Club convergence and drivers of house prices across Turkish cities
(Emerald Publishing, 2021) Yılmaz, Mustafa Kemal; Yılmaz, Mustafa Kemal; Lokman, Gündüz; Yılmaz, Mustafa Kemal; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose – This paper aims to examine the convergence pattern of residential house prices in a panel of 55 major cities in Turkey over the period between 2010 and 2018 and to investigate the determinants of convergence club formations. Design/methodology/approach – The authors applied the log t-test to identify the convergence clubs and estimated ordered logit model to determine the key drivers. Findings – The results suggest that there are five convergence clubs and confirm the heterogeneity of the Turkish housing market. Istanbul, the commercial capital, and Mugla, an attractive tourist destination, are at the top of the housing market and followed by the cities located in the western part, particularly along the Aegean and Mediterranean coasts of Turkey. Moreover, the ordered logit model results point out that the differences in employment rate, climate, population density and having a metropolitan municipality play a significant role in determining convergence club membership. Practical implications – Large-scale policy measures aiming to increase employment opportunities in rural cities of central and eastern provinces and providing lower land prices and property taxes in the metropolitan cities of Turkey can help mitigate some of the divergence in the house prices across cities. Originality/value – The novelty of this study lies in employing a new data set at the city level containing 55 cities in Turkey, which is by far the largest in terms of city coverage among emerging market economies to implement the log t-test. It also contributes to the literature on city-specific determinants of convergence club formation in the case of an emerging economy.
Financial performance of emerging market companies during the COVID-19 pandemic: Moderating role of sustainability performance
(Emerald Publishing, 2024) Aksoy, Mine; Yılmaz, Mustafa Kemal; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose: This study aims to investigate whether sustainability performance (SP) served as a safeguard for firm profitability (FP) and enhanced corporate resilience in emerging markets during the COVID-19 pandemic. Design/methodology/approach: Using a sample of 1,091 firms in 25 emerging markets from 2017 to 2021, this study analyses the moderating role of SP on the relationship between FP and COVID-19 by using hierarchical linear modelling at three levels: (a) time-level; (b) firm-level; (c) country-level. Findings: The results indicate that during the years 2020–2021, emerging market firms with robust SP showed better FP in the midst of the COVID-19 pandemic. The findings also indicate that all dimensions of sustainability, i.e. environmental, social and governance (ESG), have significantly affected the FP in the post-COVID period. Hence, adhering to ESG principles aids in alleviating adverse financial repercussions during times of crises. Practical implications: This study provides valuable insights for companies and policymakers for finding solutions that may assist them in improving SP globally and enduring crises resiliently. The findings are also relevant to institutional investors that consider SP as an investment criteria. Although the COVID-19 pandemic was temporary, the lessons learned could protect firms from future similar global crises. Originality/value: This study enhances the understanding of the contingency relationship between sustainability and financial performance by offering up-to-date empirical insights within the context of emerging markets during the pandemic. It demonstrates how different institutional frameworks influenced the SP–FP association during the crisis. Thus, this paper expands the understanding of crisis management literature and bridges the research void concerning the impact of SP on FP in an emerging market context.
Untangling the influence of corporate sustainability on export intensity: The moderating role of R&D intensity
(SAGE Publications, 2024) Aksoy, Mine; Yılmaz, Mustafa Kemal; Gölgeci, İsmail; Tatoğlu, Ekrem; Cancı, Metin; Hızarcı, Atike Elanur; Yılmaz, Mustafa Kemal; Tatoğlu, Ekrem; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Growing global environmental and social issues have imposed increased pressure on firms to address sustainability challenges in international markets, with a particular focus on improving their export performance. This is of significant importance for emerging market firms aiming to expand their presence in international markets, as they are compelled to bolster their environmental and social sustainability capacity to enhance their export intensity. This study delves into the relationship between corporate sustainability and export intensity through a longitudinal examination of 141 firms listed on Borsa Istanbul from 2014 to 2021. The results suggest that corporate sustainability positively influences export intensity, and this influence is further positively moderated by research and development (R&D) intensity. Additionally, post hoc analysis employing supplementary data pertaining to the environmental, social, and governance dimensions of corporate sustainability reveals that environmental performance plays a positive role in shaping export intensity, with R&D intensity positively moderating this relationship. In summary, the findings underscore that exporting firms that effectively integrate impactful R&D intensity into their international business operations are likely to harness their sustainability strategies, particularly those related to the natural environment, to achieve higher export intensity.
