A note on Heckman-type corrections in models for zero expenditures

In Heien and Wessells (1990), a two-step estimation procedure, that makes use of Heckman-type corrections, is proposed to estimate consumption on household budget surveys. It is shown that this approach, which draws from switching regressions models, leads to inconsistent estimates.

Voting on prices vs. voting on quantities in a World Climate Assembly

This paper posits the conceptually useful allegory of a futuristic “World Climate Assembly” that votes on global carbon emissions via the basic principle of majority rule. Two variants are considered. One is to vote on a universal price (or tax) that is internationally harmonized, but the proceeds from which are domestically retained. The other is to vote on the overall quantity of total worldwide emissions, which are then distributed for free (via a pre-decided fractional subdivision formula) as individual allowance permits that are subsequently marketed in an international cap-and-trade system. The model of the paper suggests that the majority-voted price is likely to be less distortionary and easier to enact than the majority-voted total quantity of permits. Some possible implications for climate-change negotiations are noted.

Planning Reform and Housing Costs: Why The Coalition Failed and What it Means

Housing costs in the UK have exploded in recent decades. Contrary to what is often claimed, this has nothing to do with population density, demographics or a lack of public housing. A review of the empirical literature shows that the key determinant of housing costs is the severity of planning restrictions. Faced with a well‐organised NIMBY opposition, the coalition failed in its attempt to make the planning system more development‐friendly. This is not surprising, because the current system provides incentives which make NIMBYism a rational option. The coalition ought to address these incentives rather than trying to sidestep them.
