Costs, Prices and Inflation

Long-run historical series since 1270

Users should first consult the labour market and wages and prices section of Millennium of Macroeconomic Data v3.1 (xls) for long-run composite time series up to the present day.  These contain some of the data from the more detailed sources listed below.  Summary data from this spreadsheet are available for interactive viewing via FRED.

Medieval and early modern data

For detailed medieval data on English wages and prices users should consult the datasets of Professor Greg Clark of UC Davis and Professor Bob Allen of NYU Abu Dhabi.  These datasets can be found on Professor Clark's website and the Global Price and Income History Group website.  For additional evidence on the level of wages in the long C18th users should also consult the DPhil thesis of Judy Stephenson.

The Millennium of Macroeconomic Data v3.1 dataset contains wage and price indices from the late C17th but users should consult the following sections from the Gayer Rostow Schwartz microfiche for the period 1790-1850.

• Gayer, Rostow, Schwartz - Part III - Tables of Commodity Prices
• Gayer, Rostow, Schwartz - Part IV Section III - Commodity Price Series

Measures of comparative value

For measures of comparative value across time users should consult the Measuring Worth website curated by Professor Sam Williamson who provides various measures for the UK and other countries.

Consumer Prices - Methodology

The development of price indices is conventionally dated back to the C18th during which Carli and Dutot developed methods for constructing elementary unweighted price indices. Laspeyres and Paasche developed the theory behind weighted indices in the C19th based on using the available information in quantities and expenditure shares and to weight prices together. Fisher and Törnqvist in the C20th provided practical methods of approximating theoretically superlative indices as outlined by François Divisia. An NBER paper by Erwin Diewert provides an excellent guide to the early history of Price Index Research:

Several official consumer and retail price indices have been developed in the UK over the past century and a half using some mixture of these methods. Useful ONS documents

• Retail Prices 1914-1990

The Johnson Review from 2015 provides a summary of the modern thinking on price indices and the advantages and disadvantage of different methods and provided a set of recommendations on the way forward.

Further articles on methodlogical developments since then can be found on the ONS website.
