Starting with Chile in the early 1980s, Latin American countries have pushed telecommunications reform to create regulatory environments that encourage private investment, especially foreign investment. I look at trends in 25 Latin American and Caribbean countries during 1980-2001 and construct an index based on the following aspects: autonomy, accountability, clarity of roles and objectives, transparency and participation, and the type of legal mandate that creates a regulatory body. The index shows clearly that, in general, most countries embraced strong regulatory reforms along the lines recommended by experts and practitioners. The index also correlates well with main political, risk, economic and telecommunications variables. © 2003 Elsevier Ltd. All rights reserved.

Empezando con Chile a comienzos de 1980, los países de América Latina han profundizado la reforma a las telecomunicaciones para crear un entorno regulatorio que incentive la inversión privada, en particular la inversión extranjera. En este artículo, trabajo las tendencias regulatorias en el sector telecomunicaciones de 24 países latinoamericanos y del caribe durante el período 1980-1997 y construyo un índice basado en : autonomía, rendición de cuentas, claridad de las funciones y objetivos, transparencia y participación, y el tipo de mandato legal que crea el ente regulador. El índice muestra que, en promedio, la mayoría de los países llevaron a cabo fuertes reformas regulatorias en la dirección sugerida por expertos e investigadores. El índice también se correlación bien con varias variables políticas, de riesgo, económicas y de telecomunicaciones. ; Starting with Chile in the early 1980s, Latin American countries have pushed telecommunications reform to create regulatory environments that encourage private investment, especially foreign investment.

El artículo analiza la entrada de firmas y rotación de la productividad promedio en la industria petroquímica colombiana para el período 1974-1998. Los resultados muestran que los entrantes exitosos dieron forma a la productividad de la industria e indujeron a la reestructuración de las plantas existentes. Los flujos de entrada crecieron constantemente en el sector de plásticos, a pesar de los cambios de política comercial. La descomposición del crecimiento de la productividad total de los factores muestra que el efecto de las empresas establecidas domina sobre el efecto de rotación de empresas. Los resultados econométricos sugieren que las barreras a la entrada, asociadas con el licenciamiento de la tecnología y la dependencia de materias primas importadas disuaden la entrada, mientras que variables complementarias del mercado como los niveles de productividad, crecimiento en la construcción de vivienda y competencia periférica inducen la entrada de firmas. Palabras clave: entrada, rotación, productividad total factorial, industria petroquímica.

Over one million firms around the world have adopted a Quality Management System (QMS) that conforms to ISO 9001 certification in 2015 and recent figures show that certifications have rapidly increased in emerging economies. ISO 9001 is considered a signal of high quality for products or services in markets with large imported competition or firms competing in international markets. However, implementing ISO 9001 certification entails large costs to companies for documentation of operating procedures, training, internal auditing, and corrective action. The impact of QMS on firm performance is unknown in developing economies and is still under-researched for more developed countries. This paper takes advantage of unique data on the status of certified and non-certified manufacturing firms in Colombia (an emerging economy) and matches it with firm performance. In 2006, the Colombian government launched policies to reduce the cost of adopting certification. We use this change to implement a difference-in-differences specification on panel data of certified and non-certified firms by matching samples at the year 2003, three years before the policy change. This is the most comparable data possible. Our findings suggest that firms that adopt ISO 9001 certification increase labor productivity (measured as added value over labor) by 12 percent, and sales per employee and wages by 8 percent. The effect is larger for firms that adopted certifications two years after the new policies compared with firms that adopted them immediately. The potential mechanism to explain gains in firm performance is human capital because, prior to the changes, firms with more temporary workers could not take advantage of certification
