TL;DR: A theory is proposed that increased age in adulthood is associated with a decrease in the speed with which many processing operations can be executed and that this reduction in speed leads to impairments in cognitive functioning because of what are termed the limited time mechanism and the simultaneity mechanism.
Abstract: A theory is proposed to account for some of the age-related differences reported in measures of Type A or fluid cognition. The central hypothesis in the theory is that increased age in adulthood is associated with a decrease in the speed with which many processing operations can be executed and that this reduction in speed leads to impairments in cognitive functioning because of what are termed the limited time mechanism and the simultaneity mechanism. That is, cognitive performance is degraded when processing is slow because relevant operations cannot be successfully executed (limited time) and because the products of early processing may no longer be available when later processing is complete (simultaneity). Several types of evidence, such as the discovery of considerable shared age-related variance across various measures of speed and large attenuation of the age-related influences on cognitive measures after statistical control of measures of speed, are consistent with this theory.

TL;DR: This article investigated the impact of stock markets and banks on economic growth using a panel data set for the period 1976-98 and applying recent GMM techniques developed for dynamic panels and found that stock markets positively influence economic growth and these findings are not due to potential biases induced by simultaneity, omitted variables or unobserved country-specific effects.
Abstract: This paper investigates the impact of stock markets and banks on economic growth using a panel data set for the period 1976-98 and applying recent GMM techniques developed for dynamic panels. On balance, we find that stock markets and banks positively influence economic growth and these findings are not due to potential biases induced by simultaneity, omitted variables or unobserved country-specific effects.

TL;DR: The authors explore the social theory and consequent methodology that underpins studies of transnational migration and highlight social processes and institutions that are routinely obscured by traditional migration scholarship but that become clear when we use a transnational lens.
Abstract: This article explores the social theory and consequent methodology that underpins studies of transnational migration. First, we propose a social field approach to the study of migration and distinguish between ways of being and ways of belonging in that field. Second, we argue that assimilation and enduring transnational ties are neither incompatible nor binary opposites. Third, we highlight social processes and institutions that are routinely obscured by traditional migration scholarship but that become clear when we use a transnational lens. Finally, we locate our approach to migration research within a larger intellectual project, taken up by scholars of transnational processes in many fields, to rethink and reformulate the concept of society such that it is no longer automatically equated with the boundaries of a single nation-state.

TL;DR: In this paper, the authors use R&D and patent data for European Regions in the 1977-1995 period to estimate the effect of research externalities in generating innovation, and they find that spillovers are very localized and exist only within a distance of 300 km.
