We analyze how network regulation affects investment into network infrastructure and complementary services. While regulation negatively affcets investment incentives in the regulated network market, the effects of network regulation on investment in complementary services can be either negative...

Ex ante evaluation of policy reform proposals in general relies either on microsimulation models or computable general equilibrium (CGE) models. This paper describes how the Centre of European Economic Research (ZEW) has merged two established models - the so-called STSM and PACE-L models – in...

The specification of parameters is a crucial task in the development of economic models. The objective of this paper is to improve the standard parameter specification of computable general equilibrium (CGE) models. On that account, we illustrate how Optimal Fingerprint Detection Methods (OFDM)...

The formulation of market equilibrium problems as mixed complementarity problems (MCP)permits integration of bottom-up programming models of the energy system into top-down general equilibrium models of the overall economy. Despite the coherence and logical appeal of the integrated MCP approach,...

We motivate the formulation of market equilibria as a mixed complementarity problem (MCP) in order to bridge the gap between bottom-up energy system models and top-down general equilibrium models for energy policy analysis. Our objective is primarily pedagogic. We first lay out that the MCP...

This chapter reviews options of labor market modelling in a CGE framework. On the labor supply side, two principal modelling options are distinguished and discussed: aggregated, representative households and micro simulation based on individual household data. On the labor demand side, we focus...

This paper analyses the interplay between international trade, regional adaptation and North-to-South transfers for funding adaptation within the framework of a dynamic computable general equilibrium model, where impacts of climate change depend on changes in precipitation and temperature. If...

Developments in the EU telecommunications markets require a recurrent redesign of the regulatory framework for telecommunications services. In this regard, the analysis of the substitution effects between different types of telephony is the cornerstone of market definition and therefore of...

OTT-messenger such as facebook, WhatsApp have gained wide popularity among mobile users while traffic of text messaging has been in strong decline in several countries. This work is the first to provide an empirical analysis how consumption of OTT-messengers affects demand for text messaging and...

Although the future socio-economic benefits of a new fibre-based (“next generation access”, NGA) telecommunications infrastructure seem to be uncontroversial, a universal NGA coverage appears to be a rather unrealistic objective without government intervention. We contend, however, that the...
