The paper applies an equilibrium correction model to discuss impacts of monetary, labour and external factors on the German inflation. The approach presented is of eclectic character and allows for examination which variables representative for various inflation theories matter empirically when...

A recent literature has used variation just around deterministic legislative population thresholds to identify the causal effects of institutional changes. This paper reviews the use of regression discontinuity designs using such population thresholds. Our concern involves three arguments: (1)...

In this paper we investigate the link between entrepreneurship and financial constraints. We develop a dynamic partial equilibrium model of an individual utility maximization that predicts that the person is more likely to start her business when financial constraints are eased. We test this...

This paper examines whether exporting activity matters for firm's price cost margins. The recent literature on exporting and productivity shows that exporters on average are more efficient than nonexporters. If that is the case we may also expect them to have different mark-ups. We investigate...

This paper empirically analyzes the causal relationship between migration and human trafficking inflows into Germany during the period between 2001 and 2010. My results suggest that migrant networks, measured by migrant stocks from a specific source country, increase the illicit, exploitative...

This paper empirically analyzes the relationship between migration and human trafficking inflows into Germany during the period between 2001 and 2010. My results suggest that migrant networks, measured by migrant stocks from a specific source country, have a causal linkage with the illicit,...

We analyze duopoly Bertrand competition under network effects. We consider both incompatible and compatible products. Our main result is that network effects create a fundamental conflict between the maximization of social welfare and consumer surplus whenever products are incompatible. While...

We model competition between two unregulated mobile phone companies with price-elastic demand and less than full market coverage. We also assume that there is a regulated full-coverage fixed network. In order to induce stronger competition, mobile companies could have an incentive to raise their...

We analyze market dynamics under Bertrand duopoly competition in industries with network effects and consumer switching costs. Consumers form installed bases, repeatedly buy the products, and differ with respect to their switching costs. Depending on the ratio of switching costs to network...

We consider a model with two firms operating their individual networks. Each firm can choose its price as well as its investment to build up its network. Assuming a skewed distribution of consumers, our model leads to an asymmetric market structure with one firm choosing higher investments....
