This file describes the program and data files for replicating the descriptive statistics and the estimation results in the paper
Please cite the above paper when using these programs.
Use the repository browser above to preview and download individual files, or download the entire folder as a single ZIP-file (588MB). If you have git, use
git clone https://github.com/korenmiklos/per-shipment-costs-replication.git
cd per-shipment-costs-replication
make
All programs are under folder code/. The following Stata do-files need to be run in sequence to replicate our results. The do-files have been tested on Stata 13.0 and should work across a variety of platforms with the exception of 02_dowload_data.do, which expects a Unix-like environment, such as Unix, Linux or Mac OS X. We have also included a makefile, so, in a Unix-like environment, you can just run make from the shell.
01_install_packages.doInstalls the necessary Stata packages. As with all other .do files, this should be run from the main replication folder asdo code/01_install_packages.do02_download_data.doDownloads all data from the available internet resources and saves them to the folderdata/. This script uses a Unix shell, so requires Unix, Linux or Mac OS X. If you are running Windows, check how to use zip and gzip from the command line. We have saved the output of this script indata/for your convenience, so you can skip the downloads.03_create_country_variables.doConverts the various datasets into Stata format and merges them. The output isdata/derived/merged_importer_data.dta.04_read_us_trade.doReads data from the monthly trade statistics published by the U.S. Census Bureau, merges with importer-country variables and reports shipment-level statistics. The output isdata/derived/usa_export_2009_with_gravity.dta.05_read_spanish_trade.doReads data from the shipment-level trade statistics published by the Agencia Tributaria, merges with importer-country variables and reports shipment-level statistics. The output isdata/derived/spain_export_2009_with_gravity.dta.06_descriptives.doCreates Table 1 in paper and correlation statistics for the Doing Business indicators.07_regressions.doRuns the estimations creating Tables 3-7. Output isexhibit/table*.xls.
All data are under folder data. Subfolders indicate the data sources.
census/trade/*/*.txt. We use the U.S. Foreign Trade Statistics reported by the Census Bureau for year 2009 on the most detailed level. The .txt files are copied from the DVDs. Please see https://www.census.gov/foreign-trade/reference/products/catalog/fl_exp.txt for a codebook.agenciatributaria/*.csv. The twelve files contain the shipment-level export data of Spain in 2009 by month. These data are reported by the Spanish Tax Authority (Agencia Tributaria) and are publicly available under http://www.agenciatributaria.es/.

The exhibits/ folder contains .txt and .xls files with Tables 3-7. These tables have been formatted for the paper. Please note that minor changes in some of the internet resources and rounding might cause small numerical discrepancies relative to the published tables. None of these discrepancies is substantial.
Trade agreements entering into force between 2005 and 2009. The EIA data is only up to 2005.
