The emergence of digital currencies has sparked profound shifts in economic thought, challenging long-standing theories and prompting urgent academic inquiry. Digital Currency Economic Analysis by Yao Qian and Chen Hua offers a rigorous, systematic exploration of the economic mechanisms behind both private and central bank digital currencies (CBDCs). By applying modern economic frameworks—ranging from game theory to institutional economics—the book fills critical gaps in understanding how digital assets reshape monetary systems, organizational behavior, asset valuation, and policy design.
This comprehensive study not only diagnoses where traditional economic theories fall short but also constructs new analytical tools to guide innovation and regulation in the evolving digital economy.
The Four Silences of Modern Economic Theory
Digital currencies have exposed limitations in classical economic paradigms. Four core areas—monetary theory, organizational behavior, asset pricing, and legal tender frameworks—are struggling to keep pace with technological advancements.
Monetary Theory at a Crossroads
Bitcoin’s decentralized architecture resonates with Carl Menger’s theory of spontaneous monetary order, where money emerges organically through social consensus rather than state decree. Advocates argue that cryptographic consensus replaces government-backed issuance, potentially eliminating inflationary bias and redistribution favoritism. This vision has fueled hopes for a post-state monetary system.
Yet fundamental questions remain unanswered: What truly defines money? Is consensus alone sufficient? Can privately issued tokens fulfill all monetary functions—medium of exchange, store of value, unit of account?
Traditional doctrines—including metallism, chartalism, and Hayek’s “denationalization of money”—fail to fully explain or evaluate these new forms. The digital transformation demands a revised theoretical foundation for understanding what money is and what it could become.

Organizational Behavior Reimagined
Blockchain technology disrupts conventional organizational models. In decentralized ecosystems, there are no boards, hierarchies, or centralized management. Instead, algorithmic governance coordinates actions across global, anonymous participants.
This represents a radical departure from Coasean theories of the firm, where organizations exist to minimize transaction costs. Blockchain introduces a new coordination mechanism—consensus algorithms—that function alongside or even outside price signals.
Key research dimensions include:
- Micro-level: How do Proof-of-Work (PoW) and Proof-of-Stake (PoS) create incentive-compatible environments?
- Meso-level: How does distributed ledger technology (DLT) differ from traditional accounting systems? What implications does this have for corporate governance and financial reporting?
- Industry-level: How should we govern decentralized networks? What mix of on-chain and off-chain, formal and informal rules ensures accountability?
- Macro-level: As algorithmic economies grow, could they evolve into forms resembling centrally planned systems? Understanding the boundaries between markets, firms, and algorithms becomes crucial.
These developments call for an updated theory of economic organization—one that accounts for code-based coordination.
Asset Pricing in Uncharted Territory
The explosive growth of cryptoassets has outpaced valuation methodologies. In 2017, Bitcoin’s surge sparked debate: Was it driven by scarcity, speculative frenzy, or genuine utility?
Unlike traditional assets, crypto tokens often derive value from complex interdependencies. Returns may be denominated in other cryptos, not fiat. Some combine features of commodities, securities, and currencies. Stablecoins add further complexity with engineered pegs and reserve structures.
Applying standard models like Discounted Cash Flow (DCF) becomes problematic without stable risk-free rates or predictable cash flows. Alternative approaches must account for network effects, tokenomics, and technological adoption curves.
The book proposes a five-pronged valuation framework:
- Cost-based pricing (e.g., mining expenses)
- Monetary pricing (comparing to gold or fiat)
- Equity-style valuation (for utility tokens with revenue-sharing)
- Option pricing models
- Arbitrage-free pricing
This structured approach helps investors assess risk, identify bubbles, and understand derivative instruments like Bitcoin futures and ETFs.

The Evolving Role of Legal Tender
As private digital currencies gain traction and cash usage declines, central banks face mounting pressure to digitize sovereign money. But CBDC design involves deep technical and economic trade-offs:
- Architecture: Centralized, decentralized, or hybrid?
- Access model: Account-based or token-based?
- Distribution: One-tier (direct central bank access) or two-tier (via commercial banks)?
- Privacy: How to balance traceability with anonymity?
These choices impact payment efficiency, financial inclusion, monetary transmission, and systemic stability.
Yao Qian advocates a “two-tier” model with “one currency, two repositories, three centers”—a structure that separates issuance, operation, and oversight while ensuring scalability and legal clarity. Crucially, the authors recommend decoupling digital currency from blockchain dependency, favoring flexible DLT integration over rigid technological mandates.
Bridging Theory and Practice: A Framework for Innovation
Rather than rejecting existing economic theory, the book argues for integration. Digital currencies don’t invalidate classical insights—they extend them.
The first half analyzes private digital currencies, examining:
- Game-theoretic foundations of consensus mechanisms
- Contractual nature of tokens and associated principal-agent problems
- Economic implications of decentralized exchanges
- Valuation frameworks and regulatory design for ICOs
The second half turns to central bank digital currencies, offering:
- A Coasean analysis of economic evolution toward algorithmic systems
- A public choice theory-based explanation of monetary evolution
- A full CBDC design blueprint with technical and institutional specifications
- Simulations of macroeconomic impacts using dynamic stochastic general equilibrium (DSGE) modeling
Findings suggest that well-designed CBDCs can enhance financial stability, improve monetary policy effectiveness, and support long-term economic growth—with manageable transition risks.
Frequently Asked Questions
Q: Can Bitcoin replace gold as a store of value?
A: While both are scarce assets, Bitcoin lacks gold’s historical credibility and physical tangibility. Its high volatility limits its reliability as a stable store of value—though its fixed supply appeals to inflation skeptics.
Q: Are stablecoins truly stable?
A: Not always. Algorithmic stablecoins have failed under stress due to design flaws. Only those backed by robust reserves and transparent audits maintain their peg reliably over time.
Q: Will CBDCs eliminate commercial banks?
A: Unlikely under a two-tier system. By channeling distribution through existing financial institutions, CBDCs can coexist with traditional banking while enhancing competition and innovation.
Q: How do consensus mechanisms ensure security?
A: Through economic incentives. PoW deters attacks by making them prohibitively expensive; PoS aligns validator interests with network health by staking real value.
Q: Can algorithmic economies lead to digital planned economies?
A: Potentially—but only if centralized control overrides decentralized decision-making. Properly designed, algorithmic coordination enhances market efficiency without eliminating individual autonomy.
Q: Is now a good time to invest in digital currencies?
A: With proper due diligence. Investors should distinguish between speculative tokens and fundamentally sound projects with clear use cases, sustainable tokenomics, and strong governance.
Toward a New Economic Paradigm
Digital Currency Economic Analysis does more than diagnose theoretical shortcomings—it builds bridges between technology and economics. It calls for collaborative research involving economists, technologists, and policymakers to ensure digital innovation serves public welfare.
As nations advance CBDC pilots—from China’s e-CNY to the ECB’s digital euro—the insights from this work provide essential guidance. Digital currency isn’t just about technology; it’s about reimagining the foundations of trust, exchange, and value in the 21st century.
