Given data on a scalar random variable 𝑌, a prediction set for 𝑌 with miscoverage level 𝛼 is a set of values for 𝑌 that contains a randomly drawn 𝑌 with probability 1 - 𝛼, where 𝛼 ∈ (0, 1). Among all prediction sets that satisfy this coverage property, the oracle...

I prove that in any linearized general equilibrium model with existence and uniqueness of equilibrium, any present response to a future shock always becomes weaker the further away the shock is. There is no forward guidance puzzle in any sensible general equilibrium model if forward guidance is...

In this paper, we advance the network theory of aging and mortality by developing a causal mathematical model for the mortality rate. First, we show that in large networks, where health deficits accumulate at nodes representing health indicators, the modeling of network evolution with Poisson...

Interest in the topic of well-being has burgeoned in recent years as the weaknesses of gross domestic product (GDP) per capita as a proxy for well-being have become more apparent. At the same time, the global economy has experienced a productivity slowdown. Since productivity growth is...

I provide a framework for understanding debt deleveraging in a group of _nancially integrated countries. During an episode of international deleveraging world consumption demand is depressed and the world interest rate is low, reecting a high propensity to save. If exchange rates are allowed to...

I develop a model where governments might prefer to have an undercapitalized domestic financial sector during crises. Weak banks optimally tilt their sovereign bond portfolio towards domestic securities that are positively correlated with banks' other sources of revenues. Governments anticipate...

In statistics, samples are drawn from a population in a datagenerating process (DGP). Standard errors measure the uncertainty in sample estimates of population parameters. In science, evidence is generated to test hypotheses in an evidencegenerating process (EGP). We claim that EGP variation...

A growing literature uses now widely available data on beliefs and expectations in the estimation of structural models. In this chapter, we review this literature, with an emphasis on models of individual and household behavior. We first show how expectations data have been used to relax strong...

African countries have over the years experienced persistent current account deficits. The role of asymmetries in explaining the response of trade balance to exchange rate movement has not received adequate attention as linear models dominate extant empirical literature. In this paper, we...

The convex time budget (CTB) method is a widely used experimental method for eliciting an individual's time preference. Researchers adopting the CTB experiment usually assume quasi-hyperbolic discounting utility as a behavioural model and estimate the parameters of the utility function. However,...
