This study is designed to develop the tool for risk assessment under the integrated approach. Analyzing risk several problems are encountered: the first one arises at the farm level – assessment of risk in the whole-farm context rather than in a partial context, i.e. an integrated risk assessment tool is necessary. The second problem is related to the dynamic aspect when determining how the risk changes over time and what the main drivers of these changes are. All these problems are solved in the presented research, creating an integrated risk assessment index (IRAI) and testing it in Lithuanian family farms. This index assesses four types of risk: economic, financial, production, and political. The research methodology is developed to make sure that the data collected on the IRAI behavior is as diverse as possible. A model of IRAI variation by farm size illustrating risk evolution at the Lithuanian farms and, at the same time, enabling visual diversification of the dependence of integrated risk on farm size is developed. Hierarchical cluster analysis is applied for identification of the integrated risk evolution models. Assessment of the interaction between the IRAIand output and input using nonparametric Kruskal-Wallis testis used to find out whether the type of integrated risk is based on differential logic. IRAI was tested using official statistical data of 1300 family farms collected in 2004–2013 for institutional purposes. The testing revealed that the designed IRAI allows identifying types of farms by their risk evolvement profiles and the key risk (s) acting on the farm in the historical period. Four meaningful clusters representing the changing pattern of the risk are identified during the testing of IRAI: increasing risk farms; reducing risk farms; relatively constant risk farms; varying risk farms. IRAI can be applied both for macro analysis (at a national, EU or other levels) and microanalysis (at the level of a single farm).

The selection of project delivery systems is a complex decision-making process, which is also a critical task for owners. The complexity problem arises from the uncertainty of decision making environment and construction project itself. Pythagorean fuzzy sets (PFS), as an extension from intuitionistic fuzzy sets (IFSs) to deal with uncertainty information, has attracted more scholars’ attention in the decision making area. In this paper, we develop three similarity measures (i.e., 1-type PFSs similarity measure, 2-type PFSs weighted similarity measure, 3-type PFSs weighted similarity measure), and investigate their properties. Then an improved TOPSIS decision making framework is further established with PFSs information, in which the proposed similarity measures are employed to measure the similarity degree between each alternative and negative ideal solution and positive ideal solution. Finally, a case study of the selection of project delivery systems is presented to proof the performance of the proposed decision making method.

Worker remittances are the main source of financial flow to any economy. This study intended to scrutinize the effect of remittance inflow on Pakistan’s economy over the period 1976- 2016 by employing autoregressive distributed lag (ARDL) technique; because this method has been recently developed and has different advantages as compared to time series methods. ARDL method was applied to scrutinize the long run and the short run effect of worker remittances on Pakistan’s economy. This study concluded that Pakistan’s economy is positively affected by remittance inflow, foreign direct investment and the gross domestic saving in the long run, while Pakistan’s economy negatively affected by inflation and consumption in the long run. Remittances received from immigrant support economic growth in Pakistan because remittances inflow is mostly utilized for investment purpose. To further improve the economic development of Pakistan’s economy, it is suggested that policy maker in Pakistan encourage and motivate migrants to send remittances through proper channels to Pakistan, so that these inflows of remittances be used in such profitable investments that help to improve economic growth.

The research subject is the investment environment problems analysis and evaluation of the developing countries, namely, the Republic of Serbia, Croatia, Slovenia, and Hungary. The analysis was carried out by testing and implementation of the Value-at-Risk models, i.e, the historical simulation (HS VaR), the delta-normal VaR (D VaR) and the extreme value theory model (EVT), with the confidence level of 95% for 100, 200 and 300 days, in the period from 2012 to 2016. The basic hypothesis of the research is that there is a relation between the successful application of the historical simulation (HS VaR), the delta-normal VaR (D VaR) and the extreme value theory model (EVT) and the conditions and opportunities of the investment environment of the developing countries. The research results provide a concrete knowledge of the conditions and circumstances of the investment environment in the observed markets, with a simultaneous performance assessment of the tested VaR models.

