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...

Whether or not banks are engaged in ex ante monitoring of customers may have important consequences for the whole economy.We approach this question via a model in which banks can invest in either information acquisition or market power (product differentiation). The two alternatives generate...

We study a financial market adverse selection model where all agents are endowed with initial wealth and choose to invest as entrepreneurs or financiers, or not to invest.We show that often a lack of outside finance leads to the emergence of financial markets where availability of outside...

This paper studies the welfare effects of R&D subsidies. We develop a model of continuous optimal treatment with outcome heterogeneity where the treatment outcome depends on applicant investment. The model takes into account heterogeneous application costs and identifies the treatment effect on...

We extend the theoretical basis of the empirical literature on the effects of R&D subsidies by providing an estimable model of strategic interaction among subsidy applicants, and public and private sector R&D financiers. Our model incorporates fixed R&D costs and a cost of external finance. We...

We conduct a welfare analysis of R&D subsidies and tax credits using a model of innovation policy in corporating externalities, limited R&D participation and finanial market imperfetions. We estimate the model using R&D projet level data from Finland. The optimal R&D tax credit rate (0.24) is...
