Topics and trends in finance research: What is published,who publishes it and what gets cited?

In this study we provide a detailed examination of the subject matter of finance research and its institutional features as it has evolved over the past two decades. Drawing on novel approaches from data science, we examine the content of more than 30,000 published papers. Overall, we find a striking lack of diversity in the topics investigated and the methodological approaches used. Almost all finance research is conducted using techniques from economics and mathematics, with virtually no use made of qualitative methods or interdisciplinary approaches. Looking at the developments of the discipline over time, we document an increase in the volume of corporate finance research and a variation in the topics covered following the financial crisis, although these changes appear to be reactive and trivial rather than paradigm shifts. We also provide a cartography of research in finance and its citation-based impact by the location of authors. Leading finance research is concentrated in elite US institutions, and has a disproportionately strong citation-based impact. Compared with other business and management sub-fields, citations in finance are heavily skewed towards the top journals as the latter generate almost twice as much impact as the lower rated outlets.     

Corporate Sustainable Development: is ‘Integrated Reporting’ a Legitimation Strategy?

In the field of sustainability reporting (SR), the so‐called ‘integrated report’ (IR) is gaining momentum. In spite of its voluntary nature, a growing number of firms are adopting IR by participating in the International Integrated Reporting Council (IIRC) Pilot Programme. Stimulated by concerns on the use of SR as a legitimation strategy, the paper investigates whether the decision to adopt an IR stems from the need to repair legitimacy threats. By showing that IR adopters have significantly higher Bloomberg ESG disclosure ratings relative to non‐adopters, we reject the hypothesis of firms adopting IR as a response to a poor rating. Additionally, we show that other proxies of legitimacy pressures (size, leverage, profitability, industry) do not play a role in explaining IR adoption. Overall, our evidence suggests that corporate engagement in IR is not a matter of strategic legitimation. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment     

Sovereign credit ratings,growth volatility and the global financial crisis

Using monthly data from January 1996 to May 2010 for a panel of 76 developed and emerging economies and adopting an instrumental variable (IV) estimation technique by correcting for both heterogeneity and endogeneity with the generalized two-stage least squares (G2SLS, EC2SLS) procedure method suggested by Balestra and Varadharajan-Krishnakumar (1987) and Baltagi and Li (1995), this article provides empirical evidence that volatility of per capita GDP growth is reduced when there are positive changes in credit ratings; in other words when sovereign credit risk improves. To deal with potential simultaneity between sovereign credit ratings and output volatility, a system (3SLS) approach is undertaken, and our findings remain robust. By weakening the volatility dampening effects of ratings changes, it is found that the global financial crisis (GFC) has enhanced macroeconomic volatility. One of the channels via which sovereign rating changes affect growth volatility is the financial markets’ repricing of sovereign default risk that is reflected in sovereign credit default swap (CDS) spreads and its volatility.     

Credit rating changes and debt structure

Through examination of the relationship between rating levels and subsequent annual net debt changes, Kisgen (2006) provides support for the Credit Rationing – Capital Structure (CR-CS) hypothesis which maintains that “+” or “−” notch firms are more likely than non-notch firms to reduce net debt levels to increase the likelihood of a beneficial rating change. We add to the credit rating literature by focusing on quarterly net debt changes over the two years before and after rating changes to provide evidence that notch firms are generally not associated with lower net debt levels, greater net debt reductions, or higher probability of upgrades than non-notch firms before rating changes. Instead, notch firms with CW announcements are associated with relatively greater net debt level increases beginning three quarters before rating changes and these increases continue for firms both without and with CW announcements after the rating change. Further, in analysis of the strength of upgrades (UP) relative to downgrades (DOWN) at the time of rating change, we show that the UP/DOWN ratio is more a function of the presence of prior CreditWatch (CR) announcements than notch status. Firms without and with CW announcements exhibit UP/DOWN ratios of 0.8455 and 0.3628, respectively, with no significant differences in these ratios between notch and non-notch firms.     

