This study constructs a variety expansion growth model that integrates basic research to analytically examine its effects on household welfare. In our approach, the research sector consists of applied and basic research components. The former creates blueprints and expands the variety of goods available for consumption, whereas the latter adds to the stock of public knowledge. The two sectors interplay through knowledge spillovers. The analysis reveals two key results. First, the steady-state welfare-maximizing level of basic research is below the steady-state growth-maximizing level. Second, a reduction in the level of basic research raises household welfare if the level of basic research is initially at the steady-state welfare-maximizing level.
