Figure 5. Transition matrix between Leamer classes.

For each pair of classes it is measured how often an appearance event of a product from class is observed followed by a disappearance of a product from class , compared to the opposite direction. Rows are indexed by the appearing Leamer classes , columns by disappearing ones . A positive value indicates an excess in creative destruction processes between the two classes (from row index to column index). The matrix is by construction anti-symmetric. There is a clear tendency of appearing labor and capital intensive products, as well as machinery and chemicals. Cereals or agricultural products tend to disappear.
