4.1. Results of Logistic Regression Analysis Based on Respondents’ Survey
The overall number of answers received from the residents of the Baltic States was 1030, however, some of them were removed from further analysis according to the inappropriate filling in the questionnaire (e.g. the questionnaire was incomplete or the respondent marked he did not use Internet banking). Hence, the number of respondents in the researched countries was as follows: In Lithuania—342; in Latvia—351; in Estonia—320. The minimum size of samples for each country was calculated using Equation (1) and reached 271 respondents. In the current study, the sample size of each country was higher, which demonstrated that the results represented the whole country’s population.
Respondents had to fill in a questionnaire and assess the most important factors for them.
The study was conducted in cyberspace using the website
www.manoapklausa.lt [
64], developed by “Solid Data”, UAB. Actually, as the research was done online, there was a limitation—the results could be applied only to internet users.
While analysing trust in internet banking (Y), respondents were asked to evaluate the influence of the following factors on their trust:
- -
Provided information, X1
- -
E-banking system, X2
- -
Website of a bank, X3
- -
The bank’s characteristics, X4.
For the purpose of assessment of individual customers’ trust in internet banking, logistic regression was used. The respondents’ age was selected as a categorical variable. Overall, 87% of the participants in Lithuania in the cross-validation group were correctly classified; in Latvia, this number reached 84.1%, whereas in Estonia 86.3%. Nagelkerke pseudo-R
2 in Lithuania, Latvia, and Estonia was 0.291, 0.518, and 0.243, respectively. All the values were greater than 0.15, which means that the model is acceptable and could explain populations’ intentions on whether to trust internet banking. The model’s
in Lithuania was 63.145, in Latvia 149.684, and in Estonia 49.491, which means that in all the cases,
satisfied the condition
p < 0.01. What is more, according to the Wald test, statistically insignificant variables were removed from the analysis. They were as follows: X
2 (e-banking system), X
3 (website of a bank) in Lithuania; X
1 (provided information) in Latvia; and X
1 (provided information), X
2 (e-banking system), X
3 (website of a bank) in Estonia. The not mentioned variables satisfied the Wald criterion and were used for the logistic regression models’ development (see
Table 3).
As was mentioned above, the respondents’ age was selected as a categorical variable (Xcat) that could gain a value of 0 and 1 (0 means that the respondent is 35 years old or younger, 1 means that the respondent is older than 35 years old). From Equation developed for Lithuania, it could be seen that in the case of Lithuania, the greater the values of regressors X1 (provided information) and X4 (the bank’s characteristics) were, the higher the probability that individual customer trusts/will trust internet banking. In other words, the more transparent, qualitative, and reliable the provided information is, the higher the level of characteristics of a bank, such as its image and reputation, and the higher individual clients’ trust in internet banking in Lithuania. The odds ratio estimates and their 90% confidence level are as follows: For the regressor X1 (provided information) 0.066 ([0.04; 1.160]) and for the regressor X4 (the bank’s characteristics) 0.103 ([0.10; 1.055]). According to Equation developed for Latvia’s residents, it could be claimed that e-banking system, the website of a bank, and the characteristics of a bank are the factors that enhance the probability of individual customers’ trust in internet banking in Latvia. The odds ratio estimates and their 90% confidence levels were as follows: For the regressor X2 (e-banking system) 0.157 ([0.43; 0.578]), for the regressor X3 (website of a bank) 0.075 ([0.15; 0375]), and for the regressor X4 (the bank’s characteristics) 0.228 ([0.056; 0.924]). Analysing Equation designed using Estonia’s respondents’ answers, it became clear that the characteristics of a bank are the only factors that help to increase the probability of trust in internet banking. The odds ratio estimates and their 90% confidence levels were as follows: For the regressor X1 (provided information) 0.146 ([0.070; 0.305]).
4.2. Results of AHP Analysis Based on Expert Evaluation
In order to calculate the weights of the selected factors and subfactors influencing individual customers’ trust in internet banking, seven experts from each country were selected. All the experts held PhD degrees in economics/management/finance and had at least three years working experience in the field of banking. Information about the experts is presented in
Table 4.
It is worth mentioning that the competence coefficient was calculated for all the experts (see
Appendix A). All the results fell into the interval
, where s varies between 0.003 and 0.005 for the countries analysed. Hence, it could be stated that there were no outliers in the experts’ answers and all the results might be used for the trust in internet banking factors and their subfactor prioritisation. Moreover, the results of Cronbach’s alpha indicate a high level of consistency (Cronbach’s α = 0.783). Consequently, the weight of each alternative could be calculated.
