The COVID-19 pandemic poses a major challenge to policy makers on how to encourage compliance to social distancing and personal protection rules. This paper compares the effectiveness of two policies that aim to increase the frequency of responsible health behavior using smartphone-tracking applications. The first involves enhanced alert capabilities, which remove social externalities and protect the users from others’ reckless behavior. The second adds a rule enforcement mechanism that reduces the users’ benefit from reckless behavior. Both strategies should be effective (...) if agents are expected-value maximizers, risk averse, and behave in accordance with cumulative prospect theory or in accordance with the Cognitive Hierarchy model. A multi-player trust-game experiment was designed to compare the effectiveness of the two policies. The results reveal a substantial advantage to the enforcement application, even one with occasional misses. The enhanced-alert strategy was completely ineffective. The findings align with the small samples hypothesis, suggesting that decision makers tend to select the options that lead to the best payoff in a small sample of similar past experiences. In the current context, the tendency to rely on a small sample appears to be more consequential than other deviations from rational choice. (shrink)

Bogdanov is a major rival to the philosophical orthodoxy of Plekhanov and Lenin. We explicate the foundational notions of his philosophy—praxis and experience—and trace his revisionism to Kant, Fichte, Mach, and Spencer. We show that Bogdanov's approach represents a predominantly pragmatic reading of Marx, influenced by the empiricism of Mach and Spencer as well as by Kantian apriorism. Bogdanov's version of Unified Science—Tektology—is considered against his philosophical background. The concept of praxis is at the center of the controversy between Marxist (...) orthodoxy and revisionism. We analyze the connection between Bogdanov's philosophy of praxis, and the constructivism of the young Marx. Consequently, we see how Bogdanov's quest for infinite creativity is conceptually connected with the Fichtean–Marxian quest for infinite growth. Furthermore, we consider the issue of technological growth in a framework of the contemporary limits to growth debate. (shrink)
