Green products are among the widely used products worldwide due to their environmental benefits. However, information on the consumers' purchase intention towards green products in developing countries, such as Thailand, is lacking. This study aims to investigate Thai consumers who are aged over 18 years, and whose base education is high school, on purchase intention for green products by using an extended framework of the theory of planned behavior (TPB). We derived and examined the model through structural equation modeling in a sample of 483 respondents in Thailand. The findings of this model indicated that consumer attitude, subjective norm and perceived behavioral control have significant positive influences on the purchase intention for green products. Furthermore, our results indicated that environmental concerns have a significant effect on attitude, perceived behavioral control and purchase intention for green products, but subjective norm. Moreover, environmental knowledge had no significant effect on the purchase intention for green products. Instead, it had a distinct indirect effect through attitude towards purchasing green products, subjective norm and perceived behavioral control. The findings from this study contribute to improving the understanding of intention to purchase green products, which could play a major role towards sustainable consumption.

ABSTRACT

Rubber is one of Indonesia's leading plantation commodities that is oriented to the international market with export destination countries to several countries. Rubber provides a positive contribution to the economy because it generates foreign exchange for the country. This study aims to analyze (1) the factors that influence the price of Indonesian natural rubber exports and (2) the position of Indonesia's rubber competitiveness in comparative and international competitive advantages. This study uses time-series data is from 1995 to 2017. Data were analyzed using multiple linear regression for influence factors the price of Indonesian natural rubber exports, while to analyze the position competitiveness of Indonesian natural rubber that is by using a revealed comparative advantage (RCA), and competitive advantage by using the Trade Specialization Index approach (TSI). The results of this study show (1) the factor that significantly affects the price of Indonesia's natural rubber exports are international rubber prices, exchange rate, and domestic consumption.(2) Based on competitiveness analysis, through Revealed Comparative Advantage (RCA) indicate that the competitiveness of Indonesia's natural rubber exports on the international market has a comparative advantage seen from 1995-2017 with an average value of RCA> 1 which is equal to 1.01. While the competitive advantage for the competitiveness of Indonesian rubber exports is at the maturation stage. This condition occurs because the value of the Trade Specialization Index (TSI) approaches 1, which is 0.98.

This study aims to investigate the determinants that influence purchase intention towards green products of young Thai consumers group among 18 to 29 year olds. We derived and examined the model through structural equation modeling (SEM) in a sample of 425 young respondents in Thailand. Our results indicated that environmental consciousness, environmental knowledge and environmental attitude have significant positive influences on purchase intention towards green products. Hence, environmental attitude had high significant effect on consumers' purchase intention, which reflects that the young consumers have a positive attitude towards green products, thus, making them more purchase intention. Moreover, our results suggest that environmental attitude mediates the relationship between environmental consciousness, environmental knowledge and purchase intention towards green products of young consumers group in Thailand.

Krause J., Machek O. (2018): A comparative analysis of organic and conventional farmers in the Czech Republic. Agric. Econ. -Czech, 64: 1-8. Abstract:Organic farming has become a topic that receives an increasing academic as well as popular attention. Th is study examines the fi nancial diff erences between the organic and conventional farmers, as well as their income volatility. Based on the Student's t-test, the regression analysis and the matched-pair investigation on a sample of Czech 291 organic and 4045 conventional farmers over the period 2009-2013, the study indicates that the organic agricultural companies outperform the conventional companies in the terms of profi tability. However, their asset turnover is considerably lower. No evidence of diff erent income volatility has been found.
