Spatiotemporal dynamics are introduced in a standard Ramsey model of optimal growth in which capital moves toward locations where the marginal productivity of capital is relatively higher. We extend Pontryagin s maximum principle to account for transition dynamics governed by a nonlinear partial...

In this paper, we first provide a framework for history-dependent utility models. We further consider discrete infinite horizon dynamic optimization programs in which the instantaneous payoff presents such historydependence. Habits are a particular case of history-dependence. An issue about...

We show that internationally diversified portfolios carry sizeable political risk premia. We use a tail-risk portfolio selection model to obtain political efficient frontiers from skewed return distributions and manage political risk, and design an inference test to draw conclusions. We find...

Environmental, social, and governance (ESG) scores measure companies’ activities concerning sustainability and are organized on three pillars: Environmental (E-), Social (S-), and Governance (G-). Different approaches have been proposed to compute ESG scores for companies, which rely on the...

We consider a dynamic Stackelberg game between a manufacturer and a retailer facing a randomly changing market environment over time modeled as a Markov process. The manufacturer announces the wholesale price and a cooperative (co-op) advertising subsidy, and the retailer sets the retail price...

We propose an efficient procedure to solve for policy counterfactuals in linear models with occasionally binding constraints. The procedure does not require knowledge of the structural or reduced-form equations of the model, its state variables, or its shock processes. Forecasts of the variables...

The purpose of this paper is to introduce the Gerber statistic, a robust co-movement measure for covariance matrix estimation for the purpose of portfolio construction. The Gerber statistic extends Kendall's Tau by counting the proportion of simultaneous co-movements in series when their...

This paper presents a stylized model of interaction among boundedly rational heterogeneousagents in a multi-asset financial market to examine how agents' impatience, extrapolation, andswitching behaviours can affect cross-section market stability. Besides extrapolation and performance based...

We consider some particular cases of the general problem which consists of stating if a shift vector of m elements corresponds to a permutation of the same number of objects. Shifts are defined as the steps each element in a given permutation must perform in order to reach its natural position,...

This paper examines whether monetary indicators are useful in implementing optimal discretionary monetary policy when the policy maker has incomplete information about the environment. We find that money does not contain useful information for the policy maker, if we calibrate the model to the...
