This essay comprises a selection of commentaries aimed at creating dialog around the theme Bringing Excitement to Empirical Business Ethics Research (ins...
Article
In this study, we use board reforms across countries as a natural experiment to examine the effect of governance on firm leverage. We find that board reforms are associated with a statistically significant 1‐percentage‐point increase in leverage overall and a 5‐percentage‐point increase on average for firms that had to make large board changes. The...
Article
The COVID-19 pandemic has led to economic and health crises (“twin crises”) worldwide. Using a sample of firms from 73 countries over the period January to December 2020, we examine stock price reactions of multinational corporations (MNCs) and purely domestic companies (DCs) to the crisis. We find that, on average, MNCs suffer a significantly larg...
Article
In this paper, we exploit the immediacy, magnitude, and global extent of the COVID-19 shock to investigate the role of national culture in determining differences in publicly imposed social distancing restrictions. Employing the Stringency Index of the Oxford Covid-19 Government Response Tracker database for 85 countries, we find that countries wit...
Article
In this article, we examine the effects of economic policy uncertainty (EPU) on insider trading. Two hypotheses predict that EPU is positively related to insider trading volume and profitability: (1) the private benefits hypothesis, which states that insiders exploit their information advantage to realize abnormal profits, and (2) the signaling hyp...
Article
Event studies are widely used in finance research to investigate the implications of announcements of corporate initiatives, regulatory changes, or macroeconomic shocks on stock prices. These studies are often used in a single-country setting (usually the U.S.), but little work has yet been conducted in an international context, perhaps due to the...

With an emphasis on deliberative processes that occur between managers and stakeholders, the political corporate social responsibility (PCSR) literature has made important advances to our understanding of CSR activities. However, these contributions have tended to focus exclusively on organizational settings. We contend that an understanding of fir...
Article
Using a sample of cross-listed firms from 51 countries and a difference-in-differences approach that exploits corporate governance shocks induced by cross-listing in the U.S., we find that firms tend to engage in less tax avoidance after cross-listing. This effect is more pronounced for firms that experience significant improvements in corporate go...
Article
Empirical Existing research on sovereign wealth funds (SWFs) has largely explored how they affect target firm value, overlooking the role they play in corporate governance. This paper examines the impact of SWFs’ cross‐border equity acquisitions on targets’ corporate governance, and the role the institutional environment of SWF countries plays in s...
Article
We examine why environmental and social (E/S) performance vary across countries and firms, and evaluate the value implications. Using a sample of 33,021 firm-year observations representing 4587 firms from 43 countries over the 2003–2015 period and applying hierarchical linear modeling, we find that individualism is positively associated with firm-l...
Article
We examine the effects of geographic deregulation on banks’ cost of equity (COE) using changes in interstate bank branching laws over the post–Riegle-Neal period (1994:Q4–2016:Q4). We find strong evidence that deregulation increases banks’ COE. This is driven primarily by active acquirers, rather than those subject to increased competition from the...
Article
Using 1,584 listed banks from 64 countries during the COVID-19 pandemic, we conduct the first broad-based international study of the effect of the pandemic on bank systemic risk. We find the pandemic has increased systemic risk across countries. The effect operates through government policy response and bank default risk channels. Additional analys...
Article
We introduce this special issue on Economic Policy Uncertainty (EPU) with a focus on how EPU affects allocative efficiency. We observe that EPU affects the market value of firms in about 37% of Fama–French 30 industries, but leads to lower investments in 90% of them. Allocation decisions in a market economy rely on signals from the capital market,...
Article
Recent events, most notably the Global Financial Crisis and the COVID-19 pandemic, have made it increasingly apparent that liquidity is synonymous with corporate survival. In this paper, we explore how governments can fulfill an important need as suppliers of liquidity. Building on the financing advantage view of state ownership, we theorize how st...
Article
We provide the first international evidence on the impact of economic policy uncertainty (EPU) on dividend policy. Using data from 19 countries, we find that a high level of EPU is positively associated with dividend payout. This evidence is robust to using alternative dividend payout measures, to controlling for other sources of uncertainty, and t...
Article
Using a comprehensive set of firms from 57 countries over the 2000–2016 period, we examine the relation between institutional investor horizons and firm-level credit ratings. Controlling for firm- and country-specific factors, as well as for firm fixed effects, we find that larger long-term (short-term) institutional ownership is associated with hi...
Article
The debate over how firm stakeholder engagement is tied to preserving shareholder wealth has received growing attention in recent years, especially in the wake of the COVID-19 crisis. Against this backdrop, we examine the relation between corporate social responsibility (CSR) and stock market returns during the COVID-19 pandemic-induced market cras...
Article
We provide unique firm-level evidence of the relation between state ownership and stock liquidity. Using a broad sample of newly privatized firms (NPFs) from 53 countries over the period 1994–2014, our study identifies a non-monotonic association between state ownership and stock liquidity. The inverse U-shaped relation is consistent with trade-off...
Article
A key issue in the finance-growth nexus literature is endogeneity – economic growth may drive finance as well as finance driving growth. Some research addresses endogeneity using relatively exogenous shocks from U.S. bank geographic deregulation, often documenting favorable economic effects. We connect deregulation shocks for the first time to indi...
Article
Using a comprehensive dataset of firms from seventy-nine countries, we document the incidence, determinants, and corporate policies of zombie firms for the 2005–2016 period. Zombie firms account for roughly 10% of our observations. We find that countries with more efficient debt enforcement environments tend to have fewer zombie firms. We find no e...

