We study an industry in which an upstream monopolist supplies an essential input at a regulated price to several downstream firms. Legal unbundling means that a downstream firm owns the upstream firm but this upstream firm is legally independent and maximizes its own upstream profits. We allow...

We study an industry with a monopolistic bottleneck (e.g. a transmission network) supplying an essential input to several downstream firms. Under legal unbundling the bottleneck must be operated by a legally independent upstream firm, which may be partly or fully owned by an incumbent active in...

We investigate the cost of capital in a model with an agency conflict between inside managers and outside shareholders. Inside ownership reflects the classic tradeoff between incentives and risk diversification, and the severity of agency costs depends on a parameter representing investor...

This paper provides an overview of the sequential shift towards activating labour market and social policy in Germany. It not only shows the changes in the instruments of active and passives labour market policies but also analyzes the implications of this change for the political economy, the...

The objective of our study was to evaluate the efficiency of public, private for-profit, and private non-profit hospitals in Germany. First, bootstrapped data envelopment analysis (DEA) was used to evaluate the efficiency of a panel (n = 1,046) of public, private for-profit, and private...

Mit dem vorliegenden Aufsatz wird das Ziel verfolgt, die Erklärung der gesamtwirtschaftlichen Unternehmensinvestitionen (Ausrüstungsinvestitionen der Unternehmen und Wirtschaftsbauinvestitionen) durch die Einbeziehung von Variablen, mit denen sich Unsicherheit abbilden läßt, zu ergänzen. In...

The link between investment and finance usually enters the empirical literature in the form of financial constraints which are defined as the wedge between the costs of internal and external finance or as the risk of being rationed on the credit market. In this context, the sensitivity of...

This paper examines the link between liquidity constraints and investment behavior for German firms of different sizes from 1970 to 1986. Results indicate that medium sized firms appear to be more liquidity constrained in their investment behavior than either the smallest or largest firms in the...

This paper uses a large panel of survey data on German firms in the manufacturing sector to analyse the effects of financing constraints for investors in general and for innovative firms in particular. Survey data with information on financing conditions are potentially a valuable tool that...

The impact of uncertainty on firms' investment outlays is subject to an ongoing debate. Theory identifies several channels. Irreversibility, financing constraints and risk aversion make a negative relationship between uncertainty and investment likely. On the other hand, the ability of firms to...