Since the weights of each alternative/factor were computed, the most vital factor was identified.
Experts assessed four determinants of individuals’ trust in internet banking: Information; the bank; website; e-banking system.
Studying Lithuania’s, Latvia’s, and Estonia’s experts‘ pairwise comparison matrices, it became obvious that the matrices of the experts coded ETLT3 and ETEE2 were inconsistent and before aggregating the final result matrices, they were modified into consistent ones using Method-S, presented in the Methodology section. Other experts’ matrices met the condition CR < 0.2 and did not need modifications.
Lithuanian and Latvian experts highlighted the electronic banking system as a factor having the greatest impact on the confidence in internet banking (see
Table 5). The bank site ranked first, while the e-banking system remained the second according to Estonian experts. However, the difference between these factors is minimal, so it can be said that they are almost equivalent.
In the theoretical part, subfactors were identified for each factor of confidence in internet banking. Experts also assessed them. The analysis of Lithuanian experts’ subfactors pairwise comparison matrices revealed that the individual matrix compatibility ratio of experts coded ET
LV1,3, ET
EE5 was greater than 0.2, so it can be said that the matrix was inconsistent and before the overall assessment needed to be harmonised. Other experts’ pairwise comparison matrices compatibility indices were in line with the initial condition, i.e., CR < 0.2. The compatibility ratio and lambda (λ) complied with the conditions laid down, so it can be concluded that the experts’ evaluation is accurate (see
Table 5). In addition, the consensus (agreement) index was greater than 80 per cent in all the investigated countries (see
Table 5). Thus, as can be seen from
Table 5, the criteria used to assess the accuracy of experts’ opinions is satisfied; therefore, it can be said that the weights given by experts are significant. The weights and ranks of subfactors are presented in
Table 6.
Lithuanian, Latvian, and Estonian experts’ opinions on the most important subfactors of information are the same (see
Table 6). Baltic experts agreed that reliability is the most important subfactor, and experts of all the countries ranked it as the first and gave it greater than 0.36 weight.
Lithuanian and Latvian experts considered the quality of information as the next major factor. Estonian experts ranked quality third. According to them, information transparency is a more important factor. In fact, quality and transparency can be synonyms: In the absence of transparency, information may not be of good quality.
Six subfactors of a bank’s characteristics factor were analysed. They are as follows: Competence, integrity, goodwill, shared values, reputation, and image. All experts’ individual comparison matrices satisfied the compatibility condition and, therefore, did not require modification. The compatibility ratio and lambda (λ) met the conditions set (see
Table 7). It can be concluded that the aggregate experts’ assessments may be used in the general summary of results. The consensus index was greater than 80 per cent in all the analysed countries (see
Table 7). The criteria used for the assessment of expert opinions were satisfied, making it possible to analyse the weights assigned to aggregated subfactors (see
Table 7).
Lithuanian and Estonian experts agreed that the main subfactor of a bank’s characteristics is the bank’s reputation (see
Table 7). Undoubtedly, reputation is a factor that can help to achieve higher profitability because with a good reputation, commercial banks can attract more customers. Customers who chose a bank based on its reputation feel greater confidence in the bank; hence, reputation directly promotes consumer confidence in banking services growth. In addition, Lithuanian and Estonian experts deemed integrity an important subfactor. It is a commercial bank interest in the client’s well-being. Commercial banks are interested in making the appropriate environment because only in this case will users feel comfortable and trust the growth. Unlike Lithuanian and Estonian experts, Latvian experts provided the second position for reputation, and the fourth position for integrity and the first place gave for competence. Undoubtedly, service staff competence is essential in solving everyday customer problems associated with internet banking. Thus, competence as integrity is important to create the proper environment for users; however, Lithuanian and Estonian experts’ assessment was similar, and they only gave the fourth position to competence. Baltic experts ranked the image of a commercial bank third. Actually, the image gives organisations such as commercial banks a competitive advantage in an environment where any other organisations offering similar services as commercial banks act.
While analysing banks’ websites, three subfactors were distinguished: A website‘s security, privacy, and fairness. The aggregated matrix satisfied all the conditions; hence, it could be used in order to analyse the aggregated weights of the subfactors.
