This Element combines the advances of the economics of knowledge and innovation implementing the Schumpeterian notion of creative response to understand the determinants and the effects of the rate and direction of technological and organisational change and its variance across time and space,...

In this paper we extend the tests of the monotonicity and concavity of a non-spatial translog production function to the case where there is spatial autoregressive dependence. The tests are then applied using data for 40 European countries over the period 1995-2008

Economists often model the delicate relationship between production, innovation, and economic growth as a production function that exhibits increasing returns to scale (IRS). The existence of "knowledge spillovers" or "learning by doing" often implies conclusions about the optimal use of...

We study potential impacts of future climate change on U.S. agricultural productivity using county-level yield and weather data from 1950 to 2015. To account for adaptation of production to different weather conditions, it is crucial to allow for both spacial and temporal variation in the...

This study provides a guideline for dealing with endogenous inputs and environmental variables in Battese and Coelli's (1995) stochastic frontier model, which has been used in a vast number of empirical studies. The presence of endogenous variables in Battese and Coelli's model leads to...

Freemium products must attract a disproportionately large user base to capture value, but they are often “hit or miss”. Which freemium products are best positioned to becoming a killer app, and under what conditions? Drawing on freemium's distinguishing features of low adoption barriers and...
