4. DD Example: Kan and Lin (2011)
Taiwan’s LSL attempts to regulate all aspects of employment relationship, for example, labor contract, wage, overtime payments and hours, retirement and severance payments, compensations for occupational accidents, and maternity benefits.
Elliott Fan: Labor 2017 Fall Lecture 11

5. DD Example: Kan and Lin (2011)
Some of the LSL labor protection measures were new, for example, the prohibition of firing at will.
Firstly, employers have to give an advance notice before dismissing an employee.
Secondly, LSL imposes a higher severance pay than previous labor laws.
An employer can dismiss an employee only if the business is closing down, suspended for more than 1 month, suffering from a loss, or when the employee is not able to perform the duties satisfactorily or violates the work rule.

Enforcement
The poor enforcement of LSL has also contributed to the low compliance rate of LSL in the early years of its implementations.
During the first 3 years of LSL’s enactment the Department of Labor of the Ministry of Interior was in charge of the enforcement of LSL. However, inspection and prosecution were carried out by a multitude of local labor agencies belonging to the Taiwan Provincial Government, the Taipei and Kaohsiung municipalities, and the Ministry of Economic Affairs.

Definitions:
Rate of hiring:
HRATEit = (HIREit /EMPit−1) × 100
Rate of separating:
SRATEit = (SEPARATEit /EMPit−1) × 100
Worker flow:
WFLOWit = (HIREit + SEPARATEit /EMPit−1) × 100
Job reallocation rate:
JREALLOCit = (| EMPit − EMPit−1|/EMPit−1) ×100,
= (| JCit − JDit |/EMPit−1) × 100,
= (| HIREit − SEPARATEit |/EMPit−1)×100
