Following a five-year period during which economic and social performance in Latin America and the Caribbean surpassed anything seen in recent decades, the global economic and financial crisis not only hurt macroeconomic variables but also impacted heavily on labour markets in the region’s countries. Between 2003 and 2008 employment rates had risen considerably, especially in the formal sector, but the crisis spelled a reversal of this trend. Nevertheless, the region was better prepared than it had been in previous crises, since it had achieved a sound fiscal footing, a good level of international reserves and low rates of inflation. This meant that the authorities had the space to implement countercyclical policies on both fiscal and monetary levels. Be this as it may, faced with the worst global crisis since the Great Depression of the 1930s, these measures could only attenuate the impact on the region’s economies —they could not prevent it altogether. Furthermore, the crisis struck with notable differences among subregions and countries depending on the nature of their trade integration, and not all the countries had the fiscal space to implement vigorous countercyclical policies. As discussed in this third ECLAC/ILO bulletin, the crisis did less damage to the region’s labour markets than had been feared at the beginning of last year, thanks to the implementation of public policies geared towards employment, as reviewed in the two previous bulletins. This bulletin offers an additional analysis from the perspective of gender equality. Moreover, some countries in the region, notably Brazil, managed to rapidly stabilize and revive economic growth, with positive effects on labour variables. The fact remains, however, that millions in Latin America and the Caribbean lost their jobs or were obliged to accept more poorly paid employment in more precarious conditions. The macroeconomic data indicate that recovery is under way and is stronger and occurring more rapidly than foreseen one year ago. In fact, regional growth in 2010 may well exceed the 4.1% forecast at the end of 2009. Consequently, although the unemployment rate may be expected to record a modest drop, it may not return to pre-crisis levels. The upturn is taking many different forms in the countries of the region. In some, especially in South America, recovery has benefited from the buoyancy of the Asian economies, whose demand for natural resources has driven large increases in exports, in terms of both volume and price. Countries whose economies are closely tied to the United States economy are benefiting from the recovery there, albeit more slowly and with a certain lag. Conversely, some countries are still suffering from major disequilibria, which are hampering their economic reactivation. Lastly, Chile and Haiti were both victims of devastating earthquakes early in the year and are therefore facing additional challenges associated with reconstruction, on top of their efforts to sustain an economic upturn. Despite the relatively favourable outlook for regional growth in 2010, great uncertainty still surrounds the global economy’s recovery, which affects the region’s economic prospects over the longer term. The weakness of the recovery in some regions and the doubts about its sustainability in others, as well as shocks that have occurred in international financial markets, are warning signs which authorities need to monitor continuously because of the region’s close integration with the global economy. In addition, a return to growth does not directly or automatically mean higher employment rates —still less decent working conditions. Although some labour indicators have performed reasonably favourably since the end of last year, the countries still face daunting challenges in improving the labour market integration of millions in Latin America and the Caribbean who are not seeing the fruits of renewed growth. This is why it is important to learn the lessons arising from the policies implemented during the crisis to offset its impact on labour markets. With this third joint bulletin, ECLAC and ILO continue to pursue their objective of affording the region the information and analyses needed to face these challenges, as regards both trends in the region’s labour markets and the corresponding policy options.

Since the financial and economic crisis began to affect the real economy and spread throughout the world, the region’s economies have been faced with a situation where data on employment and labour reflect the real stories of millions of women and men for whom the future has become uncertain. When these problems began to appear, the International Labour Organization (ILO) warned that the world faced a global employment crisis whose consequences could lead to a social recession. As the Economic Commission for Latin America and the Caribbean (ECLAC) has pointed out, the outbreak of the crisis put an end to a five-year period of sustained growth and falling unemployment. As early as the second half of 2008, the figures began to reflect slowing economic growth, while a downward slide began in the labour market. This initial bulletin, produced jointly by ECLAC and ILO, seeks to review the ways in which the crisis is affecting the region’s labour markets. Amidst a situation characterized by shocks and uncertainty, governments and social partners must have the inputs needed for designing public policies to increase the population’s levels of employment and well-being. It is planned to produce two further bulletins by January 2010, in order to measure the impact of the crisis on employment and provide an input to the process of defining the best public policies to reverse its consequences. The bulletin reviews the most recent available indicators and analyses them in order to establish trends and detect variations. It provides statistics for the first quarter, estimates for the rest of 2009, and a review of policies announced by the Governments. In 2008, the last year of the growth cycle, the region’s urban unemployment stood at 7.5%. According to economic growth forecasts for 2009, the average annual urban unemployment rate for the region will increase to between 8.7% and 9.1%; in other words, between 2.8 million and 3.9 million additional people will swell the ranks of the unemployed. Data for the first quarter of 2009 already confirm that the crisis is hitting employment in the region. Compared with the first quarter of 2008, the urban unemployment rate was up by 0.6 percentage points, representing over a million people.Work will continue until September 2009 on the preparation of a new report on the employment situation, using data updated to the first half of 2009. This will provide a picture of the region’s employment situation, so that growth and employment projections can be adjusted for 2009 as a whole. Strategies for dealing with the crisis must have jobs and income protection as their central goals. Policies are moving in that direction in Latin America and the Caribbean and, if they are effective, an even greater worsening of the situation may be avoided. Labour produces wealth, generates consumption, keeps economies functioning and is a key factor in seeking out the way to more sustainable and equitable growth once the crisis is past.

