实物期权理论进行估值能够更加准确地评估旅游企业价值。     

互联网企业价值评估研究

近年来,互联网行业快速发展,互联网企业之间通过开展融资、资产并购重组、股权转让等经济业务,在竞争中谋求发展.随之而来的问题是确切地评估一家互联网企业的价值,这成为一个新的课题.本文首先在总结前人的基础上,对企业价值评估常用的传统方法,包括收益法、市场法以及成本法进行了分析;其次,对适用于互联网企业特征的DEVA方法、实物期权法进行分析,并指出互联网企业评估难点;最后,结合美团网分别采用传统法现金流贴现法和DEVA估值法进行价值评估,认为DEVA估值法更适用于互联网企业.     

高科技上市公司内在价值评估：基于连续型实物期权模型的实证研究

高科技企业高度不确定性的特征决定其本身具有潜在的期权价值,所以,传统的评估方法难以客观地评估出高科技公司内在价值.针对高科技公司高度不确定性的特征,引入Schwarz的连续型实物期权模型,在对模型进行离散化处理后,利用蒙特卡洛模拟对中国软件开发板块的高科技上市公司进行价值评估,并由此对整个软件开发板块的高科技上市公司价值评估进行的实证.研究发现,实物期权模型能较好地对高科技企业进行价值评估.

随着国家助推互联网的发展,越来越多的企业进入互联网领域,同时一些互联网企业开始做大做强,伴随着互联网企业的融资、并购重组、上市等问题必然会涉及企业价值评估。本文突破传统的评估三法,引入实物期权法对上市互联网企业进行股权价值评估,并对其进行实证分析,检验其股价的合理性,同时也为上市互联网企业的股权价值评估提供一个新的评估角度。     

模糊环境下商标权评估的实物期权定价模型

模糊环境下基于实物期权的商标权评估模型,是考虑了商标权具有扩张期权、收缩期权、放弃期权等期权特征,以及商誉潜在价值的不确定性等因素,将实物期权定价模型与模糊集理论相结合而提出的一种商标权价值评估方法。它比传统的DCF法能够更合理地评估商标权的价值。     

实物期权法在电子商务企业价值评估中的应用研究

2016年上半年中国电子商务交易规模达10.5万亿元,同比增长37.6%。电商的迅速发展使得电子商务企业的价值评估受到越来越多的关注。电子商务企业的发展具有较大的不确定性,其增长速度、盈利模式等与传统企业有较大的不同。因此,传统的企业价值评估方法对于电子商务企业价值评估来说适用性较差。本文针对电子商务企业的具体特点,分析电子商务企业中的实物期权,选择合适的实物期权模型,对电子商务企业的价值进行评估。     

并购中企业实物期权价值评估的研究

本文采用实物期权法,建立了企业并购中目标企业的价值评估模型,认为并购中目标企业的价值不仅包括企业自身的价值,还应包括由于并购的实物期权特征和协同效应产生的目标企业的附加价值。目标企业自身的价值由传统的折现现金流法计算并通过实物期权理论调整;并购附加价值由实物期权法,改进的折现现金流法和专家评分法进行计算和分配。     

基于实物期权模型的企业并购项目定价研究

为有效测度企业并购项目的价值,本文在整理相关并购项目价值评估研究文献的基础上,结合企业并购的基本理论及并购项目价值的实物期权特性,构建企业并购项目价值评估的实物期权模型,并利用构建的Black-Scholes模型对企业并购项目期权价值进行定量测算。结果显示,基于实物期权的企业并购项目定价模型弥补了现有模型对企业不确定性价值的低估,为企业客观评价并购项目的真实价值提供了新的思路和方法。     

企业并购中实物期权定价的再探索

实物期权法在企业价值评估中的应用已久,但在并购领域,实物期权法的应用却存在一定不足之处,在并购中使用实物期权法进行企业价值评估,由来的方法并未考虑并购前后企业风险的变化,其仅仅是使用并购前历史的波动率估计实物期权价格。针对这一不足,本文提出了将波动率与并购前后企业资产负债率联系在一起的模型改进方法,将企业并购前后的风险变化融入到实物期权定价模型中,以期得到更加准确的实物期权价值。

Bayesian Premium Rating with Latent Structure

We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.     

The development of the group accounts disclosure system in Japan

The Japanese disclosure system of consolidated statements was introduced in 1977 and extensively revised in 1997. The role of the bureaucracy has been significant in these developments and seems to be part of Japan's closed culture. However, other explanations could also be applied. In particular, although Japanese firms opposed such disclosures on the basis of preparation costs, the Japanese government had to modernize the disclosure system, including consolidation, in order to develop the securities market regardless of an individual company's interests.     

Moments of Compound Mixed Poisson Distributions

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.     

The designing of corporate accounting law in Japan after the Second World War

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.     

The deliberation around accounting techniques: accounting for depreciation and foreign exchange in an Indian jute company, 1870-1900

This paper examines the way two accounting techniques, namely depreciation and foreign exchange, were deliberated on, between 1870 and 1900, in an Indian jute company whose shareholders resided in the UK. The arena for these deliberations was the conflictual relationship between controlling and non-controlling shareholders as to how best to account for depreciation and foreign exchange especially when the particular accountings affected distributional issues such as the dividend decision. The purpose of this paper is to analyse and explain the processes by which a company's accounting practices emerge and develop as a contest between different interests. Accounting framed the parameters of the deliberations and provided the language of power and dissent. The paper uses a rich archive that includes narrative and accounting material.     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.     

Pricing Dynamic Insurance Risks Using the Principle of Equivalent Utility

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.
