For the past decade, the sharing economy has not only grown but also expanded to cover a wide variety of different activities across the globe. Despite a lot of research, there is still no agreement on how to define and measure the sharing economy, and no consensus on whether the sharing economy...

We provide empirical evidence that uncertainty (rather than risk) and optimism are distinctive characteristics of high-impact entrepreneurial firms (recently listed firms) relative to old, incumbent firms. Based on this evidence, we construct an entrepreneurial entry predation model with...

In this paper, we argue that fundamental reforms of the Swedish business sector can explain the remarkable productivity and employment growth that followed the deep economic crisis in Sweden in the early 1990s. In the 1970s and 1980s, Sweden had one of the most regulated business sectors in the...

We use a dynamic oligopoly model of entry and exit with store-type differentiation to evaluate how entry regulations affect profitability, market structure and welfare. Based on unique data for all retail food stores in Sweden, we estimate demand, recover variable profits, and estimate entry...

The policy debate in recent years has increasingly focused on issues concerning size distribution of firms and employment. It is often claimed that we are approaching a new economic era where large enterprises have lost their importance in developed economies. This raises the question of what we...

A government wanting to promote an efficient allocation of resources as measured by the total surplus, should strategically delegate to its competition authority a welfare standard with a bias in favour of consumers. A consumer bias means that some welfare increasing mergers will be blocked....

FDI can be an important channel for developing countries' ability to get access to new technology. The impact of FDI on domestically-owned firms' technology development is less examined but it is frequently argued that technology externalities or demonstration effects could have a positive...

This paper shows that the R&D intensity of an industry plays an important role in determining international trade patterns via its effect on scale economies. I first develop a model of trade with heterogeneous firms where firms compete with each other by spending on fixed product development...

This paper characterizes the Nash equilibrium in a pay-as-bid (discriminatory), divisible-good, procurement auction. Demand by the auctioneer is uncertain as in the supply function equilibrium model. A closed form expression is derived. Existence of an equilibrium is ensured if the hazard rate...

In most wholesale electricity markets generators must submit step-function offers of supply to a uniform price auction, and the market is cleared at the price of the most expensive offer needed to meet realised demand. Such markets can most elegantly be modelled as the pure-strategy, Nash...
