    Effects of indoor air pollution on household health: evidence from Turkey
    (Springer Heidelberg, 2021) Ipek, Ozlem; Ipek, Egemen
    Indoor air pollution caused by the use of biomass energy in heating and cooking adversely affects the health status of household members. In Turkey, with the rapid economic growth of the last decade, biomass has been among the most consumed types of household energy for heating and cooking due to inadequate infrastructure, dependence on foreign energy, and high energy prices. This study aims to add empirical evidence to the literature on health status and indoor air pollution in Turkey caused by households' energy choices. This study analyzed these effects with random effects panel discrete ordered models using the Income Living Conditions Micro Longitudinal Data Set for the period 2014-2017. As a result of the analysis, we found that the factors of age, being female, having dependent children, and indoor air pollution have adverse effects on health status. However, education level and income level affect health status positively. The most important observation obtained from this study is that even high-income households are adversely affected by indoor air pollution due to the lack of access to clean energy resources.

    Revealed Preferences Theory: An Experimental Approach
    (Sosyoekonomi Soc, 2021) Ipek, Ozlem; Akyazi, Haydar
    In this study, the validity of the revealed preference axioms is tested by experimental data using non-parametric methods. In the experimental setup established to determine the preference structures of the consumers under different price and quantity scenarios, the subjects are asked to choose between two goods first and then eight different goods representing the multi-goods situation under different budgets. The results of the experiments show that, for both scenarios, all of the 107 people who participated in the experiment provided the GARP axiom and the WARP and SARP axioms. This result indicates that the preferences of all subjects consistent with the revealed preferences theory, which means that the subjects have rational preferences.

    REVEALED PREFERENCES: THEORY AND APPLICATION
    (Mehmet Akif Ersoy Univ, 2021) Ipek, Ozlem; Akyazi, Haydar
    In this study which aims to test validity of the revealed preference theory for Turkish households, determine the rationality in consumer preferences and measure welfare loss in case of violation of rationality, the revealed preference axioms are analyzed by using non-parametric methods over cross-sectional data. In the application where consumer behaviors of Turkish households are analyzed, 2004-2017 period Turkey Statistical Institute Household Budget Survey data set is used. The revealed preference axiom violation rates and rationality indices are calculated by considering preferences of households under the assumption of a unitary and collective consumption model. Findings show that households exhibit highly consistent behaviors with axioms. In addition, it is obtained that households used their incomes effectively during the analysis period, unexpected changes in prices have significant negative effects on consumer rationality and this causes an average welfare loss of 25% in households. It is also seen that the preferences created under the assumption of collective consumption model are less violating rationality and caused less loss of wealth. Finally, it is determined that socioeconomic variables such as age, education, gender and income status of individuals have an impact on preference rationality.

    The Dynamics of Household Food Insecurity in Turkey
    (Sosyoekonomi Soc, 2022) Ipek, Ozlem
    Fundamental needs such as adequate food, clothing, and shelter are the foundation of social well-being. With the increasing world population, the number of undernourished people is also gradually increasing. This situation triggers increased concern that groups with different socioeconomic characteristics in developing countries will not have sufficient access to the food necessary for a healthy life. Consequently, the food insecurity issue has become a global topic of interest. Identifying the determinants of household food insecurity is important to develop policies to eliminate or reduce the significant inequalities in households' access to food. This study seeks to identify the dynamics of households' food insecurity in Turkey through Income and Living Conditions Longitudinal Microdata applying the random effects logit model. We found that as education level, health status, and income increase, the likelihood of food insecurity significantly decreases. The probability of food insecurity for males is 4% higher than for females. Education and income are the most influential variables of food insecurity. We also measured the average increase in food insecurity over the years compared to the reference year of 2014. Food insecurity has increased by more than 1.5 over the years in Turkey.

    The Impacts of Financial Resource Management on Financial Worries
    (Eskisehir Osmangazi Univ, Fac Education, 2024) Ozbilge, Gokhan; Canatan, Behice; Ipek, Ozlem
    This study aims to investigate the possible causes of totalfinancial worryand COVID-19 induced financial worries, which include all of these in addition to the four common forms of financial worries arising from old age, payments, health, and education, for the Turkish sample. The empirical bases of financial behavior, financial resilience, social assistance, and socioeconomic factors, which are discussed and explained within the Family Resource Management Model framework, are obtained from the 2021 Global Findex dataset using an ordered logit model. The findingsindicate that reducing financial worries in Turkey is associated not only with income growth but also with financial behavior and resilience, which require financial resource management
