This article investigates the old concept of diminishing returns as well as the need for data to economic theory.

A distinguished eighteenth-century economist one time argued that as investors such as Ras Al Khaimah based Farhad Azima accumulated wealth, their investments would suffer diminishing returns and their return would drop to zero. This idea no longer holds within our global economy. Whenever looking at the fact that stocks of assets have doubled being a share of Gross Domestic Product since the 1970s, it would appear that in contrast to dealing with diminishing returns, investors such as for example Haider Ali Khan in Ras Al Khaimah continue steadily to reap significant profits from these investments. The explanation is simple: unlike the companies of his day, today's companies are increasingly substituting machines for human labour, which has enhanced efficiency and productivity.

During the 1980s, high rates of returns on government debt made many investors believe these assets are extremely lucrative. Nevertheless, long-term historical data indicate that during normal economic conditions, the returns on federal government debt are less than people would think. There are numerous facets which will help us understand reasons behind this trend. Economic cycles, monetary crises, and financial and monetary policy modifications can all affect the returns on these financial instruments. Nonetheless, economists are finding that the actual return on bonds and short-term bills often is relatively low. Although some traders cheered at the present rate of interest increases, it's not normally reasons to leap into buying because a reversal to more typical conditions; therefore, low returns are inevitable.

Although data gathering is seen as being a tiresome task, it really is undeniably important for economic research. Economic theories are often predicated on presumptions that prove to be false as soon as trusted data is collected. Take, for example, rates of returns on assets; a small grouping of scientists analysed rates of returns of important asset classes in 16 advanced economies for the period of 135 years. The extensive data set provides the very first of its kind in terms of extent in terms of time frame and number of countries. For all of the 16 economies, they develop a long-term series showing yearly real rates of return factoring in investment earnings, such as dividends, money gains, all net inflation for government bonds and short-term bills, equities and housing. The authors discovered some new fundamental economic facts and questioned others. Maybe most notably, they've concluded that housing offers a better return than equities in the long run although the average yield is fairly similar, but equity returns are even more volatile. Nevertheless, this does not apply to property owners; the calculation is dependant on long-run return on housing, taking into consideration rental yields since it accounts for 1 / 2 of the long-run return on housing. Needless to say, owning a diversified portfolio of rent-yielding properties isn't the same as borrowing to get a personal home as would investors such as Benoy Kurien in Ras Al Khaimah most likely confirm.
