Random Forest Prediction of IPO Underpricing
The prediction of initial returns on initial public offerings (IPOs) is a complex matter. The independent variables identified in the literature mix strong and weak predictors, their explanatory power is limited, and samples include a sizable number of outliers. In this context, we suggest that random forests are a potentially powerful tool. In this paper, we benchmark this algorithm against a set of eight classic machine learning algorithms. The results of this comparison show that random forests outperform the alternatives in terms of mean and median predictive accuracy. The technique also provided the second smallest error variance among the stochastic algorithms. The experimental work also supports the potential of random forests for two practical applications: IPO pricing and IPO trading.The authors acknowledge financial support granted by the Spanish Ministry of Science under grant ENE2014-56126-C2-2-R
FAKTOR-FAKTOR YANG MENENTUKAN INITIAL RETURN PADA PERUSAHAAN IPO DI BURSA EFEK INDONESIA PERIODE 2007-2013
This study aims to analyze and provide empirical evidence related to the factors that influence the initial return on the implementation of Initial public offering (IPO). The research sample is companies that conduct IPOs in the 2007-2013 period on the Indonesia Stock Exchange. Sampling using a purposive sampling technique, while the analytical tool used logit regression. The results showed that there was a significant influence between firm size, leverage, profitability, age of the company, institutional ownership structure, underwriter reputation, auditor reputation, percentage of stock offered. The results of testing the determinant factors show that the factors included in the model can estimate underpricing in the type of service industry that conducts an Initial public offering (IPO) in the 2007-2013 period. The results also showed that only profitability, age of the company, institutional ownership structure, and underwriter reputation had a significant negative effect on underpricing. While company size had not a significant negative effect on underpricing. On the contrary leverage, auditor reputation, and the percentage of stock offered is not a significant positive effect on underpricing. This finding shows that investor's concern in investing are profitability, the length of time the company operates, the existence of an institutional ownership structure, and the existence of a reputable underwriter or agency that certifies that the company's performance is in good condition. The type of industry acts as a moderator variable which can significantly strengthen the relationship of profitability and institutional ownership structure with underpricing. Conversely, the type of industry does not provide a significant moderation effect on the effect of firm size, leverage, age of the company, the reputation of the underwriter and auditor, as well as the percentage of shares offered at an underpricing. In contrast to interest rates, it can weaken the relationship of profitability, age of the company, institutional ownership structure and underwriter reputation for underpricing. On the contrary, interest rates do not have a significant moderation effect on the effect of firm size, leverage, auditor reputation, and the percentage of shares offered on underpricing.

A comparison of artificial neural networks and the statistical methods in predicting MBA student’s academic performance
MBA has become one of the most popular and vital professional degrees internationally. The MBA program admission process’s essential task is to choose the best analysis tools to accurately predict applicants’ academic performance potential based on the evaluation criteria in making admission decisions. Prior research finds that the Graduate Management Admission Test (GMAT) and undergraduate grade point average (UGPA) are common predictors of MBA academic performance indicated by graduate grade point average (GGPA). Using a sample of 250 MBA students enrolled in a state university with AACSB accreditation from Fall 2010 to Fall 2017, we test and compare the effectiveness of artificial neural networks (ANNs) against traditional statistical methods of ordinary least squares (OLS) and logistic regression in MBA academic performance prediction. We find that ANNs generate similar predictive power as OLS regression in predicting the numerical value of GGPA. By dichotomizing GGPA into categorical variables of “successful” and “marginal,” we identify that ANNs offer the most reliable prediction based on total GMAT score and UGPA while logistic regression delivers superior performance based on other combinations of the predictors. Our findings shed light on adopting ANNs to predict academic performance potential with a strong implication in MBA admissions to select qualified applicants in a competitive environment
Essays on the New Blockchain-Based Digital Financial Market : Risks and Opportunities
This doctoral thesis consists of five original essays on the risks and opportunities of the new blockchain-based digital financial market. The purpose of this dissertation is to analyze, identify, and, if possible, predict some of the major risks in the market for blockchain-based digital assets. It analyzes how crypto-specific characteristics are associated with solvency risk, sustainability risk, seclusion risk, and sentiment risk. On top of that, it also sheds light on the opportunity side of this financial innovation.
