readFinancialCrisisFiles: banking crisis data and function to read financial crisis...

In Ecfun: Functions for Ecdat

Description

Read financial crisis data in files described by an object of class financialCrisisFiles. This is designed to read Excel files describing financial crises since 1800 downloaded from http://www.reinhartandrogoff.com/data/browse-by-topic/topics/7/.

bankingCrises is a data.frame created by readFinancialCrisisFiles() using 3 files downloaded from http://www.reinhartandrogoff.com and 1 obtained from Prof. Reinhart in January 2013.

Usage

readFinancialCrisisFiles(files, crisisType=7, ...)

Arguments

files	an object of class financialCrisisFiles.
crisisType	an integer (vector) between 1 and 8 indicating the type of data to be retrieved: 1=independence year (not a crisis but an indicator), 2=currency, 3=inflation, 4=stock market, 5=domestic soveregn debt crisis, 6=external sovereign debt crisis, 7=banking, 8=tally. ("Type" 1 = year.) These are all 0 or 1 indicating the presence of the event in the given year. Type 8 = sum of types 2 through 7.
...	arguments to pass with file and sheet name to read.xls when reading a sheet of an MS Excel file. This is assumed to be the same for all sheets of all files. If this is not the case, the resulting financialCrisisFiles object will have to be edited manually before using it to read the data.

Details

Reinhart and Rogoff (http://www.reinhartandrogoff.com) provide numerous data sets analyzed in their book, "This Time Is Different: Eight Centuries of Financial Folly". Of interest here are data on financial crises of various types for 70 countries spanning the years 1800 - 2010, downloadable from http://www.reinhartandrogoff.com/data/browse-by-topic/topics/7/.

The function financialCrisisFiles produces a list of class financialCrisisFiles describing different Excel files in very similar formats with one sheet per Country and a few extra descriptor sheets. The data object FinancialCrisisFiles is the default output of that function.

readFinancialCrisisFiles reads the sheets for the individual countries.

Value

If length(crisisType) == 1, a data.frame is returned with the first column being year, and with one other column containing the data for that crisisType for each country.

If length(crisisType) > 1, a list is returned containing a data.frame for each country.
