Ten years ago we presented a modified version of Okun’s law for the biggest developed economies and reported its excellent predictive power. In this study, we revisit the original models using the estimates of real GDP per capita and unemployment rate between 2010 and 2019. The initial results...

The growth rate of real GDP per capita, GDPpc, is represented as a sum of two components – a monotonically decreasing economic trend and fluctuations related to population change. The economic trend is modelled by an inverse function of GDPpc with a constant numerator which varies for the...

Past and future evolution of inflation, (t), and unemployment, UE(t), in Japan is modeled. Both variables are represented as linear functions of the change rate of labor force level. These models provide an accurate description for disinflation in the 1990s and deflationary period in the 2000s....

This paper quantitatively demonstrates that modern estimates of income inequality based on the data reported by the IRS are not reliable. The principal problem of the estimates is highly volatile incomes of people in the low-end of income distribution. This volatility is likely related to...

Potential links between inflation, (t), and unemployment, UE(t), in Germany have been examined. There exists a consistent (conventional) Phillips curve despite some changes in monetary policy. This Phillips curve is characterized by a negative relation between inflation and unemployment with the...

A two-component model for the evolution of real GDP per capita in the USA is presented and tested. The first component of the GDP growth rate represents an economic trend and is inversely proportional to the attained level of real GDP per capita itself, with the nominator being constant through...

A linear and lagged relationship between inflation, unemployment and labor force change rate, ?(t)=A0UE(t-t0)+A1dLF(t-t1)/LF(t-t1)+A2 (where A0, A1, and A2 are empirical country-specific coefficients), was found for developed economies. The relationship obtained for France is characterized by...

Previously, a linear and lagged relationship between inflation and labor force change rate, π(t)= A1dLF(t-t1)/LF(t-t1)+A2 (where A1 and A2 are empirical country-specific coefficients), was found for developed economies. The relationship obtained for the USA is characterized by A1=4.0,...
