The petroleum industry operates under great uncertainty. Achieving an efficient approach to quantify uncertainty in oil production models is of key importance supporting decision-makers find suitable strategies for mitigating risks and maximizing profit. Uncertainty quantification commonly performed based on the Monte Carlo this a very time-consuming process by using physics-based developed res...

We study the impact of international migration on enrollment of the left-behinds in Albania using the 2008 and 2012 Living Standard Measurement Survey. We employ a 2-stage Probit model controlling for endogeneity with an instrumental-variable approach. We find that migration has a negative and significant impact on enrollment in both waves. This result holds across different sub-samples and alt...

Critical Periods During Childhood and Adolescence: A Study of Adult Height Among Immigrant Siblings We identify the ages that constitute critical periods in children’s development towards their adult health status. For this we use data on families migrating into Sweden from countries that are mostly poorer, with less healthy conditions. Long-run health is proxied by adult height. The relation b...

In this article, we propose a new estimation strategy that draws on the variation in the performance between the male and the female national soccer team within a country to identify the effect of gender equality on women’s soccer success. For this, countryyear fixed effects are used to control for both time-constant and time-variant countryspecific factors. Our results reveal that within-count...

The time-averaged shear-wave velocity in the upper 30 m of ground, VS30, is a key soil descriptor for estimating site response despite its recognized limitations. It employed both, site-specific probabilistic hazard assessments (PSHAs) and regional seismic codes. This work presents model VS30 Iberian Peninsula as function three proxies: topographic slope, geological age lithology at each site. ...

This paper uses S&P 500 index options data to examine whether proxies of investor sentiment, or aggregate errors in investor beliefs, affect option prices and asset pricing kernel. I find that when market sentiment becomes more bearish (resp. bullish), both index option smile and asset pricing kernel are more (resp. less) negatively sloped. These relations are statistically and economically sig...

Interoperability is an important issue, especially in Grid infrastructures that use multiple, inhomogeneous Grid middlewares. Monitoring such heterogeneous scenarios requires interoperability of different information services. The approach taken bases on an integration proxy together with a standardized information model. This proxy functions as a bridge between the information models used in d...

We develop and estimate an econometric model of limit-order execution times using survival analysis and actual limit-order data. We estimate versions for time-to-first-fill and time-to-completion for both buy and sell limit orders, and incorporate the effects of explanatory variables such as the limit price, limit size, bid/offer spread, and market volatility. Execution times are very sensitive...
