Tomáš Sabol Ekonómia pohlady z
interdisciplinárnych brehov
  • Tomas.Sabol_at_tuke.sk

Obsah
  • Non traditional economics
  • Specifics of information knowledge
  • Complexity and Complex adaptive systems
  • Intelligence, Reflexivity, Bounded rationality
  • Everything 2.0
  • Inspiration coming from biology evolution
  • Related concepts (chaos, graphs, Gödel, ...)
  • Najlahšie je rozprávat o tom, o com vieme málo,
    resp. skoro nic.
  • Pocul som to od pár múdrych ludí

Naozaj?
  • Bertrand Russell dropped his interest in
    economics after half a year's study because he
    thought it was too simple. Max Planck dropped his
    involvement with economics because he thought it
    was too difficult.
  • In 1990 Colander and Klamer asked students how
    important having a "thorough knowledge of the
    economy" was to succeeding as a economist. 3
    percent thought it very important, and 68
    thought it unimportant. Important was "Being
    smart in the sense of being good at problem
    solving" and "excellence in mathematics."
  • W. Brian Arthur Cognition The Black Box of
    Economics

4
  • I have always believed that the complexity of the
    problems facing mankind is growing faster than
    our ability to solve them.
  • Doug Engelbart

Ako sa stat inovatívnym?
  • What is it that enables Google to be so
    innovative?
  • We tell our engineering population, which is
    roughly 50 of all Googlers, to work 70 of their
    time on their core job, 20 of their time on
    projects that are loosely connected with their
    core job (so if they work on search, then maybe
    20 of their time looking at the fringes of
    search), and 10 of their time thinking about
    whatever they want to think about. No meetings.
    No emails. Nothing. You spend a day a fortnight
    thinking big thoughts.
  • Vice-president of Google .

Behavioral economic behavioral finance
  • A separate branch of economic and financial
    analysis, which applies scientific research on
    human and social, cognitive and emotional factors
    to better understand economic decisions by
    consumers, borrowers, investors, and how they
    affect market prices, returns and the allocation
    of resources
  • Theoretical basis for technical analysis
  • Concerned with the bounds of rationality

6
7
Information Economics (or Economics of
Information)
  • Studies how information affects an economy and
    economic decisions
  • Information (cf. knowledge) has special
    characteristics
  • Easy to create, but hard to trust
  • Easy to spread, but hard to control
  • Influences many decisions
  • Non-exclusion - consuming information does not
    exclude someone else from also consuming it (but
    artificial exclusion constructs)
  • Almost zero marginal cost - once the first copy
    exists, it costs (almost) nothing to make a
    second copy

7
8
Information Economics (or Economics of
Information)
  • Information market does not exhibit high degrees
    of transparency. That is, to evaluate the
    information the information must be known, so you
    have to invest in learning it to evaluate it
  • Information asymmetry - study of decisions in
    transactions where one party has more or better
    information than the other, creates an imbalance
    in power in transactions
  • The value of knowledge by its use (and
    enhancement by the users feedback) increases
    (the value of traditional assets by their use
    decreases)
  • This (compared with other types of goods)
    complicate bying/selling models many standard
    economic theories, new valuation techniques
    needed etc.

Knowledge Economy vs Traditional economy
  • The economics are not of scarcity, but rather of
    abundance. Unlike most resources that become
    depleted when used, information and knowledge can
    be shared, and actually grow through application.
  • The effect of location is either
  • Diminished in some economic activities using
    appropriate technology methods, virtual
    marketplaces virtual organizations offer
    benefits of speed, agility, 24/7, global reach
  • or, on the contrary, reinforced in some other
    economic fields, by the creation of business
    clusters around centres of knowledge
    universities, research centres.
  • Laws, barriers, taxes etc are difficult to apply
    solely on a national basis. Knowledge
    information "leak" to where demand is highest and
    the barriers lowest.
  • Knowledge enhanced products or services can
    command price premiums over comparable products
    with low embedded knowledge or knowledge
    intensity.

