In this paper, we develop an econometric model to estimate the impacts of Electronic Vehicle Management Systems (EVMS) on the load factor (LF) of heavy trucks using data at the operational level. This technology is supposed to improve capacity utilization by reducing coordination costs between...

The poverty impact of indirect tax reforms is analyzed using sequential stochastic dominance methods. This allows agents to differ in dimensions that cannot always be precisely captured within the usual money-metric indicators of living standards. Examples of such dimensions include household...

We propose graphical methods to determine whether commodity-tax changes are "socially efficient", in the sense of improving social welfare or decreasing poverty for large classes of social welfare and poverty indices. We also derive estimators of critical poverty lines and economic efficiency...
