This paper is a non-technical and somewhat philosophical essay, that seeks to investigate the relationship between economics and reality. More precisely, it asks how reality in the form empirical evidence does or does not influence economic thinking and theory. In particular, which role do...

In this essay I review Sylvia Nasar's long awaited new history of economics, Grand Pursuit. I describe how the book is really an economic history of the period from 1850-1950, with distinguished economists' stories inserted in appropriate places. Nasar's goal is to show how economists work, but...

We compile the list of articles published in major refereed economics journals during the last 35 years that have received more than 500 citations. We document major shifts in the mode of contribution and in the importance of different sub-fields: Theory loses out to empirical work, and micro...

More advanced technologies demand higher degrees of specialization - and longer chains of production connecting raw inputs to final outputs. Longer production chains are subject to a "weakest link" effect: they are more fragile and more prone to failure. Optimal chain length is determined by the...

Globalization has made it possible for labor in developing countries to augment labor in the developed world, without having to relocate, in ways not thought possible only a few decades ago. We argue that this large increase in the developed world's effective labor supply, triggered by...

The...

The relative performance of China and India is compared using two different methods and they provide a very different picture of their relative performance. We compare the average absolute values of indictors for the decade of the 1980s, 1990s and the 2000s. We use indicators such as the current...

Purchasing power parity exchange rates, or PPPs, are price indexes that summarize prices in each country relative to a numeraire country, typically the United States. These numbers are used to compare living standards across countries, by academics in studies of economic growth, particularly...
