Growth Policies for the High-Income Countries

For the high-income countries, the challenge of economic growth is to push continually for a more educated workforce that can create, invest in, and apply new technologies. In effect, the goal of their growth-oriented public policy is to shift their aggregate supply curves to the right (refer to The Aggregate Demand/Aggregate Supply Model). The main public policies targeted at achieving this goal are fiscal policies focused on investment, including investment in human capital, in technology, and in physical plant and equipment. These countries also recognize that economic growth works best in a stable and market-oriented economic climate. For this reason, they use monetary policy to keep inflation low and stable, and to minimize the risk of exchange rate fluctuations, while also encouraging domestic and international competition.

However, early in the second decade of the 2000s, many high-income countries found themselves more focused on the short term than on the long term. The United States, Western Europe, and Japan all experienced a combination of financial crisis and deep recession, and the after-effects of the recession—like high unemployment rates—seemed likely to linger for several years. Most of these governments took aggressive, and in some cases controversial, steps to jump-start their economies by running very large budget deficits as part of expansionary fiscal policy. These countries must adopt a course that combines lower government spending and higher taxes.

Similarly, many central banks ran highly expansionary monetary policies, with both near-zero interest rates and unconventional loans and investments. For example, in 2012, Shinzo Abe (see Figure), then newly-elected Prime Minister of Japan, unveiled a plan to pull his country out of its two-decade-long slump in economic growth. It included both fiscal stimulus and an increase in the money supply. The plan was successful in some ways and unsuccessful in others. While real GDP growth in Japan has averaged around 1% since 2012 (and was only 0.2% in 2014 and 0.7% in 2016) and while the inflation rate has struggled to stay positive in recent years, the unemployment rate continued to decline through the 2010s. By early 2020, prior to the pandemic, the unemployment rate stood at just 2.5%. Public debt has also reached a plateau in the last 5–7 years of about 230–240% of GDP, although this number did increase slightly in 2020 due to the pandemic. Shinzo Abe stepped down as Prime Minister of Japan in 2020, and was assassinated in 2022.

As we discussed in other chapters, macroeconomics needs to have both a short-run and a long-run focus. The challenge for many of the developed countries in the next few years will be to grapple with the consequences of the pandemic. With high unemployment and no end of the virus containment in sight, it will be challenging for these governments to refocus their efforts on new technology, education, and physical capital investment.

Growth Policies for the Middle-Income Economies

The world’s great economic success stories in the last few decades began in the 1970s with that group of nations sometimes known as the East Asian Tigers: South Korea, Thailand, Malaysia, Indonesia, and Singapore. The list sometimes includes Hong Kong and Taiwan, although often under international law they are treated as part of China, rather than as separate countries. The economic growth of the Tigers has been phenomenal, typically averaging 5.5% real per capita growth for several decades. In the 1980s, other countries began to show signs of convergence. China began growing rapidly, often at annual rates of 8% to 10% per year. India began growing rapidly, first at rates of about 5% per year in the 1990s, but then higher still in the first decade of the 2000s.

We know the underlying causes of these rapid growth rates:

• China and the East Asian Tigers, in particular, have been among the highest savers in the world, often saving one-third or more of GDP as compared to the roughly one-fifth of GDP, which would be a more typical saving rate in Latin America and Africa. These countries harnessed higher savings for domestic investment to build physical capital.
• These countries had policies that supported heavy investments in human capital, first building up primary-level education and then expanding secondary-level education. Many focused on encouraging math and science education, which is useful in engineering and business.
• Governments made a concerted effort to seek out applicable technology, by sending students and government commissions abroad to look at the most efficient industrial operations elsewhere. They also created policies to support innovative companies that wished to build production facilities to take advantage of the abundant and inexpensive human capital.
• China and India in particular also allowed far greater freedom for market forces, both within their own domestic economies and also in encouraging their firms to participate in world markets.

