AVI: The Shift in the Tax Burden
As proposed, the Actual Value Initiative (AVI), Philadelphia's sweeping property tax overhaul, is revenue neutral. The plan is to raise the same amount of revenue through real estate taxes, 100 billion in 2014. For 2013, that share was 53.9 percent. This difference of 6 percentage points would result in $72 million in additional taxes for homeowners as a group, making AVI not revenue neutral for them
Shuttered Public Schools: The Struggle to Bring Old Buildings New Life
Large-scale public school closures have become a fact of life in many American cities, and that trend is not likely to stop now. This report looks at what happens to the buildings themselves, studying the experiences of Philadelphia and 11 other cities that have decommissioned large numbers of schools in recent years: Atlanta, Chicago, Cincinnati, Cleveland, Detroit, Kansas City, Mo., Milwaukee, Pittsburgh, St. Louis, Tulsa and Washington
Revolution in the Defence Electronics Market? An Economic Analysis of Sectoral Change
Within the defence sector there have been marked changes in the nature of the composite industries. This is particularly true of the electronics industry which continues to grow in importance, with electronic components built into nearly every weapons system and piece of equipment. Given the “Revolution in Military Affairs” (RMA) it seems certain that this growth will continue, impacting on both product and process. The result, however, may not be the contestable open market many expect (and hope for) as Network Enabled Warfare may result in new entrants, such as IT specialist and increased competition. Alternatively the nature of the market may continue to benefit the incumbents. This paper presents an analysis of the changes taking place in the industry using firm-level, primary, survey-based, qualitative data on corporate conduct. The results suggest that in practice the incumbents do seem to be in a strong position. The new demands of the customer require much more than mere technical capability. Specialists who do not have established industry relationships, who do not understand industry “protocols” and who cannot communicate effectively with the customer are unlikely to survive. This suggests that rather than new entrants, there may in fact be exits from the industry and further consolidation.
Isomorphisms between big mapping class groups
We show that any isomorphism between mapping class groups of orientable
infinite-type surfaces is induced by a homeomorphism between the surfaces. Our
argument additionally applies to automorphisms between finite-index subgroups
of these `big' mapping class groups and shows that each finite-index subgroup
has finite outer automorphism group. As a key ingredient, we prove that all
simplicial automorphisms between curve complexes of infinite-type orientable
surfaces are induced by homeomorphisms.Comment: v3: 11 pages; updated and added references; final version to appear
