This study tried to examine EFL translators’ uncertainty and uncertainty management strategies through employing think aloud procedures. The participants of this study were some MA andBA translators selected from several universities in Iran. To this aim, a proficiency test was firstly administered among the volunteers. Then, think aloud protocol and retrospective interview were used to collect...

In this paper we explore the portfolio selection problem involving an uncertain time of eventual exit. To deal with this uncertainty, the worst-case CVaR methodology is adopted in the case where no or only partial information on the exit time is available, and the corresponding problems are integrated into linear programs which can be efficiently solved. Moreover, we present a method for specif...

A robust delay-dependent filtering design is proposed for linear continuous systems with parameter uncertainty and time-varying delay. The resulting filter is of the general linear observer type and it guarantees that the induced -norm of the system, relating the exogenous signals to the estimation error, is less than a prescribed level for all possible parameters that reside in a given polytop...

This paper provides a simulation-based approach to optimal portfolio selection. We take a Bayesian approach as it naturally accounts for estimation risk, i.e., parameter uncertainty, learning of state variables and models, and can incorporate prior beliefs about future return distributions. We specifically highlight two implementations with great potential in portfolio selection. First, for com...

We empirically test separation of ownership and control (SOC) and the interaction of SOC with farmer effort on farm success using data from the U.S. Department of Agriculture’s Agricultural Resource Management Survey. We use a two-stage leastsquares approach with instrumental variables that proxy for participation constraints in binding incentive contracts. We find that the interaction has a si...

Using climate change as a prototype motivating example, this paper analyzes the implications of structural uncertainty for the economics of catastrophes. The paper shows that having an uncertain multiplicative parameter, which ampli…es or scales exogenous impulses and is updated by Bayesian learning, induces a critical “tail fattening”of posterior-predictive distributions. Such fattened tails h...

In this paper we propose an instrumental variables (IV) estimator for a semiparametric outcome model with endogeous discrete treatment variables. The main contribution of our paper is that the identi…cation, consistency and asymptotic normality of our estimator all hold even under misspeci…cation of the treatment model. As expected from Newey and McFadden (1994), the covariance matrix for the p...
