This study aims to investigate the impact of international diversification on the value and operating efficiency of European real estate firms.

The study is conducted using a panel fixed effects regression model to estimate the relationship of international diversification with firm value and operating efficiency. International diversification is mainly measured via the negative of the Herfindahl–Hirschman Index (HHI) using property-level data. Firm value and operating efficiency are proxied by financial ratios observed annually from 2002 to 2021 at the firm level.

The results demonstrate that international diversification has a negative effect on firm value. Additionally, it lowers operating efficiency by weakening a firm's ability to generate operating earnings from its assets. By examining whether the reduction in operating efficiency is due to the rental income channel or the capital gains channel, the authors find strong statistical evidence that international diversification negatively impacts capital gains. International diversification is negatively associated with net gains from property valuations (unrealized capital gains) and net profits from property disposals (realized capital gains).

The empirical analysis is limited to Europe.

This paper extends the geographical diversification literature. While existing literature focuses on domestic diversification within the United States, this paper explores the effects of international diversification on European real estate firms. To the extent of the authors' knowledge, this is the first paper to examine the impact of geographical diversification on capital gains.

This research aims to empirically investigate the impacts of product and international diversification strategies on firm-level inventory performance.

This study empirically examines the associations between product and international diversification strategies and inventory performance based on a sample of 64,124 observations across 7,367 US publicly traded firms between 1989 and 2019 from the COMPUSTAT Segment, Fundamental Annual and Fundamental Quarterly data files. We employ both linear and nonlinear regression models to perform our empirical analysis.

This research provides strong evidence that there exists a U-shaped relationship between unrelated product diversification and inventory level and a partially inverted U-shaped relationship between international diversification and inventory level. We also find a positive impact of related product diversification on inventory level, but there is no significant curvilinear relationship between related product diversification and inventory level.

Our research findings offer important insights into top management’s strategic planning for diversification strategies and operations manager’s inventory control policies to achieve the strategic fit between corporate diversification and inventory management.

Product and international diversification strategies not only play an essential role in the firm’s competitive advantage, but also have a significant influence on operations manager’s inventory decision. This research is among the first to systematically investigate how top management’s related product, unrelated product and international diversification strategies may have complex nonlinear impacts on inventory performance.

Uncertainties caused by political risks can drastically affect global supply chains. However, the supply chain management literature has thus far developed rather limited knowledge on firms' perception of and reactions to increased political risks. This study has two main purposes: to explore the relationship between extant risk exposure and perceived firm-specific political risk and to understand the impact of firm-specific political risk on firms' vertical integration and diversification strategies.

The authors developed a unique dataset for testing our hypotheses. Specifically, the authors sampled manufacturers (SIC20-39) listed in the United States from 2002 to 2019. The authors collected financial and diversification data from Compustat, vertical integration data from the Frésard-Hoberg-Phillips Vertical Relatedness Data Library and political risk data from the Economic Policy Uncertainty database. This data collection process yielded 1,287 firms (8,329 observations) with available data for analysis.

A two-way fixed-effect regression analysis of panel data revealed that firms tend to be more sensitive to political risk when faced with income stream uncertainty or strategic risk. By contrast, exposure to stock returns uncertainty does not significantly influence firms' sensitivity toward political risk. Moreover, firm-specific political risk is positively associated with vertical integration and product diversification. However, firm-specific political risk does not result in higher levels of geographical diversification.

This study joins the literature that systematically explores the antecedents and implications of firm-specific political risk, thus broadening the scope of supply chain risk management.

This paper aims to explore the value of geographic diversification in the context of deglobalization, drawing evidence from a quasi-natural experiment – the Brexit referendum that took place on 23 June 2016 in the UK.

This study applies an event study methodology to estimate the impact of the Brexit vote on a cross-section of firms with varying levels of geographic diversification – undiversified UK firms, UK firms with significant operations in the European Union (EU) and globally diversified UK firms. This study deploys a Heckman two-stage regression approach to address sample selection bias.

This study finds that undiversified UK firms experienced negative cumulative abnormal returns (CARs) around the Brexit referendum. The value of UK firms with majority sales within the UK declined by 0.9 percentage points, on average, in the three days centred on the Brexit referendum. In contrast, UK firms that are globally diversified, with the majority of sales within the EU are unaffected, while diversified firms in the rest of the world generated positive CARs of 1.8 percentage points over the same period. These results are robust to firm characteristics, selection bias and alternative measures of CARs and diversification.

