Valuing Processes

Conventional economic theory assumes that people care only about ultimate outcomes and are indifferent to the decision and allocation processes by which outcomes are brought about. Building on Sen (1997), I relax this assumption, and investigate the formal and philosophical issues that arise. I extend the formal apparatus of preference theory to analyse how processes may enter preferences, and investigate whether traditional invariance requirements like the Weak Axiom of Revealed Preference are still satisfied in this new setting. I show that it is, provided certain conditions of separability hold, and I discuss the plausibility of these conditions. Further, I argue that processes are often valued in a mode that diverges from the conventional modes of instrumental and intrinsic/independent valuation. I introduce the notion of dependent non-instrumental valuation, and show how processes could depend on their instrumental function for their value – making their value dependent – and yet derive their value from something else – making it non-instrumental. Dependent non-instrumental value, I argue, can be explained by symbolic and evidential relations between processes and outcomes.
