The main objective of this study is to analyze the mediating role of intellectual capital in the relationship between diversification, financial stability, and efficiency of the banking sector in Ethiopia.

Secondary data for this study was obtained from audited financial statements of 17 Ethiopian commercial banks for a decade starting in 2013. A descriptive and explanatory research design with a quantitative research approach was employed. The seemingly unrelated Hierarchical regression analysis is used to estimate diversification’s effect on banks' financial stability and efficiency, considering the interaction between diversification and intellectual capital as a mediating variable.

The Mediation analysis reveals that asset diversification improves the financial stability of commercial banks when mediated by intellectual efficiency. Investment diversification negatively impacts risk-adjusted return on asset and Z score. Intellectual capital significantly enhances commercial banks' efficiency and financial stability in Ethiopia and mediates the relationship between geographic diversification, financial stability, and efficiency. The mediation analysis also indicates that intellectual capital significantly mediates the relationship between income diversification and efficiency.

This study highlights the importance of intellectual capital and promotes its strategic allocation by management and regulatory bodies to enhance the financial stability and operational effectiveness of the banking industry in Ethiopia.

To the best of the researcher’s knowledge, this study is one of the rare attempts to investigate the mediating role of intellectual capital on the nexus between diversification, financial stability, and efficiency of commercial banks in Ethiopia.

The purpose of this study is to evaluate whether a diversification by grape varieties may help wine producers reduce uncertainty in quantity and quality variations due to increasingly erratic climate conditions.

This study hand-collects granular quantity and quality data from wine harvest reports for vintages 2003 to 2017 for the Valais region in Switzerland. The data allows us to obtain detailed data on harvested kilograms/liters and Oechsle/Brix degrees. It is then merged with precise meteorological data over the same sample period. The authors use this data set to capture weather conditions and their impact on harvested quantities and quality. Finally, they build portfolios including different grape varieties to evaluate whether this reduces variations in quality and quantity over vintages.

The findings highlight that the weather varies relatively strongly over the sample period and that climate hazards such as hail, frost or ensuing vine diseases effectively occur. These strongly impact the harvested quantities but less the quality of the wine. The authors further show that planting different grape varieties allows for a significant reduction in the variation of harvested quantities over time and thus acts as a good solution against climate risk.

The effect of climate change on viticulture is becoming increasingly important and felt and bears real economic and social consequences. This study transposes portfolio diversification which is central to reducing risk in the finance industry, into the wine industry and shows that the same principle holds. The authors thus propose a novel idea on how to mitigate climate risk.

This paper studies diversification and value in the investment portfolios of (non-listed) Real Estate Investment Funds (REIFs) exploring how the value of diversification is captured by the market and by investors (beyond reported valuations).

We apply the Herfindahl-Hirschman Index (HHI) to study the level of concentration versus diversification in the investment portfolios of REIFs (both in terms of segment and geographical diversification). We use a dataset from INREV with data from 62 investment portfolios, with an average of 86 REIFs per portfolio for the period of 2008–2020 (to study segment diversification). We use a second dataset from INREV with data from 30 investment portfolios with an average of 79 REIFs per portfolio for the period of 2005–2020 (to study geographical diversification). We employ a cluster analysis approach to identify common features among the investment funds.

We conclude that (segment diversified) portfolios with higher degrees of leverage exhibit higher income yields, albeit diversification is captured indirectly through asset choices – more diversified portfolios tend to exhibit a stronger risk and return relationship. Also, geographical diversification creates value (more significantly by for the correct combination of countries carefully choosing what different geographies to group in the diversified portfolio).

One limitation of our study is that our portfolios are funds of funds, since the available data could not reach the asset detail, but we believe this does not compromise our results.

Diversification leads to higher risk-adjusted returns which suggests that properties may be undervalued (market value) in the framework of the Gordon Model, contrary to expectations (regarding investment value).

Investors capture the value of diversification differently, suggesting a gap between market value and investment value that can be explored.

