We investigate how irreversibility in "dirty" and "clean" capital stocks affects optimal climate policy, from both theoretical and numerical perspectives. An increasing carbon tax will reduce investments in assets that pollute, and so reduce emissions in the short term: our "irreversibility effect". As such the "Green Paradox" has a converse if we...

We propose new techniques for understanding agents’ valuations. Our classification into “demand types”, incorporates existing definitions (substitutes, complements, “strong substitutes”, etc.) and permits new ones. Our Unimodularity Theorem generalises previous results about when competitive equilibrium exists for any set of agents whose valuations...

Duality techniques from convex geometry, extended by the recently-developed math-ematics of tropical geometry, provide a powerful lens to study demand. We propose a new framework of "demand types", for categorising and understanding demand; our classification both incorporates existing definitions (such as substitutes, complements, "strong substitu...

We construct the moduli spaces of stable maps, , via geometric invariant theory (GIT). This construction is only valid over , but a special case is a GIT presentation of the moduli space of stable curves of genus g with n marked points, ; this is valid over . In another paper by the first author, a small part of the argument is replaced, making the...
Article
Full-text available
In a previous paper, the author and Swinarski constructed the moduli spaces of stable maps, ℳ̄g, n(Pr, d) via geometric invariant theory (GIT). That paper required the base field to be the complex numbers, a restriction that this paper removes: here the coarse moduli spaces of stable maps are constructed via GIT over a more general base.

We show that, with indivisible goods, the existence of competitive equilibrium fundamentally depends on agents' substitution effects, not their income effects. Our Equilibrium Existence Duality allows us to transport results on the existence of competitive equilibrium from settings with transferable utility to settings with income effects. One cons...

This paper develops algorithms to solve strong-substitutes product-mix auctions. That is, it finds competitive equilibrium prices and quantities for agents who use this auction's bidding language to truthfully express their strong-substitutes preferences over an arbitrary number of goods, each of which is available in multiple discrete units. (Stro...
Article
We investigate (i) the impact of emission reduction policy on investment in polluting infrastructure, such as coal-fired power stations and (ii) optimal subsidies for “clean” alternatives with “learning” spillovers. We build a general theoretical model, and embed it in a fully calibrated integrated assessment model. Because emission reduction polic...
Article
An Equivalence Theorem between geometric structures and utility functions allows new methods for understanding preferences. Our classification of valuations into “Demand Types” incorporates existing definitions (substitutes, complements, “strong substitutes,” etc.) and permits new ones. Our Unimodularity Theorem generalizes previous results about w...

Hydrogen technologies and infrastructures might play a significant role in meeting ambitious climate and energy policy goals of the UK Government. Nonetheless, studies on hydrogen are either limited in scope in that they do not take into account the relationships with the wider energy system drivers and constraints or do not consider how a hydrogen...

In October 2010, a group of leading thinkers on environmental policy met at the Sustainable Consumption Institute at the University of Manchester for a conference in honour of Nobel Laureate Tom Schelling. This column presents a 10-point guideline for climate change policy co-authored by 26 attendees that focuses on designing policies that are cred...
