Abstract:
Commodity reference price (CRP) is potentially an important commodity price
management influencing factor. However, despite its importance, it remains
under-researched and poorly understood. Anchored in contingency theory and
building on previous studies, this study (a) conceptualizes CRP contingency as
CRP transparency, (b) creates a CRP transparency index as a tool for classifying
and evaluating CRP, and (c) demonstrates the CRP transparency impact on CRP
functions and CPM practices.
Intuitive and interpretive literature reviews are combined with nine directed expert
interviews to uncover the CRP transparency attributes. Subsequently, 111
interviews with purchasing managers explore a purposive sample of 22 CRP to
construct and populate the CRP transparency index and to explore its theoretical
and practical relevance, in particular, how individual CRP transparency levels
shape CRP functions and impact the availability, choice and performance of
commodity price management practices.
The main contributions of this thesis to theory are (a) conceptualizing CRP
transparency as a multi-dimensional construct composed of four measured
attributes: accuracy, completeness, publication frequency, and methodology, (b)
operationalizing these measured attributes into five transparency levels, (c)
constructing CRP transparency index divided into five distinct and meaningful
levels following a geological metaphor: black hole, opaque, translucent,
transparent, dazzle. From a practitioner standpoint, this thesis provides
actionable insights into (i) CRP transparency assessment and comparison with
alternative CRP, (ii) how CRP transparency shapes the commodity price
management practices and CRP functions and, (iii) offers an empirical toolbox
for assessing, comparing, and configuring CRP to regulators and CRP issuers.
