Roller Partners is a nationwide financial advising firm with managers assigned to each region. The partners are developing their sales budget for the following year. The central finance team, using econometric analysis, has set a sales budget for Region 5 of $13 million. Janet Smith, the Region 5 managing partner, has sent an email to the finance team that says, in part: The $13 million sales budget is unrealistic given some of the adverse local conditions. As you know, we have suffered two weather- related disasters as well as a fall in the prices for the local agricultural products.
