R-Code: Generation of SPEI data and estimation of drought effects on feed prices in South Germany
Code as a research output can either be uploaded directly from your computer or through the code management system GitHub. Versioning of code repositories is supported.
We provide here the R-code for the complete replication of Schaub and Finger (2019a). The code allows to i) download weather data from the German Meteorological Office, ii) extract weather information for the agricultural area of Germany, iii) compute the Standardized Precipitation Evapotranspiration Index (SPEI), iv) to estimate an SVAR model and v) to replicate figures and tables presented in Schaub and Finger (2019a). The code is structured into 1) a master file (‘r_master_script_feed_price_paper.R’), 2) a file for weather data preparation (‘r_weather_script_feed_price_paper.R’) and 3) a file for data preparation, estimation and visualization of results (‘r_estimation_script_feed_price_paper.R’). Please follow instructions in the master file when executing the code. The data for the replication can be found at Schaub and Finger (2019b).
