Cash transfer programs have expanded widely in developing countries and have been credited for sizable reductions in poverty. However, their potential disincentive effects on beneficiaries' labor supply have spurred a heated policy debate. This paper studies the impact of a large-scale program Bolsa Familia in Brazil on local labor markets in a context where such concerns could be particularly strong: eligibility is means-tested and the paper focuses on the formal labor market, where earnings are more easily verifiable. Yet, the analysis finds that an expansion of Bolsa Familia increased local formal employment, using variation in the size of the reform across municipalities. The evidence is consistent with multiplier effects of cash transfers in the local economy, which dominate potential negative effects on formal labor supply among beneficiaries.

Does increased import competition lead to higher returns to skill within an industry and, therefore, to greater incentives for skill acquisition? Does it also induce skill upgrading by the industry's existing workforce? To answer these questions, this paper follows individual workers across skills/occupations, firms, and industries using a longitudinal matched employer-employee data set covering all workers and firms in Portugal over 1986-2000. To identify the effects of international competition the analysis uses two exogenous measures of changes in international competition at the industry level. The first is a quasi-natural experiment based on the strong appreciation of the Portuguese currency during 1989-1992 and preexisting differences in trade exposure across industries in a differences-in-differences estimation. The second is source-weighted real exchange rates defined at the industry level. Based on both empirical strategies, and two definitions of skill, the paper shows that international competition increases returns to skill and induces skill/occupation upgrading within industries.

Signal transduction comprises the intracellular biochemical signals which induce the appropriate cell response to an external stimulus. The players in signal transduction are diverse, from small molecules as first messengers, to proteins, receptors, transcription factors, among many others. The different signaling pathways and the crosstalk between them originates the unique signaling profile of every cell type in the human body. The cell signaling specificity depends on several aspects including protein composition, subcellular localization and complexes and gene promoters. This textbook provides a comprehensive overview of the specific signaling pathways on a variety of human tissues. This information can be of great value for health science researchers, professionals and students to understand key pathways for tissue-specific functions in the plethora of signals, signals receptors, transducers and effectors. Chapter 3 and 15 are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

This paper examines the extent to which the destination of exports matters for the input prices paid by firms, using detailed customs and firm-product-level data from Portugal. We use exchange-rate movements as a source of variation in export destinations and find that exporting to richer countries leads firms to charge more for outputs and pay higher prices for inputs, other things equal. The results are supportive of the hypothesis that an exogenous increase in average destination income leads firms to raise the average quality of goods they produce and to purchase higher-quality inputs.
