Absenteeism among manual workers is, without doubt, one of the most significant factors to affect the functioning of assembly lines in developed markets. That high levels of absenteeism have negative repercussions on the quality and costs of operations is a widely held view. According to the...

In this paper we build a model of a dollarized economy with imperfect financial markets to analyze and qualify the common view that countries with higher dollarization exhibit higher pass-through. We show that the classic inflationary effects of a real depreciation -higher internal demand and...

We introduce a general binomial model for asset prices based on the concept of random maps. The asymptotic stationary distribution for such model is studied using techniques from dynamical systems. In particular, we present a technique to construct a general binomial model with a predetermined...

The stabilization effects of Taylor rules are analyzed in a limited participation framework with and without credit market imperfections in capital goods production. Financial frictions substantially amplify the impact of shocks, and also reinforce the stabilizing or destabilizing effects of...

This paper proposes a mechanism that can be operated without money in situations where agents have to decide over some common projects when they are not informed about others' preferences. The success of the mechanisms proposed in the literature to deal with similar problems usually relies on...

A new insurance provider or a regulatory agency may be interested in determining a risk measure consistent with observed market prices of a collection of risks. Using a relationship between distorted coherent risk measures and spectral risk measures, we provide a method for reconstruction...

The interpretation of the Fama and French (1993) SMB and HML factors as risk factors is an open question that has carried a lot of controversy in the asset pricing literature and it is far from being solved. The aim of this study is to contribute to the understanding of this issue by analyzing a...

This paper analyzes the impact of the exchange rate volatility on the performance of the Peruvian economy using financial information from 163 non-financial listed firms. We find evidence that, for firms holding dollar-denominated debt, investment decisions are negatively affected by real...

A new automatic method based on the wavelet and Hilbert transforms for measuring the motor unit action potential (MUAP) duration is presented in this work. A total of 182 MUAPs from two different muscles were analysed. The average MUAP waveform was wavelet-transfomed, and a particular scale of...

A semiparametric bivariate fractionally cointegrated system is considered, integration orders possibly being unknown and I(0) unobservable inputs having nonparametric spectral density. Two kinds of estimate of the cointegrating parameter ν are considered, one involving inverse spectral...
