Abstract: This paper is to clarify the relationship between ICT
and income inequality. To do so, we develop the general equilibrium
model with ICT investment, obtain the equilibrium solutions, and then
simulate the model with these solutions for some OECD countries.
As a result, generally, during the corresponding periods we confirm
that the relationship between ICT investment and income inequality
is positive. In this mode, the increment of the ratio of ICT investment
to the aggregated investment in stock enhances the capital’s share of
income, and finally leads to income inequality such as the increase
of the share of the top decile income. Although we confirm the
positive relationship between ICT investment and income inequality,
the upward trend for that relationship depends on the values of
parameters for the making use of the simulations and these parameters
are not deterministic in the magnitudes on the calculated results for
the simulations.
Abstract: This study deals with wage inequality in organization
and shows the relationship between ICT and wage in organization.
To do so, we incorporate ICT’s factors in organization into our
model. ICT’s factors are efficiencies of Enterprise Resource
Planning (ERP), Computer Assisted Design/Computer Assisted
Manufacturing (CAD/CAM), and NETWORK. The improvement of
ICT’s factors decrease the learning cost to solve problem pertaining
to the hierarchy in organization. The improvement of NETWORK
increases the wage inequality within workers and decreases within
managers and entrepreneurs. The improvements of CAD/CAM and
ERP increases the wage inequality within all agent, and partially
increase it between the agents in hierarchy.
Abstract: This paper clarifies the role of ICT capital in economic
growth. Albeit ICT remarkably contributes to economic growth, there
are few studies on ICT capital in ICT sector from theoretical point of
view. In this paper, production function of ICT which is used as input
of intermediate good in final good and ICT sectors is incorporated
into our model. In this setting, we analyze the role of ICT on balance
growth path and show the possibility of general equilibrium solutions
for this model. Through the simulation of the equilibrium solutions,
we find that when ICT impacts on economy and economic growth
increases, it is necessary that increases of efficiency at ICT sector and
of accumulation of non-ICT and ICT capitals occur simultaneously.
