Experimental economics
Experimental economics is the use of experimental methods to evaluate theoretical predictions of economic behaviour. It uses controlled, scientifically-designed experiments to test economic theories under laboratory conditions. Typical empirical research is limited by the fact that only a subset of the set of all possible influences affect (or can be observed to be affecting) economic decision making; therefore, the ability to control for certain influences is limited or non-existent. With experiments, economists can fix some inputs and measure the effects of other inputs in a way that allows ceteris-paribus comparisons.

Oct. 25, 2025 — A new study shows that eating more fruits and vegetables during the day can significantly improve sleep that same night. Researchers found a clear link between diet quality and sleep depth, with participants who met the CDC’s daily produce ...
Oct. 25, 2025 — Researchers found that neurons can use fat, not just sugar, to power the brain. When a protein called DDHD2 fails, this process breaks down and leads to serious brain problems. Scientists were able to restore damaged cells by feeding them fatty ...
Oct. 25, 2025 — Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate ...
Oct. 24, 2025 — A massive genetic study found that naturally lower cholesterol is linked to a dramatically reduced risk of dementia. The research simulated the effects of cholesterol-lowering drugs and showed up to an 80% lower risk for certain genetic profiles. ...
Oct. 24, 2025 — Researchers have finally seen and measured the tiny alpha-synuclein oligomers that may ignite Parkinson’s disease. With the ultra-sensitive ASA-PD imaging method, they captured these clusters in brain tissue, finding larger and more numerous ...
Oct. 23, 2025 — Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier brain structures. The cells seemed to protect ...
Oct. 22, 2025 — Scientists have uncovered a toxic alliance between Aβ and fibrinogen that may explain how Alzheimer’s disease begins. The two proteins together create stubborn clots that damage blood vessels and spark inflammation in the brain. These effects ...
Oct. 21, 2025 — New research reveals that exercise counteracts the mood-damaging effects of a Western-style diet through specific gut and hormonal mechanisms. Running restored metabolites tied to mental well-being and balanced key hormones like insulin and leptin. ...
Oct. 21, 2025 — Mizzou scientists are exploring how a ketogenic diet may protect the brain and prevent Alzheimer’s in people genetically predisposed to it. Their study found that female mice with the APOE4 gene benefited most, showing improved gut and brain ...
Oct. 21, 2025 — Menopause brings profound shifts not just in hormones but in the very structure of the brain. Scientists have found that gray matter in regions tied to memory and thinking can shrink, while white matter may show damage linked to blood flow issues. ...
Oct. 21, 2025 — Scientists at UCSF have uncovered evidence that multiple sclerosis silently damages the brain years before diagnosis. By studying proteins in blood samples, they identified early immune signals and markers of nerve damage. The findings point to IL-3 ...
Oct. 20, 2025 — A massive brain imaging study of nearly 30,000 people has uncovered striking connections between eating ultra-processed foods and measurable changes in brain structure. These changes may be tied to overeating and addictive eating patterns, though ...
