To curb the spread of disease during a
pandemic, governing authorities in countries
around the world implement lockdown
measures, shut down businesses, and reduce
economic activity.
 The results are higher levels of unemployment
from a national perspective and less economic
exchange from a global perspective.
Closing country borders, shuttering workplaces,
and limiting distribution in supply chains slow
much of the global economy.

In the context of the coronavirus pandemic, the International
Monetary Fund (2020) calls country interventions the 
Great Lockdown
:
 
The extensive measures that reduce disease contagion and save
 
lives.
 When global shocks occur, such as pandemics, the economic
outcomes take years to unfold, often spiraling in unpredictable
directions.

On a global scale, a pandemic creates public
health and economic costs.
 The crisis in public health requires a reduction
in global economic activity.
 According to the IMF (2020), several factors
signal the severity of a global shock, including
the nature of the shock, amplification channels,
early indicators, and changes in commodity
prices.

NATURE OF THE SHOCK
 
 
The nature of the shock determines
the length and severity of the global
economic downturn.
 
AMPLIFICATION CHANNELS
 
 
The shock associated with a global
pandemic amplifies through familiar
channels.

During a pandemic, tracking the global
economy reveals both economic trends
and the potential for correlation between
economic variables.
 
Several variables inform a pandemic
economy tracker:
Mobility and economic performance
Speed of intervention
Size of the economy
Capital markets
Developing country status
PANDEMIC ECONOMICS 12

MOBILITY AND ECONOMIC PERFORMANCE
 
 
The loss of mobility relates to changes
in economic activity.
 
SPEED OF INTERVENTION
 
 
The more extensive, decisive, and
expedient are intervention policies,
the slower is the spread of infections.
PANDEMIC ECONOMICS 12
10
 
 
SIZE OF ECONOMY
 
 
Using business cycle terminology, the
contractionary interval is brief for
some countries and longer for others.
 
CAPITAL MARKETS
 
 
Intervention policies lead to economic
contraction.  The reaction of capital
markets reveals market expectations.
PANDEMIC ECONOMICS 12

DEVELOPING COUNTRY STATUS
 
 
Countries may struggle through
subsequent infection waves if they
allocate fewer resources to identify,
track, and isolate infections.

The model of a trading economy by Krugman et
al. (2018) demonstrates the impact of economic
contraction.
 It uses several relationships:
Production possibilities and supply
Relative prices and demand
Terms of trade and country welfare
Relative supply, relative demand, and global
equilibrium
Contraction and the production possibility frontier

 Assume trade between two countries.
 Each country produces two forms of output, goods (
G
) and services (
S
).
 Each possesses a 
production possibility frontier
 
(PPF), which demonstrates the
maximum level of production, given current economic resources and
technology.

A different 
terms of trade
, defined as the price of an item that the economy
exports divided by the price of the item the economy imports, alters the welfare
effects.
 While the economy is exporting services and importing goods, suppose

 This change in relative prices improves the economy’s competitive position.

 The 
RS
 curve slopes upward because an increase in 
P
S
/
P
G
 encourages suppliers
to produce more.
 The 
RD
 curve slopes downward because an increase in 
P
S
/
P
G
 encourages
consumers to alter their consumption mix with more goods and less services.
 The key in the analysis is that shifts in 
RS
 may show a bias toward goods or
services:
Rightward shift in 
RS
: service-biased growth (more services relative to goods)
Leftward shift in 
RS
: goods-biased growth (more goods relative to services)

 During a global recession, one possibility is that the supply of all forms of
output declines equally so that the relative quantity of services to goods
remains constant.
 Another possibility, relevant for a pandemic, is that a global recession
demonstrates 
biased contraction
 
toward goods.
 That is, the supply of services may decline, but the supply of goods declines
even more.

 Suppose the home economy experiences biased contraction toward
goods, so its production of goods decreases relatively more than its
production of services.
 For the global economy, the production of services relative to goods
rises.