This study aims to examine whether diversified economies enhance the growth benefits from foreign direct investment (FDI). Diversified economies benefit from stable export earnings, stable investment composition and greater factor endowments through forward and backward linkages that can leverage superior foreign technology embedded in FDI. This is crucial as many African economies suffer from dependency while FDI is concentrated in the primary sector.

The authors use a dataset of 15 Economic Community of West African States from 1995 to 2020 and compile variables from various sources, including an export diversification index measured using the Herfindahl–Hirschman index of product concentration. The authors use a growth regression model estimated using dynamic panel estimators to control for endogeneity and simultaneity issues.

The results show that the effects of direct FDI are insignificant to growth considering diversification and controlling for other confounding factors. Meanwhile, diversification is associated with growth, which highlights the importance of industrial policy. More importantly, the authors find that the marginal effects of FDI are positively and significantly associated with growth when diversification levels are low, implying that production structure matters for the FDI–growth nexus in developing economies.

Previous studies have overlooked the role of export production structure on the FDI–growth nexus. Many developing economies are dependent on primary exports and suffer from dependency, which implies lower levels of factor endowments. As such, this reduces the growth gains from FDI. The authors provide new empirical evidence on the importance of export production structure on the FDI–growth nexus.

The aim of this paper is to determine whether the efficiency of banks’ human capital (HC) has moderating effects on the relationship between asset diversification and bank performance over the 2008–2020 period.

Our study considers generalized least squares estimation in fixed effects panel.

Results show that banks with higher levels of HC and higher degree of diversification reduce bank profitability and efficiency. The results also depict that the financial stability-reducing effects of Income diversification decrease as bank HC efficiency increases. At the same time, the effects of income and asset diversity on financial stability change depending on the performance aspect.

Previous research on banks’ performance is concentrated on asset diversification. This article broadens to the HC, Asset diversification and the moderating effects of the profitability, stability and efficiency of French Banks.

The purpose of this research is to apply the theoretical frameworks of resource-based view (RBV) and Social Creativity to elucidate insights related to food cultures and creative tourism in the context of Brunei. This addresses an important gap in the literature to unpack how food cultures and creative tourism can become a vehicle for the diversification of a country’s reliance on oil and gas as primary industries.

A case study approach was taken in this research, utilising both primary and secondary data such as social media posts, media reports and semi-structured interviews to shed light on an emerging niche market in Brunei tourism.

The research revealed the entrepreneurial mindset of local food chefs and enthusiasts in showcasing Bruneian heritage and cultures, supported by government campaigns and technological advances. This lends further evidence that food cultures and creative tourism can be a lever for a national economic diversification strategy and can be validated elsewhere.

This is one of the first studies to investigate the intersection of the RBV and Social Creativity to advance the theory and practice of tourism in South East Asia.

The intersection of food cultures and creative tourism within Brunei is dovetailed into the theoretical frameworks of the RBV and Wilson’s Social Creativity Framework. This is evidenced in a diversification strategy emerging from the case study of Brunei, where food is earmarked as a heritage resource and leverages individual, and in particular, young people’s creativity to generate a niche tourism market for the country.

The paper illuminates the role of technology as a vehicle for the discourses of creativity, reflexivity, education and economy to flourish. Through co-created content on social media, food heritage and creative tourism experiences are foregrounded and assisted by the entrepreneurs in reaching their desired audiences. Arguably, such tools helped the country alleviate the devastating impacts of COVID-19 and thrust domestic food tourism experiences into the spotlight, like other destinations.

This is one of the first studies to investigate the intersection of the RBV and Social Creativity to advance the theory and practice of tourism in South East Asia.

This paper aims to examine the impact of intra-industry trade on business cycle synchronization within the Economic Community of West African States (ECOWAS). ECOWAS region is characterized by limited intracommunity trade and a low level of foreign direct investment.

First, this research uses the two-digit level harmonized system classification to measure intra-industry trade, which is straightforward to interpret and compute, making it suitable for countries with low trade intensity. Second, it uses the system generalized method of moments (system-GMM) to examine the dynamic relationship between variables and address endogeneity concerns.

