In addition, inflation movement up or down has become increasing synchronized across the countries of the world.

Setting up your own firm for a firm experiment (World Bank blogs)

The typical approach to examining how workers, consumers, or governments interact with a firm has been for researchers to find a willing firm owner and convince them to run experiments. Examples include Bandiera et al. working with a UK fruit-farmer to test different payment incentives for immigrant workers; Bloom et al. working with a Chinese travel agency to test the effect of letting workers work from home; and Adhvaryu et al. working with an Indian garment firm to measure impacts of soft-skills training for workers and of introducing LED-lighting. However, finding/persuading a firm to do the experiment that a researcher would like to do can be hard, with many of these existing samples coming about through a researcher having a former student or relative who runs one of these firms.

The challenges of electoral democracy are becoming increasingly visible worldwide. Elite capture, corruption and patronage are serious concerns, and the legitimacy of some elections has come under critical scrutiny. This has led to a revival of the idea of direct democracy – giving power directly to groups of people to make collective decisions.
