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

Algorithmic Black Boxes, Data Scientists and Trade-offs

There is a thought provoking article published in the Forbes on the directions in data science and their probable implications. Its title is quite catchy ‘How Data Scientists turned against Statistics”. At least on the title, it seems to capture a conflict that seems ongoing between the data scientists resting on their tools and the statistical methods and kit that one has got used to in the days of the small datasets. The article seems to posit a trade-off. The trade-off is the larger the datasets, the lower the statistical rigour by an individual analyst who will instead prefer to use automated tools. The sophisticated construction of statistical methodology and consequent inferences give way to automated construction of data collection methodological, analytical and inferential tools with little control in the hands of the data scientist. In the words of the author, the giant leap into the world of data has been accompanied by a giant leap of faith the outcome of which is there is
