This paper develops a network economy model to study the propagation of the COVID lockdown shock. Firms are related to each other through buyer-seller relations in the market for intermediate inputs. Firms choose production levels and input combinations using prices that emerge from local...

This paper estimates the cost of the lockdown of some sectors of the world economy in the wake of COVID-19. We develop a multi sector disequilibrium model with buyer- seller relations between agents located in different countries. The production network model allows us to study not only the...

The process of electricity production, distribution, and consumption represents a complex system with many heterogeneous characteristics. Physical constraints of the electricity, especially the difficulties with its storage, pose specific challenges on the structure of the power network and the...

We develop an additive Cox proportional hazard model with time-varying covariates, including spatio-temporal characteristics of weather events, to study the impact of weather extremes (heavy rains and tropical cyclones) on the probability of mortgage default and prepayment. We estimate the model...

In the wake of the COVID-19 pandemic, the Government of India imposed production restrictions on various sectors of the economy. Prima facia there is reason to believe that the cost of the quantity constraints may be greater than their simple sum. This is because quantity constraints percolate...