Differences in online reviews caused by distribution channels

Since the use of social networks has become part of daily life for most people, many online travel agencies (OTAs) are allowing customers to log in using account credentials for social network services like Facebook (social network interface systems, SNIS) without having to create a local account on OTA sites themselves. This research explores the roles of SNIS in review generation on OTAs. For this purpose, we collected more than 174,000 online reviews for London hotels, posted from 2015 to 2016 on TripAdvisor.com. Through a series of analyses, we find that (1) concerning review generation, the portion of online reviews posted via SNIS shows no significant increase during the period; (2) reviews posted via SNIS tend to have lower ratings and be shorter than reviews posted via local accounts; (3) the channel itself, whether SNIS or a local account, does not have a direct impact on perceived review helpfulness.     

The Effect of Credit Ratings on Disclosure: Evidence from the Recalibration of Moody's Municipal Ratings

This paper examines how credit rating levels affect municipal debt issuers’ disclosure decisions. Using exogenous upgrades in credit rating levels caused by the recalibration of Moody's municipal ratings scale in 2010, we find that upgraded municipalities significantly reduce their disclosure of required continuing financial information, relative to unaffected municipalities. Consistent with a reduction in debtholders’ demand for information driving these results, the reduction in disclosure is greater when municipal bonds are held by investors who relied more on disclosure ex ante. However, we also find that the reduction in disclosure does not manifest when issuers are monitored by underwriters with greater issuer-specific expertise and when issuers are subject to direct regulatory enforcement through the receipt of federal funding. Overall, our results suggest that higher credit rating levels lower investor demand for disclosure in the municipal market, and highlight the role of underwriters and direct regulatory enforcement in maintaining disclosure levels when investor demand is low.     

Does auditor ratification matter to bondholders? Evidence from new bond issues

We investigate the relation between shareholder votes on auditor ratification and the client’s credit risk, using both parametric and nonparametric regression techniques. Using data from 2006 to 2016, we show that the proportion of shareholder disapproval for auditors heterogeneously impacts credit risk, as shown by bond spread and bond rating. The results suggest that higher shareholder disapproval of the auditor has an adverse effect on yield spread and bond ratings after controlling for firm characteristics associated with audit quality, such as auditor size and tenure.     

The characteristics of videos on demand for television programs and the determinants of their viewing patterns: Evidence from the Korean IPTV market

Korea's video-on-demand (VOD) market is led by pay TV service providers, especially internet protocol television (IPTV) service providers, and VODs for television programs (TV-VOD) represent the largest share of VOD in the country. TV-VOD is therefore of strategic importance to providers in terms of their current sales share and future growth. Focusing on the time-shift characteristics of TV-VOD and the serial complementarity of television programs, this study examines how various factors such as the characteristics of paid vs. free VOD services, and the average and variance of broadcast ratings affect VOD viewing patterns. An empirical analysis was conducted using data for TV-VODs of all television programs broadcast by major Korean broadcasters in 2015. The key findings are as follows: (1) There is an inverted-U shape relationship between broadcast ratings and TV-VOD views. This implies that there exists a positive window effect between the original broadcast and TV-VOD, with an exceptional substitution effect in segments with very high ratings. (2) Even if the average ratings are similar, there are more VOD views for programs that have a large fluctuation in ratings between episodes, mainly due to serial complementarity. (3) In terms of the distribution of VOD views over time, the initial concentration is higher in paid VOD packages and dramas, which implies that immediate decay appears for TV-VOD content because of subscriber preferences for novelty and the serial nature of drama shows. The study concludes with various implications for VOD service providers and policy makers.     

Is there valuable private information in credit ratings?

Credit rating agencies (CRAs) contend their ratings contain a quantitative assessment based on hard information, and a qualitative adjustment based on private information. We study if the qualitative portion of ratings, generated with the companies’ own private information, contains valuable information for equity investors. We generate predicted ratings based on hard information alone and form portfolios of stocks based on the difference between observed and predicted ratings. Over a sample from 1998 to 2018, we find that stock portfolios formed on the basis of private information generate 2% to 4% in annual risk-adjusted returns. We also find that companies with positive private information have better future accounting performance. Our results suggest that CRAs bring valuable information to the market and investors could benefit from it.
