An article in the Wall Street Journal (August 11, 2012) describes how legal copying, permitted in fashion apparel, financial instruments, food etc, help those industries. By speeding up adoption of new ideas and designs, these industries benefit from the buzz or trends, and create a desire to move to the next trend, thus generating continued demand. In addition, many of the customers who buy copies of a product, trade up to buy the original product later, thus generating demand for the original designer. Which industries should push to promote legal copying, given such benefits ? Should the differing intellectual property protection across countries be treated as a reflection of individual country preferences for such industry benefits ? When can this go too far, and stifle the incentive for innovation ?
