This work proposes to restate the theory of surpluses by taking into account observed situations of the creation and liberation of surpluses which clearly break the rules and norms of accepted rationality. It presents a general theory which incorporates these situations which are not accepted within the classical hypotheses.

This theoretical framework incorporates psychological time in the analysis of surpluses and of the resulting equilibrium in the wake of Walras, Dupuit, Pareto, Marshall, Hicks and Allais. The concept of substitution, together with the resulting dynamic of the marginal rate of substitution, are redefined on the basis of the specific referential of a psychological nature, which constitutes the economic Subject and its action, and is structured by duration, memory and forgetfulness. Although we appear to be substituting goods, quantities and physical matter – and this is often the case – it is always a question of substituting time, value-times, matter-time, units of memory and duration.

The work thus proposes an HRSLR approach (Hereditary, Relative, Subjective and of Limited Rationality hypothesis) to the “consumer” demand function. We define the notion of a fundamental price on the basis of the relationship between the instantaneous price and the perceived psychological value-time. We posit an analogy between (i) marginal rates of substitution; (ii) marginal rates of increase or slowdown in the perceived psychological value-times; and (iii) marginal rates of accumulation or decumulation of memory.

In real life, we are not dealing with aberrations but with fields of choice which are not always convex and with marginal rates of substitution which are not always decreasing. The situations of concavity and of increasing psychological returns are sufficiently numerous for the theory to try and incorporate them within the framework of a limited rationality. The understanding of events which are simply presented as “irrational” can only stand to gain from this.

Essays in positive investment management, Third Edition - BLANQUÉ Pascal

In this important and timely book, Blanqué made a powerful claim for positive investment in order to avoid fanciful illusions. He assigned it the task of understanding what is happening in today’s world. Blanqué argued that the investment world contains many elements of a fairy tale and showed that a mere confrontation with reality leaves its mark on the impressive procession of theoretical, sacred cows, of established beliefs and truths. As does the confrontation with crises. These essays accordingly included an objective assessment of the discipline’s sacred cows and explored a number of ways to renew the traditional approaches. The book contains, in particular, a discussion of the notion of liquidity as the missing element of the modern portfolio theory; together with the changes in macro-financial regime as a key determining factor for investment strategies.
