AbstractAlthough the low level of tuition fees and the absence of other access barriers, Italy is characterized by low educational attainments at the university level. This work models the choice of young Italians to attend university or leave education and enter the labor market, by making use of an agent-based model that reproduces the Italian higher education and policy system. The aim is to analyze the determinants behind university enrollment decisions possibly causing the low level of attainment and explore three alternative scenarios that propose the expansion of financial support and the increase in the average income gap between skilled and unskilled individuals. The model implies that the individual preference to enroll at university depends upon (i) economic motivations, represented by the expectations on future income, which are formed through interaction within individuals’ social network; (ii) influence from peers; (iii) effort of obtaining a university degree. Results show that the model can reproduce observable features of the Italian system, and highlights low income levels and the following full resort to regional scholarships. Experimented scenarios show that policies expanding financial support to education are ineffective, while an increase in the gap between average income of skilled and unskilled workers leads to an increase in enrollment in university, signaling that labor market policies may be more effective than educational policies in raising the number of students in higher education.

institution is one of the highest institutions that have the task of providing the development needs of the community of specialists in various fields, in addition to being the centers of scientific research and applied to ensure economic and social progress It enriches decision makers with expertise and skills and thus controls political performance. In any society, the university can not play its full role in social change without interaction between the individual on the one hand and the social environment on the other, Social and interdependent Ah syndrome change, they strengthen the skills, and enrich the spirit of innovation of the individual, and raise the level of social progress. It helps to improve the conditions of the poor segments of the population and facilitates the employment opportunities of the individuals imposed by the society as they meet the needs of the individual and society of different professions, thus providing an opportunity for production and thus have a positive impact on the standard of living to achieve the well-being of the individual and the citizen. The interest reflected on the progress, such as Germany, which was interested in it became one of the main reasons that led to the rise of Germany from the ruins of the Second World War as well as the State of Malaysia, which moved from developing countries to the second world countries by changing the plan Colleges and institutes of universities. In 2020, Malaysia will be among the developed countries. In these countries, higher education, vocational training and training are viewed as a basis for life supplementation and are seen as a major means of improving and upgrading society. If we are to explore the dimensions of education in the 21st century, one of the pillars of education is learning for action, Usually involves the acquisition of skills and the linking of knowledge to practice as an essential part of the training and rehabilitation of the individual for practical life. Hence, such new trends in linking educational preparation to work have been imposed by the labor market and the working life in its new forms. Production and service facilities, The advanced, assumed graduates who can be employed and absorbed can contribute to the development of competitiveness, to provide innovations and creations to achieve the competitive advantage of the enterprise, and to improve production and productivity based primarily on the acquisition and application of knowledge. Gamerdinger reveals that the new technology does not accelerate the possibilities for sound economic policies and increasing global trade, and this requires strategies to develop work related to the development of human performance, and in order to face the state of chronic unemployment globally, education policies are headed towards the so-called reverse conversion as many graduates of specializations Literaries choose vocational and technical education in technical and community colleges. Unemployment in the Arab world carries certain characteristics that must be taken into account when developing the solutions available to them. The most important of these characteristics are: Unemployment is a youth phenomenon. Weak professional experience available to the unemployed. Lack of targeted planning for the labor market. The large gap between the outputs of higher education for youth and the requirements of the labor market. The most important recommendations aimed at enhancing the role of universities in Iraq are: 1 - the operation of labor graduates of technical and technical institutes in the industrial field in order to promote them and eliminate unemployment and increase the hard currency as an important category of Iraqi society, which contributes actively to the renaissance of the country. Linking the Ministry of Industry and Commerce with the Ministry of Higher Education and Scientific Research to be managed by the Minister of Education alone. The Ministry is keen on the funds of the Iraqi people and contributes to the development of the industrial and commercial sectors with the help of professors and university students. 3 - the need to match the needs of the market and education outputs to reduce unemployment, in addition to the vocational education has become an urgent need at this stage to keep pace with the needs of life in society away from the negative view of this education. 4 - Increasing the number of technical workshops and providing them with the means of material in order to provide the university student maximum desired learning. Enhancing the role of higher education in building a broader partnership and cooperation with various other community institutions (public, private and private sector). 6 - Re-admission plan in universities by making the number of admissions in scientific colleges more than the number of admissions in the humanitarian colleges. 7 - Attracting foreign investment companies to invest natural resources in Iraq such as phosphate, natural gas, oil, oil shale, uranium, silica and geothermal energy for the recovery of the economy and the trend towards domestic consumption.

