Ravi Bansal and Amir Yaron (2004) developed the Long Run Risk (LRR) model which emphasizes the role of long run risks, that is, low-frequency movements in consumption growth rates and volatility, in accounting for a wide range of asset pricing puzzles. In this article we present a generalized LRR model, which allows us to study the role of cyclical fluctuations and macroeconomic crises on asset...

MASSIMO FRANCHI AND PAOLO PARUOLO PRELIMINARY VERSION Abstract. This paper presents an additive decomposition of the moving average representation of VAR processes into cyclical components. We give a de nition of cyclical component that encompasses seasonal components as well as (stationary) long-run and short-run uctuations. Each cyclical component is univariate and is characterized by a spect...

A recent model studies the evolution of cooperation on a network, and concludes with a result connecting the benefits and costs of interactions and the number of neighbours. Here, an inclusive fitness analysis is conducted of the only case solved analytically, of a cycle, and the identical result is obtained. This brings the result within a biologically familiar framework. It is notable that th...

In the time domain, the observed cyclical behavior of the real wage hides a range of economic in uences that give rise to cycles of di ering lengths and strengths. This may serve to produce a distorted picture of wage cyclicality. Here, we employ and develop frequency domain methods that allow us to assess the relative contribution of cyclical frequency bands on real wage earnings. Earnings are...

A long-standing question in evolutionary biology is how sexual reproduction has persisted in eukaryotic lineages. As cyclical parthenogens, monogonont rotifers are a powerful model for examining this question, yet the molecular nature of sexual reproduction in this lineage is currently understudied. To examine genes involved in meiosis, we generated partial genome assemblies for 2 distantly rel...

In this paper we discuss the properties and algorithmic methods for the identification and classification of cyclical interdependencies in critical infrastructures based on a multigraph model of infrastructure elements with a view to analyze the behavior of interconnected infrastructures under attack. The underlying graph model accommodates distinct types of infrastructures including unbuffered...
