``Limits of Arbitrage" theories require that the marginal investor in a particular asset market be a specialized arbitrageur. Then the constraints faced by this arbitrageur (i.e. capital constraints) feed through into asset prices. We examine the mortgage-backed securities (MBS) market in this...

We study how heterogeneous beliefs affect returns and examine whether heterogeneous beliefs are a priced factor in traditional asset pricing models. To accomplish this task, we suggest new empirical measures based on the disagreement among analysts about expected (short-term and long-term)...

Most investors purchase securities knowing they will resell those securities in the future. Uncertainty about the preferences of future trading counter-parties causes randomness in future resale prices that we call liquidity risk. It is natural to suppose that investors are asymmetrically...

This paper examines the long-run dynamics and the cyclical structure of the US stock market using fractional integration techniques. We implement a version of the tests of Robinson (1994a), which enables one to consider unit (or fractional) roots both at the zero (long-run) and at the cyclical...

Promising emerging equity markets often witness investment herds and frenzies, accompanied by an abundance of media coverage. Complementarity in information acquisition can explain these anomalies. Because information has a high fixed cost of production, its equilibrium price is low when...

Foreign Direct Investment has become an important source of long-term capital inflows for less developed countries in the last two decades. As documented in previous literature, FDI flows may increase permanently domestic output and represent an important source of technological spillovers for...

This paper considers measures of uncertainty used in economic estimation. Our first contribution is to address the theoretical relationship between cross-section and time series measures, highlighting the reasons why these might diverge. In a subsequent empirical section, we compare measures of...

We use a novel data set and identification strategy to empirically detect the presence and magnitude of local social interactions effects in the labor market. We argue that the use of informal referrals has implications for the spatial distribution of residential and work locations, that can...

This paper is concerned with estimating the additive components of a nonparametric additive quantile regression model. We develop an estimator that is asymptotically normally distributed with a rate of convergence in probability of $n^{-r/(2r+1)}$ when the additive components are $r$-times...

In this paper, we are interested in a stochastic frontier model in which observable characteristics of the firms affect their levels of technical inefficiency. Let u ≥ 0 be the one-sided error reflecting technical inefficiency, and let z be a set of variables that affect u. We write u as...
