We introduce an infinite-horizon endogenous growth framework for studying the effects of foreign aid on the economic growth in a recipient country. Aid is used to partially finance the recipient's public investment. We point out that the same rule of aid may have very different outcomes,...

The paper introduces dividend taxation and productive government spending in an infinite-horizon general equilibrium model with heterogeneous agents and financial market imperfections. We point out that imposing a dividend tax and using the revenue from this tax to finance productive government...

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...

Despite being a mainstay of modern economic theory, the simple concept of arbitrage is sorely misused. In this paper we overview such instances, and offer an alternative definition. Most applications of arbitrage use it as a general equilibrating tendency irrespective of whether the outcome is...

We consider a leader who can choose between a transactional or a transformational style of leadership to motivate a team of followers, in presence of moral hazard and free riding. Transformational leadership extends transactional leadership by allowing the leader to deliver a motivational...
