This paper presents consideration of how the social security system evolves as the attributes of voters change. In our setting, policy determination is based on majority voting. The government has two components of social security policy: a pension system and unemployment insurance. When workers...

In analyzing economic policies, a severe problem is the time-inconsistency problem. In this regard, the choice of commitment vs. discretion engenders a tradeoff of flexibility and credibility. Therefore, it might be necessary and acceptable to adopt a discretionary policy to some degree, but...

This paper specifically examines intergenerational conflict and analyzes an overlapping generations model of public goods provision from the viewpoint of time-consistency. Public goods are financed through labor-income and capital-income taxation, thereby distorting savings and the labor supply....

This paper studies investment decisions by economic agents in cases where the tax rate is decided through voting. It will be shown that, in some cases, only a Pareto-dominated tax policy on the wrong side of the Laffer curve is supported under rational expectations. Thus, the governments may...

By using the panel data of 59 semiconductor companies in 2001-2013 this study investigates the characteristics of financial condition of each product segment and explores the effective product line policy in semiconductor industry. Semiconductor is well-known as one of the fundamental products...

We introduce into a Schumpeterian growth model an inventive step, which is a minimum innovation size required for patents, and thus a patentability requirement. We show that in order to satisfy an inventive step requirement, each R&D firm targets only industries in which the incumbentfs...

This study presents a two-period overlapping-generations model featuring en- dogenous growth and intergenerational conflict over fiscal policy. In particular, we characterize a Markov-perfect political equilibrium of the voting game between gen- erations, and show the following results. First,...

This paper develops a two-period overlapping-generations model featuring en- dogenous growth and intergenerational conflict over fiscal policy. In particular, the paper characterizes a Markov-perfect political equilibrium of the voting game be- tween generations, and shows the following results....

This study presents an overlapping generations model to capture the nature of the competition between generations regarding two redistribution policies, public education and public pensions. In addition, we investigate the effects of population aging on these policies and economic growth from a...

This study extends the multi-country, politico-economic model of fiscal policy developed by Song, Storesletten, and Zilibotti (2012) to incorporate wage inequality within each country. In this extended framework, we present conflict within and across generations over fiscal policy and show that...
