level of infrastructure and trade openness are one of the major determinants

of long run economic growth. Financial literacy has potential to affect the

economic growth by making contribution to the savings and development of

financial sector. In this study, the impact of Usak University staff’s financial

Introduction

The factors such as capital stock, human capital, technological progress,

financial development, institutional development, infrastructure

development level and trade openness have been asserted as the major

determinants of long run economic growth (e.g. see Solow, 1956; Lucas,

1988; Romer, 1986 and 1990; King and Levine, 1993; Aghion and Howitt,

1998). The national savings have potential to affect the economic growth

positively by contributing to the capital accumulation directly and making a

contribution to the other determinants of economic growth such as

technological progress, financial development, and infrastructural

development indirectly. The savings were about 25% of global GDP in the

world and this ratio was about 15% in Turkey (World Bank, 2016). So the

savings fail to satisfy the financing of the investments in Turkey and the

savings gap in question is financed by foreign capital to a large extent.

Nowadays financial markets have been developed quickly with the

contribution of financial liberalization and globalization and a wide range of

alternative instruments of financial services and new saving instruments

have been discovered. Theoretically, a developed financial sector can

enhance the savings by raising the efficiency of the financial intermediation

and presenting more savings vehicles (e.g. see King and Levine, 1993; Levine,

1997; Dudian and Popa, 2013). However, the positive effect of financial sector

development on the savings partially depends on the financial literacy of the

individuals. Therefore, the fact that financial literacy fell behind financial

sector development led the contraction in the effect of financial sector

development on the savings in some countries such as Turkey.

Furthermore, financial literacy is important for the development of

financial system, because the individuals who are at both fund supplier and

demander of the financial system. Hence, Jappelli and Padula (2011) revealed

that countries with higher financial literacy level had relatively higher

savings and a 1 unit standard deviation increase in financial literacy led a 3.6

points increases in the national savings. Therefore, many countries,

especially the United States and European Union countries, are trying to

improve financial literacy by lowering financial education to the level of

primary education and by organizing various programs for adults. The

financial literacy level was relatively lower when compared with OECD. The

2014 Financial Literacy and Inclusion Index calculated by the Economy Bank

of Turkey and Bogazici University indicated that financial literacy level was

59.4 (OECD average was 63) and financial inclusion index was 39.17. So both

financial literacy level and financial inclusion was relatively lower in Turkey.

The objective of the paper is to analyze the effect of financial literacy and

demographic variables on the personal savings by logistic regression

analysis. In this regard, there have been a limited number of studies

investigating the interaction between financial literacy and personal savings

in the relevant literature. So this study will be an early paper which

researches the relationship for Turkey. However, the findings of the study

will be important for financial education planning and determination of

saving incentive policies. The second section of the paper summarizes the

relevant literature, and Section 3 presents data and method. The descriptive

and logistic regression analyses and major findings are presented in Section

4. The study is over with Section 5.

Literature review

Financial literacy is important at micro and macro level especially for

households, financial system, national economy and monetary policy.

Financial literacy directs the individuals and households to make the

budgeting right and savings, conduct their assets and debts well, and use

their savings in a reasonable way in the financial market. Increasing

financial inclusion leads the increases in the liquidity, trading size, and

financial product range in the financial markets and in turn makes a

contribution to the development of the financial system. Furthermore,

financial literacy contributes to the households and small and medium

sized enterprises to make their financial planning better. As a consequence,

this improvements causes the increases in the stability and efficiency of

financial sector. However, informed customers make a contribution to the

financial institutions’ working in a more reliable, reasonable, and efficient

through affecting the behaviors of the financial institutions. So financial

literacy encourages the individuals and households to use their money more

reasonable and make savings at micro level. Also financial literacy

contributes to the economic growth through affecting the development of

financial sector quantitatively and qualitatively. The expanding economy in

turn makes contribution to the increases in national savings, financial

development, and decreases in the unemployment and improvements in

living standards.

A wide range of empirical studies have been conducted on personal

savings and financial literacy measurement separately. The studies generally

have focused on the determinants of saving and financial literacy

measurement of a sample (e.g. see Kessler et al., 1993; Berube and Cote,

2000; Swasdpeera and Pandey, 2012; Aren and Dinç-Aydemir, 2014; Sarıgül,

2014; Özdemir et al., 2015; Baysa and Karaca, 2016; Şamiloğlu et al., 2016).

However, a limited number of studies analyzed the effect of financial literacy

on savings and mostly revealed that financial literacy positively affected the

savings (Lusardi, 2008; Beckmann, 2013; Mahdzan and Tabiani, 2013; Jappelli

and Padula, 2013; Murendo and Mutsonziwa, 2017).

