Measuring the time‐varying market efficiency in the prewar and wartime Japanese stock market, 1924–1943

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.
Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.

Rural land rental markets in developing countries: Can survey design innovations improve land market participation statistics?

American Journal of Agricultural Economics, EarlyView.
Abstract A longstanding puzzle in the African land rental market literature is the often‐observed discrepancy between the number of tenants (renters‐in) and the much smaller number of landlords (renters‐out) in survey data. If this discrepancy derives from systematic biases in survey data responses on rental market participation, then the existing body

Scale Versus Technology—M&A Effects by Firm Size and Ex‐Post M&A Time Horizon in Korea

Asian-Pacific Economic Literature, EarlyView.
ABSTRACT This study aims to examine the effects of mergers and acquisitions (M&A) on technical change (TC) and the scale component (SC)—the two primary constituents of total factor productivity (TFP)—by firm size and ex‐post M&A time horizon (i.e., short‐term vs. long‐term effects).

The Effects of External Macroeconomic Shocks and Uncertainty on Bangladesh's Fiscal Sustainability

Asian-Pacific Economic Literature, EarlyView.
ABSTRACT In recent years, Bangladesh has adopted a deficit‐biased fiscal policy, supported by robust GDP growth and relatively low interest rates, capitalizing on its access to concessional financing. However, Bangladesh's graduation to lower‐middle‐income status and its gradual integration into the global economy have exposed the country to external ...

Enhancing generalizability theory with mixed‐effects models for heteroscedasticity in psychological measurement: A theoretical introduction with an application from EEG data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Generalizability theory (G‐theory) defines a statistical framework for assessing measurement reliability by decomposing observed variance into meaningful components attributable to persons, facets, and error. Classic G‐theory assumes homoscedastic residual variances across measurement conditions, an assumption that is often violated in ...
