To reduce SDG tradeoffs in infrastructure provision, and to inform searches for SDG synergies, the authors show that roads’ impacts on Brazilian Amazon forests varied significantly across frontiers. Impacts varied predictably with prior development – prior roads and prior deforestation – and, further, in a pattern that suggests a potential synergy for roads between forests and urban growth. For multiple periods of roads investments, the authors estimate forest impacts for high, medium and low prior roads and deforestation. For each setting, census-tract observations are numerous.

The Chilean mussel aquaculture industry is a prime example of a thriving industry.  However, the industry growth rate, aquaculture concessions and market prices have stabilized signaling a shift in the industry from exponential growth to, if handled correctly, economic stability.  Here we used perception research, an efficient tool to inform on the implementation of management strategies, to provide policy makers with the tools necessary for the development of strategies that will aid in the sustainability of the industry through its current shift.  We assessed the perception

Small hydropower (SHP) has existed for more than a century in Colombia, and is gaining reserved interest as an option to mitigating climate change. In this paper we investigate the prospects for SHP in Colombia based on an analysis of economies-of-scale and learning-by-doing effects. We created an inventory of SHP plants realized in Colombia between 1900 and 2013, and focused on grid-connected SHP stations only. In the economies-of-scale part of our analysis we considered all SHP plants with a capacity lower than 20 MW.

Mining represents an important economic sector in almost all countries, especially the developing ones. The planning in this area is complex due to the interaction between different aspects like economic factors, environmental and social issues, and government regulation. A tool for policy analysis is needed to understand and test the effects of new and existing policies and avoid unanticipated side effects.

Coal has fueled China's rapid growth in recent decades, but it also severely pollutes the air and causes many health issues. The magnitude of the health damage caused by air pollution depends on the location of emission sources. In this paper, we look into the spatial distribution of coal-fired power plants, which are the major emission sources in China, and investigate the determining factors behind the distribution.

Does public transportation reduce vehicle congestion? Using a regression-discontinuity framework, we examine the effect of six subway openings on short-run congestion in Beijing between 2009 and 2015. We find that vehicle congestion drops sharply immediately after new subway openings. In our central specification, each of the subway openings decreased delay times by an average of 15% in the short run over the city of Beijing.

Using the data of SOEs and Non-SOEs in industrial sector of China from 1998 to 2007, we investigate the impact of privatization on TFP. We construct a difference in difference model and use propensity score method to avoid the selection bias. We use the type of enterprises registration to identify the SOEs and define the privatization. The regress results show, privatization of SOEs can improve the efficiency of enterprises significantly. Some characteristics of firms will affect the effect of privatization.

Africa is endowed with an incredible amount of natural resources of which
the extractive sector is a key component. Unfortunately, however, the continent
is characterized by a paradox of plenty or resource curse, depicting a situation
of abundant resources that have not translated into economic growth and
prosperity for the population. The potential role of the extractive sector is
further affected by global volatilities. This article reviews the importance of
the extractive sector to selected African countries. It identifies sources of

We pair a firm-level panel of annual industrial output with a fine-scale daily weather data set, to estimate the responses of industrial output to temperature changes in China. We have four primary findings. First, industrial output is nonlinear in temperature changes. With seasonal average temperatures as temperature variables, output responds positively to higher spring temperatures and negatively to elevated summer temperatures.

Compared with the developed countries, the developing countries could be more vulnerable to oil supply disruptions due to their lack of strategic petroleum reserves (SPRs). Several developing countries, including China and India, are establishing their SPRs to ensure energy security. In the common world oil market, one country's SPR decisions can be affected by the decisions of other countries.