 The study of 
development economics
 
addresses
the efficient allocation of scarce or idle
resources and the economic, institutional, and
social mechanisms, private and public, necessary
to bring about improvements in human well-
being.
 A focus on developing economies makes clear
that the effects of a global pandemic are not

 The World Bank, an international financial institution that provides grants and
loans, uses data on gross national income per capita in current U.S. dollars to
classify economies according to four income groups:
high income
upper-middle income
lower-middle income
low income
 
Economies in classifications other than high income are considered developing.

Developing countries possess a range of characteristics with economic activity,
social structure, language, tradition, history, culture, and political systems.
 While the characteristics may differ by degree, they exist as reasons why the
status of “developing” persists.
 Characteristics of developing countries include:
relatively lower living standards
lower levels of productivity
higher rates of population growth and dependency burden
greater percentage of work in the informal sector
dependence and vulnerability in international relations

Developing countries are in a difficult position to respond to a global shock.
 Like developed countries, they suffer from economic contraction, lockdown
measures, and rising infections.
 But lower living standards, lower levels of productivity, higher population
growth rates, large informal sectors, and relatively weaker positions in the global
economic order constrain the capacity of developing countries to address these
problems in a comprehensive manner.

  14. Production Possibilities and Supply Production Possibilities and Supply Assume trade between two countries. Each country produces two forms of output, goods (G) and services (S). Each possesses a production possibility frontier(PPF), which demonstrates the maximum level of production, given current economic resources and technology. 14 PANDEMIC ECONOMICS 12

  16. Production and Isovalue Lines Production and Isovalue Lines Production depends on the ratio of the price of services (PS) to goods (PG): PS/PG In the absence of external effects, market power, and other forms of market failure, an efficient economy maximizes the value of output: Along isovalue lines, the value of output is constant: PSQS + PGQG But when V increases, the isovalue line shifts away from the origin: V = PSQS + PGQG (V2 > V1 > V0) 16 PANDEMIC ECONOMICS 12

  17. Case One: Full Employment Production Case One: Full Employment Production A change in relative prices leads to two outcomes. It alters the slope of the isovalue line and determines a new production bundle. Suppose PS/PG rises, increasing the slope of V1. 17 PANDEMIC ECONOMICS 12

  18. The new isovalue line (V11) moves the production bundle from point a to point b. As the relative price of services increases, the economy produces more services and fewer goods. 18 PANDEMIC ECONOMICS 12

  19. Relative Prices and Demand Relative Prices and Demand The value of an economy s production equals the value of its consumption: V = PSQS + PGQG = PSDS + PGDG, where DS and DG represent the consumption of services and goods Consumption and production lie on the same isovalue line. Consumption depends on consumer tastes and preferences, which are represented by indifference curves (I1 , In). Along an indifference curve, the consumption of goods and services leaves consumers equally well off. 19 PANDEMIC ECONOMICS 12

  20. The economy maximizes welfare and consumes at point c, where the isovalue line is tangent to I1. The economy produces at point a and consumes at point c The economy exports services (measured along the horizontal axis) and imports goods (measured along the vertical axis). 20 PANDEMIC ECONOMICS 12

  21. Terms of Trade and Country Welfare Terms of Trade and Country Welfare A different terms of trade, defined as the price of an item that the economy exports divided by the price of the item the economy imports, alters the welfare effects. While the economy is exporting services and importing goods, suppose PS/PG increases. This change in relative prices improves the economy s competitive position. 21 PANDEMIC ECONOMICS 12

  22. When PS/PGincreases, V1 rotates to V11. An increase in the terms of trade raises the economy s welfare. When PS/PG increases, the economy moves from point c to point d on a higher indifference curve (I2). 22 PANDEMIC ECONOMICS 12

  23. Global Equilibrium Global Equilibrium The determination of an equilibrium depends on global relative supply (RS) and global relative demand (RD). Suppose a home economy and a foreign economy. The home economy exports services and the foreign economy exports goods. 23 PANDEMIC ECONOMICS 12

