AB purpose : considering THE_INCREASING_IMPACT of ARTIFICIAL_INTELLIGENCE ( AI
   ) on FINANCIAL_TECHNOLOGY ( FINTECH ) , THE_PURPOSE of THIS_PAPER is to
   propose A_RESEARCH_FRAMEWORK to better understand ROBO_ADVISOR_ADOPTION by
   A_WIDE_RANGE of POTENTIAL_CUSTOMERS . it also predicts that
   PERSONAL_AND_SOCIODEMOGRAPHIC_VARIABLES ( FAMILIARITY with ROBOTS , AGE ,
   GENDER and COUNTRY ) moderate THE_MAIN_RELATIONSHIPS .
   DESIGN_METHODOLOGY_APPROACH : DATA from A_WEB_SURVEY of 765 north american ,
   british and PORTUGUESE_POTENTIAL_USERS of ROBO_ADVISOR_SERVICES confirm
   THE_VALIDITY of THE_MEASUREMENT_SCALES and provide THE_INPUT for
   STRUCTURAL_EQUATION_MODELING and MULTISAMPLE_ANALYSES of THE_HYPOTHESES .
   FINDINGS : CONSUMERS_ATTITUDES toward ROBO_ADVISORS , together_with
   MASS_MEDIA and INTERPERSONAL_SUBJECTIVE_NORMS , are found to be
   THE_KEY_DETERMINANTS of ADOPTION . THE_INFLUENCES of PERCEIVED_USEFULNESS
   and ATTITUDE are slightly higher for USERS with A_HIGHER_LEVEL of
   FAMILIARITY with ROBOTS . in_turn , SUBJECTIVE_NORMS are significantly more
   relevant for USERS with A_LOWER_FAMILIARITY and for CUSTOMERS from
   ANGLO_SAXON_COUNTRIES . PRACTICAL_IMPLICATIONS : BANKS and OTHER_FIRMS in
   THE_FINANCE_INDUSTRY should DESIGN_ROBO_ADVISORS to be used by
   A_WIDE_SPECTRUM of CONSUMERS . MARKETING_TACTICS applied should consider
   THE_CUSTOMER_LEVEL of FAMILIARITY with ROBOTS . ORIGINALITY_VALUE :
   THIS_RESEARCH identifies THE_KEY_DRIVERS of ROBO_ADVISOR_ADOPTION and
   THE_MODERATING_EFFECT of PERSONAL_AND_SOCIODEMOGRAPHIC_VARIABLES . it
   contributes to UNDERSTANDING_CONSUMERS_PERCEPTIONS regarding
   THE_INTRODUCTION of AI in FINTECH . 2019 , EMERALD_PUBLISHING limited .
