碳排放约束视角下产业智能化对区域经济差距的影响研究

本文利用2003~2019年中国省级面板数据,从碳排放约束视角出发,实证考察了产业智能化对区域经济差距影响的差异性和产业智能化影响区域经济差距的机制。研究表明,产业智能化对缩小全国、东、中和西部地区省域间经济差距具有显著的正向效应;进一步考虑碳排放约束,发现碳排放约束正向调节了产业智能化对区域经济差距的正向效应,西部地区由于自身产业结构和区位因素,抑制了产业智能化对区域经济差距的正向效应;最后,对产业结构升级的两个子维度在产业智能化和区域经济差距间的中介效应检验,发现产业结构升级的中介效应存在,且主要是通过产业结构高级化实现,产业结构合理化发挥的作用较小。     

资本约束背景下定向降准对企业信贷的定向引导效果

2017年,央行将普惠金融和定向降准相结合,定向降准能否精准引流决定着政策的成败。基于上市公司2011年至2019年的面板数据,采用双重差分法检验定向降准是否能够实现其政策目标,定向向三农和小微企业引导信贷资源,并用三重差分法引入资本约束这一调节变量,检验资本约束的增强是否对定向降准的实施效果有影响。结果表明:定向降准能够达到政策目标,增加三农和小微企业可获得的信贷资源,此外资本约束对定向降准的实施效果无显著影响。     

Optimal mixed taxation,credit constraints,and the timing of income tax reporting

We study optimal income and commodity tax policy with credit‐constrained low‐income households. Workers receive an even flow of income during the tax year, but report their incomes and make tax payments (receive transfers) at the end of the year. They spend their disposable income on multiple commodities over the year. We show that differentiated subsidies on commodities can be optimal even if the Atkinson–Stiglitz Theorem conditions apply. When the optimal policy leaves low‐income households with binding credit constraints, it may be optimal to subsidize differentially the good that they consume in higher proportion. Uniform subsidies would also relax the credit constraint, but would be more costly to the government since they would equally benefit unconstrained households. Numerical examples suggest that commodity tax differentiation increases with basic needs and with the interest rate at which government borrows.     

What do fiscal stimulus packages mean for household debt?

We study the links between fiscal stimulus packages during times of crisis and households' liabilities. We do so by using household-level data on income and liabilities from the Consumer Expenditure Survey, and estimating an empirical model along those in the literature on the consumption effects of these packages. We find that receiving a check from the government tends to translate into a reduction in outstanding liabilities for American households. This effect is robust to controlling for income levels and household size. The effects are driven by households whose income is below the median and by those who remain employed during the crisis.     

自适应约束下的双边全变差正则化超分辨率重建

在经典的双边全变差(BTV)超分辨率重建中,加权系数和正则化参数的恒定性导致重建结果边缘保持能力受限。为此,提出了一种自适应约束的BTV正则化先验模型。算法首先定义了图像的局部邻域残差均值以区分当前像素属于平坦区域还是边缘区域;然后针对加权系数的不变性导致边缘削弱的问题,利用边缘方向和垂直边缘方向扩散性的不同,设计自适应权重矩阵;最后根据代价函数的极值问题推导出迭代公式,从而进行图像的超分辨率重建,重建过程中采用自适应的方法确定正则化参数,以便求得代价函数的全局最优解,提高了算法的鲁棒性。实验结果表明：与双三次线性插值法和经典BTV算法相比,该算法取得了更好的视觉效果和更高的峰值信噪比,更多地保留了图像的边缘细节信息。     

REDISTRIBUTIVE POLITICS AND GOVERNMENT DEBT IN A BORROWING‐CONSTRAINED ECONOMY

We develop a two‐period, three‐class of income model where low‐income agents are borrowing constrained because of capital market imperfections, and where redistributive expenditure is financed by tax and government debt. When the degree of capital market imperfection is high, there is an ends‐against‐the‐middle equilibrium where the constrained low‐income and the unconstrained high‐income agents favour low levels of government debt and redistributive expenditure; these agents form a coalition against the middle. In this equilibrium, the levels of government debt and expenditure might be below the efficient levels, and the spread of income distribution results in a lower debt‐to‐GDP ratio.     

Saving up or settling down: Home ownership over the life cycle

In a Bewley model with endogenous price volatility, home ownership and mobility across locations and jobs, we assess the contribution of financial constraints, housing illiquidities and house price risk to home ownership over the life cycle. The model can explain the rise in home ownership and fall in mobility over the life cycle. While some households rent due to borrowing constraints in the mortgage market, factors that affect propensities to save and move, such as risky house values and transactions costs, are equally important determinants of the ownership rate.     

Constraints to cruising across cultures and time

Cruise tourism is permeating the global arena. With companies developing new ships/itineraries for the U.S. and China markets, understanding constraints to cruising for different cultures carries significant value for cruise tourism development. This study adopted longitudinal and cross-cultural approaches to validate constraint measures. Data were collected in the U.S. in 2008 and 2017 and in China in 2017, using the same set of constraint measures across different times and cultures. This multi-dimensional triangulation approach was deemed important for testing the robustness of a measurement scale and is believed to be the first of its type. Findings validate the cruising constraint instrument across time and cultures and provide theoretical and practical implications.     

Resilience and well-being production among vulnerable consumers facing systematic constraints

This paper explores how vulnerable consumers within systematic constraints of economic inequality, institutional barriers, and social segregation in an urban environment cope with their vulnerabilities to achieve their well-being. Taking China's internal migrant workers as a research context, our study examines their vulnerable experiences and reveals the impact of systematic constraints on migrant workers' self-perception, interpretation, and actions. It discovers a staged process through which migrant workers acquire resilience to optimize life satisfaction by fulfilling a sense of control over their migration life. Through a situated approach to capture the contextual impact of systematic constraints on vulnerability experiences and the construction of resilient pathways to achieve well-being, this paper puts forward critical welfare issues such as inclusive marketplace, social capital, and community empowerment which are important to migrants' social integration and capability building. This calls for more coordinated efforts to promote effective resilience building and sustained well-being among resource-constrained consumers.     

Credit card cash‐out as informal financing: Evidence from China

Using a proprietary account‐level database from a commercial bank in China, we document that credit card holders can ease their credit constraints through the practice of cash‐out based on bogus transactions using credit cards. We find that such behaviour might be beneficial to both cardholders and banks. First, we find that a 1% increase in the cumulative number of credit card cash‐out transactions lowers the probability of default by 9.59%. Second, for private businesses, a 1% increase in the number of abnormal cash‐out transactions lowers overdue risk by 13.45%. Third, by lowering the overdue risk, the card‐issuing bank earns a larger profit. Our results are consistent with the notion that unconventional credit card cash‐out can mitigate the extent of capital misallocation in emerging markets.
