By the late 19th century both prices and weekly work hours fell because less labor, materials, and energy were required to produce and transport goods. However, real wages rose, allowing workers to improve their diet, buy consumer goods and afford better housing. New goods and services included television, air conditioning and commercial aviation aftercreating enough new demand to stabilize the work week. Productivity in the United States grew at an increasing rate throughout the 19th century and was most rapid in the early to middle decades of the 20th century.
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. Demographic factors may influence growth by changing the employment to population ratio and the labor force participation rate. Women with fewer children and better access to market employment tend to join the labor force in higher percentages.
There is a reduced demand for child labor and children spend more years in school. The increase in the percentage of women in the labor force in the U.

Spending wave Other factors affecting growth[ edit ] Human capital[ edit ] Many theoretical and empirical analyses of economic growth attribute a major role to a country's level of human capitaldefined as the skills of the population or the work force. Human capital has been included in both neoclassical and endogenous growth models. The most commonly-used measure of human capital is the level average years of school attainment in a country, building upon the data development of Robert Barro and Jong-Wha Lee.
One problem with the schooling attainment measure is that the amount of human capital acquired in a year of schooling is not the same at all levels of schooling and is not the same in all countries.
This measure also presumes that human capital is only developed in formal schooling, contrary to the extensive evidence that families, neighborhoods, peers, and health also contribute to the development of human capital.
He shows that economic growth is not correlated with average scores in more educated countries. They show that the level of students' cognitive skills can explain the slow growth in Latin America and the rapid growth in East Asia. 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. Investment takes place when we purchase new capital equipment or other assets that make for future productivity. Investment does not mean buying stocks or bonds. Here are some important facts: However, for the larger economy, this is not true. Investment funds come either from our own saving or from someone else's saving.
We will later draw supply and demand curves and show how saving and investment are equated. The rest of the deposits constitute savings, or cumulative saving. Warning required by the Economist-General: Put simply, an interest rate is the price of a loan, expressed as a percentage of the amount loaned each year. The interest rate is the price the bank pays you. In short, interest is either the reward you get for saving or the premium you pay for having funds now rather than later.
As we shall see, the concept of interest is a crucial economics concept. Why do People Invest?
People invest to make money.
