Limited access to regional and sectoral economic data hinders effective policy design in various countries. To address this issue, this study explores the potential of higher-quality nighttime light (NTL) data to predict economic activity across various sectors within regions. We analyze the relationship between NTL intensity and sectoral GDP in 81...

This paper introduces a newly developed unit root test procedure named the Fourier Quantile AESTAR (FAESTAR-QKS) test that allows nonlinearity and structural changes. The FAESTAR-QKS unit root test is mainly based on the quantile approach and provides more powerful results since it is robust toward non-normal errors. Then, we test the Purchasing Po...

One of the Sustainable Development Goals (SDGs) of the United Nations is to promote, sustained, inclusive, and sustainable economic growth. However, it is observed that many countries struggle to move up from the middle-income to high-income level, which refers to the middle-income trap (MIT). In this paper, we test the MIT hypothesis using a novel...

This article explored the impact of eco-friendly houses on economic development in the Lisbon metropolitan area. The study analyzed data from 18 municipalities between 2014 and 2020 using regression analysis with ordinary least squares (OLS) and fixed effects. The results indicate that national policies promoting residential energy efficiency posit...

This study investigates the convergence process of environmental-related technologies patents over the period 1991-2019 across 36 OECD countries. To do so, the club convergence methodology of Phillips and Sul is used, which allows the authors to analyze overall convergence and identify possible convergence clubs. The log-t test results show that OE...

This research examines the effect of energy efficiency regulations on reducing energy poverty in residential dwellings in 18 municipalities of the Lisbon metropolitan area from 2014 to 2020. In its empirical investigation, this study uses Ordinary Least Squares (OLS) with fixed effects and Moments Quantile Regression (MM-QR) methodologies. The resu...

The demographic structure of countries has significant effects on economic growth. Most developing countries are passing through a demographic transition. Although African countries still have higher fertility rates than other developing countries, fertility rates show a decreasing trend, which leads to a window of opportunity for potential demogra...

This study investigates the convergence in ecological footprint per capita across Southern Common Market countries over the period 1961–2016 within the framework of the environmental convergence hypothesis. However, unlike the existing literature, which mainly tests the convergence for the overall period, this study follows a different path. First,...

This paper studies regional income convergence and its conditioning factors across 81 provinces of Turkey over the 2007–2019 period. Through the lens of a nonlinear dynamic factor model, we first test the hypothesis that all provinces would eventually converge to a common long-run equilibrium. We reject this hypothesis and find that the provincial...

In this paper, we investigate the convergence in ecological footprint per capita across the ECOWAS (Economic Community of West African States) countries from 1968 to 2017. For this aim, we apply a panel Fourier threshold unit root test recently proposed by Yilanci et al. (2021). This methodology considers both multiple smooth structural changes and...

Research and development (R&D) expenditures promote economic growth and development by increasing productivity and innovation. In this paper, we analyze the convergence in R&D expenditures in OECD countries over the period 1996-2018, employing the club convergence methodology developed by Phillips and Sul (2007). The results show that there is no o...

The demographic structure of countries has an important role in the growth and development process. Turkey is one of the countries which has not yet completed the demographic transition process, and the demographic window of opportunity still exists in Turkey. Taking advantage of the demographic window of opportunity depends on policies to be imple...

In this paper, we examine the impact of globalization on ecological footprint within the framework of the environmental convergence hypothesis for 130 countries over 1980–2016. To do so, we follow a two-stage empirical procedure. First, we test the overall convergence in ecological footprint across countries and identify possible convergence clubs...

This study investigates the interaction effect of globalization and human capital on economic growth in Turkey. The autoregressive distributed lag (ARDL) bounds testing approach is applied in the study, and the dataset covers the period 1984-2017. The results show that the impact of globalization on economic growth is conditional on the human capit...

In this paper, we investigate the macroeconomic, demographic and institutional factors affecting the probability of growth slowdown in upper-middle-income countries within the framework of the growth slowdown methodology developed by Eichengreen et al. (2011). To do so, we use probit regression, and the dataset covers the period 1980-2015. The resu...

While the impacts of a university on the formation of human capital and scientific progress are well-known, impacts on the surrounding economy have been argued since Caffrey and Isaacs (1971). The economic impacts of a University on a local level can be considered, mainly, as expenditures and employment. Expenditures are generally, classified as ex...

Orta gelir tuzağı, özellikle gelişmekte olan ülkeler açısından ciddi bir problem olarak karşımıza çıkmaktadır. Orta gelir tuzağı, hızlı bir büyüme sonrası düşük gelir seviyesinden orta gelir seviyesine ulaşan ülkelerin, büyüme yavaşlaması sonrası yüksek gelir grubuna geçemediği durumu ifade etmektedir. Bu çalışmada, Eichengreen vd.’nin (2011) çalış...

Özet Bu çalışmanın amacı Kurumsal İktisadın yapısını ve önemini incelemek, ayrıca Eski ve Yeni Kurumsal İktisadın teorik gelişimini ve ayrışmasını eleştirel olarak değerlendirmektir. Çalışmada, disiplinler arası karaktere sahip olan Kurumsal İktisadın, ekonomik faaliyetlerin kurumsal temellerini ortaya koyarak ve işlem maliyetleri, mülkiyet hakları...