9
10
Knowledge Economy vs Traditional economy
  • Pricing and value depends heavily on context. The
    same information or knowledge can have vastly
    different value to different people, or even to
    the same person at different times.
  • Knowledge when locked into systems or processes
    has higher inherent value than when it can "walk
    out of the door" in people's heads.
  • See Tacit versus Codified knowledge
  • Human capital (competencies) - a key component of
    value, yet few companies report competency levels
    in annual reports ( cf. company valuation)
  • Communication - fundamental to knowledge flows.
    Social structures, cultural context and other
    factors influencing social relations are of
    fundamental importance

10
11
Economy of Knowledge
  • Growth of knowledge - complex evolutionary
    process
  • Adam Smith, Austrian school of economists
  • Production and management of knowledge in the
    frame of economic constraints
  • Knowledge-based economy the use of knowledge
    technologies (knowledge engineering, knowledge
    management) to produce economic benefits
  • Rules practices that determined success in
    industrial economy need rewriting in an
    interconnected, globalized economy where
    knowledge resources (know-how, expertise) are as
    critical as other economic resources
  • at the level of firms industries in terms of
    knowledge management
  • at the level of public policy as knowledge policy
  • Knowledge the most important asset

11
12
Network Economy
  • Products and services are created and value is
    added through social networks operating on large
    or global scales
  • New bussines models needed
  • Economies of scale stem from the size of the
    network - not the enterprise
  • open system is preferable to a closed system
  • see also Systems theory

12
13
Econophysics
  • Interdisciplinary research field, applying
    theories and methods originally developed by
    physicists in order to solve problems in
    economics - including uncertainty, stochastic
    processes, nonlinear dynamics
  • statistical finance - application to the
    financial markets
  • Many of the more interesting phenomena in
    financial markets fundamentally depend on
    heterogeneous agents and far-from-equilibrium
    situations (cf. Ilya Prigogine)
  • Physics models applied in economics percolation
    models, chaotic models (developed to study
    cardiac arrest), models with self-organizing
    criticality, models developed for earthquake
    prediction, mathematical theory of complexity and
    information theory (Claude Shannon, Murray
    Gell-Mann, )

13
14
Econophysics
  • Quantum economy - a quantum economic model of a
    finite economic system that consists of an
    economic subsystem with a certain number of
    buyers and sellers (economy agents) and its
    external environment (institutions) with certain
    interactions between economy agents, and between
    the economy agents and institutions
  • Analogies between finance theory diffusion
    theory (the Black-Scholes equation for option
    pricing is a diffusion-advection equation)

14
15
Complexity
  • Something with many parts in intricate
    arrangement
  • Often tied to the concept of a system a set
    of parts or elements, which have relationships
    among them differentiated from relationships
    with other elements outside the relational regime
  • Many definitions tend to assume that complexity
    expresses a condition of numerous elements in a
    system and numerous forms of relationships among
    the elements
  • Intricate inter-relationships that arise from the
    interaction of agents, which are able to adapt in
    and evolve with a changing environment
  • Complexity of a particular system is the degree
    of difficulty in predicting the properties of the
    system if the properties of the systems parts
    are given

Complexity

17
Complexity
  • Complexity includes ideas such as complex
    adaptive systems, self-organisation,
    co-evolution, agent based computer models, chaos,
    bifurcations, networks, emergence, fractals
  • Complex systems constructed so that they are on
    the boundary between order and chaos are those
    best able to adapt by mutation and selection.
    Chaos is a subset of complexity an example so
    called butterfly effect the idea is that a
    butterfly in Rio can change the weather in
    Chicago. An infinitesimal change in initial
    conditions leads to divergent pathways in the
    evolution of the system. Complex systems have
    evolved which may have learned to balance
    divergence and convergence, so that they're
    poised between chaos and order

17
18
Complex Systems
  • A scientific field which studies the common
    properties of systems that are considered
    fundamentally complex
  • A new approach to science that studies how
    relationships between parts give rise to the
    collective behaviors of a system and how the
    system interacts and forms relationships with its
    environment
  • A broad term encompassing a research approach to
    problems in economics, anthropology, artificial
    life, chemistry, computer science, evolutionary
    computation, earthquake prediction, meteorology,
    molecular biology, neuroscience, physics,
    psychology, sociology

18
19
Complex systems
  • One of Hayek's main contributions to early
    complexity theory is his distinction between the
    human capacity to predict the behaviour of simple
    systems and its capacity to predict the behaviour
    of complex systems through modeling. He believed
    that economics and the sciences of complex
    phenomena in general, which in his view included
    biology, psychology, and so on, could not be
    modeled after the sciences that deal with
    essentially simple phenomena like physics.

