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

Big Data and Diminishing Returns

-
In many industries has become the buzzword. Scarcely a discussion seems to happen without touching upon the perceived advantages of big data. Firms seem to outcompeting with each other in collecting reams of data. The question however is the effectiveness of this data. The firm’s outcomes are determined primarily by the utilization of big data rather than collection of data per se. Ferreting out big data is a challenging task. Although the big data presents a data set that shows 10X or 100X in relation to existing mechanisms, it does not necessarily convey 10X or 100X worth of increase in insight. While the implication of big data is that quantity is paramount, the returns generated do not match the quantity of data generated. Big data too is subject to diminishing returns. Experts point out, it is not per se the data that should be big, but the primary factor that counts is the diversity of data. Even if datasets may be small, the amount of richness they provide when the

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

Caselets in Macroeconomics

-
Caselet I- Rupee depreciation and textile industry The recent rupee depreciation has enabled the Indian textile industry to hold yarn prices and also increase yarn exports.   Though Indian industry demonstrates stronger backward linkages, low labour costs have enabled countries like Bangladesh, Pakistan and Vietnam to overtake India in terms of capturing textile export markets.   With Chinese Yuan appreciating, Indian exports have become more competitive. Indian textile export share is marginal ( 5% as compared to China’s 30%). Many analysts advocate leveraging the current scenario to capture the global market at the expense of China.   As a CEO of leading textile manufacturer, you are planning to go in for capacity expansion. Capacity expansion necessitates funding and thus you approach a consortium of banks. Prepare the detailed projections convincing the bankers how the global economic trends portray well for Indian textile exporters. (Note: Use financial statements sh

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