The Caribbean region remains highly vulnerable to the impacts of climate change. In order to assess the social and economic consequences of climate change for the region, the Economic Commission for Latin America and the Caribbean( ECLAC) has developed a model for this purpose. The model is referred to as the Climate Impact Assessment Model (ECLAC-CIAM) and is a tool that can simultaneously assess multiple sectoral climate impacts specific to the Caribbean as a whole and for individual countries. To achieve this goal, an Integrated Assessment Model (IAM) with a Computable General Equilibrium Core was developed comprising of three modules to be executed sequentially. The first of these modules defines the type and magnitude of economic shocks on the basis of a climate change scenario, the second module is a global Computable General Equilibrium model with a special regional and industrial classification and the third module processes the output of the CGE model to get more disaggregated results. The model has the potential to produce several economic estimates but the current default results include percentage change in real national income for individual Caribbean states which provides a simple measure of welfare impacts. With some modifications, the model can also be used to consider the effects of single sectoral shocks such as (Land, Labour, Capital and Tourism) on the percentage change in real national income. Ultimately, the model is envisioned as an evolving tool for assessing the impact of climate change in the Caribbean and as a guide to policy responses with respect to adaptation strategies.

The current energy systems within Curaçao depend primarily on high cost, imported fossil fuels, and typically constitute power sectors that are characterized by small, inefficient generation plants which result in high energy prices. As a consequence of its dependence on external fuel supplies, Curaçao is extremely vulnerable to international oil price shocks, which can impact on economic planning and foreign direct investment within their industrial sectors. The ability of the successive governments to source capital for economic stimulation and social investment is therefore significantly challenging. Additionally, there is over-dependence on two of the most climate-sensitive economic sectors, namely the tourism and fisheries sectors, but the vulnerabilities of the country to the effects of climate change make adaptation difficult and costly. It is within this context that this report focuses on identification of the fiscal and regulatory barriers to implementation of energy efficiency and renewable energy technologies in Curaçao with a view of making recommendations for removal of these barriers. Consultations with key Government officials, the private sector as well as civil society were conducted to obtain information and data on the energy sector in the country. Desktop research was also conducted to supplement the information gathered from the consultations. The major result of the assessment is that Curaçao is at an early stage in the definition of its energy sector. Despite some infrastructural legacies of the pre-independence era, as well as a number of recent developments including the modernization and expansion of its windfarms and completion of a modern Electricity Policy, there are still a number of important institutional and policy gaps within the energy sector in Curaçao. The most significant deficiency is the absence of a ministry or Government agency with portfolio responsibility for the energy sector as a whole; this has: limited the degree to which the activities of energy sector stakeholders are coordinated and retarded the development and implementation of a comprehensive national energy policy. The absence of an energy policy, which provides the framework for energy planning, increases investor risk. Also, the lack of political continuity that has emanated from the frequent changes in Government administrations is a concern among stakeholders and has served to reduce investor confidence in particular, and market confidence in general.

Caribbean Small Island Developing States are considered to be particularly vulnerable to external shocks that stem from changes in climate and the increase in frequency and magnitude of natural disasters. Quantification of the extent of vulnerability of these islands may be measured by the use of several indices including the Economic Vulnerability Index (EcVI), the Disaster Deficit Index (DDI), the Environmental Vulnerability Index (EVI) and the Social Vulnerability Index (SVI). The capacity to build resilience may be measured by the Economic Resilience Index (ERI). Of importance in the measurement of vulnerability and resilience is the impact on women and children. In order to reduce vulnerability and promote resilience, Caribbean SIDS are urged to develop adaptation strategies. Such strategies include the conduct of indepth studies on natural environmental impacts specifically in terms of biophysical and socio economic impacts. It is also necessary to review best practices in terms of preparedness, resilience building and climate change adaptation in other countries such as Cuba. Addressing vulnerability and building resilience requires appropriate information and data and priority should be given to addressing data gaps. It would also be expedient to classify vulnerability and resilience as regional public goods wherein one country’s benefit does not compromise another country’s ability to benefit. Finally, it is important to acknowledge that vulnerability is, in part, is a function of gender so that indicators need to be disaggregated to reflect the country-specific gendered socioeconomic situation.

The purpose of the expert group meeting was to bring together modelling practitioners to share experiences and to reflect on how to overcome new and old challenges to model building in the Caribbean. As part of the rationale for such a meeting, it was argued that since a major objective of policymaking in the Caribbean was to create the conditions for growth with equity while reducing vulnerability to economic and environmental shocks, model builders must develop strategies to properly address those questions in a unified way. It was further suggested that those goals, though straightforward, required a concentrated technical effort to clarify and update understanding of the workings of Caribbean economies. The emphasis on addressing issues of growth, equity and vulnerability was urgent because Caribbean economies were at a crossroads, with major challenges to the foundations and premises on which the economies had been built.

