The paper intends to examine the effects of attitudes towards business ethics of traders in their business decisions. Primary data were collected through a questionnaire, with 108 sole-trading retail businesses from Biratnagar city, Nepal, purposively. The results show that attitudes towards business ethics significantly affect traders’ business decisions. As the attitudes towards business ethics incline to positivity, the ethicality of business decisions hikes up. Similarly, traders’ socio-demographic characteristics (gender, academic qualifications, and their years in business) have a monumental impact on their business decisions. Women traders are comparatively more ethical than their counterparts. Higher education of traders is associated with progressive ethical practices in business. As the traders grow older in their venture, their ethicality in business operations is likely to expand. The study concludes that traders believe in running their business ethically, because ethical dealings in business activities lead to long-term benefits in terms of subsistence and success.
