  • Tourism activity affects house price dynamics? Evidence for countries dependent on tourism
    Publication . 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-run and in the long-run. The Granger causality tests show that tourism activity Granger-causes house prices in the eight countries analysed. These results have important practical and political implications. There is a delicate environment and social equilibrium in tourist destinations that it is necessary to ensure. If it is true that tourism has positive effects on the economy through job creation and economic growth it is also important to internalize the negative externalities caused by tourism, through the adoption of appropriate economic instruments and policies.
  • The collapse of Silicon Valley Bank and Credit Suisse and their impact on other U.S. Banks
    Publication . Martins, António Miguel; Martins, António
    ABSTRACT This paper examines how US banking industry responded to the collapse of Silicon Valley Bank and Credit Suisse. The analysis of abnormal returns surrounding the announcement of the collapse of Silicon Valley Bank and Credit Suisse reveals a negative and statistically significant impact on the largest listed US banks. Banks’ market value loss is explained by information asymmetries and uncertainty returns, systemic contagion, and panic. These reactions are reinforced or mitigated by bank-specific characteristics such as size, liquidity, profitability, risk aversion, operational efficiency, institutional ownership, internationalization, dependence on uninsured deposits and ratio of off balance sheet items.
