In this paper, we consider estimation of discrete response models exhibiting conditional heteroskedasticity of a multiplicative form, where the latent error term is assumed to be the product of an unknown scale function and a homoskedastic error term. It is first shown that for estimation of the...

We propose an estimation procedure for a semiparametric panel data censored regression model in which the error terms may be subject to general forms of nonstationarity. Specifically, we allow for heteroskedasticity over time and a time varying factor load on the individual specific effect....

Powell's (1984, Journal of Econometrics 25, 303}325) censored least absolute deviations(CLAD) estimator for the censored linear regression model has been regarded asa desirable alternative to maximum likelihood estimation methods due to its robustnessto conditional heteroskedasticity and...

Since the Morris worm was released in 1988, Internet worms continue to be one of top security threats. For example, the Conficker worm infected 9 to 15 million machines in early 2009 and shut down the service of some critical government and medical networks. Moreover, it constructed a massive...

The trend of UK logistics warehouses is reported towards larger and more centralized systems on which automation is heavily invested in recent years. This is partially because of the disadvantage of manual operation resulting in the slow storage and retrieval speed, the high labor cost, and the...

The bargaining process and its role in price discovery within the Pacific Northwest asparagus industry is analyzed using a general empirical bargaining model. Growers’ and processors’ inverse supply and demand functions define boundaries for the negotiated prices. OLS and Heckman’s two-stage...

Five National Fire Danger Rating System indices (including the Ignition Component, Energy Release Component, Burning Index, Spread Component, and the Keetch-Byram Drought Index) and the Fosberg Fire Weather Index are used to characterise US fire danger. These fire danger indices and input...