  24. Production and Terms of Trade Production and Terms of Trade The production of goods and services by the home economy is represented by QG and QS, respectively. The terms of trade PS/PG applies to the home economy. The production of good and services in the foreign economy is represented by QG* and QS*, respectively. The terms of trade PG/PS applies to the foreign economy. The global relative supply of and relative demand for services determines both the terms of trade, PS/PG, and the relative quantity of services (RQS): QS + QS*/QG + QG* 24 PANDEMIC ECONOMICS 12

  25. Global Relative Supply and Demand Global Relative Supply and Demand The RS curve slopes upward because an increase in PS/PG encourages suppliers to produce more. The RD curve slopes downward because an increase in PS/PG encourages consumers to alter their consumption mix with more goods and less services. The key in the analysis is that shifts in RS may show a bias toward goods or services: Rightward shift in RS: service-biased growth (more services relative to goods) Leftward shift in RS: goods-biased growth (more goods relative to services) 25 PANDEMIC ECONOMICS 12

  27. Case Two: Recession During a Pandemic Case Two: Recession During a Pandemic A global recession reduces economic activity but is not evenly distributed. In the model, a difference between goods and services alters the composition of production. 27 PANDEMIC ECONOMICS 12

  28. Contraction and the PPF Contraction and the PPF During a global recession, one possibility is that the supply of all forms of output declines equally so that the relative quantity of services to goods remains constant. Another possibility, relevant for a pandemic, is that a global recession demonstrates biased contractiontoward goods. That is, the supply of services may decline, but the supply of goods declines even more. 28 PANDEMIC ECONOMICS 12

  29. The PPF shifts inward more in one direction (goods) than the other (services). The economy operates on a lower isovalue line (V0) and the production bundle moves from point a to point e. 29 PANDEMIC ECONOMICS 12

  30. Relative Supply and the Terms of Trade Relative Supply and the Terms of Trade Suppose the home economy experiences biased contraction toward goods, so its production of goods decreases relatively more than its production of services. For the global economy, the production of services relative to goods rises. 30 PANDEMIC ECONOMICS 12

  31. The global relative supply curve shifts to the right from RS1 to RS2, decreasing the relative price of services from (PS/PG)1 to (PS/PG)2 and increasing the relative quantity of services from RQS1 to RQS2. This import-biased contractionreduces an economy s ability to import goods, which may exacerbate shortages during a pandemic. 31 PANDEMIC ECONOMICS 12

  32. The study of development economicsaddresses the efficient allocation of scarce or idle resources and the economic, institutional, and social mechanisms, private and public, necessary to bring about improvements in human well- being. 5.

Economics of Developing of Developing Countries Countries A focus on developing economies makes clear that the effects of a global pandemic are not equally distributed. 32 PANDEMIC ECONOMICS 12

  33. World Bank Income Classification World Bank Income Classification The World Bank, an international financial institution that provides grants and loans, uses data on gross national income per capita in current U.S. dollars to classify economies according to four income groups: high income upper-middle income lower-middle income low income Economies in classifications other than high income are considered developing. 33 PANDEMIC ECONOMICS 12

  35. Characteristics of Developing Countries Characteristics of Developing Countries Developing countries possess a range of characteristics with economic activity, social structure, language, tradition, history, culture, and political systems. While the characteristics may differ by degree, they exist as reasons why the status of developing persists. Characteristics of developing countries include: relatively lower living standards lower levels of productivity higher rates of population growth and dependency burden greater percentage of work in the informal sector dependence and vulnerability in international relations 35 PANDEMIC ECONOMICS 12

  36. Impact of a Pandemic on Developing Countries Impact of a Pandemic on Developing Countries Developing countries are in a difficult position to respond to a global shock. Like developed countries, they suffer from economic contraction, lockdown measures, and rising infections. But lower living standards, lower levels of productivity, higher population growth rates, large informal sectors, and relatively weaker positions in the global economic order constrain the capacity of developing countries to address these problems in a comprehensive manner. 36 PANDEMIC ECONOMICS 12

  37. Sustainable Development Goals Sustainable Development Goals The goals of sustainable development, established by the United Nations in 2015 as a collection of interdependent aspirations and made actionable in 2017, are designed as a blueprint for a more sustainable future. 37 PANDEMIC ECONOMICS 12
