This paper explores the use of informal credit as a strategy for managing risks by market women in northern Ghana. A broad concept of the costs of risk management strategies is introduced and encompasses both a time and monetary dimension. Based on qualitative data, the analysis reveals that...

This paper estimates ordered logit and probit regression models for bank ratings which also include a country index to capture country-specific variation. The empirical findings provide support to the hypothesis that the individual international bank ratings assigned by Fitch Ratings are...

We model EU countries' bank ratings using financial variables and allowing for intercept and slope heterogeneity. Our aim is to assess whether old and new EU countries are rated differently and to determine whether new ones are assigned lower ratings, ceteris paribus, than old ones. We find that...

The GARCH(1,1) model and its extensions have become a standard econometric tool for modeling volatility dynamics of financial returns and port-folio risk. In this paper, we propose an adjustment of GARCH implied conditional value-at-risk and expected shortfall forecasts that exploits the...

This paper examines the Taylor rule in five emerging economies, namely Indonesia, Israel, South Korea, Thailand, and Turkey. In particular, it investigates whether monetary policy in these countries can be more accurately described by (i) an augmented rule including the exchange rate, as well as...

This paper applies a microeconomic-based stylized model to identify the optimal modal split of water supply infrastructure in regions of the Global South against the background of the Sustainable Development Goal (SDG) No. 6. We assume a linear city, with some plausible assumptions on income and...

This paper analyses the long-memory properties of both the conditional mean and variance of UK real GDP over the period 1851-2013 by estimating a multivariate ARFIMA-FIGARCH model (with the unemployment rate and inflation as explanatory variables). The results suggest that this series is...

Dieser Beitrag möchte einen Impuls zur stärkeren Berücksichtigung von Genderaspekten in makroökonomischen Modellen geben. Am Beispiel der Philipps-Kurve geht es um die Frage, ob sich das Erwerbsverhalten von Frauen und Männern so stark voneinander unterscheidet, dass sich dies im Verlauf...

We study the determinants of sovereign bond yield spreads across 10 EMU countries between Q1/1999 and Q1/2010. We apply a semiparametric time-varying coefficient model to identify, to what extent an observed change in the yield spread is due to a shift in macroeconomic fundamentals or due to...

The German potable water supply industry is regarded as being highly fragmented, thus inhibiting high potentials for efficiency improvements through consolidation. Focusing on a hypothetical restructuring of the industry, we apply Data Envelopment Analysis (DEA) to analyze the potential...
