An industry is the manufacturing of a good or service within a category, industry is a broad term for any kind of economic production, in economics and urban planning industry is a synonym for the secondary sector, which is a type of economic activity involved in the manufacturing of raw materials into goods and products.
There are four key industrial economic sectors the primary sector, largely raw material extraction industries such as mining and farming, the secondary sector, involving refining, construction, and manufacturing the tertiary sector, which deals with services and distribution of manufactured goods, and the quaternary sector, design and development such as computer programming, and biochemistry.
A fifth quinary sector has been proposed encompassing nonprofit activities. The economy is also broadly separated into public sector and private sector, with industry generally categorized as private. Industries are also any business or manufacturing.
Previous research has found evidence that wages in industries characterized as high tech, or subject to higher rates of technological change, are higher. There is evidence that skill biased technological change is responsible for the dramatic increase in the earnings of more educated workers relative to less educated workers that took place during the 1980s.
In this paper, a variety of industry level measures of technological change to a panel of young workers observed between 1979 and 1993 and examine the role played by unobserved heterogeneity in explaining the positive relationships between technological change and wages, and between technological change and the education premium.
Evidence that the wage premium associated with technological change is primarily due to the sorting of better workers into those industries. In addition, the education premium associated with technological change is found to be the result of an increase in demand for the innate ability or other observable characteristics of more educated workers.
Years after its formation, the Florida Citrus Exchange continued to initiate sweeping changes within the industry, such as improved shipping methods and marketing on an international scale.
