چکیده
This paper investigates a vertical market structure called joint ownership, where a monopolistic upstream firm is jointly owned and operated by competing downstream firms. As such, a common interconnection price to an upstream bottleneck is determined by bargaining among the downstream firms. We show that (1) joint ownership can be superior to the other ownership structures by overcoming vertical externality of double marginalization; (2) collusive outcomes, however, may arise surrounding the setting of common interconnection price; (3) an overall performance of joint ownership depends crucially upon how equity shares are initially distributed and which bargaining rules are employed; and finally (4) a policy measure to promote downstream competition may have ambiguous consequences under joint ownership. Some managerial and political implications in implementing joint ownership in practice are also provided. 1999 Elsevier Science Inc. All rights reserved.

Okun’s coefficient is estimated from U.S. quarterly data covering the period 1947:1–1992:2. The cyclical components of unemployment and output are extracted by smoothing using the Kalman filter as applied to Harvey’s structural time series model. The estimated Okun’s coefficient is around 20.38 irrespective of the whether the model used is static or dynamic and irrespective of the lag length in...

We present a model of the propagation process of bank runs. A bank failure alone is not sufficient to trigger a panic. In accord with the empirical evidence, runs become contagious only during periods of macroeconomic instability. In addition, we make a clear distinction between illiquidity and insolvency as possible causes of bank failures. We also show that, despite the possibility of runs, t...

This article constructs an economic model of a rational trader who operates in a market with transaction costs and noise trading. The level of trading affects the rational trader’s marginal cost of transacting; as a result, trading volume (through its effect on marginal cost) is a source of risk. This engenders an equilibrium relationship between returns and volume. The model also provides a si...

Intertemporal budget policies are assessed in an endogenous growth model with nominal assets. The paper provides relative rankings of policies and policy instruments in terms of the tax liabilities of the private sector necessary to guarantee intertemporal government budget solvency and in terms of the welfare of the representative agent. The role of nominal assets is shown to be of relative im...

This paper explores the welfare consequences of foreign investment taxation in a small open economy, based on the notion that the true productivity of imported capital may be unknown to policy-makers. It is shown that while asymmetric information between capital importers and the host government precludes the use of a productivity specific policy measure, an across-the-board policy suffers from...
