This paper considers the identification and estimation of hedonic models. We establish that in an additive version of the hedonic model, technology and preferences are generically identified up to affine transformations from data on demand and supply in a single hedonic market. For a very...

This paper presents the first investigation of the effects of optimal energy taxation in an urban spatial setting. Rather than exploring the effects of a carbon tax, our approach is to derive the supplements to existing taxes that are needed to support the social optimum. We then analyze the...

Climate change must deal with two market failures: global warming and learning by doing in renewable use. The first-best policy consists of an aggressive renewables subsidy in the near term and a gradually rising and falling carbon tax. Given that global carbon taxes remain elusive, policy...

The choice of an exchange rate peg often points to a trade-off between gaining credibility and losing flexibility. We show that the flexibility loss may be reduced if domestic and foreign shocks are coorelated and more volatile. Allowing for a plausible structural change after a peg, a...

This paper demonstrates that under conditions of imperfect (oligopolistic) competition, a transition from separate accounting (SA) to formula apportionment (FA) does not eliminate the problem of profit shifting via transfer pricing. In particular, if affiliates of a multinational firm face...

This paper provides the first analysis of the trade-off between convenient flight connections and airport congestion. A continuous spatial model illustrates this trade-off in a framework where a small gap between flight operating times raises congestion while also shortening a connecting...

This paper explores the effects of a European airline merger followed by a consolidation of two competing international alliances. The exercise has been inspired by the Air France-KLM merger, which is expected to spur consolidation of the Northwest-KLM and SkyTeam alliances into a single...

This paper analyzes the effect of transport subsidies on the spatial expansion of cities, asking whether subsidies are a source of undesirable urban sprawl. While the cost-reducing effect of transport subsidies is offset by a higher general tax burden (which reduces the demand for space), the...

We use perturbation methods to derive a rule for the optimal risk-adjusted social cost of carbon (SCC) that incorporates the effects of uncertainties associated with climate and the economy from a calibrated DSGE model. We allow for different aversions to risk and intertemporal fluctuations,...
