Современные математические модели влияния на цену: приложение к задаче оптимального управления портфелем на рынке, движимом заявками
This article presents an engineering approach to estimating market resiliency based on analysis of the dynamics of a liquidity index. The method provides formal criteria for defining a “liquidity shock” on the market and can be used to obtain resiliency-related statistics for further research and estimation of this liquidity aspect. The developed algorithm uses the results of a spline approximation for observational data and allows a theoretical interpretation of the results. The method was applied to real data resulting in estimation of market resiliency for the given period.
The monograph contains the results of a study of the theoretical and methodological issues of managing the liquidity of a firm. The essence of this category is determined, the types of liquidity and their financial consequences for the company are identified; various groups of methods for measuring liquidity of a company are summarized and systematized, allowing to give a comprehensive assessment of this financial characteristic, factors shaping it, ways to maintain liquidity and potential threats to reduce it. The fundamentals of liquidity management in the organization’s financial management system are investigated, providing for the need to implement the principles of interconnection and balance of strategic and short-term financial goals, risk and profitability of a company based on a two-tier liquidity management system. A system of methods, models and tools for managing liquidity is presented within the framework of the formation of the company's working capital management policy and the management of its components - stocks, receivables and payables, and cash, which determine the level of liquidity of the company. The features and priorities of managing the liquidity of transport companies are highlighted, which are based on an analysis of the specifics of their activities, capital formation, structure of current assets and sources of its financing.
