Growth, Employment, and Poverty in Latin America

Guillermo Cruces; Gary S. Fields; David Jaume; Mariana Viollaz

This book examines the links between economic growth, changing employment conditions, and the reduction of poverty in Latin America in the 2000s. Our analysis answers the following broad questions: Has economic growth resulted in gains in standards of living and reductions in poverty via improved labour market conditions in Latin America in the 2000s, and have these improvements halted or been reversed since the international crisis of 2008? How do the rate and character of economic growth, changes in the various employment and earnings indicators, and changes in poverty and inequality indicators relate to each other? Our contribution is an in-depth study of the multi-pronged growth-employment-poverty nexus based on a large number of labour market indicators (twelve employment and earnings indicators and four poverty and inequality indicators) for a large number of Latin American countries (sixteen of them). The book presents a positive and hopeful set of findings for the period 2000 to 2012/13. Economic growth took place and brought about improvements in almost all labour market indicators and consequent reductions in poverty rates. But not all improvements were equal in size or caused by the same things. Some macroeconomic factors were associated with changes in labour market conditions, some of them always in the welfare-improving direction and some others always in the welfare-reducing direction. Most countries in the region suffered a deterioration in at least some labour market indicators as a consequence of the international crisis of 2008, but the negative effects were reversed very quickly in most countries.

ICT adoption in micro and small firms: Can internet access improve labour productivity?

Mariana Viollaz

The rapid spread of information and communication technologies may increase firms’ productivity with important consequences for job creation and for economic growth. This article contributes to this discussion by analysing the impact of internet adoption on labour productivity and the mechanisms shaping this relationship in Peruvian micro and small manufacturing firms over the period 2011-2013. The article estimates a reduced form where labour productivity is a function of internet adoption and other explanatory factors. Internet adoption is instrumented using a measure of the availability of financial opportunities for micro and small firms in Peru. Findings indicate that internet adoption: (i) increases firms’ labour productivity; (ii) reallocates employment away from temporary administrative workers and non-remunerated workers and expands employment of permanent production workers; (iii) leads to the formalization of labour relationships, to the implementation of new organizational practices, and to the improvement of training measures. While changes in employment and formalization of workers are linked to labour productivity gains, increases in training measures and organizational changes do not generate any additional productivity increase.
