Biased managers, organizational design, and incentive provision
2004-02-01We model the tradeoff between the balance and the strength of incentives implicit in the choice between hierarchical and matrix organizational structures. We show that managerial biases determine which structure is optimal: ... -
Centralized decision making and informed lobbying
2017-11We address the trade- off between centralized and decentralized decision making subject to influence from privately informed lobbies. We focus on informative equilibria with separating differentiable contribution schedules ... -
Common agency and public good provision under asymmetric information
2010-05The provision of public goods under asymmetric information has most often been viewed as a mechanism design problem under the aegis of an uninformed mediator. This paper focuses on institutional contexts without such a ... -
Common agency with informed principals
2004-06-01We analyze a common agency game under asymmetric information on the preferences of the non-cooperating principals in a public good context. Asymmetric information introduces incentive compatibility constraints which ... -
Common agency with informed principals
2004-04-29We analyze a common agency game under asymmetric information on the preferences of the non-cooperating principals. Asymmetric information introduces incentive compatibility constraints which rationalize the requirement of ... -
A contractive method for computing the stationary solution of the euler equation
2002-09-01A contractive method for computing stationary solutions of intertemporal equilibrium models is provide. The method is is implemented using a contraction mapping derived from the first-order conditions. The deterministic ... -
Contributions to the Theory of Optimal Tests
2013-10-28This paper considers tests which maximize the weighted average power (WAP). The focus is on determining WAP tests subject to an uncountable number of equalities and/or inequalities. The unifying theory allows us to obtain ... -
A critical value function approach, with an application to persistent time-series
2016-06-06Researchers often rely on the t-statistic to make inference on parameters in statistical models. It is common practice to obtain critical values by simulation techniques. This paper proposes a novel numerical method to ... -

Do dividends signal more earnings?
2004-02-01Signaling models have contributed to the corporate finance literature by formalizing 'the informational content of dividends' hypothesis. However, these models are under criticism of empirical literature, as weak evidences ... -

A general lagrangian approach for non-concave moral hazard problems
2000-07-01We establish a general Lagrangian for the moral hazard problem which generalizes the well known first order approach (FOA). It requires that besides the multiplier of the first order condition, there exist multipliers for ...
