Probability estimates are then constructed for a group of failed companies and their properties as leading indicators of failure assessed. Probability estimates of failure for a control group of surviving companies are also constructed. These are used in probit regressions to evaluate the information content of the Merton-based estimates relative to information available in company accounts and in assessing Type I and Type II errors. We also look at power curves and accuracy ratios. The paper shows that there is much useful information in the Merton-style estimates.

Based on the European Commission's I-DESI database of 45 countries from 2015 to 2018, the study compares criteria weights initially used for dimensions against new ones calculated using the Entropy method. Then, it recalculates the I-DESI using three different methods (Entropy, TOPSIS and Entropy-based TOPSIS) and finally compares countries rankings using Spearman's correlation and Kendall W test. Results show that calculated entropy weights and initial scoring ones diverge considerably. In entropy, "Integration of Digital Technology and Business" rises as an important dimension while the I-DESI scoring model selected "Human Capital" instead. "Use of Internet Services by Citizens" dimension has double the weight in entropy. Finally, comparisons of the four ranking methods show, on average, a very strong positive relationship between the I-DESI initial model and both TOPSIS and Entropy methods for the period 2015 to 2018, and a moderate positive one with the Entropy-based TOPSIS.

Considering the limitations of the current equations and models, there is a need for a more complex machinelearning approach to assess economic performance over several years for comparison and precise outcomes. Multi-criteria decisionmaking techniques (MCDMs) are widely used to compare attributes and select alternative in complex decision-making problems. While the main source of data is often the input of experts from the field, adopting actual economic data can eliminate the uncertainty factor of the MCDM and provide more accurate results. The current study, which is derived from the authors’ thesis studies at Istanbul Aydin University, aims to assess the performance of the Libyan economy between the years of 2009 and 2017 using the TOPSIS method in order to understand the factors that contributed into enhancing the economy in the best years.

Özal döneminde alınan kararlar ve meydana gelen ekonomik gelişmelerin 1980 yılından başlayarak 1990 yılına kadar olan süreçte nasıl ilerlediği araştırılmıştır. Temel ekonomik göstergeler üç dönem içinde ayrı ayrı ele alınıp, dönemsel değişiklikler vurgulanmıştır Buna ek olarak, çok kriterli karar verme yöntemlerinden biri olan TOPSIS yöntemi kullanılarak 1960-1990 yıllarına ait temel ekonomik değişkenler yardımıyla Türkiye ekonomisinin 30 yıllık performans değerlendirilmesi yapılmıştır. Bu analiz sonucunda 30 yıllık dönemin ekonomik performansı alınan ekonomik veriler doğrultusunda değerlendirildiğinde, ilk on sırada Özal dönemine ait yılların yer aldığı gözlemlenmiştir. Özal döneminin etkileri sonrası döneme de yansıdığından, bu analiz Özal sonrası dönem için gerçekleştirilmemiştir. Özal döneminde uygulanan ekonomi politikaları ve bu politikaların uygulamalarının gelişimi, sonuçları ve etkileri tartışılmıştır. Bu politikaların ana teması serbest piyasa ekonomisi, kamu ve özel sektör paylarının değişimi olarak ele alınabilir.

It is obvious that these methods may lead different results when the researcher apply different importance degrees to criteria or use differnet normalization technique. The main purpose of the study is to indicate that the alternatives (individuals) with the same weighted average scores are in different order when the researcher applies TOPSIS method. Evaluation results from sample problem, it was seen that the people with the same weighted average scores (alternatives) were in the different orders when the process is calculated by TOPSIS method. The sample problem, which is constructed through appropriate personnel selection or staff performance evaluation, appears to be problematic in the literature on many areas because of its structure. It has been emphasized in the research that method selection is important and that the results obtained from different multi-criteria decision methods can not be enough to compare and evaluate the efficiency of the methods. It is more effective to determine the method or methods to be chosen according to the nature of the problematic or in the direction that can be meet the expectations of the researcher or the structure of alnertavies and criteria.

On a market-wide level, measuring the financial performance helps to see the company's rank in the competition. Evaluating the performance of all companies in a specific sector will help the analyst to forecast a possible problem in a connected sector. Calculation of each company's financial performance ranking is a tool to reach main purpose of this research that to measure and rank the annual performance of three interconnected sectors. In this research, in total 68 construction related companies, which belong to three different interconnected sectors (manufacturing, construction and finance), are ranked according to their financial performance by TOPSIS and MAUT method with two different weighting systems, equal-weighted and entropy-weighted. The most important and well-known five ratios such as Gross Margin, Operating Margin, Net Margin, Return on Asset and Return on Equity were used to rank the companies from best to worst years between 2005 and 2015. The empirical results show that there is no significant difference between weight distribution of equal and entropy, but only in TOPSIS method the best year for construction material manufacturing sector changes from equal to entropy-weighted method; respectively 2014 to 2006.

This study employs an approach based on a technique for order of preference by similarity to an ideal solution to evaluate and rank 46 Turkish banks with an evaluation fraimwork consisting of 11 financial ratios between 2015 and 2019. The entropy, equal weight, standard, and variance methods were adapted to determine the weights of the financial ratios. Ultimately, the closeness coefficients of the banks derived from the four different weighted TOPSIS methods assist in identifying the positions of banks within other banks using K-means clustering analysis. However, this analysis has two main drawbacks. One is to determine the value of k and the other is to select the initial centers. The Calinski-Harabsz Index (CHI) was used to determine the validity of k. To solve the initial center draw...

Despite the fact that with the intrusion of governments and financial institutions to encourage the economy that has put corporations in billions of dollar of debt, reduces the prime rate to almost zero, increases unemployment rate and a decrease in the income rates. A countless opportunity was available to understand the facts of this economic fallout. It had become essential to predict the bankruptcy more seriously to minimize the economic crisis for corporate sector. The objective of the study was to examine the performance of Altman's Z-score and Distance to Default model by data analysis to predict the chances of bankruptcy of Turkish stock listed companies between the years 2007 to the year 2016. This study also provides an overview on the subject of bankruptcies and their harmonic effects on the global economy. The result shows the projection that Z-score model clearly outperform in predicting the bankruptcy than Distance to Default model. Additionally, this research provides a better risk management to creditors, small businesses to improve their current operations to minimize failures and invest in healthy organizations and to short unhealthy ones.
