The 1990s in Latin America: Another Decade of Persistent Inequality [PDF]
This paper argues that there is no country in Latin America where we can confidently say that income inequality improved during the 1990s. We document this fact for the 15 countries where comparable household surveys, covering most of the population, are

Impact of Trap Depth on the Steady‐State and Transient Photoluminescence in Halide Perovskite Films
Advanced Energy Materials, EarlyView.The presence of shallow traps in halide perovskites is frequently postulated by density functional theory calculations. This review studies the implications of recombination‐active shallow traps on steady‐state and transient recombination kinetics. How to identify shallow traps and how the depth of the traps and their density are reflected in different

Rising income inequality in the U.S. was fuelled by Ronald Reagan’s attacks on union strength, and continued by Bill Clinton’s financial deregulation [PDF]
, 2014 Income inequality in the U.S. has grown rapidly over the past thirty years, but almost no research has found that shifts in government policy led to greater inequality and the associated stagnation in middle incomes.

The Financial Status and Local Credit Market Conditions of U.S. Farms Engaged in Multiple Borrowing
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Agricultural producers often borrow from multiple lenders, raising concerns about credit risk and monitoring. We construct detailed farm‐level measures of how debt is distributed across lenders and examine how farm financial status and the physical presence of local lenders are linked to this practice.

Power System Topological Observability Analysis Using Improved Hopfield Neural Network [PDF]
Journal of Electrical and Electronics Engineering, 2016 This paper solves the Topological Observability (TO) problem of a power system using the new methodology based on Improved Hopfield Neural Network (IHNN). This IHNN can solve the combinatorial optimization problem with inequality constraints.
