How does consumer choose? The mainstream answer is at odds with everyone's experience. A better formalization is offered by agent-based models with large degrees of imperfect information and bounded rationality, buiding upon and going beyond behavioural economics.

Prices and quantities This paper explore mismatches between basic textbook theory of economics and empirical evidence from the real world that you can collect by yourself, so to replicate (confirming, widening or rejecting) the proposed analyses, as a scientific approach would authorise and ask for. If you are a student, this is an excellent paper to understand the importance of the information used by real consumers to make their choices. We contest the existance of a one-to-one relationship between price and quantity demanded, so putting in crisis a tenant of neoclassical economics, but leading way to a viable new generation of models and policy-relevant insights. Policy insights for sustainability and the energy transition Consumer
theory: the neoclassical model and its opposite evolutionary alternative
A free software allows you for direct experimentation and provides examples in plain numbers. A must for understanding behavioural economics approach to consumers.
The rich and the poor An exploration of differences in decision-making routines and outcomes between the rich and the poor, by leveraging a new key concept (cumulative bundle) and a software. We demonstrate the empirically testable statements that the share of well-off people in the sales on a market is systematically higher, the higher the price that prevails on that market.
Evolutionary Economics, Responsible Innovation and Demand: Making a Case for the Role of Consumers (2018)
Consumer decision rules for agent-based models A clear-cut introduction to evolutionary consumption microfoundation in agent-based models. It proposes several rules to cope with budget constraints, product differentiation, purchase repetition over time. In particular, you shall find the rules of consumer behavour used in the freely downloadable model "Race to market", which gave rise to these micro-data. Moreover, it suggests to ACE modellers a "golden rule" for more realistic models. Essay: Analysing retailing opportunities and threats using agent-based simulation As a valuable supporting tool for the marketing analysis of opportunities and threats on retail markets, an agent-based simulator - including rules proposed here - is explained, providing insights to answer to questions such as: - What happens in the distribution landscape
if we open a new outlet? Where should it be located? What profile
(assortment composition, price levels, size) the new outlet should
have?

Consumption expenditure by income classes A typical monthly expenditure structure for different consumption needs, differentiated by income classes of the households. The confirmation of Engel's law of decreasing importance of food (the higher the income) is accompanied by a host of other interesting features.

Essay: Package size, price, and consumer rules Optimal commercial offer by retailers depends not only on efficient logistics and buyer's power with respect to the supply chain: it hinges on the segmentation of customers according to their rules of choice. In this paper, an example of purchase basket over many categories, varieties and package sizes is constructed and commented, freely offering the Excel file with all open programming code. Consumers can find out their style of shopping; managers have a device to fix the prices in your commercial premise, the researchers and the absolute beginners can simply explore the unexpected consequences of the interaction of such trivial, but real, things like package size, weight, and budget constraints.

This
paper explains and offers you a powerful software tool for understanding
the introduction of product and process innovation
in a competitive market. Consumers are individual agents with different
tastes and personal income. In terms of industrial dynamics, you'll
see how product life cycles arise by personally playing the software
model or by observing how artificial agents perform. A consumer memory-based model of new product diffusion within a social network by J. Kottonau, J. Burse, C.
