A 1997 analysis of density forecasts of inflation made in the SPF finds: "The probability of a large negative inflation shock is generally overestimated, and in more recent years the probability of a large shock of either sign is overestimated. Inflation surprises are serially correlated, although agents eventually adapt.
The detailed prices used to compute PPPs are based on data published by the World Bank as part of the International Comparison Program (ICP). An empirical finding documented extensively by PWT is the Penn effect , the finding that real GDP is substantially understated when using exchange rates instead of PPPs in comparing GDP across countries.
Real GDP is an example of the distinction between real and nominal values in economics.Nominal gross domestic product is defined as the market value of all final goods produced in a geographical region, usually a country; this depends on the quantities of goods and services produced, and their respective prices.
A working paper by Robert J. Hodrick titled "An Exploration of Trend-Cycle Decomposition Methodologies in Simulated Data" [10] examines whether the proposed alternative approach of James D. Hamilton is actually better than the HP filter at extracting the cyclical component of several simulated time series calibrated to approximate U.S. real GDP ...
A chained volume series is a series of economic data (such as GDP, GNP or similar kinds of data) from successive years, put in real (or constant, i.e. inflation- and deflation-adjusted) terms by computing the aggregate value of the measure (e.g. GDP or GNP) for each year using the prices of the preceding year, and then 'chain linking' the data together to obtain a time-series of figures from ...
The following list includes the annual nominal gross domestic product for each of the 50 U.S. states and the national capital of Washington, D.C. and the GDP change and GDP per capita as of 2024. [1] [3] The total for the United States in this table excludes U.S. territories. The raw GDP data below is measured in millions of U.S. Dollars.
Blue Chip Economic Indicators is a monthly survey and associated publication by Wolters Kluwer collecting macroeconomic forecasts related to the economy of the United States. [1] The survey polls America's top business economists, collecting their forecasts of U.S. economic growth, inflation, interest rates, and a host of other critical ...
Economic data are data describing an actual economy, past or present.These are typically found in time-series form, that is, covering more than one time period (say the monthly unemployment rate for the last five years) or in cross-sectional data in one time period (say for consumption and income levels for sample households).
