ECOS2025 East Asian Economies

How ECOS2025 is assessed

What ECOS2025 covers

The guide begins with regional growth and the economic toolkit, then applies those models to Japanese reconstruction and stagnation, Korean industrialisation, Chinese reform, non-standard development policy and the middle-income trap.

Students use the Solow-Swan growth model, growth accounting, exchange-rate theory, saving and investment identities, public-debt dynamics, public choice and game theory to examine historical episodes and contemporary challenges. The country sequence is equally important. Japan supplies cases on Meiji reform, postwar stabilisation, the high-growth era, the asset bubble, prolonged stagnation, public debt and Abenomics.

Korea shows how land reform, security conditions, planning, directed finance, chaebols and export discipline can combine in a developmental state while creating governance and concentration risks.

China shows gradual reform inside a communist political system, household and local incentives, special economic zones, population policy, RMB management, WTO integration and the challenge of sustaining productivity as catch-up becomes harder.

The final policy block compares East Asian non-standard strategies with the Washington Consensus and asks whether middle-income economies can move from capital accumulation toward efficiency, structural change and innovation. Assessment rewards regular engagement as well as examination performance. Lecture participation is worth 5%, tutorial participation 10%, online learning 10%, the Week 8 midterm 25% and the final exam 50%.

The final lasts two hours in the November exam period, includes an essay question and carries a hurdle requiring at least 45% on the exam to pass the unit. The most reliable preparation is therefore broad and cumulative: redraw each model, explain every direction, recompute each numeric example, attach the model to a named country mechanism and finish with a conclusion whose limits are explicit. This guide follows that method.

Its questions are original, while the methods and assessment facts are grounded in the University of Sydney materials for Semester 2 2026.

Worked example · free

Growth accounting with a Solow residual

Key terms

Solow steady state

The long-run position where saving per worker equals required investment, so capital per worker is constant.

Total factor productivity

The efficiency with which measured inputs produce output, represented by A in the production function.

Solow residual

Output growth left after subtracting the weighted contributions of capital and labour growth.

Flying geese hypothesis

A model of industrial upgrading in which production and comparative advantage shift across leader and follower economies.

Purchasing-power parity

A benchmark linking nominal exchange rates to relative price levels through the law of one price.

Real exchange rate

A price-adjusted exchange-rate measure used to assess international competitiveness.

Primary balance

Government revenue minus non-interest spending, used with interest and growth to explain debt dynamics.

Dodge Line

Japan's postwar stabilisation programme combining fiscal discipline, price controls, reform and a fixed exchange rate.

Developmental state

A state that coordinates finance, investment and industrial upgrading while using markets and performance discipline.

Chaebol

A large Korean corporate group that supported scale and exports while raising concentration and governance concerns.

Demographic dividend

Potential growth gains when the working-age population rises relative to dependants.

Dual-track reform

A gradual reform that preserves state obligations while allowing market exchange at the margin.

Second-best policy

Policy designed for an economy where several distortions cannot all be removed at once.

Middle-income trap

The hypothesis that an economy can lose low-cost advantages before gaining high-income innovation capability.

ECOS2025 FAQ

Questions students ask in each ECOS2025 chapter

Why is the phrase East Asian miracle analytically risky?

It can hide differences in timing, institutions and later performance. A stronger answer identifies the mechanism that produced growth and then tests whether the same mechanism operated in each national case. Chapter 01 · East Asian Growth in Context

Does a higher saving rate permanently raise the growth rate?

In the basic Solow model it raises the steady-state level of capital and output per worker. Growth accelerates during transition, but diminishing returns prevent a permanently higher rate without technological progress. Chapter 02 · Growth Models and Productivity

Why do exchange-rate direction errors happen so often?

Students name appreciation before writing the quotation units. A rise has opposite meanings under foreign-per-domestic and domestic-per-foreign conventions, so units must come before the direction word. Chapter 03 · Exchange Rates, Capital Flows and Debt

Why should Meiji reform be treated as a package?

Property, taxation, mobility, education and industry reinforced one another. Isolating one reform hides the sequence through which the state gained revenue and society gained incentives and capabilities. Chapter 04 · Japan Before the Postwar Miracle

Why was stabilisation contractionary at first?

Tighter fiscal and monetary settings reduced demand and inflation, imposing unemployment and deflation before later benefits could appear. That timing is essential when evaluating the programme. Chapter 05 · Japan's Recovery and High-Growth Era

Why is the Plaza Accord an incomplete explanation?

Appreciation explains an external shock but not the domestic policy response, asset bubble, collapse or prolonged balance-sheet, banking and deflation dynamics that made weakness persist. Chapter 06 · Japan's Lost Decades and Abenomics

Why cannot higher colonial-era output settle the development debate?

Aggregate output omits ownership, coercion, political rights and distribution. Capacity can expand while benefits are extracted and human costs rise, so welfare claims require broader evidence. Chapter 07 · Korea's Historical Foundations

Was Korea's strategy free market or central planning?

Neither label is sufficient. Private firms and markets operated within strong state coordination of finance, investment and industrial priorities, with export performance supplying an important discipline. Chapter 08 · Korea's Developmental State

Why must the contributions add back to output growth?

The residual is defined as what remains after weighted input contributions are removed. If the total does not match output growth, the factor share, arithmetic or units are wrong. Chapter 09 · Growth Accounting and Demographic Change

Why is China's reform called experimental?

Policies were tested gradually and locally rather than imposed as one complete national blueprint. That allowed learning, preserved some existing claims and reduced immediate opposition. Chapter 10 · China's Reform and Global Integration

Why did standard reform recipes face criticism?

They often assumed institutional foundations and overlooked coordination or information failures. Removing every distortion at once was neither feasible nor necessarily beneficial when complementary capabilities were missing. Chapter 11 · Non-Standard Development Policy

Does slower growth prove a middle-income trap?

No. Growth can slow through ordinary convergence and diminishing returns. A trap diagnosis needs a consistent income definition, comparative evidence and a mechanism such as weak efficiency or stalled upgrading. Chapter 12 · Escaping the Middle-Income Trap

How to study for the exam

Start revision with a model ledger. For each model, write the variables, equilibrium condition, shift directions, assumptions and one limitation. Redraw the Solow model until saving, population growth and productivity changes are automatic. Recompute the growth-accounting example and make the contributions add back to output growth. For exchange rates, write the quote units before using appreciation or depreciation.

For public debt, keep the primary balance, real interest rate and output growth in separate columns. Next build a country timeline. Japan should be divided into prewar institutional change, postwar stabilisation and recovery, high growth, the bubble and Lost Decades, then Abenomics. Korea should connect historical foundations and land reform to the Park-era coordination system, targeted finance, chaebols and export discipline.

China should separate Mao and Deng, domestic incentive reform and external opening, then add population, RMB and WTO mechanisms. Finish by practising mixed prompts that require both layers. Use the structure claim, model, mechanism, evidence, limitation and conclusion. Mark your own answer by checking whether each noun has a causal verb and whether the final judgment states a country, period and boundary.

In the final week, favour broad retrieval and complete attempts because the final exam carries a 45% hurdle.