This combination of technology, human capital, and physical capital, combined with the incentives of a market-oriented economic context, proved an extremely powerful stimulant to growth. Challenges that these middle-income countries faced are a legacy of government economic controls that for political reasons can be dismantled only slowly over time. In many of them, the government heavily regulates the banking and financial sector. Governments have also sometimes selected certain industries to receive low-interest loans or government subsidies. These economies have found that an increased dose of market-oriented incentives for firms and workers has been a critical ingredient in the recipe for faster growth.

Growth Policies for Economically-Challenged Countries

Many economically-challenged or low-income countries are geographically located in Sub-Saharan Africa. Other pockets of low income are in the former Soviet Bloc, and in parts of Central America and the Caribbean.

There are macroeconomic policies and prescriptions that might alleviate the extreme poverty and low standard of living. However, many of these countries lack the economic and legal stability, along with market-oriented institutions, needed to provide a fertile climate for domestic economic growth and to attract foreign investment. Thus, macroeconomic policies for low income economies are vastly different from those of the high income economies. The World Bank has made it a priority to combat poverty and raise overall income levels through 2030. One of the key obstacles to achieving this is the political instability that seems to be a common feature of low-income countries.

Figure shows the ten lowest income countries as ranked by The World Bank in 2020. These countries share some common traits, the most significant of which is the recent failures of their governments to provide a legal framework for economic growth. Civil and ethnic wars have impacted Burundi. Command economies, corruption, as well as political factionalism and infighting are commonly adopted elements in these low-income countries. The Democratic Republic of the Congo (often referred to as “Congo”) is a resource-wealthy country that has not been able to increase its subsistence standard of living due to the political environment.

Low-income countries are at a disadvantage because any incomes that people receive are spent immediately on necessities such as food. People in these countries live on less than $1,035 per year, which is less than $100 per month. Lack of saving means a lack of capital accumulation and a lack of loanable funds for investment in physical and human capital. Recent research by two MIT economists, Abhijit Bannerjee and Esther Duflo, has confirmed that the households in these economies are trapped in low incomes because they cannot muster enough investment to push themselves out of poverty.

For example, the average citizen of Burundi, a low-income country, subsists on $239 per year (adjusted to 2020 dollars). According to Central Intelligence Agency data in its CIA Factbook, as of 2021, 85% of Burundi’s population is agrarian, with bananas as the main income producing crop. Only one in two children attends school and, as Figure shows, many are not in schools comparable to what occurs in developed countries. Political instability has made it difficult for Burundi to make significant headway toward growth, as verified by the electrification of only 11% of households and 40% of its national income coming from foreign aid.

Other low-income countries share similar stories. These countries have found it difficult to generate investments for themselves or to find foreign investors willing to put up the money for more than the basic needs. Foreign aid and external investment comprise significant portions of the income in these economies, but are not sufficient to allow for the capital accumulation necessary to invest in physical and human capital. However, is foreign aid always a contributor to economic growth?

Development economics is a branch of economics that often focuses on answering that question and others like it. Development economists analyze the forces and outcomes of economics in developing nations. The field is typically focused on—and sometimes defined as—understanding and implementing policies and practices to improve economic and social wellbeing in low- and middle-income nations or regions. But it is an extremely wide and varied area of study, often blending politics, fiscal policy, education, innovation, health and medicine, international trade, natural resources, and military/geopolitical considerations.

Many development economists have focused on understanding the best mix of approaches to foster equitable and sustainable growth. Like other economists, they may analyze practices or outcomes from the past and apply that knowledge to the present and future. And many prominent development economists challenge traditional ways of thinking. Dambisa Moyo, for example, provides evidence indicating that foreign aid is rarely a positive solution and often does more harm than good. In her book Dead Aid: Why Aid Is Not Working and How There Is Another Way for Africa (2009), she lays out the failure of past aid, indicating that it typically ends up in the pockets of corrupt officials and has the adverse effect of minimizing other types of investment. At the time, Moyo proposed a complete stoppage of foreign aid into Africa. Moyo sees far greater promise in increases in trade and direct private investment, as well as other financing options such as bonds.

