A novel procedure is applied to test for switches between hysteresis and the natural rate theory over more than a century of UK and USA unemployment data. For both the countries we see a period conforming to hysteresis starting in the early 1920s for the UK and 1930 for USA

Commodity price shocks are an important type of external shock and are often cited as a problem for economic growth in Sub-Saharan Africa. We choose nine Sub Saharan African countries that are heavily dependent on a single agricultural commodity for a significant portion of their income. This...

A novel procedure is applied to test for switches between hysteresis and the natural rate theory over more than a century of UK and USA unemployment data. For both the countries we see a period conforming to hysteresis starting in the early 1920s for the UK and 1930 for USA.

The aim of this study is to analyze the potential risk premium inherent in the uncovered interest parity (UIP) condition. The component GARCH-in-mean model is used to measure the time-varying risk premium in UIP and separates the permanent and transitory risks. The results show that the risk...

This study considers the nonlinear relationship between the expected exchange rate change and the interest rate differential, using STR models (ESTR and LSTR), with Sharpe ratios, interest rate differentials and exchange rate volatilities as the transition variables. The results generally...
