The Cost of Curiosity: Information-Reward Tradeoffs in Early Childhood
(Elsevier Science Inc, 2026) Lucca, Kelsey; Sen, Hilal H.
Curiosity is a powerful engine of learning that shapes how people explore, acquire knowledge, and adapt to their environments. Though the implications of curiosity are clear, we know little about what drives curiosity. One widely-held view is that satisfying curiosity is intrinsically rewarding. Yet there is limited direct evidence supporting this claim, particularly during early childhood-a period characterized by heightened curiosity. Here, we provide an empirical test of whether satisfying curiosity is intrinsically valuable to children by asking whether they will forego hard-earned rewards to obtain information. To examine the limits of costly curiosity, we ask whether children will give up hard-earned rewards to learn something new, even when the information to be gained is unknown and offers no immediate or long-term benefit. Critically, we test what factors (i.e., age, gender, cultural background, trait curiosity, reward availability) shape children's willingness to engage in costly curiosity. In a sample of 226 children aged 3-6 years in the United States and Turkey, nearly all children (87%) gave up rewards to obtain information. However, costly curiosity was limited, most children gave up only a few rewards (i.e., the smallest amount possible), and the extent of trading varied by gender and culture: boys traded more than girls and children in the United States traded more than in Turkey. These findings provide evidence that children's curiosity is not driven by sheer impulse, but instead, a decision-making process that weighs both costs and benefits, and is shaped by broader individual and cultural factors.

Revisiting Labor Productivity Growth in Turkey: Accounting for Relative Prices, Structural Change, and Sectoral Dynamics
(Cambridge Univ Press, 2026) Taspinar, Zeren Tatar; Atiyas, Izak
This study decomposes aggregate labor productivity growth in Turkey from 1999 to 2023 using a chain-linked gross domestic product (GDP) series with an exactly additive decomposition method. Traditionally, this growth has been decomposed into two components: productivity growth within sectors and labor reallocation across sectors. Using the chain-linked GDP series introduces a third component: changes in relative sectoral prices. Although these relative price changes cancel out at the aggregate level, they influence sectoral contributions to overall labor productivity by altering each sector's weight in total output. Incorporating them, therefore, provides a more comprehensive view of sectoral dynamics by capturing their contributions to aggregate productivity growth. On average, the contribution of structural change slightly exceeds that of the within component. However, both the magnitude and composition of contributions vary considerably across sub-periods. During crisis years, structural change contributed positively while the within-sector component was negative. In contrast, during non-crisis periods, aggregate labor productivity growth declined because the structural-change component weakened persistently and nearly vanished after 2018, despite a positive though limited within-sector component. At the sector level, construction, finance and real estate, community, personal, and government services, and transport and communication largely account for the slowdown, while manufacturing's contribution stayed steady; its composition shifted away from within productivity across periods.
