An Experiment with Pugilism.

An Introduction to Natural Experiment Studies

در دو سخن سردبیری شماره‌های قبل به مطالعات مداخله‌ای (Interventional and/or experimental studies) [1] و مطالعات نیمه تجربی (studies Quasi-experiment) [2] پرداختیم. همان جا، به این نکته اشاره کردیم که برای اندازه‌گیری کارآیی یک دارو، واکسن، برنامه بهداشت عمومی و متغیرهای دیگری از این دست، مطالعات مداخله‌ای بهترین گزینه هستند. تقسیم تصادفی و کورسازی از مؤلفه‌های اساسی یک مطالعه مداخله‌ای است [1]....

An Experiment with Inline Substitution

This paper describes an experiment undertaken to evaluate the effectiveness of inline substitution as a method of improving the running time of compiled code. Our particular interests are in the interaction between inline substitution and aggressive code optimization. To understand this relationship, we used commercially available FORTRAN optimizing compilers as the basis for our study. This pa...

Bubbling with Excitement: An Experiment*

Anecdotal and indirect empirical evidence suggest that excitement and market bubbles are intertwined, such that excitement not only arises during bubbles but may also help fuel them. We directly test the impact of excitement on bubbles in a bubbleprone experimental asset-pricing market (Capinalp, Porter, and Smith, 2001). Prior to trading, participants are assigned to emotion inductions through...

An Early Experiment with “Permazero”

We investigate a monetary regime with persistent, near-zero policy interest rates (“permazero”). This regime was implemented in 1683 by a prominent early central bank, the Bank of Amsterdam (“Bank”). Under this regime, the Bank’s policy rate remained at one-half percent for over a century. We employ archival data to reconstruct the Bank’s activities over a subsample of this regime (1736-1791) f...
