Abstract

The global financial crisis and its high economic and social costs have revived academic and policy interest in “early warning indicators” of crises. This paper aims to investigate the performance of vulnerability indicators as advance warning indicators of past severe GDP per capita recessions in Turkey. It draws on the recently established database of vulnerability indicators (Röhn et al., 2015) and employs the signalling approach as in Hermansen and Röhn (2015) complemented by visual inspections to detect vulnerability indicators that performed particularly well in the Turkish context. The evidence suggests that an index of the global stock market performs extremely well in the Turkish context. This index, which could be interpreted as a proxy for the risk appetite of global investors, exceeded its critical threshold before almost all past severe GDP per capita recessions in Turkey while sending only very few false alarms. Among domestic indicators, large positive deviations of household credit and the domestic stock market from trend also perform relatively well in signalling subsequent past severe GDP per capita recessions. The evidence is broadly robust to considering a more homogenous set of lower income OECD countries when defining the critical thresholds. Indicateurs d'alerte des récessions sévères passées en Turquie La crise financière mondiale et ses coûts économiques et sociaux élevés ont ravivé l'intérêt académique et politique pour les « indicateurs d'alerte rapide » des crises. Ce document vise à étudier la performance des indicateurs de vulnérabilité comme indicateurs d'alerte des récessions sévères passées en Turquie. Il se fonde sur un nouvel ensemble d'indicateurs de vulnérabilité récemment établi (Röhn et al., 2015), et emploie la méthode de signalisation utilisée dans Hermansen et Röhn (2015), complétée par des inspections visuelles pour détecter des indicateurs de vulnérabilité ayant particulièrement bien fonctionné dans le contexte turc. Les résultats indiquent que l'indice du marché boursier mondial performe extrêmement bien dans le cas turc. Cet indice, qui pourrait être interprété comme un proxy de l'appétit pour le risque des investisseurs mondiaux, a dépassé son seuil critique avant presque toutes les récessions sévères passées en Turquie. Il a envoyé très peu de fausses alarmes. Parmi les indicateurs intérieurs, de grands écarts positifs des crédits aux ménages, et du marché boursier par rapport aux tendances fonctionnent aussi relativement bien. Les résultats sont dans l’ensemble robustes à la considération d’un ensemble plus homogène de pays à faible revenu de l'OCDE dans la définition des seuils critiques.
