[pt] A TEORIA DAS EXPECTATIVAS VALE: OCASIONALMENTE / [en] THE EXPECTATIONS HYPOTHESIS HOLDS: AT TIMES

FERNANDO LUIZ MACEDO CARDOSO 25 May 2020 (has links)
[pt] Tipicamente, a literatura de curva de juros assume que taxas de juros para horizontes longos são compostas por expectativas de taxas de juros curtas que devem vigorar nesse horizonte longo e/ou um prêmio de risco. O objetivo deste trabalho é mostrar evidência de que o peso relativo de um componente expectacional vis-à-vis um componente de prêmio de risco pode depender do tempo e do estado da economia. Ademais, a probabilidade de um Regime da Teoria das Expectativas mostra-se relacionado ao ciclo de negócios. Ainda, os resultados indicam que ao se incorporar a probabilidade destes regimes, é possível intensficar o poder preditivo do diferencial entre os juros longos e o curto tanto para excesso de retornos quanto para atividade econômica. / [en] The yield curve literature typically decomposes long-term interest rates into expected future short-term rates and a risk premium. We show that the relative importance of the expectational component vis-à-vis the risk premium component can be time-varying and state-dependent. Further, the likelihood of an Expectations Hypothesis (EH) State has a clear relation to the business cycle. Moreover, our results indicate that incorporating the probability of these EH states boosts the predictive power of the benchmark yield curve measure, the term spread, both for future excess bond returns and economic activity.
