Publication Metadata only What factors drive gender differences in the body mass index? Evidence from Turkish adults(2023-05-01) ÇAĞLAYAN AKAY, EBRU; ÇAĞLAYAN AKAY E., ERTOK ONURLU M., Komuryakan F.In recent years, studies show that obesity has become an important health condition, especially among adults. The first aim of this study is to examine socio-demographic and behavioural factors on body mass index distribution of male and female adults over 20 years old in Turkey. The second aim is to determine the body mass index disparity by gender and the socio-demographic and behavioural factors that might wider or narrow it. This study adopts unconditional quantile regression and decomposition methods, and the data set covers the Turkish Health Surveys for 2014, 2016, and 2019. The findings document that high level of body mass index are associated with being married, aging, and physical inactivity. Interestingly, employment status has different contributions on the body mass index of males and females. The results also claim a body mass index gap among males and females as a result of differences in some potential socio-demographic and behavioural factors, and the gap gets higher at the upper and lower quantiles of BMI distribution. This study may provide a clear understanding for policymakers on how to design efficacious obesity policies considering the differences in the effect of socio-demographic and behavioural factors on the distribution of body mass index across females and males. The results suggest that the Ministry of Health should specifically target different groups for males and females and should reduce the differences in socio-demographic and behavioural determinants between females and males to prevent and reduce obesity prevalence in Turkey.Publication Metadata only Çevresel kuznets eğrisi hipotezinin panel kantil regresyon yaklaşımı ile analizi(2022-09-23) ÇAĞLAYAN AKAY, EBRU; Çağlayan Akay E., Oskanbaeva Z.Publication Open Access Health econometrics research: A bibliometric analysis from 1991 to 2020(2023-06-01) ÇAĞLAYAN AKAY, EBRU; ERGÜT, ÖZLEM; Çağlayan Akay E., Ertok Onurlu M., Ergüt Ö.As a discipline, econometrics provides quantitative insights for many fields of economics, and as a result, many subfields of econometrics have emerged over time. “Health Econometrics” is one of those subfields, which employs econometric theory for the issues in health economics. The number of studies gathering econometrics and health economics, and thereby health econometrics, increased over time, particularly during the 1990s. There is a substantial body of literature in health economics that shares insights on published materials. However, the number of research that use bibliometric analysis to study trends and the present state of health econometrics is limited. This research intends to investigate published materials in health econometrics from a variety of perspectives. To do this, data from publications with appropriate subject characteristicsin the EconLit database were collected between January 1991 and December 2020. The primary methodologies in the study were bibliometric analysis and scientific mapping. The overall findingsindicate that the number of publications has grown significantly over the previous 60 years, with the highest contributing writers primarily based in American institutions. In other words, health econometrics is gaining popularity among academics in the United Kingdom and the United States.Publication Open Access Relationship between tourism and economic growth a granger causality panel data approach(2012-09-01) ÇAĞLAYAN AKAY, EBRU; ŞAK, NAZAN; Çağlayan Akay E., Şak N., Kamal K.This paper investigated the causal relationship between tourism revenue and gross domestic product (GDP) using the panel data of 135 countries for the period 1995–2008. For this purpose, Panel Granger causality analysis was applied to 11 groups of countries. This classification was created as America (30 countries), Asia (34 countries), Europe (37 countries), East Asia (13 countries), South Asia (6 countries), Central Asia (5 countries), Latin America & Caribbean (28 countries), Oceania (7 countries), Middle East & North Africa (11 countries), Sub Saharan Africa (24 countries) and the world (135 countries). Results indicated bidirectional causality in Europe between tourism revenue (TR) and gross domestic product (GDP). Findings showed that there is a unidirectional causality in America, Latin America & Caribbean and World from GDP to tourism revenue. While in case of East Asia, South Asia and Oceania the reverse direction of causality was found from tourism revenue to GDP. No causal relationship was found in Asia, Middle East and North Africa, Central Asia and Sub Saharan Africa.Publication Metadata only Testing the validity of enviromental kuznets curve in the context of green growth: evidence from panel quantile regression model(2023-11-04) ÇAĞLAYAN AKAY, EBRU; Çağlayan Akay E., Ertok Onurlu M., Oskonbaeva Z.Publication Open Access Identifying tourism and economic growth nexus the hurlin venet approach(2013-04-01) ÇAĞLAYAN AKAY, EBRU; ŞAK, NAZAN; Çağlayan Akay E., Şak N., Kamal K.This paper seeks to identify causality between tourism and economic growth within Hurlin-Venet approach using the panel data of 135 countries for the period 1995–2008. Countries are classified by income levels. The unidirectional causality from economic growth to tourism revenue is found only in case of high income countries group.Publication Metadata only Beş yaş altı çocuk ölüm hızının mekânsal probit modeli ile analizi(2023-03-23) ÇAĞLAYAN AKAY, EBRU; Çakır N. Z., Çağlayan Akay E.Publication Metadata only The effects of education and experience on youth employee wages: the case of Turkey(2022-01-01) ÇAĞLAYAN AKAY, EBRU; ÇAĞLAYAN AKAY E., Komuryakan F.The aim of this study is to reduce the disadvantages experienced by young Turkish employees, such as age discrimination, by analysing their wage structure and the factors that could affect their earnings. This study could fill the gaps in the literature on youth employee wages in the Turkish labour force. Using the 2018 Household Budget Survey data, this study addresses five research questions by estimating the extended Mincer wage equation with robust estimators to respond to the research questions. The findings show that postgraduate and bachelor\"s degrees have a high incremental effect on wages and the wage gaps between the degrees are wide. Each added year of experience impacts wages because employers prefer more experienced employees to avoid the cost of training them. Young female employees earn less than young male employees because of occupational segregation, motherhood penalty, and gender norms. Due to the lack of opportunities for part-time jobs in the Turkish labour force, there is a wide gap between the wages for full-time and part-time jobs. This study contributes to a better understanding of young employees\" wage structure with robust-to-outliers econometric analysis and may guide to develop techniques to reduce the disadvantages for young Turkish individuals in the labour market.Publication Open Access Students in Turkey during the early days of the COVID-19 pandemic(2023-02-01) ÇAĞLAYAN AKAY, EBRU; DUMLUDAĞ, DEVRİM; BÜLBÜL, HOŞENG; ZÜLFÜOĞLU, ÖZKAN; ÇAĞLAYAN AKAY E., DUMLUDAĞ D., BÜLBÜL H., ZÜLFÜOĞLU Ö.This study aims to analyse the subjective well-being of university students during the early days of the COVID-19 pandemic process and to examine how students have been affected economically, psychologically and socially. Other subjects included in the scope of the study are the suitability of the physical conditions during the process of online education, the students\" motivation, and their expectations towards the future. The study also analyses the connection between these factors and the subjective well-being concepts of happiness and life satisfaction. The study focuses on students of the Faculty of Economics at Marmara University in Turkey. In total, 428 students took part in the survey prepared for the study. Descriptive analyses indicate that students have been negatively affected in terms of psychological and socio-economic factors along with subjective well-being. Ordered probit models show a statistically significant relationship between a major part of these changes and subjective well-being variables.Publication Metadata only Tarım Kaynaklı Çevresel Kuznets Eğrisi Hipotezi: Orta Asya Ülkeleri Örneği(2022-11-18) ÇAĞLAYAN AKAY, EBRU; Çağlayan Akay E., Oskanbaeva Z.
