This paper extends the growth cycle model à la Goodwin (1967) by introducing the risk-averse behaviour af the agents.

We estimate output growth rate spectra for 58 countries. The spectra exhibit diverse shapes. To study the sources of this diversity, we estimate the short-run, business cycle, and long-run frequency components of the sampled series. For most OECD countries the bulk of the spectral mass is in the...

A simple dynamic IS-LM model with "balanced budget" and money financing deficit can show, in the presence of realistic tax collection lags, regular and chaotic cycles depending on the "mix" of fiscal policies. We argue that also rigid and transparent expenditure limits which an increasing number...

A new technique to estimate simultaneously the potential output and Phillips curve is demonstrated. Here we define the potential output as the non-accelerating-inflation level of output (NLO). The NLO is not a mere trend of the actual output, but rather is a critical level of output with the...

Labour productivity distribution (dispersion) is studied within the framework of statistical physics and the result is compared with the outcome of the empirical analysis. Superstatistics is presented as a natural theoretical framework for the productivity distribution. The demand index ê is...

Labour productivity distribution (dispersion) is studied both theoretically and empirically. Superstatistics is presented as a natural theoretical framework for productivity. The demand index ê is proposed within this framework as a new business index. Japanese productivity data covering...
