A measure of total factor productivity with biased technological change

The paper presents a new measure of total factor productivity (TFP) that also takes into account the effect of biased technological change. With this methodology, we can distinguish the effects resulting from the introduction of neutral or biased technological change on TFP, called neutral factor productivity and biased factor productivity (BFP), respectively. The new measure of TFP also holds in extreme cases where only the effect of neutral/biased technological change is presented. In particular, the BFP component increases (decreases) when the productivity of the cheaper (more expensive) factor increases. Moreover, the TFP holds up to the modification of both units of measure and to the costs of factors. Finally, the intensity of the BFP is independent of the direction of the technological change.     

Entrepreneurship and the systemic consequences of epidemics: A literature review and emerging model

The Covid-19 epidemic is a global challenge requiring adequate public and private responses to overcome the emergency, shape new development trajectories, and prepare for future outbreaks. As socioeconomic turning points, epidemics imply an entrepreneurial response in which not only managers and entrepreneurs, but also policymakers, health professionals, and civil society as a whole are active participants. Using the PRISMA methodology, we provide a comprehensive review of the complex interactions between entrepreneurship and epidemics over time. Applying a combined Kirznerian-Schumpeterian theoretical framework, we find that, in the short term, epidemics trigger a wave of Kirznerian entrepreneurship aimed at reducing the uncertainty generated directly and indirectly by the medical emergency. In the long term, as medical uncertainty abates, Schumpeterian entrepreneurship can contribute to transforming the post-crisis environment, either supporting or undermining the public reaction to the crisis and determining the path of institutionalization, in the process of defining a new normal. Thus, epidemics could lead to unpredictable socioeconomic and technological improvements, but also to highly undesirable outcomes. The construction of a satisfactory new normal requires the integration of entrepreneurial capabilities within the public sector and an explicit policy of cooperation with the private sector. Therefore, as the short-term phase of the Covid-19 pandemic draws to a close, policymakers must shift their focus away from restrictions and obligations towards a collaborative framework supportive of private entrepreneurial efforts.
