Frequency of services and vehicle size are important policyinstruments of railway companies. Extending Mohring's basic'square root model' for frequencies, we arrive at more generalformulations for frequency, vehicle size and price underalternative regimes of welfare and profit optimisation. It...

The positive correlation between hourly wages and height, which results in higher labor supply of tall individuals, is well-documented in the literature. Accepting the utilitarian perspective and assuming that height does not affect utility implies that linking income taxes to height is welfare...

The standard model of optimal minimum wage policy in a perfectly competitive labor market suggests that a positive tax rate on minimum wage income is Pareto inefficient. However, most countries with minimum wage legislation exhibit a positive tax rate on minimum wage income. We solve this...

This paper provides a link between car following theory and the economic theoryof road congestion by means of a theory of speed choice. According to this theory speedchoice is based on a trade-off between the benefits (shorter travel time) and cost (higheraccident risk) of driving faster....
