We investigate the impact of competition policy enforcement on the functioning of European energy markets while accounting for sectoral regulation. For this purpose, we compile a novel dataset on the European Commission's (EC) and EU member states' competition policy decisions in energy markets and combine it with firm- and sector-level data. We find that EC merger policy has a positive and robust ...

We empirically study the effects of broadband internet diffusion on local election outcomes and on local government policies using rich data from the U.K. Our analysis shows that the internet has displaced other media with greater news content (i.e. radio and newspapers), thereby decreasing voter turnout, most notably among less-educated and younger individuals. In turn, we find suggestive evidence ...

How do courts award noneconomic damages? Does it matter if the state is the defendant? This article addresses these questions in the context of medical malpractice appeals to the Spanish Supreme Court. Moreover, this study provides the first empirical analysis of the quantification of noneconomic damages in medical malpractice cases in administrative courts, where the state is the defendant, and in ...

Against the background of remunicipalisation trends in European public service sectors, this paper estimates firm-level productivity for German electricity retailers and tests whether the ownership type has a significant impact on productivity. We specify a production function for the retail sector with labour and external services as main inputs, which is estimated using a control function approach. ...

The tertiarisation, or perhaps more accurately, the deindustrialisation of the economy has left deep scars on cities. It is evident not only in the industrial wastelands and empty factory buildings, but also in the income and social structures of cities. Industrialisation, collective wage setting, and the welfare state led to a stark reduction in income differences over the course of the 20th century. ...

Revenue cap regulation is often combined with systematic benchmarking to reveal the managerial inefficiencies when regulating natural monopolies. One example is the European energy sector, where benchmarking is based on actual cost data, which are influenced by managerial inefficiency as well as operational heterogeneity. This paper demonstrates how a conditional nonparametric method, which allows ...

We compare three recently developed frontier estimators, namely the conditional DEA (Daraio and Simar, 2005; 2007b), the latent class SFA (Greene, 2005; Orea and Kumbhakar, 2004), and the StoNEZD approach (Johnson and Kuosmanen, 2011) by means of Monte Carlo simulation. We focus on their ability to identify production frontiers and efficiency rankings in the presence of environmental factors. Our simulations ...

We study the effects of reminders on people’s behavior in investment activities characterized by up-front costs and delayed benefits, such as getting an education and maintaining a healthy lifestyle. We conduct a field experiment and show that simple weekly reminders induce users of a gym to substantially increase their gym attendance over an extensive period. Users’ response to reminders is immediate ...

This paper analyses whether exporting firms are less CO2 emission-intensive than non-exporting competitors. It exploits a novel and unique dataset for Germany, a major exporting country. Due to the direct link between CO2 emissions and fuels consumed, we argue that it is necessary to employ a production function framework to consistently analyse CO2 emission intensity. We show that such an approach ...

We analyze the pass-through of cost changes to retail tariffs in the German electricity market over the 2007–2014 period. We find an average pass-through rate of around 60%. This significantly varies with demand factors: while the pass-through rate to baseline tariffs, where firms have greater market power because customers are less willing to switch, is only 50%, it increases to 70% in the competitive ...
