Overview

Overview

  • 1 Basic Theory:

    From economic processes to technological progress, and back

  • 2 More Theory:

    The role of technology in dynamic economic models

  • 3 From Theory to Policy:

    A consistent framework for analysis applied in Austria

  • 4 More Empirical Findings:

    Selected recent results of economic ICT impacts in Europe

Economics:

Primary metabolism of society

What is Information?

  • Periodicity: years, days

  • Living systems: adaption to periodicity, copy in structure, memory is impicit in evolved structure

  • Animals & Humans: memory explicit in individuals, used as model for anticipating behaviour

Basic Theory – I & C Processes 2

Commodity production:

Stable reproduction  stable money flows

coercive

Regulation of behaviour by power

institutions

ideological

 Market mechanisms, money, price systems (information technology)

Capitalism

Production of new information becomes necessary for the survival of production units

 new production processes, new products, new utilities, new institutions


Basic theory economics ict 1

Basic Theory – Economics  ICT 1

Maintenance of profitrate  new technology

Level of profits:  = revenue - cost

revenue = price x quantity

cost = wagerate x labourtime + interestrate x capital

Volatility of profits:  (profitrate) = f (stable relations)

within firms

Stable relations

between firms

between states


Basic theory economics ict 2

Basic Theory – Economics  ICT 2

New technology must drive:

price  : market power, quality (actual or perceived), price ratchets

quantity  : new products (versions), new needs (discovered or produced),

quantity ratchets, expanding geographical markets

wagerate  : against unions, lower reproduction cost, globalisation

labourtime  : technology, cheaper regulation (lower taxes)

interestrate  : finance versus industrial capital

capital  : technology, cheaper regulation (lower taxes)

infrastructure cost  : public institutions (education, health, transport, ...)

cost of social peace  : law, social identity, power systems, ...


Basic theory ict economics 1

Basic Theory – ICT  Economics 1

Information technology provides information commodities

  • Large amounts, very low variable cost

  • Bottleneck: opportunity cost of consumers (getting attention)

  • Bottleneck: selection of relevant information (names, „brands“)

  • Bottleneck: Decreasing information processing capacities

 Changing firm structure, changing institutional structure

 Global shake-up of profitrates


Basic theory ict economics 2

Basic Theory – ICT  Economics 2

Communication processes (subset of information processes)

Defining characteristic: temporal aspect

Information usually is accumulated in knowledge:

knowledge(T) = knowledge(T-1) + information(t) – obsolete information(t)

But:

Utility Ui(communication) of entity i builds up in time, is satisfied by communication and vanishes again. E.g. phone calls, music ...

Echo effects: not receiving communication signals is interpreted as signal!

 filling in attention gaps, economy of time, substitution strategies

More Theory

Selected model types describing technolgy in an economic context:

  • Money as information technology

  • Technology in search models

  • Production of public good information

  • Production of finite knowledge set information

  • Production of models


More theory money as information technology 1

More Theory – Money as information technology 1

General Equilibrium Theory:

typical

Observed quantities and coins carry information:

Strong welfare implications !

More Theory – Money as information technology 2

Disequilibrium theories:

  • Prices signal needs of households

  • Markets transmit need signals to production units

  • Production units signal their technological possibilities to markets

  • Markets transmit technology signals to households

  • Exchange takes place in market disequilibrium

  • Adaption takes place in expectations disequilibrium

  • Evolution of needs due to disequilibrium

  • Evolution of technology due to disequilibrium


More theory technology in search models

More Theory – Technology in search models

Example: Searching for a low price shop

No information acquired

Information bought

Use information if

that is

Firm 2

no R&D

-10, 10

More Theory – Production of public good information

The R&D game:

Not enough R&D in basic research!

 Public funding

 Patent system

Cheaper and more advanced ICT cannot help.


More theory production of finite knowledge set information

More Theory – Production of finite knowledge set information

Tragedy of the Commons model

Several firms produce information in the same finite knowledge area.

Since for every single firm additional R&D still is profitable, they

still carry on, even if (from an aggregate point of view) it would be wise

to move to a new area of research.

 Clear property rights

To much R&D is carried out!

 Promote cooperation

Advanced ICT might even worsen the problem!


More theory production of models

World (Model MW)

z0 = w0 + 0 u1 + ß0 u2

Entity 1 (Model M1)

z1 = 1 u1 + ß1 u2

Entity 2

Original Model M2:

z2 = ß2 u2

Modified Model MM2:

z2=(1-)ß2 u2+(1Mu1+ß1M u2)

Ideological Model MM:

z1M = 1M u1 + ß1M u2

More Theory – Production of Models

Ideological Power

The cheaper ideological influence (advanced ICT) the less direct coercive

power is needed!
