At the cost of loss

My view is that the new policy buys a trivial new incentive at the cost of a modest loss in deterrence.

我的看法是，新政策以温和的威慑损失为代价买了一份微不足道的新动机。

The loss of competitiveness can be reversed (Ireland is doing it), but only at the cost of a long-term decline in wages and demand, which will require in turn even more fiscal retrenchment.

竞争缺失可以修复（爱尔兰正在这样做），但要付出工资和需求长期下跌的成本，这样一来势必需要做出更多财政紧缩。

The cost of bandwidth is seen as one reason YouTube still operates at a loss.

频宽成本被视为YouTube营运仍处于亏损状态的主因之一。
