International student exchange has become an important part of university-level studies and the EU plans to increase it significantly. We analyze how international student exchange affects students' academic human capital. Using detailed student-level data from four faculties (Economics and...

We construct a model of innovation incorporating R&D externalities, R&D participation, financial market imperfections, and application and allocation of R&D subsidies, estimate it using Finnish R&D project level data and conduct a welfare analysis. The intensive, not the extensive R&D margin is...

In this article we review recent evidence showing how market forces and policies shape the rate and direction of innovation, with various implications for inequality. First, we characterize several market mechanisms whereby higher rates of innovation lead to higher inequality. Second, we...

In this paper we study a horizontally differentiated market for financial in-termediation and develop a simple explanation for concentration in the financial intermediation industry. We show that under asymmetric information, if the demand for funds is not perfectly elastic, the heterogeneity of...

In many industries, including telecommunications, a government decision on a standard is needed for the society to reap the benefits from the diffusion of new goods. Delays induced by regulatory bodies either in standard choice or its implementation can be extremely costly. I study...

Mobile phones are increasingly used as a gateway to the Internet. The take-up of mobile phone-enabled Internet services was, however, initially slower than expected, at least in Europe. We estimate non-parametrically the price elasticities of demand for first-generation wireless services using...

This paper provides evidence that capital market imperfections hold back innovation and growth, and that public policy can complement capital markets. We deliver the evidence by studying the effects of government funding on the behavior of SMEs in Finland. By adapting the methodology recently...

We study empirically the determinants of deposit supply using bank level data from local Finnish cooperative banks. Of special interest is the effect of bank branch density on deposit supply. Our main finding is that holding other things constant, the denser the branch network, the lower the...

In a model of bank lending characterized by asymmetric information, we show that banks may misuse the availability of an interim monitoring technology to soften price competition, even though the borrowers face no moral hazard problem. The interim monitoring technology can also be used to...

Many new technologies exhibit clear generational changes. The empirical literature on technology diffusion traditionally analyses the spread of new technologies generically. We use data from the mobile phone industry, where first-generation (1G) and second-generation technologies (2G) can be...
