   Strategic choices of migrants and smugglers in the Central Mediterranean sea.

   “Leveraging data on aggregate migration flows and individual migration incidents, we estimate how migrants and smugglers have reacted to changes in the border enforcement regime, namely the rise in interceptions by the Libyan Coast Guard starting in 2017 and the corresponding decrease in the probability of rescue to Europe. We find support for a deterrence effect in which attempted crossings along the Central Mediterranean route declined, and a diversion effect in which some migrants substituted to the Western Mediterranean route. At the same time, smugglers adapted their tactics. Using a strategic model of the smuggler's choice of boat size, we estimate how smugglers trade off between the short-run payoffs to launching overcrowded boats and the long-run costs of making less successful crossing attempts under different levels of enforcement. Taken together, these analyses shed light on how the integration of incident- and flow-level datasets can inform ongoing migration policy debates and identify potential consequences of changing enforcement regimes.”

   Political and environmental risks influence migration and human smuggling across the Mediterranean Sea.

   “Since 2007 the number of refugees fleeing conflict and violence has doubled to more than 25 million. We leverage high frequency data on migration, sea conditions, and riots to investigate how political and environmental risks influence migration and human smuggling across the Mediterranean Sea. We report results from two observational studies. A high frequency time-series study demonstrates that risks alter migration patterns. An event study design demonstrates the effectiveness of a policy intervention that targeted Libyan militias engaged in human smuggling. The results highlight the important role of environmental and political risks in transit countries and their implications for migration and human smuggling.”

   “The Gulf of Aden (Arabic: خليج عدن; Somali: Gacanka Cadmeed) is a deepwater gulf of the Indian Ocean between Yemen to the north, the Arabian Sea to the east, Djibouti to the west, and the Guardafui Channel, the Socotra Archipelago, Puntland in Somalia and Somaliland to the south. In the northwest, it connects with the Red Sea through the Bab-el-Mandeb strait, and it connects with the Arabian Sea to the east. To the west, it narrows into the Gulf of Tadjoura in Djibouti. The Aden Ridge lies along the middle of the gulf, and tectonic activity at the ridge is causing the gulf to widen by about 15 mm (0.59 in) per year. The ancient Greeks regarded the gulf as one of the most important parts of the "Erythraean Sea". It later came to be dominated by Muslims, as the area around the gulf converted to Islam. From the late 1960s onwards, there was an increased Soviet naval presence in the Gulf. The importance of the Gulf of Aden declined while the Suez Canal was closed, but it was revitalized when the canal was reopened in 1975, after being deepened and widened by the Egyptian government.”
