While using detailed firm-level data from the private business sector, this study identifies two empirical puzzles: (i) returns-to-scale (RTS) parameter estimates rise at higher levels of data aggregation and (ii) estimates from the firm level suggest decreasing returns to scale. The analysis...

The authors formulate a stochastic infinite-horizon insider-outsider model that is solved explicitly and used to investigate the consequences of alternative 'seniority' rules for wage and employment determination. The model is simple enough to allow analysis of several different institutional...
