What is the role of transport improvements in globalization? We argue that the nineteenth century is the ideal testing ground: maritime freight rates fell on average by 50% while global trade increased 400% from 1870 to 1913. We estimate the first indices of bilateral freight rates and directly...

Using data collected by the International Institute of Agriculture, we document the disintegration of international commodity markets between 1913 and 1938. There was dramatic disintegration during World War I, gradual reintegration during the 1920s, and then a very substantial disintegration...

What has driven trade booms and trade busts in the past and present? We derive a micro-founded measure of trade frictions from leading trade theories and use it to gauge the importance of bilateral trade costs in determining international trade flows. We construct a new balanced sample of...

In this paper, I estimate the poverty rate as the proportion of individuals who have consumption - rather than income - lower than an absolute poverty line. The absolute poverty line used is based on the expenditure necessary to achieve a minimum level of material well-being. It does not change...

We use quantile regression methods on 2001 Census of Canada data to assess disparity at four points in the conditional distribution of earnings of native-born ethnic minorities (the 20th, 50th, 80th and 90th percentiles) as well as at the mean. In doing so, we examine and assess the degree to...

We assess the evolution of consumption inequality in Canada over the years 1997 to 2009. We correct the imputation of shelter consumption for owner-occupiers to allow for unobserved differences in housing quality correlated with selection into rental tenure, and we account for measurement error...

The share of household resources devoted to children is hard to identify because consumption is measured at the household level and goods can be shared. Using semiparametric restrictions on individual preferences within a collective model, we identify how total household resources are divided up...

We present a new class of social cost-of-living indices and a nonparametric framework for estimating these and other social cost-of-living indices. Common social cost-of-living indices can be understood as aggregator functions of approximations of individual cost-of-living indices. The Consumer...

We invent Implicit Marshallian Demands, a new type of demand function that combines desirable features of Hicksian and Marshallian demand functions. We propose and estimate the Exact Affine Stone Index (EASI) Implicit Marshallian Demand system. Like the Almost Ideal Demand (AID) system, EASI...

We invent Implicit Marshallian demands, which combine desirable features of Hicksian and Marshallian demands. We propose and estimate the Exact Affine Stone Index (EASI) implicit Marshallian demand system. Like the Almost Ideal Demand (AID) system, EASI budget shares are linear in parameters...
