Abstract
We consider the problem of variable selection in linear regression models. Bayesian model averaging has
become an important tool in empirical settings with large numbers of potential regressors and relatively limited numbers
of observations. We examine the effect of a variety of prior assumptions on the inference concerning model size, posterior
inclusion probabilities of regressors and on predictive performance. We illustrate these issues in the context of crosscountry
growth regressions using three datasets with 41 to 67 potential drivers of growth and 72 to 93 observations. Finally, we
recommend priors for use in this and related contexts.
