Final answer:
The use of a periodic or perpetual inventory system affects cost allocations, with perpetual systems enabling more accurate, real-time data and cost formulas application, aligning with the budget constraint framework's focus on future events.
Step-by-step explanation:
The decision to use a periodic or perpetual inventory system has significant implications on cost allocations in businesses. A periodic inventory system calculates the cost of goods sold (COGS) at the end of each accounting period by conducting a physical inventory count, leading to less frequent updates and potential discrepancies due to shrinkage or errors. On the other hand, a perpetual inventory system keeps continuous track of inventory levels and cost of goods sold using technology, providing real-time data and more accurate cost allocations.
In a perpetual system, cost formulas such as First-In, First-Out (FIFO), Last-In, First-Out (LIFO), or Average Cost can be applied to each inventory transaction, leading to more precise cost allocations. This real-time approach aligns with the budget constraint framework, emphasizing that decisions are based on future events, and sunk costs should not influence current decisions. Contrastingly, a periodic system may result in cost allocations that are less reflective of current market conditions, as it is based on inventory levels at specific intervals.
In contrast, in a perpetual inventory system, the cost of inventory is continuously updated and the COGS can be determined on a real-time basis. This is because each time a product is sold, the inventory records are updated to reflect the cost of the sold item. As a result, cost allocations calculated using cost formulas in a perpetual inventory system are more accurate and up-to-date compared to a periodic inventory system.
