Previous studies have shown that cross year peer tutoring programmes in medical education can enhance the skills of volunteer tutors and learners alike [ 2, 4, 8].
Finally, this study draws on cross year, treatment, and environment data, which allows us to better understand how traits interact with each other, as well as with the environment.
Our paths crossed years before we ever met.
Half an hour later — or is this on another crossing, years later?
Their paths crossed years later in New York, when Mr. White found Mr. Edwards hanging out with drug dealers on a street corner in the Bronx.
Their paths crossed years ago — a month after Colorado took Wedge from Boston in the November 1992 expansion draft, the Red Sox wanted a catcher and signed Melvin as a free agent.
Instead, I use a more simple approach based on indirect inference to compute cross-year autocorrelations.
The optimal value of the cross-year autocorrelation (rho ^_{k}) is the (rho _{k}) which minimizes the absolute distance between (hat{lambda }^) and any (hat{lambda }_{k}).
Since the only unknown in (mathbb {E} tilde{W}_{i,t + h})) is the value of (rho )—the cross-year autocorrelation of interest based on a grid of 40 values of (rho ) from 0 to 0.975 on 0.025 intervals, I generate (mathbb {E} tilde{W}_{i,t + h}, |, _{rho, =, rho _{k}})) where (k, =, 1,ldots, 40).
Notably, Barff and Knight [13] propose a dynamic shift-share analysis that applies the traditional analysis to cross-year data, a method that is adopted in many subsequent studies (e.g., Hirobe [18]; Kobayashi [19]; Mitchell and Carlson [20]; Nissan and Carter [21]; Shi et al. [22]).
Hence, wages throughout the period of interest 1988–2011 can be fully characterized by the mean and variance of log daily wages in each period—estimated in Eq. (1)—and the cross-year autocorrelations of log daily wages for every pair of years.15 Haider and Solon (2006) estimate autocorrelations between pairs of years using a bivariate Tobit maximum-likelihood estimator.
