In an increasingly global economy, GNI has been put forward as a potentially better metric for overall economic health than GDP.

Because certain countries have most of their income withdrawn abroad by foreign corporations and individuals, their GDP figure is much higher than the figure that represents their GNI. On the contrary, in the U.

In , U. Part of the reason for this is that population size and cost of living are not consistent around the world. For example, comparing the nominal GDP of China to the nominal GDP of Ireland would not provide much meaningful information about the realities of living in those countries because China has approximately times the population of Ireland. To help solve this problem, statisticians sometimes compare GDP per capita between countries. Even so, the measure is still imperfect.

Purchasing power parity PPP attempts to solve this problem by comparing how many goods and services an exchange-rate-adjusted unit of money can purchase in different countries—comparing the price of an item, or basket of items, in two countries after adjusting for the exchange rate between the two, in effect.

Real per-capita GDP, adjusted for purchasing power parity, is a heavily refined statistic to measure true income, which is an important element of well-being.

In nominal terms, the worker in Ireland is better off. Most nations release GDP data every month and quarter. The BEA releases are exhaustive and contain a wealth of detail, enabling economists and investors to obtain information and insights on various aspects of the economy. However, GDP data can have an impact on markets if the actual numbers differ considerably from expectations. Because GDP provides a direct indication of the health and growth of the economy, businesses can use GDP as a guide to their business strategy.

Government entities, such as the Fed in the U. If the growth rate is slowing, they might implement an expansionary monetary policy to try to boost the economy.

If the growth rate is robust, they might use monetary policy to slow things down to try to ward off inflation. Real GDP is the indicator that says the most about the health of the economy.

It is widely followed and discussed by economists, analysts, investors, and policy-makers. The advance release of the latest data will almost always move markets, although that impact can be limited, as noted above. Investors watch GDP since it provides a framework for decision-making. Comparing the GDP growth rates of different countries can play a part in asset allocation, aiding decisions about whether to invest in fast-growing economies abroad—and if so, which ones.

One interesting metric that investors can use to get some sense of the valuation of an equity market is the ratio of total market capitalization to GDP , expressed as a percentage.

Just as stocks in different sectors trade at widely divergent price-to-sales ratios, different nations trade at market-cap-to-GDP ratios that are literally all over the map. For example, according to the World Bank, the U. However, the utility of this ratio lies in comparing it to historical norms for a particular nation. As an example, the U. In retrospect, these represented zones of substantial overvaluation and undervaluation, respectively, for U.

The biggest downside of this data is its lack of timeliness; investors only get one update per quarter, and revisions can be large enough to significantly alter the percentage change in GDP. The concept of GDP was first proposed in in a report to the U.

At the time, the preeminent system of measurement was GNP. After the Bretton Woods conference in , GDP was widely adopted as the standard means for measuring national economies, although ironically, the U.

Beginning in the s, however, some economists and policy-makers began to question GDP. In other words, these critics drew attention to a distinction between economic progress and social progress.

There are, of course, drawbacks to using GDP as an indicator. In addition to the lack of timeliness, some criticisms of GDP as a measure are:. The World Bank hosts one of the most reliable web-based databases. It has one of the best and most comprehensive lists of countries for which it tracks GDP data.

The only drawback to using a Fed database is a lack of updating in GDP data and an absence of data for certain countries. Department of Commerce , issues its own analysis document with each GDP release, which is a great investor tool for analyzing figures and trends and reading highlights of the very lengthy full release. Countries with larger GDPs will have a greater amount of goods and services generated within them, and will generally have a higher standard of living.

Due to various limitations, however, many economists have argued that GDP should not be used as a proxy for overall economic success, much less the success of a society more generally. However, their ranking differs depending on how you measure GDP. Many economists, however, argue that it is more accurate to use purchasing power parity PPP GDP as a measure for national wealth.

Most people perceive a higher GDP to be a good thing because it is associated with greater economic opportunities and an improved standard of material well-being. It is possible, however, for a country to have a high GDP and still be an unattractive place to live, so it is important to also consider other measurements. For example, a country could have a high GDP and a low per-capita GDP , suggesting that significant wealth exists but is concentrated in the hands of very few people.

They liken the ability of GDP to give an overall picture of the state of the economy to that of a satellite in space that can survey the weather across an entire continent. GDP enables policy-makers and central banks to judge whether the economy is contracting or expanding, whether it needs a boost or restraint, and if a threat such as a recession or inflation looms on the horizon. Like any measure, GDP has its imperfections. In recent decades, governments have created various nuanced modifications in attempts to increase GDP accuracy and specificity.

Means of calculating GDP have also evolved continually since its conception to keep up with evolving measurements of industry activity and the generation and consumption of new, emerging forms of intangible assets.

Or equivalently, if you added up all the incomes earned by people in a country over the course of the year that would be GDP too. GDP is one way of measuring the size of a country's economy and judging whether that economy is growing over time.

So the citizens of a country with high GDP are likely to have high incomes and high standards of living and if GDP goes up a lot, people are likely to be earning and spending more and businesses are likely to be hiring and investing more. In other words people are likely to be feeling better off.