The consensus index was greater than 74 per cent for all the examined countries (see
Table 8).
Experts from all Baltic countries agreed that security is the most important subfactor concerning websites (see
Table 8). Security is associated with the technical aspects of internet use, such as the technically safe use of the website, password security, information storage, etc. Experts ranked privacy second. Individual customers understand privacy as an opportunity to use online bank services confidentially, i.e., not disclosing, for instance, payment history or the amount of money on the account to third parties. Thus, security and privacy are concepts, adjacent to each other, which could be seen from the ranks designated by experts. Fairness was ranked third. Actually, customers can only feel secure when the bank is fair to its consumers. What is more, privacy cannot be reached without fairness, because the client ought to be assured of the bank’s fairness. In other words, the bank could make its clients feel secure and private only if it is fair.
Examining e-banking system factors, four subfactors were picked: Ease of use, perceived benefits, satisfaction with the system, and internal motivation of the customer. After analysing pairwise comparison matrices, the aggregated matrix was developed, where the consistency ratio and lambda (λ) met the conditions (see
Table 9), meaning that the experts’ evaluations were accurate. What is more, the consensus index was higher than 68% in all three countries.
Experts from Lithuania and Latvia ranked perceived usefulness first (see
Table 9). In reality, customers should fully understand e-banking systems’ benefits, such as time-saving, management of personal finances, etc. Estonian experts ranked ease of use first and perceived benefits second, while Lithuanian and Latvian experts considered ease of use second. In fact, the differences between the weights of first and second positions are minor; hence, it could be stated that these two subfactors are the most important in e-banking trust formation.
The tables presented above (see
Table 6,
Table 7,
Table 8 and
Table 9) provide the local weights of the subfactors. The global values of the subfactors ought to be calculated in order to estimate the impact of each subfactor on trust in internet banking. The subfactors’ local weights should be multiplied by the weight of the corresponding factor to get global values. The global weights of the subfactors are presented in the table below (see
Table 10).
The most important factors, determining customer trust in online banking in Lithuania, are security (0.98); information reliability (0.96); perceived usefulness of the e-banking system (0.95); and ease of use of the e-banking system (0.94) (see
Table 10). Latvian experts set the maximum weight for security at 0.123; for fairness second at 0.121; privacy and perceived usefulness of the e-banking system according to experts from Latvia are nonetheless important, as their weights were 0.110 and 0.105, respectively. According to Estonian experts, security was also ranked high and prioritised, and its weight reached 0.141; fairness and ease of use of the e-banking system second and third, respectively (0.115 and 0.102), and perceived usefulness of the e-banking system forth (0.098).
Lithuanian experts’ opinion on the fairness differed from Latvian and Estonian experts‘ point of view. Results showed that in the case of Latvia and Estonia, fairness was one of the key subfactors affecting individual clients’ trust in internet banking, while Lithuanian experts did not give this subfactor such importance. Information reliability was less critical for Latvian than for Lithuanian and Estonian experts. What is more, privacy was a much more important subfactor for Latvian than for Lithuanian and Estonian experts. Nevertheless, experts from all countries assessed security as the most important subfactor.
Taking into consideration the overall results of the resident and expert surveys, banks’ decision-makers should note the following:
- -
In Latvia, the e-banking system and website are the most important;
- -
In Lithuania, the opinion of residents and exporters differs; thus, it is important to reflect on information, the bank, and the e-banking system;
- -
Estonian residents and experts also highlighted different criteria—the bank, website, and e-banking system;
For the facilitation and improvement of these factors, the following measures are significant:
- -
In Latvia, for the development of the e-banking system, perceived usefulness is the most important and for the promotion of the website, security;
- -
In Lithuania, the reliability of information, reputation of the bank, and perceived usefulness of the e-banking system should be inspiring;
- -
In Estonia, it is important to stress on the reputation of the bank, security of the website, and the ease of use of the e-banking system.
This research provides a meaningful conceptual contribution and offers important and influential practical insights. The first one includes a complex multidimensional criterion of trust. The testing of the highlighted factors allows to ascertain the most important factors in all analysed countries. Notwithstanding the fact that the history and mentality of all three Baltic States seems to be similar, the results differed. In addition, in all three countries, the same Scandinavian banks own the largest market share. Consequently, practical insights will guide decision-makers as to which particular elements of fair treatment have the most significant impact on trust in internet banking.