In one of the studies, Prusty (2011) examined the saving behaviors

and financial literacy level of the househoulds for a sample of 3500 persons

at 50-55 age range from working population in India and found that

financial literacy was a significant determinant of household saving. In

another study, Mahdzan and Tabiani (2013) analyzed the effect of financial

literacy on the personal savings in a sample of 192 persons from master of

business administration program students of Malaya University and Klang

valley residents with probit regression and discovered that financial literacy

was a significant positive determinant of personal savings. Jappelli and

Padula (2013) also developed an intertemporal consumption model about

the investments in financial literacy and examined the effect of financial

literacy on wealth and savings in a sample of 50 and over aged population

and revealed that financial literacy raised the savings.

In another study, Beckmann (2013) researched the effect of financial

literacy on household saving with regression analysis and discovered that

financial literacy affected the savings positively. Jamal et al. (2015) analyzed

the interaction between financial literacy and savings in a sample of 1124

high school and undergraduate students from Sabah state of Malaysia

structural equation modeling and found that financial literacy was a

significant determinant of savings.

In another study, Hidajat (2015) analyzed the effect of financial

literacy on savings for a 258 fishermen in Indonesia and revealed that

financial literacy was a significant component of savings. Barış (2016)

analyzed the financial literacy level and budgeting behavior in a sample of

359 students from Gaziosmanpasa University Faculty of Economics and

Administrative Sciences in Turkey and found that there was no significant

relationship between financial literacy and budgeting. Finally, Murendo and

Mutsonziwa (2017) researched the effect of financial literacy on personal

saving decisions in a sample of 400 persons from Zimbabwe with probit

regression analysis and revealed a positive relationship between financial

literacy and personal savings.

Data and Method

Data

The sample of the study composed of Usak University personnel and the

dataset was obtained by the questionnaire in the Annex. In this context, 910

questionnaires were delivered and 350 of the questionnaires were able to

receive from the subjects. However, 325 (92% of them) questionnaires were

found to be complete and useable. Therefore, the response rate was 35.71%.

In the study, personal saving was represented by SAVING variable.

SAVING variable was a binary variable and 1 value indicates the positive

savings by the subjects, while 0 value indicates that the subjects made no

savings. In this context, we asked the subjects about their income and

expenditures. If the expenditures were equal or higher than the income,

SAVING variable was coded as 0. On the other side, SAVING variable was

coded as 1 in case the expenditures were lower than the income. Financial

literacy (FINLIT) variable was measured by the questionnaire prepared in

the light of Lusardi (2008) and Lusardi and Mitchell (2007a, 2007b, 2008).

First basic financial literacy and advanced financial literacy of the

individuals were determined, then general financial literacy level was

calculated by adding up basic and advanced financial literacy levels. Basic

financial literacy was calculated by 4 questions about interest calculation,

inflation and risk diversification. Advanced financial literacy was measured

by 9 questions about stocks, mutual funds, and bonds. The right answers

were coded as 1, while the wrong answers were coded as 0. Therefore,

general financial literacy level takes a score between 0 and 13 and higher

score means higher financial literacy level.

Method

This study researches the effect of financial literacy and demographic

variables on personal saving. The logistic regression analysis is used, because

the dependent variable (SAVING) is a binary variable.

𝑆𝐴𝑉𝐼𝑁𝐺 = 𝛼 + 𝛽1 ∗ 𝐹𝐼𝑁𝐿𝐼𝑇 + 𝛽2 ∗ 𝑅𝐼𝑆𝐾𝑇𝑂𝐿 + 𝛽3 ∗ 𝐺𝐸𝑁𝐷 + 𝛽4 ∗ 𝐴𝐺𝐸 + 𝛽5

∗ 𝐸𝐷𝑈𝐶𝐷𝐸𝑃 + 𝜀 (1)

In the (1) numbered equation, 𝛼 is the constant term, 𝛽𝑛 are the

estimated coefficients, 𝜀 is error term.

It is expected that financial literacy affects the personal savings. The

improvements in financial literacy enable the individuals to make more

informed decisions about money and saving allocation. On the other side,

the individuals with higher risk tolerance tend to make less savings (Zhong

and Xiao, 1995).

Furthermore, the empirical studies indicated that men generally

make more savings and also women have relatively lower financial literacy

when compared with the men (e.g. see Lusardi and Mitchell, 2007). On the

other side, as people get older, the people have an interest in pension period

and age (AGE) variable is expected to affect the personal savings positively,

because the old have relatively lower lifecycle expenditures such as

educational, marriage and household expenses (Mahdzan and Tabiani, 2013).

The number of children (CHILD) is expected to affect the personal savings

positively due to the sensitiveness about children’s future. Also working

experience (WORK) variable is expected to affect the personal savings

positively, because people make more financial decisions during their

working period and in turn have more saving consciousness.

The economic theories, ceteris paribus, also suggest that income

(INCOME) variable affects the personal savings positively. Finally, education

level (EDUC) variable is expected to affect the personal savings positively,

because people with higher education level can understand the financial

issues better and therefore make better financing decisions and plan their

futures better.

