The article ‘Growth in a Time of Debt’ published in papers was erroneous. While conducting an economic review, Reinhart and Rogoff linked debts to slow growth (Rogoff & Reinhart, 2013). The critics Thomas Herndon Michael Ash Robert Pollinn identified a spreadsheet mistake in calculation. Furthermore, the critics claimed that the writers were biased since they omitted vital data and improperly weighted summary statistics. The writers Reinhart and Rogoff, however, tried to correct the allegations of biased records but acknowledged the calculation errors. However, the critics refused to publish that both median and average estimates of growth were included in the statistics. Instead, they insisted that these writers based their research on one outlier estimate of growth. The writers establish that their paper focused more on median estimates to eliminate the error due to outliers. These estimates are allegedly similar to those of the University of Massachusetts researchers. The critics, however, published a review of the same article giving estimates with minor discrepancies to the information in the original article. However, the bank of international settlements and the international monetary fund drew an analysis that concluded that the correlation between growth and debt was negative. Reinhart and Rogoff address these allegations in their article Op-Ed and claim that their critics politicized the matter. Their critics ironically seemed to focus more on minor errors of calculations and omissions but again went ahead to publish a similar article with minor changes.
