Technological Progress: Invention, Innovation, and Diffusion - Theories, Models, and Economic Implications
- 1. Technological Progress: Invention, Innovation, and Diffusion - Theories, Models, and Economic Implications Dr. Arifa Saeed
- 2. Theories, Models, and Economic Implications Definition: Technological progress refers to the continuous improvement of tools, systems, and processes that enhance productivity, efficiency, and economic growth. Three Key Aspects: o Invention – The creation of new ideas or products. o Innovation – The process of refining and commercializing inventions. o Diffusion – The spread and adoption of new technologies across markets and societies. The transition from steam engines to electric motors revolutionized industries.
- 3. Joseph Schumpeter (1883–1950) emphasized the role of technological progress in economic growth. His most important contributions include: 1. Innovation as the Engine of Economic Growth o Unlike classical economists who focused on capital and labor, Schumpeter argued that new technologies drive economic progress. o Technological advancements create productivity gains, leading to economic expansion. 2. Creative Destruction o Schumpeter introduced the concept of “Creative Destruction”, which means old industries collapse as new technologies replace them. o 📌 Example: The Rise of Smartphones o Traditional mobile phones (Nokia, Blackberry) dominated in the early 2000s. o Apple’s iPhone (2007) revolutionized the market, making touchscreens and apps essential. o Today, smartphones have almost entirely replaced traditional mobile phones and landlines.
- 4. Schumpeter’s Ideology on Innovation Concept Explanation Innovation as the Driver of Growth Economic progress is primarily driven by technological advancements. Entrepreneurs as Change Agents Entrepreneurs introduce new technologies, leading to economic transformations. Creative Destruction Old industries and firms decline as new innovations replace them. Cyclical Growth Pattern Innovation occurs in waves, creating economic booms and recessions. Joseph Schumpeter (1883–1950) was an Austrian economist who argued that technological progress is the engine of economic growth. Unlike classical economists who focused on capital and labor, Schumpeter emphasized innovation and entrepreneurship as key drivers of economic development. Key Ideas of Schumpeter’s Theory:
- 5. The Process of Creative Destruction Schumpeter introduced the term “Creative Destruction”, which refers to the continuous cycle where new technologies disrupt and replace older industries, leading to economic renewal and progress. Steps in the Process of Creative Destruction: • Innovation: A new technology or product is introduced. • Growth and Adoption: The innovation gains traction, attracting investment and consumers. • Displacement of Old Industries: Older businesses decline as new technology takes over. • Economic Transformation: The economy shifts towards newer industries, leading to job creation and productivity gains. • Repeat Cycle: A new innovation emerges, continuing the process.
- 6. Schumpeter’s Three Stages of Technological Change Stage Description Example: Light Bulb 1. Invention Discovery of a new technology Thomas Edison invents the electric light bulb (1879) 2. Innovation Applying and commercializing the invention Edison establishes General Electric (GE) and mass-produces light bulbs 3. Diffusion Widespread adoption of the innovation Cities and homes worldwide switch from gas lamps to electric lighting Schumpeter described technological change as a three-step process: 📊 Chart: The Three Stages of Technological Change Over Time • The invention phase is slow. • The innovation phase accelerates as businesses invest. • The diffusion phase leads to mass adoption and economic transformation.
- 7. Role of Entrepreneurs in Innovation Entrepreneur Company Disruptive Innovation Elon Musk Tesla Electric vehicles (EVs) replacing gasoline cars Steve Jobs Apple iPhone, App Store, digital music Jeff Bezos Amazon E-commerce replacing traditional retail Mark Zuckerberg Meta (Facebook) Social media revolution Entrepreneurs are key drivers of technological change. They introduce disruptive innovations that transform industries.