The first essay of this dissertation specifically focuses on cryptocurrency for solvency risks. To forecast potential cryptocurrency default at an early stage, this study focuses on variables that are part of the information set of the investor 1 month at most after the start of trading for a cryptocurrency. The results of this research show that bankruptcies among cryptocurrencies are predictable. The second essay explores energy risk as a fundamental market-driving force for the pricing of cryptocurrency. Cryptocurrencies using a high-energy-consumption consensus protocol are riskier than others because their mining costs are more exposed to changes in energy price. Surprisingly, the study finds that energy consumption does not seem to play a role in pricing cryptocurrency. The third essay hypothesizes that privacy coins form a distinct submarket in the cryptocurrency market, shedding light on seclusion risk. It shows that privacy coins and non-privacy coins are two distinct asset markets within the cryptocurrency market. The fourth essay is about news media sentiment risk. It explores whether news media sentiments have an impact on Bitcoin volatility. It also differentiates financial sentiment and psychological sentiment and finds that financially optimistic investors are driving the Bitcoin market.
On the other hand, the fifth essay in this dissertation analyzes opportunities, especially the funding opportunity in the widely known category of new digital assets defined as crypto tokens. It analyzes the determinants of the success of initial coin offerings and finds that initial-coin-offering investors are largely guided by their emotions when making investment decisions. Surprisingly, regulatory framework has not yet become a priority among policymakers. Therefore, this doctoral dissertation not only facilitates future research, but also helps regulators in shaping the future of blockchain-based financial technologies.Tämä väitöskirja koostuu viidestä esseestä, jotka käsittelevät uuden lohkoketjupohjaisen digitaalisen rahoitusmarkkinan riskejä ja mahdollisuuksia. Väitöskirjan tarkoituksena on analysoida, tunnistaa ja mahdollisuuksien mukaan ennustaa joitakin lohkoketjupohjaisten digitaalisten varojen markkinoiden suurimpia riskejä. Siinä analysoidaan, miten kryptovaluuttakohtaiset ominaisuudet liittyvät vakavaraisuusriskiin, kestävyysriskiin, eristäytymisriskiin ja sentimenttiriskiin. Tämän lisäksi se valottaa myös tämän rahoitusinnovaation mahdollisuuksia.
Tämän väitöskirjan ensimmäisessä esseessä keskitytään erityisesti kryptovaluuttaan maksukyvyttömyysriskinä. Tässä tutkimuksessa keskitytään muuttujiin, jotka ovat sijoittajan saatavilla korkeintaan 1 kuukausi sen jälkeen, kun kaupankäynti kryptovaluutalla on alkanut. Tämän tutkimuksen tulokset osoittavat, että kryptovaluuttojen konkurssit ovat ennustettavissa. Toisessa esseessä tutkitaan energiariskiä markkinoita ohjaavana voimana kryptovaluutan hinnoittelussa. Kryptovaluutat, jotka käyttävät paljon energiaa kuluttavaa konsensusprotokollaa, ovat muita riskialttiimpia, koska niiden louhintakustannukset ovat alttiimpia energian hinnan muutoksille. Yllättäen tutkimuksessa todetaan, että energiankulutuksella ei näytä olevan merkitystä kryptovaluuttojen hinnoittelussa. Kolmannessa esseessä hypoteesina on, että yksityisyyskolikot muodostavat erillisen alamarkkinan kryptovaluuttamarkkinoilla, ja tutkimus tarkastelee näiden eristäytymisriskiä. Siinä osoitetaan, että yksityisyyskolikot ja ei-yksityisyyskolikot ovat kaksi erillistä omaisuuserämarkkinaa kryptovaluuttamarkkinoilla. Neljäs essee käsittelee uutismedian sentimenttiriskiä. Siinä tutkitaan, vaikuttaako uutismedian sentimentti Bitcoinin volatiliteettiin. Siinä myös erotetaan toisistaan taloudellinen sentimentti ja psykologinen sentimentti ja todetaan, että taloudellisesti optimistiset sijoittajat ohjaavat Bitcoin-markkinoita.
Väitöskirjan viidennessä esseessä analysoidaan mahdollisuuksia, erityisesti rahoitusmahdollisuuksi, liittyen laajalti tunnettuihin digitaalisiin tokeneihin. Siinä havaitaan, että näihin omaisuuseriin sijoittavat sijoittajat toimivat pitkälti tunteidensa ohjaamina sijoituspäätöksiä tehdessään. Yllättävää kyllä, sääntelykehyksestä ei ole vielä tullut poliittisten päättäjien prioriteettia. Siksi tämä väitöskirja ei ainoastaan tue tulevaa tutkimusta, vaan auttaa myös viranomaisia lohkoketjupohjaisten rahoitusteknologioiden tulevaisuuden määrittelyssä.fi=vertaisarvioitu|en=peerReviewed

spread to determine the loan agreement. This study used secondary data in the Dealscan database with 548 samples of Asia-Pacific corporates in 2006-2010. This study shows interdependencies of collateral, maturity, and loan
spread. This research reveals that the main variable which affects the loan agreement consideration is collateral
Predicting financial distress using corporate efficiency and corporate governance measures
Credit models are essential to control credit risk and accurately predicting
bankruptcy and financial distress is even more necessary after the recent global
financial crisis. Although accounting and financial information have been the main
variables in corporate credit models for decades, academics continue searching for
new attributes to model the probability of default. This thesis investigates the use of
corporate efficiency and corporate governance measures in standard statistical credit
models using cross-sectional and hazard models.
