We present a new jackknife estimator for instrumental variable inference with unknown heteroskedasticity. It weighs observations such that many-instruments consistency is guaranteed while the signal component in the data is maintained. We show that this results in a smaller signal component in...

Modeling and detecting parameter stability of econometric models is a long standing problem. Most existing estimation and testing methods are designed for models without endogeneity. Little attention has been paid to models with endogeneous regressors, which may arise in many scenarios in...

In this paper we use novel historical data on economics and social rights from the constitutions of 201 countries and an instrument variable strategy to answer two important questions. First, do economic and social rights provisions in constitutions reduce poverty? Second, does the strength of...

This paper offers the first instrumental variables estimates of the wage returns to volunteer experience. The returns are substantial and differ considerably by gender. The results imply that the unequal valuation of volunteer experience by gender is more important in explaining the gender...

This paper presents the impact evaluation of CRIAR program, implemented in rural areas in Bolivia. The objective of CRIAR is to increase smallholders' agricultural income and food security through productivity improvements triggered by technological adoption. In this study, we use data from a...

This article examines the effect of a change in stock market trading volume on employment in the New York City securities industry. This relationship is used as the first stage in an instrumental variables model to determine the effect that securities employment has on other forms of employment...

Research on civil conflict focuses primarily on identifying underlying and proximate causes while leaving many questions of subsequent social consequences unanswered. Few studies have systematically examined how these conflicts affect public opinion, especially tolerance attitudes. Additionally,...

Research shows that structural holes and network connectivity are associated with entrepreneurial performance. Yet the explanatory variables will tend to be correlated, and multicollinearity may skew the results. The use of instrumental variables can nevertheless generate reliable estimates. The...

Reuveny and Keshk (“Reconsidering trade and conflict simultaneity: The risk of emphasizing technique over substance,†this issue, 2013) argue that the econometric techniques used by Goenner (Conflict Management and Peace Science 28(5): 459–477, 2011) to test and control for...

We examine the impact of banks’ exposure to market liquidity shocks through wholesale funding on their supply of credit during the financial crisis in the United States. We focus on mortgage lending to minimize the impact of confounding demand factors that could potentially be large when...
