We consider a dynamic multitask principal-agent model in which the agent allocates his resources on two tasks of different types: effort and accident prevention. We explicitly characterize the optimal contract as well as optimal effort and prevention actions applied by the agent. In contrast to...

This paper analyses the main statistical properties of the Emerging Market Bond Index (EMBI), namely long-range dependence or persistence, non-linearities, and structural breaks, in four Latin American countries (Argentina, Brazil, Mexico, Venezuela). For this purpose it uses a fractional...

How can parameter estimates be biased in a dynamic stochastic general equilibrium model that omits nonlinearity in the economy? To answer this question, we simulate data from a fully nonlinear New Keynesian model with the zero lower bound constraint and estimate a linearized version of the...

This paper generalizes the popular stochastic volatility in mean model of Koopman and Hol Uspensky (2002) to allow for time-varying parameters in the conditional mean. The estimation of this extension is nontrival since the volatility appears in both the conditional mean and the conditional...

In a recent paper, a simple index able to evaluate the non-linear bivariate comovement between two asset prices has been proposed. In this paper we assess if that index satisfies the classical seven axioms formulated by Rényi that a measure of dependence should meet. Further, in the cases in...

Using smooth transition regression model analysis, we examine the non-linear predictability of Japanese and US stock market returns by a set of macroeconomic variables between 1981 and 2012. The theoretical basis for investigating non-linear behavior in stock returns can be based on the...

We introduce a non-linear model to study the adjustment of fiscal policy variables in Greece, Ireland, Portugal and Spain over the last 50 years, based on endogenously estimated budget deficit-to-GDP thresholds, which vary with fiscal disequilibria, the economic cycle and financial market...

This study assess the effect of corruption on the occurrence of banking crisis for a sample of 38 countries over the period 2000 – 2017. We consider both the direct and the indirect channels through which corruption might affect the occurrence of banking crisis. We also check using a threshold...
