The extent to which firms respond to labor supply shocks has important implications for local and national economies. We exploit firm-level panel data on product and process innovation activities in the United Kingdom and find that the large, low-skill labor supply (immigration) shock generated...

Diversity of a country is often measured by the amount and spread of nationalities that live there. But also within a country, regions vary in their traditions and culture. Cultural homogeneity within communities is mixed up by (internal) migration, that, like international migration, increases...

The economic consequences of migration are hotly debated and a main topic of recent populist movements across Europe. We analyze Polish immigration in the context of the 2004 enlargement of the European Union and find a positive and significant spillover effect of the immigrants on the number of...

We address the notion of dynamic, endogenous diversity and its role in theories of investment and technological innovation. We develop a formal model of an innovation arising from the combination of two existing modules with the objective to optimize the net benefits of diversity. The model...

This paper extends the existing literature on strategic R&D alliances by presenting a model of innovation networks with endogenous absorptive capacity. The networks emerge as a result of bilateral cooperation over time between firms occupying different locations in the knowledge space. Social...

In case of a product innovation firms start producing a new product. While doing so, such a firm should decide what to do with its existing product after the firm has innovated. Essentially it can choose between replacing the established product by the new one, or keep on producing the...

In this paper we analyze an inter-temporal optimization problem of a representative firm that invests in horizontal and vertical innovations and that faces a constraint with respect to total R&D spending. We find that there can exist two different steady-states of the economy when the amount of...

The purpose of this paper is to define innovation and to proffer evidence of its existence through the use of statistical method and mathematical modeling. Innovation is defined by the confidence interval of the normal probability distribution density where μ ± 2σ = 0.95 leaving a room of...

Does the emigration of skilled individuals necessarily result in losses for source countries due to the brain drain? Combining industry-level patenting and migration data from 32 European countries, we show that emigration in fact positively contributes to innovation in source countries. We use...
