Deepening the real options debate: Real options as dynamic optimization

open access: yesStrategic 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

On the Quadratic Variation of Two-Parameter Continuous Martingales

open access: yesThe Annals of Probability, 1984
Let M={M(z),z∈[0,1]2} be a two-parameter square integrable continuous martingale. We prove the sample continuity of the quadratic variation of M using an Ito's differentiation formula for M2.

Not all Temperature Shocks are Alike: Disentangling Heat and High Temperature Shocks and Their Effects on Inflation in Australia

open access: yesEconomic Record, EarlyView.
We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Who Moves First? Price Discovery by Institutional and Retail Investors

open access: yesAccounting &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

open access: yesEconomic 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 ...

An application of two-parameter martingales in harmonic analysis [PDF]

open access: yesStudia Mathematica, 1993
Summary: Some duality results and some inequalities are proved for two-parameter Vilenkin martingales, for Fourier backwards martingales and for Vilenkin and Fourier coefficients.

Learning in the Limit: Income Inference from Credit Extensions

open access: yesThe 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%.

Regularities of local times of two-parameter martingales

open access: yesKyoto Journal of Mathematics, 2004
We prove that, as Wiener functionals, local times of two-parameter martingales belong to some fractional Sobolev spaces over the Wiener space and, therefore, exist (2, ∞)-quasi surely.

Functional Vašiček Model

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We propose a new formulation of the Vašičekmodel within the framework of functional data analysis. We treat observations (continuous‐time rates) within a suitably defined trading day as a single statistical object. We then consider a sequence of such objects, indexed by day.

On Selection of Cross‐Section Averages in Non‐Stationary Environments

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT Information criteria (ICs) have been widely used in factor models to estimate an unknown number of latent factors. It has recently been shown that ICs perform well in Common Correlated Effects (CCE) and related settings when selecting a set of cross‐section averages (CAs) sufficient for the factor space under stationary factors.