22
Complex Adaptive Systems (CAS)
  • A CAS is a complex, self-similar collection of
    interacting adaptive agents. The study of CAS
    focuses on complex, emergent and macroscopic
    properties of the system
  • Examples of complex adaptive systems include the
    stock market, social insect and ant colonies, the
    biosphere and the ecosystem, the brain and the
    immune system, the cell and the developing
    embryo, manufacturing businesses and any human
    social group-based endeavour in a cultural and
    social system such as political parties or
    communities. There are close relationships
    between the field of CAS and artificial life. In
    both areas the principles emergence and
    self-organization are very important.

22
23
Complex Adaptive Systems
  • A Complex Adaptive System (CAS) is a dynamic
    network of many agents (which may represent
    cells, species, individuals, firms, nations)
    acting in parallel, constantly acting and
    reacting to what the other agents are doing. The
    control of a CAS tends to be highly dispersed and
    decentralized. If there is to be any coherent
    behavior in the system, it has to arise from
    competition and cooperation among the agents
    themselves. The overall behavior of the system is
    the result of a huge number of decisions made
    every moment by many individual agents.

23
24
Complexity in Economics
  • Economic system is dynamically complex if its
    deterministic endogenous processes do not lead it
    asymptotically to a fixed point, a limit cycle,
    or an explosion
  • Some might argue that endogenous limit cycles
    also constitute complexity, but we shall view
    them as merely nearly complex
  • All systems that fit this definition have some
    degree of nonlinearity within them, however
    limited or arbitrary
  • Note There are nonlinear systems that are not
    complex, such as a standard exponential growth
    model

Complexity Economics
  • Application of complexity science to the problems
    of economics
  • One of the four C's of a new paradigm surfacing
    in the field of economics Cybernetics,
    Catastrophe, Chaos, Complexity
  • Rejects traditional assumptions that imply that
    the economy is a closed system that eventually
    reaches an equilibrium.
  • Views economies as open complex adaptive systems
    with endogenous evolution
  • Complexity economics rejects many aspects of
    traditional economic theory (mathematical models
    formulated in an analogy with early models of
    thermodynamics - based on the first law of
    thermodynamics, equilibrium)

26
27
Complexity Economics
  • Claims that traditional economic models never
    adapted to the latter discovery, remain
    incomplete models of reality, and that mainstream
    economists are yet to introduce information
    entropy to their models
  • Information entropy ("information uncertainty) -
    important concepts of organization and disorder,
    viewed as basic state parameters, in
    describing/simulating the evolution of complex
    (including economic) systems
  • Economic systems - no more considered as
    "naturally" inclined to achieve equilibrium
    states. On the contrary, economic systems - like
    most complex and self-organized systems - are
    intrinsically evolutionary systems, which tend to
    develop, prevailingly toward levels of higher
    internal organization though the possibility of
    involution processes - or even of catastrophic
    events - remains immanent

27
28
Complexity Economics (1/2)
  • No Global Controller no global entity controls
    interactions. Controls are provided by mechanisms
    of competition coordination between agents.
    Economic actions are mediated by legal
    institutions, assigned roles, shifting
    associations. No universal competitor a single
    agent that can exploit all opportunities in the
    economy
  • Continual Adaptation Behaviors, actions,
    strategies, and products are revised continually
    as the individual agents accumulate experience
    the system constantly adapts.
  • Cross-cutting Hierarchical Organization economy
    has many levels of organization and interaction.
    Units at any given level behaviors, actions,
    strategies, products typically serve as "building
    blocks" for constructing units at the next higher
    level. The overall organization is more than
    hierarchical, with many sorts of tangling
    interactions (associations, channels of
    communication) across levels.

28
29
Complexity Economics (2/2)
  • Dispersed Interaction What happens in the
    economy is determined by the interaction of many
    dispersed, possibly heterogeneous, agents acting
    in parallel. The action of any given agent
    depends upon the anticipated actions of a limited
    number of other agents and on the aggregate state
    these agents co-create.
  • Perpetual Novelty Niches These are continually
    created by new markets, new technologies, new
    behaviors, new institutions. The very act of
    filling a niche may provide new niches. The
    result is ongoing, perpetual novelty.
  • Out-of-Equilibrium Dynamics Because new niches,
    new potentials, new possibilities, are
    continually created, the economy operates far
    from any optimum or global equilibrium.
    Improvements are always possible and indeed occur
    regularly.

