where a is a constant. The demand of labour could be considered as a “derived” demand in
               which the firm’s output is proportional to labour demand in the firm. In this sense, the output
               function can be used for the employment function in the firm (ni). In this employment function,
               the price (p) is replaced with the wage (w) in the output function. It means that the employment
               function can be expressed as;

                n   (m  w ) a  (w   ) w                                                                 (13.2)
                                  i
                 i

               This employment function may be simplified by assuming that employment and wage level is
               the same in all firms. In this simplified version, the level of employment at time  t can be
               expressed as;

                n  m   w                                                                                      (13.3)
                 t
                      t
                          t

               where nt is the employment level at time t, mt is the level of money supply at time t and wt is
               the wage level at time t. The level of employment would be determined by the difference
               between the level of money supply and level of wage rate. In the case that the increase in money
               supply is greater than the increase in wage level, this would cause a positive effect on the
               employment level. By contrast, in the reverse case that the increase in wage level is greater
               than the increase in money supply, this would cause a negative effect on the employment level.

               Under  the  insider  model  of  employment,  the  insider  in  the  firm  would  have  a  maximum
                                                                                  e
               bargaining power to ensure that the expected level of employment (n ) is equal to the level of
               employment at time of the negotiation ( n  1  t  ). It would mean that the bargaining parameter (β)
               is  equal  to  unity  under  this  insider  model  of  employment.  In  the  case  that  the  insider’s
               bargaining power is less than the maximum value, the expected level of employment could be
               less than the level of employment at time of the negotiation. The employment function can be
               reformulated as:

                n   (n  )  (m  m  e )                                                                (13.4)
                 t      t 1    t    t

               where β is a bargaining parameter that would measure the level of strength of insider in the
               firm.  This  employment  formula  indicates  that  some  insiders  could  lose  their  employment
               during  an  economic  recession  if  β  is  less  than  one.  More  importantly,  if  the  bargaining
               parameter is less than unity, the monetary shock will disappear in the long-run. It means that a
               monetary  shock  would  have  a  transitory  impact  on  the  employment.  In  this  case,  the
               unemployment rates would follow a stationary process. In other words, a higher-than-normal
               unemployment rate would revert to an equilibrium level. However, if the bargaining parameter
               is equal to unity, a monetary shock would not disappear. In this case, the unemployment rates
               would follow a unit root process (Furuoka 2012; Furuoka, 2017a; Furuoka, 2017b).

               In a nutshell, the main point of this theoretical framework on the employment model is that the
               strength of the insider in the firm will determine the labour market dynamics. In other words,
               the insider power could be the main element which determines whether unemployment rate
               would follow the stationary process. It means that the unemployment rate could follow a unit
