Economics is not only a social science, it is a genuine science. Like the physical sciences, economics uses a methodology that produces refutable implications and tests these implications using solid statistical techniques. In particular, economics stresses three factors that distinguish it from...

This review considers the evolution of economic thinking on the relationship between digital technology and inequality across four decades, encompassing four related but intellectually distinct paradigms, which I refer to as the education race, the task polarization model, the...

We identify three separate stages in the post-World War II history of applied microeconomic research: A generally non-mathematical period; a period of consensus (from the 1960s through the early 1990s) characterized by the use of mathematical models, optimization and equilibrium to generate and...

This paper investigates whether the parameters of labor demand functions are sensitive to alternative methods of estimation. The assumption that the production technology is of the Generalized Leontief type implies that the demand system can be estimated by analyzing cross-section differences in...

The history of the twentieth century can be summarized excessively briefly in five propositions: First, that the history of the twentieth century was overwhelmingly economic history. Second, that the twentieth century saw the material wealth of humankind explode beyond all previous imagining....

The answer to the question in the title is: A lot. In this essay, I argue that the history of macroeconomics during the 20th century can be divided in three epochs: Pre 1940. A period of exploration, where macroeconomics was not macroeconomics yet, but monetary theory on one side, business cycle...

This paper estimates the nature and magnitude of the local externalities from own industry scale, as envisioned by Marshall. Census panel data on individual plants in high-tech and machinery industries across up to 487 countries are utilized, to quantify the direct effects of local external...

This paper revisits and proposes a resolution to an empirical and theoretical controversy between Keynes and the "classics" (or monetarists). The controversy dates to Keynes's General Theory (1936)--most famously formalized in Hicks's (1937) classic Econometrica article, in which the IS-LM model...

This paper investigates the drivers of support for market mechanisms (competition and optimizing behavior by agents). We elicit such attitudes using concrete and simplified situations where respondents face a tradeoff between an economically efficient situation and a pro-social objective. We...
