For individuals who experience job loss, enrollment in post-secondary programs may provide an opportunity to improve future employment outcomes. However, decisions to enroll may be hampered by insufficient information about the benefits and costs and the necessary steps and assistance available to facilitate such investments. Using variation in the dissemination and timing of letters sent to UI recipients containing this information, we find that individuals sent the information are 40% more likely to enroll. These findings suggest that well-coordinated information interventions delivered with institutional support may be more effective than raising the generosity of existing government programs in increasing participation.

Despite publicity given to the successes of British and American codebreakers during the Second World War, the study of signals intelligence is still complicated by governmental secrecy over even the most elderly peacetime sigint. This book, first published in 1986, lifts the veil on some of these historical secrets. Christopher Andrew and Keith Neilson cast new light on how Tsarist codebreakers penetrated British code and cypher systems. John Chapman's study of German military codebreaking represents a major advance in our understanding of cryptanalysis during the Weimar Republic. The history of the Government Code and Cypher School - forerunner of today's GCHQ - by its operational head, the late A.G. Denniston, provides both a general assessment of the achievements of British cryptanalysis between the wars and a tantalising glimpse of what historians may one day find in GCHQ's forbidden archives. The distinguished cryptanalyst of Bletchley Park, the late Gordon Welchman, describes in detail how the Ultra programme defeated the German Enigma machine, while another Bletchley Park cryptographer, Christopher Morris, reminds us in his account of the valuable work on hand cyphers that wartime sigint consisted of much more than Ultra. Roger Austin's study of surveillance under the Vichy regime shows the continuing importance of older and simpler methods of message interception such as letter-opening. Taken together, the articles establish sigint as an essential field of study for both the modern historian and the political scientist.

The history of espionage is far older than any of today's intelligence agencies, yet the long history of intelligence operations has been largely forgotten. The first mention of espionage in world literature is in the Book of Exodus.'God sent out spies into the land of Canaan'. From there, Christopher Andrew traces the shift in the ancient world from divination to what we would recognize as attempts to gather real intelligence in the conduct of military operations, and considers how far ahead of the West - at that time - China and India were. He charts the development of intelligence and security operations and capacity through, amongst others, Renaissance Venice, Elizabethan England, Revolutionary America, Napoleonic France, right up to sophisticated modern activities of which he is the world's best-informed interpreter. What difference have security and intelligence operations made to course of history? Why have they so often forgotten by later practitioners? This fascinating book provides the answers.
