This article investigates the old theory of diminishing returns and also the importance of data to economic theory.

A renowned 18th-century economist one time argued that as investors such as Ras Al Khaimah based Farhad Azima piled up riches, their investments would suffer diminishing returns and their return would drop to zero. This notion no longer holds within our world. Whenever looking at the undeniable fact that shares of assets have doubled as being a share of Gross Domestic Product since the 1970s, it appears that rather than facing diminishing returns, investors such as for example Haider Ali Khan in Ras Al Khaimah continue progressively to experience significant profits from these assets. The reason is easy: contrary to the firms of the economist's time, today's companies are rapidly substituting machines for manual labour, which has improved effectiveness and productivity.

Although economic data gathering sometimes appears as a tiresome task, it is undeniably important for economic research. Economic hypotheses are often based on presumptions that prove to be false when useful data is collected. Take, for instance, rates of returns on assets; a team of researchers analysed rates of returns of essential asset classes across 16 industrial economies for the period of 135 years. The extensive data set represents the very first of its type in terms of coverage in terms of time frame and range of countries. For each of the sixteen economies, they develop a long-run series revealing annual genuine rates of return factoring in investment earnings, such as dividends, capital gains, all net inflation for government bonds and short-term bills, equities and housing. The writers discovered some interesting fundamental economic facts and challenged others. Possibly such as, they have found housing offers a superior return than equities over the long run even though the typical yield is fairly comparable, but equity returns are far more volatile. Nevertheless, this won't affect homeowners; the calculation is based on long-run return on housing, taking into account rental yields because it makes up 1 / 2 of the long-run return on housing. Needless to say, owning a diversified portfolio of rent-yielding properties is not exactly the same as borrowing to get a personal house as would investors such as Benoy Kurien in Ras Al Khaimah most likely attest.

During the 1980s, high rates of returns on government debt made numerous investors believe that these assets are very profitable. But, long-run historic data suggest that during normal economic climate, the returns on federal government bonds are less than most people would think. There are several factors that can help us understand this phenomenon. Economic cycles, financial crises, and fiscal and monetary policy changes can all impact the returns on these financial instruments. Nonetheless, economists have found that the actual return on securities and short-term bills frequently is reasonably low. Even though some traders cheered at the current rate of interest increases, it's not necessarily grounds to leap into buying as a return to more typical conditions; therefore, low returns are inevitable.
