The moment conditions or estimating equations for instrumental variables quantile regression involves the discontinuous indicator function. We instead use smoothed estimating equations, with bandwidth h. This is known to allow higher-order expansions that justify bootstrap refinements for...

The literature has two types of fractional order statistics: an `ideal' (unobserved) type based on a beta distribution, and an observable type linearly interpolated between consecutive order statistics. We show convergence in distribution of the two types at an O(n-1) rate, which we also show...

We propose a nonparametric method to construct confidence intervals for quantile marginal effects (i.e., derivatives of the conditional quantile function). Under certain conditions, a quantile marginal effect equals a causal (structural) effect in a general nonseparable model, or equals an...

The literature has two types of fractional order statistics: an `ideal' (unobserved) type based on a beta distribution, and an observable type linearly interpolated between consecutive order statistics. From the nonparametric perspective of local smoothing, we examine inference on conditional...

Estimation of a sample quantile's variance requires estimation of the probability density at the quantile. The common quantile spacing method involves smoothing parameter m. When m, n → ∞ , the corresponding Studentized test statistic asymptotically follows a standard normal...

In this paper, we examine the relationship between the price level and output and the inflation rate and output at business-cycle frequencies. In the first part of the paper, we develop a methodological approach to characterizing joint business cycle correlations. In particular, we are...

Advance selling is a marketing strategy by a firm that allows consumers to submit pre-orders for a new to-be-released product. It helps the firm to reduce uncertainty about future demand and consumers to avoid stock-out risks. At the same time, consumers might be reluctant to place advance...

Economic experiments conducted in laboratories employing an induced-values methodology can report on allocative efficiencies observed. This methodology is limited by requiring the experimenter to know subjects' motivations, an impossibility in field experiments. Allocative efficiency implies a...

Previous research using data on convictions for corruption-related crimes from the Public Integrity Section (PIN) of the Department of Justice points to a positive correlation between the amount of corruption in a state and the amount of federal funds provided to the state for natural disaster...

This paper investigates the effects of estate taxation when firms cannot directly observe worker skill levels. Imperfect labor market signaling gives rise to an information externality that causes workers to free-ride off of others' human capital acquisition. Inherited wealth exacerbates the...
