Negative interest rates remain a controversial policy for central banks. We study a novel signalling channel and ask under what conditions negative rates should exist in an optimal policymaker’s toolkit. We prove two necessary conditions for the optimality of negative rates: a time-consistent policy setting and a preference for policy smoothing. These conditions allow negative rates to signal policy ...
This paper studies external sovereign bonds as an asset class. It compiles a new database of 266,000 monthly prices of foreign-currency government bonds traded in London and New York between 1815 (the Battle of Waterloo) and 2016, covering up to 91 countries. The main insight is that, as in equity markets, the returns on external sovereign bonds have been sufficiently high to compensate for risk. Real ...
We investigate how internal distribution motives can interfere with the economic objectives of capital controls. In order to do this, we provide a model showing that elite capture can affect optimal debt repatriations and the management of official reserves under capital controls. Relying on these theoretical insights and a wealth of quantitative and qualitative historical evidence, we study one of ...
In proxy vector autoregressive models, the structural shocks of interest are identified by an instrument. Although heteroscedasticity is occasionally allowed for in inference, it is typically taken for granted that the impact effects of the structural shocks are time-invariant despite the change in their variances. We develop a test for this implicit assumption and present evidence that the assumption ...
