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

Throughout the 1980s, high rates of returns on government bonds made numerous investors genuinely believe that these assets are very profitable. But, long-term historical data indicate that during normal economic conditions, the returns on federal government debt are lower 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. Nevertheless, economists have found that the real return on securities and short-term bills frequently is reasonably low. Even though some traders cheered at the present rate of interest increases, it's not normally grounds to leap into buying as a return to more typical conditions; therefore, low returns are inevitable.

A famous eighteenth-century economist one time argued that as investors such as Ras Al Khaimah based Farhad Azima accumulated riches, their assets would suffer diminishing returns and their return would drop to zero. This notion no longer holds in our global economy. Whenever taking a look at the undeniable fact that stocks of assets have doubled as a share of Gross Domestic Product since the seventies, it appears that as opposed to facing diminishing returns, investors such as for instance Haider Ali Khan in Ras Al Khaimah continue steadily to reap significant earnings from these assets. The reason is easy: unlike the firms of the economist's time, today's companies are increasingly replacing devices for human labour, which has boosted effectiveness and output.

Although data gathering is seen as being a tiresome task, it's undeniably crucial for economic research. Economic theories tend to be predicated on assumptions that prove to be false as soon as trusted data is collected. Take, for example, rates of returns on assets; a small grouping of researchers analysed rates of returns of essential asset classes across 16 industrial economies for the period of 135 years. The extensive data set provides the very first of its kind in terms of extent with regards to time period and range of economies examined. For each of the sixteen economies, they develop a long-term series presenting yearly real rates of return factoring in investment earnings, such as for instance dividends, capital gains, all net inflation for government bonds and short-term bills, equities and housing. The writers uncovered some new fundamental economic facts and questioned others. Maybe especially, they have found housing provides a superior return than equities in the long run although the average yield is fairly similar, but equity returns are far more volatile. But, this won't apply to home owners; the calculation is based on long-run return on housing, taking into consideration rental yields since it makes up about half of the long-run return on housing. Needless to say, having a diversified portfolio of rent-yielding properties is not the exact same as borrowing to purchase a personal home as would investors such as Benoy Kurien in Ras Al Khaimah likely attest.
