In this paper we analyse a dynamic model of investment under uncertainty in a duopoly, in which each firm has an option to switch from the present market to a new market. We construct a subgame perfect equilibrium in mixed strategies and show that both preemption and attrition can occur along...

We study Markov perfect equilibria (MPE) of two-player multi-mode differential games with controlled state dynamics, where one player controls the transition between modes. Different types of MPE are characterized distinguishing between delay equilibria, inducing for some initial conditions mode...

We study a discrete time dynamic game of price competition with spatially differentiated products and price adjustment costs. We characterise the Markov perfect and the open-loop equilibrium of our game. We find that in the steady state Markov perfect equilibrium, given the presence of...

In a framework with an upstream monopoly and a downstream duopoly, we analyze the impact of convex costs on the downstream level. In contrast to the case of constant marginal costs, vertical integration does not imply complete market foreclosure. While the non-integrated downstream firm receives...

We develop a unifying framework to investigate the effects of firms’ internet presence on productivity and market structure. Using information on website adoption as an indicator of online trading, we treat the decision of entering an e-commerce market equivalent to the decision of entering a...

In contrast to traditional business models, two-sided platforms internalize indirect network effects that exist between different groups of platform participants. The strength of the network effects has a decisive influence on the success of the platform and its market position. Markets with...

We challenge the dichotomy of network effects and highlight that they are not an exogenous characteristic of networks, but endogenous to the decisions of network users. When users choose which activities to perform in a network, multi-activity users transform indirect into direct network...

In diesem Beitrag werden die Auswirkungen sektoraler, regionaler sowie betrieblicher Determinanten auf das Scheitern junger Betriebe mit Hilfe eines ökonometrischen Überlebensdauer-Ansatzes analysiert. Dabei findet ein accelerated failure time model mit zugrunde liegender log-logistischer...

The question how the real and the financial side of a capitalist economy relate to each other has been a frequently recurring topic in the history of economic thought. Our paper addresses this question from the viewpoint that capital ultimately seeks returns from its perpetual reallocation and...

In most transition countries the aggregate level evidence suggests that most industries are just destroying jobs, due to the legacy of communism where ovfirmanning levels of employment were the nfirm. This paper sheds light on whether the transition process in Slovenian manufacturing has been...
