Stock-Market Expectations: Econometric Evidence that Both REH and Behavioral Insights Matter
Roman Frydman,Joshua Stillwagon +1 more
TL;DR: In this paper, the authors present econometric evidence that fundamentals are a major driver of investors' expectations and that expectations are also in part extrapolative, this effect is transient.

Changing volatility of long-term UK interest rates during Pax Britannica
TL;DR: This article examined the stability of four long-term UK interest rates, including the yield on Consols, over a sample period spanning 1850-1914 and found that overall the interest rates did indeed exhibit remarkable stability over the long sample period.

Forward Speculation, Excess Returns, and Exchange Rate Variability: The Role of Risk Premiums
TL;DR: In this paper, the authors reconsiders the unbiasedness hypothesis in the foreign exchange market and estimates risk premiums for the dollar rates of the yen, mark, and pound using monthly data from the post-floating period.

Merger Laws, Globalization, and Corporate Value
Arturo Bris,Christos Cabolis +1 more
TL;DR: In this paper, the first attempt to isolate the direct effect of competition laws on a country's merger activity and indirectly on corporate value was made, and they found that although the direct relationship between merger laws and Tobin's Q is positive and significant, once they control for the net cross-border merger flows in a country, the relationship vanishes.

A Thresholding-Based Prewhitened Long-Run Variance Estimator and Its Dependence-Oracle Property
TL;DR: In this paper, a decision-based prewhitening filter is used to soak up the dependence of time series data and regularize autocorrelations of the resulting residual process by thresholding.

Consistent Covariance Matrix Estimation with Spatially Dependent Panel Data
John C. Driscoll,Aart Kraay +1 more
TL;DR: The authors presented conditions under which a simple extension of common nonparametric covariance matrix estimation techniques yields standard error estimates that are robust to very general forms of spatial and temporal dependence as the time dimension becomes large.

Assessing the Contribution of Venture Capital to Innovation
TL;DR: This paper examined the influence of venture capital on patent applications in twenty industries over three decades and found that increases in venture capital activity in an industry are associated with significantly higher patenting rates.

Approximately Normal Tests for Equal Predictive Accuracy in Nested Models
TL;DR: In this paper, the mean squared prediction error (MSPE) from the parsimonious model is adjusted to account for the noise in the large model's model. But, the adjustment is based on the nonstandard limiting distributions derived in Clark and McCracken (2001, 2005a) to argue that use of standard normal critical values will yield actual sizes close to, but a little less than, nominal size.

Tests of Conditional Predictive Ability
TL;DR: This paper proposed a framework for out-of-sample predictive ability testing and forecast selection designed for use in the realistic situation in which the forecasting model is possibly misspecified, due to unmodeled dynamics, unmodelled heterogeneity, incorrect functional form, or any combination of these.
