Globalisation is often depicted as having led to an increase in private authority at the expense of that of the state. It is important to correctly specify the scope that private authority has achieved and the capacity of states to push back and limit that authority. This article grounds these theoretical issues in a discussion of the hybrid, public–private dispute settlement mechanism set up in the original Canada–US Free Trade Agreement (CUSTFA), and later extended into Chapter 19 of the North American Free Trade Agreement (NAFTA). It finds that privatising the enforcement process did make a difference. Trade experts on panels saw things differently to judges and in ways that were more sympathetic to exporters. This favoured Canadian and Mexican interests. However, the arrangement lacked deep roots. It was a late-stage compromise in trade negotiations. This rendered it vulnerable to a US counterattack once panels began to rule in favour of Canadian and Mexican challenges to US trade determinations. The transfer of quasi-judicial authority to a public–private hybrid proved contingent, partly on the hegemonic state's ongoing level of comfort with the arrangement, as well as on a lack of business consensus within the United States.  相似文献

This study examines the association between COVID-19 mortality rates and internal conflict and investigates the possible moderating role of government economic support during the pandemic years of 2020 and 2021. Our main hypothesis suggests that countries with lower levels of government economic support are more likely to experience a positive correlation between higher COVID-19 mortality rates and the emergence of internal conflict. Using cross-country data from over 100 countries and controlling for various factors that may influence internal conflict, our analysis provides some support for this hypothesis. The results suggest a possible moderating role for government economic support, with the evidence indicating a weakening or elimination of the association between COVID-19 mortality rates and internal conflict when government economic support is adequate. However, the moderating effect of government economic support is not always significant, and caution is needed when interpreting the results. Our analysis also highlights the potential risks associated with low levels of government economic support during the pandemic. Specifically, we find that in countries where the government's macro-financial package in response to the pandemic is less than approximately 25% of GDP, there is a possible risk of growth in civil disorder resulting from increased COVID-19 deaths per million.  相似文献

We examine the effect of COVID-19-induced lockdown on the profitability of listed firms in India. We use quarterly income statement of 4168 listed firms for the period between April–June 2020 quarter and April–June 2022 quarter and compare their financial data with previous quarters (2015–2019). Using a difference-in-difference estimation framework and various profitability measures, we find that the COVID-19 lockdown has reduced profits by around 15 per cent for listed firms in India. Our results are robust to various robustness tests and alternate specifications. We find evidence of firms losing revenues more than expenses, thus leading to decline in profits. The main effect is conditioned by firm-specific factors. Specifically, firms that are smaller, older, unlisted and that do not belong to any group witnessed larger decline in profitability due to lockdown. Additionally, the effect of lockdown is more pronounced in areas that had lower mobility and higher COVID-19 spread. These results underscore the importance of institutional factors and pre-existing firm characteristics in conditioning the impact of lockdown on firm profitability.  相似文献

The coronavirus pandemic has led to revenue loss for tourism enterprises and workers due to restrictions on movement. In response, governments have made available temporary financial support, but not to those tourist enterprises and workers in the undeclared economy. Reporting a 2019 Eurobarometer survey, this paper reveals that one in 165 European citizens engage in undeclared work in tourism and the groups involved. To bring these enterprises and workers onto the radar of the state, a voluntary disclosure initiative is advocated offering access to the temporary financial support for undeclared enterprises and workers disclosing their previous undeclared work.  相似文献

With COVID-19 spreading around the world, many countries are exposed to the imported case risk from inbound international flights. Several governments issued restrictions on inbound flights to mitigate such risk. But with the pandemic controlled in many countries, some decide to reopen the economy by relaxing the international air travel bans. As the virus has still been prevailing in many regions, this relaxation raises the alarm to import overseas cases and results in the revival of local pandemic. This study proposes a risk index to measure one country's imported case risk from inbound international flights. The index combines both daily dynamic international air connectivity data and the updated global COVID-19 data. It can measure the risk at the country, province and even specific route level. The proposed index was applied to China, which is the first country to experience and control COVID-19 pandemic while later becoming exposed to high imported case risk after the epidemic centers switched to Europe and the US afterward. The calculated risk indexes for each Chinese province or region show both spatial and temporal patterns from January to April 2020. It is found that China's strict restriction on inbound flights since March 26 was very effective to cut the imported case risk by half than doing nothing. But the overall index level kept rising because of the deteriorating pandemic conditions around the world. Hong Kong and Taiwan are the regions facing the highest imported case risk due to their superior international air connectivity and looser restriction on inbound flights. Shandong Province had the highest risk in February and early March due to its well-developed air connectivity with South Korea and Japan when the pandemic peaked in these two countries. Since mid-March, the imported case risk from Europe and the US dramatically increased. Last, we discuss policy implications for the relevant stakeholders to use our index to dynamically adjust the international air travel restrictions. This risk index can also be applied to other contexts and countries to relax restrictions on particular low-risk routes while still restricting the high-risk ones. This would balance the essential air travels need and the requirement to minimize the imported case risk.  相似文献

We provide a model in which irrational investors trade based upon considerations that have no inherent connection to fundamentals. However, trading activity affects market prices, and because of feedback from security prices to cash flows, the irrational trades influence underlying cash flows. As a result, irrational investors can, in some situations, earn abnormal (i.e., risk-adjusted) profits that can exceed the abnormal profits of rational informed investors. Although the trading of irrational investors cause prices to deviate from fundamental values, stock prices follow a random walk.  相似文献
