Foreign producers reduced their prices by 5.2 percent relative to the control group following the 25 percent tariff, absorbing about 20 percent of the tariff rate. The remaining 80 percent was passed forward as higher costs to US importers. On a bottle of wine for which the producer charged $5 before the tariff was imposed and $4.74 after, the tariff payment would have been $1.19. Importers, who the researchers estimate apply an 80 percent markup to the price they pay to producers, would have charged $9 to distributors before the tariff was imposed. The researchers estimate that they raised their prices to distributors by 5.4 percent, but on a base of $9 (= 1.8 x $5). This increase would be $0.49, so importers would be absorbing additional costs since they would pay $5.93 (= 1.25 x $4.74) to the producer and in tariffs. All told, the importer’s dollar margins per bottle declined by $0.44.
As you can see, modules in Modular Design are not layers. Names like “Domain”, “Application” are not desirable, because they clearly favor a technical separation. In such designs the business logic related to one process is often scattered and at the same time unrelated logic is squeezed into one “module”. Both cases make it harder to reason about the system.

Пума набросилась на ши-тцу Маквей по кличке Деклан во время ночной прогулки. Женщина возвращалась домой, пятилетний Деклан на поводке бежал за ней. Вдруг недалеко от входной двери Маквей почувствовала, как собака натянула поводок, и услышала позади странные звуки. Она обернулась и увидела, как ее маленькую собаку схватила в зубы пума.
