Economic survey of the Caribbean 2014: Reduced downside risks and better prospects for a recovery

The current survey provides an overview of the economic performance for 2013 of the Bahamas, Barbados, Belize, Guyana, Jamaica, Suriname, Trinidad and Tobago plus the eight member states of the Eastern Caribbean Currency Union (ECCU) and the outlook for 2014 and 2015. Data were collected from a review of reports from national governments and through interviews with government officials in each of the countries analyzed.

The employment situation in Latin America and the Caribbean: Countercyclical policies for a sustained recovery in employment

Latin America and the Caribbean experienced an unexpectedly vigorous economic recovery in 2010 after the output contraction of 2009. This upturn was reflected in the region’s employment and unemployment rates, which resumed the positive trends that had been broken by the crisis, and formal wages rose slightly. The strength of the recovery and labour-market performance varied markedly across subregions and countries, however. The first part of this joint ECLAC/ILO publication on the employment situation in Latin America and the Caribbean looks at how labour markets have responded to the rapid economic upswing in 2010 and early 2011, highlighting both the significant advances achieved in the post-crisis period and the sharp differences evident across subregions and countries. As well as tapping into the improved external conditions which followed upon the Asianled global economic upturn, several Latin American countries were also able to contain the impacts of the crisis and underpin their own recovery with countercyclical policies, thanks to the leeway gained by their macroeconomic management during the run of growth from 2003 to 2008. These countries were in a position to implement expansionary fiscal and monetary policies, some of which channelled higher fiscal spending through labour-market policies or softened the impact of the crisis on employment and income, as discussed in previous ECLAC/ILO bulletins. Since the region is fairly new to the use of countercyclical policies, the second part of this document reviews the experiences arising from those policies and considers lessons for institutionalizing them. Economic growth in the Latin American and Caribbean region has historically been marked by the volatility of its economic cycles, with high-growth periods being succeeded by deep crises. Volatility has conspired against the use of production resources over extended periods and short growth horizons have impeded investment in capital and labour. In the recent international crisis, the deployment of countercyclical macroeconomic policy helped to reduce the depth and duration of the impact and to leverage a more rapid recovery. It is therefore worth looking at the fundamentals of a long-term countercyclical macroeconomic policy which would provide the tools needed to deal with future crises and pave the way for economic growth that may be sustained over time. A special factor during this crisis was that a greater effort was made to support employment and income. Several of the labour-market policy measures taken acted as vehicles for conveying increased fiscal spending to individuals, reflecting greater consideration for equality concerns. Indeed, these measures were aimed not only at stabilizing andstrengthening domestic demand per se, but also at preventing the crisis from hitting lowest-income households the hardest, as had occurred in previous episodes. And —again unlike the pattern seen in previous episodes— inflation actually fell during the crisis as the high food and fuel prices seen in the run-up to it eased as a result of both existing macroeconomic policies and global conditions. This averted the surge in inequality so often seen in previous crises. Two caveats must be added, however. First, not all the countries were in a position to deploy strong countercyclical policies. Many simply lacked the fiscal space to do so. Second, some countries took this sort of measure more as an ad hoc response to the crisis than as part of a clearly established countercyclical policy strategy. The challenge, then, is to institutionalize a countercyclical approach throughout the economic cycle. Taking up this challenge is part of making economic growth more sustainable. This year —2011— was ushered in by rapid economic growth and substantial improvements in labour indicators. With the region’s GDP projected to grow well over 4% this year, ECLAC and ILO estimate that the regional unemployment rate will fall substantially again, from 7.3% in 2010 to between 6.7% and 7.0% in 2011.

The employment situation in Latin America and the Caribbean: Recovery of employment: towards a sustainable model