To manage and cope with significant, radical changes of business processes and activities in the context of Industry 4, it is necessary for organizations to have a rapid reactive ability. This requirement may be fulfilled by performance measurement system (PMS) which should be aligned with and could reflect the current digitalization and innovative trends. According to this PMS should be developed due to changes in technology, business environment and organizational processes. But the main uncertainty here is to understand what are the main changes and development trends of PMS needed in the context of Industry 4?To solve this problem, the research presents how PMS can be developed facing industrial revolution using qualitative research method - case study with multiple sources of evidence from semi-structured interviews and documents analysis. According to research results a comprehensive framework for changes in PMS due to the alterations of Industry 4 was developed. Case study results show that technological developments and digitalization processes lead to a more intensive use of predictive methods in planning processes as well as faster control and decision making processes. The main contribution of this paper is to highlight the scientific literature of performance measurement by providing a comprehensive view of developments in PMS in the context of Industry 4. From a practical perspective, the study provides specific practical insights in order to support the reaction processes within organization.

The importance of corporate sustainability reporting continues to grow. This growth is rooted in numerous contingent factors and scientific questions regarding the key contingent variables arise. Knowledge related to these issues is important both for academic and practical purposes. Although sustainability reporting and sustainability management are not identical activities, they are strongly interconnected and communication, per se, is of great importance for the sustainability of companies. In the Czech Republic, and especially in the Slovak Republic, there is a lack of up-to-date empirical research into the extent of sustainability reporting and our article addresses this research gap. The primary concern is the investigation of the association between the amount and structure of disclosure and its determinants. Scientific methods of content analysis, ratio analysis, and statistical data analysis including regression analysis are applied. Few companies report on environmental and social issues in a comprehensive way. The structure and amount of reporting is similar in the countries analyzed. Company size positively impacts the relative share of both environmental and social disclosure in the total disclosure. Company affiliation to a high-profile industry positively impacts the relative share of environmental disclosure in the total disclosure, as well as the total amount of environmental disclosure. Total amount of disclosure positively impacts the absolute amount of economic, environmental and social disclosure. Reporting, in accordance with the IFRS, positively impacts the relative share of social disclosure in the total disclosure.

Information communication technologies bring the revolution into all business sectors, and transportation sector is not an exception. Ticketing system has changed from traditional to intelligent, which provides information and service to the consumer. In developed countries such systems are implemented and operate successfully, while in the developing countries electronic ticketing and other similar innovative solutions face specific challenges. These challenges are related to information era and changes in consumer behaviour, caused by the development of information and communication technologies. In these new conditions the motives of consumers to choose electronic ticketing has become an extremely important factor of success. Lack of integrity of consumer behaviour and technology acceptance (electronic ticketing in particular) was identified in previous scientific research, especially taking into consideration recent conditions of developing countries. The aim of this article is to evaluate the consumers’ behaviour and acceptance of intelligent systems, such as electronic ticketing, in order to identify factors, influencing and encouraging the customers to use electronic ticketing systems. In this study extended technology acceptance model with trust element was used to measure the consumer behaviour. The sample for this research has been taken from China and Pakistan populations and consists of 432 participants from both countries.

Financial pricing and prediction of stock markets is a specific and relatively narrow field, which have been mainly explored by mathematicians, economists and financial engineers. Prediction with the purpose of making profits in a martingale domain is a hard task. Pairs trading, a market neutral arbitrage strategy, attempts to resolve the drawback of unpredictability and yield market independent returns using relative pricing idea. If two securities have similar characteristics, so should their prices. Deviation from the acceptable similarity range in prices is considered an anomaly, and whenever noticed, trading is executed assuming the anomaly will correct itself.This work proposes a fuzzy inference model for the market-neutral pairs trading strategy. Fuzzy logic lets mimicking human decision-making in a complex trading environment and taking advantage of arbitrage opportunities that the crisp models may miss to acquire for the trade decision-making. Spread between two co-integrated stocks and volatility of the spread is used as decision-making inputs. Spread is a measure of the distance between two stocks and volatility is an indicator of how soon the spread would disappear. We conclude that fuzzy engine contributes to the profitability and efficiency of pairs trading type of strategies.