- 8. Schumpeterian Waves of Innovation Wave Time Period Key Innovations Creative Destruction Examples 1st Wave 1780s–1840s Steam engines, textile industry Manual weaving replaced by mechanized looms 2nd Wave 1850s–1890s Railways, steel, telegraphs Horse-drawn transport declines 3rd Wave 1900s–1940s Automobiles, electricity Decline of coal power, gas lamps 4th Wave 1950s–1990s Computers, electronics, internet Typewriters replaced by PCs 5th Wave 2000s–Present AI, renewable energy, digital economy Traditional banking challenged by fintech
- 10. Why Schumpeter’s Ideas Still Matter Technological change is the most important driver of economic growth. 🔹 Creative destruction ensures that economies evolve and improve. 🔹 Entrepreneurs play a crucial role in introducing innovations. 🔹 Schumpeter’s waves of innovation explain how economies grow in cycles. 📌 What’s Next? The 6th Wave of Innovation could be driven by: • Quantum computing️🖥️ • Biotechnology & AI 🧬 • Sustainable energy & automation 🌍
- 11. Invention
- 12. Invention • An invention is the creation of a new product, process, or idea that did not previously exist. It typically results from scientific research, technological advancements, or experimentation. • Characteristics of Invention • ✔ Novelty – The invention must be new and not previously known. Originality – It must be a unique idea or solution. ✔ Scientific or Technical Basis – Inventions are often based on rigorous ✔ research and experimentation. • 📌 Example: The Wright Brothers’ Airplane (1903) • Orville and Wilbur Wright developed the first powered aircraft in 1903. • Their airplane, the Wright Flyer, flew for 12 seconds and revolutionized human transportation. • This invention led to the modern aviation industry, valued at $800 billion globally today.
- 13. Year Aviation Milestone 1903 First powered flight (Wright Flyer) 1927 First transatlantic flight (Charles Lindbergh) 1958 Introduction of commercial jet airliners 1969 First human moon landing (Apollo 11) 2000s Rise of low-cost airlines (Ryanair, Southwest) 2020s Advancements in electric and AI-powered aircraft
- 14. Role of R&D in Invention Research and Development (R&D) is the systematic process of studying, designing, and improving new technologies. It is the foundation of invention. Two Types of Research in R&D Type of Research Definition Example Basic Research Expands knowledge with no immediate commercial goal Studying quantum mechanics Applied Research Focuses on practical uses of scientific discoveries Developing self-driving cars Experimental Development Creating prototypes and testing inventions Tesla’s first electric vehicle
- 15. Patents and Intellectual Property A patent is a legal right granted to inventors, giving them exclusive ownership of their invention for 20 years. Why Are Patents Important? 🔹 Encourage innovation – Inventors can profit from their ideas. 🔹 Prevent copying – Competitors cannot use patented technology without permission. 🔹 Drive economic growth – Companies invest in R&D when they can protect their inventions.
- 17. Innovation
- 18. Innovation Innovation is the process of transforming an invention into a marketable product, service, or process that adds value. Key Features of Innovation • ✔ Practical Application – Unlike inventions, innovations must have real-world use. ✔ Commercialization – Innovations generate economic or societal impact. ✔ Continuous Improvement – Innovations evolve over time through refinement.
- 19. Stages from Invention to Innovation (Internet Example) Stage Year Development Invention 1960s ARPANET (military use) Early Adoption 1980s Universities and researchers begin using it Innovation 1990s World Wide Web and public internet access Diffusion 2000s–2020s Global adoption, social media, e-commerce
- 21. Incremental vs. Disruptive Innovation Incremental Innovation • 🔹 Small, continuous improvements in existing products or processes. 📌 Example: Smartphone Cameras • Each year, iPhone and Samsung improve camera quality, but the core product remains the same. Disruptive Innovation • 🔹 Radical breakthroughs that transform industries. 📌 Example: Blockchain in Finance • Traditional banking relies on centralized control. • Blockchain (Bitcoin, Ethereum) eliminates the need for intermediaries. • Potential impact: Decentralized finance (DeFi) could replace banks in transactions
- 22. Rogers' Five Attributes of Technological Innovation • ' Diffusion of Innovation Theory (1962) Attribute Definition Example Relative Advantage Is it better than existing alternatives? EVs are cheaper to maintain than gas cars Compatibility Does it fit with current needs? Smartphones fit modern communication habits Complexity Is it easy to use? Social media is user- friendly, while AI tools can be complex Trialability Can it be tested before full adoption? Free trials for Netflix, test drives for EVs Observability Are benefits visible to others? EV users show lower fuel costs, encouraging adoption
- 25. Diffusion Diffusion is the process by which an innovation spreads across industries and societies over time. It determines how quickly and widely new technology is adopted. Key Factors Affecting Diffusion • ✔ Technology's usefulness and affordability ✔ Availability of infrastructure ✔ Government support and regulations 📌 Example: Smartphone Adoption in Pakistan • 2000s: Feature phones dominated (e.g., Nokia 3310). • 2010s: Smartphones became affordable, leading to mass adoption. • 2020s: Pakistan has 190+ million mobile connections, with smartphone penetration over 55%.
