As introduced by [9], the Ricardian Hypothesis states that as firms are endowed with different production-
investment opportunity sets, then the managers’ inventory accounting choice can be predicted by the comparative
advantage in tax cost minimization associated with the production-investment opportunity set of each
firm. IFRS (International Financial Reporting Standards) allows only cost method to be used to calculate the inventory valuation while mark-down is prohibited. Such regulation implies that companies with large inventory
price fluctuations may have advantage in adopting FIFO while companies with steady inventory price may prefer
to use LIFO.
