Economic growth - Wikipedia
Question: If an impact study identifies an increase in economic output of $ million, is that the same as a $ million increase in the gross. Find out the difference between GDP and GNP, and how each brings a different perspective to the meaning of economic success. It's one of the most important numbers in economics, but is GDP a good measure of But with the ONS now deciding to give "greater prominence" to broader . wasn't as bad as we first thought but have we felt the difference?.
Its failure to explain the determinants of these rates is one of its limitations. Although the rate of investment in the model is exogenous, under certain conditions the model implicitly predicts convergence in the rates of investment across countries. In a global economy with a global financial capital market, financial capital flows to the countries with the highest return on investment.
According to Harrod, the natural growth rate is the maximum rate of growth allowed by the increase of variables like population growth, technological improvement and growth in natural resources.
What Is the Relationship between GDP and Economic Growth?
In fact, the natural growth rate is the highest attainable growth rate which would bring about the fullest possible employment of the resources existing in the economy. Endogenous growth theory[ edit ] Main article: Endogenous growth theory Unsatisfied with the assumption of exogenous technological progress in the Solow—Swan model, economists worked to " endogenize " i. Unlike physical capitalhuman capital has increasing rates of return. Research done in this area has focused on what increases human capital e.
In doing so, they make old technologies or products obsolete. This can be seen as an annulment of previous technologies, which makes them obsolete, and "destroys the rents generated by previous innovations. Unified growth theory Unified growth theory was developed by Oded Galor and his co-authors to address the inability of endogenous growth theory to explain key empirical regularities in the growth processes of individual economies and the world economy as a whole.
The theory suggests that during most of human existence, technological progress was offset by population growth, and living standards were near subsistence across time and space.
However, the reinforcing interaction between the rate of technological progress and the size and composition of the population has gradually increased the pace of technological progress, enhancing the importance of education in the ability of individuals to adapt to the changing technological environment.
The rise in the allocation of resources towards education triggered a fertility decline enabling economies to allocate a larger share of the fruits of technological progress to a steady increase in income per capita, rather than towards the growth of population, paving the way for the emergence of sustained economic growth.
The theory further suggests that variations in biogeographical characteristics, as well as cultural and institutional characteristics, have generated a differential pace of transition from stagnation to growth across countries and consequently divergence in their income per capita over the past two centuries. Economic inequality and Effects of economic inequality The dominating views about the role of inequality in the growth process have radically shifted in the past century.
Specifically, they argued that since the aggregate saving increases with inequality, due to higher property to save among the wealthy, inequality increases capital accumulation and therefore economic growth. The modern viewpoint that emerged in the late s and have established in contrast that income distribution has a significant impact on the growth process. This modern perspective, originated by Galor and Zeira   has highlighted the role of heterogeneity in the determination of macroeconomic activity, and has demonstrated that income distribution is an important determinants of the growth process and the evolution of income per capita.
In particular, Galor and Zeira have argued that since credit markets are imperfect, inequality has an enduring impact on human capital formation, the level of income per capita, and the growth process.
Later theories have reinforced the view that inequality has an adverse effect on the growth process.
Specifically, Alesina and Rodrik and Persson and Tabellini advanced a political economy mechanism and argue that inequality has a negative impact on economic development since it creates a pressure for distortionary redistributive policies that have an adverse effect on investment and economic growth. In contrast, his examination of the political economy channel found no support for the political economy mechanism. Specifically, inequality in the distribution of land ownership provides the landed elite to block the development of the industrial sector, but depriving workers from education and limiting their mobility to the industrial sector.
This unified theory of inequality and growth suggests that the replacement of physical capital accumulation by human capital accumulation as the main engine of economic growth reversed the impact of inequality on the growth process. In the early stages of industrialization, when physical capital accumulation was the dominating source of economic growth, inequality enhanced the development process by directing resources toward individuals whose propensity to save is higher.

However, in later stages of development, as human capital become the main engine of economic growth, more equal distribution of income, in the presence of credit constraints, stimulated investment in human capital and economic growth. Other factors affecting growth[ edit ] Political institutions, property rights, and rule of law[ edit ] See also: These included new laws favorable to the establishment of business, including contract law and laws providing for the protection of private property, and the abolishment of anti-usury laws.