Relative efficiency as calculated by Data Envelopment Analysis (DEA) can be used
in prediction but most previous literature that has used such variables has failed to
follow the assumptions of Variable Returns to Scale and sample homogeneity and
hence the efficiency may not be correctly measured. This research has built industry
specific models to successfully incorporate DEA efficiency scores for different
industries and it is the first to decompose overall Technical Efficiency into Pure
Technical Efficiency and Scale Efficiency in the context of modelling financial
distress. It has been found that efficiency measures can improve the predictive
accuracy and Scale Efficiency is a more important measure of efficiency than others.
Furthermore, as no literature has attempted a panel analysis of DEA scores to predict
distress, this research has extended the cross sectional analysis to a survival analysis
by using Malmquist DEA and discrete hazard models. Results show that dynamic
efficiency scores calculated with reference to the global efficiency frontier have the
best discriminant power to classify distressed and non-distressed companies.
Four groups of corporate governance measures, board composition, ownership
structure, management compensation and director and manager characteristics, are
incorporated in the hazard models to predict financial distress. It has been found that
state control, institutional ownership, salaries to independent directors, the Chair’s
age, the CEO’s education, the work location of independent directors and the
concurrent position of the CEO have significant associations with the risk of
financial distress. The best predictive accuracy is made from the model of
governance measures, financial ratios and macroeconomic variables. Policy
implications are advised to the regulatory commission
The AI Revolution: Opportunities and Challenges for the Finance Sector
This report examines Artificial Intelligence (AI) in the financial sector,
outlining its potential to revolutionise the industry and identify its
challenges. It underscores the criticality of a well-rounded understanding of
AI, its capabilities, and its implications to effectively leverage its
potential while mitigating associated risks. The potential of AI potential
extends from augmenting existing operations to paving the way for novel
applications in the finance sector. The application of AI in the financial
sector is transforming the industry. Its use spans areas from customer service
enhancements, fraud detection, and risk management to credit assessments and
high-frequency trading. However, along with these benefits, AI also presents
several challenges. These include issues related to transparency,
interpretability, fairness, accountability, and trustworthiness. The use of AI
in the financial sector further raises critical questions about data privacy
and security. A further issue identified in this report is the systemic risk
that AI can introduce to the financial sector. Being prone to errors, AI can
exacerbate existing systemic risks, potentially leading to financial crises.
Regulation is crucial to harnessing the benefits of AI while mitigating its
potential risks. Despite the global recognition of this need, there remains a
lack of clear guidelines or legislation for AI use in finance. This report
discusses key principles that could guide the formation of effective AI
regulation in the financial sector, including the need for a risk-based
approach, the inclusion of ethical considerations, and the importance of
maintaining a balance between innovation and consumer protection. The report
provides recommendations for academia, the finance industry, and regulators
Crowdlending: mapping the core literature and research frontiers
[EN] Peer-to-peer (P2P) lending uses two-sided platforms to link borrowers with a crowd of lenders. Despite considerable diversity in crowdlending research, studies in this area typically focus on several common research topics, including information asymmetries, social capital, communication channels, and rating-based models. This young research field is still expanding. However, its importance has increased considerably since 2018. This rise in importance suggests that P2P lending may offer a promising new scientific research field. This paper presents a bibliometric study based on keyword co-occurrence, author and reference co-citations, and bibliographic coupling. The paper thus maps the key features of P2P lending research. Although many of the most cited papers are purely financial, some focus on behavioral finance. The trend in this field is toward innovative finance based on new technologies. The conclusions of this study provide valuable insight for researchers, managers, and policymakers to understand the current and future status of this field. The variables that affect new financial contexts and the strategies that promote technology-based financial environments must be investigated in the future.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.Ribeiro-Navarrete, S.; Piñeiro-Chousa, J.; López-Cabarcos, MÁ.; Palacios Marqués, D.