Caribbean Small Island Developing States (SIDS), by their very nature, are vulnerable to external shocks. Research shows that the Caribbean subregion experienced 165 natural disasters between 1990 and 2008 and the total impact of natural disasters on the subregion was estimated at US$136 billion. The impact on the social sectors was estimated at US$57 billion, or 42% of the total effect. As small open economies, the Caribbean SIDS are also vulnerable to the vagaries of the international economic system and have experienced declines in tourism, merchandise exports receipts, remittances and capital flows throughout the financial crisis. The negative impact of natural hazards exacerbates the capacity of Caribbean SIDS to overcome the development challenges, such as those posed by the current global economic and financial crisis. Disaster risk reduction (DRR), therefore, is of critical concern to subregional governments and their people. For the purpose of this study, six Caribbean SIDS were selected for detailed analyses on the macro socio-economic impact of extreme events to the education sector. They are the Cayman Islands, Grenada, Guyana, Haiti, Jamaica, and Montserrat. This paper proposes that better integration of DRR in the education sector cannot be easily achieved if policymakers do not recognize the social nature of risk perception and acceptance in Caribbean SIDS, which necessitates that risk reduction be treated as a negotiated process which engages all stakeholders.

Se propone un modelo de equilibrio general estructural para analizar las reacciones del tipo de cambio nominal y el nivel de precios internos ante tres tipos de shocks externos en economías emergentes con acceso limitado a los mercados mundiales de capital. Aunque los resultados dependen decisivamente del tipo de shock externo, los parámetros del balance nacional aquí examinados, la prima de riesgo y el índice de endeudamiento externo exacerban las reacciones de las dos variables endógenas, sin alterar el grado de traspaso del tipo de cambio. Además, las curvas de Phillips más planas, como las observadas actualmente en muchas economías, tienden a aumentar el traspaso del tipo de cambio. A partir de estos resultados se recomienda a las autoridades de las economías emergentes, que desean estabilizar los mercados y limitar el traspaso del tipo de cambio, minimizar los dos parámetros de riesgo mediante un régimen de metas de inflación flexible.

Nicaragua is making progress towards the Millennium Development Goals, but is set to miss a number of targets in 2015. This paper’s general equilibrium analysis shows that it is unfeasible for the government to step up spending in order to meet these targets by the 2015 deadline. Any boost to public spending and financing would have to be front-loaded, which would entail pernicious macroeconomic trade-offs. A more realistic scenario would be to postpone meeting the goals until 2020. In that case, the allocation of public spending would spur economic growth without causing macroeconomic hardships, although the country would nevertheless remain highly vulnerable to external shocks.

This paper analyses three aspects of the share market operated by the Lima Stock Exchange: (i) the short-term relationship between the pricing, direction and volume of order flows; (ii) the components of the spread and the equilibrium point of the limit order book per share, and (iii) the pricing, order direction and trading volume dynamic resulting from shocks in the same variables when lagged. The econometric results for intraday data from 2012 show that the short-run dynamic of the most and least liquid shares in the General Index of the Lima Stock Exchange is explained by the direction of order flow, whose price impact is temporary in both cases.

Las estadísticas oficiales y los indicadores clave son fundamentales para observar el progreso económico y social de los países, determinar los impulsores estructurales de su crecimiento y establecer prioridades. Mediante la metodología de Khramov y Lee (2013) e indicadores clave provenientes del Sistema de Cuentas Nacionales (scn), las estadísticas de la balanza de pagos, las monetarias y financieras y las concernientes a las finanzas públicas, se propone utilizar un indicador compuesto para evaluar el desempeño económico de América Latina. A largo plazo se encuentra que, en general, ese índice registra los grandes shocks económicos y los períodos de sólido desempeño del período 1990-2013. Su construcción permite medir los indicadores específicos que determinan el comportamiento económico general. Aunque el índice resulta muy útil para analizar la dinámica macroeconómica en comparación con valores de referencia alternativos, es necesario ser precavidos al seleccionar un período para estimar el peso relativo de cada componente.

En este trabajo se reúnen los aportes de diferentes escuelas de pensamiento para construir un modelo que permita representar la dinámica macroeconómica de los países latinoamericanos. Para ello se parte de la estructura provista por los modelos stock-flujo consistentes de la tradición post keynesiana, a la cual se incorpora una matriz insumo producto y una serie de aportes de naturaleza estructuralista. Una vez construido el modelo, se introducen las modificaciones necesarias para describir cuatro tipos de estructuras productivas presentes en la región: países agroindustriales, petroleros, mineros y maquiladores. Luego, se simulan una serie de shocks a fin de evaluar el impacto diferencial de los mismos sobre el crecimiento, la distribución del ingreso y la sustentabilidad externa, bajo la sospecha de que la estructura productiva determina en gran parte la vulnerabilidad de cada país frente a los eventuales shocks a los que se exponen en un mundo globalizado. En función de los resultados hallados, se pueden pensar mecanismos que contribuyan a mitigar el impacto de los shocks o en estrategias que promuevan el cambio estructural.