Enforcement of contractual rights is necessary for economic development because it determines the rate and direction of investments. When the rule of law is absent or weak, the enforcement of property rights depends on threats of violence, which causes bias against new firms because they can not demonstrate reliability to their customers. Thanks to the underlying homogeneity of its land and people, England was able to achieve a unified legal and fiscal system since the Middle Ages that enabled it to substantially increase the taxes it raised after Many of these intermediate level institutions relied on informal private-order arrangements that combined with public-order institutions associated with states, to lay the foundations of modern rule of law states.
In many urban areas the poor "invade" private or government land to build their houses, so they do not hold title to these properties. Much unregistered property is held in informal form through various property associations and other arrangements. Reasons for extra-legal ownership include excessive bureaucratic red tape in buying property and building. In some countries it can take over steps and up to 14 years to build on government land.
Other causes of extra-legal property are failures to notarize transaction documents or having documents notarized but failing to have them recorded with the official agency. Unregistered businesses and lack of accepted accounting methods are other factors that limit potential capital. Specifically, "democracy increases future GDP by encouraging investment, increasing schooling, inducing economic reforms, improving public goods provision, and reducing social unrest.
Europeans adopted very different colonization policies in different colonies, with different associated institutions. In places where these colonizers faced high mortality rates e. In these 'neo-Europes' better institutions in turn produced better development outcomes. Thus, although other economists focus on the identity or type of legal system of the colonizers to explain institutions, these authors look at the environmental conditions in the colonies to explain institutions.
For instance, former colonies have inherited corrupt governments and geopolitical boundaries set by the colonizers that are not properly placed regarding the geographical locations of different ethnic groups, creating internal disputes and conflicts that hinder development.

In another example, societies that emerged in colonies without solid native populations established better property rights and incentives for long-term investment than those where native populations were large.
However, surprisingly few research empirically examine and quantify entrepreneurship's impact on growth. This is due to endogeneity - forces that drive economic growth also drive entrepreneurship. In other words, the empirical analysis of the impact of entrepreneurship on growth is difficult because of the joint determination of entrepreneurship and economic growth.
A few papers use quasi-experimental designs, and have found that entrepreneurship and the density of small businesses indeed have a causal impact on regional growth.Difference between GDP and GNP
Capital is subject to diminishing returns because of the amount that can be effectively invested and because of the growing burden of depreciation. In the development of economic theory the distribution of income was considered to be between labor and the owners of land and capital. New products create demand, which is necessary to offset the decline in employment that occurs through labor-saving technology and to a lesser extent employment declines due to savings in energy and materials.
Also, the creation of new services has been more important than invention of new goods.
Rostow's stages of growth Economic growth in the U. Revisions Another perennial issue around output statistics is that they are subject to near constant revision.
Earlier this year, changes in the way the ONS calculates economic output revealed that the British economy exited recession nine months earlier than we first thought.
Although significant for economic historians and very good news for the Chancellor, it is questionable whether the revisions had any discernible impact on how individuals felt in the aftermath of the crisis. It is facts such as these which have now prompted the ONS to take look at a broader set of indicators that can help up understand what the recovery has really meant for most people.
So what can we use instead? The ONS has yet to reveal which set of metrics they will be putting out alongside GDP figures to measure our economic well-being, but they are likely to include a number of existing measures that are already part of our national accounts. Income The yellow line below represents the total national disposable income held by Brits and adjusted for inflation. The chart shows that for the most part, disposable income levels have tracked GDP per capita quite closely.
But unlike the black line above, which has been relatively flat sincethe population's net disposable income has been falling steadily since It's also possible to take a closer look at how individual incomes have fared by examining disposable cash at the household level.
According to the ONS, this is a measure which "seems directly relevant to assessment of households' economic well-being. They have however gone into steady decline sincefailing to pick up even as the recovery has generated momentum. The red line above is a measure of the average, or median, household income. This provides some indication of how income and resources are distributed across the population.
For example, although overall income levels may be unchanged, this could still mask a shift in distribution with the richest households taking a bigger slice than those at the poorer end of the scale. The median income line tracks disposable income quite closely, suggesing that there have been no major distributional changes in income since the recession. Wealth Along with income, wealth is also a useful gauge of our material well-being.
The ONS already calculates household wealth based on the value of our physical and financial assets. The green bar above shows how rising wealth was driven by a property price boom from Since the onset of the recession however, net property wealth fell, approaching its pre-crisis peak in
