In Europe, particularly, a political momentum for hydrogen use has strengthened in recent years. This potential for massive development of low-carbon hydrogen technologies in the coming decades raises questions about the world's future dependence on mineral resources and the associated environmental impacts. The aim of this article is to address this issue by assessing the raw materials consumption associated with hydrogen development in Europe up to 2050. The results are based on an analysis of the European hydrogen development pathways resulting from the H24EU project. They highlight the importance of platinum-group metals in electrolysers deployment. Annual iridium demand for PEM electrolysers installed in the European Union could cause major supply tensions since it could reach 164% of its current global production by 2050. Nickel, cobalt, and copper, already associated with high risks of bottlenecks in the energy transition, are not left out: the development of alkaline electrolysis could contribute to a substantial increase in demand for these strategic materials.</p></div>","PeriodicalId":13794,"journal":{"name":"International Economics","volume":"176 ","pages":"Article 100457"},"PeriodicalIF":0.0,"publicationDate":"2023-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50178843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find evidence of a nonlinear relationship: the fiscal effects related to current account imbalances are differentiated among European countries. On the one hand, we find a positive elasticity of fiscal balance to current account balance when the quality of institutions is low. This suggests that in countries with high corruption, a deterioration of the current account results in a degradation of fiscal balance and an increase of debt. On the other hand, we find a negative elasticity of fiscal balance to current account balance when the quality of institutions is high. This implies that in countries with low corruption, larger current account imbalances can be related to an improved fiscal balance and a lower debt.

Our results show that oil prices and international geopolitical risk harm the KSA diversification process in the short run. The destructive effect of oil prices continues in the long run, while the impact of the international geopolitical risk does not persist. On the other hand, government expenditures encourage the diversification attitude in the short and long run. This outcome highlights the capability of the KSA government to stimulate the diversification process. It is a positive sign of the state capitalism doctrine's impact on the KSA economic diversification mechanism. From a policy implication perspective, our paper suggests prioritizing economic diversification clearly on the KSA government's agenda. Simultaneously, strengthening the KSA institutional framework and developing new forms of the social contract are critical to motivating the diversification process.</p></div>","PeriodicalId":13794,"journal":{"name":"International Economics","volume":"175 ","pages":"Pages 13-24"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49865081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, none of the existing studies have looked at the combined effect of these two on inequality. Our contribution to the literature is manifold. First and foremost, we examine whether remittances and financial development are substitutes or complements in reducing inequality and find evidence that, in countries that are more unequal, remittances substitute financial development in reducing inequality. But, in countries that are less unequal, remittances complement financial development in reducing inequality. Second, we find that the substitutionary effect of remittances is larger than their complementary effect. And finally, while previous studies have assumed that remittances and financial development have homogenous effects on inequality, we find that remittances and financial development exert heterogeneous effects across the conditional distribution of inequality.</p></div>","PeriodicalId":13794,"journal":{"name":"International Economics","volume":"175 ","pages":"Pages 171-186"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49865075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analysis of modularity conducted on both the trade agreements and the trade flows shows an imperfect correspondence between the communities of countries found within the two networks. Although the motivations of Brexit were multiple and, for the most part, far from commercial concerns, Brexit appears as a way to reconcile the networks of flows and agreements. On the other hand, Canada already belonged to the European cluster of trade agreements before the CETA agreement, which therefore appears only as an <em>ex post</em> confirmation of an existing situation.</p></div>","PeriodicalId":13794,"journal":{"name":"International Economics","volume":"175 ","pages":"Pages 1-12"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49865079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that competition negatively affects bank efficiency according to the current environment and structure of the WAEMU banking system. However, this relationship between competition and efficiency is non-linear and subject to a high threshold of competition. Furthermore, the results show that multinational banks are generally less efficient but more resilient to competition due to their level of capitalization, their ability to invest in innovation, and their networks. The estimates also show that corruption and political instability reduce bank efficiency and reinforce the negative effect of competition on efficiency.
