A Test of the Coase Conjecture Using Prices of Electronic Books

Southern Economic Journal, EarlyView.
ABSTRACT The Coase Conjecture predicts that a durable‐goods monopolist without commitment will rapidly cut price toward marginal cost. We test this prediction in the electronic‐book market using release‐day prices. To proxy for marginal cost, we use competitive prices of public‐domain electronic books on the same platforms.

Self-tuning Position Control for the Linear Long-stroke, Compound Switched Reluctance Conveyance Machine

, 2017
This paper proposes a long-stroke linear switched reluctance machine (LSRM) with a primary and a secondary translator for industrial conveyance applications. The secondary one can translate according to the primary one so that linear compound motions can

Managing Competency‐Based Resistance in Video‐Mediated L2 Peer Feedback Sessions

TESOL Quarterly, EarlyView.
Abstract Though there is growing empirical evidence on managing advice resistance as an institutional work of higher status party with superior epistemic knowledge domain (e.g., trainer) across diverse settings (e.g., supervision meetings), there is still a lack of research on how second language (L2) learners handle peer resistance in real time once ...

Inductance estimation method for linear switched reluctance machines considering iron losses

IET Electric Power Applications, 2016
The voltage pulse injection method is widely used at the starting and low‐speed sensorless operation of the rotary switched reluctance machine (SRM) and the linear SRM (LSRM). The conventional methods for the inductance estimation in voltage pulse injection, the current peak value method, and the current slope difference method have a limitation that ...

Proctoring in a Second Language: Exploring Fairness and Justice in Remote English Language Testing

TESOL Quarterly, EarlyView.
Abstract Remote proctoring is increasingly common in English language testing (Isbell & Kremmel, 2020), yet it often requires communication in the target language, unlike in‐person centers that may offer support in test‐takers' first language. Although prior studies have noted communication challenges in remote testing environments (Green & Lung, 2021;

Adoption of Minimum Tillage and Mid‐Season Drainage in Rice Production and Their Impacts on Farm and Economic Performance

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the effects of two greenhouse gas (GHG) mitigation practices—minimum tillage and mid‐season drainage—on rice farmers' farm performance (e.g., crop yield and risk) and economic outcomes (e.g., income and vulnerability).

Awareness–Action and Policy Acceptability in Mitigating Greenhouse Gas Emissions: Key Stakeholders in Germany's Cattle Dairy and Meat Chains

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper presents a systematic literature review and targeted searches to define a synthesis framework mapping the awareness–action gap, progression along the awareness–action continuum and policy acceptability in greenhouse gas (GHG) emissions mitigation among key stakeholders in Germany's cattle dairy and meat chains.

Data‐ and code‐archiving in the British Ecological Society journals: Present status and recommendations for future improvements

Methods in Ecology and Evolution, EarlyView.
Abstract Data‐ and code‐archiving are important components of open science, as both make research more transparent, reproducible, accountable and credible, allowing future researchers to build on previous work. Despite progress in implementing data‐ and code‐archiving policies in journals publishing ecology and evolution research, issues remain.

Buyers' response to third‐party quality certification: Theory and evidence from Ethiopian wheat traders

American Journal of Agricultural Economics, EarlyView.
Abstract When quality attributes of a product are not directly observable, third‐party certification (TPC) enables buyers to distinguish between quality levels and reward sellers accordingly. We study the adoption of TPC by traders in smallholder‐based agricultural value chains in low‐income countries, where traders aggregate products from many small ...
