A proper stock management in retail stores and in wholesalers is something that can play a major role in the development of a product category and in the whole economy in general.
Just imagine this: Many retailers find hard to sell the old and outdated models (bad stock) so that wholesalers have to wait before they launch the new updated models. This market is fallen far behind other economies which have moved forward 2 or 3 generations of the respective product category.
This issue (of stock management) is responsible for the delayed arrival of new products and models that are found in more economically advanced countries. It’s very common to have to wait many months for a new product that have just launched in the USA or other European countries to arrive in Greece!
