AbstractThis paper provides estimates of tobacco price elasticity explicitly distinguishing between two price effects: the direct effect, reflecting individual reaction to a price change, and the indirect effect, whereby price influences the individual by changing community smoking behaviour. Canada's Aboriginal communities are small and secluded, allowing for plausible identification of reference groups on a relatively large scale. Estimates suggest a 10% increase in price decreases daily smoking by 0.91 percentage points (2.11%), occasional smoking by 1.24 percentage points (8.27%) and average smoking intensity by 0.15 cigarettes per day (2.9%). It is found that the indirect effect almost doubles the response to a change in tobacco prices over the direct effect alone.

Abstract Biases in meeting opportunities have been recently shown to play a key role for the emergence of homophily in social networks (see Currarini et al., 2009). The aim of this paper is to provide a simple microfoundation of these biases in a model where the size and type-composition of the meeting pools are shaped by agents׳ socialization decisions. In particular, agents either inbreed (direct search only to similar types) or outbreed (direct search to population at large). When outbreeding is costly, this is shown to induce stark equilibrium behavior of a threshold type: agents "inbreed" (i.e. mostly meet their own type) if, and only if, their group is above certain size. We show that this threshold equilibrium generates patterns of in-group and cross-group ties that are consistent with empirical evidence of homophily in two paradigmatic instances: high school friendships and interethnic marriages. ; Biases in meeting opportunities have been recently shown to play a key role for the emergence of homophily in social networks (see Currarini et al., 2009).

Abstract.  We investigate the impact of Canada's means‐tested and universal public pension programs on the mortality rates of age groups eligible for pension benefits for the period 1921–1966. We find that only the universal program significantly reduced pension eligible age group mortality rates. The implied social value of the mortality risk reduction from this program is one‐tenth of the value per statistical life associated with contemporary government policy, meaning that Canadians did not need to place a high value on the life of a senior to justify the higher cost of the universal program.

AbstractWe estimate the importance of local labour structure in the spread of COVID‐19 during the first year of the pandemic. We build a unique dataset across 6791 English neighbourhoods that distinguishes between people living (residents) and people working (workers) in a neighbourhood, and differentiate between jobs that can be done from home (homeworkers), jobs that likely continued on‐site (keyworkers), and non‐essential on‐site jobs. We find that a 10 percentage points increase in keyworker jobs among residents is associated with 3.15 more cases per 1000 (4.8% relative to the mean), while a 10 percentage points increase in homeworker jobs among residents is associated with a decrease of 7.74 cases per 1000 (11.8% relative to the mean). Results for the composition of workers show the same sign, but smaller magnitudes. A dynamic analysis of the monthly incidence of reported cases shows that these relationships are particularly strong during lockdown periods. These results are heterogeneous across neighbourhoods, with larger positive effect of keyworkers, and lower protective effect of homeworkers, in higher deprivation areas. We explore the role of occupation skill intensity in driving these neighbourhood differences. These findings highlight important asymmetries in the distributional impact of the policy response to COVID‐19.

We investigated the 5.3 percentage point increase in the prevalence of food insecurity in Canada between the National Population Health Survey of 1998–99 and the Canadian Community Health Survey of 2000–01. We found that the increase in food insecurity occurred disproportionately in households in the western provinces, particularly Alberta, and among homeowners rather than renters. Inter-provincial variation in heating cost inflation explained as much as 61 percent of the inter-provincial variation in food insecurity increases between 1998 and 2001.
