The purpose of this paper is to review recent contributions to the theoretical and empirical literature on informational cascades.

This paper reviews and synthesises the existing literature, methodologies and evidence on informational cascades.

Many financial settings foster situations where informational cascades and herding are likely. Cascades remain mainly an area of experimental research, leaving the empirical evidence inconclusive. Existing measures have limitations that do not allow for a direct test of cascading behaviour. More accurate models and methods for empirical testing of informational cascades could provide more conclusive evidence on the matter.

Outlined findings have implications for designing policies and regulatory requirements, as well as for the design of collective decisions processes.

The paper reviews and critiques existing theory; it summarises the recent laboratory and empirical evidence and identifies issues for future research. Most of other theoretical work reviews informational cascades as a subsection of herding. This paper focusses on informational cascades specifically. It distinguishes between informational cascade and herding. The paper also reviews most recent empirical evidence on cascades, presents review and synthesis of the theoretical and empirical development on information cascades up to date, and reviews the model of informational cascades with model criticism.

The purpose of this paper is to examine information cascades in the context of users’ e-book reading behavior and differentiate it from alternative factors that lead to herd behavior, such as network externalities and word-of-mouth effects.

This paper constructed panel data using information concerning 226 e-books in 30 consecutive days from Sina.com’s reading channel (Book.Sina.com.cn) from October 2, 2013, to October 31, 2013 of the same year in China. A multinomial logit market-share model was employed.

E-books’ ranking has a significant impact on their market share, as predicted by informational cascades theory. Higher ranking e-books’ clicks will see a greater increase as a result of an increase in clicks ranking. Due to the information cascades effect, review volume had no impact on the market share of popular e-books. Total votes had a powerful impact on the market share of e-books, showing that once information cascade occurred, it could be enhanced by the increase in total votes. The total clicks of e-books had a significant impact on their market share, suggesting that online reading behavior would be influenced by network externalities.

As important information, the ranking or popularity of e-books should be carefully considered by online reading web sites, publishers, and authors. It is not enough for the authors and publishers of e-books to simply pay attention to the content. They should design their marketing strategies to allow network externalities and informational cascades to work for them, not against them. Online reading web sites should also focus on eliminating certain behavior, such as “brush clicks” and “brush votes,” in order to prevent an undesirable information cascade due to false information.

To the best of the knowledge, this is the first study to examine information cascades in the context of users’ e-book reading behavior. Moreover, this study can help other researchers by utilizing a large sample of daily data from one of the earliest online reading platforms in China.

The purpose of this paper is to provide a review of theory and empirical evidence on herding behavior in financial markets.

Review and discussion of the literature.

More than two decades of empirical and theoretical research have provided a significant insight on investor herding behavior.

The discussion indicates that there are still open issues and areas with inconclusive evidence, e.g. the author knows relatively little for markets other than equity markets.

The paper may need empirical methodologies to evaluate herding that address current limitations.

The paper reviews recent empirical evidence and identifies open issues for future research.

The purpose of this paper, and a companion paper (Duxbury, 2015), is to review the insights provided by experimental studies examining financial decisions and market behavior.

Focus is directed on those studies examining explicitly, or with direct implications for, the most robustly identified phenomena or stylized facts observed in behavioral finance. The themes for this first paper are theory and financial markets.

Experiments complement the findings from empirical studies in behavioral finance by avoiding some of the limitations or assumptions implicit in such studies.

The authors synthesize the valuable contribution made by experimental studies in extending the knowledge of the functioning of financial markets and the financial behavior of individuals.

The paper examines the ‘Intention to Receive the COVID-19 Vaccines’ or IRV from three perspectives: the health belief model, behavioural economics, and institutional quality.

This study provides quantitative analysis by applying Chi-squared test of contingencies, paired sample t-tests, exploratory factor analysis, and multiple linear regression (stepwise method) on the data collected from 591 respondents mainly from Malaysia.

The results show that Perceived Benefits, Perceived Barriers, Perceived Susceptibility, Herding, and Institutional Quality play roles as predictors of IRV. Perceived Benefits play the most crucial role among the predictors and Perceived Barriers is the least important predictor. People have the herding mentality after being exposed to information encouraging such behaviour.

