Cró, Susana; Martins, António Miguel; Martins, António

This study analyses the impact of tourism in house prices in eight tourism dependent countries in terms of exports for the period from 2000 to 2018. We employ a Vector-Error Correction Model (VECM) for the empirical estimation given that house prices, tourism activity and other determinants are cointegrated. The results indicate that tourism has a significant positive impact on house prices both in the short-ru...

We chose a sample of countries with different levels of fulfilment of human rights by the fact that previous studies show that human rights violation has far more severe imp...