Board characteristics and sustainability performance: Empirical evidence from emerging markets
(Emerald Publishing, 2022) Yılmaz, Mustafa Kemal; Dişli, Mustafa; Mohamed, Farah Finn Mohamud; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose – This study aims to investigate the effects of board attributes, i.e. board independence, gender diversity, board size and board activity, on the sustainability performance of 439 publicly-listed non-financial companies across 20 emerging countries over the period of 2010–2019. Design/methodology/approach – We use Refinitiv environmental, social and governance (ESG) performance scores and board attributes variables derived from Thomson Reuters Eikon database. We examined the relationship between board features and sustainability performance by using the dynamic panel two-step systemgeneralizedmethod of moments estimator. Findings – Overall, our findings suggest that smaller, gender diverse and independent boards that convene frequently achieve better sustainability performance. The authors document a positive relationship between board gender diversity and sustainability performance across a broad spectrum of sustainability indicators. The authors also find evidence that board independence has a positive impact on two sustainability performance measures, i.e. environmental and governance performance. Although board size does not influence aggregate sustainability measures (ESG score, ESG controversies, and ESG combined score), the authors find a negative relation between board size and governance performance. Finally, board activity seems only relevant in explaining ESG controversies, i.e. other things being equal frequently held board meetings significantly reduce sustainability issues (ESG controversies). Practical implications – The authors’ findings provide implications to support regulators and emerging market companies on how to improve sustainability performance through the design and use of specific governance mechanisms. These interventions will help resolve agency problems among different stakeholders and, in turn, benefit sustainability. Social implications – This study also has social implications because it sheds light on how companies may change their attitudes towards sustainable practices through adjusting their corporate governance structures to increase the welfare of the society. Originality/value – This study examines the behaviour of companies in emerging markets on sustainability performance by discussing a broad range of board characteristics and covering a large sample of emerging markets. Thus, it provides valuable insights to the companies for further growth opportunities in emerging markets.
Does board demographic diversity affect the dividend payout policy in Turkey?
(Emerald Publishing, 2022) Yılmaz, Mustafa Kemal; Khan, Ajab; Aksoy, Mine; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose – The purpose of this study is to investigate the impact of board demographic diversity on the dividend payout policy in Turkish capital markets. Design/methodology/approach –Using a sample of 67 non-financial companies listed on Borsa Istanbul 100 index from 2013 to 2018, this study examines the influence of board demographic diversity on dividend payout policies in Turkish capital markets. The authors also create a Demographic Board Diversity Index (DBDI) to estimate the composite cognitive diversity. The authors use dividend payment probability, dividend payout ratio, and dividend yield to measure the dividend policy and employ panel logit and tobit regression models. Findings – The results indicate that diversity in nationality, experience and educational background play an influential role in encouraging companies to pay high dividends, while gender, tenure and age diversity are insignificant in affecting dividend payments. The findings also suggest that the DBDI positively affects the companies in formulating the dividend payout policies. Finally, the findings show that the family-owned companies with diverse board members have a negative influence on dividend payment intensity. Originality/value – The results offer valuable insights for companies and policymakers in emerging markets to develop a more refined governance structure accommodating board demographic diversity attributes to mitigate agency conflicts between controlling and minority shareholders through setting up effective dividend payout policies.
Board diversity and export intensity: The moderating role of firm size
(Emerald Publishing, 2023) Yılmaz, Mustafa Kemal; Yılmaz, Mustafa Kemal; Aksoy, Mine; Yılmaz, Mustafa Kemal; Cancı, Metin; Ay, Alp; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Purpose – Building on resource dependence theory and contingency theory (CT) and focusing on an emerging market setting, this study investigates how demographic board diversity (BD) influences the export intensity (EI) of firms listed on Borsa Istanbul (BIST), with the moderating effect of firm size, as a contingency factor, on this interaction. Design/methodology/approach –Using a sample of 65 exporting firms listed on the BIST Industrials Index, this study explores how demographic attributes of board members, represented by the board diversity index (BDI), affects EI by employing panel data analysis over the period of 2016–2020. Findings – The results suggest that there is a negative relationship between BD and EI, but firm size has a positive moderating effect on the association of BD and EI, indicating that large firms with diverse boards are more prone to access foreign markets and make export. The findings further indicate that board size and CEO duality have a negative and significant effect on EI, while marketing intensity has a positive and significant impact. Research limitations/implications –The sample covers only public companies listed on the BIST Industrials Index, and the impact of board characteristics on the EI is analyzed for a limited time frame, i.e. from 2016 to 2020. Practical implications – The findings help business executives better understand the contribution of the firm size on the interaction of BD and EI and offers valuable insights to companies to gain a competitive edge in international markets. Originality/value – The study provides evidence on the effects of board attributes on the EI from the perspective of emerging countries. It also helps to gain a deeper understanding of how board Dynamics contribute to the internationalization of companies.