This study reveals that the respondents changed their behaviour in different circumstances when exposed to information that incorporates the effect of herding. Herding mentality, the effectiveness of government authorities, and regulatory quality have become important factors in enriching public health policies and the effectiveness of interventions.

The purpose of this paper is to present and empirically test for the first time the hypothesis that herding in a market increases following the market's merger in an exchange group.

The hypothesis is tested empirically in EURONEXT's four European equity markets (Belgium, France, the Netherlands and Portugal) on the premise of the Hwang and Salmon (2004) measure which allows us insight into the significance, structure and evolution of market herding. Tests are conducted for each market for the period prior to and after its merger into EURONEXT, controlling for a series of variables (market conditions, common risk factors, size) to gauge the robustness of the findings.

Results indicate that, with the exception of Portugal, herding grows in significance, yet declines in momentum post-merger. The authors ascribe the findings to EURONEXT's enhanced transparency (which makes it easier for investors to observe their peers’ trades, thus allowing them to infer and free-ride on their information) and its fast-moving informational dynamics that render herding movements shorter-lived. These results are robust when controlling for various market states and common risk factors, with deviations being observed when controlling for size and market volatility.

The study presents results for the first time on the impact of exchange mergers on herd behavior. The authors believe these to constitute useful stimulus for further research on the issue and bear important implications for regulators/policymakers in view of the ongoing proliferation of exchange mergers that has been underway since the 1990s.

When purchasing digital content (DC), consumers are typically influenced by various information sources on the website. Prior research has mostly focused on the individual effect of the information sources on the DC choice. To fill the gap in the previous studies, this research includes three main effects: information cascades, recommendations and word of mouth. In particular, the purpose of this paper is to focus on the interaction effect of information cascades and recommendations on the number of software downloads.

The authors use the panel generalized least squares estimation to test the hypotheses by using a panel data set of 2,000 pieces of software at download.cnet.com over a month-long period. Product ranking and recommendation status are used as key independent variables to capture the effects of information cascades and recommendations, respectively.

One of this study’s findings is that information cascades positively interact with recommendations to influence the number of software downloads. The authors also show that the impact of information cascades on the number of software downloads is greater than one of the recommendations from a distributor does.

Information cascades and recommendations have been considered as the primary effects for online product choices. However, these two effects typically are not considered together in one research. As previous studies have mainly focused on each effect, respectively, the authors believe that this study may fill the gap by examining how these effects are interacted to one other to influence customers’ choices. The authors also show that the impact of information cascades on the number of software downloads is greater than one of the recommendations from a system does.

The study aims to measure the subscription level and examine the determinants of oversubscription of small and medium enterprise (SME) initial public offerings (IPOs) in India.

The study employs cross sectional data to analyze 403 SME IPOs issued from Feb 2012 to May 2018 and listed on Bombay Stock Exchange's small and medium enterprise (BSE SME) platform and National Stock Exchange (NSE) EMERGE to investigate the determinants of oversubscription of SME IPOs. Hence, the study makes use of ordinary least square regression and quantile regression to test the hypotheses formulated for the determinants of oversubscription.

The main findings unveil that while issue price, pricing mechanism, listing delay negatively influence oversubscription; firm size, underwriter reputation, hot market and underpricing have been divulged to positively influence oversubscription. However, issue size emerged out to be significant in quantile regression at 25th, 50th and 75th quantiles.

The present study is confined to limited number of variables in understanding the factors impacting oversubscription. Future studies could include macroeconomic variables like gross domestic product (GDP), inflation rate, industry specific variable, i.e. technology/nontechnology industry, financial/nonfinancial industry for better understanding. Cross country analysis is suggested in future studies to validate the findings of current study. Future studies are advised to conduct the study examining the factors affecting oversubscription in light of COVID-19 pandemic.

