This paper presents a new spectrum and recommendations the Indonesian Government might find highly useful in attracting foreign direct investment (FDI) through electricity and water availability, Human Development Index (HDI), and COVID-19 pandemic evidence. Our study depends on cross-sectional data from 34 provinces and the time-series data from 2009 to 2020. We carry out the causality test (Dumitrescu-Hurlin) to check whether our research model is good enough to provide strategic options nationally. Furthermore, we employ the pooled ordinary least squared (POLS), fixed effect model (FEM), and random effect model (REM). The three models have so-called static panel data. Based on the Chow's and Hausman's test, we also find that the random effect is the best model to explain our empirical research. Our findings indicate that the electricity, water, HDI, and COVID-19 pandemic significantly contribute to the FDI. Our research also contributes to the literature on the predictors of FDI. This research is expected to help the Indonesian Government to make decisions on electricity, water, and human capital policy. Moreover, it highlights the direction a government or policymaker can take to attract the FDI.

Addressing the poverty gap is the key to improving economic welfare and improving the structure of purchasing power in society. This paper wants to analyze how increased education participation, access to clean water, and sanitation water reduce poverty disparities. The data analyzed in this study covered 501 districts and cities throughout Indonesia in 2018. The methodology used was an econometric approach with multiple regression equation models with robustness provisions. The calculation results prove that the model has been robust and all variables selected have a significant effect on the degree of freedom of 5% for all districts and cities in Indonesia. This study suggests that education policy priorities, the availability of clean water and adequate distribution, and sanitation facilities are needed to reduce the poverty gap.

Objective: While environmentally friendly products and brands are widely available, consumer adoption and usage of these products remain relatively low, highlighting disconnection between pro-environmental values and actual green practices related to green brand. This discrepancy is attributed to biased perceptions toward green brands. This study aims to address the perception bias issue in the relationship between pro-environmental values and behaviors, focusing on green personal care brands. Theoretical framework: Based on Stimulus Organism Response theory combined with Self-Verification Theory, Consumer Culture Theory and Social Exchange theory, this study proposes that individual factors such as Environmental Self-Identity and brand related factors such as Self-Green Brand Connection, Brand Trust, and Green Brand Experience play crucial roles in influencing Green Brand Evangelism with Green Brand Experience acting as a mediator in these relationships. . Method: Utilizing a non-probability purposive sampling approach, data was collected from 404 respondents through an online questionnaire using a 1-7 Likert scale. The Partial Least Squares Structural Equation Modeling (PLS-SEM) method was employed for data analysis. Results and conclusion: The findings of this research indicate that Green Brand Experience significantly mediates the impact of Environmental Self-Identity, Self-Green Brand Connection, and Brand Trust, on Green Brand Evangelism. This study represents a pioneering effort in examining the influence of Environmental Self-Identity on Green Brand Experience and Green Brand Evangelism. And the first attempt in investigating the mediating role of Green Brand Experience in shaping Green Brand Evangelism. This research contributes to a better understanding of how social-constructed green brand experiences can foster Green Brand Evangelism among consumers.
