Indeed, we examine the relationship between natural resources, economic complexity (EC), institutions environment, and industrialization with data spanning the period 2000–2019 for 17 leading African countries. Backed by empirical analysis with OLS for baseline estimations, robustness with additional control variables for attrition bias issues, 4-years average data that eliminates short-run fluctuations, quantile analysis for differentiated countries heterogeneous threshold effects, 2SLS instrumental variables and two-step system Generalized Method of Moments that resolve endogeneity concerns, we show that natural resources can enhance industrialization. We demonstrate that moving to higher levels of natural resources rents, EC that captures the amount of knowledge and know-how embodied in the products each country produces, and higher level of institutional quality considered as the backbone of the economy, also leads to a better level of industrialization. More so, by testing interaction effects between natural resources and EC associated with NRs and quality of institutions index, the impact of NRs on industrialization is positive and statistically significant unlike the well-known Dutch disease theory.</p>\u0000 </div>","PeriodicalId":46233,"journal":{"name":"Bulletin of Economic Research","volume":"78 2","pages":"410-442"},"PeriodicalIF":1.2,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large spikes in the level of connectedness are noticed around COVID-19 pandemic and Russia–Ukraine conflict, and Bitcoin and Ethereum emerge as net transmitters of returns and volatility shocks, emphasizing their significant role around these crisis periods. Notably, a strong positive rank correlation exists between the return and volatility layers, highlighting the significant risk–return relationship in the digital asset class.

We cluster at the company level in order to allow for multiple campaigns per company. The importance of allowing for truncation is confirmed using the Hausman test. Moreover, allowing for truncation alters the conclusions arising from previous literature concerning the effects of standard variables, including target amount, amount of equity offered, and number of team members participating in the venture.

The empirical section uses panel data from 30 Chinese provinces from 2000 to 2020. Employing the entropy method and data envelopment analysis (DEA), we measure the levels of the financial eco-environment and capital allocation efficiency in China.

However, the short-term negative effects of FGI on other SPs shift in the medium and long term. Furthermore, results from the sub-sample analysis indicate that market uncertainty stemming from the pandemic and the Russia–Ukraine war heightens investors’ risk aversion towards the stock market, resulting in a sharp short-term decline in SP.
