In this paper, we introduce into a Schumpeterian growth model an inventive step: a minimum innovation size required for patents, which is a patentability requirement. We show that each R&D firm targets only the industries that the incumbentfs technology is sufficiently obsolete in order to...

An overlapping generations model with the double infinity of commodities and agents is the most fundamental framework to introduce outside money into a static economic model. In this model, competitive equilibria may not necessarily be Pareto-optimal. Although Samuelson (1958) emphasized the...

We consider a two-period overlapping generations model where agents face the uncertainty of intergenerational transfers from their children. To avoid this kind of risk, agents have an incentive to share the risk within the same generation. However, there exists an information asymmetry about the...

In this paper, we investigate causal relationships among exports, imports, and economic growth in North Korea by using time series data for the period between 1964 and 2004. The empirical results show that there was Granger causality from imports to GNP in the first half of the period. However,...
