Gross domestic product (GDP) is the monetary value of all the finished goods and services produced within a country's borders in a specific time period.
Recent survey findings from RetailMeNot show that this season's wedding guests plan to spend $195 on a sibling's wedding gift, $159 on a best friend, $63 on a coworker and $45 on an acquaintance.
