Abstract

Introduction/Main Objectives: Education serves as a driving force for the transformation of society to break the cycle of poverty. This study examines the relationship between average years of schooling and per capita household expenditure in Kalimantan Tengah Province in 2020. Background Problems: The method of estimating a regression model that is assumed to follow a certain form of regression equation such as linear, quadratic and others is called parametric regression. However, researchers often encounter difficulties in determining the model specification through data distribution, so the method used is nonparametric regression. Novelty: This research uses a quantile-based approach to explore how the impact of education on per capita expenditure varies across different levels of household education. This provides a more nuanced understanding of the relationship, showing not just whether education matters, but how its influence changes at different levels of educational attainment. Research Methods: The relationship between average years of schooling and per capita household expenditure is modeled using a quantile regression model with the constrained B-Splines method. Finding/Results: Based on the established classification, it can be concluded that an increase in the average years of schooling among household members tends to have a greater impact on raising per capita expenditure.

Abstract

This study tried to analyze the factors that influence the happiness level of entrepreneurs in Indonesia especially the nascent entrepreneurs. The level of entrepreneurs’ happiness has a positive effect on the sustainability of their business. The research data are secondary data from 1,148 respondents who are included in the category of Total Early-stage Entrepreneurial Activity (TEA) at Global Entrepreneurship Monitor (GEM) in 2013. The variables employed are motivation, perception and innovation and demographic variables (gender, education and income). Analyzer used is multiple linear regressions with dummy variable. From  the result, it is found that only the motivation, education level and level of income that significantly influence the level of happiness. The nascent entrepreneurs, who have motivation to start a business because of opportunity, have a higher level of happiness than necessity motivation due to necessity. The level of education and income are also proportional to the level of happiness, but the level of education gives greater influence to the level of happiness of nascent entrepreneurs in Indonesia.
