Nucleus accumbens activation mediates the influence of reward cues on financial risk-taking

Knutson, Brian; Wimmer, G. Elliott; Kuhnen, Camelia; … - Volkswirtschaftliche Fakultät, … - 2008

In functional magnetic resonance imaging (FMRI) research, nucleus accumbens (NAcc) activation spontaneously increases … prior to financial risk taking. Since anticipation of diverse rewards can increase NAcc activation, even incidental reward … cues may influence financial risk-taking. Using event-related FMRI, we predicted and found that anticipation of viewing …

Linear regression using both temporally aggregated and temporally disaggregated data: Revisited

Qian, Hang - Volkswirtschaftliche Fakultät, … - 2010

This paper discusses regression models with aggregated covariate data. Reparameterized likelihood function is found to be separable when one endogenous variable corresponds to one instrument. In that case, the full-information maximum likelihood estimator has an analytic form, and thus...

Efficient Bayesian estimation and combination of GARCH-type models

Ardia, David; Hoogerheide, Lennart F. - Volkswirtschaftliche Fakultät, … - 2010

This chapter proposes an up-to-date review of estimation strategies available for the Bayesian inference of GARCH-type models. The emphasis is put on a novel efficient procedure named AdMitIS. The methodology automatically constructs a mixture of Student-t distributions as an approximation to...

Forecasting economy with Bayesian autoregressive distributed lag model: choosing optimal prior in economic downturn

Bušs, Ginters - Volkswirtschaftliche Fakultät, … - 2009

Bayesian inference requires an analyst to set priors. Setting the right prior is crucial for precise forecasts. This paper analyzes how optimal prior changes when an economy is hit by a recession. For this task, an autoregressive distributed lag (ADL) model is chosen. The results show that a...

Assessing the Impacts of Non-Ricardian Households in an Estimated New Keynesian DSGE Model

Marto, Ricardo - Volkswirtschaftliche Fakultät, … - 2013

Using Bayesian maximum likelihood and data for Portugal, I estimate a New Keynesian DSGE model allowing for the presence of non-Ricardian households and test the stability of the model's prediction when the fraction of liquidity-constrained households changes. In particular, I assess the impacts...

Posterior consistency of nonparametric conditional moment restricted models

Liao, Yuan; Jiang, Wenxin - Volkswirtschaftliche Fakultät, … - 2011

This paper addresses the estimation of the nonparametric conditional moment restricted model that involves an infinite-dimensional parameter g0. We estimate it in a quasi-Bayesian way, based on the limited information likelihood, and investigate the impact of three types of priors on the...
