In this paper we analyze the determinants of export sophistication based on a large panel dataset (2001-2014; 101 countries) and using different estimation algorithms. Using Monte Carlo simulations we evaluate the bias properties of estimators and show that GMM-type estimators outperform...

I evaluate German export growth and import growth forecasts published by eight professional forecasters for the years 1971 to 2019. The focus of the evaluation is on the weak and strong efficiency as well as the unbiasedness of the forecasts. To this end, I use a novel panel-data set and...

This paper reexamines the issue of long-run PPP using multiple panel tests in the framework of confirmatory analysis. Application of six panel tests under competing null hypotheses to the real exchange rates of 21 industrial countries yields seemingly contradictory evidence on the parity during...

Recent studies of purchasing power parity (PPP) use panel tests that fail to take into account heterogeneity in the speed of mean reversion across real exchange rates. In contrast to several other severe restrictions of panel models and tests of PPP, the assumption of homogeneous mean reversion...

Many estimates of early-warning-system (EWS) models of currency crisis have reported incorrect standard errors because of serial correlation in the context of panel probit regressions. This paper documents the magnitude of the problem proposes and tests a solution and applies it to previously...

The 2008 financial crisis has rekindled interest in the issue of early warning signals (EWS) of financial distress. It has also triggered renewed interest in the literature on currency crises, with many countries, especially among emerging market economies, experiencing severe exchange market...

This paper investigates the performance of the IMF WEO growth forecast revisions across different horizons and country groups. We find that: (i) growth revisions in horizons closer to the actual are generally larger, more volatile, and more negative; (ii) on average, growth revisions are in the...

The relationship between exchange-rate volatility and aggregate export volumes for 12 industrial economies is examined using a model that includes real export earnings of oil-producing economies as a determinant of industrial-country export volumes. A supposition underlying the model is that,...

This paper investigates the impact of the exchange rate regime on the current account adjustment process. In a first step, the present analysis assesses previous empirical work supporting the predominant view that more flexible exchange rate regimes facilitate current account adjustments. Using...
