Abstract
Strike frequency is Britain's coal mining industry varied from a high of around 2200 strikes in 1957 to a low of about 100 in 1971 with a pronounced declining trend after 1958, due principally to the dramatic drop in mining employees from 700,000 to 300,000 in that same period. A model specifically designed for evaluating coal mining strikes is developed utilizing factors of: 1. employment, 2. prices, which include seasonal inflation, and 3. relative earnings. Employment in coal mining is directly tied to the retail price index, as well as to the other variables. Earlier research done by J. H. Pencavel had based analyses on a single equation developed to fit many different industries. Results of the 2 studies differed, indicating that explanations of strike activity may be more precise if a specific equation is developed to accommodate the particular characteristics of each industry.
