Regions are gaining importance as globalization struggles with local sustainable implementation. Thus, regional integration assumes economic development based on transnational cooperation, including regionalization and regionalism. The New Silk Road (NSR) offers a set of policies (including the Belt and Road Initiative) for regional integration that faces challenges in geopolitics and geoeconomics with problems at the local and regional scale, especially along its core corridor, namely, the Eurasian Land Bridge. Therefore, we focus on the NSR implementation by examining the scenarios for future regional integration along the NSR in Eurasia. Using a stepwise scenario building method, including a literature review and qualitative interviews, four scenarios are outlined to explore regional cooperation and the impacts: from (1) withdrawal/reduction of the NSR towards (2) solo efforts by Chinese shareholders, (3) corridorintegration and finally, (4) deep regional integration. This study examines the interface between economic geography and international relations.

This article investigates the impact of external debt on economic convergence in 201 economies from 1990 to 2020. Panel data collected from the fiscal space database of the World Bank are analyzed using the conditional beta convergence framework. Results show that external debt negatively affects growth and there is no evidence to support the non-linear association. However, external debt influences the convergence speed in an inverted-U-shaped fashion. The economic convergence speeds up as the level of indebtedness increases to a threshold above which the convergence slows down as the level of foreign debts continues to increase. We also disaggregate external debt into its six sub-components and discover the non-linear effects of private debts and debts denominated in domestic currency on the convergence process.

Our research focuses on the relationship between the ESG performance of South Korean multinational companies and stock price crash in next year. For our study, we divide samples into three different categories - namely, all companies, multinational companies (MNC) and non-multinational companies(non-MNC). Our major findings are as following. First, we find the negative relationship between the social (S) score of multinational companies and future price crash, indicating that their social performance prevents price crash risk. Second, when individual ESG performance is considered, there exists negative relationship between environmental (E) and social (S) score, and future price crash for multinational companies. Lastly, we find negative relationship between the ESG score and future price crash, which is due to the high environmental (E) and social (S) score of MNCs, which, in turn, raise each respective score for all companies, which has high correlation with their ESG scores. In this research, focusing on features of ESG on price crash in Korean MNCs, we identify the mitigating effect of social (S) factor for the MNC, which is in consistence with previous researches.

We investigate Egypt's Taylor rule (interest rate targeting) between 1976 and 2019 by including the main economic variables in its reaction function. Using the Taylor principle, we investigate Egypt’s monetary policy optimality. To this end, we conduct the generalized method of moments (GMM) estimation procedure with different Taylor rule specifications to deal with potential endogeneity among variables. Our GMM estimates reveal that the partial adjustment coefficient is of considerable magnitude, indicating the explanatory power of policy inertia on many total variations in the current values of the nominal interest rate in Egypt. Furthermore, the inflation gap coefficient violates the Taylor principle, making the policy procyclical and inflation "spiral" and inducing divergence from the long-run equilibrium. Therefore, Egypt's Taylor rule, and thus monetary policy, reflects the indeterminacy of equilibrium and is a passive and destabilizing policy. Besides, the output gap coefficient was unexpectedly found to be insignificant.

The present evolutionary phase in international economic and political relations involves the analysis of a "new globalization" and the profound reshaping of multipolarity. This article examines the fundamental elements of the newly emerging globalization morphology from a critical standpoint on the key aspects of the Regional Comprehensive Economic Partnership (RCEP). It aims to discern why such free trade agreements are significant expressions and imprints of the unfolding new multipolarity. It focuses on crucial dimensions of such international socioeconomic agreements for deepened global cooperation and development. For the analysis, we distinguish between the structures of the previous globalization regime and some evolutionary dimensions of the gradual transition to a "new globalization" (e.g., the RCEP). We contend that such agreements enrich regional economic and social integration and can expand globalized transnational flows, thereby boosting efficient cooperation for reconstructing future dynamics of international economic development.

This paper explores the dynamic interactions between natural resource dependence, corruption, and tax revenue mobilization worldwide. The empirical analysis used a cross-section augmented autoregressive distributed lag (CS-ARDL) approach that accounts for time dynamics, cross-sectional heterogeneity, and cross-sectional dependence. The results show that the interaction between natural resource dependence, corruption, and tax revenue mobilization is complex and depends on the type of tax revenue. For example, reducing corruption stimulates non-resource tax revenue mobilization compared to total tax revenue; however, tax revenue mobilization is sometimes a source of corruption and evasion of natural resource rents. The results suggest that tax administration institutions need to be strengthened to limit predatory and rent-seeking behavior.

Macao was a Portuguese colony until 1999, when its sovereignty was transferred to China, initiating its integration process. This article attempts to estimate the consequences of this socio-economic process in terms of per capita gross domestic product (GDP). We build a panel data set spanning 1970 to 2012, with 25 countries, setting 2000 as the initial treatment year for the integration process. The analysis is carried out through two alternative methodologies: the synthetic control method and the panel data approach. The integration treatment had a significant, positive effect on Macao’s per capita GDP. As additional outcome variables, we also analyze the effects of integration on the per capita net inflow of foreign direct investment, the unemployment rate, and the per capita exports and imports of goods and services.

This study investigates the effect of the Internet on tax revenue instability (TRI), notably through the international trade channel. It used a sample of 142 countries over the period 1995-2017 and relied primarily on the two-step system generalized method of moments estimator. The findings indicate that greater access to the Internet negatively affects TRI, and this effect works through the trade openness avenue. Especially, countries enjoy a higher negative effect of the Internet on TRI as they experience a greater trade openness. Moreover, Internet access reduces TRI in countries that have experienced a greater extent of tax reform and a greater export product concentration. Therefore, these findings add to the potential benefits of Internet adoption by showing that it could also help stabilize tax revenue, particularly through countries’ participation in international trade.

This study documents the adjustment in the business cycles of Mexico’s states that resulted from trade liberalization. It also analyzes the relevance of the various elements that previous studies have proposed as the determining factors of the synchronization of these cycles. Our results reveal that these determinants are relevant throughout the sample period (1980-2019), but their relative importance changes over time as does their synchronization. This may be explained as follows: trade liberalization caused a regional and sectoral reallocation of resources, which in turn led to some states becoming increasingly interlinked based on their economic structures, whereas the remaining states became less synchronized with the former states. This case should be of interest to other developing countries that are dependent on the world’s capital and trade flows and whose regions may respond heterogeneously if they have diverse economic structures as those of Mexico.

This paper examines existing empirical research regarding the importance of competition and competition policy for variables relevant to macroeconomic outcomes. This research provides evidence on the correlations between competition, competition policy, and macroeconomic outcomes, such as productivity, growth, innovation, employment, and inequality. Competition policy is demonstrated to bring multiple benefits for macroeconomic outcomes in several economic studies. Gains from enhanced competition can essentially be divided into efficiency and redistribution effects. Efficiency gains result from the positive impact of competition on productivity growth, which allows firms and industries to produce more and better products and services at lower cost, whereas redistribution effects are associated with the impact of competition on inequality and employment in the market.
