This study examines the relationship between farm size and productivity in U.S. agriculture during 1982-92. A nonparametric regression method is applied to detect ex-post geographical patterns in changes in farm size and productivity. The estimations show that (i) in 1982 productivity per acre...

This paper adapts an already existing nonparametric hypothesis test to the bootstrap framework. The test utilizes the nonparametric kernel regression method to estimate a measure of distance between the models stated under the null hypothesis. The bootstraped version of the test allows to...

We present an econometric framework for robust pricing based on credible assumptions about consumer behavior. First, we introduce a panel data discrete choice model whose realistic assumptions about consumer behavior result in partial identification of preferences. Next we address the resulting...

We provide a first in-depth look at robust estimation of integrated quarticity (IQ) based on high frequency data. IQ is the key ingredient enabling inference about volatility and the presence of jumps in financial time series and is thus of considerable interest in applications. We document the...

Lee (2003) develops a n-consistent estimator of the parametric component of a partially linear quantile regression model, which is used to obtain his one-step semiparametric efficient estimator. As a result, how well the efficient estimator performs depends on the quality of the initial...

We construct a PCE-based price index whose weights minimize the welfare costs of nominal distortions: a cost-of-nominal-distortions index. We compute these weights in a multi-sector New Keynesian model, calibrated to match US data on price stickiness, labor shares, and inflation across sectors....

We use an innovative dataset (8 years with 2,057 firms) composed of Italian listed firms to analyze the network of women in boards, and to evaluate their effect on company value and performance. In particular, we use Social Network Analysis to analyze the growth of the female directorship...

This paper proposes a simple consistent nonparametric test of conditional symmetry based on the principle of characteristic functions. The test statistic is shown to be asymptotically normal under the null hypothesis of conditional symmetry and consistent against any conditional asymmetric...

European authorities and scholars published proposals on which indicators of macroeconomic imbalances might be used to uncover risks for the sustainability of public debt in the European Union. We test the ability of four proposed sets of indicators to send early-warnings of debt crises using a...

In this paper we are interested in investigating the effects of the threepart tariffs system on consumers’ behavior in the local fixed telephone service provided by the incumbent Telecommunications Company une in Medellín, which was authorized by the Telecommunications Regulatory Commission...
