Vertical and financial ownership: Competition policy and the evolution of the UK pub market

Abstract

Traditionally the UK brewing industry was vertically integrated with brewers owning and controlling pubs. This came to an abrupt end in the forced divestment of a large proportion of the major brewers' pub estates in the 1989 ‘Beer Orders’. The divested pubs spawned the independent pub companies. This study of regulatory policy and financial services interest in the UK brewing industry poses the question of whether the original industrial structure was preferable to what has emerged subsequently. The contribution of the article is in highlighting the risks and rewards of regulatory intervention in deeply-embedded organisation and the sustainability of alternative business models that emerge.     

论国际税收竞争与竞争性的中国税制

本文从国际税收竞争基本概念入手,明确国际税收竞争与有害税收竞争的区别与联系.运用实证分析的方法,说明世界各国税收竞争的发展与现状,指出税收竞争是经济全球化发展的历史必然.通过比较,认为我国税制具有一定的竞争力,但仍存在一些不足.为了完善税制,本文提出建立竞争性中国现代税制的初步设想.     

银行业集中、竞争与稳定的研究述评

传统的观点认为银行业的集中有助于系统的稳定,这导致众多国家采取各种监管政策来限制竞争。但是,对于银行系统的竞争与集中对稳定性的影响,理论分析与实证研究均给出模糊的结论。本文分析各种度量竞争与稳定的方法,并在对1990~2010年间有关竞争、集中与稳定性的文献进行综述的基础上,提出了相应的政策建议,以期为我国银行业的监管提供启示和借鉴。     

出口机会与进口竞争对工业机器人企业的叠加影响：基于出口持续时间的视角

工业机器人企业是中国推动制造业数字化革命、抢占国际分工制高点战略的主力军,然而其出口持续时间平均不足1年,需引起高度关注。本文基于2000-2015年中国海关数据库和工业企业数据库的匹配数据,运用Cox风险模型分析了出口机会增大和进口竞争加剧对工业机器人企业出口持续时间的影响和作用机制。结果表明,出口机会增大更有利于延长企业出口持续时间,进口竞争加剧则提高了企业的退出率,这一结论在产品多样化程度低、产品核心度低、行业竞争小和市场集中度低的企业中尤为明显;出口机会与进口竞争,主要是通过企业生产率和技术创新的中介作用影响企业的出口持续时间;面对双重叠加影响,工业机器人企业应充分利用产品间的技术关联效应提高出口持续性。     

Applicability of the M5 to Forecasting at Walmart

The M5 Forecasting Competition, the fifth in the series of forecasting competitions organized by Professor Spyros Makridakis and the Makridakis Open Forecasting Center at the University of Nicosia, was an extremely successful event. This competition focused on both the accuracy and uncertainty of forecasts and leveraged actual historical sales data provided by Walmart. This has led to the M5 being a unique competition that closely parallels the difficulties and challenges associated with industrial applications of forecasting. Like its precursor the M4, many interesting ideas came from the results of the M5 competition which will continue to push forecasting in new directions.In this article we discuss four topics around the practitioners view of the application of the competition and its results to the actual problems we face. First, we examine the data provided and how it relates to common difficulties practitioners must overcome. Secondly, we review the relevance of the accuracy and uncertainty metrics associated with the competition. Third, we discuss the leading solutions and their implications to forecasting at a company like Walmart. We then close with thoughts about a future M6 competition and further enhancements that can be explored.     

企业环境信息披露影响因素实证分析:2010~2011年A股重污染行业上市公司观察

以2010～2011年A股重污染行业上市公司作为研究对象,从产品市场竞争、公司治理角度考察了企业环境信息披露的影响因素。结果显示：公司治理结构的合理安排能够对提升企业环境信息披露质量产生一定的积极作用,但是产品市场竞争与公司治理机制之间的关系尚不明确。本文的研究结论意味着,在我国当前的制度背景下,要提高企业环境信息披露水平,保护利益相关者利益,有必要继续完善上市公司治理结构;同时,本研究也说明产品市场竞争并不能解释重污染行业企业环境信息披露的动机。     

基于Lotka-Volterra模型的中国股票市场非线性特征—— 一个生态学的视角

股票市场是一个非线性的复杂动力系统,将生态学的多种群Lotka-Volterra竞争模型进行改进后引入到股票市场,通过系统仿真,模拟中国股市运行,得出了类似于股票市场运行的非线性特征,为研究股市复杂性提供了新思路。     

空间双寡头竞争下的创新扩散——基于博弈论的模型

关于创新空间扩散的研究一直没有关注空间竞争对于创新采纳的影响.本文在双人博弈的框架下构建了一个空间双寡头竞争模型,假定厂商已经拥有关于创新的信息,单纯地考察空间竞争对于创新采纳的影响.结果表明,即使同质的厂商同时获得了创新的信息,在竞争的作用下,创新的采纳很少会同时进行.先采纳者具有先发优势,且随着运费率的下降,先发优势愈发得以强化.本文还分析了空间竞争和技术扩散反梯度现象间的关系,结论是空间竞争至少是反梯度现象产生的一个原因.     

China's Financial Development

At the China Development Forum in Beijing, March 2002, I was asked to be discussant to Governor Dai Xianlong, but his paper, as in most cases, was not made available beforehand, so my own comments had to be made independently. Following that event, I can now remark on the Forum as well as reproducing my discussant paper. In this latter, I emphasize the importance of developing professional skills, greater competition and the application, through regulation, of appropriate incentives for the continued improvement of China's financial system.     

Technological forecasting at the Korean stock market: A dynamic competition analysis using Lotka–Volterra model

The purpose of this paper is to attempt to analyze the dynamic relationship between the Korean Stock Exchange (KSE) and Korean Securities Dealers Automated Quotation (KOSDAQ), two competing markets at the Korean stock market, in the viewpoint of technological forecasting of competition. The Lotka–Volterra system of equations, one well-known competitive diffusion models, is adopted to represent the competitive situations of the Korean stock market and it is estimated using daily empirical index data of KSE and KOSDAQ during 1997–2001. The results show that there existed a predator–prey relationships between two markets in which KSE acted as a prey for the time being after the emergence of KOSDAQ. This interaction was altered to symbiotic relationship and finally to pure competition relationship. We also perform an equilibrium analysis of the estimated Lotka–Volterra equations. As a result, we find that there is an equilibrium point in a dynamic sense. However, the equilibrium point could be unstable in the latest pure competition relationship.