- 27. The Diffusion Process Follows an S-Curve Technological adoption does not happen overnight. It follows a predictable pattern: 1 Early Adoption Phase (Slow Growth) 2 Rapid Growth Phase (Majority Adoption) 3 Saturation Phase (Late Adopters/Laggards) 📌 Example: 3G/4G Internet Adoption in Pakistan • 2014: 3G/4G launched in Pakistan. Adoption was slow at first due to high costs. • 2016–2020: Rapid growth as prices dropped and smartphones became cheaper. • 2021–2023: Over 120 million mobile broadband users (saturation phase).
- 28. Barriers to Diffusion Even when technology is beneficial, several barriers can slow down diffusion. 1. High Costs • 📌 Example: Electric Vehicles (EVs) in Pakistan • EVs are expensive, with limited charging stations. • Government incentives (duty reductions) aim to boost adoption. 2. Resistance to Change • 📌 Example: E-learning Adoption • Many universities hesitated to shift to online learning during COVID-19. • Faculty and students struggled with digital adaptation. 3. Infrastructure Issues • 📌 Example: Internet Connectivity in Rural Pakistan • Urban areas have high-speed internet, while rural areas face connectivity issues. • 5G rollout is delayed due to poor infrastructure in remote areas. 4. Government Regulations • 📌 Example: Cryptocurrency Ban in Pakistan • Bitcoin and crypto transactions were banned due to regulatory concerns. • This prevented mass adoption, unlike countries like El Salvador, where Bitcoin is legal tender.
- 29. Robert Solow and Technology in Economic Growth
- 30. Robert Solow’s Growth Model Robert Solow developed the Neoclassical Growth Model (1956), which explains how capital accumulation, labor, and technological progress contribute to economic growth. Insights from the Model • In the short run: Growth is driven by capital investment and labor force expansion. • In the long run: Technology is the key driver of sustained economic growth. • Diminishing Returns to Capital: Simply increasing capital (factories, machines) has limited effects on growth.
- 31. The Solow Residual Economic growth comes from three factors: o Capital (K) – Factories, machines, infrastructure. o Labor (L) – Workforce size and skills. o Technology (A) – Innovation, efficiency, and automation. The Solow Residual measures growth that cannot be explained by capital or labor and is attributed to technological progress. • 📌 Formula: Y=A F(K,L) ⋅ where A (Solow Residual) represents technological progress. Note: Pakistan’s IT Sector (2010–2023) o Investment in IT startups (capital) and skilled labor (human capital) contributed to GDP growth. o However, productivity gains from AI, automation, and cloud computing were unexplained by capital or labor alone → This is the Solow Residual.
- 32. How Does Technology Boost Productivity? Technology enhances economic productivity by: ✔ Improving efficiency (e.g., automation reducing costs). Enabling ✔ new industries (e.g., e-commerce). Increasing ✔ output per worker (e.g., digital banking).
