This research stream aims to offer a new way of understanding the macroeconomic implications of market-shaping policies in terms of long-term investment and economic growth.
This research will build on the work of Professor Mariana Mazzucato and Dr. Matteo Deleidi on the macroeconomic effects of public investment in innovation and Dr. Josh Ryan-Collins’ work on the role of central banks and financial regulators in encouraging productive lending by the banking sector. To fully understand how effective the role of the public sector can be in fostering and influencing the direction of economic growth in the long run, it is fundamental to disentangle the channels through which public intervention can influence private investment.
For this reason, it becomes particularly relevant to have a robust empirical and theoretical analysis of the dynamic impact that different macroeconomic interventions have on the economy, including the effects on private investments.
The crucial questions that will be addressed are the following:
- Can expansionary fiscal policies generate positive and permanent effects on GDP?
- What size of economic multipliers associated with different types of fiscal policy, including directed public investment in innovation and mission-oriented policies as well as standard capital investment?
- Can fiscal policies ‘crowd-in’ private investment rather than crowd it out? If so, what types of policy are most effective?
- What is the role of private expectations on the interaction between state-funded innovation initiatives and firms’ investment in R&D?
- Under conditions of uncertainty about the future, what is the role of monetary policy and financial regulation in stimulating business investment and growth and how should monetary and fiscal policy be coordinated?
- What is the role of central banks and financial regulators in shaping financial markets to support innovation-led, sustainable growth?
To answer these questions, IIPP proposes a new theoretical framework that combines relevant insights from the literature on innovation (public and private) and industrial economics with the current debate in macroeconomics over the effects of different types of fiscal and monetary policies. The necessity for this new approach emerges from a twofold motivation: (i) to improve our understanding of the effects of fiscal and monetary policies on GDP growth and business investment; (ii) to assess the fundamental role that can be played by public policies in shaping and creating new markets and directions for technological advancements.
The motivation for such analysis arises from the Great Recession that followed the 2008 financial crisis, the current phase of economic stagnation, and the actual response that governments and central banks set out in terms of monetary and fiscal policies. In particular, the post-crisis response featured expansionary monetary policy combined with a restrictive fiscal policy, in the hope that an increase in the money supply and ensuing lower interest rates would be effective in fostering economic activity. Nevertheless, such policies have not generated the expected results for three main reasons: (i) a cut in public expenditures generates a permanent fall in GDP rather than an alleged expansion; (ii) an increase in money supply does not necessarily increase either the volume of private investment or the level of household consumption; (iii) low interest rates are ineffective in stimulating private enterprise and aggregate demand.