The effects of a US-China trade war on Sub-Saharan Africa: Pro-active domestic policies make the difference
(Elsevier, 2023) Nantembelele, Fatuma Abdallah; Arı, Ali; Yılmaz, Mustafa Kemal; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This study simulates the impact of the change in trade policy between the US and China on the trade volume and economic prosperity of Sub-Saharan Africa (SSA). To do that, we employ a Computable General Equilibrium (CGE) model based on the Global Trade Analysis Project (GTAP) with different scenarios focusing on increases in tariffs. The results show that the tariff increases negatively affect the US and China in terms of trade volume and economic growth, while it leads to trade diversion and creation for the SSA. This offers valuable opportunities in improving exports and economic growth, particularly for Ethiopia, Kenya, and Nigeria. On the sectorial level, the findings imply that agriculture, food, and oil and gas sectors are positively affected in terms of export volume, while mineral, metal and service sectors are negatively impacted by the trade war.
Performance evaluation of real estate investment trusts using a hybridized interval type-2 fuzzy AHP-DEA approach: The case of Borsa Istanbul
(World Scientific Publishing, 2019) Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Yılmaz, Mustafa Kemal; Kuşakcı, Ali Osman; Tatoğlu, Ekrem; İçten, Orkun; Yetgin, Feyzullah; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This study proposes a three-stage holistic methodology combining an interval type-2 fuzzy analytical hierarchy process (IT2F-AHP) and data envelopment analysis (DEA) to deal with the performance evaluation problems encountered in fuzzy decision environments. In the first stage, prospective inputs and outputs are determined by field studies. The second stage employs IT2F-AHP to identify the most appropriate performance indicators based on vague expert judgements. Finally, DEA is applied to the decision-making units (DMUs) based on the selected set of input and output measures. The proposed methodology proves its merit on a case study addressing the performance of real estate investment trusts (REITs) in Turkey during their ten-year journey of trading on Borsa Istanbul (BIST). The results demonstrate that the average scores for technical, pure technical and scale efficiencies are 66%, 80% and 80%, respectively. Considering the technical efficiency scores, Turkish REITs could have reduced their input factors by an average of 34%. The findings also reveal that the majority of Turkish REITs suffer from economies of scale and could have improved their performance by expansion.
Measuring the impact of board gender and cultural diversity on corporate governance and social performance: Evidence from emerging markets
(Taylor & Francis, 2022) Hacıoğlu, Ümit; Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Hacıoğlu, Ümit; Tatoğlu, Ekrem; Yılmaz, Mustafa Kemal; Yılmaz, Mustafa Kemal; Hacıoğlu, Ümit; Tatoğlu, Ekrem; Aksoy, Mine; Duran, Selman; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
This study examines the effects of gender and cultural diversity of boards on the corporate governance and social performance of 373 companies listed in 24 emerging country markets over the period of 2010–2019 using panel data analysis. A two-step system GMM model is also applied to test the endogeneity problem. The results indicate that gender and cultural diversity positively affect corporate governance performance. While we note that social performance is positively associated with both gender and cultural diversity, this relationship is insignificant. The findings offer multidimensional insights for companies, policy makers, and stakeholders to promote the association between gender and cultural diversity initiatives and corporate sustainability dimensions in emerging markets.
Moderating role of corporate governance and ownership structure on the relationship of corporate sustainability performance and dividend policy
(Taylor & Francis, 2022) Yılmaz, Mustafa Kemal; Aksoy, Mine; Khan, Ajab; Yönetim Bilimleri Fakültesi, İşletme Bölümü
The aim of this study is to investigate the influence of corporate governance and ownership structure on the relationship of corporate sustainability performance and dividend policy by using a panel dataset of 79 non-financial companies listed on Borsa Istanbul 100 Index for the years 2014–2020. We employed the panel logit, probit and tobit regression models for the analysis. The results indicate that corporate governance and family ownership significantly and positively moderate the relationship between corporate sustainability performance and dividend policy, while concentrated ownership and institutional ownership do not play a significant moderating role on this relationship. The findings also show that firm-level corporate governance is associated with high dividend payments, suggesting that this institutional mechanism helps reduce agency problems and lead companies to allocate capital more efficiently. The findings provide valuable insights for companies in structuring sustainability activities and shaping dividend policies with regard to ownership structure. It also offers policy prescriptions in emerging markets in the area of corporate financing policies.
