A case study focuses on a single individual, a small group of people, or occasionally a single event. You'll be conducting qualitative research to find specific details and descriptions of how your subject is affected. 1  For example, a medical case study might study how a single patient is affected by an injury.ou may be asked to prove that the case study does no harm to its participants. 1  Follow this step even if you are conducting a retrospective case study. 2  In some cases, publishing a new interpretation can cause harm to the participants in the original study.
Formula or Equation Note. The incremental capital output ratio (ICOR) is defined as the ratio between investment in some previous period(s) and the growth in output in the subsequent period.Needless to say, ICOR calculation is based on constant price data.ormula or Equation Note.

3. The marginal product of capital (MPK) is the output produced per unit of additional capital. The MPK can be shown graphically using the production function. For a fixed level of labor, plot the output provided by different levels of capital; this is the production function.The MPK is just the slope of the production function. production function shows how much output can be produced with a given amount of capital and labor. The production function can shift due to supply shocks, which affect overall productivity. Examples include changes in energy supplies, technological breakthroughs, and management practices.