The results obtained from the system-GMM estimation reveal a positive and significant correlation between intra-industry trade intensity and business cycle synchronization, as well as an inhibiting effect of economic freedom on the relationship between intra-industry trade and business cycle synchronization. These results highlight the need to implement policies aimed at reducing tariff barriers, improving financial integration and intensifying production.

This research analyze the link between intra-industry trade and business cycle synchronization within the ECOWAS. It also analyze the role of economic freedom on the link between intra-industry trade and business cycle synchronization.

Drawing on the time compression diseconomies perspective and business network theory, this study examines how the international expansion of a business group’s pace, scope and rhythm affects its performance.

Panel data (1999–2013) from the top 100 Taiwanese business groups investing in globalization were collected.

The results show that international pace and rhythm have an inverse U-shaped relationship with business group performance, while the relationship between international scope and business group performance is U-shaped. This study highlights that international expansion is multidimensional and nonlinear and that the factors that shape nonlinear relationships between international processes and performance are different. Furthermore, family group involvement positively moderates the link between international scope and performance and negatively affects the relationship between international pace and performance. However, no significant effect is observed between rhythm and performance. High family business group involvement mitigates the impact of outsiders’ liability and managerial costs; moreover, it enhances the positive effects of location-specific advantages and business network resources.

This study combined the time compression diseconomies perspective and business network theory to explain why and how internationalization may not always lead to good performance by examining the effects of different international expansion processes and the interactive effect of family group involvement.

The purpose of this paper is to provide a systematic review of literature on corporate engagement with start-ups (CEWS) by identifying the modes, contexts, antecedents, barriers and outcomes. As an emerging field, CEWS presently has no such review available which will help in building consensus within the field and shape future research directions.

The study followed a two-phased systematic review of literature. Three research databases (i.e. Web of Science, ScienceDirect and SCOPUS) were accessed to gather and conduct the review. Of the total 379 papers retrieved, 63 total relevant papers were studied and analysed. The exhaustive review of literature helped to uncover the contexts, perspectives, antecedents, outcomes and barriers reported across the different modes of CEWS.

The study highlighted the five prominent modes of CEWS favoured by large corporations and start-ups. It found that the large corporations and start-ups associate with one another on the basis of complementarities of activities, resources and motives to pursue their strategic orientations. The engagements also face barriers on the ground, such as incompatibility of goals, power imbalances, cultural differences and weak engagement plans. Most important contexts seen were the high-technology industries in the developed economies like the USA and Europe. It also found that ecosystem creation, accessing innovation and corporate strategy have been preferred as the most productive modes of CEWS in the literature.

This review provides practitioners with a detailed list of the modes and drivers of CEWS. Subsequently, the barriers that need to be managed to successfully execute a specific mode of engagement. This shall enable the practitioners in developing and adopting the best practices while engaging with the start-ups to better facilitate the outcomes of CEWS.

To the best of the authors’ knowledge, there is no systematic literature review available in the domain of CEWS – thus, this study makes an important methodological contribution to the field. By consolidating the fragmented yet growing knowledge on CEWS, the study presents a detailed understanding of what drives and obstructs the engagement between large corporations and start-ups.

This paper aims to examine the short-term market reaction for the world’s 100 largest listed defence firms at and around the three recent largest threats to the global economy – Ukraine–Russia war, Fourth Taiwan Strait Crisis and the Hamas terrorist attack on Israel.

The author examine the impact of the three recent largest threats to the global economy in the largest listed defence firms using an event study methodology.

The results show a positive and statistically significant short-term reaction around the three geopolitical threats. The results also reveal the existence of higher abnormal returns for defence firms with greater weight of defence sales, in line with the captured regulator theory and for firms with higher research and development and capital expenditure intensity.

The effect of the war on stock markets has been relatively little examined in the financial theory. This study intends to fill this gap in the literature through the analysis of the three recent largest threats to the global economy.
