Paper analyzes fire sales in a network of banks using VWAP and LOB pricing.
Complex contagion model explains financial fire sales through continuous asset prices.
Mathematical framework investigates fire sales amplification and stability.
This paper provides a framework for modeling financial contagion in a network subject to fire sales and price impacts, but allowing for firms to borrow to cover their shortfall as well. We consider both uncollateralized and collateralized loans. The main results of this work are providing sufficient conditions for exis…
This paper provides a framework for modeling the financial system with multiple illiquid assets when liquidation of illiquid assets is caused by failure to meet a leverage requirement. This extends the network model of Cifuentes, Shin & Ferrucci (2005) which incorporates a single asset with fire sales and capital adequ…
Study shows how capital constraints can lead to systemic crises in financial systems.
Assessing systemic risk in financial markets is of great importance but it often requires data that are unavailable or available at a very low frequency. For this reason, systemic risk assessment with partial information is potentially very useful for regulators and other stakeholders. In this paper we consider systemi…
New method identifies algo trading strategies as liquidity consumers or providers.
The scope of financial systemic risk research encompasses a wide range of interbank channels and effects, including asset correlation shocks, default contagion, illiquidity contagion, and asset fire sales. This paper introduces a financial network model that combines the default and liquidity stress mechanisms into a "…
Market stability depends on a fundamental value anchor, not price crashes.
Common asset holding by financial institutions, namely portfolio overlap, is nowadays regarded as an important channel for financial contagion with the potential to trigger fire sales and thus severe losses at the systemic level. In this paper we propose a method to assess the statistical significance of the overlap be…
The paper studies price impacts in asset liquidation markets.
In this paper we consider a mean-field model of interacting diffusions for the monetary reserves in which the reserves are subjected to a self- and cross-exciting shock. This is motivated by the financial acceleration and fire sales observed in the market. We derive a mean-field limit using a weak convergence analysis …
Study creates open-access wildfire dataset for Russia.
SVMs improve forest fire detection accuracy on challenging datasets.
FIRE extracts interpretable rules from tree ensembles.
By exploiting a bipartite network representation of the relationships between mutual funds and portfolio holdings, we propose an indicator that we derive from the analysis of the network, labelled the Average Commonality Coefficient (ACC), which measures how frequently the assets in the fund portfolio are present in th…
Dynamic risk assessment method for WUI fires improves upon static frameworks.
Despite being very effective in several classification tasks, Dynamic Ensemble Selection (DES) techniques can select classifiers that classify all samples in the region of competence as being from the same class. The Frienemy Indecision REgion DES (FIRE-DES) tackles this problem by pre-selecting classifiers that correc…
Consider an ephemeral sale-and-repurchase of a security resulting in the same position before the sale and after the repurchase. A sale-and-repurchase is a wash sale if these transactions result in a loss within calendar days. Since a portfolio is essentially the same after a wash sale, any tax advantage from …
Machine learning improves wildfire science and management, but requires expert knowledge.
Model predicts short-term Amazon rainforest fires with high accuracy.
Forest Fire Clustering discovers cell types from single-cell data.
The firefighter game problem on locally finite connected graphs was introduced by Bert Hartnell. The game on a graph can be described as follows: let be a sequence of positive integers; an initial fire starts at a finite set of vertices; at each (integer) time , vertices which are not on fire b…
Paper proposes a machine learning method to predict sale efficacy.
To investigate the actual phenomena of transport on a complex network, we analysed empirical data for an inter-firm trading network, which consists of about one million Japanese firms and the sales of these firms (a sale corresponds to the total in-flow into a node). First, we analysed the relationships between sales a…
DeFi exploits lead to reduced CP spreads, contrary to contagion hypothesis.
Study finds sales forecasters overreact to extreme news.
AI-driven sales prioritization boosts renewal bookings by 8.08%.
The paper uses transformed ANOVA to identify important fire detection variables.
The paper proposes a ML workflow for B2B sales prediction.
Model explains capital allocation and wealth distribution dynamics in a frictional economy.
SAE-FiRE extracts key financial info from long documents, improving earnings surprise predictions.
This paper improves sales forecasting on Tmall using Fourier decomposition and Tweedie distribution optimization.
Models predict fire and other emergencies in Edmonton.
Sales data in a commodity market (supermarket sales to consumers) has been analysed by studying the fluctuation spectrum and noise correlations. Three related products (ketchup, mayonnaise and curry sauce) have been analysed. Most noise in sales is caused by promotions, but here we focus on the fluctuations in baseline…
We analyze a database comprising quarterly sales of 55624 pharmaceutical products commercialized by 3939 pharmaceutical firms in the period 1992--2001. We study the probability density function (PDF) of growth in firms and product sales and find that the width of the PDF of growth decays with the sales as a power law w…
Credit and liquidity risks represent main channels of financial contagion for interbank lending markets. On one hand, banks face potential losses whenever their counterparties are under distress and thus unable to fulfill their obligations. On the other hand, solvency constraints may force banks to recover lost funding…
We analyze an exhaustive data-set of new-cars monthly sales. The set refers to 10 years of Spanish sales of more than 6500 different car model configurations and a total of 10M sold cars, from January 2007 to January 2017. We find that for those model configurations with a monthly market-share higher than 0.1% the sale…
New approach optimizes sales process for B2B businesses.
Sales forecast is an essential task in E-commerce and has a crucial impact on making informed business decisions. It can help us to manage the workforce, cash flow and resources such as optimizing the supply chain of manufacturers etc. Sales forecast is a challenging problem in that sales is affected by many factors in…
Improved sales forecasting for new products using transfer learning.
This paper proposes a vision-based fire and smoke segmentation system which use spatial, temporal and motion information to extract the desired regions from the video frames. The fusion of information is done using multiple features such as optical flow, divergence and intensity values. These features extracted from th…

Retail company uses Prophet algorithm for accurate sales forecasting.
Paper proposes decision-theoretic approach to combat wildfires.
Model shows how financial contagion spreads through complex interdependencies.
Many economic applications including optimal pricing and inventory management requires prediction of demand based on sales data and estimation of sales reaction to a price change. There is a wide range of econometric approaches which are used to correct a bias in estimates of demand parameters on censored sales data. T…
