The U.S. economy has been going through a striking structural transformation--the secular reallocation of employment across sectors--over the past several decades. We propose a decomposition framework to assess the contributions of various margins of firm dynamics to this shift. Using firm-level data, we find that at least 50 percent of the adjustment has been taking place along the entry margin, due to sectors receiving different shares of startup employment than their employment shares. The rest is mostly due to life cycle differences across sectors. Declining overall entry has a small but growing effect of dampening structural transformation.

Seventeen years into the life of the African Growth and Opportunities Act (AGOA), two key issues stand out: first, that the preference utilization rate—as indicated by the meagre increases in African exports to the United States—remains marginal; and second, that the AGOA initiative has not helped build diversified African economies. This reality in turn raises two critical issues: that Africa's structural challenges need to be addressed; and that extensions of the AGOA in and of themselves may not be the solution for the continent's economic development. Therefore, looking toward 2025 is an opportunity to have a fresh discussion with the United States, one focused on placing the African economic development challenge at the heart of the dialogue. This requires designing a new model grounded in Africa's aspirations for structural transformation of its economies from primary product to industrial product exporters.

This program has been organized by the EMSA to commensurate the 50th anniversary of the experimental verification of the wave nature of the electron. Davisson and Germer in the U.S. and Thomson and Reid in Britian accomplished this at about the same time. Their findings were published in Nature in 1927 by mutual agreement since their independent efforts had led to the same conclusion at about the same time. In 1937 Davisson and Thomson shared the Nobel Prize in physics for demonstrating the wave nature of the electron deduced in 1924 by Louis de Broglie.The Davisson experiments (1921-1927) were concerned with the angular distribution of secondary electron emission from nickel surfaces produced by 150 volt primary electrons. The motivation was the effect of secondary emission on the characteristics of vacuum tubes but significant deviations from the results expected for a corpuscular electron led to a diffraction interpretation suggested by Elasser in 1925.
