Omittedvariable bias is thus a major potential problem. Another reason for 'overspecifying' models is to avoid an 'omittedvariable bias'. Either the correlation was a coincidence, or perhaps both variables were caused by some common trend or perhaps by an omittedvariable. In most respects the two approaches (parsimony or avoiding a possible omittedvariable problem) trade off. In order to mitigate potential omittedvariable bias, we include the lagged dependent variable. The lagged dependent variable should capture problems of omittedvariable bias and specification error. By the theoretical argument of the book, this must introduce omittedvariable bias. Thus, a control is necessary to preclude omittedvariable bias. To avoid omittedvariable bias and to evaluate the robustness of the results we add several control variables. Moreover, omitting one of the variables would result in omittedvariable bias. By omitting controls for them, we potentially introduce an omittedvariable bias into the results. It uses first differencing, period-specific time dummies, and a lagged dependent variable to mitigate omittedvariable bias. First differencing, inclusion of year-specific time dummies and a lagged dependent variable can mitigate omittedvariable bias, but it cannot fully avoid it. Also, we do our best to mitigate potential omittedvariable bias, but cannot exclude the possibility that some bias remains. On a cautionary note, much research has underscored the importance of the topic in influencing the choice of language - an omittedvariable of the current study. This method suffers from omittedvariable problems due to the omission of the determinants of inefficiency at the first stage estimation of the production function. With panel data, the technique of first differencing the data can wipe out any time-invariant country effect, which eliminates already one important source of potential omittedvariable bias. If the omittedvariable, risk level, is going to bias downwards it would be necessary for the level of risk and the shadow value of biomass to be positively correlated. It is possible that campaign finance regulations and prices might both be determined by an omitted variable but whatever this might be, it is not the electoral system. If so, the relationship between growth and school enrollment rates may be spurious, simply reflecting the effect of an omittedvariable-the size of the primary sector.
