This unbalanced conversion was extremely favorable to flower agribusiness men who paid worker salaries, utilities, and other services in inexpensive sucres, but obtained high valued dollars from exporting their product. But this advantage was turned into a disadvantage when Ecuador decided to use dollars in national business contexts. The advantages that flower agribusiness enjoyed fueled a great development of this industry in Ecuador, which is now one of the four major world flower producers. But despite the economic boom of flower agribusiness, it is a very sensitive industry and has to face some drawbacks that could threaten its entire economic structure. The most critical threat that the flower industry must face is the end of the trade preferences under the ATPA, which could produce a contraction of the US market for the Ecuadorian roses that comprise 70% of total production. In the round of negotiations toward the free trade agreement that Ecuador has been discussing with the United States during 2004, some flower agribusinesses have raised concerns regarding the economic sustainability of the flower industry. The main issue that could constrain flower production is the expiration of the duty-free status in the United States on products imported from Ecuador and other Andean countries, which was scheduled for December 2001, but delayed due to a renewal approved in 2002. This renewal will last until 2005.5 If the duty-free status expires, it could result in disadvantageous trade conditions, not only for flowers but also for a whole range of commodities exported by Ecuador to the United States, including bananas, oil, minerals, and coffee. These concerns arose during the fourth round of negotiations toward the Free Trade Agreement between the United States and the Andean countries held in Puerto Rico during the second week of 5 The consensus to obtain a renewal of the ATPA in the US Congress was hard to reach due to debates on the damages caused by no tariff in local flower industry.
