Proposes a more robust rating scale for banks.
We consider that the price of a firm follows a non linear stochastic delay differential equation. We also assume that any claim value whose value depends on firm value and time follows a non linear stochastic delay differential equation. Using self-financed strategy and replication we are able to derive a Random Partia…
In this paper, which is the third installment of the author's trilogy on margin loan pricing, we analyze monthly observations of the U.S. broker call money rate, which is the interest rate at which stock brokers can borrow to fund their margin loans to retail clients. We describe the basic features and mean-rev…
iConViz helps banks manage default contagion risk in networked loans.
This study uses TDA to map corporate failure, revealing distinct regions of risk.
Bitcoin treasury companies leverage stock to grow, using advanced statistical methods.
In this paper we formulate a corporate bond (CB) pricing model for deriving the term structure of default probabilities (TSDP) and the recovery rate (RR) for each pair of industry factor and credit rating grade, and these derived TSDP and RR are regarded as what investors imply in forming CB prices in the market at eac…
The existence of asymmetric information has always been a major concern for financial institutions. Financial intermediaries such as commercial banks need to study the quality of potential borrowers in order to make their decision on corporate loans. Classical methods model the default probability by financial ratios u…
The importance of adequately modeling credit risk has once again been highlighted in the recent financial crisis. Defaults tend to cluster around times of economic stress due to poor macro-economic conditions, {\em but also} by directly triggering each other through contagion. Although credit default swaps have radical…
XGBoost predicts bank loan defaults with improved accuracy.
In this paper we first introduce two new financial products: stock loan and capped stock loan. Then we develop a pure variational inequality method to establish explicitly the values of these stock loans. Finally, we work out ranges of fair values of parameters associated with the loans.
The study examines how board diversity and CSR committee composition affect corporate governance and financial performance.
Examines how extending home loan durations affects French households financially.
Two models predict net loan losses using Bayesian and frequentist regression.
Private credit markets have expanded significantly, offering unique lending technology to private equity firms.
Current auto loans converge to super-prime credit despite remaining underwater.
We use bank-level balance sheet data from 2005 to 2010 to study interactions within the banking system of five emerging countries: Argentina, Brazil, Mexico, South Africa, and Taiwan. For each country we construct a financial network based on the leverage ratio dependence between each pair of banks, and find results th…
An integrated and extendable approach for stress-testing loan portfolios
CCR-CNN uses CNN to predict corporate credit ratings from financial data.
A stock loan is a loan, secured by a stock, which gives the borrower the right to redeem the stock at any time before or on the loan maturity. The way of dividends distribution has a significant effect on the pricing of the stock loan and the optimal redeeming strategy adopted by the borrower. We present the pricing mo…
Study shows corporate governance improves stock liquidity with noise traders' participation.
Extends ASRF model for green and brown loans, accounting for systematic and idiosyncratic risks.
Paper solves stock loan pricing with finite maturity using integral equations.
Logistic Regression and Support Vector Machine algorithms, together with Linear and Non-Linear Deep Neural Networks, are applied to lending data in order to replicate lender acceptance of loans and predict the likelihood of default of issued loans. A two phase model is proposed; the first phase predicts loan rejection,…
Derivatives impact U.S. banking sector's systemic risk, but loan and leverage ratios are more significant.
We derive a "semi-analytic" solution for a stock loan in which the lender forces liquidation when the loan-to-collateral ratio drops beneath a certain threshold. We use this to study the sensitivity of the contract to model parameters.
Corporate venture capital is in the midst of a renaissance. The end of 2015 marked all-time highs both in the number of corporate firms participating in VC deals and in the amount of capital being deployed by corporate VCs. This paper explores, rather than defines, how these firms find success in the wake of this sudde…
Develops simple approximations for credit risk estimation.
Optimal student loan repayment strategies vary based on loan size.
This paper works out fair values of stock loan model with automatic termination clause, cap and margin. This stock loan is treated as a generalized perpetual American option with possibly negative interest rate and some constraints. Since it helps a bank to control the risk, the banks charge less service fees compared …
Framework integrates financial and annual report data for better corporate credit ratings.
Paper calculates loan loss after default using Bayesian model.
A stock loan is a contract whereby a stockholder uses shares as collateral to borrow money from a bank or financial institution. In Xia and Zhou (2007), this contract is modeled as a perpetual American option with a time varying strike and analyzed in detail within a risk--neutral framework. In this paper, we extend th…
Kiva is an online non-profit crowdsouring microfinance platform that raises funds for the poor in the third world. The borrowers on Kiva are small business owners and individuals in urgent need of money. To raise funds as fast as possible, they have the option to form groups and post loan requests in the name of their …
Study finds it hard to establish common factor pricing in corporate bonds.
CAI automates extraction and validation of corporate GHG emission metrics.
Study finds corporate boards with women appoint more women, leading to better profitability.
In 1979 following a decade of hyperinflation, Iceland introduced Verðtryggð lán, negatively amortised, index-linked loans whose outstanding principal is increased by the rate of the consumer price inflation index(CPI). The loans were part of a general government policy which used indexation to the CPI to address the ec…
Flashot visualizes Flash Loan attacks in DeFi systems.
Paper uses BERT to assess P2P borrowers' credit risk from loan descriptions.
The study examines how limited liability and haircut affect a bank's loan portfolio's liquidity risk.
Zero-Liquidation loans protect ETH borrowers from liquidation risks.
Retail investors set interest rates for P2P loans based on borrower characteristics.
Study examines UK firms' financial performance linked to corporate governance.
The authors examine the concept of probability of default for asset-backed loans. In contrast to unsecured loans it is shown that probability of default can be defined as either a measure of the likelihood of the borrower failing to make required payments, or as the likelihood of an insufficiency of collateral value on…
Online Peer to Peer Lending (P2PL) systems connect lenders and borrowers directly, thereby making it convenient to borrow and lend money without intermediaries such as banks. Many recommendation systems have been developed for lenders to achieve higher interest rates and avoid defaulting loans. However, there has not b…
Quantum mechanics applied to credit loans for better repayment schedules.
Credit Scores are ubiquitous and instrumental for loan providers and regulators. In this paper we showcase how micro-loan credit system can be developed in real setting. We show what challenges arise and discuss solutions. Particularly, we are concerned about model interpretability and data quality. In the final sectio…
