This article summarizes a review of the literature presented in Sacerdote (2011) . I thank Ricardo Mora for bringing it to my attention. The simplest model of behavioral genetics assumes that child outcomes (Y) are produced by a linear and additive combination of genetic inputs (G), shared environment (F) and unexplained factors (S). For instance […]

Crocodiles, alligators use lures to attract prey Alligators and crocodiles use lures to entice prey, the first reported use of tools by reptiles. Researchers surveyed alligators and crocodiles at four sites in Louisiana for a year, noting that the creatures balancing twigs and sticks on their snouts to lure birds during nesting seasons. “Use of […]

The first known application of modern economic techniques to solving epistemic problems in science was very explicit in describing the value of a scientific theory as the difference between ‘costs’ and ‘benefits’. I’m referring to Charles Sanders Peirce’s ‘Note of the Theory of the Economy of Research’, published in 1879, less than a decade after […]

Hummingbird species evolved to live in oxygen-thin Andes Some species of hummingbirds, which need lots of oxygen to survive, have evolved to thrive in the oxygen-poor heights of the Andes. Researchers sequenced 63 hummingbird species’ DNA and found that the mutations that allow the Andes birds to breathe at high altitudes occurred at the same […]

Competitive markets are efficient under a number of conditions. One is that the consumption or production of the commodity to be traded must not cause externalities. For instance, consider a group of firms polluting the atmosphere or the waters of a nearby river. The individual behavior is typically not sufficient to keep the pollution level […]

Originally, intellectual property legislation was created on the assumption that the profits derived from the monopoly of the patented inventions would encourage innovation and thus promote economic growth. This is one of many hypotheses that the vast majority of economists have ever considered as intuitive. Accordingly, it is generally believed that the patent system is […]

Specially shaped snouts help seahorses sneak up on their prey Seahorses have a nose for prey; their unique snouts are shaped to create very little disturbance in the water, allowing them to stealthily pounce on their intended meal, according to a study published in Nature Communications. “The seahorse is one [of] the slowest swimming fish […]

Strawberry poison frogs pass on chemical defense to offspring Strawberry poison frogs provide chemical defenses to their tadpoles by feeding them eggs spiked with alkaloids. Researchers measured alkaloid content in the frogs during different stages of development, separating them into two groups — one in which tadpoles were reared and fed by their mothers and […]

Researchers try to figure out sea worm’s blue glow Researchers are a step closer to figuring out why a common sea worm glows blue on the shallow seafloors it calls home, thanks to a pair of experiments conducted by biologists at Scripps Institution of Oceanography. First, they found that the worm, unlike other light-emitting organisms […]

The term ‘economics of scientific knowledge’ (ESK) was coined as a reaction to the field known from the seventies as ‘sociology of scientific knowledge’. The latter had been defined by the members of the so called ‘Strong Programme’ in contraposition to the classical notion of a ‘sociology of science’, having in mind a distinction between […]
