Evaluating the empirical validity of Modern Monetary Theory, this study implements panel cointegration analysis on annual panel data (2000-2022) of OECD countries. Specifically, the sample countries are divided into groups based on the presence of their own sovereign currencies, and for each group, the long-run equilibrium relation (cointegration) between the ratio of public debt or fiscal deficit and government bond rates is tested and estimated. Main findings are as follows: applying the pooled mean-group estimation for panel cointegration, it is found that both the ratios of public debt and fiscal deficit have significantly positive long-run correlation with government bond rates in countries without sovereign currency such as the Euro-zone or fixed exchange rate regime countries. However, in countries with sovereign currency such as non-Euro-zone or floating exchange rate regime countries, the long-run correlation is either negative or not statistically significant. Particularly, in countries without sovereign currency, the ratio of public debt has significantly positive correlation with the real government bond rates in the short run as well as the long run. These results are consistent with the prediction of Modern Monetary Theory, thus providing a supporting evidence for the empirical validity of the theory.

The purpose of this study is to firstly estimate the inflation rate of North Korea using relative purchasing power parity. Most of the existing studies use North Korean rice prices as proxy to explain changes in North Korean prices. In this study, North Korea's price was estimated by applying purchasing power parity, which was used to estimate the price of socialist countries in the past, to North Korea. Second, it analyzes the impact of North Korea's price inflation after the institutional change of currency reform. We looked at the movements of North Korean prices after the institutional change of currency reform and compared it with the post-monetary reform of other socialist countries. We examine the impact of currency reform on North Korea, focusing on the price. As a result, after the currency reform in 2009, North Korea experienced hyperinflation. The North Korean inflation rate in the model was 3,010.0% in 2010, 195.0% in 2011, 68.0% in 2012 and 48.3% in 2013. After the currency reform of North Korea, the inflation rate is much higher than the socialist countries such as China and Vietnam who had experienced currency reform before. North Korea's monetary reforms are considered to have failed because of the side effects of hyperinflation.

This paper examines works of F. Hayek and M. Friedman on monetary and financial policies. This paper highlights their differences, and asks what yielded them. It also shows there exists a gap between young Hayek and old Hayek, which cannot be explained in terms of his view on monetary theories. It further shows that Friedman's argument for '100% reserve bank' was not based on his monetary theories. Differences between Hayek and Friedman despite their common political belief, Hayek's transition, gaps between theories and policy views found in Hayek and Friedman-this paper argues that these facts can be best explained by Kuhn's paradigm theory. This paper concludes that truthfulness of a thesis on the public sector's role in the monetary system is subject to relativism.
