A SWOT analysis of China's air cargo sector in the context of COVID-19 pandemic

This paper discusses the situation of China's air cargo sector facing the COVID-19 pandemic. Based on the expectation that it can go out of recession more easily than China's air passenger sector, this paper analyzes four aspects that are favorable and unfavorable for its further development: (1) strengths (China's sustainable economic basis and proliferating cargo suppliers), (2) weaknesses (insufficient cargo capacity and less business internationalization), (3) opportunities (top authority support, rising e-commerce demand, and new technological momentum), and (4) challenges (uncertain trade environment and increasing profitability pressure). Then this paper suggests strategies for China's air cargo suppliers to adapt to the pandemic.     

Nuclear bombs and economic sanctions

We examine the efficacy of trade sanctions when a target's action causes an irrevocable change in the status quo; for example, sanctions to stop a target's nuclear weapons development program. We find that when a sanctioning country cannot precommit to maintain sanctions long after a target becomes a nuclear power, sanctions are not only inefficacious but they backfire, spurring a target to intensify its effort to complete the nuclear program. If the nuclear program has several stages to complete, gradually increasing sanctions as the nuclear threat becomes more imminent may also backfire even though the program is potentially stoppable when sufficient pressure is applied earlier on. We also discuss the policy implications of our analysis.     

Political competition,tax salience and accountability. Theory and evidence from Italy

This paper argues that electoral competition may hinder rather than foster political accountability, especially when elected officers can choose among a number of tax instruments. We develop a political agency model showing that politicians in more competitive jurisdictions use less salient tax instruments more intensely. Defining salience as visibility or, analogously, as voters' awareness of the costs associated with specific government revenue sources, we argue that voters are less likely to hold politicians to account for the associated tax burden of a less salient instrument. This in turn implies that strategic politicians will more heavily rely on less salient revenue sources when electoral competition is stronger. Using data on Italian municipal elections and taxes over a 10-year period, we determine the degree of salience of various tax instruments, including property taxes (high salience) and government fees for official documents (low salience). We then show that mayors facing stronger competition for re-election use less salient tax instruments more intensely.     

Financing Renewable Energy Projects in Major Emerging Market Economies: Evidence in the Perspective of Sustainable Economic Development

This research paper aims to explore the role of FDI inflows and stock market development on the promotion of renewable energy consumption. Furthermore, study investigates the effect of renewable energy consumption on CO₂ emissions and economic output across a panel of Brazil, China, India, and South Africa. Study utilizes annual data from 1990 to 2012 and employs various robust panel econometric techniques. The findings confirm that both FDI inflows and stock market development play an important role in promoting renewable energy consumption. The results also reveal that renewable energy consumption helps to mitigate the growth of CO₂ emissions and promotes economic development.

The True Meaning of ‘Social Justice’: A Catholic View of Hayek

Hayek's well‐known dismissal of the concept of ‘social justice’ is examined and questioned. While basically agreeing with Hayek's critique, the author argues that we should not entirely reject this concept, although it is often used in a vague and emotional way – ‘social justice talk’. Drawing on the tradition of classical liberalism and Catholic social teaching, he makes the case for the true meaning of social justice, which applies to the basic legal and institutional framework of a society rather than the distributional outcomes of market processes.     

第三方支付相关基础法律问题探讨

第三方支付不是单纯的货币转移支付,而是与商业交易密切相关。互联网支付是典型的"担保支付",第三方为付款人的货币支付和收款人的货物交付进行了担保,有效保证了交易合同的全面履行,付款人支付的货币资金具有反担保保证金性质;预付卡支付和银行卡收单支付都是委托代理支付,预付卡支付第三方收到付款人的货币资金属于保管行为。

Trade Liberalization and Environmental Taxation in Federal Systems

The literature on trade liberalization and environment has not yet considered federal structures. In this paper, we show how the design of environmental policy in a federal system has implications for the effects of trade reform. Trade liberalization leads to a decline in pollution taxes, regardless of whether pollution taxes are set at the federal (centralized) or local (decentralized) level, and it increases social welfare. The effect under a decentralized system is smaller than if these taxes are set by the federal government, and pollution emissions therefore decline in this case. Moreover, majority bias interacts with trade liberalization if federal taxes are used.     

Educational Development in South Sudan: Conscious Design or Spontaneous Order?

Educational development is key to the future prosperity of South Sudan. Officially the situation appears bleak with up to 50 per cent of primary‐aged children out of school, high reported dropout rates and poor attainment. Those involved in the development of education, government departments, international agencies, individuals and communities are each following one of two different approaches as they seek to extend the reach of education. The article suggests that these different approaches arise because those involved hold to either a conscious‐design or a spontaneous‐order model for educational development. The article looks at the recent development of schools in Juba, the capital of South Sudan, in the light of these two theories and finds, despite the rhetoric of the official reports, that most growth is organic and that most recent educational development is emerging spontaneously.