This study is subject to some limitations that open avenues for future work. There are a few available proxies of diversification and further work on developing other proxies is much needed. Further work may also examine the long-term impact of diversification on UK firms. This study considered Brexit as a quasi-natural experiment, and this study could be applied to other deglobalization events like COVID-19 and can enhance the generalizability of diversification strategy in the deglobalized world. Findings may stimulate future work to explore how another form of diversification – product diversification has affected firm returns around Brexit. Finally, this study has focused on the UK as its base case. It may be interesting to corroborate the findings by exploring the impact of Brexit on European firms, who hitherto Brexit, had some operations in the UK.

This work offers some insights for policymakers and regulators around the impact of deglobalization on local firms. Findings suggest that these trends significantly negatively impact the most vulnerable firms (smaller firms with less global reach), while their larger counterparts with significant global reach might be insulated. This finding is important for determining the nature of support needed by different firms in times of deglobalization. The work also offers insights to managers of firms operating in countries where there are real prospects of deglobalization. Specifically, the work highlights the importance of geographic diversification when free movement of goods, services and people is restricted.

This study shows that a certain group of globally diversified firms earned significantly higher returns from the prospect of the UK leaving the EU, thereby highlighting the value of geographic diversification in a time of deglobalization.

This study aims to investigate the impact of corporate diversification and growth opportunities on the performance of real estate investment trusts (REIT) in Malaysia and Singapore before and during the pandemic.

The sample consists of 33 public-listed REITs across Singapore and Malaysia. A dynamic panel system generalized method of moments (DPS-GMM) estimation is used to account for unobservable factors and a relatively short sample period (2009–2022).

Results indicate that the impact of diversification is contingent on the market where the REIT is based and other institutional factors. The estimates also show that diversified REITs are better able to weather period of economic uncertainty.

We provided a definitive answer as to why corporate diversification leads to conflicting outcomes – market and institutional factors, strategic intent and the overall economic environment. We also show that the impact of typical firm controls (i.e. free cash, size) can differ. Future firm-level work should thus study similar phenomenon more contextually and carefully consider these varying effects.

The literature is divided on the impact of diversification on firm performance. By using a two-country sample, we show conclusive evidence that this contradictory outcome is due to market and institutional factors. We also show evidence that strategic intent is an important factor that influences the outcomes of diversification, regardless of market. We also infer that excess cash aids the resilience of the firm, contrary to the negative perception of excess cash during normal times. Firm size, in contrast, does not contribute to firm performance during a crisis.

The manufacturing sector plays an important role in any economy. The sector opts for diversification techniques and CSR initiatives in a competitive business environment for growth, survival and reputation. This study examined the impact of corporate diversification and CSR on the financial performance of South Asian manufacturing firms.

Data is obtained from the financial statements of 350 listed South Asian manufacturing firms as well as the respective stock exchanges of these countries. The data for research analysis ranges from 2010 to 2020. Diversification is measured using product diversification and geographic diversification. CSR is quantified in terms of social contribution value. Accounting measurements (ROA and ROE) are also used to capture corporate performance. For hypothesis testing, the study also uses fixed effect panel regression, and for assessing the robustness of the findings, the two-step dynamic panel system-GMM regression approach is used.

Findings of study indicate a positive impact of product and geographic diversification on financial performance measured with ROA. However, geographic diversification is insignificantly linked with ROA and ROE. Further, CSR positively impacts the performance of firms in South Asia with both performance measures.

The study has several policy implications based on the findings, including the need for the manufacturing sector to practice and implement appropriate diversification approaches and CSR initiatives to improve its financial performance and reputation.

This study explores the effect of income diversification strategy on credit risk and market risk of microfinance institutions (MFIs) in Ghana as an emerging market.

The study is based on quarterly data of averagely 271 MFIs that have operated from 2016 to 2018. The dataset is unbalanced and pooled cross-sectional with 3,259 data points. The study measures the diversification strategy using income diversification indices, and accounting ratios to measure the other variables. We utilised the weighted least squares (WLS) approach to explore the nexus.

The findings show that income diversification is associated with better loan quality and credit risk management. Market risk increases with the level of income diversification of microfinance firms. It is evident that large MFIs can manage their credit risks well and can have a low default rate, depicting an overall U-shaped nexus. On the other hand, the effect of size on market risk is an inverted U-shaped. The effect of asset tangibility on credit risk is positively significant while the effect on market risk is negatively significant. High profitability enhances credit risk management leading to lower loan losses while in the case of diversified and profitable MFIs, they tend to invest more in government securities. The results suggest that MFIs that hold more cash and cash equivalents tend to have high loan loss provision and more government securities suggesting much attention should be paid to optimal cash management.

