In this work, we present a method for signal-to-noise ratio maximization using a linear filter based on minor component analysis of the noise covariance matrix. As we will see, the greatest benefits are obtained when both ...

We study optimal allocations in an environment in which money is essential due to lack of commitment and anonymity of individuals. Because the economy features aggregate preference shocks, we apply a notion of implementability ...

This paper proposes a simple alternative for the treatment e ect estimators based on match- ing on the estimated propensity score. In this approach, both weights and the number of coun- terfactuals employed in realizing ...

In the wake of the Cold War, democracy has gained the status of a mantra. Yet there is no consensus about how to conceptualize and measure regimes such that meaningful comparisons can be made through time and across ...

In this paper, we consider the propagation of water waves in a long-wave asymptotic regime, when the bottom topography is periodic on a short length scale. We perform a multiscale asymptotic analysis of the full potential ...

El propósito del trabajo es presentar un procedimiento de segmentación aglomerativo jerárquico que en determinadas condiciones permite reducir sustancialmente la dimensión de las matrices de distancia que se utilizan para ...
