Speaking in numbers : the effect of reading performance on math performance among immigrants
Isphording, Ingo Eduard; Piopiunik, Marc; … - 2015
This paper is the first to estimate a causal effect of immigrant students' reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...

High-ability influencers? : the heterogeneous effects of gifted classmates
Balestra, Simone; Sallin, Aurélien; Wolter, Stefan C. - 2020
This paper examines how exposure to students identified as gifted (IQ ≥ 130) affects achievement in secondary school, enrollment in post-compulsory education, and occupational choices. By using student-level administrative data on achievement combined with psychological examination records, we...

Ambiguity aversion is the exception
Kocher, Martin; Lahno, Amrei Marie; Trautmann, Stefan T. - 2015
An extensive literature has studied ambiguity aversion in economic decision making, and how ambiguity aversion can account for empirically observed violations of expected utility-based theories. Almost all relevant applied models presume a general dislike of ambiguity. In this paper, we provide...

Apportioning of risks via stochastic dominance
Eeckhoudt, Louis R. (contributor);  … - 2008
Consider a simple two-state risk with equal probabilities for the two states. In particular, assume that the random wealth variable Xi dominates Yi via ith-order stochastic dominance for i = M,N. We show that the 50-50 lottery [XN + YM, YN + XM] dominates the lottery [XN + XM, YN + YM] via (N +...

Stay in school or start working? : the human capital investment decision under uncertainty and irreversibility
Bilkic, Natasa; Gries, Thomas; Pilichowski, Margarethe - 2009
As the time of leaving school determines the level of academic achievement this timing decision is central for the human capital investment decision. Real option theory offers a new perspective of the human capital investment decision under uncertainty and irreversibility. Unlike other...

Investing in biogas: timing, technological choice and the value of flexibility from inputs mix
Di Corato, Luca; Moretto, Michele - 2009
In a continuous-time framework we study the technology and investment choice problem of a continuous co-digestion biogas plant dealing with randomly fluctuating relative convenience of input factor costs. Input factors enter into the productive process together mixed according to a given initial...

Booms, recessions and financial turmoil : a fresh look at investment decisions under cyclical uncertainty
Chen, Yu-Fu; Funke, Michael - 2009
The paper studies the interaction between cyclical uncertainty and investment in a stochastic real option framework where demand shifts stochastically between three different states, each with different rates of drift and volatility. In our setting the shifts are governed by a three-state Markov...
