Computation of equilibria in heterogeneous agent models
This paper essentially puts together procedures that are used in the computation of equilibria in models with a very large number of heterogeneous agents. It is not a complete description of all procedures used in the literature. It describes procedures that deal with infinitely lived agent versions of the growth model with and without aggregate uncertainty, overlapping generations models, and dynamic political economy models.Econometric models
The Balance of Payments and Borrowing Constraints: An Alternative View of the Mexican Crisis
In standard models of the balance of payments, crises occur when investors begin to doubt the credibility of the government's commitment to its exchange rate policy. In this paper, we develop an alternative model in which balance of payments crises occur even if the credibility of government fiscal, monetary, and exchange rate policies is never in doubt. In this alternative model, international lending is constrained by the risk of repudiation. Balance of payments crises occur when the government and citizens of a country hit their international borrowing constraints. Our model is broadly consistent with events in Mexico from 1987-1995. More generally, our model suggests that countries which undertake sweeping macroeconomic and structural reforms should expect to face a balance of payments crisis when they exhaust their access to international capital inflows.
The balance of payments and borrowing constraints: an alternative view of the Mexican crisis
In this paper we develop a model in which a country faces a balance of payments crisis if constraints on its international borrowing bind. We use the model to describe the dynamics of the trade balance, capital account, and balance of payments of a country that borrows to finance consumption following sweeping macroeconomic and structural reforms and then hits constraints on its international borrowing. We compare the predictions of this theoretical example with events in Mexico from 1987 through 1995.Financial crises - Mexico ; Balance of payments ; Mexico

Idiopathic Bilateral Internal Jugular Vein Thrombosis Diagnosed by Point-of-Care Ultrasound
Internal jugular vein (IJV) thrombosis is an unusual condition, especially when it develops bilaterally. This is a case of bilateral IJV thrombosis in a 77-year old female who presented to the emergency department with neck and arm swelling after discontinuing apixaban and undergoing an oropharyngeal procedure. The diagnosis of bilateral IJV thrombosis was made with the use of point-of-care ultrasound to evaluate bilateral jugular vein distention and bilateral upper extremity pitting edema found on her physical examination
Life insurance and household consumption.
In this paper, we use data of life insurance holdings by age, sex, and marital status to infer how individuals value consumption in different demographic stages. Essentially, we use revealed preference to estimate equivalence scales and altruism simultaneously in the context of a fully specified model with agents facing U.S. demographic features and with access to savings markets and life insurance markets. Our findings indicate that individuals are very caring for their dependents, that there are large economies of scale in consumption, that children are costly but wives with children produce a lot of goods in the home and that while females seem to have some form of habits created by marriage, men do not. These findings contrast sharply with the standard notions of equivalence scales.Insurance
