Measuring Economic Change with Index Numbers

Understanding how prices change over time is crucial for making informed economic decisions, but the underlying statistics can be complex. This course demystifies the theory and calculation behind key economic indicators. By the end of this course, you will have a solid foundational understanding of how index numbers are constructed and applied, allowing you to confidently analyze economic data related to inflation, production, and cost of living. What you'll learn: * Understand the core concepts, terminology, and historical context of index numbers, including base periods and weighting schemes. * Calculate simple price relatives and aggregate index numbers using classical methods like Laspeyres, Paasche, and Fisher's Ideal Index. * Analyze the structure and purpose of major economic indicators like the Consumer Price Index (CPI) and Wholesale Price Index (WPI). * Apply index numbers to measure inflation rates, determine real wages, and adjust economic data for purchasing power parity. * Practice interpreting index number data series to identify current trends in economic growth and cost of living changes. We begin with fundamental definitions and the principles of data collection, moving methodically through calculation formulas and practical examples. The material focuses on applying these statistical tools to real-world economic scenarios. This course is designed for absolute beginners in economics, finance, and statistics.
