• What is the difference between amortization and depreciating intangible asset? – Rudra Dec 30 '15 at 5:24
• I'm voting to close this question as off-topic because it's about accounting principles, not economic principles. This could be migrated to Personal Finance & Money – EnergyNumbers Dec 30 '15 at 6:48
• We should hash this out in economics-meta. There are numerous journal of economic literature (JEL) codes concerning accounting and accounting is often a class taught within the economics and business schools so while @EnergyNumber's position has some merit it isn't the only valid position. – BKay Dec 30 '15 at 14:29
• cc @Bkay Currently, Accounting is treated as off-topic in economics.se, economics.stackexchange.com/help/on-topic. But "Business Economics" are "on topic but". It is my impression, that a question like this one falls somewhere in between. – Alecos Papadopoulos Dec 30 '15 at 18:31
• Is this really an accounting question? Or is it on how to calibrate the depreciation rate $\delta$, given that intangible assets are more and more part of production? – FooBar Dec 31 '15 at 12:09
