In this paper, we study the incumbent's incentive to share its essential facility when there exist network effects. We show that without network effects, the incumbent will charge an access fee high enough to deter the entry. with network effects, however, the incumbent always has an incentive...

The purpose of this paper is to investigate the impact of exchange rate volatility on exports among 14 Asia Pacific countries, where various measures to raise the intra-region trade are being implemented. The empirical tests using annual data for the period from 1980 to 2002 detect a significant...

Volatility models have been playing an important role in economics and finance. Using a multivariate generalized spectral approach, we propose a new class of generally applicable omnibus tests for univariate and multivariate volatility models. Both GARCH models and stochastic volatility models...

This paper derives conditions under which the generalized method of moments (GMM) estimator is as efficient as the maximum likelihood estimator (MLE). The data are supposed to be drawn from a parametric family and to be stationary Markov. We study the efficiency of GMM in a general framework...

This paper studies passengers' choice behavior in air travel. Products are defined as a unique combination of airline and flight itinerary while markets are defined as a directional round-trip air travel between an origin and a destination city. A structural econometric model is used to...

In this paper, we use a maximal invariant likelihood (MIL) to construct two likelihood ratio (LR) tests. The first involves testing for the inclusion of a non-linear regressor and the second involves testing of a linear regressor against the alternative of a non-linear regressor. We report the...

This paper presents an accumulation-driven growth model where investment depends on public policy which in turn depends on economically important fundamentals. It is argued that conditioning on factor accumulation in growth regressions that also include policy variables may be problematic. When...

This paper considers the parametric inference of a wide range of structural econometric models. The class of models considered includes those with parameter-dependent support and those derived from game-theoretic models. Inference of those models has raised some important econometric issues....

Within the independent private-values paradigm, we derive the data-generating process of the winning bid for the last unit sold at sequential English auctions when bidder valuations are draws from one of several different classes of distributions; i.e., in the presence of asymmetries. When the...

Congress enacted The Americans with Disabilities Act of 1990 over the protests of small business advocates who claimed that the ADA would trigger a wave of bankruptcies. Although the profitability of firms may suffer from the costs of ADA compliance, no systematic evidence is available. This...
