We explore the limitations of the adaptationist view of evolution and propose an alternative. While gradual adaptation can explain some biological and economic diversity, it cannot account for radical innovation (especially during the past 10,000 years). We argue that ubiquitously available but...

In this paper we test the AK model of growth with laboratory experiments. In each period, agents produce and trade output in a market, and allocate it to consumption and investment. The economy should experience a constant and positive rate of growth. We analyze two treatments differing from...

We propose an agent-based computational model defining the following dimensions of structural change - organisation of production, technology of production, and product on the supply side, and income distribution and consumption patterns on the demand side - at the microeconomic level. We define...

The Lucas (1978) Tree Model lies at the heart of modern macro-finance. At its core, it provides an analysis of the equilibrium price of a long-lived asset in an exchange economy where consumption is the objective, and the sole purpose of the asset is to smooth consumption through time....

Today 2.6 billion people in developing countries rely on biomass as primary cooking fuel, with profound negative implications for their well-being. Improved biomass cooking stoves are alleged to counteract these adverse effects. This paper evaluates take-up and impacts of low-cost improved...
