We propose residual based tests for cointegration using local GLS detrending (Elliott, Rothemberg and Stock (1996), ERS) to eliminate separately the deterministic components in the series. We consider two cases, one where only a constant is included and one where a constant and a time trend are...

This paper obtains asymptotic expansions of the frequentist distributions of modified likelihood ratio statistics when the observations are discrete. An upper bound of the uncertainty due to the discrete nature of the observations is obtained, slightly larger than Yarnold's result (obtained in...

While contract theory has reached a high degree of sophistication, econometric applications remain scarce. One often invoked reason is that adequate data is hard to find. We argue that insurance data fit the requirements of econometric testing especially well. Then we propose some insights on...

We address the general issue of econometric specifications of dynamic asset pricing models, which cover the modern literature on conditionally heteroskedastic factor models as well as equilibrium-based asset pricing models with an intertemporal specification of preferences and market fundamentals.

For the statistical analysis of the ARMA models, the standard method requires that the linear innovations are martingale differences. This assumption is not satisfied for ARMA representations of non-linear processes. In such a case the standard method tipically entails an underestimation of the...

This paper has pushed Becker's matching insights into a quite plausible search setting. Exploiting the implicit integral equation (10), we gave a thorough characterization of cross-sectional matching patterns in the equilibrium and constrained s ocial optimum of a frictional matching model. In...

A brief overview is given of some problems in econometric model building. We discuss, by example, the concept of a time series, a random walk, and integrated variable and the notion of cointegration and common trends.

In this report Appelbaum's model is discussed in detail. The model is also applied to the Dutch construction sector, allowing the degree of collusion to be ascertained. The model consists of five equations. One equation, the mark-up equation, is derived from the assumption of profit maximization...
