The link between tourism and growth is very important for some countries, especially small island countries like São Tomé and Príncipe. This paper investigates the empirical determinants of tourism outcomes (tourist arrivals and expenditures) and uses the findings to assess the performance of...

This paper proposes a functional coefficient quantile regression model with heterogeneous and time-varying regression coefficients and factor loadings. Estimation of the model coefficients is done in two stages. First, we estimate the unobserved common factors from a linear factor model with...

A new Stata command, xtsktest, is proposed to explore non-normalities in linear panel data models. The tests explore skewness and excess kurtosis allowing researchers to identify departures away from gaussianity in both error components of a standard panel regression, separately or jointly. The...
