Abstract:
The paper deals with the conception of integrated bank assets and liabilities portfolio adequate to stochastic nature of assets profitability and liabilities expenditures. Two interconnected situations are considered. Firstly, the principles of construction of an investment portfolio, adequate to stochastic nature of an investment yield arc considered. Further, the idea of consideration and optimal selection of integrated assets and liabilities portfolio is considered. These problems are solved on the basis of the authors’ idea of investment portfolio adequate for stochastic nature of investme

Abstract:
In financial markets, short sellers will be required to post margin to cover possible losses in case the prices of the risky assets go up. Only a few studies focus on the optimization and performance evaluation of portfolios in the presence of margin requirements. In this paper, we investigate the theoretical foundation of DEA (data envelopment analysis) approach to evaluate the performance of portfolios with margin requirements from a different perspective. Under the mean-variance framework, we construct the optimization model and portfolio possibility set on considering margin requirements.

Efficient portfolio is a portfolio that yields maximum expected return given a level of risk or has a minimum level of risk given a level of expected return. However, the optimal portfolios do not seem to be as efficient as intended.

Traditional methods of asset allocation (such as mean–variance optimization) are not adequate for option portfolios because the distribution of returns is non-normal and the short sample of option returns available makes it difficult to estimate their distribution. We propose a method to optimize a portfolio of European options, held to maturity, with a myopic objective function that overcomes these limitations. In an out-of-sample exercise incorporating realistic transaction costs, the portfolio strategy delivers a Sharpe ratio of 0.82 with positive skewness. This performance is mostly obtain

Abstract:
Revenue diversification and elasticity of the revenue portfolio are important characteristics of a revenue structure. Using state financial data from 2007–2012, this study identifies the different impacts of revenue diversification and revenue portfolio elasticity on the fiscal health of US states. Fiscal health is measured by a comprehensive set of indicators including measures of revenue, expenditure, operating position, and debt. We find that during an economic downturn fiscal health is improved by revenue diversification but reduced by a more elastic revenue structure. Furthermore, the ove

Purpose - The first goal of the study was to examine whether, during the years 2009– 2024, companies listed on the Warsaw Stock Exchange met the criteria of dividend aristocrats – firms that paid out non-decreasing dividends for at least five years while maintaining adequate trading liquidity. The second objective was to determine whether a long-term retirement portfolio composed of such companies yielded higher returns than the broader market (WIG), thereby enabling the accumulation and growth of capital for retirement purposes within an Individual Retirement Account (IKE).

Abstract:
Introduction. The problem of decision-making under risk and uncertainty lies in the use of adequate criteria for assessing their optimality, in particular, in an adequate risk assessment. Various functions are known that are used as risk measures. For technical systems, the probability of an accident (failure) is used, in insurance – the probability of bankruptcy, in finance – Value-at-Risk, etc. At present, the concept of a coherent risk measure (CRM), in which its basic properties are postulated, is widely recognized. The paper considers CRMs and their subset, the polyhedral CRMs (PCMRs), wh

Abstract:
Despite microfinance has been widely appreciated as an informal financial mechanism to provide financial services to the poor people in developing countries, this sector is still lacking behind in fulfilling the demand gap due to the dearth of adequate funds. Securitization opens a new horizon that overcomes the funding barriers of microfinance through which the top tier Microfinance Institutions (MFIs) can accumulate funds to enlarge their portfolio without issuing any debt or equity. This paper is a desk study that synthesizes how securitization can be used in the funding of the MFI portfoli

Initiatives to reduce energy use, source renewable electricity, and use low-carbon materials are aimed at leading by example, where governments attempt to showcase innovation through green building strategies. Greening government initiatives are promoted to reduce operating costs, improve energy system resilience, grow the “green” economy, support clean energy development, and encourage sustainable building practices.

The AI community has achieved great success in designing high-performance algorithms for hard combinatorial problems, given both considerable domain knowledge and considerable effort by human experts. Two influential methods aim to automate this process: automated algorithm configuration and portfolio-based algorithm selection. The former has the advantage of requiring virtually no domain knowledge, but produces only a single solver; the latter exploits per-instance variation, but requires a set of relatively uncorrelated candidate solvers.
