This paper develops a generalization of the widely used difference-in-differences method for evaluating the effects of policy changes. We propose a model that allows the control and treatment groups to have different average benefits from the treatment. The assumptions of the proposed model are invar...
First, the propensity score matching method combined with the SDID (PSM-SDID) model is used to find a suitable control group (non pilot city) for the treatment group (pilot city). Second, we use two other spatial weight matrices, namely, the adjacency matrix (W2) and nested matrix (W3...
First, as noted above, there are problems with the implementation of the difference-in-difference method, which mean that the treatment and control groups have not been clearly distinguished. Second, a reading of the tariff regulations of the period, and the decisions on additional duties, has ...
and South America sub-regions. One of the impact evaluation methods, Difference in Difference (DID), will determine the overall and sub-regional causal effects. This evaluation aims to use the DID as an alternative method for assessing a policy and interventions’ causal effect in the maritime ...
Difference-in-differences is one of the most used identification strategies in empirical work in economics. This chapter reviews a number of important, recent developments related to difference-in-differences. First, this chapter reviews recent work pointing out limitations of two-way fixed-effects reg...