The adverse effects on Latin America and the Caribbean of the global economic and financial crisis, the worst since the 1930s, have been considerably less than was once feared. Although a run of growth was cut short in 2009 and regional output shrank by 1.9%, the impact of the crisis was limited by the application of countercyclical fiscal and monetary policies by many of the region’s governments. The recovery in the economies, particularly in South America, has gone hand-in-hand with the rapid resurgence of the emerging economies of Asia, with all the favourable consequences this has had for global trade. A similar pattern may be observed regarding the impact of the crisis on labour markets in Latin America and the Caribbean. Although millions of people lost their jobs or had to trade down to lower-quality work, levels of employment (including formal employment) fell by less than originally foreseen. At the same time, real wages rose slightly in a context of falling inflation. The labour market thus stabilized domestic demand, and this contributed to the recovery that began in many countries in late 2009. Improved international trade and financing conditions, and the pick-up in domestic demand driven by macroeconomic policies, have led different commentators to estimate growth in the region’s economy at some 6% in 2010. As detailed in the first part of this edition of the Bulletin, the upturn has been manifested at the regional level by the creation of formal employment, a rise in the employment rate, a decline in joblessness and a moderate increase in real wages. Specifically, it is estimatedthat the regional unemployment rate will have dropped by 0.6 percentage points, from 8.1% in 2009 to 7.5% in 2010. The performance of different countries and subregions has been very uneven, however. On the one hand, there is Brazil, where high economic growth has been accompanied by vigorous creation of formal jobs and the unemployment rate has dropped to levels not seen in a long time. Other countries in South America have benefited from strong demand for natural resources from the Asian countries. Combined with higher domestic demand, this has raised their economic growth rates and had a positive impact on employment indicators. On the other hand, the recovery is still very weak in certain countries and subregions, particularly in the Caribbean, with employment indicators continuing to worsen.Thus, the recovery in the region’s economy in 2010 may be characterized as dynamic but uneven. Growth estimates for 2011 are less favourable. The risks associated with the imbalances in the world economy and the withdrawal of countercyclical fiscal packages are likely to cause the region to grow more slowly in 2011. Accordingly, a small further reduction of between 0.2 and 0.4 percentage points in the unemployment rate is projected for 2011. However, these indicators of recovery do not guarantee growth with decent work in the long term. To bolster the improvement in labour market indicators and generate more productive employment and decent work, the region’s countries need to strengthen their macroeconomic policies, improve regional and global policy coordination, identify and remove bottlenecks in the labour market itself and enhance instruments designed to promote greater equality. Like the rest of the world, the Latin American and Caribbean region is also confronted with the challenge of transforming the way it produces so that its economies can develop along tracks that are sustainable in the long term. Climate change and the consequent challenge of developing and strengthening low-carbon production and consumption patterns will also affect the way people work. A great challenge ahead is to create green jobs that combine decent work with environmentally sustainable production patterns. From this perspective, the second part of this Bulletin discusses the green jobs approach, offering some information on the challenges and opportunities involved in moving towards a sustainable economy in the region and presenting a set of options for addressing environmental issues and the repercussions of climate change in the world of work. Although the debate about the green jobs concept is fairly new in the region, examples already exist and a number of countries have moved ahead with the application of policies and programmes in this area. Costa Rica has formulated a National Climate Change Strategy, for example, whose foremost achievements include professional training in natural-resource management. In Brazil, fuel production from biomass has increased and social housing with solar panelling is being built. A number of other countries in the region are making progress in areas such as ecotourism, sustainable agriculture and infrastructure for climate change adaptation, and in formalizing the work of people who recycle household waste. The shift towards a more environmentally sustainable economy may cause jobs to be destroyed in some economic sectors and created in others. The working world will inevitably undergo major changes. If the issue is approached by way of social dialogue and appropriate public policies, there is a chance to use this shift to create more decent jobs, thereby contributing to growth in the economy, the construction of higher levels of equality and protection for the environment.

Enriched environment contributes to recovery of visual acuity and increases perineuronal nets in monocular-deprived animals

ABSTRACT The aim of the present study was to analyze the influence of enriched environment on the distribution of perineuronal nets (PNNs) using a stereogically based unbiased protocol and visual acuity in adult Swiss albino mice that underwent monocular deprivation during the critical period of postnatal development. Eight female Swiss albino mice were monocular deprived were removed and cut at 70 µm thickness in a vibratome and processed for lectin histochemical staining with Wisteria floribunda agglutinin (WFA). Architectonic limits of area 17 were conspicuously defined by WFA histochemical staining, and the optical fractionator stereological method was applied to estimate the total number of PNNs in the supragranular, granular, and infragranular layers. All groups were compared using Student's t-test at a 95% confidence level. Comparative analysis of the average PNN estimations revealed that the EE group had higher PNNs in the supragranular layer (2726.33 ± 405.416, mean ± standard deviation) compared with the SE group (1543.535 ± 260.686; Student's t-test, p = .0495). No differences were found in the other layers. Visual acuity was significantly lower in the SE group (0.55 cycles/degree) than in the EE group (1.06 cycles/degree). Our results suggest that the integrity of the specialized extracellular matrix PNNs of the supragranular layer may be essential for normal visual acuity development.

Progressive recovery of a tropical deforested stream community after a flash flood

AIM: In this study, we evaluated and compared community attributes from a tropical deforested stream, located in a pasture area, in a period before (PRED I) and three times after (POSD I, II, and III) a flash flood, in order to investigate the existence of temporal modifications in community structure that suggests return to conditions previous to the flash flood. METHODS: Biota samples included algae, macrophytes, macroinvertebrates, and fish assemblages. Changes in stream physical structure we also evaluated. Similarity of the aquatic biota between pre and post-disturbance periods was examined by exploratory ordination, known as Non-Metric Multidimensional Scaling associated with Cluster Analysis, using quantitative and presence/absence Bray-Curtis similarity coefficients. Presence and absence data were used for multivariate correlation analysis (Relate Analysis) in order to investigate taxonomic composition similarity of biota between pre and post-disturbance periods. RESULTS: Our results evidenced channel simplification and an expressive decrease in richness and abundance of all taxa right after the flood, followed by subsequent increases of these parameters in the next three samples, indicating trends towards stream community recovery. Bray-Curtis similarity coefficients evidenced a greater community structure disparity among the period right after the flood and the subsequent ones. Multivariate correlation analysis evidenced a greater correlation between macroinvertebrates and algae/macrophytes, demonstrating the narrow relation between their recolonization dynamics. CONCLUSIONS: Despite overall community structure tended to return to previous conditions, recolonization after the flood was much slower than that reported in literature. Finally, the remarkably high flood impact along with the slow recolonization could be a result of the historical presence of anthropic impacts in the region, such as siltation, riparian forest complete depletion, and habitat simplification, which magnified the effects of a natural disturbance.