The findings of the present study offer implications to academicians, investors, investment advisors and regulators. It provides useful insights to researchers by listing the factors that contribute to variation in subscription levels in emerging economy like India thereby, paving the way for future researches in SME IPOs in countries with different institutional settings. For investors, the study provides additional and novel information useful for IPO valuation and informed investment decisions. In addition, the findings put investment advisors in better place to guide potential investors regarding investment in good quality SME stocks (i.e. highly subscribed stocks) in more informative manner. Last but not the least, as this study would assist the regulators in handling future IPOs in a way that augments the chances of success of SME IPOs.

This study is a novel contribution in widening the IPO literature by examining the relationship between pre-IPO firm actions like issue price, pricing mechanism, issue size, firm size, listing delay, underwriter reputation, hot market, underpricing and oversubscription in unexplored settings of Indian SME IPOs.

The purpose of this paper is to investigate the changes in initial public offering (IPO) underpricing and short‐run performance following a regulatory reform (No. 54 [2002] China Securities Regulatory Commission (CSRC)) of the method of allocating IPO shares in China.

On 20 May 2002, the CSRC announced that IPO subscription and allotment would be based on the market value of investors' tradable shareholdings. Before the regulatory change, this was determined by the amount of funds used for subscription. The reform was intended to increase participation by both smaller and institutional investors. Based on a sample of 209 IPOs in the Shanghai A‐share market during the period 2001‐2003, the paper employs an event study methodology to examine the impact of this IPO regulatory reform.

The paper finds that the overall (pre‐ and post‐reform) average abnormal initial return of 116.94 per cent is lower than in earlier studies of Chinese IPOs but higher than in other markets. Post‐reform underpricing decreases by 42.27 per cent compared to pre‐reform levels. In the post‐listing aftermarket a pre‐reform upward trend of cumulative abnormal returns was reversed to become downward post‐reform. The results suggest that the regulatory change has encouraged well‐informed investors, consistent with Information Cascades and Bandwagon hypotheses. It also appears that the reform improved market efficiency and secondary market liquidity.

The findings shed light on the relationship between IPO costs, IPO pricing, market liquidity and market microstructure. They also have important implications for issuers, underwriters and in particular for policy markers.

Since May 2016, small firms have been able to issue debt and equity securities in accordance with the Securities and Exchange Commission's “Regulation Crowdfunding”. This regulation provides unsophisticated investors a chance to participate in the securities markets, and it gives small businesses an opportunity to raise funds. This paper investigates the determinants of crowdfunding success, security design in a crowdfunding setting, the amount of crowdfunding campaign proceeds and campaign duration.

The sample used in this study is based on 750 completed securities crowdfunding offerings that were launched between May 2016 and May 2018. The data on crowdfunding issues were webscraped from Form C filings available through SEC EDGAR filing system. Additional data were hand-collected from a variety of platforms that list and aggregate crowdfunding offerings.

We show that relatively larger and more profitable companies have a better chance to achieve crowdfunding success. We find that the issuance of equity results in a lower probability of success compared to issuing debt. In addition, the issuance of equity is negatively correlated with the amount of proceeds from a crowdfunding campaign. A novel finding is that a choice of a funding instrument has a negligible impact on the amount of proceeds. This finding, combined with reduced probability of success for equity issuers, can be interpreted as a signal to rely more on debt and convertibles when designing crowdfunding campaigns.

Organized under “Regulation Crowdfunding,” the US securities-based crowdfunding market has been operating for several years. Relative to other securities markets it is still considered to be in its infancy. Given a relatively small data sample, the results have to be interpreted with caution.

The paper shows that small businesses and unsophisticated investors can benefit from securities-based crowdfunding, which is subject to oversight of the Securities and Exchange Commission (SEC). Although the mission of the regulator is to protect investors, the SEC took on a rather relaxed approach in regulating types of instruments used in crowdfunding. Our paper shows that equities, including “Simple Agreements For Future Equity” (SAFEs) might not be the best choice for crowdfunding success. This sentiment is mirrored in law literature which considers securities known as SAFEs more suitable for venture capital campaigns rather than for crowdfunding.

The paper adds value to the novel field of securities-based crowdfunding by testing several hypotheses on the crowdfunding success, the amount of proceeds and campaign duration.
