Volatility Spillovers and the Global Financial Cycle Across Economies: Evidence from a Global Semi-Structural Model

Abstract: The paper provides some evidence on the relevance of global uncertainty and risk aversion and the lesser importance of US interest rates for the global financial and business cycles. As framework, we use a global semi-structural model augmented with financial and trade interlinkages. Financial interlinkages are modelled with proposed global uncertainty, global risk aversion and global financial cycle channels. Trade interlinkages are modelled with proposed value-chain trade equations.

A rank approach for studying cross-currency bases and the covered interest rate parity

We use the recently developed panel rank-cointegration test proposed by Pedroni et al. [2015] to check for the stability conditions of the cross-country money market interest rate bases. Using weekly information on short-term interest rates and spot and forward exchange rates for a set of 20 European economies during 2005-2017, we show that in most cases these bases are non-stationary, implying the failure of the Covered Interest Rate Parity condition. Concretely, a mean-reverting behavior is encountered in only two cases.

Sovereign Risk and the Real Exchange Rate: A Non-Linear Approach

We estimate a model of real exchange rate determination which is based on interest rate, term structure and purchasing power parities. This model takes into account sovereign risk as a key determinant with possibly non-linear effects. Estimations are performed for five Latin-American economies: Brazil, Chile, Colombia, Mexico and Peru. The results show that the model has good fit for all countries and the expected sign holds for most estimated coefficients. In particular, it is found that sovereign risk has a significant positive relation with the real exchange rate.

Commodity Price Fluctuations, Core Inflation and Policy Interest Rates

The world economy has recently been hit by commodity price fluctuations, with first round effects on noncore inflation and second round effects on core inflation. The policy response to commodity price fluctuations depends on the first and second round effects as well as on the strength of the central bank reaction to noncore inflation.
