Decision Making as Output and Bounded Rationality

  The classical economics theories proceed on the assumption of rational agents. Rationality implies the economic agents undertake actions or exercise choices based on the cost-benefit analysis they undertake. The assumption further posits that there exists no information asymmetry and thus the agent is aware of all the costs and benefits associated with the choice he or she has exercised. The behavioral school contested the decision stating the decisions in practice are often irrational. Implied there is a continuous departure from rationality. Rationality in the views of the behavioral school is more an exception to the norm rather a rule. The past posts have discussed the limitations of this view by the behavioral school. Economics has often posited rationality in the context in which the choices are exercised rather than theoretical abstract view of rational action. Rational action in theory seems to be grounded in zero restraint situation yet in practice, there are numerous restra

Rational Spending Rule : To be rational or not



Rational spending rule, despite the abstract derivation, can be used to make sense of several real world phenomenon.
                                               
Some cities have grown vertically while the rest have grown horizontally. To use popular analogy, it can be described as the lift vs the car model. The answers can be sought in utility analysis. Cities which are short of space find it difficult to accommodate people close to the city center. The cost of land being high deter people and either move them to the margins or compel to look at alternatives. Similar is the case with commercial space in land starved locations. An analysis would probably reveal a greater spending on alternative goods than housing.  It need not necessarily be for upper income groups alone.

Experts have often wondered on the increased consumption of consumer electronics or durable goods in poorer localities. Dharavi in Mumbai may not have enough space to provide basic housing and sanitation, but residents possess televisions, mobile handsets and two-wheelers. The high costs of land put them off from building a house or purchasing an apartment and instead focus on acquisition and usage of durable and fashion accessories. Further no legal or formal land titles, they may not choose to invest on sanitation, clean running water and better housing. Substitution effect, people tend to move to cheaper goods when a price of a good goes up, can be used to explain these. 

In certain cities, while the alternative to owning a house is renting a house, the desire to own a house at minimum expenditure makes individuals look for flats as an alternative. In some cities in California, the pull effect, despite market implosion for housing, has led to condos/townhomes almost selling twice the number of houses.


In London, there was a plan to reduce plastic bottles (plastic bottles increase litter causing environmental degradation). The alternatives suggested were to increase the number of fountains while allowing consumers to bring their own bottled water. An analysis of consumer preferences would make an interesting reading. Consumers may now drink from fountains (Excercising their less preferred choice than before while earning lower revenue (tax on bottled water) and increased costs (costs of setting and maintain the fountain); switching to juice and soft drinks ( no impact on reduction in plastic litter while in a drop in consumer utility); switch to no use of water ( lowers consumer utility on account of possible exhaustion/dehydration by lack of access to water). In other words, a policy design needs to examine the utility of the consumers.

Subsidies in US cities for sports stadiums have come in for criticism on the grounds of substitution effect. Subsidy proponents argue the employment opportunity and impact on real estate market as key reasons for continuing the subsidies. An analysis using substitution models reveal that the spending on sports is essentially a movement from expenditure on alternative goods. A family which now goes for watching sports in the stadium would sacrifice its earlier choices of entertainment at a theatre, movie house, pantomime etc. Therefore the income would remain same only a movement on the budget line to new consumer equilibrium.

Often we find heavy queues in front of the PDS stores. Most of them would be from lower income groups. Generally, similar long queues are not found in high end markets. This could be attributed to the willingness of higher income groups to pay more to avoid standing in queues than the poorer sections of the society. Yet one does see long queues in some leading retail outlets’ billing counters. Any suggestions to avoid queues??
