By 1989 the Michigan Panel Study on Income Dynamics (PSID) had experienced approximately 50 percent sample loss from cumulative attrition from its initial 1968 membership. We study the effect of this attrition on the unconditional distributions of several socioeconomic variables and on the...

This paper highlights the role of takeover defenses in the acquisition process. If managerial defensive effort is fixed, the unregulated level of takeover activity is lower than socially desirable since shareholders regard the financial incentives given to raiders to stimulate takeover activity...

It is widely known that when there are negative moving average errors, a high order augmented autoregression is necessary for unit root tests to have good size, but that information criteria such as the AIC and BIC tend to select a truncation lag that is very small. Furthermore, size distortions...

Ever since the development of the Autoregressive Conditional Heteroskedasticity (ARCH) model (Engle [1982]), testing for the presence of ARCH has become a routine diagnostic. One popular method of testing for ARCH is T times the R^2 from a regression of squared residuals on p of its lags. This...

According to the standard model of urban traffic congestion and urban spatial structure, congestion tolling results in a more concentrated city. In recent years, a new model of rush hour urban auto congestion has been developed which incorporates trip-timing decisions: the bottleneck model. In...

This paper establishes stochastic equicontinuity for classes of mixingales. Attention is restricted to Lipschitz-continuous parametric functions. Unlike some other empirical process theory for dependent data, our results do not require bounded functions, stationary processes, or restrictive...

This paper develops a new methodology that makes use of the factor structure of large dimensional panels to understand the nature of non-stationarity in the data. We refer to it as PANIC‹ a 'Panel Analysis of Non-stationarity in Idiosyncratic and Common components'. PANIC consists of...

Relative prices are nonstationary and standard root-T inference is invalid for demand systems. But demand systems are nonlinear functions of relative prices, and standard methods for dealing with nonstationarity in linear models cannot be used. Demand system residuals are also frequently found...

Some public policies aimed at integrating welfare recipients into the world of work are predicated on the premise that getting welfare recipients to work will change their beliefs about how they will be treated in the labor market. This paper explores the rationale for these policies and...