Complexity Economics (1/3)
Complexity Economics Traditional Economics
Agents Modelled individually use inductive rules of thumb to make decisions have incomplete information are subject to errors and biases learn to adapt over time heterogeneous agents Modelled collectively use complex deductive calculations to make decisions have complete information make no errors and have no biases have no need for learning or adaptation (are already perfect), mostly homogeneous agents
Networks Explicitly model bi-lateral interactions between individual agents networks of relationships change over time Assume agents only interact indirectly through market mechanisms (e.g. auctions)
Emergence No distinction between micro/macro economics macro patterns are emergent result of micro level behaviours and interactions. Micro-and macroeconomics remain separate disciplines
30
31
Complexity Economics (2/3)
Complexity Economics Traditional Economics
Evolution The evolutionary process of differentiation, selection and amplification provides the system with novelty and is responsible for its growth in order and complexity No mechanism for endogenously creating novelty, or growth in order and complexity
Technology Technology fluid, endogenous to the system Technology as given or selected on economic basis
Preferences Formulation of preferences becomes central individuals not necessarily selfish Preferences given Individuals selfish

Complexity Economics (3/3)
Complexity Economics Traditional Economics
Origins from Physical Sciences Based on Biology (structure, pattern, self-organized, life cycle) Based on 19th century physics (equilibrium, stability, deterministic dynamics)
Elements Patterns and Possibilities Price and Quantity
  • Complex systems emerge and maintain on the edge
    of chaos - the narrow domain between frozen
    constancy and chaotic turbulence

32
33
Evolutionary theory Economics
  • Connections Evolutionary theory ? Economics
  • One of the fundamental problems in economics -
    Bounded rationality
  • How can agents who are not infinitely rational
    and do not have infinite computational resources
    get along in their worlds?
  • There is an optimizing principle about precisely
    how intelligent such agents ought to be. If they
    are either too intelligent or too stupid - the
    system does not evolve well.

33
34
Evolutionary Economy
  • Heterodox school of economic thought that is
    inspired by evolutionary biology
  • Much like mainstream economics, it stresses
    complex interdependencies, competition, growth,
    structural change, and resource constraints but
    differs in the approaches which are used to
    analyze these phenomena
  • Paul Krugman What Economists Can Learn From
    Evolutionary Theorists
  • Economics is the study of phenomena that can be
    understood as emerging from the interactions
    among intelligent, self-interested individuals

34
35
Evolutionary Economy
  • Paul Krugman
  • Economics is about what individuals do
  • The individuals are self-interested
  • The individuals are intelligent
  • We are concerned with the interaction of such
    individuals
  • Whats different in comparison to the biological
    evolution? (BTW there is some difference)
  • Evolutionary theory about the interaction of
    self-interested individuals

35
36
Agent-based Computational Economics
  • ACE simulates and models economies as evolving
    systems of autonomous interacting agents
  • Growing Economies from the bottom-up
  • Multi-agent system - a system composed of
    multiple interacting intelligent agents, can be
    used to solve problems, which are difficult or
    impossible for an individual agent or monolithic
    system to solve.
  • Examples online trading, disaster response,
    modelling social structures

36
37
Agent-based Computational Economics
  • Altreva Adaptive Modeler - Building agent-based
    market simulation models for price forecasting of
    real-world stocks and other securities. A
    software application for creating financial
    market simulation models for the purpose of
    forecasting prices of real world market traded
    stocks or other securities or assets.

37
38
Economics with heterogenous interacting agents
  • Collaborate, compete and share
  • Collective behaviour of a population of
    interacting individuals often exhibits surprising
    properties, which can hardly be anticipated on
    the basis of the micro-economic interaction
  • Predictions of the game theory, however, are
    often contradicted by empirical and experimental
    research already in simple cases (the prisoners
    dilemma, the ultimatum game)
  • Doubts of the game theory validity in cases where
    individuals face a more complex strategic
    problem, involving a large number of other
    agents, uncertainty and limited information

38
39
Non-equilibrium Economy
  • Deals with processes that exhibit
    self-reinforcing causation, as opposed to
    standard neoclassical equilibrium economics
  • Represented by modern researchers in the fields
    of evolutionary-institutional economics, Post
    Keynesian economics, Ecological Economics,
    development and growth economics
  • "The Foundations of Non-Equilibrium Economics
    The Principle of Circular Cumulative Causation"
    (2009), Routledge

