Although the government of Indonesia is building the cashless society, the number of e-wallet users are increasing slowly. E-wallet is becoming a common instru­ment of payments from the paper-based instruments to server-based electronic money. The aim of this research is to investigate the perceived usage of the Y Genera­tions on e-wallet based on Technological Acceptance Model (TAM) which is a power­ful model to describe single approval to the usage of a new information technology system. As a quantitative research, the data analysis is using the Partial Least Square (PLS) with the SmartPLS 3.0 software. The results show that perceived usefulness and perceived ease of use brings impacts positive significant impacts to behavioural intention to use, then, the behavioural intention to use affect a positive significant impact to perceived usage. However, a direct effect from perceived useful­ness to perceived usage shows a negative and no significant impact, meanwhile an unintended effect from perceived usefulness to perceived usage through behavioural intention to use show a positive significant impact. Finally, a direct effect from perceived ease of use to perceived usage shows a lower t-statistic value than an indi­rect effect from perceived ease of use to perceived usage through behavioural inten­tion

Generation cohorts have different tendencies in purchase behaviors, especially the Generation X and the Generation Y. Although the age gap between these two generation cohorts is not wide, the Generation X has distinctive purchase behaviors that are different from the Generation Y. In the fashion business, the Generation X consumers do not consider the brands in purchasing their clothes, but they calculate the benefits in buying a clothing product. However, the Generation Y consumers consider it as a part of their social status, therefore, they position themselves in the middle class or the upper class by what they wear. The aim of this research is to investigate the different purchase behaviors of the Generation X and Y in buying fast fashion products in Surabaya. The purchase behaviors are reflected through such variables as shopping orientation, status consumption, and impulse buying. As this is a quantitative research, the data are collected using questionnaires that are distributed to 100 respondents. The respondents are chosen using the purposive sampling technique. Then, the data are tested for the validity, reliability, normality, and homogeneity. To test the hypothesis, the independent samples t-test is used. The results show that the differences between the Generation X and the Generation Y are significant in their shopping orientation and impulse buying. However, there are no significant differences in the status consump-tions.
