Adaptive Market Hypothesis and Predictability: Evidence in Latin American Stock Indices

Latin American Research Review
This article examines the adaptive market hypothesis in the five most important Latin American stock indices. To that end, we apply three versions of the variance ratio test, as well as the Brock-Dechert-Scheinkman test for nonlinear predictability ...

Stop Using Limiting Stimuli as a Measure of Sensitivities of Energetic Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Accurately estimating the sensitivity of explosive materials is a potentially life‐saving task that requires standardised protocols across nations. One of the most widely applied procedures worldwide is the so‐called ‘1‐In‐6’ test from the United Nations (UN) Manual of Tests in Criteria, which estimates a ‘limiting stimulus’ for a material. In

Deepening the real options debate: Real options as dynamic optimization

Strategic Management Journal, EarlyView.
Abstract Research Summary Is real option theory useful for management research? This topic was hotly debated two decades ago. Real options were said to be inapplicable to management research and to lack conceptual distinctiveness. Whereas responses to the claim about the non‐distinctiveness of real options were disparate, the concern about the theory's

Who Moves First? Price Discovery by Institutional and Retail Investors

Accounting &Finance, EarlyView.
ABSTRACT This paper uses 77 million Finnish trades, classified as foreign institutional or domestic retail, to examine the drivers of price discovery. The results show that foreign institutional investors dominate price discovery overall, including during the Global Financial Crisis. Their informational advantage is explained by buy‐ and sell‐initiated

Idiosyncratic asset return and wage risk of US households

Economic Inquiry, Volume 63, Issue 2, Page 636-657, April 2025.
Abstract This paper documents the degree of idiosyncratic asset return heterogeneity, serial correlation, and correlation with wage heterogeneity for US households. Novel panel‐data measurements for returns on household assets are proposed. Sizable transitory idiosyncratic return heterogeneity is documented to exist concurrently with permanent ...

ON THE TESTING MULTI-VALUED MARTINGALE DIFFERENCE HYPOTHESIS

Journal of Computer Science and Cybernetics, 2018
This paper presents a definition of Multi-Valued Martingale Difference (MVMD) based on Castaing representation of a multi-valued martingale that consists of martingale difference selections. Testing the Multi-Valued Martingale Difference Hypothesis (MVMDH) then examined.

Learning in the Limit: Income Inference from Credit Extensions

The Journal of Finance, EarlyView.
ABSTRACT Combining a randomized controlled trial with administrative and survey data, this paper shows that credit limit extensions significantly increase total spending and income expectations. By controlling for changes in personal income expectations, the spending response to credit limit extensions weakens by approximately 30%.

Estimation of the Intercept Parameter in Integrated Galton–Watson Processes

Journal of Time Series Analysis, EarlyView.
ABSTRACT We study the estimation of the intercept parameter in an integrated Galton–Watson process, an important building block for many count‐valued time series models. In this unit root setting, the ordinary least squares estimator is known to be inconsistent, whereas the existing weighted least squares (WLS) estimator is consistent only in the case ...

Testing for Rough Volatility When Prices Are Purely Discontinuous

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of nonparametric testing for rough volatility, using high‐frequency data with a fixed time span, in a setting where the price is purely discontinuous. More specifically, we analyze the asymptotic properties of a test we developed in previous work in a pure‐jump setting.
