This paper examines growth in output per person in 17 OECD countries from the late nineteenth century to 1989 considering the possibility of several breaks in trend. In all cases the unit root hypothesis is rejected in favour of a segmented trend stationary alternative. 1951-73 is shown to be an...

Skepticism toward traditional identifying assumptions based on exclusion restrictions has led to a surge in the use of structural VAR models in which structural shocks are identified by restricting the sign of the responses of selected macroeconomic aggregates to these shocks. Researchers...

A common view in the literature is that the effect of energy price shocks on macroeconomic aggregates is asymmetric in energy price increases and decreases. We show that widely used asymmetric vector autoregressive models of the transmission of energy price shocks are misspecified, resulting in...

Models that treat innovations to the price of energy as predetermined with respect to U.S. macroeconomic aggregates are widely used in the literature. For example, it is common to order energy prices first in recursively identified VAR models of the transmission of energy price shocks. Since...

There is a long tradition of using oil prices to forecast U.S. real GDP. It has been suggested that the predictive relationship between the price of oil and one-quarter ahead U.S. real GDP is nonlinear in that (1) oil price increases matter only to the extent that they exceed the maximum oil...

The run-up in oil prices since 2004 coincided with growing investment in commodity markets and increased price comovement among different commodities. We assess whether speculation in the oil market played a role in driving this salient empirical pattern. We identify oil shocks from a large...

This paper presents a structural dynamic factor model of a small commodity-exporting economy using Canada as a representative case study. Combining large panel data sets of the global and Canadian economies, we first identify those demand and supply shocks that explain most of the volatility in...

A household panel data set is used to investigate the effects of economic growth on firewood collection in Nepal between 1995 and 2010. Results from preceding cross-sectional analyses are found to be robust: (a) rising consumptions for all but the top decile were associated with increased...

This paper examines alternative methods which have been used to measure aggregate energy consumption over time. It is found that many of the measures which have been widely used in empirical studies are not appropriate for economic analysis. The concept of 'useful energy', popular in engineering...

We consider a linguistically diversified society that has to select a set of official languages. We examine the notion of language disenfranchisement that is created when one or more languages fail to be included in the list of the official ones, implying that some individuals are denied full...
