what is the unit root in bread is the error term in a loaf of bread uncorrelated over time is wage and bread cointegrated what is the unit root of wage which of the following is a proof that there is no autocorrelation between the wage and bread why is the unit root of $bread uncorrelated is bread_i an autocorrelation? how is the error term $epsilon can the units of a payoff be cointegrated when we assume that the bread is noncorrelated over time is the unit root in salary uncorrelated how do we know that there is no autocorrelation when you find out that the bread is cointegrated what is the autocorrelation of income what is the autocorrelation between wage and bread does bread have any coherence does bread have autocorrelation? what does a u_sigma do with salary what is the unit root for the bread is a wage cointegrated with a bread
