THEORETICAL FRAMEWORK
The institutional framework for the analysis in this paper draws theoretically from the cross-disciplinary tools
that can describe the behavior of investors, the structure of financial contracts and institutions that bear risk and
manage uncertainty in project finance. In higher risk emerging markets, including Francophone West Africa,
investments in infrastructure by foreign direct investment (FDI) are made largely based on expected returns but
also based on perceived and actual risks which are related to the political, legal and the operational environment.
In this regard, there are three main theoretical bases underpinning the analysis adopted in this study: Transaction
Cost Economics (TCE); Institutional Theory (IT); and the Risk-Return Trade-Off Framework.
Transaction Cost Economics (TCE), as first articulated by Coase (1937) and refined by Williamson (1985),
offers a critical perspective to help explain how firms design their contracts and governance arrangements in the
presence of uncertainty and asset specificity. TCE assumes that firms bear costs when engaging in transactions
such as negotiation, monitoring, or enforcement costs of a contract. In places with poor institutional quality and
high risk, these costs are raised and conventional ways of funding infrastructure become unattractive. Project
financing, especially with supported by risk mitigation instruments, provides a way to alleviate these transaction
costs by placing risk where it will be most efficiently managed, routinely through the use of special purpose
vehicles (SPVs) and risk sharing arrangements. This theory provides a theoretical framework for deploying
structured and insured financial products—like guarantees and political risk insurance as mechanisms to address
information asymmetries and opportunistic behaviour that enhance the efficiency and financial sustainability of
infrastructure investments (see Yescombe, 2018; Estache & Wren-Lewis, 2021).
Institutional Theory adds to this understanding by focusing on the impact of formal and informal regulations,
standards, and enforcement on economic actions and organizational results. The attractiveness and success of
project finance and FDI in emerging markets from this point of view are not independent of the institutional
environment. North (1990, in particular, has claimed that institutions minimize uncertainty through creating an
order in which human interaction can take place, which is particularly important in markets with weak systems
of governance and weak regulatory reach. In Francophone West Africa, existence of Harmonized legislations
under OHADA, regional monetary institution as BCEAO and development finance institutions such as BOAD
and AfDB drive reductions in institutional voids. Nevertheless, differences in contract enforcement, political
stability, and administrative capabilities across countries continue to generate considerable variation in
investment conditions. Risk mitigation tools therefore will only be as successful as the institutions that support
the use and enforcement of these instruments as has been shown in recent research that links the quality of
institutions to the resilience of investment in UEMOA countries (Khan, Diop, & Sagna, 2024; AfDB, 2023).
The Risk-Return Trade-Off Framework elaborates the math behind investors math, i.e., scaling the desired rate
of return against different levels of risk. Based in modern portfolio theory and the classical financial economics,
this model posits that, in general, an investor would tend to invest only in those projects that offer a higher
return… for the additional risk encountered (Sharpe, 1964). In these markets, the risk premium is generally
higher than what institutional investors can bear, other than with risk mitigants such as guarantees, insurance or
concessional finance. So, risk mitigation instruments do not remove risk as such but change the risk-return
profile in favour of the investor, in view of attractive and bankable infrastructure projects. The model can explain
why even commercially-viable projects are unable to achieve financial close in the absence of the necessary de-
risking structures, and why blended finance solutions, combining concessional and market-based finance, are
gaining ground in fragile situations (Humphrey & Prizzon, 2022; OECD, 2023).
Collectively, these theories provide an integrated framework of the financial, institutional, and behavioral factors
that influence the outcomes of project finance under high risk conditions. Transaction Cost Economics offer an
explanation for the design of the architecture of project finance; Institutional Theory emphasizes the importance
of the institutional environment within which governance processes and regulatory systems were evolving; while
the Risk-Return Trade-Off-Framework explains investor decision-making in a value-of-risk (VOR)
environment. Considering the multifaceted character of the research problem, we use an integrated theoretical
approach, mainly based on Institutional Theory and Transaction Cost Economics as anchoring theories. These
two theories taken together help us in understanding the relationship between institutional quality, risk
management and investment behavior, and it thus presents a holistic framework on which we can build how risk
mitigation instruments affect FDI and project performance in the Francophone West African countries.
