Economic Impacts of Information and Communication Technologies Univ.-Prof.Dr. Hardy Hanappi Institute of Economics University of Technology of Vienna http://www.vwl.tuwien.ac.at/hanappi/
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
Basic Theory • Economic Processes • Information & Communication Processes • Economics ICT • ICT Economics • History: Economics ICT
society Basic Theory – Economic Processes 1 Economics: Primary metabolism of society primary distribution process production time time secondary distribution process Classical view of reproduction and growth consumption
Basic Theory – Economic Processes 2 Commodity producing societies Distribution 1 production Distribution 2 consumption organisation commodities reproduction growth revenues production units markets expenses commodities households labour expenses wages households
Basic Theory – I & C Processes 1 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 memory models individual society language
Basic Theory – I & C Processes 2 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 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 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 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 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
Basic Theory – Economics ICT 1 Prevailing direction of causality: From economics to ICT
Basic Theory – Economics ICT 2 Swarming:
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 General Equilibrium Theory: typical 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 Example: Searching for a low price shop No information acquired Information bought Use information if that is
Firm 2 no R&D R&D Firm 1 no R&D 0, 0 10, -10 R&D -10, 10 5, 5 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 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!
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!
From Theory to Policy • A model for Austria • How information technology enters • Some quantitative results
From Theory to Policy – A model for Austria sectors cons. inv. gov.exp. Input Output Analysis sectors aij Final demand components wages GDP distribution profits
From Theory to Policy – How information technology enters 1. As a sector in IO-analysis 2. Modified by R&D policy Public R&D expenditure (socioeconomic structure) Innovation Model AUSTRIA 3 Macroeconomic Rsults General University Fund Human Capital Model Regulations
From Theory to Policy – Some selected results 1 Four policies: Demand side, supply side, deregulation, education initiative
More Empirical Findings • Recent Eurostat statistics • Results from the S.T.A.R. project • The productivity paradoxon

More empirical findings – S.T.A.R. 2 • Ambivalent influence of ICT on employment • Peacemeal engineering succeses in e-commerce • Slow recovery from the stock exchange bubble The productivity paradoxon starts to be solved !