The paper presents an agent-based model reproducing a stylized credit network that evolves endogenously through the individual choices of firms and banks. We introduce in this framework a financial stability authority in order to test the effects of different prudential policy measures designed to improve the resilience of the economic system. Simulations show that a combination of micro- and macroprudential policies reduces systemic risk but at the cost of increasing banks’ capital volatility. Moreover, the agent-based methodology allows us to implement an alternative meso regulatory framework that takes into consideration the connections between firms and banks. This policy targets only the more connected banks, increasing their capital requirement in order to reduce the diffusion of local shocks. Our results support the idea that the mesoprudential policy is able to reduce systemic risk without affecting the stability of banks’ capital structure.

Agent-based models (ABMs) have been attracting the attention of researchers in the social sciences, becoming a prominent paradigm in the study of complex social systems. Although a great number of models have been proposed for studying a variety of social phenomena, no general agent design methodology is available. Moreover, it is difficult to validate the accuracy of these models. For this reason, we believe that some guidelines for ABMs design must be devised; therefore, this paper is a first attempt to analyze the levels of ABMs, identify and classify several aspects that should be considered when designing ABMs. Through our analysis, the following implications have been found: (1) there are two levels in designing ABMs: the individual level, related to the design of the agents' internal structure, and the collective level, which concerns the design of the agent society or macro-dynamics of the model; and (2) the mechanisms of these levels strongly affect the outcomes of the models.

AbstractThere is a range of public health tools and interventions to address the global pandemic of COVID-19. Although it is essential for public health efforts to comprehensively identify which interventions have the largest impact on preventing new cases, most of the modeling studies that support such decision-making efforts have only considered a very small set of interventions. In addition, previous studies predominantly considered interventions as independent or examined a single scenario in which every possible intervention was applied. Reality has been more nuanced, as a subset of all possible interventions may be in effect for a given time period, in a given place. In this paper, we use cloud-based simulations and a previously published Agent-Based Model of COVID-19 (Covasim) to measure the individual and interacting contribution of interventions on reducing new infections in the US over 6 months. Simulated interventions include face masks, working remotely, stay-at-home orders, testing, contact tracing, and quarantining. Through a factorial design of experiments, we find that mask wearing together with transitioning to remote work/schooling has the largest impact. Having sufficient capacity to immediately and effectively perform contact tracing has a smaller contribution, primarily via interacting effects.

Abstract Technology adoption in low-income regions is among the key challenges facing international development projects. Nearly 40% of the world's population relies on open fires and rudimentary cooking devices exacerbating health outcomes, deforestation, and climatic impacts of inefficient biomass burning. Clean technology alternatives such as clean cookstoves are among the most challenging technologies to approach their target goals through sustainable adoption due to a lack of systematic market-driven design for adoption. Thus, a method is needed to provide insight regarding how target customers evaluate and perceive causes for adopting a clean technology. The holistic approach of this study captures technology adoption through lenses of social networks, individual and society scale beliefs, and rational decision-making behavior. Based on the data collected in the Apac region in Northern Uganda, an agent-based model is developed to simulate emerging adoption behavior in a community. Then, four different scenarios investigate how adoption patterns change due to the potential changes in technology or intervention strategy. These scenarios include influence of stove malfunctions, price elasticity, information campaigns, and strength of a social network. Results suggest that higher adoption rates are achievable if designed technologies are more durable, information campaigns provide realistic expectations for users, policymakers, and education programs work toward women's empowerment, and communal social ties are recognized for influence maximization. The application of this study provides insight for technology designers, project implementers, and policymakers to update their practices for achieving sustainable and to the scale clean technology adoption rates.

Abstract: Although the Brazilian agribusiness sector’s relevance to the country has been widely recognized nowadays, to date, no study has been developed to evaluate the level of employment in this sector as a whole for Brazil. Therefore, the first objective of this study is to access the Brazilian agribusiness labor market, and to measure it, analyze its structure and characterize its workers. Agribusiness worker income differentials were also contrasted with income differentials in the aggregated non-agribusiness labor force. The main results from the study are as follows: a) in 2017, 18.2 million individuals, 20.1% of the country’s labor force, worked in the Brazilian agribusiness sector; b) agribusiness workers were predominately unskilled or semi-skilled with a low level of schooling; c) a large proportion of the sector’s labor force were not formally employed; and d) the average income of agribusiness employees was lower than that of individuals in other economic sectors. There is also extreme labor market heterogeneity among agribusiness sector segments – with the primary segment presenting a noticeably dissimilar profile – and a significant income differential associated with different labor market statuses, economic sub-sectors and locations, and with individual characteristics such as level of schooling, skin tone and gender.
