马扎尔·瓦西姆 (Mazhar Waseem) 是曼彻斯特大学的经济学教授。在Quarterly Journal of Economics,Journal of Political Economy,Journal of Public Economics,Review of Economics and Statistics等重要学术刊物发表多篇。他的研究主要聚焦于新兴经济体的公共财政问题,特别是经济主体对税收和转移支付政策的行为反应。该研究的主要目的是理解在给定这些行为反应以及新兴经济体的执法环境下,如何改进当地的税收政策设计。他拥有伦敦政治经济学院(LSE)的经济学博士学位。他是财政研究所(Institute of Fiscal Studies)的研究员(Research Associate)、经济政策研究中心(CEPR)的研究会员(Research Affiliate),以及CESifo研究网络的研究员(Research Network Fellow)。在开始攻读博士学位之前,他曾在巴基斯坦税务局工作十余年。
内容提要
Size-based regulations and taxation are ubiquitous. We examine the impact of size-based taxation on firm growth by exploiting a large and permanent tax reform from Pakistan, where the VAT threshold was raised from PKR 5 million to PKR 10 million. Using a difference-in-differences framework and rich administrative data, we estimate the causal effects of this reform on firms whose growth was previously constrained by the size threshold. Our findings reveal substantial growth effects: treated firms saw their revenue increase by 32 log-points, costs by 19 log-points, and gross profits by 13 log-points. These effects are driven by real economic activity, as third-party reported outcomes, such as wages and imported inputs, also grew by similar margins. Treated firms paid higher taxes across various measures, highlighting their strong willingness to pay to get rid of the size-based taxation. The results emphasize the importance of carefully designing size-based policies, as they can lock firms into significantly slower growth trajectories.
基于企业规模的监管和税收政策无处不在。我们利用巴基斯坦一项重大且永久性的税收改革(增值税起征点从500万巴基斯坦卢比提高至1000万巴基斯坦卢比),考察了基于规模的税收对企业增长的影响。通过采用双重差分(Difference-in-Differences)框架并结合丰富的行政数据,我们评估了此项改革对那些此前因规模门槛而增长受限的企业所产生的因果效应。我们的研究结果揭示了显著的促进增长效应:受改革影响的企业,其营业收入增加了32个对数百分点(log-points),成本增加了19个对数百分点,毛利润增加了13个对数百分点。这些效应源于实际经济活动,因为由第三方报告的结果(如工资和进口投入品)也以相近的幅度增长。受改革影响的企业在各种税收指标上都缴纳了更多的税款,突显了它们为摆脱基于规模的税收而表现出的强烈纳税意愿。研究结果强调了精心设计基于规模的政策的重要性,因为此类政策可能将企业锁定在显著放缓的增长轨道上。
