Previous research, assuming linear pricing, has argued that telecommunications networks may use a high access charge as an instrument of collusion. I show that this conclusion is difficult to maintain when operators compete in nonlinear pricing: (i) As long as subscription demand is inelastic, profits can remain independent of the access charge, even when customers are heterogeneous and networks engage in second-degree price discrimination.
In 1995 The Boundaryless Organization showed companies how to sweep away the artificial obstacles — such as hierarchy, turf, and geography — that get in the way of outstanding business performance. Now, in this completely revised edition of their groundbreaking work, management experts Ron Ashkenas, Dave Ulrich, Todd Jick, and Steve Kerr offer an up-to-date version of their comprehensive guide to help any organization go "boundaryless" — and become a company with the ability to quickly, proactively, and creatively adjust to changes in the environment.
When Russia launched mass privatization, it was widely believed that it would create a powerful constituency for the rule of law. That didn't happen. We present a dynamic equilibrium model of the political demand for the rule of law and show that beneficiaries of mass privatization may not demand the rule of law even if it is the Pareto efficient "rule of the game." The reason is that uncertainty about the legal regime can lead to asset stripping, and stripping can give agents an interest in prolonging the absence of the rule of law.
This paper develops a dynamic general equilibrium model of an agricultural economy in which poor farmers borrow from rich farmers. Because output is stochastic (we allow for idiosyncratic and aggregate shocks), there may be default ex post. We compare equilibria with and without political intervention. Intervention takes the form of a moratorium and is decided by voting. When bad economic shocks are highly likely, state-contingent debt moratoria always improve ex post efficiency and may also improve ex ante efficiency. Moreover, the threat of moratoria enhances efficiency.
This paper studies the delegation as an alternative to communication. We show that a principal prefers to delegate control to a better informed agent rather than to communicate with this agent as long as the incentive conflict is not too large relative to the principal's uncertainty about the environment. We further identify cases in which the principal optimally delegates control to an "intermediary," and show that keeping a veto-right typically reduces the expected utility of the principal unless the incentive conflict is extreme.
The earnings—or rather losses—reported during the bubble were a good predictor of outcomes for dot.com firms. But are earnings the fundamental on which we should focus? The title of my talk suggests dividends as an alternative. Some analysts focus on cash flows, distrusting earnings. In the last ten years, alternative concepts like "comprehensive income," "residual income," and "abnormal earnings" have been advanced. There have been more references to book value. In addition to the profusion of new age techniques, an increasing number of fundamental attributes have been advanced.
In this paper, we develop an approach for filtering state variables in the setting of continuous-time jump-diffusion models. Our method computes the filtering distribution of latent state variables conditional only on discretely observed observations in a manner consistent with the underlying continuous-time process. The algorithm is a combination of particle filtering methods and the "filling-in-the-missing-data" estimators which have recently become popular. We provide simulation evidence to verify that our method provides accurate inference.
This paper examines characterizations of the dynamics for the first and second moments of the one-month interest rate, the 12-month excess bond return and exchange rates. The countries considered are the US, Germany, Japan, and the UK. Our tests are based on the implications of multi-country versions of the Cox et al. (1985) class of term structure models. Multi-country models are in several cases better able to explain the dynamics of the one-month interest rates and the 12-month excess bond returns than one-country models.
In this paper we argue that allowing for uncertainty resolves the controversy over the importance of life-cycle and bequest saving by showing that these motives for saving are overlapping and cannot generally be distinguished.
