In the paper, a theoretical model of the determinants of innovation behaviour and investment is developed. The model is estimated with micro-data for West- German manufacturing firms from the ifo firm panel. The empirical results reveal a positive effect from firm size and market power on...

In this paper, a theoretical model of the impact of product and process innovations on output, capacity utilization, employment, and prices is developed. The model is estimated with micro-data for West German manufacturing firms from the ifo firm panel. The empirical results reveal that...

This paper investigates the impact of technical progress on the relationship between competition an investment. Using a model of oligopoly competition with differentiated products where firms invest to reduce their marginal cost of production, I find that technical progress, which increases the...

We study how stochasticity in the evolution of agricultural productivity interacts with economic and population growth at the global level. We use a two-sector Schumpeterian model of growth, in which a manufacturing sector produces the traditional consumption good and an agricultural sector...

Travellers often combine transport services from different firms to form trip chains: e.g. first taking a train and then a bus. Integration of different forms of public and private transport into a single service is gaining attention with the concept of Mobility as a Service (MaaS). Usually the...

In this paper, we design a theoretical model to analyze the impact of the number of firms on investment in the wireless communications industry. Our model extends the Salop’s framework by introducing investment in quality that either reduces the marginal cost of production or shifts the...

The paper unveils the market structure of container shipping, which suffers by many interpretations. Existing models regress between contestability, duopoly, monopolistic competition and game theory. This paper proposes an oligopoly model with two groups of companies: oligopolists and...

Travelers often combine transport services from different firms to form trip chains: e.g. first train and then a bus. Integration of different forms of public and private transport into a single service is gaining attention with the concept of Mobility as a Service (MaaS). Usually, the focus is...

The optimal market structure in the mobile industry is an important topic in the mobile industry. In this paper, we use two theoretical frameworks and a structural estimation approach to assess the effects of market structure on consumer surplus in symmetric mobile markets. When mobile services...
