This paper proposes an alternative to the classical price-adjustment mechanism (called "t\^{a}tonnement" after Walras) that is second-order in time. The proposed mechanism, an analogue to the damped harmonic oscillator, provides a dynamic equilibration process that depends only on local...

In two previous papers the author developed a second-order price adjustment (t\^atonnement) process. This paper extends the approach to include both quantity and price adjustments. We demonstrate three results: a analogue to physical energy, called "activity" arises naturally in the model, and...

General equilibrium is the dominant theoretical framework for economic policy analysis at the level of the whole economy. In practice, general equilibrium treats economies as being always in equilibrium, albeit in a sequence of equilibria as driven by external changes in parameters. This view is...

Scaling relations, such as the IPAT equation and the Kaya identity, are useful for quickly gauging the scale of economic, technological, and demographic changes required to reduce environmental impacts and pressures; in the case of the Kaya identity, the environmental pressure is greenhouse gas...

In the face of increasingly likely dangerous climate change, many developing countries are designing green economy or low-emissions development strategies, but are simultaneously on a course of investment locking them into high-emission infrastructure. Meanwhile, many high-income countries are...

Kaleckian models are widely used for macroeconomic analysis due to their flexibility and simplicity. Sraffians counter that the Kaleckian model fails to capture a central fact of modern economies, the existence and importance of intermediate consumption. The critique is correct, but as the...

In the (very) long run, a sustainable economy must rely on renewable resources. Until that time, an economy can be based on either renewable resources alone or a mix of renewable and non-renewable resources, but the particular mix may constrain the types of economic structures that are possible....

The National Bioenergy Investment Model is a scenario model that simulates the decisions of domestic and international investors on whether to invest in biofuel enterprises in a developing country. In the model, investors compare the profitability of different biofuel feedstock and fuel...

This paper provides an explication of the Method of Reflections developed by Hidalgo and Hausmann and a critique of their interpretation of the variables that it produces. They show that a quantity they identify with the average complexity of a country’s exports is correlated with log income....

A central conclusion of the standard theory of consumption is that consumers' preferences can be taken as theoretical primitives. Special categories of consumption, such as "basic needs", or of goods, such as "subsistence goods" are seen as extra theoretical baggage that add few, if any,...
