Well, I'm not an economist, but clearly gain in productivity does not automatically equal increasing cash! BTW: same thing with profits. Profits do not automatically equal cash. In fact it's very easy for a company to have rising productivity and rising profit but to be losing cash.
Can you name some of the easy ways in which a company can be gaining in profits and have no cash? Where to the profits go (and how does “competition” make that happen? If you are saying that they immediately plow it into capital investment, you probably have evidence for why you think that?
Because it is my understanding that if you put _executive_ pay on that graph, you can immediately see where the profits are going.
That's a very good question that even a lot of finance people don't understand. The difference between profit and cash is time. A dollar profit equals a dollar in the future. The problem is that companies often will stretch the time when they receive the cash. The disruptions are mostly caused by changes in payables and receivables and growth. For example: if a company is profitable but their customers start slow paying them, cash is slowed down. Early in my career I had a customer who was willing to allow us to increase our prices to him (increasing profit), in exchange for longer receivable terms (wanted to pay us net 45 days). Not receiving the cash for 45 days almost put us out of business because our normal expenses had to be paid - despite how much longer it took to get the cash. The turn on receivables has a huge impact on cash flow. Sometimes a company's vendors will demand quicker payment - that will drain cash. Other issues that affect cash: inventory write-downs, receivable write-downs, equipment purchases, and etc. Secondly, as companies grow - their profit cycle (when they get cash) is stretched. However, their expenses don't stretch. I have payroll at my company every week. I pay most of our expenses either weekly or monthly. As we grow, it creates a longer cycle to realize the cash needed to pay the fixed expenses.
Secondly, I think that some of the profit to owners stats are skewed because of pass-through entities. I'm a partial owner of an S-corp. I'm paid a wage. But all the yearly profits from the company flow to my (and my partners) personal tax returns. On our tax returns, it appears that we are taking huge profits. But we aren't. We actually only take as much profit (distributions) that we need to pay the increased personal taxes that result from the company profit. We retain all excess profits to the company. Our company is growing fast and is always short on cash. We would retain more, if we could. So, on paper, it would appear that all our profits are going to the owners. Does that make sense?
