Access pricing: A comparison between full deregulation and two alternative instruments of access price regulation,cost-based and retail-minus

In this paper, two instruments of access price regulation, cost-based and retail-minus, are compared with the full deregulation hypothesis. For this purpose, a model that considers an upstream monopolist firm that sells a vital input to an independent firm and to a subsidiary firm in the downstream market is developed. The main conclusion of the paper is that retail-minus regulation avoids foreclosure and leads to better results than cost-based regulation in terms of investment level and consumer surplus. Moreover, retail-minus regulation allows a higher consumer surplus than deregulation of access price as long as the regulator carefully defines the retail-minus instrument.     

What they know vs. what they do: how acquirers leverage technology acquisitions

Existing research suggests that in acquisitions of small technology‐based firms by large established firms post‐merger integration both enables and hinders acquirers' efforts to leverage the technology of acquired firms. This apparent paradox can be resolved once we account for the qualitatively distinct ways in which acquirers leverage technology acquisitions. Integration helps acquirers use the acquired firm's existing knowledge as an input to their own innovation processes (leveraging what they know), but hinders their reliance on the acquired firm as an independent source of ongoing innovation (leveraging what they do). We also show that experienced acquirers are better able to mitigate the disruptive consequences of the loss of autonomy entailed by integration, though we find no evidence that they achieve greater coordination benefits from integration.

美国税权划分制度评析与借鉴

美国的联邦、州和地方三级政府各自拥有属于本级的税权,并在同级政府层面上表现为税收立法权、执法权和司法权三者之间的划分与制衡。本文通过分析美国税权划分的主要特点,对我国税权划分改革提出了若干建议:确定税权划分的法定主义原则、税收立法权划分的指导思想、赋予地方适度税权的具体设想、明确划分中央与地方税收执法权限、建立解决地区间税权争议的协调机制、通过一些制度设计完善税收司法权的行使。     

论个人所得税的二元课税模式

由于综合个人所得税制在理论基础和实际征管方面都存在着难以克服的困难,发端于北欧国家的对劳动所得适用累进税率而对资本所得适用比例税率的二元个人所得税制就成为一种较为现实而理想的模式,在国际上正得到日益广泛的支持。我国近年提出的综合与分类相结合的个人所得税制模式近似于二元所得税制,应当作为个人所得税改革的长远目标,但还需对具体制度安排进行恰当的设计。     

适当下放地方税立法权完善税收立法体制

当前中央和地方税收立法权划分中存在一些问题和矛盾。要化解这些矛盾、解决这些问题,需要在借鉴历史和国外经验的基础上,区别不同的地方税税种,分层次、有限度、可控制地下放部分税收立法权,完善税收立法体制,健全分税制财政管理体制以至整个财税体制。     

浅议城市房地产税中土地使用权的计税依据

城市房地产税的计税依据是企业账载的房屋原值,土地使用权是房屋价值的重要组成部分。由于土地和房屋的使用年限不同,并且存在道路、绿化等独立于房屋之外的土地,如何在时间和空间上界定城市房地产税中土地使用权的计税依据,本文结合税法及企业会计制度的现行规定,根据城市房地产税的立法精神,对此问题进行了阐述。     

房地产税收调控政策的效应分析与建议

本文梳理了2005年以来国家针对房地产投资规模过大和部分城市住房价格上涨过快状况而出台的多项税收调控措施,并通过理论和实证分析认为,房地产税收调控政策的重点应从目前对供给方征税转向对需求方征税,即在房地产保有环节征税。为此,应尽快建立起全面准确的房地产信息资料和监控系统,加快推进物业税(不动产税)的改革。
