Neoclassical economic thinkers developed the idea of business cycles: alternating peaks and troughs of economic expansion and contraction. Recessions, they argued, start at the peak of the cycle and end at the bottom of the trough, which is when the next period of expansion begins. Today, we ...
We develop a model for economic growth applicable to a group of countries, constituting around half of the gross global production, that have been consistently “catching up” to the US since 1960 or so. This group can be termed “the convergence club.” The model has a theoretical basis de...
The paper cites the example of the Baltic Sea Region which has experienced decades of fertilizer overuse (1950s–1990s) and concomitant urban sources of excessive nutrients. Regulations and incentive policies combining the nitrogen, phosphorus and carbon cycles are necessary if circular nutrient ...

Two important considerations of any firm are its level of profitability and whether to continue to operate in the current environment. Theopportunity cost (economic cost )of any particular decision, such as to produce a given level of output, can be determined by measuring the benefit forgone by...
As such, they represent a critical link for energy and matter transfer between phytoplankton and bacterioplankton to higher trophic levels and play an important role in global biogeochemical cycles. In this Review, we discuss key responses of zooplankton to ocean warming, including shifts in phenology...
The funnel chart analysis method is a management analysis tool suitable for comparing and standardizing business processes with long cycles and involving complex business processes.For example, funnel charts are used for analyzing conversion rates of certain key pathways on websites. They not only displ...
From the perspective of innovation studies, however, there remains a need for an explicit measure of the technological capabilities of nations. Can the missing link between product groups and technology (patent) portfolios be endogenized into the model (Nelson and Winter, 1977, Nelson and Winter...
A thermodynamic model of the system process was developed and used to comprehensively assessment of the performance in terms of thermodynamic, CO2 reduction potential, and economic. The results indicate a net electrical efficiency of 50.41%, a net electrical output of 9124.5 kW, a CHP efficiency ...
