Five studies show that people, including experts such as professional chefs, estimate quantity decreases more accurately than quantity increases. We argue that this asymmetry occurs because physical quantities cannot be negative. Consequently, there is a natural lower bound (zero) when...

Motivated by recent empirical findings on the relationship between new clinical evidence and the effectiveness of detailing, this paper develops a new structural model of detailing and prescribing decisions under the environment where both manufacturers and physicians are uncertain about drug...

It only took an apple to fall on the head of Newton and what happened is history. Even though the book has nothing to do with physics we feel research effects business across the world as gravity affects life matter. Gravity is a key force behind the existence of life on earth, same way...

Social networking has now become an integral part of lives of modern citizens of India. There will hardly be any one who is not aware about at least one social networking site or app, whether he uses that or not. This covers school students also. It has been common now for households to have a...

Do information technology (IT) investments improve firm profitability? If so, is this effect because such investments help improve sales, or is it because they help reduce overall operating expenses? How does the effect of IT on profitability compare with that of advertising and research and...

This paper assesses empirically the relationship between marketing expenditures and sales in the premium car segment in Germany. We employ a new data-set which contains model-specific data on sales (i.e. registrations), restyling activities and marketing expenditures at a monthly basis for the...

A large literature has documented significant public health benefits associated with the minimum legal drinking age in the United States, particularly because of the resulting effects on motor vehicle accidents. These benefits form the primary basis for continued efforts to restrict youth access...

We consider the effect of legal access to alcohol, which is known to increase drinking behavior, on academic performance. We first estimate the effect using an RD design but argue that this approach is not well-suited to the research question in our setting. Our preferred approach instead...

Due to Federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use these discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...
