Do methane emissions converge? Evidence from global panel data on production- and consumption-based emissions

Methane emissions are the second most important contributor to global warming. Knowledge about the dynamics of methane emissions facilitates the formulation of climate policies and the understanding of their consequences. We investigate whether methane emissions released from production and embodied in consumption converge within and across regions. Our estimates rely on global panel data on methane per capita and methane intensities over 1997–2014. We find that emissions converge within countries. The short half-lives show that the emissions of countries are close to their steady states. There is no evidence for international convergence of aggregate emissions. Yet, convergence of emissions across regions occurs in a number of economic sectors. Our results highlight the difficulties to achieve methane abatement in the medium run. The formulation of climate policies should take into account the sectoral specificity of the dynamics of methane emissions.

Migration and Labor Market Integration in Europe

The European labor market allows for the border-free mobility of workers across 31 countries that cover most of the continent’s population. However, rates of migration across European countries remain considerably lower than interstate migration in the United States, and spatial variation in terms of unemployment or income levels is larger. We document patterns of migration in Europe, which include a sizable migration from east to west in the last twenty years. An analysis of worker-level microdata provides some evidence for an international convergence in wage rates and for modest static gains from migration. We conclude by discussing obstacles to migration that reduce the potential for further labor market integration in Europe.

The Current Situation of International Accounting Convergence and the Strategic Choice of International Convergence of Accounting Standards for Chinese Enterprises

With the deepening of world economic integration, IFRS has become more and more widely used worldwide. Under the new situation that the current international financial regulatory framework is being rebuilt, the international accounting landscape is undergoing major adjustments, and the international accounting standard setting agencies are actively promoting the reform of governance structure, my country needs to review the situation, follow the trend, and choose an international accounting standard that meets the needs of national conditions.

Development of mRNA Vaccines: Scientific and Regulatory Issues

The global research and development of mRNA vaccines have been prodigious over the past decade, and the work in this field has been stimulated by the urgent need for rapid development of vaccines in response to an emergent disease such as the current COVID-19 pandemic. Nevertheless, there remain gaps in our understanding of the mechanism of action of mRNA vaccines, as well as their long-term performance in areas such as safety and efficacy. This paper reviews the technologies and processes used for developing mRNA prophylactic vaccines, the current status of vaccine development, and discusses the immune responses induced by mRNA vaccines. It also discusses important issues with regard to the evaluation of mRNA vaccines from regulatory perspectives. Setting global norms and standards for biologicals including vaccines to assure their quality, safety and efficacy has been a WHO mandate and a core function for more than 70 years. New initiatives are ongoing at WHO to arrive at a broad consensus to formulate international guidance on the manufacture and quality control, as well as nonclinical and clinical evaluation of mRNA vaccines, which is deemed necessary to facilitate international convergence of manufacturing and regulatory practices and provide support to National Regulatory Authorities in WHO member states.

DEVELOPMENT OF LEGAL REGULATION OF ISSUES RELATED TO INFORMATION CONFIDENTIALITY AND PERSONAL DATA PROTECTION IN THE EUROPEAN UNION

The review summarizes scientific publications that reveal current problems in the field of legal regulation of confidentiality and data protection. It is noted that the General Data Protection Regulation (GDPR) is essential for the work of international organizations. At the same time, its action gives rise to questions about the relationship between EU law and public international law. Attention is focused on those legal values that are decisive in the formation of national and international approaches. The proposed in the scientific literature models of legal regulation of confidentiality and data protection, aimed at achieving international convergence.

Public policies and the art of catching up: matching the historical evidence with a multicountry agent-based model

In this article, we study the effects of industrial policies on international convergence using a multicountry agent-based model which builds upon Dosi et al. (2019b, J. Econ. Dyn. Control, 101, 101–129). The model features a group of microfounded economies, with evolving industries, populated by heterogeneous firms that compete in international markets. In each country, technological change is driven by firms’ activities of search and innovation, while aggregate demand formation and distribution follow Keynesian dynamics. Interactions among countries take place via trade flows and international technological imitation. We employ the model to assess the different strategies that laggard countries can adopt to catch up with leaders: market-friendly policies; industrial policies targeting the development of firms’ capabilities and R&D investments, as well as trade restrictions for infant industry protection; protectionist policies focusing on tariffs only. We find that markets cannot do the magic: in absence of government interventions, laggards will continue to fall behind. On the contrary, industrial policies can successfully drive international convergence among leaders and laggards, while protectionism alone is not sufficient to support catching up and countries get stuck in a sort of middle-income trap. Finally, in a global trade war, where developed economies impose retaliatory tariffs, both laggards and leaders are worse off and world productivity growth slows down.
