노력의 수준이 해고의 순서 및 생산성에 미치는 영향
Abstract
본 논문은 노동시장에서 관찰되는 비자발적 실업과 해고의 존재를 노동계약모형을 통하여 설명하는 동시에, 생산성이 경기변동에 따라 순경기적으로 변화하는 현상을 설명하려고 하는 시도이다. 대부분 동질적 노동을 가정?構? 있는 노동계약모형의 경우 노동시간공유(work-sharing)가 가능하다면 해고 및 자발적 실업의 존재를 설명할 수 없다. 본 연구에서는 노동이 관찰 가능한 비동질성을 보유하고 있는 경우 노동시간공유의 가능성 여부에 관계없이 해고 및 비자발적, 실업이 존재할 수 있다는 것을 보인다. 한편 암묵적 계약모형과 효율임금모형 모두 생산성이 순경기적(procyclical)으로 변화한다는 경험적인 사실을 설명하지 못하고 오히려 경험적 사실과 반대되는 예측을 하고 있다. 본 논문은 노동계약모형에 효율임금모형의 요소인 노력수준을 명시적으로 도입할 경우 순경기적인 생산성의 변화를 설명할 수 있음을 밝히고 있다.
This paper shows that productivity can move procyclically over business cycle while the previous implicit contract and efficiency wage models incur countercyclical movement which is opposite to the empirical results. It also shows layoffs are possible even when there is work sharing, and layoffs occur in order of effort level or efficiency unit of labor. Moreover, this layoff pattern strengthens our arguments about procyclical productivity movement. If effort level increases by seniority this results implies that layoffs occur by seniority rule. This result also can be applied to explain high unemployment rate in young, woman, or minor ethnical worker groups. finally, the basic model was extended to derive self-enforceable contract when the contract is not legally enforceable.
