The authors Ha and Swales (2012) attempt to determine the single-region IO analysis of a stylized export-base model. They found that improvements in value-added efficiencies also improve upon the GNP of countries and the labor market. There were also regional improvements in exportation which helped to sustain growth.
Exports are the underpinning of strong economic activity. The export-base model is a simplified version of the Keynesian demand-driven approach whereby exports and regional productivity are linked. As market demand increases so does the need to produce more products for export. This in turn can increase economic activity to meet market demands.
Generally, when policy makers want to increase exports in the export-based model they introduce and spend money on the port and other export functionality. It is hoped that by reducing the costs through investments that it will make exportation cheaper and encourage more use of the facilities. This has a positive effect but can be limited if the internal regional mechanics are not improved for greater competition.
Exports have an impact on the region. Furthermore, they can also influence surrounding areas that contribute to the exportation of products. There is a separation between domestic production and export production. Export production being that which is sold to other markets while domestic production serves the needs of locals. At times these are blended together because they relate to each other.
Increases in efficiency also increase other areas of the sector. There is a cross-breeding that creates higher levels of adaptation within the market. In turn, increased value-added efficiencies also improved the Scottish Gross National Product. As companies produced more efficient products that were demand laden in the market the wealth of the region increased.
Improvements in the exporting of products are also not the only benefit. The local economy also improves through growth within the labor market. The fundamental aspects of the economy improve through the creation of stronger efficiencies, value-added products, improved exportation, and general employment opportunities.
To further the reports findings, GNP improvements can be fostered through improvements such as deep sea ports that help to create efficiencies in exportation. Yet, in alignment with the report, true improvement is outside massive spending and instead lies in the efficient development of new products and services that improve upon market principles. These improvements enhance the labor market, bring more relevant products to the international market, and create stronger regional growth. Through rejuvenated products and services comes growth.
The simple Keynesian model used to do similar analysis is as follows:
X-M=Exports minus Imports.
In the model when a shock has occurred government can increase spending to improve other areas. The problem with prolonged government spending is that it throws the equilibrium out of balance as that spending must either be paid for by increasing taxes or increasing debt. It is better, at least in the long-run, to improve upon the market principles of creating more relevant value-laden products and services for exportation. Improved exportation improves upon the fundamentals of the local economy, improves labor opportunities, increases tax revenues through expanded economic activity, and develop higher levels of sustainable growth. Where government does wish to spur activities it should focus on those areas where it improves upon efficiency for multiple industries such as ports, collaborative development, infrastructure, improved market information, market hubs, drawing foreign investment, educational improvements for labor/innovation development, etc. It is important to remember that government spending and influence should be to improve upon the economic fundamentals and the environment versus short-term purchasing of inefficient economic activity.
