The concept of tax morale is introduced to measure the reason of paying taxes by subjects. The main objective of this paper is twofold. Firstly, the present paper examines potential factors that may influence the degree of tax morale in Turkey. Secondly, the paper aims to determine the best model to explain the determinants of the degree of tax morale by a comparison of alternative ordered response models. For these purposes, a written-questionnaire was administered to 943 subjects in three cities of northern Turkey, namely, Erzurum, Erzincan, and Bayburt. Standard ordered probit (OPROBIT) and alternative ordered response models including generalized ordered logit model (GOLOGIT), partial proportional odds (PPO) model and heteroskedastic ordered logit (HOLOGIT) model were performed to determine the best model fit. Results reveal that marital status, monthly income, and operation time were positively correlated with higher degrees of tax morale. The empirical findings also indicated that higher educated subjects were more likely to have lower degrees of tax morale. Tax amnesty, higher tax load, tax system, tax policies, previous negative experiences, and efficient use of public expenditures were found to have statistically significant impact on the degree of tax morale among subjects.

Following the 2007-2009 global crisis, high credit growth became an issue of concern with an emphasis on its relationship with capital flows. It is argued that large and volatile international capital flows lead to credit expansion, which in turn, may cause economic and financial instabilities when it reaches excessive levels, particularly in developing countries. This paper aims to investigate the association between credit growth and capital inflows in the context of developing countries by using panel data analysis. The methodology employed in the study offers a number advantages by allowing for heterogeneity and cross-sectional dependence in the panel, while also considering the endogeneity issue. The overall results of the study provides evidence for the impact of capital inflows, more particularly other capital inflows, on credit growth in the sample. This finding suggests a more direct relationship between capital inflows and credit creation as other inflows mostly comprise international banking and trade credits. It is not surprising given the fact that banking sector has a critical role in the financial systems of developing countries. The significance of international dimension for credit creation through other capital inflows and the intermediary role of the banking system should have monetary policy implications, in the macroprudential or more conventional fashion.

The economic growth-public expenditure relationship is one of the important subjects that both policymakers and scientists focus on during extraordinary conditions such as economic crises, natural disasters or epidemics. Despite the privatization practices and the efforts to adopt the minimal state approach proposed by neoliberalism, which have become widespread significantly since the 1970s, public expenditures increase the interest in the subject. The study analyses the validity of the Keynesian approach, which argues that public expenditures are a fiscal policy tool that supports economic growth, in G-20 countries, as opposed to Wagner's approach, which argues that economic growth is the reason for the increase in public expenditures. The analysis was carried out with the Pesaran CCEMG estimator, which considers cross-sectional dependence and heterogeneity, using annual data from 1994-2017. According to the findings, it could be stated that Wagner's Law is not valid in G-20 countries because the slope coefficient does not fulfil the condition of being more significant than 1, whereas the Keynesian approach is valid. Moreover, a bidirectional causality was discovered between economic growth and public expenditures. Consequently, public expenditures can be used as an effective fiscal policy tool to eliminate economic instabilities under political, economic, or extraordinary conditions such as COVID-19.
