We prove existence, monotonicity and differentiability of firm profits and provide first-order conditions that characterize the properties of the optimal contract. We demonstrate how the shape of the contract depends on the persistence and variance of the productivity process, on worker and firm...

Extensive literature demonstrates that workers with high tenure suffer large and persistent earnings losses when they are displaced. We study the reasons behind these losses in a tractable search model that includes a lifecycle dimension, endogenous job mobility, and worker- and...

We study optimal capital taxation in a dynamic Mirrleesian model with time-nonseparable preferences. The model covers the widely used cases of habit formation and durable consumption. Time-nonseparable preferences change labor supply incentives across time and thereby generate novel motives to...
