Alcohol, addiction, congestion, migration & biodiversity

I have put online some recent papers of mine. Comments are welcome.

Thinking About Alcohol Policy. A reasonably liberal approach to the issue of regulating alcohol use.

The case against the case against skilled migration. An argument refuting suggestions Australia does not derive long-term gains from skilled migration. Awful double negatives I know.

Conserving biodiversity in the face of climate change. A survey of the economic issues that arise in attempting to adapt biodiversity strategies to the uncertain effects of climate change.

Being rational about rational addiction. A critical examination of the Becker and Murphy 'rational addiction' thesis (with Svetlana Danilkina).

Targeting urban congestion: equity and second-best issues. First-best arguments for comprehensive congestion pricing are often rejected because of equity implications and because pricing can only be partial. This paper revives a case for pricing with these constraints.