The results throw light on the credit risk and market risk profile of the firms and the effect of diversification strategies on them. The findings are relevant for effective macroprudential regulation, market regulation and prudential regulation of the microfinance sector.

The findings reveal the nature of income diversification strategy of MFIs in emerging markets such as Ghana, pointing out how they affect the risk exposure of MFIs that lend to the pro-poor population.

This is a premier formal assessment of the nexus between income diversification strategies and risk management among MFIs that serve the pro-poor population in the emerging market context.

This paper aims to derive and estimate a theory-based empirical specification that models a firm’s choices of its international diversification (ID) and product diversification (PD) and how they evolve over time in response to shocks that alter the relative cost and relative profitability of ID and PD.

We use longitudinal data on U.S. manufacturing firms from 1984 to 1999, a period of intense shocks associated with rapid globalization, to estimate a dynamic panel data Tobit model that permits lags in a firm’s adjustment to its optimal mix of ID and PD over time.

We find strong support for the theoretical framework underlying our empirical specifications and posited dynamics, with full adjustment estimated to require, on average, 1.5 years, a finding with implications for the time spacing of observations in empirical studies of ID and PD to avoid biased inferences. Among the globalization shocks during the time period studied, our results indicate that global competitive pressures and efficiency gains from global supply integration to be the more important factors driving U.S. firms toward greater ID relative to PD. Augmentation of firms’ organizational (managerial) and physical capital resources is also found to be important for supporting an expansion of ID relative to PD. Technological resource augmentation is instead found to favor expansion of PD relative to ID.

Our empirical specification is novel. It readily incorporates an often ignored but necessary theoretical condition that defines a firm’s optimal choices of its ID and PD, and it allows observed choices at a point in time to deviate from their optimal values.

This study aims to explore the determinants (bank-specific, industry-specific and macroeconomic) of income diversification across interest income and non-interest income as well as for non-traditional income sources (non-interest income) from 2004–2005 to 2021–2022.

An unbalanced data set comprising 110 Indian commercial banks with 1480 observations is sampled in this study. Because of the bounded nature of the dependent variables (proxies of income diversification), the panel Tobit regression model is used.

The findings reveal that income diversification is positively influenced by bank size, technological advancements, cost–income ratio, return on assets, market competition and inflation in the economy. However, the decision to diversify income sources is adversely impacted by the capital ratio, GDP and financial intermediation ratio. Moreover, factors such as asset quality (loan loss provisions) and liquidity ratio do not directly influence the diversification strategies in the Indian banking industry.

The present study uses an extensive set of variables to provide insights into key factors for bank managers, regulators and policymakers to consider before developing diversification strategies.

To the best of the authors’ knowledge, this is the first study to examine the various bank-specific and macroeconomic determinants that affect income diversification in the Indian banking sector. The current study also investigates new variables such as technological advancements and a market concentration index for measuring competition, which have not been investigated in existing literature concerning bank income diversification in the Indian context.

The purpose of this study was to explore the motives (especially the agency motives) for corporate diversification from the perspective of corporate executives who make such strategic decisions and manage the diversified firms daily.

A qualitative research approach was adopted, and 12 chief executive officers (CEOs) of diversified firms in Nigeria were interviewed for their perspectives on the motives for corporate diversification.

Stewardship motives – diversification to use excess capacities in assets and resources to exploit opportunities in the market and defend against adverse environmental developments – were the most cited reasons for diversification. The relevant agency problem related to corporate diversification motive in Nigeria is the principal–principal (majority shareholder-minority shareholder) one. CEOs with substantial holdings in their firms indicated that they use diversification to reduce their investment risk and retain control of their portfolio.

The findings suggest that in corporate environments such as Nigeria that feature blockholding prominently, the corporate strategy-related agency problem that policymakers should pay greater attention to is the principal–principal conflict rather than the traditional agent–principal problem that has influenced corporate governance over the years. There is also a need to revise the dominant view that diversification is a value-destroying strategy motivated by the self-seeking behavior of managers who have little or no shares in the companies they manage.

The few studies on motives for corporate diversification that incorporated the perspectives of corporate executives did not address the agency motives of diversification. To the best of the authors’ knowledge, this is the first study that has done so.