39
40
Attention Economy
  • Approach to the management of information that
    treats human attention as a scarce commodity, and
    applies economic theory to solve various
    information management problems
  • Attention is focused mental engagement on a
    particular item of information. Items come into
    our awareness, we attend to a particular item,
    and then we decide whether to act (Davenport
    Beck 2001)
  • A wealth of information creates a poverty of
    attention and a need to allocate that attention
    efficiently among the overabundance of
    information sources that might consume it (Simon
    1971)
  • Social attention
  • Dedicating too much attention to social
    interactions ? "social interaction overload"

40
41
Attention Economy
  • Coined by T. Davenport
  • Understanding and managing attention is now the
    single most important determinant of business
    success."
  • Thomas H. Davenport and John C. Beck, The
    Attention Economy Understanding the New Currency
    of Business (Boston Harvard Business School
    Press, 2001).

43
Collective Intelligence
  • A shared or group intelligence that emerges from
    the collaboration competition of many
    individuals
  • The capacity of human communities to evolve
    towards higher order complexity and harmony,
    through such innovation mechanisms as
    differentiation integration, competition,
    collaboration
  • Appears in a wide variety of forms of consensus
    decision making in bacteria, animals, humans,
    computer networks
  • Networking enabled by Web 2.0 (Enterprise 2.0),
  • cf. group think and individual cognitive bias
  • Collective Intelligence networks Prediction
    Markets
  • enormously efficient means to harbor and codify
    vast landscapes of information and bring them to
    bear on the most difficult problems -
    productivity, innovation and business performance

43
44
Swarm Intelligence (SI)
  • SI describes collective behavior of
    decentralized, self-organized systems, natural or
    artificial. SI systems - typically made up of a
    population of simple agents or boids interacting
    locally with one another and with their
    environment. The agents follow very simple rules,
    and although there is no centralized control
    structure dictating how individual agents should
    behave, local, and to a certain degree random,
    interactions between such agents lead to the
    emergence of "intelligent" global behavior,
    unknown to the individual agents. Examples of SI
    ant colonies, bird flocking, animal herding,
    bacterial growth,

44
45
Wikinomics
  • How Mass Collaboration Changes Everything, Don
    Tapscott and Anthony D. Williams
  • Four ideas Openness, Peering, Sharing, Acting
    Globally
  • Instead of an organized business body brought
    into being specifically for a unique function,
    mass collaboration relies on free individual
    agents to come together and cooperate to improve
    a given operation or solve a problem
    (Crowdsourcing)
  • Coase's Law A firm will tend to expand until the
    cost of organizing an extra transaction within
    the firm become equal to the costs of carrying
    out the same transaction on the open market
  • Inversion of Coase's Law A firm will tend to
    expand until the cost of carrying out an extra
    transaction on the open market become equal to
    the costs of organizing the same transaction
    within the firm

45
46
Other economics
  • Neuroeconomics
  • combines neuroscience, economics psychology to
    study how people make decisions
  • looks at the role of the brain when we evaluate
    decisions, categorize risks and rewards, and
    interact with each other
  • Service Economics
  • Service Oriented Economy

Reflexivita (George Soros)
  • Pomocou tohto princípu sa dívam na trhy. ... To,
    že trhy sú flexibilné platí, ale len do istej
    miery. Neviditelná ruka trhu nie je neomylná, nie
    vždy. ... Za normálnych okolností hladia trhy na
    realitu s miernym podozrením. Ale obcas sa stane,
    že nálady trhov sa šíria po špirále, bez
    sebakontroly, mohutnejú až do seba-deštrukcnej
    sily vtedy nastávajú bubliny.
  • Po prvé, financné trhy nereflektujú presne
    existujúcu situáciu, poskytujú obraz, ktorý je
    istým spôsobom zaujatý (biased) alebo
    skreslený. Po druhé, skreslené názory úcastníkov
    trhu, ktoré sa prejavujú v trhových cenách, môžu
    za istých podmienok ovplyvnit fundamenty, ktoré
    by mali trhové ceny reflektovat ...

