Analysis of the market for fianncial revision banking segment in the US

The sentence is to analyze the structure of auytors in the US market in the banking industry. We will use primary data from the article Staszkiewicz, P., & Karkowska, R. (2021). Audit fee and banks’ communication sentiment. Economic Research-Ekonomska Istraživanja. https://doi.org/10.1080/1331677X.2021.1985567 Data are as usual available from Niezbednik or distributed to you thourgh Teams (“Public Materials”) file named Bank.cvs. Please download to your own computer and upload it to R. Please note that the data can used after class for non-commercial purposes only, after indication of the original source.

# from the basic functions of the system we load a classic csv file but in such a way
# that we choose from a window the location of the file on our own computer 
# that's why we nest the "file.choose()" command

bank <-  read.csv(file.choose())

Let’s see the structure of the database you can do it from the “Environment” panel by clicking on the arrow next to the database name “bank” or by entering the command

Please note that before the variable name we have a dollar sign which allows us to refer to a variable in a given object in code r. e.g. bank$ROA refers to a column with information about the ratio of result to assets. As you can see above this solution is quite inconvenient why For visualization we rather use View function, which gives similar insight as in excel sheet.

View(bank)

We have about 5000 observations and 200 variables, in Excel processing such data will be cumbersome and difficult to audit, because Excel, apart from the “audit” function doesn’t leave an audit trail. Unlike Knit.

Problem 1

Which bank paid the most for the audit

#first we'll look at what was the highest salary in the base 
max(bank$Total_Fees_USDx)
## [1] 128000000
# the $ sign allows you to select a variable from the bank object

Given a value, we generate a name using the subset function and its parameter select (of course this can be done in many ways)

naj<-subset(bank,Total_Fees_USDx >= 128000000, select= Companyx)
naj
##                      Companyx
## 292 BANK OF AMERICA CORP /DE/

Task 1

Try to generate all the information that relates to the largest transaction

naj_all<-subset(bank,Total_Fees_USDx >= 128000000)
View(naj_all)

Now let’s see how many auditors (audit firms) served the banking market. For simplicity we will enter the result into the FA object and sorted in descending order, so that we know at once who has what market share in the market.

FA<-table(bank$Auditorx)
View(sort(FA,decreasing = TRUE))

And now we will make a third column that will show us the share percentage, namely

as.data.frame(FA) # sorting the vector was difficult we converted it to a frame

Task 2

Let us try to assess whether there are entities in the market whose audit firm’s remuneration is atypical.

Solution, we are looking for outliers, we will use the simplest mechanism of analysis i.e. a thumbnail plot

boxplot(bank$Total_Fees_USDx)

Not much is clear from this picture then let’s relate it to the total assets of a given enitity

boxplot(bank$Total_Fees_USDx/bank$Assets_USDx_N)

R as an environment has very good graphics capabilities and here is one example:

c<- bank$Total_Fees_USDx/bank$Assets_USDx_N
  c1<-c[c<max(c, na.rm= TRUE)]
boxplot(c1,
main = "Fee to total assets",
xlab = "",
ylab = "",
col = "orange",
border = "brown",
horizontal = TRUE,
notch = TRUE
)

We got rid of the largest observation for clarity, and arranged the image horizontally. More help(boxplot) options.

Finding this one entity is relatively easy.

Task 3

Please list the 6 entities with their CIK number, financial statement year, and company name that paid the most for auditing relative to total assets.

head(bank[order(bank$Total_Fees_USDx/bank$Assets_USDx_N,decreasing=TRUE),1:3])

Possible further analysis

Case studies from the Polish Kit (assignment book): 4.25 Information Supermarket 5.3 Traffic 5.4 Stranger Dance 7.3 - analysis at the level of bachelor’s, master’s, doctoral thesis

Additionally 1. the relationship between non-revision pay and opinion type 2. audit fees and performance management 3. audit firm specialization in the market

It is worth noting that analysis does not necessarily have to be advanced to generate the information needed in business.

For a doctoral-level research assignment, please try to replicate a study from an article on banks.
