For several years, an increasing number of firms are investing in Open Source Software (OSS). While improvements in such a non-excludable public good cannot be appropriated, companies can benefit indirectly in a complementary proprietary segment. We study this incentive for investment in OSS. In...

The existing literature on "two-sided markets" addresses participation externalities, but so far it has neglected pecuniary externalities between competing platforms. In this paper we build a model that incorporates both externalities. In our setup differentiated platforms compete in advertising...

Linear demand formulations for price competition in horizontally differentiated products are sometimes used to compare situations where additional varieties become available, e. g. due to market entry of new firms. We derive a consistent demand system to analyze such situations.

In many countries entrepreneurship is promoted through tax reductions for small businesses and by various government support schemes. We analyze the effects of such policies to subsidize small businesses in a setting where both the risk-return characteristics of the selected innovation project...

In the framework Hotelling-Downs competition two players can freely choose a position along a one-dimensional market. We introduce restrictions of feasible strategies and analyze the consequences for players and consumers. In equilibrium players may minimally differentiate away from the center...

This paper is set to investigate the existence of spillover effects for the trading process of correlated financial instruments. While the main literature in price impact models has focused mainly on multivariate processes for a unique asset, we argue that transitory spillover effects in such...

Agglomeration brings costs (e.g., intensified local competition) as well as benefits (e.g., knowledge spillover). It is important to examine the net impact of agglomeration to understand the geographic distribution of economic activities. In this study, we use firm markup (defined as the ratio...

Do institutions spatially affect growth? By employing a neoclassical growth model with institutional controls and augmenting the model with a formal spatial framework, this study finds evidence that institutions has spatial spillover effect on economic growth based on a panel observation from 58...
