The increase of fuel extraction costs as well as of temperature will make it likely that in the medium-term future technological or political measures against global warming may be implemented. In assessments of a current climate policy the possibility of medium-term future developments like...

Several recent articles have analyzed climate policy giving explicit attention to the non-renewable character of carbon resources. In most of this literature the economy is treated as a single unit, which in the context of climate policy seems reasonable to interpret as the whole world. However,...

Well-intended policies aimed at reducing greenhouse gas emissions may have unintended undesirable consequences. Recently, a large literature has emerged showing under what conditions this so-called ‘Green Paradox’ may occur. We review this literature and identify the key mechanisms behind...

A sufficiently rapidly rising carbon tax may increase near-term emissions compared with the case of no carbon tax. Even so, such a carbon tax path may reduce total costs related to climate change, since the tax may reduce total carbon extraction. A government cannot commit to a specific carbon...

The Democratic Republic of Congo (DRC) is one of the poorest countries in the World. The construction sector will play an essential part to bring the country on the path of economic growth, and competition within the sector is crucial to achieve this goal. In this paper we analyze the effect of...

This paper sheds light on an empirical controversy about the effect of competition on price discrimination. We introduce individual demand uncertainty into Hotelling’s model of product differentiation and show that firms offer advance purchase discounts. Consumers choose between an early...

We analyse the effect of competition on quality in hospital markets with regulated prices, considering both the effect of (i) introducing competition (monopoly versus competition) and (ii) increasing competition through lower transportation costs (increased substitutability) or a higher number...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities), using a Hotelling framework, in the presence of sluggish demand. We take a differential-game approach, and derive the open-loop solution (providers choose the optimal...

This paper studies the impact of hospital competition on waiting times. We use a Salop-type model, with hospitals that differ in (geographical) location and, potentially, waiting time, and two types of patients; high-benefit patients who choose between neighbouring hospitals (competitive...

In this paper we show how an upstream firm can prevent destructive competition among downstream firms producing relatively close substitutes by implementing a price-dependent profit-sharing rule. The rule also ensures that the downstream firms undertake investments which benefit the industry in...
