In the old days of international trade, you were pretty happy when your customer asked you to quote for some product made in Germany, because you KNEW you would be cheaper.
Now it does not always work that way. I do have German customers getting better pricing from Northern China, alas not from me, but I also have German customers claiming they get better pricing from Germany! (This is in addition to American customers considering to have their production switched back to the US for sofas as the labor plus freight makes China pricy.)
Here's what I think happened:
1. Whatever is left being made in Germany now probably is being made by a very, very specialized firm that can be competitive.
2. Such firms can also make use of components made in Asia to lower their costs.
3. Meanwhile costs in Asia have risen, especially labor costs, but also raw materials and freight.
4. I probably have high overheads from having too many Taiwanese staff, but also maybe myself - its been on my mind that probably a Chinese person could do my job for me.
I suspect 2 & 3 are more important than 1 & 4.
So, it might be that days of cheap labor arbitrage are over - and that is a good thing for the world in general. But that won't pay my bills, so my customers keep asking about Vietnam, Thailand, Indonesia, etc., imagining there is still some room for cheap labor arbitrage. Well, there might be some room there, but mathematically it won't be much:
German labor is US$ 30 / hour.
China labor is US$ 5 / hour
Vietnamese labor is US$ 3 / hour
(These are all just made up.)
So, taking something that takes one hour made in Germany and having it made in China saves US$ 25.00.*
Now let's say you have a product being made in China and you want to move it to Vietnam. Will you save a lot of money? You only save US$ 2.00. And if Vietnam has any other costs that are higher than China's - say importing raw materials, lower productivity than China's, then you might save NOTHING.
And, importantly, if you are outsourcing the product instead of making it yourself, if the supplier knows the price in China, they could simply undercut by the smallest amount that makes you move your orders, say 10% or US$ 0.50.
So it seems to me that the days of labor arbitrage are becoming more limited, though people are now moving their wood factories to Cambodia and farther afield - which again should eventually lead to higher wages their and more economic convergence.
And that is a good thing. Just like today's rising food costs, if they do represent people eating better in China and India - well, that's a good thing right?
*Note that wages reflect productivity so its not really so clear you would capture all of the savings. If the labor market were completely competitive and we ceteris paribus product's labor intensiveness, management skill, capital available, etc. then making the product should actually cost the same in every country. But if that were the case no one would invest in China except perhaps for the local market. The idea of investing in low wage countries is that you can achieve some sort of advantage by using their cheap labor more efficiently and use the increased productivity to offer a better price.
