“…Based on the fact that expenditures can never be negative in his study, Tobin assigned a value of zero to this variable until the household income exceeds a certain level. The model he described in those years is a classic example of a regression model for review [19,20].…”

Although some of the resources required to meet human needs can be provided by a country, the rest must be supplied from other countries because not every country has all resources. Therefore, the demand for international trade emerges. A country earns incomes by selling its surplus and obtains scarce resources from other countries with these incomes. In this context, some political and economic initiatives have been established by countries, which work in harmony to facilitate and regulate international trade and create a common market. Two of them are Shanghai Pact and the Belt and Road Initiative (BRI). However, even if the initiatives meet certain common needs, it is very important to carry out logistics activities correctly in order to ensure effective and efficient foreign trade. If planned and correctly carried out, logistics activities are expected to make both import and export processes efficient and reduce resource usage. In this study, it is aimed to examine the effects of logistics performance in international trade in countries of Shanghai Pact and the BRI. In order to measure logistics performance in the research, two kinds of data are used, namely, the Logistics Performance Index (LPI) data, published by the World Bank every two years, and the import and export data, also published by the World Bank. With six sub-criteria of LPI modeled as independent variables and import and export as dependent variables, Tobit analysis is made by using EViews 10 software package. According to the analysis results, customs clearance, logistics quality and traceability have effects on export, and infrastructure, customs clearance and logistics quality have effects on import.

“…In the analysis of the consumption of ornamental plants and flowers, the Tobit model, which is widely used to explain models with limited dependent variables, was used. The model is a linear regression model with non-negative dependent variables and is based on variables that do not take negative values such as price, wage, and expenditure [30], [31].…”

Ornamental plants are a sector that meets the spiritual and visual needs of people, improves the physical properties of the space they are used in, and contributes significantly to the economy and employment with the added value it creates. Şanlıurfa has an important potential for ornamental plants due to its geothermal resource and seasonal characteristics. The purpose of this study is to determine the factors that affect the consumption behavior of ornamental plant consumers in Şanlıurfa. The material of this research consists of data obtained from face-to-face surveys with consumers selected by a simple random sampling method in Şanlıurfa, and the surveys were conducted in 2020. Multinomial probit, negative binomial regression, and Tobit models were used in the analyzes. According to the results, the gender, marital status, income, employment status, and education level of the participants were determined as effective factors at different statistical significance levels. It was determined that age is not an effective factor. When the income level rises by one level, the ornamental plant expenditure increases by 19.93 TL annually, and when the education level rises by one level, it increases by 17 TL. The spread of ornamental plant cultivation should be encouraged in Şanlıurfa. This study is the first kind on this subject in Şanlıurfa.

In this study, it is aimed to compare the performance of European Union (EU) members' and candidate countries' health systems. In this context, two-step analysis method was used in the study. In the first stage, Data Envelopment Analysis (DEA) was conducted in order to determine the health care performance of the countries, while the second stage analysis attempts to determine whether the varying methods employed by the countries to finance their health systems has a statistically significant effect on the DEA scores. In the utilized Tobit regression model, the transformed DEA score was taken as the dependent variable, and the financing model adopted by the countries to finance health systems was taken as the independent variable. According to the results, the financing method shows a statistically significant effect on the efficiency of the health systems. Specifically, adopting the Beveridge Model has a statistically significant positive impact on health system efficiency.
