Higher Order Learning

AbstractWe design a novel experiment to study how subjects update their beliefs about the beliefs of others. Three players receive sequential signals about an unknown state of the world. Player 1 reports her beliefs about the state; Player 2 simultaneously reports her beliefs about the beliefs of Player 1; Player 3 simultaneously reports her beliefs about the beliefs of Player 2. We say that beliefs exhibit higher-order learning if the beliefs of Player k about the beliefs of Player $$k-1$$ k - 1 become more accurate as more signals are observed. We find that some of the predicted dynamics of higher-order beliefs are reflected in the data; in particular, higher-order beliefs are updated more slowly with private than public information. However, higher-order learning fails even after a large number of signals is observed. We argue that this result is driven by base-rate neglect, heterogeneity in updating processes, and subjects’ failure to correctly take learning rules of others into account.

Common Learning

We study repeated games in which players learn the unknown state of the world by observing a sequence of noisy private signals. We find that for generic signal distributions, the folk theorem obtains using ex post equilibria. In our equilibria, players commonly learn the state, that is, the state becomes asymptotic common knowledge.

Definition Of

The paper examines various approaches to the definition of the term «digital economy» in the scientific and business environment along with factors and forms of its development in different countries taking into account the specifics of the current stage of the Russian economy, which is a matter of particular importance in seeking new sources of the world economy growth. The subject of the research is opportunities and threats inherent in the process of digitalization of economies and their impact on the operation of international and national markets as well as the development of the world economy as a whole. The purpose of the paper was to analyze the practical experience in the formation and development of the digital economy in foreign countries and Russia and identify the changes it brings to the activities of state institutions and business structures, established rules of market exchange, the process of promotion and use of innovations. All the above made it possible to determine the country-level specifics of the digital economy evolution reveal the contradictory nature of its manifestations and justify the necessity for active participation of the state in stimulation and support of potentially promising digital innovations in various sectors of the economy. It is concluded that the level of the digital economy development depends on the real-sector performance, the maturity of markets, the state of the national economy. It is highlighted that the criteria for a comprehensive assessment of the results of the economy digitalization must be developed.

Key Aspects

The article deals with the fundamental, inherent in most of the countries of the world transformation of state power, its formation, functioning and division between the main branches as a result of the decentralization of such power, its subsidiarity. Attention is drawn to the specifics of state power, its func- tional features in the conditions of sovereignty of the states, their interconnec- tion. It is emphasized that the nature of the state power is connected with the nature of the political system of the state, with the form of government and many other aspects of a fundamental nature.It is analyzed that in the middle of national states the questions of legitima- cy, sovereignty of transparency of state power, its formation are acutely raised. Concerning the practical functioning of state power, a deeper study now needs a problem of separation of powers and the distribution of power. The use of this principle, which ensures the real subsidiarity of the authorities, the formation of more effective, responsible democratic relations between state power and civil society, is the first priority of the transformation of state power in the conditions of modern transformations of countries and societies. It is substantiated that the research of these problems will open up much wider opportunities for the provi- sion of state power not as a center authority, but also as a leading political structure but as a power of the people and the community. In the context of global democratization processes, such processes are crucial for a more humanistic and civilized arrangement of human life. It is noted that local self-government, as a specific form of public power, is also characterized by an expressive feature of a special subject of power (territorial community) as a set of large numbers of people; joint communal property; tax system, etc.
