Dieses Gutachten untersucht den Zusammenhang von Mengen‐ und Kostenveränderungen in der stationären Krankenhausversorgung. Ziel ist die Bestimmung des Fixkostenanteils an den Fallpauschalen (G‐DRG) für zusätzliche Leistungen. Für diese Fragestellung wird ein empirischer Ansatz auf...

Most international commerce is carried out by multinational firms, which use their foreign affiliates for the majority of their foreign sales. In this paper, I examine the determinants of multinational firms' location and production decisions and the welfare implications of multinational...

We study contestability in non-profit markets when non-commercial providers supply a homogeneous collective good through increasing-returns-to-scale technologies. Unlike in the case of for-profit competition, in the non-profit case the absence of price-based sales contracts means that fixed...

This paper explores the implications of price-dependent demand in spatial models of product differentiation. We introduce consumers with a quasi-linear utility function in the framework of the Salop (1979) model. We show that the so-called excess entry theorem relies critically on the assumption...

The aim of this paper is to explore the patterns of trade duration across regions and to identify its determinants. Using an extended Cox model, we evaluate the effects of country and product characteristics, as well as of trade cost variables on the duration of trade relationships from 96...

"Fixed transaction costs and delivery lags are important costs of international trade. These costs lead firms to import infrequently and hold substantially larger inventories of imported goods than domestic goods. Using multiple sources of data, we document these facts. We then show that a...

Barriers to entry are regarded as major impediments to the working of markets. Entry must not necessarily actually take place - the perceived threat of entry may encourage incumbent firms to behave as if they are in a competitive market, even if they are not. We present empirical evidence on...
