Download and Process Damodaran Industry Data

Description

Downloads industry averages from Aswath Damodaran's data library. Currently, the cost of capital (WACC) by industry is supported via dataset = "wacc". The source files are Excel workbooks, so the function requires the readxl package.

Usage

download_data_damodaran(dataset = "wacc", region = "us", year = NULL)

Arguments

dataset	The dataset to download. Currently only "wacc".
region	A character vector of regions: "us" (the default), "europe", "japan", "emerging", "global", "china", "india", or "rest" (Australia, New Zealand, and Canada).
year	Optional. An integer vector of years. If not provided, the most recent data is returned. Years that are not available are skipped with a warning.

Details

Damodaran updates the data each January with the data at the end of the previous year. The year column refers to that previous year, e.g., the file published in January 2026 has year = 2025. Earlier years are read from the archive of the data library. The archive starts in 1998 for the US, in 2013 for Europe, Japan, emerging markets, global, China, and India, and in 2015 for Australia, New Zealand, and Canada. China and India skip some years.

Value

A tibble with one row per region, year, and industry and the columns region, year, industry, number_of_firms, beta, cost_of_equity, equity_to_capital (E/(D+E)), sd_stock (standard deviation of stock returns), cost_of_debt, tax_rate, after_tax_cost_of_debt, debt_to_capital (D/(D+E)), wacc (cost of capital in US dollars), and wacc_local (cost of capital in local currency, NA where the source file does not provide it). Rates are decimals. The rows "Total Market" and, in recent files, "Total Market (without financials)" hold the market-wide averages.
