Hartwick’s rule says that as mineral resources are extracted from the ground, investments in productive assets need to be made to leave future generations with as much assets as the present generation. This article examines whether mining in Goa meets Hartwick’s rule, and finds that the...

We present some theoretical frameworks used in macroeconomics, mainly economic growth. Our goal is not to provide a unified model but rather to present simplified versions of models in the classic academic articles to help students familiarize with theoretical models used in macroeconomics and...

This research explores the origins of the distribution of time preference across regions. It advances the hypothesis, and establishes empirically that geographical variations in the natural return to agricultural investment have had a persistent effect on the distribution of time preference...

This research explores the origins of observed differences in time preference across countries and regions. Exploiting a natural experiment associated with the expansion of suitable crops for cultivation in the course of the Columbian Exchange, the research establishes that pre-industrial...

By assuming that the individual derives utility from consumption only, the resulting optimal decision to save in the Ramsey model depends on the rate of return, given a certain time preference. If therefore the production function is such that this rate of return remains relatively low, the...

We study an economy in which the rate of change of population depends on population policy decisions. This requires population as well as capital as state variables. By showing the algebraic relationship between the shadow price of the population and the shadow price of the per capita capital...

In a demand-side growth model, we show that a developing economy may experience a steady positive equilibrium growth rate of investment and profit- as long as investment in the economy is responsive to the aspirations of the richer section of the population to match the consumption level of the...

Despite ‘joy of giving models’ have been extensively examined in the literature, the Ramsey growth model has never been explored under the assumption of a direct preference for bequeathing savings that are reinvested. This assumption implies a Utility function depending on both consumption...
