On stability and efficiency in different economic environments

Ankara : The Department of Economics, İhsan Doğramacı Bilkent University, 2011.Thesis (Ph. D.) -- Bilkent University, 2011.Includes bibliographical references leaves 161-165.This thesis consists of four main chapters. In the first main part, hedonic coalition formation games where each player’s preferences rely only upon the members of her coalition are studied. A new stability notion under free exit-free entry membership rights, referred to as strong Nash stability, is introduced which is stronger than both core and Nash stabilities studied earlier in the literature. The weak top-choice property is introduced and shown to be sufficient for the existence of a strongly Nash stable partition. It is also shown that descending separable preferences guarantee the existence of a strongly Nash stable partition. Strong Nash stability under different membership rights is also studied. In the first main part, hedonic coalition formation games are also extended to cover formation games, where a player can be a member of several different coalitions, and these games are studied. In the second main part, Nash implementability of a social choice rule (via a mechanism) which is implementable via a Rechtsstaat is studied. A new condition on a Rechtsstaat, referred to as equal treatment of equivalent alternatives (ET EA), is introduced, and it is shown that if a social choice rule is implementable via some Rechtsstaat satisfying ET EA then it is Nash implementable via a mechanism provided that there are at least three agents in the society. In the third main part, a characterization of the Borda rule on the domain of weak preferences is studied. A new property, which is referred to as the degree equality, is introduced, and it is shown that the Borda rule is characterized by weak neutrality, reinforcement, faithfulness and degree equality. In the fourth main part, the graduate admissions problem with quota and budget constraints is studied as a two sided many to one matching market. The students proposing algorithm, which is an extension of the Gale-Shapley algorithm, is constructed, and it is shown that the students proposing algorithm ends up with a core stable matching if the algorithm stops. However, there exist graduate admissions problems for which there exist core stable matchings, while neither the departments proposing nor the students proposing algorithm stops. It is proved that the students proposing algorithm stops if and only if no cycle occurs in the algorithm. It is also shown that no random path to core stability for the graduate admissions problem exists.Karakaya, MehmetPh.D

Methodology of Islamic Economics: Typology of Current Practices, Evaluation and Way Forward

The sustainable development of Islamic economics as a discipline depends also on methodological development that provides a clear direction on how to appraise economic theories and provide evidence of its reliability. This paper attempts to study the methodology of Islamic economics in two ways: (1) by examining the works by scholars in their specific writings on this subject, and (2) by observing the writings on Islamic economics, banking, and finance to see how Islamic economists develop their discipline. The paper found three categories of writings, namely: (1) the usul al-fiqh methodology applied in economics, (2) methodological pluralism that tries to utilize various methodologies developed in both western and Islamic tradition, and (3) the conventional mainstream positive economic methodology applied in Islamic cases. These are evaluated thoroughly and suggestions are made as to what needs to be done to assist Islamic economics’ development

Proceedings of the 1st International Conference on ASEAN (IC-ASEAN) "Towards a better ASEAN", September 5-6, 2019; Padang, West Sumatra, Indonesia

Since the establishment of ASEAN (Association of Southeast Asian Nations) as a regional organization in 1967, it has played a significant role most importantly related to regional affairs and has also given notable contribution to the international arena. Undisputedly, ASEAN has been successfully fostering good relations among its members since its foundation. After completing the first period of its vision of an integrated regional community (ASEAN Community 2015), ASEAN is now preparing for the launch of ASEAN Community Vision 2025, supported by ASEAN Connectivity 2025. As a study center focusing primarily and solely on ASEAN, in collaboration with the Directorate General of ASEAN Cooperation, Indonesian Ministry of Foreign Affairs, the Center of ASEAN Studies Andalas University, will be hosting the International Conference on ASEAN (IC-ASEAN) as a platform to evaluate past actions, to discuss present issues, and to provide an outlook for the future of ASEAN. Aims and Scope The International Conference on ASEAN (IC-ASEAN) is a multidisciplinary conference which covers a broad range of area. The sub theme will be divided into two large categories focusing on ASEAN Community 2015 and 2025 also ASEAN Connectivity 2025. The sub theme related to ASEAN Community will cover issues related to the three pillars (Political-security Community, Economic Community and Social-cultural Community). Meanwhile the ASEAN Connectivity sub theme will include issues within the key areas (Physical Connectivity, Institutional Connectivity and People-to-people Connectivity

Proceedings of the International Congress on Interdisciplinarity in Social and Human Sciences

Interdisciplinarity is the main topic and the main goal of this conference. Since the sixteen century with the creation of the first Academy of Sciences, in Napoles (Italy) (1568), and before that with the creation of the Fine Arts Academies, the world of science and arts began to work independently, on the contrary of the Academy of Plato, in Classical Antiquity, where science, art and sport went interconnected. Over time, specific sciences began to be independent, and the specificity of sciences caused an increased difficulty in mutual understanding. The same trend has affected the Human and Social Sciences. Each of the specific sciences gave rise to a wide range of particular fields. This has the advantage of allowing the deepening of specialised knowledge, but it means that there is often only a piecemeal approach of the research object, not taking into account the its overall complexity. So, it is important to work for a better understanding of the scientific phenomena with the complementarity of the different sciences, in an interdisciplinary perspective. With this growing specialisation of sciences, Interdisciplinarity acquired more relevance for scientists to find moreencompassing and useful answers for their research questions.info:eu-repo/semantics/publishedVersio

Psychological Engagement in Choice and Judgment Under Risk and Uncertainty

Theories of choice and judgment assume that agents behave rationally, choose the higher expected value option, and evaluate the choice consistently (Expected Utility Theory, Von Neumann, & Morgenstern, 1947). However, researchers in decision-making showed that human behaviour is different in choice and judgement tasks (Slovic & Lichtenstein, 1968; 1971; 1973). In this research, we propose that psychological engagement and control deprivation predict behavioural inconsistencies and utilitarian performance with judgment and choice. Moreover, we explore the influences of engagement and control deprivation on agent’s behaviours, while manipulating content of utility (Kusev et al., 2011, Hertwig & Gigerenzer 1999, Tversky & Khaneman, 1996) and decision reward (Kusev et al, 2013, Shafir et al., 2002)

Secondary cities as catalysts for nutritious diets in low- and middle-income countries

The world is facing a malnutrition crisis in the midst of rising rates of urbanization; more than half of the world's population lives in urban areas, a number that is expected to reach two-thirds by 2050, consuming 80% of the world's food. Instead of the development of existing cities into 'mega-cities, ' urbanization is creating a patchwork of smaller urban areas. In 2018, close to half of the world's urban residents lived in settlements or towns with less than 500, 000 inhabitants. These settlements are classified as secondary cities and are, in terms of population, the fastest growing urban areas. Poor diets among city inhabitants are the consequence of a combination of forces. These include changes in types of occupation, particularly for women; food-environment factors; shifts in norms and attitudes regarding food; globalization of food supply chains; lack of infrastructure; post-harvest food loss and waste, etc. Secondary cities offer entry points for food system transformation. Secondary cities are characterized by strong urban-rural linkages and the opportunity for localized food production and consumption. These cities could also play a key role in enhancing resilience to food security shocks. This chapter discusses the challenge of the growing triple burden of malnutrition in urban contexts and argues for the important role of secondary cities in transforming urban food systems. Through three case studies of secondary cities in LMICs, these cities are shown as emerging players in nutrition-centered food system interventions. © The Author(s) 2023
