This paper provides new, global evidence on the relationship between trade liberalization and deforestation. Using event studies around the enactment of regional trade agreements (RTAs) on ...

Trade liberalization can spur environmental degradation. Concerns over these adverse impacts have led to a debate over the need for environmental provisions in regional trade agreements (RTAs), however the effectiveness of such provisions is unknown. This paper provides new causal evidence that environmental provisions are effective in limiting deforestation following the entry into force of RTAs. It exploits high-resolution, satellite-derived estimates of deforestation and identify the content of RTAs using a new dataset with detailed information on individual provisions. Accounting for the potential endogeneity of environmental provisions in RTAs, the paper finds that the inclusion of specific provisions aimed at protecting forests and/or biodiversity entirely offsets the net increases in forest loss observed in similar RTAs without such provisions. The inclusion of these provisions limits agricultural land expansion, but does not completely offset increases in total agricultural production. The effects are concentrated in tropical, developing countries with greater biodiversity.

Global efforts to protect biodiversity and slow deforestation rely heavily on the establishment of protected areas; land set aside that cannot be deforested or developed. This paper studies the macro-level relationship between rule of law and variation in avoided deforestation from protected areas. Using recent global satellite data from 2000 to 2012, I estimate the country-level avoided deforestation of protected areas established in this period via nearest-neighbor matching. I then use weighted least-squares regressions to explain country-level variation in estimated avoided deforestation as a function of a country’s governance characteristics as well as other country-level controls. Across 71 countries in this study period, protected areas were more effective in countries with higher levels of corruption control and protection of property rights, protected areas were more effective in more democratic countries, and there appears to be no relationship between political stability and avoided deforestation from protected areas.

Despite a lack of rigorous empirical evidence, reduced crime is often touted as a potential benefit in the debate over increasing border infrastructure (i.e. border walls). This paper examines the effect of the Secure Fence Act of 2006, which led to unprecedented barrier construction along the US-Mexico border, on local crime using geospatial data on dates and locations of border wall construction. Synthetic control estimates across twelve border counties find no systematic evidence that border infrastructure reduced property or violent crime rates in the counties in which it was built. Further analysis using matched panel models indicates no effect on property crime rates and that observed declines in violent crime rates precede barrier construction, not the other way around. Taken together, this paper finds potential crime reductions are not a compelling argument towards the benefits of expanding border infrastructure.

This paper studies the underlying relationship between agricultural productivity and deforestation by analyzing the impacts of a large fertilizer and seed subsidy program in Malawi. In the absence of well-defined subsidy eligibility criteria, we demonstrate that areas with a high proportion of individuals of the same ethnicity as the president received more subsidized fertilizer and deforested less compared to areas with other predominant ethnicities. We provide evidence that subsidized fertilizer increased yields and reduced pressure to expand agriculture and that the findings are not confounded by increases in public sector employment or other public assistance programs. The results suggest that policies aimed at increasing small-scale agricultural productivity may have positive environmental spillovers.

This paper studies the relationship between land tenure for smallholder agriculture and deforestation. We combine high resolution satellite data on deforestation with rich household and commune-level, biannual panel data from Vietnam. We study two margins of tenure security, whether a household has any land title (extensive) and the share of a household’s land held in title (intensive). Using a household-fixed effects model, we find the increases in crop production and land investment associated with holding land title are driven by the intensive margin. We then aggregate the survey data to the commune-level and find evidence that marginal increases in extensive tenure (share of households with any land title) increase deforestation holding constant the average intensive tenure (average share of land held in tenure among those with land title). We find some evidence that increasing the intensive margin of tenure (holding constant the extensive tenure) decreases deforestation. These results present a more nuanced view of the tenure-deforestation relationship than is prevalent in the existing literature.

Fake antivirus (AV) programs have been utilized to defraud millions of computer users into paying as much as one hundred dollars for a phony software license. As a result, fake AV software has evolved into one of the most lucrative criminal operations on the Internet. In this paper, we examine the operations of three large-scale fake AV businesses, lasting from three months to more than two years. More precisely, we present the results of our analysis on a trove of data obtained from several backend servers that the cybercriminals used to drive their scam operations. Our investigations reveal that these three fake AV businesses had earned a combined revenue of more than $130 million dollars. A particular focus of our analysis is on the financial and economic aspects of the scam, which involves legitimate credit card networks as well as more dubious payment processors. In particular, we present an economic model that demonstrates that fake AV companies are actively monitoring the refunds (chargebacks) that customers demand from their credit card providers. When the number of chargebacks increases in a short interval, the fake AV companies react to customer complaints by granting more refunds. This lowers the rate of chargebacks and ensures that a fake AV company can stay in business for a longer period of time.9pc]First author has been considered as the corresponding author. Please check. However, this behavior also leads to unusual patterns in chargebacks, which can potentially be leveraged by vigilant payment processors and credit card companies to identify and ban fraudulent firms.