Using staggered board reforms as a quasi-natural experiment and a difference-in-differences approach, this study examines the impact of corporate governance on cash holdings in 41 countries. We find that board reforms are followed by significant reductions in cash holdings. This effect is more pronounced for firms with weaker pre-reform corporate g...
Article
The last two decades have witnessed a growing interest in corporate social responsibility (CSR) worldwide by corporations, investors, policy makers, and researchers across different disciplines. This paper is part of a Special Issue devoted to CSR practices of firms in emerging market economies (EMEs). It complements prior research focusing mainly...
Article
We examine the impact of economic policy uncertainty (EPU) on bank liquidity hoarding. We create a comprehensive measure of bank liquidity hoarding that takes into account asset-, liability-, and off-balance sheet activities. Using over one million bank-quarter observations, we find that in response to EPU, banks hoard liquidity overall and through...
Article
Using a comprehensive dataset of firms from 34 countries, we study the effect of institutional investors’ investment horizons on firm valuation around the world. We find a positive relation between institutional ownership and firm value that is driven by short-horizon institutional investors. Accounting for the interaction between investors’ invest...
Article
Using data from 19 countries over the 1990–2015 period, we examine how economic policy uncertainty (EPU) affects accounting quality. We find that accounting quality, measured based on Nikolaev's (2018) model, increases during periods of high policy uncertainty. This relation is confirmed by the negative association between EPU and performance-adjus...
Article
Extant evidence is mixed on whether local investors or foreign investors are better informed. In this study, we shed light on this debate by investigating whether the information asymmetries between local and foreign institutional investors relate to state ownership of publicly listed firms. Prior research documents that state ownership is associat...
Article
Building on rational choice institutionalism theory and Williamson’s (J Econ Lit 38(3): 595–613, 2000) four-level social analysis framework, we investigate the influence of the informal institution of social trust on debt contract design in an international setting. Using a sample of non-U.S. firms that issue bonds in the U.S. debt market, we find...
Article
Using a large dataset of firms from 35 countries, we study the country-level determinants of institutional investors’ investment horizons around the world. We document that an equity investor-friendly institutional environment is more important for long-term investors, while short-term investors seem to be less concerned about the quality of the fi...
Article
We study the impact of board reforms implemented in 40 countries worldwide on corporate dividend policy. Using a difference-in-differences analysis, we find that firms pay higher dividends following the reforms. The increase in dividend payouts is more pronounced for firms with weak board governance in the pre-reform period and those in countries w...
Article
In analyzing newly collected data on the ultimate ownership structure of publicly traded firms in nine East Asian economies, we contribute to international accounting research by providing evidence on earnings management in insider-controlled firms in this region. We find that family-controlled firms engage in less (more) accrual-based (real) earni...
Article
We examine the relation between state residual ownership and bank risk-taking for privatized banks from 45 countries. Applying propensity score matching, we find that privatized banks tend to exhibit higher levels of risk-taking post-privatization than their publicly listed non-privatized counterparts. Moreover, partially privatized banks exhibit h...
Article
An extensive body of international business research examines how cross-country variations in legal institutions influence corporate finance practices. Building on this literature, as well as the literature on capital structure and product market interactions, we investigate the effect of an important dimension of legal institutions – creditor righ...
Article
Based on the social analysis framework of Williamson, we argue that national culture – especially the individualism/collectivism dimension – located in the social embeddedness level can guide behaviors and decisions in a country, including the choice of exchange rate regime. We argue that individualistic societies are more likely to choose floating...
Article
Despite the growth of Islamic banks (IBs), little is known about their liquidity creation performance and financial stability consequences relative to conventional banks (CBs). We address these issues using data from 24 countries over 2000–2014. We find IBs create more liquidity per unit of assets than CBs, primarily on the asset side of the balanc...
Article
Prior literature shows that high leverage is associated with losses in market share due to unfavorable actions by customers and competitors. Building on this literature, we investigate the effect of collectivism on the product market performance of highly leveraged firms. Using a sample of 46 countries over the 1989–2016 period, we find significant...
Article
We assess the link between corporate social responsibility (CSR) and government ownership using a unique sample of privatized firms (PFs) from 41 countries over the 2002 to 2014 period. We find that PFs have, on average, better CSR intensity than other publicly listed firms. Further tests show a nonlinear relation between residual state ownership a...
Article
We explore the stock liquidity of Islamic banks (IBs) and matching conventional banks (CBs) in emerging economies. We find that IBs have higher stock liquidity than CBs, suggesting that investors prefer IBs' stocks and neglect what they consider to be “sin stocks” (i.e., CBs' stocks), which do not conform to their religious beliefs. We also find th...

Prior research suggests that the media plays an important information intermediary role in capital markets. We investigate the role of the media in influencing firms’ engagement in corporate social responsibility (CSR) activities. Using a large sample of 4396 unique firms from 42 countries over the period 2003–2012, we find strong evidence that fir...
Article
Research on capital structure and product market interactions shows that high leverage is associated with substantial losses in market share due to unfavorable actions by customers and competitors. We examine whether corporate social responsibility (CSR) affects firms’ interactions with customers and competitors, and whether it can reduce the costs...
Article
We examine the effect of economic policy uncertainty on the relation between investment and the cost of capital. Using the news-based index developed by Baker et al. (2016) for twenty-one countries, we find that the strength of the negative relation between investment and the cost of capital decreases during times of high economic policy uncertaint...
Article
Using a unique sample of newly privatized firms from 59 countries, this article provides new evidence about the agency costs of state ownership and new insight into the corporate governance role of country-level institutions. Consistent with agency theory, we find strong and robust evidence that state ownership is positively related to corporate ca...

We examine how corporate environmental responsibility (CER) affects the cost of equity capital for manufacturing firms in 30 countries. Using several approaches to estimate firms’ ex ante equity financing costs, we find in regressions that control for firm-level characteristics as well as industry, year, and country effects that the cost of equity...
