Donald J . Boyd, Hamil ton Lankford, Susanna Loeb, and James H. Wyckoff School districts are confronting difficult choices in the aftermath of the financial crisis. In prior recessions, districts often muddled through by imposing a combination of tax increases and expenditure cuts that avoided involuntary personnel reductions. Today, the financial imbalance in many school districts is so larg...

The paper presents the problem of choosing the representatives in an assembly when the whole electoral region is subdivided into electoral districts. Because of the two dimensions, geographical (districts) and political (parties), the problem is called bi-apportionment. Often the allocation of seats to districts is pre-determined and furthermore distorted —meaning that the ratios of the number ...

The fundamental organizing elements of the New Urbanism are the neighborhood, the district and the corridor. Neighborhoods are urbanized areas with a balanced mix of human activity; districts are areas dominated by a single activity; corridors are connectors and separators of neighborhoods and districts. A single neighborhood standing free in the landscape is a village. Cities and towns are mad...

The ability of nonexperimental estimators to match impact estimates derived from random assignment is examined using data from the evaluation of two interdistrict magnet schools. As in previous within-study comparisons, nonexperimental estimates differ from estimates based on random assignment when nonexperimental estimators are implemented without pretreatment measures of academic performance....

It has been argued that the effects of the desegregation of public schools from the late 1960s onward were limited and short-lived, in part because of white flight from desegregating districts and in part because legal decisions in the 1990s released many districts from court orders. Data presented here for 1970-2000 show that small increases in segregation between districts were outweighed by ...

Indonesia has a tradition of corruption among local officials who harass and collect bribes from firms. This paper examines whether corruption is affected by a change in institutions introducing local democratization and by party composition of local assemblies. Democratization occurred in 1999 and decentralization in 2001. We have firm-level data for 2001 and 2004. The 2001 data benchmark corr...

Historically, the number of public school districts in the United States has decreased despite a dramatic increase in the number of students enrolled. Although public school district consolidation has impacted districts of all sizes, since the late 1930’s smaller rural districts facing dwindling community resources have merged or consolidated with each other, resulting in fewer school districts...
