Sacred Ecology: The Environmental Impact of African Traditional Religions

Do religions codify ecological principles? This paper explores theoretically and empirically the role religious beliefs play in shaping environmental interactions. We study African Traditional Religions (ATR) which place forests within a sacred …

Quickest Detection of Ecological Regimes for Natural Resource Management (R&R)

We study the stochastic dynamics of a renewable resource harvested by a monopolist where harvesting affects the resource’s potential to regenerate, resulting in sequential regime shifts.

Religiously-Inspired Baby Boom: A Case Study of Georgia (R&R)

We study the persuasive impacts of religious authority figures on fertility decisions. We do so in the context of Georgia where in December 2007, in a move to boost the declining fertility rates, the Georgian Orthodox Church's Patriarch began to …

Firm Decisions under Jump-Diffusive Dynamics

We present a model of firm investment under uncertainty and partial irreversibility in which uncertainty is represented by a jump diffusion. This allows to represent both the continuous Gaussian volatility and the discontinuous uncertainty related to information arrival, sudden changes and large shocks. The model shows how both sources of uncertainty negatively impact the optimal investment and disinvestment policies, and how the presence of large negative jumps can drastically affect the firm's ability to recover. Our results show that the standard Gaussian framework consistently underestimates the negative effect of uncertainty on firm investment decisions. We test these predictions on a panel of UK firms - we first structurally estimate the uncertainty parameters using multinomial maximum likelihood and differential evolution techniques and subsequently study their impact on firm investment rates, validating our model predictions.
