Trust as a Factor in B2C eCommerce

• The Theory of Reasoned Action (TRA) of Ajzen & Fishbein (1980) postulates that Trust is a major determinant of attitude towards purchasing, and hence of intention to purchase

• In Internet-based B2C eCommerce, Trust is usefully defined as:

confident reliance by Consumers about the behaviour of relevant Business Enterprises

Personal Data Privacy and Consumers

• Consumer Expectations• Privacy is a 'fundamental human right'• Excited by abuses, and numbed by them• Excited by advocates and the media

• Particularly Serious Concerns• Consumer behaviour data• Anti-discrimination categories • Taxation and financial data• Health data• Household data• Location data for persons-at-risk

Objectives of the PIA Process• Clearly define:

• business needs• stakeholder groups• privacy impacts

and implications• Enable understanding

and assessment of the proposal

• Enable mutual understanding of stakeholder perspectives

• Ensure reflection of stakeholder perspectives in the outcomes

• Enable:• maximisation of positive

impacts• avoidance or amelioration

of negative impacts• Maximise the likelihood of

stakeholder support• Avoid new requirements

emerging late• Earn public confidence• Raise awareness, educate • Anticipate and avoid

misinformation campaigns

Privacy Impact Assessment (PIA)

A sophisticated process that surfaces and examines potential impacts and

implicationsof privacy-invasive proposals

A primitive form of unilateral reportby an organisation

about what the organisation does with personal data

Alternative Regulatory Approaches

to Privacy Protection

• ‘Hard’ RegulationStatutory Impositions, Criminal Prosecution

• Self-Regulation“Wolves self-regulate for the good ofthemselves and the pack, not the deer”

No country accepts self-regulation alone, except the U.S.A.

• ‘Co-Regulation’Education, Changes to Procedures, Complaints Processes,Back-Ended by Damages Provisions and Criminal Sanctions

The Role of PPS in the Alternative Regulatory Contexts

• ‘Hard’ RegulationLittle or no real role

• Self-RegulationThe key feature that is meant to create the impressionthat consumers have some kind of protection

• ‘Co-Regulation’Possible role, as an adjunct to minimum requirementsor as a means of interpreting the law

The Research Question

• 'How effective are Privacy Policy Statements in encouraging consumer trust of B2C vendors?’

• Operational Formulation:

'Do the Privacy Policy Statements found on vendors' web-sites measure up to the requirements expressed in a specific normative Privacy Statement Template'?

Privacy Policy Statement Template

http://www.anu.edu.au/people/Roger.Clarke/DV/SPT.html

• Comprehensive• Based on consumer need and practicality• Not constrained by:

• OECD Gs’ 1970s View of Technology• Business-Bias of the US ‘Safe Harbor’

• Designed to provide guidance for all, includingcorporations, business associations, govt agencies,individuals, public interest reps and advocates

Population Segmentation

Dimension 1 – The Business

• ‘Pure Internet B2C’• ‘Clicks-and-Mortar’

Dimension 2 – The Company

• Leaders• Aggressive Marketers• Marketers of Sensitive

Products• Regional Marketers• ‘Ethical’ Marketers /

‘Not-For-Profits’

Sample for the Pilot Survey

Leaders:• Amazon• GoogleAggressive

Marketers:• Sears, Roebuck &

Co.Marketers of

Sensitive Products:• Adultshop.com

Regional Marketers:• Autoteile-Meile.de

(German online supplier of tyres and automotive spare parts)

Procedure• Determine the segmentation• Determine the sampling frames• Determine the sample• Conduct the assessment

• find the organisation’s web-site• find the PPS on that web-site• assess it against the template• summarise• compare among the sample• draw inferences

Results

• Google terrible• Amazon worse• Sears & Roebuck worse again• Adultshop.com positive• National Geographic appalling• Autoteile-Meile Google-like and

irrelevant

Implications for Practice

Caution: very limited external validity!

• Descriptive value:Many PPS are valueless to consumers

• Explanatory value:Current PPS undermine consumer Trust

• Predictive value:Fragility if and when things go wrong

• Self-Regulation doesn’t work‘Hard’ or ‘Co-Regulation’ is essential

Implications for Research• Segmentation needs refinement:

• Organisational Size is a factor• Home Jurisdiction cf. Global

• The Normative Template needs refinement• The design appears to be:

• Practicable• Useful

• A representative sample can be assessed,and results capable of being generalised from can be achieved, with limited resources
