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

Perverse Incentives!

There is a proverbial story about snakes in Delhi. During British days, apparently there was a time when Delhi was infested with snakes. The authorities were challenged to find a solution to the snake menace. People respond to incentives and one might not take recourse to economics for the same and instead follow common sense. So the authorities announced a reward for all those who kill snakes. The condition was the dead snake has to be produced as proof for claiming reward. The story goes when the reward was stopped, Delhi was infested with far more snakes than it began with. In other words the problem had multiplied. Without doubt, one needs to look why the policy failed. Does this story remind us that economics is not infallible and incentive mechanism does not work? Let us probe it in some depth. As Adam Smith first pointed out, at least in documented modern times, people function in their self interest. The self interest as an aggregate is what culminates into enlightened c

Reality shows, fashion parades, cricket coaching classes, entreprenurship- what binds them together?????

What makes people attract towards reality shows? Why do you see such a craze among parents to put their wards for cricket coaching classes? We see mushrooming of cricket coaching centres each advertising that the kid is a potential IPL player? Similarly what makes a industrialist like N,R.Narayana Murthy a role model for many a family? If this is not enough, take the craze for shopping festivals and modelling contests or fashion parades. Each of these activity may seem disconnected yet a common chord binds these all. People respond to incentives. A reality show winner is a kind of role model of many others aspiring that success and the rewards that come along with that success. the chances of success are not high yet the fact if we win, we hit a jackpot make the people crazy. One will not produce a Tendulkar, Richards or Dhoni or Steyn everyday. the success and the accompanying rewards that one gets makes kids and their parents want to try hand in cricket. Along the line at certai

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 sanita

Unlimited all the way- Diminishing Marginal Utility in Practice?

As one walks in to a five star hotel, we find ourselves inclined to try Buffet Meals for a fixed price. Andhra restaurants have become popular for offering unlimited meals. As we visit few amusement parks, we find they charge a fixed entrance fee and let us enjoy unlimited rides. Mobile service providers woo customers by offering unlimited SMS per day at a flat fee. Bangalore Metropolitan Transport Corporation (BMTC) lures us to try its buses with a day pass (unlimited rides for a flat fee for the calendar day). Further for ages we have had the concept of Bus passes for students and frequent users as also the Suburban rail passes in Mumbai and other cities in India.   Internet service providers offer unlimited browsing per month for a flat fee. Unlimited rides in public transports, enjoy unlimited SMS, telephone calls, internet usage or even unlimited cuisine sound attractive and are part and parcel of our daily economic life. Yet step back and wonder what logic prevails here. Th
