Answer:
Scholarly
Step-by-step explanation:
A scholarly magazine is characterized as the type of magazines that are authored by professionals or experts in a specific field or discipline. Such magazines are considered an authentic source of information for various studies or further researches as it offers first-hand data or information without having any chances of bias, prejudice, or falsity.
In this question, the magazine titled 'The American economic review' would be considered a 'scholarly magazine' as it offers peer-reviewed articles in the discipline of economics and it considers only articles that are authentic and first-hand and prepared by the experts/professionals with appropriate referencing. Thus, it justifies the above definition and is truly a 'scholarly' magazine.
