Dependencies and consequences

Economies are networks of sectors, households, firms, governments and financial institutions linked by flows of goods, labour, money and information. A shock to one part moves through these links. This page sets out the causal, physical, economic, social and ecological links between economic development and other systems, as part of the field overview.

01Transmission channels

How shocks move through an economy.

ChannelMechanismTypical consequence
Supply chainsLoss of output in one sector reduces inputs for othersProduction falls in sectors far from the original shock
PricesFood, fuel and import prices riseReal incomes fall, especially for poorer households
Labour marketsFirms reduce hours or closeUnemployment and informal work increase
Public financeRevenues fall while spending needs riseDeficits widen and investment is cut
FinanceCredit tightens and capital leavesFirms and governments cannot fund recovery

05Social consequences

Who bears the costs.

Households

Coping and poverty traps

Selling assets or cutting education to cope can lower future income, creating poverty traps.

Places

Regional divergence

Shocks concentrated in particular regions can leave lasting gaps. See regional economic development.

Stability

Social cohesion

Rapid falls in living standards can strain trust in institutions, studied with Society and Human Development.

06Amplifiers and modelling

Why effects compound, and how they are studied.

Shocks compound when buffers are thin: low savings, high debt, little fiscal space and weak social protection. They also compound when they arrive together, so the economy has no time to recover between them. Feedback loops, such as falling demand causing further layoffs, can turn a moderate shock into a recession.

Modelling uses input-output and network methods from network science and contagion and agent-based methods from complex systems and agent-based modelling, developed with Systems Science and Modelling. At The Global Risks Alliance (GRA), Public Finance and Sovereign Debt builds industry understanding of how these pressures reach sovereign debt.

07Questions

Questions and answers.

Which channel matters most?
It depends on the economy. For import-dependent economies, prices are often the fastest channel; for commodity exporters, export revenues and public finance.
Can models predict a recession?
Models help explain transmission and test scenarios. They do not reliably predict timing, and results are presented with uncertainty.
Where are the methods documented?
In the platform's research and evidence pages as they are published.
Why do poorer households suffer most from shocks?
Because they spend more of their income on essentials, have fewer savings and assets, and often work in sectors most exposed to disruption.
