today 73 economies have single window systems of varying complexity. exporting and importing a standardized cargo container is faster in such economies. In addition,fewer documents are required for important, but the impact is smaller than the impact on time-an average of 6.6 documents in economies with single window systems compared with 7.8 in those without-underscoring the point that single window systems are mainly making submission of information more efficient.Using a single window to lodge information can even fight corruption by reducing interactions between traders and authorities.And it can make the clearance process more predictable and enhance transparency. Among the 73 economies with single window systems,86% make information on duties and tariffs publicly available, while only 54% of the other 110 economies measured by Doing Business do so.
Though a single window system brings considerable gains,implementation is a major undertaking involving many stakeholders and requiring long-term commitment from multiple players in government and business.Implementation takes many years and might have to be done in phases. Though their overarching goals are the same,single window systems differ greatly, highlighting the need to adapt them to each economy-taking into account the computerization of users, internet connectivity and the capacity of implementing bodies.
This case study describes the experiences of Singapore became one of the fist economics to embrace the single window concept, and it has evolved into a highly integrated virtual system, recognized as global good price. Colombia and Azerbaijan. In the late 1980s Singapore became one of the first economics to embrace the single window concept, and it has evolved into a highly integrated virtual system, recognized as global good practice. Colombia is single window was launched in 2005 and has also developed in stages. Today the system links 21 trade entities and is continuously adapting its system to make things more efficient for traders and government. Azerbaijan is single window is the newest covered in this chapter and provides a revealing contrast to Singapore is mature system. Azerbaijan launched its system in 2009 and so is still in the government is leveraging its position as a latecomer by learning from other economies.By choosing 3 economies in different regions with different degrees of single window implementation, this case study aims to show the various approaches that governments take and the challenges encountered of pursuing effective single windows. The case study does not aim to promote a particular type of single window system nor endorse the experiences of these economies.