Empirical Analysis

Reliability Analysis

SPSS 22.0 software package was used for the econometric analysis of the

study and the significance level was taken as 5% for all the analyses.

Cronbach alpha, split-half reliability, parallel forms reliability and strict

parallel reliability are major reliability tests in the literature. The value of

Cronbach alpha should be higher than 60% (some researchers suggest that

Cronbach alpha should be higher than 75%) for the reliability of the

questionnaire. Also the other criteria should be higher than 70% for internal

consistency of the questionnaire and the reliability of the inferences.

Cronbach alpha, split, parallel and strict reliability tests were used to

examine the reliability of questionnaires and the results were displayed in

Table 2. Each of the reliability criteria was found to be higher than 70%. So

the questionnaire had internal consistency and the results were reliable.

in the question investigating about the financial asset which provides

relatively higher return in the long run. The second lowest correct answer

ratio with 29.85 was seen in the question investigating the relationship

between interest rate and bond price. Furthermore, about 30% of the

participants answered the questions about mutual funds correctly. However,

about half of the participants answered the questions about stock market

In the study, total financial literacy was calculated by sum of basic

and advance financial literacy levels and presented in Table 9. The basic

financial literacy of the participants was 3.35 out of 4 as seen in Table 9. Soo

the participants had a good knowledge about interest rate, inflation and

percentage calculate. However, the advanced financial literacy level of the

participants was 3.89 out of 9. Therefore, the participants had a medium

level of advanced financial literacy. Furthermore total financial literacy of

the participants was 7.24 out of 13. The increases in total financial literacy

score partially resulted from high basic financial literacy scores.

Logistic Regression Analysis

The effect of financial literacy, risk tolerance, gender, age, the number of

children, and term of employment, income level, education level, and

education department on personal savings was analyzed with logistic

regression and the results were displayed in Table 10. The logistic regression

model was found to be significant in the light of results of Omnibus test (chi

square value=467.099 (P value=0.001)). Step-by-step forecasting process was

followed in the estimation of logistic regression and the significance level of

the models was raised by -2 log likelihood=645.172 value reaching the

highest value and Cox & Snell R Square= 0.634 and Nagelkerke R Square =

0.603 value reaching lowest value. Hosmer and Lemeshow test investigating

the compliance of the model was found to be a 4.739 chi square (p

value=0.342). Therefore, we could no reject the null hypothesis stating that

the model was suitable and the model was found to be suitable for the

analysis.

The estimated coefficients of the logistic regression indicated that

the number of children, term of employment and undergraduate and

graduate department did not have a significant effect on the personal

savings. However, risk tolerance affected the personal savings negatively,

but financial literacy, age, gender, income level and education level affected

the personal savings positively. Income level, financial literacy, risk

tolerance, age, education level, and gender had respectively highest effect on

the personal savings.

Conclusions

Financial development and savings are the ones among the major

determinants of economic growth in the context of the endogenous and

exogenous growth theories. Therefore, the factors encouraging the financial

development and savings have potential to make a contribution to the

economic growth indirectly. Financial literacy may affect the economic

growth through raising the savings and development of financial sector.

Raising financial inclusion of the individuals and households contribute to

the increasing liquidity, transaction size, and product range of financial

system and development of financial sector. Furthermore, financial literacy

contributes to the households and small and medium sized enterprises to

make better financial planning. As a consequence, emergent stability and

efficiency may lead the improvements in stability and efficiency of financial

system. However, informed customers can raise the market discipline, in

other words cause the financial institutions to function more reliable,

reasonable and efficient, through affecting the behaviors of financial

institutions.

Financial literacy also causes the individuals and households to

spend their money shrewder and encourage making savings. Also a relatively

better financial literacy can contribute to the individuals and households’

reaching their financial goals such as buying a house, financing the

children's education expenditures and a better retirement experience.

Impact of Financial Literacy on Personal Savings: A Research on Usak University Staff

Vol. VII, Issue 6 December 2017

This study researched the effect of financial literacy and

demographic variables on the personal savings in a sample of Usak

University personnel with logistic regression analysis. The estimated

coefficients indicated that the number of children, term of employment, and

undergraduate or graduate department had no significant effects of personal

savings. However, financial literacy, age, income level, and education level

had a positive effect on the personal savings, while risk tolerance affected

the personal savings negatively. Furthermore, income level and financial

literacy respectively had the highest impact on the personal savings.

Consequently, we discovered that financial literacy had positive

impact on personal savings in consistent with theoretical expectations and

empirical findings. In this regard, financial literacy has potential to

contribute to the savings through affecting the economic growth by

financial development. So the policymakers should consider that the

measures enhancing the financial literacy have potential to make to

contributions to the individuals at micro level and the whole economy at

macro level.
