Commodities, Global Value Chains, and Governance

Defining Commodities: Beyond Price Homogeneity

Substantial literature exists on commodities, their relationship with trade and development, and the organization of their production processes, yet scholars have not reached clear consensus on what a commodity actually is. A commodity could be simply defined as any kind of good produced to be exchanged in the market rather than for personal use. Daviron and Ponte (2005) define commodities as 'goods with a world market where most participants and transactors use the same global quality standard to discover the same measurable quality attributes'. Bernstein (2006a) notes that Daviron and Ponte's elaborations on the features of commodities address more the symbolic value of highly differentiated products that reach consumerist society and less the producer and intermediate goods themselves.

This study distances itself from definitions such as that of Gordon et al. (1999), which claim that in the context of food and agricultural industries the term refers to products whose price is determined by a specific set of characteristics that make them homogenous. According to this view, profitability can increase through marketing and promotion—that is, through product differentiation, market segmentation, and niche markets, products can become non-commodities. This represents the recently widespread, and rather misleading, idea that de-commoditization is possible through product differentiation. Such a definition fails to point out that nothing is intrinsically a commodity (Nevins and Peluso 2008). Rather, it is the process through which value and property rights are assigned to a product that results in commoditization.

A more nuanced understanding recognizes that commodities are not fixed categories but relational designations shaped by institutions, markets, and power. This approach aligns with broader Marxist traditions that emphasize commodity production as a social process rather than a mere technical or market classification. The significance of this distinction becomes clear when examining how certification, marketing, and standardization operate not as means of escaping commodity status but as mechanisms through which commodification itself is actively produced and maintained.

Commodity Fetishization and Hidden Relations

An often-disregarded characteristic of commodities, rescued by Hartwick (1998) through a reading of Marx, is their direct link to specific contexts, conditions of production, and power relations that are frequently hidden from final consumers through a process called 'commodity fetishization'. This concept reveals how the market exchange of commodities masks the social and environmental costs embedded in their production. Daviron and Ponte acknowledge a process of double fetishization in which the masking of the social relations of production is combined with the commoditization of sustainability and certification in the coffee sector, which often fail to deliver desired benefits for small producers.

Bernstein (2006b) regards this analysis as adding new nuances to Marx's original concept rather than departing from it, as some authors suggest. Most importantly, he notes that 'the physical, market or cultural/symbolic value of goods and services does not remove them from the domain of commodity production in the Marxist sense'. In other words, the adoption of sustainability labels, fair-trade certification, or product differentiation does not exempt these goods from the fundamental dynamics of commodification and value extraction. These mechanisms instead become new layers through which exploitation and unequal exchange can operate. Understanding commodity fetishization is therefore essential to any analysis that seeks to expose the hidden labor, environmental damage, and power asymmetries contained within global commodity chains.

Global Value Chain Framework Origins

The Global Value Chain (GVC) framework is based on the work of Gereffi and Korzeniewics (1994) and is described as a methodology for studying global economic governance. It has been used across disciplines within the social sciences interested in the international organization of industries in different sectors. According to Ponte, Gibbon and Bair (2008), three main approaches to GVC have emerged through the years: governance as driving, governance as coordination, and governance as normalization.

The first approach, originally known as Global Commodity Chain Analysis (GCC), is rooted in Hopkins and Wallerstein's (1986) world-system theory and their concern for the global division of labour. GCC addressed the way in which inter-organizational networks around a certain commodity interact in the world economy through three key dimensions: (1) the input-output structure and geographical coverage; (2) the internal governance structure (entry barriers and chain coordination); and (3) the institutional framework—that is, how local, national, and international policies shape the way actors interact in a globalized context (Daviron 2002).

GCC analysis distinguished between two main types of governance structures. Producer-driven chains are more typical of capital-intensive industries in which producers tend to retain control of operations. Buyer-driven chains are more typical of labour-intensive sectors where actors in charge of marketing, design, and retailing are the ones setting entry barriers and determining value distribution (Bair 2008). This distinction proved foundational for understanding how power asymmetries become embedded in different types of commodity networks.

Governance as Coordination and Structure

In recent years, the term GCC has been abandoned in the literature and substituted by that of GVC, which focuses more on the conceptualization of governance as coordination. Gereffi, Humphrey and Sturgeon (2005) suggest that the structure of global value chains depends upon three main variables: (a) the complexity of transactions; (b) the ability to codify transactions; and (c) the capabilities in the supply-base. Based on these variables, they outline five possible categories of governance: market, modular, relational, captive, and hierarchy.

This framework represents a shift from earlier GCC analysis by emphasizing the mechanisms through which lead firms coordinate and control value chains without necessarily owning assets directly. Market governance occurs when transactions are relatively simple and suppliers are easily replaceable. At the opposite end of the spectrum, hierarchy describes situations where lead firms own and directly control suppliers. The intermediate categories—modular, relational, and captive—describe different degrees of interdependence, mutual adjustment, and asymmetric dependence between buyers and suppliers.

The five-category model provides analytical tools for identifying how information flows, standards, and monitoring mechanisms enable coordination across geographically dispersed production networks. However, this focus on transactional coordination has been criticized for bracketing out the broader normative, cultural, and historical contexts within which value chains operate. Despite these limitations, the GVC governance framework has become influential across development studies, international political economy, and business studies.
