Research

Methods

Research Methods

• Research methods are split broadly into quantitative and

qualitative methods

• Which you choose will depend on

• your research questions

• your underlying philosophy of research

• your preferences and skills

14

Choosing your approach

• Your approach may be influenced by your colleagues’ views, your organisation’s approach, your

supervisor’s beliefs, and your own experience

• There is no right or wrong answer to choosing your research methods

• Whatever approach you choose for your research, you need to consider five questions:

• What is the unit of analysis? For example, country, company or individual.

• Are you relying on universal theory or local knowledge? i.e. will your results be generalisable, and

produce universally applicable results, or are there local factors that will affect your results?

• Will theory or data come first? Should you read the literature first, and then develop your theory, or will

you gather your data and develop your theory from that? (N.B. this will likely be an iterative process)

• Will your study be cross-sectional or longitudinal (time series)? Are you looking at one point in time, or

changes over time?

• Will you verify or falsify a theory? You cannot conclusively prove any theory; the best that you can do is

find nothing that disproves it. It is therefore easier to formulate a theory that you can try to disprove,

because you only need one ‘wrong’ answer to do so.

15

Quantitative Approaches

• Attempts to explain phenomena by collecting and analysing numerical data

• Tells you if there is a “difference” but not necessarily why

• Data collected are always numerical and analysed using statistical methods

• Variables are controlled as much as possible to eliminate interference and measure the

effect of any change

• Randomisation to reduce subjective bias

• If there are no numbers involved, its not quantitative

16

Quantitative Data

• Data sources include:

• Surveys where there are a

large number of respondents

• Observations (counts of

numbers and/or coding data

into numbers) – i.e. no

respondents

• Secondary data (economic /

financial market data)

• Analysis techniques include

hypothesis testing,

correlation, regression

analysis, etc

17

Falsifiability

Are they different????

• Falsifiability or refutability

of a statement, hypothesis,

or theory is the inherent

possibility that it can be

proven false

• Hypothesis testing

• Start with null hypothesis

i.e. H0 – that there will be no

difference

18

Analysing Quantitative Data

• Always good to group and/or visualise the data initially ->

outliers/cleaning data

• What quantity are you looking for?

Mean, median or mode?

• Spread of data:

• skewness/distribution

• range, variance and standard deviation

19

What are you looking for?

• Trying to find the signal from the noise

• Generally, either a difference (between/within groups) or a

correlation

• Choosing the right test to use:

parametric vs non-parametric (depends what sort of data you

have – interval/ratio vs nominal/ordinal and how it is distributed)

• Correlation does not imply causation!

20

Does correlation always tell the truth?

21

Identification Strategy

• We want to tell more about a relationship than merely:

• x is associated with y

• a is related to b

• To establish a plausible causality (i.e. x caused y)

• More to be covered in Lectures 6 and 7

22

Theoretical Research

• Normative theory

• A type of theory that focuses on what should be or what ought to be, rather than what is. It's about setting standards, values, or

goals.

• Descriptive statement: "People in Italy generally eat a Mediterranean diet.“ This is fact

• Normative statement: "People in Italy should eat a Mediterranean diet because it is healthier.“ This expresses an opinion about what people ought to do

• Theories about how economies should be managed to achieve certain goals, such as economic growth or social justice.

• Positive theory

• A type of theory that focuses on what is or what exists in the real world. It's about describing, explaining, and predicting

phenomena without making judgments about whether they are good or bad.

• Descriptive statement (also Positive statement): "People in Italy generally eat a Mediterranean diet.“

• Positive statement: "People who eat a Mediterranean diet tend to have lower rates of heart disease."

• Other examples include MM irrelevance theorems, capital asset pricing model (CAPM), accounting valuation models, option

pricing theory, agency theory

• Interpretive/critical theory

• Primarily concerned with developing understanding through observing aspects of behaviour, practices and technologies

• This leads to interpretive frameworks for understanding how accounting and finance function in organisations and society

23

Empirical Research

• Empirical research builds our understanding through empirical evidence

• Empirical research largely builds on positive and interpretive/critical

theoretical perspectives

• Positive approach is most prevalent in empirical research in financial

reporting and financial management where researchers test hypotheses

related to theoretical models

• Interpretive / critical approach is more prevalent in management accounting

where researchers are concerned with the organisational functioning of

accounting practices

• Research on governance and accountability includes different approaches,

some studies adopt more positivist approach, others are more interpretive /

contextual

24

Issues in Finance and Accounting

• Our focus in this module is on questions and issues addressed in the empirical research

literature

• A wide variety of research questions or issues are addressed in this literature

• Some questions / issues may be closely related to predictions of particular positive theories

or models

• Other questions may be more open-ended and seek to understand how techniques and

information are used by capital market and organizational participants

• Note also an increasing tendency for research questions to be related to issues of current

economic, social and regulatory importance

25

Examples of research questions

• Does the capital market make use of accounting information to value shares and has

the introduction of IFRS improved the quality of accounting information?

• What is the relative usefulness of different types of accounting information (e.g.,

earnings v cash flow information) to investors?

• Are fund managers able to generate abnormal stock returns (i.e. returns above the

‘required’ rate of return)?

• How important is corporate governance information to the analysis and

recommendations of financial analysts?

• What is the relationship between ESG performance and firm value? To what extent

does ESG performance influence firm valuation?
