The concept of predictive regressions has been studied for over the past 20 years and its application is particularly present in applied economics, finance and econometrics. The basic set-up in the predictive regression framework associates the noisy explained variable with the lagged persistent regressor, which can be characterized as a process close to the unit root process. In my work I describe the relevance and implications of an adoption of the linear predictive regressions in forecasting the volatile stock return using the lagged variable, dividend-price ratio, which is highly persistent. Subsequently, I aim to answer questions whether the excess stock returns are predictable using dividend yields and whether the predictability is stable over time. The analysis I conduct, based on financial data, aim to detect the hypothetical presence of structural breaks in the model. In order to search for the structural instability of coefficients I construct a Wald test for each possible structural break location and investigate the accuracy of the SupWald statistic and its tabulated critical values in the framework described. Having obtained the test statistic for each of the possible break-points, I describe predictive power of explanatory variable and provide economic rationale to support some of the statistical outcomes.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This work explores the concept of predictive regressions and its application in forecasting stock returns using dividend yields. The main objective is to assess whether the predictive power of dividend yields is stable over time, particularly focusing on the presence of structural breaks. The study aims to determine if the excess stock returns are predictable using dividend yields and if this predictability is consistent over time. The analysis also seeks to identify potential structural breaks in the model and analyze their impact on predictive power.

Frequently Asked Questions
What is a linear predictive regression framework?
It is an econometric model used to forecast a noisy explained variable (like stock returns) using a lagged, persistent regressor (like the dividend-price ratio).
Can dividend yields predict stock returns?
The study investigates this possibility, noting that while dividend yields are often used as predictors, their predictive power can be unstable due to structural breaks in the market.
What are structural breaks in financial models?
Structural breaks are sudden shifts in the relationship between variables, often caused by major economic events, which can make historical forecasting models inaccurate.
How do you test for structural instability?
The framework uses statistical tests like the Wald test and the SupWald statistic to identify the location and significance of potential breaks in the model's coefficients.
Why is the dividend-price ratio characterized as a "persistent" regressor?
In econometrics, persistence means the variable's current value is highly correlated with its past values, often behaving similarly to a unit root process, which requires specific modeling techniques.
