General government revenue in the system of fiscal regulation

The paper investigates discretionary budget expenditure and determines its role in the system of regulation of country’s socio-economic development. In a very difficult political and socio-economic situation, Ukraine faces an urgent need to finda balance between the amount of functions performed by the state and the level of their financial support. The analysis of the State Budget of Ukraine expenditure according to the functional classification in 2014–2017 has been carried out. In particular, the discretionary budget expenditures (on state functions, economic activity, defense budget expenditures, budget expenditure on public order, security and judiciary; environmental protection, housing and utilities) are carefully analyzed. The purpose of the article is to study trends in financing discretionary budget expenditure and determine their impact on the socio-economic development of a country. Discretionary budget expenditures are the study object. It is determined that socio-economic development of a country requires government to apply progressive forms, methods and principles of expenditure management between the budget system levels. This need is due to the objective necessity to achieve sustainable development of economy and population welfare. The main problems that reduce budget discretionary expenditure effectiveness in the current conditions are investigated and the main directions to improve their financing are offered. The obtained results indicate the need to revise the funding of discretionary budget expenditures depending on the state policy priorities.

The stock market represents complex systems where multiple agents interact. The complexity of the environment in the financial markets in general has encouraged the use of modeling by multi-agent platforms and particularly in the case of the stock market.
In this paper, an agent-based simulation model is proposed to study the behavior of the volume of market transactions. The model is based on the case of a single asset and three types of investor agents. Each investor can be a zero intelligent trader, fundamentalist trader or traders using historical information in the decision making process. The goal of the study is to simulate the behavior of a stock market according to the different considered endogenous and exogenous variables.

Tourism is the main service industry significantly developing in the world. It is recognized as the critical factor in economic improvement in various countries. Saudi Arabia is one of the oldest and most famous spots for pilgrimage tourism due to its Islamic heritage. The study analyzes data available on the websites of the Saudi government to specify the contribution of travel and tourism revenue to the economy and its trend, occupancy of residential, and transportation capacity. A tourism satisfaction questionnaire was administered online to get the responses of Saudi nationals and residents related to tourism infrastructure, facilities, and other tourism services in Saudi Arabia. Ranks and percentage analysis were applied to get the relational satisfaction of tourists. Index numbers, ratios, percentages, and coefficient of variations were applied to get the trend, yearly fluctuations, variations, weights, and contribution of tourism avenues. There is a positive but low degree correlation between tourism revenue and the GDP of Saudi Arabia for the period from 2010 to 2018. The results indicate either negative or negligibly positive revenue growth of the accommodation/hotel services, food services, and air transportation. Two-thirds of tourists are either strongly satisfied or satisfied with essential and other tourism services and facilities in Saudi Arabia. Apart from tourist satisfaction, the Saudi government may consider a variety of services as per the economic level of the targeted tourists, and softening of visiting visa procedures and fees to enhance tourism revenue of major contributors for the positive and progressive development to the economy.
