Jürgen Wolters faculty members in Education, Science, and Engineering, as well as school teachers joined forces to produce a resource bank of innovative and tested instructional materials that are transforming teaching in the K-12 classroom. Many of the instructional materials cross traditional disciplinary bound

Jürgen Woltersided by an adult who keeps the child’s attention focused as the story unfolds. Occasionally, children are given a tablet or smartphone to operate on their own when the adult is not available to scaffold (e.g., in a car, at a restaurant). Although traditional paper storybooks still dominate the presc

The Linear Dynamic Econometric Model,motions. Later, Yule (1927) and Slutzky (1937) apply an autoregressive and a moving average scheme, respectively. They show that these series have many of the apparent cyclic properties which characterize economic time series.

Spectral Representation of the Linear Dynamic Model with Constant Coefficients,l known (see e.g. König and Wolters (1972a, p.56)), these figures are, in general, difficult to interpret. Moreover, the variances and covariances do not give direct measures of the intensity and of the connection of different cycles respectively.

Spectral Representation of a Linear Dynamic Econometric Model with Stochastic Coefficients,eters according to the classical theoretical specification of these models. In the sequel an approach which explicitly considers the stochastic nature of the estimated regression coefficients in order to test the Frisch hypothesis is applied. Hence, besides the uncertainty originated by the specific

Effects of Exogenous Variables on the Cyclic Properties of an Econometric Model,roperties (Menges (1977)) and the judgement of policy measures. For instance, Goldfeld and Blinder (1972) discussed whether policy variables, generally treated as exogenous, should be treated as endogenous assuming the policymaker pursues an active counter-cyclical policy during the period of invest
