In this paper, we design a theoretical model to analyze the impact of the number of firms on investment in the wireless communications industry. Our model extends the Salop's framework by introducing investment in quality that either reduces the marginal cost of production or shifts the...

We examine product and market entry choices of New Zealand exporters, using an enterprise level dataset which links firm performance measures with detailed data on merchandise trade. We focus our enquiry not on the broad question of what determines a firm's ability to export, but on the...

This paper develops a search and matching model with hierarchical firms, human capital accumulation, internal promotions and on-the-job search. At the time of their market entry firms maximize present value of profits with respect to their promotion rule. Workers who are eligible for promotion...

We study optimal subsidies for renewable energy (RE) generation to internalize external benefits from intertemporal learning-by-doing spillovers, taking into account increasing marginal costs at the industry level due to limited availability of sites suitable for RE. We find that the optimal RE...

Empirical studies show that women are under-represented in highly paid top management positions of firms (glass-ceiling effect) which could be a cause of the gender wage gap. In order to study women's career paths, we develop a search and matching model where job ladders consist of three...

From the viewpoint of an innovator a patent is a tradeoff between the right to exclude others from using the patented matter versus the requirement to disclose it. Given the sequential nature of many innovations, patent induced technology diffusion can spur technological progress. However,...

We study optimal promotion decisions of hierarchical firms, with one junior and one senior managerial position, which interact in a search and matching labour market. Workers acquire experience over time while being employed in a junior position and the firm has to determine the experience level...

Carbon pricing policies worldwide are increasingly coupled with direct or indirect subsidies for emission-intensive and trade-exposed firms. We analyze the incentives created by novel forms of emissions intensity-based rebating (IBR) and contrast them with more common approaches like...

I analyse firms organisational choices when they face uncertainty about institutional conditions in foreign locations with heterogeneous final good producers and incomplete contracts. As firms learn about the conditions abroad, the increasing offshoring activity increases competition in the...
