The ethnosizer, a new measure of the intensity of a person's ethnic identity, is proposed using information on language, culture, societal interaction, history of migration, and ethnic self-identification. A two-dimensional version classifies immigrants into four states: integration, assimilation, separation and marginalization. Results based on the German Socio-economic Panel for 2001 are as follows. ...

This paper expands Shleifer's (Rand J Econ 16:319-327, 1985) theory of yardstick competition and develops a modified yardstick competition mechanism (MYC), where the yardstick employed consists of a tariff basket and total costs. This mechanism has a significant information advantage: the regulator "only" needs to observe total costs, prices and output of all firms. The MYC mechanism can ensure a socially ...

In this study we compare the traditional OLS approach applied to the log-linear form of the gravity model with the Poisson Quasi Maximum Likelihood (PQML) estimation procedure applied to the non-linear multiplicative specification of the gravity model. We use the trade flows for all products, for all manufacturing products as well as for manufacturing products broken down by three-digit ISIC Rev.2 ...

This paper examines success factors for five emerging innovations in the electricity system under the influence of current environmental and economic paradigms such as climate policy and market liberalisation. It widens the conventional focus on technological innovations to encompass organisational and behavioural innovations. The investigation builds on five empirical studies of recent developments ...

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 reciprocal mobile-to-mobile access charges above the marginal costs of termination. Stronger competition ...

Most models that are used to analyze support policies for renewable electricity neglect important market features like oligopolistic behavior, emission trading, and restricted cross-border transmission capacities. We use a quantitative electricity market model that accounts for these aspects and decompose the impact of the German Feed-in tariff (FIT) into two frequently counteracting effects: a substitution ...

This article introduces a special issue on the micro-level dynamics of mass violent conflict. While most analyses of conflict typically adopt a regional, national or global perspective, often using country-level data, this special issue takes an explicit micro-level approach, focusing on the behaviour and welfare of individuals, households and groups or communities. At a fundamental level, conflict ...

This article analyzes the effects of household-level activity choices on farm household welfare in a developing country affected by mass violent armed conflict. The study uses household survey data from postwar Nampula and Cabo Delgado provinces in Northern Mozambique capturing many activity choices, including market participation, risk and activity diversification, cotton adoption, and social exchange, ...

In Europe, two market designs are discussed for electricity trade and transmission. We argue that their performance in the presence of market power can be represented by two models from the literature. In contrast to examples for simple two-node networks, we show that in more complex networks a general ranking of both designs is not possible. Hence, computational models are required to evaluate the ...