Concerns over International Trade in Goods and Services

There is a long list of worries about foreign trade in goods and services: fear of job loss, environmental dangers, unfair labor practices, and many other concerns. We discuss these arguments at some length in the chapter on The International Trade and Capital Flows.

Of all of the arguments for limitations on trade, perhaps the most controversial one among economists is the infant industry argument; that is, subsidizing or protecting new industries for a time until they become established. (Globalization and Protectionism explains this concept in more detail.) Countries have used such policies with some success at certain points in time, but in the world as a whole, support for key industries is far more often directed at long-established industries with substantial political power that are suffering losses and laying off workers, rather than potentially vibrant new industries that are not yet established. If government intends to favor certain industries, it needs to do so in a way that is temporary and that orients them toward a future of market competition, rather than a future of unending government subsidies and trade protection.

Concerns over International Flows of Capital

Recall from The Macroeconomic Perspective that a trade deficit exists when a nation’s imports exceed its exports. In order for a trade deficit to take place, foreign countries must provide loans or investments, which they are willing to do because they expect eventual repayment (that the deficit will become a surplus). A trade surplus, you may remember, exists when a nation’s exports exceed its imports. Thus, in order for a trade deficit to switch to a trade surplus, a nation’s exports must rise and its imports must fall. Sometimes this happens when the currency decreases in value. For example, if the U.S. had a trade deficit and the dollar depreciated, imports would become more expensive. This would, in turn, benefit the foreign countries that provided the loans or investments.

The expected pattern of trade imbalances in the world economy has been that high-income economies will run trade surpluses, which means they will experience a net outflow of capital to foreign destinations or export more than they import, while low- and middle-income economies will run trade deficits, which means that they will experience a net inflow of foreign capital.

This international investing pattern can benefit all sides. Investors in the high-income countries benefit because they can receive high returns on their investments, and also because they can diversify their investments so that they are at less risk of a downturn in their own domestic economy. The low-income economies that receive an inflow of capital presumably have potential for rapid catch-up economic growth, and they can use the international financial capital inflow to help spur their physical capital investment. In addition, financial capital inflows often come with management abilities, technological expertise, and training.

However, for the last couple of decades, this cheerful scenario has faced two “dark clouds.” The first cloud is the very large trade or current account deficits in the U.S. economy. (See The International Trade and Capital Flows.) Instead of offering net financial investment abroad, the U.S. economy is soaking up savings from all over the world. These substantial U.S. trade deficits may not be sustainable according to Sebastian Edwards writing for the National Bureau of Economic Research. While trade deficits on their own are not bad, the question is whether governments will reduce them gradually or hastily. In the gradual scenario, U.S. exports could grow more rapidly than imports over a period of years, aided by U.S. dollar depreciation. An unintended consequence of the slow growth since the Great Recession has been a decline in the U.S. current account deficit's from 6% pre-recession to 3% most recently.

The other option is that the government could reduce the U.S. trade deficit in a rush. Here is one scenario: if foreign investors became less willing to hold U.S. dollar assets, the dollar exchange rate could weaken. As speculators see this process happening, they might rush to unload their dollar assets, which would drive the dollar down still further.

A lower U.S. dollar would stimulate aggregate demand by making exports cheaper and imports more expensive. It would mean higher prices for imported inputs throughout the economy, shifting the short-term aggregate supply curve to the left. The result could be a burst of inflation and, if the Federal Reserve were to run a tight monetary policy to reduce the inflation, it could also lead to recession. People sometimes talk as if the U.S. economy, with its great size, is invulnerable to this sort of pressure from international markets. While it is difficult to rock, it is not impossible for the $17 trillion U.S. economy to face these international pressures.

