Endogenous cyclical corporate tax burden in China: The role of tax quotas and growth targets

Using data from China Annual Survey of Industrial Firms and addressing potential endogeneity problem, we find that corporate tax burden in China is procyclical during recessions and countercyclical during booms. The cyclicality is stronger for enterprises whose corporate income taxes are levied by Local Tax Bureau (LTB). Procyclicality of corporate tax burden during recessions is larger for enterprises located in county, non-state-owned enterprises (non-SOEs), non-high-tech enterprises and large-medium enterprises. Furthermore, tax quotas and growth targets of local governments enhance procyclicality during recessions and the countercyclicality of corporate tax burden during booms. Tax collection and government spending are important channels through which tax quotas and growth targets affect the cyclicality of corporate tax burden, respectively. This paper provides important policy implications for China during economic recessions.     

Low Mortgage Rates and Securitization: A Distinct Perspective on the US Housing Boom*

In this paper, we analyse the impacts of low interest rates and lax underwriting standards on the US housing boom around the beginning of the new millennium. We suggest a time-varying mean of the log price-to-rent ratio (PtR) to capture the persistent changes in housing prices. We show that the increasing latent trend in the PtR was significantly affected by the increased securitization of residential mortgage loans and decreasing interest rates, with the former effect being about three times larger than the latter. In the absence of securitization, negative interest rates would have been needed to reproduce an equally large housing boom since 2003.     

基于“全局道段优化模型”的末端配送作业模式

指出末端配送普遍采用固定道段的作业组织模式,道段组划依赖管理者的经验,难以适应邮件量、邮件分布及在岗投递员的变化。提出了基于柔性理念的“全局道段优化模型”,以该模型为核心开发了“智能揽投管控平台”,致力于提高揽投网点生产效率,降低成本,验证结果表明该模型可以减少行驶里程和工作时长。     

中国饲料企业原料价格风险规避策略研究

在贸易摩擦加剧和新冠疫情的多重冲击下,中外主要饲料原料品种价格波动剧烈,然而国内饲料企业普遍抗风险能力差,对于套保、套利策略的选择和使用尚缺乏灵活性.以2015年1月5日至2020年1月23日的豆粕、菜粕、玉米、大豆期现货价格数据为样本区间,应用误差修正模型估计最优套期保值比率及其有效性,并对4个原料进行跨品种套利的可行性进行实证分析.研究结论表明:最优套期保值策略能够有效规避风险且操作性强,跨品种套利策略可行但专业性较强.在此基础上,针对不同类型的饲料企业提出原料价格风险规避的对策和建议.

Authenticity and nostalgia – subjective well-being of Chinese rural-urban migrants

ABSTRACT

This study investigates the subjective well-being of Chinese rural-urban migrants by examining the effects of nostalgia and perceived authenticity in the context of rural tourism. Founded on the concepts of tourist motivation and nostalgia and drawn on selected Chinese philosophical values, this study identifies the unique Chinese philosophical value of ‘old home’ as the key factor of motivation for migrants returning to rural destinations. Rural-urban migrants deem rural regions, as well as, mentalities, cultures, and environments in general, as their cultural and spiritual hometowns. The study also reveals that migrants pursue authentic rural destinations, which would have an emotional and memorable appeal, because it stimulates their nostalgic feelings. The study proposes the necessity of investigating Chinese issues through the lens of Chinese philosophical values and invokes an age-old value to understand their perception process of authenticity: ‘one can't have fish and bear at the same time.’ Returning to rural destinations improves these tourists’ subjective well-being because they achieve an important lifetime goal based on their traditional Chinese philosophical value of ‘searching for ancestral roots.’ The study suggests that preserving rural authenticity can improve the social and cultural welfare of hosting communities and the subjective well-being of tourists.     

Optimal Dynamic Taxation with Distinctive Forms of Social Status Attainment

We examine the role of both consumption‐ and wealth‐induced social comparisons in setting dynamic optimal income taxation. Under complete information, state‐invariant labor income taxes are used to remedy the externality caused by consumption‐induced social comparisons, while state‐contingent capital income taxes are used to remedy the externalities caused by both consumption‐ and wealth‐induced social comparisons. Under incomplete information, distinct types of agents are subject to an identical marginal capital income tax, which removes social comparisons. To solve the information problem, low‐productivity agents could be subject to a lower marginal labor tax than high‐productivity agents, which contradicts the traditional result in the Mirrlees–Stiglitz models.     

Impact of trade cost on China-EU agri-food trade

In this research, we investigate trade costs in relation to China-EU trade in agri-food products during 2001–2015. Major components of trade cost include transportation costs, border-related policy barriers such as tariffs, and local distribution costs. Our results indicate that trade costs between China and EU involving agri-food products, although falling, remain abnormally high. Consequently, we find that trade cost reductions contribute to over half of the overall China-EU trade growth. Our decomposition technique demonstrates that economic growth and trade cost reductions are the key drivers of China-EU trade expansion. Implementation of the Belt and Road Initiative (BRI) would reduce high trade costs to increase EU-China bilateral agricultural trade significantly. This is not fully captured in the gravity models where a static distance is usually used as a proxy to trade cost. The BRI will not reduce the distance, but it will cut transportation and other components of trade cost for China-EU trade.
