We develop a dynamic two-party political economy framework, in which parties seek to maximize vote share and face the trade-off between catering to their respective core constituencies on the one hand and "middle of the road" voters with no partisan affiliation on the other hand. In contrast to...

This paper argues that openness to goods trade in combination with an unequal distribution of political power has been a major determinant of the comparatively slow development of resource- or land-abundant regions like South America and the Caribbean in the nineteenth century. We develop a...

Empirical evidence suggests that positive externalities from R&D exceed negative ones. According to conventional wisdom, this calls for R&D subsidies. This paper develops a quality-ladder growth model with overlapping generations which evaluates the positive and normative implications of R&D...

This paper demonstrates that the role of the personal income distribution for an economy's process of development fueled by human capital accumulation critically depends on the shape of the saving function. Empirical evidence for the U.S. strongly suggests that the marginal propensity to save is...

A positive relationship between firm size and product diversification is a long-standing stylized fact. However, so far there is no appropriate theoretical model to explain the underlying forces of this observation. This paper analyzes an oligopoly model with asymmetric multiproduct firms, which...

This paper develops a quality-ladder model of endogenous growth to study the interplay between in-house R&D and marketing expenditure. Although promotional activity is modelled as purely wasteful competition among firms for attention, it unambiguously fosters innovation activity of firms, and...

This paper develops a two-sector general equilibrium model in which firms in the primary economy have to create workplaces prior to production and product market competition. For this, we introduce the endogenous sunk cost approach with two-stage decisions of firms from IO in the macro-labor...

According to a standard argument, higher income inequality fosters redistributive activities of the government in favor of the median income earner. This paper shows that if redistribution is achieved by a public provision of goods and services rather than by transfers, higher income inequality...

In this paper, we develop a life cycle model in which health and longevity are threatened by infectious and chronic diseases. The model captures that the susceptibility and severity of infectious diseases depend on the accumulated health deficits (immunosenescence) and that the life history of...
