Should the Government Protect its Basic Research?

2017-08 , Cozzi, Guido , Galli, Silvia

Basic research is mainly performed publicly. Yet in the US public research findings were not patentable until 1980, and in other countries are not yet patentable. Patentability renders public research more directed, with less potential waste, but it also restricts private applied research. This paper shows, by means of a multi-stage Schumpeterian growth model, that in the long run the first effect is bound to dominate.

Will a Shrink Make you Richer? Gender Differences in the Effects of Psychotherapy on Labour Efficiency

2017-10-14 , Cozzi, Guido , Galli, Silvia , Mantovan, Noemi

This paper provides a first theoretical and empirical analysis of the effects of psychotherapy on individual productivity. We build a simple model in which a deterioration of mental health endogenously causes a decrease in productivity, which is counterbalanced by psychotherapy. We test our hypotheses on the British Household Panel Survey data. We find that individuals suffering from mental health problems benefit economically from consulting a psychotherapist. Moreover, we find that the returns are higher for men than for women, even though women are more likely to seek help.

Stories from the Frontier

2015 , Cozzi, Guido , Galli, Silvia

Should basic research be publicly or privately funded? This paper studies the impact of the shift in the U.S. patent system towards the patentability and commercialization of the basic R&D undertaken by universities during the early 1980s. We interpret this change as rendering universities responsive to "market" forces. Prior to 1980, universities undertook research using an exogenous stock of researchers motivated by "curiosity." After 1980, universities patent their research and behave as private firms. This move, in a context of two-stage inventions (basic and applied research) has an a priori ambiguous effect on innovation and welfare. We build a Schumpeterian model and match it to the data to assess this important turning point from an innovation as well from a welfare-enhancing perspective.

Counting Innovations: Schumpeterian Growth in Discrete Time

2019-11 , Cozzi, Guido , Galli, Silvia

Schumpeterian growth theory based on creative destruction was originally designed for continuous time innovation and growth models. However its recently expanding use in DSGE modelling calls for an easily usable discrete time recast. We here show how to construct a discrete time version of creative destruction fully equivalent to its continuous time counterpart.

Changing the Research Patenting Regime: Schumpeterian Explanation

2007 , Cozzi, Guido , Galli, Silvia

Starting in the early 1980s, the U.S. patent regime experienced major changes that allowed the patenting of numerous scientific findings lacking in current commercial applications. We assess the rationality of these changes in the legal and institutional environment for science and technology policy. In order to model these changes in the incentives for the commercialization of new ideas, we extend the standard multisector Schumpeterian growth theory by decomposing the product innovation into a two-stage uncertain research activity. This analytical structure, beside suggesting new sources of market and non-market failures, allows us to compare the general equilibrium innovative performance of an economy where early-stage scientific results are patentable with the general equilibrium innovative performance of an economic system where these earlystage results are unpatentable and freely disseminated by public research institutions such as the universities. If researchers are unguided by the invisible hand they risk to invent redundant half-ideas, but public universities are better at internalizing research externalities. When scientists can patent their research, monopolistic research firms restrict entry in the applied R&D. This makes a regime choice a priori controversial and dependent on the exogenous data on technologies. We calibrate the model to the US data and show that in the 70s, a relatively higher applied R&D complexity magni?ed the public basic R&D inefficiencies and justify the patentability of basic scientific findings.

Medium Frequencies in Non-Frontier Economies

2018-11 , Iordache-Bolboaca, Maria , Cozzi, Guido , Galli, Silvia

Most countries in the world are not at the technological frontier, yet their economies grow and fluctuate. In this paper we set up a model of endogenous growth with business cycle fluctuations usable to analyze the medium frequency fluctuations in non-frontier countries. The growth mechanism is a Schumpeterian creative destruction framework, which is embedded into a real business cycle dynamic stochastic general equilibrium model, with standard and non-standard features. We allow for multinational firms entering the economy and challenging existing incumbents, and study the tension between their direct positive productivity contribution and their indirect negative contribution through the expected obsolescence of domestic innovators. We calibrate the model and show, via simulations, the potential value added from our prototype model.
