Why do people purchase from food delivery apps? A consumer value perspective

Consumers are increasingly using food delivery apps (FDAs) to facilitate convenient and quick food delivery. Yet, the existing research offers a limited understanding of consumers’ behavioral responses to the visibility and values derived from FDAs. Our study utilized the theory of consumption values (TCV) to examine associations between FDA visibility, consumption values, and purchase intentions. The mediating role of consumption values and the moderating role of attitude was also studied. A qualitative study was conducted with 15 FDA consumers to derive context-specific consumption values. Responses from 355 FDA consumers from the United States of America (USA) were obtained through Prolific and analyzed using structural equation modeling. Visibility acted as an antecedent of all consumption values and significantly influenced purchase intentions. Attitude also positively and significantly influenced purchase intentions. Consumption values partially mediated the association between visibility and purchase intention, while attitude negatively moderated the relationship that purchase intention has with visibility and preference value. These findings have important implications for theory and practice.     

Consumption,welfare, and stochastic population dynamics when technology shocks are (Un)tied

The impact of uncertainty on consumption and welfare seems obvious; because of the precautionary saving motive, higher uncertainty reduces consumption, and subsequently, deteriorates welfare. Recent several studies, however, find that this intuitive narrative is not necessarily true. This paper provides the analytical underpinnings for this. In the absence of technological progress, I find that the larger demographic shocks always reduce consumption, but improve the welfare of households. Moreover, when demographic shocks are negatively tied to technology shocks, there emerges an inverted-U relationship between the size of two shocks and consumption, and a U-shaped relationship between the size of two shocks and household welfare. These results are all characterized analytically in the framework of the stochastic two-sector growth model featuring the correlated Brownian motion process. The findings suggest that demographic policies should not be implemented with no reference to the state of technology.     

中国消费率和投资率的合理性判断：1978-2005

无论从国际比较,还是从对中国资本生产率以及增量资产产出率的分析来看,中国消费率显著低于国际水平,而投资率显著高于国际水平,且偏低的消费率与偏高的投资率存在着明显的不协调。     

Home Equity,Household Savings and Consumption

The home-owning family’s equity is a piggybank that can be broken open by borrowing. Each borrowing increases liabilities and cash equally, initially leaving net wealth unchanged. When those funds are spent and cash balances fall, consumption increases even as net wealth can decline. In a dynamic optimization, the marginal propensity to consume from net wealth is not always positive and can be positively correlated with housing debt.

劳动力流动、征税方式转变与地区福利增进

研究目标：在劳动力流动程度的不同阶段研究税率结构变化与效率和公平之间的关系。研究方法：构建了征税方式转变与劳动力跨区域流动的两地区一般均衡模型进行理论模拟,采用面板门限模型进行实证检验。研究发现：随着劳动力流动程度的提高,在保持宏观税负不变下由增值税转为消费税的税率结构变化可以提升效率水平和改善公平状况。其中征税方式转变对于效率的正影响越来越大,对于公平的影响也由负转正,劳动力流动存在显著的门限效应。研究创新：结合劳动力流动影响因素进行消费税和增值税的税收扭曲效应差异机制的比较研究。研究价值：统筹协调税制结构改革与户籍制度改革,促进劳动力流动与税率结构优化,实现福利增进的双重红利。     

Rare disaster risk and the expected equity risk premium

Consistent with the predictions of rare disaster models, we find that a proxy for the time‐varying probability of rare disasters helps to explain fluctuations in expectations of the equity risk premium. Our proxy for disaster risk is a recently developed measure of global political instability, and the expected market risk premium is from Value Line analysts' expected stock returns. Consistent with long‐run risk models, uncertainty about expected GDP growth and expected consumption growth is also significantly positively related to the expected market risk premium. We obtain similar results when we use the earnings–price ratio and the dividend–price ratio as proxies for the expected market risk premium.     

消费结构升级与技术进步

文章将技术进步分解为技术效率与技术创新,并沿着成果转化、自主创新和技术模仿等路径,探讨了消费结构升级对技术进步的影响及条件。文章认为,消费结构升级引导着资源的配置方向;沿着不同的路径,消费结构升级带来了不同形式的技术进步。一方面,消费结构升级可促进科技成果转化,在生产前沿不变的条件下提高技术效率。当发明专利得到更好的保护时,生产者推动成果转化的积极性会提高,这时,可用的科技成果越多,消费结构升级越能推动技术效率提升。另一方面,消费结构升级还能推动企业突破现有的生产前沿,实现技术创新。由于小企业运营更灵活、竞争压力更大,在企业平均规模较小的市场结构中,消费结构升级更能推动技术创新;而政府主导的研发往往缺乏行业需求等信息,可能与消费者的实际需求脱节,因此,政府主导的研发投入越多,消费结构升级越难拉动技术创新。不仅如此,在开放条件下,企业还可以通过模仿去满足消费结构升级带来的新需求,进口越多,模仿的空间越大,这种模仿会提升技术效率,但可能会不利于技术创新。基于1999-2015年的省级面板数据,文章对上述假说进行了检验,结果表明上述论断成立。     

环境规制、技术创新与产业结构升级

本文利用我国30个省市1998～2013年的数据构建面板门槛模型,对环境规制、技术创新与产业结构升级之间的关系进行实证分析。研究结果表明：环境规制对产业结构升级的影响存在显著的环境规制程度和技术创新水平的双门槛效应,进一步分析发现产业结构升级是以技术创新为前提的,若无法有效的激励企业进行技术创新,而单纯依靠强化环境规制来实现产业结构升级是不可持续的。     

以扩大内销推动珠三角加工贸易企业转型升级方略

扩大内销可以对珠三角加工贸易企业转型升级起到提供巨大国内市场空间、促进“研发-生产-销售”完整产业链条的构建、转“候鸟”经济成为“榕树”经济等助力作用。但是受到自主品牌缺失、诸多无形市场障碍存在、国家进口设备税收政策负影响、传统内销管理模式制约严重等因素制约,转型之路并不平坦。应当通过扶植自主品牌、注重知识产权保护、完善国家进口设备税收政策、推动内销便利化等措施促进珠三角加工贸易企业扩大内销。     

农村社会保障支出对农村居民消费的影响的实证研究

从社会保障对居民消费影响机制的微观基础出发,运用协整分析并建立向量误差修正模型对我国农村社会保障支出的消费效应进行了实证研究.结果表明,我国农村社会保障支出没有对农村居民消费支出产生促进作用.因此,应加快农村社会保障制度的改革,促进农村居民消费,拉动内需.
