A Tractable Model of Search on the Job and Aggregate Fluctuations
In this paper, we develop a tractable model of the labor market featuring on-the-job search and aggregate fluctuations.
Repeated Moral Hazard with Worker Mobility via Directed On-the-Job Search
I develop a model of dynamic employment contracts by integrating an optimal contracting problem into an equilibrium search framework. The proposed framework enables us to analyze the interaction between the contracting problem and the endogenously evolving outside environment via worker mobility, and I characterize the optimal long-term wage contract as well as the optimal incentive compatible effort-tenure profile. The optimal contract exhibits an increasing wage-tenure profile for two reasons: 1) it induces the workers to be more likely to stay in their current contracts, and 2) it can induce the workers to make efforts when the current up-front wages cannot. The optimal incentive-compatible effort also has an increasing profile due to an interaction between 1) the workers' fear of losing their jobs, and 2) their incentive to obtain better outside offers. I then show the existence of an equilibrium. The equilibrium inherits the ``block recursivity'' developed by Shi (2008) and Menzio and Shi (2008); that is, individuals' optimal decisions and optimal contracts are independent of the distribution of workers.
Did the metamorphosis from Export Processing Zones to Special Economic Zones improve the efficiency of trade enclaves in India?
In this paper, the efficiency of seven conventional Special Economic Zones in India is analyzed, by adopting a stochastic production frontier technique, for the period between 1986–1987 and 2007–2008.Results indicate that although the efficiency scores of these enclaves have improved over the years, specifically with the introduction of the SEZ policy (2000–2001), it is far below the threshold level as identified in the literature. Besides, one can also observe a discrepancy emerging between better export earning zones and efficient zones. On the determinants side, policy intervention and large geographical area, accompanied by clustering of units, are found to have impacted the efficiency scores of these enclaves positively.
