CARACAS, Venezuela — Economic pledges may be par for the course in election campaigns, but in hyperinflationary Venezuela, the candidates’ dueling promises are going further, with the incumbent vowing to lop a few zeros off the currency, while his main challenger calls for the adoption of the U.S. dollar.

President Nicolás Maduro late Thursday briefly outlined his monetary rescue plan. In a country where a dozen eggs can cost 250,000 bolivars ($5) amid worsening inflation, he would chop three zeros off the currency — arguably bringing the price for those eggs down to 250.