- 33. Criticism of the Solow Growth Model Despite its importance, the Solow model has some limitations: 1. Does Not Explain How Innovation Happens • The model assumes technological progress is external ("exogenous"), but it does not explain what drives innovation. • Alternative Theory: Endogenous Growth Theory (Paul Romer) suggests that R&D, education, and entrepreneurship drive technological progress. • 📌 Example: Pakistan’s Startup Ecosystem • The Solow model cannot explain why some startups (Careem) succeed while others fail. • Romer’s approach: Investment in education, digital skills, and R&D leads to innovation. 2. Assumes Diminishing Returns to Capital • Real-world examples (e.g., China’s long-term growth) show that capital investment + technology can sustain high growth. • 📌 Example: China’s Belt and Road Initiative (BRI) vs. Pakistan’s CPEC • Solow predicts diminishing returns from CPEC infrastructure projects. • But if technology, skills, and innovation improve, Pakistan can sustain higher growth. 3. Ignores Human Capital and Institutions • Solow focuses only on capital and labor. • Modern growth economists emphasize education, governance, and entrepreneurship. • 📌 Example: Education Reform in Pakistan • Countries like South Korea invested in education and technology → sustained economic growth. • Pakistan needs stronger STEM education, R&D funding, and business innovation policies.
- 34. Solow, Technology, and Pakistan’s Economic Growth Solow’s Model explains long-term growth but does not fully explain innovation. ✔ The Solow Residual shows that technology is a major driver of economic progress. ✔ Pakistan needs investment in technology, AI, and human capital to sustain high growth. ✔ Combining Solow’s Model with Endogenous Growth Theories can create a better growth strategy for Pakistan.
- 36. Linear Model of Innovation describes a sequential process where innovation moves step by step from research to market adoption. 📌 Stages of the Linear Model: • Basic Research → Expanding knowledge (e.g., discovery of semiconductors). • Applied Research → Practical use (e.g., developing silicon chips). • Development → Prototype creation (e.g., first microprocessor). • Production → Mass manufacturing (e.g., Intel chips). • Market Adoption → Commercial success (e.g., laptops, smartphones)
- 38. Weaknesses of the Linear Model Although widely used, the Linear Model has limitations: • Ignores Market Feedback o It assumes innovation flows in one direction, but in reality, users shape innovation. o Example: Ride-hailing services (Uber, Careem) evolved by integrating customer feedback. • Rigid Process o Not suitable for fast-changing industries like software and AI. o Example: Pakistan’s Fintech Startups (JazzCash, Easypaisa) evolve quickly, unlike traditional banks. • Slow Adoption o Pakistan’s agriculture sector struggles with slow tech diffusion due to a linear R&D model.
- 39. Feature Linear Model Real-World Innovation Feedback from Users ❌ No ✅ Yes Speed ⏳ Slow ⚡ Fast Flexibility ❌ Low ✅ High Market-driven ❌ No ✅ Yes
- 40. Technological Change Model The Technological Change Model is a non-linear approach where innovation happens through collaboration, feedback, and iteration rather than a strict step-by-step process. 📌 Key Features: ✔ Dynamic & Iterative – Ideas evolve based on user needs. ✔ Feedback-driven – Market feedback shapes new versions. ✔ Collaboration & Experimentation – Universities, firms, and consumers contribute.
- 41. Open Innovation Companies no longer rely only on in-house R&D but instead collaborate with external experts, startups, universities, and users. 📌 Key Aspects of Open Innovation: ✔ Crowdsourcing ideas. ✔ University partnerships (e.g., research grants). ✔ Startup collaboration (e.g., accelerators).
- 43. Key Future Technologies Driving Change ✔ Artificial Intelligence (AI): Automating decision-making, improving efficiency. ✔ Robotics: Enhancing manufacturing, healthcare, and service industries. ✔ Green Technology: Renewable energy, electric vehicles (EVs), sustainable agriculture. ✔ Quantum Computing: Revolutionizing data processing and cybersecurity. 📌 Example: AI-Powered Services in Pakistan • Banking: AI chatbots in HBL and UBL. • E-commerce: AI-driven recommendations on Daraz. • Education: AI tutors for personalized learning (Maqsad).
