Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We discuss phenomenological models of inelastic stock market response to aggregate money flows, including a model with a semi-permanent price impact. The conservation of money in financial transactions means that the aggregate cash investments go through rather than into the stock market, while not reaching the economics of stock issuers in any significant way but affecting stock prices via forces of supply and demand. Market microstructure embedded in a complex graph of money flow implies that the net flow of funds sets overall stock prices via price impact mechanics rather than economics. We argue that the overall secondary stock market capitalization is the result of limited supply of shares and growing demand by households, primarily via large institutions such as mutual and pension funds, and somewhat technical inelastic effects, rather than reflective of the underlying economic activity or enterprise value of the stock issuers. This observation makes long-term equity investment an economic paradox and raises further questions.
