This paper studies the macroeconomic implications of firm-branding activities. We show empirically that firms build market share by creating new brands, developing their existing brands, and buying established brands from other firms. Sales and prices of the underlying branded products tend to...

During the Great Moderation, macroeconomic volatility declined while firm markups increased. We document a causal relationship between volatility and markups due to tacit collusion. We exploit the legalisation of interstate banking as an exogenous decrease in volatility. Using an instrumental...

This paper estimates a dynamic general equilibrium model of entry, exit, and endogenous productivity growth. Productivity is endogenous both at the industry level (firms enter and exit) and at the firm level (firms invest in productivity-enhancing activities). The focus of the paper is on two...

In contrast to the very large literature on skill-biased technical change among workers, there is hardly any work on the importance of skills for the entrepreneurs who employ those workers, and in particular on their evolution over time. This paper proposes a simple theory of skill-biased change...

This paper quantifies the determinants of heterogeneity in R&D investment and its implications for growth. Using a panel of Norwegian manufacturing firms we document a negative correlation between R&D intensity and firm size, driven mainly by small firms with high R&D intensity. We estimate a...

This paper extends the Lucas (1978) model of firm formation by taking into account a normalised CES function in the production process. In a general equilibrium framework it is proved that there is an inverse relation between the value of the elasticity of substitution and average firm size....

The aim of the present short paper is to show that since the 1970s the world has changed considerably, and that this change has had consequences for the current policy debate on the determinants of economic growth. Our paper deals with some aspects of the recent scientific literature on the...

We build a novel dynamic model of two-sided markets which can be used to explore both intertemporal and cross-side pricing strategies of platform enterprise. This two-period model goes beyond the traditional two-sided market framework to examine the new intertemporal tradeoffs that a platform...

I develop a simple Schumpeterian agent-based model where industries are born and evolve endogenously and use it to study the interrelation between technological change, economic growth, market concentration and inequality. This theoretical model combines features from the Schumpeter Mark I...
