Ekonomik Politika Belirsizliğinin Firma Büyümesine Etkisi: Türkiye Örneği
Bu çalışma, ekonomik politika belirsizliğinin (EPB) firma büyümesi üzerindeki etkisini Türkiye örneği üzerinden incelemektedir. Araştırmada, 2010 yılı birinci çeyreğinden 2023 yılı dördüncü çeyreğine kadar olan döneme ait, Türkiye’de faaliyet gösteren 227 firmaya ilişkin çeyrek dönemlik panel veri seti kullanılmıştır. Firma büyümesi, net satışlardaki yıllık yüzde değişim ile ölçülmüş ve modelin bağımlı değişkeni olarak belirlenmiştir. Ekonomik politika belirsizliği endeksi ile birlikte toplam varlık büyümesi, sabit varlık artışı, borçlardaki değişim, GSYİH büyümesi, ihracat artışı ve kredi faiz oranındaki değişim gibi hem mikro hem de makroekonomik kontrol değişkenleri de modele dahil edilmiştir. Modelde sabit etkiler yöntemi tercih edilmiştir. Elde edilen sonuçlar, EPB’nin firma büyümesi üzerinde istatistiksel olarak anlamlı ve negatif bir etkisi olduğunu göstermektedir. Zaman etkilerinin modele dahil edildiğinde de EPB’nin etkisinin kalıcılık göstermesi, bu etkinin yapısal nitelikte olduğunu ortaya koymaktadır. Ayrıca geçmiş dönem performansı, sabit varlık büyümesi ve GSYİH artışı gibi unsurlar firma büyümesini pozitif yönde etkilerken, kredi faiz oranındaki artışlar olumsuz yönde etkilemektedir. Bu sonuçlar, Türkiye gibi gelişmekte olan ülkelerde EPB’nin firmalar için ciddi bir dışsal risk unsuru olduğunu göstermekte, politika yapıcılar açısından da öngörülebilir ve istikrarlı ekonomik düzenlemelerin gerekliliğine işaret etmektedir. Çalışma, EPB'nin mikro düzeydeki sonuçlarını Türkiye örneği üzerinden detaylı bir şekilde ortaya koyarak literatüre önemli bir katkı sunmaktadır.

Economic policy uncertainty and capital investment: Evidence from European tourism firms
This paper investigates the impact of economic policy uncertainty (EPU) on the capital investment behavior of tourism firms in Europe. Using firm-level data from 4874 firms in 11 European countries for the period 2012–2022, we conduct a dynamic panel data analysis that accounts for the different effects of domestic and global policy uncertainty on the tourism industry and its sub-industries. The results reveal that both domestic and global EPU slow down capital investment in the tourism industry. Notably, global EPU has a significant negative impact in all sub-industries, while domestic EPU mainly affects the hotel sub-industry. These findings remain robust when different firm- and country-specific factors are taken into account. Our study highlights the need for policymakers to reduce policy uncertainty to encourage greater investment. Tourism managers may also benefit from considering both domestic and global uncertainties along with industry-specific characteristics in their investment decisions.

Leaving the Nest: Inquiring the Determinant Factors of Leaving the Parental Home for Young Individuals in Turkey
This paper examines the determinants of young individuals' decision to leave their parental home in Turkey in the last decade. Using data from the Household Income and Living Conditions Survey (HILCS) from 2011 to 2021, we conduct a logit regression analysis to estimate the probability of young people leaving their parental home for reasons other than marriage. In this regard, we examine the household composition in the data, and we take the situation of living away from parental home as the dependent variable. We observe that the tendency to live independently of parents has increased slightly among young people over the past decade. We examine this new household trend at its outset, and our goal is to identify the factors that lead to the decision of young individuals to live independently. The results show the importance of income, education, gender, age, employment status, and regional differences in young individuals' residential choices. In particular, we show that personal income is a determining factor from mid-youth forward, while other factors predominate in early youth, and, for women, income and occupational status appear to be the dominant factors.

Unemployment: Automation, Monopolistic and Bargaining Power
In this study, we mainly focus on the linkages between automation and unemployment under other unemployment generating structural mechanisms, which arise out of monopolistic power of firms in goods market and union power in labor market. For this, we construct a static general equilibrium model with a two-sector framework. Penetration of automation creates a widespread spillover effects on unemployment, wages of workers having different skill levels, resource allocation and income inequality. The existence of monopolistic power and union bargaining affects the way in which automation affects the variables of interest, in particular unemployment. It seems that automation turns out to be very good for growth and very bad for employment and equality. JEL Classication: O33, J63, J64, D30, J51

Exploitation of a Productive Asset in the Presence of Strategic Behavior and Pollution Externalities
We study the strategic behavior of firms competing in the exploitation of a common-access productive asset, in the presence of pollution externalities. We consider a differential game with two state variables (asset stock and pollution stock), and by using a piecewise-linear approximation of the nonlinear asset growth function, we provide a tractable characterization of the symmetric feedback–Nash equilibrium with asymptotically stable steady state(s). The results show that the firm’s strategy takes three forms depending on the pair of state variables and that different options for the model parameters lead to contrasting outcomes in both the short- and long-run equilibria.
