  • What are economic scenario generators?

    An Economic Scenario Generator (ESG) refers to a mathematical model (and its computer implementation) that simulates possible future paths of economic and financial market variables.
  • What are scenarios in economics?

    Economic scenario planning gives corporate leaders a way to model their businesses for success, despite the uncertain extremes of the current economic moment. It achieves this goal by combining multiple sources of data, including external macroeconomic data sets, econometric modeling, and economic expertise.
  • The formula for the dynamic mean reversion point has been defined by the NAIC as follows: Mean reversion point = 20% of the median over the last 600 months + 30% of the average over the last 120 months + 50% of the average over the last 36 months The result is then rounded to the nearest 0.25%.
