- ItemSpatial analysis of the macroeconomic determinants of crime: Evidence from regions of Türkiye(Elsevier, 2025-09) Şengül, Serkan; Canbay, Şerif; 355807This study investigates the macroeconomic and spatial determinants of crime rates in Türkiye by employing spatial panel data models. Using annual data from 12 NUTS-1 regions over the period 2009–2022, the analysis examines the effects of unemployment rate, income inequality (Gini coefficient), inflation rate, per capita income (GDP), public education expenditures, and urbanization on crime rates. Recognizing the spatial dependence structure of regional data, spatial error models are preferred over classical panel estimators. In addition to total crime, the study disaggregates crime data into two major categories—assault and theft—to assess the robustness of results and explore type-specific dynamics. The findings reveal that income inequality, per capita income, and inflation have positive and statistically significant effects on crime rates across all models. While public education expenditures do not exhibit a significant direct effect, their spatially lagged values show a negative and significant relationship with both total and disaggregated crime categories. The urbanization variable is found to reduce theft rates, although its effect on assault is weaker and not consistently significant. The unemployment rate does not appear to be a significant determinant in most specifications. These results highlight the importance of spatially informed, region-specific crime prevention strategies. In particular, the findings emphasize the relevance of interregional spillover effects of education policy and the differentiated impact of urbanization on distinct types of crime. The study contributes to the literature by offering both empirical and methodological advancements through the use of disaggregated crime data and spatial econometric techniques.
- ItemCapital-Labor-Output Nexus in Türkiye's Fisheries Sector: Panel ARDL Analysis(Isparta University of Applied Sciences, 2025-09) Şengül, Serkan; 355807This study analyzes the relationship between production, labor force and capital investments in the fisheries sector in the Marmara, Aegean, Mediterranean, Western Black Sea and Eastern Black Sea regions of Türkiye and examines their effects on sectoral growth and employment. In the study, total fish production, number of employees in the sector and capital investments (number of vessels) variables are used in the panel data analysis covering the period 2006-2023. According to the results of the analysis, the labor force has a positive and significant effect on production, but the effect of capital on production is negative. This shows that capital investments in the Turkish fisheries sector have not been able to provide the expected productivity growth. Moreover, capital investments are found to support employment by increasing labor demand. The long-run cointegration results reveal a strong equilibrium relationship between the variables. This study contributes to the existing research in the literature and provides strategic recommendations for the development of sustainable growth and productivity policies in Türkiye's fisheries sector. In particular, supporting aquaculture activities, modernizing capital investments and taking regional differences into account are critical for the long-term sustainability of the sector.
- ItemGıda Güvenliğinin Ekonomik ve Çevresel Belirleyicileri: BRICS-T Ülkeleri İçin Bir Analiz(Dokuz Eylül Üniversitesi, 2025-07) Şengül, Serkan; Köprücü, Yılmaz; 355807Bu çalışma, BRICS-T ülkelerinde gıda güvenliğini etkileyen ekonomik ve çevresel faktörlerin uzun dönemli etkilerini analiz etmektedir. Çalışmada, gıda güvenliği endeksi, karbon emisyonları, kişi başına düşen gelir, nüfus artış oranı, ve enflasyon değişkenleri incelenmiştir. Panel eşbütünleşme testi ve FMOLS yöntemleri kullanılarak, karbon emisyonlarının gıda güvenliği üzerinde pozitif bir etkisi olduğu, ancak bu etkinin çevresel sürdürülebilirlik açısından risk oluşturabileceği tespit edilmiştir. Bulgular, sürdürülebilir tarım teknolojilerine yatırım yapılması, doğal kaynakların korunması ve uluslararası işbirliklerinin artırılması gerektiğine işaret etmektedir. Çalışma, BRICS-T ülkelerinin farklı ekonomik ve çevresel koşulları ışığında literatüre yeni bir bakış açısı sunmaktadır.
- ItemProduction and Sustainability in Türkiye's Fisheries Sector: The Role of Economic Variables(Çanakkale Onsekiz Mart University, 2025-07) Şengül, Serkan; 355807This study investigates the impact of basic economic variables on production processes in Türkiye's fisheries sector, emphasizing sustainable development strategies. Using a dataset from the Turkish Statistical Institute covering annual data from 2003 to 2023, the research employs the ARDL model to examine the long-term and short-term effects of capital investments, labor costs, and energy expenses on total production. Results indicate that capital investments significantly enhance productivity, though misallocation can negatively impact efficiency. Labor and energy costs exhibit a negative effect, underlining the importance of cost optimization for sectoral sustainability. Based on these findings, the current study proposes strategic policy recommendations such as; efficient capital allocation, labor cost optimization through training programs, and the adoption of renewable energy sources to reduce operational expenses. These recommendations aim to support sustainable growth in the Turkish fisheries sector, enhance food security, and bolster economic resilience.
- ItemFrom capture to culture: the asymmetric impact of education on Türkiye's fisheries sector(Springer, 2025-08) Canbay, Şerif; Şengül, Serkan; Karahan Dursun, Pınar; 355807; 414023The aim of this study is to analyze the causal effect of the net schooling rate, as a proxy for human capital, on saltwater fisheries and aquaculture in five coastal regions of T & uuml;rkiye (Marmara, Aegean, Mediterranean, Western Black Sea, and Eastern Black Sea). In the empirical analysis, we use the panel data for the period 2009-2022 and employ the dependent variables that are the amount of fish production obtained through fishing in Model 1 and the amount of fish produced through aquaculture in Model 2. The study applies the panel bootstrap Granger causality method, considering both structural heterogeneities and cross-sectional dependencies. The results show that the effect of educational attainment on fish production activities varies both by type of production and by regional conditions. In the Mediterranean and Aegean regions, educational attainment has strong effects on both fishing and aquaculture, while in some regions, it has a negative effect on production. The study contributes to the literature by presenting the effects of education, a socio-economic variable, at the sectoral level in detail; it also provides an empirical basis for the development of region-specific sustainability policies.
