This paper empirically investigates the effects of Anti-Open Grazing Laws (AOGLs) on herder-farmer conflicts in Nigeria. The laws, enacted as a response to escalating violent conflicts over fertile land resources between herders and farmers, aimed to reduce clashes by prohibiting livestock...

The correct definition of the product market and of the geographic market is a prerequisite for assessing market structures in antitrust cases. For hospital markets, both dimensions are controversially discussed in the literature. Using data for the German hospital market we aim at elaborating...

This paper explores the implications of price-dependent demand in spatial models of product differentiation. We introduce consumers with a quasi-linear utility function in the framework of the Salop (1979) model. We show that the so-called excess entry theorem relies critically on the assumption...

We apply a heterogenous coefficient spatial autoregressive panel model from Aquaro, Bailey and Pesaran (2015) to explore competition/cooperation by Berlin fueling stations in setting prices for diesel and E5 fuel. Unlike the maximum likelihood estimation method set forth by Aquaro, Bailey and...

Many health care systems aim to enhance hospital quality by encouraging competition. However, evidence on the relationship between quality and competition is inconclusive. My contribution to this literature is two-fold. Analyzing the relationship between competition and quality for the German...

What happens to the merit order of electricity markets when all electricity is supplied by intermittent renewable energy sources coupled with large-scale electricity storage? With near-zero marginal cost of production, will there still be a role for an energy-only electricity market? We answer...

Traditional specifications of export equations incorporate foreign demand as a demand pull factor and the real exchange rate as a relative price variable. However, such standard export equations have failed to explain the export performance of euro area countries during the crisis period. In...

This paper investigates the effects of global oil and food price shocks to consumer prices in Middle East-North African (MENA) countries using threshold cointegration methods. Oil and food price shocks increase domestic prices in the long run, whereby the impact of food prices dominates. While...

For spatial data with a sufficiently long time dimension, the concept of global cointegration has been recently included in the econometrics research agenda. Global cointegration arises when non-stationary time series are cointegrated both within and between spatial units. In this paper, we...

This paper examines the long-run money demand function for 11 OECD countries from 1983 to 2006 using panel data and including wealth. The distinction between common factors and idiosyncratic components using principal component analysis allows to detect cross-member cointegration and to...
