The process of economic development is characterized by substantial reallocations of resources across sectors. In this paper, we construct a multi-sector model in which there are barriers to the movement of labor from low-productivity traditional agriculture to modern sectors. With the barrier in place, we show that improvements in productivity in modern sectors (including agriculture) or reductions in transportation costs may lead to a rise in agricultural employment and through terms-oftrade effects may harm subsistence farmers if the traditional subsistence sector is larger than a critical level. This suggests that policy advice based on the earlier literature needs to be revised. Reducing barriers to mobility (through reductions in the cost of skill acquisition and institutional changes) and improving the productivity of subsistence farmers needs to precede policies designed to increase the productivity of modern sectors or decrease transportation costs.

In the June 2015 issue, the Research Summaries review "Migration: An Attractive Insurance Option in African Countries" (Ahmat Jidoud) and "Investment in Emerging Markets" (Nicolas E. Magud and Sebastian Sosa). The Q&A looks at "Seven Questions on Islamic Finance” (Inutu Lukonga). The Bulletin also includes its regular listings of recent IMF Working Papers and Staff Discussion Notes, as well as information on the "IMF Economic Review." A new IMF eLibrary discussion site on energy and climate change is highlighted, along with new recommendations from IMF Publications.

This study provides a comprehensive overview of Korea’s macroeconomic growth and structural change since World War II, and traces some of the roots of development to the colonial period. The authors explore in detail colonial development, changing national income patterns, relative price shifts, sources of aggregate growth, and sources of sectoral structural change, comparing them with other countries.

The book focuses on Indonesia's most pressing labor market challenges and associated policy options to achieve higher and more inclusive economic growth. The challenges consist of creating jobs for and the skills in a youthful and increasingly better educated workforce, and raising the productivity of less-educated workers to meet the demands of the digital age. The book deals with a range of interrelated topics---the changing supply and demand for labor in relation to the shift of workers out of agriculture; urbanization and the growth of megacities; raising the quality of schooling for new jobs in the digital economy; and labor market policies to improve both labor standards and productivity.

Does what economies export matter for development? If so, can industrial policies improve on the export basket generated by the market? This book approaches these questions from a variety of conceptual and policy viewpoints. Reviewing the theoretical arguments in favor of industrial policies, the authors first ask whether existing indicators allow policy makers to identify growth-promoting sectors with confidence. To this end, they assess, and ultimately cast doubt upon, the reliability of many popular indicators advocated by proponents of industrial policy. Second, and central to their critique, the authors document extraordinary differences in the performance of countries exporting seemingly identical products, be they natural resources or 'high-tech' goods. Further, they argue that globalization has so fragmented the production process that even talking about exported goods as opposed to tasks may be misleading. Reviewing evidence from history and from around the world, the authors conclude that policy makers should focus less on what is produced, and more on how it is produced. They analyze alternative approaches to picking winners but conclude by favoring 'horizontal-ish' policies--for instance, those that build human capital or foment innovation in existing and future products—that only incidentally favor some sectors over others.

Following the so-called "Golden Decade" (2003-2013) of rapid development and strong improvements in social indicators, economic growth has stalled in Latin America and the Caribbean region (LAC). Today, the external environment no longer provides tailwinds to foster an economic rebound. Foreign direct investment has moderated, trade has slowed amid elevated tensions, financing conditions are tightening, and commodity prices are expected to remain flat in the short and medium term. The region therefore needs to find internal sources of growth and focus on a productivity-enhancing reform agenda. The report analyzes the structural transformation process in LAC and evaluates if the "premature de-industrialization" patterns observed in the data are a result of distortive policies or if they represent an efficient (i.e. growth maximizing) reallocation of resources responding to the underlying drivers of structural transformation. An important message of the report is that policy makers should not focus on sectoral size but rather on productivity growth. The emergence of new technologies--under the banner of the "4th Industrial Revolution"--suggests that opportunities for further industrialization or re-industrialization are likely to be limited in many developing countries. Looking forward, the region needs to develop a productivity agenda with a special focus on the services sector. Already the largest employer in the region with over 60 percent of the workforce, the services sector is expected to grow even further and play an increasingly crucial role as an input provider to the larger economy. In short, there is a need for a comprehensive set of service-sector oriented policies. The report concludes that three major economic forces are changing the nature of work and the demand for skills. First, the structural transformation process, in general, and the de-industrialization pattern observed for the economies in the region, in particular, imply that future job growth will occur mainly in the services sector. Second, the shift in economic structure is being accompanied by a transformation of the occupational structure within broad economic sectors. The importance of service occupations--those that produce intangible value added such as marketers, managers, designers--is increasing in all sectors of the economy. Third, as machines replace humans in carrying out simpler, more routine tasks, workers will have to adapt and perform a different set of tasks in the workplace. What may become more important as new automation technologies are adopted in LAC countries, is adult learning and re-training.
