The impact of tax reforms on unemployment in a SMOPEC

This paper analyzes revenue-neutral tax reforms for a small open economy which is constrained to a balanced current account and whose producers have market power on the world market. We consider origin-based and destination-based commodity taxes as well as taxes on income, the payroll, and on an imported factor of production. Our main findings are the following. First, the strength, and for some parameter constellations, even the sign of the employment effect of tax reforms varies with the degree of openness of the economy. Second, the indeterminacy of the sign of the employment effect crucially hinges on the presence of an internationally mobile factor. The central mechanism underlying our results are adjustments of the real exchange rate which have repercussions on wage and price setting and therefore on employment.     

论循环经济发展中相关税制的绿化问题

循环经济是一种关注资源减量、实现资源循环及再利用的生态经济.当前,我国经济增长要求与有限的资源和环境支持能力都要求大力发展循环经济,在此过程中政府的税收政策和优惠支持倍显重要.本文以此为基点,按照循环经济的内在要求,分析了国内循环经济发展中税制上存在的问题,并在借鉴国外先进经验基础上,提出了绿化现有相关税制的思路和对策.     

Capital income taxation of Swedish households, 1862–2010

This study describes the evolution of capital income taxation, including corporate, dividend, interest, capital gains and wealth taxation, in Sweden between 1862 and 2010. To illustrate the evolution, we present annual time-series data on the marginal effective tax rates on capital income (METR) for a marginal investment financed with new share issues, retained earnings or debt. These data are unique in their consistency, thoroughness and time span. We identify four tax regimes separated by shifts in economic policy. The first regime stretches from 1862 until the Second World War. The METR is low, stable and does not exceed 5% until the First World War, when the METR begins to drift upwards and varies depending on the source of finance. The outbreak of the Second World War establishes the second regime, when the magnitude and variation of the METR sharply increase. The METR peaks during the third regime in the 1970s and 1980s and often exceeds 100%. The 1990–1991 tax reform represents the beginning of the fourth regime, which is characterised by lower and smaller variations in the METR. The METR varies between 15% and 40% at the end of this period.     

基于ECM的我国税收弹性实证分析

运用时间数列和计量分析方法,利用1978--2006年我国税收收入和GDP数据,针对1978—1994年和1995--2006年两个阶段分别建立误差修正模型,对我国税收的长期弹性和短期弹性进行分析。研究结果发现：1978—1994年我国税收的长期弹性小于其短期弹性;自1995年以来,我国税收弹性发生了显著变化,税收的长期弹性大于其短期弹性。     

产权性质、会计-税收差异与审计收费——来自中国A股上市公司的经验证据

］通过考察注册会计师对审计服务定价时是否考虑会计利润与应纳税所得额之间差异（以下简称“会计-税收差异”）所包含的财务信息,研究发现会计-税收差异与审计收费显著正相关。进一步区分产权性质后发现,对于国有控股上市公司来说,会计-税收差异与审计收费正相关,但这种相关性并不显著;而对于民营上市公司来说,会计-税收差异与审计收费显著正相关。研究结果表明,会计-税收差异会影响注册会计师对审计风险的判断,进而通过增加审计程序来降低审计风险,提高审计收费。且在审计定价时,对于不同产权性质的公司,注册会计师差别对待了会计-税收差异中所包含的信息。     

营业税改征增值税试点方案对港口企业的影响研究

2012年国家在上海等11个省市开展了交通运输业和部分现代服务业营业税改征增值税的试点工作,这一改革给港口企业一般纳税人的税负带来了影响,通过两种税负的比较分析,其因素包括税率偏高、可抵扣成本低等多个方面,应当采取扩大改革范围、给予企业过渡期补贴扶持、择机统一下调税率等措施。     

Consumption externalities,market imperfections and optimal taxation

In a dynamic model with a keeping‐up‐with‐the Joneses preference and market imperfections, we attempt to investigate under what circumstances and for what reason the optimal tax should be state‐varying. We extend the Ljungqvist and Uhlig (2000) proposition to include preferences that exhibit non‐homotheticity. We show that a keeping‐up‐with‐the‐Joneses preference (a non‐intertemporally‐dependent preference) can lead the social planner to commit to a state‐contingent tax on labor income. Moreover, the optimal labor income tax can be either procyclical or countercyclical with respect to economic fluctuations, this crucially depending on whether the level of contemporaneous consumption increases or decreases the wedge between the intertemporal substitution elasticity of households and of the social planner.     

税收分权指标构建及经济增长的影响效应

研究税收分权对中国经济增长的影响,首先在于税收分权指标的选择。通过构建一个"地方税收收入自给率"指标来衡量税收分权的程度,并对中国2006~2012年税收分权实践与经济增长的关系进行实证分析,研究发现:近年来,中国税收分权程度不断下降,中央税收集权趋势明显;地方税收收入自主率与经济增长之间正相关。     

我国增值税扩围改革研究文献述评

分税制改革后,我国形成了增值税和营业税并存的局面,分别在中央和地方财政收入中占据主要地位,这对市场经济的运行造成了一定的扭曲,不利于经济结构的转型,因此增值税扩围改革势在必行。增值税扩围意味着营业税最终被取消,建立这样一个新体制对既有利益分配格局的冲击是显而易见的,在这一改革中如何兼顾各方面的利益将是增值税扩围改革能否取得成功的关键。本文主要对近年来国内学者关于增值税扩围及其相关问题的研究成果进行梳理,以期能为改革实践和有关研究提供参考。     

关于纳税信用等级评定的信息化途径研究

加强纳税人信用等级评定工作,是税收征管工作中非常重要的一环,随着信息技术的飞速发展,我国税收征管信息化取得了长足进步。然而,当前我国纳税信用等级评定中还存在着评定手段落后、评定结果客观性较差、纳税人积极性不高等问题。依托先进的信息技术,从完善评定指标体系、扩大信息采集渠道、优化评定手段等多个方面,可以进一步加强和改进纳税信用等级评定工作。
