company with financial performance that lies below
the industry performance tend to be more aggressive
in risky condition. Beside those two, many have been
examined the firm decision making under irrational
behaviour as posited by Prospect Theory (Sinha
(1994), Lehner (2000), Chou et al (2009), Kliger and
Tsur (2011), Dominguez and Raïs (2012), Diez-
Esteban et al (2017), Gupta and Pathak (2018))
Most of the result from prior studies show some
consistencies. Which led to the conclusion of many of
the sample performing loss-aversion attitude.
Kahneman and Tversky (1979) explained that there
two decision factors when certain individual attempt
to make a decision, especially if the result from the
decision they made is a risky one. First, the deciding
factor of decision making isn’t the amount of utility
or benefit that an individual will acquire. Instead, they
will compare the results or output from their decision
to the target level that already been decided
beforehand. In other words, they already have a
certain level of expectancy over future results.
Second, people have a tendency to avoid loss. It is
better not to lose $1 that to get $1. The level of
satisfaction from losing $1 will be different, if not
worse, than to find $1. Those two conditions explain
why loss-aversion happened, and also shed some
answer on why companies that underperformed tend
to be bolder, in term of making risky decision.
In short, the Prospect Theory explained the
decision-making behaviour of the firm in regard to
their risk preference. The risk-return relation will be
varied depending on firm performance position or
condition. The condition that mentioned in Prospect
Theory is winning or losing condition. The line that
separates those two conditions is called a reference
point. This reference point is so important, yet
Kahneman and Tversky (1979) in their paper did not
mention how the reference point is conducted. Thus,
such fact will be one of the obstacles for the
researcher to examine or testing the Prospect Theory.
Even though they did mention that to determine the
reference point, we must find the line that separate
gains and losses which in the end affecting the
decision maker.
Most of the prior research which examined the
relation of risk and return under Prospect Theory
usually measured the reference point at the industrial
level by using the centre value of firm performance.
We try to find the evidence that decision maker
within the firm which performed below (lose) the
reference level would show some risk-seeking
attitude, which will be proven by the negative
association between risk and return. While the firm
that able to perform better than peer company within
the industry (above the reference point) will show
risk-averse attitude.
2 METHOD
The data used in this research are all of the public
companies (ousting the financial industry) in
Indonesia from 2005-2012 and acquired from
Bloomberg database. We use all of the data from
those periods without omitting the firm that delisting
or recently being public in order to avoid the
survivorship bias. The sequence that we do before
testing the regression model is: First, we have to
determine the reference point. Using the reference
point method from Kliger and Tsur (2011), we
measure the reference point as the median of firms’
industrial return from the previous year (lag one
year).
Ref
i, j, t
= Med
j, t-1
Table 1: Descriptive statistics by Industry
Table 2: Descriptive Statistics for ROA as Alternative
Proxy by Industry
Ref
i, j, t
is the reference point within the industry
that calculated each year, and Med
j, t-1
median ROE
of industry j at year t-1. So even though we used the
data from 2004-2012, we only managed to get an
eight-year span of data. In order to find the reference
point, firstly, we separate our sample into industrial
subsample data. Then, we find the median ROE of the
previous year.
To test our hypothesis, we used a model that
shows the relationship between risk and return. The
basic model is in the following equation:
Risk
i, j, t
= α + β Dumwin
I, j, t
+ ε
i, t
Risk
i, j, t
= ROE
i, j, t
- Med
j, t
Where Risk
i, j, t
is calculated by finding the
difference between ROE
i, j, t
(ROE is calculated from
firm net income divided with total equity) and