The second “dark cloud” is how the smaller world economies should deal with the possibility of sudden foreign financial capital inflows and outflows. Perhaps the most vivid recent example of the potentially destructive forces of international capital movements occurred in the East Asian Tiger economies in 1997–1998. Thanks to their excellent growth performance over the previous few decades, these economies had attracted considerable interest from foreign investors. In the mid-1990s, however, foreign investment into these countries surged even further. Much of this money funneled through banks that borrowed in U.S. dollars and loaned in their national currencies. Bank lending surged at rates of 20% per year or more. This inflow of foreign capital meant that investment in these economies exceeded the level of domestic savings, so that current account deficits in these countries jumped into the 5–10% GDP range.

The surge in bank lending meant that many banks in these East Asian countries did not do an especially good job of screening out safe and unsafe borrowers. Many of the loans—as high as 10% to 15% of all loans in some of these countries—started to turn bad. Fearing losses, foreign investors started pulling out their money. As the foreign money left, the exchange rates of these countries crashed, often falling by 50% or more in a few months. The banks were stuck with a mismatch: even if the rest of their domestic loans were repaid, they could never pay back the U.S. dollars that they owed. The banking sector as a whole went bankrupt. The lack of credit and lending in the economy collapsed aggregate demand, bringing on a deep recession.

If the flow and ebb of international capital markets can flip even the economies of the East Asian Tigers, with their stellar growth records, into a recession, then it is no wonder that other middle- and low-income countries around the world are concerned. Moreover, similar episodes of an inflow and then an outflow of foreign financial capital have rocked a number of economies around the world: for example, in the last few years, economies like Ireland, Iceland, and Greece have all experienced severe shocks when foreign lenders decided to stop extending funds. Especially in Greece, this caused the government to enact austerity measures which led to protests throughout the country (Figure).

Many nations are taking steps to reduce the risk that their economy will be injured if foreign financial capital takes flight, including having their central banks hold large reserves of foreign exchange and stepping up their regulation of domestic banks to avoid a wave of imprudent lending. The most controversial steps in this area involve whether countries should try to take steps to control or reduce the flows of foreign capital. If a country could discourage some speculative short-term capital inflow, and instead only encourage investment capital that it committed for the medium and the long term, then it could be at least somewhat less susceptible to swings in the sentiments of global investors.

If economies participate in the global trade of goods and services, they will also need to participate in international flows of financial payments and investments. These linkages can offer great benefits to an economy. However, any nation that is experiencing a substantial and sustained pattern of trade deficits, along with the corresponding net inflow of international financial capital, has some reason for concern. During the Asian Financial Crisis in the late 1990s, countries that grew dramatically in the years leading up to the crisis as international capital flowed in, saw their economies collapse when the capital very quickly flowed out.

Market-Oriented Economic Reforms

The standard of living has increased dramatically for billions of people around the world in the last half century. Such increases have occurred not only in the technological leaders like the United States, Canada, the nations of Europe, and Japan, but also in the East Asian Tigers and in many nations of Latin America and Eastern Europe. The challenge for most of these countries is to maintain these growth rates. The economically-challenged regions of the world have stagnated and become stuck in poverty traps. These countries need to focus on the basics: health and education, or human capital development. As Figure illustrates, modern technology allows for the investment in education and human capital development in ways that would have not been possible just a few short years ago.

Other than the issue of economic growth, the other three main goals of macroeconomic policy—that is, low unemployment, low inflation, and a sustainable balance of trade—all involve situations in which, for some reason, the economy fails to coordinate the forces of supply and demand. In the case of cyclical unemployment, for example, the intersection of aggregate supply and aggregate demand occurs at a level of output below potential GDP. In the case of the natural rate of unemployment, government regulations create a situation where otherwise-willing employers become unwilling to hire otherwise-willing workers. Inflation is a situation in which aggregate demand outstrips aggregate supply, at least for a time, so that too much buying power is chasing too few goods. A trade imbalance is a situation where, because of a net inflow or outflow of foreign capital, domestic savings are not aligned with domestic investment. Each of these situations can create a range of easier or harder policy choices.
