As such, it offers viewers an active entertainment experience and industry players new business opportunities to learn better about and serve their audience and prospective customers.

Despite efforts by some of the best minds in our profession, monetary theory at the start of the 21st Century remains flawed by the same fundamental shortcoming that Clower (1967) pointed out in the 1960s, namely the absence of any useful model of money in which widespread monetary exchange the use of a common money in almost all transactions can be shown to arise endogenously. The models of mo...

The monument to the work initiated by Boole, the algebraization of logic, is the three volumes Algebra der Logik by Schröder (1841–1902), which appeared in the years 1890–1910, filling over 2,000 pages. Although the spirit of the subject came from the work of Boole and De Morgan, Schröder's volumes are really a tribute to the work of C.S. Peirce, along with Schröder's contributions. In addition...

T000032 Any series of observations ordered along a single dimension, such as time, may be thought of as a time series. The emphasis in time series analysis is on studying the dependence among observations at different points in time. What distinguishes time series analysis from general multivariate analysis is precisely the temporal order imposed on the observations. Many economic variables, su...

What is missing from the well-referenced perspective of the potential downsides for the future of humanity is any balancing assessment of the progress being made on these three challenges (a...

The literature on sustainability and the human future emphasizes the belief that population and/or mass consumption caused resource degradation and collapse in earlier societies. Archaeological literature proposing overshoot and collapse appears in current debates over resource conservation versus continued economic growth. The prominence of this debate, with its national and international dime...

Number skills are popularly bound to arithmetic knowledge in its symbolic form, such as “five + nine = fourteen,” but mounting evidence suggests that these symbolic relations are actually grounded, i.e., computed (see Harnad, 1990) on noisy internal magnitude representations that bear our general understanding of numbers and further improve with math experience (Figure 1). Multiple lines of evi...