On the other hand if GDP growth is weak or perhaps even falling, companies are likely to be cutting jobs and people are likely to be earning and spending less, leaving them feeling worse off. Clearly GDP isn't all that matters in life. GDP doesn't measure a whole raft of things that improve our well-being, like spending time with our families or living in a clean and safe environment.

None the less, economic growth still matters because sustained rises in GDP have been shown, over the course of history to improve our health our wealth and our happiness. So suppose we have an economy that grows at around two and a half percent a year, that's roughly what its historic average has been over the past years.

Now two and a half percent might not sound like a lot but at that rate when my children reach my age, the economy will be nearly three times bigger than it is today. My children's incomes will be nearly three times larger than mine. Einstein said that not all that can be counted counts and he was right, but economic growth can be counted and because of its role in boosting living standards, it really does count.

When debt is used to fund economic expansion, current and future generations stand to reap the rewards. However, debt used to fuel consumption only presents advantages to the current generation. Because debt plays such an integral part of economic progress, it must be measured appropriately to convey the long-term impact it presents.

Unfortunately, evaluating the country's national debt in relation to its gross domestic product GDP is not the best approach. Here are three reasons why debt should not be assessed in this manner. The amount of the U. In theory, GDP represents the total market value of all final goods and services produced in a country in a given year. Based on this definition, one has to calculate the total amount of spending that takes place in the economy to estimate the country's GDP.

One approach is the use of the expenditure method , which defines GDP as the sum of all personal consumption of durable goods, nondurable goods and services; plus gross private investment, which includes fixed investments and inventories; plus government consumption and gross investment, which includes public-sector expenditures for services such as education and transportation, less transfer payments for services such as Social Security; plus net exports, which are simply the country's exports minus its imports.

Given this broad definition, one should realize the components that comprise GDP are hard to conceptualize in a manner that facilitates a meaningful evaluation of the appropriate national debt level. As a result, a debt-to-GDP ratio may not fully indicate the magnitude of national debt exposure. Therefore, an approach that is easier to interpret is simply to compare the interest expense paid on the national debt outstanding to the expenditures made for specific governmental services such as education, defense, and transportation.

When debt is compared in this manner, it becomes plausible for citizens to determine the relative extent of the burden placed by debt on the national budget. While the national debt can be precisely measured by the Treasury Department , economists have different views on how GDP should actually be measured. The first issue with measuring GDP is it ignores household production for services such as house cleaning and food preparation.

As a country develops and becomes more modern, people tend to outsource traditional household tasks to third parties. Given this change in lifestyle, comparing the GDP of a country today to its historical GDP is significantly flawed because the way people live today naturally increases GDP through the outsourcing of personal services. Moreover, GDP is typically used as a metric by economists to compare national debt levels among countries.

However, this process is also flawed because people in developed countries tend to outsource more of their domestic services than people in lesser-developed countries. As a result, any type of historical or cross-border comparison of debt in relation to GDP is completely misleading.

The second problem with GDP as a measurement tool is it ignores the negative side effects of various business externalities. For example, when companies pollute the environment, violate labor laws, or place employees in an unsafe working environment, nothing is subtracted from GDP to account for these activities. However, the capital, labor, and legal work associated with fixing these types of problems are captured in the calculation of GDP.

Technology not only increases GDP but also improves the quality of life for all people. Unfortunately, technological advances do not take place in a uniform manner each year. As a result, technology may skew GDP upward during certain years, which in turn may make the relative national debt level look acceptable when it is not.

Most ratios must be compared based on their change through time, but GDP fluctuations result in errors of calculation. The national debt has to be paid back with tax revenue, not GDP, although there is a correlation between the two. Using an approach that focuses on the national debt on a per capita basis gives a much better sense of where the country's debt level stands. Comparing the national debt level to GDP is akin to a person comparing the amount of their personal debt to the value of the goods or services they produce for their employer in a given year.

Clearly, this is not the way one would establish their own personal budget , nor is it the way the federal government should evaluate its fiscal operations. Given that the national debt has recently grown faster than the size of the American population, it is fair to wonder how this growing debt affects average individuals. While it may not be obvious, national debt levels directly affect people in at least five ways.

First, as the national debt per capita increases, the likelihood of the government defaulting on its debt service obligation increases, and therefore the Treasury Department will have to raise the yield on newly issued treasury securities to attract new investors. This reduces the amount of tax revenue available to spend on other governmental services because more tax revenue will have to be paid out as interest on the national debt.

Over time, this shift in expenditures will cause people to experience a lower standard of living , as borrowing for economic enhancement projects becomes more difficult. Second, as the rate offered on treasury securities increases, corporations operating in America will be viewed as riskier, necessitating an increase in the yield on newly issued bonds. This, in turn, will require corporations to raise the price of their products and services to meet the increased cost of their debt service obligation.

Over time, this will cause people to pay more for goods and services, resulting in inflation. Third, as the yield offered on treasury securities increases, the cost of borrowing money to purchase a home will increase because the cost of money in the mortgage lending market is directly tied to the short-term interest rates set by the Federal Reserve and the yield offered on treasury securities.