47
48
Reflexivita (George Soros)
  • Trhy obycajne samy korigujú svoje chyby, ale
    obcas do nich preklzne nesprávne
    pochopenie/interpretácia, ktorá je schopná
    upevnit trend, ktorý už existuje v skutocnosti, a
    tým upevnit samu seba. Takéto sebaupevnujúce
    procesy môžu odtlacit trhy daleko od stavu
    rovnováhy. ... (tento proces) môže pokracovat
    dovtedy, kým nesprávna interpretácia zacne byt
    tak ocividná, že jej nesprávnost všetci pochopia
    ...
  • Túto obojstrannú spätnú, cyklickú spätnú väzbu
    medzi trhom, cenami a podcenenou realitou volám
    reflexivita.
  • Reflexivity circular, bidirectional
    relationships between cause and effect, both the
    cause and the effect affect one another in a
    situation that renders both functions causes and
    effects
  • Observations or actions of observers in the
    social system affect the very situations they are
    observing

48
49
Bounded Rationality (Herbert Simon)
  • Rationality of individuals is limited by the
    information they have, the cognitive limitations
    of their minds, and the finite amount of time
    they have to make decisions
  • Since decision-makers lack the ability and
    resources to arrive at the optimal solution, they
    apply their rationality only after having
    greatly simplified the choices available
  • Economic agents employ the use of heuristics to
    make decisions rather than a strict rigid rule of
    optimization
  • They do this because of the complexity of the
    situation, and their inability to process and
    compute the expected utility of every alternative
    action
  • In contrast with the concept of rationality as
    optimization

49
50
Bounded rationality (Herbert Simon)
  • Decision-maker is a satisficer (one seeking a
    satisfactory solution) rather than optimizer
  • Perfectly rational decisions are often not
    feasible in practice due to the finite
    computational resources available for making them
  • Most people are only partly rational, and are
    emotional/irrational in the remaining part of
    their actions
  • Economics is also about scarcity of our
    computational resources!

  • An autopoietic machine is a machine organized
    (defined as a unity) as a network of processes of
    production (transformation and destruction) of
    components which
  • i) through their interactions and transformations
    continuously regenerate and realize the network
    of processes (relations) that produced them and
  • ii) constitute it (the machine) as a concrete
    unity in space in which they (the components)
    exist by specifying the topological domain of its
    realization as such a network

  • With our knowledge of the universe, we have sent
    men to the moon.
  • We know microscopic details of objects around us
    and within us.
  • And yet we know relatively little about how our
    society works and how it reacts to changes
    brought upon it.
  • Humankind is now facing serious crises for which
    we must develop new ways to tackle the global
    challenges of humanity in the 21st century.
  • It is thus timely to create an ICT Flagship to
    explore social life on Earth, and everything it
    relates to, in the same way that we have spent
    the last century or more understanding our
    physical world.

FuturICT Project Goals
  • Develop novel ICT systems combining the best of
    human and computational abilities to support the
    understanding, integrative design, and management
    of complex systems,
  • Apply these to model techno-social and economic,
    transport, environmental and other global
    systems,
  • Create instruments to support the
    self-organization, decision-making and governance
    in politics, business, industry, and academia,
    with the aim to foster societal goals (e.g.
    robust techno-social and sustainable economic
    systems),
  • Develop principles and tools facilitating
    emergence of high quality processes, products and
    institutions in techno-social networks.
  • Multi-agent simulations of large systems (e.g.
    whole earth simulation, which may involve up to
    10 billion agents)
  • Multi-agent simulations considering human
    cognitive psychological processes (e.g.
    personality, memory, strategic decision-making,
    emotions, creativity etc.)

  • Realistic Theory of Economic Systems
  • Develop a realistic economic theory to give more
    reliable advise to decision-makers
  • Go beyond the paradigms of the Homo Economicus
    (the perfect egoist), efficient markets,
    equilibrium models, and representative agent
    models (mean-field models)
  • Develop agent-based models of boundedly rational
    behavior (e.g. limited cognitive capacities,
    behavioral biases and emotional aspects)
  • Consider randomness, extreme events,
    heterogeneity, non-linearity, emergence, and
    complexity to yield a greater descriptive and
    predictive model validity
  • Make models consistent with empirical and
    experimental data
  • Work out the mathematical connection between
    microscopic and macroscopic economic theories

Intellectuals are not original thinkers, but
purveyors of second-hand ideas (F. Hayek)
  • Ako vôbec môže niekto taký ako my - výsledok
    slepých zápasov evolúcie - dosiahnut akúkolvek
    formu neomylnosti?
  • Preto musím vo vede stále pripustit, že sa môžem
    vo všetkom mýlit.
  • To však znamená aj to, že sa môžem mýlit v tom,
    že sa vo všetkom mýlim.
