We present the Phillips curve in Australia in the frequency domain and document an evolving pattern in its slope at low frequencies under different monetary policy regimes and labor market regulations. The RBA adopted monetary targeting in 1976 and inflation targeting in 1993. There were...

Railway networks are characterised by variations in demand on different links. Optimal strategies therefore call for a differentiated treatment of fares, frequencies and vehicle sizes in various links. However, for several reasons, railway operators may apply uniform levels for these decision...

We develop a duopoly model to analyze the impact of air transport and high-speed rail (HSR) competition on the environment and social welfare. We show that the introduction of HSR may have a net negative effect on the environment, since it may result in additional demand, i.e., there is a...
