Gross Domestic Product

Gross domestic product (GDP) is the value of all the goods and services produced by a country in a single year. Usually quoted in US dollars, the number is an official accounting of the country’s output of goods and services. For example, if a country has a large black, or underground, market for transactions, it will not be included in the official GDP. Emerging-market countries, such as India and Russia, historically have had large black-market transactions for varying reasons, which often meant their GDP was underestimated.

Figure 4.1 shows the total size of the economy, but a company will want to know the income per person, which may be a better indicator of the strength of the local economy and the market opportunity for a new consumer product. GDP is often quoted on a per person basis. Per capita GDP is simply the GDP divided by the population of the country.

The per capita GDP can be misleading because actual costs in each country differ. As a result, more managers rely on the GDP per person adjusted for purchasing power to understand how much income local residents have. This number helps professionals evaluate what consumers in the local market can afford.

Companies selling expensive goods and services may be less interested in economies with low per capita GDP. Figure 4.2 “Per Capita GDP on a Purchasing Power Parity Basis” shows the income (GDP) on a per person basis. For space, the chart has been condensed by removing lower profile countries, but the ranks are valid. Surprisingly, some of the hottest emerging-market countries—China, India, Turkey, Brazil, South Africa, and Mexico—rank very low on the income per person charts. So, why are these markets so exciting? One reason might be that companies selling cheaper, daily-use items, such as soap, shampoos, and low-end cosmetics, have found success entering developing, but promising, markets.

Purchasing Power Parity

To compare production and income across countries, we need to look at more than just GDP. Economists seek to adjust this number to reflect the different costs of living in specific countries. Purchasing power parity (PPP) is, in essence, an economic theory that adjusts the exchange rate between countries to ensure that a good is purchased for the same price in the same currency. For example, a basic cup of coffee should cost the same in London as in New York.

A nation’s GDP at purchasing power parity (PPP) exchange rates is the sum value of all goods and services produced in the country valued at prices prevailing in the United States. This is the measure most economists prefer when looking at per-capita welfare and when comparing living conditions or use of resources across countries. The measure is difficult to compute, as a US dollar value has to be assigned to all goods and services in the country regardless of whether these goods and services have a direct equivalent in the United States (for example, the value of an ox-cart or non-US military equipment); as a result, PPP estimates for some countries are based on a small and sometimes different set of goods and services. In addition, many countries do not formally participate in the World Bank’s PPP project to calculate these measures, so the resulting GDP estimates for these countries may lack precision. For many developing countries, PPP-based GDP measures are multiples of the official exchange rate (OER) measure. The differences between the OER- and PPP-denominated GDP values for most of the wealthy industrialized countries are generally much smaller.^[3]

In some countries, like Germany, the United Kingdom, or Japan, the cost of living is quite high and the per capita GDP (nominal) is higher than the GDP adjusted for purchasing power. Conversely, in countries like Mexico, Brazil, China, and India, the per capita GDP adjusted for purchasing power is higher than the nominal per capita GDP, implying that local consumers in each country can afford more with their incomes.

Human Development Index (HDI)

GDP and purchasing power provide indications of a country’s level of economic development by using an income-focused statistic. However, in recent years, economists and business analysts have focused on indicators that measure whether people’s needs are satisfied and whether the needs are equally met across the local population. One such indication is the human development index (HDI), which measures people’s satisfaction in three key areas—long and healthy life in terms of life expectancy; access to quality education equally; and a decent, livable standard of living in the form of income.

Since 1990, the United Nations Development Program (UNDP) has produced an annual report listing the HDI for countries. The HDI is a summary composite index that measures a country’s average achievements in three basic aspects of human development: health, knowledge, and a decent standard of living. Health is measured by life expectancy at birth; knowledge is measured by a combination of the adult literacy rate and the combined primary, secondary, and tertiary gross enrollment ratio; and standard of living by (income as measured by) GDP per capita (PPP US$).^[4]

While the HDI is not a complete indicator of a country’s level of development, it does help provide a more comprehensive picture than just looking at the GDP. The HDI, for example, does not reflect political participation or gender inequalities. The HDI and the other composite indices can only offer a broad proxy on some of the key the issues of human development, gender disparity, and human poverty.^[5] Table 4.1 “Human Development Index (HDI)—2010 Rankings” shows the rankings of the world’s countries for the HDI for 2010 rankings. Measures such as the HDI and its components allow global managers to more accurately gauge the local market.

In 1995, the UNDP introduced two new measures of human development that highlight the status of women in each society.

The first, gender-related development index (GDI), measures achievement in the same basic capabilities as the HDI does, but takes note of inequality in achievement between women and men. The methodology used imposes a penalty for inequality, such that the GDI falls when the achievement levels of both women and men in a country go down or when the disparity between their achievements increases. The greater the gender disparity in basic capabilities, the lower a country’s GDI compared with its HDI. The GDI is simply the HDI discounted, or adjusted downwards, for gender inequality.

The second measure, gender empowerment measure (GEM), is a measure of agency. It evaluates progress in advancing women’s standing in political and economic forums. It examines the extent to which women and men are able to actively participate in economic and political life and take part in decision making. While the GDI focuses on expansion of capabilities, the GEM is concerned with the use of those capabilities to take advantage of the opportunities of life.UNDP, “Measuring Inequality: Gender-related Development Index (GDI) and Gender Empowerment Measure (GEM),” Human Development Reports, accessed January 3, 2011, http://hdr.undp.org/en/statistics/indices/gdi_gem.

In 1997, UNDP added a further measure—the human poverty index (HPI).

If human development is about enlarging choices, poverty means that opportunities and choices most basic to human development are denied. Thus a person is not free to lead a long, healthy, and creative life and is denied access to a decent standard of living, freedom, dignity, self-respect and the respect of others. From a human development perspective, poverty means more than the lack of what is necessary for material well-being.

For policy-makers, the poverty of choices and opportunities is often more relevant than the poverty of income. The poverty of choices focuses on the causes of poverty and leads directly to strategies of empowerment and other actions to enhance opportunities for everyone. Recognizing the poverty of choices and opportunities implies that poverty must be addressed in all its dimensions, not income alone.UNDP, “The Human Poverty Index (HPI),” Human Development Reports, accessed January 3, 2011, http://hdr.undp.org/en/statistics/indices/hpi.

Rather than measure poverty by income, the HPI is a composite index that uses indicators of the most basic dimensions of deprivation: a short life (longevity), a lack of basic education (knowledge), and a lack of access to public and private resources (decent standard of living). There are two different HPIs—one for developing countries (HPI-1) and another for a group of select high-income OECD (Organization for Economic and Development) countries (HPI-2), which better reflects the socioeconomic differences between the two groups. HPI-2 also includes a fourth indicator that measures social exclusion as represented by the rate of long-term unemployment.^[7]
