15.9: 劳动力的市场供给

人们愿意和能够在市场上完成的总工作量取决于每个工人共同提供的劳动数量。

在劳动力市场中，大量的工人提供了劳动力。劳动力提供的工作总量取决于现行的工资水平。工资与市场上所有工人提供的劳动力数量之间的关系能够用劳动力的市场供给曲线来进行表示。

向上倾斜的劳动力供给曲线

劳动力供给曲线通常是向上倾斜的，这表明在其他因素保持不变的情况下，较高的工资会导致劳动力供给量的增加。相反地，在相同的条件下，较低的工资则会减少劳动力的供给量。

较高的工资能够通过增加收入和提高休闲的机会成本来激励个人提供更多的劳动力。较高的工资能够吸引新的工人进入劳动力市场并鼓励现有工人增加工作时间。在分析劳动力的供给时，通常会方便地假设劳动力供给量的变化主要反映了工人数量的增加，而不仅仅是工作时间的变化。

劳动力是一种独特的生产要素。虽然劳动力是由公司需要的，但它是由生活在家庭中的个人提供的。

劳动力的市场供给曲线说明了市场工资率与工人愿意在市场上提供的劳动力数量之间的关系，假设除了市场工资之外没有其他变化。

它是向上倾斜的。

这意味着，如果市场工资率较高，供应的劳动力数量会增加，而当工资降低时，供应的数量就会减少。

更高的工资可能会吸引新进入劳动力市场的人或鼓励现有工人工作更多的时间。

然而，为了便于分析，通常假设供应给市场的劳动力数量是指随着工资上涨而增加的工人数量。这有助于关注市场上应对工资变化的劳动力的整体可用性。

在达到一定工资后，个人的劳动供给曲线可能会向后弯曲。当更高工资的额外收入允许在不减少收入的情况下消耗更多的闲暇时间时，就会出现这种情况。然而，劳动力的市场供给曲线被假设为向上倾斜，因为更高的工资会鼓励更多的工人进入劳动力市场。
