Military Rivalries, Alliances and Taxation : The International Origins of Modern Fiscal Contracts

Bellicist theories of comparative development predict increases in taxation as the result of military rivalries. Others claim that this causal relationship is contingent on particular geographical, institutional, and historical conditions. In this paper, we explore the conditional effects of military rivalries on taxation during the 19th and 20th centuries using time-series cross-section models. W

Robust Non-Negative Least Squares Using Sparsity

Sparse, non-negative signals occur in many applications. To recover such signals, estimation posed as non-negative least squares problems have proven to be fruitful. Efficient algorithms with high accuracy have been proposed, but many of them assume either perfect knowledge of the dictionary generating the signal, or attempts to explain deviations from this dictionary by attributing them to compon
